Abstract
A center swivel joint endurance test device belongs to a construction mechanical part test device. A motor of the endurance test device is connected with a hydraulic pump; an output end of the hydraulic pump is connected with an oil cylinder through a safety valve; the hydraulic pump is connected with a radial pressurization cylinder via a pressure reducing valve and a two-position two-way electromagnetic directional valve and is also connected with a rod end of a hydraulic cylinder via a three-position four-way electromagnetic directional valve and a first throttle valve, and a rodless end of the hydraulic cylinder is connected with an oil tank through the three-position four-way electromagnetic directional valve; a piston rod of the hydraulic cylinder is connected with a center swivel joint test tool; travel detection switches are arranged at two ends of the center swivel joint test tool; and a center swivel joint is arranged on the center swivel joint test tool. The center swivel joint endurance test device has the advantages that a stator and a sleeve of the center swivel joint can perform automatic and repeated rotational movement in the positive and the inverse directions, the radial pressurization cylinder can load adjustable lateral force on the center swivel joint, and the test results are the same with the actual working conditions of the center swivel joint.
Description
Technical field
The utility model relates to a kind of engineering machinery component test device, particularly a kind of centre revolving joint durability test device.
Background technology
Centre revolving joint is in process of the test, and the positive and negative reciprocal rotation that its sleeve and stator need not stop needs sleeve is loaded side force simultaneously, to examine its permanance, pair test unit that centre revolving joint carries out endurancing is not arranged as yet at present.
The utility model content
The purpose of this utility model is to provide a kind of: realize centre revolving joint sleeve and the positive and negative reciprocal rotation of stator, simultaneously sleeve is loaded the centre revolving joint durability test device that side force and side force can be regulated.
The object of the present invention is achieved like this: this durability test device comprises: motor, hydraulic pump, safety valve, the 3-position 4-way solenoid directional control valve, the first throttle valve, second throttling valve, reduction valve, the 2/2-way solenoid directional control valve, pressurized cylinder radially, hydraulic cylinder, centre revolving joint test frock, stroke detection switch and centre revolving joint, motor is connected with hydraulic pump, the hydraulic pressure delivery side of pump connects oil cylinder by safety valve, hydraulic pump is connected with pressurized cylinder radially by reduction valve and 2/2-way solenoid directional control valve, hydraulic pump also is connected with the rod end of hydraulic cylinder with the first throttle valve by the 3-position 4-way solenoid directional control valve, the rear end of hydraulic cylinder is by 3-position 4-way solenoid directional control valve connected tank, the piston rod of hydraulic cylinder is connected with centre revolving joint test frock, two ends in centre revolving joint test frock all have the stroke detection switch, on centre revolving joint test frock centre revolving joint are arranged.
Beneficial effect, owing to adopted such scheme, when the electromagnet YA2 of 3-position 4-way solenoid directional control valve energising, the 3-position 4-way solenoid directional control valve commutates to right position, hydraulic cylinder stretches out, make the rotation of centre revolving joint stator and sleeve, when the hydraulic cylinder motion reaches certain position, the stroke detection switch detects its position, the electromagnet YA1 energising of control 3-position 4-way solenoid directional control valve, and the 3-position 4-way solenoid directional control valve commutates to position, a left side, the hydraulic cylinder withdrawal, centre revolving joint stator and sleeve are selected round about, and when hydraulic cylinder was withdrawn into certain position, the stroke detection switch detected its position, the electromagnet YA2 energising of control 3-position 4-way solenoid directional control valve, the 3-position 4-way solenoid directional control valve commutates to right position again, and hydraulic cylinder stretches out, and runs so forth.The speed of regulating the first throttle valve and second throttling valve adjustment hydraulic cylinder withdrawal and stretching out is adjusted centre revolving joint stator and the counterrotating speed of sleeve.When the electromagnet YA3 of 2/2-way solenoid directional control valve energising, radially pressurized cylinder applies side force to the sleeve of both sides centre revolving joint, regulates the side force of side direction pressurized cylinder by regulating reduction valve.
Realize the positive and negative reciprocal rotation of centre revolving joint sleeve and stator, can regulate sleeve loading side force and side force simultaneously, reached purpose of the present invention.
Advantage: the positive and negative both direction between centre revolving joint stator and the sleeve rotatablely moves automatically repeatedly, and radially pressurized cylinder can load side force and side force can be regulated to centre revolving joint, and is identical with the actual condition of centre revolving joint.
