Abstract
Description
Technical Field
[0001] The invention relates to a boring tool device for processing deep holes, which can be widely used in the deep hole processing process of boring machines. Background Art
[0002] When existing boring machines are used to process deep holes in large parts, the boring bar is prone to bending and shaking due to the large diameter and deep length of the inner hole of the part, which can easily cause the inner hole of the processed part to fail to be precisely machined to the required size. Summary of the invention
[0003] The object of the present invention is to provide a boring tool device for deep hole machining of large parts with high part machining accuracy.
[0004] In order to achieve the above-mentioned purpose, the present invention provides a boring tooling device for processing deep holes, including a boring machine table for clamping a workpiece, a boring bar installed on the boring machine table and capable of both left and right movement and rotation, an auxiliary support installed on the tail end of the boring bar through an inner hole, a cutter disc connected to the boring bar key through a plurality of flat keys, a plurality of fastening screws for axial positioning on the flat keys, a connecting plate fastened to the end face of the boring bar head through a boring bar fastening screw, and a boring machine tool holder fastened to the connecting plate through a boring machine tool holder fastening screw.
[0005] The invention discloses a boring tool device for processing deep holes. The boring bar is an extended long boring bar and is used for processing deep holes.
[0006] The invention discloses a boring tool device for processing deep holes. The cutter disc is a large cutter disc with an increased diameter and is used for processing large holes.
[0007] The invention discloses a boring tooling device for processing deep holes. The boring bar has one end connected to a boring machine tool rest and the other end installed on an auxiliary support.
[0008] The boring tooling device for processing deep holes of the present invention has the following working principle: when processing a long inner hole with a large diameter, the cutter disc is installed on the boring bar, one end of the boring bar is connected to the boring machine tool holder, and the other end is installed in the inner hole of the auxiliary support. The boring bar rotates with the boring machine tool holder and moves in the front and rear directions in the auxiliary support. During processing, the present invention has a large cutter disc diameter and a long boring bar length, so that the inner hole diameter of the processed part is large and the length is deep, thereby realizing the processing of deep holes of large parts.
[0009] Compared with the prior art, the boring tooling device for processing deep holes of the present invention adopts auxiliary supports and boring machine tool holders to support and position the two ends of the boring bar. At the same time, the cutter head is key-connected and positioned with the boring bar fastening screws in the axial and circumferential directions, thereby ensuring the rigidity of the boring bar, avoiding the bending and chattering of the boring bar, and achieving high part processing accuracy.
[0010] In summary, the boring tooling device for processing deep holes of the present invention can realize deep hole processing of large parts with high part processing accuracy. BRIEF DESCRIPTION OF THE DRAWINGS
