External-cooling-into-internal-cooling tool handle and external-cooling-into-internal-cooling tool handle assembly

Abstract

The invention relates to an external-cooling-into-internal-cooling tool handle and an external-cooling-into-internal-cooling tool handle assembly. The external-cooling-into-internal-cooling tool handle comprises a tool handle body, a positioning ring, a bearing base, bearings, a positioning pillar, an elastic piece and a tool changing block. When the tool handle body needs to be assembled or takendown, a mechanical arm grabs the tool handle body to make the tool handle body stretch into or separated from a main shaft, then the tool handle body moves downwards or acts on the positioning pillardownwards, then a first clamping part and a second clamping part are loosened or clamped, and then the tool handle body freely rotates or gets limited. Internal cooling lubricating is achieved through an internal cooling tool; meanwhile, positioning is achieved through the first clamping part on the positioning ring and the second clamping part on the positioning pillar, the purpose of quickly changing a tool handle is achieved, manual adjustment of the position or jetting angle of a nozzle is avoided, the efficiency is improved, the labor cost is lowered, and quality stability of the productis guaranteed.

Description

technical field [0001] The invention relates to the technical field of cutting processing, in particular to an externally cooled and internally cooled tool holder and an externally cooled and internally cooled tool holder. Background technique [0002] At present, the existing minimum quantity lubrication system generally uses external nozzles for oil mist spray lubrication in machine tool processing, and the operator manually adjusts the angle and distance between single or multiple nozzles, workpieces and tools to achieve the required lubrication. cooling effect. However, this method of lubricating with an external nozzle is only suitable for conventional milling, shallow depth drilling, etc., and for some deep hole processing, or deep groove milling processing, this lubrication method is difficult to lubricate the tool tip, thus The life of the tool is greatly reduced, and the processing quality of the workpiece will also be greatly affected. [0003] In addition, durin...

Problems solved by technology

The result of this is low efficiency and increased labor costs. In addition, manual adjustment is difficult to ensure consistency, and there is uncertainty. As a result, the cooling effect of each handle may be different, and the stability of product quality cannot be guaranteed.
