Adjustable floating reamer integrating universal adjusting, rough machining and finish machining

Abstract

The invention relates to cutter and cutter bar tool equipment for machining a hole, in particular to an adjustable floating reamer integrating universal adjusting, rough machining and finish machining. The adjustable floating reamer comprises a universal adjusting cutter bar, a rough machining reamer and a floating reamer, wherein the universal adjusting cutter bar comprises a cutter bar handle, a universal joint and a cutter bar sleeve, and the cutter bar handle and the cutter bar sleeve are respectively in pin connection with two ends of the universal joint; one cutter bar end of the rough machining reamer is connected to the cutter bar sleeve in an inserting manner, one cutting edge end of the rough machining reamer is provided with a limiting groove; the floating reamer is contained in the limiting groove and can float in the limiting groove, and the rough machining reamer is used for limiting the floating reamer while being used for processing the hole through the cutting edge. According to the adjustable floating reamer disclosed by the invention, various error such as the cutter bar manufacturing error and the deformation error in a machine tool equipment system can be removed, the hole machining accuracy is increased, and thus the quality problems that due to the low equipment accuracy and special hole position, a machine tool main shaft cannot get close to the hole, the cutter bar stretches too long, and the reamed hole machining accuracy is low are completely solved; the rough machining and the finish machining are integrated, and the production efficiency of hole machining is greatly increased.

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 positioning the partition on the abdominal ring rib of the MCL (horizontally split) casing 27. This pin hole 28 is at the bottom of the abdominal cavity of the casing 27. 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 processi...
