DETAILED DESCRIPTION

[0023] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0024] The specific embodiment of the utility model provides a rotor inner cavity grinding tool, combined with the attached Figure 2 and attached Figure 3 As shown, it mainly includes a mounting base 1, a placement plate 2, a positioning component 3 and a grinding component 4.

[0025] Among them, the placing disc 2 is rotatably arranged on the mounting seat 1, and the placing disc 2 and the mounting seat 1 are coaxially arranged, so that the placing disc 2 can rotate on the mounting seat 1, and then can drive the workpiece to rotate, and can adjust the direction of the workpiece to ensure that all holes and grooves on the workpiece can be ground. For this purpose, a placing position 5 for placing the workpiece is provided on the placing disc 2. The workpiece is placed on the placing position 5. A positioning component 3 is provided between the placing disc 2 and the mounting seat 1. The positioning component 3 is used to position the placing disc 2 to a preset position to limit the random rotation of the placing disc 2 in turn. Grinding can be performed at this preset position. The positioning component The number of 3 is the same as the number of slots on the workpiece. The positioning components 3 are evenly distributed along the circumference of the shaft, and the slots on the workpiece are also distributed along the circumference of the workpiece. This design allows each slot to be positioned when grinding the alignment grinding component 4. The grinding component 4 is arranged on one side of the mounting seat 1. The grinding head 18 of the grinding component 4 can slide toward and away from the workpiece. After the placement disk 2 is rotated to a certain position, the grinding process can be performed by the grinding head 18. After the grinding head 18 is withdrawn from the slot, the placement disk 2 can be rotated to the next slot position to grind the next slot. The present application adopts this rotor inner cavity grinding tool for grinding the rotor workpiece, improving the processing efficiency. In addition, the placement disk 2 can reduce the labor intensity of workers and save labor costs by placing the workpiece.

[0026] In the specific embodiments of this application, Figure 2 and attached Figure 4 , wherein the positioning assembly 3 includes a positioning spring 6 and a positioning bead 7 provided on the placement plate 2, and a positioning groove 8 provided on the mounting seat 1. Specifically, a mounting hole is provided on the plate body of the placement plate 2 close to the end face of the mounting seat 1, and the positioning spring 6 is provided in the mounting hole. The positioning bead 7 is provided at one end of the positioning spring 6 facing the mounting seat 1. This positioning spring 6 is in a compressed state. At this time, the positioning bead 7 is against the end face of the mounting seat 1, and the positioning bead 7 can enter the positioning groove 8. When the positioning bead 7 enters the positioning groove 8, it is in a positioned state. The positioning bead 7 can be disengaged from the positioning groove 8 by rotating the placement plate 2. The placement plate 2 is continued to be rotated until all the positioning beads 7 enter the positioning groove 8 again for positioning. The spring can extend and compress when the positioning bead 7 enters or disengages from the positioning groove 8. It should be noted that the depth of the positioning groove 8 is relatively shallow to ensure that the positioning bead 7 can be disengaged from the positioning groove 8.

[0027] In some embodiments, the mounting base 1 includes a workbench 9 and a height adjustment screw 10 . The workbench 9 is set on a work frame 11 through the height adjustment screw 10 , and the placement plate 2 is set on the workbench 9 .

[0028] The workbench 9 is a plate-like structure. The bottom of the height adjustment screw 10 is hingedly connected to the work frame 11. The middle portion of the height adjustment screw 10 has external threads that are threadedly connected to the workbench 9. Turning the height adjustment screw 10 allows the height of the workbench 9 to be adjusted. This height adjustment screw 10 indirectly adjusts the height of the placement plate 2 mounted thereon, indirectly adjusting the height of the workpiece, thereby ensuring that the workpiece faces the grinding assembly 4 and ensuring optimal grinding results.

[0029] In some embodiments, there are multiple height adjustment screws 10 and they are arranged on the peripheral side of the placement plate 2. The workbench 9 can be a rectangular plate, preferably a square plate. The number of height adjustment screws 10 can be 4, which are respectively arranged at the four corners of the workbench 9, so as to ensure the stability of the workbench 9.

[0030] In some embodiments, the Figure 2 、 3 As shown in Figure 5, the placement plate 2 includes a rotating base 12, a fixed pressure cover 13, a crank 14, a spring 15, and a fixing screw 16. The rotating base 12 is set on the mounting base 1, and the fixing screw 16 passes through the spring 15 and the light hole of the mounting base 1 in turn and is threadedly connected to the rotating base 12. At this time, the fixing screw 16 can be used as the rotating axis of the mounting base 1 and the rotating base 12. One end of the spring 15 is against the nut end of the fixing screw 16, and the other end is against the mounting base 1. This arrangement can not only realize the connection between the mounting base 1 and the rotating base 12, but also prevent the fixing screw 16 from being directly unlocked and locked with the mounting base 1 through the spring 15, thereby ensuring that the rotating base 12 can rotate smoothly. The fixed pressure cover 13 is detachably connected to the rotating base 12. In practice, it is necessary to place the workpiece on the rotating base 12, and then place the fixed pressure cover 13 on the workpiece, and then connect the fixed pressure cover 13 to the rotating base 12. A placement position 5 is formed between the fixed pressure cover 13 and the rotating base 12. This installation position is used to fix the workpiece. The crank 14 is set on the fixed pressure cover 13, specifically on the end face of the fixed pressure cover 13 away from the rotating base 12, that is, on the top of the fixed pressure cover 13. The crank 14 is convenient for workers to grasp and perform rotation operations.

[0031] In some embodiments, the rotating base 12 and the fixed pressure cover 13 are connected by bolts 17. The bolt connection method is reliable and convenient for disassembly and assembly.

[0032] In some embodiments, the grinding assembly 4 includes a grinding head 18, a grinding head fixing seat 19, a slider 20 and a slide rail 21. The grinding head 18 is set on the slider 20 through the grinding head fixing seat 19. The slider 20 is slidingly connected to the slide rail 21. The sliding connection between the slide rail 21 and the slider 20 enables the grinding head 18 to translate, and this translation can be translated toward the workpiece or away from the workpiece. When translating toward the workpiece, the workpiece can be ground and processed. After translating away from the workpiece, the grinding assembly 4 will not affect the rotation adjustment position of the workpiece. The axis of the slide rail 21 intersects with the axis of the rotating shaft of the mounting seat 1, so that the grinding head 18 can face the slot hole on the workpiece.
