Digital servo tool turret controller

Abstract

The invention provides a digital servo tool turret controller. A shell is provided with a numerical control system signal input end and a servo control signal output end; a digital servo tool turret control circuit is arranged in the shell and provided with a numerical control system signal communication circuit, a singlechip processing circuit and a servo control signal communication circuit; and a digital servo tool turret control program is arranged in a singlechip. During use, the controller receives a numerical control system signal command of a selected tool number sent by a numerical control system; the command enters a singlechip circuit through the CNC system signal input end and is operated by the singlechip; a servo control signal is output to drive a servo motor to rotate positively or reversely and perform a tool selection command; when a selected tool position is reached, a stop signal is sent, tool selection is ended and tool turret position arrival response signal is sent; and the numerical control system receives the tool turret position arrival response signal so as to monitor the correctness of work. The tool selection command is sent from a singlechip circuit processing system, so the servo motor can be driven to rapidly and correctly select the tool.

Description

technical field [0001] The invention relates to a turret controller of a numerically controlled lathe, in particular to a digital servo turret controller of a numerically controlled lathe. Background technique [0002] CNC lathe turret is the tool changing device of CNC lathe. The cutterhead shaft of the turret has an axial drive device and a circumferential drive device. When the turret is changing tools, the axial drive device first pushes the cutterhead shaft to move axially, so that the movable end toothed disc is out of mesh with the fixed end toothed disc. , and then the circumferential drive device drives the movable end toothed disc to rotate, so that the new knife used in the next processing step on the movable end toothed disc can be transferred to the working position. The axial drive device of the turret shaft of the CNC lathe is a hydraulic cylinder, so the turret is called a hydraulic turret, the circumferential drive device of the turret shaft of the hydrauli...

AI Technical Summary

Problems solved by technology

The circumferential driving device of the above-mentioned hydraulic turret is a hydraulic motor, and the driving speed of the hydraulic motor is not very fast, and it is not very accurate to transfer the new knife used in the next processing step to the working position, so the production preparation time is longer and the labor productivity is lower. Not very high; for accurate positioning, there must be a matching movable convex and concave locking device between the tower body of the turret and the movable end tooth plate, and the structure is more complicated

The ideal circumferential driving device is a servo motor, which has fast indexing and high positioning accuracy. The servo motor of the circumferential driving device must have a digital servo turret controller during work. In the prior art, there is no digital servo with better performance.
