The operation of CNC mechanical equipment is inseparable from the chuck, and the pneumatic chuck can ensure the accuracy of the lathe equipment. It has the advantages of simple structure and labor-saving installation. So how should the pneumatic chuck be installed? What are its advantages compared to ordinary chucks?
1. Compared with ordinary chucks, the working efficiency of pneumatic chucks will be greatly improved, such as in clamping. And the practical lifespan will be much longer in comparison.
2. The structure of the pneumatic chuck is very simple and there are no complicated parts and components, so the installation is very convenient and labor-saving, and it is not easy to cause mistakes.
3. In terms of consumables and energy, it can be called no consumption. It is also environmentally friendly and has no pollution, which is a practical and superb advantage today when environmental pollution is increasing day by day.
4. In the machinery industry, everyone knows that safety is the most important thing. Therefore, pneumatic chucks undergo strict factory testing, pressure testing, and error testing, all of which are zero-risk. Therefore, the pneumatic chuck can be accepted and used by the majority of users in the field.
1. Take out the connecting sleeve, screw on the screw, connect it to the end of the spindle, use a dial indicator to correct the outer circle and end face runout of the connecting sleeve to within 0.05MM, and tighten the screw.
2. Take out the chuck, wipe it clean with a rag, and use a caliper to measure whether the lathe flange size matches the connection size of the chuck. If they do not match, please finish the flange according to the chuck size.
3. Take out the spiral air pipe, put on the ornamental hoop, and install the air pipe on the ventilation joint of the chuck. Then use a vise to clamp the hoop. Do not damage the air pipe during installation.
4. Wrap the trachea in sections with capsules to ensure smoothness, and then mark No. 1 and No. 2 at the end of the trachea. Then use a thin wire to tie the air pipe through the lathe spindle, so that the air pipe can pass through the spindle smoothly, and hold the chuck synchronously to move backward and lightly buckle it on the flange.
5. Take out the screws, fix the chuck on the flange, and measure the outer diameter runout ≦0.05.
6. Tighten the air pipe, cut off the excess air pipe at the tail, and leave a length of about 50-100MM outside the main shaft. And it can naturally bounce back into the spindle, and then try blowing the No. 1 and No. 2 air pipes to see if the chuck moves smoothly.
7. Set up the hoop, connect the No. 1 and No. 2 air pipes to the No. 1 and No. 2 air nozzles on the pneumatic gyrator respectively, and then clamp the hoop.
8. Connect the air pressure rotor to the thread of the connecting sleeve and rotate it, and then try to blow the No. 1 and No. 2 air holes. Observe whether the chuck moves smoothly to prevent the air pipe from being twisted at the pneumatic rotator.
9. Fix the 'anti-rotation screw' at the bottom of the pneumatic gyrator to prevent it from rotating with the spindle.
10. First fix the circuit board and switch on the lathe, close to the pneumatic gyrator, then connect the air pipes one by one, and introduce the power supply of 220V or 24V.
11. Fill the oil reservoir on the oil-water separator, ventilate and adjust the pressure and oil output, power on the machine tool, operate the switch, and the chuck moves smoothly.
