Problems solved by technology

[0003] 1) Due to the manufacturing error of the machine tool, tool handle, and reamer, or when the accuracy of the machine tool and tool handle decreases, the reamer often has a large radial runout (different axis) on the machine tool spindle, resulting in an oversized reaming hole, and further needs Resharpening the reamer solves the problem, which impacts production
[0004] 2) Due to the uncontrollable radial runout of the reamer on the machine tool, the reamer diameter design of

Abstract

The floating cutter handle for reaming comprises a floating device and a cutter handle, the floating cutter handle comprises a cutter connecting sleeve, a cutter handle connecting sleeve and a connecting pin, the right portion of the cutter handle connecting sleeve is installed on the left portion of the cutter handle and rotates synchronously with a handle, and the left portion of the cutter handle connecting sleeve is further provided with an axial connecting hole; the right portion of the cutter connecting sleeve is assembled in the connecting hole in a clearance fit mode and connected with the clamping position through a connecting pin arranged in the radial direction, so that the cutter handle connecting sleeve and the cutter connecting sleeve rotate synchronously. The connecting pin is in clearance fit with the cutter connecting sleeve and is in interference fit with the cutter handle connecting sleeve; a gap is formed between the right end of the cutter connecting sleeve and the bottom of the connecting hole, and an axial mounting hole connected with a reamer is formed in the left end of the cutter connecting sleeve. The reamer has the advantages of simple structure, accurate processing, prolonged service life and the like.

Description

technical field [0001] The invention relates to the technical field of machine tool processing, in particular to a floating tool holder for reaming and a method for using the same. Background technique [0002] At present, ordinary tool handles are generally used to clamp reamers to rigidly ream holes on machine tools, and there are the following problems: [0003] 1) Due to the manufacturing error of the machine tool, tool handle, and reamer, or when the accuracy of the machine tool and tool handle decreases, the reamer often has a large radial runout (different axis) on the machine tool spindle, resulting in an oversized reaming hole, and further needs Resharpening the reamer solves the problem, which affects production. [0004] 2) Due to the uncontrollable radial runout of the reamer on the machine tool, the reamer diameter design of the rigid reamer is usually small, [0005] Affect the life of the reamer. [0006] 3) Rigid reaming usually cannot correct the deviatio...
