Description
Technical field
The utility model relates to pipe fitting manufacture field, particularly a kind of for clamp device in pipe fitting.
Background technology
In the process of pipe fitting, usually use clamping device to be fixed by pipe fitting, then process operation is carried out to pipe fitting.As bent tube technique is widely used in mechanical manufacturing field, the method for clamping of existing clamp system adopts the additional compact form of pipe end, and what this method needs were certain steps up area, and the tubular length of needs is long.And be hollow metal structure because pipe fitting is mostly, when the inwall of gear pipe fitting is thinner, clamp system very easily makes pipe fitting towards its inner generation flexural deformation when clamping pipe fitting, have influence on the reliability of cylindrical shell clamping on the one hand; Cylindrical shell is made to cause scrapping of cylindrical shell because of distortion on the other hand.And retained part cannot be processed, it is also a kind of waste.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of compact conformation is provided, can be good at realizing pipe fitting in clamping, pipe fitting difficult deformation, should not cause scrap for clamp device in pipe fitting.
The technical scheme in the invention for solving the above technical problem is: a kind of for clamp device in pipe fitting, comprise the collet for matching with the inwall of pipe fitting, described collet is the cone shape being provided with hollow cavity, and the periphery of described collet is circumferentially provided with many profile grooves axially arranged, it also comprises the inner support being sleeved on described collet inner chamber, interior holder, with described in the liner base that is slidably matched of holder, the pushing sleeve of the inner clip holder being connected to the tailstock of bending machine and the push cylinder being fixed on tailstock, described interior holder, liner base holder is all placed in the inner chamber of described pushing sleeve, described collet end is fixedly connected on one end of interior holder by flange, and the other end of described interior holder is fixed on described inner clip holder, the end of described inner support is fixed on one end of described liner base, and the other end of described liner base is fixedly connected by multiple contiguous block of arranging along excircle and described pushing sleeve.
Compared with prior art, the utility model has the advantage of: this interior clamp device being used for pipe fitting comprises the collet for matching with the inwall of pipe fitting, collet is the cone shape being provided with hollow cavity, and the periphery of collet is circumferentially provided with many axial profile grooves, it also comprise the inner support being sleeved on collet inner chamber, interior holder, the liner base be slidably matched with interior holder, be connected to bending machine tailstock inner clip holder and be fixed on the pushing sleeve of push cylinder of tailstock, interior holder, liner base holder are all placed in the inner chamber of pushing sleeve; Collet end is fixedly connected on one end of interior holder by flange, and the other end of interior holder is fixed on inner clip holder; The end of inner support is fixed on one end of liner base, and the other end of liner base is fixedly connected by multiple contiguous block of arranging along excircle and pushing sleeve.During use, tubing is enclosed within collet, then the push cylinder of tailstock is released, drive pushing sleeve and liner base to advance, and drive inner support to move ahead, strut collet, thus reach the object of clamping tubing; Push cylinder is return, then collet is by elastic shrinkage own, unclamps pipe fitting.This be used for the inner clip apparatus structure of pipe fitting compact, can be good at realizing clamping in pipe fitting, pipe fitting difficult deformation, should not cause and scrap.
As preferably, the excircle of described pushing sleeve is provided with multiple mounting groove for accommodating described contiguous block, and the other end of described liner base is provided with the cannelure for chimeric described contiguous block, and described contiguous block is fixedly connected with described pushing sleeve by bolt.
As preferably, the quantity of described contiguous block is 3, and described 3 contiguous blocks are uniformly distributed along the outer circumference surface of described pushing sleeve.
As preferably, the end face of described pushing sleeve near one end of collet is provided with cover plate, and described cover plate by screw be fixedly connected on described in the end face of holder.
As preferably, described flange is fixedly sleeved on the end of described flange, and described flange is fixed on described cover plate between interior holder.
