Description
Technical field
The present invention relates to the detecting instrument technical field.
Background technology
Vibroshock is the crux parts of automobile, and its life-span is related to using of whole vehicle body and takes advantage of manned member's comfortableness, in order to detect vibroshock serviceable life, a kind of detector must be arranged, in order to the practical working situation of simulation at road driving.
Summary of the invention
The object of the invention designs a double-action durability test instrument for shock-absorber exactly, is used for detecting the serviceable life at road driving process vibroshock.
The present invention includes fuselage, at the fixedly connected column of body upper; In fuselage, be provided with the underdrive motor, down moving subassembly, down moving connecting rod, worm and gear gear motor, on moving subassembly, on moving connecting rod, be in transmission connection between described underdrive motor and the following moving subassembly, the described lower end of moving connecting rod down is connected down the off-centre output axle head of moving subassembly, be in transmission connection between described worm and gear gear motor and the upward moving subassembly, the described output terminal of moving subassembly connects eccentric reel, and described lower end of moving connecting rod is connected on the eccentric reel; Arrange moving case subassembly on the column, fixedly connected locating rack and last holder assembly on last moving case subassembly, described lower end of moving case subassembly is connected with described upper end of moving connecting rod; Fuselage peripheral hardware below last moving case subassembly is put lower moving plate, fixedly connected holder assembly down on the lower moving plate, and described lower moving plate and the described upper end of moving connecting rod down interconnect.
The present invention is used for simulating vibroshock and is loaded on the car in the practical working situation of road driving, and tested vibroshock two ends are clamped in respectively on the upper and lower holder assembly, by excitation motion simultaneously up and down, vibroshock is strengthened long duration test under dynamically.Wherein go up exciting and significantly vibrate for the low frequency of simulating vehicle body, following exciting slightly vibrates for the high frequency of simulation wheel.According to the variation of vibroshock, evaluate its performance, use and research for applying unit.This test method is more fast, more economical than the road examination, is that vibroshock manufacturer and R﹠D institution grasp and control one of indispensable testing equipment of product quality.
Compact conformation of the present invention, convenient operating maintenance adopts programmable controller (PLC) control action mode, screen displaying test speed, number of times and test run state etc.When test number (TN) reached setting value, equipment can be realized auto stop.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Embodiment
As shown in Figure 1, fuselage 1 upper fixed connects column 2, and underdrive motor 3, moving subassembly 4, moving connecting rod 5, worm and gear gear motor 6, upward moving subassembly 7, last moving connecting rod 8 down down are set in the fuselage 1.
Be in transmission connection by driving-belt 9 between underdrive motor 3 and the following moving subassembly 4, the lower end of following moving connecting rod 5 is connected down the output terminal of the excentric shaft 4-1 of moving subassembly 4.
Be in transmission connection by driving-chain 16 between worm and gear gear motor 6 and the upward moving subassembly 7, upward the output terminal of moving subassembly 7 connects eccentric reel 15, and upward the lower end of moving connecting rod 8 is connected on the eccentric reel 15.
Arrange moving case subassembly 10 on the column 2, fixedly connected locating rack 11 and last holder assembly 12 on last moving case subassembly 10, upward the lower end of moving case subassembly 10 is connected with the upper end of last moving connecting rod 8.Fuselage 1 peripheral hardware below last moving case subassembly 10 is put lower moving plate 13, fixedly connected holder assembly 14 down on the lower moving plate 13, and lower moving plate 13 lower ends interconnect with the upper end of following moving connecting rod 5.
Last transmission is by horizontally-mounted worm gear pole gear motor 6, chain transmission 16, last moving subassembly 7 and go up moving case subassembly 10 etc. and form.During work, when eccentric reel 15 rotated, last holder assembly 12 and locating rack 11 in the drive on the moving case subassembly 10 pumped.
Underdrive is made up of underdrive motor 3, driving-belt 9, time moving subassembly 4, lower moving plate 13 and the following holder assembly 14 etc. of distribution fuselage both sides.Excentric shaft 4-1 under underdrive motor 3 drives by driving-belt 9 in the moving subassembly 4, holder assembly 14 pumps to make lower moving plate 13 reach down.
Before the test, at first that sample vibroshock clamping on the mount pad of testing machine both sides is good, set test number (TN), the test speed of determining by touch-screen, by programmable controller (PLC) control motor action, carry out the vibroshock double-acting endurance.
