Technical Field

[0001] The utility model relates to the technical field of spot welding machines, and particularly relates to a spot welding machine with a function of moving a spot welding gun head. Background Art

[0002] A spot welding machine is a welding device used for metal processing, mainly used to heat metal workpieces instantaneously at high temperature through a spot welding gun head, so that their surfaces melt and form a weld at the contact surface.

[0003] The Chinese patent "A spot welding machine with a function of moving a spot welding gun head" with the authorization announcement number "CN219336348U" uses a transmission disc, a threaded column, a nut and a pressing plate to limit the moving range of the spot welding gun head, so as to ensure that the spot welding gun head can weld workpieces of different models.

[0004] However, when welding workpieces of different models, it is necessary to adjust the position of the pressing plate on the transmission disc each time to adjust the moving range of the spot welding gun head. This method is too inconvenient to operate and reduces the convenience of using the spot welding machine.

[0005] Therefore, a spot welding machine with a function of moving a spot welding gun head is proposed to solve the above problems. Summary of the Utility Model

A spot welding machine with a function of moving a spot welding gun head includes: a spot welding table, both sides of the top of the spot welding table are slidably connected with clamping blocks, a spot welding gun is arranged on the top of the spot welding table, a first electric push rod is fixedly connected to the top of the spot welding gun, and an adjusting mechanism is arranged on the top of the spot welding table; wherein, the adjusting mechanism includes a lead screw rotatably connected to the inner wall of the spot welding table, a slider is threadedly connected to the surface of the lead screw, a second electric push rod is fixedly connected to the inner wall of the slider, a fixed block is fixedly connected to the telescopic end of the second electric push rod, the surface of the first electric push rod is fixedly connected to the inner wall of the fixed block, a servo motor is fixedly connected to one side of the spot welding table, an output shaft of the servo motor is fixedly connected to one end of the lead screw, and an adjusting component is arranged on the top of the spot welding table. By using the servo motor, the lead screw, the first electric push rod and the second electric push rod, the position adjustment of the spot welding gun is realized, and it is ensured that the spot welding gun can move in all directions on the spot welding table.

[0008] Preferably, the adjusting assembly includes a limiting frame fixedly connected to one side of the clamping block. A sliding cylinder is fixedly connected to one side of the limiting frame. A sliding rod is slidably connected to the inner wall of the sliding cylinder. Two blocking frames are fixedly connected to the surface of the sliding rod. A limiting block is fixedly connected to the bottom of one of the blocking frames. By using the sliding cylinder, the sliding rod, the blocking frames and the limiting block, the movement position of the spot welding gun is restricted, and the operation of adjusting the movement range of the spot welding gun is simple, which increases the accuracy of the spot welding gun moving to the welding position of the workpiece.

[0009] Preferably, a liquid storage tank is fixedly connected to the bottom of the spot welding table. A liquid pushing block is slidably connected to the inner wall of the liquid storage tank.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] During specific implementation: As Figures 1-4As shown in the figure, a spot welder with a movable spot welding gun head function includes: a spot welding table 1, clamping blocks 2 are slidably connected to both sides of the top of the spot welding table 1, a spot welding gun 4 is arranged on the top of the spot welding table 1, a first electric push rod 3 is fixedly connected to the top of the spot welding gun 4, and an adjusting mechanism 5 is arranged on the top of the spot welding table 1; among them, the adjusting mechanism 5 includes a lead screw 51 rotatably connected to the inner wall of the spot welding table 1, a slider 52 is threadedly connected to the surface of the lead screw 51, a second electric push rod 53 is fixedly connected to the inner wall of the slider 52, a fixed block 54 is fixedly connected to the telescopic end of the second electric push rod 53, the surface of the first electric push rod 3 is fixedly connected to the inner wall of the fixed block 54, a servo motor 55 is fixedly connected to one side of the spot welding table 1, an output shaft of the servo motor 55 is fixedly connected to one end of the lead screw 51, and an adjusting component 56 is arranged on the top of the spot welding table 1. The adjusting component 56 includes a limiting frame 561 fixedly connected to one side of the clamping block 2, a sliding cylinder 562 is fixedly connected to one side of the limiting frame 561, a sliding rod 563 is slidably connected to the inner wall of the sliding cylinder 562, two blocking frames 564 are fixedly connected to the surface of the sliding rod 563, a limiting block 565 is fixedly connected to the bottom of one of the blocking frames 564, one end of the sliding rod 563 is fixedly connected to a spring 5610, and the other end of the spring 5610 is fixedly connected to one end of the inner wall of the sliding cylinder 562.

[0025] A fourth electric push rod is fixedly connected to the top of the spot welding table 1, and a telescopic end of the fourth electric push rod is fixedly connected to one side of the clamping block 2.

