Induction ring tracking device of rotary lathe

Abstract

The invention relates to an induction ring tracking device of a rotary lathe, in particular to a device used for guaranteeing the shape and size accuracy of a milling surface when a workpiece is milled, and belongs to the technical field of machining equipment. The induction ring tracking device of the rotary lathe comprises two bases respectively fixed at two sides of a milling power head of a machine frame, wherein each base is connected with an eddy-current sensor through a sensor support frame, an arc standard ring is arranged right in front of the two eddy-current sensors and is connected with cushion plates which are arranged at intervals, a magnet is arranged in each cushion plate, the upper portion and the lower portion of each cushion plate are respectively connected with a first adjustment bolt, and the standard ring is pressed vertically and tightly through the upper first adjustment bolt and the lower first adjustment bolt. A lateral surface of each cushion plate is connected with two second adjustment bolts, and the standard ring is pressed horizontally and tightly through the second adjustment bolts. The induction ring tracking device of the rotary lathe is ingenious, compact and reasonable in structure, and is capable of guaranteeing the shape and size accuracy of the milling surface when the workpiece is milled through tracking feedback of the eddy-current sensors.

Description

technical field [0001] The invention relates to an induction ring tracking device of a rotary machine tool, specifically used to ensure the shape and size accuracy of a milling surface when a workpiece is milled, and belongs to the technical field of mechanical processing equipment. Background technique [0002] There are high processing requirements for the surface of large disc workpieces. In order to ensure the processing flatness and roughness requirements of the workpiece surface, two sets of travel wheel mechanisms are respectively installed on both sides of the frame, and the travel wheel height adjustment mechanism and tracking detection device ensure the flatness of the workpiece surface. [0003] In the prior art, the induction tracking device is installed close to the rotating center frame. Since the rotary machine tool is a large-scale machine tool for milling super-large diameter workpieces, the small error detected on the ring close to the center position will...

AI Technical Summary

Problems solved by technology

Since the rotary machine tool is a large machine tool for milling super-large diameter workpieces, the small error detected on the ring close to the center position will be magnified many times when it reaches the end of the milling power head, resulting in low milling flatness, which cannot ensure the milling of the workpiece The shape and dimensional accuracy of the milling surface directly affect the performance and life of the machine tool
