[0021] The first linear module 201 is fixedly connected to the base 1, and the cylindrical gear 203 is rotatably connected to the base 1. The first linear module 201 is used to drive the rack 202 to slide. During the sliding process of the rack 202, it can drive the cylindrical gear 203 to rotate, and the rack 202 is meshed with the cylindrical gear 203.

[0022] The second linear module 302 is fixedly connected to the clamping slide 301, the hollow rotating platform 303 is fixedly connected to the movable table of the second linear module 302, and the chuck 304 is detachably connected to the rotating table of the hollow rotating platform 303. A suitable chuck 304 can be installed on the rotating table of the hollow rotating platform 303 according to the diameter of the sphere to be processed, and the end of the chuck 304 is provided with a spherical surface.

[0023] The sphere lifting carrier 5 includes a base 501, an electric cylinder 502, a lifting seat 503, a lifting cylinder 504 and a four-jaw chuck 505. The base 501 is fixedly connected to the base 1, the electric cylinder 502 is fixedly connected to the base 501, the lifting seat 503 is fixedly connected to the lifting platform of the electric cylinder 502, the electric cylinder 502 is used to drive the lifting seat 503 to slide and lift, the sliding platform of the lifting cylinder 504 is fixedly connected to the lifting seat 503, the shell of the lifting cylinder 504 is fixedly connected to the shell of the four-jaw chuck 505, and the four-jaw chuck 505 is used to position and place the sphere.

[0024] The four jaws of the four-jaw chuck 505 are each provided with an inclined surface on one side close to the axis.

[0025] A strip groove is formed on the base 1 just below each clamping slide 301 , and the cam follower 305 extends into the base 1 through the strip groove.

[0026] The working principle of the present invention is: before use, the present invention first selects a suitable chuck 304 according to the diameter of the sphere to be processed and fixes it on the rotating table of the hollow rotating platform 303, then adjusts the clamping position of the four-jaw chuck 505 to adapt to the placement of spheres of different diameters (ensuring that the center positions of spheres of different diameters are consistent after placement), and then the second linear module 302 drives the hollow rotating platform 302 to rise and fall to the appropriate position, so that the chuck 304 can completely fit with the spherical surface of the sphere when clamping.

[0027] When the present invention is in use, the sphere to be processed is first placed on the clamping jaws of the four-jaw chuck 505, and then the electric cylinder 502 drives the lifting seat 503 to rise to a suitable height, and then the piston rod of the lifting cylinder 504 is extended, and the four-jaw chuck 505 rises to the clamping position (to ensure that the highest point positions of spheres with different diameters remain consistent after clamping), and then the first linear module 201 drives the rack 202 to slide, and under the sliding action of the rack 202, the cylindrical gear 203 rotates, and under the action of the first arc groove 2031, the two first sliding clamping mechanisms 3 will move closer to each other at the same time, and under the action of the second arc groove 2032, the two second sliding clamping mechanisms 3 will move away from each other at the first sliding clamping mechanism 3, the chucks 304 of the two first sliding clamping mechanisms 3 will clamp the sphere, and then the piston rod of the lifting cylinder 504 will retract. In return, one side of the sphere can be cut by an external laser cutter. After one side is processed, the hollow rotating platform 303 of the two first sliding clamping mechanisms 3 will drive the chuck 304 to rotate and change the surface together with the sphere. After the processing of the four sides of the sphere is completed, the piston rod of the lifting cylinder 504 is extended again, and the four-jaw chuck 505 supports the sphere. Then the first linear module 201 drives the rack 202 to slide in the opposite direction, thereby driving the cylindrical gear 203 to reverse, so that the two first sliding clamping mechanisms 3 move away from each other, and the two second sliding clamping mechanisms 4 approach each other. At this time, the sphere is clamped by the chuck 304 of the second sliding clamping mechanism 3, and the other two sides of the sphere are reversed by the second sliding clamping mechanism 3 to achieve the reversal processing of the 6 sides of the sphere, thereby improving the production efficiency and processing quality of the sphere.
