Abstract
A receiving control device belongs to the technical field of machine cutting. At present, automatic loaders and unloaders are widely applied in small and medium bearing lathes, but for medium and large bearing lathes, the drive power of an automatic receiving device which adopts the drive control of a conventional air cylinder is not enough for articles which have larger volume and heavier weight, so the articles cannot be received, and moreover, the air cylinder drive has the defects of slow operation speed, inaccurate location, less controllable positions, difficult adjustment positions and speeds and the like. According to the utility model, a servo drive is used to drive a servo motor, the servo motor is used to drive a receiving manipulator, so the quick and accurate location control of three positions of the receiving of the receiving manipulator, blanking and returning to a normal position is realized.
Description
Technical field
The utility model relates to the machine cut technical field.
Background technology
At present, in the middle-size and small-size bearing lathe, automatic loading and unloading device is extensive use, but medium-and-large-sized bearing with lathe in; The product bigger for volume, that body weight is heavier, automatic material connection device is if adopt the traditional air cylinder drive controlling; The power of its driving is not enough, can't realize accessing of product, and air cylinder driven exists the speed of service slow; The location is inaccurate, and controllable position is few, and position and speed are difficult for shortcomings such as adjustment.
The utility model content
The purpose of the utility model is exactly through the servo driver drives servomotor, drives the hand that connects material through servomotor, accurate localization fast, and the hand of realizing connecting material connects material → loop control of three positions of blanking → reposition.
A kind of control device that connects material comprises servomotor (1), servo-driver (2); PLC (3), travel switch (4), pulley sheaves (5); The control circuit that belt wheel (6) and the hand that connects material (7) are formed, servomotor (1) provides electrical source of power by servo-driver (2), and axle head links to each other with pulley sheaves (5); Drive the hand (7) that connects material through belt wheel (6) and move, travel switch (4) be used to realize the to connect material original point return action of hand.The hand that connects material need be controlled its three position locations altogether; These three position datas are with the form writing servo driver of parameter, and deposit the internal drive register in, during actual motion; Send position command by two output points of PLC to driver; Driver makes up the position of judging that the hand that connects material need be located through the different conditions of these two PLC signals, and the control servomotor turns round to the target location, the electric machine built-in high resolution encoder; Accurately feed back motor actual motion position, reach the accurate location of the hand that connects material.
Through this method control hand location that connects material, on hardware, all adopt the plug-type line, easy-to-connect disturbs for a short time, easy to maintenance, and the position all only need just can be realized through modification driver relevant parameter with the speed adjustment.
Description of drawings
Fig. 1 is the structural representation of the utility model device.
The specific embodiment
Be described in detail below in conjunction with the specific embodiment of accompanying drawing the utility model.As shown in Figure 1, comprise servomotor (1), servo-driver (2); PLC (3), travel switch (4) pulley sheaves (5), the control circuit that belt wheel (6) and the hand that connects material (7) are formed; After the lathe energising, the hand that connects material must carry out the original point return operation earlier, and the former spot speed of returning that configures with parameter P1 is earlier moved; To running into travel switch (4), the speed of setting with parameter P2 runs slowly to stopping in the other direction, and driver sends initial point arriving signal X0 to PLC; Represent back former point operation completion,, all be set at 0 at parameter P10 and P11 place with the origin position of this position as the hand that connects material.
Motor one changes its internal encoder and sends N pulse; The hand that connects material is connected to motor side through belt wheel and pulley sheaves; Can draw motor one commentaries on classics; The pulley sheaves that drives turns over the circumference L in a week, then can calculate required rotating speed that turns over of motor and unnecessary umber of pulse according to the connect material distance of position and blanking position and origin position of the hand that connects material.As; The position and the hand origin position distance that connects material of connecting material is L1, and the hand that then connects material moves to the position that connects material from initial point, and motor need turn over L1/L to be changeed; Umber of pulse is N*L1/L; The gained revolution can be divided into gained integer circle with it and add unnecessary umber of pulse if not integer, is set in respectively among parameter P12 and the P13; The subordinate material level that connects material is put also and is set through parameter P14 and P15 in the same way.
After adjusting above-mentioned three positions, send the positioning starting order through PLC output point Y0 to servo-driver, driver makes up the hand position order that connects material of judging according to the different conditions of two output point Y1 of PLC and Y2 again; Like Y1: Y2=0: 1, then the expression hand that connects material need move to the position that connects material, and motor rotates; When the umber of pulse of sending when its encoder reaches the value that relevant parameter sets; Motor stops, and driver is accomplished signal X1 to PLC output location, thereby reaches the accurate location of the hand that connects material.
Use this method, only need can adjust the physical location of three positions of hand that connect material through changing the value of parameter P10 to P15, the locating speed of each position of hand that connects material, the acceleration and deceleration time all can be adjusted through setting relevant parameters respectively, and is simple to operation.And motor overload occurs or locatees situation such as not in place, and driver meeting display alarm plays a protective role.
Claims (1)
1. the control device that connects material comprises servomotor (1), servo-driver (2); PLC (3), travel switch (4), pulley sheaves (5); The control circuit that belt wheel (6) and the hand that connects material (7) are formed, servomotor (1) provides electrical source of power by servo-driver (2), and axle head links to each other with pulley sheaves (5); Drive the hand (7) that connects material through belt wheel (6) and move, travel switch (4) be used to realize the to connect material original point return action of hand.
