(definition: the axial direction of the grinding wheel 3 is the front-back direction, the axial direction of the crystal bar 6 is the left-right direction); (4) the positioning seat 2 is detached from the base 1 and separated from the grinding wheel 3; because the line to be processed extends along the extending direction of the crystal bar 6 (i.e. the line to be processed extends along the left-right direction), the line to be processed is located at the top end of the side surface of the crystal bar 6, and the line to be processed is located on the moving path of the grinding wheel 3 which vertically descends (please refer to the above reasoning); when the grinding wheel 3 vertically descends, the grinding wheel 3 can be contacted with a line to be processed on the crystal bar 6 and can be ground, the horizontal table top 7 is moved left and right, so that the grinding wheel 3 can grind a strip-shaped groove extending towards the extending direction of the crystal bar 6 on the crystal bar 6 along the line to be processed (the line to be processed extends along the left and right directions), and the positioning process is very simple.
Wherein, the positioning seat 2 is detachably arranged on the base 1; in particular, in one embodiment, the positioning socket 2 is supported on a predetermined top area of the base 1; specifically, in another embodiment, the positioning seat 2 is fixed on a predetermined position of the base 1 by a fastener; specifically, in one embodiment, the fasteners are screws.
Optionally, in one embodiment, the horizontal table 7 has an adsorber thereon for adsorbing the base 1. Specifically, in one embodiment, the adsorber is a suction orifice.
Optionally, in one embodiment, the slot 231 is located directly above the U-shaped cylindrical slot 15.
Optionally, in one embodiment, the edge of the grinding wheel 3 is V-shaped in the axial section of the grinding wheel 3. Thus, the grinding wheel 3 can grind a V-shaped groove.
Optionally, in one embodiment, the base 1 and the positioning seat 2 are both made of steel and are made of a single piece.
In the present application, the side surface of the ingot 6: refers to the cylindrical arc surface between the two end surfaces of the crystal bar 6.

Thus, the first abutting surface 211 abuts against the top surface 12, and the second abutting surface 221 abuts against the left side surface 13, so that the positioning seat 2 can be arranged on the base 1, which is very convenient; in addition, the top surface 12 can distribute the pressure exerted by the first contact surface 211 on the base 1, and similarly, the left side surface 13 can distribute the pressure exerted by the second contact surface 221 on the base 1; in addition, because the axis of the U-shaped cylindrical groove 15 is parallel to the top surface 12 and the left side surface 13, when the first abutting surface 211 abuts against the top surface 12 and the second abutting surface 221 abuts against the left side surface 13, the positioning seat 2 slides along the top surface 12 and the left side surface 13 relative to the base 1, so that the positioning seat 2 can slide along the extending direction of the U-shaped cylindrical groove 15 to adjust the position thereof.
Further, referring to fig. 1 to 3, as an embodiment of the crystal bar positioning device of the present invention, a right side 14 of the base 1 is a plane, and the right side 14 is parallel to the left side 13. Thus, the left side surface 13 and the right side surface 14 can be easily processed. Specifically, in one embodiment, the left side 13 and the right side 14 are perpendicular to the top surface 12, and the left side 13 and the right side 14 are equidistant from the axis of the U-shaped cylindrical slot 15. Thus, when the first abutting surface 211 abuts against the top surface 12, the second abutting surface 221 may selectively abut against the left side surface 13, and the second abutting surface 221 may selectively abut against the right side surface 14.
Further, referring to fig. 1 to 3, as an embodiment of the crystal bar positioning device of the present invention, the bottom surface 11 and the top surface 12 are disposed in parallel. Thus, when the bottom surface 11 is supported on the horizontal table surface 7, the top surface 12 is horizontally disposed, and when the positioning seat 2 abuts against the top surface 12 through the first abutting surface 211, the positioning seat 2 can be stably supported on the top surface 12.
Further, referring to fig. 1 to 3, as a specific embodiment of the crystal bar positioning device of the present invention, the positioning seat 2 includes a first plate 21, a second plate 22, and a positioning portion 23; the first abutting surface 211 is a side surface of the first board body 21, and the second abutting surface 221 is a side surface of the second board body 22; the catching groove 231 is provided on the positioning portion 23, and the positioning portion 23 is provided on the first plate body 21. Thus, the first plate body 21 uses its own plane surface as the first abutting surface 211, which reduces the manufacturing workload; the second plate 22 uses its own plane surface as the second abutting surface 221, so as to reduce the manufacturing workload.
Further, referring to fig. 1 to 3, as an embodiment of the crystal bar positioning device of the present invention, the positioning portion 23 is close to the edge of the first plate 21. Thus, when the slot 231 of the positioning portion 23 is engaged with the grinding wheel 3, the first plate 21 is not easily knocked against the grinding wheel 3 or the peripheral devices of the grinding wheel 3.
Further, referring to fig. 1 to 3, as an embodiment of the crystal bar positioning device of the present invention, the positioning portion 23 and the first abutting surface 211 are respectively located at two opposite sides of the first plate 21. Thus, when the engaging groove 231 of the positioning portion 23 is engaged with the grinding wheel 3, the contact between the first abutting surface 211 and the top surface 12 is not easily disturbed.
Further, referring to fig. 1 to 3, as a specific embodiment of the crystal bar positioning device of the present invention, a fastening mechanism 5 for fixing the grinding wheel 3 clamped in the clamping groove 231 is disposed on the positioning portion 23. Thus, the grinding wheel 3 clamped in the clamping groove 231 can be fixed in the clamping groove 231 through the fastening mechanism 5, and the change of the relative position between the positioning part 23 and the grinding wheel 3 in the mutual installation/disassembly process of the positioning seat 2 and the base 1 is reduced.
Further, referring to fig. 1 to 3, as a specific embodiment of the crystal bar positioning device provided by the present invention, the fastening mechanism 5 includes a threaded hole 51 provided on the positioning portion 23 and communicating with the slot 231, and a screw 52 screwed with the threaded hole 51 to extend into the slot 231 and abut the grinding wheel 3 on the left/right plane inner walls 2311, 2312. Thus, the screw 52 penetrates through the threaded hole 51 and extends into the clamping groove 231 to enable the grinding wheel 3 to be abutted to the inner wall 2312 of the seat plane/the right plane, so that the grinding wheel 3 can be positioned very conveniently.
Further, referring to fig. 1 to 3, as a specific embodiment of the crystal bar positioning device provided by the present invention, the number of the screws 52 and the threaded holes 51 is plural, and the plural screws 52 and the plural threaded holes 51 correspond to each other one to one.
