Problems solved by technology

[0002] Generally, the pendulum impact machine is designed with a mechanical buffer device-spring buffer in order to prevent the impact and vibration of the pendulum during the pendulum hanging process, but the effect is not very satisfactory, and impact and vibration are still generated, which is harmful to the equipment Both the tester and the tester may cause injury. For this reason, we have designed and improved a hydraulic shock absorber, which has a good effect and fundamentally solves the problem of shock and vibration.

Embodiment Construction

[0014] like Figure 1 ~ Figure 3 as shown,

[0015] A pendulum buffer device for a pendulum impact machine, comprising a frame 1 and a pendulum 2, and a set of buffer devices is arranged between the pendulum 2 and the frame to prevent impact. Buffer device comprises rocking arm 3, hook tongue 4, electromagnetic controller 5, and rocking arm 3 is a polygonal body, and its middle part and both ends have installation hole 31 respectively, is used for installing. The middle part of the rocker arm is hinged on the frame. One end of the rocker arm 3 is hinged to an electromagnetic controller 5, and the other end is hinged to a hook tongue 4. The upper end of the hook tongue 4 is the hook working point 41, and the lower end is a buffer impact point 42. The upper end of the hook tongue Cooperate with the hook 6 on the pendulum. The working point of the hook is made of a replaceable impact-resistant and wear-resistant material block, which is inlaid and installed. The buffer impact po...

Abstract

The invention discloses a hanging pendulum buffer device of a pendulum impact testing machine. The hanging pendulum buffer device comprises a rack and a pendulum, wherein a buffer device is arranged between the pendulum and the rack. The hanging pendulum buffer device is characterized in that the buffer device comprises a rocking arm, an electromagnetic controller and a hook tongue, wherein mounting holes are respectively formed in the middle and the two ends of the rocking arm; the middle of the rocking arm is hinged on the rack; one end of the rocking arm is hinged with an electromagnetic controller, and the other end of the rocking arm is hinged with a hook tongue; the upper end of the hook tongue is a hook working point, and the lower end of the hook tongue is a impact buffer point; the upper end of the hook tongue is matched with a hook on the pendulum; and the impact buffer point at the lower end of the hook tongue abuts against a hydraulic buffer. The the hydraulic buffer serves as a buffer element in the hanging pendulum buffer device, and according to the structure of the hydraulic buffer, the fit clearance between a piston and the inner surface of a cylinder body is properly controlled, so that the phenomenon that the movement of the piston is out of nimbleness and not flexible can be avoided. Through a buffer action of the hydraulic buffer, the problems that the joggling and the collision of the hanging pendulum can be radically solved, and thus the stability and no-impact of the hanging pendulum are realized.

Description

technical field [0001] The invention relates to the technical field of impact testing machines, in particular to a pendulum buffer device for a pendulum impact machine. Background technique [0002] Generally, the pendulum impact machine is designed with a mechanical buffer device-spring buffer in order to prevent the impact and vibration of the pendulum during the pendulum hanging process, but the effect is not very satisfactory, and impact and vibration are still generated, which is harmful to the equipment Both the tester and the tester may cause injury. Therefore, we have designed and improved a hydraulic shock absorber, which has a good effect and fundamentally solves the problem of shock and vibration. Contents of the invention [0003] The object of the present invention is to provide a pendulum buffer device for a pendulum impact machine. Through effective verification and experiments on the buffer components, a more effective buffer device is designed. [0004] T...
