Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figures 1 to 4, a kind of damping high order smooth pattern of the present utility model takes out housing apparatus automatically, comprise cartridge extractor 2 and cam 8, described cartridge extractor 2 and cam 8 are arranged on barrel 11 respectively by cartridge extractor axle 9 and camshaft 4, cartridge extractor 2 shape is that two ends are narrow, middle wide, profile is the platy structure of curved surface, cartridge extractor 2 is outer gibbosity towards the outline line of the one side of cam 8, cartridge extractor axle 9 is 3:1 apart from the ratio of distances constant of cartridge extractor 2 front end and bottom, cartridge extractor axle 9 is provided with reduction torsion spring 3, described cartridge extractor 2 front end is provided with shell case hook and coordinates with the cartridge case root edge of shell case 1, cartridge extractor 2 rear end to be close on cam 8 on contour surface, the hinged first connecting rod 5-1 upper end, lower end of cam 8, the lower end of first connecting rod 5-1 simultaneously with the upper end thereof of second connecting rod 5-2 and third connecting rod 5-3, lower end and the slide block 7 of second connecting rod 5-2 are hinged, slide block 7 is provided with screwed hole, in screwed hole, stud is installed, stage clip 6 is enclosed within stud, stage clip 6 other end is connected with barrel 11, stage clip 6 comprises interior stage clip and external pressure spring, external pressure spring internal diameter is greater than interior stage clip external diameter, slide block 7 is positioned at the chute of coulisse 12, coulisse 12 is positioned at slide block 7 other end direction is provided with and takes out shell template 13, chute is dovetail groove, the dovetails coordinated with dovetail groove is extended with bottom slide block 7, lower end and the barrel 11 of described third connecting rod 5-3 are hinged, when being in loose shelly state, the angle of first connecting rod 5-1 and second connecting rod 5-2 is obtuse angle.
As shown in Figures 5 to 7, after Canon launching, barrel 11 recoil drives whole shell systems of taking out to move backward, slides in the coulisse 12 of slide block 7 on gun carriage.After recoil is terminated, barrel 11 starts to enter again, and whole shell systems of taking out advances.As shown in Figure 5, at this moment, shell template 13 stop motion is taken out in slide block 7 contact, starts to take out shell.As shown in Figure 6, barrel 11 continues to enter again, and slide block 7 maintains static, and barrel 11 continues to advance left with third connecting rod 5-3, and drive second connecting rod 5-2 to rotate counterclockwise, thus impel cam 8 also to rotate counterclockwise, cam 8 curved surface acts on cartridge extractor 2 galianconism lower end.During owing to starting, cam 8 contour curve is comparatively mild, and the angle that cartridge extractor 2 turns over is very little, then to act on the shell speed of taking out of cartridge case very little for cartridge extractor 2, and when between second connecting rod 5-2 and third connecting rod 5-3, angle reduces 5 °, cartridge extractor 2 completes loose shell process.As shown in Figure 7, cam 8 is in the rise stage afterwards, takes out shell speed and rises rapidly, and when between two connecting rods, angle reduces 15 °, cartridge extractor 2 completes takes out shell process.The stage clip 6 be fixed between slide block 7 and barrel 11 in the loose shell stage starts compressed energy-storage, and external pressure spring 6 compressed energy-absorbing before this, and in the increase moved along with multiple carry, stage clip 6 contacts with slide block 7, and now spring rate increases, interior external pressure spring 6 together compressed energy-storage.Take out after shell terminates, barrel 11 enters position again, and stage clip 6 discharges potential energy to be made second connecting rod 5-2 promote slide block 7 to reset, and cam 8 turns round simultaneously, and cartridge extractor 2 resets under the effect of reduction torsion spring 3, and whole shell systems of taking out gets back to initial position.
The shell speed of taking out of beginning can be made very little by this connection rod set and the Combination Design of cam 8, along with the increase gradually of Extraction force, cartridge extractor 2 can complete loose shell process stably.Afterwards in the rise stage of cam 8, take out shell speed and rise rapidly, cartridge extractor 2 has accelerated to take out shell process.In addition, by the different characteristics of motion can be obtained the different designs of connection rod set relative length, cam 8 contour curve and cartridge extractor 2 and take out shell performance.
The above is only preferred embodiment of the present utility model; be noted that for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
