Abstract
The utility model relates to a torque type hydraulic machine for disassembly and assembly of screw nuts, which is composed of a hydraulic power source, a spanner main body, a reaction force arm, a sleeve barrel and a transmission pipeline for oil and electricity. A magnetic electrical contact manometer and an electromagnetic valve are arranged in the hydraulic power source, the spanner main body comprises an oil cylinder, a ratchet mechanism and a detent mechanism, the start position and the stop position of a piston rod in the oil cylinder are provided with a displacement sensor which is connected with the electromagnetic valve, and meanwhile, and the 1-3 teeth of the ratchet mechanism are contacted with the detent mechanism. The utility model has the advantages of small size, strong output torque, convenient operation and good reliability, the piston can automatically advance and recede, the big and small torque can be accurately controlled for the screw nuts with different specifications, and the use requirement can be ensured. The utility model is widely used for screw nuts and screw bolts which are provided with various specifications, particularly assembling and disassembling big screw nuts.
Description
The utility model relates to a kind of isolated plant that is used for the assembling and the dismounting of big specification nut, especially the moment of torsion formula hydraulic nut changer of being made up of hydraulic power supply, hydraulic spanner main body, the reaction arm of force, sleeve etc.
The assembling of nut bolt and dismounting are the work that a kind of amount is big and require great effort in various machinery equipments and the member, and especially for big specification nut, install and remove has become a difficult problem how fast and reliablely.Present domestic mounting or dismounting nut is mainly gone back the armrest wrench, though use simple, easy to carry, cost is low, the operation waste time and energy, the dismounting big nut can't be realized.Also occurred the torque wrench that surges in recent years,, applied unidirectional torque, nut has been installed and removed, had tangible progress by hydraulic jack driving pawl detent mechanism.But this torque wrench that surges, moving control of the advance and retreat armrest of piston or travel switch control in the oil cylinder, thereby operation is more numerous, accuracy, reliability are relatively poor, the size of moment of torsion is difficult to control and guarantees, simultaneously ratchet only contacts with a hook tooth, thereby output torque also is restricted, otherwise must increase volume.
The purpose of this utility model is to overcome weak point of the prior art, provides a kind of volume little, and moment of torsion is big, and is easy and simple to handle, reliable, and result of use is good, and can be applied to the moment of torsion formula hydraulic nut changer of plurality of specifications nut.
The technical solution of the utility model is: moment of torsion formula hydraulic nut changer mainly is made up of hydraulic power supply, hydraulic spanner main body, the reaction arm of force, sleeve and oil, electric feed-line.Hydraulic power supply can be that hand oil pump drives, and also can be that electric oil pump drives.The hydraulic spanner main body contains oil cylinder and ratchet, detent mechanism.Be characterized in being provided with in the hydraulic power supply magnetic that links to each other with petroleum pipeline and help electro connecting pressure gauge and magnetic valve, the Pressure gauge limit value can be set as required, to guarantee different size nut required torque.The corresponding site that piston rod rises in the described oil cylinder, stop bit is put is provided with displacement transducer, and this displacement transducer is electrically connected with magnetic valve, and the advance and retreat of piston are carried out automatically.Described ratchet centre becomes matched in clearance with sleeve, and ratchet contacts with 1～3 hook tooth simultaneously.
Described displacement transducer is a non-contact displacement transducer, and the part that matches with sleeve in the ratchet centre is hexagonal internal bore or is the hexagon spindle nose that is located at both sides.
The utility model is owing to adopt non-contact displacement transducer, contactless, collisionless, and piston is advanced and retreat automatically, and is accurately and reliably, easy and simple to handle.Used magnetic helps electro connecting pressure gauge, can preestablish force value, can accurately control the required torque size, guarantees result of use.Simultaneously ratchet contacts with a plurality of hook tooths, can be under the little situation of volume transmitting large torque.In addition, sleeve exchanging is convenient, can be applicable to the mounting or dismounting of plurality of specifications nut, and a changer is inserted in nut or bolt head from positive and negative two sides, and the reaction arm of force is bearing on the reliable fulcrum, just can carry out the assembling and the dismounting of nut bolt respectively.
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
Fig. 1 is a composition structural representation of the present utility model;
Fig. 2 is the structural representation after hydraulic spanner main body and the combination of the reaction arm of force;
Fig. 3 is provided with the ratchet schematic diagram of hexagon spindle nose for both sides.
As figure, hydraulic power supply 1 links to each other with hydraulic spanner main body 4 with signal transmssion line 3 by petroleum pipeline 2, and the reaction arm of force 5 is rigidly connected with wrench body 4.Be provided with the magnetic that links to each other with petroleum pipeline in the hydraulic power supply and help electro connecting pressure gauge 6 and magnetic valve 7, power source has roller, and it is convenient to promote.Contain oil cylinder 8, ratchet 9 and ratchet 10 in the hydraulic spanner main body 4, the corresponding site that the oil cylinder piston bar rises, stop bit is put is provided with displacement transducer 11.This displacement transducer is electrically connected with magnetic valve, adopts the Hall switch displacement transducer, is fit to common occasion.Two teeth of ratchet 9 contact with ratchet 10, and it is big to transmit moment of torsion.The center of ratchet 9 is a hexagonal internal bore, with sleeve 12 matched in clearance.Ratchet 13 is a modified, and its both sides are provided with the hexagon spindle nose and cooperate with relevant sleeve.Different size nut or bolt are assembled or dismantle, press the numerical value that the nut specification can pre-set Pressure gauge 6, accurately the size of control torque.
