Description

Technical Field

[0001] The utility model relates to the technical field of percussion welding, in particular to a percussion welding device for sheet metal parts. Background Art

[0002] Percussion welding refers to a welding method that uses the resistance heat generated by an electric current passing through the metal contact point to melt and combine the metal. During the percussion welding process of sheet metal parts, two or more sheet metal parts to be welded are placed between the electrodes. The electrodes accurately position the workpiece through a preset program. When the electrodes apply pressure to compress the sheet metal parts together, the electric current passes through the metal parts to generate resistance heat, causing the metal at the contact point to rapidly heat up and melt. In the molten state, the metal forms a firm welding point under pressure. After cooling, the metal materials combine into a complete whole at the contact point.

[0003] In the field of welding, platinum has become a challenging material due to its unique physical and chemical properties. Firstly, the melting point of platinum is quite high, which requires us to provide sufficient heat during welding to ensure that platinum can be fully melted and form a reliable weld. However, the high density of platinum makes it more difficult to control during the welding process. In addition, platinum also has excellent chemical stability, which makes its reaction with other metals or materials during welding more complex. Therefore, we not only need to consider how to provide enough energy to melt platinum, but also think about how to ensure the quality of the weld and avoid any problems during the welding process. At the same time, when we face circular platinum workpieces, the welding difficulty further increases. Since circular workpieces do not have fixed edges or corners as positioning references, it is easy to have problems with position deviation during the welding process. In addition, there are also certain difficulties in fixing circular workpieces. Once affected by external forces or heat, they are prone to deformation or movement, which undoubtedly increases the complexity of welding. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a percussion welding device for sheet metal parts to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is:

[0006] The sheet metal welding device includes a bracket and a rotating component. Two movable grooves are arranged on the upper end of the bracket. A first motor is fixedly installed on one side of the top end of the bracket. A first threaded rod is rotatably installed in the two movable grooves. Two gears are fixedly installed on one end of the two first threaded rods. The two gears are connected by a transmission belt. One end of one of the first threaded rods is fixedly connected to the output end of the first motor. A welding component is threadedly connected to the first threaded rod. The rotating component is fixedly installed on the upper end of the bracket. The rotating component includes a second motor fixedly installed on the upper end of the bracket. A worm is fixedly installed on the output end of the second motor. The worm is rotatably installed on the upper end of the bracket. A shell is fixedly installed on the upper end of the bracket. A rotating drum is rotatably installed inside the shell. A worm wheel is fixedly installed on the outside of the rotating drum. The worm wheel is meshingly connected with the worm. A clamping member is provided inside the rotating drum.

[0007] The above technical scheme is adopted. In this scheme, the staff clamps the round tube by the clamping member when in use, and then welds the round tube by the welding assembly. After welding is completed, the second motor is started to drive the transmission rod to rotate the worm gear, so that the round tube is turned over and welded to other positions of the round tube. The setting of the rotating assembly allows the round tube to rotate during welding. The staff can easily adjust the position of the round tube so that the welding assembly can reach the part that needs to be welded at the same position of the round tube. The setting of the second motor improves the automation degree and efficiency of the welding operation during welding. Through the control of the second motor, the rotating assembly can rotate smoothly, thereby avoiding many inconveniences and inefficiencies caused by workers manually rotating the rotating assembly. Through the setting of the worm, the round tube can be prevented from accidentally rotating due to improper operation or external force interference during welding.

[0008] A further improvement of the technical solution of the utility model is that the clamping member includes a tapered column, which is threadedly connected to the inside of the rotating drum, a circular ring is fixedly installed inside the rotating drum, a plurality of outer clamping plates are equidistantly rotatably installed on the outer ring of the circular ring, and a plurality of inner clamping plates are equidistantly rotatably connected to the inner ring of the circular ring.

[0009] The above technical solution is adopted. In this solution, the conical column is rotated when clamping the round tube. Due to the setting of the conical column, the side wall of the conical column pushes several inner clamps to be squeezed outward, and at the same time, pushes one end of several outer clamps to use the connection on the circular ring as a lever to squeeze the other end of the outer clamp inward.

[0010] A further improvement of the technical solution of the utility model is that the welding assembly includes a moving column, two moving columns are respectively threadedly installed on two first threaded rods, two adjusting disks are fixedly installed at one end of the two moving columns away from the first threaded rods, and welding contacts are slidably installed in the adjusting disks.

