Compared with the prior art, the device for detecting the characteristic moment value of the torsional spring has the advantages of compact structure, is simple and convenient to use, and can be used for accurately detecting to obtain the characteristic moment value of the torsional spring so as to provide a basis for the quality control over the torsional spring.
Description
Technical field
The invention belongs to the testing tool technical field, be specifically related to a kind of pick-up unit of torsion spring characteristic moment values.
Background technology:
The requirement of torsion spring characterisitic parameter is its important techniques desired value at the moment values M that the twisting angle [alpha] of stipulating can reach.The accurate tolerance of this parameter directly influences the result of use of torsion spring.Present common use client does not have accurately to detect the method and apparatus of this parameter, relies on feel or direct assembling back affirmation result of use to judge whether torsion spring meets the demands substantially.The deficiency of this method is the accurate concrete numerical value of critical parameter, to the control that has the strict service condition of desired value to ensure the quality of products.
Summary of the invention
Above-mentioned defective for the solution prior art exists the object of the present invention is to provide a kind of compact conformation, and is easy to use, conveniently detects the pick-up unit of torsion spring characteristic moment values.
For achieving the above object, the technical solution used in the present invention: the pick-up unit of this torsion spring characteristic moment values, it is characterized in that: have body, rotation axis is arranged in the body inner via hole by bearing, one end of rotation axis is fixed with the centralized positioning pin, the centralized positioning guide is contained in the center pit of fixed head, rotation axis processes corresponding pickup groove with fixed head according to the angle position that torsion spring stretches out the limit, be used for placing the test torsion spring, rotation axis is provided with annular groove, bottom portion of groove is fixed with stay cord, body is provided with fixed pull ring, the fixedly connected index dial that is useful on sign torsion spring rotational angle of the other end of rotation axis, fixed head and body adopt hinge engaging structure for convenience detach.
Described index dial is provided with draw-in groove, and the dial torque wrench interface rings is connected in the draw-in groove, and the dial torque wrench interface rings is provided with the bayonet socket that cooperates with dial torque wrench.
Described hinge engaging structure have the hinge be pulled on the body standing screw and with the screw rod nut engaged, fixed head is provided with the U-shaped draw-in groove that standing screw snaps in, open washer is connected on the standing screw.
Adopt the beneficial effect of technique scheme: the pick-up unit of this torsion spring characteristic moment values and spring tension and compression machine or dial torque wrench coupling are used.The rotation axis of this pick-up unit can rotate with respect to body and fixed head, for reducing test error, adopts rolling bearing between rotation axis and the body, is the loading and unloading of convenient test torsion spring, and fixed head and body adopt hinge engaging structure for convenience detach.Rotation axis processes corresponding pickup groove with fixed head according to the angle position that torsion spring stretches out the limit, is used for placing the test torsion spring.The design index dial of fixedlying connected with rotation axis is used to identify the torsion spring rotational angle.1. when using with spring tension and compression machine coupling, be to twine some circle stay cords on the axle journal of d at rotating collar connected in star diameter, the fixed pull ring on the body and the stay cord other end are linked on the hook of spring tension and compression machine, pull the spanner handle of spring tension and compression machine, draw value of thrust F. on the stay cord according to rotational angle α, then drawing the characteristic torque value of torsion spring when rotational angle α is M=F * d/2.2. when using with the dial torque wrench coupling, the interior realization of draw-in groove that the dial torque wrench interface rings directly is connected to index dial connects.The moment values that dial torque wrench when utilizing dial torque wrench to pull index dial rotational angle α shows is characteristic torque value M.Compared with prior art, this pick-up unit compact conformation, easy to use, convenient, detect torsion spring characteristic moment values accurately, for the quality control of torsion spring provides foundation.
