Inner Rotation Thinning Spinning Tool

Abstract

The invention discloses an internal-rotation thinning spinning tool which comprises an outer shell, an adjusting device, a core sleeve, a core rod, a retainer, a cone-shaped column and two positioning circular truncated cones. One positioning circular truncated cone is fixedly arranged at the end of the core rod, the other positioning circular truncated cone is movably arranged on the core rod, and a pressed concave surface is formed between the positioning circular truncated cones; the cone-shaped column is movably arranged on the retainer and matched with the pressed concave surface in an abutted mode; the core sleeve is arranged on the outer circumferential surface of the core rod in a sleeving mode, and the end surface of the core sleeve is matched with the end surface of the positioning circular truncated cone movably arranged on the core rod in an abutted mode; the adjusting device is fixedly arranged on the outer shell and used by being matched with the core sleeve. The internal-rotation thinning spinning tool has the advantages of being simple in structure, longer in service life and higher in machining precision.

Description

technical field [0001] The invention belongs to the technical field of machining tools, and in particular relates to an inner-rotating thinning spinning tool. Background technique [0002] At present, some thin-walled pipe fittings are widely used in many occasions, such as the shielding sleeve on the shielding rod of the water pump, which is mainly set on the stator of the water pump to play the role of water cooling; in this case, the thinner the shielding sleeve The more water that passes through, the better the corresponding cooling effect. When the existing thinning tools are used to process the thin wall of some pipe fittings, the machining margin is limited, so that the precision of the finished product is low; there are also some thinning tools such as ball spinning tools, the balls on which are During operation, the point-to-point contact with the adjusting washer results in uneven stress on the adjusting washer; because of its small force-bearing surface, after lo...

Problems solved by technology

When the existing thinning tools are used to process the thin wall of some pipe fittings, the machining margin is limited, so that the precision of the finished product is low; there are also some thinning tools such as ball spinning tools, the balls on which are During operation, the point-to-point contact with the adjusting washer results in uneven stress on the adjusting washer; because of its small force-bearing surface, after long-term use, the contact point between the adjusting washer and the ball is easily damaged due to excessive force. Concave, not only causes the decline of machining accuracy, but also easily affects the service life; so it is necessary to improve
