The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0026] See also Figures 1 to 2 In the first aspect, the present invention provides a tool for grinding the inner surface of automobile air curtain buckle removal pliers, comprising a base 1, a positioning mechanism 2 and a grinding mechanism 3, wherein the positioning mechanism 2 is arranged on one side of the base 1, and the grinding mechanism 3 comprises a rotating table 4, a limiting plate 5, a support rod 6, a drive motor 7 and a grinding head 8; the rotating table 4 is assembled on the side of the base 1 close to the positioning mechanism 2, the limiting plate 5 is fixedly connected to the rotating table 4, and is located on the side of the rotating table 4 away from the base 1, the support rod 6 is assembled on the top of the rotating table 4, the drive motor 7 is fixedly connected to the support rod 6, and is located on the side of the support rod 6 away from the rotating table 4, and the grinding head 8 is assembled at the output end of the drive motor 7.

[0027] In an embodiment of the present invention, the base 1 provides installation conditions for the remaining mechanisms, and the positioning mechanism 2 is used to limit and fix the circlip pliers that need to be polished to prevent the circlip pliers from moving when the polishing mechanism 3 is polishing, thereby affecting the polishing efficiency. When polishing the circlip pliers, the worker first uses his hands to pre-draw the baseline for the circlip pliers, and assembles the circlip pliers to be processed on the positioning mechanism 2. At this time, the worker controls the rotation of the rotating table 4 through the controller and drives the support rod 6 to rotate, thereby bringing the polishing head 8 close to the bending head 23 on one side of the circlip pliers, and drives the polishing head through the drive motor 7. 8 rotates and grinds the bending head 23 to the baseline, stops, controls the rotating table 4 to rotate in the opposite direction, drives the support rod 6 to reverse, and moves the grinding head 8 close to the bending head 23 on the other side of the circlip pliers. The drive motor 7 drives the grinding head 8 again to grind the bending head 23 to the baseline, stops, and finally disassembles the positioning mechanism 2, removes the ground circlip pliers, and completes the grinding process of the removal pliers. The setting of the grinding mechanism 3 can semi-automatically grind the circlip pliers. Compared with the traditional manual grinding method, the grinding is faster and more uniform, the grinding efficiency is better, and the flatness and smoothness of the inner surface of the pliers can be guaranteed. It solves the problem of traditional manual grinding of snap-on removal pliers, which takes a long time to grind and has low grinding efficiency.

[0028] Furthermore, the rotating table 4 includes a rotating motor 9, a reducer 10 and a first bracket 11. The first bracket 11 is fixedly connected to the base 1 and is located on the side of the base 1 close to the positioning mechanism 2. The rotating motor 9 is assembled on one side of the first bracket 11, and the reducer 10 is assembled on one side of the rotating motor 9.

[0029] In an embodiment of the present invention, the first bracket 11 provides an installation location for the rotating motor 9 and the support rod 6. The rotating motor 9 operates, and the output end drives the support rod 6 to rotate on the first bracket 11, thereby driving the grinding head 8 to approach the bending head 23 of the circlip pliers. The reducer 10 is used to decelerate the output end of the rotating motor 9 to prevent the support rod 6 from rotating too fast and failing to smoothly adjust the position of the grinding head 8.

[0030] Furthermore, the limiting plate 5 includes a baffle 12 and a pressure sensor 13 . The baffle 12 is fixedly connected to the first bracket 11 and is located on the top of the first bracket 11 . The pressure sensor 13 is assembled on the side of the baffle 12 close to the support rod 6 .

[0031] In an embodiment of the present invention, the baffle 12 is used to block the rotating support rod 6 and limit the support rod 6. When the support rod 6 is touched, the pressure sensor 13 generates an electrical signal and quickly transmits the electrical signal to the rotating motor 9, thereby stopping the operation of the rotating motor 9. The pressure sensor 13 is a commonly used technology on the market, such as E8Y-A2C-D, E8MS-10 and E8F2-B10C.

[0032] Furthermore, the positioning mechanism 2 includes a second bracket 14, a fixed block 15, a movable clamping block 16 and a fixing bolt 17. The second bracket 14 is fixedly connected to the base 1 and is located at the top of the base 1. The fixed block 15 is fixedly connected to the second bracket 14 and is located at the top of the second bracket 14. The movable clamping block 16 is slidingly connected to the second bracket 14 and is located on one side of the fixed block 15. The fixing bolt 17 is rotatably connected to the fixed block 15 and passes through the movable clamping block 16.

