Abstract

The utility model provides a clamp for processing an eccentric circular arc on a lathe. According to the technical scheme, the clamp for processing the eccentric circular arc on the lathe comprises a mandrel, a fixed disk, screws, a movable disk, a gasket, a nut, a long key and a short key, wherein a long key slot and a short key slot are formed in the mandrel; the short key is arranged in the short key slot, and the short key slot is connected with the fixed disk through the short key; the long key is arranged in the long key slot, and the long key slot is connected with the movable disk through the long key; the gasket is arranged on the right side of the movable disk and locked and positioned on the mandrel by the nut; four uniformly distributed eccentric holes are formed in each of the fixed disk and the movable disk, and the eccentric distances of the eccentric holes are equal to the eccentric distances of workpieces; the workpieces are arranged in the eccentric holes, and two ends of each workpiece are compressed and positioned by the screws; and the left end of the mandrel is clamped on a three-jaw chuck of the lathe, and the right end of the mandrel is propped by the tip of a tailstock of the lathe. The clamp has the benefits as follows: the structure is simple, the use is convenient, the production efficiency is high, and the quality is good.

Description

On a kind of lathe, process eccentric arc fixture
Technical field
The utility model relates on a kind of lathe and processes eccentric arc fixture, belongs to machining clamping tool technical field.
Background technology
The job key of some machines and the section configuration of brake key are eccentric arc, as shown in Figure 3, Figure 4, its eccentric throw is D, and eccentric arc radius is R, processing to these class machine components, be all to carry out on vertical knee-type milling machine, but this processing method is difficult to reach drawing requirement, percent defective is high all the time, process velocity is slow, productivity ratio is low, and operator wants continuous tool setting displacement, thereby feels more tired.
Summary of the invention
The purpose of this utility model is just to provide on a kind of lathe and processes eccentric arc fixture, for addressing the above problem.
The technical solution of the utility model is: on a kind of lathe, process eccentric arc fixture, comprise axle, fixed disc, screw, mobile disk, pad, nut, long key and short key, axle is provided with long keyway and short keyway, described short keyway is provided with short key and is connected by itself and fixed disc, described long keyway is provided with long key and is connected by itself and mobile disk, mobile disk right side is provided with pad, described pad is by nut locking positioning in axle, on fixed disc and mobile disk, be respectively equipped with four equally distributed eccentric orfices, the eccentric distance of described eccentric orfice equals the eccentric throw of workpiece, in described eccentric orfice, be provided with workpiece, workpiece two ends are located by screw in compression, axle left end is clamped on lathe three-claw chuck, axle right-hand member withstands by tail stock is top.
The beneficial effects of the utility model are: simple in structure, easy to use, production efficiency is high, quality is good.
