Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.
Endoporus adjacent grooves gap measuring device shown in Fig. 1 is the embodiment for detecting the adjacent deep gouge spacing dimension of Semi-shaft bevel gear of automobile differential endoporus.This cubing comprises gauge block 1, end cap 2, slide plate 3, pin 4, pedestal 5, key seat 6, supporting 7, gauge rod 8, spring 9, cylindrical shell 10 and dial gauge 11.Described gauge block 1 is a kind of scale device made by the adjacent deep gouge spacing dimension of workpiece for measurement endoporus, and its side is T-shaped as shown in Figure 4, and namely a disk adds a straight-bar.For the ease of measurement operation, the height dimension of gauge rod 1 is smaller than workpiece for measurement endoporus adjacent deep gouge spacing, and the adjacent deep gouge spacing of the present embodiment workpiece is 49.075 ± 0.05mm, is decided to be 48 ± 0.002mm for gauge block 1 height dimension detected.Before detection as shown in Figure 7, first gauge block 1 is placed in inner hole of workpiece, the disk bottom face stop bit of gauge block 1 is in inner groove limit, and straight-bar end face upward treats gauge rod 8 contact measurement.This measure be with inner groove limit for benchmark, make measure simplify, convenient.The end cap 2 be stacked successively, pedestal 5 and key seat 6 are Flange-shaped Parts, and middle reserved hole is convenient to cylindrical shell 10 and is inserted.The cylindrical of end cap 2 and workpiece calibration port part endoporus clearance fit, superpose pedestal 5 and key seat 6 successively on end cap 2.Uniform 3 radial opening grooves on the end face that described pedestal 5 faces inner hole of workpiece, in every radial opening groove, an equipped slide plate 3, pedestal 5 end face is also provided with the isocentric circular arc groove 5.1 matched with radial opening groove.Described pin 4 is cylindrical pin, and the downward axial order of pin 4 cylindrical section runs through the isocentric circular arc groove 5.1 of pedestal 5 and the eccentric arc groove 3.1 of slide plate 3, and pin 4 and key seat 6 interference fit, the slide plate 3 that can radially slide is by end cap 2 axial limiting of outer connection.A measuring seat is as shown in Figure 5 connected to form by above-mentioned, relative rotation key seat 6 and pedestal 5, make built-in pin 4 limit slide plate 3 and do radial displacement by the track of eccentric arc groove 3.1, the displacement of slide plate 3 outward radial makes outer chimb be inserted in the outer deep gouge of workpiece, and measuring seat is provided with and is beneficial to subsequent detection under location condition.After measurement terminates, opposite base 5 rotates key seat 6 in the other direction, is got back to by slide plate 3 in pedestal 5, because measuring seat is axially accessible, is convenient to lay down measuring seat from workpiece top.The isocentric circular arc groove 5.1 be located in said structure on pedestal 5 end face is identical with eccentric arc groove 3.1 shape on slide plate 3 end face, only the center of circle of eccentric arc groove 3.1 is biased clockwise, it is little that the present embodiment reserves amount of bias, as long as slide plate 3 radial displacement 2.5mm is just enough to location.Described cylindrical shell 10 is main components of composition gauge head, and cylindrical shell 10 is a kind of elongated tubulars, upper end mouth of pipe plug-in mounting dial gauge 11, and the table bar of dial gauge 11 is subject to the built-in spring 9 of cylindrical shell 10 and gauge rod 8 to control axial displacement.Join spring 9 in the utility model and belong to pressure spring, under elastic reaction, gauge rod 8 bottom holds greatly the mouth of pipe to expose from cylindrical shell 10.First cylindrical shell 10 bottom to be inserted into during installation in the key seat 6 be stacked and pedestal 5 endoporus and axial stop bit in slide plate 3 upper surface, the exposed junction of gauge rod 8 directly pushes up gauge block 1 upper surface, forms gauge block 1 axial location in inner hole of workpiece thus and quantizes detection architecture by dial gauge 11.
The utility model is inserted in the outer deep gouge of inner hole of workpiece for the ease of slide plate 3 smoothly; at pedestal 5 outer edge, 3 axial adjustable elastic bearings 7 are installed; supporting 7 and the workpiece aperture end face Elastic Contact erect; the axial length of supporting 7 adjusts in advance; guaranteeing the bottom face of slide plate 3 bottom face higher than the outer deep gouge of workpiece for measurement endoporus without External Force Acting lower support 7, both the present embodiment difference in height is 0.5mm.Slightly apply some power during detection just can overcome the elastic force of supporting 7 and eliminate micro-difference in height, the outer chimb radial direction being convenient to slide plate 3 is inserted in the outer deep gouge of inner hole of workpiece.
In order to accomplish Quick Measurement, accurately measure, when measuring with a collection of workpiece, first by dial gauge 11 zero check of the gauge head configuration in the utility model, must namely determine gauge rod 8 exposed junction and standard component upper surface contact position.Use the gauge head of zero check to measure the adjacent deep gouge spacing dimension of workpiece for measurement endoporus as shown in Figure 9, before this, first press the order shown in Fig. 7 and Fig. 8, toward workpiece for measurement endoporus, gauge block 1 is installed, then install and measure seat at workpiece for measurement endoporus oral area.Because workpiece exists mismachining tolerance during detection, the zero-bit of dial gauge 11 indicating value and the setting of gauge outfit configuration has deviation, and the deviate of testing staff's reading compares with design load, final quantization judgement inner hole of workpiece adjacent deep gouge spacing deviation value and direction whether qualified.
By the location on the adjacent deep gouge limit of endoporus when the utility model is measured, distance measurement between the adjacent deep gouge be among endoporus is changed into depth survey.This measures, and structure is simple, simple operation, can do the accurate measurement of mechanical component endoporus adjacent deep gouge spacing with conventional length measurer, can objectively respond machining deviation size and bias direction, be conducive to improving following process quality owing to quantizing detection.
