Description
Technical field
The utility model belongs to dental care technical field, is related to a kind of root canal file, specifically, is related to a kind of root canal file
Torsion-testing apparatus.
Background technology
When producing root canal file, root canal file file body and the assembling of root canal file handle are an essential procedures.
If assembling is improper between root canal file file body and root canal file handle, root canal file handle and root pipe during doctor's use
File file body is easy for coming off, this just brings unnecessary trouble to root canal, and it is mood not only to influence whether patient,
Therapeutic effect can also be directly influenced.
Therefore, all the time, insider and numerous medical personnels are working hard therefore.Attempt to torque
Test device tests the root canal file that every assembles, and reaches the value of setting as the mark of certified products using torque.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art or defects, provide a kind of root canal file torque measuring trial assembly
It puts.A kind of test fixture for detecting root canal file file body and handle assembling fastness is become, to examine root canal file file body and root
Whether the assembling between pipe file handle is secured, it is ensured that the normal use of doctor and the tooth treatment effect of patient.
To achieve these goals, the utility model employs following technical solution：
A kind of root canal file torsion-testing apparatus, which is characterized in that including one and above fixed module and torque measurement mould
Block；
Each fixed module includes one piece of vertical plate, one piece of fixed plate, is embedded and is indulged in the vertical plate and fixed plate
Two to both ends and above inserts, each inserts are equipped with the endoporus filed external footpath with root canal file and matched；
The torque measurement module includes measurement head, and the measurement head is equipped with and the matched survey of root canal file handle
Prospect hole, the root canal file handle positioning are arranged in the instrument connection of the measurement head.
Above-mentioned root canal file torsion-testing apparatus, wherein,
The measurement head is equipped with torque sensor.
The first test surfaces in the measurement head instrument connection are fitted closely with the second test surfaces on the root canal file handle.
Compared with prior art, the utility model has the advantages that：
The detection efficiency of root canal file is greatly improved, product quality is detected with high reproducibility, uniformity, is greatly decreased
Cost of labor.Especially it is that full inspection is carried out to root canal file, ensure that the stability for the product that dispatches from the factory.

Matched endoporus 7a；
Torque measurement module includes measurement head 5, and measurement head 5 is equipped with and 4 matched instrument connection 5a of root canal file handle, root
The pipe file positioning of handle 4 is arranged in the instrument connection 5a of measurement head 5.
As shown in fig. 3 to 7, the first test surfaces 5b in the instrument connection 5a of measurement head 5 is surveyed with second on root canal file handle 4
Examination face 4a is fitted closely.
As shown in Figure 1, 2, measurement head 5 is equipped with torque sensor 6.
One embodiment of the utility model root canal file torsion-testing apparatus is shown in Fig. 1.As shown in Figure 1, by root pipe
The file body 8 of file is partially placed into the endoporus 7a for inlaying 7, and clamping then is fixed with fixed module；
The handle 4 of root canal file is put into measurement head 5, is ensured in the second test surfaces 4a and the measurement head 5 on root canal file handle 4
The first test surfaces 5b fit closely, after placement, turn measurement head 5 measures torque value.So as to complete the torque of root canal file
Test.
Embodiment 1：Device as shown in Figure 1 is made, torsion measurement head 5 manually is carried out and completes torsion-testing.
Embodiment 2：On the basis of device as shown in Figure 1, driving equipment is added in measurement head 5, realizes that automation is surveyed
Examination.
As a kind of preferred embodiment of above-mentioned technical proposal, torsion-testing is carried out to root canal file using embodiment 2.
Above example is only for illustration of the utility model rather than limitation to the utility model, related technical field
