Abstract

The invention discloses a positioning fixture for drum-like part turning. The positioning fixture comprises a support bar, wherein the front end of the support bar is coaxially provided with a support device which is inserted in the inner hole of a drum-like part when in use; the supporting device comprises a support wheel coaxially wound at the outer side of the support bar; a spoke structure used for supporting and fixing the support wheel is fixedly arranged between the support wheel and the support bar; spiral mounting holes, which extend along the radial direction of the support wheel, are uniformly and circumferentially distributed in the external ring surface of the support wheel; support studs are spirally assembled in the spiral mounting holes; and one end, away from the support bar, of each support stud is provided with a propping end which is used for propping against the inner hole wall of the drum-like part when in use. Holes are not required to be formed in the support bar, so that the strength of the support bar is not influenced, multiple spiral mounting holes can be formed in the support wheel, so that more support stud can be inserted so as to improve the supporting effect of the support device.

Description

Technical field [0001] The invention belongs to the technical field of machining tooling, and in particular relates to a positioning tool for turning processing of cylindrical parts. Background technique [0002] For cylindrical parts with a slender structure, a boring machine can generally be used for processing, and the processing cost of the boring machine is too high. In order to reduce the processing cost, a lathe is often used to turn the parts. When turning and processing slender cylindrical parts, sometimes it is necessary to process the craft belt first, and then place the center frame for processing after finding the reference. For some parts that cannot have craft belts, it is difficult to find the correct For processing. [0003] In the specification of the Chinese utility model patent with the publication number CN202070928U, a support device for processing thin-walled sleeves is disclosed. The support device includes a bearing seat, one end of the bearing seat is con...
