Description
Technical field
A kind of the invention belongs to Auto body panel die design manufacture parts technical field, more particularly to adjustable in length formula gas
Apical grafting post.
Background technology
So can both provide more and more widely by the use of machine tool air cushion as power source in existing drawing die and postorder mould
Stable pressure can save the expense in writing buying extra pressure source again.But as mould structure restriction cannot directly by foundry goods
It is connected with air cushion, so pneumatic jack is usually used connects post as the instrument of pressure transmission.
In prior art, pneumatic jack connects column length and fixes, unadjustable, once buying just cannot be changed, the scope of application is little and nothing
Method tackles emergency case, as shown in Figure 1.It is stock's different length mostly that for supplier, existing pneumatic jack connects column production flow process
Blank, and processing is intercepted temporarily according to the physical length of client feedback, not only waste of materials but also has extended the delivery cycle, it is impossible to as
Standard component is equally directly got stock ready and is delivered immediately.For mould factory, there are many reasons cause the stroke of change foundry goods
Change, such as bus is different from the lathe of debugging line, because situations such as binder change of circumstance needs Iterim Change foundry goods stroke.Press
Normal solution needs the suitable pneumatic jack of extra purchase length to connect post, so may result in and unnecessary connects post, it is impossible to is suitable for
Cause to waste in sundry item.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, it is an object of the invention to provide a kind of adjustable in length formula pneumatic jack connects post, gas
Apical grafting post is adjustable for separating, and the semi-finished product of script are turned into finished product standard component, so not only can be mass-produced stock but also
Various emergency cases of mould factory can be met.
To achieve these goals, the present invention is adopted the following technical scheme that：
A kind of adjustable in length formula pneumatic jack connects post, it is characterised in that including punch plug-in unit, die plug-in unit, the punch plug-in unit bag
The top for including connecting pole and being fixedly connected with connecting pole, the connecting pole are provided with the first sawtooth being equally spaced, the die
Plug-in unit includes die body and the groove being opened in die body, is provided with second be engaged with first sawtooth in the groove
Sawtooth, the die body bottom are provided with screwed hole；
Also include fixing screws, screw thread and diameter and the screwed hole of the fixing screws match.
The length of the connecting pole is identical with the depth of the groove.
Each tooth pitch of first sawtooth is 5mm.
Each tooth pitch of second sawtooth is 5mm.
Beneficial effects of the present invention are：Pneumatic jack connects post and is made up of separable three part so that pneumatic jack connects the length of post can basis
Practical situation is adjusted, and the model of fixing screws can be selected, in addition the cooperation of the first sawtooth and the second sawtooth, can
So that punch plug-in unit, die plug-in unit are fastenedly connected；The tooth pitch of the first sawtooth and the second sawtooth is fixed, conveniently adjusts each
Pneumatic jack connects the distance that post is contacted with lathe so that the length that each pneumatic jack connects post is identical, and then causes each pneumatic jack to connect post stress
Uniformly, it is difficult to be bent, extends service life, and processing effect is good；Fixing screws can be inserted to punch plug-in unit, die
Firm and supporting role is played in the connection of part, is also made each pneumatic jack connect rod structure and is stablized, is difficult sideslip and bending.The present invention will
The pneumatic jack that script length is fixed connects post and becomes adjustable length nodal pattern, the semi-finished product of script is turned into finished product standard component, so both
Can be mass-produced stock, can meet various emergency cases of mould factory again, reduce production cost, saved material.

Specific embodiment
Below in conjunction with the accompanying drawings a kind of specific embodiment of the present invention is explained.
As shown in Figure 1, Figure 2, Figure 3 shows, the present invention provides a kind of adjustable in length formula pneumatic jack and connects post, including punch plug-in unit 1,
Die plug-in unit 2, the top 5 that the punch plug-in unit 1 is included connecting pole 4 and is fixedly connected with connecting pole 4, the connecting pole 4
The first sawtooth 8 being equally spaced is provided with, the die plug-in unit 2 includes die body 6 and the groove 7 being opened in die body 6,
The second sawtooth 9 being engaged with first sawtooth 8 is provided with the groove 7, and 6 bottom of the die body is provided with screwed hole (figure
In do not mark)；
Also include fixing screws 3, screw thread and diameter and the screwed hole of the fixing screws 3 match.
The length of the connecting pole 4 is identical with the depth of the groove 7.
Embodiment 1：As shown in figure 4, the adjustable in length formula pneumatic jack of the present embodiment connects post includes punch plug-in unit 1, die plug-in unit
