Abstract
Description
technical field
[0001] The invention belongs to the technical field of aero-engines, in particular to a clamp for multi-angle drilling. Background technique
[0002] In the process of machining inclined holes of aeronautical engine pipe joints, due to the inconsistency of the inclination angles of the holes, the current machining methods are generally completed by numerical control equipment programming, or multiple sets of tooling are designed and processed on ordinary drilling machines. However, although the method of CNC machining is convenient, there are problems of small number of CNC equipment and low utilization rate of machine tools. In the application process of special fixtures, due to the difficulty in adjusting the angle of the fixture, the clamping is unstable or due to tooling manufacturing errors or datum conversion errors, the processing of parts is difficult, and even the processing is unqualified. Therefore, there is an urgent need for a fixture for multi-...
