Abstract

The invention relates to a clamp for multi-angle drilling. The clamp comprises a base, a rotating support and a pressing mechanism, wherein the rotating support comprises a rotating base, a plug pin,a drill plate and a rotating shaft, the rotating shaft sequentially penetrates through the rotating base and the base and can rotate around the rotating base, the other end of the rotating shaft is connected with a handle, the drill plate is installed on the rotating base, a through hole corresponding to a hole to be machined is formed on the drill plate, a pressing mechanism comprises a pressingblock I, a pressing block II and a supporting block, a screw sequentially penetrates through the pressing block I and the pressing block II to fix the pressing block I and the pressing block II on anupper inclined surface of the rotating base, a positioning groove is formed on the pressing block II, the supporting block is placed in the positioning groove to support the pressing block I, an anglehole with the same angle as a to-be-machined hole of a machined workpiece is formed in the rotating base, a through hole corresponding to the angle hole is formed in the base, and a plug pin is inserted into the corresponding angle hole and the through hole to achieve rapid positioning of the angle. The clamp can reduce dependence of a pipe on numerical control equipment, improve machining efficiency and simplify operation steps.

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-...
