Tool setting method of vertical lathe

Abstract

The invention discloses a tool setting method of a vertical lathe, the vertical lathe is provided with a main shaft, a horizontal guide rail and a tool rest connected to the horizontal guide rail, the tool rest is provided with a machining tool capable of moving in the vertical direction, and the tool setting method comprises the steps that S1, the relation between the initial angle of the lathe and the angle of a tool setting piece is determined; s2, the angle relation is transferred to a main shaft reference datum piece; s3, measuring the angle relation between the reference surface of the workpiece mounted on the table surface of the main shaft and the reference surface of the reference datum piece to obtain a correction angle of the reference datum piece; and S4, the correction angle is input into a machining program of the vertical lathe. The tool setting method of the vertical lathe is suitable for machining non-rotational-symmetry workpieces, and the angular tool setting positioning problem of the non-rotational-symmetry surface-shaped machining workpieces is solved. The method is simple, feasible, easy to implement, low in cost and capable of meeting the high-precision machining requirement.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a tool setting method for a vertical lathe. Background technique [0002] The off-axis paraboloid is a kind of free-form surface. The off-axis paraboloid mirror has a wide application prospect in the terahertz and infrared bands. For the processing of the off-axis paraboloid, coordinate transformation can be used to make its geometric center coincide with the origin of the global coordinate system and use The datum plane is horizontal, so the machining of off-axis paraboloids can be converted to the machining of non-rotationally symmetrical surfaces. [0003] The vertical lathe is a large-scale mechanical equipment, which is used to process large and heavy workpieces with large radial dimensions and relatively small axial dimensions, and complex shapes, such as cylindrical surfaces and end surfaces of various discs, wheels, and sleeves. At present, the traditional tool setting...

Problems solved by technology

At present, the traditional tool setting method of vertical lathes is to perform tool setting in the front, rear and left and right directions, but this tool setting method is only suitable for machining rotationally symmetrical workpieces, while for non-rotatively symmetrical workpieces, only the front, rear and left and right directions are used. The tool setting cannot be processed (due to the asymmetry of the machined surface shape), so there is an urgent need for a new tool setting method to solve the processing of non-rotational symmetrical surface workpieces.