[0011] With the above technical solution, in this solution, through the setting of the adjustment disc, the welding assembly can adapt to round tubes with different bending degrees, which means that regardless of the bending degree of the round tube, the staff can adjust the adjustment disc to ensure that the welding contact head can accurately reach the welding position.

[0012] A further improvement of the technical solution of the present utility model lies in that: scale discs are provided on the two adjustment discs.

[0013] With the above technical solution, in the case where there is no scale disc in this solution, the staff may only rely on experience and feeling to adjust the position of the welding contact head, which is likely to cause errors. The setting of the scale disc greatly reduces such errors, making the welding process more controllable and reliable.

[0014] A further improvement of the technical solution of the present utility model lies in that: a second threaded rod is rotatably installed at the upper end of the bracket, a slide rail is fixedly installed at the upper end of the bracket, a fixing member is slidably installed on the slide rail, the second threaded rod is threadedly connected to the bottom end of the fixing member, and a third motor is fixedly installed on the side end of the bracket, and the output end of the third motor is fixedly connected to one end of the second threaded rod.

[0015] With the above technical solution, in this solution, through the setting of the threaded connection between the second threaded rod and the fixing member, combined with the precise control of the third motor, the precise adjustment of the distance between the fixing member and the rotating assembly during the welding of round tubes with different lengths can be achieved. This design not only improves the welding quality and efficiency but also enhances the safety and operability of the equipment.

[0016] A further improvement of the technical solution of the present utility model lies in that: the fixing member includes a housing, the housing is slidably installed at the upper end of the slide rail, a limiting plate is rotatably installed at the upper end of the housing, a number of limiting grooves are provided at both ends inside the housing and the limiting plate, a number of sliders are slidably connected in the number of limiting grooves, a runner is rotatably installed between every two sliders, springs are provided in the number of limiting grooves, one end of the spring is fixedly connected to the limiting plate, and the other end of the spring is fixedly connected to the slider.

[0017] With the above technical solution, in this solution, through the setting of the limiting plate, the presence of the limiting plate can limit the movement of the round tube within the fixing member, ensuring its stability during the welding process. The design of the runner can increase the contact area between the round tube and the fixing member while reducing friction, enabling the round tube to move and adjust its position more smoothly within the fixing member. The presence of the spring can provide a certain elastic support for the slider and the runner, enabling the fixing member to better adapt to round tubes with different diameters.

[0018] A further improvement of the technical solution of the present utility model lies in that: anti-slip pads are fixedly installed on the inner sides of a number of outer clamping plates.

[0019] With the above technical solution, in this solution, by fixedly installing an anti-slip pad on the inner side of the outer clamp, when the clamping member clamps the round tube, the presence of the anti-slip pad can effectively prevent the round tube from sliding or falling off during the clamping process.

[0020] Due to the adoption of the above technical solution, the technical progress achieved by the present utility model compared with the prior art is as follows:

[0021] 1. The present utility model provides a sheet metal part spot welding device. Through the setting of the rotating assembly, the round tube can rotate during welding, and the staff can conveniently adjust the position of the round tube, so that the welding assembly can reach the parts that need to be welded in one circle at the same position of the round tube. Through the setting of the second motor, the automation degree and efficiency of the welding operation are improved during welding. Through the control of the second motor, the rotating assembly can rotate smoothly, thus avoiding the many inconveniences and low efficiency problems brought by manual rotation of the rotating assembly by workers. Through the setting of the worm, the round tube can be prevented from accidentally rotating due to improper operation or external interference during welding. In addition, through the setting of the conical column, when clamping the round tube, rotate the conical column. Due to the setting of the conical column, the side wall of the conical column pushes several inner clamps to extrude outward, and at the same time pushes one end of several outer clamps to make the other end of the outer clamp extrude inward with the connection on the ring as the lever, so that the inner clamp and the outer clamp can clamp the cylinder more stably.

[0022] 2. The present utility model provides a sheet metal part spot welding device. Through the setting of the adjusting disc, the welding assembly can adapt to round tubes with different bending degrees. This means that no matter what the bending degree of the round tube is, the staff can ensure that the welding contact head can accurately reach the welding part by adjusting the adjusting disc. In addition, without a scale disc, the staff may only rely on experience and feeling to adjust the position of the welding contact head, which is likely to cause errors. The setting of the scale disc greatly reduces such errors, making the welding process more controllable and reliable.

