[0003] During the process of machining mechanical parts, it is often necessary to use a polishing device to polish the surface thereof. Since the shapes of mechanical parts vary, general polishing devices can only perform polishing operations on a specific shape of mechanical parts, and their functions are also relatively single.

[0004] Therefore, when performing a large number of part polishing operations, using traditional polishing equipment incurs a relatively large cost investment. Thus, the present invention proposes a polishing device for machining mechanical parts to solve the problems existing in the prior art. Summary of the Invention

A fixed plate 33 is provided on the top of the support plate 2, and a polishing liquid tank 34 is provided on the fixed plate 33. The polishing liquid tank 34 is communicated with the polishing liquid outlet 7 through a water pump and a hose 35;

[0030] This device drives the polishing mechanism to rotate through the first rotating assembly, so that the polishing mechanism can conveniently polish the side of the workpiece. Especially when polishing rectangular plate-like workpieces, the adjustment of its angle can better polish the side of the workpiece and the connection between surfaces. The setting of the pushing assembly can push out the clamping assembly, thus facilitating the feeding of the workpiece;

The mounting plate 5 is also provided with a polishing liquid outlet 7;

[0032] Through the transverse movement mechanism, this device can drive the polishing head 6 to move horizontally, while the longitudinal movement mechanism can drive the polishing head 6 to move vertically. Combined with the first rotating component, it can perform multi-directional and comprehensive automatic polishing treatment on the upper surface of the workpiece;

[0033] The clamping component includes a bottom plate 8, a drive chamber 9, a first drive component, a moving plate 10, and a tensioning clamp. There are two groups of bottom plates 8 symmetrically arranged. The top of the two groups of bottom plates 8 is symmetrically provided with drive chambers 9. A moving plate 10 is symmetrically arranged between the two groups of drive chambers 9. The drive chamber 9 is internally provided with a first drive component for driving the two moving plates 10 to move. Tensioning clamps are rotatably installed on the inner sides of the two moving plates 10. A first motor 11 for driving the tensioning clamp to rotate is provided on the outer wall of one of the moving plates 10.

[0034] This device drives the two moving plates 10 to move towards each other through the first drive component, thereby driving the tensioning clamp to move, so as to clamp workpieces of different lengths, further increasing the scope of use of this device. At the same time, the tensioning clamp is a rotatable structure. Therefore, when polishing some workpieces that need to be polished on both sides, it can be automatically flipped through the first motor 11, further increasing the convenience of this device.

[0035] The tensioning clamp includes an adjustment chamber 12, clamping blocks 13, and protective soft pads 14. The adjustment chamber 12 is vertically arranged. Two groups of clamping blocks 13 are slidably installed inside the adjustment chamber 12, and the two groups of clamping blocks 13 are symmetrically arranged. The inside of the adjustment chamber 12 is provided with a second drive component for driving the two groups of clamping blocks 13 to move towards each other. The clamping blocks 13 are coated with protective soft pads 14.

[0036] The working principle of the second drive component is the same as that of the first drive component and will not be described in detail here. This device drives the two groups of clamping blocks 13 to move towards each other up and down through the second drive component, and clamps and fixes or tension-fixes the plate-shaped or tubular workpieces through the clamping and fixing between the upper and lower parts, greatly increasing the scope of application of this device. And this device is provided with protective soft pads 14 on the clamping blocks 13, which can prevent the clamping blocks 13 from damaging the surface of the workpiece when fixing the workpiece, thereby ensuring the yield rate of the workpiece.

[0037] The first driving assembly includes a bidirectional screw 15, a second motor 16, a guide rod 17, a chute 18, and an elastic retaining net 19.

