Demarcate locomotive ACU basketball misuse experiment, current auto parts and components impact test apparatus generally by the very high support of intensity and
A fixed small cylinder on support, and a set of supercharging equipment composition, test and pass through gases at high pressure in set-up procedure
It is in charge of the cylinder for being filled with a diameter of 80mm or so for one 6, the piston rod in cylinder is released, emitting substance is launched, that is, needed
Emitting substance to accelerate to 7m/s or so speed under 500mm or so stroke, but for cylinder body supply length of pipe compared with
Greatly, pipeline is thinner, and in order to ensure that gas can rapidly enter cylinder body and promote piston, test gas is needed for gases at high pressure, because
This needs high pressure supercharging equipment to be pressurized, and equipment occupation space is larger, and manufacturing cost is high, in addition, whole equipment and control are
System is all more complicated, and maintenance, repair are difficult.
The content of the invention
The purpose of the present invention is above mentioned problem be present for existing technology, it is proposed that a kind of auto parts and components impact test
Power set, the gas pressure needed for the power set of the auto parts and components impact test is small, and it is overall occupy little space, it is raw
It is low to produce cost.
The purpose of the present invention can be realized by following technical proposal：A kind of power dress of auto parts and components impact test
Put, including stand type support and cylinder, it is characterised in that the stand type support is fixedly connected with to be formed by some cylinders, and some
Cylinder is connected to form air storing cavity, vertically slidably connects collector box in the stand type support, the collector box with
Air storing cavity is connected, and the cylinder is connected on collector box, and the piston rod of cylinder is horizontally disposed with, the cylinder body and collection of the cylinder
Gas box is connected, and the volume of the air storing cavity is more than the volume of collector box, and the volume of the collector box is more than the appearance of cylinder block
Product, the magnetic valve that can control break-make between the cylinder body of cylinder and collector box is provided between the cylinder body and collector box of the cylinder,
The stand type support, which is provided with, can drive the drive mechanism that collector box moves up and down.
