Abstract
The invention discloses an elastic sizing fixture. The elastic sizing fixture comprises a seat body, wherein inner cone sleeves are respectively embedded at the upper and lower ends of the seat body; an elastic sizing cone sleeve is arranged at the inner side of the inner cone sleeve; the elastic sizing cone sleeve located on the upper part of the inner side of the inner cone sleeve is connected with a pressure plate; and the elastic sizing cone sleeve, the inner cone sleeves and the interior of the seat body constitute a cavity for placing a workpiece. According to the invention, the elastic sizing cone sleeve is arranged inside the seat body, so that the workpiece can be correctly located, the precision of workpiece cone teeth is ensured when rolling processing is carried out; and by utilizing the elasticity of the elastic sizing cone sleeve, the workpiece can be conveniently assembled and disassembled, and the workpiece can be easily taken out in no need of beating with a hammer.
Description
Technical field
The present invention relates to field of machining, relate to a kind of anchor clamps of thin-walled awl tooth tooth cover rolling and processing specifically.
Background technology
In the prior art during with cold breakdown platen press processing awl tooth; Generally be with the method that adopts the fixed cover sizing; But workpiece dilates through external diameter after the roll extrusion easily, and just can cause workpiece and calibration sleeve stuck this moment, and the processing personnel often strike with a hammer and could take out workpiece; So not only can reduce operating efficiency, also very likely when beaing, destroy workpiece.In addition, during with the fixed cover sizing, cooperate too pine or the too tight geometric eccentricity that all very likely causes workpiece, influence precision.
Summary of the invention
The object of the invention will provide a kind of elasticity sizing anchor clamps exactly, and these anchor clamps not only can guarantee the precision of diameter of work, and workpiece is loaded and unloaded easily, avoids beaing workpiece is damaged.
The present invention adopts following technical scheme:
A kind of elasticity sizing anchor clamps; Comprise pedestal,, elasticity sizing tapered sleeve is set in the inner conical drogue inboard at the built-in inner conical drogue of the two ends up and down of pedestal difference; Superposed elasticity sizing tapered sleeve is connected with platen, the inner cavity that forms place work piece of elasticity sizing tapered sleeve, inner conical drogue and pedestal.
Further, the body end face of elasticity sizing tapered sleeve body end face and inner conical drogue fits.
Further, the face that fits of inner conical drogue and elasticity sizing tapered sleeve is the inclined-plane.
The invention has the beneficial effects as follows:
Through at pedestal set inside elasticity sizing tapered sleeve, workpiece is accurately located, guarantee the precision of workpiece awl tooth when rolling and processing, also can utilize its elasticity, make workpiece loading and unloading convenient efficient, needn't beat with iron hammer again and can easily take out workpiece.
Description of drawings
Fig. 1 is the sketch map of the embodiment of the invention 1;
The specific embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
When using these elasticity sizing anchor clamps; At first workpiece 4 is put into the internal cavities of these anchor clamps; Platen 5 is under the effect of vertical force; Press down the elasticity sizing tapered sleeve 3 that is positioned at workpiece top and cause the both ends of the surface of the elasticity sizing tapered sleeve 3 that is positioned at the bottom to be combined closely with the end face of workpiece 4 and pedestal 1 respectively, the internal diameter of elasticity sizing tapered sleeve 3 contracts to the location diameter of workpiece 4 simultaneously, roll extrusion awl tooth processing beginning; After treating that rolling and processing finishes, platen 5 is upwards lifted, elasticity sizing tapered sleeve 3 dilates under the effect of self elastic force and rises along the conical surface of inner conical drogue 2, makes elasticity sizing tapered sleeve 3 and workpiece 4 external diameters break away from, and can take out workpiece easily this moment.
