Positioning protection structure for tail row corrugated pipe

Abstract

The invention discloses a positioning protection structure for a tail row corrugated pipe. The positioning protection structure comprises an upper supporting arc plate and a lower supporting arc plate, wherein the inner side walls of the upper supporting arc plate and the lower supporting arc plate are each provided with a sliding slot, a slide bar is slidably mounted on the inner side of each sliding slot, and the slide bars are fixedly connected to arc-shaped clamping blocks through metal elastic pieces; the right sides of the upper support arc plate and the lower support arc plate are rotatably connected, air bags are pasted to the middle portions of the inner sides of the upper support arc plate and the lower support arc plate, the air bags communicate with a micro air pump through connecting pipes, the other sides of the air bags are connected with clamping plates in an adhered manner, and the upper ends of the clamping plates are fixedly connected with reset mechanisms. The positioning protection structure is simple in structure, the protective effect on the appearance surface is achieved while the corrugated pipe is positioned, the situation that the corrugated pipe is subjected to extrusion deformation in the positioning process is avoided, and the applicability to the corrugated pipe is stronger.

Description

technical field [0001] The invention belongs to the technical field of bellows processing equipment, and in particular relates to a positioning protection structure for tail row 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. ...

AI Technical Summary

Problems solved by technology

[0003] When processing the bellows in production, the bellows need to be positioned and clamped by the positioning mechanism. The outer wall of the bellows is wavy. In the traditional pressing and positioning process, the raised corrugated part on the outer wall of the bellows The pressure is relatively high, and it is relatively easy to deform, which affects the quality of the product. Therefore, it is necessary to design a positioning protection structure for the tail row bellows