[0023] 3. The present utility model provides a sheet metal part spot welding device. Through the setting of the threaded connection between the second threaded rod and the fixed member, combined with the precise control of the third motor, the distance between the fixed member and the rotating assembly during welding of round tubes with different lengths can be accurately adjusted. This design not only improves the welding quality and efficiency, but also enhances the safety and operability of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0034] The following further elaborates on the present utility model in conjunction with embodiments:

[0035] Embodiment 1

[0036] As Figures 1 - 8 shown, the present utility model provides a sheet metal part butt welding device, including a support 1 and a rotating assembly. Two moving grooves are provided at the upper end of the support 1. A first motor 2 is fixedly installed on one side of the top end of the support 1. Two first threaded rods 3 are rotatably installed in the two moving grooves. Two gears 4 are fixedly installed at one ends of the two first threaded rods 3. The two gears 4 are connected by a transmission belt. One end of one of the first threaded rods 3 is fixedly connected to the output end of the first motor 2. A welding assembly is threadedly connected to the first threaded rod 3; the rotating assembly is fixedly installed at the upper end of the support 1. The rotating assembly includes a second motor 5 fixedly installed at the upper end of the support 1. The output end of the second motor 5 is fixedly installed with a worm 6. The worm 6 is rotatably installed at the upper end of the support 1. A housing 7 is fixedly installed at the upper end of the support 1. A rotating cylinder 8 is rotatably installed inside the housing 7. A worm wheel 26 is fixedly installed on the outside of the rotating cylinder 8. The worm wheel 26 is meshed with the worm 6. A clamping member is provided inside the rotating cylinder 8.

[0037] In this embodiment, when in use, the staff clamps the circular tube through the clamping member, and then welds the circular tube through the welding assembly. After welding is completed, the second motor 5 is started to drive the transmission rod to rotate the worm gear 26, so as to turn the circular tube over to weld other positions of the circular tube. Through the setting of the rotating assembly, the circular tube can rotate during welding, and the staff can conveniently adjust the position of the circular tube, so that the welding assembly can reach the parts that need to be welded in one circle at the same position of the circular tube. Through the setting of the second motor 5, the automation degree and efficiency of the welding operation are improved during welding. Through the control of the second motor 5, the rotating assembly can rotate smoothly, thus avoiding many inconveniences and inefficiencies brought by the worker manually rotating the rotating assembly. Through the setting of the worm 6, the circular tube is prevented from accidentally rotating due to improper operation or external interference during welding.

[0038] As Figure 7 shown, in this embodiment, preferably, the clamping member includes a tapered column 9, the tapered column 9 is threadedly connected inside the rotating cylinder 8, a circular ring 10 is fixedly installed inside the rotating cylinder 8, and a plurality of outer clamping plates 11 are rotatably installed at equal intervals on the outer ring of the circular ring 10, and a plurality of inner clamping plates 12 are rotatably connected at equal intervals on the inner ring of the circular ring 10.

[0039] In this embodiment, when clamping the circular tube, the tapered column 9 is rotated. Due to the setting of the tapered column 9, the side wall of the tapered column 9 pushes a plurality of inner clamping plates 12 to extrude outward, and at the same time pushes one end of a plurality of outer clamping plates 11 to use the connection point on the circular ring 10 as a lever to make the other end of the outer clamping plate 11 extrude inward.

[0040] As Figure 4 and Figure 5 shown, preferably, the welding assembly includes a moving column 13. The two moving columns 13 are respectively threadedly installed on the two first threaded rods 3. The ends of the two moving columns 13 away from the first threaded rods 3 are fixedly installed with two adjusting discs 14, and a welding contact head 15 is slidably installed inside the adjusting disc 14.

[0041] In this embodiment, through the setting of the adjusting disc 14, the welding assembly can adapt to circular tubes with different bending degrees, which means that no matter what the bending degree of the circular tube is, the staff can ensure that the welding contact head 15 can accurately reach the welding part by adjusting the adjusting disc 14.

[0042] Embodiment 2

[0043] As Figure 2 and Figure 4 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: preferably, scale discs 16 are provided on the two adjusting discs 14.

