In order to solve this technical problem, this utility model proposes a punching device for the connecting plate on the steering column. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In the prior art, when punching holes in the connecting plate on the steering column, the traditional device first needs to fix the connecting plate. However, the traditional fixing fixture has a relatively simple structure and can only be used for one type of connecting plate. When different types of connecting plates need to be fixed, the fixture or the equipment needs to be changed before processing, which greatly reduces the work efficiency. In order to solve this technical problem, this utility model proposes a punching device for the connecting plate on the steering column.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a punching device for a connecting plate on a steering column, comprising a base, a housing fixedly connected to the top of the base, an inner cavity inside the housing, a one-way threaded rod rotatably connected inside the housing, a connecting block threadedly connected to the outer wall of the one-way threaded rod, a pair of springs fixedly connected to each of the two side walls of the housing, a push plate fixedly connected to the other end of each spring, a slider fixedly connected to the inner side wall of each push plate, the slider slidably connected inside the housing, and a connecting plate body provided outside the housing.

[0008] Preferably, both ends of the connecting block are inclined, and one end of each of the two sliders is also inclined, with the sliders corresponding to the connecting block.

[0009] Preferably, a bracket is fixedly connected to the top of the base, and a pair of mounting plates are fixedly connected to the inner sidewalls below the bracket. A bidirectional threaded rod is rotatably connected between the two mounting plates, and a positioning plate is threaded to the outer wall at both ends of each bidirectional threaded rod.

[0010] Preferably, a positioning rod is fixedly connected between the two mounting plates, and one end of the positioning plate is slidably connected to the outer wall of the positioning rod, while the other end of the positioning plate is slidably connected to the top of the base.

[0011] Preferably, an electric push rod one is fixedly connected to the top of the bracket, a fixed frame is fixedly connected to the output end of the electric push rod one, an electric push rod two is fixedly connected inside the fixed frame, and a punching head is fixedly connected to the output end of the electric push rod two.

[0012] Preferably, a limiting groove is provided at the top of the bracket, and limiting blocks are fixedly connected to both sides of the fixed frame, with the limiting blocks slidably connected in the limiting groove, while the fixed frame is slidably connected to the bracket.

[0013] (III) Beneficial Effects

[0014] This utility model provides a punching device for a connecting plate on a steering column. It has the following advantages:

[0015] (1) Rotate the one-way threaded rod inside the outer shell to drive the connecting block to move. When the connecting block moves to the inner end of the slider, it uses its inclined surface to push the slider to move to both sides. The slider drives the extrusion plate to clamp and fix the inner diameter of the connecting plate body located in the inner cavity. During the process, the spring is in a stretched state. This device solves the problems of unstable fixing and complicated operation of existing connecting plates. Traditional methods cannot adapt to connecting plates of different sizes or the fixing process is cumbersome. This device can quickly and stably fix the connecting plate body of different inner diameters through the cooperation of various components, which improves the convenience and accuracy of processing, provides a reliable foundation for subsequent processing, and improves the overall work efficiency.

[0016] (2) A mounting plate is installed on the bracket, and the rotating bidirectional threaded rod on the mounting plate plays a key role. When the bidirectional threaded rod rotates, it drives the positioning plates at both ends to move in opposite directions. The positioning rod passes through the positioning plate and limits its movement, ensuring that the positioning plate moves stably in the predetermined direction. This device solves the problems of inaccurate positioning and low efficiency of existing devices for connecting plates. Traditional methods may find it difficult to quickly and accurately locate the position of the connecting plate, affecting processing accuracy and efficiency. These components work together to accurately position the connecting plate, avoid deviations during processing, make subsequent operations smoother, greatly improve positioning efficiency and processing accuracy, and reduce material waste and time loss caused by positioning errors.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] Example 1: A punching device for a connecting plate on a steering column, comprising a base 1, a housing 2 fixedly connected to the top of the base 1, an inner cavity 8 inside the housing 2, a one-way threaded rod 3 rotatably connected inside the housing 2, a connecting block 4 threadedly connected to the outer wall of the one-way threaded rod 3, a pair of springs 6 fixedly connected to each side wall of the housing 2, a push plate 7 fixedly connected to the other end of each spring 6, a slider 5 fixedly connected to the inner wall of each push plate 7, the slider 5 slidably connected inside the housing 2, a connecting plate body 9 provided outside the housing 2, the two ends of the connecting block 4 being inclined, and the two sliders 5 simultaneously... One end is set in an inclined shape, and the slider 5 corresponds to the connecting block 4. The top of the base 1 is fixedly connected to the bracket 10. The top of the bracket 10 is provided with a limiting groove 19. The two side walls of the fixed frame 16 are fixedly connected to the limiting blocks 17, and the limiting blocks 17 are slidably connected in the limiting groove 19. At the same time, the fixed frame 16 is slidably connected to the bracket 10. The top of the bracket 10 is fixedly connected to the electric push rod 15. The output end of the electric push rod 15 is fixedly connected to the fixed frame 16. The inside of the fixed frame 16 is fixedly connected to the electric push rod 28. The output end of the electric push rod 28 is fixedly connected to the punch head 20.

