Five-shaft machining center angle head fixing device

Abstract

The invention relates to the technical field of angle head fixing devices, and discloses a five-shaft machining center angle head fixing device. The five-shaft machining center angle head fixing device is characterized by comprising four parts including a positioning element, a fixing element, clamping elements and locking elements; the positioning element is a positioning block; the fixing element is a fixing ring; the clamping elements are two positioning screws, and the locking elements are six locking screws; the inner groove size of the fixing ring is designed according to the machine tool main shaft size; the two work faces of the positioning block are tightly connected with the fixing ring and an angle head correspondingly; the fixing ring is fixed to a main shaft of a machine tool;the main shaft is tightly screwed through the locking screws, and the tight screwing degree of the locking screws is determined on the basis that the fixing ring is not tightly locked and does not downwards slide; and the positioning block sleeves a positioning column of the angle head, and the main shaft is oriented to be aligned with a cutter handle groove of the angle head. The phenomenon of interference during shaft neck side milling machining is avoided in the aspect of the structure, and the clamp positioning precision is improved.

Description

technical field [0001] The invention relates to the technical field of angle head fixing devices, and more specifically, relates to an angle head fixing device for a five-axis machining center. Background technique [0002] The overall blisk has the characteristics of complex structure, narrow channel, large bending range, thin blade, and easy deformation, but it requires high precision and is difficult to process. Since the journal of the blisk is in the center of the part, and the size of the blade is relatively large, when using a five-axis machining center to process characteristic structures such as the slot hole on the outer circle of the journal, the tool and the blade of the blisk will collide and interfere, which will affect the processing quality . Based on this, a common practice in machining is to install an angle head. The angle head is a machine tool accessory that allows the tool rotation centerline to form a certain angle with the spindle rotation centerlin...

AI Technical Summary

Problems solved by technology

The traditional angle head fixing method has a large gap. When the material to be processed is hard and the cutting force of the tool is too large, the tool will bend and deform due to the force and generate vibration, resulting in low processing efficiency and processing accuracy.

[0003] When the five-axis machining center processes complex parts with lateral journals, the overcut interference and collision interference between the tool and the parts often occur, which affects the processing quality
