Adjustable floating reamer integrated with universal adjustment for roughing and finishing

Abstract

The present invention relates to tool bar tooling equipment for processing holes, in particular to a universally adjustable floating reamer for rough and fine machining, including universally adjustable tool bar, roughing reamer and floating reamer, and universally adjustable The tool bar includes a tool bar handle, a universal joint and a tool bar cover. The tool bar handle and the tool bar cover are respectively pinned to the two ends of the universal joint; One end has a limit slot; the floating reamer is accommodated in the limit slot and can float in the limit slot, and the rough machining reamer limits the position of the floating reamer while processing holes through the cutting edge. The invention eliminates various errors in the machine tool equipment system, the manufacturing error of the cutter bar and the deformation error, improves the machining accuracy of the hole, and thus completely solves the problem that the machine tool spindle cannot approach the hole due to low equipment precision and special hole position, and the tool bar protrudes too long. Hole processing accuracy quality problem; the present invention integrates rough and fine reaming processing holes, greatly improving the production efficiency of hole processing.

Description

technical field [0001] The invention relates to a cutter bar tooling device for machining holes, in particular to a universally adjustable floating reamer for rough and fine machining. Background technique [0002] Such as Figure 10 As shown, there is a pin hole 28 for the positioning partition on the MCL (horizontally split) casing 27 abdominal cavity ring ribs. This pin hole 28 is at the bottom of the casing 27 abdominal cavity. According to the size of the casing 27, generally the positioning pin The hole 28 is between 600mm and 1000mm away from the split surface 29 . Due to the limited working space in the abdominal cavity of the casing 27, the main shaft of the equipment cannot be extended into the interior for processing, so it can only be processed with the help of an extended tool bar; due to manufacturing errors in the extended tool bar, there is an error in the accuracy of the equipment, and the positioning pin hole 28 cannot reach the drawing after processing.
