[Prior Art] [〇〇〇2] With the development of technology, the traditional manual manufacturing manufacturing industry has gradually been replaced by CNC machine tools. The high degree of automation of CNC machine tools can reduce the labor intensity of workers, which not only improves production efficiency, but also can process more complicated songs.

Therefore, the position of CNC machine tools in the machinery manufacturing industry is becoming more and more important, and its stomach use is becoming more and more common. _3] & machine tool plus ji parts _ general principles are as follows: first recorded according to part drawings and work

The program of the art program is written in the prescribed code and program format, and then the control person on the CNC machine tool reads the person. After processing it, the clothing system issues a nickname (5) service system to drive the moving parts of the machine tool according to the signal, thereby Move the machine spindle to crown the part. In the process of CNC machine tool machining, the pre-twisted program medium tool travels according to the predetermined trajectory. However, with the wear of the tool, the replacement of the tool and the deformation caused by the heating of the workpiece, the H is often caused by the deviation. It may cause the tool to collide with the machine bed or fixture, which may cause damage to the tool or the machine. [_The method of solving this problem is to ensure the accuracy of the processed materials by testing the processing program many times before processing. However, the singularity is free from the processing process, resulting in the deviation of the system, resulting in the tool and the machine bed. Collision, damage to tools and machine tools. _5] (4) This is necessary to provide a reliable on-line detection of CNC machine tool collision detection system. 0993193294-0

093141686 her number is fine 1 ^ 3 10 M 1330303 [0006] [0007] Boxing [0008] [0009] [0010] 093141686 099, June 1st [Invention] The object of the present invention is to provide a reliable online detection CNC machine tool collision automatic detection system. The automatic collision detection system for numerical control machine tools of the invention comprises: an input device for reading into a machining program; a storage device for storing obstacle data; and a ship for comparing obstacles and tool movements (4) a device issued by (4) a moving component from the pure signal of the ship line; wherein the control device compares the data of the process of searching for % into the storage device, and if there is a set of data, the control device stops processing the signal and is sent by the servo system. For the sports department. ° 1 thousand ' If there is no intersection, the control device will send the processing path code to the moving parts by means of the servos, and the JL will be added to the moving parts, and the invention will be compared with the conventional technology. t Machine collision automatic detection system can perform on-line detection on the online Ρ%% when the work is officially carried out, avoiding collision between the tool and the obstacle in the working machine, which can effectively prevent the CNC tool from being damaged and operate safely. When the CNC automatic collision detection system detects a collision, ^ can automatically stop at the position, and the user finds a dangerous position, and then Change processing program. [Embodiment] The numerical control machine tool colliding automatic blessing and smashing of the present invention comprises: a program carrier 1 (), an input device 20, a storage device 30, a body 10 control device 40, and a servo system 5n month moving component 60. . In the ^0 and please refer to the first picture, the program carrier 1〇 is used to record the processing program, add more. According to the pattern of the parts and the work of the large & red beta case, the code is written in accordance with the prescribed code and the program is written. The prepared engineering leather & ° sequence is recorded on the program carrier 10, and the process library form number is Α0101. Page 4 / a total of 10 Mad juice page 1330303 099 June 01 nuclear replacement page carrier ίο can be perforated paper tape, floppy disk, and so on. [0011] The input device 20 can read in a processing program in the form of an optoelectronic reader, a keyboard or a computer interface. The machining program can be entered in one piece or all.

[0012] The storage device 30 is configured to store obstacle position data that the tool may encounter, and each obstacle position data is represented by an equation, thereby forming a database. Taking the embodiment as an example, setting a coordinate origin and a clamp position. The range is defined as Xi<x<x2,y/yfyg,Zi<z<z2, where 乂丨, x2, yi, y2, verbose, z2 respectively represent the boundary of the fixture position, χ, y, z are within this range Collision range. Other objects that may collide with the tool can be represented by equations. The above data is pre-stored in the database for later use.

[0013] The control device 40 reads the processing program on the program carrier 10 and the data on the storage device 30. The control device 40 includes a comparison system that performs the tool path in the machining program with the position of any obstacle. In comparison, if there is an intersection point, that is, the tool position point is located, yi&lt;y<y2, Ζι<Ζ<Ζ2, indicating that the tool is within the collision danger range, the comparison system will send a warning signal to the control device 40 and stop. Workpiece movement. If the intersection point is not found, ie, the tool position point is not in the range of X &lt;x&lt;x, y &lt;y<y,z &lt;z&lt;z, the control device 40 will press 1 L· 1 c* 1 L· The machining program continues to be processed. [0014] The servo system 50 amplifies the signal of the control unit 40 and transmits the signal to the servo motor, which drives the moving part 60 and controls the necessary auxiliary operations. 093141686 Form No. A0101 Page 5 / Total 10 Page 0993193294-0 [0015] 1330303 On June 1, 099, the moving part 60 includes a tool and a main moving part 60 that drives the movement of the workpiece, and is connected to the servo system 50 to drive the tool and the workpiece. Exercise, processing the required workpiece.

[〇〇16] When working, the processing program on the program carrier 10 is read by the wheeling device 20, and then the technical difficulty is transmitted. The reading is added with the X material, and at the same time, the data of the storage device 3G is read by the person. The comparison system of the control device 4Q compares the two. If the solution has an intersection, the comparison system will send a signal to the control device 40 and stop the motion, and the control device 4 sends a signal to the servo system 5G to stop. Movement of the moving part 6(). If there is no intersection, the control device 4 will continue to follow the instructions of the machining program and process the obtained data, and then pass the command to the vocabulary system 50 | The machining operation is performed by the motor to drive the moving member 60. [0017]

It can be understood that the 'machining program can also be realized by the CAD system, which can simulate the shape of the part and automatically generate a data file, which is read by the control device 4' and then compared with the data of the obstacle by the control device. . [0018] The obstacle data of the storage device 3G can also be written together with the tool path when the machining program is programmed.
