Abstract
The utility model discloses a fast feed-to-working feed photoelectric conversion device of a band sawing machine, and relates to an electromechanical conversion device of a metal cutting machine tool. The fast feed-to-working feed photoelectric conversion device of the band sawing machine comprises a laser transmission element, a photoelectric receiving element, a PLC (programmable logic controller) and a numerical-control system, wherein a saw frame is quickly lowered from an origin point. When the laser beam of the saw frame is blocked by a workpiece, and a photoelectric sensor cannot receive a signal, the rotation speed of a servo motor is immediately converted to the working feed speed from the fast speed, the fast feed-to-working feed conversion position of the machine tool is the initial sawing position, and the initial coordinate position is recorded and stored by the numerical-control system. The device has the advantages that the function of real-time detection of initial coordinates is realized, the resetting performance of the machine tool is good, the empty travel time is reliably reduced, the working efficiency of the machine tool is improved, and the accidental damage to band saw blades is prevented.
Description
Technical field
The utility model relates to the electromechanical transformation apparatus in a kind of Metal Cutting Machine Tool, is specifically related to a kind of band sawing machine F.F. opto-electronic conversion worker motion device.
Background technology
All band sawing machines are before sawing work, for the ease of workpiece loading and unloading, its saw frame is all away from workpiece, and the cutter of the lathe idle stroke that this segment distance is lathe from the peak to the surface of the work is for the no-load speed that improves the work efficiency lathe will be much larger than normal cutwork feed speed.Because bands for band is a kind of very thin, fragile rapid wear cutting tools, when surface of the work is arrived in bands for band sawing just, power can not withstand shocks, if the feed speed of this moment is too fast, in time be not transformed into the worker and advance sawing speed, will cause the collision of bands for band and workpiece, draw tooth, fracture, damage bands for band.Usually small-sized band sawing machine has a plate washer in direction of feed, and this plate washer stretches out the front at bands for band, after this plate washer is run into workpiece, promotes microswitch, makes the saw frame feed speed be transformed into work speed.But it is too big because taking up space for this mechanism of large-scale band sawing machine, so it is and inapplicable, the band sawing machine that does not have F.F. conversion worker motion device, the workman is in order to prevent from breaking bands for band palpus careful operation, therefore waste time and energy, the utility model takes the photo-electric control technology to realize that F.F. changes the worker automatically and advance for this reason.
The utility model content
The purpose of utility model: in order to overcome the deficiency that exists in the prior art, the utility model provides a kind of band sawing machine F.F. opto-electronic conversion worker motion device, reduce the null time reliably, improve the lathe operating efficiency, prevent the bands for band accidental damage, and have the function of the initial coordinate position of real-time detection sawing.
Technical scheme: a kind of band sawing machine F.F. opto-electronic conversion worker motion device, comprise Laser emission element, photoelectric apparatus, digital control system, PLC, described Laser emission element and photoelectric apparatus are installed in the saw kerf two ends of saw frame, and the Laser emission element gives off laser beam and received by photoelectric apparatus; Digital control system is installed on the saw frame, and PLC is connected on the digital control system.
As preferably, be placed on the workbench by sawing workpieces.
Beneficial effect: the utility model has utilized the technology of photoelectric sensing, saw frame descends fast from initial point, when the saw frame laser beam is lived by the workpiece shelves, when photoelectric sensor does not receive signal, the rotating speed of servomotor is from being transformed into work speed fast immediately, the position that the position that lathe F.F. conversion this moment worker advances just begins sawing, this initial coordinate position is preserved by the digital control system of lathe, so the utlity model has the function of the initial coordinate of real-time detection, resetting property of lathe is good, simultaneously reduce the null time reliably, improve the lathe operating efficiency, prevent the bands for band accidental damage.
Description of drawings
Accompanying drawing 1 is the structural representation of embodiment in the utility model specific embodiment.
The specific embodiment
Embodiment:
A kind of band sawing machine F.F. opto-electronic conversion worker motion device as shown in the figure, comprise Laser emission element 1, photoelectric apparatus 2, digital control system 3, PLC4, Laser emission element 1 and photoelectric apparatus 2 are installed in the saw kerf two ends of saw frame 6, and Laser emission element 1 gives off laser beam and 5 received by photoelectric apparatus 2; Digital control system 3 is installed on the saw frame 6, and PLC4 is connected on the digital control system 3.
Band sawing machine F.F. opto-electronic conversion worker motion device, sawing workpieces 7 is fixed on the tool stand 8 among the figure, Laser emission element 1, give off laser beam 5, as not lived for 7 grades by sawing workpieces, photoelectric apparatus 2 is to receive Laser emission element 1, penetrates the laser beam 5 that comes, the servomotor of lathe changes soon, as penetrate next laser beam 5, lived photoelectric apparatus 3 for 7 grades by sawing workpieces, just do not receive signal, the rotating speed of lathe servomotor is transformed into default sawing work feed speed immediately, finishes F.F. conversion worker and advances, and lathe saw frame coordinate position is preserved.
The above only is preferred embodiment of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
