Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] For example, see Figures 1 to 4The utility model provides a grinding device for a CNC lathe, comprising a base plate 1 and a cylindrical workpiece 14, the upper surface of the base plate 1 is fixedly connected to a support platform 10, the lower surface of the support platform 10 is fixedly connected to a fixed plate 12, the inner wall of the fixed plate 12 is rotatably connected to a fixed ring 15, and the fixed ring 15 is used to fix the cylindrical workpiece 14.

[0028] The fixing component includes a limit frame 20 fixedly connected to the surface of the fixing ring 15, a motor 27 is arranged on the surface of the limit frame 20, a threaded rod 26 is fixedly connected to the surface of the motor 27, two sections of oppositely arranged threaded grooves are opened on the surface of the threaded rod 26, and two symmetrically arranged moving rods 21 are threadedly connected to the surface of the threaded rod 26, and spring fixing components 22 are arranged at the ends of the two moving rods 21.

[0029] The auxiliary components include a support plate 23 fixedly connected to the surface of the fixed plate 12, a motor 24 is arranged on the surface of the support plate 23, the output shaft of the motor 24 is fixedly connected to the gear 2, and the surface of the fixed ring 15 is fixedly connected to the gear ring 13 meshing with the gear 2.

[0030] A hydraulic component 11 is provided on the upper surface of the support platform 10, and a motor box 17 is fixedly installed on the output end of the hydraulic component 11. Motor three is provided in the motor box 17, and the output shaft of motor three is fixedly connected with threaded rod two 18, and the end of threaded rod two 18 is threadedly connected with a grinding disc 19, and a collection box 16 is provided on the upper surface of the base plate 1.

[0031] More specifically, when this embodiment is used, Figure 3 and Figure 4 As shown, the cylindrical workpiece 14 to be polished is placed into the circular opening on the surface of the fixing ring 15, and then the motor 27 is turned on to drive the threaded rod 26 to start rotating. Since the surface of the threaded rod 26 is provided with two oppositely arranged thread grooves, the rotation of the threaded rod 26 will cause the two moving rods 21 to move towards each other. With the movement of the two moving rods 21, the cylindrical workpiece 14 can be fixed under the action of the two spring fixing assemblies 22.

[0032] Then, if Figure 1 and Figure 2 As shown, the hydraulic assembly 11 is controlled to drive the grinding disc 19 to descend to the grinding position, and then the motor three in the motor box 17 is turned on to make the grinding disc 19 rotate at high speed. Under the action of the grinding disc 19, the cylindrical workpiece 14 fixed below can be ground.

[0033] It is worth noting that, at the same time, the motor 24 is turned on to drive the gear 2 to rotate.

[0034] Embodiment 2, based on the above embodiment:

[0035] Further, the cleaning component in the first embodiment is disclosed, and the cleaning component includes a piston cylinder 7 fixedly mounted on the upper surface of the support platform 10, the inner wall of the piston cylinder 7 is slidably connected with a piston plate, the lower surface of the piston plate is fixedly connected with a piston rod 6, the end of the piston rod 6 is fixedly connected with a hinge block 5, and the surface of the hinge block 5 is hinged with a hinge plate 4;

[0039] More specifically, when this embodiment is used, Figure 1 and Figure 3 As shown, when the motor 24 is turned on and the gear 2 is driven to rotate, the movable column 3 will also make a circular motion synchronously with the gear 2. During this process, under the hinged action of the hinged plate 4, the piston rod 6 will drive the piston plate to make a piston motion in the piston cylinder 7, so that the clean water in the water tank 8 can be first sucked into the piston cylinder 7 through the liquid inlet pipe 25, and then sprayed onto the surface of the cylindrical workpiece 14 being ground after being atomized by the atomizing nozzle at the end of the liquid outlet pipe 9, thereby avoiding the problem that the grinding powder or debris on the cylindrical workpiece 14 cannot be cleaned in time during the grinding operation, and the debris and grinding powder will affect the subsequent grinding of the cylindrical workpiece 14.

[0040] It is worth noting that the water mist sprayed from the atomizing nozzle can also cool the surface of the cylindrical workpiece 14, thereby preventing the high temperature on the surface of the cylindrical workpiece 14 from causing damage to the workpiece body during the grinding operation. It is more practical and worthy of promotion and use.
