Abstract

An improved crystal grinder processing device comprises a grinding disc, a grinding disc rotary driving motor, a micro computer control system, a crystal line transfer control step motor, a crystal face transfer control step motor and a grinding disc elevation control step motor. The micro computer control system includes a sensor which is arranged near the grinding disc and the signal of which is output to an I/O port of the single chip microcomputer through an optical coupling isolation circuit; and a single chip microcomputer which receives the sensor signal and determines the rising speed of the grinding disc and outputs a corresponding control signal to the grinding disc elevation control step motor according to the grinding disc rotating speed and the depth of the crystal surface to be grinded. The utility model employs the method of grinding and rising of the grinding disc so as to solve the problems of breaking on the crystal surface, aging of the grinding disc and not lightness of the large-surface crystal.

Description

Improved quartzy grinding machine processing unit (plant)

Technical field

The utility model relates to sanding and polishing equipment, especially for crystal corase grind, fine grinding and polishing, by the grinding machine mill processing unit (plant) of microcomputerized control.

Background technology

Quartzy process is divided into 3 steps usually, and the first step is a corase grind, and second step was a correct grinding, and the 3rd step was polishing, and the mill that each step uses also has nothing in common with each other, and promptly corase grind uses roughing mill, correct grinding to use refiner discs, polishing to use polishing disk.Quartzy embryo has formed bright exquisitely carved quartzy finished product at last through the polishing of different mill pre-set programs.

In order to improve quartzy production efficiency, the general purpose control algorithm is directly mill to be raised to need the grinding depth place to postpone a period of time again, but in actual process following problem is arranged:

1, more crisp because of quartzy quality, mill directly top gets on, and crystal takes place easily be crushed;

2, along with the processing crystal individuality is increasing, buffed surface also increases, and directly the mill damage is got on to quicken in the top;

3, some mill driving three phase electric machine power is lower, and motor rotation blockage takes place easily, damages mill and motor.

The utility model content

The purpose of this utility model provides the quartzy grinding machine processing unit (plant) of a kind of improvement of avoiding crystal to be crushed, to prolong abrasive disk life-span.

This novel purpose is achieved in that a kind of improved quartzy grinding machine processing unit (plant), comprises, and mill, the mill rotary drive motor, microcomputer control system, quartzy line feed control step motor and crystal change face control step motor; Also has mill lifting control step motor;

Described microcomputer control system consists of:

Sensor: be arranged on the mill adjacent position, sensor signal exports the single-chip processor i/o mouth to by optical coupling isolation circuit;

Single-chip microcomputer: sensor-lodging, the comprehensive speed of grinding plate and the quartzy face degree of depth factor of waiting to polish are determined the mill rate of climb and are exported corresponding control signal to mill lifting control step motor.

Also has the console of forming by display, keyboard and control panel; Described single-chip microcomputer is connected with console by 485 communication interfaces.

Above-mentioned single-chip microcomputer model is LPC2138; Also having model is the expansion main control chip of ULN2003.

Also have two-way power voltage supply power supply: form the two-way voltage output of isolating by KA5L0380R, isolating transformer and feedback network ,+5V one tunnel gives described microcomputer control system power supply, and+24V one tunnel powers to external interface.

Problem at the prior art existence: this novel main thought is: rising edge polishing in mill limit is quartzy, and mill rises to assigned address, and the face polishing is finished.The rate of climb of mill combines factors such as mill type, mill are new and old, speed of grinding plate, the quartzy face degree of depth, quartzy face size.

This novel beneficial effect is:

1, quartzy face crudy raising, mill prolong service life

In the process,, speed of grinding plate new and old in conjunction with mill type, mill and factors such as the quartzy face degree of depth and quartzy face size are determined the suitable mill rate of climb, therefore, have avoided the problem that quartzy face breaks in the process, simultaneously, reduced the degree of aging of mill.

2, solved the technical barrier of the quartzy polishing of big face by the rising edge quartzy mode of polishing.

The specific embodiment

Fig. 1 Fig. 2 illustrates, this novel mill 1 that comprises, and mill rotary drive motor 2, microcomputer control system, quartzy line feed control step motor and crystal change face control step motor; Also has mill lifting control step motor 3;

Microcomputer control system consists of:

Sensor: be arranged on mill 1 adjacent position, sensor signal exports the single-chip processor i/o mouth to by optical coupling isolation circuit;

Single-chip microcomputer: sensor-lodging, the comprehensive speed of grinding plate and the quartzy face degree of depth factor of waiting to polish are determined the mill rate of climb and are exported corresponding control signal to mill lifting control step motor (referring to Fig. 2).

Referring to Fig. 3, utilize KA5L0380R, isolating transformer, feedback network to form the two-way voltage of isolating and export ,+5V one tunnel powers to system, and+24V one tunnel powers to external interface, reduces the interference of external environment condition to system.Adopt LPC2138 as main control chip, system is divided into four interfaces: 1, sensor input interface, and by light-coupled isolation, sensor signal is given controller, and controller carries out logic control according to sensor states; 2, forceful electric power output interface, the driving force rear drive relay by ULN2003 expansion main control chip drives contactor by relay, the running of control three phase electric machine; 3, stepper motor delivery outlet, the I/O of main control chip by light-coupled isolation after, directly drive stepper motor driver; 4,485 communication interfaces, by communication interface, customer parameter/control command etc. is accurately obtained in master control, thus the control task of finishing.

Working procedure:

1, parameter setting: comprise line parameter, face parameter and systematic parameter;

2, parameter is preserved into console, sends to master control during startup;

3, start procedure on the console;

4, master control is according to the position of the quartzy row of parameter, face, and mill rises subsequently, and the operation of the face of changing;

5, finish after mill descend by parameter;

6, polishing.

The operation of polishing: corase grind; Correct grinding; Polishing.
