Embodiment

[0020] The specific implementation of the present invention will be further described below in conjunction with the schematic diagram of the control connection.

[0021] The following takes the feed axis X-axis as an example to describe in detail how the manual control device and the numerical control system can automatically switch between the main control and the redundant control. The detailed control connection diagram is as follows Figure 4 shown.

[0022] When the numerical control system breaks down or becomes paralyzed, it is only necessary to release the emergency stop switch SB0 on ​​the "manual control system", and the system effective switch SB1 is turned ON, and the normally open contacts of relays KA1 and KA2 are energized and closed, and the operation is completed. The control process of switching from the CNC system mode to the redundant manual control mode is realized, and the redundant manual control system takes effect, thereby realizing the fast and effect...

Abstract

The invention discloses a redundancy manual control system of a turning and milling composite machine tool. When a numerical control system is influenced by an external interference signal and can not work normally, a manual operation mode is provided to replace the system control mode, so that a numerical control machine tool can still meet the basic machine tool processing requirements. The redundancy manual control system adopts the technical scheme that the redundancy manual control system comprises a numerical control system control unit and a redundancy manual control system part; the redundancy manual control system part is connected with a servo motor through a feed shaft servo driver, is connected with a spindle motor through a spindle frequency converter, and integrates a control panel of the spindle frequency converter, impulse generators of various feed shafts, and control buttons. The redundancy manual control system is additionally arranged on the conventional control system, and the manual operation mode is provided to replace the system control mode, so that the numerical control machine tool still can meet the basic machine tool processing requirements in case of emergency when the numerical control system breaks down or is paralyzed.

Description

technical field [0001] The invention belongs to the technical field of numerical control machine tools in mechanical engineering, and in particular relates to a redundant manual control system of a turning-milling compound machine tool. Background technique [0002] When performing online maintenance on ships, special vehicles and other equipment, only one CNC turning and milling compound machine tool is needed to complete the processing of small parts such as turning, milling, grinding, drilling, reaming, boring, threading, etc., which can quickly complete easy The processing of damaged parts greatly saves the equipment space occupied by maintenance equipment. However, ships and special vehicles may encounter complex situations such as vibration, turbulence, magnetic explosion, pulse and other electromagnetic interference during actual field operations or combat preparations, which may cause failure or paralysis of the CNC system and cause the machine tool to fail to work. ...
