Description

Technical Field

[0001] The utility model relates to a welding device for a flange joint of an automobile air-conditioning pipe, belonging to the technical field of welding devices. Background Art

[0002] In the mass production process of automotive air conditioning pipes, welding flange joints is a critical step. The quality of welding is directly related to the final quality of the product. This process is usually completed on a specific welding equipment. In daily operation, a welding equipment often needs to switch to process multiple different product models within a day.

[0003] Every time the model is changed, the shape and size of the joint will change, and the workers have to readjust the position and angle of the welding gun. Since there is no reference during adjustment, they can only aim at the approximate welding position with the naked eye each time. Although experienced workers can adjust with their own skills, it is actually difficult to achieve perfect alignment every time. If the welding position is slightly deviated, the strength of the joint may not be enough, and the sealing may also deteriorate, which will not only affect the effect of the air conditioner, but also may bring safety hazards. Moreover, frequent model changes and adjustments will also reduce production efficiency. Workers may need to spend more time adjusting and correcting, which will slow down the entire production line.

[0004] Therefore, in order to solve the problem of inaccurate heating position of the gun tip during the changeover process and improve the quality and efficiency of welding of automotive air-conditioning pipe flange joints, we need a new type of welding equipment. Utility Model Content

[0005] The purpose of the utility model is to provide a new technical solution to improve or solve the technical problems existing in the prior art as described above.

[0007] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects: in order to solve the problem of uncertainty in the heating position of the gun head when changing models, the utility model arranges an infrared laser on the welding gun, and the infrared laser emitted by the infrared transmitter is consistent with the path of the arc sprayed by the welding gun. Through this overlap, the welding position can be accurately determined, thereby ensuring the accuracy and quality of the welding position. The welding equipment of the utility model can adapt to different product models more quickly, reduce the time for manual adjustment of the welding gun, and make welding more accurate and stable, which can not only improve product quality, but also improve production efficiency, and provide better protection for the safety and comfort of the car.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, the mounting seat includes a bottom support seat, an intermediate support seat and an upper support seat arranged from bottom to top, the bottom support seat is slidably installed on the workbench, the intermediate support seat is slidably installed on the bottom support seat, the upper support seat is fixed above the intermediate support seat, and the upper support seat has two vertical support arms, both of which are provided with lead screws along the vertical direction, a nut pair is installed on the lead screw, and the welding gun mounting bracket is installed on the nut pair, and the welding gun mounting bracket can move up and down along the lead screw with the nut pair.

[0010] The beneficial effect of adopting the above further solution is that the mounting seat provides a flexible and precise position adjustment mechanism for the welding gun, so that it can adapt to welding requirements of different heights and angles.

[0011] Furthermore, it also includes a driving device, which is installed at the end of the lead screw to drive the lead screw to rotate.

[0012] Furthermore, the driving device is a driving handle, and the driving handle is rotatably mounted on the end of the lead screw, and the lead screw is driven to rotate by the driving handle.

[0013] The beneficial effect of adopting the above further scheme is that the up and down movement of the welding gun mounting bracket can be conveniently controlled by the driving handle, and due to the direct connection between the driving handle and the lead screw, the moving distance and speed of the welding gun mounting bracket can be more accurately controlled, thereby achieving more precise welding operations.

[0014] Furthermore, the driving device is a driving motor, and a driving shaft of the driving motor is drivingly connected to the lead screw.

[0015] Furthermore, the workbench is also provided with a clamping tool, and the clamping tool is used to clamp the workpiece to be welded.

[0016] Furthermore, a water tank is provided on the workbench, and the clamping tool is arranged in the water tank.

If it is not cooled in time, the workpiece may be deformed or have other quality problems due to the high temperature. Therefore, the clamping tool is set in the water tank. After the workpiece is welded, it can be directly immersed in the cooling water in the water tank to achieve rapid cooling. This can not only effectively prevent the deformation or quality problems of the workpiece caused by high temperature, but also ensure the dimensional accuracy and surface quality of the workpiece.

[0018] Furthermore, the clamping tooling includes a flange joint positioning seat, a support block and a bracket, the flange joint positioning seat is installed in the water tank, a latch is installed on the bracket, and the flange joint positioning seat, pipe support block, bracket and latch are arranged according to the bending direction of the workpiece to be welded.

Moreover, since the clamping fixture can closely match the shape of the workpiece, workers do not need to spend extra time and energy to adjust the position of the workpiece or redesign the clamping fixture during welding, thereby greatly improving work efficiency.

[0021] The beneficial effect of adopting the above further solution is that the ignition device can very conveniently control the ignition operation during the welding process.

[0022] Furthermore, the bottom support seat is installed on the workbench in a manner that it can slide along the X-axis direction, and the intermediate support seat is installed above the bottom support seat in a manner that it can slide along the Y-axis direction.

The welding gun mounting frame 204 can move up and down along the lead screw 205 with the nut pair 206. Each welding gun mounting frame 204 is provided with a row of welding gun mounting positions, and welding guns 10 are installed on the welding gun mounting positions. Through the above arrangement, two rows of welding guns 10 are formed on the workbench 1. The clamping fixture 4 is arranged between the two rows of welding guns 10. The ignition device 6 is installed above the welding module 2 for igniting the welding gun 10. It also includes an infrared transmitter 3, which is detachably mounted on the welding gun 10. The infrared laser emitted by the infrared transmitter 3 is consistent with the path of the arc sprayed by the welding gun 10. Through this overlap, the welding position can be accurately determined, thereby ensuring the accuracy and quality of welding.

[0034] In addition, in this embodiment,

[0035] The welding module 2 further comprises a driving device, which is installed at the end of the lead screw 205 and is used to drive the lead screw 205 to rotate.

[0036] The embodiment of the utility model does not limit the structure of the driving device, and the driving device can be a driving handle 207, which is rotatably mounted at the end of the lead screw 205, and the lead screw 205 is driven to rotate by the driving handle 207.

When the infrared transmitter 3 is turned on, the position where the emitted infrared laser is projected on the standard sample is the heating position of the gun head; then, the head adjustment screw on the welding gun mounting bracket 204 is loosened to fine-tune the gun head position. During the adjustment process, pay close attention to the feedback of the infrared laser to ensure that the position of the gun tip can be accurately aligned with the punching position of the standard sample, so as to achieve precise control of the heating position of the gun tip; finally, remove the standard sample, place the flange joint 8 to be welded on the flange joint positioning seat 401, install the air-conditioning pipe 9 along its direction on the support block 402, and use the pin 404 to fix it on the bracket 403, start welding, and weld the flange joint 8 to be welded to the air-conditioning pipe 9.
