Definitions

  • Subject of the invention is a cam mechanism for cocking the firing pin striking the primer of the gunpowder bullet, which may be used especially in devices driven by gunpowder gas energy.
  • Each device in which there is a firing pin primer striking mechanism needs a mechanism for cocking and releasing the pin.
  • Traditional solutions based on reloading by means of lock movement - automatically or manually - as well as releasing with the trigger are not sufficiently susceptible to adaptation for remote control.
  • the possibility of remote control of the pin is especially essential in the case of mobile robots for special uses and their accessories (tools) powered with the energy of gunpowder gas.
  • the aim of the invention is a simple pin cocking mechanism susceptible to remote control.
  • Mechanism according to the invention is equipped with a spring situated on the external surface of the firing pin, a revolving cam with a drive gear as well as a backstop mechanism the release of which initiates movement of the cocked firing pin. It is characterized in that it is equipped with a shaft crossing through the firing pin and leading through notches in the housing. One end of this shaft is located in a notch in the cam leading along a helix. The ends of this helical notch are connected with a linear notch parallel to the axis of revolution of the cam. The movement of the shaft, forced by the rotation of the cam, at the same time causes the retraction of the firing pin and straining of the spring until the pin is blocked in cocked position.
  • the aforementioned backstop mechanism is part of the releasing and securing mechanism of the firing pin constituted by two levers coupled with each other by means of a toothed gear.
  • the releasing and securing mechanism of the firing pin is equipped with an electromagnetic actuator.
  • Fig.1 shows a longitudinal section of the cam mechanism
  • Fig.2 shows partial section of the backstop mechanism
  • Fig.3 and Fig.4 show two different perspective views of the cam of the mechanism itself.
  • a cam 2 with drive gear 3, advantageously cogged, is placed in housing 1 .
  • the cam 2 is supported in bearing 4 secured by a plate 5 and by a bearing-protection plate 6.
  • a shaft 7 is lead through housing 1 notches and passes through a hole in firing pin 8.
  • One end of the shaft is located in the notch 9 of the cam 2.
  • the notch 9 is led along a helix and the ends of this helical notch 9 are connected with a linear notch 10 parallel to the axis of revolution of the cam 2.
  • the cam 2 moves shaft 7 in the housing 1 notches.
  • the shaft 7 is secured against falling out on the one side by the cam 2 and on the other side by a plate 1 1 screwed to the housing 1 with screws 12.
  • a securing lever 23 coupled with the backstop lever 19 by means of a toothed gear serves to secure the firing pin 8 against unwanted movement in the direction of the bullet's primer and an unintended shot.
  • the securing lever 23 limits the firing pin 8 movement by means of blocking the movement of shaft 7 in housing 1 in the direction of the bullet's primer.

Abstract

L'invention concerne un mécanisme de came pour armer le percuteur d'une arme, le mécanisme étant pourvu d'un ressort (13) situé sur la surface externe du percuteur (8), une came rotative (2) ayant un engrenage d'entraînement (3) et un mécanisme de butée (19), dont la libération déclenche un mouvement du percuteur armé (8), étant en outre pourvue d'un arbre (7) passant à travers le percuteur (8) et menant à travers des encoches dans le boîtier (1) de l'arme. Une extrémité de cet arbre (7) est située dans une encoche (9) de la came (2) menant le long d'une hélice, des extrémités de cette encoche (9) étant reliées au moyen d'une encoche linéaire (10), parallèle à l'axe de rotation de la came (2). Le mouvement de l'arbre (7), forcé par la rotation de la came (2), provoque en même temps la rétractation du percuteur (8) et la tension du ressort (13) jusqu'à ce que le percuteur (8) soit bloqué en position armée. Le mécanisme de butée (19) du percuteur fait partie d'un mécanisme de libération et de fixation constitué par deux leviers (19, 23) couplés au moyen d'une roue dentée.