[0033] In an embodiment of the present invention, the second bracket 14 supports the remaining mechanisms of the positioning mechanism 2, and the circlip pliers are clamped and positioned by the movable clamping block 16 and the fixed block 15. Specifically, the worker places the circlip pliers between the fixed block 15 and the movable clamping block 16, and rotates the fixing bolt 17 by hand. The fixing bolt 17 rotates and, under the action of the thread, causes the movable clamping block 16 to approach the circlip pliers, and cooperates with the fixed block 15 to clamp and fix the circlip pliers, thereby achieving the positioning of the circlip pliers.

[0034] Furthermore, the fixing bolt 17 includes a fixing bolt 18 and a rotating head 19. The fixing bolt 18 is rotatably connected to the fixing block 15 and passes through the movable clamping block 16. The rotating head 19 is fixedly connected to the fixing bolt 18 and is located on the side of the fixing bolt 18 away from the fixing block 15.

[0035] In an embodiment of the present invention, by controlling the rotation direction of the fixing bolt 18 on the fixing block 15, the movable clamping block 16 is controlled to approach or move away from the fixing block 15, thereby realizing the disassembly and assembly operation of the circlip pliers. The provision of the rotating head 19 facilitates the worker to rotate the fixing bolt 18, thereby improving practicality.

[0036] See also Figure 3 In a second aspect, the present invention further provides a tool for polishing the inner surface of automobile air curtain buckle removal pliers, which uses the tool for polishing the inner surface of automobile air curtain buckle removal pliers as described in the first aspect, including the following steps:

[0037] S1 obtains a circlip pliers and uses a bending mechanism to bend the front end of the circlip pliers to form a bending head 23;

[0038] S2 assembles the bent circlip pliers on the positioning mechanism 2 to achieve position limiting and fixing of the circlip pliers;

[0039] In an embodiment of the present invention, a worker places the circlip pliers between the fixed block 15 and the movable clamping block 16, and rotates the rotating head 19 by hand to drive the fixing bolt 18 to rotate. Under the action of the thread, the movable clamping block 16 is moved close to the circlip pliers, and cooperates with the fixed block 15 to clamp and fix the circlip pliers, thereby achieving the positioning of the circlip pliers.

[0040] S3 pre-draws the baseline at the bending head 23, the controller controls the rotating table 4 to rotate the grinding head 8 close to the bending head 23 on one side, and drives the grinding head 8 through the driving motor 7 to grind the bending head 23 to the baseline and stop;

[0041] In an embodiment of the present invention, the rotating motor 9 is operated, and the output end drives the support rod 6 to rotate on the first bracket 11, thereby driving the grinding head 8 to approach the bending head 23 of the circlip pliers. When the pressure sensor 13 touches the support rod 6, it generates an electrical signal and quickly transmits the electrical signal to the rotating motor 9, thereby stopping the operation of the rotating motor 9 and completing the adjustment of the position of the grinding head 8. At this time, the drive motor 7 operates to drive the grinding head 8 to grind the bending head 23 until it stops at the baseline.

[0042] S4: The rotating table 4 rotates in the opposite direction to move the grinding head 8 closer to the bending head 23 on the other side, and the driving motor 7 drives the grinding head 8 again to grind the bending head 23 to the baseline and stop;

[0043] S5 disassembles the positioning mechanism 2, removes the polished circlip pliers, and obtains the removal pliers.

[0044] In the embodiment of the present invention, the worker rotates the rotating head 19 in the reverse direction, drives the fixing bolt 18 to rotate in the reverse direction, so that the movable clamping block 16 moves away from the fixed block 15, removes the clamping of the circlip pliers, and then removes the polished circlip pliers, completing the polishing process of the removal pliers.

[0045] See also Figure 4 In a third aspect, the present invention further provides a pair of automobile air curtain buckle removal pliers, which is prepared by grinding the inner surface grinding tool of the automobile air curtain buckle removal pliers as described in the first aspect above, and is characterized in that;

[0046] It includes a pliers body 20, a retaining spring 21 and a rubber sleeve 22.

The pliers body 20 has a bending head 23, and the bending head 23 is located at the front end of the pliers body 20.

[0047] In an embodiment of the present invention, the retaining spring 21 always maintains the accuracy of the relative position of the pliers body 20 during the frequent opening and closing operations of the pliers body 20, ensuring the stability of the overall structure of the pliers body 20. The setting of the rubber sleeve 22 is used to increase the friction between the pliers body 20 and the worker's hand to avoid the worker's hand slipping when using the pliers body 20. The setting of the bending head 23 can enable the pliers body 20 to clamp the air curtain buckle and press the clamping point of the sheet metal inward.
