Abstract
The present invention relates to a kind of double-ended tension attachment means, including the spring that rises, depression bar, briquetting, cam and rotating shaft；The spring that rises is sleeve pipe structure, and forms inner conical surface in pipe sleeve upper and lower port internal face；Depression bar one end is inversed taper platform, and the other end is connected with cam rotation；The briquetting is frustum structure, and depression bar is formed through briquetting and is slidably matched；The spring that rises is sleeved on outside depression bar and briquetting；The male cone (strobilus masculinus) of briquetting is slidably matched with the spring upper port conical surface of inboard wall that rises, and the inversed taper platform male cone (strobilus masculinus) of depression bar is slidably matched with the spring lower port conical surface of inboard wall that rises；From the axially extending formation movement joint of jump ring upper and lower port；By rotation cam, briquetting is promoted along depression bar slide downward so that briquetting slides to depression bar inversed taper platform, is extruded by the conical surface so that briquetting and depression bar inversed taper platform extrude the spring internal face that rises, and form tensioner and coordinate, and the spring outer wall that rises expansion realizes that tensioner connects.Present apparatus connection fastening, assembling is simple, simple in construction, and operation is easy.
Description
Technical field
The invention belongs to jig field, is related to a kind of double-ended tension attachment means.
Background technology
In the positioning of machining, it is related to the positioning of parts to be processed, because the trueness error of hole position processing, it is impossible to
Effective guarantee parts to be processed positioning hole is accurately positioned with common alignment pin, can be had certain interval, be caused position error.
The content of the invention
Goal of the invention：In view of the deficienciess of the prior art, the present invention proposes a kind of double-ended tension attachment means.
The technical scheme that the present invention takes is a kind of double-ended tension attachment means, including the spring 1 that rises, depression bar 2, briquetting 3, convex
Wheel 4 and rotating shaft 5；The spring 1 that rises is sleeve pipe structure, and forms inner conical surface in pipe sleeve upper and lower port internal face；
The one end of depression bar 2 is inversed taper platform, and the other end is rotatablely connected with cam 4；The briquetting 3 is frustum structure, and depression bar passes through
Briquetting formation is worn to be slidably matched；The spring 1 that rises is sleeved on outside depression bar 2 and briquetting 3；The male cone (strobilus masculinus) of briquetting 3 and the upper port inwall of spring 1 cone that rises
Face is slidably matched, and the inversed taper platform male cone (strobilus masculinus) of depression bar is slidably matched with the lower port conical surface of inboard wall of spring 1 that rises；From jump ring upper and lower port axial direction
Extension forms movement joint；
By rotation cam, briquetting 3 is promoted along depression bar slide downward so that briquetting slides to depression bar inversed taper platform, by boring
Face extrudes so that briquetting and depression bar inversed taper platform extrude the internal face of spring 1 that rises, and form tensioner and coordinate, and tensioner is realized in the spring outer wall that rises expansion
Connection.
Further, described cam has handle.
Further, described cam is rotatablely connected by rotating shaft 5 and the other end of depression bar 2.
Technique effect：Present apparatus connection fastening, assembling is simple, simple in construction, and operation is easy.
Brief description of the drawings
Fig. 1 is the structural representation of the present apparatus；
Fig. 2 is the practical connection diagram of the present apparatus；
Fig. 3 is the spring structure schematic diagram that rises；
Wherein：1- rise spring, 2- depression bars, 3- briquettings, 4- cams, 5- rotating shafts, the connected pieces of 6- first, 7- second be connected
Part.
