Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automatic polishing of vehicle frame, and particularly relates to an automatic polishing device for vehicle frame. BACKGROUND

[0002] The skid of an automobile production workshop is a jig for bearing automobile products and is widely used on skid conveying lines in welding, painting and final assembly workshops;

[0003] During the spraying process of the automobile frame in the painting workshop, the sprayed paint may drop onto the bottom of the skid, and if it is not cleaned for a long time, the paint will accumulate and become thicker, which will affect the use efficiency.

[0004] Nowadays, the traditional automobile frame polishing device usually uses manual method to clean the accumulated paint on the surface of the frame, which has low working efficiency and produces dust during polishing, which is adsorbed by people and causes harm to the human body. With the progress of technology, automatic polishing devices appear, but the traditional automatic polishing devices cannot effectively satisfy the polishing effect of the frame during the working process, and can only polish the stationary frame, which affects the working efficiency of the automobile frame and reduces the production efficiency of the production workshop.

[0005] According to the search, the patent with the patent number CN202221645460.6 discloses a polishing device for the bottom of the face paint skid in the painting workshop; the steel wire brush roller is arranged at the connection position close to the two adjacent roller beds and opposite to the rotating direction of the roller on the roller bed; during the conveying process of the skid on the roller bed, the steel wire brush roller rotates to polish the bottom surface of the skid. The driving motor is installed at the middle connection position of the adjacent two roller beds, and the driving motor and the roller shaft of the steel wire brush roller are driven by the belt;

[0006] In the above-mentioned patent, the roller shaft is driven to rotate by the driving motor during the polishing process of the skid, so that the steel wire brush wheels at both ends of the roller shaft realize the polishing process of the bottom of the skid. Although the polishing effect can be achieved, the top of the skid supports the frame during the spraying process in the spraying production workshop, and the paint may be sprayed on the side wall of the skid during the spraying process. The paint does not appear on the bottom of the skid, so the bottom of the skid does not need to be polished. Therefore, the polishing device in the above-mentioned patent has certain defects during the polishing process of the skid. UTILITY MODEL CONTENTS
