CNC machine tool, and online testing fool-proof method and system for air cylinder clamp thereof

Abstract

The invention discloses an online testing fool-proof method for an air cylinder clamp of a CNC machine tool. The online testing fool-proof method for the air cylinder clamp of the CNC machine tool includes the steps that a probe is perpendicularly arranged at an initial position above the surface of the air cylinder clamp at the distance of a preset height; the probe is moved downwards by a presetdistance, whether the probe touches a press block located on the surface of the air cylinder clamp in the moving process or not is detected, and if yes, a user is warned according to a preset warningmode; and the length of the preset distance is smaller than the difference between the preset height and the height of the surface of the press block when an air cylinder is tensioned. Within the preset distance that the probe moves downwards, if the air cylinder is not in a tensioned state, the air cylinder will eject the press block by a certain distance, the press block is then located withinthe length of the preset distance, and therefore the press block is touched by the probe when the probe moves downwards. Therefore, the online testing fool-proof method for the air cylinder clamp, thework state of the air cylinder clamp can be accurately judged in real time, the user is reminded to carry out corresponding operations, and accidents are prevented.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tools and automatic control, in particular to an online detection and anti-fooling method for cylinder fixtures of CNC machine tools. The invention also relates to an online detection and anti-fooling system of a cylinder fixture of a CNC machine tool and a CNC machine tool. Background technique [0002] With the development of China's machinery industry, more and more machinery and equipment have been widely used. [0003] In the machining and manufacturing industry, there are more and more processing techniques for workpieces, such as turning, milling, planing, grinding, etc., and the corresponding processing equipment is lathes, milling machines, planers, grinders, etc. On the lathe, it is generally used to process rotary parts, etc. Since the machine tool runs at a high speed, it can reach tens of thousands of revolutions per minute. Therefore, before processing the workpiec...

Problems solved by technology

[0005] However, in labor-intensive industries such as machining, technicians often need to supervise and operate dozens of machine tools at the same time. For CNC machine tools, operations such as opening or closing air valves, etc., repeat monotonous actions for such a long time. Forgetting or ignoring the operation of opening the air valve will cause the fixture and workpiece to be damaged by the tool, and even endanger personal safety.
