Abstract
The invention discloses a split piston braking device. The split piston braking device comprises a piston body (1), a braking ring (4) and a guiding body (2), wherein the front of the piston body (1) is connected with the bottom of an elastic body in a threaded manner; a circular groove is formed in the inner side of the middle of the piston body (1); a step hole is formed in the outer side of the middle of the piston body (1) and penetrates in the circular groove; a semi-circular step surface is arranged at one end of the guiding body (2) and is provided with a threaded hole; the semi-circular step surface of the guiding body (2) is matched with the circular groove of the piston body (1) and is connected with the piston body (1) through screws (3); a split piston is arranged in the middle of a launching barrel (5); the front of the split piston is connected with the bottom of the elastic body in a threaded manner; a weakening groove is formed between a circular plane and the piston body (1); and the braking ring (4) is annular and is arranged on a barrel opening of the launching barrel (5). Threads between an elastic support and the body are omitted, the elastic support is prevented from flying out of the barrel, and braking safety is improved.
Description
Technical field
The present invention relates to a kind of braking device, particularly a kind of Split piston braking device.
Background technique
Current piston braking device is generally made up of piston only, bullet holder and brake hoop.Piston only cylindrical is cylindrical, and there is tapped hole at center.There is outside thread bullet holder one end, is connected with piston only, and the other end is circular flat, is connected with bullet.Brake hoop is arranged in launching tube nozzle.During transmitting, in launching tube, produce high-pressure gas, promote piston only, bullet holder and bullet and travel forward, after nozzle, piston only and brake hoop collide, and brake hoop distortion absorbs collision energy, piston only and bullet holder are braked, and the connection with bullet holder broken by body under effect of inertia, flies out outside cylinder.The shortcoming of this mode is, bullet holder and piston only are threaded connection, and during braking, bullet holder can pull screw thread and fly out outside cylinder under effect of inertia.
Summary of the invention
The object of the present invention is to provide a kind of Split piston braking device, when solving braking, bullet holder can pull screw thread and the problem that flies out outside cylinder under effect of inertia.
A kind of Split piston braking device, comprising: piston only and brake hoop, also comprise: guide way.The both sides of piston only are the different cylindrical body in cross section, chamfering is had between the large cylindrical body of the cylindrical body that cross section is little and cross section, the stepped cylindrical body of cylindrical body that cross section is little, there is screw thread on surface, stepped cylindrical high ladder place, be threaded connection bottom piston only and body, there is weakening groove on surface, stepped cylindrical low ladder place; There is circular trough one side end face of the little cylinder connection of the cylindrical body that cross section is large and cross section, and the cylindrical opposite side end face that cross section is large has shoulder hole, and this shoulder hole is through to circular trough.Guide way is semicircle, and there is the cambered surface of braking one end, and the other end has semicircle step surface, and step surface has tapped hole.Each piston only installs two guide waies, and the semicircle step surface of two guide waies coordinates with the circular trough on piston only, and is connected with piston only by screw.Brake hoop is ring, is placed in launching tube nozzle.
A during work of Split piston braking device, piston only and guide way connect into piston, put into launching tube after being connected with body, then brake hoop are placed on launching tube nozzle and fix.During transmitting, piston travels forward under combustion gas effect, promotes bullet simultaneously and travels forward.When moving to launching tube nozzle, piston and brake hoop collide, and brake hoop is along the arc deformation of guide way, and piston is braked, and the weakening groove between piston only broken by body under effect of inertia, flies out outside cylinder.
Split piston braking device is by the screw thread between removal bullet holder and body, the method adopting barrel confined piston radial deformation, and the problem that when having stopped to launch, bullet holder flies out outside cylinder, improves Security during braking.

Embodiment
A kind of Split piston braking device, comprising: piston only 1 and brake hoop 4, also comprise: guide way 2.The both sides of piston only 1 are the different cylindrical body in cross section, chamfering is had between the large cylindrical body of the cylindrical body that cross section is little and cross section, the stepped cylindrical body of cylindrical body that cross section is little, there is screw thread on surface, stepped cylindrical high ladder place, be threaded connection bottom piston only 1 and body, there is weakening groove on surface, stepped cylindrical low ladder place; There is circular trough one side end face of the little cylinder connection of the cylindrical body that cross section is large and cross section, and the cylindrical opposite side end face that cross section is large has shoulder hole, and this shoulder hole is through to circular trough.Guide way 2 is semicircle, and there is the cambered surface of braking one end, and the other end has semicircle step surface, and step surface has tapped hole.The semicircle step surface each piston only 1 being installed two guide waies, 2, two guide waies 2 coordinates with the circular trough on piston only 1, and is connected with piston only 1 by screw 3.Brake hoop 4 is ring, is placed in launching tube 5 nozzle.
A during work of Split piston braking device, piston only 1 and guide way 2 connect into piston, put into launching tube 5 with body after being connected, and then brake hoop 4 are placed on launching tube 5 nozzle and fix.During transmitting, piston travels forward under combustion gas effect, promotes bullet simultaneously and travels forward.When moving to launching tube 5 nozzle, piston and brake hoop 4 collide, and brake hoop 4 is along the arc deformation of guide way 2, and piston is braked, and the weakening groove between piston only 1 broken by body under effect of inertia, flies out outside cylinder.
