Abstract

An inner hole basis positioning subsidiary measurement device is the subsidiary measurement device which is used for length measurement and takes a connection line of two hole centers as positioning or measuring basis for detecting other parameters of parts; the subsidiary measurement device can solve the shortcoming of low-efficiency of the prior measurement; the inner hole basis positioning subsidiary measurement device is composed of a pressing cover, a sliding block, a taper pin with a thread, a connecting rod, a shell body, a handle, a base, a fastening screw and a spring, wherein, an inner thread hole is made in the shell body, and three grooves and a spring mounting hole are made at the upper end thereof, one end of the sliding block is made into a trapezoidal spiral bevel, a spring hole is made on the sliding block, the sliding block is arranged in the grooves of the shell body, the spring is arranged in the spring hole, the pressing cover is arranged on the shell body and fixed on the shell body by using the fastening screw, one end of the taper pin with the thread is made into the shape of a cone and the surface thereof is made into the shape of a trapezoidal spire, an inner hole and an outer thread are made on the other end, the taper pin with the thread is arranged in the inner thread hole of the shell body, the taper pin with the thread is arranged on the connecting rod, the handle is arranged on the connecting rod, and the connecting rod is arranged on the base; the subsidiary measurement device has the advantage of high measurement efficiency.

Description

Internal hole reference positioning auxiliary measuring device

Technical field:

The invention is to be applied to length by length metering, and by two hole heart lines as location or measuring basis, detect the aided measurement device of other parameters of parts.

Background technology:

In the length metering industry; run into through regular meeting that (hole might be a threaded hole by two holes; the light face; splined hole) heart line is as location or measuring basis; detect other parameters of parts; can be used in two hole heart lines at present as location or measuring basis; detect the measuring equipment of other parameters of parts; it mainly is the tool microscope of measuring based on the three coordinate measuring machine and the image method of contact measurement; when two Kong Weiguang faces, be the easiest method fast and accurately with the three-dimensional coordinates measurement machine testing; when having one or two to be threaded hole or splined hole in two holes, touch survey and the measurement data poor repeatability will occur with the sphere of three coordinate measuring machine or cylindricality probe; the result is inaccurate; the tool microscope that this moment, image method was measured is first-selected measuring equipment just; but the shortcoming of measuring with tool microscope is that centering is entirely with feel and experience; need the repeated multiple times centering; waste time and energy, efficient is too low.

Summary of the invention:

The purpose of the invention provides a kind of internal hole reference positioning auxiliary measuring device that can save Measuring Time; The purpose of the invention is to realize by following technical scheme: internal hole reference positioning auxiliary measuring device, it is characterized in that by gland, slide block, the taper thread pin, connecting link, housing, handle, base, trip bolt, spring is formed, housing is shaped on the internal thread hole that cooperates with the taper thread pin, the upper end is shaped on three grooves and the spring mounting hole that cooperates with slide block, slide block one end is made trapezoid spiral shape inclined-plane, make spring eye on the slide block, slide block is installed in the groove of housing, spring is installed in the spring eye, gland is installed on the housing and with trip bolt is fixed on the housing, taper thread pin one end is made its surface of taper and is made the trapezoid spiral shape, the other end is made endoporus and external thread, the taper thread pin is installed in the internal thread hole of housing, the taper thread pin is installed on the connecting link, handle is installed on the connecting link, and connecting link is installed on the base.

The advantage of the invention: location, two holes aligning method is simple under internal hole reference positioning auxiliary measuring device cooperates, improved the work efficiency of measuring, time saving and energy saving, be through with and adjust part repeatedly, spur repeatedly the slide plate of tool microscope complete by rule of thumb with the centering mode of feel; This apparatus structure compactness, easy to use.

Embodiment:

Internal hole reference positioning auxiliary measuring device, it is characterized in that by gland, slide block, the taper thread pin, connecting link, housing, handle, base, trip bolt, spring is formed, housing is shaped on the internal thread hole that cooperates with the taper thread pin, the upper end is shaped on three grooves and the spring mounting hole that cooperates with slide block, slide block one end is made trapezoid spiral shape inclined-plane, make spring eye on the slide block, slide block is installed in the groove of housing, spring is installed in the spring eye, gland is installed on the housing and with trip bolt is fixed on the housing, taper thread pin one end is made its surface of taper and is made the trapezoid spiral shape, the other end is made endoporus and external thread, the taper thread pin is installed in the internal thread hole of housing, and the taper thread pin is installed on the connecting link, handle is installed on the connecting link, and connecting link is installed on the base.

Gland, slide block, housing can be made the series specification of different-diameter according to the aperture, select for use the specification that is fit to the aperture to measure during measurement, internal hole reference positioning auxiliary measuring device is put into the exemplar hole, rotation taper thread pin makes its rising, the taper of taper thread pin is extrapolated with slide block, slide block props up the hole inner face, this moment, internal hole reference positioning auxiliary measuring device was contained in the endoporus, and the internal hole reference positioning auxiliary measuring device that exemplar will be housed again passes through the anchor clamps clamping on the worktable of tool microscope.Begin to measure: adjust rice word line angle in the tool microscope eyepiece, make it be in 0 degree position, Move tool microscope inner slider, make eyepiece field of view interior rice word line and first datum hole tangent, then tool microscope Y direction slide plate is fixed, directions X moves universal tool-measuring microscope slide plate to the second a datum hole place, see whether meter word line is tangent with second datum hole, if not tangent handle that needs to rotate internal hole reference positioning auxiliary measuring device, make the Kong Xinwei basic point rotation of exemplar with first datum hole, Y direction slide plate is motionless, adjust the rice word line position about directions X, make in the eyepiece field of view rice word line tangent, just finished under the looking for of exemplar and worked with next hole.During measurement, time saving and energy saving without repeated multiple times, the efficiency of measurement height.
