Description
Technical field
This utility model be related to clamp fixture field and in particular to thin wall casing processing when clamping frock clamp.
Background technology
Cooling jacket is a bottle strength member for embryo injection mould, and its material is aluminium alloy, has good, the yielding spy of plasticity
Point.Cooling jacket wants clamping position when processing outer surface, and the usually outer rim in cooling jacket two-port arranges step cutting pattern,
Then two canular fixtures are socketed on the step cutting pattern of two-port respectively, opposite firmly clamping, cooling jacket holds very much
Easily occur bending and deformation, the thin wall casing that especially wall thickness in cooling jacket is relatively thin, pipe range is longer is easier flexural deformation.In
State's patent CN105729346, date of publication on July 6th, 2016, a kind of patent name Central Symmetric pipe positioner, public
A kind of inclusion bottom positioning mould, top pressure die, left vee-block, the pipe positioner of right vee-block, top compression module are opened
Directly over the locating module of bottom, left vee-block and right vee-block are symmetrically set in the locating module left and right sides, left and right V-arrangement
Screw slide block is revolved in being respectively arranged below with of block, and a two-way leading screw passes through two rotation screw slide blocks, and this pipe positioner is from circle
Four sides of pipe are clamped, and can provide preferable clamping and positioning effect to general pipe, but not be suitable for thin wall casing, because
Extruding or depressed deformation may be brought it about for a direction is somewhat firmly excessive.
Utility model content
It is susceptible to the problem on deformation such as bending, extruding, depression, mesh of the present utility model during for thin wall casing clamping position
Be provide one kind can effectively clamp thin wall casing, it is to avoid produce bending, extruding, depression etc. problem on deformation, in order to thin
Wall covers the clamp structure of Tube processing line.
This utility model provides following technical scheme：
A kind of thin wall casing clamp structure, including the clamping axle sleeve being adapted to thin wall casing internal diameter, and the core of a rigidity
Axle, the side of described mandrel is provided with socket section, and the opposite side of described mandrel is provided with canned paragraph, described socket section and described canned paragraph
Between be provided with socket frustum, the diameter of described socket frustum is gradually reduced along canned paragraph to being socketed section, described clamping axle sleeve and institute
State socket section socket, described clamping axle sleeve is provided with, near the port of described canned paragraph side, first being adapted to described socket frustum

Produce relatively fixed position relation between axle sleeve it is impossible to relatively rotate with clamping axle sleeve, realize the clamping of thin wall casing.
So clamp structure of the present utility model is set in the inside of thin wall casing, by the inner surface generation radial direction side to thin wall casing
To expansive force, so that thin wall casing is clamped, clamping axle sleeve radial direction distending deformation can make thin wall casing avoid produce depression, squeeze
Compressive strain, the mandrel of the rigidity in clamping axle sleeve makes thin wall casing avoid occuring bending and deformation.In addition thin wall casing itself also because
Larger expansive force can be born without the tear deformation that distending occurs.The outer surface that thin wall casing so can be facilitated is processed, real
Now produce, in addition this utility model is equally applicable to the clamping position of the thicker sleeve pipe of wall thickness.
As a kind of improvement of the present utility model, the stress that described clamping axle sleeve is provided with positioned at described cutting seam end subtracts
Weak hole.The stress that cutting seam end is subject to so can be reduced, it is to avoid when distending deformation is larger, the end of cutting seam is torn
Open.
As a kind of improvement of the present utility model, the outer rim near described binding nut side for the described clamping cone sleeve is provided with outer
Side is the hand-held projection on the face of cylinder, and described hand-held raised lateral surface is provided with grid anti-slip veins.Hand-held projection can conveniently be pressed from both sides
The installation of tight tapered sleeve, grid anti-slip veins then can increase the frictional force of the lateral surface of hand-held projection, conveniently holds hand-held projection.
As a kind of improvement of the present utility model, described socket section is provided with center calmly away from the end of described canned paragraph side
Position hole.So cutting can be increased just in turnery processing with the center positioning hole of the top top jail socket section of tail stock
Property, the axiality that ensures between mandrel and sleeve pipe.
As a kind of improvement of the present utility model, the internal diameter of described clamping axle sleeve is more than the external diameter of described socket section, makes institute
State clamping axle sleeve to be slidably matched with described socket section.So it is easy to clamp axle sleeve along socket section movement.
As a kind of improvement of the present utility model, it is provided between described binding nut and described clamping cone sleeve and described socket
The equal power pad of section socket, described equal power pad is uniformly distributed 4 fastening screws, described folder near the one side of described clamping cone sleeve
The end face of tight tapered sleeve is provided with the detent of 4 adaptations.All power pads can make nut uniform to the active force of clamping cone sleeve
Distribution, prevents clamping cone sleeve from producing the moment of torsion of rotation, and all the location structure between power pad and clamping cone sleeve is able to ensure that
In rundown process, equal power pad will not be with nut rotation.
The beneficial effects of the utility model are as follows：
This utility model pass through inside thin wall casing setting can radial direction distending clamping axle sleeve realize to thin wall casing
Clamping position, it is to avoid thin wall casing occur depression, extruding, flexural deformation the problems such as, be easy to the processing of thin wall casing, and
