Embodiment
By particular specific embodiment explanation embodiments of the present invention, person skilled in the art scholar can understand other advantages of the present invention and effect easily by the disclosed content of this instructions below.
Refer to Fig. 1 to Fig. 3.Notice, appended graphic the illustrated structure of this instructions, ratio, size etc., equal contents in order to coordinate instructions to disclose only, for person skilled in the art scholar, understand and read, not in order to limit the enforceable qualifications of the present invention, therefore the technical essential meaning of tool not, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under the effect that the present invention can produce and the object that can reach, all should still drop in the scope that disclosed technology contents will contain.Simultaneously, in this instructions, quote as " on ", the term of D score, " left side ", " right side ", " centre " and " " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the present invention, the change of its relativeness or adjustment, under without essence change technology contents, when being also considered as the enforceable category of the present invention.
As shown in Figure 1, 2, the invention provides the symmetry degree gauge of the corresponding datum hole of a kind of valve pocket oil groove, this symmetry degree gauge comprises a base plate 1, base plate 1 is provided with a locating shaft 2, locating shaft 2 is fixed on base plate 1, locating shaft 2 is provided with between relative 21, two radial holes 21 of radial hole in two positions 180 °, interval.In each radial hole 21, be equipped with a steel ball 23, between steel ball 23 and the bottom of radial hole 21, be provided with spring 22, steel ball 23 can move around in radial hole 21.Steel ball 23 is limited in radial hole 21, under the elastic force effect of spring 22, and the extended radial hole 21 of a part for steel ball 23, a part for steel ball 21 is protruded on the outer peripheral face of locating shaft 2.Be enclosed within on locating shaft when valve pocket 7 like this, and the oil groove 71 of valve pocket is when corresponding with radial hole position on locating shaft 2, a part for steel ball 23 evaginations will be stuck in the oil groove 71 of valve pocket 7.The diameter of steel ball 23 should be greater than the width of valve pocket 7 inner oil sumps 71, and guarantee valve pocket 7 is clamped like this, avoids valve pocket 7 to rotate on locating shaft 2.
A side at locating shaft 2 is also provided with a measurement piece 3, measures piece 3 and is slidably connected with base plate 1, and base plate 1 is provided with slide rail 4, measures piece 3 and is provided with slide block, and slide block coordinates with slide rail 4 to be made to measure piece 3 and slidably reciprocate on base plate 1.Measure piece 3 and be provided with a sounding rod 31 that points to locating shaft 2, the center line of sounding rod 31 should be vertical with the center line of radial hole 21 on locating shaft 2, the glide direction of measuring piece 3 should be parallel with the centerline direction of radial hole 21, so slide rail 4 arranged direction should be parallel with the centerline direction of radial hole 21.In a side of measuring piece 3, be provided with clock gauge 5, opposite side is provided with clock gauge 6, the measuring staff of clock gauge 5, clock gauge 6 is resisted against respectively the both sides of measuring piece 3, installation for the ease of clock gauge, can an extension plate 32 be set respectively in the both sides of measuring piece 3, the measuring staff of clock gauge 5,6 only need be resisted against respectively on the extension plate 32 of measuring piece 3.
As shown in Figure 3, as a preferred embodiment, steel ball 23 can be limited in radial hole 21 by two banking stops 24, two banking stops 24 cover a part by the two ends up and down of radial hole up and down relatively, so just steel ball 23 can be limited in radial hole 21, and the part that can guarantee steel ball 23 stretches out radial hole 21, banking stop 24 is fixed on the outer peripheral face of locating shaft 2.As a kind of optimal way, on banking stop 24, semi-circular hole can be set, semi-circular hole on two banking stops 24 is relative, can guarantee like this steel ball 23 being limited under the prerequisite in radial hole 21, on steel ball 23, there is larger part can stretch out radial hole 21, generally as long as the diameter of semi-circular hole is slightly less than the diameter of steel ball 23.
Being used for one end of the valve pocket 7 that detects is provided with the datum hole 72 of an opening, is provided with eight equally distributed oil grooves 71 on the inner peripheral surface of valve pocket.When detecting, the datum hole 72 of valve pocket 7 should be positioned near a side of measuring piece 3, valve pocket 7 is enclosed within on locating shaft 2, the steel ball 23 in two radial holes 21 on locating shaft 2 is stuck in the corresponding oil groove 71 of valve pocket 7, the sounding rod 31 that simultaneously makes to measure on piece 3 is inserted in datum hole 72.After valve pocket 7 packages, the position of traverse measurement piece 3, makes the axis of sounding rod and the center superposition of locating shaft 2, generally can on base plate, be provided with a mark line, on sounding rod 31, arrow is set, only needs traverse measurement piece 3 that arrow is overlapped with mark line simultaneously.Now at levelling clock gauge 5,6, clock gauge is made zero, and then slidably reciprocates and measure piece 3, make sounding rod 31 respectively with two contacts side surfaces of datum hole 72, the reading of observing two clock gauges can be judged the symmetry of the corresponding datum hole of valve pocket oil groove.
This cubing is simple in structure, easy to use, can not be subject to the impact of iron filings in valve pocket, is difficult for breaking down, and can effectively improve the detection efficiency of valve pocket.So the present invention has effectively overcome various shortcoming of the prior art and tool high industrial utilization.
