Technical field
The utility model relates to a kind of torsion modulus measurement mechanism, especially relates to a kind of cam method torsion indicator.
Technical background
In university education, reverse and also there is no corresponding supporting experimental apparatus as the mechanics of materials and engineering mechanics important component part.And beginner only depends on theory study to be difficult to clearly to understand the concepts such as torsions, torsion angle, more difficult by knowledge for putting into practice.How to apply short and sweet torsion angle experimental apparatus aided education and seem very necessary.
Existing torsion phenomenon observation instrument on the market at present, as microcomputer controlled torque tester etc., complex structure and cost are high, most ofly need special electrical module, are difficult for portably using, and are not suitable for teaching process.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, cheap and cam method torsion indicator that measuring accuracy is high.
The utility model is provided with support, gear pair, loading cantilever, cam and dial gauge;
Support is provided with bottom bar, left vertical rod, right vertical rod and axle clamp head; Left side and the right side of bottom bar is located at respectively in left vertical rod and right vertical rod, left vertical rod lower end and right vertical rod lower end and bottom bar sliding connection, and by regulating locking member to be locked, left vertical rod and right vertical rod top are arranged with upper and lower 2 pairs of horizontal shaft holes, 2 pairs of horizontal shaft holes are equipped with bearing, and bearing is for being rotatably assorted upper torsion shaft to be measured and lower torsion shaft and left vertical rod and right vertical rod; Set 2 the horizontal shaft hole places up and down of right vertical rod are equipped with axle clamp head, the set lower horizontal shaft hole place of left vertical rod is also provided with axle clamp head, gear pair is provided with upper and lower 2 gears, and the set axle clamp head of right vertical rod is used for upper torsion shaft right-hand member to be measured is connected respectively with 2 gears up and down of gear pair with lower torsion shaft right-hand member; Load cantilever and be installed on the set lower horizontal shaft hole place of left vertical rod, be rotatably assorted, and be connected with lower torsion shaft to be measured with this lower horizontal shaft hole, loading cantilever one end has loading disc; Cam is connected with lower torsion shaft left end to be measured by the set axle clamp head of left vertical rod; Dial gauge is arranged in left vertical rod, and is positioned at cam below, and nib and the cam curved surface of dial gauge touch.
Described left vertical rod, right vertical rod are preferably the vertical rod of L font.
Described cam is preferably spiral of Archimedes cam.
Described adjusting locking member is preferably jackscrew.
Compared with the prior art, principle of work of the present utility model and advantage are as follows:
During use, upper and lower 2 torsion shaft two ends to be measured are arranged on respectively on the symmetrical set 2 pairs of horizontal shaft holes up and down in left vertical rod and right vertical rod top, the right-hand member of upper and lower 2 torsion shafts is all by axle clamp head clamping, the left end of upper torsion shaft is fixed by fixture, in the loading disc that loads cantilever, placed counterweight counterweight.Like this, under the Action of Gravity Field of counterweight weight, loading cantilever can rotate, and drives lower torsion shaft and makes upper torsion shaft also reverse (because lower torsion shaft left end is free end, and upper torsion shaft left end is stiff end, therefore can form torsion) through gear pair transmission.Meanwhile, cam, also along with rotation, like this, accurately measures the variable quantity of cam rise, and then draws torsion angle by dial gauge.
The material of described torsion shaft to be measured is realized the easily variable of lower end shaft diameter to be measured by changing the axle clamp head matching with different cross section situation and axis hole, quantitative contrast different materials, different-diameter, varying cross-section (for example square) material is the multiple relation of torsion angle under moment loading outside.In addition, by jackscrew, regulate, can make the spacing between left vertical rod and right vertical rod change, torsion shaft test to be measured that so also can suitable different length, optimized the function of the linear relationship of checking windup-degree and length of material, thereby can further improve teaching effectiveness, gear pair is realized the transmission of moment, make the stiff end (axle clamp head is not used but direct locked position in upper left) of material and the same side that free end is positioned at device, in the situation that participate in the axial length to be measured of test constant, by the contraction in length of device, be original 1/2nd, improve stability simultaneously, save material and space.Cam rotation is converted to the linear change of cam rise by small torsion angle, then with dial gauge, accurately measures the change amount △ r of cam rise.Thereby go out windup-degree by cam curve formula to calculating.On the one hand improve measuring accuracy, reduce measuring error, practicality, reliability are higher, in needing the Machine Design manufacture field of precision measurement, have wide market potential.Make on the other hand processing comparatively easy, design processing cost is lower, suitable to teaching aid and experimental apparatus.
