Description

Technical Field

[0001] The utility model relates to the technical field of electric tricycle hub processing and punching, and particularly relates to a punching device for electric tricycle hub processing. Background Technique

[0002] An electric tricycle hub processing and punching device is a mechanical device specifically used for punching operations on the hubs of electric tricycles.

[0003] During the punching process of existing automobile hubs, the positioning and clamping of the automobile hubs are not firm enough. The automobile hubs are prone to sliding during the punching process, resulting in position deviation, which leads to inaccurate punching positions and is not conducive to the punching operation. Now, there is an urgent need for an automobile hub that is convenient for punching to solve the above problems.

[0004] A Chinese patent with the publication number CN212945554U discloses an automobile hub convenient for punching, including a drilling head, an automobile hub main body, a support plate, an adjusting handle, a screw rod, a positioning clamping ring, a rotating wheel disc, a driving motor, a punching platform, a transmission shaft, and a rubber protective pad. A drilling head is arranged on the upper side of the automobile hub main body, a punching platform is arranged on the lower side of the automobile hub main body, a driving motor is installed on the lower side of the punching platform, a transmission shaft is installed on the upper side of the driving motor, a rotating wheel disc is installed on the upper side of the transmission shaft, support plates are fixed on the left and right sides of the upper end surface of the punching platform, a screw rod is installed inside the support plate, an adjusting handle is installed on the left end surface of the screw rod, a positioning clamping ring is installed on the right side of the screw rod, and a rubber protective pad is arranged at the connection between the inner side of the positioning clamping ring and the automobile hub main body. This design solves the problem of insufficient firm fixation during the punching of the original automobile hub. The utility model has a reasonable structure, is convenient for combined installation, has a good positioning and fixation effect, and a high punching efficiency.

[0005] In view of the above problems, the existing patent gives a solution. However, the above solution has certain defects during use. After the drill bit punches a hole, it is still necessary for the staff to polish the punching position. The efficiency is slow, and the effect of manual polishing is not very ideal. Moreover, when the outer side of the hub is fixed through the positioning clamping ring, if the fixing force is too large, it is easy to deform the protective pad, thereby easily scratching the outer side of the hub, which affects the installation effect of the later tire.

[0006] Therefore, a punching device for electric tricycle hub processing is proposed. Content of the Utility Model

[0027] Please refer to Figures 1-5 , the present invention provides a technical solution:

[0028] A punching device for processing an electric tricycle hub includes a processing rack 1. A first electric telescopic column 4 is fixedly connected to the top of the processing rack 1.

The opposite sides of the second grinding block 1005 and the first grinding block 1001 respectively contact the top and bottom of the hub body 8.

[0030] In this embodiment: By fixedly connecting the tops of the first motor 2 and the second motor 5 to the bottom of the connecting frame 3, it is convenient for the first electric telescopic column 4 to drive the first motor 2 and the second motor 5 to lift through the connecting frame 3, move the hub body 8 to the top of the rotating disc 7, and then it is convenient to drill holes through the second motor 5.

Then, it is convenient for the sequencing cone block 1002 to drive the connecting block 1003 to move into the connecting groove 1004. Thus, it is convenient for the first motor 2 to drive the second grinding block 1005 to rotate through the first grinding block 1001, and then the first grinding block 1001, the sequencing cone block 1002, and the second grinding block 1005 can perform grinding, thereby improving the efficiency of hub processing.

[0031] Specifically, as Figure 2 , Figure 3 shown, two fixed arc blocks 903 are arranged on the top of the rotating disc 7. A protective block 904 is fixedly connected to the top of the fixed arc block 903. Opposite sides of the two fixed arc blocks 903 are in close contact with the inner wall of the hub body 8.

[0032] Specifically, as Figure 2 , Figure 3 , Figure 5 shown, two fixed slots 13 are opened on the top of the rotating disc 7.

[0034] In this embodiment: By making opposite sides of the two fixed arc blocks 903 in close contact with the inner wall of the hub body 8, it is convenient for the fixed arc blocks 903 to fix the hub body 8, achieving the effect of fixing the hub body 8.

[0035] Specifically, as Figure 4 shown, a bearing 11 is rotatably connected to the bottom of the second grinding block 1005. The top of the first grinding block 1001 is fixedly connected to the bottom of the rotating frame 6.

[0036] Specifically, as Figure 2 , Figure 4 shown, a rotating rod 12 is rotatably connected to the inside of the rotating disc 7. The top of the rotating rod 12 extends into the inside of the bearing 11 and is fixedly connected to the inside of the bearing 11.

[0038] Specifically, as Figure 1 shown, a protective cover 14 is provided inside the processing frame 1, and the bottom of the protective cover 14 is fixedly connected to the top of the rotating disk 7.

[0039] Specifically, as Figure 1 shown, a drilling tool 15 is fixedly connected to the bottom of the output shaft of the second motor 5, and the bottom of the drilling tool 15 passes through the hub body 8 and extends to the bottom of the hub body 8.

[0040] In this embodiment: By fixedly connecting the bottom of the protective cover 14 to the top of the rotating disk 7, the protective cover 14 can limit the hub body 8, achieving the effect of limiting the hub body 8.

[0041] Working principle: When drilling the hub body 8, make the top of the protective block 904 contact the bottom of the hub body 8, so as to conveniently move the hub body 8 to the top of the rotating disk 7, and the protective cover 14 performs limiting and protection. Then, it is convenient for the second electric telescopic column 901 to drive the moving block 902 to move through the fixed slot 13, and the moving block 902 drives the fixed arc block 903 to move, so that the opposite sides of the two fixed arc blocks 903 are in close contact with the inner wall of the hub body 8, and the hub body 8 can be fixed, avoiding damage to the outside of the hub body 8. Drive the drilling tool 15 to drill through the output shaft of the second motor 5, and then make the rotating disk 7 drive the hub body 8 to rotate, so that the first grinding block 1001 moves into the drilled hole through the alignment cone block 1002. Then, it is convenient for the alignment cone block 1002 to drive the connecting block 1003 to move into the connecting slot 1004, and then it is convenient for the first motor 2 to drive the second grinding block 1005 to rotate through the first grinding block 1001. The second grinding block 1005 rotates on the surface of the rotating rod 12 through the bearing 11, so that the first grinding block 1001, the alignment cone block 1002 and the second grinding block 1005 can perform grinding, thus improving the efficiency of hub processing, solving the problem that after drilling with a drill bit, it is still necessary for workers to grind the drilled position, which is slow in efficiency and the manual grinding effect is not ideal. Moreover, when fixing the outside of the hub through the positioning snap ring, if the fixing force is too large, the protective pad is easily deformed, and the outside of the hub is easily scratched, thus affecting the installation effect of the later tire.
