Abstract
The utility model discloses a diaphragm spring taper angle measurer, which can increase measurement precision and is convenient in use. The diaphragm spring taper angle measurer comprises a flat plate and a dial indicator component, the flat plate is provided with a stop scale and a guide scale arranged perpendicular to the stop scale, the flat plate is further provided with a movable standard block, the dial indicator component comprises a dial base, a telescopic arm is arranged on the dial base, and the front end of the telescopic arm is provided with a dial indicator.
Description
Technical field
The utility model relates to a kind of measurer, specifically is the measurer of diaphragm spring cone angle in the measured automobiles clutch coupling.
Background technology
Existing what be used for the diaphragm spring measurement of angle is the etalon universal protractor that measurer factory produces, and its deficiency is: when one, universal protractor was measured first tapering, the line length of film spring first tapering was too short, and second tapering can cause interference to measurement; Two, the resolution of universal protractor be 2 ', measuring accuracy is not high.Three, to survey second cone angle must be benchmark with first cone angle to universal protractor, and can't directly draw relative datum Plane Angle value.Four, be reference measurement second awl with first tapering, second tapering is short, and diaphragm spring separates finger tip has the radian of projection to interfere and can't measure.
The utility model content
The utility model to be exactly to measure the drawback that exists with regard to the technical matters that solves at universal protractor, provide a kind of and can improve measuring accuracy and the convenient cone angle measuring instrument of diaphragm spring that uses.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: cone angle measuring instrument of diaphragm spring, it is characterized in that: comprise flat board and dial gauge assembly, flat board is provided with the retaining chi and reaches and the vertically disposed jig of retaining chi, also be provided with the calibrated bolck of an activity on the flat board, described dial gauge assembly comprises the gauge stand that is used for fixing usefulness, and gauge stand is provided with telescopic arm, and the telescopic arm front end is provided with dial gauge.
Described telescopic arm comprise switching on gauge stand the lifting pivoted arm and the switching at the horizontal pivoted arm that rises valency pivoted arm end, dial gauge is connected the end of horizontal pivoted arm.
Preferably, described calibrated bolck is the prolate square body, and width is pressed the established standards design.
Preferably, described gauge stand is the magnet gauge stand.
Also post the conversion table of a cone angle and height on the described flat board, promptly according under the constant situation of calibrated bolck width, the differing heights data of surveying can be found the cone angle value of correspondence very soon.
The utility model adopts technique scheme, calibrated bolck is placed in the middle of diaphragm spring and the retaining chi before measuring, dial gauge is beaten on institute's survey tapering, take out calibrated bolck, push keep off diaphragm spring to chi, the diaphragm spring forward pitch is from being B, and the dial gauge pointer records height change data A, utilizes arc tangent trigonometric function α=arctan (A/B) to try to achieve the cone angle value.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of the utility model cone angle measuring instrument of diaphragm spring;
Fig. 2 is for measuring the initial structure synoptic diagram;
Fig. 3 finishes structural representation for measuring.
Embodiment
As shown in Figure 1, be the utility model cone angle measuring instrument of diaphragm spring, comprise flat board 1 and dial gauge assembly, dull and stereotyped 1 is provided with retaining chi 2 reaches and the vertically disposed jig 3 of retaining chi, also be provided with the calibrated bolck 4 of an activity on the flat board, described calibrated bolck is the prolate square body, and width is pressed the established standards design.Described dial gauge assembly comprises dial gauge 5 and is used for fixing the gauge stand 6 of usefulness, and gauge stand is provided with telescopic arm, described telescopic arm comprise switching on gauge stand lifting pivoted arm 7 and switching at the horizontal pivoted arm 8 that rises valency pivoted arm end, dial gauge is connected the end of horizontal pivoted arm.Stating gauge stand in the utility model is the magnet gauge stand, is convenient to be fixed on the extraneous metal pedestal.Also post the conversion table 9 of a cone angle and height on the described flat board, promptly according under the constant situation of calibrated bolck width, the differing heights data of surveying can be found the cone angle value of correspondence very soon.Calibrated bolck is placed in the middle of diaphragm spring 01 and the retaining chi 2 before measuring, dial gauge is beaten on institute's survey tapering (as Fig. 2), take out calibrated bolck, push keep off diaphragm spring to chi, the diaphragm spring forward pitch is from being B, the dial gauge pointer records height change data A (as Fig. 3), utilizes arc tangent trigonometric function α=arctan (A/B) to try to achieve the cone angle value.The utility model can be used for the measurement of Belleville Springs of Tractor Clutch cone angle equally.
