Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
As shown in Figure 1, conical surface bounce gauge of the present invention, comprises disc location-plate 1, cubing body 2, lining 3, tight fixed bolt 4 and clock gauge 5; As shown in Figure 3, on location-plate 1, offer several via holes relative with workpiece 6 conical surface corresponding aperture positions, in the middle of location-plate 1, also offer the center pit corresponding with protruding (recessed) face gear ring position in the middle of workpiece; As shown in Figure 2, described cubing body 2 is circular stepped, offers the through hole for fixing clock gauge 5 on cubing body 2, and tight fixed bolt 4 is fixing with cubing body 2 by clock gauge 5 through cubing body 2; By the convex surface gear ring through workpiece 6 by the center pit of location-plate 1, and the lower surface of location-plate 1 and workpiece 6 upper surfaces are fitted, make via hole on location-plate 1 and the conical surface corresponding aperture position alignment of workpiece 6, cubing body 2 is inserted in the hole that workpiece 6 conical surface to be checked is corresponding through location-plate 1 via hole, and supporting surface on 2 times locating surfaces of cubing body and location-plate 1 is fitted, clock gauge 5 inserts in cubing body 2 through holes fixing by tight fixed bolt 4, clock gauge 5 gauge outfits compress the conical surfaces, by cubing body 2 conical surface glitch detection that rotated a circle.
Further, because hole dimension in workpiece 6 conical surface correspondences has the foozle of 0-0.05mm, when measurement, cubing body-centered axle rotation can directly affect measurement result with respect to measured bore axis coaxle degree error.For this reason, every cover cubing is made the different cubing bodies of 3 diameters according to inner hole of workpiece size, to meet the needs of different location dimensions, between the location dimension of each cubing body, differs 0.02mm.Select cubing body according to the physical size of inner hole of workpiece, so just have and tolerance clearance can be controlled in 0.02mm effectively.With the tolerance contrast of this 0.13mm that beats own, such error is completely negligible.
Further, in the through hole of described cubing body 2 for fixing clock gauge 5, lining 3 is installed, avoids contact friction between clock gauge and cubing body through hole, reduce the effect of the infringement of clock gauge being played to protection clock gauge.
Meanwhile, due to the impact of inner hole of workpiece gap and cubing body-centered shaft length, measure the cubing body centre of gyration and measured bore axis and easily produce inclination.Adopt positioning plate structure for this reason, the support strict guarantee by location-plate the cubing body centre of gyration and part end face vertical.The gear ring cylindrical on the center pit of location-plate and workpiece two sides adopts clearance fit, and end face contacts to ensure cubing body and verticality endoporus with workpiece upper and lower surface.Meanwhile, the outer fenestra of several via holes of location-plate 1 and cubing body 2 adopts clearance fit.Eliminated the situation of crossing location by two clearance fit.
The course of work of cubing: when Workpiece inspection, first multiple cubing bodies filled in inner hole of workpiece to be checked according to the size of location dimension successively or accurately measure the size in this hole, picking out a cubing body of tolerance clearance minimum.Afterwards the center pit of location-plate is placed on to measured workpiece protruding (recessed) face gear ring cylindrical, rotation slowly running fix plate, until align substantially with six holes of measured workpiece in six holes on location-plate.Finally by cubing body through the hole on location-plate, be inserted in gaging hole to be checked, and make supporting surface laminating on locating surface and location-plate under cubing body, guarantee cubing physical efficiency is freely rotated.Insert clock gauge, gauge outfit is contacted with the tested conical surface, and allow dial plate pointer in the time of rational position, fix clock gauge.Compress cubing body, and rotate a circle, record clock gauge minimax variation range and be conical surface jitter values.
Cubing of the present invention is simple in structure, cheap for manufacturing cost.Be size according to existing hole, only need to manufacture two cover cubings and can complete the detection that such part conical surface is beated.Compared with original three-dimensional detection mode, greatly improve measurement efficiency, reduced the convenience of measuring cost, having improved measurement.
