[0030] In the technical scheme of the utility model, by not needing to carry out complex processing or additionally setting up additional sensor and connecting mechanism to quick change disc main body 1, the change of the gas pressure in clamping gas supply pipeline 2 can be monitored, whether ejector rod piston 104 reaches the completely loosening or clamping position is accurately judged, simultaneously avoids the problems, such as monitoring failure, sensor damage and sealing ring damage, caused by processing or installation error, and the driving mechanism runs stably without the risk of jamming, ensures the accuracy and reliability of gas pressure monitoring, and two gas pressure detection switches can be installed with electromagnetic valve 5 near the external equipment control cabinet, reduces the wiring and pipe connection demand on the quick change disc main body 1 of robot.

[0031] In addition, the positioning pin 106 can fix the main shell 101 and the flange 102, the spring 103 can slowly lower the top rod piston 104, the top rod piston 104 can fix the driving disc 105, the limiting channel 1021, the clamping groove 1051 and the limiting convex point 1052 can accommodate the steel ball 107, and the clamping groove 1051 and the limiting convex point 1052 can self-lock the steel ball 107.

[0032] In the technical scheme of the utility model, as shown in Figure 2 The first sealing ring 108 is arranged on the outer wall of the top rod piston 104, and the first sealing ring 108 is in sliding connection with the inner wall of the main shell 101, so that the top rod piston 104 and the main shell 101 are sealed; the inner and outer walls of the flange 102 are respectively provided with the second sealing ring 109, and the two second sealing rings 109 are in contact with the inner wall of the main shell 101 and the top rod piston 104, so that the flange 102, the main shell 101 and the top rod piston 104 are sealed.

[0033] In the technical scheme of the utility model, as shown in Figure 1 The two clamping air supply pipes 2 located on the outer wall of the quick-change disc main body 1 are different in height, and the clamping air supply pipe 2 at the clamping channel air pressure pressure detection switch 3 is slightly higher than the clamping air supply pipe 2 at the loosening channel air pressure pressure detection switch 4, so that the clamping air supply pipe 2 at different heights can conveniently inflate and replace air at different positions of the quick-change disc main body 1.

[0034] In use, first, the quick-change disc main body 1 is in an unclamped state, the top rod piston 104 is supported by the spring 103 in the main shell 101 and maintains a certain height, at this time, the clamping channel air pressure pressure detection switch 3 and the loosening channel air pressure pressure detection switch 4 do not detect that the air pressure reaches 0.6MPA.

[0035] Inflation process:

[0036] When clamping is needed, the external air source inflates the inside of the quick-change disc main body 1 through the higher clamping air supply pipe 2 at the clamping channel air pressure pressure detection switch 3; the gas pushes the top rod piston 104 to move downward, and at the same time, the spring 103 is compressed, and in the process of the top rod piston 104 descending, the first sealing ring 108 and the second sealing ring 109 ensure that the gas does not leak, and the sealing property of the system is maintained.

[0037] Clamping state monitoring:

At this time, the electromagnetic valve 5 operates according to the signal of the detection switch, such as locking the cylinder position or sending a signal that the clamping is complete.

[0039] Ventilation process:

[0040] When it needs to be released, the external air source releases the channel air pressure pressure detection switch 4 through the lower clamping gas supply pipeline 2 to perform ventilation operation. The gas pushes the top rod piston 104 to move upward, and the spring 103 gradually recovers to its original state.

[0041] Release state monitoring:

[0042] When the top rod piston 104 reaches the fully released position, the air pressure in the release channel reaches 0.6MPA, triggering the release channel air pressure pressure detection switch 4. The electromagnetic valve 5 again operates according to the signal of the detection switch, such as unlocking the cylinder position or sending a signal that the release is complete.

[0043] Cyclic use:

[0044] The quick change disc main body 1 can be used cyclically between the clamped and released states. By continuously monitoring the air pressure change in the clamping gas supply pipeline 2, the accuracy of the top rod piston 104 position is ensured. At the same time, since the two air pressure pressure detection switches can be installed together with the electromagnetic valve 5 near the external equipment control cabinet, the wiring and pipe connection requirements on the quick change disc main body 1 are reduced, improving the flexibility and maintainability of the system.

[0045] In the entire workflow, through accurate air pressure monitoring and stable operation of the driving mechanism, the accuracy and reliability of the quick change disc piston position air pressure pressure monitoring device are ensured.
