[0007] Furthermore, a third servo electric cylinder is installed at the top of the base near the central end through a fixing groove, the power output end of the third servo electric cylinder is connected to a displacement plate, and a fourth servo electric cylinder is installed on the top of the displacement plate through screws. When working, the third servo electric cylinder drives the displacement plate to move up and down, thereby facilitating the up and down movement of the fourth servo electric cylinder as needed.

[0008] Furthermore, a power output end of the fourth servo electric cylinder is connected to a tool spindle.

[0009] Furthermore, guide pillars are welded at the top of the mounting frame near both ends of the first servo electric cylinder, guide rods are connected to both sides of the top of the disc displacement block, and the top ends of the guide rods are located in the corresponding guide pillars.

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0017] like Figure 1-3 As shown, a bicycle wheel rim punching device includes a base 1, a mounting frame 2, a fourth servo electric cylinder 14 and a tool spindle 15. A first servo electric cylinder 3 is arranged at the top of the mounting frame 2 near the center through a fixed seat, and a disc displacement block 4 is connected to the power output end of the first servo electric cylinder 3. A servo motor 7 is installed at the bottom of the disc displacement block 4 near the center through a fixed groove, and the output shaft of the servo motor 7 is connected to a rotating block 8. A mounting seat 9 is arranged on the periphery of the rotating block 8, and a second servo electric cylinder 10 is fixedly installed on the outer side of the mounting seat 9 by bolts, and a U-shaped plate 11 is connected to the power output end of the second servo electric cylinder 10.

[0018] Among them, a third servo electric cylinder 12 is installed at the top of the base 1 near the central end through a fixing groove, the power output end of the third servo electric cylinder 12 is connected to a displacement plate 13, and a fourth servo electric cylinder 14 is installed on the top of the displacement plate 13 through screws.

[0019] In this embodiment, Figure 1-3 As shown, the third servo electric cylinder 12 drives the displacement plate 13 to move up and down when working, so as to facilitate the up and down movement of the fourth servo electric cylinder 14 as needed.

[0020] The power output end of the fourth servo electric cylinder 14 is connected to a tool spindle 15 .

[0021] In this embodiment, Figure 1-3 As shown, the fourth servo electric cylinder 14 conveniently drives the tool spindle 15 to move horizontally when working.

[0022] Among them, guide pillars 5 are welded at the top of the mounting frame 2 near the two ends of the first servo electric cylinder 3, and guide rods 6 are connected to both sides of the top of the disc displacement block 4, and the top ends of the guide rods 6 are located in the corresponding guide pillars 5.

[0023] In this embodiment, Figure 1-3 As shown, the limiting and guiding effect of the guide column 5 on the guide rod 6 can effectively improve the stability of the disc displacement block 4 when it moves up and down.

[0024] It should be noted that the utility model is a bicycle wheel rim punching device. When working, the first servo electric cylinder 3 drives the disc displacement block 4 to rise and fall, so that the U-shaped plate 11 rises and falls. The second servo electric cylinder 10 drives the U-shaped plate 11 to move horizontally when working. The number of the second servo electric cylinders 10 is specifically set to three groups, and they are evenly distributed along the circumference of the bottom center of the rotating block 8. The U-shaped plate 11 can be driven to clamp the bicycle wheel rim to be punched as needed. The third servo electric cylinder 12 drives the displacement plate 13 to rise and fall when working, and the tool spindle 15 is clamped inside. Holding a drilling tool, the fourth servo electric cylinder 14 drives the tool spindle 15 to move horizontally when working, so that the drilling tool drills the bicycle rim, and the servo motor 7 drives the rotating block 8 to rotate, so that the bicycle rim rotates, which is convenient for punching holes at different positions of the inner wall of the bicycle rim. Since the second servo electric cylinder 10 can drive the U-shaped plate 11 to move to different positions, the punching device has a clamping and positioning structure that can facilitate the adjustment of the clamping block, and can conveniently clamp automobile rims of different diameters, thereby facilitating the punching work.
