Description

Technical Field

[0001] The invention belongs to the technical field of laser welding, and in particular relates to a welding device used for processing automobile parts. Background Art

[0002] The automotive parts industry provides corresponding parts products for the automobile manufacturing industry. Auto parts generally refer to all parts and components except the automobile frame. At present, automotive parts contain a variety of shaft parts, some of which need to be butt-welded to each other. Since the welding surface of the shaft parts is a curved surface, during the welding process, the shaft parts need to be clamped and axially rotated to achieve the curved surface welding.

[0003] The comparative document (application number: 202410076775.0, an automatic welding device for processing automobile parts) discloses: an automatic welding device for processing automobile parts, comprising a workbench, a lifting mechanism, a clamping mechanism and a welding mechanism; the interior of the workbench is a cavity, and a plurality of through slots are opened on the workbench, and the two ends of the plurality of through slots are respectively connected to the cavity inside the workbench and the outside of the workbench; the lifting mechanism is provided in plurality and is respectively arranged on the workbench, and the plurality of lifting mechanisms respectively lift the two shaft parts to be welded, and the shaft parts can be clamped by a plurality of lifting rollers, thereby lifting the shaft parts to be welded, so that the clamping mechanism drives the shaft parts to rotate, and the simultaneous movement of the plurality of lifting rollers toward the center can ensure that the two shaft parts to be welded always remain coaxial, and the axis alignment of the two shaft parts can be automatically completed without unnecessary operations, which helps to improve welding efficiency.

[0004] In the prior art, two shaft parts are rotated by themselves to achieve the purpose of all-round welding at the joint, but single-point continuous welding plus the joint being in a rotating state can easily cause local overheating and uneven stress distribution. Moreover, after the two shaft parts move toward each other in the horizontal direction and contact, friction is used to make them rotate synchronously and then perform curved surface welding. However, when welding the two shaft parts, it is necessary to selectively control the gap within the process standard range according to the welding process (a gap that is too small can easily lead to incomplete penetration of the weld root and reduce the joint strength due to insufficient penetration; a gap that is too large can easily burn through and produce defects such as weld nodules and pores). In addition, when the friction generated by mutual extrusion is used to make the two shaft parts rotate synchronously, during the welding process, the contact surfaces of the two shaft parts gradually soften, the friction is reduced or even lost, and it is difficult to maintain the synchronous rotation of the two shaft parts, which is not conducive to comprehensive welding.

[0033] Example 1

[0034] Reference Figure 1 、 Figure 3-Figure 7 A welding device for processing automobile parts comprises a welding head support module 1 and a shaft part support module 2, wherein the welding head support module 1 is located above the shaft part support module 2;

[0035] The welding head support module 1 includes: a gantry 11, a motor A12 is installed in the middle of the outer wall of one side of the gantry 11, the output end of the motor A12 is fixedly connected to the rotating disk 13, and the outer circumference of the rotating disk 13 is reserved with a tooth gap 1. A rotating ring 14 is movably installed on the gantry 11, and the outer circumference of the rotating ring 14 is reserved with a tooth gap 2, and the tooth gaps 1 and 2 are engaged with each other. A rotating sleeve 15 is installed at one end of the rotating ring 14, and a symmetrical welding module 16 is installed on the rotating sleeve 15.

[0036] The symmetrical welding module 16 includes: a pair of motor seats 161 symmetrically mounted on the outer circumference of the rotating sleeve 15 near the upper end, a motor B162 mounted on the outer surface of one of the motor seats 161, the output end of the motor B162 being fixedly connected to a worm 163, the worm 163 being composed of two worms fixedly connected in opposite directions of rotation, a pair of supports 164 symmetrically mounted on the outer circumference of the rotating sleeve 15 near the pair of motor seats 161, a rotating disk 2 165 being rotated on the outer surface of each of the pair of supports 164, a tooth gap 3 being reserved on the outer circumference of the rotating disk 2 165, and a turbine 166 being mounted in the center of one side wall of the rotating disk 2 165, the turbine 166 being transmission-connected to the worm 163;

[0037] A pair of axially adjustable rings 167 are movably mounted on the inner surface of the rotating sleeve 15. The outer peripheral surface of the axially adjustable ring 167 is reserved with tooth gap four, which is engaged with tooth gap three. A welding head seat 168 is mounted on the inner surface of the pair of axially adjustable rings 167. A welding head 169 is mounted on one side end of the welding head seat 168. The two welding heads 169 are at the same horizontal height.

[0038] In this embodiment, when welding the joints of two shaft parts, the joints of the two shaft parts and the rotating sleeve 15 are placed on the same horizontal axis, and the two welding heads 169 are located on the outside of the joints. When performing the welding operation, the motor B162 in the symmetrical welding module 16 is first regulated to work, and the motor B162 pulls the two worms 163 to rotate. Through the transmission between the worm 163 and the turbine 166, the worm 163 pulls the turbine 166 to rotate. At this time, the turbine 166 pulls the rotating disk 2 165 to rotate. Through the bite connection between the rotating disk 2 165 and the axial variable ring 167, the rotating disk 2 165 pulls the axial variable ring 167 to rotate. The welding head seat 168 and the welding head 169 on the axial variable ring 167 move axially synchronously. The two welding heads 169 rotate in directions toward or away from each other. The welding heads 169 are symmetrically welded to the joints of the two shaft parts, and symmetrical welding is used to achieve 180-degree welding of the outer circumference of the joint.

