Description

Technical Field

[0001] This utility model relates to the field of leather punching clamp technology, specifically a universal clamp suitable for punching holes in leather. Background Technology

[0002] In mid-to-high-end vehicles, seat ventilation is a common feature. This requires perforating the leather to allow air circulation. To maintain the functionality and appearance of the perforated leather, precision is of paramount importance.

[0003] Existing punching machines lack leather securing devices; leather is secured using stickers. This requires time and expense to purchase stickers before processing, and the repeated positioning of the leather during processing is time-consuming and affects work efficiency.

[0004] Therefore, we propose to design a universal clamp suitable for punching holes in leather. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of this section, the abstract, and the title, and such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0007] A universal clamp for perforating leather includes a clamp frame, two first positioning members are fixedly connected to the end of the clamp frame, and second positioning members are fixedly connected to both sides of the end of the clamp frame near the two first positioning members.

[0008] A fixed pressure strip is provided at the top of one end of the clamp frame near the two first positioning members, and a movable pressure strip is provided at the top of the clamp frame. Positioning bolts are provided at both ends of the fixed pressure strip and the movable pressure strip. Slide rails corresponding to the movable pressure strip are provided on both sides of the top of the clamp frame.

[0009] As a preferred embodiment of the universal clamp for leather perforation described in this utility model, both the first positioning member and the second positioning member have L-shaped cross-sections. The clamp frame can be installed on the perforation machine through the first positioning member and the second positioning member, so that it is precisely positioned with the perforation machine.

[0010] As a preferred embodiment of the universal clamp for punching holes in leather described in this utility model, the positioning bolts at both ends of the fixing strip pass through the clamp frame and are threadedly connected to it. The fixing strip is fixed to the clamp frame by the positioning bolts. During installation, one end of the leather can be fixed to the clamp frame by tightening the positioning bolts.

[0011] As a preferred embodiment of the universal clamp for perforating leather described in this utility model, the outer walls of the positioning bolts at both ends of the movable pressure strip penetrate the slide rail and fit against its inner wall. The bottom of the slide rail is provided with a locking nut that is threadedly connected to it. The movable pressure strip can slide along the slide rail on the top of the clamp frame, and the positioning bolts slide in the slide rail. After reaching the corresponding size, the positioning bolts and locking nuts are tightened to fix the movable pressure strip.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention eliminates the need for stickers to fix the leather and avoids the need to repeatedly position the leather, thus reducing the time required for sticker procurement and leather positioning. Attached Figure Description

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0022] Please see Figure 1-3 This utility model provides a universal clamp suitable for punching holes in leather, including a clamp frame 1, with two first positioning members 2 fixedly connected to the end of the clamp frame 1, and second positioning members 3 fixedly connected to both sides of the end of the clamp frame 1 near the two first positioning members 2.

[0023] In this embodiment, the first positioning member 2 and the second positioning member 3 are both L-shaped in cross-section. The fixture frame 1 can be installed on the punching machine through the first positioning member 2 and the second positioning member 3, so that it is precisely positioned with the punching machine.

[0024] A fixed pressure strip 4 is provided at the top of one end of the clamp frame 1 near the two first positioning members 2, and a movable pressure strip 5 is provided at the top of the clamp frame 1. Positioning bolts 6 are provided at both ends of the fixed pressure strip 4 and the movable pressure strip 5. Slide rails 7 corresponding to the movable pressure strip 5 are provided on both sides of the top of the clamp frame 1.

[0025] The positioning bolts 6 at both ends of the fixing strip 4 pass through the clamp frame 1 and are threaded to it. The fixing strip 4 is fixed to the clamp frame 1 by the positioning bolts 6. During installation, one end of the leather can be fixed to the clamp frame 1 by tightening the positioning bolts 6.

[0026] The outer walls of the positioning bolts 6 at both ends of the movable pressure strip 5 penetrate the slide rail 7 and fit against its inner wall.
