Abstract

The invention provides a floating-type multifunctional BTA deep-hole cutter system based on self-guiding, and belongs to the technical field of deep-hole machining cutters. The system comprises a BTAcutter head and a drill rod, wherein the BTA cutter head and the drill rod are connected through a floating connection device. The floating connection device comprises a cutter head connecting piece,a cutter bar connecting piece, balls, an upper end cover, a rubber ring, vibration attenuation blocks and auxiliary guiding strips, wherein the front end of the cutter head connecting piece is connected with the BTA cutter head, the cutter head connecting piece is provided with upper end cover mounting holes, jet flow holes and cutting liquid grooves I, the cutter bar connecting piece is sleeved with the cutter head connecting piece and is provided with arc grooves, the rear end of the cutter bar connecting piece is connected with the drill rod, the balls are put in the arc grooves, the upperend cover is assembled in the upper end cover mounting holes, the rubber ring is arranged between the cutter head connecting piece and the cutter bar connecting piece, and the vibration attenuation blocks and the auxiliary guiding strips are assembled on the outer cylinder surface of the cutter head connecting piece. The BTA deep-hole cutter system can automatically eliminate the influence of bending and vibration of the drill rod on a self-guiding system in the BTA cutter deep-hole machining process, and more reasonable position vibration attenuation, better chipping removal and a more coordinated self-guiding function are achieved.

Description

technical field [0001] The invention belongs to the technical field of deep hole processing cutters, and specifically discloses a self-guiding floating multifunctional BTA deep hole cutter system. Background technique [0002] Due to the special self-guiding properties, deep hole processing can process deep holes with a large aspect ratio. With the innovation of emerging industries and high-tech technologies, the processing quality requirements for functional deep hole parts such as assembly, sealing, and reference guidance higher and higher. However, due to the inherent limitations of the special closed and narrow space and the weak rigidity system, it will cause the bending deformation of the drill pipe system in the drilling part during the processing, making it difficult to guarantee the hole size, straightness and roundness in mass production. Consistency and accuracy requirements. Therefore, it is urgent to break through the limitations of the inherent properties of ...
