Abstract

The invention discloses a fast positioning device applied to an automatic feeding drill. The fast positioning device comprises a screw frame (4) used for being connected with an external screw device and providing feeding pushing force for the fast positioning device during working. A front section guiding assembly (2) is used for achieving the slight movement of a hole forming cutter in the axial direction. A rear section locking assembly (3) is used for achieving connection between a straight handle pneumatic drill body and the front section guiding assembly (2) and matched with the screw frame (4) through a universal bearing, it is guaranteed that the external screw device stably transmits the feeding pushing force to the hole forming cutter, the hole forming cutter is guided through the front section guiding assembly (2), and it is guaranteed that under the situation that the cutter is subjected to large axial force and torque, a pneumatic drill is prevented from playing and swinging in the axial center line direction, and the task of drilling laminated materials is smoothly finished. By means of cooperation of the front section guiding assembly (2) and the rear section locking assembly (3), the pneumatic drill carries out stable feeding in the drilling process, and cutter clamping does not exist.

Description

technical field [0001] The present invention relates to a rapid positioning device, more particularly, relates to a rapid positioning device for hole positions applied to automatic feed drills. The device is especially suitable for the high-quality, high-efficiency and low-cost automatic hole-making process of carbon fiber composite materials and titanium alloy laminated materials. The invention belongs to the technical field of cutting processing technology of difficult-to-machine materials and equipment parts. Background technique [0002] Automatic feed drilling equipment is an automatic hole-making device widely used in aircraft assembly technology. The automatic feed drill can use different speeds to make holes at a certain feed rate. Since there is no stopping and decompression during the hole making process, the hole making tool can remain sharp for a long time, and there is no chattering site when the hole penetrates, thus reducing the possibility of the hole makin...