[0038] The device drives the bidirectional screw 15 to rotate through the second motor 16, thereby driving the two moving plates 10 to move towards each other, and then driving the two tensioning jigs to move towards each other. And the device does not affect the downward flow of the polishing liquid by arranging two sets of driving bins 9 and setting the moving plate 10 and the tensioning jigs between the two sets of drives. At the same time, an elastic retaining net 19 is also provided in the chute 18 of the driving bin 9, which can prevent polishing debris from entering the inside of the driving bin 9, and there is no need to regularly clean the chute 18 of the driving bin 9.

[0039] The first rotating assembly includes a third motor 20, a semi-circular through groove  21, a disc 22, and a connecting column 23. A semi-circular through groove 21 is provided at the upper end of the support plate 2. A disc 22 is rotatably installed on the outer wall of the support plate 2. The center of the disc 22 and the center of the semi-circular through groove 21 are located on the same straight line. A third motor 20 that drives the disc 22 to rotate is fixed on the inner wall of the support plate 2. A connecting column 23 is provided on the semi-circular through groove 21. One end of the connecting column 23 is fixedly connected to the disc 22, and the other end of the connecting column 23 is fixedly connected to the transverse movement mechanism.

[0040] The device starts the third motor 20, and the third motor 20 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 semi-circular through groove 21, so as to adjust the polishing angle of the polishing head 6.

[0041] 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 bottom plate 8. Connecting rods 25 are provided on both sides of the pushing cylinder 24. The connecting rods 25 penetrate through 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 bottom plate 8.

[0042] By starting the pushing cylinder 24, 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 rods 25 move synchronously to assist in supporting the clamping assembly. After the clamping assembly is pushed out, it is convenient for the staff to place the workpiece.

[0043] 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. There are two sets of symmetrically arranged mounting plates 5. A threaded rod 27 is rotatably installed between the two sets of mounting plates 5. Limiting rods 29 are fixed between the four corners of the two sets 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 set of mounting plates 5 is fixedly connected to a connecting rod 25, and a fourth motor 30 is fixed on the outer wall of the other set of mounting plates 5.

[0044] By starting the fourth motor 30, the fourth motor 30 drives the threaded rod 27 to rotate. Through the limitation of the nut sleeve 28 by the limiting rod 29, the nut sleeve 28 moves horizontally, thereby driving the polishing head 6 to move horizontally.

[0045] 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. The nut sleeve 28 is located inside the lifting seat 32. A pneumatic cylinder 31 is fixed between the top of the nut sleeve 28 and the top of the lifting seat 32.

[0046] 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.

[0047] Two industrial cameras 49 are symmetrically distributed at the bottom of the fixed plate 33 with the threaded rod 27 as the axis of symmetry. A control panel 50 is provided on one side of the working chamber 1. The industrial cameras 49 are connected to the control panel 50 and scan the shape of the workpiece.

[0048] This device takes pictures of the workpiece from both sides through the industrial cameras 49. By generating images from both sides and then splicing them, the problem of incomplete imaging caused by occlusion can be prevented. At the same time, according to the polishing actions pre-stored in the control panel 50, which are pre-stored by the staff according to the shape of the workpiece. During the polishing work, the control panel 50 determines the shape of the workpiece through the imaging of the industrial cameras 49, and then retrieves the corresponding polishing actions. It can not only perform professional polishing to ensure the polishing effect, but also for some special-shaped workpieces, the staff can design and replace the polishing actions by themselves, thereby increasing the human-machine interaction of this device and the use effect of this device.

[0049] Inside the working bin 1, there are a liquid guide port 36, a liquid collection bin 37, a polishing debris collection bin 38, a filter mesh plate 39, a toothed plate 40, a gear 41, and a fifth motor 42. A liquid guide port 36 is provided directly below the grid plate 3. A filter mesh plate 39 is provided below the liquid guide port 36. The filter mesh plate 39 is symmetrically distributed with two groups of filter ports. The position directly below the liquid guide port 36 and below the filter mesh plate 39 is provided with a liquid collection bin 37. Polishing debris collection bins 38 are provided on both sides of the liquid collection bin 37. A toothed plate 40 is fixed to the rear side of the filter mesh plate 39. The toothed plate 40 is engaged with a gear 41 below it. The gear 41 is driven by a fifth motor 42 fixedly connected to the inner wall of the working bin 1. A cleaning component is provided on the filter mesh plate 39. Baffles 48 are symmetrically provided at the top of the polishing debris collection bin 38.

