Description
Technical field
The utility model relates to a kind of processing work and the quick convergence control circuit of cutter
.
Background technology
With the bearing grinder is example; The feed speed of emery wheel when actual grinding determined by technological requirement; Can not at will improve, but because the dispersiveness of workpiece blank size, when the process of establishment self-acting grinding machine; For fear of the unreasonable collision of workpiece and emery wheel, always, workpiece just gets into grinding process when also not touching emery wheel in advance.In order to improve the operating efficiency of grinding machine to greatest extent, desirable state should be workpiece and the quick convergence of emery wheel, changes grinding process at once in the contact.The quick convergence technical costs of traditional acoustic control is very high, because homemade sensor technology does not reach a standard, the actual effect of using is bad always again.
The utility model content
The purpose of the utility model provides a kind of processing work and the quick convergence control circuit of cutter, solves existing cost height of the quick convergence technical scheme of present processing work and cutter and the bad problem of result of use.
The quick convergence control circuit of processing work and cutter comprises rectification module, inverter, voltage check device, MCU module, DSP module, driver module, current sensing means; Rectification module is connected with inverter; This inverter is connecting motor; Voltage check device and current sensing means are connected between rectification module and the inverter, and this voltage check device and the current sensing means other end then connect MCU module, DSP module respectively, and driver module connects inverter.
Said current sensing means is ear current sensor suddenly.
The quick convergence control circuit of said processing work and cutter also includes a personal-machine interface module, and this module is connected with the MCU module other end.
The beneficial effect of the utility model is: owing to be to adopt at a high speed ear current sensor measurement electric current suddenly, its reaction speed is less than 1 μ s.When workpiece touched emery wheel fast, the electric current of adorning the electric main shaft of emery wheel must respond, and the ear current sensor is just measured this signal come suddenly, and through fast processing, in time sent instruction to master control set.
Description of drawings
Fig. 1 is the circuit theory diagrams among the embodiment;
1. rectification modules among the figure, 2. inverter, 3. voltage check device, 4. ear current sensor, 5. human-machine interface module, 6. MCU module, 7. DSP module, 8. driver module suddenly.
The specific embodiment
Please refer to Fig. 1, this control circuit includes rectification module 1, inverter 2, voltage check device 3, MCU module 6, human-machine interface module 5, DSP module 7, driver module 8, current sensing means; Rectification module 1 is connected with inverter 2; This inverter 2 is connecting motor; Voltage check device 3 and current sensing means are connected between rectification module 1 and the inverter 2; This voltage check device 3 and the current sensing means other end then connect MCU module 6, DSP module 7 respectively, and driver module 8 connects inverter 2, and MCU module 6 other ends connect human-machine interface module 5.In practical application, generally use suddenly ear current sensor 4 as current sensing means.
Measure and processing speed in order to improve to greatest extent; The load current signal that the current sensor of ear suddenly 4 that driving power is inner records carries out hardware filtering to be handled; Compare with the no-load current signal that configures again; In case load current surpasses the no-load current value in approach procedure, just sending signal from lead-out terminal at once informs that controller changes grinding process at once over to.
