[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0032] Example 1: Refer to Figures 1-7 As shown, this utility model provides a machining fixture for thin-walled parts, comprising:

[0033] Base plate 1;

[0034] The first support block 2 is arranged parallel to the base plate 1. The side of the first support block 2 away from the base plate 1 is machined with a first arc surface 21 and a first positioning surface 22 located on one side of the first arc surface 21. Multiple first machining clearance grooves 23 and first pin holes 24 are opened on the first arc surface 21.

[0035] The second support block 3 is arranged parallel to the base plate 1. One end of the second support block 3 is coaxially connected to one end of the first support block 2. The side of the second support block 3 away from the base plate 1 is machined with a second arc surface 31 and a second positioning surface 32 located on one side of the second arc surface 31. Multiple second machining clearance grooves 33 and second pin holes 34 are opened on the second arc surface 31.

[0036] The first pin 4 is provided in multiple forms and is respectively inserted into the first pin hole 24 and the second pin hole 34;

[0037] Magnetic component, used to press the part onto the first arc surface 21 and the second arc surface 31.

[0038] Specifically, the first support block 2 and the second support block 3 are profiled parts. The top of the first support block 2 and the second support block 3 are respectively machined with a first arc surface 21 and a second arc surface 31 corresponding to the shape of the part. The top of the first support block 2 and the second support block 3 are also machined with a first positioning surface 22 and a second positioning surface 32. When the first support block 2 and the second support block 3 are installed on the base plate 1, the first arc surface 21 and the second arc surface 31 are joined together to form an arc-shaped support surface for supporting the part. The first positioning surface 22 and the second positioning surface 32 also form a positioning surface for positioning the part. The positioning of the part is achieved by multiple first pins 4 that can be inserted into the first support block 2 and the second support block 3.

[0039] Specifically, after the part is positioned, it is clamped onto the two support blocks by magnetic components. Furthermore, the part can be further clamped and fixed by tightening fasteners on the first support block 2 and the second support block 3 to ensure that the part will not shift during processing and to guarantee processing accuracy.

[0040] It is conceivable that the first support block 2 and the second support block 3 are assembled to form a support mold for supporting the parts. Compared with the structure of integral processing, this split structural design reduces the length of each part, thus reducing the deformation of the support blocks during processing and helping to ensure the final dimensional accuracy of the product. Furthermore, it is conceivable that since there are various types of this thin-walled product with similar overall shapes and structures, and the structure of the section corresponding to the first support block 2 is the same, with only some variations in slots and holes in the section corresponding to the second support block 3, the split design of the first support block 2 and the second support block 3 allows for the replacement of only the second support block 3 when producing different parts, greatly reducing the design and processing costs of tooling.

[0041] Specifically, this machining fixture is used in conjunction with laser processing equipment. The first support block 2 and the second support block 3 are provided with machining clearance grooves that correspond to the slots to be machined on the parts. The laser processing equipment can process the predetermined slot structure on the semi-finished parts fixed to the fixture, and also transfer the positioning reference of the parts to the fixture, which makes it convenient for operators to adjust the machine and helps to improve processing efficiency.

[0042] This utility model discloses a machining fixture for thin-walled parts. Based on the specific shape of the part, a support block structure is designed to support it, providing uniform and stable support, reducing deformation during machining, and improving machining accuracy. Furthermore, the split design of the support block structure reduces machining deformation during processing, further enhancing machining accuracy. The fixture's versatility and economy are also improved by allowing individual support block replacements. Precise positioning of the part on the fixture is achieved by setting positioning surfaces and pins on the support block structure, while stable clamping of the part is achieved through the cooperation of strong magnets and fasteners, simplifying clamping and positioning and improving machining efficiency. The entire machining fixture has a simple structure, is easy to operate and maintain, and has high practicality.

[0043] Reference Figure 1 and Figure 2 As shown, further, it includes a mounting bracket 5, and multiple mounting brackets 5 are provided. The multiple mounting brackets 5 are respectively connected to the side of the base plate 1 away from the first support block 2 / second support block 3 by fasteners. The mounting bracket 5 is used to connect with the processing table of the processing equipment.

[0044] Reference Figure 3 , Figure 4 and Figure 5 As shown, the first support block 2 has multiple first bolt holes 25 on the side near the base plate 1, and the second support block 3 has multiple second bolt holes 35 on the side near the base plate. The first support block 2 and the second support block 3 are connected to the base plate 1 by bolts at the first bolt holes 25 and the second bolt holes 35 respectively.

[0045] Furthermore, a plurality of first fastening holes 26 are provided on the first arc surface 21, and a plurality of second fastening holes 36 are provided on the second arc surface 31. Specifically, the first fastening holes 26 and the second fastening holes 36 are used to screw screws to fasten the parts; the number and position of the first fastening holes 26 and the second fastening holes 36 can be set according to the specific size of the parts to ensure that the force is evenly distributed when fastening the parts 8.

[0046] Furthermore, the first support block 2 is provided with multiple third pin holes 27, the second support block 3 is provided with multiple fourth pin holes 37, and the base plate 1 is provided with multiple positioning holes 11 corresponding to the positions of each third pin hole 27 and fourth pin hole 37.

[0047] Furthermore, it includes a second pin 6, and multiple second pins 6 are provided. The multiple second pins 6 are respectively inserted into the third pin hole 27 and the fourth pin hole 37 and extend to the corresponding positioning hole 11.

[0048] Furthermore, one end of the first support block 2 is provided with at least one fifth pin hole 28, and one end of the second support block 3 is provided with a sixth pin hole 38 corresponding to the position of each fifth pin hole 28. One end of the first support block 2 and the second support block 3 are connected together at the corresponding fifth pin hole 28 and sixth pin hole 38 by a third pin 7. Specifically, when installing the first support block 2 and the second support block 3, the two support blocks are first connected together by the third pin 7, then the first support block 2 and the second support block 3 are fixed to the predetermined position of the base plate 1 by the second pin, and finally the two support blocks are fastened to the base plate 1 by bolts.

[0049] Furthermore, a first groove is provided between the first positioning surface 22 and the first arc surface 21, and a second groove is provided between the second positioning surface 32 and the second arc surface 31.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
