Abstract

The utility model provides a vernier clearance gage used for measuring the clearance. The utility model comprises a main scale with a slope, a scale frame, a vernier, measuring jaws and a fastening screw; the main scale is provided with the reticle and the digital, the scale frame is sheathed on the main scale, the vernier is fastened to the scale frame, the measuring jaws extend from the end of the scale frame, and the scale frame is locked on the main scale via the fastening screw arranged on the scale frame. The device solves the problem of the existing large measuring error in the measurement of the clearance via the measuring method and the equipment. The utility model which can be widely used for measuring various clearances has the advantages of convenient operation and wide measuring range. The reading precision can attain form 0.01 to 0.005.

Description

Vernier clearance gage
The utility model relates to surveying instrument.
In the process of the main equipment of electromechanical industries assembling, there are many gaps to need to measure, present widely used method is to utilize the conical surface two limits as measurement face, one side on the conical surface engraves reading groove and numeral, during measurement, cone is filled in the gap, make two limits on the conical surface near two ribs in gap, can read the numerical value of measurement clearance from the groove, the shortcoming of this kind method is that measured value is accurate inadequately, other has a key name to be called " feeler gauge " Russian Patent SU1322074 number to disclose a kind of instrument that utilizes conical surface measurement clearance, if the end face of this instrument gap two articles when measuring between the two articles not at grade then just the gap width of measuring has very big error.
Task of the present utility model is: design a kind of Vernier clearance gage that utilizes the convenient accurate measurement clearance in inclined-plane.
Task of the present utility model realizes as follows: Vernier clearance gage comprises a main scale that has the inclined-plane, groove and numeral are arranged on it, be enclosed within a chi frame is arranged on the main scale, a vernier scale is fastened on the chi frame, measuring claw is stretched out in chi frame end, and the chi frame is provided with the holding screw that the chi frame can be locked on the main scale.
The principle of work of this device is: the inclined-plane of the main scale of Vernier clearance gage is the slope of 1:20, the groove of accurate calibration is carved with on the main scale surface in corresponding position, be to utilize the reference field of main scale parallel with a face in gap and overlap and utilize the inclined-plane just to measure to contact in measuring process with the end face of another face in gap, one-tenth-value thickness 1/10 herein is exactly the measured gap width of expression, and the corresponding groove of everywhere one-tenth-value thickness 1/10 and everywhere is corresponding one by one on the main scale, so the numerical value of measurement clearance is just read the numerical value of corresponding groove, the effect of chi frame is the position that indicates that groove of the reading of wanting, and the effect of Vernier clearance gage is a decimal of reading the integer back.
The utility model is owing to utilize vernier to cooperate the inclined-plane to carry out clearance measurement, has therefore that measurement range is big, measuring accuracy is high, and is easy to use, and can direct reading advantage.
Fig. 1 is the utility model front view;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the utility model instrumentation plan;
Fig. 4 is the another kind of metering system synoptic diagram of the utility model;
A most preferred embodiment of the present utility model, as figure, Vernier clearance gage comprises main scale 1, the groove that accurate calibration is arranged on its hypotenuse, be enclosed within have on the main scale chi frame 2 can be neatly, on main scale, move reposefully, and indicate the position of the reading groove of wanting, vernier scale 3 is fixed on that its reading is accurate to 0.01~0.005mm on the chi frame 2, the upper topside of chi frame has a threaded hole, and a holding screw 4 is screwed into any position that wherein chi frame 2 can be locked at main scale 1, and 5 is that measurement face, 6 is a reference field.

Claims (2)

1, a kind of Vernier clearance gage comprises a main scale that has hypotenuse, and groove and numeral are arranged on the hypotenuse, of the present utility model being characterised in that: being enclosed within has a chi frame on the main scale, a vernier scale is fastened on the chi frame, and measuring claw is stretched out in chi frame end, is provided with locking device between chi frame and the main scale.
2, Vernier clearance gage as claimed in claim 1 is characterized in that: the locking device between said chi frame and the main scale is to have threaded hole on the chi frame, and a holding screw is arranged on it.