[0050] This device guides the polishing debris and polishing liquid through the liquid guide port 36 and directs them to the filter mesh plate 39. The filter mesh plate 39 has two groups of filter ports. One group is for metal polishing filtration, and the other group is for plastic polishing filtration. At the same time, there are two groups of polishing debris collection bins 38. One group is for collecting metal polishing debris, and the other group is for collecting plastic polishing debris. By classifying and collecting the two groups of polishing debris, it is convenient for subsequent recycling and reuse. This device starts the fifth motor 42. The fifth motor 42 drives the gear 41 to rotate, thereby driving the toothed plate 40 to move, and then driving the filter mesh plate 39 to move. It stops after contacting the baffle 48. Thus, according to the different materials of the workpieces, classification collection is carried out, further increasing the functionality of this device and reducing the polishing cost at the same time.

[0051] The cleaning component includes a cleaning plate 43, an adjusting screw 44, a sixth motor 45, an adjusting plate 46, and an electromagnetic adsorption head 47. The cleaning plates 43 are symmetrically distributed at the middle end of the filter mesh plate 39 and are magnetically fixed. Adjusting screws 44 are symmetrically and rotatably installed on the inner wall of the working bin 1. The adjusting screws 44 are driven by a sixth motor 45. One end of the adjusting plate 46 is threadedly connected to the adjusting screw 44 and is slidably connected to the inner wall of the working bin 1. The other end of the adjusting plate 46 is provided with an electromagnetic adsorption head 47. The electromagnetic adsorption head 47 is magnetically paired with the top of the cleaning plate 43.

[0052] By starting the sixth motor 45, the sixth motor 45 drives the adjusting screw 44 to rotate, thereby driving the adjusting plate 46 to move. The electromagnetic adsorption head 47 at the lower end of the adjusting plate 46 is magnetically fixed to the cleaning plate 43. Then, by reversing the threaded rod 27, the cleaning plate 43 is driven to move on the filter mesh plate 39, thereby cleaning the polishing debris on the filter mesh plate 39. The cleaned polishing debris is collected by the polishing debris collection bin 38.

[0053] When the polishing device for machining mechanical parts is in use, first, by starting the pushing air cylinder 24, the pushing air 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 assist in supporting the clamping assembly. The clamping assembly is pushed out. At this time, the operator loads the workpiece. The second driving assembly drives the two sets of clamping blocks 13 to move towards each other up and down, and clamps or tensions the workpiece between the up and down directions to clamp and fix one end of the plate-shaped or tubular workpiece. Then, the second motor 16 drives the bidirectional screw 15 to rotate, thereby driving the two sets of moving plates 10 to move towards each other, and then driving the two sets of tensioning jigs to move towards each other, so that the tensioning jigs clamp and fix the other end of the workpiece. Then, the pushing air cylinder 24 drives the clamping assembly to reset. Then, by starting the fourth motor 30, the fourth motor 30 drives the threaded rod 27 to rotate. Through the limitation of the limiting rod 29 on the nut sleeve 28, the nut sleeve 28 moves horizontally, and then drives the polishing head 6 to move horizontally. Cooperating with the air 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, cooperating with the third motor 20 to drive the disc 22 to rotate, the disc 22 synchronously drives the polishing head 6 to rotate through the cooperation of the connecting column 23 and the semi-circular through groove 21, so as to adjust the polishing angle of the polishing head 6, and then perform a comprehensive polishing treatment on the upper surface of the workpiece. When it is necessary to polish the back surface of the workpiece, by starting the first motor 11, the first motor 11 drives the workpiece to flip, so as to polish the back surface of the workpiece.
