The utility model discloses a pressure sensor has solved the hidden danger that the pin drops easily, improves work efficiency.
Description
Technical field
The invention belongs to mechanical field, be specifically related to a kind of pressure transducer.
Background technology
At present, pressure transducer and entrance pressure head are welded together generally adopt electron beam welding machine to weld.Wherein, the structure of pressure transducer is generally such: the side of welding with entrance pressure head is a plane, plane has some pins and an oil-filled hole, fixes the form of some pin bores employing cylindrical holes of pin for filling glass.When entrance pressure head coordinates with pressure transducer, entrance pressure head and sensor carry out tightening coordinating by inconvenience; When entrance pressure head and pressure transducer are in EBW (electron beam welding) process, there is the problem of pin protection inconvenience in this structure; When entrance pressure head and pressure transducer are in working environment, there is hidden danger that pin may come off (under the effect of high pressure and dither in this structure, fill micro-molten glass may and sensor base between no longer tightly adhesion, may come off with pin).These problems finally can affect the working effect of entrance pressure head, may cause high risks.
Summary of the invention
The object of this invention is to provide a kind of pressure transducer, solve pin and hold caducous hidden danger, increase work efficiency.
For achieving the above object, the technical solution adopted in the present invention is: comprise body, body is workplace for the face of outside to the oil-filled effect of pressure transducer, body is provided with multiple pin bores and an oil-filled hole, pin bores is positioned at collinear cylindric through hole head and the tail by many sections of diameter differences, center line and connects to form, and the diameter of described cylindric through hole increases gradually along the direction away from workplace.
Preferably, described pin bores is connected to form by the cylindric through hole head and the tail of two-section.
Preferably, described workplace be provided with multiple be convenient to assembling pressure sensor clamp hole.
Preferably, the quantity clamping hole described in is two.
Preferably, the quantity of described pin bores is five, and pin bores and oil-filled hole are uniformly distributed in circumferentially same.
Preferably, described pressure transducer also comprises radiating sleeve, the cylindric rubber sleeve that radiating sleeve is a side opening, opposite side is closed, on workplace, be positioned at pin bores and the outer of oil-filled hole is arranged with annular groove, the coated pin bores of radiating sleeve and oil-filled hole, and the edge card of the opening side of radiating sleeve is placed in annular groove.
Preferably, the inner wall edge place of the opening side of described radiating sleeve is provided with concave station, and concave station is placed in annular groove.
After adopting technique scheme, the present invention has following good effect:
(1) pressure transducer of the present invention, pin bores is connected to form by the cylindric through hole head and the tail of two-section, and the diameter of cylindric through hole increases gradually along the direction away from workplace, high-frequency and high-voltage in working environment is come from the face relative with workplace effect repeatedly, pin bores being designed to this kind of step structure, being filled in the micro-molten glass in pin bores and pin separating sensor for preventing;
(2) pressure transducer in the present invention, workplace is provided with two and clamps hole, and pressure transducer is positioned over after in entrance pressure head, clamps hole pressure transducer and entrance pressure head are tightened assembling by two;
(3) pressure transducer in the present invention; radiating sleeve is housed, the coated pin bores of radiating sleeve and oil-filled hole, by pressure transducer and entrance pressure head welding process; radiating sleeve plays a protective role to the pin in pin bores and oil-filled hole, and protection pin is not arrived by electron beam transpiration.
Accompanying drawing explanation

The cut-open view in the A-A direction that Fig. 2 is pressure transducer shown in Fig. 1;
Fig. 3 is the structural drawing of the radiating sleeve in the present invention.
Wherein: 1, body, 11, workplace, 2, pin bores, 3, oil-filled hole, 4, clamp hole, 5, radiating sleeve, 51, concave station, 6, annular groove.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As Figure 1-3, be pressure transducer of the present invention, comprise body 1, body 1 is workplace 11 for the face of outside to the oil-filled effect of pressure transducer, and body 1 is provided with multiple pin bores 2 and an 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 in circumferentially same.The quantity of pin bores 2 can also adjust accordingly as required.
Pin bores 2 is positioned at collinear cylindric through hole head and the tail by many sections of diameter differences, center line and connects to form, and the diameter of described cylindric through hole increases gradually along the direction away from workplace 11.In the present embodiment, pin bores 2 is connected to form by the cylindric through hole head and the tail of two-section, rationally can also change to pin bores 2 as required and be connected to form by more than three sections or three sections cylindric through hole head and the tail.Pressure transducer high-frequency and high-voltage is in the work environment come from the face relative with workplace effect repeatedly, pin bores 2 being designed to this kind of step structure, being filled in the micro-molten glass in pin bores 2 and pin separating sensor for preventing.
Workplace 11 is provided with and multiplely clamps hole 4, and the quantity clamping hole 4 is two.In use, in pressure transducer embed wholly entrance pressure head, workplace 11 is concordant with the end face of entrance pressure head, clamps hole 4 by two, and pressure transducer and entrance pressure head are tightened.
Pressure transducer also comprises radiating sleeve 5, the cylindric rubber sleeve that radiating sleeve 5 is a side opening, opposite side is closed.On workplace 11, be positioned at pin bores 2 and the outer of oil-filled hole 3 is arranged with annular groove 6, the inner wall edge place of the opening side of radiating sleeve 5 is provided with concave station 51, and concave station 51 is placed in annular groove 6, and the coated pin bores of radiating sleeve 52 and oil-filled hole 3.By in pressure transducer and entrance pressure head welding process, the pin in radiating sleeve 5 pairs of pin bores 2 and oil-filled hole 3 play a protective role, and protection pin is not arrived by electron beam transpiration.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of application claims.
