The invention has the advantages of convenient and quick testing, accurate speed control and short accelerating travel, can test the parts instead of real automobile so as to greatly lower the testing cost.
Description
Technical field
The present invention relates to a kind of car model collision test device, relate in particular to a kind of simulated collision test machine of testing automobile parts.
Background technology
In the impact test of automobile and works, need automobile be accelerated to the setting speed of a motor vehicle, and make it to collide with works.Because vehicle impact testing has to a certain degree danger and Unpredictability, therefore generally drive a car, but make the mode of instruction carriage acceleration through external force without the driver.At present, the method that instruction carriage is quickened mainly contains electric propulsion mode, hydraulic driving mode, tractor mode of traction or the like.Wherein the electric propulsion mode is to adopt more a kind ofly, and its major advantage is that control accuracy is higher.
But with regard to prior art, even if also need be through the car load test to the test of the crash tests of indivedual auto parts and components, inefficiency so not only, and cost of idleness greatly be unfavorable for that test of many times is to obtain accurate result.The production firm of some auto parts and components does not particularly need and does not possess the real vehicle test condition, carries out product test and has very big difficulty.Even domestic automobile parts crash tests is a blank at present.
Summary of the invention
The technical matters that the present invention will solve provides that a kind of convenient test is quick, and speed control is accurate, and the impact testing machine of pneumatic piston type automobile parts that accelerating travel is short can replace true car test parts, has greatly reduced testing cost.
In order to solve the problems of the technologies described above, the present invention is achieved through following technical scheme:
A kind of impact testing machine of pneumatic piston type automobile parts; Comprise that an end is provided with the collision barrier and is used for the running rail that model car slides; Said model car is realized motion through the traction guiding mechanism; Said traction guiding mechanism comprises the cylinder through air supply opening driven plunger motion, and said piston is connected with the dragline on two pulleys;
Said model car is provided with and is used for the automatic clamping, the release unit that are connected with said dragline, and said automatic clamping, release unit comprise cam mechanism, and the spikes/low-points of said cam mechanism is connected with clamping device.
Said model car front end is provided with snubber assembly.
The invention has the beneficial effects as follows:
(1) the present invention can make model car under the driving of traction guiding mechanism, on running rail, be free to slide, and with certain speed bump collision barrier, to realize for the detection that is installed in the various products on the model car; For example, can test the impact resistance intensity of seat to being furnished with dummy's automotive seat impact.
(2) automatic clamping, the release unit installed on the model car have two kinds of functions: the firstth, clamp function, and model car is fixed on the dragline, dragline can drive model car and was synchronized with the movement this moment, thus the accelerator of implementation model car; The secondth, break away from function, model car and dragline are broken away from fully, guarantee model car when arriving the regulation speed per hour, do not receive to carry out impact test, the real simulation collision process with the experiment barrier under any external force effect.
(3) also be provided with snubber assembly on the model car, have two big functions equally: the firstth, crashproof function has avoided model car in knockout process, to be damaged; The secondth, the impact control function; Through the cushion stroke of control and change snubber assembly, come the collision buffering stroke of implementation model car, thereby controlling models car impact size (is the retarded velocity size of controlling models car; Like 40G etc., 1G=1 the about 9.8m/s of acceleration of gravity
2).
(4), have convenient and swift and many characteristics such as speed control is accurate, accelerating travel weak point through the collision performance of this collision tester testing automobile parts.
(5) the present invention can replace its parts of real vehicle test, greatly reduces the cost of each test; Particularly, especially wherein do not need and do not possess the unit of true car test condition, brought Gospel,, filled up this type of project testing blank at home therefore for the test of domestic automobile parts contributes for the production firm of some auto parts and components.

Embodiment
Below in conjunction with accompanying drawing the present invention is made further detailed description:
As shown in Figure 1, the invention discloses a kind of auto parts and components collision tester, comprise the model car 1 that is used for impact test, be equipped with on this model car 1 and step up relevant infrastructure device such as release unit 9, model people and snubber assembly 10 automatically.On the said model car 1 various auto parts and components products can be installed, carry out impact test, with the impact resistance intensity of testing automobile parts product.
Said model car 1 is free to slide in the travel range of running rail 4, and the end of said running rail 4 is provided with a collision barrier 3.Said model car 1 will clash into said collision barrier 3 with certain speed.
The traction guiding mechanism that moves through of said model car 1 realizes that said traction guiding mechanism comprises a cylinder 8 as drive unit, and said cylinder 8 comprises air supply opening 6 and piston 7.Said cylinder 8 utilizes from air supply opening 6 and feeds gases at high pressure and driven plunger 7 motions.The traction guiding mechanism also comprises two pulleys 5, according to actual conditions, can also comprise some auxiliary wheels; Be wound with dragline 2 on two pulleys 5, dragline 2 is connected with said piston 7.Like this, utilize compressed air-driven piston 7 can drive dragline 2 around two pulley 5 cycle rotations.
Said model car 1 is clamped on the said dragline 2 through stepping up release unit 9 automatically; And make the disengaging fully of model car 1 and dragline 2 in a certain position moment realization of said running rail 4; Guarantee model car 1 when arriving the regulation speed per hour, do not receive to carry out impact test with collision barrier 3 under any external force effect.The said release unit 9 that steps up automatically comprises the cam mechanism that can manually control, and the spikes/low-points of said cam mechanism is connected with clamping device.Bump against the block of setting on the said running rail 4 when cam mechanism after, cam mechanism rotates and clamp system and said dragline 2 is broken away from, and moves with implementation model car 1 and with the disengaging of dragline 2.
Said model car 1 also is provided with snubber assembly 10, and said snubber assembly 10 is utilized the buffering of the resistance implementation model car 1 of a circulating oil path by two adjustable oil cylinders of stroke.Snubber assembly 10 avoids model car 1 in knockout process, to be damaged on the one hand; The more important thing is that snubber assembly 10 utilizes the cushion stroke of oil cylinder in control and the change system, come the collision buffering stroke of implementation model car 1, thereby controlling models car 1 impact is big or small.That is to say the retarded velocity of controlling models car 1 size, 40G etc. for example, 1G=1 the about 9.8m/s of acceleration of gravity
