[0032] The device starts the third motor 20, which drives the disc 22 to rotate. The disc 22 synchronously drives the transverse movement mechanism, the longitudinal movement mechanism and the polishing head 6 to rotate through the cooperation of the connecting column 23 and the semicircular through groove 21, thereby adjusting the polishing angle of the polishing head 6.

[0033] The pushing assembly includes a pushing cylinder 24 and a connecting rod 25. The pushing cylinder 24 is fixedly provided at the lower end of the support plate 2. The output end of the pushing cylinder 24 is fixedly connected to the base plate 8. Connecting rods 25 are provided on both sides of the pushing cylinder 24. The connecting rods 25 penetrate the support plate 2 and are slidably connected to the support plate 2. One end of the connecting rod 25 is fixedly connected to the base plate 8.

[0034] By starting the push cylinder 24, the push cylinder 24 pushes the bottom plate 8 to move on the top of the working chamber 1, and at the same time the connecting rod 25 moves synchronously to provide auxiliary support for the clamping assembly. After the clamping assembly is pushed out, it is convenient for the staff to place the workpiece.

[0035] The transverse movement mechanism includes a mounting plate 5, a threaded rod 27, a limiting rod 29, a nut sleeve 28 and a fourth motor 30. The mounting plate 5 is symmetrically provided with two groups. A threaded rod 27 is rotatably installed between the two groups of mounting plates 5. The limiting rod 29 is fixed between the four corners of the two groups of mounting plates 5. A nut sleeve 28 is threadedly installed on the threaded rod 27. The four corners of the nut sleeve 28 are slidably connected to the limiting rod 29. The outer wall of one group of mounting plates 5 is fixedly connected to the connecting rod 25, and the fourth motor 30 is fixed on the outer wall of the other group of mounting plates 5.

[0036] By starting the fourth motor 30 , the fourth motor 30 drives the threaded rod 27 to rotate, and the nut sleeve 28 is limited by the limiting rod 29 , so that the nut sleeve 28 moves horizontally, thereby driving the polishing head 6 to move horizontally.

[0037] The vertical movement mechanism includes a pneumatic cylinder 31 and a lifting seat 32 . The lower end of the lifting seat 32 is slidably connected to the nut sleeve 28 .

[0038] By starting the pneumatic cylinder 31, the pneumatic cylinder 31 pushes the lifting seat 32 to move up and down on the nut seat, thereby driving the polishing head 6 to move up and down for height adjustment.

[0039] Two groups of industrial cameras 49 are symmetrically distributed at the bottom of the fixing plate 33 with the threaded rod 27 as the symmetry axis. A control panel 50 is provided on one side of the work chamber 1. The industrial cameras 49 are connected to the control panel 50 and scan the shape of the workpiece.

[0040] The device uses an industrial camera 49 to take pictures from both sides of the workpiece. By generating images from both sides and then stitching them together, the problem of incomplete imaging caused by occlusion can be prevented. At the same time, the polishing action is pre-stored in the control panel 50, and the polishing action is pre-stored by the staff according to the shape of the workpiece. When polishing, the control panel 50 determines the shape of the workpiece through the imaging of the industrial camera 49, and thus calls up the corresponding polishing action. Professional polishing can be performed to ensure the polishing effect. At the same time, for some special-shaped workpieces, the staff can design and replace the polishing action by themselves, thereby increasing the human-computer interactivity and the use effect of the device.

[0041] The working chamber 1 is provided with a liquid guide port 36, a liquid collecting chamber 37, a polishing shavings collecting chamber 38, a filter screen plate 39, a tooth plate 40, a gear 41 and a fifth motor 42 inside.

A liquid collecting chamber 37 is provided directly below the liquid guide port 36 and below the filter screen plate 39. Polishing shavings collecting chambers 38 are provided on both sides of the liquid collecting chamber 37. A tooth plate 40 is fixed to the rear side of the filter screen plate 39, and a gear 41 is meshed below the tooth plate 40. The gear 41 is driven by a fifth motor 42 fixedly connected to the inner wall of the working chamber 1. A cleaning assembly is provided on the filter screen plate 39, and baffles 48 are symmetrically provided on the top of the polishing shavings collecting chamber 38.

[0042] The device guides the polishing chips and polishing liquid to the filter plate 39 by setting a liquid guide port 36. The filter plate 39 has two groups of filter ports, one group for metal polishing filtration and the other group for plastic polishing filtration. At the same time, there are two groups of polishing chip collection bins 38, one group for collecting metal polishing chips and the other group for collecting plastic polishing chips. By classifying and collecting the two groups of polishing chips, subsequent recycling and reuse are facilitated. The device starts the fifth motor 42, and the fifth motor 42 drives the gear 41 to rotate, thereby driving the tooth plate 40 to move, and then drives the filter plate 39 to move, and stops after contacting the baffle 48, so as to classify and collect according to the different materials of the workpieces, further increasing the functionality of the device and reducing the polishing cost.

[0043] The cleaning assembly includes a cleaning plate 43, an adjusting screw 44, a sixth motor 45, an adjusting plate 46 and an electromagnetic adsorption head 47.

[0045] When the polishing device for machining mechanical parts is in use, the pushing cylinder 24 is first started, and the pushing cylinder 24 pushes the bottom plate 8 to move on the top of the working bin 1. At the same time, the connecting rod 25 moves synchronously to provide auxiliary support for the clamping assembly. The clamping assembly is pushed out, and the staff loads the workpiece at this time. The two groups of clamping blocks 13 are driven to move up and down oppositely by the second driving assembly, and one end of the plate-shaped or tubular workpiece is clamped and fixed by clamping or tensioning fixation between the upper and lower parts. Then, the bidirectional screw 15 is driven to rotate by the second motor 16, thereby driving the two groups of movable plates 10 to move oppositely, thereby driving the two groups of tensioning clamps to move oppositely, so that the tensioning clamp clamps the other end of the workpiece. Then, the pushing cylinder 24 drives the clamping assembly to reset, and then the second motor 16 is started to drive the two-way screw 15 to rotate, thereby driving the two groups of movable plates 10 to move oppositely, thereby driving the two groups of tensioning clamps to move oppositely, so that the tensioning clamps clamp and fix the other end of the workpiece. The fourth motor 30 is driven, and the fourth motor 30 drives the threaded rod 27 to rotate. The nut sleeve 28 is limited by the limiting rod 29, so that the nut sleeve 28 moves horizontally, thereby driving the polishing head 6 to move horizontally, and cooperating with the pneumatic cylinder 31 to push the lifting seat 32 to move up and down on the nut seat, thereby driving the polishing head 6 to move up and down for height adjustment. At the same time, the third motor 20 drives the disc 22 to rotate. The disc 22 drives the polishing head 6 to rotate synchronously through the connecting column 23 and the semicircular through groove 21, thereby adjusting the polishing angle of the polishing head 6, and then performing a comprehensive polishing process on the upper surface of the workpiece. When it is necessary to polish the back side of the workpiece, the first motor 11 is started, and the first motor 11 drives the workpiece to flip, thereby polishing the back side of the workpiece.
