Pendulum hanging and swinging mechanism for oscillography impact testing machine

Abstract

The invention discloses a pendulum hanging and swinging mechanism for an oscillography impact testing machine, which comprises a main machine, a pendulum, an off-hooking device, a buffer unit and a lifting-swinging angle adjusting device, wherein the pendulum is connected with the main machine through a pendulum rotating shaft; the off-hooking device comprises electromagnetic absorbing iron and a supporting seat for supporting the electromagnetic absorbing iron, the outer side of the supporting seat is provided with a pull rod which is connected with one end of a spring, the other end of the spring is connected with a hook shaft which is provided with a hook, and the hook is connected with a hammer hook; the buffer unit comprises a buffer spring which is connected with a buffer head, and the outer side of the buffer head is provided with a limit switch; and the lifting-swinging angle adjusting device comprises an adjusting disc provided with an arc chute. The pendulum hanging and swinging mechanism applied to the same pendulum of the same oscillography impact testing machine can accurately and quantitatively change the impact velocity and the impact energy, and widen a larger space for impact performance tests of materials.

Description

Technical field: [0001] The invention relates to the field of oscillometric impact testing machines, and in particular to a pendulum hanging mechanism of the oscillometric impact testing machine. Background technique: [0002] Now the pendulum of the general oscillometric impact testing machine on the market can not change the swing angle, so the impact speed is constant, so in the case of the same pendulum, the impact energy is constant. Since the swing angle of the pendulum cannot be changed, we cannot use it to accurately and quantitatively change the impact velocity and impact energy, which limits the wider application range of the oscillometric impact tester. Invention content: [0003] The object of the present invention is to provide a pendulum hanging mechanism of an oscillometric impact testing machine to solve the problem that the pendulum lifting angle of the existing oscillometric impact testing machine is fixed, the impact speed cannot be changed, the impact e...
