[0024] First embodiment

[0025] For example Figures 1-3The utility model provides a mechanical part processing and polishing equipment with fixing function, which comprises a clamping mechanism 100 and a polishing mechanism 200. The clamping mechanism 100 is used for clamping and fixing the mechanical part. The polishing mechanism 200 is used for polishing the surface of the mechanical part. Specifically, the clamping mechanism 100 comprises a first sliding plate 101 and a second sliding plate 102. The second sliding plate 102 is located on the upper end of the first sliding plate 101 and is perpendicular to the first sliding plate 101. A track for the sliding of the second sliding plate 102 is arranged on the first sliding plate 101. The second sliding plate 102 slides along the track. The sliding direction of the second sliding plate 102 is perpendicular to the first sliding plate 101. A first sliding rail 109 is arranged on the upper end of the second sliding plate 102. Two sliding pieces 103 are symmetrically arranged on the first sliding rail 109 and slide thereon. A clamping piece 104 is arranged on each of the two sliding pieces 103. The clamping piece 104 is used for clamping the mechanical part. A hook 106 is arranged on each of the two sliding pieces 103. A spring 105 is arranged on the hook 106. The spring 105 is always in a stretched state. That is, the spring 105 always exerts a pulling force on the two sliding pieces 103. The two clamping pieces 104 are in contact with each other in an initial state. The polishing mechanism 200 comprises a bracket 201. A motor 203 is arranged on the bracket 201. A roller is arranged on the rotating shaft of the motor 203. The roller on the motor 203 is a driving roller. A bogie 205 is arranged on the bracket 201. A roller is arranged on the bogie 205. The roller is a driven roller. A polishing belt 204 is arranged on the rollers. When the motor 203 is started, the rollers drive the polishing belt 204 to rotate. When the polishing belt 204 rotates, the mechanical part is in contact with the polishing belt 204 and is polished. A tray 206 is fixedly arranged on the bracket 201. A second sliding rail 207 is arranged on the upper end of the tray 206. The first sliding plate 101 of the clamping mechanism 100 is arranged on the second sliding rail 207. When the equipment is used, the motor 203 is started to drive the polishing belt 204 to rotate. Then, the two sliding pieces 103 are simultaneously pushed to move leftward and rightward. The two clamping pieces 104 that are in contact with each other are separated. After the two clamping pieces 104 are separated, the mechanical part to be polished is placed between the two clamping pieces 104. Then, the sliding pieces 103 are loosened. At the same time, the two sliding pieces 103 are moved close to each other under the action of the spring 105 until the clamping pieces 104 on the two sliding pieces 103 clamp the mechanical part. Finally, the first sliding plate 101 is pushed to control the mechanical part to move forward and backward, and the second sliding plate 102 is pushed to control the mechanical part to move leftward and rightward until the mechanical part is in contact with the polishing belt 204.

[0026] The spring 105 is arranged to realize the flexible clamping of the clamping piece 104 on the mechanical part. When the worker applies a certain force to push the mechanical part to be in contact with the polishing belt 204, the clamping force of the clamping piece 104 on the mechanical part is constant because the pulling force of the spring 105 is constant. When the pressure between the mechanical part and the polishing belt 204 is too large, the clamping piece 104 cannot stably clamp the mechanical part. The mechanical part is unstable and deviates. The worker is reminded that the pressure is too large, so that the mechanical part is not excessively polished.

[0027] Second embodiment:

[0028] like Figure 2 As shown, the upper end of the second slide plate 102 is provided with a first slide rail 109, and the slide plate 103 is slidably installed on the first slide rail 109. A rotating block 107 is rotatably installed on one side of the first slide rail 109. The rotating block 107 is rectangular or elliptical, with a rotating shaft in the middle. The other end of the rotating shaft is fixed on the first slide rail 109. A handle 108 is provided on the rotating block 107. The left and right sides of the rotating block 107 are in contact with the clamping plates 104. Rotating the handle 108 left and right will drive the rotating block 107 to rotate. Since the length of the central axis of the rotating block is different at different positions, the rotating block 107 will push the two clamping plates 104 to move left and right after rotating. At this time, the mechanical parts are placed between the two clamping plates 104. Finally, the rotating block 107 is reset, and the clamping plates 104 move towards each other to clamp the mechanical parts.

[0029] By setting the rotating plate 107, the sliding plate 103 can be moved left and right. Compared with the method of separating the two sliding plates 103 in the first embodiment, the sliding plate 103 can be moved by turning the handle 108 with one hand, which is more convenient to operate.

[0030] Third embodiment:

[0031] To facilitate the use of different types of clamping plates 104, the clamping plates 104 are bolted to the upper end of the slide plate 103. When clamping mechanical parts of other shapes, the corresponding clamping plates 104 are replaced. In addition, the end of the clamping plate 104 is provided with a chuck, and the inner side of the chuck is provided with a rubber pad. The rubber pad can increase the contact with the mechanical parts on the one hand, and increase the friction with the mechanical parts on the other hand, thereby achieving a more stable clamping effect.

[0032] Fourth embodiment:

[0033] like Figure 3 As shown, the support 201 is also equipped with a telescopic arm 202, and the bogie 205 is installed at the end of the telescopic arm 202. After the telescopic arm 202 is extended, the perimeter of the virtual polygon formed by the rollers installed on the telescopic arm 202 and other rollers on the support 201 becomes larger. A bolt is provided on one side of the telescopic arm 202, and the relative positions of the two sleeve rods of the telescopic arm 202 are fixed by the bolt.

[0034] The tension of the grinding belt 204 mounted on the roller can be adjusted by setting the telescopic arm 202. The taut grinding belt 204 has a more obvious grinding and polishing effect on mechanical parts.

[0035] Fifth embodiment:

[0036] like Figure 3As shown, the bogie 205 is rotatably installed on the telescopic arm 202, an axis is installed on the bogie 205, the other end of the axis is fixed on the end of the telescopic arm 202, the surface of the bogie 205 is provided with a circular arc shaped through hole, a bolt is arranged in the through hole, after the bolt is loosened, the bogie 205 rotates a certain angle around the axis, after the bolt is fastened, the angle of the bogie 205 is fixed.

[0037] By changing the angle of the bogie 205, the direction of the polishing belt 204 on the bogie 205 can be adjusted, so that the polishing direction of the mechanical part is changed.

[0038] The above embodiment is only one of the preferred embodiments of the utility model, and should not be used to limit the protection scope of the utility model, but any insignificant modification or polishing made in the main design idea and spirit of the utility model, the technical problems solved are still consistent with the utility model, and should be included in the protection scope of the utility model.
