Description of drawings
Fig. 1 is an one-piece construction synoptic diagram of the present invention;
Fig. 2 is the synoptic diagram of motor-driven mechanism of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
The present invention adopts frequency control, drives toggle by clutch coupling and produce mechanical exciting, forces to vibration damper back and forth flexible acting to realize test purpose.Vibration damper upper end connects pull pressure sensor, detects the damping force value of vibration damper by TT﹠C system, judges whether vibration damper is qualified.
As shown in Figure 1, the present invention is the double dynamometer machine, is equipped with two and detects station on a testing table, can carry out the detection of two vibration dampers simultaneously.Simultaneously,, work alone because each principle of work that detects station is the same, so this dynamometer machine also can be reduced to single station dynamometer machine, below singly the present invention is introduced with regard to one of them structure and principle that detects station:
Talk about from power source, as shown in Figure 2, the present invention includes: a frequency converter case 1, control of conversion motor 2, the output terminal of variable-frequency motor 2 connects a crank base 5 by variable-speed motor 3, clutch coupling 4, the eccentric connecting rod 6 that connects on the crank base 5, connecting rod 6 upper ends connect a slide block 7, and slide block vertically is slidingly installed in the chute.Slide block 7 upper ends connect jig seat 8.The exciting stroke is by the decision of the stroke of slide block, for different exciting stroke requirements, slide block will have different strokes, and the stroke of slide block 7 is changed by adjusting the position of connecting rod 6 on crank base, therefore an adjusting slider is set on crank base 5 often connects connecting rod, and adjusting slider is fixed on the crank base by lock-screw; Perhaps on crank base 5, offer oblong hole, with connecting rod 7 by be bolted in the slotted hole also can, only bolt need be unclamped when adjusting connecting rod, mobile Kong Weizai is fastening to get final product.Other has a crank sensor 9, the rotating speed of induction crank mechanism and the displacement of slide block.
What directly link to each other with slide block 7 is jig seat 8, and a stretch oil cylinder 10 is installed in the bottom of jig seat 8, moves with the jig seat.The jig seat comprises two slide bars 11 and is supported on gland holding frame 12, vibration damper holding frame 13 between two slide bars.Before the test, stretch oil cylinder 10 stretches out top vibration damper 14 on the piston rod in advance according to the length of vibration damper, and vibration damper and gland 15 are held out against, and holding frame 13 clamps the tube portion of vibration damper; Jig seat 8 and vibration damper 14 move with toggle more then.
Above-mentioned introduction be electric drive part, the present invention also comprises the hydraulic-driven part, except above-mentioned stretch oil cylinder 10, also has one or two hoist cylinder 16, hoist cylinder 16 connects a hoisting cross beam 17, hoisting cross beam 17 is slidingly installed on the lifting column 18, and is locked on the lifting column by screw 19 after lifting puts in place.Hoisting cross beam is hung oneself and is established a tension-compression sensor 20, and the lower end of tension-compression sensor 20 links to each other with damper stem.According to the length and the stroke of vibration damper to be measured, start the height that hoist cylinder is adjusted hoisting cross beam, tension-compression sensor is linked to each other with vibration damper, damper stem is in the effective travel scope.Stretch oil cylinder and hoist cylinder are all by the oil pump station fuel feeding.
Installation and Debugging process in the work is: at first detect standard according to vibration damper and adjust the exciting stroke, the connecting rod that unclamps on the crank base is adjusted eccentric throw, up to reaching the stroke that detects code requirement.Adjust stretch oil cylinder 10 according to the length of detected vibration damper and the stroke of vibration damper then, hold out against gland with vibration damper till.Unclamp the trip bolt 19 on the hoisting cross beam at last, hoisting cross beam requires the midstroke of vibration damper is overlapped substantially with the exciting midstroke of multiple speed according to the vibration damper actual process, locks the trip bolt of hoisting cross beam again.During hoisting cross beam, should note two extreme positions of practical work piece, do not drawn badly or smash to guarantee pull pressure sensor.After the crossbeam locking, do not allow hoisting cross beam.
The present invention can carry out the double operation, promptly refer to: on same testing table, be equipped with two and detect station, two cover motor-driven mechanism, two cover crank linkage assemblys, two cover jig seats, two cover stretch oil cylinders, two tension-compression sensors, have only hoist cylinder, therefore the hoisting cross beam system can be shared one, can carry out the detection of two vibration dampers simultaneously on same testing table.
The present invention can carry out the multiple speed test, promptly refer to: the power value that clamping of vibration damper can be done a plurality of speed points detects, and detect the damping force value of vibration damper by TT﹠C system, mark out corresponding maximum and minimum damping force value, also can judge automatically whether its measured value is qualified according to predefined upper and lower ultimate damping power value, and the load-position diagram of the vibration damper that draws (P-S figure), speed characteristic curve (P-t figure) is shown on the indicator screen or printout.Can also be kept in the computing machine for calling at any time detecting data in addition.
