Description
Technical field
The utility model relates to field of fixtures more particularly to a kind of for fixing the spring chuck of commutator lower end surface.
Background technique
Currently, the spring chuck for being mounted on machining apparatus such as numerically controlled lathe, function is to clamp workpiece.It is existing
The spring chuck of use is surrounded by muti-piece metal to be made, when in use, metal is integrally drawn backward, the taper on collet is locked
Tightly to clamp workpiece.For example, Chinese patent literature CN106862601A discloses a kind of lathe inner-supporting type spring collet, packet
Include: blade in the outer tabletting of locating rod, muti-piece and muti-piece, the outer tabletting of muti-piece are intervally arranged with blade in muti-piece, muti-piece external pressure
On piece is equipped with external pressure bar portion, external pressure forced section and external pressure head, and muti-piece inner support on piece is equipped with inner support bar portion, inner support stress
Portion, inner support head and clamping part, multiple external pressure bar portions and multiple inner support bar portions are enclosed connection rod structure, multiple external pressures by
Power portion and multiple inner support forced sections are enclosed inclination stress surface, and multiple external pressure heads and multiple inner support heads are enclosed tip
Structure, multiple clamping parts are enclosed the raised platform of clamping workpiece to be processed, and the inner wall of workpiece to be processed is engaged with raised platform.
When pulling locating rod to lathe direction, opening of the stress surface on lathe is extruded, and external pressure forced section is squeezed in extrusion process
Pressure is biased inwardly, and causes inner support head and clamping part inclined outward, and the outer diameter of clamping part becomes larger, and workpiece to be processed is clamped in portion
Power is fixedly clamped.When this structure is tightened, there is a gradient with the contact surface of workpiece, using made of simple metal structure
Collet is easy to crush during tightening to by comparing clamping face that sharp shape forms and non-metal workpiece.
In order to solve the above-mentioned technical problem, Chinese patent literature CN107008931A discloses a kind of Split type flexible folder

Cross multiple screw axial connections.By the way that collet and elastic collet body are set to split type structure, collet is available after separating
Nonmetallic materials or the manufacture of other metal materials, and the inner hole of collet may be designed to shape similar with work piece outer circle, this
Sample, which can not only be clamped, forms the part and non-metal workpiece in clamping face by comparing sharp shape, and is not easy to press from both sides part
Wound.But the commutator relatively high for requirement on machining accuracy, usually the radially outer periphery face of commutator lower end surface is carried out
It is fixed, and there are burr on commutator radially outer periphery face, fixture is fixed after commutator, causes commutator in process
In, burr is easy to damage the clamping face of fixture, so that the fixed precision of fixture declines, causes the processing dimension of commutator unstable
It is fixed.If directly above-mentioned Split type flexible collet is applied in above-mentioned lathe inner-supporting type spring connector, although can exchange
To device play the role of it is certain grip, while avoiding the damage of burr, but the split type collet needs elastic collet body
With the cooperation of collet, i.e. the two applies inside extruding force to commutator simultaneously and could be clamped, and this extruding force exists
Certain uncertainty, if collet occurs to rotate a little inside elastic collet body, position of the commutator in collet also can be with
Change, and then influence the stability of commutator processing dimension.
