[0030] Reference Figures 1 to 3 According to the polishing fixture of the first embodiment of the utility model, it is used to polish a U-shaped workpiece. The polishing fixture includes a bracket 100, a first clamping mechanism and a second clamping mechanism 300. The bracket 100 is provided with a mounting position for mounting a U-shaped workpiece 400. The first clamping mechanism is arranged on the bracket 100. The first clamping mechanism is used to clamp the two ends of the U-shaped workpiece 400. The second clamping mechanism 300 includes a first slide 310 and a clamping drive 320. The first slide 310 is slidably arranged on the bracket 100 and is connected to a first drive 330. The clamping drive 320 is arranged on the first slide 310. The clamping drive 320 is used to clamp the middle position of the U-shaped workpiece 400. The first drive 330 is used to drive the first slide 310 to approach or move away from the mounting position. In this way, by setting the second clamping mechanism 300, the bending deformation of the U-shaped workpiece 400 can be reduced, and the yield rate of the U-shaped workpiece 400 can be improved.

[0031] Specifically, when the U-shaped workpiece 400 is polished, the first clamping mechanism clamps the two ends of the U-shaped workpiece 400, and the first driving member 330 drives the first slide 310 to move in a direction away from the installation position, so that the clamping driving member 320 can clamp the middle position of the U-shaped workpiece 400. When the polishing assembly polishes the middle position of the U-shaped workpiece 400, the clamping driving member 320 can provide support force for the U-shaped workpiece 400 to reduce the bending deformation of the U-shaped workpiece 400, thereby improving the yield rate of the U-shaped workpiece 400.

[0032] It should be pointed out that there are two clamping drive members 320, which are arranged side by side and spaced apart. When the polishing assembly polishes the position of the U-shaped workpiece 400 clamped by the clamping drive member 320, the corresponding clamping drive member 320 releases the U-shaped workpiece 400, so that the outer surface of the U-shaped workpiece 400 can be completely polished, which is not described in detail here.

[0033] It should be noted that the U-shaped workpiece 400 may be a metal component such as a door handle, and is not limited here.

[0034] In some embodiments of the present invention, the first clamping mechanism includes a first clamping member 210 and a second clamping member 220, and the first clamping member 210 and the second clamping member 220 can be slidably disposed on the bracket 100, the first clamping member 210 is connected to the second driving member 230, and the second clamping member 220 is connected to the third driving member 240, the second driving member 230 is used to drive the first clamping member 210 to abut against one end of the U-shaped workpiece 400, and the third driving member 240 is used to drive the second clamping member 220 to abut against the other end of the U-shaped workpiece 400, so as to stably fix the U-shaped workpiece 400.

[0035] Specifically, when fixing the two ends of the U-shaped workpiece 400, the second driving member 230 drives the first clamping member 210 to move so that the first clamping member 210 abuts against the inner side surface of one end of the U-shaped workpiece 400, and the third driving member 240 drives the second clamping member 220 to move so that the second clamping member 220 abuts against the inner side surface of the other end of the U-shaped workpiece 400, thereby stably fixing the U-shaped workpiece 400.

[0036] It should be noted that the first driving member 330 is located between the second driving member 230 and the third driving member 240, so that the structure of the polishing fixture is compact and the overall volume of the polishing fixture can be reduced to facilitate the manipulator to drive the polishing fixture to move, which will not be described in detail here.

[0037] In some embodiments of the utility model, the first clamping mechanism also includes a first lever 250, and the first clamping member 210 is connected to the output end of the second driving member 230 through the first lever 250.

The second hinged end is hinged to the bracket 100, the first hinged end is hinged to the output end of the second driving member 230, and the third hinged end is hinged to the first clamping member 210. The distance between the first hinged end and the second hinged end is greater than the distance between the third hinged end and the second hinged end. In this way, the output force of the second driving member 230 can be amplified to increase the clamping force of the first clamping member 210 and the second clamping member 220, and the clamping stability of the first clamping mechanism can be improved.

