As shown in Fig. 1 to Fig. 9, the present invention comprises the polishing system 4 that is arranged on the frame 1, and described polishing system 4 comprises the polishing assembly that is positioned at the support plate 43 top and is positioned at the driving assembly below the support plate 43, and the polishing assembly includes The first transmission wheel 42 (big ring gear), the throwing wheel 45, the cross turret 410 and the swing assembly 41, the driving assembly includes the main shaft system 49 and its driving device composed of the main shaft 498 and the rotating drum 494; the main shaft 498 is installed on the bearing with seat 497, the belt seat bearing 497 is fixed on the bracket plate 43, and the first transmission wheel 42 and the main shaft 498 are coaxially fixed on the upper surface of the bracket plate 43;

The throwing wheel 45 is fixed on the top of the main shaft 498 by clamping nuts, and the first driving device (including a driven pulley fixedly installed on the bottom of the main shaft, a large motor, a main pulley and a belt on the output shaft of the large motor) drives the main shaft 498 to drive the throwing wheel 498. Wheel 45 rotates at high speed;

The rotating cylinder 494 is installed on the main shaft 498 through bearings, the cross turret 410 is fixed on the top of the rotating cylinder 494, and the second driving device (including a large sprocket, a reducer, a small sprocket and a chain fixed on the bottom of the rotating cylinder by screws) drives Rotating cylinder 494 drives cross turret 410 to rotate slowly;

Assembly of swing components:

The swing assembly 41 includes a swing shaft 4119. The swing shaft 4119 is sequentially provided with a swing rod 4113, a second and a third transmission wheel 4121, 4122 from top to bottom, and the second transmission wheel 4121 and the third transmission wheel 4122 are connected by screws. Fixed together, the outer peripheral surface of the center hole of the swing rod 4113 is covered with a swing torsion spring 4112, one end of the swing rod 4113 is provided with a hollow shaft 417, and the other end is provided with a small shaft 4114 with a roller 4117 at the bottom.

The hollow shaft 417 passes through the hole of the eccentric sleeve 415, and the eccentric sleeve 415 is fixed in the inner hole of one end of the swing rod 4113 by a set screw, and the workpiece installation core 4110 is fixed on the top of the hollow shaft 417 by a set screw, and the rubber ring 4111 is tightened. Installed in the groove on the side of the workpiece installation core 4110; the cup bottom workpiece 419 is sleeved on the workpiece installation core 4110, and is in contact with the throwing wheel 45; the fourth transmission wheel 411 is fixed on the lower end of the hollow shaft 417 by set screws; the third transmission wheel When 4122 meshes with the first transmission wheel 42 and rotates, the hollow shaft 417 is driven to rotate by the second transmission wheel 4121 and the fourth transmission wheel 411, thereby driving the component 419 to rotate;

When the swing assembly 41 is assembled, rotating the eccentric sleeve 415 can facilitate the installation and tensioning of the timing belts that drive the second and fourth transmission wheels.

The ejector rod 416 passes through the hollow shaft 417, the lower end of the return spring 4124 is fixed on the lower part of the ejector rod 416, and the upper end is in contact with the lower end of the hollow shaft 417;

The ends of the turrets of the cross turret 410 are fixedly connected to the tops of the swing shafts 4119 of a group of swing assemblies respectively; the swing assembly 41 slowly rotates around the rotating drum 494 with the turn frame 410, and the swing torsion spring 4112 makes the swing rods swing around the swing shafts 4119 , thereby the cup bottom workpiece 419 is compressed on the throwing wheel 45.

Limiting block 48, travel switch 47 and electromagnet 46 fix the upper and lower sides of bracket plate 43 respectively, when roller 4117 touches limiting block 48, limiting block 48 pushes roller 4117 to make swing bar swing around swing shaft 4119, at this moment the cup The bottom workpiece 419 leaves the throwing wheel 45; when the small shaft 4114 hits the travel switch 47, the electromagnet 46 acts to push the ejector rod 416 to rise, and the cup bottom workpiece 419 is pushed away from the workpiece installation core 4110 and falls, along the discharge direction. Groove 6 slides down in the collection frame 8;

The operator puts the workpiece at the bottom of the cup to be processed on the workpiece installation core 4110, and as the turret 410 continues to rotate, when the roller 4117 leaves the limit block 48, the swing torsion spring 4112 makes the swing rod swing around the swing shaft 4119, thereby Cup bottom workpiece 419 is pressed on throwing wheel 45.

The upper end of the transparent cover plate 2 is fixed on the frame 1, which can prevent the workpiece 419 at the bottom of the cup from being lifted by the electromagnet 46, and at the same time, create a relatively closed space to reduce dust pollution. On the dust removal system of the workshop, the polishing dust is sucked away immediately. Simultaneously because the transparent cover plate is transparent, it is convenient to observe the operation of the mechanism.

The baffle plate 3 fixed on the frame 1 and the turntable 44 fixed on the cross turret 410 are installed on the same plane, forming an isolation together to prevent the workpiece from falling between the moving mechanisms and hindering the operation of the equipment.

The feeding system 7 can be customized from the vibrating plate manufacturer, and the workpieces are arranged neatly without workers' operation, thereby improving production efficiency.
