Embodiment Construction

[0017] Such as figure 1 As shown, the control system of the servo power turret control device of the present invention includes: a control power supply module, a power supply module, an embedded DSP main control module, a turret logic DSP control module, and a drive module. The control power supply module and the power supply module respectively provide control power supply and power supply to the embedded DSP main control module. The turret logic DSP control module is responsible for receiving the user's input signal and decoding the signal into an index signal, and then sending the index signal to the embedded DSP main control module through the CAN bus, and outputting the turret status signal and fault in real time Test results. The embedded DSP main control module drives the servo motor to the target position after receiving the index signal sent by the turret logic DSP control module. At the same time, the embedded DSP main control module also sends the turret position ...

Abstract

The invention provides a control device for a servo power turret, which relates to a machine tool. A fully digital DSP processing chip, two central processing units (CPU), an embedded DSP main control module and a turret logical DSP control module are adopted by the device, wherein the embedded DSP main control module is a servo motor position control unit using TMS320LF2407 as a main processor, and the current, the position and the speed of a motor are controlled closely; the turret logical DSP control module is a user input / output management module using TMS320LF2406 as a co-processor; 74HC573 is used as a bus driving chip; and a push-pull output circuit of MOFET is adopted. The servo control turret has high transposition speed, can reduce the tool changing time of the turret, can improve the processing efficiency, the transposition precision and the tool changing accuracy of the machine tool, and can also improve the flexibility and the universality of control.

Description

technical field [0001] The invention relates to a servo power turret on a machine tool in an equipment manufacturing industry, in particular to a control device for a servo power turret. Background technique [0002] At present, the main problems of pure electric turrets are complex structure, high failure rate, difficult maintenance, small locking force of cutter head, not suitable for heavy cutting, easy overload and burning of drive motor, easy damage of decoding system under turning vibration, indexing rotation The bit speed is not easy to increase; the pure hydraulic turret has the disadvantages that the turret has high requirements on the quality of the hydraulic oil source, the turret indexing speed fluctuates due to the influence of oil temperature, the adjustment and maintenance are more complicated, and the price is higher. Contents of the invention [0003] In order to solve the shortcomings of the prior art, the object of the present invention is to propose a s...
