If the three-jaw pneumatic chuck is used incorrectly or with inappropriate lubrication, it is more likely to cause problems. For example, it will not work properly at low pressure, so the power chuck must be lubricated correctly. In addition, the workpiece is heavy, so it is better to use four-claw processing. Just move each of the four claws outward a little. In this way, the distance between the legs is larger than the outer circle of the workpiece. Then place the round workpiece between the four claw feet. At the same time, place 2 nuts on two of the four claws. You can place this nut anywhere, horizontally or vertically. The principle of placing the nut is that the diameter of the round workpiece plus the thickness of the nut is greater than the original distance between the two claws.

Under the influence of the hydraulic oil, it presses the oil cylinder to hold the workpiece, and the two indexing oil cylinders move in reverse direction, pushing the indexing plate to rotate counterclockwise to complete the indexing of the workpiece. Special fixture: a fixture that can be used for different workpieces. Combination fixture: The operating principle and characteristic definition of the combination fixture: It is a new type of process equipment developed on the basis of the standardization of machine tool fixture components. It is assembled from a set of specialized components and components whose structure and size have been standardized, serialized and standardized. It can be seen that the combination fixture is only a practical fixture that can be reused many times. The production practice has shown that it is equivalent to a special fixture for one-time use. It covers R&D and production with assembly, so it has the following characteristics: flexibility, wide application range, and can greatly shorten the production preparation distance. It can save a lot of manpower and material resources and reduce the consumption of metal materials. It can greatly reduce the warehouse area for storing public fixtures and simplify management operations. Disadvantages: Larger appearance and bulky.

Because the workpiece is heavy, use the tailstock to support the workpiece. In this way, small round workpieces can be adjusted on the four claws. Be careful to adjust your feet slowly to prevent the nuts from falling out. After adjustment, tighten the four claws. Precautions When adjusting, pay attention to the nut of the pad to prevent it from falling. Every 6 months, remove the chuck, disassemble it, clean it (keep the sliding surface of the clamp jaw clean), and lubricate it. If you are cutting cast iron, clean it thoroughly at least once or multiple times every 2 months and check all parts for cracks and wear (replace the severely worn parts immediately). After the inspection is completed, the oil must be fully supplied before assembly.

Immediate improvement of accuracy 1. When replacing the upper claw, it is necessary to clean the toothed part of the base claw and the joint part of the T-type nut, otherwise it will cause inaccuracy in accuracy. When clamping beveled or tapered iron workpieces, the special claws used need to have a toothed clamping surface so that the workpiece is not easily scattered. When clamping an eccentric workpiece, the centrifugal force generated by the eccentric component acts on a single claw, and low speed is required during processing. Before starting the work, do a test run at low speed to check whether the position of the upper claw and the workpiece interferes with the tool and tool holder. When the instrument is parked for a long time, the chuck does not take into consideration the clamping of the workpiece. When improper operation or mechanical failure causes the tool or tool holder to hit the chuck, stop the machine immediately and check whether the upper jaw, base jaw, T-nut, connecting screw and clamping accuracy are normal. The hydraulic pressure required for the use of special height upper claws is lower than that of standard upper claws.

Doing a good job of lubrication can ensure that the lathe chuck still has good accuracy after long-term use. However, incorrect or inappropriate lubrication will cause some problems, such as abnormal function at low pressure, weakened clamping force, poor clamping accuracy, abnormal wear and jamming, so the chuck must be lubricated correctly. After working on the chuck, be sure to use wind or similar tools to clean the chuck body and slide surface. Using anti-rust cutting oil can prevent rust inside the chuck, because rust in the chuck will reduce the clamping force and prevent the workpiece from being held. Apply molybdenum disulfide grease (black in color) at least once a day, and drive the grease into the chuck oil nozzle until the grease overflows the jaw surface or the inner hole of the chuck (the inner hole protective sleeve and the connecting nut).

When we later process precision mechanical parts, the shapes occasionally come in different shapes. Now we need to customize some fixtures according to actual needs to meet the needs of the precision machining industry. How to design customized fixtures has become a question we need to consider. The combined fixture is assembled from a set of pre-developed and produced standard components and parts of different shapes, specifications and sizes. The selection process of the combined fixture is to assemble the fixture by selecting a set of pre-designed and produced standard components of different shapes, specifications and sizes. The assembled fixture is mainly used in CNC precision machining. Generally speaking, the assembled fixture is mainly Composed of basic fixture parts and other modular components, assembled fixtures and combination fixtures have many similarities, and many of their basic parts are regular. The surface of the basic parts is distributed with grid holes or slotted holes, etc., which later makes the fixture more standardized. Both combination fixtures and assembled fixtures can be configured into flexible fixtures, and the strategy of creating flexible fixtures mainly refers to the creation, design and production of fixtures.