[0039] Then, the output end of the motor A12 is regulated to rotate the rotating disk 13. Through the interlocking connection between the rotating disk 13 and the rotating ring 14, the rotating disk 13 rotates the rotating ring 14, and the rotating sleeve 15 on the rotating ring 14 rotates synchronously. At this time, the symmetrical welding module 16 on the rotating sleeve 15 rotates synchronously, and the welding head 169 performs axial movement. The angle of the welding head 169 in the symmetrical welding module 16 can be adjusted so that the welding head 169 can continue to symmetrically weld the unwelded parts at the joint of the two shaft parts, thereby achieving full-range welding of the joint.

[0040] By making the double welding joints 169 move axially in opposite directions so that their movement trajectories are in a symmetrical state, and by rotating the rotating sleeve 15, the circumferential orientation of the double welding joints 169 can be adjusted so as to perform symmetrical welding again, thereby realizing 360-degree all-round welding at the joints of the two shaft parts. By performing symmetrical welding operations on the joints of the two shaft parts, the welding heat and stress can be evenly distributed, ensuring uniform distribution of the welds, reducing local overheating, and ensuring consistent weld parameters and reducing the defect rate.

[0048] The welding measurement module 25 is installed on the movable shaft part fastening module 23 and is connected to the traction module 24. When the shaft part fastening module 23 is pulled to move left and right in the support platform 21, the traction module 24 simultaneously pulls the welding measurement module 25 to measure the shaft parts fastened on the movable shaft part fastening module 23. The welding measurement module 25 includes an arched guide port 251 reserved on the outer surface of the variable platform 231 and an arched guide platform 252 movable in the arched guide port 251. A measuring sleeve 253 is fixed on the outer surface of the arched guide platform 252. A distance sensor 254 is installed on the outer surface of the measuring sleeve 253.

The circumference of the opening of the arched guide opening 251 is smaller than the circumference of the arched guide platform 252, preventing the arched guide platform 252 from falling off from the arched guide opening 251.

[0049] Use the fixed shaft part fastening module 23 to fasten one shaft part, and use the movable shaft part fastening module 23 to fasten another shaft part. When fastening the shaft parts, place the shaft part to be fastened in the support platform 21, then control the output end of the electric push rod 233 to extend, pull the fastening unit 234 downward to fasten the shaft part, then control the output end of the electric push rod 233 to reset, so that the distance the output end of the electric push rod 233 extends is the same as the distance the output end of the electric push rod 233 on the fastened shaft part fastening module 23 is extended. Therefore, when the shaft part fastening module 23 fastens the shaft part, the user does not need to pick up the shaft part and pass it through the fastening unit 234, making the fastening of the shaft part easy and convenient.

[0050] Then, when the shaft parts are fastened and connected, the movably mounted shaft part fastening module 23 is manipulated to move toward the fixed shaft part fastening module 23, so that the pair of shaft part fastening modules 23 are brought closer to each other, and the shaft parts fastened on the pair of shaft part fastening modules 23 are connected. The operation steps of manipulating the movably mounted shaft part fastening module 23 are as follows: starting the motor C2303, using the motor C2303 to pull the stud A2304 to rotate, the stud A2304 pulling the T-shaped guide platform 2301 to move, and the T-shaped guide platform 2301 pulling the movably mounted shaft part fastening module 23 to move, so that the shaft parts are connected;

[0051] When the T-shaped guide platform 2301 pulls the movably installed shaft parts fastening module 23 to change, the traction module 24 simultaneously pulls the welding point measurement module 25 to measure the outer peripheral surface of the shaft parts fastened on the movable shaft parts fastening module 23, so there is no need to install a power unit to pull the welding point measurement module 25 to rotate, which not only avoids the high cost and complicated technology of the device, but also ensures the measurement of the outer peripheral surface of the shaft parts during the connection period, realizes the measurement of the coaxiality of the shaft parts, avoids deflection after welding, and ensures the coincidence of the axes.

[0052] The traction module 24 simultaneously pulls the welding measurement module 25 to measure the shaft parts fastened on the movable shaft parts fastening module 23. The operation steps are as follows: when the T-shaped guide platform 2301 pulls the movably installed shaft parts fastening module 23 to change and complete the connection of the shaft parts, at this moment, the movably installed shaft parts fastening module 23 simultaneously pulls the rotating column 241 to change. When the rotating column 241 changes, the traction guide platform 245 fixed to the inner surface of the supporting platform 21 changes in the threaded opening 244 reserved on the outer surface of the rotating column 241, thereby pulling the rotating column 241 to rotate. The rotation of the rotating column 241 pulls the rotating disk three 242 to rotate. The rotation of the rotating disk three 242 pulls the ring 255 to rotate, driving the ring 255 to pull the measuring sleeve 253 to rotate, and then pulling the distance measuring sensor 254 installed on the measuring sleeve 253 to rotate one circle, thereby measuring the outer peripheral surface of the shaft parts, and the measured data is transmitted to the control end.
