DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0026] See also Figure 1-Figure 5 , a polishing device for processing a pressure regulating valve, comprising a workbench 1, a clamping assembly and a polishing assembly, wherein the clamping assembly comprises a cover body 2, a first motor 3, a worm wheel 4, a worm 5, a positive and negative threaded screw 6, a centering plate 7, a connecting piece and a clamping plate 8, wherein a processing groove is arranged on the workbench 1, a cover body 2 is arranged on one side of the workbench 1, a worm 5 and two groups of worm wheels 4 are arranged in the cover body 2, two groups of positive and negative threaded screws 6 are rotatably arranged in the processing groove, the positive and negative threaded screws 6 pass through the workbench 1 and the cover body 2 and are connected to the center of the worm wheel 4, the output end of the first motor 3 passes through the cover body 2 and is connected to the worm 5, the centering plate 7 is arranged in two groups symmetrically, the centering plate 7 is provided with screw holes threadedly connected to the positive and negative threaded screws 6, and the centering plate 7 is also provided with a connecting piece connected to the clamping plate 8;

[0027] The first motor 3 is started, and its output end drives the worm 5 to rotate inside the cover 2. Because the worm 5 is meshed with two sets of worm wheels 4, the rotation of the worm 5 will drive the worm wheels 4 to rotate synchronously. The center of the worm wheel 4 is connected to the positive and negative thread screw 6, and when the worm wheel 4 rotates, it will drive the positive and negative thread screw 6 to rotate. Since the centering plate 7 is provided with a screw hole threadedly connected to the positive and negative thread screw 6, according to the principle of thread transmission, the rotation of the positive and negative thread screw 6 will cause the centering plate 7 to move relative to or away from the axial direction of the screw. The centering plate 7 is connected to the splint 8 through a connecting piece. When the centering plate 7 moves, it will drive the splint 8 to move, thereby realizing the limit fixation of pressure regulating valves of different specifications. By controlling the rotation direction and number of turns of the first motor 3, the distance between the splints 8 can be accurately adjusted to accommodate pressure regulating valves of different sizes;

[0028] The second motor 10 is started, and its output end drives the threaded rod 11 to rotate in the chute below the top wall of the bracket 9. Since the slider 12 is threadedly connected to the threaded rod 11, the rotation of the threaded rod 11 will cause the slider 12 to move in the chute along the axial direction of the threaded rod 11. The upper and lower ends of the slider 12 are respectively connected to the lifter 13 and the grinder 14. When the slider 12 moves, the lifter 13 and the grinder 14 will be driven to move together. At the same time, the lifter 13 can control the lifting and lowering of the grinder 14 as needed. By controlling the rotation of the second motor 10 and the lifting and lowering of the lifter 13, the position of the grinder 14 can be flexibly adjusted so that it can accurately grind and polish the shell end face of the pressure regulating valve. During the polishing process, the second motor 10 can accurately control the rotation speed of the threaded rod 11, thereby achieving accurate movement of the grinder 14 and ensuring the accuracy and quality of polishing.

[0029] When installing the splint 8, align the guide block 15 (in a T shape) with the guide groove on the centering plate 7 and insert it. In the movable groove symmetrically arranged on the front and rear sides of the guide block 15, during the insertion of the elastic member (connected with the clamping block 16), the clamping block 16 is squeezed by the wall of the guide groove, overcomes the elastic force of the elastic member and retracts into the movable groove. When the guide block 15 is fully inserted into the guide groove, the clamping block 16 automatically pops out under the elastic force of the elastic member and is clamped into the clamping hole on the guide block 15, thereby achieving a fixed connection between the splint 8 and the centering plate 7. When removing the splint 8, press the clamping block 16 to overcome the elastic force of the elastic member and retract the clamping block 16 into the movable groove. At this time, the clamping block 16 is out of engagement with the clamping hole, and the guide block 15 can be pulled out of the guide groove, thereby removing the splint 8.

[0030] During the polishing process of the pressure regulating valve, the waste chips generated will fall from the end face of the housing of the pressure regulating valve. Since the workbench 1 is provided with a processing groove, the waste chips will fall into the processing groove. The waste chip collection frame 17 is connected to the workbench 1 in a drawer-like sliding manner, and is also connected to the processing groove. The waste chips will enter the waste chip collection frame 17 along the processing groove. When it is necessary to clean the waste chips, the waste chip collection frame 17 can be pulled out from the workbench 1 by pulling the handle 18 on the front of the waste chip collection frame 17, so that the waste chips can be centrally cleaned and transported, keeping the workbench 1 clean and preventing the waste chips from affecting the subsequent loading and fixing operations.

[0031] When the pressure regulating valve is placed for polishing, a part of the pressure regulating valve will be located in the collection groove on the waste collecting frame 17. By rotating the auxiliary plate 21, the auxiliary plate 21 will move up and down along the stud 20 because the screw groove below the auxiliary plate 21 is adapted to the stud 20 on the support column 19, thereby adjusting the height of the auxiliary plate 21. After the auxiliary plate 21 is adjusted to a suitable height, the auxiliary plate 21 can provide additional support for the pressure regulating valve, enhance the stability of the pressure regulating valve during the polishing process, prevent the pressure regulating valve from shaking or shifting during the polishing process, and ensure the smooth progress of the polishing operation and the polishing quality. It should be noted that the top of the stud 20 is lower than the height of the side wall of the waste collecting frame 17. When the waste collecting frame 17 is withdrawn, the auxiliary plate 21 needs to be removed from the stud 20 first. The auxiliary plate 21 will not cause motion interference to the two sets of clamping plates 8 and the centering plate 7, and only plays the role of auxiliary support for the material so that the material can be placed stably.
