Abstract
The utility model discloses a kind of combined type casing, comprise casing body parts one, below described casing body parts one, be connected with casing body parts two; The medial surface of the bottom of described casing body parts one offers the first gathering sill, and the tail end on the top of casing body parts one offers the second gathering sill; The front end of described casing body parts two is provided with two tenons coordinated with the first gathering sill on casing body parts one, and the rear end of casing body parts two is provided with the guide pad coordinated with the second gathering sill on casing body parts one; Described casing body parts one and casing body parts two are connected and fixed by connecting pin bottom casing and casing afterbody connecting pin.The split-type design of this combined type casing solves a difficult problem for integral type casing processing technology difference, is conducive to batch machining simultaneously.
Description
Technical field
The utility model belongs to firearms field, is specifically related to the combined type casing that the two-tube firearms of a kind of flat use.
Background technology
The two-tube firearms casing of general flat adopts integral type, as shown in Figure 1, directly process the process of finished product from blank and have following difficult point: first, as shown in Figure 2, hit pinhole 10 is inclined holes of a space angle, process this hole and must enter bore milling cutter 13 from casing afterbody, hit pinhole face is larger to casing tail end distance, length is approximately 80mm, and hit pinhole diameter is φ 6, and cutter 13 not only requires long enough, and requirement of strength is also high especially, so processing casing hit pinhole 10 easily causes cutter 13 to fracture, and size is not controlled yet, and qualification rate is low.Secondly, as shown in Figure 3, the processing of Breech block groove 11 is similar with hit pinhole processing, but Breech block groove 11 is strip grooves, and because casing tail end has supporting seat 12 to block, processing the necessary oblique insertion cutter 13 of this Breech block groove, is also the cutter that easily fractures.So integral type casing crudy is often also difficult to control, more impossiblely realize the large batch of production of casing.
Utility model content
In order to the processing work manufacturability solving existing flat two-tube firearms casing integral type casing is poor, casing crudy is made to be difficult to control, and a difficult problem for production in enormous quantities can not be adapted to, the utility model provides a kind of combined type casing, this casing is connected to form by casing body parts one and casing body parts two, casing body parts one and casing body parts two individually process position on it, again the casing body parts one machined and casing body parts two are combined and fix with alignment pin, casing is designed to the split type problem solving integral type casing processing technology difference, improve crudy simultaneously, also batch production is conducive to.
The utility model is achieved through the following technical solutions:
Combined type casing, comprises casing body parts one, is connected with casing body parts two below described casing body parts one; The medial surface of the bottom of described casing body parts one offers the first gathering sill, and the tail end on the top of casing body parts one offers the second gathering sill; The front end of described casing body parts two is provided with two tenons coordinated with the first gathering sill on casing body parts one, and the rear end of casing body parts two is provided with the guide pad coordinated with the second gathering sill on casing body parts one; Described casing body parts one and casing body parts two are connected and fixed by connecting pin bottom casing and casing afterbody connecting pin.
Further, described casing body parts one and casing body parts two can also be connected and fixed by any in welding, riveted joint, thread connecting mode.
The beneficial effects of the utility model:
By the integral type casing of two-tube for traditional flat firearms being designed to the combined type casing of split, this combined type casing comprises casing body parts one and casing body parts two, casing body parts one and casing body parts two are individually processed, solve a difficult problem for integral type casing processing technology difference, improve crudy simultaneously, be conducive to bulk production; Casing body parts one and casing body parts two are respectively arranged with the first locating slot cooperatively interacted and tenon, the second locating slot and guide pad guarantee that casing body parts one and casing body parts two are located reliably.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 4, Figure 5 and Figure 6, combined type casing, comprises casing body parts 1, is connected with casing body parts 22 below described casing body parts 1.The medial surface of the bottom of described casing body parts one offers the first gathering sill 3, the tail end on the top of casing body parts one offers the second gathering sill 4; The front end of described casing body parts two is provided with two tenons 5 coordinated with the first gathering sill on casing body parts one, and the rear end of casing body parts two is provided with the guide pad 6 coordinated with the second gathering sill on casing body parts one.In the present embodiment, described casing body parts 1 and casing body parts 22 are connected and fixed by connecting pin bottom casing 7 and casing afterbody connecting pin 8.
Described casing body parts one and casing body parts two can also be connected and fixed by any in welding, riveted joint, thread connecting mode.
Process and the assembling process of combined type casing of the present utility model are as follows: the structure first processing casing body parts one and casing body parts two, and first casing body parts one will process hit pinhole, Breech block groove, gathering sill etc. and close weight structure.Casing body parts two process the structure coordinated with casing body parts one.Push casing body parts two to casing front end along guide-track groove from casing afterbody coordinate with casing body parts one, after both are combined, load connecting pin and casing afterbody connecting pin bottom casing, four parts are combined into an entirety.
