Description
Technical field
The utility model relates to the control device of using in the metal plate and belt foil mill hydraulic pressure automatic thickness control system, particularly relates to a kind of position transducer.
Background technology
Present magnetic rod-type position transducer normally magnetic bar is fixed, inductive coil is done relative motion with testee and magnetic bar, because inductive coil is to be fixed in the tested moving object, therefore the movement locus of moving object with the axis of fixing magnetic bar is necessary parallel can not be crooked, otherwise will influence measuring accuracy.In addition; the shell of sensor can only be simply dustproof, and this magnetic rod-type position transducer is installed in pressing on the oil cylinder of rolling metal process equipment, under the operating mode of a large amount of emulsions that contain metal powder or keryl liquid spraying; its shell does not have the seal protection effect, can't satisfy request for utilization.
Summary of the invention
The purpose of this utility model provides a kind of magnetic rod-type position transducer, and generation is crooked when making the moving component motion can not influence measuring accuracy yet.
The purpose of this utility model also is to solve the sealing problem when measuring.
For achieving the above object, the utility model adopts following technical scheme: magnetic rod-type position transducer comprises a housing, cover in the sensor that can penetrate cable is housed in the housing, in sensor, put and be provided with the inlet wire groove, the magnetic head seat is equipped with in the set upper side in the sensor, on the magnetic head seat inductive coil is housed, at the housing internal upper part guide ring is housed, the orienting sleeve bottom is sleeved in the guide ring and can moves up and down along guide ring, contact is equipped with in the orienting sleeve upper end, magnetic bar upper end is fixed on the contact, and free end passes magnetic head seat center pit vertically downward, between cover and the orienting sleeve stage clip is housed in the sensor.
The cover lower end is provided with entrance hole in sensor, and the cover peripheral hardware is useful on the line ball sleeve pipe of fixing cord in the sensor.
The upper end is provided with the location-plate that is used for the contact location in orienting sleeve.
Be provided with rubber sealing boot between housing and contact, cover is provided with O-ring seal with the housing junction in the sensor.
The top of contact is spherical.
Since the utility model with the sensor sensing coil stationary on the magnetic head seat, one aperture is arranged in the middle of the magnetic head seat, slightly larger in diameter in the magnetic shank diameter less than the inductive coil endoporus, the magnetic bar passes the magnetic head seat and is fixed on moving linearly on the contact, by the aperture guiding of orienting sleeve and magnetic head seat, make it be maintained fixed constant with relative radial position relationship between the inductive coil.Compression by spring closely contacts with moving component, and contact is a spheroid, in the time of therefore can not moving because of moving component when measuring the crooked measuring accuracy that influences does not take place, and has guaranteed the measurement mechanism reliability during operation.Because inductive coil is contained in the interior cover of sensor and each connecting portion all seals, therefore contamination resistance strengthens greatly, can satisfy the normal use of magnetic rod-type position transducer under the high pollution working condition, improve measuring reliability, prolong the serviceable life of sensor.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, magnetic rod-type position transducer comprises a housing 5, cover 2 in the sensor is housed in the housing 5, the cover lower end is provided with entrance hole 16 in sensor, cable 15 can penetrate in entrance hole 16, put in sensor and be provided with inlet wire groove 13, cover 2 peripheral hardwares are useful on the line ball sleeve pipe 3 of fixing cord in sensor.For ease of the wiring operation, can in sensor, overlap the lower end one end cap 1 is set, finish the bonnet upper end cover in wiring and guarantee sealing.Magnetic head seat 8 is equipped with in cover 2 upper ends in the sensor, and inductive coil 12 is housed on the magnetic head seat 8, and an aperture is arranged in the middle of the magnetic head seat, slightly larger in diameter in the magnetic shank diameter less than the inductive coil endoporus.At housing 5 internal upper parts guide ring 7 is housed, orienting sleeve 6 is sleeved in the guide ring 7 and can moves up and down along guide ring 7, has guaranteed that magnetic bar 14 can move along a straight line.Contact 11 is equipped with in orienting sleeve 6 upper ends, the upper end is provided with the location-plate 10 that is used for contact 11 location in orienting sleeve 6, globulate is done at contact 11 tops, makes it to be some contact with contacting of moving component, thereby makes the magnetic bar crooked when avoiding owing to the testee run-off the straight.Magnetic bar 14 upper ends are fixed on the contact 11, and free end passes magnetic head seat 8 vertically downward.Between cover 2 and the guide pin bushing 6 spring 4 that certain pre compressed magnitude is arranged is housed in the sensor, the magnetic bar can be stretched out under the effect of spring force in resilience.
For realizing excellent sealing, between housing 5 and contact 11, be provided with rubber sealing boot 9, and be provided with O-ring seal in each junction.
During use, cable 15 cover 2 lower ends in the sensor penetrate, and along inlet wire groove 13 upwards in the sensor cover 2 upper ends pass with inductive coil 12 and be connected.The testee motion makes the motion of contact pressurized, makes magnetic bar and coil produce relative motion, produces transducing signal and is exported by cable.
