Abstract

The invention discloses an adjustable bellows inner wall polishing machine, which comprises a motor casing, a polishing motor is fixedly connected to the inside of the motor casing, a polishing rotating shaft is fixedly connected to the output shaft of the polishing motor, and a telescopic device is fixedly connected to the surface of the polishing rotating shaft The end of the telescopic device far away from the polishing shaft is fixedly connected with a polishing sheet. The telescopic device includes a fixed housing. The bottom of the inner wall of the fixed housing is fixedly connected with a telescopic spring. A telescopic limiting slot is provided on the top, and the side of the telescopic limiting plate runs through the telescopic limiting slot and extends to its interior. By setting the telescopic device, the effect of adjusting the polishing radius is realized, which can be adjusted according to bellows with different radii, so it is suitable for bellows with different radii, greatly reduces the use cost, is economical and environmentally friendly, and has small volume, simple structure, Easy to operate.

Description

technical field [0001] The invention relates to the technical field of bellows, in particular to an adjustable inner wall polishing machine for bellows. Background technique [0002] Bellows refers to a tubular elastic sensitive element connected by foldable corrugated sheets along the direction of folding and stretching. Bellows are widely used in instruments and meters, and their main purpose is as a measuring element of a pressure measuring instrument to convert pressure into displacement or force. The bellows has a thinner wall and higher sensitivity, and the measurement range is tens of Pa to tens of MPa. Its open end is fixed, and the sealed end is in a free state, and the auxiliary coil spring or reed is used to increase the elasticity. When working, under the action of internal pressure, it is elongated along the length of the pipe, so that the movable end produces a displacement that has a certain relationship with the pressure. The movable end drives the pointer...
