Problems solved by technology

This method is not only labor-intensive, but also labor-intensive, especially for workpieces with large diameters, manual graduations are not accurate, resulting in high manufacturing costs, low accuracy and precision
[0003] For example, the processing of the vertical ribs of the lower frame of the large hydroelectric generator set, the boring processing of the pin holes of the joint surface of the runner, the processing of the vertical ribs and grooves of the rotor bracket, etc., these large and extra-large parts often have a diameter of 10 Meters or more than 20 meters, weighing 300 tons or even more than 500 tons, traditional methods rely on flame baking, manual grinding, manual calibration, or use many gaskets for on-site adjustment, which is not only time-consuming, but also difficult to guarantee accuracy

Abstract

The invention relates to a separable combined turning / milling / boring machine. The separable combined turning / milling / boring machine is characterized by comprising a positioning shaft fixed in the position of the central axis of a workpiece to be machined, a beam comprising a cross beam, a power head arranged on the beam in a sliding manner and comprising a main driver, a power box and a cutting tool bit, an indexing detection device for detecting the angle of rotation of the beam, and an indexing control device for receiving information fed back by the indexing detection device and controlling the beam to stop at a specified angle, wherein the cross beam is horizontally and rotatably fixed on the positioning shaft; the power head is capable of moving in the horizontal and vertical directions. As the indexing detection device and the indexing control device are adopted to control indexing, the separable combined turning / milling / boring machine is high in indexing precision, convenient to operate, and full-automatic; the production efficiency is improved and the machining period is shortened; the separable combined turning / milling / boring machine is suitable for indexing machining and the like of large workpieces.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to an indexable combined turning, milling and boring machine. Background technique [0002] For the processing of evenly distributed holes or grooves on the end face or outer peripheral surface of large ring-shaped and ring-like workpieces, the turning-milling-boring machines of the prior art are usually manually measured and indexed or manually configured. This method not only consumes manpower, but also has high work intensity, especially for workpieces with large diameters, the manual graduation is not accurate, resulting in high manufacturing costs and low accuracy and precision. [0003] For example, the processing of the vertical ribs of the lower frame of the large hydroelectric generator set, the boring processing of the pin holes of the joint surface of the runner, the processing of the vertical ribs and grooves of the rotor bracket, etc., these large and extra-large pa...
