Automatic detection device and method for guide sleeve

Abstract

The invention relates to automatic detection of a guide sleeve of a numerical control deep hole drilling machine, in particular to an automatic detection device and method for a guide sleeve. The automatic detection device for the guide sleeve comprises a guide sleeve body, springs and a proximity switch, wherein the outer surface of the guide sleeve body is provided with fixing brackets, sinker bars can penetrate through the centers of the fixing brackets, the springs are installed at the positions, between the fixing brackets and metal sheets, of the sinker bars, the proximity switch corresponds to one fixing bracket and is located on the same horizontal plane with the fixing bracket, and the proximity switch is connected to a PLC. The automatic detection method for the guide sleeve includes the following steps that when the guide sleeve body moves to the surface of a tube sheet, a detection ring approaches the guide sleeve body; the corresponding sinker bar connected with the detection ring approaches the proximity switch; the metal sheet at one end of the corresponding sinker bar makes contact with the proximity switch to trigger the proximity switch; the proximity switch feedsa signal back to the PLC; and the PLC detects the status of the guide sleeve body in real time. Automatic detection of the return action of the guide sleeve can be achieved, and product quality problems and equipment accidents caused by the action failure of the guide sleeve are avoided.

Description

technical field [0001] The invention relates to automatic detection of a guide sleeve of a numerically controlled deep hole drilling machine, in particular to an automatic detection device and method for the guide sleeve. Background technique [0002] At present, there is no detection and feedback device for the guide sleeve of the CNC deep hole drilling machine at home and abroad, that is, the existing guide sleeve of the CNC deep hole drilling machine used for tube sheet drilling cannot realize the detection feedback, that is, it is impossible to detect whether the actual action of the feedback guide sleeve is in place. The failure of the sleeve often causes product processing quality accidents and equipment precision accidents. During the production process, the guide sleeve telescopic failure often occurs. When the guide sleeve should be retracted after drilling the previous hole, the actual failure of the solenoid valve or the actuator of the hydraulic system does not r...
