　A chuck is a mechanical device used to clamp workpieces on machine tools. According to the number of chuck claws, it can be divided into: two-claw chuck, four-claw chuck, six-claw chuck and special chuck. Today we will take a three-jaw chuck as an example to introduce the heat treatment of the jaws using high-frequency induction quenching equipment. The three-claw chuck uses a large wrench to rotate the bevel gear. The bevel gear drives the plane to thread, and then drives the three claws to move centripetally. Since the pitch of the plane rectangular thread is equal, the three claws move at the same distance and have an automatic centering effect. The three-claw chuck is composed of a large bevel gear and three claws. The three claws are equally installed on the flat thread, and the small bevel gear rotates when a wrench is used. The flat thread on the back allows the three claws to move toward or withdraw from the center. The material of the claw is 45 steel, the overall dimensions are 70.3*56*20.5mm, and the tooth width is 12mm. Hardness ≥52HRC, 30-40HRC on both sides and base, 53-58H on the rest Read More »

　　Background technology: The pneumatic chuck has a body accuracy of 0.010mm and a high speed of up to 5000rpm. It is a high-end and high-performance pneumatic chuck with hollow through holes that can work with an automatic feeding system to improve production efficiency. Currently, pneumatic chucks have been widely used in various applications such as workpiece clamping systems for CNC lathes or special processing machines, automation of traditional lathe modifications, grinding machines, or fourth-axis indexing chucks installed in CNC machining centers. However, the traditional pneumatic chuck must rely on manpower when locking the workpiece. Manually tightening the workpiece with a chuck wrench is time-consuming and laborious, which seriously affects production efficiency. During the rotation of the pneumatic chuck, it is easy to cause its own displacement due to the rotation speed, resulting in a short service life of the equipment. Therefore, those skilled in the art provide a rotatable hollow three-jaw pneumatic chuck to solve the problems raised in the above background art. Technical implementation elements: The purpose is to provide a Read More »

The characteristics of movement on machine tools are classified into the following categories: (1) Lathe type fixtures: including fixtures for lathes, internal and external cylindrical grinders, and thread grinders. The characteristic is that the fixture rotates together with the workpiece. (2) Milling machine fixtures: including fixtures for milling machines, planers, surface grinders and other machine tools. The characteristic is that the fixture is fixed on the workbench and only performs longitudinal or transverse reciprocating or rotary motion. (3) Drilling and boring machine fixtures: used for drilling, enlarging, reaming and other processes on the drilling machine or in the boring process. In fact, the fixture is fixed on the machine tool, and the tool is fed through the guide device on the fixture. Read More »

Special fixtures are specially designed and manufactured to meet the requirements of a certain process of processing a certain workpiece. Its functions mainly include the following aspects: 1. Ensure the position accuracy of the processed surface of the workpiece, such as the distance accuracy, parallelism, coaxiality, etc. with other surfaces. For laymen, it is often difficult to achieve precision requirements when using general-purpose fixtures to process workpieces that are more complex and require higher positional accuracy. 2. The process time is shortened, thereby improving labor productivity. The time required to perform a certain process mainly includes the maneuvering time required to process the workpiece and the auxiliary time required to load and unload the workpiece. After using special fixtures, the work of installing workpieces and changing workstations can be greatly simplified. Line drawing and alignment are no longer required, which shortens the auxiliary time of the process and saves the line drawing process, thus improving labor productivity. In production, due to the use of multiple workpieces Read More »

An indexing chuck is a mechanical device in a machine tool used to clamp workpieces. A mechanical attachment that secures and positions the workpiece using uniform radial movement of the movable jaw on the card body. The chuck usually consists of three parts: the card body, the movable jaw and the jaw driving mechanism. The diameter of the card body is at least 65 mm and more is 1500 mm, and there is a hole in the center through which the workpiece or bat can pass. There is a cylindrical or short tapered structure on the back, which is connected to the end of the machine tool spindle directly or through a flange. Clamps are commonly installed on lathes, cylindrical grinders and internal cylindrical grinders and can be used with a variety of indexing devices that can be used for milling and drilling. A 'chuck' is a mechanism used to clamp workpieces on a machine tool. What are the classifications of indexing chucks? In terms of the number of claws, it can be divided into two claws, three claws, four claws, six claws, special claws, etc. The power used can be divided into manual chuck, pneumatic chuck, hydraulic chuck, electric chuck, mechanical chuck, etc. Structurally it can be divided into blanks Read More »

