[0042] A handlebar workpiece 2 is inserted on the surface of the connecting component 1. The handlebar workpiece 2 consists of a connecting portion and a gripping portion. The connecting portion is inserted in the interior of the sleeve 10. The main punching device 4 is used to process the connecting portion. The gripping portion is in a bent shape. The auxiliary punching device 7 is located outside the bent portion and uses the limit frame 22 to limit the bending angle of the bent portion during the swinging process to move and punch the bent portion.

When working, the main punching device 4 is sleeved It is arranged on the guide rod 13 and the screw rod 12, in the initial position, waiting for processing instructions. When the punching process needs to be started, the rotation of the screw rod 12 converts the rotational motion into linear motion through the threaded connection between it and the main punching device 4. As the screw rod 12 rotates, the main punching device 4 moves horizontally along the direction of the guide rod 13 under the drive of the screw rod 12. The existence of the guide rod 13 ensures the stability and directionality of the main punching device 4 during the movement, and prevents it from deviating from the predetermined path. When the main punching device 4 moves to the position in contact with the handlebar workpiece 2, the punching process starts.

[0047] As a technical optimization solution of the present invention, the horizontal movement and precise positioning of the main punching device 4 are achieved by utilizing the combination of the screw rod 12 and the guide rod 13. The rotation of the screw rod 12 drives the main punching device 4 to move smoothly through the threaded connection, while the guide rod 13 provides sliding support to ensure the stability of the main punching device 4 during movement.

During the movement of the transmission structure 3, the linkage structure 6 can be used to push the clamping plate 15 to swing.

[0049] As a technical optimization solution of the present invention, the reliable fixation of the handlebar workpiece 2 is achieved through the cooperation of the shaft rod 14 and the clamping plate 15. As the transmission structure 3 moves, the linkage structure 6 pushes the clamping plate 15 to swing, thereby driving the clamping plate 15 to clamp the handlebar workpiece 2. This automatic clamping design not only improves the processing efficiency, but also avoids the processing error caused by the loosening of the workpiece.

[0050] refer to Figure 4 The linkage structure 6 includes an extension rod 16 fixedly connected to both sides of the bottom of the main punching device 4, and a sleeve plate 17 is fixedly connected to the side of the clamping plate 15 close to the shaft rod 14. The sleeve plate 17 is in a bent shape. When the slide bar 18 slides on the curved part of the surface of the sleeve plate 17, the sleeve plate 17 is squeezed to drive the clamping plate 15 to swing. When the slide bar 18 moves from the curved part to the horizontal part, the sleeve plate 17 is ensured to be different and the slide bar 18 can normally follow the extension rod 16 to move horizontally. The side of the extension rod 16 away from the main punching device 4 extends to the outside of the sleeve plate 17, and the side of the extension rod 16 close to the sleeve plate 17 is fixedly connected with the slide bar 18, and the side of the slide bar 18 away from the extension rod 16 extends to the inside of the sleeve plate 17.

This design not only realizes the opening and closing fixation of the positioning structure 5, but also ensures the synchronization of the positioning process and the punching process. In addition, the setting of the angle plate 32 enhances the strength of the extension rod 16, and the hollow design reduces the weight, which is beneficial to the overall balance of the equipment.

[0052] refer to Figure 5 The driving component 8 includes a fork 19 fixedly connected to both ends of the shaft 14, and the auxiliary punching device 7 is slidably connected to the inside of the fork 19 through an adjusting structure 20. The adjusting structure 20 can drive the auxiliary punching device 7 to slide inside the fork 19 and drill the handlebar workpiece 2 during the swinging process of the shaft 14 carrying the fork 19.

When the model of the handlebar workpiece 2 changes, the user can synchronously replace the limit frame 22 to ensure the alignment accuracy of the auxiliary punching device 7 and the handlebar workpiece 2. The limit frame 22 is sleeved on the surface of the output end of the auxiliary punching device 7, and the surface of the auxiliary punching device 7 is fixedly connected with a sliding tube 23 sleeved on the surface of its output end. The sliding tube 23 is located inside the limit frame 22 and is slidably connected to the limit frame 22. When the shaft rod 14 drives the fork 19 to swing, the auxiliary punching device 7 can slide inside the fork 19 through the limit of the limit frame 22 and make the auxiliary punching device 7 always parallel to the handle workpiece.

