[0002] In the machining process of mechanical parts, punching is a common and important process. For mechanical parts of different shapes and sizes, especially ring parts, the traditional punching clamp has many limitations. The traditional clamp is usually single in structure and can only clamp parts of specific shapes or sizes, which is poor in universality. When clamping ring parts, it is difficult to simultaneously meet the demand for punching the cross section and the arc surface of the parts, and different clamps or clamping modes of the parts need to be adjusted, which not only increases the complexity and workload of operation, but also reduces the machining efficiency. Moreover, when clamping parts, the traditional clamp usually cannot realize synchronous and accurate adjustment of multiple clamping points, which easily leads to insecure clamping of the parts or uneven force, affecting the precision and quality of punching, and even causing damage to the parts during punching, increasing the production cost.

[0015] BRIEF DESCRIPTION OF DRAWINGS DETAILED DESCRIPTION

[0016] The following will be described in detail in combination with the accompanying drawings Figs. 1-3 The present application will be further described in detail.

[0017] The embodiment of the present application discloses a mechanical part punching clamp. Referring to Figs. 1-3 A mechanical part punching clamp, comprising a support plate 1, a connecting assembly 3, a clamping assembly 4, a driving assembly 2 and a guide assembly 5, each component cooperates to realize accurate clamping and flexible positioning of ring-shaped mechanical parts, meet different punching position requirements, and significantly improve the efficiency and accuracy of punching operation.

[0018] Referring to Fig. 1The support plate 1 is the base bearing platform of the whole clamp, and the bottom thereof can be mounted on the mounting foot through bolts to provide stable mounting sites for other components. The connecting assembly 3 at the bottom thereof endows the clamp with flexible positioning adjustment capability. The sliding sleeve 301 in the connecting assembly 3 is hinged on the support plate 1, and this hinging mode enables the sliding sleeve 301 to rotate flexibly relative to the support plate 1, laying a foundation for subsequent adjustment of the positioning hole 6 at different angles. The sliding rod 302 is slidably arranged in the inner side of the sliding sleeve 301, and can smoothly slide in the sliding sleeve 301 to realize length direction adjustment, further expanding the flexibility of positioning. The telescopic rod 303 is hinged at one end of the sliding rod 302, and through the telescopic function, the overall length can be accurately controlled, and in cooperation with the sliding sleeve 301 and the sliding rod 302, the positioning hole 6 can be accurately positioned to the punching position of the cross section or arc surface of the part. The sliding rod 302 and the telescopic rod 303 are both provided with the positioning hole 6 at the end away from each other, and these positioning holes 6 are used to determine the punching position, and whether the part cross section is drilled or the arc surface is drilled, the punching equipment can be aligned with the positioning hole 6 by adjusting the state of the sliding sleeve 301, the sliding rod 302 and the telescopic rod 303, and the accuracy of punching is ensured.

[0019] With reference to Fig. 2The clamping assembly 4 is responsible for stable clamping of the ring-shaped part. The clamping blocks 401 are slidingly arranged in the sliding grooves of the support plate 1, and the sliding grooves provide accurate movement guidance for the clamping blocks 401, so that the clamping blocks 401 can only move radially, ensuring the directionality and stability of the clamping action. The three clamping blocks 401 move radially around the hinge point of the sliding sleeve 301, and this layout enables uniform force to be applied when clamping the ring-shaped part, and the part is fixed from multiple directions. The sliding blocks 403 on the clamping blocks 401 slide in the sliding grooves, and the sliding blocks 403 are synchronously moved by the synchronous mechanism. The driving assembly 2 in the synchronous mechanism is composed of a double-headed screw 201 rotating on the support plate 1 and a moving block 202 and a moving seat 203 at both ends of the double-headed screw 201. The rotation of the double-headed screw 201 is the power source for moving the clamping blocks 401. Since the pitch ratio of the thread segments where the moving block 202 and the moving seat 203 are located on the double-headed screw 201 is 1:2, when the double-headed screw 201 rotates, the moving block 202 and the moving seat 203 will move towards or away from each other at different speeds according to the screw transmission principle. This speed difference design is ingenious, and through reasonable mechanical transmission, accurate synchronous driving of the three clamping blocks 401 is achieved, so that the three clamping blocks 401 can simultaneously and uniformly approach or move away from the ring-shaped part, ensuring that the part is stably clamped at the center position. The movement of the moving seat 203 drives the clamping blocks 401 to move radially synchronously through the guide assembly 5. The connecting blocks 501 in the guide assembly 5 are fixed on the clamping blocks 401, and as the clamping blocks 401 move, the guide rods 502 on the connecting blocks 501 slide in the moving seat 203. The sliding connection of the guide rods 502 and the moving seat 203 provides stable support and guidance for the movement of the clamping blocks 401, ensuring the stability and directionality of the movement of the clamping blocks 401, avoiding deviation or shaking of the clamping blocks 401 during movement, and thus ensuring the accuracy and reliability of clamping the part. Flexible pads 402 are arranged on the side of the clamping blocks 401 that approach each other, and the flexible pads 402 are usually made of soft materials such as rubber or silicone. When clamping the part, the flexible pads 402 come into direct contact with the surface of the part, effectively buffering the clamping force, preventing the part from being damaged by the clamping force, and protecting the appearance and surface quality of the part. Especially for mechanical parts with high surface precision, the presence of the flexible pads 402 is crucial.

[0020] The implementation principle of the mechanical part punching clamp according to an embodiment of the present application is as follows:

[0021] Before performing the punching operation on the ring-shaped part in the mechanical processing workshop, the punching clamp is installed on the machine tool workbench to ensure that the support plate 1 is firmly and horizontally installed. The ring-shaped part to be processed is placed on the support plate 1, and at this time the ring-shaped part is in an initial state of not being clamped.

[0022] The operator rotates the double screw rod 201, and the rotating movement of the double screw rod 201 is converted into the linear movement of the moving block 202 and the moving seat 203 according to the thread segments with different pitches at the two ends of the double screw rod 201. Due to the connecting effect of the guide assembly 5, the linear movement of the moving seat 203 drives the clamping blocks 401 to move radially along the sliding grooves on the support plate 1. During the movement, the sliding block 403 slides smoothly in the sliding groove, and the sliding of the guide rod 502 in the moving seat 203 further ensures the accuracy and stability of the movement of the clamping blocks 401. The three clamping blocks 401 synchronously approach the ring-shaped part, the flexible pads 402 first contact the part, and as the clamping blocks 401 continue to move, the flexible pads 402 are gradually compressed to apply uniform clamping force to the part, so that the part is firmly fixed on the support plate 1.

[0023] After the part is clamped and fixed, the position of the positioning hole 6 is adjusted according to the specific position requirement of punching. If the part cross section needs to be punched, the positioning hole 6 is located at the appropriate position of the part cross section by adjusting the hinged angle of the sliding sleeve 301 and the sliding position of the sliding rod 302 in the sliding sleeve 301, and the telescopic rod 303 can be used for fine adjustment to ensure that the positioning hole 6 is accurately aligned with the position of the punching tool. If the part arc surface needs to be punched, the hinged angle of the sliding sleeve 301, the sliding of the sliding rod 302 in the sliding sleeve 301 and the telescopic length of the telescopic rod 303 need to be comprehensively adjusted, so that the positioning hole 6 can be accurately positioned at the punching point of the arc surface. After the positioning hole 6 is adjusted to the correct position, the punching device of the machine tool is started, the drill bit punches the part through the positioning hole 6. Since the part is stably clamped and accurately positioned, the punching precision and quality can be ensured, and the machining efficiency is improved.
