Using method for universal angle milling head

Abstract

The invention discloses a using method for a universal angle milling head, which comprises the following steps of: 1, manufacturing a machining program of a workpiece, and selecting a cutter locationpoint as a sphere center of a cutter when the program is output; 2, aligning and installing a standard square block on a machine tool, and determining the center point of the upper surface of the square block as the origin of a reference coordinate system; 3, installing the workpiece, measuring the position difference between the original point of the workpiece coordinate system and the original point of the reference coordinate system, taking the position difference as the offset value of the original point of the reference coordinate system and the original point of the workpiece coordinatesystem, and recording the offset value in a numerical control system for subsequent conversion from the original point of the reference coordinate system to the original point of the workpiece coordinate system; 4, importing the machining program into a machine tool, and manually setting the angles of the two rotating shafts on the universal angle head as cutter shaft angles specified in the machining program; 5, setting a tool on the original point of the reference coordinate system by taking the sphere center of the tool as a tool setting point, and establishing a current reference coordinate system; and 6, starting a machining program, and starting machining. According to the invention, the influence of angle deviation of manually operating the universal head on machining is eliminated.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a method for using a universal angle milling head. Background technique [0002] At present, the universal angle milling head is equipped on the ordinary three-axis CNC milling machine, which expands the technological range of the ordinary three-axis CNC machine tool, so that it has 3+2 five-axis positioning processing capabilities, which is very suitable for processing all kinds of heavy weight, large volume, etc. The large-scale molds and models of secondary positioning have broad application prospects, especially in industries with large-scale model processing requirements such as automobiles, wind power, and yachts. [0003] like figure 1 As shown, the universal angle milling head mainly includes a tool handle 1 , a first indexing dial 2 , a second indexing dial 4 , a first rotating shaft 3 , a second rotating shaft 5 and a tool 6 . [0004] At pre...

[0008] (3) According to the angle positioning requirements in the workpiece processing program, use the probe system to assist the angle positioning of the two rotation axes of the universal angle milling head to be strictly consistent with the program angle requirements. This step is difficult to operate

In practical applications, the indexing of the universal angle milling head will be matched and aligned with the program angle by means of the probe system. This operation is complicated to implement and the process is long, and the use of the probe system increases the implementation cost.