Characteristics of fixtures When processing workpieces on machine tools, we can see two different situations: one is to use a measuring tool such as a needle or indicator to align according to a certain surface of the workpiece, or according to the line drawn on the surface of the workpiece, so that the workpiece is in the correct position required on the machine tool, and then clamp the workpiece for processing; the other is to install the workpiece on a fixture for processing. In order to process a surface that meets the specified technical requirements on a certain part of the workpiece, various devices are generally used to accurately, conveniently and reliably install the workpiece on the machine tool according to the structural shape of the workpiece, the processing method and the production batch, and then process it. The device used to install the workpiece to determine the relative position of the workpiece and the cutting tool and clamp the workpiece is called a 'machine tool fixture'. In actual production, such as piston and connecting rod production lines, fixtures are used in almost every process. It is very obvious that if the clamp is not used, not only Read More »

　　01. Selection of soft claw material: The 'soft' here means: good processing performance, but it does not mean that it must be lower than the hardness of the workpiece. For mass production, the hardness of the soft claw will have a great impact on the stability of processing. Choosing a soft claw material with a higher hardness than the workpiece will not only increase the service life of the soft claw, but also have a positive impact on the stability of processing. 02. The installation position of the soft claw on the chuck: Any T-shaped block exceeding the maximum diameter of the chuck is not allowed, which will cause great safety risks. 03. Pressure and position when using the claw trimmer: It is recommended that the pressure during use is close to the pressure during workpiece processing. The chuck is in the middle of the range of movement during processing, and the direction of the clamping force during claw trimming is consistent with the direction of the workpiece clamping force.

　　CNC pneumatic three-jaw chuck, specifically involves a three-jaw built-in CNC chuck. Technology introduction: Three-jaw chuck is also called three-jaw self-centering chuck. Depending on the position of the jaws, the three-jaw chuck can be roughly divided into external and internal types. At present, the principle of clamping the workpiece by the jaws of the built-in CNC chuck is similar to the expansion screw. The workpiece needs to be placed in the chuck, and then the direction of the clamping point of the clamping jaw points to the center of the chuck using the screw. A chuck with this structure takes a lot of time to clamp a workpiece once, and the work efficiency is low. Technical implementation idea: The technical solution to be solved is to provide a three-jaw built-in CNC chuck, which can quickly clamp workpieces. The technical solution is implemented as follows: a three-claw built-in CNC chuck includes a circular body, a circular groove is provided upward on the back of the circular body, the notch of the circular groove is covered with a circular cover plate, and the center of the circular cover plate is provided Read More »

　The precision three-jaw self-centering chuck is an industrial product with automatic centering function. 1. Use a voltaic wrench to rotate the bevel gear. The bevel gear drives the flat rectangular thread, and then drives the three claws to move centripetally. Because the pitch of the flat rectangular thread is equal, the movement distance of the three claws is equal, which has the effect of automatic centering. 2. Installation of the three-jaw self-centering chuck: (1) Loosen the three positioning screws and take out the three small bevel gears; (2) Loosen the three fastening screws and take out the dust cover and the large bevel gear with flat threads; (3) When installing the chuck, insert the square tenon of the chuck wrench into the square hole of the small bevel gear and rotate it to drive the flat thread of the large bevel gear to rotate. When the screw thread of the flat thread is turned to be close to the housing groove, install the No. 1 catch into the housing groove. The remaining two cards are loaded in the order of No. 2 and No. 3. The installation method is the same as before.
