Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile maintenance equipment, and particularly relates to a drawing device for automobile body repair. Background Technique
[0002] With the rapid development of China's automobile industry and the continuous high-speed growth of the automobile ownership, traffic accidents have increased year by year. When an automobile collides or rubs, the external panel parts and internal structural parts of the automobile body will be dented, deformed, and damaged. After an accident, the vehicle needs to be repaired and restored. Most of the external panel parts of the automobile body can be disassembled, which is convenient for repair or replacement; the internal structural parts of the automobile body are all integrally welded. If they are dented and deformed, the repair process is complex. Because there are multiple layers of reinforcing plates inside the body structural panel, the repair tools cannot reach the deformed position inside. When repairing the dented and deformed position of the body structural steel plate, only a pulling plate can be welded and pulled outwards. Welding and pulling will damage the anti-corrosion layer and the internal molecular structure of the steel plate, reduce the service life of the steel plate, and the repair efficiency is low. Content of the Utility Model
[0003] The purpose of the utility model is to provide a drawing device for automobile body repair to solve the technical problems existing in the prior art.
[0004] In order to achieve the above-mentioned utility model purpose, the technical scheme adopted by the utility model is as follows:
[0005] A drawing device for automobile body repair includes: a drawing device body. For convenient use, the drawing device body is designed to be annular, and a drawing area is formed inside it. A connecting nut is provided at the bottom of the drawing device body. An internal thread is provided inside the connecting nut, and it is threadedly connected with a connecting device.
[0006] Further, the connecting device includes: a bolt connecting body. An external thread is provided on the outside of the bolt connecting body, and a bolt base is provided at the bottom of the bolt connecting body.
[0007] Further, the external thread of the bolt connecting body is adapted to the working size of the internal thread of the connecting nut.
[0008] Further, the drawing device body is made of round steel.
[0009] Further, both the bolt connecting body and the bolt base have a length of 35 mm.
[0010] Compared with the prior art, the utility model has the following beneficial effects:
[0011] The utility model is convenient and fast to operate, can achieve rapid drawing repair, avoids using welding drawing during the repair process, reduces the damage to the steel plate, can retain the original car paint and body structure to the greatest extent, reduces the repair cost, and improves the repair efficiency at the same time.

[0016] In order to make the content of the utility model easier to be clearly understood, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The same parts are denoted by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the words "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific part.
[0017] As Figures 1-3 shown, in this embodiment, a drawing device for repairing an automobile body is provided, including: the main body 1 of the drawing device, the main body 1 of the drawing device is made of round steel, and the diameter of the round steel is 15 mm, the inner diameter length of the main body 1 of the drawing device is 200 mm, and the width is 80 mm; the main body 1 of the drawing device is in a ring shape, and a drawing area 2 is formed inside it. The ring-shaped main body 1 of the drawing device can make the drawing force more evenly distributed on the body part to be repaired, reduce local stress concentration, and thus reduce the risk of further damage to the body; a connecting nut 3 is provided at the bottom of the main body 1 of the drawing device, an internal thread is provided inside the connecting nut 3, and it is threadedly connected with the connecting device 4. The connecting device 4 includes: a bolt connecting body 5, an external thread is provided outside the bolt connecting body 5, a bolt base 6 is provided at the bottom of the bolt connecting body 5, the inside of the bolt base 6 is hollow, and an internal thread is provided inside it. The external thread of the bolt connecting body 5 is adapted to the working size of the internal thread of the connecting nut 3. The lengths of the bolt connecting body 5 and the bolt base 6 are both 35 mm. The model of the bolt connecting body 5 is M8x35, and the bolt base 6 can be M5x35, M6x35, M8x35.
[0018] When in use, the operator selects a suitable bolt base 6 according to the model of the external screw at the position where the body steel plate is dented and deformed. After tightening the pulling device body 1 with the bolt base 6, the bolt base 6 is fastened to the screw at the dented and deformed position, and then the pulling device body 1 is pulled outward by an external force to restore the dented and deformed position to its original shape. It should be noted that during this process, a hammer can be used to cooperate with knocking the deformation to quickly repair the dented and deformed position of the vehicle body.
[0019] The above are only the preferred embodiments of the utility model patent and are not intended to limit the utility model patent. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model patent shall be included within the protection scope of the utility model patent.
