Problems solved by technology

[0002] At present, manufacturers generally use the following three methods when processing large tapered holes: one is to use a large tapered reamer to ream the tapered hole. This method takes a long time to process the tapered hole, and the production efficiency is low. It will affect the processing accuracy of the tapered hole, and the reamer is disposable, and the price is relatively expensive; the second is to use the flat rotary disc boring method, which is limited by the expensive price of the flat rotary disc; the third is to use the arc cutter The processing method o

Abstract

The invention discloses a boring and countersunk device of a digit control machine tool, and a boring and countersunk method, which comprises a taper-shank arbor, an internal gear, a satellite gear, a main gear, and a tool bar, and is characterized in that the device also comprises a main bevel gear, an auxiliary bevel gear, a speed reducer and a base; a boring cutter radial driving mechanism is arranged in the base; the automatic boring of a taper hole is realized by inputting the thread pitch value of a digital thread instruction; the boring and countersunk device of the digit control machine tool, and the boring and countersunk method have the advantages of simple structure, high production efficiency, shortened time for processing the taper hole, guaranteed processing precision and surface roughness of the taper hole, and lowered production cost.

Description

technical field [0001] The invention relates to a device for boring taper holes of a numerically controlled machine tool, which is used for boring taper holes of a numerically controlled boring and milling machine. Background technique [0002] At present, manufacturers generally use the following three methods when processing large tapered holes: one is to use a large tapered reamer to ream the tapered hole. This method takes a long time to process the tapered hole, and the production efficiency is low. It will affect the processing accuracy of the tapered hole, and the reamer is disposable, and the price is relatively expensive; the second is to use the flat rotary disc boring method, which is limited by the expensive price of the flat rotary disc; the third is to use the arc cutter The processing method of helical differential compensation and line approximation, because the surface of the taper hole processed by this processing method is formed by line approximation, the...
