Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile parts processing, in particular to a precise polishing device for automobile parts. BACKGROUND

[0002] The automobile parts are mostly integrally formed stamping parts during manufacturing. After integrally formed stamping rough machining of the automobile parts, there are many burrs on the circumference of the automobile parts. In order to meet the use requirements, the burrs need to be polished. The existing polishing is basically through high-speed rotation of the grinding wheel to polish one side of the automobile parts. After polishing, the side is changed for polishing. The grinding wheel polishing can improve the polishing efficiency. However, due to the high-speed rotation of the grinding wheel, the polished burrs will splash to the surroundings, and a large amount of dust harmful to human body will be generated. If the operator is not careful, the burrs will get into the eyes and other parts, which will seriously endanger the health of the operator. Moreover, due to the small size of the burrs, it is very inconvenient to collect and transport the burrs.

[0003] In the patent with the publication number CN 113305671B, an intelligent manufacturing automobile parts precise polishing device is proposed. In the patent, a tubular automobile part is placed in the two clamping rings, so that the clamping ring clamps the part through the outside torsion spring. The handle is rotated, so that the sliding block drives the part to move backward, and then contacts the rotating abrasive sheet to polish. The fan two will rotate with the abrasive sheet. In this way, the polished burrs can be concentrated in the grinding groove. The fan one in the top disc blows the burrs in the part to the grinding groove. In this way, the burrs will enter the pressure groove through the through hole, and then the burrs will be extruded into a shape through the pressure plate. The adhesive and other forming agents can be stored in the liquid outlet groove. In this way, the burrs can be more easily formed. In this way, the splashing of the burrs can be reduced, and the collection and transportation of the formed burrs are very convenient. However, the following problems still exist in the patent:

[0004] The existing polishing of the automobile parts is through the rotation of the polishing structure to fix the part on the polishing table. The structure for fixing the part is stationary. The part is clamped and then polished during polishing. The polishing and clamping cannot be performed simultaneously. It is not convenient to adjust and use.

[0005] In view of the above problems, a precise polishing device for automobile parts needs to be designed to overcome the above problems. UTILITY MODEL CONTENTS
