At present, gear division motor (comprising high-speed air turbine mobile phone) rotating speed can by thousands of turn per minute reach 300,000 turn per minute more than, output torque is conventionally within the scope of 0.05Ncm～5Ncm, and conventional dynamometer machine working speed turns below per minute 25000 conventionally, conventional dynamometer machine loads torque precision and is generally 0.1Ncm～1Ncm, therefore can not meet gear division motor detecting needs.In addition, except straight handpiece, dental handpiece is all with specific angle, if can not realize the accurately coaxial of mobile phone, drill bit and dynamometer machine, in test by original just very little output torque was brought to great test error, even destroy tested drill bit.
Summary of the invention
The purpose of this utility model solves existing dynamometer machine and can not meet the problem of gear division motor detecting needs, provide one to be applicable to gear division motor, comprise pneumatic and special torsion-testing apparatus electro-motor, make this device can fix all kinds of gear division motors and straight handpiece, contra-angle handpiece, high-speed air turbine mobile phone, motor is applied to adjustable magnetic hysteresis moment of torsion, torque range is from 0.01Ncm～5Ncm, precision 0.01Ncm, and energy Real-Time Monitoring motor rotary speed, the response range of speeds 0.1 turns per minute～1,000,000 and turns per minute.
The gear division motor torsional moment proving installation that the utility model provides, comprise test platform, a replaceable Mobile phone base is installed on test platform, Mobile phone base upper surface offer one with the identical groove of mobile phone profile, the utility model provides three kinds of Mobile phone bases, groove on Mobile phone base corresponds respectively to the physical dimension of straight handpiece, contra-angle handpiece and high-speed air turbine mobile phone, for laying three kinds of mobile phones.There is standing screw Mobile phone base top by frame installation fixing on test platform, and briquetting is equipped with in standing screw lower end, and briquetting lower surface is cambered surface, for compressing the mobile phone on Mobile phone base.On the test platform of Mobile phone base one side, support is installed, carriage center is provided with the hole of passing for prod, and this hole is coaxial with mobile phone chuck, and prod packs mobile phone chuck locking into; The utility model provides and meets 3 kinds of prods that YY 1045.2 specifies, prod is all through magnetization, and with the black and white strip along axis direction.Be provided with laser tachometer gage perpendicular to the direction of prod, hot spot that laser tachometer gage sends is aimed at the black and white strip on prod, and laser tachometer gage measurement range is 0.1 to turn per minute～1,000,000 and turn per minute.Prod front end is around around solenoid, and solenoid is connected to constant-current supply, and the tail end of mobile phone can be connected with tested gear division motor 11.
advantage of the present utility model and good effect:
The utility model provides dental handpiece base used specially, be convenient to fixing various types of dental handpieces, lower range, high-precision magnetic hysteresis coil and high-rate laser tachometer gage are provided, contain the performance index scope of current all types gear division motor, can regulate continuously and load load, complete the test of gear division motor torsional moment.

Embodiment
embodiment:
As shown in Figure 1, gear division motor torsional moment proving installation, comprises test platform 1, on test platform 1, by bolt, a replaceable Mobile phone base 2 is installed.Mobile phone base upper surface offer one with the identical groove of mobile phone profile, the utility model provides three kinds of Mobile phone bases, the groove on Mobile phone base corresponds respectively to the physical dimension of straight handpiece, contra-angle handpiece and high-speed air turbine mobile phone, for laying three kinds of mobile phones.
Be positioned at Mobile phone base 2 tops, by framework fixing on test platform 12, standing screw 3 be installed, briquetting 4 is equipped with in standing screw 3 lower ends, and briquetting 4 lower surfaces are cambered surface, for compressing the mobile phone 5 on Mobile phone base 2, mobile phone chuck in-built enter prod 7.Mounting bracket 6 on the test platform of Mobile phone base 2 one sides, support 6 centers are provided with the hole that can pass for prod 7, and this hole is coaxial with mobile phone chuck, and prod is all through magnetizing, and with the black and white strip along axis direction.Be provided with laser tachometer gage 8 perpendicular to the direction of prod 7, the launch spot of laser tachometer gage 8 is aimed at the black and white strip on prod 7, and prod 7 is coaxial around solenoid 9(two axial lines around), solenoid 9 is connected to constant-current supply 10.The tail end of mobile phone can be connected with tested gear division motor 11.
