Detailed Description

In order to facilitate the understanding of the technical solutions of the present invention for those skilled in the art, the technical solutions of the present invention will be further described with reference to the drawings attached to the specification.

The terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

Referring to fig. 1, the embodiment discloses a composite reamer for processing a cylinder bulkhead hole, which includes a taper shank 1, a cutter body 2, a composite cutter 3, and a connecting rod 4.

Referring to fig. 1 and 3, the taper shank 1 is specifically a "morse taper shank" and is effectively used for static cooperation so as to facilitate accurate positioning, the front end of the taper shank 1 is fixedly connected with the cutter body 2, and the rear end of the taper shank 1 is provided with a connecting port 11 parallel to the cutter body 2.

In this embodiment, the taper shank 1 and the cutter body 2 are of an integrated structure.

Referring to 1-2, the cutter body 2 is integrally formed by welding two 'cylinders', and is of an integrated structure and comprises a reamer body 21 and an expansion cutter body 22, a plurality of compound cutters 3 are welded on the outer side of the cutter body 2 at equal intervals, each compound cutter 3 comprises an expansion cutter 31 and a finish reamer 32, the expansion cutters 31 are welded on the top end of the outer side of the expansion cutter body 22 at equal intervals, and the finish reamers 32 are welded on the outer side of the top end of the reamer body 21 at equal intervals.

In this embodiment, every group expands sword 31, finish reamer 32 and all is step compound welding, expands sword 31 in the front, carries out the reaming, and finish reamer 32 is at the back, and feed forward, finish reamer 32 reams to the finished product size to the vexed head hole, once only accomplishes processing, has improved work efficiency greatly.
