Description
Technical field:
The present invention relates to the hydraulics field of equipment, is a kind of oil hydraulic cylinder displacement transducer protective equipment specifically; Be mainly used on the oil hydraulic cylinder with displacement transducer, protection displacement transducer is avoided infringement, and is easy to dismounting, is not prone to loose or dislocation risk.
Background technique:
At present, with the oil hydraulic cylinder of displacement transducer, in every field, be widely used, for producing and people's life has brought efficient intensive and efficient and convenient.Magnetostrictive displacement sensor is a kind of displacement transducer generally using in industrial production, the advantages such as precision is high, good stability, long range measurements that it has; Sensors with auxiliary electrode were electronic head is arranged on oil hydraulic cylinder afterbody, needs a protective housing to protect it, guarantees that it is not damaged, and Waterproof, moistureproof and dustproof; The mounting type of guard shield is bolton connection now, and at oil hydraulic cylinder afterbody, displacement transducer one circle thread mill drilling, connects together guard shield guard bit displacement sensor with cylinder body with bolt.But when reality is used, vibration or the reason such as Whole Equipment vibration while moving due to oil hydraulic cylinder, guard shield bolt is often loosening, cause guard shield to come off, be pressed onto on displacement transducer signal line, cause the faults such as line impairment, Joint's falling off, affect the safe direct motion of equipment and production; Loosening due to bolt in addition, can water inlet oil-feed in guard shield, causes joint short circuit, sensor scaling loss; And guard shield need to often disassemble sensor is checked to confirmation, can not directly shut.
The perforator background rise and fall roller oil hydraulic cylinder of take is example: this oil hydraulic cylinder displacement transducer is magnetostrictive displacement sensor, its guard shield is bolton and installs---and displacement transducer one circle has the screw hole of 6 M4, in interior side pressure one sealing, on the fixing cylinder body of the bolt of guard shield by 6 M4X20, it is upper that guard shield edge is pressed in sealing, guarantees that protection is good.During the action of this oil hydraulic cylinder, impact larger, and rise and fall roller overall operation while using vibration also larger, its mounting point displacement transducer, often occurs that the guard shield that bolt looseness causes comes off, and comes off and must break signal line down; Signaling line breaks or joint pulls open, and all can cause dance roller dropout, causes equipment downtime, and repair time is longer; And existing guard shield is when needs are safeguarded, around pipeline is more for oil hydraulic cylinder, and position is near ground, and people can not see at all, and dismounting screw is difficulty comparatively, installs more difficultly to screw eye, causes maintenance time longer.
Summary of the invention:
The object of the invention is to overcome the deficiency of above-mentioned prior art, and a kind of oil hydraulic cylinder displacement transducer protective equipment is provided, mainly solve the problem that existing protective housing easily comes off, installing/dismounting difficulty affects the normal operation of equipment.
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 comprised of bearing and safe edge two-part, on bearing, symmetry is established two grooves, between two grooves, 90 ° of directions are established two locating slots identical with groove width, at support outer, establish safe edge; Protective housing is installed on bearing, outer, protective housing top symmetry is established two catchings, the position of catching and the groove on bearing match, in protective housing inside by baffle ring holddown spring, baffle ring is tightened in catching by spring force pressure, on baffle ring, be processed with two breach, the locating slot on two gap positions and bearing matches; In protective housing outer, there is seal ring mounting groove.
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 and installation, is conducive to regular maintenance, convenient and swift; 3, solve production scene problem, avoided coming off of guard shield, effectively guaranteed equipment stable operation.
Accompanying drawing explanation:
Fig. 1 is the structural representation of pedestal of the present invention;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is protective acoustic cover assembly structural representation of the present invention;
Fig. 4 is the structural representation of baffle ring of the present invention.
Embodiment:
For Comprehension and Implementation better, below in conjunction with accompanying drawing, provide specific embodiment and describe the present invention in detail; Illustrated embodiment is only for explaining the present invention, not for limiting the scope of the invention.
Embodiment 1, referring to 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 has 90 ° of directions between 3, two grooves 3 of two grooves to have two locating slots 4 identical with groove 3 width; Two catchings 7 of protective housing 6 outer, top symmetries, catching 7 matches with groove 3, locating slot 4 on bearing 2, and there is seal ring mounting groove 11 protective housing 6 outers, and stuffing box mounting hole 12 is arranged at bottom; On baffle ring 8, be processed with two breach 10, baffle ring breach 10 installation corresponding to catching 7; Water proof and dust proof safe edge 5 is enclosed within on bearing 2, keeps two concentric composition pedestals 1 welded together of part; Spring 9 is put into protective housing 6, baffle ring breach 10 is aimed at catching 7, baffle ring 8 is pressed into the interior rear rotation of protective housing 6, spring 9 compressing cards in protective housing 6 inside, baffle ring 8 is tightened in catching 7 by spring force pressure, then in seal ring mounting groove 11, install seal ring, on stuffing box mounting hole 12, install stuffing box, form protective acoustic cover assembly 13; Protective acoustic cover assembly 13 is installed on pedestal 1, is formed 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, tightens after Bolt to position, directly pedestal 1 is welded on oil cylinder, prevents from coming off; After penetrating signaling line and displacement transducer in protective housing and being connected firmly, the groove 3 that catching on protective acoustic cover assembly 13 7 is aimed on bearing 2 advances inwards, to top, rear choosing turns 90 °, spring force is clamped on protective housing 6 in locating slot 4, gap between safe edge 5 and protective housing 6 is filled up in now sealing, guarantee that protective housing can not shake and come off, guarantee again good seal.Displacement transducer protective equipment of the present invention, as be applied on new oil cylinder, can when processing cylinder body, the structure of bearing 2 be machined directly on cylinder body, then weld upper safe edge 5, the form of protective acoustic cover assembly 13 is constant, and mounting type is constant.Protective housing 6 processing, if spring 9, baffle ring 8 are pressed in protective housing 6 in advance, baffle ring breach 10 can not processed.
