Abstract

The present invention provides a cam machine capable of machining cam hyperbolic grooves of swing arm type high-speed small six-shuttle circular looms with high precision. The present invention has the technical characteristic that the left-and-right swing of a power milling head is driven by the revolution of a pair of three-convex three-concave symmetrical master form cam curve planes so as to machine a curve groove with high precision. The included angles between the upper plane and the horizon, and between the lower plane and the horizon are changed every time the machined cam revolves by 1DEG. A mechanism driving the power milling head to swing eliminates gaps among all components in sliding fits by using a tight expansion taper sleeve device, so that the power milling head can not vibrate when carrying out the large cutter quantity bite of the curve groove with the cross section of 20*20MM. The actions of the cutter feeding, the cutter retreat and the cutter change of the milling head are realized by two simple-structure tool carriages vertically arranged and two simple-structure tool carriages horizontally arranged. The power milling head is simple in structure; the top end of the power milling head is provided with a 1.5KW six-pole motor, and the revolution speed of the milling cutter is reduced to 288 revolutions per minute through the speed reduction of a pair of helical gears. A power transmission mechanism only has a main shaft; a 1.1KW speed regulating motor is used for driving all components correspondingly revolving and swinging on the whole cam machine so as to meet the requirement of synchronous operation; and all the transmission is formed by the gear engagement so as to eliminate errors at the time of synchronous operation. The cam machine only has few main components requiring high precision in machining and installation, and the total cost of the cam machine is less than ten thousand RMB.
