Technical Field

[0001] The utility model relates to the technical field of spot welding equipment, in particular to a high-precision spot welding machine. Background Art

[0002] The spot welder is a mechanical device that uses the principle of double-sided double-point overcurrent welding. When working, a circuit is formed between the upper and lower electrodes and the material, and an instantaneous thermal weld is formed at the two contact resistance points, thereby achieving the purpose of welding the material.

[0003] When a current spot welder is used for welding, the material is generally fixed on the spot welder, the position of the material is adjusted first, and then the spot welder is started to weld a certain part of the material. When welding is required on different parts, the spot welder must first be turned off, the position of the material is adjusted, and then the material is fixed, and then the spot welder is started for welding. The operation is cumbersome and it is not possible to flexibly weld different parts of the material.

The upper part of the moving block is rotatably connected to the screw, and the clamping plate is threadedly connected to the screw. The gear is rotatably connected to the middle of the front wall of the mounting seat, the top of the gear is meshed with the bottom of the right moving block, and the bottom of the gear is meshed with the right side of the left moving block.

The mounting seat 1 is provided with a clamping mechanism for clamping and fixing the material to be welded, and the top rear side of the mounting seat 1 is provided with a welding mechanism for welding the material.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the clamping mechanism includes a moving block 3, a clamping plate 4, a screw 5 and a gear 6. The moving blocks 3 are slidably connected to the left and right sides of the top of the mounting seat 1. The bottom of the right moving block 3 is rack-shaped, and the right side of the left moving block 3 is rack-shaped. The upper part of the moving block 3 is rotatably connected to the screw 5, and the clamping plates 4 are threadedly connected to the screw 5. The clamping plate 4 can clamp the upper and lower sides of the material. The gear 6 is rotatably connected to the middle of the front wall of the mounting seat 1. The gear 6 can drive the left moving block 3 to move when the right moving block 3 moves. The top of the gear 6 is meshed with the bottom of the right moving block 3, and the bottom of the gear 6 is meshed with the right side of the left moving block 3.

[0024] like Figure 1 and Figure 5As shown, the welding mechanism includes a bidirectional screw 7, a mounting block 8, a limiting rod 9, a mounting plate 10, an electric telescopic rod 11, a handle 12, a lifting block 13, a lower welding electrode 14 and an upper welding electrode 15. The mounting block 8 is slidably connected to the rear side of the top of the mounting seat 1, and the bidirectional screw 7 is rotatably connected between the left and right sides of the lower rear side of the mounting seat 1. The left end of the bidirectional screw 7 is in the shape of a gear 6, which is convenient for people to rotate the bidirectional screw 7. The bidirectional screw 7 is threadedly connected to the lower part of the mounting block 8. The limiting rod 9 is fixedly connected between the left and right sides of the middle part of the rear side of the mounting seat 1, and the limiting rod 9 is slidably connected to the middle of the mounting block 8. A mounting plate 10 is slidably connected to the middle of the mounting block 8, a lower welding electrode 14 is fixedly connected to the top front side of the mounting plate 10, a lifting block 13 is slidably connected to the upper portion of the mounting block 8, an upper welding electrode 15 is connected to the bottom front side of the lifting block 13, an electric telescopic rod 11 is connected to the top rear side of the mounting plate 10, the electric telescopic rod 11 can move the upper welding electrode 15 up and down, the top end of the electric telescopic rod 11 is connected to the bottom rear side of the lifting block 13, a handle 12 is fixedly connected to the top rear side of the mounting plate 10, the handle 12 is located on the rear side of the electric telescopic rod 11, and the upper part of the handle 12 is slidably connected to the rear of the lifting block 13.

[0025] When people need to weld the material, first place the material in the middle of the mounting seat 1, and then push the moving block 3 on the right side to the left, thereby driving the gear 6 to rotate counterclockwise, and then driving the moving block 3 on the left side to move to the right, and the moving blocks 3 on the left and right sides move to the middle, thereby driving the clamping plates 4 and the screw rod 5 on both sides to move to the middle. When the moving blocks 3 on the left and right sides clamp the left and right sides of the middle material, the top of the screw rod 5 is made of rubber material, which is convenient for people to rotate the screw rod 5. By rotating the screw rod 5, the screw rod 5 drives the clamping plate 4 to move downward, thereby clamping the material up and down. At this time, the bottom of the material contacts the lower welding electrode 14, and then people start the electric telescopic rod 11, and the electric telescopic rod 11 drives the lifting block 13 to move downward, thereby driving the upper welding electrode 15 to move downward. When the upper welding electrode 15 contacts the top of the material, the electric telescopic rod 11 is closed, and the material can be welded. During the welding process, the mounting block 8 is driven to move left and right by rotating the bidirectional screw 7, thereby driving the mounting plate 10 and The lifting block 13 moves left and right, thereby driving the lower welding electrode 14 and the upper welding electrode 15 to move left and right, and then by pulling the handle 12, the mounting plate 10 and the lifting block 13 move forward and backward, thereby driving the lower welding electrode 14 and the upper welding electrode 15 to move forward and backward, thereby the welding head can be adjusted in multiple directions, and various parts of the material can be welded quickly and conveniently. When welding is completed, people start the electric telescopic rod 11, and the electric telescopic rod 11 drives the lifting block 13 to move upward, thereby driving the upper welding electrode 15 to move upward. When the upper welding electrode 15 is reset, the electric telescopic rod 11 is turned off. At this time, people rotate the screw rod 5 in the opposite direction, and the screw rod 5 drives the clamping plate 4 to move upward. The clamping plate 4 no longer clamps the material up and down. First, fix the material with a tool, and then push the moving block 3 on the right side to the right, thereby driving the gear 6 to rotate clockwise, and then driving the moving block 3 on the left side to move to the left. The moving blocks 3 on the left and right sides no longer clamp the left and right sides of the middle material. At this time, people take away the welded material.

[0027] On the basis of Example 1, Figure 1 and Figure 2 As shown, it also includes universal wheels 2, and four universal wheels 2 are rotatably connected to the bottom of the mounting base 1.

[0028] In order to shorten the distance that the welding materials need to be transported, people push the mounting base 1. Since the bottom of the mounting base 1 is connected with a universal wheel 2, the spot welding machine can be pushed to the side of the material pile, so as to facilitate welding of the materials.
