Description
Technical field:
The present invention relates to the technical field of hydraulic pressure of equipment, specifically a kind of oil hydraulic cylinder displacement transducer protective equipment; Be mainly used in being with on the oil hydraulic cylinder of displacement transducer, protection displacement transducer from infringement, and is easy to dismounting, not easily occurs loose or dislocation risk.
Background technique:
At present, the oil hydraulic cylinder of band displacement transducer is widely used in every field, for produce and the life of people brings Highly Effective and efficient and convenient.Magnetostrictive displacement sensor is a kind of displacement transducer generally used in industrial production, the advantages such as precision is high, good stability, long range measurements that it has; Sensors with auxiliary electrode electronic head is arranged on oil hydraulic cylinder afterbody, needs a protective housing to protect it, ensures that it is not damaged, and Waterproof, moistureproof and dustproof; The mounting type of present guard shield is bolton and connects, and namely at oil hydraulic cylinder afterbody, displacement transducer one encloses thread mill drilling, is connected together by guard shield with bolt with cylinder body, guard bit displacement sensor.But when reality uses, due to the reason such as vibration or Whole Equipment vibration during oil hydraulic cylinder action, guard shield bolt often loosens, guard shield is caused to come off, be pressed onto on displacement transducer signal line, cause the fault such as line impairment, Joint's falling off, affect the safe direct motion of equipment and production; Loosening in addition due to bolt, oil-feed of intaking in guard shield, causes joint short circuit, sensor scaling loss; And guard shield needs often to disassemble and carries out inspection to sensor and confirm, can not directly shut.
For perforator background rise and fall roller oil hydraulic cylinder: this oil hydraulic cylinder displacement transducer is for magnetostrictive displacement sensor, its guard shield is bolton and installs---and displacement transducer one circle has the screw hole of 6 M4, seal in interior side pressure one, on the cylinder body that the bolt that guard shield passes through 6 M4X20 is fixed, guard shield edge is pressed in sealing, ensures that protection is good.Impact comparatively large during this oil hydraulic cylinder action, and when rise and fall roller overall operation uses, vibration is also larger, its mounting point displacement transducer down, often occurs that the guard shield that bolt looseness causes comes off, comes off and must break signal line; Signaling line breaks or joints apart, all can cause dance roller dropout, cause equipment downtime, and repair time is longer; And existing guard shield is when needs are safeguarded, around oil hydraulic cylinder, pipeline is more, position is near ground, and people can not see at all, and dismounting screw is comparatively difficult, installs screw eye more difficult, causes maintenance time longer.
Summary of the invention:
The object of the invention is the deficiency overcoming above-mentioned prior art, and a kind of oil hydraulic cylinder displacement transducer protective equipment is provided, mainly solve that existing protective housing easily comes off, installing/dismounting difficulty affects the problem that equipment normally runs.
Technological scheme of the present invention is: a kind of oil hydraulic cylinder displacement transducer protective equipment, its special way is, it comprises pedestal, pedestal is made up of bearing and safe edge two-part, on bearing, symmetry establishes two grooves, between two grooves, two locating slots identical with groove width are established in 90 ° of directions, establish safe edge at support outer; Protective housing installed by bearing, outer, protective housing top symmetry establishes two catchings, groove on the position of catching and bearing matches, inner by baffle ring holddown spring at protective housing, baffle ring is tightened in catching by spring force pressure, baffle ring is processed with two breach, the locating slot on two gap positions and bearing matches; Seal ring mounting groove is had in protective housing outer.
Compared with the prior art a kind of oil hydraulic cylinder displacement transducer protective housing of the present invention has outstanding substantive distinguishing features and remarkable progress: 1, due to guard shield by a spring compression in draw-in groove, guard shield and oil cylinder are an overall structure, common vibrations can't cause coming off of guard shield, can not affect the normal operation of sensor; 2, for convenience detach with installation, be conducive to regular maintenance, convenient and swift; 3, solve production scene problem, avoid coming off of guard shield, the stable operation of effective guarantee equipment.

Embodiment:
In order to Comprehension and Implementation better, provide specific embodiment below in conjunction with accompanying drawing and describe the present invention in detail; Illustrated embodiment, only for explaining the present invention, is not for limiting the scope of the invention.
Embodiment 1, see Fig. 1,2,3,4, is processed into bearing 2, safe edge 5, protective housing 6, baffle ring 8, spring 9; On bearing 2, symmetry to have between two grooves, 3, two grooves 3 90 ° of directions have two locating slots 4 identical with groove 3 width; Two catchings 7 of outer, protective housing 6 top symmetry, catching 7 matches with the groove 3 on bearing 2, locating slot 4, and there is seal ring mounting groove 11 protective housing 6 outer, and stuffing box mounting hole 12 is arranged at bottom; Baffle ring 8 is processed with two breach 10, baffle ring breach 10 is corresponding with catching 7 to be installed; Water proof and dust proof safe edge 5 is enclosed within bearing 2, keeps two concentric composition pedestals 1 welded together of part; Spring 9 is put into protective housing 6, baffle ring breach 10 aims at catching 7, baffle ring 8 is pressed into after in protective housing 6 and rotates, spring 9 compressing card is inner at protective housing 6, baffle ring 8 is tightened in catching 7 by spring force pressure, then in seal ring mounting groove 11, install seal ring, stuffing box mounting hole 12 installs stuffing box, composition protective acoustic cover assembly 13; Pedestal 1 is installed protective acoustic cover assembly 13, forms oil hydraulic cylinder displacement transducer protective equipment of the present invention.
Oil hydraulic cylinder displacement transducer protective equipment of the present invention, during use, first aims at original tapped hole on oil hydraulic cylinder by the bolt hole of pedestal 1, after tightening Bolt to position, is directly welded on oil cylinder by pedestal 1, prevents from coming off; Penetrate after signaling line and displacement transducer be connected firmly in protective housing, the groove 3 that catching 7 on protective acoustic cover assembly 13 is aimed on bearing 2 is advanced inwards, behind top, choosing turns 90 °, protective housing 6 is clamped in locating slot 4 by spring force, gap between safe edge 5 and protective housing 6 is filled up in now sealing, ensure that namely protective housing can not shake to come off, ensure good seal again.Displacement transducer protective equipment of the present invention, as being applied on new oil cylinder, can, when processing cylinder body, be machined directly on cylinder body by the structure of bearing 2, then the upper safe edge 5 of welding, the form of protective acoustic cover assembly 13 be constant, and mounting type is constant.Protective housing 6 is processed, if spring 9, baffle ring 8 are pressed in protective housing 6 in advance, baffle ring breach 10 can not be processed.
