[0020] See also Figure 1-5 As shown, the utility model relates to a welding machine fixture, which is used to clamp multiple products for friction welding processing. In the utility model, the welding fixture includes a base 1, a clamping assembly, a support assembly 3, and a pressing push block group, and the clamping assembly, the support assembly 3 and the pressing push block group are respectively arranged on the base 1. Among them, above the support assembly 3 is a product processing position 34, and the product is placed on the product processing position 34. The clamping assembly includes a positioning plate 2 and a cylinder push block assembly 4. The positioning plate 2 and the cylinder push block assembly 4 are respectively limited and clamped on both sides of the product. At the same time, the pressing push block group is arranged on both sides of the product processing position 34, and can be limited and pressed on the top of the product.

[0021] In this embodiment, the welding machine fixture is used to clamp the first product 6 and the second product 7 for friction welding processing. In this embodiment, the support assembly 3 includes a first positioning block 31, a second positioning block 32 and a third positioning block 33. The first positioning block 31 and the third positioning block 33 are arranged on both sides of the bottom plate, and the second positioning block 32 is arranged between the first positioning block 31 and the third positioning block 33. When the first product 6 and the second product 7 are placed in the product processing position 34, the first positioning block 31 and the second positioning block 32 are supported on the first product 6, and the third positioning block 33 and the second positioning block 32 are supported on the second product 7, wherein the second positioning block 32 is supported on the first product 6 and the second product 7 respectively. When the positioning plate 2 and the cylinder push block assembly 4 are limitedly clamped on both sides of the product, the first product 6 and the second product 7 are close to each other, and the junction of the first product 6 and the second product 7 is the friction welding position 35. The second positioning block 32 supports the first product 6 and the second product 7 to reduce the deformation problem caused by the friction welding pressure F1 during the friction welding process.

[0022] Furthermore, in this embodiment, the positioning plate 2 is arranged on one side of the product processing position 34, and the cylinder push block assembly 4 is arranged on the other side of the product processing position 34. The cylinder push block assembly 4 includes a push block frame 41, a cylinder part 42 and a push rod part 43. The push block frame 41 is installed on the base 1, and the cylinder part 42 and the push rod part 43 are installed on the push block frame 41, wherein the output end of the cylinder part 42 is connected to the push rod part 43. When the first product 6 and the second product 7 are placed in the product processing position 34, the cylinder part 42 drives the push rod part 43, and pushes the second product 7 through the push rod part 43, so that the second product 7 moves closer to the first product 6. Finally, the first product 6 and the second product 7 are clamped between the positioning plate 2 and the cylinder push block assembly 4.

[0023] Furthermore, the pressing push block group includes a plurality of pressing push blocks 5 , and the plurality of pressing push blocks 5 are symmetrically arranged on both sides of the product processing position 34 . Among them, the clamping push block 5 includes a clamping frame 51, a driving part 52 and a clamping part 53. The clamping frame 51 is fixedly installed on the base 1. The clamping frame 51 is provided with a slide groove 512 for the clamping part 53 to slide. The clamping part 53 can be slidably installed in the slide groove 512. The driving part 52 is installed on the clamping frame 51. The output end of the driving part 52 is connected to the clamping part 53. The driving part 52 can control the clamping part 53 to slide into or out of the slide groove 512. When the clamping part 53 slides out of the slide groove 512, the clamping part 53 will slide into the product processing position 34 to clamp and fix the first product 6 and the second product 7. After clamping, the pressure provided by the clamping part 53 can completely fasten the product to the product processing position 34, and the product will not be deformed due to the pressure during welding, thereby ensuring the size and flatness of the product after welding.

[0024] In this embodiment, the cross section of the pressing part 53 matches the slide groove 512, and a roller 531 is provided at the end of the pressing part 53. When the pressing part 53 slides out of the slide groove 512, the roller 531 slides into the product processing position 34 along with the pressing part 53 to press and fix the first product 6 and the second product 7. The roller 531 can adapt to products of different sizes, shapes and materials, and can ensure that the product maintains a stable shape and size during processing or welding, avoiding quality problems caused by uneven pressure or friction welding pressure F1, and improving the versatility and flexibility of the pressing part 53.

[0025] In this embodiment, a clamping limiter 511 is provided above the opening of the slide groove 512 of the clamping frame 51, and the clamping limiter 511 protrudes from the outer surface of the clamping frame 51. When the clamping part 53 slides out of the slide groove 512, the clamping limiter 511 presses the clamping part 53 to prevent the clamping part 53 from warping or vibrating during processing, which may cause the product to fail to be clamped.

[0026] In the present invention, a slide groove 512 is provided on the pressing frame 51 of the pressing push block group, and the pressing or unlocking operation of the product is realized by sliding the pressing part 53 out of or into the slide groove 512. When the pressing part 53 slides out of the slide groove 512, the pressing part 53 will slide into the product processing position 34 to press and fix the product, thereby fastening the product to the fixture. The pressure provided by the pressing part 53 can completely fasten the product to the product processing position 34, and the product will not be deformed due to the pressure during the friction welding process, and the size and flatness of the product after welding are also guaranteed.
