Description

[0002] Mirror thin plates are widely used in automobile manufacturing, electronic product manufacturing, furniture manufacturing and other fields. Their surface finish and appearance quality play a vital role in the quality and aesthetics of the final product. Traditional welding methods often lead to welding marks, oxidation, deformation and other problems on mirror thin plates, seriously affecting the appearance and performance of the product.

[0003] In order to solve this problem, people began to research and develop handheld welding equipment suitable for mirror thin plates. This equipment needs to have certain welding accuracy, stability and control capabilities to ensure reliable welding connections while maintaining the surface quality of the mirror thin plates. When traditional handheld welding equipment is welding on mirror thin plates, the welding speed is limited due to the need to manually control the position and speed of the welding gun, and the welding head of the welding equipment stays on the mirror thin plate for different lengths of time. When the welding head stays at the welding point of the mirror thin plate for too long, welding marks are left at the welding point of the mirror thin plate, which seriously affects the appearance and quality of the product, thereby reducing the working efficiency of the equipment.

[0018] (1) In the present invention, the frame drives the welding gun to move in a reciprocating trajectory through the meshing of the teeth of the half gear and the frame.

[0020] (3) In the present invention, the teeth of circular gear 1 and circular gear 2 are meshed with each other, so that when the synchronous frame rotates, the synchronous frame drives the two sets of rotating shafts 1 to rotate through the limit block, so that the two sets of rotating shafts 1 respectively drive the half gears to mesh with the frame, thereby improving the stability of the reciprocating motion of the welding gun.

In addition, since the operator does not need to exert too much force to move the welding gun, it is easy to maintain the stability and consistency of the welding gun during the welding process, which helps to reduce the jitter and shaking during the welding process, improve the welding quality and the uniformity of the weld, and reduce the force that the operator needs to exert, effectively reducing the fatigue of the operator.

The upper and lower inner walls of the frame 523 are provided with teeth adapted to the half gear 522. The half gear 522 and the frame 523 are gradually enlarged in equal proportion and are provided with three groups. One of the three groups of half gears 522 and the frame 523 is meshed with the teeth at this moment.

At this moment, the bevel gear two 663 and the bevel gear one 662 are meshed through the teeth, so that the bevel gear one 662 drives the power-assisting wheel 664 to rotate through the rotating shaft five 661, so that the power-assisting wheel 664 drives the welding gun 1 to move, and because the operator does not need to exert too much force to move the welding gun 1, it is easy to maintain the stability and consistency of the welding gun 1 during welding, which helps to reduce jitter and shaking during welding and improve the welding quality and uniformity of the weld.

[0066] Example 6

[0067] like Figure 3 and Figure 8 As shown, on the basis of Example 1, a pulling assembly 650 is sleeved on the outer side of the second rotating shaft 644, and the pulling assembly 650 includes a pulling frame 651, which is sleeved on the outer side of the second rotating shaft 644, and a telescopic rod 652 is fixedly installed on the top of the pulling frame 651, and a spring 653 is sleeved on the outer side of the telescopic rod 652, and a fixed plate 654 is fixedly installed on the top of the telescopic rod 652, and the fixed plate 654 is fixedly installed on the outer side of the fixed plate 1 610, and a sliding groove compatible with the second rotating shaft 644 is opened inside the fixed plate 1 610, and the spring 2 653 is in a stretched state.

[0068] In this embodiment, the elastic force of the telescopic rod 2 652 is used to pull the pulling frame 651, which drives the driven wheel 2 645 to pull the conveyor belt 6491 through the rotating shaft 2 644, so that the conveyor belt 6491 is in a tensioned state, thereby maintaining good contact between the conveyor belt 6491 and the driving wheel 1 641, the driven wheel 1 643, the driven wheel 2 645, the driven wheel 3 647, the driven wheel 4 649 and the driving wheel 2 6490, thereby improving the transmission efficiency and reducing the slippage of the conveyor belt 6491, which helps to ensure the stability of the transmitted power and torque and avoid energy loss and system instability.

[0069] Working principle: the user connects the device to an external power source and then turns on the switch. The user holds the handle 4, moves the welding gun 1 to the place where welding is required, and starts the motor 1 551, so that when the rotating output shaft of the motor 1 551 drives the rotating shaft 2 552 and the circular gear 1 553 to rotate, the circular gear 1 553 is meshed with the teeth of the circular gear 2 554, and then the circular gear 2 554 drives the synchronous frame 541 to rotate. The limit block 542 is stuck in the inside of the synchronous frame 541 and is fixedly installed on the outside of the rotating shaft 1 521, so that when the synchronous frame 541 rotates, the synchronous frame 541 drives the two sets of rotating shafts 552 through the limit block 542. The driving shaft 1 521 rotates, and the teeth of the half gear 522 and the frame 523 are meshed, and the slide bar 525 is inserted into the inside of the top plate 3, so that the frame 523 drives the slide bar 525 to move in a reciprocating trajectory inside the top plate 3 through the top frame 524, and then the frame 523 drives the welding gun 1 to move in a reciprocating trajectory through the bottom frame 526 and the base 2, and the rotating shaft 1 521 drives the driving wheel 1 641 to rotate through the limit bar 630, thereby providing a power source for the driving wheel 1 641, so that when the driving wheel 1 641 drives the conveyor belt 6491 to rotate, the conveyor belt 6491 and the driven wheel 1 643, the driven wheel 2 645, and the driven wheel 3 647 , the driven wheel 4 649 and the outer side of the driving wheel 2 6490 collide with each other, so that the driving wheel 2 6490 drives the rotating shaft 4 670 to rotate. At this moment, the bevel gear 2 663 and the bevel gear 1 662 are meshed through the teeth, so that the bevel gear 1 662 drives the power-assisting wheel 664 to rotate through the rotating shaft 5 661, so that the power-assisting wheel 664 drives the welding gun 1 to move. The elastic force of the telescopic rod 2 652 pulls the pulling frame 651 to drive the driven wheel 2 645 to pull the conveyor belt 6491 through the rotating shaft 2 644, so that the conveyor belt 6491 is in a tensioned state, thereby keeping the conveyor belt 6491 and the driving wheel 1 641 and the driven wheel 1 64 3. The driven wheel 2 645, the driven wheel 3 647, the driven wheel 4 649 and the driving wheel 2 6490 are in good contact, and the telescopic rod 2 652 is started. The rotating output shaft of the motor 2 562 drives the rotating shaft 3 563 and the circular gear 3 564 to rotate. At this moment, the circular gear 3 564 is meshed with the two sets of racks 565 through teeth, and the sliding rod 566 is inserted into the inside of the shell 561 to limit the rack 565, so that the rack 565 can stably drive the connecting rod 567 to cooperate with the limiting ring 2 568 to be stuck in the inside of the connecting rod 567, so that the rotating shaft 1 521 drives the appropriate half gear 522 to mesh with the appropriate frame 523.
