Abstract
The utility model relates to a balance type intelligent measurer with small module gears for measuring the small gears of instruments and meters. A stepper motor drives a standard measuring gear by a hand wheel and a harmonic speed reducer. The measured gear engaged with the standard measuring gear is installed on one end of a balance type rocker, and the center of the balance type rocker is supported on an upright post of an elevating screw. An amesdial and weights are arranged on the end part of the balance type rocker. The output of an amesdial is communicated to a computer by an interface card, and the output of a computer is communicated to a printer. The balance type intelligent measurer with small module gears has the advantages that the precision is high, the measuring force can be optionally controlled starting from zero, and the plastic gear and the gear which lacks teeth can be measured.
Description
The utility model relates to a kind of gear measurement machine, the fine module gear measuring instrument of pinion wheel in particularly a kind of surveying instrument instrument.
Fine module gear is the important foundation element of instrument and meter, and multiple fine module gear for example just is housed in the camera, and their quality is good and bad, is determining machine performance.The modulus of fine module gear is very little, and generally its modulus is less than 1, and structure is of a great variety, causes very big difficulty to detection.If detection level falls behind, will cause fine module gear interchangeability poor, transmission is dumb, and is that have even stuck.
The CA120 type double gearing apparatus structure similar that little modulus double gearing apparatus that Britain Mikron company produces and measuring and cutting tools plant, BeiJing, China produce is used to measure fine module gear.The structure of these two kinds of double gearing apparatus is: the canonical measure gear shaft is installed on the fixed mount, be installed on the rolling planker with the central shaft of the tested gear of its engagement, use micrometer, as clock gauge, detect the displacement of rolling planker, thereby detect the deviation of two gearing mesh process centre distance.The Chinese Shanghai Mechanical Academy identifies that in April, 1991 " the intelligent double gearing apparatus " that pass through is on the basis of the CA120 type double gearing apparatus that Beijing Measuring and Cutting Tools Factory produces; the transmission gear that drives with a micromachine removes to drive the canonical measure gear; with pulley and counterweight tested central gear axis is applied ergometry; the displacement of rolling planker is by inductance sensor input recorder and microprocessor, and the output of microprocessor connects printer.The structural principle of the mechanical measurement of above-mentioned three kinds of double gearing apparatus part is identical, all exists following shortcoming: the 1. ergometry control arbitrarily of can't starting from scratch; 2. the drag-cup type of rolling mechanism is sensitive inadequately; 3. the canonical measure gear has outside interference, influences measuring accuracy.So the measuring accuracy of these double gearing apparatus is not high, and can not be used to measure little module Plastic Gear.
The purpose of this utility model is to provide a kind of high-precision fine module gear measuring instrument, and measuring accuracy height not only, its ergometry can be started from scratch and be adjusted arbitrarily, thereby can survey arbitrarily small plastic gear.
For achieving the above object, the utility model adopts following technical proposals: the same canonical measure gear that is driven by micromachine that includes with prior art of this fine module gear measuring instrument.With the tested gear of canonical measure gearing mesh and the dial gauge of measuring tested gear shaft displacement.Be characterized in: tested gear shaft is installed in an end of balance-type type fork, the balance-type type fork is supported on the top of an elevating screws column in the center, the counterbalance weight that can transpose is housed on the balance-type type fork, the ergometry counterweight is placed in the end of balance-type type fork in the end of the measurement thimble conflict balance-type type fork of dial gauge.During use, after installing tested gear and placing dial gauge, adjust the counterbalance weight position, make the balance-type type fork be in equilibrium state, this moment, ergometry was zero.Then, as required, can add counterweight arbitrarily, thereby can adjust ergometry arbitrarily.Because adopt the balance-type type structure, highly sensitive, the canonical measure gear is not subjected to outside interference, so the measuring accuracy height.Adjust control arbitrarily because ergometry can be started from scratch, can be used for measuring arbitrarily small plastic gear, prevent that compressive deformation influences measuring accuracy because ergometry is excessive in its measuring process.
Micromachine of the present utility model can be selected micro-step motor for use, and its output shaft can connect handwheel, Harmonic ripple speed reduction unit, speed reduction unit successively and connect and drive the canonical measure gear shaft.Like this, both can electronicly measure, but also manual measurement, and the control micro-step motor can go to detect any tooth group in the tested gear with any tooth group in the canonical measure gear.Like this, also can be used for measuring incomplete agomphosis gear.
Dial gauge of the present utility model can adopt inductance amesdial and grating dial gauge.The inductance amesdial precision is higher than the grating dial gauge, but the inductance amesdial range is less than the grating dial gauge, so both can be used, with the absolute altitude of grating dial gauge assay balance formula fork column with the centre distance after measuring two gearing mesh first, accurately measure with inductance amesdial then.
The utility model can dispose a cold light source, its emission light beam irradiates canonical measure gear and tested gearing mesh place.And settle an entity to become power microscope in the dead ahead at this two gearing mesh place.Like this can be by the gear teeth of microscopic examination engagement, whether can check has the foreign matter influence to measure, also can recognize the mark of the initial tested gear teeth on these gear teeth.
The utility model also can carry out intellectuality: micro-step motor is connected computer by the stepper motor interface card, inductance amesdial and grating dial gauge are connected computer by interface card separately respectively, the output of computer connects printer, and AC power is powered to cold light source, inductance amesdial, grating dial gauge, computer and printer by stabilized voltage supply.
The utility model compared with prior art, have following conspicuous advantage: owing to adopt the balance-type type structure, highly sensitive, the measuring accuracy height, Manufactured model machine precision can reach 0.010～0.020 micron, can be used for surveying modulus and less than 0.5 precision be 7～10 grades pinion wheel; Ergometry can be started from scratch and be added counterweight arbitrarily, can measure arbitrarily small plastic gear, as measuring the plastics pinion wheel with 10 grams, can obtain preferable measurement effect; Owing to adopt handwheel and micro-step motor, any tooth group of available standards prototype gear goes to detect any tooth group of tested gear, the gear that is suitable for producing in enormous quantities detects with the tooth group of same canonical measure gear, improve measuring accuracy, can be used for measuring incomplete agomphosis gear simultaneously; Can also measure two centre distance errors of nibbling.
