Referring to the working relationship of the surface polishing apparatus of the workpiece configured as described above is as follows.

Figure 7 is a perspective view showing the workpiece seated on the conveyor belt of the present invention, Figure 8 is a front view showing the operation relationship of the surface polishing apparatus of the workpiece according to the present invention.

As shown in FIGS. 7 and 8, the polishing apparatus 10 of the present invention is first manufactured by the first motor 206 of the moving means 200 and the power generating unit 400 by the operation of the controller 600. When the power is applied to each of the two motors 406, the conveyor belt 208 is rotated while the first and second pulleys 202 and 202a connected to the first motor 206 of the moving means 200 rotate. It will rotate in one direction.

In addition, the pair of pulleys 412 connected to the second motor 406 and the belt 416 of the power generating unit 400 is connected to the driven pulley 304 of the polishing means 300 while rotating. The grinding wheels 306 are rotated by the belts 414.

In this state, the worker seats the workpiece W manufactured by a press die or the like on the upper portion of the conveyor belt 208. That is, when the workpiece W is seated on the conveyor belt 208, the workpiece W is It is seated by being caught by the protrusion 210 formed on the conveyor belt 208.

Thus, the workpiece W seated on the conveyor belt 208 is continuously moved while moving in one direction by the rotation of the conveyor belt 208 while passing through the top of the guide member 424, the guide member 424 The upper portion of the workpiece (W) entered into the top of the) is supported by the bearing 426 is to be moved safely to prevent shaking or departure.

On the other hand, the workpiece (W) seated on the upper portion of the conveyor belt 208 is a workpiece (W) that is moved in a state supported by the bearing 426 and the guide member 424 is the polishing of the polishing means 300 Passing through the part 301, both sides of the workpiece (W) is polished by a plurality of grindstones 306 provided on both sides of the conveyor belt 208 when passing through the grinding unit 301.

Therefore, the workpiece W polished on both sides by the grindstone 306 continues to move in the opposite direction through the conveyor belt 208 and is discharged.

At this time, when polishing both sides of the workpiece (W) by sequentially performing the polishing operation by a plurality of grindstone 306, both sides of the workpiece (W) is polished smoothly and precisely to obtain a high-quality workpiece. .

Therefore, by simply placing the plurality of workpieces (W) in the upper portion of the conveyor belt 208 in this way, the automatic movement to polish both sides while moving the workpiece (W) automatically to produce a large amount of workpieces (W) in a short time. It is possible to polish the side of the.

In addition, the dust generated when the workpiece (W) is polished by the grinding wheel 306 is the dust removal member 502 through the through hole 103 formed in the upper plate 102 of the base 100 It is sucked into the suction port 504 of the discharge port 506 is connected to the discharge through the discharge pipe 508.

In addition, the dust generated when the side surface of the workpiece (W) is polished by the cover member 520 can be prevented from scattering to other areas such as the workplace and at the same time, it is possible to prevent safety accidents that may occur during polishing. .

In addition, when the grindstone 306 is worn by the polishing operation of the workpiece W moved by the conveyor belt 208, when the handle 326 of the gap adjusting means 320 is turned in one direction, the screw shaft ( 322 by the slide plate 310 is advanced in the direction of the conveyor belt 208 according to the guide of the second rail 316 of the fixed plate 314 by adjusting the desired interval by the operator to perform the polishing operation The same polishing effect as the first one can be obtained.

And, if the wear of the whetstone 306 is severe to replace the slide plate 310 by using the handle 326, after replacing the whetstone 306 and again using the handle 326 ( Workpiece W moved by the conveyor belt 208 by adjusting the proximity to the conveyor belt 208 to move the workpiece (W) by moving the grinding wheel 306 to perform the polishing operation of W) Both sides of the polishing will be polished.

Therefore, since the polishing apparatus 10 performs all the operations of polishing while moving the workpiece W automatically, the side surface of the workpiece W can be polished in a short time, and the workpiece W over a large number. It is possible to obtain a high quality workpiece (W) by polishing the side surface.

In the above, a preferred embodiment of the surface polishing apparatus of the workpiece according to the present invention has been described, but the present invention is not limited thereto, and various modifications are made within the scope of the claims and the detailed description of the invention and the accompanying drawings. It is possible to implement, which also belongs to the scope of the present invention.

The present invention configured as described above allows grinding both sides of the workpiece at the same time by using a grindstone in the process of moving the workpiece seated on the conveyor belt in one direction, thereby preventing both sides of the workpiece to be uniformly ground and moving the workpiece. It is equipped with a bearing that has the effect of performing safe and precise polishing when polishing the workpiece.

In addition, all processes to perform the polishing operation from the supply of the workpiece is automated to prevent the occurrence of safety accidents of the worker.

In addition, since the polishing of both sides of the workpiece is performed three times, more precise polishing is possible.

In addition, by separately collecting the dust generated during the polishing operation to be discharged to the outside there is an effect that can prevent the surrounding environment, such as the workplace contamination.
