Embodiment 1

[0033]Referring to Fig. 3, the present invention, as a digital control line contact curved surface processing equipment, includes a digital control system, a power drive source, and a coordinate feed system with numerically controlled multi-axis motion. The key point is that it must also have a four-axis contact The curved surface processing device, the four-axis contact curved surface processing device is mainly composed of five parts: a rotary assembly, a translation assembly, a swing assembly, a telescopic assembly and a cutting assembly. The rotary body 4 and the upper bearing 5 are composed of two bearings 3 and 5 fixed on the support frame member 2, the rotary body 4 is statically connected with the upper bearing inner ring 7 and the lower bearing inner ring 8 respectively, and the rotary motor 6 is installed on the support frame On part 2, the shaft rotation of motor 6 drives the rotary body 4 and its extension 19 to form the feed axis of rotary motion, that is, the C ax...

Embodiment 2

[0037] The overall device is the same as in Embodiment 1, except that the rotating body 4 and its extension 19 are connectors, which are manufactured in parts and then installed. The support frame member 2 is also a combined member, consisting of upper and lower members and a cover, manufactured in parts and then installed, which is easy to process, easy to install, low in cost, and also conducive to improvement.

Embodiment 3

[0039] The overall device is the same as that of Embodiment 1, except that the lower bearing 3 and the upper bearing 5 in the rotary assembly are replaced by one bearing, which can simplify the structure.

Abstract

The invention relates to a digital-control line-contact surface processing method and the equipment, belonging to the mechanical processing field. The core is four-axis line-contact surface processing device comprising rotating module, translating module, swinging module, expanding module and cutting module. The cutting module is set on the expanding module and it following said four modules moves in space. In the invention NC multi-axis moving coordinate feeding system with four-axis line-contact surface processing device is used; according to the processing demand, multiple multi-axis NC surface processing machine tool can be constituted. The side blade of cutting tool is controlled to machine in tangency with straight generatrix of machining surface always to realize the processing method that a code is used to machine a special surface or any space plane. It is provided with no theoretical profile error, high efficiency and high accuracy. The least linkage axis number and the least NC machining codes are used to realize surface processing. It can be applied in NC milling finishing machining, finish machining, NC turning-milling machining, NC electrochemical machine and NC EDM so on.

Description

technical field [0001] The invention relates to the technical field of machining, and belongs to equipment and methods for numerically controlled machining. The method and equipment for machining curved surfaces with digital control line contact are the method and equipment for machining curved surfaces of workpieces by adopting the line contact machining method. Background technique [0002] Various curved surface numerical control processing such as milling and grinding in the known technology at present all use the method of approximation or fitting to convert the curved surface into a small plane sheet or curved surface sheet, and then adopt the traditional point-line processing method, This requires a large amount of tool position data, and multi-axis linkage processing with 3-axis, 4-axis or 5-axis (and above) machine tools. In this processing method, the pursuit of processing efficiency and error control are a pair of contradictions that are difficult to reconcile. ...
