Description

Tube end position light curtain detects automatic positioning control system

Technical field the utility model belongs to automatic detection and control field, and the tube end position that is specifically related to the tubulation industry detects the Automatic Positioning Control technology.

Background technology is present, and the tube end position of domestic tubulation machining production line detects and adopts infrared sensor and ultrasonic sensor, and carries out Automatic Positioning Control with counter.The deficiency that this control mode exists is: 1. since the pipe end face of steel pipe not in one plane, deviation is also bigger sometimes.And just point that said method detects, some points with the steel pipe end face, witness mark as the steel pipe end face, if reserve the distance of pipe end and point of a knife according to normal method, when the detection reference point is the minimum point of pipe end, will cause process safety apart from deficiency, in process, cause tool damage.2. realize that the Automatic Positioning Control bearing accuracy is not high.

The summary of the invention the purpose of this utility model is to provide a kind of can improve device ', realize that quick pinpoint tube end position light curtain detects automatic positioning control system.

For achieving the above object, the technical scheme taked of the utility model is:

A kind of tube end position light curtain detects automatic positioning control system, it is characterized in that this system comprises:

The light curtain, it is fixed on the clamped beam front end face that is positioned on the big slide unit, is used to detect the pipe end face of steel pipe to be processed;

Variable-frequency motor is used to drive big slide unit and moves forward and backward along its track;

Scrambler, it is installed on the variable-frequency motor, and big slide unit speed, position that variable-frequency motor drives are detected;

Servo module is used to accept the pipe end face position signalling of the detected steel pipe to be processed of light curtain and the detected big slide unit speed of scrambler, position signalling, and the detection signal that receives is fed back to Programmable Logic Controller PLC;

Programmable Logic Controller PLC accepts and handles light curtain, the detected signal of scrambler by servo module, and sends operating instruction by servo module to variable-frequency motor, realizes that tube end position light curtain detects Automatic Positioning Control;

Touch-screen, PLC is electrically connected with Programmable Logic Controller, is used to set the travelling speed and the locator value from the light curtain to the final position of big slide unit.

The aforementioned tube end position light curtain that the utility model provides detects automatic positioning control system, owing to adopt the light curtain to detect the end face of pipe end, and use the servo position module to realize fast automatic location, thereby can avoid of the damage of pipe end projection to cutter, the safe distance of location back pipe end and point of a knife can be reduced to 1～2mm scope, improved device ', improved steel pipe end face machining precision simultaneously, reduced and processed the required time, improve working (machining) efficiency greatly, reduced raw-material loss.Efficiently solve present tubulation industry and add fast detecting and the accurate orientation problem of man-hour automatically pipe end.

Fig. 2 is the control principle synoptic diagram that tube end position light curtain detects automatic positioning control system

The utility model will be further described below in conjunction with accompanying drawing for embodiment.

As shown in Figure 1 and Figure 2, the pipe end face of steel pipe 1 to be processed adopts light curtain 2 to detect, and light curtain 2 is fixed on the front end face of clamped beam 4, and clamped beam 4 is installed on the big slide unit 3; Cutterhead and main spindle box 5 thereof also are installed on the big slide unit 3 in clamped beam 2 dead asterns, main spindle box 5 is driven by servomotor 6, servomotor 6 is electrically connected with servo module 9, accepts the signal controlling of Programmable Logic Controller PLC10 by servo module 9, and then realizes the position closed loop control of main spindle box 5; Big slide unit 3 is driven by variable-frequency motor 7, can move forward and backward along its track, the speed of big slide unit 3, position are detected by the scrambler of installing on the variable-frequency motor 78, scrambler 8 feeds back to Programmable Logic Controller PLC10 with detected signal by servo module 9, send operating instruction by servo module 9 to variable-frequency motor 7 by Programmable Logic Controller PLC10 again, thereby realize that tube end position light curtain detects Automatic Positioning Control.The touch-screen 11 that is electrically connected with Programmable Logic Controller PLC10 is used to set the travelling speed and the locator value from the light curtain to the final position of big slide unit.

The tube end position light curtain that the utility model provides detects automatic positioning control system, its control procedure is: steel pipe 1 1. to be processed puts in place, the processing beginning, send the F.F. operating instruction by Programmable Logic Controller PLC10 to servo module 9, servo module 9 control of conversion devices drive variable-frequency motor 7 rotations, variable-frequency motor 7 drives big slide unit 3 by gear train and walks forward, drives light curtain 2 simultaneously and moves forward; 2. when light curtain 2 detects the pipe end face of steel pipe 1, send the location commencing signal, realize positioning control from light curtain 2 to the final position to servo module 9; It is to feed back to servo module 9 by scrambler 8 to control that the physical location of 3. big slide unit 3 detects; The travelling speed of 4. big slide unit 3 and the locator value from light curtain 2 to the final position can be set by touch-screen 11, can set according to the technological parameter of processing steel pipe simultaneously.
