The spindle structure 4 includes: headstock 41, main shaft 42, power device 43. The bottom of the main spindle box 41 is fixedly connected with the nut seat 23 and the slide block 32. The servo motor 22 transmits the rotation power through the screw rod 21 and converts the rotation power into the linear motion power through the nut seat 23, and then the linear motion power is connected with the spindle box 41 through the nut seat 23, so that the servo motor 22 can drive the spindle box 41 to move forwards or backwards through the power, and the forward or backward amount of the spindle box 41 can be accurately controlled by controlling the rotation amount of the servo motor 22. And the main shaft 42 is arranged on the main shaft box 41, so that when the servo motor 22 controls the main shaft box 41 to move forwards or backwards, the feeding or resetting movement of the main shaft 42 arranged on the main shaft box 41 can be controlled, the feeding amount of the main shaft 42 is accurately controlled through the servo motor 22, and the problem of overlarge precision error existing in manual feeding is solved. Compared with the traditional mode of connecting the spindle box 41 and the sliding block 32 with the base 1 in a dovetail groove mode, the friction of the spindle box 41 in sliding fit with the base 1 can be reduced, the mode of connecting the spindle box 41 and the sliding block 32 with the base 1 in a guide rail 31 is adopted to enable the spindle box 41 to be in sliding fit with the base 1, the influence on feeding precision due to overlarge friction force between the spindle box 41 and the base 1 in the feeding process of the spindle 42 can be avoided, and therefore the feeding precision of the spherical milling machine is further improved. The fixture tool for clamping the workpiece 6 to be machined is further arranged at one end of the main shaft 42, and the workpiece 6 to be machined can be firmly fixed at the end of the main shaft 42 through the fixture tool, so that machining is facilitated.

In summary, the servo motor 22 is used to drive the screw rod 21 to rotate, the nut seat 23 is used to convert the rotational motion into the linear motion, and then the spindle structure 4 is connected to the nut seat 23, so that the servo motor 22 can drive the spindle structure 4 to perform the feeding or resetting motion, and the amount of motion of the feeding or resetting motion of the spindle structure 4 can be accurately controlled by controlling the rotation amount of the servo motor 22. And in order to avoid the feeding process of the spindle structure 4 being hindered by the friction resistance generated by the sliding fit of the spindle structure 4 with the base 1 in the feeding process, the base 1 supports the spindle structure 4 through the slider guide rail structure 3, and compared with the conventional sliding connection between the spindle structure 4 and the base 1 by adopting a dovetail groove structure, the slider guide rail structure 3 has lower friction force (the guide rail 31 adopts a cylindrical structure with a smooth surface), so that the feeding amount inaccuracy caused by the influence of the friction force when the spindle structure 4 is fed can be avoided. And because the slide block guide rail structure 3 has lower friction, the abrasion between the main shaft structure 4 and the base 1 can be reduced when the spherical milling and grinding machine works, and the service life of the spherical milling and grinding machine is prolonged. Therefore, the spherical milling and grinding machine in the embodiment has the advantages of accurately controlling the feeding amount, reducing the friction of the equipment during operation and prolonging the service life of the equipment.

Compared with the two guide rails 31 arranged on one side of the screw rod 21, the two guide rails 31 are respectively arranged on the two sides of the screw rod 21, so that the matching of the main shaft 42 mechanism and the base 1 is more stable, and the influence on the machining precision caused by the vibration of the main shaft structure 4 during operation when the guide rails 31 are arranged on one side is avoided.
In order to allow the servo motor 22 to intuitively adjust the feeding amount of the spindle 42, further, the axis of the spindle 42 is parallel to the axis of the screw 21. The main shaft 42 and the screw rod 21 are arranged in parallel, so that when the servo motor 22 controls the screw rod 21 to rotate and the nut seat 23 moves linearly, the feeding amount of the nut seat 23 is the feeding amount of the main shaft 42, and the feeding amount control difficulty of the servo motor 22 on the main shaft 42 can be simplified by arranging the main shaft 42 and the screw rod 21 in parallel, so that the feeding amount of the main shaft 42 can be controlled simply and conveniently by the servo motor 22.
