Abstract
The utility model provides an auxiliary round bar with light holes for measuring positions of surface holes of a valve sleeve part and relates to the technical field of a measuring auxiliary device of a universal tool-measuring microscope. Through replacement of an axis of the auxiliary round bar, the problem that the requirement for measuring a datum line of the valve sleeve to be measured is hard to meet due to limit of chamfers of orifices on two ends of the measured valve sleeve is solved.
Description
Technical field
The present invention relates to the servicing unit technical field that universal tool-measuring microscope is measured.
Background technology
Rudder face position on the aviation aircraft is the critical component of decision aircraft flight state, and rudder face position on the controlling aircraft and kinematic accuracy servo actuator commonly used.One of vital part in the servo actuator is a valve pocket, and its structure is as shown in Figure 1, is a small-sized hollow cylinder, is with several rectangular recess on the hollow cylinder surface, in the bottom of rectangular recess along cylindrical surface four square holes that equally spaced distribute; Because this valve pocket is precision component, the depth of parallelism of square hole in the coplane degree of four square holes in the same groove and the different groove is all had high requirements.Because tiny vernier caliper and the three coordinate measuring machine of can't using of square hole measure, the surveying work that can only be correlated with universal tool-measuring microscope.Because the restriction of aperture, valve pocket two ends chamfering directly with the cone centre clamping valve pocket at two ends on the universal tool-measuring microscope, is difficult to satisfy the requirement of treating side valve cover datum line.
Summary of the invention
The objective of the invention is: for satisfy universal tool-measuring microscope treat side valve cover detect in the requirement of datum line, the special auxiliary pole that proposes a kind of valve bush part surface holes position measurement with light hole.
Technical scheme of the present invention is: through the substitution effect of auxiliary pole axis, solve because the restriction of aperture, tested valve pocket two ends chamfering is difficult to satisfy the problem of treating the requirement of side valve cover datum line.The structure of auxiliary pole is as shown in Figure 2, and pole is a solid bar, has taper pilot hole 1 in the both ends of the surface axial location of solid bar, and the middle part of solid pole is the support portion 2 that has the fixing valve pocket to be measured of certain taper, and the both sides of support portion 2 are transition part 3; Jam-pack was fixing used when the tapering of support portion 2 was used for quilt cover reception side valve cover, and the position corresponding with housing square edged orifice to be measured has the through hole 4 greater than tested square hole on the support portion 2, the printing opacity when being suitable for testing.
The present invention has the following advantages: the application of auxiliary pole of the present invention, and satisfy universal tool-measuring microscope and treated the requirement that side valve overlaps datum line in the detection.

Fig. 2 is a pole front view of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
In valve pocket production in certain type servo actuator and the measurement; Because the hole on valve pocket surface is square; As shown in Figure 2; When using auxiliary pole of the present invention and treating the side valve cover and test, it is square at first selecting light hole, with the auxiliary pole of valve pocket socket to be measured; The through hole of being opened on the feasible auxiliary pole of the auxiliary pole of rotation then and the corresponding tapering that also utilizes auxiliary pole of square hole of valve pocket to be measured; With valve pocket to be measured along auxiliary pole by the little place of diameter push to the diameter general goal make between valve pocket to be measured and the auxiliary pole interference fit and fixedly become one, after the square hole of confirming valve pocket to be measured still satisfies the test printing opacity and requires, after promptly assisting pole not treat square hole printing opacity that side valve overlaps to hinder to some extent; Its cone centre through two ends on the universal tool-measuring microscope is headed into the taper pilot hole 1 of assisting the pole two ends, treat the correlation parameter of side valve cover and implement to measure.
Claims (2)
