Description

Technical Field

[0001] The invention relates to the technical field of automobile repair, in particular to an automobile sheet metal repairing device with an auxiliary bracket. Background Art

[0002] Auto sheet metal is a technical means of auto repair. In this respect, auto sheet metal is equal to auto sheet metal repair, which refers to the repair of the car body after a collision, that is, all the work except the anti-corrosion and decorative spraying work on the car body. Such as the analysis of car body damage, the measurement of the car body, the shaping of the car body sheet metal, stretching correction, stress relief welding, and the assembly and adjustment of car body accessories. After a car collision, the car body will be dented. Therefore, in the repair of auto sheet metal, the most common method is to repair the dented parts of the sheet metal. The repair of the dent mainly uses the pulling method to restore the dented position to its original state. When repairing, the dented position of the sheet metal must be fixed first. Commonly used methods include hot melt adhesive bonding and pulling, suction cup adsorption, and welding pull tabs. Then, a pulling tool is used to connect the fixed position. By pulling, an external force is applied to the dented position to restore the dented position to its original state. For example, the authorization announcement number is The Chinese invention patent CN108405657A discloses a car sheet metal repair device, including a support frame, a clamping block is fixedly arranged at the lower end of the support rod, a clamping slot is arranged in the clamping block, a rubber block matching the size of the clamping slot is installed in the clamping slot, a threaded hole is arranged in the middle of the support frame, a screw rod is installed in the threaded hole, a hole slot is opened on the bottom side of the screw rod, a welding rod is inserted in the hole slot, a backing plate is fastened by a fastening screw transversely installed on the screw rod body on the side of the hole slot, a hand wheel is fixedly connected to the top end of the screw rod, a square hole is arranged below the hand wheel, the screw rod is fixed to the depressed position of the sheet metal by welding, and the depressed part is repaired by pulling outward, but this method has the following defects:

[0003] After a car is hit, the collision angles are various. When repairing the dents generated in this way, a better repair effect can be guaranteed only when the angle of the pulling force is consistent with the angle of the collision. However, the current pulling tools cannot assist in adjusting the angle. For example, the above-mentioned automobile sheet metal repair device is fixed with a support rod, so that the pulling angle is single. There are also handheld pulling tools. In this way, the pulling angle depends on the operator's technical adjustment, which is difficult. As a result, the repair is highly dependent on the operator's skills, affecting the final repair effect.

[0052] Embodiment 3:

[0053] See also Figure 1-16, which is the third embodiment of the present invention. This embodiment is based on the above two embodiments. When the present invention is used, the vehicle to be repaired is parked on the side of the bracket mechanism, and a drawing row is glued to the recessed position of the sheet metal by hot melt adhesive, and a metal part is buckled on the drawing row. Then the sliding table 12 moves, and the tool fixing frame assembly 18 adjusts the height position. The end of the drawing rod 23 is manually pulled so that the hook 27 hooks the metal part. Then the angle is fine-tuned by the turntable 13, and the vertical angle of the tool fixing frame assembly 18 is changed by the stretching assembly 19, and the height position of the tool fixing frame assembly 18 is fine-tuned so that the collision force angle formed by the drawing rod 23 and the recess is in the same straight line. Then the first locking bolt 145, the second locking bolt 159 and the third locking bolt 162 are tightened, and at the same time the anti-skid pressure plate 151 presses up to lock the rotating block 118, and the anti-skid pressure strip 1912 presses down to fix the telescopic slave rod 192, and the end is completed. Then, the hook 36 in the pulling structure 3 is hooked onto the hook ring 24 on the pulling rod 23, and the driving motor 38 is started to apply force to the pulling rod 23 to pull the depressed part back to its original state. Then, the pulling rod can be removed to complete the repair. The pulling tool 2 of the present invention is arranged on the bracket mechanism 1, and the pulling tool 2 is used for pulling operation, and the pulling structure 3 is used to provide pulling power. The movement of the sliding table 12 is convenient for carrying the pulling tool 2 to move to the working position, and the horizontal angle direction of the pulling tool 2 is changed by the rotation of the turntable 13. The stretching component 19 can be extended and retracted to change the length, and a pulling force is generated on the tool fixing frame component 18, thereby changing the vertical angle direction of the pulling tool 2 carried thereon. In this way, when pulling, the force direction of the pulling tool 2 can be made consistent with the direction of the collision force generated by the depression, and the pulling effect is better. There is no need for manual operation to fine-tune the angle, and it does not rely on the skills of the repair personnel, so that the depression repair effect is better.
