[0002] Polishing is an important process in machining. Its purpose is to remove burrs, scratches and other defects from the surface of the workpiece and improve the surface quality of the workpiece. For irregularly shaped workpieces, traditional polishing equipment often cannot achieve precise polishing due to their irregular shape, resulting in problems such as low polishing efficiency and poor quality.

For irregularly shaped workpieces, it is necessary to manually adjust the position of the workpiece or polishing wheel, which is cumbersome and the polishing effect is not good, making it difficult to meet production needs. Therefore, an irregularly shaped workpiece polishing device is proposed to solve the above problems. Utility Model Content

[0021] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0022] This application discloses a polishing apparatus for irregularly shaped workpieces. (Refer to...) Figure 1-4 A polishing device for irregularly shaped workpieces includes a processing table 1, a gantry frame 10 mounted on the top outer wall of the processing table 1, a movable seat 11 mounted on the outer wall of the gantry frame 10, a hydraulic cylinder 12 fixedly mounted on the outer wall of the movable seat 11, a drive motor 24 mounted on the output end of the hydraulic cylinder 12 through an angle adjustment mechanism, a polishing wheel 25 fixedly connected to the end of the output shaft of the drive motor 24, and an irregularly shaped clamping mechanism mounted on the top outer wall of the processing table 1, which includes a fixed seat 2, a two-way lead screw 3, clamping blocks 4 and rubber pads 5. The fixed seat 2 is fixedly connected to the top outer wall of the processing table 1, two clamping blocks 4 are symmetrically distributed above the fixed seat 2, two two-way lead screws 3 are rotatably connected to the inner walls on both sides of the fixed seat 2, and the two ends of the clamping blocks 4 are threadedly connected to the two-way lead screws 3 through screw blocks 7. The corresponding outer walls of the two clamping blocks 4 are V-shaped, and the rubber pads 5 are adhered to the outer walls of the clamping blocks 4.

[0023] Two bidirectional lead screws 3 have one end passing through the fixed base 2 and are fixedly connected to a synchronous pulley 8. A synchronous belt 9 is installed on the outer wall of the two synchronous pulleys 8. A servo motor 6 is fixedly installed on the top outer wall of the processing table 1. The servo motor 6 is fixedly connected to one end of one of the bidirectional lead screws 3 away from the synchronous pulley 8. When clamping and fixing irregular workpieces, the servo motor 6 is started. The servo motor 6 drives the bidirectional lead screw 3 connected to it to rotate. Under the transmission action of the synchronous pulley 8 and the synchronous belt 9, the two bidirectional lead screws 3 rotate synchronously. Since the two ends of the clamping block 4 are threadedly connected to the bidirectional lead screw 3 through the screw block 7, and the threads on the bidirectional lead screw 3 are symmetrically distributed, the two clamping blocks 4 can move to the middle or both sides at the same time, thereby realizing the clamping or loosening of irregular workpieces. The corresponding outer wall of the clamping block 4 is V-shaped, which can better adapt to the shape of irregular workpieces and improve the stability of clamping. The rubber pad 5 can prevent the clamping block 4 from damaging the surface of the workpiece.

[0024] The angle adjustment mechanism includes a connecting plate 14, a rotating plate 15, a mounting bracket 19, and a connecting frame 23. The connecting plate 14 is fixedly connected to the output end of the hydraulic cylinder 12. The rotating plate 15 is rotatably connected to the inner wall of the connecting plate 14. The mounting bracket 19 is fixedly connected to the bottom outer wall of the rotating plate 15. The connecting frame 23 is rotatably connected to the bottom middle section outer wall of the mounting bracket 19 via a rotating shaft. The drive motor 24 is fixedly installed on the bottom middle outer wall of the connecting frame 23. The angle adjustment mechanism also includes a bevel gear ring 16, a bevel gear 18, a miniature self-locking motor 17, and a worm gear 21. The bevel gear ring 16 is fixedly connected to the top of the rotating plate 15. A miniature self-locking motor 17 is embedded in the inner wall of the connecting plate 14 on the outer wall of the part. A bevel gear 18 is fixedly connected to the output shaft of the miniature self-locking motor 17. The bevel gear 18 meshes with the bevel gear ring 16. When it is necessary to adjust the angle of the polishing wheel 25 in the horizontal direction, the miniature self-locking motor 17 is started. The miniature self-locking motor 17 drives the bevel gear 18 to rotate. The bevel gear 18 meshes with the bevel gear ring 16, thereby driving the rotating disk 15 to rotate in the connecting plate 14. The rotating disk 15 drives the drive motor 24 and the polishing wheel 25 to rotate through the mounting bracket 19 and the connecting bracket 23, thereby realizing the angle adjustment in the horizontal direction.

[0025] The worm gear 20 is fixedly connected to the outer wall of the rotating shaft inside the mounting frame 19 of the connecting frame 23. The worm 21 is rotatably connected to the inner wall of the mounting frame 19 and meshes with the worm gear 20. A stepper motor 22 is fixedly installed on one side of the outer wall of the mounting frame 19. The end of the output shaft of the stepper motor 22 is fixedly connected to one end of the worm 21. To adjust the angle of the polishing wheel 25 in the vertical direction, the stepper motor 22 is started. The stepper motor 22 drives the worm 21 to rotate. The worm 21 meshes with the worm gear 20, which drives the connecting frame 23 to rotate around the rotating shaft connected to the mounting frame 19. This, in turn, drives the drive motor 24 and the polishing wheel 25 to rotate, thereby achieving the angle adjustment in the vertical direction. Through the setting of the angle adjustment mechanism, the polishing wheel 25 can adapt to the polishing needs of different parts of the irregular workpiece, improving the flexibility and accuracy of polishing.

