Description

Technical Field

[0001] The utility model relates to the technical field of electric contact processing and welding, in particular to a welding device for an electric contact processing procedure. Background Art

[0002] The contact is one of the key components of the switchgear. According to the structure and working characteristics, it can be divided into three categories: breakable contact, sliding contact and fixed contact. The main performance and life of the switchgear depend to a large extent on the quality of the contact material. The contact material is usually required to have good conductivity, low contact resistance, high resistance to fusion welding, high resistance to arc erosion and resistance to material transfer. For vacuum contact materials, it is also required to have a small cutoff value, high pressure resistance and high breaking capacity. The microstructure of the contact material has an important influence on its macroscopic performance. The electrical properties of the contact material, such as resistance to fusion welding, arc ablation resistance and pressure resistance, are not only related to the composition of the contact material, but also to the size of the grains of the constituent materials.

[0003] After extensive searching, it was found that: China Utility Model Patent Column: Publication No. CN217316592U is an electric contact welding fixture, which can quickly clamp the electric contact to facilitate welding operations. At the same time, the shape of the clamp can be changed according to the shape of the electric contact to facilitate clamping. Although this patent can achieve the clamping and fixing of the electric contact, the shape of the electric contact is complex, and the processing operations after clamping are often not on the same plane. Therefore, it is necessary to rotate the angle during operation to adapt to processing in different positions. The device cannot rotate and needs to be disassembled and reinstalled before processing. Therefore, there are certain disadvantages in actual use. Utility Model Content

After fixation, the cushion block 4 is moved to the inside of the rotating seat 3, so that the electric contact is only clamped by the first slide bar 12 and the second slide bar 19, so that it is in a suspended state, thereby facilitating the subsequent rotation operation of the electric contact. At the same time, the rotating seat 3 is rotatably installed on the base 1, so that the electric contact can be rotated in the horizontal direction. The welding gun during the welding process can be placed by the set support rod 2, avoiding the welding gun being placed directly on the workbench or other positions during the welding process, which may cause difficulty in taking or damage to the welding gun.

[0027] Furthermore, a receiving groove is provided on the surface of the rotating seat 3 relative to the position of the cushion block 4, and an electric telescopic rod 5 is fixedly installed inside the receiving groove. The output port of the electric telescopic rod 5 is fixedly connected to the cushion block 4, and the cushion block 4 uses the electric telescopic rod 5 to achieve vertical movement. Therefore, after the electric contact is clamped by the first sliding bar 12 and the second sliding bar 19, the electric telescopic rod 5 can drive the cushion block 4 to move into the receiving groove, thereby avoiding the existence of the cushion block 4 affecting the rotation of the electric contact.

[0028] Furthermore, the internal rotation of the rotating seat 3 is connected with a screw rod 10, and the screw rod 10 is provided with two sections of opposite threads with its midpoint as the dividing line. The first slide bar 12 and the second slide bar 19 are respectively threadedly connected to the two ends of the screw rod 10, and the internal part of the rotating seat 3 is fixedly installed with a second motor 9, and the output shaft port of the second motor 9 is fixedly connected to the screw rod 10. When the second motor 9 is started, the second motor 9 drives the screw rod 10 to rotate, and the screw rod 10 drives the first slide bar 12 and the second slide bar 19 to move in relative directions, so that the electric contacts can be clamped.

[0029] Furthermore, the surfaces of the first slide bar 12 and the second slide bar 19 are respectively rotatably penetrated by the first rotating shaft 13 and the second rotating shaft 16, and the ends of the first rotating shaft 13 and the second rotating shaft 16 close to each other are fixedly installed with clamping blocks 15, and the ends of the two clamping blocks 15 close to each other are provided with clamping grooves, and the inside of the clamping grooves is fixedly installed with rubber pads 14, and the side wall of the first slide bar 12 is fixedly installed with the third motor 11, and the output shaft port of the third motor 11 is fixedly connected to the first rotating shaft 13, and the first rotating shaft 13 and the second rotating shaft are rotatably arranged on the first slide bar 12 and the second slide bar 19. 16, the clamping blocks 15 at the ends of the first rotating shaft 13 and the second rotating shaft 16 are used to clamp the electric contacts, so the first rotating shaft 13 and the second rotating shaft 16 can be used to rotate the electric contacts after clamping. Specifically, the third motor 11 is used to drive the first rotating shaft 13 to rotate, the first rotating shaft 13 drives the clamping blocks 15 at the ends to rotate, the clamping blocks 15 drive the electric contacts to rotate, and the second rotating shaft 16 and the clamping blocks 15 at the ends have no power drive, so they rotate directly following the rotation of the electric contacts, thereby facilitating the vertical rotation of the electric contacts by 360 degrees.

