Abstract
The invention relates to the field of tools, and in particular relates to a cam detection tool which comprises a bottom plate, wherein a rotatable shaft is arranged on the bottom plate; an adjusting block which is parallel to the shaft is further arranged on the bottom plate; a vernier of a caliper is fixed on the adjusting block; a groove is formed in the bottom plate; the adjusting block can move leftwards and rightwards in the groove; a spring is arranged between two clamping claws of the sliding caliper. When the cam detection tool is used for detection, a cam is mounted on the shaft, a zero graduation line of the cam contacts the front end of the caliper, the caliper tightly clamps the curved surface of the cam under the action of the elastic force of the spring, the vernier of the caliper is fixed on the adjusting block, the adjusting block slides inside the groove, and thus cams of different specifications can be measured. A number which is based on a base circle is read from the caliper, when the came rotates for a certain angle, another number is obtained, the difference between the two numbers is just the elevation of the cam at the point, and the precision of the cam can be judged by measuring different key points according to design requirements.
Description
Technical field
The present invention relates to frock field, particularly a kind of Cam Detection frock.
Background technology
Cam is a component with curved profile or groove.In cam is produced and is detected, the detection of the contour curve of cam is the mode adopting template contrast, accuracy of detection is not high, in the use procedure of cam, can produce wearing and tearing, wear extent is not easily directly measured and is obtained, and can affect the quality of production of subsequent product, need to design a kind of structure simple, the Cam Detection frock that convenient operation, measuring accuracy are high, measurement range is wide.
Summary of the invention
The object of this invention is to provide a kind of structure simple, the Cam Detection frock that convenient operation, measuring accuracy are high, measurement range is wide.
Technical scheme of the present invention is as follows: a kind of Cam Detection frock, comprise base plate, base plate is provided with rotating axle, base plate is also provided with the regulating block parallel with axle, regulating block is fixed with the secondary chi of slide calliper rule, base plate is provided with groove, and regulating block moves left and right in groove, is provided with spring between two claws of slide calipers.Regulating block side is provided with lock-screw.
During detection, cam is arranged on axle, the zero graduation line of cam is contacted with the front end of slide calliper rule, slide calliper rule clamp with cam curved surface under the effect of the elastic force of spring, the secondary chi of slide calliper rule is fixed on regulating block, and regulating block slides in groove, can measure the cam of different size.Read from slide calliper rule the numerical value that one take basic circle as benchmark, when cam turn one determine angle time, another numerical value can be obtained, difference between these two numerical value is exactly the lift of this some place cam, according to designing requirement, each key point is measured, just can judge the precision of cam.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention will be further described:
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of Cam Detection frock of the present invention, comprise a base plate 1, base plate is provided with rotating axle 2, base plate 1 is also provided with the regulating block 6 parallel with axle 1, regulating block 6 is fixed with the secondary chi 43 of slide calliper rule 4, base plate 1 is provided with groove 8, regulating block 6 moves left and right in groove 8, is provided with spring 5 between the first claw 41 of slide calliper rule and the second claw 42.Regulating block 6 side is provided with lock-screw 7.
During detection, cam is arranged on axle, the zero graduation line of cam is contacted with the front end of slide calliper rule 4, slide calliper rule 4 clamp with cam curved surface under the effect of the elastic force of spring 5, the secondary chi 43 of slide calliper rule is fixed on regulating block, and regulating block 6 slides in groove 8, can measure the cam of different size.Read from slide calliper rule the numerical value that one take basic circle as benchmark, when cam turn one determine angle time, another numerical value can be obtained, difference between these two numerical value is exactly the lift of this some place cam, according to designing requirement, each key point is measured, just can judge the precision of cam.