[0026] When spot welding operation needs to be performed on a workpiece, place the workpiece on the spot welding table 1, manually turn on the fourth electric push rod, the telescopic end of the fourth electric push rod moves to drive the clamping block 2 to move, the clamping block 2 moves to drive the limiting frame 561, the sliding cylinder 562, the sliding rod 563, the blocking frame 564 and the limiting block 565 to move, so that the two clamping blocks 2 clamp and position the workpiece. Manually turn off the fourth electric push rod and turn on the servo motor 55. The output shaft of the servo motor 55 rotates to drive the lead screw 51 to rotate. The lead screw 51 rotates to drive the second electric push rod 53, the fixed block 54 and the spot welding gun 4 to move. Since the blocking frame 564 limits the moving range of the spot welding gun 4, the spot welding gun 4 moves to the position to be welded on the workpiece. Manually turn off the servo motor 55 and turn on the first electric push rod 3. The telescopic end of the first electric push rod 3 moves downward to drive the spot welding gun 4 to move downward to the position to be welded for spot welding operation. After the spot welding is completed, manually turn off the first electric push rod 3.

[0027] Such as Figure 3As shown in the figure, a liquid storage tank 566 is fixedly connected to the bottom of the spot welding table 1. A liquid pushing block 567 is slidably connected to the inner wall of the liquid storage tank 566. A corrugated hose 568 is communicated with the inner wall of the liquid storage tank 566. One end of the corrugated hose 568 is communicated with the inner wall of the sliding cylinder 562. A third electric push rod 569 is fixedly connected to the bottom of the liquid storage tank 566. The telescopic end of the third electric push rod 569 is fixedly connected to the bottom of the liquid pushing block 567. A placing rack 5612 is fixedly connected to the inner wall of the liquid storage tank 566.

[0028] It should be noted that in the above description, the first electric push rod 3, the second electric push rod 53, the spot welding gun 4, the servo motor 55, the fourth electric push rod, etc. are all devices with relatively mature applications in the prior art. The specific models can be selected according to actual needs. At the same time, the power supply of the first electric push rod 3, the second electric push rod 53, the spot welding gun 4, the servo motor 55, and the fourth electric push rod can be powered by an internal power supply or by mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0029] The two clamping blocks 2 move to clamp and position the workpiece and drive the limiting frame 561, the blocking frame 564, and the limiting block 565 to move to appropriate positions. Manually turn on the third electric push rod 569. The telescopic end of the third electric push rod 569 moves to drive the liquid pushing block 567 to move in the liquid storage tank 566, so that the hydraulic oil stored in the liquid storage tank 566 is transported to the sliding cylinder 562 through the corrugated hose 568. Excessive hydraulic oil in the sliding cylinder 562 pushes the sliding rod 563, the blocking frame 564, and the limiting block 565 to move to appropriate positions. Manually turn off the third electric push rod 569, thereby ensuring that the spot welding gun 4 can accurately move to the workpiece to be welded.

[0030] As Figure 3 As shown in the figure, a support block 5613 is fixedly connected to the rear end of the fixed block 54. The surface of the support block 5613 is slidably connected to the inner wall of the slider 52. The support block 5613 is used to support and limit the fixed block 54 to ensure the stability of the spot welding gun 4 and the first electric push rod 3 on the fixed block 54.

[0031] As Figure 3 As shown in the figure, a guide rod 5611 is fixedly connected to the inside of the spot welding table 1. The inner wall of the slider 52 is slidably connected to the surface of the guide rod 5611. The slider 52 moves on the guide rod 5611 to ensure that the slider 52 does not deviate during movement.

[0032] When the utility model is in use, place the workpiece on the spot welding table 1, manually turn on the fourth electric push rod, and the telescopic end of the fourth electric push rod moves to drive the clamping block 2, the limit frame 561, the sliding cylinder 562, the sliding rod 563, the blocking frame 564 and the limit block 565 to move, so that the two clamping blocks 2 clamp and position the workpiece. Manually turn off the fourth electric push rod and turn on the third electric push rod 569. The telescopic end of the third electric push rod 569 moves to drive the liquid pushing block 567 to move in the liquid storage tank 566, so that the hydraulic oil stored in the liquid storage tank 566 is conveyed into the sliding cylinder 562 through the corrugated hose 568. Excessive hydraulic oil in the sliding cylinder 562 pushes the sliding rod 563, the blocking frame 564 and the limit block 565 to move to a proper position. Manually turn off the third electric push rod 569 and turn on the servo motor 55. The output shaft of the servo motor 55 rotates to drive the second electric push rod 53, the fixed block 54 and the spot welding gun 4 to move through the lead screw 51. Since the blocking frame 564 limits the moving range of the spot welding gun 4, the spot welding gun 4 accurately displaces to the welding position of the workpiece. Manually turn off the servo motor 55 and turn on the first electric push rod 3. The telescopic end of the first electric push rod 3 moves downward to drive the spot welding gun 4 to move downward to the welding position for spot welding operation. After the spot welding is completed, manually turn off the first electric push rod 3.

[0033] In addition, it should be understood that although this specification is described according to the embodiments, not each embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be properly combined to form other embodiments that can be understood by those skilled in the art.
