The operation of CNC machinery and equipment is inseparable from the chuck.
The pneumatic chuck can ensure the accuracy of the lathe equipment. It has the advantages of simple structure, safety,
and labor-saving installation. So how should the pneumatic chuck be installed? What are the advantages compared with ordinary chucks? Let's take a look.
1. Advantages and characteristics of pneumatic chucks
1. Compared with ordinary chucks, the working efficiency of pneumatic chucks will be greatly improved,
such as in clamping. And the practical life will be much longer.
2. The structure of pneumatic chucks is very simple, without those cumbersome and 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, this is a very eye-catching advantage, which can be called no consumption.
And it is environmentally friendly and pollution-free, which is an extremely practical and superb advantage today when environmental pollution is increasing.
4. The safety factor is extremely high. In the machinery industry, everyone knows that safety is an important item.
Therefore, pneumatic chucks have strict factory inspections, pressure tests, and error tests, which are all zero-risk.
Therefore, pneumatic chucks can be accepted and used by the majority of users in the field
2. Instructions for installing pneumatic chucks
1. Take out the connecting sleeve, screw on the screws, connect it to the tail of the spindle,
use a dial indicator to calibrate the outer circle and end face runout of the connecting sleeve to within 0.05MM, and lock the screws.
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 not, please fine-process the flange according to the size of the chuck.
3. Take out the spiral air pipe, put on the decorative hoop, and install the air pipe on the vent nozzle of the chuck.
Then clamp the hoop with a vise, and do not damage the air pipe during installation.
4. Wrap the air pipe in sections with capsules to ensure smoothness, and then mark No. 1 and No. 2 at the tail of the air pipe.
Then use a thin wire to tie the air pipe through the lathe spindle, so that the air pipe passes smoothly through the spindle,
and support the chuck to move backward synchronously and lightly buckle on the flange.
5. Take out the screws, fix the chuck on the flange, and measure the outer circle runout ≦0.05.
6. Tighten the air pipe, cut off the excess air pipe at the tail, and reserve about 50-100MM outside the spindle.
And it can naturally rebound into the spindle, then try to blow the No. 1 and No. 2 air pipes to observe whether the chuck moves smoothly.
7. Put on the hoop, respectively connect the No. 1 and No. 2 air pipes with the No. 1 and No. 2 air nozzles on the pneumatic rotator, and then clamp the hoop.
8. Thread the pneumatic rotator and the connecting sleeve and rotate, then try to blow the No. 1 and No. 2 air holes.
Observe whether the chuck moves smoothly to prevent the air pipe at the pneumatic rotator from twisting.
9. Fix the "anti-rotation screw" at the bottom of the pneumatic rotator to prevent it from rotating with the spindle.
10. First fix the circuit board and switch on the lathe, close to the pneumatic rotator,
and then connect the air pipes one by one, and introduce the power supply 220V or 24V.
11. Fill the oil reservoir on the oil-water separator, adjust the pressure and oil output, power on the machine tool, operate the switch, and the chuck moves smoothly.
