Description

Adjustable in length formula pneumatic jack connects post
Technical field
The utility model belongs to Auto body panel die design and manufactures parts technical field, particularly relates to a kind of adjustable in length formula pneumatic jack and connects post.
Background technology
Utilize machine tool air cushion as power source more and more widely in existing drawing die and postorder mould, so not only can provide stable pressure but also the expense in a large sum of volumn of purchase external pressure source can be saved.But because foundry goods cannot directly be connected with air cushion by mould structure restriction, so use pneumatic jack connects the instrument that post transmits as pressure usually.
In prior art, pneumatic jack connects column length and fixes, unadjustable, once buying just cannot be changed, the scope of application is little and cannot tackle emergency case, as shown in Figure 1.The blank mostly column production flow process is stock's different length is connect concerning existing pneumatic jack supplier, and intercepts processing according to the physical length of client feedback temporarily, not only waste material but also extend the delivery cycle, cannot directly get stock ready as standard component and immediately deliver.For mould factory, there is many reasons can cause becoming the stroke change of foundry goods, as bus is different from the lathe of debugging line, because binder change of circumstance needs the situations such as Iterim Change foundry goods stroke.Need the suitable pneumatic jack of extra purchase length to connect post by normal solution, will cause so unnecessary connecing post, cannot sundry item is applicable to and cause waste.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of adjustable in length formula pneumatic jack and connects post, it is adjustable for being separated that pneumatic jack connects post, originally semi-finished product are turned into finished product standard component, and so not only can be mass-produced stock but also can meet the multiple emergency case of mould factory.
To achieve these goals, the utility model adopts following technical scheme:
A kind of adjustable in length formula pneumatic jack connects post, it is characterized in that comprising punch plug-in unit, die plug-in unit, the top that described punch plug-in unit comprises joint pin and is fixedly connected with joint pin, described joint pin is provided with the first sawtooth be equally spaced, described die plug-in unit comprises die body and is opened in the groove in die body, be provided with the second sawtooth matched with described first sawtooth in described groove, bottom described die body, have screwed hole;
Also comprise hold-down screw, the screw thread of described hold-down screw and diameter and described screwed hole match.
The length of described joint pin is identical with the degree of depth of described groove.
Each tooth pitch of described first sawtooth is 5mm.
Each tooth pitch of described second sawtooth is 5mm.
The beneficial effects of the utility model are: pneumatic jack connects post and is made up of separable three parts, the length making pneumatic jack connect post can adjust according to actual conditions, the model of hold-down screw can be selected, in addition the cooperation of the first sawtooth and the second sawtooth, can make punch plug-in unit, die plug-in unit is fastenedly connected; The tooth pitch of the first sawtooth and the second sawtooth is fixing, the convenient distance regulating each pneumatic jack to connect post to contact with lathe, makes each pneumatic jack connect the length of post identical, and then make each pneumatic jack connect post uniform force, not easily be bent, extend service life, and processing effect is good; Hold-down screw can play firm and supporting role to the connection of punch plug-in unit, die plug-in unit, also makes each pneumatic jack connect rod structure and stablizes, not easily sideslip and bending.The pneumatic jack that script length is fixing is connect post and becomes adjustable length nodal pattern by the utility model, semi-finished product are originally turned into finished product standard component, and so both can be mass-produced stock, can meet again the multiple emergency case of mould factory, reduce production cost, save material.

Detailed description of the invention
Below in conjunction with accompanying drawing, a kind of detailed description of the invention of the present utility model is explained.
As shown in Figure 1, Figure 2, Figure 3 shows, the utility model provides a kind of adjustable in length formula pneumatic jack to connect post, comprise punch plug-in unit 1, die plug-in unit 2, the top 5 that described punch plug-in unit 1 comprises joint pin 4 and is fixedly connected with joint pin 4, described joint pin 4 is provided with the first sawtooth 8 be equally spaced, the groove 7 that described die plug-in unit 2 comprises die body 6 and is opened in die body 6, be provided with the second sawtooth 9 matched with described first sawtooth 8 in described groove 7, bottom described die body 6, have screwed hole (not marking in figure);
Also comprise hold-down screw 3, the screw thread of described hold-down screw 3 and diameter and described screwed hole match.
The length of described joint pin 4 is identical with the degree of depth of described groove 7.
Embodiment 1: as shown in Figure 4, the adjustable in length formula pneumatic jack of the present embodiment connects post and comprises punch plug-in unit 1, die plug-in unit 2, hold-down screw 3, the top 5 that described punch plug-in unit 1 comprises joint pin 4 and is fixedly connected with joint pin 4, described joint pin 4 is provided with the first sawtooth 8 be equally spaced, the groove 7 that described die plug-in unit 2 comprises die body 6 and is opened in die body 6, be provided with the second sawtooth 9 matched with described first sawtooth 8 in described groove 7, bottom described die body 6, have screwed hole (not marking in figure), the tooth pitch of described first sawtooth 8 or the second sawtooth 9 is 5mm, pneumatic jack is connect post and is adjusted to equal length by such convenience, hold-down screw 3 is screwed in die body 6 by screwed hole outside die plug-in unit 2, the length of hold-down screw 3 can be selected according to model, to adapt to adjustment and the application that different length pneumatic jack connects post, then punch plug-in unit 1 is screwed in die plug-in unit 2, by the first sawtooth 8 of cooperatively interacting and the second sawtooth 9, joint pin 4 is tightened, and then hold-down screw 3 is compressed, reach pneumatic jack and connect the adjustable effect of column length, and due to the existence of hold-down screw 3, total is firm in support process, not sideslip.
