Abstract
The invention provides a curve lifting, clamping and releasing device for detecting buggy shocking performance. The device comprises a power transmission device, a curve transmission device and a clamping and releasing device. The power transmission device is transmitted to the curve transmission device through a decelerator and a chain by a servo motor; meanwhile, the clamping and releasing device is arranged on a curve guide rail to realize the clamping before lifting a tested buggy and the releasing after the lifting. The device is suitable for detecting the buggy shocking performance, can accurately control the lifting height of the tested buggy in the actual measurement so as to obtain the accurate collision speed and impacting energy. The device has the characteristics of improved test accuracy and convenient and rapid repetitive operation.
Description
Technical field
The present invention relates to a kind of curve lifting, clamping and releasing means, particularly a kind of moving curve lifting, clamping and releasing means of Performance Detection of hitting of perambulator that be used for.This device belongs to perambulator security performance detection technique field.
Technical background
In the perambulator detection technique, impact test is a vital test item.Perambulator was moving in the past hits in the performance detection apparatus, for the bigger defective of controllability existence of impact velocity and Impact energy, draws tested perambulator to a certain height by hand, and the repeatable accuracy of influence test has limited the integral body lifting of perambulator security performance detection technique.
Summary of the invention
The object of the invention is to the problem in the perambulator impact test process; A kind of moving curve lifting, clamping and releasing means of Performance Detection of hitting of perambulator that be used for is provided; Obtain accurate impact velocity and Impact energy with this, realized automatic clamping, accurately lifting, the stable repeated test that discharges in the perambulator crash tests.
For achieving the above object, design of the present invention is:
Hit in the Performance Detection process in that perambulator is moving, adopt clamping and the tested perambulator of releasing means clamping, the control servomotor also accurately is promoted to the appointment hoisting depth with tested perambulator along the curvilinear guide operation.After clamping and releasing means were realized discharging automatically then, curved surface is free to roll downwards tested perambulator along setting under the guiding of guiding device.
According to the foregoing invention design, the present invention adopts following technical proposals:
A kind ofly be used for that perambulator is moving to hit curve lifting, clamping and the releasing means of Performance Detection, comprise actuating unit, curve gearing and clamping and releasing means.
The structure of said actuating unit is: be installed in a servomotor and a speed reduction unit on the fixed support and drive a drive sprocket, this drive sprocket is through rack-mount drive sprocket of driving chain transmission;
The structure of said curve gearing is: a driven sprocket is installed on a support, and said drive sprocket is through the said driven sprocket of long gypsy chain bar transmission; Said long gypsy chain bar makes this long gypsy chain bar parallel all the time with tested perambulator operation curved surface by the curved shape of a plurality of stretching pulley tensionings;
The structure of said clamping and releasing means: a cylinder is fixedly connected with said long gypsy chain bar; This cylinder and a curvilinear guide cunning are joined; The piston rod of this cylinder is fixedly connected with a clamping rod, said curvilinear guide and tested perambulator operation curved surface arranged parallel.
The present invention has following conspicuous substantive outstanding feature and remarkable advantage compared with prior art:
(1) the present invention has used clamping and releasing means; Adopt telescopic cylinder; The elongation that promotes the clamping rod can realize clamping and the release to tested perambulator with withdrawal; Adopt guide rail that clamping and releasing means sliding guide can be provided, utilize particularly baby walker design feature of perambulator, can realize automatic clamping or release it.Beneficial effect is to have realized the conveniently clamping lifting and unloading release of tested perambulator saved time, and can be used for repeated test.
(2) the present invention has used servomotor and the chain drive in the actuating unit, and the direct regulation and control servomotor rotates revolution and angle, makes tested perambulator obtain accurate hoisting depth.
(3) the present invention has used the curve gearing; Realized that through the stretching pulley effect driving chain is parallel all the time with tested perambulator operation curved surface; This design makes that the operation of tested perambulator is mild, and curved surface is used for quickening, and the plane makes impact velocity direction level; The tested perambulator of fitting moves the characteristics of curved surface, makes clamping and releasing means when curve promotes, can keep clamp position originally.
Description of drawings
Fig. 1 is a kind of moving curve lifting, clamping and releasing means structural representation of Performance Detection of hitting of perambulator that be used for that the present invention combines the baby walker instance.
Embodiment
An instance accompanying drawings of the present invention is following: referring to Fig. 1, be used for originally that perambulator is moving to hit curve lifting, clamping and the releasing means of Performance Detection, comprise actuating unit, curve gearing and clamping and releasing means.The structure of said actuating unit is: be installed in a servomotor and a speed reduction unit on the fixed support and drive a drive sprocket, this drive sprocket is through rack-mount drive sprocket of driving chain transmission; The structure of said curve gearing is: a driven sprocket is installed on a support, and said drive sprocket is through the said driven sprocket of long gypsy chain bar transmission; Said long gypsy chain bar makes this long gypsy chain bar parallel all the time with tested perambulator operation curved surface by the curved shape of a plurality of stretching pulley tensionings;
When concrete operations; The control servomotor, the transmission through chain 23,31 moves to zero-bit with clamping and releasing means 1, and (move the anti-secondary impact device that hits the Performance Detection comprehensive test machine through perambulator, tested perambulator initial position is fixed; Can be provided with and be zero-bit here); Drive cylinder 11 and promote 12 elongations of clampings rod and realize the holding of tested perambulator, the control servomotor is after the transmission through chain 23,31 moves to setting specified altitude assignment H with clamping and releasing means 1 along curvilinear guide 13; Drive 12 withdrawals of cylinder 11 pulling clamping rods and realize release, accomplish once test tested perambulator.After initial collision was accomplished, under anti-secondary impact device effect, tested perambulator was back to zero point.The control servomotor, the transmission through chain 23,31 moves to zero-bit with clamping and releasing means 1.Accomplish the preparation of repeated test next time, after the off-test, data acquisition and processing (DAP) system acquisition record data, Treatment Analysis is accomplished storage.
Above-mentioned instance implements not limit in any form the present invention, and all technical schemes that mode obtains of taking to be equal to replacement or equivalent transformation are all in protection domain of the present invention.
