Abstract
A kind of detection cross slot bolt, screw twisting torque test tool, including pedestal, support rod, connecting rod, bearing, tool connection sleeve, dynamometer spring and tighten nut；The support rod bottom end is movably set in pedestal；Nut and connecting rod are tightened by upper have certainly in the support rod；Dynamometer spring is equipped between nut and connecting rod tightening；One end is equipped with bearing in connecting rod, and the interior tool that is equipped with connects sleeve.Bearing in the utility model substantially reduces the frictional force of tool connection sleeve and connecting rod, reduces influence of the twisting torque to test result during test;Carrying out test by the utility model, to can guarantee that test process is applied to the axial force on test instrument constant, and it can accurately measure the size of the axial force of application, related personnel's regular check sample is only needed to grind situation using the utility model, to greatly save the sample preparation time of staff.
Description
Technical field
The utility model relates to a kind of detection cross slot bolts, the test tool of the twisting torque of screw, belong to mechanical system
Make field.
Background technique
For cross slot bolt or screw class product, not to the axis of application in original test breakdown torque test method
It is required to masterpiece, splits test products during the test in order to twist into two parts, often loaded a biggish axial force and do not allow test
Tool, which exits cross recess while applying torque, makes its destruction, and breakdown torque is able to satisfy performance requirement.This kind of product is mounted in spy
When different place, it is desirable that determine torque installation, find to be unable to reach defined mounting torque using tool during the installation process, consult phase
It closes technical conditions and finds that the mounting torque is much smaller than the destrabilizing moment of product, finally found that the axial force applied during the test
The axial force applied when long-range small installation.Now claiming to this kind of product during the test can to test instrument application one
Force value is controlled, twisting torque cannot be less than certain value, not require to carry out breakdown torque test to test products.
Existing test instrument, which determines torque wrench, can accurately measure the twisting torque of application, but be applied to the axial direction on tool
Power size can not detect.
Utility model content
The utility model is the undetectable technology of axial force size in order to solve to be applied in the prior art on tool
Problem.
In order to solve the above-mentioned technical problem, the utility model uses following technical proposal:
A kind of detection cross slot bolt, screw twisting torque test tool, including pedestal, support rod, connecting rod, axis
It holds, tool connects sleeve, dynamometer spring and tightens nut；
The support rod bottom end is movably set in pedestal；Nut and connection are tightened by upper have certainly in the support rod
Bar；Dynamometer spring is equipped between nut and connecting rod tightening；One end is equipped with bearing in connecting rod, and the interior tool that is equipped with connects
Sleeve.
By adopting the above technical scheme the utility model has the advantages that
1, the bearing in the utility model substantially reduces the frictional force of tool connection sleeve and connecting rod, and reduction was tested
Influence of the twisting torque to test result in journey.
2, test is carried out by the utility model to can guarantee that test process is applied to the axial force on test instrument constant, and
The size of the axial force of application can accurately be measured.
3, related personnel's regular check sample is only needed to grind situation using the utility model, to greatly save work people
The sample preparation time of member.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
In figure: 1- pedestal, 2- support rod, 3- connecting rod, 4- bearing, 5- tool connection sleeve, 6- dynamometer spring, 7- are tightened
Nut.
Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing, but not the utility model institute should not be interpreted as with regard to this
The range for stating theme is only limitted to embodiment below, all according to this when not departing from the above-mentioned technical idea of the utility model
Various modifications, replacement and the change that field ordinary technical knowledge and customary means are made, are included in the scope of the utility model
It is interior.As shown in Figure 1, a kind of test tool of the twisting torque of detection cross slot bolt, screw, including pedestal 1, support rod 2, company
Extension bar 3, bearing 4, tool connect sleeve 5, dynamometer spring 6 and tighten nut 7；2 bottom end of support rod is movably set in pedestal 1
It is interior；Nut 7 and connecting rod 3 are tightened by upper have certainly in the support rod 2；It is surveyed tightening to be equipped between nut 7 and connecting rod 3
Power spring 6；One end is equipped with bearing 4 in connecting rod 3, and the interior tool that is equipped with connects sleeve 5.
First support rod 2 is screwed on pedestal 1 using preceding, and by connecting rod 3 in support rod 2, and loads onto dynamometry bullet
Spring 6 and tighten nut 7；Torque wrench is mounted on tool connection 5 upper end of sleeve, and is loaded onto tool connection 5 lower end of sleeve
Cross recess twisting tool.
Test screw is mounted in blind threaded tooling as required when test, and the screw thread tooling for installing screw is consolidated
Determine under twisting tool, and adjusts position and tool is completely inserted into the cross recess of screw；Branch is tightened according to test requirements document
The adjustment dynamometer spring 6 of nut 7 of tightening held on bar 2 uses the corresponding axial compressive force of generation.
The test axial force of the utility model is provided by dynamometer spring 6, and according to F=KL, (K is elasticity system element, L is bullet
The decrement of spring), the decrement by controlling dynamometer spring 6 can control the axial force of application.
