Embodiment Construction

[0028] Such as figure 1 As shown, according to the hobbing principle of the face gear, the multi-axis linkage machine tool must be able to realize the four movements of the main movement, the sub-tooth movement, the vertical feed movement and the horizontal feed movement of the face gear CNC hobbing. At the same time, due to the existence of the helix angle of the hob, the axis of the hob must rotate around the section of the face gear by an angle of the helix angle, such as figure 2 As shown, but due to the limitation of the machine tool structure, the spindle tool cannot complete the rotation of a helix angle, which brings inconvenience to the processing. To solve this problem, the tool is not moved, and the workpiece is offset by a distance relative to the original position. Equivalently complete the rotation of the helix angle of the face gear hob, such as image 3 shown. no w Represents the speed of the hob, n 2 Represents the rotational speed of the workpiece, f 1 ...

Abstract

The invention relates to a numerical control gear hobbing processing control device and method for a face gear, wherein the numerical control gear hobbing processing control device for a face gear comprises the control device, a gear hobbing machine, a numerical control rotary table, a transmission mechanism and a face gear workpiece; the control device comprises an industrial control computer, an SERCOS (Serial Real-Time Communication System) card, a control panel, a SERCOS optical fiber, a KE (Kontrolle Erganzen) rectification power supply module, a KW (Kontrolle Wechseirichter) main shaft control module, a KW feed control module and a PLC(Programmable Logic Controller)-IO (Input Output) module; the SERCOS card is installed on the industrial control computer through an ISA (Industrial Standard Architecture) socket, and the control panel is connected with the SERCOS card through a control wire so as to send out various kinds of control instructions; the SERCOS card is connected with the KE rectification power supply module, the KW main shaft control module and the KW feed control module through the SERCOS optical fiber; and the KW main shaft control module is connected with a main shaft motor, and the KW feed control module is connected with each feed motor through a control wire. The invention can realize the highly-efficient precise processing of the face gear.

Description

technical field [0001] The invention relates to a novel gear-face gear numerical control hobbing processing control device and a processing control method, which are suitable for the numerical control hobbing processing of face gears with any shaft intersection angle. Background technique [0002] Because face gears can be processed by gear shaping, hobbing and grinding, and the processing technology of face gears abroad is strictly kept secret, so the processing technology has not been mastered in China. The advantages and wide application of face gear transmission have been recognized in China However, the in-depth research on face gear transmission has been seriously limited due to the lack of domestic face gear processing capabilities, which has hindered the progress of face gear transmission experiments and applications. There is no systematic research on gear hobbing. The gear shaping processing method of facing gears in China is relatively in-depth. Both China Southe...
