Definitions
- the invention relates to a rifle with a barrel releasably secured in the housing, the rear part of the barrel being surrounded by an inner cylindrical surface of the housing.
- shrink connections or screw connections are usually used for the connection of barrel and housing, especially with repeating rifles.
- Shrink connections can only be released to a very limited extent; screw connections are complex to manufacture. Above all, however, screw connections are not suitable for housings made of materials other than steel, for example aluminum or light metal alloys.
- the clamping elements are n large series manufactured standard parts, therefore very closely tolerated and still cheap, so that a very precise centering is possible. They lie on the outside over a large area on the inner wall of the housing, so that a reliable frictional engagement can be achieved with a relatively low load on the housing. Since the housing does not need any slots or extensions, it is light and can also be made from light metal.
- the thread for the clamping nut on the barrel can absorb considerable forces, since the barrel consists of a hardened or tempered material.
- the nut is also made of a high-strength material and therefore requires very little space.
- the rear part of the barrel has a conical outer surface and the clamping element is an clamping sleeve that is alternately slotted from the front and rear.
- Such clamping sleeves are known in machine tools for clamping workpieces with a central bore. They are also cheap and very precise standard parts with precisely known properties and are particularly easy to assemble.
- pairs of clamping rings with conical surfaces facing each other are arranged between the clamping nut and a collar of the barrel.
- the collar allows an exact axial fixation of the barrel.
- Fig.l A horizontal section through part of a rifle provided with the invention in a first embodiment
- Fig.2 Like Fig.l, but in a second embodiment.
- FIG. 1 a part of the housing is shown and designated 1.
- a rear inner wall 2 of smaller diameter represents, for example, the guide for a cylinder lock (not shown). This is followed by a cylindrical inner surface 3 with a larger diameter, which extends forwards to the front housing end, which is no longer shown.
- a barrel 5 is fastened in a manner according to the invention. Only its rear part is shown. At 6 begins a thread cut on the rear part of the barrel 5, which extends as far back as necessary, but better not to a radial annular surface 8 of a collar 7. This collar 7 has a circumferential groove 9 for a purpose specified later. A cartridge chamber wall can then follow the collar 7. Essential is the thread 6 on the barrel and the collar 7, as well as the cylindrical inner surface 3 of the housing.
- Clamping rings 11 and as many clamping rings 12 are provided.
- the clamping rings 11 are slotted so that they can be easily expanded radially. Its outer boundary surface is cylindrical, its inner boundary surface is conical.
- the respective complementary rings 12 can be slotted, have a cylindrical inner surface and a conical outer surface at the same angle as the rings 11. The number of such ring pairs can be selected according to the requirements.
- a clamping nut 13 which can be screwed onto the thread 6 of the barrel 5 and presses the clamping rings 11, 12 against the ring surface 8 of the collar 7.
- the clamping rings 11 expand, the cylinder surfaces of which are pressed against the cylinder surfaces of the barrel and housing. They create a tight and precise frictional connection with respect to both the barrel and the housing.
- the clamping nut 13 still has recesses for a pipe spanner at the front and can be secured by means of a threaded pin 15.
- a position block 16 to which a holding claw 17 is screwed. This engages through an opening 18 on the housing 1 into the groove 9 in the collar 7.
- FIG. 2 shows another embodiment, same parts have the same reference numerals. It differs from the previous one in that a clamping sleeve 20 is provided instead of the ring pairs 11, 12.
- This adapter sleeve is of the construction known from mandrels in machine tool construction: it has slots 21, 22 which run alternately from the front and from the rear over a large part of its length, which give it radial extensibility and has a conical inner wall 23 which is on an equally conical one Outer surface 24 of the barrel sits. It is pushed by the clamping nut 13, here not against a stop, but onto the conical outer surface of the barrel 24 and expands in the process. This creates a firm frictional connection again.
