Machining equipment with tension testing function for special-shaped lifting lug

Abstract

The invention discloses machining equipment with a tension testing function for a special-shaped lifting lug, which relates to the technical field of machining and detection of special-shaped components, in particular to a workbench, a lead screw tension mechanism, a connecting rod transmission mechanism, a pull rod clamping mechanism and an output end. One side of theworkbench is provided with a control end. According to the machining equipment with the tension testing function for the special-shaped lifting lug, by arranging the pull rod clamping mechanism, the problems that in the background technology, an existing tension testing mechanism is complex in operation of connecting clamping points of a to-be-detected material and depends on manual positioning are perfectly solved; a user drives the bayonet lock to rotate around the lug shaft by rotating the adjusting handle, so that the locking arm on one side of the bottom end of the bayonet lock locks the end face of the base plate, meanwhile, the eccentric block rotates under the transmission of the screw rod, and the lug part of the to-be-detected material is positioned and clamped through the output end on one side of the top end of the eccentric block, so that the clamping is stable while the operation is simple and convenient; and meanwhile, a centering effect on to-be-detected materials which are symmetric about a vertical symmetric axis is achieved.

Description

technical field [0001] The invention relates to the technical field of processing and testing of special-shaped components, in particular to a processing device with special-shaped lifting lugs with the function of tensile testing. Background technique [0002] Lifting lug is the force-bearing component installed on the equipment for lifting; the lifting lug is an important connecting part in equipment hoisting, which is directly related to the safety of large-scale equipment hoisting. Among many conveyor accessories, lifting lug is the It is an indispensable part in the operation. It is the main lifting point structure, so it requires good load-bearing capacity and stability. The strength requirements of its own strength and equipment connection. [0003] The common problems of the existing lifting lug processing and testing equipment are: in order to ensure the safety of hoisting, the design and production of the lifting lug adheres to the principle of no deformation of t...

Problems solved by technology

[0003] The common problems of the existing lifting lug processing and testing equipment are: in order to ensure the safety of hoisting, the design and production of the lifting lug adheres to the principle of no deformation of twice the working load, and the principle of carrying four times the load without breaking; and the lifting lug should have enough Rigidity and stability, with anti-fatigue and impact resistance performance; however, the current mainstream lifting lug testing equipment in the market does not have the actual processing environment to simulate the force on both ends of the lifting lug in the actual use, and the clamping and fixing operation of the material to be tested Complicated and low in applicability, it is impossible to ensure that the stress point of the material to be tested is located at its axisymmetric center, which affects the accuracy of the experimental results
