Abstract
The utility model discloses a cartridge clip formula frock, including hollow cylinder (1), the one end of cylinder (1) is clamping part (2), and the other end is elasticity portion (3), the external diameter of elasticity portion (3) is less than the external diameter of clamping part (2), be provided with centre gripping hole (4) in clamping part (2), be provided with shrinkage joint (5) on cylinder (1), the oral area of shrinkage joint (5) follow clamping parts (2) extends to the middle part of elasticity portion (3). Cartridge clip formula frock, the external diameter specification of its clamping part and elasticity portion is unified, and collet chuck's specification phase -match on clamping part external diameter specification and the lathe when processing the product of different specifications, only needs to change cartridge clip formula frock can, need not the collet chuck on the lathe, labour saving and time saving, the aperture in centre gripping hole is identical with the product external diameter of clamping, can not press from both sides the product and warp and can not cause to press from both sides to the product external diameter and hinder.
Description
Technical field
The utility model relates to a kind of cartridge-type frock, belongs to part processing technique field.
Background technology
Process that some materials are softer, cylindrical smoothness requirements is higher and cylindrical does not allow the miscellaneous goods crushed time, existing mounting means is usually directly be arranged on lathe by product by scroll chuck, the first-class frock of spring clip, easily like this crushed or deformed, being unfavorable for the fineness ensureing circle product external.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of cartridge-type frock, and the product of institute's clamping can be avoided to be crushed or be out of shape, simple to operation.
The purpose of this utility model is achieved through the following technical solutions:
A kind of cartridge-type frock, comprise hollow cylinder, one end of described cylinder is clamping part, the other end is elastic portion, the external diameter of described elastic portion is less than the external diameter of clamping part, be provided with clamping hole in described clamping part, described cylinder is provided with shrinkage joint, described shrinkage joint extends to the middle part of elastic portion from the oral area of clamping part.Described clamping part is used for the collet clamping with lathe, the match specifications of the external diameter specification of clamping part and the collet of lathe, clamping hole is for clamping product to be processed, the product external diameter that aperture specification and the generation of clamping hole process matches, when processing the product of different size, only need change this frock, without the need to the collet on lathe, time saving and energy saving.
Preferably, the oral area of described clamping part is provided with positioning step.
Preferably, the quantity of described shrinkage joint is four, is evenly arranged on described cylinder.
Preferably, described elastic portion inside arranges springhole, and described clamping hole is communicated with by through hole with springhole, and the aperture of described clamping hole is greater than the aperture formation confined planes of through hole.Confined planes plays position-limiting action at axial direction, is convenient to the product that clamping is processed.
Preferably, the wall thickness of described elastic portion is 1 ~ 2mm.Make the elasticity of elastic portion moderate, both can not cause not clamping product and workpiece is skidded because elasticity offset collet clamping force too greatly, also can not open in the posttension of converted products and can not get product, clamping and the taking-up of product be quite convenient
Preferably, the roughness≤Ra0.8 of described clamping hole.Ensure clamping hole extra coarse degree, prevent clamped product surface from being crushed.
Preferably, described cylinder adopts 45# steel or CrWMn steel to do.Draw materials easily, economical and practical, and durable in use, not easy to wear.
Compared with prior art, the beneficial effects of the utility model:
1, cartridge-type frock described in the utility model, the external diameter uniform specification of its clamping part and elastic portion, the match specifications of clamping part external diameter specification and lathe upper grip, when processing the product of different size, only need change cartridge-type frock described in the utility model, without the need to the chuck on lathe, time saving and energy saving;
2, cartridge-type frock described in the utility model, the aperture of its clamping hole and the product external diameter of institute's clamping match, and product clip can not be out of shape and can not cause product external diameter to crush;
3, material of the present utility model easily obtain, economical and practical, processing technology is simple, mounts and dismounts convenient and swift.

Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, utility model is described further:
Composition graphs 1 and Fig. 2, a kind of cartridge-type frock of the utility model, adopt the hollow cylinder 1 of 45# steel or CrWMn steel integral type processing and fabricating, one end of cylinder 1 is elastic portion 3, the other end is clamping part 2, the external diameter of elastic portion 3 is less than the external diameter of clamping part 2, described clamping part 2 is inner for the collet being arranged on lathe, the external diameter of clamping part 2 and the collet of lathe match, uniformly on cylinder 1 be provided with four shrinkage joints 5, described shrinkage joint 5 extends to the middle part of elastic portion 3 from the oral area of clamping part 2, the oral area of clamping part 2 is provided with positioning step 6.
The inside of described clamping part 2 arranges clamping hole 4, described elastic portion 3 inside arranges springhole 7, described clamping hole 4 is communicated with by through hole 8 with springhole 7, and the wall thickness that described elastic portion 3 and springhole 7 are formed is 1 ~ 2mm, and the aperture of described clamping hole 4 is greater than the aperture formation confined planes 9 of through hole 8.The aperture specification of described clamping hole 4 and the external diameter of clamped product match, and the roughness≤Ra0.8 of clamping hole 4 prevents clamped product surface from being crushed.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
