Description
Technical field
The utility model relates to a kind of hole heart apart from measurement mechanism.
Background technology
On rain shaving electrical machine reducer shell, have two mutual vertically arranged dead eyes, the distance between these two dead eyes is that part quality is controlled one of index.At present, for the distance between these two dead eyes, conventionally all adopt three coordinate machine metering, still, three coordinate machine must be placed in the environment of regulation, instrument volume is large, need special survey crew, Measuring Time is long, efficiency is low, cost is high, to production, makes troubles, and affects manufacturing schedule, can only inspect by random samples, in the time of should not producing in batches in production scene, measure.And the diameter of actual production mesopore always exists foozle, can not equal absolute some values, but fluctuate in its design size margin tolerance.
Summary of the invention
For above-mentioned technical matters, fundamental purpose of the present utility model is for providing a kind of hole heart apart from measurement mechanism, the error that the utility model can two hole heart distances of Measurement accuracy.
The hole heart is apart from measurement mechanism, comprise measuring seat, one end of measuring seat is provided with fixedly gauge head, fixedly gauge head is L-shaped for this, the lower surface of measuring seat is provided with a Connection Block, one end of a movable gauge head is hinged on this Connection Block, fixedly gauge head and movable gauge head are state arrangement in opposite directions, the hinged one end of movable gauge head and Connection Block is provided with a horizontal expansion piece, the end of this extension block is connected with one end of a spring, the other end of spring is connected with measuring seat, described measuring seat is provided with through hole, the measuring staff of a dial gauge contacts with the extension block of movable gauge head through after described through hole.
Adopted such scheme, during measurement, fixing gauge head is put in first hole on workpiece, movable gauge head 4 is put in second hole, by the measuring staff of dial gauge, press down the extension block of movable gauge head, make movable gauge head and fixedly gauge head be close to corresponding wall surface of the hole separately respectively, by reading the minimum dimension on dial gauge, deviate on dial gauge is error and the two hole real radius error sums of actual apertures heart distance, measure two hole real radius errors, can calculate the actual apertures heart apart from error.
On described measuring seat, be threaded one and adjust screw, this end face of adjusting screw contacts with extension block lower surface.By adjusting screw, the amplitude of oscillation that can adjustment activity gauge head, is conducive to improve the precision of measuring.
In the through hole of described measuring seat, fix a sleeve, one end of this sleeve passes the outside of through hole, and dial gauge is fixed on this sleeve, and the measuring staff of dial gauge contacts with the extension block of movable gauge head through after sleeve.By sleeve, coordinate with dial gauge, make the location of dial gauge more accurate, be conducive to improve the precision of measuring.
Accompanying drawing explanation
Fig. 1 is that the hole of the present utility model heart is apart from measurement mechanism structural representation;
1 is measuring seat, and 2 is fixing gauge head, and 3 be Connection Block, and 4 is movable gauge head, and 5 is extension block, and 6 is spring, and 7 is dial gauge, and 8 is adjustment screw, and 9 is sleeve, and 10 is workpiece.
