Summary of the invention
The purpose of this utility model provides a kind of employing hydrostatic transmission loading and adjusts test space, has the complete machine structure connection and stablizes firm, stable drive, the two oil cylinder universal testing machines of noise frequency conversion type little and long service life.
For achieving the above object, the utility model is achieved through the following technical solutions.The two oil cylinder universal testing machines of frequency conversion type comprise base, entablature, sill, upper pillar stand, lower pillar stand, platform, test oil cylinder, piston, clamp device, setscrew nut, dynamometry indication mechanism, hydraulic control system and hoist cylinder, hoist cylinder are enclosed within the test oil cylinder, and piston cooperates with the hoist cylinder inwall, the top of piston and hoist cylinder contacts with the platform bottom, and hydraulic circuit is communicated with test oil cylinder and hoist cylinder respectively.
The two oil cylinder universal testing machines of described frequency conversion type, its upper pillar stand and entablature and platform are fastenedly connected by setscrew nut, lower pillar stand and sill and base are fastenedly connected by setscrew nut, pilot hole and lower pillar stand on the platform are slidingly matched, and pilot hole and upper pillar stand on the sill are slidingly matched.
The two oil cylinder universal testing machines of described frequency conversion type, its hydraulic control system comprises fuel tank, solenoid directional control valve I, solenoid directional control valve II, oil pump, motor and frequency converter, motor is connected with frequency converter, oil pump is connected with motor, and the fuel-displaced pipeline of oil pump is leaded up to solenoid directional control valve II and entered hoist cylinder, and another road enters test oil cylinder by solenoid directional control valve II and solenoid directional control valve I.
The utility model compared with prior art has the following advantages: (one) is owing to changed the method for existing adjustment test space, changes into pure hydrostatic transmission by pure mechanical drive, thereby makes complete machine stable drive, noiselessness; (2) be the method that has changed existing adjustment test space speed, adopt the frequency conversion mechanism controls, common electric machine connects the low discharge oil pump, speed by frequency converter is regulated, hoist cylinder, piston are in rising, when descending, and motor, oil pump run up, and the speed of adjusting test space is improved greatly, motor pump low-speed running when applying test power, the slowly requirement of running of low speed when having guaranteed again to apply test power; (3) be to form a framed structure because upper pillar stand and entablature and platform are fastenedly connected by setscrew nut, lower pillar stand and sill and base are fastenedly connected by setscrew nut and form another framed structure, changed between former upper pillar stand and entablature and lower pillar stand and the base because the space that pure mechanically operated needs leave, each parts connects compact, integral rigidity is good, the fastness that complete machine is connected improves greatly, loading work is the effect between two framed structures, make loading seem very steady, improve the serviceable life of complete machine greatly.
