Technical field
The invention belongs to mechanical field, and in particular to a kind of pressure sensor.
Background technology
At present, pressure sensor is typically welded with entering pressure head and welding together using electron-beam welder.
Wherein, the structure of pressure sensor is usually such：With enter pressure head welding side be a plane, put down
There are some pins and an oil-filled hole on face, some pin bores for fixing pin for filling glass adopt cylinder
The form in shape hole.When pressure head is entered and pressure sensor is coordinated, inconvenience will enter pressure head to be carried out with sensor
Tighten cooperation；When pressure head and pressure sensor is entered during electron beam weldering, there is pin in this structure
The problem of protection inconvenience；When pressure head and pressure sensor is entered in working environment, this structure is present draws
(in the presence of high pressure and dither, the micro- molten glass of filling may be with sensing for the hidden danger that pin may come off
No longer tightly adhesion, may come off with pin between device base).These problems are eventually affected into pressure head
Working effect, is likely to result in high risks.
The content of the invention
It is an object of the invention to provide a kind of pressure sensor, solves pin and hold caducous hidden danger, improve
Operating efficiency.
For achieving the above object, the technical solution adopted in the present invention is：Including body, it is used on body outer
Portion is working face to the face of the oil-filled effect of pressure sensor, and body is provided with multiple pin bores and an oil-filled hole,
Pin bores are located at collinear cylindric through hole head and the tail connection and constitute by many sections of diameter differences, center line, and
The diameter of the cylindric through hole gradually increases along the direction away from working face.
Preferably, the pin bores are made up of the cylindric through hole head and the tail connection of two-section.
Preferably, the working face be provided with it is multiple be easy to assembling pressure sensor clamp hole.
Preferably, the quantity for clamping hole is two.
Preferably, the quantity of the pin bores is five, and pin bores and oil-filled hole are uniformly distributed in same circumference
On.
Preferably, the pressure sensor also includes radiating sleeve, and radiating sleeve is a side opening, opposite side closing
Cylindric rubber sleeve, be provided with annular groove on working face, positioned at the periphery in pin bores and oil-filled hole, radiate
Set coats pin bores and oil-filled hole, and the edge of the opening side of radiating sleeve is placed in annular groove.
Preferably, concave station is provided with the inner wall edge of the opening side of the radiating sleeve, concave station is placed in annulus
In groove.
After above-mentioned technical proposal, the present invention has the positive effect that：
(1) pressure sensor of the invention, pin bores are made up of the cylindric through hole head and the tail connection of two-section, and circle
The diameter of columnar through holes gradually increases along the direction away from working face, the high-frequency and high-voltage in working environment repeatedly from
The face effect relative with working face comes, and pin bores are designed to into this kind of step structure, for preventing filling
Micro- molten glass in pin bores departs from sensor with pin；
(2) pressure sensor in the present invention, two is provided with working face and clamps hole, and pressure sensor is put
After being placed in in pressure head, clamp hole by two and pressure sensor is tightened into assembling with pressure head is entered；
(3) pressure sensor in the present invention, equipped with radiating sleeve, radiating sleeve cladding pin bores and oil-filled hole,
By pressure sensor with enter in pressure head welding process, radiating sleeve is played to the pin in pin bores and oil-filled hole
Protective effect, protection pin is not arrived by electron beam transpiration.

Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and detailed description.
As Figure 1-3, it is pressure sensor of the invention, including body 1, it is outside right to be used on body 1
The face of the oil-filled effect of pressure sensor is working face 11, and body 1 is provided with multiple pin bores 2 and one oil-filled
Hole 3.In the present embodiment, the quantity of pin bores 2 is five, and pin bores 2 and oil-filled hole 3 are uniformly distributed
On same circumference.The quantity of pin bores 2 can also be adjusted accordingly as needed.
Pin bores 2 are located at collinear cylindric through hole head and the tail connection group by many sections of diameter differences, center line
Into, and the diameter of the cylindric through hole away from the direction of working face 11 along gradually increasing.In the present embodiment,
Pin bores 2 are made up of the cylindric through hole head and the tail connection of two-section, and pin bores 2 can also be rationally changed to as needed
It is made up of three sections or more than three sections cylindric through hole head and the tail connections.Pressure sensor high frequency in the work environment
High pressure comes from the face effect relative with working face repeatedly, and pin bores 2 are designed to into this kind of step structure,
For preventing the micro- molten glass being filled in pin bores 2 and pin from departing from sensor.
Working face 11 be provided with it is multiple clamp hole 4, clamp hole 4 quantity be two.In use,
Pressure sensor is integrally embedded in pressure head, and working face 11 is concordant with the end face for entering pressure head, is clamped by two
