The invention discloses a multi-torque integrated loading device for spline hub detection equipment. The multi-torque integrated loading device comprises a working table, a test lever assembly, torsion loading assemblies and a swing loading assembly, The test lever assembly comprises a test lever, a spline shaft cushion block, a universal ball, a test lever lower limiting block, a torsion hydraulic buffer and a swing hydraulic buffer, and is used for transmitting a torsion moment and a swing moment; the two torsion loading assemblies comprise torsion air cylinders and torsion air cylinder mounting seats and are used for generating a force required by the torsion moment; and the swing loading assembly comprises a swing air cylinder and a swing air cylinder mounting seat and is used for generating the force needed by the swing torque. The device has the beneficial effects that the integration of torsion moment loading and swinging moment loading is realized, and the automation degree of detection is improved; the air cylinder is used for loading the detection torque so that the detection repetition precision is improved; and an operator does not participate in the moment loading process so that the safety of the detection process is improved.

Description

technical field [0001] The invention specifically relates to a moment loading device for testing the bonding strength of the center spline of an aluminum alloy wheel hub and the outer layer of aluminum cladding, especially an integrated loading device capable of applying torsional or swinging moments to the hub spline. Background technique [0002] The center spline of the aluminum alloy spline hub is made of steel, and the outer layer of aluminum is gravity casted. This type of hub mainly detects whether the spline part and the outer layer of aluminum are tightly combined. The detection method is to apply a fixed periodic load to the splines of the hub through a special rocker with splines and observe whether there is a gap at the joint between the splines and the aluminum cladding. [0003] At present, this detection method mainly relies on manual detection. Three workers cooperate with each other. Two people press the wheel hub to be tested, and the other person uses a sp...

Problems solved by technology

[0003] At present, this detection method mainly relies on manual detection. Three workers cooperate with each other. Two people press the wheel hub to be tested, and the other person uses a special hand-operated measuring rod with splines. Depending on the type of wheel hub, a swinging moment of 50N·M or 200N·M torsion torque, visual inspection of splines and aluminum-clad joints, two kinds of torque loading methods need to use different hand-cranked measuring rods, and the applied torque is controlled by the worker to control the magnitude of the force arm and force, so there is a detection Problems such as low repeatability, time-consuming and labor-intensive, and low detection efficiency
