A Floating Boring Tool Arbor for Deep Holes

Abstract

The invention discloses a floating boring tool bar for deep holes, which includes a tool seat, six discharge grooves are opened on the outer wall of the tool seat along the circumferential surface, and scrapers are slidingly embedded in the inner walls of the six discharge grooves. The inner side of the seat is provided with six reset chutes, and the tops of the six reset chutes are connected to the bottom axis of the discharge groove, and the centers of both sides of the inner walls of the six reset chutes are fixedly provided with limiting rods to limit The outer walls of the rods are all slidingly sleeved with return springs. By cleaning the nozzle, scraper, return spring and discharge groove, rapid discharge of waste water and debris can be achieved to avoid clogging of deep holes with waste water and debris, resulting in substandard precision of workpieces and even jamming of boring tools , through the anti-friction sleeve, cooling nozzle, and installation rod, the temperature of the boring tool can be cooled from time to time, avoiding the problem of boring tool breaking due to excessive tool feed, and further improving the working stability of the boring tool.

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
