Description

Technical Field

[0001] This utility model relates to the field of punching technology, specifically to a punching clamp body. Background Technology

[0002] After welding, automotive subframes require punching. Currently, the two most commonly used punching pliers are straight-punch pliers and scissor pliers. Straight-punch pliers occupy more space in the punching axial direction but less in the radial direction; scissor pliers, through a lever structure, occupy less space in the punching axial direction but more in the radial direction. Both types work together to avoid obstructing the subframe structure during punching. The subframe structure is as follows: Figure 1 As shown, it has the following: Figure 2 The U-shaped cavity structure shown requires punching on both side plates 01. Due to the limitations of the surrounding space, in the prior art, the two side plates 01 can only be punched using a straight punch clamp and a scissor clamp respectively. In order to avoid interference between the two clamps, the punching process must be carried out in steps. That is, after punching one side plate 01, the clamp must be changed before punching the other side plate 01. It is impossible to complete the punching of the two side plates 01 simultaneously, resulting in low processing efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a punching clamp that addresses the problem that in the prior art, when punching holes in the two side plates of the U-shaped cavity structure on the subframe of an automobile, it is necessary to use a straight punch clamp and a scissor clamp respectively, and the processing needs to be carried out in steps, resulting in low processing efficiency.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A punching clamp body includes a clamp body base, on which a first telescopic cylinder and a second telescopic cylinder are provided; the cylinder body of the first telescopic cylinder is fixed to the clamp body base, and the cylinder body of the second telescopic cylinder is hinged to the clamp body base; a first punch is provided at the end of the piston rod of the first telescopic cylinder; one end of the clamp body base is hinged to the middle of a lever; one end of the lever is hinged to the end of the piston rod of the second telescopic cylinder, and the other end is provided with a second punch; a protruding support block is formed on the clamp body base; the support block can be embedded between two side plates to be punched to form support, and a first die and a second die are respectively provided on opposite sides of the support block; the first telescopic cylinder can drive the first punch and the first die to cooperate in punching one side plate, and the second telescopic cylinder can drive the second punch and the second die to cooperate in punching the other side plate.

[0005] The present invention, employing the aforementioned technical solution, comprises a first telescopic cylinder, a first punch, and a first die forming a straight-punch structure, and a second telescopic cylinder, a lever, a second punch, and a second die forming a scissor-type punch structure. These structures can be used for punching two side plates of a U-shaped cavity structure on a subframe. Specifically, during processing, a support block is first embedded between the two side plates to provide support. Then, the piston rod of the first telescopic cylinder extends, directly driving the first punch to move and cooperate with the first die to punch a hole in one side plate; the piston rod of the second telescopic cylinder extends... After being transmitted by the lever, the second punch moves and cooperates with the second die to punch a hole in the other side plate; the punching process of the two side plates is carried out simultaneously. Compared with the prior art, when punching two side plates of the U-shaped cavity structure on the subframe of an automobile, it is necessary to use a straight punch clamp and a scissor clamp respectively, and the processing needs to be carried out in steps, resulting in low processing efficiency. This utility model can punch two side plates of the U-shaped cavity structure on the subframe of an automobile, and the punching process of the two side plates is carried out simultaneously, which improves processing efficiency.

[0006] Furthermore, the clamp base includes a base body that is generally strip-shaped and a first connecting seat and a second connecting seat fixed on the base body. The cylinder body of the first telescopic cylinder is fixed on the first connecting seat, and the cylinder body of the second telescopic cylinder is hinged on the second connecting seat. By setting the shape of the first connecting seat to fit the shape of the cylinder body of the first telescopic cylinder, it is easier to make the connection more stable. By setting the shape of the second connecting seat to fit the shape of the cylinder body of the second telescopic cylinder, it is easier to install the hinge shaft.

[0007] Furthermore, the clamp base is provided with a slide rail, which is parallel to the length direction of the first telescopic cylinder; it also includes a slider, one end of which is fixedly connected to the piston rod of the first telescopic cylinder, and the other end is slidably mounted on the slide rail; with this configuration, the slider can limit the radial displacement of the piston rod, ensuring that the piston rod can stably extend and retract along the axial direction, and ensuring the accuracy of the punching position.

[0008] Furthermore, each end of the slide rail is provided with a limiting block, and the limiting blocks are fixedly installed on the clamp base; these blocks are used to limit the extreme positions of the slider and prevent the slider from disengaging from the slide rail.

[0009] Furthermore, the clamp base is equipped with a first displacement sensor and a second displacement sensor. The first displacement sensor is used to monitor the piston rod displacement of the first telescopic cylinder, and the second displacement sensor is used to monitor the piston rod displacement of the second telescopic cylinder. The displacement sensors are set to monitor the piston rod displacement, determine whether it has extended to the correct position, and then determine whether it has completed punching.

[0010] Furthermore, the first telescopic cylinder is a hydraulic cylinder or a pneumatic cylinder, and the second telescopic cylinder is a hydraulic cylinder or a pneumatic cylinder.

[0011] Compared with the prior art, the beneficial effects of this utility model are: it can punch holes in the two side plates of the U-shaped cavity structure on the subframe of an automobile, and the punching process of the two side plates is carried out simultaneously, which improves the processing efficiency.
