Description
Technical field
The present invention relates to dental handpiece dynamic torque force testing instruments, can simulate schedule use environment, the torsion to dental handpiece
Power is tested.
Background technique
Dental handpiece torque tester used in existing market is to be equipped with torque meter, this tooth by bearing on bracket
Section's mobile phone torque tester structure is more complicated, and manufacturing cost is expensive, and when use runs unstable, and process of measurement is more complicated,
It has a single function, and the dental handpiece of different model can not be shared.
Summary of the invention
In view of the deficiencies in the prior art, the present invention intends to provide a kind of dental handpiece dynamic torque force testing instrument, by applying
Add different pressure, the use environment of daily dental handpiece can be simulated, dynamic test is carried out to its torsion.
In order to realize above-mentioned technical proposal, the invention adopts the following technical scheme:
Dental handpiece dynamic torque force testing instrument, including pedestal, the pedestal is equipped with bracket and testboard, on the bracket
Equipped with can be along the testing jig that it is moved up and down；It is additionally provided with pressure gauge, torsiometer and connector, the pressure gauge and the test
Frame connection, the pressure test bar of the pressure gauge connect with one end of the connector；The torsiometer and the connector connect
It connects；The bottom of the torsiometer is equipped with prod.
It should be noted that the connector is made of upper connection cover and lower connection cover, the upper connection cover is equipped with and institute
The screw hole that pressure test bar matches is stated, the pressure test bar is rotatably connected in the screw hole；The internal screw thread of the upper connection cover
It is screwed on screw thread at lower connection cover, the torsiometer is fixed under the upper spiral shell between connection cover.
It should be noted that the surface of the upper connection cover is equipped with observation window, the reading of the observation window and the torsiometer
Book epitope is set accordingly.
It should be noted that the pressure test bar, the prod and dental handpiece head are coaxially disposed.
It should be noted that the testing jig includes that fixed frame and slide post form, the slide post is connected to described solid
Determine in the aperture on frame.
It should be noted that being additionally provided with rotational speed detector, the rotational speed detector is set to the side of the testboard.
The beneficial effects of the invention are that structure is simple, easy to use, manufacturing cost is cheap, and precision is high, for different shaped
Number dental handpiece can be carried out measuring.
In addition, key to the invention is that dynamic torsional test may be implemented, dental handpiece in actual use, with tooth
The dynamics difference that tooth contact or doctor use can all generate different resistances, and traditional dental handpiece torsional test can not mould
Intend this state, in other words, existing dental handpiece torsional test assumes that the premise for not having any resistance in an ideal
Under torsional test, can not learn after by resistance in this way, dental handpiece is in the torque value of different revolving speeds.And it is of the invention
It exactly can solve the technical problem, dental handpiece can be applied when testing torsion centainly by the pressure gauge of setting
Pressure, the revolving speed that is declined of dental handpiece after pressure is applied by tachymeter observable, then the revolving speed is observed by torsiometer
Generated torsion.