[0030] Furthermore, a round block 18 is fixedly installed at one end of the second rotating shaft 16 away from the clamping block 15, a torsion spring 17 is sleeved on the surface of the second rotating shaft 16, a circular groove is opened on the surface of the second sliding rod 19, the torsion spring 17 and the round block 18 are both arranged inside the circular groove, and the two ends of the torsion spring 17 are fixedly connected to the round block 18 and the circular groove respectively. The torsion spring 17 is arranged on the second rotating shaft 16, so when the clamping block 15 and the second rotating shaft 16 are not subjected to force, the torsion spring 17 can be used to make the clamping block 15 automatically rotate to a horizontal state and then stop, so as to facilitate the removal of the electric contact, and the subsequent clamping and fixing operation of the electric contact can be realized without manually rotating the second rotating shaft 16.

[0031] Furthermore, a first motor 8 is fixedly installed inside the base 1, and an output shaft port of the first motor 8 is fixedly connected to the rotating base 3. By setting the first motor 8, the rotating base 3 can be driven to rotate, thereby realizing a 360-degree rotation in the horizontal direction.

[0032] Furthermore, an embedding groove 7 matching the size and shape of the electric contact is provided at the center of the surface of the pad 4, and grooves 6 matching the size of the clamping block 15 are provided on the surface of the pad 4 at positions on both sides of the embedding groove 7. The embedding groove 7 provided on the pad 4 can place the electric contact directly in the embedding groove 7, thereby facilitating the positioning of the electric contact, and then the two clamping blocks 15 are brought close to each other, and the two clamping blocks 15 just enter the two grooves 6 to clamp the electric contact, and then the pad 4 is moved downward to disengage the electric contact from the embedding groove 7.

[0033] In summary, the pad 4 adapted to the contact is installed on the rotating seat 3. During the welding processing clamping process, the pad 4 is first moved out of the top of the rotating seat 3, and the electric contact is placed on the pad 4. Then the first slide bar 12 and the second slide bar 19 are brought close to each other, so that the first slide bar 12 and the second slide bar 19 clamp and fix the electric contact. After fixing, the pad 4 is moved to the inside of the rotating seat 3, so that the electric contact is only clamped by the first slide bar 12 and the second slide bar 19, so that it is in a suspended state, thereby facilitating the subsequent rotation operation of the electric contact. At the same time, the rotating seat 3 is rotatably installed on the base 1, so that the electric contact can be rotated in the horizontal direction. The support rod 2 can be set In order to place the welding gun during the welding process, it is avoided that the welding gun is directly placed on the workbench or other positions during the welding process, which may cause difficulty in taking or damage to the welding gun. The pad 4 uses the electric telescopic rod 5 to move in the vertical direction, so that after the electric contact is clamped by the first slide bar 12 and the second slide bar 19, the electric telescopic rod 5 can drive the pad 4 to move to the inside of the accommodating groove to avoid the existence of the pad 4 affecting the rotation of the electric contact. The second motor 9 is started, and the second motor 9 drives the screw rod 10 to rotate. The screw rod 10 drives the first slide bar 12 and the second slide bar 19 to move in relative directions, so that the electric contact can be clamped. The first rotating shaft 13 and the second rotating shaft 16 are automatically set, and the clamping blocks 15 at the ends of the first rotating shaft 13 and the second rotating shaft 16 are used to clamp the electric contact. Therefore, the first rotating shaft 13 and the second rotating shaft 16 can be used to rotate the clamped and fixed electric contact. Specifically, the third motor 11 drives the first rotating shaft 13 to rotate, and the first rotating shaft 13 drives the clamping block 15 at the end to rotate, and the clamping block 15 drives the electric contact to rotate. The second rotating shaft 16 and the clamping block 15 at the end have no power drive, so they rotate directly following the rotation of the electric contact, thereby facilitating the vertical rotation of the electric contact by 360 degrees. The second rotating shaft 16 is provided with a torsion spring 17, so between the clamping block 15 and the first rotating shaft 16, the torsion spring 17 can be used to rotate the electric contact. When the second rotating shaft 16 is not subjected to force, the torsion spring 17 can be used to automatically rotate the clamping block 15 to a horizontal state and then to remain stationary, so that when the electric contact is removed, the subsequent clamping and fixing operation of the electric contact can be achieved without manually rotating the second rotating shaft 16. By setting the first motor 8, the rotating seat 3 can be driven to rotate, so that a 360-degree rotation in the horizontal direction can be achieved. The embedding groove 7 set on the cushion block 4 can place the electric contact directly in the embedding groove 7, so as to facilitate the positioning of the electric contact. Then the two clamping blocks 15 are close to each other, and the two clamping blocks 15 just enter the two grooves 6 to clamp the electric contact. Then the cushion block 4 is moved down to disengage the electric contact from the embedding groove 7.
