Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element to which the reference is made must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "disposed," "connected," and the like are to be construed broadly, and for example, "connected" may be either fixedly connected or detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The utility model relates to a rifling machine auxiliary fixture frock uses on the rifling machine, is as the auxiliary fixture frock use. As shown in fig. 1, the auxiliary fixture tool comprises a hoop I1 and a hoop II 2 which are used in a matched manner, wherein the hoop I1 and the hoop II 2 are of a split structure, and are sleeved on the outer wall of a part 5 to be processed in use and are connected together by using bolts.

As shown in fig. 1 and 2, the first hoop 1 is a semicircular sleeve structure, a connecting table 4 is integrally arranged at the end of the semicircular sleeve, and connecting holes are arranged on the connecting table 4 at intervals. The second hoop 2 is also of a semicircular sleeve structure, and screw holes are formed in two end faces of the semicircular sleeve. The connecting bolt passes through the connecting hole on the connecting platform 4 and then is in threaded connection with the screw hole. In a specific implementation, the hoop I1 and the hoop II 2 are formed by performing line cutting by using the same round sleeve. Generally, the hoop I1 and the hoop II 2 are made by molybdenum wire cutting, so that the processing deformation can be prevented.

As shown in fig. 1, 2 and 3, preferably, a plurality of reinforcing ribs 3 are provided at intervals on the outer circumferential surfaces of the hoop i 1 and the hoop ii 2. And further, the connection table 4 and the screw holes are provided at the position where the reinforcing bar 3 is located. The connection station 4 under this structure is actually several connection blocks. By adding the reinforcing ribs in the middle, the strength requirement is met, the weight is reduced, and the workpiece clamping difficulty is reduced.

In a specific implementation, the hoop I1 and the hoop II 2 are formed by performing line cutting by using the same round sleeve. Therefore, the outer diameters of the hoop I1 and the hoop II 2 are consistent, and the inner diameters of the hoop I1 and the hoop II 2 are also consistent.
