Description

Technical Field

[0001] The present invention relates to the technical field of automobile chassis welding, and in particular to a high-stability welding device for an automobile chassis. Background Art

[0002] The chassis supports the vehicle's weight and effectively transmits road impact, driving control forces, and powertrain output to the ground. The chassis' design determines the vehicle's stability, handling, comfort, and safety.

[0003] The anti-collision beam (also called the body anti-collision beam or bumper beam) is a structural component installed inside the front and rear bumpers of a car. Its main function is to absorb and disperse the impact force in the event of a collision, reducing damage to the car body and passengers. The main function of the anti-collision beam is to absorb energy and disperse the impact force. If the anti-collision beam is not firmly connected to the chassis, it may not be able to effectively transmit the impact force in the event of a collision, causing the impact energy to act directly on other parts of the car body, increasing the risk of injury to the occupants of the car. The stable welding of the anti-collision beam can ensure that it will not fall off or shift in the event of a collision, ensuring that the front and rear parts of the vehicle are effectively protected in the event of an impact. If the anti-collision beam becomes loose or falls off, the structural strength of the entire vehicle will be significantly reduced, increasing the possibility of secondary damage.

When the welding firmness of the clamping block 105 and the clamping plate 204 is detected, the detection plate 302 is driven to slide on the mounting frame 301, and the detection plate 302 moves toward the automobile chassis 104, driving the two sets of oscillation frames 303 to detect The plate 302 slides, and the oscillation frame 303 drives the limit head 305 to move. The gap between the limit head 305 and the push plate 316 is aligned with the anti-collision bar 205, and the detection column 306 fits with the outer wall of the anti-collision bar 205. At this time, the displacement detector returns to zero and drives the push plate 316 to slide on the detection plate 302. After the push plate 316 fits with the inner wall of the anti-collision bar 205, it continues to drive the push plate 316. The two groups of push plates 316 push the anti-collision bar 205 in opposite directions at the same time. If the anti-collision bar 205 is not firmly welded to the car chassis 104, the anti-collision bar 205 will fall off or shift.

A grinding disc 309 is rotatably provided on the adjustment block 308. The grinding disc 309 grinds the surface of the automobile chassis 104 to improve the welding effect of other welded parts.

[0031] Working principle: When working, the automobile chassis 104 is placed on the clamping frame 103, and the two groups of clamping blocks 105 are driven to approach each other. The clamping blocks 105 drive the clamping plate 106 to reach above the automobile chassis 104, and drive the clamping plate 106 to move toward the direction of the clamping frame 103. The two groups of clamping plates 106 press the automobile chassis 104 on the clamping frame 103 to complete the fixation of the clamping frame 103. When the position of the automobile chassis 104 needs to be adjusted, the mounting frame 102 is driven to rotate on the base 101, and the mounting frame 102 drives the automobile chassis 104 to rotate along the axis of the base 101. When the clamping frame 103 is driven to rotate on the mounting frame 102, the clamping frame 103 drives the automobile chassis 104 to rotate, and the position of the automobile chassis 104 is adjusted.

[0032] Place the anti-collision bar 205 between the clamping plate 204 and the adjustment frame 203, drive the clamping plate 204 to approach the adjustment frame 203, the clamping plate 204 presses the anti-collision bar 205 on the adjustment frame 203, complete the fixation of the anti-collision bar 205, drive the grinding frame 208 to slide on the bracket 201, the grinding frame 208 drives the grinding roller 211 to approach the anti-collision bar 205, drive the mounting block 209 to slide on the grinding frame 208, and the mounting block 209 drives the grinding roller 211 to move and adjust the position of the grinding roller 211, and the grinding roller 211 fits with the anti-collision bar 205.

[0033] When welding the anti-collision bar 205, the second mounting frame 202 is driven to slide on the bracket 201, and the second mounting frame 202 drives the adjustment frame 203 and the anti-collision bar 205 to move, and the adjustment frame 203 is driven to rotate on the second mounting frame 202, and the adjustment frame 203 drives the anti-collision bar 205 to rotate, and adjusts the position of the anti-collision bar 205. After the second mounting frame 202 drives the anti-collision bar 205 to fit with the car chassis 104, it drives the multiple groups of adjustment blocks 1 206 to slide on the adjustment frame 203. The adjusting block 1 206 drives the welding head 207 to move, and drives the welding head 207 to slide on the adjusting block 1 206. When the welding head 207 reaches the welding position of the automobile chassis 104 and the anti-collision bar 205, the welding head 207 is started, and the welding head 207 welds the automobile chassis 104 and the anti-collision bar 205. After the welding is completed, the clamping plate 204 is driven to reset, and then the mounting frame 202 is driven to reset, and the welding of the anti-collision bar 205 and the automobile chassis 104 is completed.

[0034] After the welding is completed, it is necessary to test the firmness of the welding between the anti-collision bar 205 and the car chassis 104, and drive the detection plate 302 to slide on the mounting frame 301. The detection plate 302 drives the limit head 305 and the push plate 316 to move. The gap between the limit head 305 and the push plate 316 is aligned with the anti-collision bar 205. At this time, the detection column 306 is in contact with the anti-collision bar 205, and the two groups of push plates 316 are driven to slide on the detection plate 302. The two groups of push plates 316 move away from each other. The two groups of push plates 316 push the two groups of anti-collision bars 205 respectively. If the welding between the anti-collision bar 205 and the car chassis 104 is not strong enough, the anti-collision bar 205 will fall off or deviate from the car chassis 104. At this time, the anti-collision bar 205 pushes the detection column 306 to move, and the displacement mover on the detection column 306 detects the abnormal state of the anti-collision bar 205 and alarms, which is handled manually.

When the camera 315 is aligned with the weld between the automobile chassis 104 and the anti-collision bar 205, the camera 315 is started to take pictures and analyze. At the same time, the camera 315 is driven to slide on the annular block 314 to change the position of the camera 315, thereby increasing the shooting range of the camera 315 on the weld and improving the inspection accuracy of the weld.

[0036] During the inspection process, the grinding disc 309 is driven to rotate and grind the surface of the automobile chassis 104 , and the adjustment block 2 308 is driven to slide on the inspection plate 302 to increase the grinding range of the grinding disc 309 and improve the welding effect of other parts on the automobile chassis 104 .
