Automatic loading gear alignment method and device for articulated robot-based gear cutting machine

Abstract

The invention relates to an automatic loading gear alignment method and a device for an articulated robot-based gear cutting machine. The method comprises the following steps: clamping a gear to be cut by a loader to move towards a cutter, leading the gear to be cut to be approximately parallel to the axis of the cutter after entering a gear alignment area, wherein the gear to be cut can rotate along the axis of the gear in the loader, the loader can swing back and forth relative to the cutter so as to close to the cutter until the gear to be cut enters a cutting position; and the device comprise an articulated robot and clamp claws arranged thereon, each clamp claw comprises a clamp claw base and two-finger translation manipulators, the two-finger translation manipulators comprise a cylinder and a pair of claw fingers, and the two claw fingers are provided with arc-shaped clamping surfaces. The method can fast lead the gear to be cut to be aligned and sent at the position to be cut, and the whole alignment process is automatically conducted by the loader, so that the operation is simple, the alignment is accurate and the production efficiency is high; and the device can lead the gear to be cut to close to the cutter by a fold line movement track, and complete the alignment operation of the gear during closing.

Description

Technical field [0001] The invention relates to a gear processing method and device, in particular to a method and device for automatic feeding and tooth alignment of a gear processing machine tool based on a joint robot. Background technique [0002] For the finishing of gear shapes such as gear shaving, gear honing, gear extruding and gear grinding, the earlier method of feeding is carried out manually, and the tooth alignment work is also done manually; currently only part of the new The machine tool realizes automatic loading through a linear mechanism such as a Cartesian coordinate robot, but the linear coordinate robot only completes the loading and unloading of the workpiece to the tray, and the tooth alignment work is completed by the machine tool; the machine tool completes the tooth alignment work, and the machine tool spindle is a servo spindle. Higher requirements for machine tools increase the cost of the machine tool. In addition, the system is not flexible enough,...

Problems solved by technology

This invention can realize automatic gear alignment, reduce the labor intensity of workers and improve production efficiency, and creates conditions for fully automatic processing of gears; however, the device has a complex structure and high cost, especially the existence of multiple detection links, making control difficult Higher, it is difficult to get the gear to be processed into the position to be processed accurately in a short time, so it is difficult to obtain a relatively fast alignment effect; especially for mass production and manufacturing, it is difficult to greatly improve the production efficiency compared with the manual alignment method
