Angle milling head with double-lead worm and worm gear transmission anti-backlash device

Abstract

The invention discloses an angle milling head having a dual-lead worm and gear transmission clearance removing device in order to improve the processing precision of the angle milling head. The angle milling head comprises an angle milling head base and a milling head body, wherein the milling head body is mounted on the angle milling head base through a guide drive mechanism and can perform bidirectional swing around a reference axis under the holding of the guide drive mechanism; the dual-lead worm and gear transmission clearance removing device is adopted as the guide drive mechanism; a dual-lead worm is located in a casing through a front end rotation support assembly and a rear end rotation support assembly; the front end rotation support assembly comprises a front end sleeve part; an inner hole wall of the front end sleeve part forms a front end guide hole and a front end thread hole from inside to outside; a front end bearing closely matched with the front end of the dual-lead worm is mounted in the front end guide hole and is in axial sliding fit with the front end guide hole; and the end face of an outer circle on the external side of the front end bearing is axially pressed from outside to inside by a front end adjusting screw adaptively connected with the front end thread hole.

Description

technical field [0001] The invention relates to a multi-axis numerical control processing equipment, in particular to a three-dimensional soft model cutting forming machine for cutting soft materials such as oil sludge, foam, wood or light resin and forming them into a three-dimensional solid model. In addition, the invention also relates to a three-dimensional soft model cutting and forming method. Background technique [0002] In the field of industrial design such as automobile modeling, it is often necessary to use soft materials such as oil sludge to make 3D solid models for simulation. One of the more advanced methods is to use three-dimensional modeling software to design in the computer, and then use multi-axis CNC cutting equipment to process soft materials according to the designed shape. However, there is no special equipment for cutting and forming a three-dimensional soft model, which can quickly, smoothly and accurately process complex shapes, and at the same ...
