Description

Technical Field

[0001] This utility model relates to the field of automotive polishing technology, and more specifically, to a polishing device for automotive repair. Background Technology

[0002] Automotive repair and polishing refers to the process of repairing and refurbishing the exterior of a car. Over time, various problems may appear on the exterior of a car, such as minor scratches, oxidation, and loss of paint gloss. The purpose of automotive repair and polishing is to remove these surface defects and restore the car's shine and appearance.

[0003] When polishing automotive parts, the parts are usually placed on a polishing table and the surface is polished using a moving polishing disc. In actual use, the rapid friction between the polishing disc and the workpiece generates a lot of debris. If this debris is not removed in time, it will remain on the polishing table, which will not only damage the surface of the workpiece, but also the small dust impurities can be easily inhaled by workers, endangering their health. Therefore, a polishing device for automotive repair is provided. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a polishing device for automobile repair, which aims to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a polishing device for automobile repair, including a vertical tube, on which a flow guiding polishing component is provided;

[0006] The flow guiding and polishing assembly includes a polishing disc disposed at the bottom of the vertical tube, and a reinforcing ring disposed on the outer side of the polishing disc. The reinforcing ring is located at the bottom of the vertical tube and is rotatably connected to the vertical tube.

[0007] The bottom of the reinforcing ring has several flow dividers, and each flow divider has a polishing ring at its bottom end.

[0008] Optionally, in one possible implementation, the outer side of the throwing disc is provided with several guide frames, the top of the throwing disc is provided with several suction plates, the top of the throwing disc is provided with through holes, and each of the through holes is connected to the guide frames. The top of the vertical pipe is provided with a motor for driving the throwing disc to rotate, and a filter for filtration is provided on one side of the top of the motor. Each of the multiple diversion plates is provided with a notch on one side, and the throwing disc is located in the notch. The throwing disc and the reinforcing ring are detachably connected by bolts. The multiple diversion plates are all inclined, and a waste slag extraction port is formed between each two adjacent diversion plates.

[0009] The technical effects and advantages of this utility model are as follows:

[0010] The polishing disc works in conjunction with polishing rings at the bottom of multiple inclined flow dividers to form a multi-zone collaborative polishing structure. When the polishing disc rotates, the reinforcing ring drives the flow dividers and polishing rings to rotate synchronously, making the polishing force distribution more uniform. This effectively removes scratches, oxide layers, and other defects from the surface of automotive workpieces, improving the gloss and aesthetics of the polished surface.

[0011] The guide frame on the outside of the polishing disc guides the flow of polishing debris through centrifugal force. It connects with the through hole at the top of the polishing disc to form a debris collection channel. At the same time, the waste extraction port between adjacent flow dividers can specifically adsorb debris from the edge of the workpiece. Combined with the enhanced airflow adsorption effect of the suction plate, the debris can be quickly discharged, avoiding secondary damage caused by debris residue on the workpiece surface. It can also filter the extracted dusty airflow, effectively trapping fine dust impurities, preventing them from being inhaled by workers, reducing health risks, and improving the working environment.

[0022] Filter 10: The model can be a HEPA filter, whose air inlet is connected to the airflow channel in the vertical pipe 1, and is used to filter dust and debris generated during polishing.

[0023] like Figure 3 As shown, a throwing plate 2 is provided at the bottom of the vertical pipe 1. The throwing plate 2 can be made of polyurethane. Several guide frames 6 are evenly distributed on its outer circumference to guide the flow of debris. Several suction plates 7 are distributed on the top surface of the throwing plate 2. The suction plates 7 are arc-shaped plates and form an inclined angle with the top surface of the throwing plate 2 to enhance the airflow adsorption effect. A through hole 8 is also provided in the central area of ​​the top of the throwing plate 2. Each through hole 8 is connected to the guide frame 6 through the flow channel inside the throwing plate 2 to form a debris extraction channel.
