A power device for impact testing of auto parts

Abstract

The invention provides a power device for the impact test of auto parts, belonging to the technical field of auto test equipment. It solves the problems of large space occupation and high manufacturing cost of existing auto parts impact test equipment. The power device for the impact test of auto parts includes a vertical support and a cylinder. The vertical support is formed by connecting a number of gas storage pipes, and several gas storage pipes are connected to form an air storage cavity. The vertical support slides along the vertical direction. There is a gas collecting box, the gas collecting box is connected with the gas storage chamber, the cylinder is fixedly connected to the gas collecting box, and the piston rod of the cylinder is set horizontally, the cylinder body of the cylinder is connected with the gas collecting box, and the cylinder body of the cylinder is connected with the gas collecting box. A solenoid valve is arranged between the boxes, and a driving mechanism capable of driving the gas collecting box to move up and down is arranged on the vertical support. The gas pressure required by the power device for the impact test of the auto parts is small, and the overall occupied space is small, and the production cost is low.

[0002] The impact test of auto parts refers to using the parts as the target, and then launching the projectile through the power device and impacting the target, so as to obtain test data, such as the calibration test of the pedestrian protection flexible leg, the launch test of the half-length dummy, and the calibration of the locomotive ACU's basketball misuse test, the current impact test device for auto parts usually consists of a high-strength bracket, a small cylinder fixed on the bracket, and a set of pressurization equipment. During the test preparation process, high-pressure gas is passed through a The 6-point pipe is filled into a cylinder with a diameter of about 80mm, and the piston rod in the cylinder is pushed out to launch the projectile, that is, the projectile needs to be accelerated to a speed of about 7m / s under a stroke of about 500mm, but the supply for the cylinder The gas pipeline is long and thin. In order to ensure that the gas can quickly enter the cylinder and push the piston, the test gas needs to be high-pressure gas, so high-pressure booster equipment is required for boosting. The equipment takes up a lot of space and the manufacturing cost High, in addition, the entire equipment and control system are relatively complex, difficult to maintain and repair
