Abstract
A kind of fixture, is made up of right baffle-plate, left sleeve, housing screw, connecting plate, right sleeve, rhombus pin, screw, right baffle plate, taper bolt; Described left sleeve one end is connected with described right baffle-plate, and the other end is connected with housing screw; Described connecting plate is a rectangle iron block, and its one end is connected with right baffle-plate, and one end is connected with right baffle plate in addition; Described rhombus pin embeds in left and right sleeve respectively; Described taper bolt embeds in left and right baffle plate respectively; Described left and right sleeve is the major part of this fixture, and be the sleeve of two long 150mm, the eccentric 1mm of inside and outside circle respectively, can shape rear incision is two pieces simultaneously, as the main location of workpiece.The utility model has higher efficiency to during tailstock eccentric bushing, and machining accuracy is higher.
Description
Technical field
The utility model relates to field of machining, particularly relates to a kind of tooling device.
Background technology
Fixture is in metal cutting process, in order to determine the location of workpiece exactly, and it is clamped securely, to connect processed process equipment.Its Main Function is: the crudy reliably ensureing workpiece, improves working (machining) efficiency, reduces labor intensity, give full play to and expand the processing performance of lathe.Therefore, fixture occupies an important position in machine-building.The kind of fixture is a lot, as being divided into following four kinds of fundamental types by the classification of its range of application: universal fixturing, special fixture, modular fixture and built-up jig.Although range of application is different, fixture is made up of five parts mostly: setting element and positioner, clamping device, tool setting and the device such as induction element, clamp body.At present, the fixture used in process of production is common bench vice mostly.Common bench vice adopts screw thread clamp system, although screw thread clamp system structure is simple, reliable clamping, but use the remarkable shortcoming that pinching action is slow, work-handling is time-consuming, inefficiency is it, frequently replacing with particularly at different size workpiece, the number of turns of rotation is more.
Utility model content
In view of in prior art, process eccentric work piece time easily cause waste and working (machining) efficiency is lower.The purpose of this utility model is to provide a kind of special fixture processing eccentric work piece.
In order to achieve the above object, technical solution adopted in the utility model is as follows:
A kind of fixture, is made up of right baffle-plate, left sleeve, housing screw, connecting plate, right sleeve, rhombus pin, screw, right baffle plate, taper bolt; Described left sleeve one end is connected with described right baffle-plate, and the other end is connected with housing screw; Described connecting plate is a rectangle iron block, and its one end is connected with right baffle-plate, and one end is connected with right baffle plate in addition; Described rhombus pin embeds in left and right sleeve respectively; Described taper bolt embeds in left and right baffle plate respectively;
According to above-mentioned design of the present utility model, described left and right sleeve is the major part of this fixture, and be the sleeve of two long 150mm, the eccentric 1mm of inside and outside circle respectively, can shape rear incision is two pieces simultaneously, as the main location of workpiece.
Advantage of the present utility model and benefit are: the use of eccentric special fixture improves production efficiency effectively, ensure that product quality, the production of suitable especially large quantities of products part.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is horizontal section schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As shown in Figure 1 be that the utility model provides a kind of fixture, it is made up of right baffle-plate 1, left sleeve 2, housing screw 3, connecting plate 4, right sleeve 5, rhombus pin 6, screw 7, right baffle plate 8, taper bolt 9; Described left sleeve 2 one end is connected with described right baffle-plate 1, and the other end is connected with housing screw 3; Described connecting plate 4 is a rectangle iron block, and its one end is connected with right baffle-plate 1, and one end is connected with right baffle plate 8 in addition; Described rhombus pin 6 embeds in 2,3, left and right cover respectively; Described taper bolt 9 embeds in left and right baffle plate 1,8 respectively; Described left and right sleeve is the major part of this fixture, and be the sleeve of two long 150mm, the eccentric 1mm of inside and outside circle respectively, can shape rear incision is two pieces simultaneously, as the main locating surface of workpiece.When designing sleeve, if one end of left and right sleeve is processed long 30mm, with inner eccentric holes 1mm cylindrical, the concentric periphery of cylindrical of separately reprocessing out a segment length 10mm on right sleeve, growing with 30mm.During use, the cylindrical of left sleeve 30mm length is used as grinding machine clamping, and because workpiece is comparatively large, the cylindrical of right sleeve 30mm length is as the benchmark taking centre frame, and the cylindrical of 10mm length is then as fixture clamping centering benchmark on lathe.In use, the bias of left and right two sleeves is consistent in position is the key of dealing with problems.When designing, the left and right end face of condition-workpiece of workpiece itself is utilized to have 6 screws respectively, the corresponding screw of left and right for workpiece end face on same position is made two fabrication holes, when doing this hole, technique to ensure and the position of keyway on cylindrical and angle requirement (because processing on same workpiece, manufacturing and being easier to).Fixture right baffle-plate 1, right baffle plate 8 are contained in the end face of left and right sleeve respectively, limit the axially-movable of workpiece; Two baffle plates are loaded on two rhombus pins 6, make it be in the position in just in time insertion process hole, in order to limit the rotational freedom of work.During assembling, for preventing loosening displacement, after the position correction of left and right baffle plate and left and right sleeve, except tightening up with screw 7, and stamping two taper bolts 9, guaranteeing that location is reliable.Like this, the position accuracy demand of fixture can be ensured.After workpiece is reliably located, the annulus of left and right sleeve is opened a dry screw, uses holding screw workpiece pressing, make workpiece become as a whole with fixture.When turning and grinding, the moment of torsion on a sleeve will be delivered on another sleeve, in order to safe and reliable, adds detachable connecting plate 4 between two sleeves, makes two sleeve connection integral.
Claims (2)
