Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically to a welding device for automotive parts. Background Technology

[0002] Welding is a process that achieves atomic bonding between two separate metal surfaces to form a permanent connection. Under the influence of temperature and gravity, the molten liquids of the two workpieces mix. As the temperature decreases, the molten portion solidifies, and the two workpieces are tightly welded together. In the automotive industry, welding is a crucial step in the manufacturing of automotive parts and bodies. An existing automotive parts welding device (Announcement No.: CN221560327U) has the following drawbacks in use:

[0003] After welding is completed, the welded shaft needs to be removed from the first and second rotating drums before the next shaft can be placed on the first and second rotating drums for the next welding. This makes it inconvenient to quickly load and unload materials, resulting in low efficiency in the welding process of automotive parts. Therefore, this patent proposes an automotive parts welding device to solve the above problems. Utility Model Content

[0019] Welding is a process that combines two separate metal surfaces to form a permanent bond by achieving atomic bonding. Under the influence of temperature field, gravity, and other factors, the molten liquids of the two workpieces mix. As the temperature decreases, the molten part solidifies, and the two workpieces are tightly welded together. In the automotive industry, welding is a crucial step in the manufacturing of automotive parts and bodies.

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: a welding device for automotive parts, wherein a support frame 2 is fixed at the top of a workbench 1, a welding mechanism is provided on the inner wall of the top of the support frame 2, a movable frame 3 is slidably connected between the inner walls of the two sides of the workbench 1, two sets of clamping parts are provided on the movable frame 3, a first sliding groove is provided on one side of the workbench 1, a second lead screw is rotatably connected between the inner walls of the two ends of the first sliding groove, a third slider 16 is screwed to the outer wall of the second lead screw, the third slider 16 is fixed to one side of the movable frame 3, a second motor 17 is fixed at one end of the workbench 1, the output end of the second motor 17 passes through the workbench 1 and is fixed to the second lead screw, a second sliding groove is provided on the other side of the workbench 1, a movable block 14 is slidably connected in the second sliding groove, and the movable block 14 is fixed to the other side of the movable frame 3.

[0021] It should be noted that by starting the second motor 17, the second motor 17 drives the second lead screw to rotate, the rotation of the second lead screw drives the third slider 16 to move, the movement of the third slider 16 drives the moving frame 3 to move, and the movement of the moving frame 3 drives a set of clamping parts to move below the welding mechanism. The welding mechanism then welds the welding parts on the clamping parts. During the welding process, the operator can remove the previously welded welding part from another set of clamping parts and install another welding part on another set of clamping parts, thus realizing loading and unloading.

[0022] like Figure 3 As shown, the bottom end of the movable frame 3 is provided with a first groove 7 and a second groove 8. A first lead screw 9 is rotatably connected between the inner walls of both sides of the first groove 7 and the second groove 8. Two first motors 13 are fixed on the other side of the movable frame 3. The output end of the first motor 13 passes through the movable frame 3 and is fixed to the first lead screw 9. The first lead screw 9 is a bidirectional lead screw. A first slider 10 and a second slider 11 are screwed to the outer wall of the first lead screw 9. A first moving plate 5 and a second moving plate 6 are fixed to one end of the first slider 10 and the second slider 11, respectively. The clamping member is set on the side where the first moving plate 5 and the second moving plate 6 are close to each other.

[0023] It should be noted that by starting the first motor 13, the first motor 13 drives the first lead screw 9 to rotate, and the rotation of the first lead screw 9 drives the first slider 10 and the second slider 11 to move, which facilitates the clamping of welding parts of different lengths. The clamping device can be a pneumatic chuck to clamp automotive parts inside the round shaft. A third motor is installed on the side of the first moving plate 5 and the second moving plate 6 that are far apart from each other, and the clamping device is driven to rotate by the third motor.

[0025] It should be noted that the first protective cover 12 and the second protective cover 15 respectively protect the first lead screw 9 and the second lead screw, preventing welding spatter from falling onto the surfaces of the first lead screw 9 and the second lead screw and affecting their use. By starting the fan 21, the fan 21 sucks away the exhaust gas generated during the welding process, and then discharges it into the existing exhaust gas treatment device through the exhaust pipe 22 for exhaust gas treatment. When welding is required, the cylinder is started, and the cylinder drives the welding head to move downward, and the welding head moves downward to weld the workpiece. In this solution, the control method of the electrical components is controlled by the matching controller 18, and the control circuit can be implemented by those skilled in the art through simple programming. It is common knowledge in the art and is only used without modification. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.
