Hydraulic suction seamless repair machine for car shell

Abstract

A hydraulic suction seamless repair machine for a car shell belongs to the field of car shell repair equipment and particularly relates to a hydraulic suction repair machine for a car shell. The hydraulic suction seamless repair machine is characterized in that a power mechanism comprises a piston rod (5), as well as an upper hydraulic mechanism and a lower hydraulic mechanism which are vertically connected into a whole through a connecting part (6), wherein the piston rod (5) passes through the connecting part (6) to penetrate the upper hydraulic mechanism and the lower hydraulic mechanism; the interior of the upper hydraulic mechanism is divided into a water injection cavity (22) at the upper part and an air cavity (23) at the lower part through a sealing device at the top end of the piston rod (5); one side of the water injection cavity (22) is connected with a water injection mechanism; a circulatory venthole (26) is formed in the hydraulic cylinder wall on one side of the air cavity (25); a sucker (1) is communicated with the water injection cavity (22) through a through hole (23). The hydraulic suction seamless repair machine adopts the evacuating method that water is injected into the sucker at first and then discharged, and the hydraulic power mechanism provides a stable suction force to complete repair, so that the suction force is strong and the repair effect is remarkable.

Description

technical field [0001] The utility model relates to a hydraulic suction non-mark repairing machine for a car shell, which belongs to the field of vehicle shell repairing equipment, and specifically relates to a hydraulic suction repairing machine for a vehicle shell.

Problems solved by technology

[0002] There are often dents on the surface of the car due to bumps. At present, the common repair methods are mainly divided into two types: traditional and new. The traditional repair method needs to disassemble the dent parts first, and then repair them by knocking , this method is not only time-consuming and labor-intensive, but also needs to knock off the paint on the original shell during repair, which is not ideal for the repair effect of the vehicle.

[0003] In addition, there is a new type of repair method, that is, the method of sucking out the pit through the suction force of the suction cup. This method does not need to knock off the paint on the original shell, and can directly repair the vehicle shell. Compared with the traditional repair method It is relatively time-saving and labor-saving, but most of the current suction repair devices use a vacuum pump to first vacuum the inside of the suction cup, and then pull the suction cup to suck out the pit through the suction force generated by the suction cup. The suction force is small, not enough to suck out the pit, so that the adsorption between the suction cup and the surrounding pit is not tight enough, resulting in unsatisfactory suction effect of the pit. Therefore, the operation of the suction repair method of the existing structure is not stable, and the repair cannot be guaranteed Effect
