One end of a hydraulic oil cylinder of the device is connected with a hydraulic oil storage tank through a first one-way throttle valve, another end of the hydraulic oil cylinder is connected with the hydraulic oil storage tank through a second one-way throttle valve, a front end of the hydraulic oil cylinder is connected with the window opening machine through a connector, the window opening machine is connected with a pull and push dynamometer, manual regulation switches are arranged at the first one-way throttle valve and the second one-way throttle valve, the hydraulic oil cylinder is provided with two pressure sensors, and each pressure sensor is provided with an LED digital display. By utilizing the hydraulic mechanism, the problems of single method and low efficiency of moment tests at present due to the abraded mechanical structure caused by carrying weights are solved; the two-way test can be realized, the testing efficiency can be doubled, the load state can be displayed in real time, the throttle valves are adjustable, the pressure to be detected can be input manually, and the actual data is fed back in digital mode, thereby carrying out the correction and detection of the pressure automatically, and the performance evaluation device has convenient installation and disassembly.
Description
Technical field
The utility model relates to a kind of device for electric window-opening machine performance evaluation.
Background technology
Window opener uses a dead lift counterweight without Special testing device at present, the physical construction serious wear, and the test moment mode is single, inefficiency.
Summary of the invention
In order to overcome known window opener device for evaluating performance without Special testing device, need that a dead lift counterweight, physical construction serious wear, test moment mode are single, the defective of inefficiency, the utility model provides a kind of window opener device for evaluating performance, it is not easy to wear that this window opener device for evaluating performance does not need to carry counterweight, physical construction, can realize two-way test, efficient is high.
The technical scheme that its technical matters that solves the utility model adopts is: this window opener device for evaluating performance comprises the hydraulic oil storage box, hydraulic jack one end links to each other with the hydraulic oil storage box by the first one-way throttle valve, the hydraulic jack other end links to each other with the hydraulic oil storage box by the second one-way throttle valve, the hydraulic jack front end links to each other with window opener by joint, window opener links to each other with pull and push dynamometer, the first one-way throttle valve and the second one-way throttle valve place are equipped with the manual adjustments switch, the hydraulic jack place is equipped with two pressure transducers, pressure transducer band LED digital indicator.
Hydraulic principle relies on the static pressure of liquid medium in certain machinery, electronic system, finish overstocking, transmit, amplifying of energy, realizes light and handyization of mechanical function, scientific, maximization.1, hydraulicdriven various element can be arranged as required easily and flexibly.2, lightweight, volume is little, motional inertia is little, reaction velocity is fast.3, handle control conveniently, can realize large-scale stepless speed regulation (speed adjustable range reaches 2000:1).4, can automatically realize overload protection.5, generally adopt mineral oil as actuating medium, but relative motion face lubricating by oneself, long service life.6, be easy to realize rectilinear motion.7, be easy to realize the robotization of machine, after adopting electric liquid to jointly control, not only can realize the automatic control process of higher degree, and can realize remote control.
Advantage of the present utility model: use hydraulic mechanism, solves present because the carrying counterweight, physical construction is worn and torn, and the test moment mode is single, the problem of the links such as inefficiency.Realize the detection of mechanical-hydraulic structure, can realize two-way test truly.Present testing efficiency can be promoted one times.Realize the miniaturization of window opener testing apparatus, portability, economization, non-maintainingization.The inner SELF TEST of window opener MODE trace routine can detect window opener in any production process.Really accomplish self check, mutually inspection such as patrols and examines at the test mode.
The manual adjustments switch is installed at the one-way throttle valve place, and configuration digital indicator in hydraulic jack place shows loaded-up condition in real time, and the adjustable throttling valve is realized manually input pressure to be detected, and digital feedback goes out real data, thereby automatically carries out correct detection pressure.Easy installation and removal.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the present utility model.
Fig. 2 is the hydraulic jack structural representation among Fig. 1.
Among the figure: 1. the first one-way throttle valve, 2. the second one-way throttle valve, 3. hydraulic oil storage box, 4. HSGK02-40/25E * 500 type hydraulic jacks, 5. junction on the window opener, 6. window opener, 7. junction under the window opener, 8. pull and push dynamometer, 9. joint, 10. digital display type pressure transducer, 11. digital display type pressure transducers.
Embodiment
In Fig. 1 and Fig. 2, this window opener device for evaluating performance comprises hydraulic oil storage box 3, hydraulic jack 4 one ends link to each other with hydraulic oil storage box 3 by the first one-way throttle valve 1, hydraulic jack 4 other ends link to each other with hydraulic oil storage box 3 by the second one-way throttle valve 2, hydraulic jack 4 front ends link to each other with window opener 6 by joint 9, and window opener 6 links to each other with pull and push dynamometer 8.
The first one-way throttle valve 1 and the second one-way throttle valve 2 places are equipped with the manual adjustments switch.Hydraulic jack 4 places are equipped with two high- precision pressure sensors 10,11, two pressure transducers 10,11 band LED digital indicators.
When window opener 6 is connected with hydraulic jack 4.Can realize the test of Bidirectional pulling pulling force.The concrete operations way is as follows: when window opener 6 goes out stroke, promote the piston rod of hydraulic jack 4, hydraulic oil is discharged smoothly from the first one-way throttle valve 1.At this moment because the reverse throttling function of the second one-way throttle valve 2 can make window opener 6 in the situation that certain its thrust of resistance checking is arranged.
When window opener 6 during according to its its extreme limit of travel of intrinsic stroke motion, under the effect of controller, begin to carry out the opposite direction motion.This moment is because the principle of the mutually reverse throttling of the first one-way throttle valve 1 and the second one-way throttle valve 2, equal resistance when window opener 6 still can be subject to pushing away hydraulic jack 4 with it in the middle of the process of " returning ", with this in this way repeatedly motion, reach the purpose of test window opener Bidirectional pulling pulling force mechanical property.In the middle of this process, according to the test push-pull effort of the differential relationship dP=ρ (XdxYdy+Zdz) of pressure and the mass force of liquid internal=ρ (0*dx+0*dy+gdz)=when ρ gdz can calculate window opener 6 actual motion, thereby really realize the moment feedback of setting value and actual value.Reach the purpose of checking window opener 6 performances.
