The mounting columns 4 are slidably installed in a movable groove 5 provided in the base 1, the bottom of the mounting columns 4 is fixedly connected with a movable block 9, and an adjustment mechanism acting on the movable block 9 is provided on the base 1, and a mounting plate 11 is fixedly connected to the upper side of the side wall of the mounting column 4, and a guide groove is provided on the side wall of the mounting plate 11 14, a guide block 13 is slidably installed in the guide groove 14, a mounting piece 18 is fixedly connected to the side wall of the guide block 13, a slide groove 19 is provided inside the mounting piece 18, a slider 16 is slidably installed in the slide groove 19, a spring 15 is fixedly connected between the slider 16 and the inner wall of the slide groove 19, the spring 15 is made of carbon steel, the other end of the slider 16 is fixedly connected to a connecting rod 17, the other end of the connecting rod 17 slides through the inner wall of the slide groove 19 and extends to the outside of the mounting piece 18, the end of the connecting rod 17 is fixedly connected to a clamping plate 6, and the end surfaces of the two clamping plates 6 close to each other are both set as arc surface structures.

[0021] Among them, the adjustment mechanism includes a motor 7, a fixed plate 8 and a double-headed screw 10. A fixed plate 8 is provided on the side of the two movable blocks 9 away from each other. The fixed plate 8 is fixedly connected to the base 1. A double-headed screw 10 is rotatably connected between the two fixed plates 8. The double-headed screw 10 is made of cemented carbide. The double-headed screw 10 runs through the two movable blocks 9. The two movable blocks 9 are threadedly sleeved at both ends of the double-headed screw 10. The motor 7 is fixedly mounted on the side wall of a fixed plate 8, and the output shaft of the motor 7 is fixedly connected to the shaft end of the double-headed screw 10.

[0022] When in use, the starting motor 7 drives the double-headed screw 10 to rotate, and the movable block 9 is restricted by the mounting column 4 and cannot rotate. When the double-headed screw 10 rotates, the two movable blocks 9 will move closer to or farther away from each other.

[0023] The upper surface of the processing table 3 is frosted.

[0024] Such an arrangement can increase the friction between the processing table 3 and the ceramic blank.

[0025] Wherein, a rubber layer is arranged on the clamping end surface of the clamping plate 6 .

[0026] The rubber layer can be provided to prevent the clamping plate 6 from damaging the outer surface of the ceramic blank, and at the same time, the friction between the clamping plate 6 and the ceramic blank can be increased.

[0027] The utility model provides a positioning device for ceramic processing, and the specific working principle is as follows:

[0028] When in use, the ceramic blank is placed on the processing table 3, and the two movable blocks 9 are controlled to approach each other through the adjustment mechanism, thereby driving the two mounting columns 4 to approach each other, so that the two clamping plates 6 clamp the side walls of the ceramic blank to position and fix the ceramic blank. Through the combination of the clamping plates 6, the connecting rods 17, the sliders 16 and the springs 15, when the clamping plates 6 clamp the ceramic blank, the springs 15 will be compressed, so that the clamping plates 6 add an elastic force to the ceramic blank to prevent the clamping plates 6 from crushing the ceramic blank. At this time, the staff can draw a pattern on the outer surface of the ceramic blank. When the position of the clamping plates 6 affects the pattern drawing, the two clamping plates 6 can be held to make it Move in the direction away from the ceramic blank, at this time the spring 15 will be compressed, and then the clamping plate 6 is moved upward, and the clamping plate 6 can move freely up and down under the sliding fit of the guide block 13 and the guide groove 14. When the clamping plate 6 moves to the position on the ceramic blank where the painting is completed and the pigment is dry, the clamping plate 6 is released, and under the action of the spring 15 restoring the deformation, the two clamping plates 6 will clamp the ceramic blank again. At this time, the staff can draw patterns on the part of the ceramic blank that was previously covered by the clamping plate 6. Since the force is mutual, the guide block 13 will also be pressed against the side wall of the guide groove 14, and the guide block 13 will not move up and down without interference from external forces.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
