In one embodiment, the mounting bracket 1 includes one or more support blocks spaced apart along the axial direction of the drive shaft 3, on which the drive shaft 3 is rotatably supported.
The mounting frame 1 may further comprise a base plate 11, and the springs 5 and the respective support blocks are disposed on the base plate 11.
Optionally, support blocks are respectively disposed on two sides of the pressing arm 4, and the support blocks on two sides of the pressing arm 4 are configured to axially limit the transmission shaft 3 on the mounting frame 1.

In one embodiment, the torsion detecting device further comprises a sensing element 6 for detecting whether the pressing arm 4 rotates to a preset angle position, wherein the sensing element 6 may be a contact switch or other elements.
In fig. 1 the sensor element 6 is shown mounted on a support 16, which support 16 is fixed to the mounting 1. When the product 8 to be tested drives the transmission shaft 3 to drive the pressing arm 4 to rotate to the preset angle position towards the spring 5, the sensing element 6 is triggered, and when the pressing arm 4 rotates to the preset angle position, the spring 5 has a certain compression amount, so that the sensing element 6 is triggered to indicate that the torsion of the product 8 to be tested reaches the preset value.
The torsion detection device further comprises an upper computer, and the upper computer is set to be used for obtaining the power parameters of the product 8 to be detected and the trigger signal of the induction element 6 so as to determine whether the torsion of the product 8 to be detected reaches the standard or not.

Or, the detection element can directly detect the compression amount of the spring 5 and transmit the compression amount to an upper computer, and the torsion is determined according to the compression amount of the spring 5. Then, the power parameter of the product 8 to be tested can be further combined to determine whether the torque of the product 8 to be tested reaches the standard.
It should be noted that, the torsion magnitude corresponding to the compression amount of the spring can be calibrated in advance before the product is detected, specifically, the transmission shaft 3 can be connected with a torsion meter, when the transmission shaft 3 is driven to rotate by the torsion meter, the pressing arm 4 on the transmission shaft 3 compresses the spring 5, and the torsion meter displays the torsion magnitude, so that the torsion magnitude corresponding to the compression amount of the spring can be determined. Thus, when the product is actually detected, the torsion of the product can be determined according to the compression amount of the spring.
In an embodiment, the torsion detection apparatus further includes a base 2, and a product 8 to be detected is fixed on the base 2 for detection.
Specifically, the base 2 is provided with a clamp 7 for fixing a product 8 to be tested, and the clamp 7 includes clamp blocks 71 respectively arranged at two sides of the product 8 to be tested and a driving mechanism 72 for driving the clamp blocks 71 at two sides to move towards or away from each other. The driving mechanism 72 may be a cylinder or a screw mechanism, and is not limited herein.
Fig. 1 and 2 show that the base 2 is provided with a second guide rail 22, the second guide rail 22 is perpendicular to the axial direction of the transmission shaft 3, and the clamping blocks 71 on two sides of the product 8 to be tested are respectively movably arranged on the second guide rail 22. Fig. 2 shows that the clamping blocks 71 on the two sides of the product 8 to be tested are respectively and correspondingly provided with the driving mechanisms 72, when the driving mechanisms 72 on the two sides drive the corresponding clamping blocks 71 to move towards each other, the clamping blocks 71 on the two sides clamp the product 8 to be tested, so as to fix the product 8 to be tested on the base 2, and when the driving mechanisms 72 on the two sides drive the corresponding clamping blocks 71 to move away from each other, the product 8 to be tested is released, and the product 8 to be tested can be detached from the base 2.
In one embodiment, the mounting frame 1 is configured to move along the axial direction of the transmission shaft 3 with the transmission shaft 3 relative to the base 2, so that the transmission shaft 3 is connected with the output shaft 81 of the product 8 to be tested. As shown in fig. 1, the bottom plate 11 of the mounting bracket 1 is movably mounted on a first guide rail 21 of the base 2, the first guide rail 21 being parallel to the axial direction of the driving shaft 3. When the mounting frame 1 moves towards the product 8 to be tested along the axial direction of the transmission shaft 3, the transmission shaft 3 is in butt joint with the output shaft 81; when the mounting frame 1 moves away from the product 8 to be tested along the axial direction of the transmission shaft 3, the transmission shaft 3 is disconnected from the output shaft 81.
Optionally, the torsion detection device further includes a pushing mechanism 9, and the pushing mechanism 9 is configured to push the mounting frame 1 at a side of the mounting frame 1 away from the product 8 to be detected, so that the transmission shaft 3 remains connected to the output shaft 81.

When the handle 92 rotates in the opposite second direction, the link mechanism drives the pushing portion 91 to move away from the product 8 to be tested, and at this time, the mounting frame 1 can drive the transmission shaft 3 to be disconnected from the output shaft 81.
It will be appreciated that the pressing means 9 may be of various configurations, as long as it can press against the mounting frame 1 so that the transmission shaft 3 remains connected to the output shaft 81.
It will also be appreciated that the mounting frame 1 may be arranged to be fixed (i.e. to maintain the axial position of the drive shaft 3), in which case the pressing means 9 need not be provided, but rather the product to be tested is arranged to be axially movable to effect connection and disconnection with the drive shaft 3.
A specific process of detecting the product 8 to be detected by using the torsion detecting apparatus provided in the present application is described below according to an embodiment.
Placing a product 8 to be tested on the base 2, clamping the product 8 to be tested through the clamp 7 and fixing the product on the base 2, wherein in the process, an output shaft 81 of the product 8 to be tested is aligned with the axis of the transmission shaft 3;

the product 8 to be measured drives the transmission shaft 3 to rotate, the pressure arm 4 on the transmission shaft 3 rotates from the initial position to press the spring 5, and the spring 5 is gradually compressed. Wherein, when the spring 5 is compressed to a certain degree, the rotating speed of the transmission shaft 3 can be reduced;
when the compression amount of the spring 5 reaches a preset value, the sensing element 6 is triggered, and the upper computer judges whether the torsion of the product 8 to be detected reaches the standard or not according to the feedback of the sensing element 6 and the acquired power parameter of the product 8 to be detected.
Wherein, the program on the host computer can also calculate the compression amount of spring (or directly obtain the compression amount of spring 5 from the detecting element) according to the angle that transmission shaft 3 rotated to can show the torsion size of obtaining the product 8 that awaits measuring in real time.
The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modifications, equivalents and the like that are within the spirit and principle of the present application should be included in the scope of the present application.
