[0024] Different circular crystal sheets 6 are stacked and bonded in the thickness direction to form a circular crystal sheet group, and the reserved inclined surfaces on the side of each circular crystal sheet in the circular crystal sheet group correspond to each other, that is, the circular crystal sheet group is columnar and has an inclined surface on one side; two glass protection sheets 3 are clamped and fixed at both ends of the above circular crystal sheet group, and have the same shape and size as the above circular crystal sheet 6 in the circumferential direction, and the inclined surface on one side of the glass protection sheet 6 corresponds to the inclined surface on the glass protection sheet 3, so as to form a cylindrical workpiece to be processed with an inclined surface on one side of the above circular crystal sheet group. The different components constituting the workpiece to be processed are bonded together by a viscous medium, and then separated after groove marking.

[0025] The workpiece to be processed is placed on the bottom surface 51 of the "L"-shaped right-angle fixture 5, and the right triangle positioning block 2 is also located on the bottom surface 51 of the "L"-shaped right-angle fixture 5, and the waist surface of the upper inclined surface fits the inclined surface on the workpiece to be processed, pushing the right triangle positioning block 2, so that the outer cylindrical surface of the workpiece to be processed is in contact with the bottom surface 51 and the vertical surface 52 of the "L"-shaped right-angle fixture 5 at the same time, so as to achieve the fixed positioning of the workpiece to be processed in the radial direction. The rectangular standard block 4 is located on the bottom surface 51 of the "L"-shaped right-angle fixture 5, and is in full contact with the two mutually perpendicular surfaces (bottom surface 51 and vertical surface 52) on the "L"-shaped right-angle fixture 5 through two adjacent vertical surfaces thereon; and the rectangular standard block 4 is also bonded and fixed to the glass protection sheet 3 at the rear end of the workpiece to be processed through its front end surface.

In other embodiments of the utility model, there are multiple right triangle positioning blocks 2, and their waist faces have different inclination angles, that is, the waist faces of different right triangle positioning blocks 2 have different angles with the two straight faces, so that the inclined surface and the bottom surface 51 on the workpiece to be processed that are positioned by different right triangle positioning blocks 2 have different angles, and then the positional relationship between the outer circular top and the inclined surface of the workpiece to be processed when it is positioned by the rectangular standard block 4 is different, so as to meet the requirements of obtaining groove marking positions of different orientations of the workpiece to be processed.

[0027] In the utility model, the surfaces of the straight triangle positioning block are flat, and the workpiece to be processed can be accurately positioned to ensure the processing quality.

The two adjacent vertical surfaces of the rectangular standard block and the two mutually perpendicular surfaces of the "L"-shaped right-angle tooling are completely contacted, and the adhesive is applied to the end of the workpiece to be processed, and the rectangular standard block slides until it is completely in contact with the glue-coated end, and the bonding is completed after a while. After the workpiece to be processed and the rectangular standard block are firmly bonded, the grooving process is completed by fixing the rectangular standard block on the grooving equipment, and the required groove mark 1 for the identification axis direction is correctly processed.
