Abstract
The invention discloses a pipe-cutting feeding control method of a pipe cutting machine and belongs to the technical field of bearing ring machining. An existing bearing ring pipe cutting method has the defects of being low in efficiency, high in rejection rate and not capable of ensuring machining precision. The pipe-cutting feeding control method of the pipe cutting machine utilizes a mechanical feeding mechanism to push a hollow tube, and a servo system controls a servo motor to drive a carriage to drive a cutter to move and feed together. A programmable logic controller (PLC) only sends a start signal to the servo system, and the servo system finishes X-axis feed drive, memories the current position of the servo motor when a positioning sensor touches the end portion of the hollow tube and calculates a servo target position with a digital signal processor (DSP) and the like. The X-direction servo motor which runs continuously is controlled to drive the carriage to feed in the X-axial direction get the target position according to the calculated servo target position, and then feeding on the Y-axial direction is controlled to finish cutting. When cutting is finished, the Y direction is reset, and the PLC sends the start signal to the servo system so that a next cutting process starts. Positioning precision and anti-interference capacity are improved.
Description
Technical field
The invention belongs to bearing ring processing technique field, especially relevant with a kind of pipe cutter pipe cutting feed control method cut for bearing ring.
Background technology
Bearing ring pipe cutter is the processing equipment of an initial procedure in bearing machining field, it is mainly the needs of hollow pipe according to bearing ring width, be cut into the lasso blank of isometric size, pipe cutter on existing market adopts mechanical feed mechanism to push hollow pipe in pipe cutter X-axis (hollow shaft to), on front side of X-direction hollow pipe, position-limit mechanism restriction is set according to ring width and send length of tube, planker moves and controls cutter in the cutting of pipe cutter Y-axis (vertical direction of hollow pipe axis) upper feeding, often send a defective material to cut a lasso.Such pipe cutting method pipe cutting inefficiency, and feed section is often because send not in place, causes that machinery location is inaccurate and lasso that is cutting is defective, and percent defective is high.And the pipe cutter employing of servo-drive feeding type arranges inductor induction hollow pipe position on front side of X-direction hollow pipe, PLC sends pulse signal and controls servo-drive planker band with cutter after pipe cutter X-direction upper feeding ring width, stop sending X-axis feeding pulse signal according to hollow pipe position feed back signal, servo-drive planker band cuts in pipe cutter Y direction upper feeding with cutter, because the external interrupt response time uniformity of common PLC is poor, easily cause inductor and hollow pipe contact wear, also easy stroke feeding cumulative errors, reduce machining accuracy, and servo execution architecture is without feedback, machining accuracy is difficult to ensure.
Summary of the invention
Object of the present invention will solve under existing bearing ring pipe cutting method efficiency exactly, percent defective is high, the unwarrantable defect of machining accuracy, provides a kind of and can enhance productivity and the pipe cutter pipe cutting feed control method of machining accuracy.
For this reason, the present invention is by the following technical solutions: a kind of pipe cutter pipe cutting feed control method, mechanical feed mechanism is adopted to push hollow pipe in pipe cutter X-direction, servo system control X move forward in pipe cutter X-direction to the connected X of driven by servomotor to planker carry its tools to, servo system control Y-direction driven by servomotor connected Y-direction planker carry its tools move forward in pipe cutter Y direction to, planker location in the X-axis direction uses telescopic alignment sensor sensed position, it is characterized in that: during planker feed motion, first send enabling signal by the PLC of control system to servo-drive system, the X of servo-drive system starts to drive X to planker feed motion in the X-axis direction to servomotor, when alignment sensor touches hollow tube end, servo-drive system memory X is to the current location of servomotor, X still remains in operation to servomotor, while memory current location, the dsp processor of servo-drive system inside calculates servo target location, servo-drive system according to the servo target location control X calculated to driven by servomotor X to planker in the X-axis direction feeding move, after arriving target location, servo system control Y-direction driven by servomotor Y-direction planker in the Y-axis direction feeding moves the distance of setting, cutter cutting hollow pipe, hollow pipe thrown off by alignment sensor, cut rear base plate Y-direction under Y-direction driven by servomotor to reset, PLC sends enabling signal to servo-drive system, start next cutting process.
Use the present invention can reach following beneficial effect: the present invention adopts PLC only to provide servo enabling signal, the pipe cutting feed control method that other are all completed by servo-drive system, improve positioning precision and the antijamming capability of pipe cutting control.
Accompanying drawing explanation
Fig. 1 is principle schematic of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
As shown in Figure 1, the inventive method, hollow pipe 7 rotates by pipe cutter main shaft band is same, and adopt mechanical feed mechanism 8 in pipe cutter X-direction, push hollow pipe 7 to move, servo system control X to servomotor 1 drive X to planker 3 move forward in pipe cutter X-direction to, Y-direction servomotor 4 drive Y-direction planker 5 carry its tools 6 move forward in pipe cutter Y direction to, X uses telescopic alignment sensor 2 sensed position to planker location in the X-axis direction, during planker feed motion, first send enabling signal by the PLC of control system to servo-drive system, the X of servo-drive system starts to drive X to planker feed motion in the X-axis direction to servomotor, when alignment sensor touches hollow tube end, servo-drive system memory X is to the current location of servomotor, X still remains in operation to servomotor, while memory current location, the dsp processor of servo-drive system inside calculates servo target location, servo-drive system according to the servo target location control X calculated to driven by servomotor X to planker in the X-axis direction feeding move, after arriving target location, servo system control Y-direction driven by servomotor Y-direction planker in the Y-axis direction feeding moves the distance of setting, cutter cutting hollow pipe, hollow pipe thrown off by alignment sensor, cut rear base plate Y-direction under Y-direction driven by servomotor to reset, PLC sends enabling signal to servo-drive system, start next cutting process.
