Description
Technical field
The present invention relates to a kind of spindle of numerical control lathe position control and method thereof.
Background technology
At present, main shaft just carries out speed control conventionally, but in the situation that some are special, also needs main shaft to carry out Position Control.Such as: when work in-process carries out automatic tool changer in the heart, lathe all needs main shaft to be parked in accurately on a specific position when card engaging workpiece etc.The cardinal principle of FANUC main shaft of numerical control machine tool orientating function is that NC sends directional commands, by the rotaring signal on the position sensor on main shaft, main shaft is stopped on a definite position, and equally provides certain holding torque to servomotor position ring.This function can realize by increasing the mode of option main spindle's encoder.NC sends after directional commands, goes out 1 rotaring signal, and find main shaft stop position by position coder toothed disc resolution ratio by being arranged on the inner profile of tooth hair updo of position coder on main shaft, and each orientation does not need to remove system log (SYSLOG) main spindle's last time.But position coder cost is high, and procurement cycle is longer, but also be subject to supplier's limitation, even lathe need to carry out the transformation of mechanical erection aspect, installs very inconvenient.
Summary of the invention
For solving above technical deficiency, the invention provides a kind of cost low, easy for installation, spindle of numerical control lathe position control and the method thereof of accurate positioning.
The present invention is achieved by the following measures:
A kind of spindle of numerical control lathe position control of the present invention, comprise the spindle motor with power control module, described spindle motor drives and connects main shaft, on described main shaft, be provided with the block that can rotate with spindle synchronous, main shaft one side is provided with support, on support, be provided with the approach switch that block can be detected, described approach switch signal is connected with controller, and described controller signals connects the power control module of spindle motor.
The control method of spindle of numerical control lathe position control of the present invention, comprises the following steps:
Step 1, controller receives after the directional instructions that digital control system sends, and adjusts the merit of spindle motor
Rate, makes the near 100rpm of the speed of mainshaft;
Step 2, after the near 100rpm of the speed of mainshaft, approach switch starts to detect the block rotating with spindle synchronous, and when front and back detect block twice, in the time of will block being detected for the second time, the residing position of main shaft is classified as zero-bit;
Step 3, take zero-bit as starting point, and controller calculates main shaft and goes to the angle that desired location need to rotate, and calculates according to this angle value speed and the time parameter that spindle motor rotates, and sends to spindle motor.
The invention has the beneficial effects as follows: by approach switch, realize main shaft orientation, installation transformation is fairly simple, and cost is low, applied widely, and orientation accuracy is high, and cost performance is higher.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein: 1 controller, 2 spindle motors, 3 blocks, 4 main shafts, 5 approach switchs, 6 Timing Belts.
The specific embodiment
As shown in Figure 1, a kind of spindle of numerical control lathe 4 position controls of the present invention, have saved original position coder, and adopt the lower approach switch 5 of cost, and have made some in program and adjusted, and can complete well the directed and location of main shaft 4.
It comprises the spindle motor 2 with power control module, spindle motor 2 is driven and is connected main shaft 4 by Timing Belt 6, on main shaft 4, being provided with can be with the synchronous block 3 rotating of main shaft 4, main shaft 4 one sides are provided with support, on support, be provided with the approach switch 5 that block 3 can be detected, approach switch 5 signals are connected with controller 1, and controller 1 signal connects the power control module of spindle motor 2.
The control method of spindle of numerical control lathe 4 position controls of the present invention, comprises the following steps:
Step 1, controller 1 receives after the directional instructions that digital control system sends, and adjusts the merit of spindle motor 2
Rate, makes the near 100rpm of main shaft 4 rotating speed;
Step 2, after the near 100rpm of main shaft 4 rotating speed, approach switch 5 starts to detect with the synchronous block 3 rotating of main shaft 4, and when front and back detect block 3 twice, in the time of will block 3 being detected for the second time, the residing position of main shaft 4 is classified as zero-bit;
Step 3, take zero-bit as starting point, and controller 1 calculates main shaft 4 and goes to the angle that desired location need to rotate, and calculates according to this angle value speed and the time parameter that spindle motor 2 rotates, and sends to spindle motor 2.
Orientation accuracy contrast:
1, position coder orientation accuracy: external position coder rotation 1 circle, resolution ratio is 4096 pulses, that is: the every rotation of main shaft 41 °=4096 pulse/360 °=11.377 pulses, precision can reach 0.1 °
2, approach switch 5 orientation accuracies: approach switch 5 sends after 1 rotaring signal, system acquisition spindle motor 2 inner encoder positions, that is: precision is still calculated by encoder, the every rotation of main shaft 41 °=4096 pulse/360 °=11.377 pulses, precision can reach 0.1 ° by above contrast, and two kinds of mode orientation accuracies are identical.
Cost contrast:
1 position coder (Italian import): 1620 Euros, be roughly equal to 13446 yuan of RMB, comprise main shaft 4 gears, encoder, shaft coupling, communication cable, installation accessories.
2 approach switch 5 orientations (Purchased Item, self assembly): approach switch 5:75 unit; Self-control support: 40 yuan (two); 5 meters of shielded cables: 50 yuan; Power model plug (20 pin): 90 yuan; Amount to: 75+40+50+90=255 unit.By above calculating, approach switch 5 orientations, cost performance is higher.
The above is only the preferred embodiment of this patent; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the art of this patent principle; can also make some improvement and replacement, these improvement and replacement also should be considered as the protection domain of this patent.