[0026] A dust collection assembly is installed on the outer wall of the connecting frame 23, including a dust collection hood 26, an annular tube 27, and suction heads 28. The dust collection hood 26 is fixedly connected to the bottom outer wall of the connecting frame 23, and the drive motor 24 is located inside the dust collection hood 26. The annular tube 27 is fixedly installed on the top outer wall of the dust collection hood 26. Multiple suction heads 28 are arranged on the bottom outer wall of the dust collection hood 26 and are all connected to the annular tube 27. A vacuum cleaner 13 is fixedly installed on the outer wall of the movable base 11 on the side opposite to the hydraulic cylinder 12. The suction end is connected to the annular tube 27 through the suction pipe. During the polishing process, a large amount of dust and debris will be generated. When the vacuum cleaner 13 is started, the dust and debris enter the annular tube 27 through the suction head 28, and are then sucked into the vacuum cleaner 13 through the suction pipe, thereby purifying the polishing environment and reducing the impact of dust on the health of operators. At the same time, it can also prevent dust from adhering to the surface of the workpiece and affecting the polishing quality. The dust hood 26 can cover the polishing wheel 25 and the polishing part of the workpiece to improve the dust collection effect.

[0027] Both the gantry 10 and the movable seat 11 can be moved by existing drive devices, thereby driving the polishing mechanism to move in the front-back and left-right directions. The hydraulic cylinder 12 can drive the angle adjustment mechanism, the drive motor 24 and the polishing wheel 25 to move up and down, thereby adjusting the distance between the polishing wheel 25 and the workpiece. When the drive motor 24 is started, it drives the polishing wheel 25 to rotate. With the cooperation of the movable seat 11, the hydraulic cylinder 12 and the angle adjustment mechanism, the polishing wheel 25 can precisely polish various parts of the irregular workpiece.

[0028] The implementation principle of the irregular workpiece polishing device in this application embodiment is as follows: When polishing irregular workpieces, the workpiece is first fixed by placing it on the fixed seat 2. The servo motor 6 is started, and the servo motor 6 drives the bidirectional lead screw 3 connected to it to rotate. Under the transmission action of the synchronous pulley 8 and the synchronous belt 9, the two bidirectional lead screws 3 rotate synchronously. Since the two ends of the clamping block 4 are threadedly connected to the bidirectional lead screw 3 through the screw block 7, and the threads on the bidirectional lead screw 3 are symmetrically distributed, the two clamping blocks 4 will move towards the middle at the same time. Since the corresponding outer wall of the clamping block 4 is V-shaped, it can fit well against the surface of the irregular workpiece. With the rubber pad 5 protecting the surface of the workpiece, the irregular workpiece is stably clamped, preventing the workpiece from shifting during the polishing process.

[0029] After the workpiece is fixed, the polishing position and angle are adjusted. The moving seat 11 can move on the gantry 10, driving the polishing mechanism to move horizontally. The gantry 10 can move back and forth to move the polishing wheel 25 to the approximate horizontal position of the workpiece to be polished area. At the same time, the hydraulic cylinder 12 operates, driving the angle adjustment mechanism, drive motor 24 and polishing wheel 25 to move up and down, adjusting the vertical distance between the polishing wheel 25 and the workpiece, so that it is close to the surface to be polished.

[0030] When it is necessary to adjust the angle of the polishing wheel 25 in the horizontal direction, the micro self-locking motor 17 is started. The micro self-locking motor 17 drives the bevel gear 18 to rotate. The bevel gear 18 meshes with the bevel ring 16 fixed on the top outer wall of the rotating disk 15, thereby driving the rotating disk 15 to rotate in the connecting disk 14. The rotating disk 15 drives the drive motor 24 and the polishing wheel 25 to rotate through the mounting bracket 19 and the connecting bracket 23, so as to realize the adjustment of the angle of the polishing wheel 25 in the horizontal direction to adapt to the polishing requirements of different angles in the horizontal direction of the workpiece.

[0031] To adjust the vertical angle of the polishing wheel 25, start the stepper motor 22. The stepper motor 22 drives the worm gear 21 to rotate. The worm gear 21 meshes with the worm wheel 20 fixed on the outer wall of the shaft of the connecting frame 23, causing the connecting frame 23 to rotate around the shaft connected to the mounting frame 19. This, in turn, drives the drive motor 24 and the polishing wheel 25 to rotate, thereby realizing the vertical angle adjustment of the polishing wheel 25 and meeting the polishing requirements of different angles in the vertical direction of the workpiece.

[0032] After the position and angle are adjusted, the drive motor 24 is started. The drive motor 24 drives the polishing wheel 25 to rotate at high speed to polish the part of the irregular workpiece to be polished. During the polishing process, the vacuum cleaner 13 is started. The dust and debris generated during polishing will be collected by the dust hood 26, enter the annular tube 27 through multiple suction heads 28, and then be sucked into the vacuum cleaner 13 through the air extraction tube to avoid dust affecting the polishing quality and the health of the operator.

[0033] Throughout the polishing process, the gantry 10 moves back and forth, the moving seat 11 moves horizontally, the hydraulic cylinder 12 moves up and down, and the angle adjustment mechanism adjusts at multiple angles. Combined with the high-speed rotation of the polishing wheel 25, comprehensive and precise polishing of all parts of the irregular workpiece can be achieved, and the polishing operation of the irregular workpiece can be completed.
