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 scope of protection of the present utility model.

[0022] Specific implementation examples are given below.

[0023] Please see Figure 1-5 As shown, an inner wall grinding device for automotive pipe fittings includes a worktable 11, with a motor 12 fixedly connected to the top of the worktable 11; a grinding shaft 13 is installed at the output end of the motor 12, and a groove 14 is provided on the grinding shaft 13. Multiple supports 15 are slidably connected inside the groove 14, and grinding blocks 16 are installed on the supports 15. A movable seat 22 is provided in the middle of the groove 14, and a connecting rod 23 is hinged to the surface of the movable seat 22 at a position corresponding to the support 15. One end of the connecting rod 23 away from the movable seat 22 is hinged to the support 15. An adjustment assembly is provided in the middle of the groove 14; the adjustment assembly includes an adjustment screw 21, and a threaded sleeve is fixedly connected to the middle of the movable seat 22. The adjustment screw 21 passes through the threaded sleeve and is threadedly connected to it.

[0024] In use, the grinding block 16 is installed on the support 15, which can slide in the groove 14. Then, by rotating the adjusting screw 21, the thread action of the adjusting screw 21 and the screw sleeve drives the moving seat 22 to move. The moving seat 22 and the support 15 are hinged to a connecting rod 23. Under the action of the connecting rod 23, the grinding block 16 is pushed to move, so that the grinding block 16 extends out. This can improve the fit of the inner diameter of the pipe fitting, thereby increasing the scope of application and facilitating the work.

[0025] Furthermore, such as Figure 1-5As shown, a slot is provided in the middle of the support 15, and the grinding block 16 is slidably connected inside the slot. A retainer 31 is slidably connected to the end of the support 15. The retainer 31 and the support 15 are detachably connected by bolts 32. A slot is provided on the grinding block 16 at the position corresponding to the retainer 31. A worm gear 41 is fixedly connected to the end of the adjusting screw 21, and a worm 42 is rotatably connected to the end of the grinding shaft 13. The worm 42 and the worm gear 41 mesh with each other.

[0026] In use, the grinding block 16 is inserted into the slot of the support 15, the retainer 31 is inserted into the side end of the slot, and then the end of the support 15 is tightened by the bolt 32. After that, the retainer 31 is inserted into the slot of the grinding block 16 to fix the grinding block 16. Due to the above-mentioned detachable structure, it is convenient for the staff to replace it. Due to the worm gear 41 and worm 42, it is convenient to rotate and drive the adjusting screw 21 to move.

[0027] Furthermore, such as Figure 1-5 As shown, a fixing block 51 is fixedly connected to the inner side wall of the end of the grinding shaft 13, a fixing screw 54 is fixedly connected to the side of the fixing block 51, a fixing seat 52 is sleeved on the fixing screw 54, and a threaded seat 53 is threadedly connected to the fixing screw 54.

[0028] In use, the end of the grinding shaft 13 is fixedly connected to the fixing screw 54 by the fixing block 51, the fixing seat 52 is inserted into the end of the slide groove 14 and tightened by the threaded seat 53, and the fixing seat 52 is locked at the end of the support 15 to fix the end of the support 15, thereby improving the stability of the support 15.

[0029] Furthermore, such as Figure 1-5 As shown, an electric cylinder 61 is fixedly connected to the workbench 11, and a connecting seat 62 is fixedly connected to the output end of the electric cylinder 61. A clamp capable of fixing the pipe fitting is installed on the top of the connecting seat 62.

[0030] When in use, the pipe fitting is fixed above the connecting seat 62 by a clamp, and the connecting seat 62 is moved by the electric cylinder 61, thereby moving the pipe fitting. Therefore, the grinding block 16 can easily grind the pipe fitting, making it convenient for workers to use.

[0031] Furthermore, such as Figure 1-5 As shown, the adjustment assembly also includes a pneumatic actuator capable of moving the movable seat 22.

[0032] Working principle: During use, the grinding block 16 is installed on the support 15, which can slide within the groove 14. Rotating the adjusting screw 21 causes the moving seat 22 to move due to the thread action of the screw 21 and the threaded sleeve. A connecting rod 23 is hinged between the moving seat 22 and the support 15. The connecting rod 23 then pushes the grinding block 16 to extend, improving its fit to the inner diameter of the pipe fitting and thus broadening its applicability and facilitating use. In use, the grinding block 16 is inserted into the slot of the support 15, and the retaining seat 31 is inserted into the side of the slot. The end of the support 15 is then secured with bolts 32. The retaining seat 31 is then inserted into the slot of the grinding block 16, allowing grinding to proceed. Block 16 is fixed, and the aforementioned detachable structure allows for easy replacement by workers. The worm gear 41 and worm 42 facilitate rotation to drive the adjusting screw 21. During use, the end of the grinding shaft 13 is fixedly connected to the fixing screw 54 via the fixing block 51. The fixing seat 52 is inserted into the end of the slide groove 14 and secured by the threaded seat 53. The fixing seat 52 is locked onto the end of the support 15, thus fixing the end of the support 15 and improving its stability. During use, the pipe is fixed above the connecting seat 62 by a clamp, and the connecting seat 62 is moved by the electric cylinder 61, thereby moving the pipe. This allows the grinding block 16 to easily grind the pipe, making it convenient for workers to use.
