Abstract

The invention relates to a platform-free line drawing device and a platform-free line drawing method for shaft and roller pieces. The device comprises a fixed rod, a base, a sliding fixed sleeve, a rotary rod, a rotary fixed sleeve, a workpiece center ejector pin, an outer reference line hook and an outer reference line sliding fixed sleeve, wherein the fixed rod is fixedly connected with the base; the sliding fixed sleeve is arranged on the fixed rod and is fixedly connected with the workpiece center ejector pin; the rotary fixed sleeve is arranged on the workpiece center ejector pin and is fixedly connected with the rotary rod; the outer reference line sliding fixed sleeve is arranged on the rotary rod and is fixedly connected with the outer reference line hook. The device has the advantages that the structure is simple; two line drawing devices are cooperatively used; a line can be drawn without a platform to judge whether the machining allowance meets machining requirements; moreover, the device is simple and convenient to operate, high in efficiency, low in cost and safe to operate.

Description

Technical field [0001] The invention relates to a platform-free line drawing device for shafts and rollers and a line drawing method, in particular to a device for free-platform line drawing to determine margins for machine-manufactured casting, forging shafts, rollers and other cylindrical multi-step workpiece blanks. Background technique [0002] The rough surface of large castings and forgings of shafts and rollers (more than 2 meters in length) is irregular, especially the rough surface of free press forgings is composed of multiple small planes, and it is often done by drawing lines on the platform to determine the workpiece margin without a foundation surface. Platform line drawing requires a large platform, which is costly. In addition, the steps of the platform line drawing method are cumbersome and require the cooperation of a large crane. Frequent turning of the workpiece takes a long time, and there are certain unsafe factors. Moreover, some casting production units do...
