Abstract
The invention discloses a hydraulic efficiency nut restorer. The hydraulic efficiency nut restorer comprises a cylinder body, a plunger piston, a gland and a gland nut, wherein the cylinder body is provided with a central column and a disk base; a hydraulic cavity in which the cylinder body is matched with the plunger piston is arranged on the disk base; the disk base is provided with an oil inlet; the gland is firmly connected with the central column; the gland is in threaded connection with the gland nut; and the extending end of the plunger piston is used for transferring generative power of the restorer. The hydraulic efficiency nut restorer can very conveniently realize restoration of hydraulic efficiency nuts and disassembly and assembly of the hydraulic efficiency nuts, has a reasonable and compact structure, and meets the requirements of quickly restoring, disassembling and assembling the hydraulic efficiency nuts.
Description
Technical field
The present invention relates to a kind of hydraulic nut resetting means.
Background technology
Hydraulic nut uses the gapped generation of back-plunger and cylinder body meeting first, has influence on the effect that secondary uses.In order to ensure the correct use of hydraulic nut, need to eliminate this gap.Usually adopt the method for static pressure to reach the purpose of eliminating the gap, but, cause the very difficulty that resets of hydraulic nut because the restriction of user's environment for use does not generally have suitable static pressure equipment.
Summary of the invention
The object of the present invention is to provide a kind of hydraulic nut restorer easy to use.
This hydraulic nut restorer provided by the invention comprises cylinder body, plunger, gland, clamp nut, and described cylinder body has newel and dish seat, and the hydraulic chamber that cylinder body cooperates with plunger has oil-in on this dish seat on described dish seat; Be fastenedly connected between gland and the described newel, be threaded between gland and the clamp nut, the external part of described plunger is used for the transfer function with restorer generation power.
In order to make this restorer after finishing the work of resetting for hydraulic nut, the discharging of the oil in the hydraulic chamber is clean, be with spring on the described newel, this spring action is in described plunger.
In order compression plate to be housed on the gland, be useful on the screw rod of the hydraulic nut of dismounting on this compression plate to hydraulic nut fast quick-detach and precisely installation when cleaning.
Elder generation took off the clamp nut of this restorer when the present invention used from gland, and hydraulic nut is set on this restorer, and first-class then clamp nut injects hydraulic oil in cylinder body, and plunger is risen, and hydraulic nut is resetted.The present invention is very easy to use, and cost is low, compact conformation, and volume is little.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
The present invention includes cylinder body 1, plunger 2, gland 3, clamp nut 4 as can be seen from Figure 1, cylinder body 1 has dish seat 12 and newel 11, the two can make one, the hydraulic chamber 14 that cylinder body 1 cooperates with plunger 2 is on dish seat 12, on this dish seat oil-in 13 is arranged, external oil pump can be by this oil-in to hydraulic chamber 14 delivery hydraulic pressure oil.Be with a spring 5 on the newel 11, gland 3 covers on the newel on 11 and together with this spring 5 and covers, and gland 3 is fastenedly connected by the top of bolt and newel 11.Plunger 2 is contained in the hydraulic chamber 14, and the external part of plunger 2 has an inner ring platform, an outer ring platform, the inner ring platform is accepted the active force of spring 5, makes this restorer after finishing the work of resetting for hydraulic nut, and plunger 2 is emitted the oil in the hydraulic chamber 14 by the effect of spring 5.The outer ring platform is used for the support hydraulic pressure nut.Clamp nut 4 is provided with and shakes handle 41, shakes handle by this clamp nut 4 is screwed on the gland 3, on the one hand plays position-limiting action in the resetting of hydraulic nut, and can install compression plate in the above additional on the other hand, is used for the dismounting hydraulic nut.Prepare a compression plate 6 during concrete enforcement, the screw rod installing hole is arranged on the compression plate 6, hydraulic nut is exerted pressure, realize the piston dismounting of hydraulic nut by screw rod.
Present embodiment can have following three functions: the one, and to the reset function of hydraulic nut: the left side referring to Fig. 1 is half of.Hydraulic nut A is enclosed within on this restorer by direction as shown, and this moment, the piston of hydraulic nut just in time dropped on the outer ring platform of plunger external part, and first-class clamp nut is to play the upwards position-limiting action to hydraulic nut.Hydraulic oil (can use hydraulic hand-pump) is sent in all ready beginnings in hydraulic chamber 14, plunger is moved up, the piston of hydraulic nut also upwards resets thereupon, and pressurize is 3-5 minute when reaching the return stroke of regulation, guarantees that hydraulic nut resets to put in place.Reset after hours, pressure release, 5 pairs of plungers 2 of spring this moment are exerted pressure, and discharging is clean automatically with the oil in the hydraulic chamber.
The 2nd, to the disassembling function of hydraulic nut: inside needed to clean after hydraulic nut used a period of time.The dismounting hydraulic nut also can be realized with restorer of the present invention.This moment, hydraulic nut A should reverse end for end to install conversely, made it piston upwards, and is half of referring to the right side of Fig. 1.Compression plate 6 is contained on the gland, with 4 screw rod 61(M 12) 4 ф 13 unthreaded holes by compression plate are tightened on 4 M12 screws of hydraulic nut piston, be spun on the M12 screw rod with 4 M12 nuts being with at random respectively again, then with respectively uniform fastening four the M12 nuts of special spanner, the tractive force of dependence bolt withdraws from the piston positive of hydraulic nut, begins then to clean.
The 3rd, the assembling function of hydraulic nut: hydraulic nut will assemble recovery after cleaning and finishing, to lubricate the even coating lubricant of face earlier, intact sealing is fixed on the hydraulic nut on request, and assembling back, artificial location is placed on (right side referring to Fig. 1 is half of) on the restorer by the diagram requirement.Withstand on at random 4 M12 bolts 4 M12 screws by compression plate on the pit of 4 ф 13 of hydraulic nut plunger.Screw 4 M12 bolts respectively with special spanner, rely on the pressure of bolt that the hydraulic nut plunger is forced jacking.
Therefore the present invention can not only be advantageously used in resetting of hydraulic nut, can also be used for its dismounting and assembling, and effectively prolonged the service life of hydraulic nut.
