Abstract

The invention discloses an impact testing machine and is used for reducing the size of the impact testing machine, improving the reaction speed of drop hammer control and improving the testing accuracy of the impact testing machine. The impact testing machine comprises a base, a support, a lead screw lifting mechanism, a first clamp claw, a first clamp claw driving mechanism, a drop hammer mechanism, a part mounting platform and a control system. The lead screw lifting mechanism comprises a servo motor, a lead screw and a first clamp claw fixing seat; the lead screw is in driving connection with the servo motor, and the first clamp fixing seat is in driving connection with the lead screw; the first clamp claw is mounted on the first clamp claw fixing seat; the first clamp claw driving mechanism is in driving connection with the first clamp claw and is provided with a start button; the part mounting table is arranged on the base and comprises a part fixing structure; the control systemincludes an operating interface and a controller connected to the operating interface, the controller is connected to the servo motor, and the controller is used for controlling the servo motor to drive the lead screw to drive the first clamp claw fixing seat to a set position according to a first instruction of the operating interface.

Description

technical field [0001] The invention relates to the technical field of testing equipment, in particular to an impact testing machine. Background technique [0002] Impact test is generally a test method to determine the safety, reliability and effectiveness of military and civilian equipment when they are subjected to external shocks. In the impact test, the main equipment is the impact testing machine. According to the different working structure, the impact testing machine is divided into pendulum impact testing machine and drop hammer impact testing machine; according to the different operation methods, it is divided into manual impact testing machine, semi-automatic Impact testing machine, automatic impact testing machine. [0003] The impact testing machine in the prior art adopts a pneumatic driving method to control the drop weight, and the test site needs to have an air source, and the response is slow, and the volume of the impact testing machine is relatively larg...
