Abstract

The utility model relates to a measuring tool, in particular to a tool for measuring swelling capacity of outer diameter, which solves the problem that the tiny changes of the diameter of an inner ring of a bearing is difficult to measure caused by interference fit of a rotating shaft and a small gear, and comprises a semicircle skeleton which is consistent with the circle center position of a measured object, the inner sides of the two ends of the semicircle skeleton are equipped with two slices which respectively are a side position slice and a measure slice, the inner side of the middle portion of the semicircle skeleton is equipped with a middle position slice, one ends of the side position slice and the middle position slice extend from the side surface of the semicircle skeleton, the two ends of the measure slice are higher than the two sides of the semicircle skeleton, the measure slice is articulated with the semicircle skeleton through a fulcrum, a support is fixed on one end of the measure slice, which is equipped with the semicircle skeleton, the support is equipped with a dial indicator, and the dial indicator is connected with the measure slice. Through using the tool for measuring the swelling capacity of the outer diameter to assemble the small gear, the bearing and a shaft for a motor with an inner core combining structure, the swelling capacity of assembled parts can be accurately measured in real time.

Description

External diameter swell increment measurer
Technical field
The utility model relates to a kind of survey instrument, is specially a kind of external diameter swell increment measurer.
Background technology
In mechanical transmission fields, axle and the fit dimension of the magnitude of interference, rotating shaft and the bearing inner race of gear and the radial play of bearing inside, reliability, particularly bearing life and the reliability that quality of fit affects kinematic train greatly.Machine shaft and pinion wheel are the inner cone interference fit, for the swell increment of guaranteeing bearing inner race is lasting controlled, must constantly detect the change in size of bearing inner race in the assembling process of pinion wheel.Because when the pinion wheel taper surface adopts the mode of oil pressure propelling to enter the rotating shaft inner cone, because the relation of the magnitude of interference, the external diameter of rotating shaft will constantly produce small expansion, the expansion of the external diameter of rotating shaft simultaneously can have influence on the bearing inner race external diameter, the variation of the rotating shaft external diameter that constantly the pinion shaft conical surface is entered the rotating shaft inner cone and produce passes to bearing inner race, because the process of this being pressed into-expand-expansion again is the process of a gradual change, and properties of materials also has certain dispersiveness, and it is necessary therefore in this process the swell increment of bearing outer ring being detected in real time.But ordinary measring tool (vernier caliper, cylindrical slide calliper rule) can't satisfy real-time measurement requirement owing to be subjected to space constraint, and this base part generally has very high machining precision, and assembling back change in size amount is also very little, is difficult for accurately measuring.
Summary of the invention
The bearing inner race diameter subtle change that the utility model causes in order to solve interference fit between rotating shaft and pinion wheel is measured the problem of difficulty and a kind of external diameter swell increment measurer is provided.
The utility model is realized by following technical scheme, a kind of external diameter swell increment measurer, comprise the semicircle skeleton consistent with the measured object home position, be provided with two thin slices in inboard, semicircle skeleton two ends, be respectively limit location thin slice and measure thin slice, location thin slice in the inboard, middle part of semicircle skeleton is provided with, one end of limit location thin slice and middle location thin slice stretches out in the side of semicircle skeleton, the two ends of measuring thin slice are all above semicircle skeleton both sides, it is hinged by fulcrum and semicircle skeleton to measure thin slice, an end that is provided with the semicircle skeleton of measuring thin slice is fixed with support, and support is provided with dial gauge, and dial gauge is connected with the measurement thin slice.
Semicircle frame design described in the utility model is identical with the bearing inner race center of circle, arrange three rigid sheet along circle in the arc skeleton, three rigid sheet are blocked bearing outer ring and tangent with the circular arc of bearing outer ring, circle is tangential distribution in the plane of rigid sheet and the arc skeleton, the position distribution of rigid sheet is two of the two ends of semicircular arc skeleton diametric(al)s, one at place, arc top can do short-range displacement when the thin slice (measurement thin slice) on the diametric(al) is stressed.The length of thin slice is wherein located thin slice and is stretched out skeleton in a side greater than the thickness of skeleton, measures the thin slice both sides and all stretches out skeleton, the extension of three thin slices is placed on the outside surface of bearing inner race.Measure thin slice and utilize lever principle, between skeleton and measurement thin slice, preloading spring and fulcrum are installed.Measure thin slice and just be pre-compacted on measured workpiece, at this moment adjust dial gauge to " 0 ", be exactly the original outer diameter of bearing inner race this moment.When being pressed into pinion wheel, constantly expand in the axle journal place, and bearing inner race is also risen greatly.Measure thin slice one end and will constantly move upward this moment, and on the contrary, the other end moves downward, and the dial gauge correspondence demonstrates the variable quantity of internal diameter.
According to different measuring occasion, measuring workpieces, design different semicircle skeletons, determine that to realize three points on the same plane how much laws of a circle are criterion, rigid sheet and semicircle skeleton are installed the back and are guaranteed to have essentially identical diameter with measured workpiece, a spring and the promise measurement thin slice measured under the thin slice have certain scope of activities, and this scope is greater than the design swell increment of workpiece.
Utilize the utility model for the motor of inner cone fit structure when pinion wheel, bearing and the axle assembling, the measurer that can measure in real time the built-up member swell increment: utilize three points on the same plane to determine how much laws of a circle; Measure thin slice and can stretch into workpiece, utilize lever principle, realize the accurate measurement of dial gauge than in the small gap.
