Problems solved by technology

[0005] During the process of pulling the buckle out of the through hole in the sheet metal part by the tensile testing machine, the direction of the force of the tensile testing machine may not be parallel to the center line of the through hole in the sheet metal part, and the force of the tensile testing machine is vertical The component force of the center line of the through hole in the sheet metal part is not used to overcome the locking force of the buckle. At this time, the force of the tensile testing machine is different from the locking force of the buckle, and the measurement result of the locking force is not accurate.

Abstract

The invention provides a testing tool, a testing device and a testing method for the locking force of a buckle, and belongs to the field of measurement. The testing tool comprises a base, a strip-shaped supporting block, at least two fixing shafts and at least two bearings. The base is a box body with an opening in one end, a tension tester connecting structure is arranged at one end, opposite tothe opening, of the box body, and a containing cavity communicated with the opening is formed in the box body; the at least two fixing shafts are parallel to each other and are fixed in the containingcavity along the extending direction of the opening; the at least two bearings are in one-to-one correspondence with the at least two fixing shafts, and each bearing is arranged outside the corresponding fixing shaft in a sleeving manner; the first end of the strip-shaped supporting block is slidably arranged on the at least two bearings, the middle of the strip-shaped supporting block is inserted into the opening, and the second end of the strip-shaped supporting block is provided with a tension sensor connecting structure; an upper buckle is fixed to the base, a lower buckle is fixed to thefirst end of the strip-shaped supporting block, and the strip-shaped supporting block is located between the upper buckle and the at least two bearings. According to the invention, the accuracy can be improved.

Description

technical field [0001] The present disclosure relates to the field of measurement, in particular to a testing tool, testing device and testing method for buckle locking force. Background technique [0002] A buckle is a mechanism for the embedded connection or integral locking of one part to another part, usually made of a material with certain flexibility. The biggest feature of the buckle connection is that it is easy to install and disassemble, and can be disassembled without tools, so it is widely used. [0003] In the related technology, usually the buckle is clamped in the through hole in the sheet metal part first, then the sheet metal part is fixed on the tensile testing machine, and then the telescopic end of the tensile testing machine is fixedly connected with the buckle, and finally the tensile test is used to The machine pulls the buckle out of the through hole in the sheet metal part, and measures the force of the tensile testing machine during the process as ...
