An impact test device

Abstract

The invention discloses an impact test device, and relates to the field of impact tests. The device comprises a base, a workpiece clamp, a punch clamp, a machine seat, a crankshaft motion mechanism and a displacement control module. The base is provided with a pressure testing module; the pressure testing module is used for testing a pressure on the workpiece; at least two stand columns are further arranged on the base; the workpiece clamp is arranged above the pressure testing module and used for fixing the workpiece; the punch clamp is arranged above the workpiece and used for fixing a punch; the machine seat is in sliding connection with the stand columns; the crankshaft motion mechanism is arranged on the machine seat, is in transmission connection with the punch clamp, and is used fordriving the punch clamp to move in a direction close to or far away from the workpiece so as to realize an impact motion; and the displacement control module is in transmission connection with the machine seat, and is used for driving the machine seat to move so as to realize adjustment and testing of a displacement distance between the punch and the workpiece. The device is adjustable in impactforce, accurate in impact position, simple to operate and low in cost, and the maximum impact force can reach ten thousand Newton.

Description

technical field [0001] The invention relates to the field of impact testing, in particular to an impact testing device. Background technique [0002] The impact test device is a device that uses a high-speed moving impact block to perform an impact test on the specimen, and is used to simulate the effect of high-speed impact. For the working conditions such as impact and extrusion on the surface, especially the coating surface, the coating will often lead to peeling and failure when subjected to impact and extrusion loads. The impact test can be carried out with the impact test device, and the performance and life of the coating can be evaluated by simulating the working conditions. [0003] Most of the traditional impact tests use drop hammer impact equipment, and the drop hammer can be free fall or accelerated fall. The free fall impact is not strong enough, and the accuracy of the impact position cannot be guaranteed. Although the impact force of the accelerated fall i...

The free fall impact is not strong enough, and the accuracy of the impact position cannot be guaranteed

Although the impact force of the accelerated fall increases, there is still the problem of low accuracy of the impact position.

At present, some other impact test devices can only perform impact tests under a fixed impact force, and cannot perform impact tests under different impact loads. For different working loads, the impact test devices cannot achieve versatility
