Abstract
The utility model relates to a pointer type spanner device capable of measuring torque force. The pointer type spanner device capable of measuring the torque force comprises a dial gauge type torque spanner, a torque multiplier, a torque spanner fixing device and a small inner-outer square spanner. One end of the dial gauge type torque spanner is connected with the small inner-outer square spanner, the lower end of the small inner-outer square spanner is connected with the torque multiplier which is sleeved on the torque spanner fixing device, and an outer square spanner arranged at the lower end of the torque multiplier stretches downward from the torque spanner fixing device. The pointer type spanner device capable of measuring the torque force can measure needed moment of force when a fastening piece is fastened, and effectively prevents the phenomenon that the fastening piece is scrapped caused by excessively large loaded torque force when the fastening piece is fastened from appearing.
Description
Technical field
The utility model relates to the wrench device in " securing member locking " field in industry-by-industries such as being applied to mining machinery, oilfield machinery, what be specifically related to is the wrench device that pointer-type can be surveyed torsional forces.
Background technology
Western developed country has just started the development to torque wrench at twentieth century four the fifties.Existing torque wrench generally is divided into two classes: adjusting torque spanner and wrest fixing spanner.The adjusting torque spanner can be divided into three groups again: manual torque spanner, pneumatic torque spanner and electrokinetic moment spanner.Wrest fixing spanner is widely used in having tightening technique the assembly line of strict demand, and this spanner makes each fastener torque value of product consistent, and the product quality of producing is secure.But in the mechanical fields such as oil field and mine, for large-scale fastening assembly line, adopt the manual mode of operation to carry out fastening always, and the manual moment of torsion that can apply by spanner of ordinary people generally is no more than 500Nm, the general sledgehammer that adopts impacts to realize operation, the situation of the fastening workpiece of a plurality of operators even usually occurs, and these modes of operation can't be measured fastening required moment, often overload situations occurs, cause securing member to scrap because exceeding yield strength.Simultaneously, such operating type not only labour intensity is large, production efficiency is low, and can produce violent vibrations and huge impulsive force, impact is installed or the maintenance progress, larger to adjacent parts damage, even directly destroy the mechanical balance of whole engineering structure, bring immeasurable loss.In addition, the work on the spot inclement condition of a lot of high pulling torque bolts, limited space, handwork can't be competent at all.
Summary of the invention
The purpose of this utility model is to provide the wrench device that pointer-type can be surveyed torsional forces, and this pointer-type can be surveyed the wrench device of torsional forces can't calculate torsional forces for the method that solves traditional fastening bolt, and causes securing member to be adjacent the problem of parts damages.
The utility model solves the technical scheme that its technical problem adopts: the wrench device that this pointer-type can be surveyed torsional forces comprises indication tabular form torque wrench, torque multiplier, torque wrench fixing device, little inside and outside cubic spanner, one end of indication tabular form torque wrench is connected with little inside and outside cubic spanner, the lower end of little inside and outside cubic spanner connects torque multiplier, torque multiplier is enclosed within on torque wrench fixing device, the torque multiplier lower end with outer cubic spanner from torque wrench fixing device, stretch out downwards.
In such scheme the torque multiplier lower end with outer cubic spanner with the spanner joint, be connected.
In such scheme, the spanner joint is connected with interior four hexagons.
In such scheme the torque multiplier lower end with outer cubic spanner with interior four hexagons, be connected.
The utlity model has following beneficial effect:
1, the utility model can be calculated securing member required moment of when locking, has effectively prevented when securing member is because of locking that the torsional forces excessive situation of scrapping that causes loaded occurs.
2, the utility model is by the use of torque multiplier, adopt the principle of lever, can be operated by a present people and replace original several individual mode of operation, this device quality of while is light, easy operating, reduced labour intensity, save the labour, and reduced economic loss to a great extent, improved product quality.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The little inside and outside cubic spanner of four hexagon 4 spanner joint 5 torque wrench fixing devices 6 in 1 indication tabular form torque wrench 2 torque multipliers 3.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As Fig. 1 shows, the wrench device that this pointer-type can be surveyed torsional forces comprises indication tabular form torque wrench 1, torque multiplier 2, torque wrench fixing device 5, little inside and outside cubic spanner 6, one end of indication tabular form torque wrench 1 is connected with little inside and outside cubic spanner 6, the lower end of little inside and outside cubic spanner 6 connects torque multiplier 2, torque multiplier 2 is enclosed within on torque wrench fixing device 5, torque multiplier 2 lower ends with outer cubic spanner from torque wrench fixing device 5, stretch out downwards.Little inside and outside cubic spanner 6 refers to that the two ends up and down of spanner are spanner, and wherein lower end is outer cubic spanner, and the upper end of spanner is interior cubic spanner.
In present embodiment, torque multiplier 2 lower ends with outer cubic spanner connect spanner joint 4, spanner joint 4 is connected with interior four hexagons 3, certain spanner joint 4 can also be connected with the spanner of other model.
In addition, the utility model can also be directly by torque multiplier 2 lower ends with outer cubic spanner with interior four hexagons 3, be connected.Interior four hexagons 3 refer to that the two ends up and down of spanner are spanner, and wherein lower end is interior cubic spanner, and the upper end of spanner is allen wrench.
While applying moment of torsion, hold the position of graduation mark in the middle of indication tabular form torque wrench 1 handle.Square toes firmly are connected with nut (bolt), the application of force on the direction that can only mark at indication tabular form torque wrench 1, and application of force direction should should relax during the application of force steadily in ± 15 °, must guard against impulsive force.
The utility model can be widely used in oilfield machinery, mining machinery, shipbuilding, metallurgy, chemical industry, bridge, etc. industry, particularly in the bolt-connection of some pressure pipings, pressure vessel and flange, there is compact conformation, the moment of torsion weight ratio is large, easy to operate, safe and reliable, be applicable to various working, can better help positive product quality, possess the advantage of promoting the use of.
