Device for converting two types of spindle tapered bores of machine tool

Abstract

A device for converting two types of spindle tapered bores of a machine tool, as a milling head, is arranged in the head part of the machine tool with a spindle tapered bore in the type of ISO60 and is further embedded with a guidance key of the primary spindle tapered bore. The device for converting two types of spindle tapered bores of a machine tool is characterized by a broach mechanism of an ISO50 tapered bore: a tapered handle is combined with an upper tapered handle up and down to form a conical shell; a pop-rivet is arranged on the dome of the first large outer diameter of a claw spindle which is arranged around the circle, the small inner diameter of a slide sleeve is arranged outside the small outer diameter of the pop-rivet, the small inner diameter at the upper section of a claw is blocked at the dome of the second large outer diameter of the claw spindle, a spring is arranged in an arc groove located on the outer wall of the claw, and a spring set is arranged along the outer edge and the lower part of the slide sleeve; a slide rod and a hook are arranged on the later side of the large-diameter platform of the tapered handle, and an elastically cylindrical pin is arranged inside a key which is combined with the transmission key of the spindle; the pop-rivet of an ISO50 cutter is clamped inside the tapered handle by the claw spindle to form a pop-rivet claw. The device enables one machine tool to use two types of cutters, realizes automatic dismounting and clamping and automatic cutter switching, and has an inner-cooling interface, high automation and high efficiency, thereby reducing the cost and better meeting the requirement of customers.

Description

technical field [0001] The invention relates to a taper hole conversion device for converting the spindle taper hole of a machine tool from ISO60 to ISO50 in mechanical manufacturing equipment. The ISO60 machine tool with a spindle taper hole can be equipped with ISO50 tools to meet different processing requirements. technical background [0002] According to the market demand of the machine tool processing industry, there are higher requirements for the processing capacity of CNC machine tools, mainly for high power, high torque, and high speed. During the processing of ISO50 type tools, some parts cannot meet the needs of users and need to use ISO60 tools; while the cost of ISO60 type machine tool tools is high, it is not suitable for mass purchase; and some processing can be replaced by ISO50 tools to save processing costs. However, there is no such dedicated device in current equipment. Contents of the invention [0003] The purpose of the invention is to provide a co...
