Description

Mounting hole repair device

technical field

The utility model relates to a repairing device for deformation holes on sheet metal parts, in particular to a repairing device for mounting holes with simple repairing process, short working hours and low cost.

Background technique

There are many mounting holes on sheet metal parts, and the mounting holes are prone to deformation during the production process. The main reasons for the deformation of the mounting hole are: (1) during handling; (2) improper operation of the workers; (3) defects in the sheet metal itself when repairing the outer surface of the sheet metal part. Because when repairing the outer surface of the sheet metal part, the installation hole becomes the fulcrum of the leverage force of the repair tool. Under the action of the lever force, the mounting hole cannot provide a large enough reaction force, resulting in varying degrees of deformation of the iron sheet around the mounting hole.

The deformed mounting holes need to be repaired before the parts can be installed. The traditional method of repairing the mounting hole is: (1) use an anvil and an iron hammer, place the anvil on the outer surface of the deformed part of the mounting hole, and then hit the inner surface of the deformed part of the mounting hole with a hammer, so as to remove the unevenness around the mounting hole Correct uneven parts. (2) Use a grinder to grind the outer surface of the mounting hole. (3) Repaint the outer surface of the mounting hole.

The disadvantages of the above-mentioned repairing device are: (1) The required operating space of the repairing tool is relatively large. (2) Since the inner surface of the mounting hole cannot be completely repaired by knocking, the outer surface must be polished, and the thickness of the iron sheet after polishing is reduced, which greatly reduces the repair quality. (3) Due to the collision between the anvil and the outer surface of the installation hole during the process of knocking the installation hole, the paint on the outer surface of the installation hole will be separated, so it needs to be repainted, which increases the repair process, and the paint is easily damaged after repair . The above-mentioned device generally has the problems of complex repair process, long working hours and high cost.

Utility model content

In order to solve the above technical problems, the utility model provides a device for repairing installation holes, including:

Correction assembly; a movable assembly connected with the correction assembly; wherein, the correction assembly includes a first correction member, a second correction member, and a screw rod, the first correction member is sleeved on the screw rod, and the first correction member is sleeved on the screw rod. The straightening piece can move up and down on the surface of the screw, the second straightening piece is connected to one end of the screw, and the first straightening piece and the second straightening piece can be attached to each other; the movable assembly includes a vertical rod and a rotating member, one end of the vertical rod is connected to the other end of the screw rod, and the other end of the vertical rod is connected to the rotating member.

Because the utility model utilizes the first straightening piece and the second straightening piece to cooperate with each other to closely adhere to the outer and inner surfaces of the installation hole, when the first straightening piece and the second straightening piece are rotated, the first straightening piece and the second straightening piece are aligned together. A rolling force is generated around the mounting hole, so that the deformed surface is restored to a flat surface. The device is easy to operate and requires short man-hours; and it can completely repair the surface of the installation hole at one time without grinding the surface; since the correction piece does not collide with the surface of the installation hole, it is not easy to cause the paint on the surface to fall off, so it does not need to be re-aligned The surface is painted. Therefore, the utility model generally solves the problems of complex repair process, long working hours and high cost.