[0025] First, rotate the one-way threaded rod 3 inside the outer casing 2. As the one-way threaded rod 3 rotates, the connecting block 4 begins to move back and forth. When one side of the connecting block 4 moves to the inner end of the slider 5, its outer surface is inclined, which pushes the slider 5 to both sides. The slider 5 then drives the extrusion plate 7 to move outward, thereby clamping and fixing the inner diameter of the connecting plate body 9. At this time, the spring 6 is stretched. After the fixing is completed, the electric push rod 15 at the top of the bracket 10 is activated. Under its push, the fixed frame 16 and the electric push rod 18 inside it begin to move and adjust to ensure that the stamping head 20 reaches the stamping position. Then, the electric push rod 18 is activated to drive the stamping head 20 to move down and perform stamping operation on the connecting plate body 9. When the fixed frame 16 moves, it is limited by the limit block 17 in the limit groove 19 to ensure the stability of the movement. After the stamping is completed, the one-way threaded rod 3 is rotated in the opposite direction to make the connecting block 4 disengage from one end of the slider 5. The spring 6 uses its elasticity to reset the slider 5 and the extrusion plate 7, preparing for the next processing. The components work together seamlessly, greatly improving work efficiency.

[0026] Example 2: The difference between this example and Example 1 is that a pair of mounting plates 11 are fixedly connected to the inner sidewall of the bracket 10 below, and a bidirectional threaded rod 12 is rotatably connected between the two mounting plates 11. A positioning plate 13 is threadedly connected to the outer wall of each end of the bidirectional threaded rod 12. A positioning rod 14 is fixedly connected between the two mounting plates 11, and one end of the positioning plate 13 is slidably connected to the outer wall of the positioning rod 14, and the end of the positioning plate 13 is slidably connected to the top of the base 1.

[0027] Place the connecting plate body 9 on top of the outer casing 2. To achieve precise positioning, begin rotating the bidirectional threaded rods 12 on the mounting plates 11 on both sides. As the bidirectional threaded rods 12 rotate, each end of them drives a positioning plate 13 to move in the opposite direction. During this process, the positioning rod 14 plays a role in limiting the movement of the positioning plates 13, ensuring the stability and accuracy of the movement. With the continuous rotation of the bidirectional threaded rods 12, the positioning plates 13 gradually move towards the center, eventually pressing tightly against the connecting plate body 9, thus achieving precise positioning. This operation ensures accurate positioning when subsequently clamping and fixing the connecting plate body 9, greatly improving work efficiency.

[0028] Working principle: When the operator needs to stamp the connecting plate on the steering column, the connecting plate body 9 is first placed on the outer shell 2. By rotating the bidirectional threaded rods 12 on the mounting plates 11 on both sides, the positioning plates 13 on both ends move in opposite directions under the action of the bidirectional threaded rods 12. The positioning plates 13 are limited by the positioning rods 14 during movement. At this time, the positioning plates 13 move towards the middle and position the connecting plate body 9, ensuring accurate positioning during clamping and fixing, thus improving work efficiency. After positioning, the one-way threaded rod 3 inside the outer shell 2 is rotated. When the one-way threaded rod 3 rotates, it will drive the connecting block 4 to move back and forth. When the slider 5 moves to its inner end, its outer surface is inclined, pushing it to both sides. The slider 5 moves outward, causing the extrusion plate 7 to move outward as well. The extrusion plate 7 clamps and fixes the inner diameter of the connecting plate body 9. Simultaneously, the spring 6 is stretched. After fixing, the electric push rod 15 at the top of the bracket 10 is activated. Under the action of the electric push rod 15, the fixed frame 16 and the internal electric push rod 18 are moved and adjusted to ensure the punch head 20 is in the punching position. Then, the electric push rod 18 is activated to move the punch head 20 downward, thus performing the punching operation on the connecting plate body 9. When the fixed frame 16 moves, it is limited within the limiting groove 19 by the limiting block 17. After punching, the one-way threaded rod 3 is rotated in the opposite direction, causing the connecting block 4 to disengage from one end of the slider 5. The spring 6 then uses its elasticity to reset the slider 5 and the extrusion plate 7, facilitating the next processing. Their cooperation greatly improves work efficiency.
