Description
Technical field
The present invention relates to the measurement detection range of compressor of air conditioner piston, especially a kind of centre is apart from survey instrument.
Background technology
Centre is apart from L; As shown in Figure 1, be the distance of piston groove center to piston-top surface, at present in the industry to the measurement more complicated of centre distance; Need to measure nearest distance of piston groove and piston-top surface and distance farthest, then addition again except that in two obtain centre distance distance.This measuring method relative complex needs through 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 through 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 to provide for the deficiency that solves above-mentioned technology a kind of measurement simple, the high centre of measuring accuracy is apart from survey instrument.
In order to achieve the above object, the centre that the present invention designed is apart from survey instrument, and it mainly comprises measuring; Measuring is a V-type groove structure, is provided with fixed head in measuring one side, is provided with turning axle in the other end level of measuring; The axle center of turning axle is vertical with the V-type groove center line of measuring, on turning axle, is provided with the recessed structure that cooperates with piston groove, and recessed structure is in V-type groove center line place; And recessed structure is with after piston cooperates, piston groove center and axis coinciding, and two symmetrical planes are processed at the recessed structure place on turning axle; 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, in lining, is provided with clock gauge.This design feature is: the distance in the axle center of clear and definite fixed head to turning axle; Utilize cooperating of turning axle and piston groove; Confirm the center of piston groove and the axis coinciding of turning axle, use clock gauge to measure the distance between piston-top surface to the fixed head then, deduct the distance in the axle center of fixed head to turning axle the distance of fixed head to piston-top surface at last; Can obtain the centre distance, it is more accurate to measure.
Accurately simple more for the measurement of centre distance, guarantee that the center line of piston is parallel with the center line of clock gauge, when being employed in piston and cooperating with turning axle, the distance of V-type groove to centre and V-type groove to lining center apart from consistent.
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 ease in measuring process to the rotation of turning axle, be provided with handle in a side of turning axle.
The resulting centre of the present invention is apart from survey instrument; Utilize turning axle to cooperate with piston groove; The axle center of confirming turning axle overlaps with the center of piston groove, and the center line of the clock gauge that is provided with simultaneously is vertical with the axial line of turning axle and be in same plane, and the concrete V-type groove of while utilization guarantees that piston is with after turning axle cooperates; Centre line and clock gauge central lines make measurement more accurate.The method of its measurement is: the distance in the axle center of clear and definite fixed head to turning axle; Utilize cooperating of turning axle and piston groove, confirm the center of piston groove and the axis coinciding of turning axle, use clock gauge to measure the distance between piston-top surface to the fixed head then; Deduct the distance in the axle center of fixed head to turning axle the distance of fixed head to piston-top surface at last; Can obtain the centre distance, measure simplyr, and measuring accuracy is high.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.
