Description

Technical Field

[0001] The utility model relates to the technical field of spring pressure testing, in particular to a compression spring force measuring tool. Background Art

[0002] A spring is a mechanical part that uses elasticity to work.

[0003] At present, during the test of the spring force measuring device, when the spring undergoes elastic deformation along the axial direction, the spring often undergoes deformation along the lateral direction. If the spring undergoes lateral deformation, it will affect the elastic performance of the spring, thereby causing errors in the test data and inaccurate test results. Utility Model Content

[0011] Preferably, the distance between the two carriers is adapted to the force plate so that the force plate can move downward therethrough.

[0012] Preferably, the force plate further includes a force measuring element for detecting the pressure exerted on the force plate.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The utility model can limit the placed compression spring through the above-mentioned two placement grooves to ensure that the compression spring can only be deformed in the axial direction; and the above-mentioned guide needle column can be inserted into the axial inner cavity of the compression spring when moving downward, so as to further ensure that the compression spring can only be deformed in the axial direction and will not be displaced in the lateral direction.
