A measuring method of the piston center distance measuring tool comprises the following steps that: the distance from the fixed plate to the axis of the rotating shaft is determined, the matching between the rotating shaft and the piston groove is utilized, the coincidence of the center of the piston groove and the axis of the rotating shaft is determined, then, the distance from the top surface of a piston to the fixed plate is measured by the dial indicator, subtraction is carried out between the two values, and the center distance of the piston can be obtained.
Description
Technical field
The present invention relates to the measurement detection range of compressor of air conditioner piston, especially a kind of piston center distance measurement instrument.
Background technology
Piston centre distance L, as shown in Figure 1, be the distance of piston groove center, at present the interior measurement more complicated of industry to piston centre distance to piston-top surface, need to measure nearest distance of piston groove and piston-top surface and distance farthest, addition is again except that in two distances that obtain centre distance then.This measuring method relative complex needs by twice measurement, and each the measurement is difficult to accurately find measurement point, cause measuring error bigger, cause the accumulative total of error during simultaneously by subsequent calculations, so that the centre distance of measuring existence is difficult to obtain accurate data than mistake.
Summary of the invention
The objective of the invention is provides a kind of measurement simple for the deficiency that solves above-mentioned technology, the piston center distance measurement instrument that measuring accuracy is high.
In order to achieve the above object, the piston center distance measurement instrument that the present invention is designed, it mainly comprises measuring, measuring is a V-type groove structure, be provided with fixed head in measuring one side, other end level at measuring is provided with turning axle, the axle center of turning axle is vertical with the V-type groove center line of measuring, be provided with the recessed structure that cooperates with piston groove on turning axle, recessed structure is in V-type groove center line place, and recessed structure is with after piston cooperates, piston groove center and axis coinciding, two symmetrical planes are processed at recessed structure place on turning axle, and the distance between two symmetrical planes is provided with through hole less than the distance of piston groove opening part on fixed head, be provided with lining in the through hole, the lining center line is parallel with the center line of V-type groove, and lining center line and axle center be in the same plane, is provided with clock gauge in lining.This design feature is: clear and definite fixed head is to the distance in the axle center of turning axle, utilize cooperating of turning axle and piston groove, determine the center of piston groove and the axis coinciding of turning axle, use clock gauge to measure piston-top surface then to the distance between the fixed head, at last fixed head to the distance in the axle center of turning axle is deducted the distance of fixed head to piston-top surface, can obtain piston centre distance, it is more accurate to measure.
Accurately simple more for the measurement of piston centre distance, guarantee that the center line of piston is parallel with the center line of clock gauge, adopt when piston cooperates with turning axle, the V-type groove is consistent to the distance at lining center with the V-type groove to the distance at piston center.
As optimization, directly over lining on the fixed head, be provided with and hold out against screw, can avoid the trickle displacement of clock gauge generation in measuring process, thereby influence measuring accuracy.
For convenience in measuring process to the rotation of turning axle, be provided with handle in a side of turning axle.
The resulting piston center distance measurement of the present invention instrument; utilize turning axle to cooperate with piston groove; the axle center of determining turning axle overlaps with the center of piston groove; the axial line of the center line of the clock gauge of She Zhiing and turning axle is vertical and be in same plane simultaneously; simultaneously the concrete V-type groove of utilization guarantees that piston is with after turning axle cooperates; piston center line and clock gauge central lines make measurement more accurate.The method of its measurement is: clear and definite fixed head is to the distance in the axle center of turning axle, utilize cooperating of turning axle and piston groove, determine the center of piston groove and the axis coinciding of turning axle, use clock gauge to measure piston-top surface then to the distance between the fixed head, at last fixed head to the distance in the axle center of turning axle is deducted the distance of fixed head to piston-top surface, can obtain piston centre distance, measure simpler, and measuring accuracy height.In addition, directly over lining, be provided with and hold out against screw, can avoid the trickle displacement of clock gauge generation in measuring process, thereby influence measuring accuracy.
