Gas bag polishing tool capable of initiatively distributing abrasive particles

Abstract

The invention provides a gas bag polishing tool capable of initiatively distributing abrasive particles, which comprises a gas bag, a gas transmitting shaft, a gas pump, a liquid-injecting device and a liquid-collecting device, wherein the gas bag comprises a retaining frame and a gas bag shell; the gas transmitting shaft is sleeved in a gas conduction sleeve; the gas conduction sleeve is provided with a through hole; the through hole is communicated with a gas outlet of the gas pump; the gas conduction sleeve is connected with the gas transmitting shaft in a sealing way; the liquid-injecting device is used for filling with polishing liquid; the liquid-collecting device comprises a liquid-collecting disc which is fixedly connected with the gas transmitting shaft and a plurality of liquid-transporting pipes which are used for transporting the polishing liquid; the liquid-collecting disc is provided with an annular liquid-collecting groove and a liquid-flowing channel which is communicated the liquid-collecting groove with the liquid-transporting pipes; the liquid-collecting groove is aligned to a liquid-injecting nozzle of the liquid-injecting device; the liquid-injecting nozzle is connected with the liquid-collecting groove in a sealing way; the gas bag shell is evenly provided with a series of liquid outlets; and the liquid outlets are communicated with outlets of liquid-transporting pipes. The gas bag polishing tool has the advantages that the polishing liquid is automatically added, the abrasive particles are initiatively distributed, and the abrasive dusts are automatically treated during polishing.

Description

technical field [0001] The invention relates to an airbag polishing tool capable of actively distributing abrasive grains. technical background [0002] Before the polished parts are used in industrial occasions, they need to be polished in order to obtain a smooth, uniform and high-quality surface. The manual polishing method has poor working environment, low work efficiency, and unstable surface quality; the traditional rigid polishing method has poor contact collision and poor surface adaptability. The robot-assisted airbag polishing technology gives full play to the advantages of flexible and adjustable rubber airbags and robot assistance, and realizes the precision, efficiency and automation of free-form surface polishing in the mold industry. [0003] At present, the commonly used airbag polishing methods include: adding cerium oxide polishing liquid (abrasive grains) between the polishing head and the workpiece; applying abrasive paste (abrasive grains) on the surfac...

AI Technical Summary

Problems solved by technology

Disadvantages of the former method: the airbag is in close contact with the workpiece; the peripheral speed of the high-speed rotating airbag is large

The above two points will make it difficult for abrasive particles to penetrate, resulting in low polishing efficiency

Disadvantages of the latter method: 1. It takes a long time to replace the abrasive paste and polishing cloth off-line, which reduces the polishing efficiency; 2. The viscosity of the abrasive paste is high, and the abrasive debris is easy to adhere to the polishing cloth, which is difficult to handle and reduces the abrasive grain size. 3. Manually add abrasive paste, which will be applied unevenly to a certain extent, affecting the quality of the polishing surface; 4. Abrasive particles are affected by the rotation of the airbag and are in a passive distribution state, affecting the quality of the polishing surface
