Description
Technical field
The utility model belongs to machinery field, is related to a kind of torque coefficient detecting instrument for high-strength bolt auxiliary connection,
Specifically a kind of axle power detection device on high-strength bolt torque coefficient detection testing machine.
Background technique
The torque coefficient of high-strength bolt is obtained by the corresponding calculation of axial force of torque and bolt tightened to nut,
It is tightened when test by applying torque to nut, the axle power that bolt generates is transmitted to spoke type pressure sensing by sliding block and screw rod
The corresponding axle power of corresponding torque is measured on device.The lateral force that tightening nuts generate can to generate and lead with bolted sliding block
To the pressure between slot, to increase the frictional force of sliding block and guide groove, and then the accuracy of axial force test is influenced.
Summary of the invention
Testing machine is detected for high-strength bolt torque coefficient in view of the above problems, the purpose of the utility model is to provide one kind
On axle power detection device, change traditional axle power meter structure, reduce the frictional force of sliding block and guide groove, reduce frictional force pair
The influence of the measured value of axle power, to improve the accuracy of torque coefficient result.
The purpose of this utility model is achieved through the following technical solutions:
A kind of axle power detection device on high-strength bolt torque coefficient detection testing machine, including connection tested bolt
Sliding block is equipped with guide groove in the outside of sliding block, and one end of sliding block is connect by stretching screw with axial force sensor；Sliding block it is another
End is connect by snap-gauge with tested bolt；It is characterized by: sliding block and guide groove are cooperated using circular configuration, along round guide groove
Direction is equipped with notch, and sliding block is connect by positioning pin with the needle bearing being mounted in notch.
In the utility model, it is equipped with notch along round guide groove direction two sides, sliding block is by positioning pin and is mounted on two sides
Needle bearing connection in notch.Sliding block is moved in the notch of guide groove two sides by the bearing support on positioning pin.Sliding block
It is connected with axial force sensor by stretching screw, sliding block adjusts the position in guide groove by stretching screw.Tested bolt is logical
Sleeve is crossed to connect with torque sensor.
The sliding block for connecting tested bolt and slider guide slot are designed as circle, while sliding block and guide groove by the utility model
It is connected using needle bearing, changes the face contact of sliding block and guide groove, sliding block is pulled by needle bearing when bolt strained, is subtracted
Lack the frictional force of sliding block and guide groove, reduces influence of the frictional force to the measured value of axle power, to improve torque coefficient result
Accuracy.
The utility model has the advantages that: cooperated using round axle power test slider guide groove and cylindrical body sliding block, reduces and slide
The friction of block and slider guide groove sidewall, and Influence from Eccentric caused by process and assemble error is reduced, improve the standard of axle power measurement
True property.
