[0002] Generally, various jewelery machines are widely used as a device for polishing natural or artificial jewelery including crystal, sapphire, cubic, and diamond, and this applicant is also referred to as " (Patent Registration No. 0940278), which is registered as a patented date.

A typical construction of the above-described conventional jewelery machine includes a base frame; A grinding wheel installed at an upper end of the base frame so as to be rotatable in a state of being connected to a motor through a rotating shaft, and having a predetermined shape; A jeweler holder having a trapezoid-shaped binding portion on one side and being glued and fixed in a state that the jewel for pore is gripped; A holder fixing bar and holder fixing means fixedly positioned at the upper end of the polishing wheel through a support bracket and fixedly coupled to the gemstone holder so as to correspond to the polishing wheel; A holder fixed to one end of the holder fixing bar and rotatable in a downward direction according to driving of the motor for punching a crown, a pavilion, and a girdle portion of a pore portion of the jewel, A tilt adjusting means; The holder is rotatably installed at the other end of the holder fixing bar and is rotated by motor driving to form a pore surface in a crown, pavilion, or girdle portion of the pore portion of the jewel, A holder spindle rotating unit for rotating each spindle of the holder; Holder lifting means for lifting and lowering the holder fixing bar according to an initial setting and punching work for punching the gemstone adhered and fixed to the gemstone holder; And a control unit for controlling motor driving connected to the grinding wheel, the holder elevating means, the holder inclination adjusting means, and the holder spindle rotating unit, and a control unit for controlling the motor driving connected to the grinding wheel, And the jewel holder is slid left and right from the polishing wheel by the left and right operation plate conveying means installed at both ends of the base frame, And left and right operation plates for guiding the jewels into a predetermined shape are fastened and fixed to the lower ends of support brackets formed at both ends of the holder fixing bar in a state of inserting the entire grinding wheel.

In such a conventional jewelery machine, only a planar polishing process is performed in which a plurality of facets are formed around the jewel by pressing a rotating abrasive surface with a constant force. In the case of a three-dimensional curved surface abrading process, It is very difficult and uncomfortable to grind the work using a conventional grinding machine. In addition, it is difficult to realize a three-dimensional curved surface grinding work as a conventional grinding machine, First, the outer shape of the jewelery is firstly polished using a jeweler's finishing machine, and then the first-time polished jeweler is manually processed by the skilled worker through the jeweler's finishing machine to perform a three- It is very troublesome and inconvenient to perform a three-dimensional surface polishing operation on the jewelry.

In addition, as described above, since the three-dimensional curved surface polishing work on jewelries is very troublesome and inconvenient, not only the working time and the working process are long due to the whole polishing work, but also the economical efficiency is decreased, There is a limited problem in purchasing expensive jewelery such as the above-mentioned expensive jewelery such as the above-mentioned expensive only because it is expensive, and it is absolutely urgent to supply a low cost jewelery product by mass production to a lot of people. I will.

In addition, in the case of a glass installed in the front window portion of a mobile phone, a tablet PC, and various HPCs, as in the case of a gem stitching apparatus for polishing jewelery in advance, Only the flat polishing process is performed on the glass by pressing with force, and the curved surface polishing of the three-dimensional shape with respect to one side or both sides of the glass is performed by a conventional glass polishing apparatus manufactured in conformity with the above- It is very difficult and uncomfortable to simultaneously perform a three-dimensional curved surface polishing operation. In order to perform a three-dimensional curved surface polishing operation on the glass, After the primary polishing operation is performed, the primary polishing operation is performed through the glass polishing apparatus The working time and the working process for performing the surface polishing of the three-dimensional shape on the glass, such as the manual polishing of the surface or the both surfaces manually by the skilled operator, In addition to the deteriorating economy, the selling price of the glass is also high, which is applied to the selling price of a mobile phone, a tablet PC and various HPC.

In addition, as described above, since the operator manually performs the polishing operation of the glass or the workpiece while pressing it with his hand, not only the precision and the production amount of the product are significantly lowered, but also the surface pressure applied to the workpiece by the operator's hand is uniform The surface of the workpiece is uneven, and thus the gloss of the various workpieces produced is not uniform, and the flatness and the surface roughness of the surface of each workpiece are also uneven.

In addition, when the operator performs the polishing work while pressing with the hand as described above, the arm is painfully retained due to the maintenance of excessive force during the long time work, and the uniform force can not be applied. In addition, There is a problem that the surface of the workpiece is scratched in reverse while being shaken.

Therefore, it is absolutely urgent to develop a curved surface polishing machine equipped with a multi-axis surface pressure adjusting device as a method for solving the conventional problems as described above.

In order to solve the above-mentioned problems, the present invention has been developed to solve the above-mentioned problems of the prior art, and it is an object of the present invention to provide a jewelery such as glass, crystal, sapphire, cubic, diamond and the like installed in a screen window part of a mobile phone, Or a three-dimensional curved surface shape, a plurality of polishing optical tips corresponding to a plurality of workpieces, such as glass and jewelery, for polishing the workpiece by motor driving, and spline shafts individually connected thereto and a motor Are connected to each other through a timing belt, and a surface pressure adjusting device is axially coupled to the upper end of each of the spline shafts so as to adjust the surface pressure of the grinding light tip with respect to the workpiece so that the grinding light tip presses the workpiece with uniform pressure, As a result of the polishing process, It is possible to polish a plurality of workpieces by a three-dimensional curved surface polishing machine having a CNC type multi-axis automation structure in one operation at the same time, thereby shortening the working time accordingly, and at the same time, The object of the present invention is to improve the working speed and the working efficiency of the workpiece as well as the precision and the production amount of the product.

In the case of the present invention, since the surface pressure acting on the workpiece from the grinding light tip uniformly acts through the multi-axis surface pressure adjusting device among the three-dimensional curved surface grinding machine constructed as described above, the surface gloss of each workpiece becomes uniform, The flatness and the surface roughness of the surface can be improved and also the occurrence of the reverse scratch due to the polishing work performed while the user is pressing with the hand can be prevented.
