[0023] EMBODIMENT

[0024] As Figure 1 shown, the utility model provides a kind of diamond wire butt welding machine of rotatable angle, including frame 1 and welding system, and welding system includes welding power supply and two welding heads, and welding head is electrically connected with welding power supply.Welding power supply provides stable current output, for heating in resistance welding process.Welding head transmits current to the butt joint part of diamond wire, realizes resistance heating.In the welding of two diamond wires, make current pass through the contact part of diamond wire.Due to the existence of resistance, contact part will generate heat.Heat causes the contact part of diamond wire to melt, under the action of pressure, two ends of molten metal fusion together, form butt joint.After power off, fusion site is cooled under pressure retention, form solid weld (welding system is prior art, again do not repeat, and welding system is not drawn in the figure).

[0025] As Figure 1As shown, this embodiment further includes an angle adjustment mechanism mounted on the frame 1. The angle adjustment mechanism includes two first gears 2 rotatably mounted on the frame 1, the two first gears 2 meshing with each other, a second gear 201 rotatably mounted on the frame 1, the second gear 201 meshing with one of the first gears 2, and a handle 202 fixedly mounted on the second gear 201. The handle 202 drives the second gear 201 to rotate, and the rotating second gear 201 drives the meshing first gear 2 to rotate as well. Since the two first gears 2 mesh with each other, the two first gears 2 can rotate synchronously and in opposite directions.

[0026] like Figure 1 As shown, in this embodiment, the angle adjustment mechanism is equipped with a fixing mechanism, which includes a positioning block 3 and a displacement block 301. The positioning block 3 is fixedly mounted on one of the first gears 2, and the displacement block 301 is slidably mounted on the other first gear 2. A connecting base 302 is fixedly mounted on the first gear 2 on which the displacement block 301 is mounted. A push rod motor 303 is fixedly mounted on the connecting base 302, and the output shaft of the push rod motor 303 is fixedly connected to the displacement block 301. The two diamond wires to be welded are fixed to the positioning block 3 and the displacement block 301 respectively. By rotating the two first gears 2, the positioning block 3 and the displacement block 301 can be driven to rotate, thereby changing the angle between the positioning block 3 and the displacement block 301, thereby adjusting the welding angle of the two diamond wires. When the contact portion of the diamond wires melts under the action of heat, the push rod motor 303 can drive the displacement block 301 to move, thereby driving the diamond wires fixed to the displacement block 301 to move, causing the two diamond wires to be squeezed and fused.

[0027] like Figures 2-4As shown, the positioning block 3 and the displacement block 301 in the embodiment are both provided with a variable-diameter clamping mechanism. The angle adjusting mechanism drives the positioning block 3 and the displacement block 301 to rotate, and the variable-diameter clamping mechanism positions and fixes the axes of the two diamond wires with different diameters. The variable-diameter clamping mechanism comprises a mounting cavity 4 arranged in the positioning block 3 and the displacement block 301.

The connecting rods 406 are rotatably connected with the driving plates 404. The other ends of the connecting rods 406 are rotatably connected with the driving plates 404. When the diamond wires are installed, the two diamond wires are respectively arranged in the two reference tubes 401. Then, the connecting rods 406 are driven to rotate by the rotating drum 405. The rotating connecting rods 406 can push or pull the driving plates 404. The rotating drum 405 can drive the plurality of driving plates 404 to contract or expand by rotating in different directions.

When the plurality of clamping plates 403 contract, the plurality of clamping plates 403 can uniformly press the circumferential direction of the diamond wires and move the diamond wires to the coaxial position with the reference tube 401. The diamond wires can be fixed by the friction force between the clamping plates 403 and the diamond wires, so as to ensure the coaxiality of the two diamond wires. By uniformly pressing the diamond wires in the circumferential direction, the different degrees of axial deviation of the two diamond wires caused by different forces can be prevented, so as to ensure the coaxiality of the two diamond wires during welding.

[0028] Further, the plurality of slide rods 402 are arranged in two rows. The two rows of slide rods 402 are respectively fixedly connected with the two ends of the clamping plate 403. The contact surface of the clamping plate 403 with the diamond wire is provided with anti-skid lines. The clamping plate 403 is elastic. The two rows of slide rods 402 can exert pressure on the two sides of the clamping plate 403. The clamping plate 403 can be elastically deformed. The clamping plate 403 can be wrapped on the diamond wire under the pressure of the slide rods 402, so as to increase the contact area between the clamping plate 403 and the diamond wire, increase the clamping force of the clamping plate 403 on the diamond wire, and improve the uniformity of the force of the diamond wire.

The transmission rod 412 is driven to rotate by rotating the pressing rod 411, the connecting rod 409 is driven to move downward by the rotating transmission rod 412, and the rack 408 is driven to move downward, so that the rotating drum 405 is driven to rotate by the rack 408, and the plurality of clamping plates 403 are driven to contract or expand, and a damping pad is arranged at the connecting position of the pressing rod 411 and the support plate 410 to prevent the clamping plates 403 from loosening.

[0031] Then the current passes through the contact part of the diamond wire. Due to the existence of resistance, heat is generated in the contact part. The heat causes the contact part of the diamond wire to melt, the displacement block 301 is driven to move by the push rod motor 303, and the two ends of the melted metal are fused together under the action of pressure to form a butt joint. After power-off, the welded part cools under the pressure to form a firm welding point.
