Deep hole processing online detection and correction device

Abstract

The invention discloses a deep hole processing online detection and correction device. The deep hole processing online detection and correction device is characterized in that an inspection hole is formed between a chip removal hole of a drill rod and an outer circle, an internal fixation frame provided with an internal laser source and a position-sensitive detector is arranged at corresponding positions on a drill bit and the inner end of the inspection hole, an external fixation frame provided with an external laser source and an angle-sensitive detector is arranged on the outer end of the inspection hole of the drill rod, the angle-sensitive detector corresponds to the internal laser source, and the position-sensitive detector corresponds to the external laser source; and radial expansion pieces are distributed along the circumferential direction of the drill bit, and axial expansion pieces are arranged while avoiding a circular groove space of the internal fixation frame between the drill bit and the drill rod. According to the deep hole processing online detection and correction device, the internal laser source and the external laser source transmit laser, positions and angles of the drill bit in a machining process are detected online, and the positions and angles of the drill bit are adjusted by virtual of a radial expansion piece and an axial expansion piece, so that the problems that drilling deflection can not be observed and correction can not be timely carried out are solved.

Description

technical field [0001] The invention belongs to the technical field of deep hole processing, and in particular relates to an online detection and deviation correction device for deep hole processing. Background technique [0002] Deep hole machining is complex and special, and it is difficult to observe the machining parts and tool conditions. The machining process is affected by many factors such as tool holder deformation, system chatter, workpiece material, drill parameters, cutting parameters, oil pressure, and difficulty in chip removal. The axis of deep hole parts often deviates. Once the deviation reaches a certain level, the straightness error of the axis of the deep hole parts will change sharply. Low product precision, unqualified quality and other adverse consequences. Since deep hole processing serves the equipment manufacturing industry, the quality of deep hole workpieces directly affects the development of the equipment manufacturing industry, and also limit...
