Abstract
The invention discloses a torque wrench shell, which is characterized in that the whole torque wrench shell is of a gun shape; the torque wrench shell comprises horizontal parts, vertical parts, a left side plate, a right side plate and a wear resistant ring; the horizontal parts and the vertical parts are vertical to each other; the left side plate and the right side plate are arranged symmetrically; each of the left side plate and the right side plate is gun-shaped; the whole torque wrench shell is formed by encircling the left side plate and the right side plate together through bolts in a connecting way; a hydraulic cylinder shell is arranged at the horizontal parts of the left side plate and the right side plate; the hydraulic cylinder shell is used for installing a hydraulic cylinder; an installation hole, which is used for installing a sleeve, is formed in the vertical parts of the left side plate and the right side plate; the wear resistance ring sleeves the sleeve. The torque wrench shell disclosed by the invention has the advantages of simple manufacture technology, high operability, low production cost, economy, affordability, compact structure and small size, and can be especially suitable for a hollow hydraulic wrench which is used in the fields of electric power, ship, metallurgy, transportation, cement, building and aviation.
Description
Technical field
The application relates to hydraulic tool field, particularly a kind of torque wrench shell.
Background technology
Hydraulic torque wrench is power with hydraulic pressure, provides high pulling torque to export, for the installation of bolt and the professional bolt tightening tool of dismounting, through being commonly used to tighten and dismantle the bolt being greater than an inch.Hydraulic torque wrench is made up of working head, hydraulic pump and high-pressure oil pipe.By high-pressure oil pipe, hydraulic pump transmits power to working head, drives tightening or unclamping of working head rotating nut.Hydraulic pump can by electric power or compressed air-driven.
The advantage of hydraulic torque wrench is to provide its continuous print being connected to the driving element of threaded fastener (as bolt, nut, and like) and rotates, and provides the continuous print of these tightening members to rotate and fastening.In some existing hydraulically operated torque wrenches, be typically provided with two hydraulically operated cylinder-piston unit, they are formed the unit of separation and are connected with a ratchet-linkage.This separation structure of cylinder-piston unit needs a large-sized especially corresponding spanner, so the existing hydraulically operated torque wrench size of above-mentioned universal class is large.Hollow hydraulic spanner thinner thickness, is specially adapted to the place that space is narrower and small, is applicable to the field such as electric power (nuclear power, wind-powered electricity generation, water power, thermoelectricity), boats and ships, metallurgy, traffic, cement, building, aviation.The all exposed settings such as existing hydraulic jack, the arm of force, sleeve, ratchet and counter-force arm, volume is large, structure is not compact, and machine components that are compact for tension structure, narrow space are just inapplicable.
Summary of the invention
The technical problem that the application will solve is for above-mentioned the deficiencies in the prior art, and provides a kind of torque wrench shell.
For solving the problems of the technologies described above, the technical scheme that the application adopts is:
A kind of torque wrench shell, torque wrench housing integration is pistol-shaped, comprise orthogonal horizontal part and vertical portion, described torque wrench shell comprises left plate, right plate and wear ring, left plate and right plate are symmetrical arranged, left plate and right plate are all in pistol-shaped, and to be linked together left plate and right plate by bolt the monolithic case enclosing and form torque wrench; The horizontal part of left plate and right plate is provided with hydraulic jack housing, hydraulic jack housing, for installing hydraulic jack, the vertical portion of left plate and right plate is offered the installing hole for installing sleeve, sleeve is arranged with wear ring.
Described sleeve is hex bolts type.
The vertical portion of described torque wrench shell is for installing escapement, and the bottom of escapement contacts with wear ring.
Described torque wrench enclosure material is chromium-plated steel.
Described torque wrench enclosure material is manganese steel.
The cup with column type pearl that the application provides has a significant effect:
1, torque wrench shell manufacture craft described in the application is simple, and operability is high, and production cost is low, economical and practical.
2, torque wrench shell described in the application, compact conformation, volume is little, is specially adapted to the field hollow hydraulic spanners such as electric power, boats and ships, metallurgy, traffic, cement, building, aviation.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present application or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the application, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 shows the overall structure of torque wrench shell described in the application;
Fig. 2 shows the left view of Fig. 1 and has carried out partial cross;
Wherein have: 2. hydraulic jack housing; 4. wear ring; 11. left plates; 12. right plates; 31. sleeves; 111. installing hole.
Detailed description of the invention
For making the object of the application and technical scheme clearly, be clearly and completely described below in conjunction with the technical scheme of the embodiment of the present application to the application.Obviously, described embodiment is a part of embodiment of the application, instead of whole embodiments.Based on the embodiment of described the application, the every other embodiment that those of ordinary skill in the art obtain under without the need to the prerequisite of creative work, all belongs to the scope of the application's protection.
As shown in Figure 1, 2, a kind of torque wrench shell, torque wrench housing integration is pistol-shaped, comprise orthogonal horizontal part and vertical portion, described torque wrench shell comprises left plate 11, right plate 12 and wear ring 4, left plate 11 and right plate 12 are symmetrical arranged, and left plate 11 and right plate 12 are all in pistol-shaped, and to be linked together left plate 11 and right plate 12 by bolt the monolithic case enclosing and form torque wrench; The horizontal part of left plate 11 and right plate 12 is provided with hydraulic jack housing 2, hydraulic jack housing 2, for installing hydraulic jack, the vertical portion of left plate 11 and right plate 12 is offered the installing hole 111 for installing sleeve 31, sleeve 31 is arranged with wear ring 4.
Described sleeve 31 is hex bolts type, is convenient to clamping.
The vertical portion of described torque wrench shell, namely the vertical portion of left plate 11 and right plate 12 is for installing escapement, and the bottom of escapement contacts with wear ring 4.
