Floating boring cutter bar for deep holes

Abstract

The invention discloses a floating boring cutter bar for deep holes. The floating boring cutter bar for the deep holes comprises a cutter holder; six discharge grooves are formed in the outer wall ofthe cutter holder along the circumferential surface; scraping plates are slidably embedded in the inner walls of the six discharge grooves; six reset sliding grooves are formed in the inner side of the cutter holder; the top ends of the six reset sliding grooves are arranged at the bottom end axes of the discharge grooves in a communicating manner; limiting rods are fixedly arranged at the centersof the two sides of the inner walls of the six reset sliding grooves; and return springs sleeve the outer walls of the limiting rods in a sliding manner. According to the floating boring cutter bar for the deep holes, through cleaning sprayers, the scraping plates, the return springs and the discharge grooves, waste water and debris can be discharged rapidly, and the problems that the precision of a machined part does not reach the standard and even a boring cutter is blocked caused by the fact that the deep holes are blocked by the waste water and the debris are avoided; and through an anti-friction sleeve, cooling nozzles and a mounting rod, the boring cutter can be cooled in time, the problem that the boring cutter is broken to cause jamming due to too large feeding amount of the boring cutter is avoided, and the working stability of the boring cutter is further improved.

Description

technical field [0001] The invention belongs to the technical field of boring cutters, in particular to a floating boring cutter holder for deep holes. Background technique [0002] Boring tool is a kind of boring tool, generally with round handle, and there are also square tool bars for larger workpieces. The most commonly used occasions are boring tool inner hole processing, reaming, profiling, etc., with one or two cutting parts , A tool specially used for roughing, semi-finishing or finishing the existing holes, the boring tool can be used on a boring machine, lathe or milling machine. [0003] At present, most of the boring tools are fixed directly by the tool bar bolts. In the actual use process, due to the accumulation of a large amount of coolant and debris inside the deep hole, it is easy to cause the debris to rub against the workpiece, resulting in The precision of the deep hole is not up to standard, and even damage occurs. Secondly, in the process of processing...

Problems solved by technology

[0003] At present, most of the boring tools are fixed directly by the tool bar bolts. In the actual use process, due to the accumulation of a large amount of coolant and debris inside the deep hole, it is easy to cause the debris to rub against the workpiece, resulting in The precision of the deep hole is not up to standard, and even damage occurs. Secondly, in the process of processing, different materials need to use different feed amounts. Once the feed amount is too large, it is very likely that the boring tool will be stuck and stuck due to overheating. The problem of breaking, which in turn causes the problem of stuffy turning on the lathe, which is not conducive to stable processing
