Description

Technical Field

[0001] The utility model relates to the technical field of positioning fixtures, in particular to a diffusion welding positioning fixture. Background Art

[0002] Diffusion welding is a welding method that can achieve a reliable connection by applying high temperature and pressure to two different materials, causing local plastic deformation on the surfaces of the materials in contact with each other, causing mutual diffusion between atoms, and forming a diffusion layer at the interface contact.

[0003] At present, most diffusion welding production on the market uses manual hand-held positioning. The multi-layer materials are clamped with positioning clamps in advance and then placed in a furnace for high-temperature pressurization. However, manual clamping will cause large gaps between workpieces, loose clamping, and inaccurate positioning during the clamping process, resulting in displacement between workpieces during the pressurization process, resulting in a high scrap rate, low welding reliability, and low production efficiency. In addition, manual clamping is close to the high-temperature clamping plate, which is very dangerous.

[0004] Therefore, a diffusion welding positioning fixture that can adapt to different sizes was studied and used. Utility Model Content

[0031] The long splint 6 is arranged at the top inside the clamp body 2, and the top of the long splint 6 is rotatably connected to the second threaded rod 7, the top of the second threaded rod 7 passes through the top of the clamp body 2 and extends to the top of the clamp body 2, the second threaded rod 7 is connected to the top of the clamp body 2 by a thread, and the top of the second threaded rod 7 is fixed with a second knob 8, and the first knob 5 and the second knob 8 are both provided with limit components.

[0032] Two first guide rods 9 are fixedly provided on the outside of the I-shaped splint 3, and the two first guide rods 9 are respectively arranged on the front and rear sides of the first threaded rod 4. Two first guide holes 10 are provided on both sides of the clamp body 2. One end of the first guide rod 9 passes through the first guide hole 10 and extends to the outside of the clamp body 2. Two second guide rods 11 are fixedly provided on the top of the long splint 6. The two second guide rods 11 are respectively arranged on the front and rear sides of the second threaded rod 7. Two second guide holes 12 are provided on the top of the clamp body 2. One end of the second guide rod 11 passes through the second guide hole 12 and extends to the top of the clamp body 2. Limit blocks 13 are fixedly provided on one end of the first guide rod 9 and one end of the second guide rod 11.

[0033] The limiting assembly includes three limiting rods 14 arranged at the top of the two first knobs 5 and the side of the second knob 8, a limiting clamping plate 15 is fixedly provided on the inner side of the limiting rod 14, a limiting toothed disc 16 is fixedly provided at the outer end of the two first knobs 5 and the outer end of the second knob 8, the limiting clamping plate 15 passes through a tooth groove inside the limiting toothed disc 16, a T-shaped slide groove 17 is provided on both sides and the top of the clamp body 2, a T-shaped slide block 18 is provided inside the T-shaped slide groove 17, and the three T-shaped slide blocks 18 are fixedly connected to the three T-shaped slide blocks 18 respectively, a fixing rod 19 is fixedly provided inside the T-shaped slide groove 17, one end of the fixing rod 19 passes through the T-shaped slide block 18, a spring 20 is sleeved on the outer end of the fixing rod 19, and both ends of the spring 20 are fixedly connected to one end inside the T-shaped slide groove 17 and the outer side of the T-shaped slide block 18 respectively, and a handle 21 is fixedly provided on the outer side of the limiting rod 14.

[0034] Put multiple stacked materials that need to be welded into the inside of the clamp body 2, and control the rotation of the first threaded rod 4 and the second threaded rod 7 in the XYZ axis direction by rotating the two first knobs 5 and the second knob 8 respectively. The first threaded rod 4 and the second threaded rod 7 will drive the I-shaped clamp 3 and the long strip clamp 6 to clamp the material, so that the material is firmly clamped inside the clamp body 2. The clamp in the XY direction adopts an I-shaped clamp, and the clamp in the Z direction adopts a narrow and long strip style, so that it can adapt to a variety of different sizes of materials to be welded as much as possible and maintain the stability of clamping.

[0036] When the first knob 5 and the second knob 8 are turned, the handle 21 is pulled outward, the handle 21 drives the limit rod 14 to move outward, and the limit rod 14 drives the T-shaped slider 18 to compress the spring 20. At the same time, the limit rod 14 will drive the limit clamping plate 15 to leave a tooth groove on the limit toothed disk 16. After the I-shaped splint 3 and the long splint 6 clamp the material, the handle 21 is released, and the T-shaped slider 18 drives the limit rod 14 and the limit clamping plate 15 to return to their original positions under the elastic force of the spring 20, and the limit clamping plate 15 will be stuck in another tooth groove on the limit toothed disk 16. In this way, the limit assembly can limit and fix the first threaded rod 4 and the second threaded rod 7, which can prevent the first threaded rod 4 and the second threaded rod 7 from sliding, and further prevent the I-shaped splint 3 and the long splint 6 from moving, so that the clamping and fixation of the I-shaped splint 3 and the long splint 6 are more firmly.
