[0008] As a further description of the above technical solution:

[0009] A blind hole groove is formed on the top surface of the fixing block, the fixing block is slidably connected in the blind hole groove, and the blind hole groove is connected to the arc-shaped positioning groove.

[0010] As a further description of the above technical solution:

[0011] The inner wall of the arc-shaped positioning groove and the inner wall of the arc-shaped positioning hole are both provided with anti-slip pads.

[0012] As a further description of the above technical solution:

[0013] The telescopic device is a cylinder.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0015] In the utility model, the expansion and contraction of the expander drives the wedge block to act on the sliding block, so that the sliding block slides in the fixed block. The pipe fitting can be quickly fixed between the arc-shaped positioning groove and the arc-shaped positioning hole, and can also be quickly disassembled, so that the entire workpiece clamp has a quick-disassembly structure while being able to protect the pipe fitting and avoid crushing of the pipe fitting, thereby greatly improving the processing yield.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 The utility model provides a technical solution: a workpiece fixture with a quick-release structure, comprising a platform plate 1, a fixed block 2, a slider 3, a telescope 4 and a wedge 5, wherein the fixed block 2 is mounted on the platform plate 1, an arc-shaped positioning groove 6 is provided on the top surface of the fixed block 2, the slider 3 is slidably connected in the fixed block 2, an arc-shaped positioning hole 7 is provided on the slider 3, the telescope 4 is mounted on the fixed block 2, the wedge 5 is mounted on the telescopic end of the telescope 4, the wedge 5 is inserted into the slider 3 and drives the slider 3 to slide;

[0023] The slide block 3 is provided with a guide groove 8 matching the wedge block 5, and the inclined surface of the wedge block 5 abuts against the inclined surface of the guide groove 8, so as to facilitate the directional sliding of the fixed block 2;

[0024] A blind hole groove 9 is formed on the top surface of the fixing block 2, and the fixing block 2 is slidably connected in the blind hole groove 9. The blind hole groove 9 is connected to the arc-shaped positioning groove 6, so as to facilitate the directional sliding of the fixing block 2.

[0025] The inner wall of the arc-shaped positioning groove 6 and the inner wall of the arc-shaped positioning hole 7 are both provided with anti-slip pads 10, which have a protective effect on the pipe fittings and also ensure that the pipe fittings are firmly positioned;

[0026] The telescopic device 4 is a cylinder, which is convenient for rapid telescopic adjustment.

[0027] Working principle: First, the expansion and contraction of the expander 4 drives the wedge block 5 to act on the slider 3, that is, the inclined surface of the wedge block 5 is against the inclined surface of the guide groove 8, so that the slider 3 slides in the blind hole groove 9 of the fixed block 2, and secondly, the pipe fitting passes through the arc-shaped positioning groove 6 and the arc-shaped positioning hole 7, and the pipe fitting can be quickly fixed between the arc-shaped positioning groove 6 and the arc-shaped positioning hole 7. During the process, the anti-slip pad 10 protects the pipe fitting and also ensures that the pipe fitting is firmly positioned. Finally, similarly, the pipe fitting can also be quickly disassembled, so that the entire workpiece fixture can protect the pipe fitting while having a quick-disassembly structure to avoid crushing of the pipe fitting, thereby greatly improving the processing yield.
