It typically consists of components such as fixtures and polishing wheels. After the workpiece is produced, it needs to be polished to improve the surface finish and remove burrs.
[0003] A search revealed a Chinese patent for a surface polishing device for processing cylindrical parts, publication number CN207464843U. The device includes a main body, a support frame, a base on top of the support frame, and the base and support frame are fixedly connected by welding. A working chamber is located above the base.
[0004] The above-mentioned device achieves the adjustability of the device body through the action of the lead screw and slider, thereby grinding workpieces of different lengths. It has a wide range of applications. The cam, in conjunction with the return spring, drives the grinding wheel to move left and right, thereby increasing the working area during polishing, enhancing the polishing effect, improving work efficiency, and making it easy to use.
[0005] However, it is difficult to clean the debris generated in the dust during the polishing process. A large amount of debris may contaminate the surface of the parts during the polishing process, affecting the polishing effect. In addition, only one part can be polished at a time during the polishing process, resulting in low polishing efficiency and affecting production efficiency. Utility Model Content

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example 1
[0024] Combination Figures 1-3 A rod-shaped part production and polishing device includes a worktable 1. A three-jaw chuck 2 is rotatably mounted on one side of the top of the worktable 1 via a support plate. A drive cylinder 3 is mounted on the other side of the top of the worktable 1. A movable plate 4 is mounted on the end of the drive push rod of the drive cylinder 3, and the movable plate 4 is slidably mounted on the top of the worktable 1.
[0025] See Figure 2 Furthermore, a three-jaw chuck 2 5 is rotatably mounted on the side of the movable plate 4 away from the drive cylinder 3. A part body 6 is disposed between the three-jaw chuck 2 5 and the three-jaw chuck 1 2. An adjusting screw 7 is rotatably mounted on the top of the worktable 1 and near the rear of the part body 6. A movable block 8 is threadedly connected to the outer ring of the adjusting screw 7. A polishing block 9 is disposed at the front of the top of the movable block 8. The outer ring of the polishing block 9 fits against the outer ring of the part body 6. An air blowing pipe 16 is movably mounted on the top of the movable plate 4 through a damping support seat. Several air blowing heads are disposed on the outer ring of the air blowing pipe 16. Several adjusting motors 10 are mounted on the side of the worktable 1 near the drive cylinder 3. The drive shaft of each adjusting motor 10 is fixedly connected to one end of the adjusting screw 7.
[0026] Specifically, the part body 6 can be fixed on the three-jaw chuck 12 and three-jaw chuck 25 according to existing technology. When fixing, the clamping length can be adjusted by pushing the movable plate 4 away from or towards the three-jaw chuck 12 through the drive push rod of the drive cylinder 3. After fixing, the outer ring of the part body 6 is in contact with the polishing block 9. At this time, the polishing motor 12 can be started. The rotation of the drive shaft of the polishing motor 12 can drive one of the transmission wheels 11 to rotate. Thus, through the transmission of the transmission belt 13, all three-jaw chucks 12 can be rotated, thereby driving the part body 6 to rotate for polishing. At the same time, the polishing debris generated on the part body 6 will be thrown off as the part body 6 rotates, avoiding its adhesion to the part body 6 and reducing the impact on the polishing effect. At the same time, the air pipe 16 can be connected to the external air supply pipe to continuously spray air towards the part body 6, further reducing the probability of impurity adhesion.
[0027] Example 2
[0028] See Figure 2 and Figure 3 Furthermore, based on Embodiment 1, a transmission wheel 11 adapted to the rotating shaft of the three-jaw chuck 2 is provided on the side of the support plate away from the three-jaw chuck 2. A grinding motor 12 is installed at the front side of the top of the worktable 1, and the drive shaft of the grinding motor 12 is connected to one of the transmission wheels 11. A transmission toothed belt 13 is sleeved on the outer ring of the transmission wheel 11. Several electric telescopic rods 14 are installed on one side of the worktable 1. A tensioning wheel 15 adapted to the transmission toothed belt 13 is installed at the end of the push rod of the electric telescopic rod 14. Several discharge ports adapted to the part body 6 are opened through the upper and lower ends of the worktable 1. A debris collection frame 17 is provided at the lower part of the interior of the worktable 1, and a replacement port adapted to the debris collection frame 17 is provided at the rear of the worktable 1.
[0029] Specifically, most of the debris removed during cleaning will fall into the debris collection box 17 for centralized collection and processing. During the polishing process, by starting the adjusting motor 10, the adjusting screw 7 can be rotated, which in turn pushes the movable block 8 to move, so as to adjust the polishing block 9 during the grinding and polishing process. This provides high flexibility. At the same time, multiple part bodies 6 are fixed on the three-jaw chuck 2, and multiple part bodies 6 can be polished at the same time to improve production efficiency.
[0030] In actual operation, the part body 6 can be fixed on the three-jaw chuck 1 2 and the three-jaw chuck 2 5 according to the existing technology. When fixing, the clamping length can be adjusted by pushing the movable plate 4 away from or closer to the three-jaw chuck 1 2 by the drive push rod of the drive cylinder 3. At the same time, after fixing, the outer ring of the part body 6 is in contact with the polishing block 9. At this time, the grinding motor 12 can be started. The rotation of the drive shaft of the grinding motor 12 can drive one of the transmission wheels 11 to rotate. Thus, through the transmission of the transmission belt 13, all the three-jaw chucks 1 2 can be driven to rotate, thereby driving the part body 6 to rotate for polishing.
[0031] Meanwhile, the debris generated during polishing on the part body 6 will be thrown off as the part body 6 rotates, preventing it from adhering to the part body 6 and reducing the impact on the polishing effect. At the same time, the air pipe 16 can be connected to an external air supply pipe to continuously spray air towards the part body 6, further reducing the probability of impurities adhering.
[0032] Most of the debris removed during cleaning will fall into the debris collection box 17 for centralized collection and processing. During the polishing process, the adjusting motor 10 can be activated to drive the adjusting screw 7 to rotate, thereby pushing the movable block 8 to move. This allows for adjustment of the polishing block 9 during the grinding and polishing process, providing high flexibility. At the same time, multiple part bodies 6 are fixed on the three-jaw chuck 2, allowing multiple part bodies 6 to be polished simultaneously to improve production efficiency.
[0033] Furthermore, the control components and modules used in the aforementioned grinding motor 12, tensioning wheel 15, drive cylinder 3, and adjusting motor 10 are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve improvements to the software and power supply.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
