If there are iron filings between the lower surface of the parts and the plane of the fixture, the air leakage will increase, and the machine tool will alarm and stop. If there is no alarm, the parts will start to be processed; finally, after the parts are processed, the multiple clamping mechanisms respectively release the parts on the multiple positioning blocks, and multiple cleaning mechanisms are used to perform cleaning operations to clean up the iron filings on the fixture and the parts, thereby ensuring the quality of the parts processing.

[0109] The working principle of the present invention is as follows:

[0110] During the material taking process, first, the material taking cylinder 20 is extended and retracted to drive the support plate 19 to move horizontally to the bottom of the corresponding pallet 18; then, the motor 26 drives the screw rod 27 to rotate, and the screw rod 27 converts its own rotation into the up and down movement of the nut and the support plate 19 thereon, so as to send the support plate 19 to a set height to hold the corresponding pallet; finally, the material taking cylinder 20 is extended and retracted to drive the support plate 19 to move to the bottom of the loading port, and at the same time, the motor 26 drives the screw rod 27 to rotate, so as to send the support plate 19 and the pallet 18 thereon to the loading port;

[0111] A loading robot 16 is used to place multiple parts 5 to be processed on multiple positioning blocks 3, and multiple clamping mechanisms are used to respectively press the parts 5 placed on the multiple positioning blocks 3; then, a set instrument is used to perform an airtightness test on the pressed parts 5. If there are iron filings between the lower surface of the part 5 and the plane of the fixture, the air leakage will increase, and the machine tool will alarm and stop. If there is no alarm, the part processing will begin; finally, after the parts processing is completed, the multiple clamping mechanisms respectively release the parts 5 on the multiple positioning blocks 3, and multiple side air knives 8 and multiple center air knives 9 are used to perform cleaning operations to clean up the iron filings on the fixture and the parts 5 to ensure the quality of the part 5 processing.

[0112] The beneficial effects of the present invention are as follows:

[0113] 1. The center air knife performs center air blowing to prevent iron filings from affecting positioning accuracy;

[0114] 2. Air tightness detection prevents padding and improves the pass rate;

[0115] 3. Hydraulic automatic fixture, multi-station processing efficiency is higher;

[0116] 4. The loading and unloading of the robot reduces the labor intensity, and one person can operate multiple machines.

[0117] 5. In the integrated workstation mode, all silos, robots, loading and unloading mechanisms and multi-layer automated silos are integrated into one workstation, which can be quickly arranged and moved.

[0118] 6. Adopting the automated silo structure, the multi-layer silos can hold more parts.

[0119] 7. In the integrated workstation mode, all silos, robots, loading and unloading mechanisms, and multi-layer automated silos are integrated into one workstation, which can be quickly arranged and moved.

[0120] 8. Standardized pallets can adapt to a variety of automated equipment and parts loading.

[0121] It should be noted that all electronic components involved in the present invention adopt the existing technology, and the above-mentioned components are electrically connected to the controller, and the control circuit between the controller and each component is the existing technology.
