Detailed Implementation

[0021] Example 1

[0022] refer to Figures 1-3The utility model provides a kind of spring force detection tool of annular spring sheet, including detection base 1 and detection dynamic plate 2, in the embodiment, spring force detection tool further includes detection table 6, detection base 1 is fixedly arranged (preferably, by screw connection) on the top of detection table 6, detection table 6 is equipped with the active space for the activity of detection dynamic plate 2.

[0023] Detection base 1 is equipped with several fixed structures, for fixing the position of several uniform intervals on the circumference of annular spring sheet 3, detection dynamic plate 2 is connected with the loading mechanism of spring force tensile test equipment, and detection dynamic plate 2 is equipped with several force exertion structures, for exerting tension or pressure on the position of several uniform intervals on the circumference of annular spring sheet 3. That is to say, each fixed position of annular spring sheet 3 is arranged on the circumference of uniform interval, and each force position of annular spring sheet 3 is also arranged on the circumference of uniform interval during detection, so that the force of annular spring sheet 3 is more uniform when deforming, and the accuracy of detection result is improved.

[0024] In the embodiment, any one fixed position of annular spring sheet 3 is located at the intermediate position of adjacent two force positions. In a popular way, each fixed position of annular spring sheet 3 and each force position are crossed and spaced, and the interval distance is equal. So setting, the force uniformity of annular spring sheet 3 when deforming can be further improved, so as to further improve the accuracy of detection result.

[0025] The specific fixing mode of fixed structure and the specific force exertion mode of force exertion structure in the embodiment will be introduced below, and in the embodiment, annular spring sheet 3 is located between detection base 1 and detection dynamic plate 2, the force exertion structure includes connecting screw 4 and connecting threaded hole 201 on detection dynamic plate 2, annular spring sheet 3 is provided with connecting through hole corresponding to connecting threaded hole 201, connecting screw 4 is installed in connecting through hole and connecting threaded hole 201.

In actual application, after connecting screw 4 and fixing screw 5 are fixed, detection dynamic plate 2 moves downward to exert tension on annular spring sheet 3, so that it deforms.

[0026] On the basis of the above, it is easy to understand that first avoiding through hole 102 should be provided on detection base 1 at the position corresponding to connecting screw 4, and second avoiding through hole 202 should be provided on detection dynamic plate 2 at the position corresponding to fixing screw 5, so as to avoid interference.

[0027] In addition, it is worth mentioning that for the annular spring sheet 3 in the brake, a plurality of evenly spaced through holes are usually arranged as mounting holes in the circumferential direction, so in actual application, only a part of the through holes are selected as the connecting through holes, and the other part is selected as the fixed through holes. For example, the annular spring sheet 3 is evenly spaced in the circumferential direction and has six through holes, and any three evenly spaced through holes are selected as the connecting through holes, and the remaining three through holes are selected as the fixed through holes.

[0028] It is easy to understand that in other embodiments, the specific fixing mode of the fixing structure and the specific force applying mode of the force applying structure can also be other structures, for example, both are clamping jaws, the clamping jaws of the fixing structure are clamped and fixed from the outside of the annular spring sheet 3, and the clamping jaws of the force applying structure are clamped and fixed from the inside of the annular spring sheet 3. In addition, in other embodiments, one of the fixing structure and the force applying structure can also be selected as a screw connection mode, and the other can be selected as another mode.
