Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] As shown in the figure, a motor housing inner hole polishing device includes a frame 1, on which a polishing mechanism 2 and a clamping mechanism 3 are arranged, and the polishing mechanism 2 includes a sliding frame 21, a rotating shaft 22, an adjusting block 23, an adjusting sleeve 24 and a polishing block 25. The sliding frame 21 can be horizontally slidably arranged on the frame 1 and is transmission-connected to a first motor 12 arranged on the frame 1, and the rotating shaft 22 is rotationally arranged on the sliding frame 21 and is transmission-connected to a second motor 26 arranged on the sliding frame 21. A plurality of the adjusting blocks 23 are distributed around the rotating shaft 22, and a first adjusting rod 231 and a second adjusting rod 232 are hinged on the adjusting block 23, the other end of the first adjusting rod 231 is hinged on the rotating shaft 22, the adjusting sleeve 24 is sleeved on the rotating shaft 22, the other end of the second adjusting rod 232 is hinged on the adjusting sleeve 24, and the polishing block 25 is arranged on the adjusting block 23.

[0024] Specifically, the sliding frame 21 is slidably arranged on the frame 1 and is transmission-connected to the first motor 12: the frame 1 is provided with a first linear slide rail 11, the sliding frame 21 is fixedly connected to the sliding seat of the first linear slide rail 11, a transmission screw rod 13 transmission-connected to the first motor 12 is rotatably arranged on the frame 1, and a transmission seat screwed on the transmission screw rod 13 is fixedly connected to the sliding frame 21.

[0025] Specifically, the clamping mechanism 3 includes a clamping frame 31, and the two clamping frames 31 can be horizontally slidably arranged on the frame 1 and are symmetrically distributed on both sides of the moving path of the rotating shaft 22. Specifically, the frame 1 is provided with a second linear slide rail 14 that is perpendicular to the first linear slide rail 11, and the clamping frame 31 is fixedly connected to the sliding seat of the second linear slide rail 14. The clamping frame 31 is provided with a V-shaped clamping groove 311, and the frame 1 is provided with two output shafts respectively fixedly connected to the two clamping frames 31. Clamping cylinders 32.

[0026] Specifically, the interior of the rotating shaft 22 is hollow to form a movable cavity 221, and the rotating shaft 22 is provided with a plurality of adjustment grooves 222 along the length direction of the rotating shaft 22 and connected to the movable cavity 221. The inner wall of the adjusting sleeve 24 is fixedly connected with a plurality of connecting rods 241 that pass through the adjustment grooves 222 and extend into the movable cavity 221. The end of the connecting rod 241 extending into the movable cavity 221 is fixedly connected with a transmission block 242 located in the movable cavity 221. An adjusting screw 27 that is screwed into the transmission block 242 and has one end extending out of the movable cavity 221 is rotatably arranged in the movable cavity 221.

[0027] In the above embodiment, the motor shell to be polished is placed between the two clamping frames 31, and the two clamping cylinders 32 respectively drive the two clamping frames 31 to slide toward each other on the second linear slide rail 14, and the motor shell is clamped in the clamping groove 311 of the two clamping frames 31. When the V-shaped clamping groove 311 clamps the motor shell, since the motor shell is cylindrical, the axis of the motor shell is aligned with the rotating shaft 22 while clamping the motor shell, so that the motor shell is clamped and fixed, and then the transmission fast is driven to move in the moving cavity 221 by rotating the adjusting screw 27, and then the adjusting sleeve 24 is driven to slide on the rotating shaft 22 by moving the connecting rod 241 in the adjusting groove 222, and the sliding of the adjusting sleeve 24 drives the second adjusting rod 232 to move, and under the action of the connecting rod mechanism composed of the second adjusting rod 232 and the first adjusting rod 231, a plurality of adjusting rods are synchronously driven. The block 23 and the polishing block 25 move, and the distance between the polishing block 25 and the rotating shaft 22 is adjusted, so as to adjust the size of the arc formed by the outermost moving path of the polishing blocks 25, so that the size of the arc formed by the outermost moving path of the polishing blocks 25 matches the inner hole size of the motor housing. Then the second motor 26 drives the rotating shaft 22 to rotate, thereby driving the polishing blocks 25 to rotate synchronously. At the same time, the first motor 12 drives the rotating screw to rotate and drives the sliding seat to move toward the motor housing through the transmission seat, so that the rotating polishing block 25 gradually extends into the inner hole of the motor housing to polish the inner hole of the motor housing. Through the above method, the polishing mechanism 2 can be applied to the polishing processing of motor housings with different inner hole sizes without replacing the polishing block 25. The operation process is very simple, which makes the polishing mechanism 2 have better applicability and reduces the production cost.

[0028] Preferably, the end of the adjusting screw rod 27 passing through the moving cavity 221 is fixedly connected with a cylindrical operating block 271, and a hexagonal hole is provided on the end surface of the operating block 271. A fixing ring 223 that contacts the side of the operating block 271 is fixedly connected to the end surface of the rotating shaft 22, and a clamping ring 224 is rotatably connected to the end surface of the rotating shaft 22. A clamping bolt 225 that is screwed on the fixing ring 223 is passed through the clamping ring 224, and the clamping ring 224 is tightly pressed against the side of the operating block 271 under the action of the clamping bolt 225. On the upper part, the hexagonal wrench is inserted into the hexagonal hole on the operating block 271 to rotate the adjusting screw 27, thereby facilitating the operation of adjusting the distance between the polishing block 25 and the rotating shaft 22. After the adjustment is in place, the clamping nut is tightened to make the clamping ring 224 tightly against the operating block 271 and cooperate with the fixing ring 223 to clamp and fix the operating block 271 to prevent the adjusting screw 27 from rotating during the polishing process, so that the polishing block 25 can be stably maintained in the adjusted position during the polishing process, thereby ensuring the polishing effect.

The structure in which the polishing block 25 is installed on the adjusting block 23, after unscrewing the mounting bolt 234 and removing the mounting plate 235, the mounting plate 235 is installed. Block 281 can be taken out from the installation groove 233 to conveniently install the polishing block 25. Conversely, the polishing block 25 can also be conveniently installed, which is convenient for replacing the polishing block 25 after the polishing block 25 is worn. The purpose of installing multiple polishing blocks 25 on the adjusting block 23 is that when the polishing mechanism 2 polishes the motor housing with different inner hole sizes, the polishing blocks 25 at different positions contact the inner hole wall of the motor housing to perform the polishing operation. Therefore, the polishing block 25 with greater wear can be replaced separately, without the need to replace all the polishing blocks 25 on the same adjusting block 23 as a whole, thereby reducing the production cost.

[0030] Preferably, two first adjusting rods 231 are symmetrically arranged on the adjusting block 23, so that the first adjusting rods 231 can provide a more stable support for the adjusting block 23, thereby ensuring the stability of the polishing block 25 during the polishing operation, and further ensuring the polishing effect.

[0031] Preferably, a rubber pad 312 is provided on the clamping groove 311 to enhance the stability of the clamping frame 31 when clamping and fixing the motor housing, thereby ensuring the polishing effect.