[0055] As a technical optimization solution of the present invention, the cooperation of the limit frame 22 and the sliding tube 23 ensures that the auxiliary punching device 7 always remains parallel to the handlebar workpiece 2 during the swinging process. This design not only simplifies the adjustment process, but also improves the punching quality. At the same time, the design of the adjustment structure 20 also provides convenience for subsequent maintenance and upgrades.

A rotary switch 33 is provided on the surface of the wheel disc 30. When the wheel disc 30 rotates one circle, the rotary switch 33 can be triggered. When the rotary switch 33 is triggered, the electric hydraulic rod 25 can be controlled to operate.

[0059] As a technical optimization solution of the present invention, intermittent rotation of the screw 12 is achieved by setting a drive motor 29, a wheel disc 30 and a push rod 31, which not only simplifies the transmission structure 3, but also improves the transmission efficiency. At the same time, the intermittent rotation design also helps to reduce energy consumption and reduce equipment wear.

[0060] refer to Figure 4 A corner plate 32 is fixedly connected to the surface of the extension rod 16, and the corner plate 32 is configured to be hollow.

[0062] The working principle and use process of the present invention are as follows: the handlebar workpiece 2 is inserted into the sleeve 10 of the connecting component 1, at which time the positioning structure 5 clamping plate 15 is in an unclamped state, the main punching device 4 and the auxiliary punching device 7 are both in the initial position, and the core part of the screw 12 transmission structure 3 is movably connected to the inner side of the vertical plate 11 through a bearing, one end of the screw 12 extends out of the vertical plate 11 and is fixedly connected to a wheel flap 27, and the wheel flap 27 and the output end of the drive motor 29 maintain a certain initial position relationship through the wheel disc 30 and the push rod 31. When the drive motor 29 is started, its output end drives the wheel disc 30 to rotate. The push rod 31 on the wheel disc 30 rotates accordingly. When the push rod 31 enters the inside of the wheel disc 27, the two mesh and push the wheel disc 27 and the connected screw rod 12 to rotate. The rotation of the screw rod 12 drives the main punching device 4 to move horizontally on the guide rod 13 through the threaded connection and approach the handlebar workpiece 2. As the main punching device 4 moves, the extension rod 16 at its bottom also moves synchronously. The slide rod 18 on the extension rod 16 slides inside the sleeve plate 17. When the slide rod 18 applies sufficient lateral force to the sleeve plate 17, The sleeve plate 17 drives the shaft 14 and the clamping plates 15 on both sides to swing, and the clamping plates 15 gradually approach and clamp the handlebar workpiece 2, fixing it inside the sleeve 10 to ensure stability during the punching process. The main punching device 4 continues to move until it contacts the handlebar workpiece 2 and starts punching the workpiece. During the swinging of the clamping plate 15, due to the swinging of the shaft 14, the auxiliary punching device 7 connected by the fork 19 also swings synchronously, so that its output end is aligned with a specific position of the handlebar workpiece 2, and the wheel petal 27 is intermittent. When the rotation is completed and enters the static state, the electric hydraulic rod 25 drives the auxiliary punching device 7 to slide inside the fork 19 and move inward until its output end contacts the workpiece and starts punching. During the swinging of the fork 19, the auxiliary punching device 7 maintains consistency with the curved shape of the handlebar workpiece 2 through the limiting effect of the limit frame 22. The auxiliary punching device 7 limited by the limit frame 22 can be lifted and moved inside the fork 19 through the sliding tube 23 to ensure the accuracy of the punching alignment. The electric hydraulic rod 25 further drives the auxiliary punching device 7 to move inward to deeply process the handlebar workpiece 2, and completes the punching operation of multiple holes each time the wheel petal 27 stops intermittently. When the main punching device 4 and the auxiliary punching device 7 complete the punching, the drive motor 29 reverses, drives the screw 12 to rotate in the opposite direction, and makes the main punching device 4 return to the initial position. At the same time, the linkage structure 6 loosens the clamp 15 and releases the handlebar workpiece 2. At this time, a new handlebar workpiece 2 can be replaced, and the above steps are repeated for the next round of punching.

[0063] To sum up: the core of the multi-station automatic punching device for handlebar processing lies in the integration of multiple functional modules such as the connecting component 1, the transmission structure 3, the positioning structure 5, the linkage structure 6 and the auxiliary punching device 7, which realizes efficient and accurate punching of the handlebar workpiece 2.