[0038] Specifically, the second hinged end is arranged at the middle position of the first lever 250, the first hinged end is arranged at one end of the length direction of the first lever 250, and the third hinged end is arranged at the other end of the length direction of the first lever 250. Since the distance between the first hinged end and the second hinged end is greater than the distance between the third hinged end and the second hinged end, the output force of the second driving member 230 can be amplified to increase the clamping force of the first clamping member 210 and the second clamping member 220, thereby improving the clamping stability of the first clamping mechanism.

[0039] The first clamping mechanism also includes a second lever 260, and the second clamping member 220 is connected to the output end of the third driving member 240 through the second lever 260. The second lever 260 has a fourth hinged end, a fifth hinged end and a sixth hinged end arranged side by side and spaced apart. The fifth hinged end is hinged to the bracket 100, the fourth hinged end is hinged to the output end of the third driving member 240, and the sixth hinged end is hinged to the second clamping member 220. The distance between the fourth hinged end and the fifth hinged end is greater than the distance between the sixth hinged end and the fifth hinged end. In this way, the output force of the third driving member 240 can be amplified to increase the clamping force of the first clamping member 210 and the second clamping member 220, and the clamping stability of the first clamping mechanism can be improved. Specifically, the fifth hinged end is arranged at the middle position of the first lever 250, the fourth hinged end is arranged at one end of the length direction of the second lever 260, and the sixth hinged end is arranged at the other end of the length direction of the second lever 260. Since the distance between the fourth hinged end and the fifth hinged end is greater than the distance between the sixth hinged end and the fifth hinged end, the output force of the second driving member 230 can be amplified to increase the clamping force of the first clamping member 210 and the second clamping member 220, thereby improving the clamping stability of the first clamping mechanism.

[0040] Of course, in some specific embodiments, the output end of the second driving member 230 may also be directly connected to the first clamping member 210, and the output end of the third driving member 240 may also be directly connected to the second clamping member 220, which is not limited here.

[0041] In some embodiments of the utility model, the first clamping member 210 is provided with a first hinge hole 211 and a second hinge hole 212, and the first hinge hole 211 and the second hinge hole 212 are spaced apart along the length direction of the first clamping member 210. The first hinge hole 211 or the second hinge hole 212 is hingedly matched with the third hinge end, and can adapt to U-shaped workpieces 400 of different lengths to improve the versatility of the polishing fixture.

[0042] Specifically, the first hinge hole 211 or the second hinge hole 212 is hingedly matched with the third hinge end through the hinge axis, and the first hinge hole 211 is located between the second hinge end and the second hinge hole 212. When the length of the U-shaped workpiece 400 is shorter, the first hinge hole 211 is hingedly matched with the third hinge end. When the length of the U-shaped workpiece 400 is longer, the second hinge hole 212 is hingedly matched with the third hinge end. It can adapt to U-shaped workpieces 400 of different lengths to improve the versatility of the polishing fixture.

[0043] Of course, in some specific implementations, the first clamping member 210 may also be provided with a third hinge hole or a fourth hinge hole, etc., which is not limited here.

[0044] In some embodiments of the present invention, a first guiding structure is provided between the first clamping member 210 and the bracket 100 to guide the first clamping member 210 so that the first clamping member 210 can stably abut against one end of the U-shaped workpiece 400 .

[0046] Specifically, along the length direction perpendicular to the first guide channel, the cross-section of the first guide channel matches the cross-section of the first clamping member 210, and the first clamping member 210 can abut against the side wall of the first guide channel, and can guide the first clamping member 210 so that the first clamping member 210 can stably abut against one end of the U-shaped workpiece 400.

[0047] It should be noted that the first guide structure may also be a structure in which a guide hole and a guide pin cooperate, which will not be described in detail here.

[0048] In some embodiments of the utility model, a second guide structure is provided between the second clamping member 220 and the bracket 100, which can guide the second clamping member 220 so that the second clamping member 220 can stably abut against one end of the U-shaped workpiece 400.
