Description

Technical Field

[0001] The present invention belongs to the technical field of automobile parts processing, and particularly relates to an automobile parts spraying device. Background Art

[0002] With the improvement of people's living standards, people's consumption of automobiles is increasing, and the market for automobile parts has become larger and larger. In recent years, automobile parts manufacturing plants have also been developing rapidly. Automobile parts are various units that make up the whole automobile and a kind of product serving the automobile. Its production and processing process includes spraying. Among them, the process of spraying one or more layers of paint on the surface of automobile parts products is the most extensive. Spraying appropriate paint on automobile parts can not only play a protective role and extend its service life, but also improve the appearance quality of automobile parts.

[0003] The Chinese invention patent with the publication number of CN113289794A discloses an automobile parts spraying device, which includes a processing table. A support frame is connected to the processing table. A first sliding cylinder is arranged on the support frame. An up-and-down moving member is arranged in the upper part of the first sliding cylinder. The up-and-down moving member is connected with a nozzle through a connecting block. The up-and-down moving member is used to control the up-and-down movement of the connecting block. A triangular inclined plate is connected to the side wall of the nozzle through a third connecting frame. A limiting rod is arranged below the triangular inclined plate. The limiting rod is connected to the processing table through a rotating shaft. The limiting rod is arranged on the side wall of the rotating shaft. A torsion spring is fixedly connected to the rotating shaft. The other end of the torsion spring is fixedly connected to the processing table. A first receiving plate is connected to the side wall of the rotating shaft through a second support frame. A first receiving groove is formed in the first receiving plate. The first receiving groove is located below the nozzle. The above-mentioned patent is convenient for spraying automobile parts, and is convenient for preventing the spraying liquid from falling while realizing the air-drying treatment of automobile parts.

[0004] However, the above-mentioned patent has the following deficiencies: 1. The above-mentioned patent sprays the workpiece by lowering the nozzle and sending the paint to the nozzle through a pump body. This spraying method has a limited spraying range and cannot spray the specified position at the top of the workpiece. Moreover, the above-mentioned patent also uses the first receiving plate to prevent the excess paint on the nozzle from falling onto the already sprayed automobile parts. This prevention method often occupies the space on the top of the processing table due to the large volume of the component driving the rotation of the first receiving plate.

[0005] 2. The above-mentioned patent makes the first connecting frame and the second connecting frame approach each other by meshing the first gear with the first rack and the second rack, so as to clamp and fix automotive parts of different lengths. However, in this clamping method, the distances between the first connecting frame and the automotive parts and between the second connecting frame and the automotive parts cannot be adjusted separately. When the distances between the first connecting frame and the parts and between the second connecting frame and the parts are different, it will cause the parts to be displaced easily on the conveyor belt during clamping, and thus the bottom of the parts is prone to wear.
