Multi-angle rotary drilling tool

Abstract

The invention discloses a multi-angle rotating type drilling tool, comprising an upper positioning plate, a lower positioning plate, an upper rotating jig frame, a lower rotating jig frame, a first lead screw, and a second lead screw; one end of each of the first lead screw and the second lead screw is fixedly connected through a connecting sleeve, and the other ends are respectively fixed in lead screw fixing holes on the upper positioning plate and the lower positioning plate at both ends of a processing piece; the upper positioning plate is externally fixed with the upper rotating jig frame through a connection bolt fixing hole and a connection bolt, the lower positioning plate is externally fixed with the lower rotating jig frame through the connection bolt fixing hole and the connection bolt; guide holes are arranged on the upper positioning plate and the lower positioning plate; the upper rotating jig frame and the lower rotating jig frame are equipped with magnetic drills at the position of the connection bolt fixing hole. The multi-angle rotating type drilling tool can guarantee the boring precision and meet the hole space as required in drawing, avoid welding, and repeated manufacturing of the jig frame, and reduce the bump risk to the machining face; the magnetic drill is convenient to position and the working efficiency of drilling can be improved.

Description

technical field [0001] The invention relates to a multi-angle rotary drilling tool. Background technique [0002] Before drilling the end face of the rudder blade casting, it is necessary to mark the hole position on the end face. Due to the various angle requirements of the end face hole position, the marking line positioning is difficult and the accuracy is not high; the end face is a machined surface, and the magnetic drill does not have a fixed welding position. It is necessary to set up a magnetic drill to fix the tire frame at a long distance. Due to the excessive distance, vibration will be generated during the magnetic drill processing, which will affect the hole processing accuracy; the original magnetic drill needs to occupy a crane for use; the internal drilling process of the rudder blade casting At the same time, it is necessary to weld two H-shaped steels on the outside to process the tire frame as a magnetic drill, but it is easy to cause bump damage on the en...
