Description

Technical Field

[0001] The utility model relates to the field of machinery, in particular to a two-way output integrated shaft angle head. Background Art

[0002] Angle head is a machine tool accessory. After the machine tool is equipped with an angle head, the tool rotation centerline can be angled with the spindle rotation centerline to process the workpiece. Originated in Europe, it is now widely used in various fields of mechanical processing such as aviation, automobiles, and molds. Using an angle head can increase the processing range and adaptability of the machine tool without changing its structure, making it possible to achieve some processing that is difficult to complete with traditional methods, and can reduce repeated clamping of workpieces, improving processing accuracy and efficiency.

[0003] The advantage of a two-way output angle head is that tools can be installed on both sides, but due to the large outer diameter of the ER collet nut, the gear shaft diameter cannot enter the middle from both ends. In the past, when manufacturing a two-way angle head, the two shafts were generally connected and the middle screw was locked. This structure has a low processing strength due to the existence of a matching gap, which cannot meet the processing of high-precision parts and has a high failure rate. Utility Model Content
