[0024] like Figures 1 to 3 As shown, a flexible positioning device for a spoke plate ring comprises a mounting frame 1, on which a gear 1 2 and a gear 2 3 meshing with each other are arranged, the gear 1 2 is rotatably connected to the inner wall surface of the mounting frame 1, a motor 4 for driving the gear 1 2 to rotate is arranged on the outer side of the mounting frame 1, a through hole for the output end of the motor 4 to pass through is provided on the mounting frame 1, "L"-shaped positioning columns 6 for fixing the spoke plate ring are provided on both sides of the mounting frame 1, a rotating moving part 5 for changing the distance between the two positioning columns 6 is provided on the gear 2 3, a placement cavity 7 is provided on the wall surface of the positioning column 6 facing the spoke plate ring, a buffer part 8 for improving the stability of clamping the spoke plate ring is provided inside the placement cavity 7, and a stabilizing part 9 for enhancing the stability of the positioning column 6 when moving is installed at the bottom of the mounting frame 1;

[0025] Specifically, by driving gear 1 2, gear 2 3 can be driven to rotate, and under the cooperation of the rotating and moving part 5, the two positioning posts 6 can be driven to approach each other. The arranged positioning posts 6 can clamp and fix the spoke plate ring to be ground, thereby ensuring the stability and firmness of the spoke plate ring during the grinding operation, eliminating the trouble of workers fixing the spoke plate ring, and also improving the safety factor during the grinding operation of the spoke plate ring; the arranged buffer part 8 can not only enhance the fixing effect of the spoke plate ring, but also shrink and change accordingly during clamping, thereby achieving the effect of flexible positioning; at the same time, in cooperation with the rotating and moving part 5, spoke plate rings of different sizes can also be clamped and fixed, thereby enhancing the practicality of the device.

[0026] like Figure 2 As shown, the rotating moving part 5 includes a rotating column 502, and the rotating columns 502 are fixedly installed on the left and right side walls of the gear 2 3, and a rotating cavity 501 for rotating the rotating column 502 is opened on the mounting frame 1, and a screw 503 whose outer wall surface is threadedly connected to the positioning column 6 is fixedly installed on the movable end of the rotating column 502, and the positioning column 6 is threadedly sleeved on the outer wall surface of the screw 503;

[0027] Specifically, the rotating column 502 is arranged to rotate inside the rotating chamber 501 during the rotation of the gear 2 3, thereby driving the two screws 503 to rotate synchronously, and achieving the purpose of driving the two positioning columns 6 to move closer to or away from each other, so as to clamp and fix spoke plate rings of different sizes, thereby improving the stability of the spoke plate ring during grinding operations and the practicality of the device. Compared with manual fixation, it not only reduces the burden on workers, but also effectively improves processing efficiency.

[0028] like Figure 2 As shown, the movable end of each screw rod 503 is bonded with an interception block 504;

[0029] Specifically, the interception block 504 can intercept and limit the outer side of the positioning column 6 to prevent the positioning column 6 from being accidentally rotated out of the screw rod 503 due to excessive rotation of the gear 2 3 .

[0030] like Figure 2 As shown, the outer wall surface of the mounting frame 1 is provided with a receiving cavity 505, and the side wall surface of the positioning column 6 and the inner wall surface of the receiving cavity 505 are provided with a telescopic column 506;

[0031] Specifically, the telescopic column 506 can enhance the stability of the positioning column 6 during movement, prevent the positioning column 6 from shaking or even tilting, and ensure the stability and stability of the spoke plate ring during grinding operation.

[0032] like Figure 3As shown, the buffer part 8 includes a cushion block 801, and a plurality of cushion blocks 801 are arranged on the outside of each placement cavity 7, a damping spring 802 and a telescopic rod 803 are arranged between the side wall surface of the cushion block 801 and the inner wall surface of the placement cavity 7, and a convex block 804 made of flexible plastic or soft rubber material is bonded to the outer wall surface of the cushion block 801;

[0033] Specifically, the protrusion 804 is arranged to be in contact with the outer surface of the spoke plate ring. The protrusion 804 made of flexible plastic or soft rubber material can not only increase the contact area with the spoke plate ring, increase the clamping surface, and ensure the stability of clamping, but also protect the outer surface of the spoke plate ring to avoid wear of the spoke plate ring due to excessive clamping force. At the same time, in the process of the two positioning columns 6 gradually approaching, the damping spring 802 and the telescopic rod 803 can shrink accordingly, thereby enhancing the stability of clamping the spoke plate ring.

[0034] like Figure 3 As shown, an electric turntable 805 for driving a plurality of cushion blocks 801 to rotate is installed on the inner wall surface of the placement cavity 7;

[0035] Specifically, the electric turntable 805 can drive the clamped spoke plate ring to rotate during grinding, so that the placement of the spoke plate ring can be adjusted, so that all surfaces of the spoke plate ring can be grinded, ensuring the integrity of the grinding and avoiding any missing position.

[0036] like Figure 1 As shown, the stable portion 9 includes a base 901, the base 901 is fixedly installed at the bottom of the mounting frame 1, the bottoms of the two positioning columns 6 are mortised with sliding bottom blocks 902, and the upper surface of the base 901 is provided with a slide rail 903 for the sliding bottom blocks 902 to slide;

[0037] Specifically, the sliding bottom block 902 can move along the laying direction of the slide rail 903 when the positioning column 6 moves, thereby ensuring the stability and firmness of the bottom of the positioning column 6 when it moves horizontally.

[0038] When in use, the operator first places the spoke plate ring to be polished between the two positioning posts 6, and then drives the motor 4 to drive the gear 1 2 to rotate. Under the rotation cooperation of the rotating moving part 5, the gear 2 3 can drive the screw 503 to rotate, so that the two positioning posts 6 threadedly connected to the screw 503 can approach each other to clamp and fix the spoke plate ring. In the process of the two positioning posts 6 gradually approaching each other, the damping spring 802 and the telescopic rod 803 can shrink and change under the squeezing force, thereby improving the clamping effect of the spoke plate ring, and at the same time, the convex block 804 of the flexible plastic or soft rubber material will also shrink. The extrusion deformation occurs accordingly, which can not only increase the contact area with the spoke plate ring, but also improve the clamping firmness. After the installation is completed, the device can be placed under the grinding tool (in actual use, a universal wheel with brake is installed at the bottom of the mounting frame 1), so that the spoke plate ring can correspond to the grinding tool, and then the grinding tool can be started. During the grinding process, the electric turntable 805 can be driven to drive the clamped spoke plate ring to rotate, thereby ensuring the adequacy of the grinding and avoiding grinding omissions in a certain direction. After the grinding is completed, the reverse drive gear 2 can drive the two positioning columns 6 to move away from each other so as to remove the spoke plate ring.

[0039] In summary: by driving gear 1 2, gear 2 3 can be driven to rotate, and under the cooperation of the rotating and moving part 5, the two positioning columns 6 can be driven to approach each other, and the arranged positioning columns 6 can clamp and fix the spoke plate ring to be ground, thereby ensuring the stability and firmness of the spoke plate ring during the grinding operation, eliminating the trouble of workers fixing the spoke plate ring, and also improving the safety factor during the grinding operation of the spoke plate ring; the arranged buffer part 8 can not only enhance the fixing effect of the spoke plate ring, but also shrink and change accordingly during clamping, thereby achieving the effect of flexible positioning, and at the same time, in cooperation with the rotating and moving part 5, spoke plate rings of different sizes can also be clamped and fixed, thereby enhancing the practicality of the device.
