Description
Technical field
The utility model relates to a kind of clamping device, and especially a kind of slotted hole two ends elastic clamp device belongs to technical field of machining.
Background technology
At processing slotted hole class part, when need be to the endoporus of workpiece and an end face location, this must take reliable locate mode.The locate mode of prior art comprises:
1, three-jaw back strut one end endoporus; Described locate mode is feasible to short cylinder, but for long cylinder the risk of vibrating and chatter mark occurring is arranged then, and the phenomenon of clamping deformation more can occur for part in the thin-walled.
2, do mandrel always, put workpiece, the end face nut compresses; Described mode is feasible for roughing, owing to be the mandrel location, belongs to matched in clearance, so can produce cylindrical and endoporus decentraction phenomenon, is infeasible for accurately machined workpiece.This installation way requires blank aperture unanimity (tolerance range is very little), and this has just increased production cost.
Therefore, tolerance higher requirement when above-mentioned two kinds of existing locate modes all can not satisfy slotted hole class part processing can not satisfy the needs of processing location.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of slotted hole two ends elastic clamp device is provided, and it is simple in structure, and is easy to install, and the positioning accuracy height satisfies the needs to the processing of slotted hole class workpiece, and is safe and reliable.
The technical scheme that provides according to the utility model, described slotted hole two ends elastic clamp device comprises mandrel, and an end of described mandrel is provided with fixedly connected left tapered sleeve, mandrel is equipped with right tapered sleeve corresponding to the other end that left tapered sleeve is set by locking nut, and described right tapered sleeve can move on mandrel; The corresponding end that links to each other with right tapered sleeve of described left tapered sleeve is provided with collet, and the outer peripheral face of described collet is provided with a plurality of equally distributed elastic opening grooves; Described left tapered sleeve all stretches in the collet with the end that right tapered sleeve links to each other with collet.
Link to each other by back-moving spring between the corresponding adjacent end of described left tapered sleeve with right tapered sleeve.Described mandrel is provided with the stop pin that is used to prevent right tapered sleeve rotation.
On the described collet workpiece is installed, the inwall of described workpiece closely contacts with collet.The axis of described workpiece and the axis of mandrel are located along the same line.
Advantage of the present utility model: an end of mandrel is provided with left tapered sleeve, and the other end is provided with right tapered sleeve by locking nut, and right tapered sleeve can move on mandrel; The end of left side tapered sleeve and right tapered sleeve is all stretched in the collet, and workpiece is installed on the collet; When screwing locking nut, can promote right tapered sleeve left the direction of tapered sleeve move, thereby collet is expanded outwardly, the outer wall of collet and workpiece be closely contact mutually, reaches the purpose of fastening installation workpiece; When unclamping locking nut simultaneously, left tapered sleeve and right tapered sleeve reset under the effect of back-moving spring, and collet shrinks, and is convenient to take off the workpiece that machines; Effectively, reliable fixation workpiece, improve the stability of crudy greatly; Collet is very low for the hole tolerance requirement of machining blanks, has reduced manufacturing cost; The clamping facility is increased work efficiency greatly; The scope of application is wider, and fricton-tight friction, and the life-span is longer; Simple in structure, manufacturing cost is lower.
Description of drawings
Fig. 1 is user mode figure of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in Figure 1: the utility model comprises that left tapered sleeve 1, mandrel 2, elastic opening groove 3, workpiece 4, right tapered sleeve 5, stop pin 6, locking nut 7, back-moving spring 8 are collet 9.
As shown in Figure 1: described left tapered sleeve 1 is fixedly installed in the left end of mandrel 2, and the right-hand member of mandrel 2 is equipped with right tapered sleeve 5 by locking nut 7, and right tapered sleeve 5 can move on mandrel 2.Left side tapered sleeve 1 is located along the same line with the axis of right tapered sleeve 5 and the axis of mandrel 2; When screwing locking nut 7, can promote right tapered sleeve 5 and on mandrel 2, move.In order can to reset, link to each other by back-moving spring 8 between left tapered sleeve 1 and right tapered sleeve 5 corresponding adjacent ends to left tapered sleeve 1 and 5 of right tapered sleeves.A left side is provided with collet 9 between tapered sleeve 1 and right tapered sleeve 5 corresponding adjacent ends; Left side tapered sleeve 1 all stretches in the collet 9 corresponding to the end that links to each other with collet 9 with right tapered sleeve 5, and closely contacts mutually with collet 9.Collet 9 is provided with some elastic opening grooves 3 along collet 9 distribution of lengths, and when collet 9 was squeezed, collet 9 is distending uniformly.In order to prevent the rotation of right tapered sleeve 5, on mandrel 2, be provided with stop pin 6; Right tapered sleeve 5 is provided with locating hole, and an end of stop pin 6 stretches out outside the locating hole, thereby can guarantee that right tapered sleeve 5 can be along the moving axially of mandrel 2, and can not rotate.
As shown in Figure 1: during use, workpiece 4 is installed on the collet 9, and the internal diameter of the external diameter of collet 9 and workpiece 4 is complementary.After workpiece 4 is installed, screw locking nut 7, the continuous turn of locking nut 7, the right tapered sleeve 5 of locking nut 7 meeting promotions moves along the axial direction of tapered sleeve 1 left of mandrel 2.Because left tapered sleeve 1 all stretches in the collet 9 with the end of right tapered sleeve 5, left side tapered sleeve 1 can push collet 9 with right tapered sleeve 5, make collet 9 evenly outside distendings, behind collet 9 distendings, the outer wall of collet 9 closely contacts mutually with the inwall of workpiece 4, thereby reaches the purpose of fastening installation workpiece 4.The axis of the axis of workpiece 4 and mandrel 2 is located along the same line.After workpiece 4 was fixedly mounted on the mandrel 2, workpiece 4 linked to each other with slewing, thereby process equipment can be processed accordingly to workpiece 4.After workpiece 4 machines, unclamp locking nut 7; After locking nut 7 unclamped, right tapered sleeve 5 resetted under the effect of back-moving spring 8 with left tapered sleeve 1.After right tapered sleeve 5 resetted with left tapered sleeve 1, the squeezing action power that collet 9 is subjected to disappeared, and collet 9 resets, thereby can be convenient to take off workpiece 4, provides preparation for carrying out installing and using of next workpiece 4.
One end of the utility model mandrel 2 is provided with left tapered sleeve 1, and the other end is provided with right tapered sleeve 5 by locking nut 7, and right tapered sleeve 5 can move on mandrel 2; Left side tapered sleeve 1 all stretches in the collet 9 with the end of right tapered sleeve 5, and workpiece 4 is installed on the collet 9; When screwing locking nut 7, can promote right tapered sleeve 5 left the direction of tapered sleeve 1 move, thereby collet 9 is expanded outwardly, the outer wall of collet 9 and workpiece 4 be closely contact mutually, reaches the purpose of fastening installation workpiece 4; When unclamping locking nut 7 simultaneously, left tapered sleeve 1 resets under the effect of back-moving spring 8 with right tapered sleeve 5, and collet 9 shrinks, and is convenient to take off the workpiece 4 that machines; Effectively, reliable fixation workpiece 4, improve the stability of crudy greatly; Collet 9 is very low for the hole tolerance requirement of machining blanks, has reduced manufacturing cost; The clamping facility is increased work efficiency greatly; The scope of application is wider, and fricton-tight friction, and the life-span is longer; Simple in structure, manufacturing cost is lower.
