Five-axle power head used for numerical control milling machine

Abstract

The invention discloses a five-axle power head used for a numerical control milling machine, which belongs to the technical field of a five-axle power head. The five-axle power head comprises a main chassis and an auxiliary chassis, wherein the main chassis is installed on the ram of the numerical control milling machine; the auxiliary chassis and the main chassis are installed together; a driving shaft connected with the connection taper shank of the numerical control milling machine is arranged in the main chassis; a center shaft for installing a cutter is installed in the auxiliary chassisin a rotation mode; the center shaft is in drive connection with the driving shaft by an actuating device; a C-shaft throw device is arranged between the auxiliary chassis and the main chassis; and the main chassis and the auxiliary chassis are hinged by the C-shaft throw device; a cutter beating device is arranged between a driving shaft and a center shaft, is arranged in the main chassis and ispositioned on the axis of the driving shaft. The five-axle power head used for a numerical control milling machine has the advantages of simple structure, good stability and low cost, is convenient to use and can be widely applied to the numerical control milling machine.

Description

technical field [0001] The invention relates to the technical field of numerical control milling machines, in particular to a five-axis power head of a numerical control milling machine suitable for processing pentahedrons. Background technique [0002] CNC milling machines are widely used in the field of mechanical processing, and plane processing is more commonly used. Some CNC milling machines are equipped with a five-axis power head on the ram, which expands the processing range of the tool and can process arc surfaces or polyhedrons, reducing the need for re-clamping. times, thereby reducing machining errors. [0003] However, the current five-axis power head of the CNC milling machine has a complex structure and high cost. When in use, due to the large milling force, the milling force affects the stability of the five-axis power head, making the tool of the five-axis power head shake, which directly affects the performance of the CNC milling machine.

[0003] However, the current five-axis power head of the CNC milling machine has a complex structure and high cost. When in use, due to the large milling force, the milling force affects the stability of the five-axis power head, making the tool of the five-axis power head shake, which directly affects the performance of the CNC milling machine. Processing quality, and the five-axis power head itself does not have a knife device, so it is inconvenient to change the tool
