There is the torque force testing instrument that function is eliminated in vibrations
Technical field
The present invention relates to a kind of torsion checking device, be specifically related to a kind of torque force testing instrument with vibrations elimination function.
Background technology
This series products of notebook computer in use, rotating shaft is the parts of easy loss, qualified rotating shaft must can tolerate the folding of certain number of times, qualified in order to ensure the product come into operation (especially rotating axis component), torsional test must be carried out before it dispatches from the factory, namely by the actual use procedure of equipment simulating, countershaft applies torsion, and whether the folding carrying out certain number of times continuously tolerates to detect rotating shaft.Existing tester, due to self unsurmountable defect, applies also there are vibrations in the process of torsion at countershaft, cause the resultant error of test larger, but also greatly have impact on the serviceable life of sensor, along with the raising to test result accuracy requirement, this problems demand solves.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of torque force testing instrument, eliminating the vibrations in the torque force testing instrument course of work and the impact of shake on test result, improve the accuracy of test result.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
There is the torque force testing instrument that function is eliminated in vibrations, comprising: board, electrical control mechanism, torsion testing mechanism, vibrations eliminating machine, the platform placing product and elevating mechanism, described electrical control mechanism comprises motor, controller and operation screen, described torsion testing mechanism comprises torsion torque sensor, by motor-driven rocking arm, be fixed on one end and be provided with the cross bar of some fixtures, described vibrations eliminating machine comprises: the contiguous block be connected with the output shaft of motor, described contiguous block passes rocking arm and is set in a bearing, described elevating mechanism comprises: for the first back-up block of carrying platform, line rail, described first back-up block and line rail are slidably connected and realize being fixed to one another by a latch mechanism, described line rail and bearing are arranged in a guard shield.
Aforementioned motor and torsion testing mechanism are arranged in the first housing, and the first housing is installed on board.
Aforementioned board is also provided with the second housing, and described controller is placed in the second housing, and described elevating mechanism also comprises: the second back-up block being installed on the slide rail of the second housing side, being slidably connected with slide rail.
Aforementioned line rail and slide rail are equipped with rule.
The bottom of aforementioned board is provided with universal wheel.
Aforementioned locking mechanism is screw or the eccentric locking pin with operating grip.
Usefulness of the present invention is: during torque force testing instrument work of the present invention, first by lifting platform to suitable position time, fixed by the position of latch mechanism by platform, after electric motor starting, rocking arm will drive by motor and rotate, because platform is locked so platform can not rock, simultaneously due to the existence of bearing, eliminate issuable vibrations in the course of work, measure the numerical value come more accurate, test curve is more level and smooth.

Embodiment
Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the present invention.
See Fig. 1, of the present invention have the torque force testing instrument that function is eliminated in vibrations, comprising: board 1, electrical control mechanism, torsion testing mechanism, vibrations eliminating machine, the platform 2 placing product and elevating mechanism.Wherein, electrical control mechanism comprises motor, controller and operation screen 3, torsion testing mechanism comprises torsion torque sensor, by motor-driven Rocker arm 4, be fixed on Rocker arm 4 one end and be provided with the cross bar 5 of some fixtures 6, vibrations eliminating machine comprises: the contiguous block 7 be connected with the output shaft of motor, contiguous block 7 passes Rocker arm 4 and is set in a bearing 8, elevating mechanism comprises: for the first back-up block 9 of carrying platform 2, line rail 10, first back-up block 9 is slidably connected with line rail 10 and realizes being fixed to one another by a latch mechanism 12, line rail 10 and bearing 8 are all arranged in a guard shield 11.Particularly, latch mechanism 12 is screw or the eccentric locking pin with operating grip.
Contiguous block 7 is connected to the output shaft of motor and passes Rocker arm 4; when motor rotation; Rocker arm 4 will follow contiguous block 7 to rotate; and bearing 8 is set in the end of contiguous block 7; so; the inner ring of bearing 8 rotates and outer ring is motionless, again because bearing 8 is arranged in guard shield 11, so guarantee that guard shield 11 can not rotate and shake.When platform 2 needs lifting, first unclamp latch mechanism 12, when arriving target location, latch mechanism 12 is locked, like this, Rocker arm 4 is when rotating, and platform 2 would not rock or shake, the numerical value that torsion torque sensor is measured will be more accurate, and the curve of test becomes more level and smooth.
In order to make equipment overall structure compact, board 1 has been installed the first housing 13 and the second housing 14, and motor and torsion testing mechanism are arranged in the first housing 13, and controller is placed in the second housing 14.
In order to make platform 2 more steadily shockproof, elevating mechanism also comprises: the second back-up block 15 being installed on the slide rail of the second housing 14 side, being slidably connected with slide rail.So, platform 2 reliably supports from the two ends of platform 2 by the first back-up block 9 and the second back-up block 15, guarantees further in test process without rocking and shaking.
Preferably, line rail 10 and slide rail are equipped with rule and are positioned at sustained height to make the first back-up block 9 and the second back-up block 15.
Further, the bottom of board 1 is provided with universal wheel 16.
More than show and describe ultimate principle of the present invention, principal character and advantage.The technician of the industry should understand, and above-described embodiment does not limit the present invention in any form, the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection scope of the present invention.
