Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of frock clamp, in particular to a frock clamp for torsion shaft test. BACKGROUND

[0002] In mechanical manufacturing, torsion shafts are widely used in various transmission and drive systems. By testing the torsion shaft through frock clamp, the torque transmission capacity and fatigue life can be evaluated, providing reliable data support for mechanical design and manufacturing.

[0003] For example, the existing technology represented by application No. CN202022649995.8 mainly includes a clamp base plate and a clamp cover plate. The bottom of the clamp base plate is fixed with a limiting groove with a circular cross section. A drag plate is fixed at the bottom of the limiting groove, and the central axis of the drag plate coincides with a diameter of the limiting groove. The clamp cover plate is hingedly fixed to one side of the clamp base plate. The other side of the clamp cover plate is provided with a plurality of buckles. The other side of the clamp base plate is provided with a plurality of clamping grooves matched with the buckles. A plurality of water inlet holes are formed in the clamp base plate and the clamp cover plate. A positioning pedal is hingedly fixed to one side of the bottom of the clamp base plate. The molybdenum rod rubber mold clamp has simple structure and novel design, which is convenient for shaping the rubber mold, preventing complete deformation of the rubber mold during transportation, improving the processing precision of the molybdenum rod, and facilitating the fixation of the rubber mold to improve the assembly efficiency. The current widely used test method is to load the rubber rod into the bridge pipe through cold loading technology for performance test. However, this process not only takes a long time, but also consumes a lot of materials. The main disadvantage of the existing technology is the complexity of the cold loading process, which directly leads to a significant reduction in test efficiency.

[0004] In addition, once the rubber rod is cold-loaded into the bridge pipe, it can only be used to perform a specific type of test once. This results in the valuable test materials such as the bridge pipe and the rubber rod often cannot be reused after the test is completed, further exacerbating the problem of material waste. In order to solve this thorny problem, the present application proposes an innovative frock clamp for measuring the load-bearing performance of rubber rods. The design of the frock clamp aims to significantly improve the test efficiency and greatly reduce the waste of materials.

[0005] In use, it is found that the existing frock clamp can only be used to perform a specific type of test once, and the clamp cannot be reused after use, resulting in waste of materials. It is not convenient to realize torsion test of multiple rubber rods, so there is an urgent need for a frock clamp for torsion shaft test. UTILITY MODEL CONTENTS
