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
The present invention relates to ballistic testing machine technical field, specifically a kind of pendulum impact machine is hung pendulum snubber assembly.
Background technology
General pendulum impact machine in pendulum hanging and swinging process for preventing that pendulum from impacting and shaking and structurally all designed mechanical buffer device--spring buffer, but effect is not very desirable, still produce and impact and shake, like this equipment and testing crew are all likely damaged, we have manufactured a kind of bydraulic buffers by designing and improving for this reason, good by result of use, fundamentally solved impact and jitter problem.
Summary of the invention
The object of the present invention is to provide a kind of pendulum impact machine to hang pendulum snubber assembly, by buffer unit is effectively verified and tested, designed a kind of more effectively snubber assembly.
The present invention solves the technical scheme that its technical matters takes: a kind of pendulum impact machine is hung pendulum snubber assembly, comprise frame and pendulum, between pendulum and frame, be provided with a set of snubber assembly, it is characterized in that, described snubber assembly comprises rocking arm, electromagnetic controller and hook tongue, rocking arm is polygonal body, rocking arm middle part and two ends have respectively mounting hole, rocking arm middle part is articulated in frame, the hinged electromagnetic controller in rocking arm one end, the hinged hook tongue of the other end, in the upper end of hook tongue, it is hook working point, lower end is shock absorbing point, hook on hook tongue upper end and pendulum matches, hook working point adopts removable shock-resistant high-abrasive material piece, the shock absorbing point of lower end and a bydraulic buffers contact.
Described bydraulic buffers is piston-type hydraulic buffer, and in two cavitys of bydraulic buffers, has one-way throttle hole and the bidirectional throttle hole of perforation, and its time of upspringing is fast half of buffer compression time, can realize slow compression, upsprings fast.
The invention has the beneficial effects as follows:
Buffer gear in the present invention is bydraulic buffers, structurally should notice that the tolerance clearance of piston and inner surface of cylinder block should be controlled suitably, not so the motion of piston clamping stagnation can occur dumb.On piston, whether the size of throttle orifice selects the effect of suitable directly impact buffering in addition, thus the selection of throttle orifice diameter be extremely important be key position.The shake when buffer action by bydraulic buffers has fundamentally solved pendulum hanging and swinging and touch building, realize hang balance steady without impacting.
This bydraulic buffers utilizes hydraulic principle, make it produce hydraulic spring grease cup effect, at airtight liquid in container, be incompressible, act on fluid the flowing by the bidirectional throttle hole on piston at piston two ends, piston is moved left and right slowly and drive fork not produce violent shake after hanging hammer, by bidirectional throttle hole and one-way throttle hole, work simultaneously simultaneously, realize and upspringing fast.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is Fig. 1 partial enlarged drawing;
Fig. 3 is A place partial enlarged drawing in Fig. 2;
In figure: 1 frame, 2 pendulums, 3 rocking arms, 31 mounting holes, 4 hook tongues, 41 hook working points, 42 shock absorbing points, 5 electromagnetic controllers, 6 hooks, 7 bydraulic bufferss, 71 one-way throttle holes,
72 bidirectional throttle holes.
Embodiment
As shown in FIG. 1 to 3,
Hang a pendulum snubber assembly, comprise frame 1 and pendulum 2, between pendulum 2 and frame, be provided with a set of snubber assembly, for preventing, impact.Snubber assembly comprises rocking arm 3, hook tongue 4, electromagnetic controller 5, and rocking arm 3 is a polygonal body, and its middle part and two ends have respectively mounting hole 31, for installing.Rocking arm middle part is hinged in frame; the hinged electromagnetic controller 5 in rocking arm 3 one end; the hinged hook tongue 4 of the other end; the upper end at hook tongue 4 is shock absorbing point 42 for linking up with 41， lower end, working point, and the hook 6 on hook tongue upper end and pendulum matches; hook working point adopts removable shock-resistant high-abrasive material piece; inlay installation, the shock absorbing point of lower end and a bydraulic buffers 7 contact, and bydraulic buffers is fixed on rocking arm 3.This bydraulic buffers is piston-type hydraulic buffer, and one-way throttle hole 71 and the bidirectional throttle hole 72 in two cavitys of bydraulic buffers with perforation, whether the size of two throttle orifices selects the effect of suitable directly impact buffering, thus the selection of throttle orifice diameter be extremely important be key position.The shake when buffer action by bydraulic buffers has fundamentally solved pendulum hanging and swinging and touch building realize hang balance steady without impacting.Work as compression, process is slower, when upspringing, rapider, and its time of upspringing is fast half of buffer compression time, can realize slow compression, upsprings fast.
Except the technical characterictic described in instructions, be the known technology of those skilled in the art.
