[0003] Sheet metal parts in some specific application scenarios, such as the outer shell or internal structural parts of electronic and electrical equipment, may need to be designed into different shapes according to specific functional requirements. Most of the related technologies use clamps to clamp and fix the sheet metal parts, and the clamps are rotatably connected to the slide. When dealing with sheet metal parts of different sizes, shapes or types, their adaptability is poor. When it is necessary to change the processing object or adjust the processing method, it cannot be achieved directly by disassembling the splint, which limits the flexibility of the production process, and when the clamping surface of the splint is worn, damaged or needs to be cleaned, maintenance will be very difficult. Therefore, those skilled in the art provide a workpiece fixture for sheet metal processing and production to solve the problems raised in the above background technology. Utility Model Content

Detailed Description of the Embodiments

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figure 1 , Figure 2 and Figure 5 , the present invention provides a technical solution:

[0028] A workpiece fixture for sheet metal part processing and production, comprising:

[0029] Mounting plate 1, on which a number of threaded holes 2 are provided, and a servo electric cylinder 3 is installed on the mounting plate 1;

[0030] A supporting plate 4, a connecting supporting rod 5 is welded between the supporting plate 4 and the mounting plate 1, a moving mechanism is installed on the supporting plate 4, and the servo electric cylinder 3 is connected to the moving mechanism; and:

[0031] Two movable plates 6, one end of the two movable plates 6 is connected to the movable mechanism, and the other end of the two movable plates 6 is connected to the clamp through the mounting mechanism. The mounting mechanism includes a fixing bolt 7 and two trapezoidal blocks 8. The two trapezoidal blocks 8 are fixedly welded on one side of the clamp. One end of the two movable plates 6 is provided with a clamping groove 9 for the two trapezoidal blocks 8 to be engaged. The fixing bolt 7 fixes the two trapezoidal blocks 8 to the lower end of the movable plate 6.

[0032] In the above embodiment, when installing the workpiece fixture, the mounting bolts are used to connect with the threaded holes 2, and the mounting plate 1 is installed and fixed on the sheet metal processing table. Then the fixture is installed on one end of the movable plate 6, and the two trapezoidal blocks 8 are engaged in the engagement grooves 9. Then, the two trapezoidal blocks 8 are fixedly installed on the lower end of the movable plate 6 using the fixing bolts 7, so that the fixture can be replaced to clamp different sheet metal parts. When controlling the clamping of the sheet metal parts, the servo electric cylinder 3 drives the two movable plates 6 to move by moving, thereby adjusting the distance between the fixtures to clamp and fix the sheet metal parts. Sheet metal parts of different sizes can be clamped and fixed.

[0033] Specifically, the moving mechanism includes two groups of support blocks 10, the two groups of support blocks 10 are fixedly welded on both sides of the support plate 4, and the side plates 11 are fixedly welded on one side of the two groups of support blocks 10. A first moving groove 13 for sliding connection of the first moving block 12 is opened between the two side plates 11, and a second moving groove 15 for sliding connection of the second moving block 14 is opened on the two groups of support blocks 10. The first moving block 12 and the second moving block 14 are connected to one end of the moving plate 6 through a connecting component, and the output end of the servo electric cylinder 3 is connected to the first moving block 12. The first moving groove 13 and the second moving groove 15 are convex grooves, and the first moving block 12 and the second moving block 14 are convex blocks. The convex grooves and the convex blocks can limit the first moving block 12 and the second moving block 14 when they move in the first moving groove 13 and the second moving groove 15.

[0034] The servo electric cylinder 3 pushes the first moving block 12 to move in the first moving groove 13. Since the connecting assembly includes two groups of connecting plates 16, one end of the two groups of connecting plates 16 is rotatably connected to both sides of the first moving block 12 through the first rotating rod 17, and the other end of the two groups of connecting plates 16 is rotatably connected to the second moving block 14 through the second rotating rod 18, and the other end of the second rotating rod 18 is fixedly connected to the moving plate 6. Therefore, the first moving block 12 can drive the second moving block 14 to move in the second moving groove 15 through the connecting plate 16, thereby driving the adjusting moving plate 6 to move to clamp the sheet metal.

[0035] Furthermore, the fixture includes a clamping plate 19 and a first connecting block 20. The first connecting block 20 is fixedly installed on one side of the clamping plate 19. The side of the first connecting block 20 facing away from the clamping plate 19 is connected to two trapezoidal blocks 8. A first rubber layer 21 is provided on the side of the clamping plate 19 facing away from the first connecting block 20.

[0036] The clamping plate 19 can clamp and fix the sheet metal part. Through the setting of the first rubber layer 21, the clamping effect of the clamping plate 19 can be increased.

[0037] Embodiment 2

[0038] Reference Figure 3-Figure 4 , the difference from Embodiment 1 lies in the different fixture, which is as follows:

[0039] The fixture includes a U-shaped clamping plate 22 and a second connecting block 23. The second connecting block 23 is fixedly installed on one side of the U-shaped clamping plate 22. The side of the second connecting block 23 facing away from the U-shaped clamping plate 22 is connected to two trapezoidal blocks 8. A second rubber layer 24 is provided at one end of the U-shaped clamping plate 22.

[0040] The U-shaped clamping plate 22 can clamp and fix the sheet metal part, and can clamp and fix different sheet metal parts that the clamping plate 19 cannot clamp. Through the setting of the second rubber layer 24, the clamping effect at the lower end of the U-shaped clamping plate 22 can be increased.

[0041] Two triangular blocks 25 are provided at the lower end of the second connecting block 23, and the two triangular blocks 25 are fixedly installed at one end of the moving plate 6.

[0042] Through the setting of the triangular blocks 25, the second connecting block 23 can be supported, and the connection and support effect of the second connecting block 23 can be increased.

[0043] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