[0044] In this embodiment, in the absence of the dial 16, the staff may only rely on experience and feeling to adjust the position of the welding contact 15, which is likely to cause errors. The setting of the dial 16 greatly reduces such errors, making the welding process more controllable and reliable.

[0045] As Figure 1 and Figure 3 shown, preferably, a second threaded rod 17 is rotatably installed at the upper end of the bracket 1, a slide rail is fixedly installed at the upper end of the bracket 1, a fixing member is slidably installed on the slide rail, the second threaded rod 17 is threadedly connected to the bottom end of the fixing member, and a third motor 19 is fixedly installed on the side end of the bracket 1. The output end of the third motor 19 is fixedly connected to one end of the second threaded rod 17.

[0046] In this embodiment, through the setting of the threaded connection between the second threaded rod 17 and the fixing member, combined with the precise control of the third motor 19, the precise adjustment of the distance between the fixing member and the rotating assembly during the welding of round tubes of different lengths can be achieved. This design not only improves the welding quality and efficiency but also enhances the safety and ease of operation of the equipment.

[0047] Embodiment 3

[0048] As Figure 3 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: preferably, the fixing member includes a housing 18. The housing 18 is slidably installed at the upper end of the slide rail. A limiting plate 20 is rotatably installed at the upper end of the housing 18. A number of limiting grooves 21 are provided at both ends inside the housing 18 and the limiting plate 20. A number of sliders 22 are slidably connected in the number of limiting grooves 21. A runner 23 is rotatably installed between every two sliders 22. Springs 24 are provided in the number of limiting grooves 21. One end of each spring 24 is fixedly connected to the limiting plate 20, and the other end of each spring 24 is fixedly connected to the slider 22.

[0049] In this embodiment, through the setting of the limiting plate 20, the presence of the limiting plate 20 can limit the movement of the round tube within the fixing member, ensuring its stability during the welding process. The design of the runner 23 can increase the contact area between the round tube and the fixing member while reducing friction, enabling the round tube to move and adjust its position more smoothly within the fixing member. The presence of the springs 24 can provide a certain elastic support for the sliders 22 and the runner 23, enabling the fixing member to better adapt to round tubes of different diameters.

[0050] Embodiment 4

[0051] As Figure 7 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: preferably, anti-slip pads 25 are fixedly installed on the inner sides of a number of outer clamping plates 11.

[0052] In this embodiment, by fixedly installing an anti-slip pad 25 on the inner side of the outer clamping plate 11, the presence of the anti-slip pad 25 can effectively prevent the circular tube from sliding or falling off during the clamping process when the clamping member clamps the circular tube.

[0053] Next, the working principle of the sheet metal part butt welding device will be specifically described.

[0054] As Figures 1 - 8 shown, when in use, the staff places the circular tube between the inner clamping plate 12 and the outer clamping plate 11. The onboarding staff uses the handle on the tapered column 9 to rotate the tapered column 9. Due to the setting of the tapered column 9, the side wall of the tapered column 9 pushes several inner clamping plates 12 outwards to squeeze the circular tube outwards, and at the same time pushes one end of several outer clamping plates 11 so that the other end of the outer clamping plate 11 squeezes the circular tube inwards with the connection point on the ring 10 as a lever. The other end of the circular tube is placed in the fixing component and fixed by the limiting plate 20. The circular tube contacts the rotating wheel 23. At this time, the outer clamping plate 11 and the inner clamping plate 12 firmly clamp the circular tube. According to the size of the circular tube, the third motor 19 and the first motor 2 are used to adjust the fixing component and the welding component to a suitable position, and then the circular tube is welded by the welding contact head 15. The angle of the adjusting disc 14 is adjusted according to the shape of the circular tube. After the adjustment is completed, the welding contact head 15 is fastened by the fastener at the upper end of the adjusting disc 14. After the welding is completed, the second motor 5 is started to drive the worm wheel 26 to rotate, so as to flip the circular tube to weld other positions of the circular tube. The setting of the rotating component enables the circular tube to rotate during welding, and the staff can conveniently adjust the position of the circular tube so that the welding component can reach the part that needs to be welded in a circle at the same position of the circular tube.

[0055] The above generally describes the present invention in detail, but based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
