It can also be seen that from Fig. 3 the bottom surface of carriage 32 is provided with reinforcement 322, its objective is in order to increase the support strength of carriage 32.

In order to reduce cost, carriage 32 is made of one with macro-axis 31 upper ends 311; In order to improve strength of joint, the important actor that one projection is set in the central authorities and macro-axis 31 junctions of carriage 32 bottoms.

In order to strengthen the stability of this equipment when operating, also set up counterweight 53 in lower house 5 bottoms.

Axle sleeve 521 also can replace using with bearing.

With reference to Fig. 4, Fig. 5, Fig. 6, the cylindrical boss 333 upper edge axis directions that described pallet 33 centre of surface positions are provided with offer the notch 334 of three symmetrical distributions, three notches 334 connect mutually, notch 334 extends to pallet 33, make the surface of pallet 33 form three grooves 335, these three grooves 335 slightly outwards radiate certain length from the center of pallet 33, in the notch 334 of above-mentioned boss 333, set up one and carry frame 35, this profile of carrying frame 35 should be coincide mutually with the void shape that three notches 334 offering on the boss 333 are constituted, the lower end of carrying frame 35 have three radially distribute carry frame pin 351, the described profile of carrying frame pin 351 also should be coincide mutually with the void shape that three grooves 335 on pallet 33 surfaces are reserved, and the effect of carrying frame 35 is to be used for will placing easily the laser disc 8 on the pallet 33 to take out.

With reference to Fig. 7; protection switch 9 has adopted contact formula normally closed switch in the present embodiment; protection switch 9 is fixed on the suitable position of the upper bracket 42 in the loam cake 4; protection switch 9 is made of fixed touching plate 91 and movable contact spring 92; probe 93 is arranged on the below of a movable contact spring 92 of protection switch 9; this probe 93 is by little spring 94 returns; the edge of the head points laser disc 8 of probe 93; the purpose of setting up protection switch 9 is in order to prevent from not have laser disc 8 on pallet 33, and the phenomenon that causes bistrique 251 to damage pallets 33 owing to the machine of opening by mistake takes place.

In conjunction with above-mentioned accompanying drawing, the course of work of the present utility model is:

Open hasp 41, open loam cake 4, back out fastening nut 34, put into laser disc 8, tighten nut 34, put into brilliant polish in pallet 33, loam cake 4 closes, shut hasp 41, the probe 93 of protection switch 9 is by laser disc 8 jack-up, protection switch 9 closures, and control circuit 1 is connected, opening power, control circuit 1 picks up counting; Motor 6 rotates, and top driven gear 62 engagements by on top driving gear 61 and the little axle 21 drive rubbing head assembly 2 high speed rotating by little axle 21.Following pressure ring 24 in the rubbing head 2, snap ring 25, bistrique 251 are under the effect of big spring 23, can regulate height automatically, and guaranteed that bistrique 251 can balancedly be pressed on the laser disc 8, bistrique 251 high speed rotating, produce friction with laser disc 8, be issued to the purpose of polishing laser disc 8 in the effect of brilliant polish.Simultaneously, change speed motor 7 slow rotation, by 72 engagements of the bottom driven gear on bottom driving gear 71 and the macro-axis 31, macro-axis 31 drives carriage 32 and rotates, be placed on the pallet 33 on the carriage 32 and place laser disc 8 interlocks of pallet 33, laser disc 8 rotates at a slow speed, reaches the purpose that changes laser disc 8 polishing positions.When the polishing time of setting reached, power supply was closed automatically, certainly, and when the polishing time of setting does not reach, also can the manual-lock power supply, hasp 41 is opened in this moment motor 6, change speed motor 7 equal stalls, opens loam cake 4, back out fastening nut 34, mention frame 35, laser disc 8 can take out.

As in polishing process, motor 6 is being worked, and opens loam cake 4 this moment; or when not putting into laser disc 8 opening power, the probe 93 of protection switch 9 ejects under the effect of little spring 94, protection switch 9 is closed; control circuit 1 disconnects, and dump plays the effect of protection pallet 33.

The utility model has been owing to adopted said structure, so production cost is very low, and stable work in work, operates very easyly, and the noise during work is also lower.

Because the periphery at pallet is provided with the tray wall that a circle raises up, and therefore can prevent spilling of brilliant polish effectively.Owing in boss, have additional and carry frame, can will place the laser disc on the pallet to take out very easily.

Owing to be provided with a big spring in rubbing head, bistrique can move up and down voluntarily, and has guaranteed that bistrique can balancedly be pressed on the laser disc surface, has improved polishing effect.

Owing in the control circuit of laser disc burnisher, set up protection switch, when therefore having stopped fully on pallet, not have laser disc, caused bistrique to damage the phenomenon of pallet because of opening by mistake machine.
