Description
Technical field
The utility model is related to a kind of tapping devices automatically examined and determine for pointer pressure.
Background technology
Pointer pressure is because its is simple in structure, easy to install and use, cheap, durable and without electricity consumption etc.
Advantage be widely used in industrial production, life links among.Although current some pointer pressure
It is substituted by digital pressure gauge, but still still mainstream, usage amount are huge for pointer pressure.Pointer pressure root
It is divided into compulsory verification and optional two kinds of calibrating according to the environment occasion used, it is mostly for safety to need the pressure gauge of compulsory verification
The pressure gauge in protection field, the pressure gauge of optional calibrating are mostly the monitoring pressure gauge of general technology pipeline, container.According to correlation
Regulation, the pressure gauge of compulsory verification are at least examined and determine once every half a year, and the pressure gauge of optional calibrating is also required to periodic verification, only not
The re-testing periods can voluntarily be determined using unit by crossing.
The calibrating of pressure gauge is generally sent to local qualified metering institutes using unit and does calibrating, due to pointer-type
Pressure gauge be widely used it is general, so, place metering the pressure gauge to be examined and determine every year of institutes quantity it is more, verification task
It is heavy.According to the vertification regulation of pressure gauge, each pressure calibration point in pressure gauge is needed to test friction error amount, method is
The pointer indicating value for recording a pressure gauge after being depressed into specified calibrating pressure spot is made, the watchcase of pressure gauge is then touched with hand, then
The pressure indicating value of pressure gauge after secondary record tapping, finally compares the friction error that the front and back indicating value of tapping calculates the calibrating pressure spot
Amount.The calibrating pressure spot that each pressure gauge generally requires detection is boosting and is depressured each 5 points, therefore examining and determine a pressure gauge need to
Pressure, tapping and record data are made manually many times, it is very cumbersome.
Invention content
The technical problem to be solved by the present invention is to provide a kind of tappings automatically examined and determine for pointer pressure
Device, it can substitute and manually be touched to dial plate, realize the effect of automatic pressure table calibrating, reduce the work of staff
It measures, has saved manpower, improve detection efficiency, and can effectively control percussion dynamics, ensure detection quality.
The technical scheme in the invention for solving the above technical problem is：
The utility model discloses a kind of tapping device automatically examined and determine for pointer pressure, it is characterised in that：Packet
Include be fixed in detection platform can universal adjustment strut, strut upper end is equipped with lateral electromagnet；The electromagnet peripheral hardware
There is shell that can be laterally movable；Percussion face one end of the enclosure is equipped with percussion tup；The enclosure both ends are forever
Magnet, shell can move back and forth under electric drive.
The electromagnet is that enameled wire is wound outside an iron core, and mounting hole is drilled among iron core；The strut passes through peace
Dress hole is fixedly connected with electromagnet.
The diameter of the shell is more than the diameter of electromagnet；The outer casing inner wall applies organic oil；The outer cover length is more than
The difference of electromagnet length, the outer cover length and electromagnet length is the stroke of tapping device.
The magnetic pole of described two permanent magnets is to be collectively aligned；When the electromagnet is powered, one end is attracted and other end quilt
Repel, shell movement is driven, to achieve the purpose that percussion；When the electromagnet no power, wherein the permanent magnet of one end can be inhaled
It is attached on the iron core of electromagnet, forms a kind of stable state, be unlikely to shake back and forth.
The percussion tup is soft rubber material.
The utility model has the beneficial effects that：
Compared with prior art, it is filled using the tapping of the utility model structure automatically examined and determine for pointer pressure
It sets and does not use resetting spring, when tapping without overcoming the resistance of resetting spring, lean on permanent magnet and the centre at both ends completely
Opposite pole between electromagnet is attracted each other and is repelled to realize percussion process, is positive force entirely, more energy efficient, this percussion side
Formula is effectively tapped instead of artificial, is realized the effect of automatic pressure table calibrating, is reduced the workload of staff, is saved
Manpower improves detection efficiency.
Compared with prior art, it is filled using the tapping of the utility model structure automatically examined and determine for pointer pressure
Set just can realize hammer action by electromagnet and permanent magnet, be related to the extremely simple novelty of structure, and easily controllable, can be preferably
Ground control taps dynamics, ensures detection quality.
Description of the drawings
Fig. 1 is the structural schematic diagram for the tapping device that the utility model is automatically examined and determine for pointer pressure.
Specific implementation mode
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments：
Referring to Fig. 1, the utility model provides a kind of tapping device automatically examined and determine for pointer pressure, including
