Description
【Technical field】
The utility model belongs to fine positioning technical field, and in particular to a kind of constant pressure holding meanss.
【Background technology】
In mould structure, mold generally comprises two parts of dynamic model and cover half (or punch-pin and cavity plate), and the two can divide can
It closes；, it is necessary to ensure the precision of mold with 2~4 fine positionings when dynamic model coordinates with cover half.Meanwhile fine positioning can be divided into again
Fine positioning and lower fine positioning, the two fit form are tapered nest close-fitting.Traditional handicraft is by upper fine positioning and lower essence with pressure
Positioning compression.This technique because pressure size can not monitor in real time, cause to press the fine positioning difference in height of attached same mold compared with
Greatly, dynamic model and cover half poor fit, cause product yield to reduce.
Therefore, the utility model be based on more than deficiency and generate.
【Utility model content】
The technical problem to be solved by the present invention is to provide a kind of constant pressure holding meanss, which is directed to mold
Middle fine positioning difference in height inconsistence problems, control pressure, it is ensured that each fine positioning in nesting in one set of die
Pressure during close-fitting is consistent.
In order to solve the above technical problems, the utility model employs following technical proposals：A kind of constant pressure holding meanss,
It is characterised in that it includes：Frame body is provided with to place the localization tool of fine positioning on the frame body, be set on the frame body
There is the briquetting that can be moved up and down and be squeezed when moving down fine positioning, be additionally provided with to drive briquetting on the frame body
The cylinder of lower movement is provided with pressure sensor below the localization tool.
A kind of constant pressure holding meanss as described above, which is characterized in that be provided with to put on the localization tool
Put the groove of fine positioning.
A kind of constant pressure holding meanss as described above, which is characterized in that be provided on the frame body and exist for briquetting
Frame body is in the guide rail of slip.
A kind of constant pressure holding meanss as described above, which is characterized in that be additionally provided with to adjust on the frame body
The pressure regulator valve of cylinder pressure.
Compared with prior art, a kind of constant pressure holding meanss of the utility model, have reached following effect：
1st, the utility model controls pressure for multiple fine positioning difference in height inconsistence problems in mold, can be with
Ensure that the pressure in nested close-fitting of each fine positioning in one set of die is consistent, it is highly consistent so as to ensure, ensure after compressing
The difference in height of each fine positioning, so as to promote the precision that dynamic model and cover half coordinate each other, promotes product yield within 3 μm.
2nd, the utility model is simple in structure, small, it is easy to operate, debugging take it is less, flexible, it is at low cost.
【Description of the drawings】
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings, wherein：
Fig. 1 is the structure chart of the utility model；
Description of the drawings：1st, frame body；2nd, fine positioning；3rd, localization tool；31st, groove；4th, briquetting；5th, cylinder；6th, pressure sensing
Device；7th, guide rail；8th, pressure regulator valve.
【Specific embodiment】
It elaborates below in conjunction with the accompanying drawings to the embodiment of the utility model.
As shown in Figure 1, a kind of constant pressure holding meanss, including：Frame body 1 is provided with to place essence on the frame body 1
2 localization tool 3 is positioned, the briquetting that can be moved up and down and be squeezed when moving down fine positioning 2 is provided on the frame body 1
4, the cylinder that briquetting 4 is driven to move up and down 5 is additionally provided on the frame body 1, and the lower section of the localization tool 3 is provided with pressure
Force snesor 6.Attached fine positioning is pressed using cylinder, after reaching certain pressure, fine positioning stops cylinder the reaction force of cylinder
It pushes.Pressure value size is recorded by pressure sensor at this time, it is ensured that and each cylinder presses the power of attached fine positioning consistent,
Finally by the size for adjusting cylinder air pressure, the steady pressure in different range can be obtained, for meeting the need of various occasions
It asks.
As shown in Figure 1, it in the present embodiment, is provided with to place the groove 31 of fine positioning 2 on the localization tool 3.
As shown in Figure 1, in the present embodiment, be provided on the frame body 1 for briquetting 4 frame body 1 slip guide rail
7。
As shown in Figure 1, it in the present embodiment, is additionally provided with to adjust the pressure regulator valve 8 of 5 pressure of cylinder on the frame body 1.
By adjusting the pressure size of pressure regulator valve 8, the pressure value for pressing attached fine positioning 2 can be controlled.
Specific implementation step：
A, fine positioning 2 is first placed in localization tool 3.Meanwhile pressure sensor 6 is put into the lower end of localization tool 3；
B, during controlling the pushing of cylinder 5, briquetting 4 pushes therewith, and finally pressure is attached to 2 surface of fine positioning；
C, the pressure by briquetting 4 is attached, and by upper fine positioning close-fitting nested with lower fine positioning, while pressure value passes through pressure sensing
Device 6 shows that the atmospheric pressure value of cylinder 5 also can directly be read by pressure regulator valve 8；
D, keep air pressure it is motionless, other fine positionings 2 of same mold are also carried out pressing it is attached, at this time pressure value with for the first time
The pressure size for pressing attached fine positioning 2 is completely the same, it is ensured that 2 difference in height of all fine positionings in same mold is in 3 μm；
E, in this arrangement, by adjusting the pressure size of pressure regulator valve 8, the pressure value for pressing attached fine positioning 2 can be controlled.
The size of obtained pressure value and air pressure size direct proportionality.
F, proper air pressure value size is selected as needed, it is ensured that cylinder 5 is to every 2 consistent pressure of fine positioning.
It is pressed by this constant pressure attached, it is ensured that 2 difference in height of fine positioning after pressure is attached is constant.
