Abstract
The utility model discloses a kind of chuck of fixture, including matrix, described matrix is provided with insert, insert is provided with the top surface that bushing, bushing top surface is higher than insert, and bushing top end face is provided with leakage powder tank, lumen pore is provided with matrix, ejector pin mechanism is provided with lumen pore, ejector pin mechanism includes regulating block, spring and the thimble being sequentially arranged, and thimble is exposed to insert surface through insert.The utility model set insert and it is bushing between formed ladder section, reduce the contact area with blank, and then reduce abrasion, increase service life, can reduce and change fixture number, save cost, it ensure that product quality simultaneously, production efficiency is improved, and sets leakage powder tank to discharge powder, avoids powder accumulation from influenceing fixture work.
Description
Technical field
The utility model belongs to field of fixtures, more particularly to a kind of chuck of fixture.
Background technology
At present, when powder metallurgy product is processed, fixture need to be used by the spacing fixation of product.A blank is often processed, is pressed from both sides
Tool carries out clamping primary production by automatics, and so circulation is worked continuously.The chuck of blank and fixture in clamping process
Between rubs mutually be present, when produced in large volumes, blank frequently rubs with clamping fixture head, and clamping fixture head easily wears.And press from both sides
Clamping precision can be influenceed after tool chuck abrasion, causes blank forming error to increase, causes bad part, this just needs more to renew fixture folder
Head could continue to produce, and the increase and production capacity for causing fixture cost are reduced.
Utility model content
For overcome the deficiencies in the prior art and the problem of exist, the utility model provides a kind of chuck of fixture, uses the longevity
Life is high, improves the machining accuracy of blank.
The utility model is achieved through the following technical solutions：
A kind of chuck of fixture, including matrix, described matrix are provided with insert, and insert is provided with bushing, bushing top surface
Higher than the top surface of insert, bushing top end face is provided with leakage powder tank, and lumen pore is provided with matrix, ejector pin mechanism, thimble are provided with lumen pore
Mechanism includes regulating block, spring and the thimble being sequentially arranged, and thimble is exposed to insert surface through insert.
It is described leakage powder tank be provided with it is multiple, by bushing middle part towards surrounding emission-type arrange.
The insert includes basal part and top, and cascaded surface is provided between basal part and top, and basal part is flush-mounted in matrix
On, top is placed in bushing.
The cross section of the insert is cubic shape, and the end face center of insert is provided with circular protrusions.
It is described it is bushing be square internally and round externally structure.
The insert and bushing making material are wolfram steel.
The regulating block is provided with external screw teeth, and lumen pore bottom is provided with internal screw thread, and regulating block is tightened against lumen pore bottom.
Insert that the utility model is set and it is bushing between form ladder section, reduce with the contact area of blank, and then
Abrasion is reduced, increases service life, can reduce and change fixture number, save cost, while ensure that product quality, improves life
Efficiency is produced, and sets leakage powder tank to discharge powder, avoids powder accumulation from influenceing fixture work.

Embodiment
For the ease of the understanding of those skilled in the art, the utility model is made below in conjunction with the drawings and specific embodiments into
One step is described in detail.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of chuck of fixture, including matrix 1, matrix 1 are provided with insert 2, insert
2 are higher than the top surface of insert 2 provided with bushing 3, bushing 3 top surface, therefore ladder section is formed between insert 2 and bushing 3.Insert 2
Including basal part 21 and top 22, cascaded surface is provided between basal part 21 and top 22, basal part 21 is flush-mounted on matrix 1, on
Portion 22 is placed in bushing 3.The cross section of insert 2 is cubic shape, and the end face center of insert 2 is provided with circular protrusions 23.Bushing 3 are
Square internally and round externally structure, bushing 3 inwall match with insert 2.Insert 2 and bushing 3 making material are wolfram steel, wear-resistance and anti-corrosion.
Bushing 3 top end face is provided with leakage powder tank 31, and powder can discharge from leakage powder tank 31.For row's powder of lifting leakage powder tank 31
Ability, leakage powder tank 31 be provided with it is multiple, by bushing 3 middle part towards surrounding emission-type arrange.
Is provided with lumen pore in matrix 1, is provided with ejector pin mechanism 4 in lumen pore, ejector pin mechanism 4 including be sequentially arranged regulating block 41,
Spring 42 and thimble 43, thimble 43 are exposed to the surface of insert 2 through insert 2.Regulating block 41 is provided with external screw teeth, and lumen pore bottom is set
There is internal screw thread, regulating block 41 is tightened against lumen pore bottom, and rotation regulating block 41 is the pretightning force of adjustable springs 42.
Above-described embodiment is preferable implementation of the present utility model, is not to restriction of the present utility model, not
On the premise of departing from inventive concept of the present utility model, it is any it is obvious replace the scope of protection of the utility model it
It is interior.
