Description
Technical field
The utility model relates to part processing clamp field more particularly to a kind of collet housing and with the collet housing
Inner propping collet.
Background technique
Inner propping collet refers in insertion hole in piece part, and can spreading realize the fixed fixture of part thus tensioner part.
Inner propping collet realizes that the component of spreading is housing, and existing housing as shown in figure 4, put on for being provided with and being extended internally by one end outside
One deformation slot and the second deformation slot to be extended internally by the other end, the first deformation slot and the second deformation slot are arranged alternately.Inner support folder
Housing is supportted outside the other component of head, housing deforms slot and opens, and outer diameter increases, tensioner workpiece.The housing of the structure and have that this is outer
The shortcomings that inner propping collet of set are as follows: housing realizes a wide range of expansion by deformation slot, but deforms slot and be not penetrated housing, does not open deformation
The coat part deformation of slot is limited, and collet housing expands unevenly in the axial direction, influences chucking power and clamp precision；And
Also cause housing to be concentrated in the position stress of deformation slot root, be easy cracking.
Utility model content
Technical problem to be solved by the utility model is: providing a kind of uniform collet housing of axial expansion.
In order to solve the above problem the technical solution adopted is that: two end faces of collet housing are respectively first end face and second
End face, collet outer jacket surface are supporting surface, have in collet housing and are extended internally by first end face and coaxial with supporting surface
Conical bore, collet housing divide equally at least three outer jacket members of formation along axial, and adjacent outer jacket member passes through rubber parts and connects.
Further, rubber parts shape is L shape, rubber parts is that simultaneously close support axially is arranged along collet housing on one side
The horizontal edge in face, the another side of rubber parts are along second end face setting and close to the longitudinal edge of second end face.
Further, being provided with inward flange between conical bore and second end face in collet housing.
Another technical problem to be solved in the utility model is: providing a kind of uniform inner propping collet of axial expansion.
In order to solve the above problem the technical solution adopted is that: inner propping collet includes collet housing, mandrel and pull rod；Outside collet
Two end faces of set are respectively first end face and second end face, and collet outer jacket surface is supporting surface, have in collet housing by
First end face extends internally and the conical bore coaxial with supporting surface, and collet housing divides equally at least three housing groups of formation along axial
Part, adjacent outer jacket member are connected by rubber parts；Pull rod includes pull rod main body and the platen that connect with pull rod main body, pull rod main body
Across collet housing；There is the circular conical surface being adapted to conical bore, core sleeve is in pull rod main body on mandrel；Inner propping collet uses
When, second end face is resisted against on platen, and circular conical surface is resisted against on conical bore.
Further, rubber parts shape is L shape, rubber parts is that simultaneously close support axially is arranged along collet housing on one side
The horizontal edge in face, the another side of rubber parts are along second end face setting and close to the longitudinal edge of second end face.
Further, being provided with inward flange between conical bore and second end face in collet housing, have in pull rod main body
There is the outward flange that can be resisted against on inward flange.
The beneficial effects of the utility model are: 1, collet housing is along axial respectively at least three outer jacket members of formation, it is adjacent
Outer jacket member is connected by rubber parts, and since rubber parts has elasticity, collet housing can be realized expansion.
2, in entire collet housing axial direction, outer jacket member is only connected by rubber parts, is had no other structures and is limited its deformation,
Therefore collet housing axis is upwardly-deformed uniform, and chucking power is uniform, and clamp precision is high.
3, there is no stress concentration portion, be conducive to improve the inner propping collet service life.
