Claims

[Scope of utility model registration request]

(1) A tool holding shaft including a spindle mounting part and a tool holding part with an oil passage, and a tool holding shaft that is attached to the outer circumference of the tool holding shaft so as to be relatively rotatable and communicates with the oil passage of the tool holding part. A support block equipped with an oil passage with an oil inlet on the extension side of the spindle mounting part of the holding shaft, and a support block that is fixed to the support block and extends parallel to the tool holding shaft, and is attached to the spindle mounting part of the tool holding shaft. When attached to the spindle, the pin has a tip that can be loosely inserted into the oil outlet hole of the oil supply block attached to the frame adjacent to the spindle, and is attached to the outer periphery of the pin so that it can move within a predetermined range along the pin. and a cylindrical shape that forms a first oil receiving passage between the tip side corresponding part of the pin and the outer circumferential part of the pin, which is always biased via a spring so that the tip side of the pin takes the maximum movement position. It has a second oil receiving passage adjacent to the cylindrical part that communicates with the first oil receiving passage and the oil inlet of the oil passage of the support block, and has a second oil receiving passage that communicates with the oil inlet of the oil passage of the support block, and a second oil receiving passage that communicates with the oil inlet of the oil passage of the support block. an oil receiving block having a tip surface that can be sealingly engaged with an end surface around the outer end of the oil outlet hole of the oil supply block when the block is loosely inserted into the oil outlet hole;
When the oil receiving block, which is provided on the side of the oil receiving block, assumes the maximum movement position on the tip end side of the pin, it engages with a part of the tool holding shaft, and the relative relationship between the tool holding shaft and the case block. A tool holder with an oil hole that consists of a stopper that prevents excessive rotation.

(2) The oil hole according to claim (1) of the utility model registration, wherein at least two center-opposed circumferential walls of the tip end of the pin are configured to be able to contact and engage with the oil outlet hole wall of the oil supply block. Tool holder with.
