Description

Technical Field

[0001] The invention relates to the field of clamps, and in particular to a positioning device for drilling a wheel hub decorative cover. Background Art

[0002] With the advancement of modern industry, cars have become an indispensable tool for daily travel, production, and transportation. With the improvement of aesthetic standards, various decorative accessories on cars have also begun to develop rapidly, especially car wheel roller covers, which can effectively protect and decorate the wheel hub. The wheel hub processing and production process requires injection molding, perforation printing, and other processes, among which drilling is a very important process. The purpose of drilling is to drill threaded holes in the cover to facilitate the subsequent assembly of the wheel hub and the cover.

DETAILED DESCRIPTION

[0021] The technical solution of the present invention will be further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0022] A positioning device for drilling a wheel hub decorative cover comprises a base 1:

[0023] An operating chamber 2 is provided in the base 1, a rectangular tube 3 is vertically provided in the middle of the operating chamber 2, a rectangular seat 4 is provided in the rectangular tube 3, a screw hole for screw connection with a screw rod 5 is provided in the middle of the rectangular seat 4, and the screw rod 5 is driven by a motor 6. A plurality of clamping mechanisms 7 are provided on the top of the base 1 outside the rectangular tube 3, and the number of the clamping mechanisms 7 is four, wherein the plurality of clamping mechanisms 7 are evenly arranged on the base 1;

[0024] The clamping mechanism 7 includes a strip opening 72 radially arranged on the top of the base 1, and a splint 71 extending to the top of the base 1 is arranged in the strip opening 72. A limiting rod 73 and a spring 74 are arranged on the back of the splint 71. A fixing channel 75 for accommodating the limiting rod 73 and the spring 74 is arranged on the side wall of the strip opening 72. An L-shaped sliding channel 76 is also provided in the side wall of the base 1, and its two ends are respectively connected to the rectangular tube 3 opening and the corresponding strip opening 72. A chain 77 connected to the corresponding splint 71 and the rectangular seat 4 at both ends is provided in the sliding channel 76. An installation cavity 78 is provided at the corner of the sliding channel 76, and a sprocket 79 adapted to the corresponding chain 77 is provided in the installation cavity 78.

[0025] In this embodiment, the two ends of the rectangular tube 3 are fixedly connected to the upper and lower side walls of the operating chamber 2 respectively, and the size of the rectangular seat 4 is adapted to the size of the inner opening of the rectangular tube 3 to prevent the rectangular seat 4 from rotating inside the rectangular tube 3.

[0026] In this embodiment, one end of the spring 74 is fixedly connected to the back surface of the clamping plate 71 , and the other end of the spring 74 is fixedly connected to the side wall corresponding to the fixing channel 75 .

[0027] In this embodiment, a top side of the clamping plate 71 is provided with a boss 8 located above the base 1 , and an arc-shaped groove is provided on one end surface of the boss 8 , and a rubber layer is provided in the arc-shaped groove.

[0028] like Figure 1 As shown, an inlet and outlet communicating with the operating chamber 2 are provided on the side wall of the base 1, and a switch door is provided at the inlet and outlet.

[0029] When in use, the strip opening 72 is used to clamp the splint 71 and the polygonal fixing channel 75 to fix the matching limit rod 73, thereby effectively preventing the splint 71 from swinging during the movement. At the same time, the decorative cover is placed on the top of the base 1 between the four sets of protrusions 8. At this time, the motor 6 works to drive the screw rod 5 to rotate in the screw hole in the rectangular seat 4, thereby driving the rectangular seat 4 to move down in the rectangular tube 3, wherein the rectangular tube 3 clamps the rectangular seat 4 matched with it, preventing the rectangular seat 4 from rotating while allowing it to move up and down smoothly. When the rectangular seat 4 moves down, it will drive the four sets of chains 77 to move downward. At this time, the chain 77 will slide in the sliding channel 76 and also drive the sprocket 79 to rotate. When the chain 77 moves, it will also pull the splint 71 toward the middle of the base 1;

[0030] When the splint 71 moves, it will drive the limit rod 73 to slide in the fixed channel 75 and also stretch the spring 74. At the same time, the splint 71 also drives the protrusion 8 to move, thereby reducing the size of the opening formed by the four groups of protrusions 8, so that the four groups of protrusions 8 can lock and fix the decorative cover to the top of the base 1, so that the product can be clamped and fixed from multiple directions through multiple groups of splints 71 and protrusions 8 to prevent it from horizontal displacement during processing and affecting the processing work. After the processing is completed, the motor 6 drives the rectangular seat 4 to move upward through the screw rod 5. Then, under the pulling force caused by the loss of the rectangular seat 4 on the chain 77, the spring 74 contracts and drives the splint 71 to reset while pulling the chain 77 and driving the sprocket 79 to rotate, so that the four groups of splints 71 drive the protrusion 8 to reset, so as to facilitate the removal of the product and the processing of subsequent products.

[0031] The present invention has been described in detail above, but the contents described are only preferred embodiments of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
