Description
Technical field
It the utility model is related to a kind of TO gauges sensor base.
Background technology
The most integrated pedestals of existing pressure sensor pedestal, all internal hole millings of its structural requirement, Er Qiejia
Work precision requires higher, and processing technology is excessively complicated, thus causes machining process cost too high.Simultaneously because pedestal belongs to one
Body structure, must be longer according to pile line operation, production cycle in assembling process is produced.
The content of the invention
The purpose of this utility model is to provide a kind of TO gauges sensor base, is by base sleeve and base body two
Divide and form, parts processing, two-part structure is all very simple, thus processing technology is simple, saves machining process cost.
To achieve the above object, the utility model is realized using following technical scheme：
A kind of TO gauges sensor base, including base body, base sleeve, acupuncture needle, gauge pressure pipe, base body are welded and fixed
In base sleeve, acupuncture needle is fixed through base body and by glass insulator, and gauge pressure pipe is fixed on base also by glass insulator
It is through hole inside gauge pressure pipe on pedestal.
Seal groove is provided with the outside of the base sleeve, the lower surface of base sleeve inner chamber is provided with the tip projection of annular,
The projection is welded and fixed with base body, and the upper surface of base sleeve is additionally provided with silicon oil infilling chamber.
The base body is circular sheet-like structures, and the mounting hole of acupuncture needle and gauge pressure pipe is provided with base body.
Compared with prior art, the beneficial effects of the utility model are：
The utility model provides a kind of TO gauges sensor base, for assembling gauge sensor, the base
Baroque integrated base is divided into two parts simple in construction by seat, and carries out machining process respectively, then passes through storage
It can be welded and fixed.Two-part structure is all very simple, thus processing technology is simple, saves machining process cost, and sensing
Man-hour and cost of labor in device production process.
Base sleeve is simple in construction, and inner chamber does not need excessive hole milling to finish, and simplifies machining process technique, reduces system
Make cost.
Base body structure is more simple, and its overall structure is sheet, individually carries out hole milling processing, and mechanical processing technique is more simple
It is single, it can effectively reduce cost of manufacture.
In addition, base body can be installed according to the supporting selection of the model of pressure sensor pressure chip, and base sleeve can be with
Using unified standard model, the processing and assembling for making sensor are all standardized, also saved while processing cost is reduced
Man-hour and cost of labor during sensor production.

Embodiment
The utility model is described in detail with reference to Figure of description, it should be noted that of the present utility model
Implementation is not limited to following embodiment.
As Figure 1-Figure 5, a kind of TO gauges sensor base, including base body 2, base sleeve 3, acupuncture needle 4, gauge pressure
Pipe 5, base body 2 are weldingly fixed in base sleeve 3, and acupuncture needle 4 is through base body 2 and is fixed by glass insulator 6, gauge pressure pipe 5
It is fixed on also by glass insulator 6 on base body 2, the inside of gauge pressure pipe 5 is through hole.
Seal groove is provided with the outside of the base sleeve 3, the lower surface of the inner chamber of base sleeve 3 is provided with the sophisticated convex of annular
Rise, the projection is welded and fixed with base body 2, and the upper surface of base sleeve 3 is additionally provided with silicon oil infilling chamber 1.
The base body 2 is circular sheet-like structures, and the mounting hole of acupuncture needle 4 and gauge pressure pipe 5 is provided with base body 2.
O-ring seal is placed in seal groove, realizes sealing during pressure measurement installation.The cavity of the lower end of base body 2 is compensation
Plate mounting groove, the circuit board of temperature-compensating is carried out to pressure chip for laying.
A kind of TO gauges sensor base of the utility model, installs gauge pressure pipe 5 on base body 2, and assembling pressure passes
During sensor, pressure chip is arranged on the upper end of the latus rectum of gauge pressure pipe 5, and gauge pressure pipe 5 is used for the back side of pressure chip and ambient atmosphere
Communicate, therefore it is actual pressure relative to the pressure under atmospheric environment to use the pressure measured by the pressure sensor that this pedestal assembles
Power, i.e., it is offset output in atmospheric pressure environment lower sensor.
A kind of TO gauges sensor base of the utility model, base body 2 welds with the closing of base sleeve 3, in base body 2
The position of upper installation pressure chip is mounted with the gauge pressure pipe 5 for leading to air.Metal Substrate pedestal 2 uses split with Metal Substrate cover for seat 3
Change structure, carry out machining process respectively, be then welded and fixed, simplify mach processing technology, reduce production cost.
