A stepping motor of the full-automatic grinding and polishing machine works to drive a transverse screw rod to rotate and a transverse nut is enabled to generate axial displacement along the transverse screw rod, so that a manipulator fixing frame moves forwards; in the process of moving forwards, a manipulator clips out a grinding and polishing disk; a longitudinal screw rod rotates, a longitudinal nut drives the manipulator to move down; and the grinding and polishing disk is placed on a grinding and polishing seat and then the manipulator returns to the original position, so that automatic installation of the grinding and polishing disk is implemented. A rotating shaft screw rod moves up and down under the drive by a motor at the bottom of a rack; in the moving process of the rotating shaft screw rod, an integral spindle is driven to rotate by a rotating fixed plate and a rotating fixed seat until a grinding and polishing head on the spindle moves to the position suitable for polishing. Then, a clamp is placed on a grinding and polishing disk assembly; after the grinding and polishing head is fixed with the clamp, polishing is carried out; and after polishing is completed, the grinding and polishing head drives the clamp to move into an ultrasonic washing box to carry out washing, so that works of automatically moving, washing and the like are completed. Working efficiency is obviously improved.
Description
Technical field
The present invention relates to a kind of polished machine.Described polished machine is mainly used in the grinding and polishing of metallographic specimen.
Background technology
Metallographic Analysis is the important means of carrying out the metal material performance study, and the Metallographic Analysis result is the important referential data of carrying out materials processing, formulating Technology for Heating Processing.The preparation quality of metallographic specimen directly affects the result of Metallographic Analysis.
Can not automatically complete a plurality of grinding and polishing dishes as the existing metallographic specimen polished machine of metallographic specimen Preparation equipment more changes jobs, while therefore changing the grinding and polishing dish, need operating personnel to select suitable grinding and polishing dish manual mode of operation to be arranged on the grinding and polishing seat, this substitute mode is not only required great effort, and operating efficiency is lower.In addition, existing polished machine does not have the function of automatic washed samples, and sample, after grinding and polishing, needs staff's manual mode of operation that sample is taken off and cleaned, and operating efficiency is low.
Also there is following technological deficiency in existing metallographic specimen polished machine:
The first, existing metallographic specimen polished machine generally relies on motor and belt drives grinding and polishing dish to rotate, and this kind of drive not only takies larger space, and belt transmission easily skids, thus transmission accuracy and stability not high enough.In addition existing grinding and polishing dish can't be on the grinding and polishing seat automatic capturing, and there is no positioner between grinding and polishing dish and grinding and polishing seat, so the easy run-off the straight of grinding and polishing dish or the rising do not expected.
The second, existing metallographic specimen polished machine, the lead-in mode of its grinding and polishing dish lapping liquid is: it is suitable in advance the ratio of water and lapping liquid to be regulated, then with water pump by the fluid drips that regulates on the grinding and polishing dish.Due to needs pre-coordination lapping liquid, operational sequence more complicated; The importing of lapping liquid is dropping type in addition, and this lead-in mode can not be injected on whole grinding and polishing dish equably, and the result of use of lapping liquid is undesirable.
Three, existing metallographic specimen polished machine, its single-point pressurized sample clamper mainly comprises the sample holder dish with connecting axle, be provided with several samples on described sample holder dish and place through hole, during use, sample is placed in through hole, the sample lower end leans against on mill, pressure is pushed up in upper end, this so-called single-point pressurization.Need when grinding and polishing finishes rear washed samples manually sample to be placed through hole and taken out one by one from the sample of sample holder dish, transfer in rinse bath, operating efficiency is lower.
Four, existing metallographic specimen polished machine, it is independent separately that its center pressing clip is held the sample holder hole of device, by bolt, cylindric sample top is pressed solidly in the sample holder hole fixed on separately respectively, not only fastness is poor with putting the fixed form contacted for this line, and sample easy to wear.
