End polishing device for corrugated pipe

Abstract

The invention discloses an end polishing device for a corrugated pipe. The device comprises a round plate, a side support plate, a sanding strip plate, a connecting bolt, a U-shaped plate, an oil control valve, an oil guide pipe, a servo motor, a connecting strip plate, a roller rod, an oil cylinder assembly, hydraulic oil conveying control equipment and a transmission shaft. According to the device, the design is reasonable, two roller rods distributed up and down in the same group are preliminarily attached to the top surface and the bottom surface around a port of the corrugated pipe, and an oil cylinder assembly controlled by the hydraulic oil conveying control equipment is in a contraction state, so that the two roller rods in the same group connected by the connecting strip plate canbe attached to the end to be polished of the corrugated pipe, the whole polishing structure can be wholly fixed, meanwhile, the device can be installed at the ends to be polished of corrugated pipeswith different diameters within a certain range, the servo motor is operated to drive the U-shaped plate connected by the transmission shaft and the side support plate provided with the sanding stripplate to rotate, and the effect that the sanding strip plate polishes the end of the corrugated pipe is achieved.

Description

technical field [0001] The invention relates to an end grinding device, in particular to an end grinding device for bellows, belonging to the technical field of bellows applications. Background technique [0002] Bellows refers to a tubular elastic sensitive element connected by foldable corrugated sheets along the direction of folding and expansion. Bellows are widely used in instruments and meters. The main purpose is as a measuring element of a pressure measuring instrument to convert pressure into displacement or force. The tube wall is thinner, the sensitivity is higher, and the measuring range is tens of Pa to tens of MPa. Its open end is fixed, and the sealing end is in a free state, and the auxiliary coil spring or reed is used to increase the elasticity. Under the action of pressure, it elongates along the length of the pipe, causing the movable end to produce a displacement that has a certain relationship with the pressure. The bellows is often combined with a disp...

[0002] Bellows refers to a tubular elastic sensitive element connected by foldable corrugated sheets along the direction of folding and expansion. Bellows are widely used in instruments and meters. The main purpose is as a measuring element of a pressure measuring instrument to convert pressure into displacement or force. The tube wall is thinner, the sensitivity is higher, and the measuring range is tens of Pa to tens of MPa. Its open end is fixed, and the sealing end is in a free state, and the auxiliary coil spring or reed is used to increase the elasticity. Under the action of pressure, it elongates along the length of the pipe, causing the movable end to produce a displacement that has a certain relationship with the pressure. The bellows is often combined with a displacement sensor to form a pressure sensor whose output is electricity. Sometimes it is also used as an isolation element. Because of the bellows Stretching requires a larger change in volume, so it responds slower than a Bourdon tube

[0003] During the cutting process of the end of the bellows, there will be more burrs or not smooth enough at the end due to the cutting, and the diameter of the bellows will be different, which will cause inconvenience in the selection of equipment for grinding. The traditional grinding structure is not It can be flexibly adjusted and used, and it is not convenient to install on the bellows for use
