Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of machining technology, more particularly to a high rigidity angle milling head suitable for machining the inner side of small-aperture and deep parts. BACKGROUND

[0002] The angle milling head is a machining tool. After the angle milling head is installed on the machine tool, the center line of the cutter can be angled with the center line of the spindle to process the workpiece. Using the angle milling head, the machining range and adaptability of the machine tool can be increased without changing the structure of the machine tool, so that some machining that is difficult to be completed by traditional methods can be realized, the number of repeated clamping of the workpiece can be reduced, and the machining precision and efficiency can be greatly improved. However, when the conventional angle milling head is used to machine the inner side of a hole with a small aperture and a great depth, the head of the angle milling head is too large and the connecting rod is too short, so that the side milling head cannot enter the hole, and thus the inner side of the hole cannot be machined. Alternatively, the front connecting rod of the angle milling head is lengthened to enter the deep hole for machining. However, the lengthened rod is too long, which results in insufficient rigidity of the angle milling head during machining, and the cutter shakes during machining, so that the precision of the part cannot be guaranteed.
