The advantage that the present invention adds provides in the specific embodiment description partly below, and part will become obviously from the following description, or recognizes by practice of the present invention.
Description of drawings
Fig. 1 is the front view of apparatus of the present invention.
Fig. 2 is the vertical view of apparatus of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further.
One, frame for movement of the present invention.
As shown in Figure 1 and Figure 2, building block of the present invention comprises: two-dimentional numerical control gantry cutting machine 1, plasma arc voltage are heightened the digital control system 6 of jacking system 2, plasma cutter 3, SERVO CONTROL jacking system 4, plasma/oxygen/combustion gas cutter sweep 5 and band tutorial function.
As shown in Figure 1 and Figure 2, plasma cutter 3 is installed in the plasma arc voltage and heightens on the jacking system 2, and plasma/oxygen/combustion gas cutter sweep 5 is installed on the SERVO CONTROL jacking system 4; The plasma arc voltage is heightened jacking system 2, SERVO CONTROL jacking system 4 is installed on the two-dimentional numerical control gantry cutting machine 1; The digital control system 6 of band tutorial function also is installed on the two-dimentional numerical control gantry cutting machine 1.Wherein, the plasma arc voltage is heightened the digital control system 6 of jacking system 2, plasma cutter 3 and band tutorial function and is formed first group of cutter sweep, and SERVO CONTROL jacking system 4 and plasma/oxygen/combustion gas cutter sweep 5 is formed second group of cutter sweep.
Above-mentioned plasma arc voltage is heightened jacking system 2, SERVO CONTROL jacking system 4, plasma cutter 3, plasma/oxygen/combustion gas cutter sweep 5 and is all adopted prior art.
Two, the method for operation of the present invention.
The present invention includes the cutting mode of straight line, circular arc and projection face on following two kinds of inclined-planes or the sphere.
Function one: on two-dimentional numerical control gantry cutting machine 1 basis, be equipped with the plasma arc voltage and heighten the digital control system 6 of jacking system 2, plasma cutter 3 and band tutorial function, can carry out the plasma cutting of straight line, circular arc and projection face on inclined-plane, sphere or the cylindrical shell.
Its operation principle is: in plasma cutting process, utilize the plasma arc voltage to heighten function, combining with digital control system this mode of 6(does not adopt its tutorial function) two-dimentional SERVO CONTROL, the geometry of workpiece is cut out required figure from dynamic height control.
Function two: on two-dimentional numerical control gantry cutting machine 1 basis, be equipped with the digital control system 6 of SERVO CONTROL jacking system 4, plasma/oxygen/combustion gas cutter sweep 5 and band tutorial function, adopt teaching or teaching to add programming mode, on the inclined-plane, sphere or cylindrical shell carry out plasma (or oxygen, the combustion gas) cutting of straight line, circular arc and projection face.
Its operation principle is: use SERVO CONTROL jacking system 4, carry out the location of sphere workpiece height and position value, the numerical value of giving behind the location is remembered programming by the digital control system 6 of band tutorial function, and control system is given the program point value SERVO CONTROL jacking system 4 current physical locations.When the define program section, can use arbitrary positional value programming.Block is with after adding in the program automatically and being inserted into the block of cursor indication.The CNC cursor will be positioned at the block of new edited, and editing area will be eliminated so that other blocks of spinning wheel.The storage of data and read by the software systems instrument and can programme to whole cutting process in advance, and can calculate general pitch time in advance.The program of finishing can directly import in the controller by system.Just can be cut by plasma/oxygen/combustion gas cutter sweep 5 behind the new workpiece material loading.
The implication of described " teaching " is: when robot replaces people's operation, must send indication to robot with Xi'an, stipulate that robot carries out the action that finish and the particular content of operation.This process just is called to the teaching of robot or to the programming of robot.Teaching to robot has diverse ways, wants to allow robot realize desired action, must give robot various information, at first is the information of robot motion order and the harmony messages of external equipment; Next is the additional conditions information with the machine man-hour; Be position and the attitude information of robot again.Specifically can be referring to document " Programming method for robot teaching, Zhang Aihong, Zhang Qiuju, Southern Yangtze University, School of Mechanical Engineering, Jiangsu, Wuxi 214000 "
Below above-mentioned functions one and function two are compared explanation:
The difference of function one and function two is: function one is used for cutting plate level or little gradient workpiece; Function two is that teaching adds cutting, is used for cutting sphere or the big workpiece of gradient.Function one is heightened tracking altitude control cutting by arc voltage; Function two is sought space tracking and is cut by the teach programming function of digital control system, highly controls in the tutorial function to add axis servomotor control.
The mechanism that function one and function two adopt is not only similar but also have any different.When cutting flat board and little gradient workpiece, only need direct function of use one, heighten tracking altitude control cutting, efficient height by arc voltage; But when the big gradient groove of cutting or spheroid, because track is the locus, the burning torch head stops cutting process if collide the inclined-plane easily by the arc voltage tracking altitude.Therefore, need function of use two by the teach programming function of digital control system, add the highly locus of searching cutting track of axis servomotor control, the locus point of cutting track is read in digital control system programme, cut again.Function one can not be used for teaching because not being equipped with axis servomotor, and function two is heightened and can not be used for finishing arc voltage and heighten cutting because not being equipped with arc voltage.This is based at most three of the controls of existing digital control system, therefore can not control servo rail simultaneously and arc voltage is heightened, thereby can only divide two kinds of controls finish the cutting of two dimensional surface and the big gradient of three dimensions and sphere at an equipment.
Above-described only is preferred embodiment of the present invention, the invention is not restricted to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite that does not break away from basic design of the present invention, all should think to be included within protection scope of the present invention.
