Specific implementation mode
Present disclosure is illustrated below by embodiment:
As shown in Figure 1 to Figure 3, the present invention provides a kind of rope saw, including rack 1, diamond bead string rope 2 and driving device 3.Multiple guide wheels 4 are installed in the rack 1, which connects from beginning to end is wrapped on multiple guide wheels 4 and tightens, should Driving device 3, which is mounted in the rack 1, drives the diamond bead string rope 2 to recycle cabling along guide wheel 4.When the diamond bead string rope 2 touch need cut workpiece when, the driving device 3 drive 2 cabling of diamond bead string rope, to workpiece formed cutting force into Row cutting.The driving device 3 can be motor or other can drive the device of the diamond bead string rope cabling.
The rack 1 is arch, which is cut across arcuate openings 5,5 alignment pieces of arcuate openings It cuts.1 arcuate openings of rack, 5 both sides are symmetrical arranged runing rest 6, and there are two peripheral surface rollings to support for installation on the runing rest 6 The support wheel 7 being close together corresponds to the diamond bead string rope 2 on the peripheral surface of the support wheel 7 and is equipped with annular groove 8, the gold Hard rock bead string rope 2 is passed through from the annular groove 8 among two support wheels 7, which can prevent the diamond string Pearl rope 2 in cabling stress and fall off.Two servo drive systems 9 that two runing rest 6 is correspondingly arranged, the servo drive system 9 are connected in the rack 1 and the runing rest 6 are driven to rotate, which drives the support wheel 7 rotation, makes the support Wheel 7 pushes down the diamond bead string rope 2 in the opposite direction of pressure along the diamond bead string rope 2 in cutting, is diamond Bead string rope provides the support force on stress negative direction, supports the Cutting indexes of diamond bead string rope.The rope saw can be adjusted flexibly Saw butt to, can preliminary working first be carried out to workpiece, then adjust sawing direction and fining-off is carried out to workpiece, by preliminary working and Fining-off combines, be not required to workpiece in preliminary working equipment after preliminary working be moved in fining-off equipment again carry out carefully plus Work saves place, improves cutting efficiency;The rope saw can also adjust sawing direction according to the profile of workpiece, can cut not The raw material of rule extend the workpiece range of its processing.Meanwhile in the case where ensureing allowance abundance, the rope saw Can with bulk material removal, the waste material size of removal is big, is no longer clast, repeats and utilizes, improves the utilization rate of material, Reduce cost.
Two support wheels 7 on the runing rest 6 are diagonally abutted together, and the support wheel 7 for being located at upside is biased to The center of the arcuate openings 5, when which cuts workpiece, the Impact direction of the diamond bead string rope 2 is usually towards arch The top of rack, the support wheel 7 of upside are biased to the center of the arcuate openings 5, to support the diamond bead string rope 2 more firm Gu preventing diamond bead string rope 2 from falling off, the stability of the operation of the rope saw is improved.
The servo drive system 9 is mounted on the inner side edge of the arcuate openings 5, and 9 relative symmetry of servo drive system is arranged, Make rope saw uniform force in cutting, is hardly damaged.
The pressure side being subject to when cutting object for detecting the diamond bead string rope 2 is equipped in the servo drive system 9 To sensing device.The sensing device can detect 2 stress side of diamond bead string rope according to 2 cutting line of diamond bead string rope at any time To the servo drive system 9 adjusts runing rest 6 at any time according to the signal of sensing device, which drives the support wheel 7 rotate at any time, provide the support force on stress negative direction for diamond bead string rope 2, therefore the rope saw can in cutting process To adjust cut direction at any time, cutting line is varied, can arbitrarily move in three dimensions, be no longer limited to general NC The processing of equipment both direction improves the efficiency of work pieces process.
The guide wheel 4 is corresponded in the rack and is equipped with mounting hole 10, and the guide wheel 4 is mounted in the mounting hole 10, the guide wheel 4 It is hidden in the mounting hole, which is protected.The diamond bead string rope 2 is corresponded on the lateral surface of the rack 1 to be equipped with away Wire casing 11, the diamond bead string rope 2 continuous cabling in the cabling channel 11 avoid the diamond bead string rope 2 from being exposed to outside, Increase aesthetics.
The guide wheel 4 is mounted on by bearing in the mounting hole 10, and the frictional force of the guide wheel 4 rotation is small, improves cutting Efficiency.
It is also associated at least one tensioning apparatus 12 in the rack 1, which includes tensioning wheel 13, mounting bracket 14 With spring 15, which is movably connected in the rack 1, and the tensioning wheel 13 rotation is articulated on the mounting bracket 14, the bullet Spring 15 applies elasticity to the mounting bracket 14 makes the tensioning wheel 13 push down the diamond bead string rope 2.The tensioning apparatus 12 is to the Buddha's warrior attendant Stone bead string rope 2 is tensioned, and is kept the diamond bead string rope 2 to remain tensioning state in cutting, is improved cutting efficiency.
The mounting bracket 14 is bolted in the rack 1.
The position at 1 face arcuate openings of rack, 5 center is set there are one guide wheel 4, which is two, and two should Tensioning apparatus 12 is separately positioned on the both sides of the guide wheel 4 on 1 face arcuate openings of rack, 5 center.Two tensioning dresses It sets 12 pairs of diamond bead string ropes 2 and carries out symmetric tensioning pole, improve rate of tension, further increase cutting efficiency.
1 middle part of rack is equipped with attachment device 16, which can connect the rack and robot arm, machine Device human arm can provide a rotary freedom, further increase the cutting angle of the rope saw, realize that rope saw is arbitrarily square To sawing, cutting efficiency is improved.The attachment device 16 can realize interlocking with flange, which can be with robot arm Flanged joint may be implemented the rope saw and rapidly be changed from the robot arm, improves cutting efficiency.
The above, only present pre-ferred embodiments, therefore cannot limit the scope of implementation of the present invention according to this, i.e., according to Equivalent changes and modifications made by the scope of the claims of the present invention and description all should still belong in the range of the present invention covers.
