Hydraulic joint used for clamping test piece with superfine pipe diameter

Abstract

A hydraulic joint used for clamping a test piece with a superfine pipe diameter comprises an improved pipeline pressure inlet joint part, a seal clamping part and an improved pipeline pressure outlet joint part, wherein the improved pipeline pressure inlet joint part is located at the left end of the seal clamping part and is in threaded connection with the seal clamping part; and the improved pipeline pressure outlet joint part is located at the right end of the seal clamping part and is in threaded connection with the seal clamping part. The hydraulic joint has the characteristics that a hydraulic pipe joint standard piece is improved so as to be used for clamping the test piece with the superfine pipe diameter, and an internal cavity and an external cavity are sealed simultaneously through alternate combination of gaskets made of different materials; the test piece is clasped through a brass shaft end plug, so that purposes of clamping and detection are completely achieved; and compared with the development of a set of novel clamp with the superfine pipe diameter, the cost is saved, and the production efficiency is improved.

Description

technical field [0001] The invention provides a hydraulic joint for clamping a micro-diameter test piece, in particular relates to a micro-pipe clamping device for a hydraulic system, which is suitable for the detection of tiny workpieces and belongs to the technical field of aerospace science and technology. Background technique [0002] The mechanical clamping device is an important part of the machinery manufacturing industry. The clamping is to clamp the workpiece through the clamping mechanism and convert the clamping force into friction force. Generally, the clamping parts of the machine tool are used for machining. It is involved in aerospace, automotive electronics, electrical instruments, daily kitchen utensils and other fields. For workpieces as large as metric units and as small as millimeters and microns, it is necessary to solve the problem of clamping the workpiece during processing and testing, so as to provide convenience for subsequent processing and testing...

Problems solved by technology

This kind of clamping method is labor-intensive, low in production efficiency, and requires high technical level of workers; but the positioning accuracy is low, and because it often needs to increase the marking process, it increases the production cost; it only needs to use the machine tool accessories with good versatility and tools, so it can be applied to process various surfaces of various parts, especially suitable for single piece and small batch production
