Clamp locating device for lathe

Abstract

The invention discloses a clamp locating device for a lathe. The clamp locating device comprises a connector, a clamping port, clamping jaws and a movable block, wherein the connector is internally provided with a workpiece socket, and the right side of the connector is provided with a cone. The left end of the cone is provided with a circular chamfer located at the right end of the workpiece socket, the upper end of the clamping port is provided with a circumferential tooth, helical teeth are arranged above the clamping jaws and below the circumferential tooth, and anti-slip teeth are disposed under the clamping jaws. Connecting rods are connected to the right side of the movable block, and an operating panel is mounted on the right sides of the connecting rods. Compared with the existingordinary lathe clamp, the clamp locating device has the advantages of simple and reasonable structure, easy manufacture, low cost and wide application range. By means of the clamp locating device, production of batch parts can be uniform in process standard and good in size consistency. At the same time, the range of machined parts is greatly increased, and the practicality is improved.

Description

technical field [0001] The invention relates to the technical field of lathe fixture positioning, in particular to a lathe fixture positioning device. Background technique [0002] Lathe fixture refers to the fixture used to process the inner and outer rotary surfaces and end faces of the workpiece on the lathe. The positioning of the workpiece is a very important link during processing. [0003] At present, when using a three-grip chuck to clamp and produce a large number of parts on a machine tool, when using a three-grip chuck for positioning, only the positioning disc or hole parts can be processed, and the positioning ability of the fixture will decrease when processing some shaft parts. If the diameter of the machining shaft is smaller than the diameter of the inner hole of the three-grip chuck or the inner diameter of the spindle, positioning on the chuck will not work, and the protruding length is too long, and the workpiece will be offset due to insufficient rigidit...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a fixture positioning device for lathes to solve the problem of deviation caused by insufficient rigidity due to too long and small diameter of the workpiece during the positioning process on the general chuck proposed in the above-mentioned background technology, and it is difficult to ensure the accuracy. Failure to meet the original design requirements has greatly increased the scrap rate, reduced the work efficiency of operators, and failed to ensure normal production operations.
