Description
Technical field
The present invention relates to metal material test and all kinds of standard component field tests, particularly a kind of Multifunctional bolt fastening is
The integrated form pressure of system turns round duplex measurement device.
Background technology
It is the form of bolt-nut auxiliary connection that threaded fastener connection system is most widely used, and majority is applied at pretension
Under power effect, the connection under pretightning force can improve bolted reliability, and can strengthen the compactness of connected body with just
Degree.In threaded fastener connection system, when not having pretightning force or pretightning force inadequate, do not have real interconnection function, typically
Referred to as owe to twist；But too high pretightning force or super stubborn also result in threaded failure.Owing to erecting bed is difficult to directly
Measure pretightning force, so mostly the pretightning force of threaded fastener is then to use the means controlling moment of torsion and corner to realize.This just needs
It is to be understood that the torsion of the relation between the moment of torsion of threaded fastener, corner and pretightning force, i.e. threaded fastener (square)-draw (power) to close
System.
Threaded fastener is turned round-is established unprincipled connection, and is not only related to torque coefficient, coefficient of friction (containing thread friction coefficient and support
Face coefficient of friction), fastener shaft power, the test of fastening characteristics of a series of threaded connection pairs such as tightening torque and computational methods, also
Relate to fundamental terms, the regulation of symbol such as the stress sectional area of threaded fastener and the computational methods of loaded area.
Most crucial parts are turned round-established unprincipled connection to present analysis threaded fastener for drawing-turn round compound sensor, and this sensor manufactures difficulty
Degree is big, and the most domestic do not have manufacturing enterprise, will produce the Multifunctional bolt fastening point turned round for analysis thread securing member-establish unprincipled connection

Cost is the highest, seriously constrains securing member production, the analysis test to securing member performance of the use department, is unfavorable for securing member matter
The raising of amount, is also unfavorable for scientifical use securing member.The domestic measurement apparatus turned round for analyzing securing member-establish unprincipled connection mainly uses
Split-type structural form, i.e. dynamic torque sensor, load sensor, static torque sensor three separate, and measure it respectively
Total torque, clamp shaft power, screw thread width moment of torsion.Compound biography can will be drawn-be turned round to our company's patent (Authorization Notice No.: CN204165843U)
The function of sensor is realized by load sensor and the independently combinable of torque sensor, but is still that split type sensor group,
In test process, fixture quantity is many, and it is the most convenient to operate, and causes the testing time long, and bolt clamping is wasted time and energy, and is unfavorable for engineering
The problems such as application.
Summary of the invention

Hold, and be arranged on installation and put；Described test backing plate is close to the top of described test bolt and is arranged on the draw-in groove of load pad
In；Described load pad is stuck in the hole of load sensor by the step of self, described load sensor by with described installation
Step on the right side of set coordinates location and is bolted together, and described load sensor is by described load pad experiment with measuring spiral shell
The clamping force of bolt.
Further, described nut is fixed on the inside of bolted fixture, described nut stop cutting ferrule by nut stop cutting ferrule
And between bolted fixture, it is provided with spacer for bolt.
Further, described deep groove ball bearing is arranged on thrust ball bearing respective side or corresponding end, and with described load
Axle installed by set and installation set installing hole coordinates；Two centring rings of described thrust ball bearing respectively with described install set hole, location and
The locating shaft of load set matches.
Further, disc type static torque sensor door is bolted on described disc type static torque sensor；
Load sensor cover plate positions and is fixed by bolts to by described load pad on described load sensor.
Further, described installation set is rack-mount, and described support passes through key location and installation on seat board.
Useful the having the technical effect that of the present invention
Disc type static torque sensor and load sensor are carried out integrated, substitutes split type sensor group, decrease spiral shell
