[0019] (II) In this adjustable angle grinding wheel device, the height of the placement plate of the placement mechanism can be adjusted by the threaded engagement of the threaded rod and the nut.

[0030] A mounting bracket 21 is fixedly installed on the outer wall of the base plate 1. A mounting frame 28 is fixedly installed on the inner side of the mounting bracket 21. A servo motor 29 is fixedly installed on the outer wall of the mounting frame 28. The output end of the servo motor 29 extends through the outer wall of the mounting frame 28 to the inner side of the mounting frame 28. A rotating rod 24 is fixedly installed on the outer wall of the output end of the servo motor 29. The outer wall of the rotating rod 24 is fixedly connected to the inner side of the control block 210. A connecting plate 211 is fixedly installed on the outer wall of the control block 210. The outer wall of the connecting plate 211 is fixedly connected to the outer wall of the grinder 22. The outer wall of the rotating rod 24 rotates through the inner side of the mounting frame 28 to the outer side of the mounting frame 28. The outer wall of the rotating rod 24 is fixedly connected to the inner side of the gear 27. The outer wall of the fixed frame 21 is fixedly provided with a limit frame 213 extending to the inner side of the fixed frame 21. The inner side of the limit frame 213 is slidably provided with a pressing block 214. The bottom surface of the pressing block 214 is fixedly provided with a trapezoidal block 212. The outer wall of the trapezoidal block 212 meshes with the tooth surface of the gear 27. The top surface of the fixed frame 21 is fixedly provided with a support frame 23. The inner side of the support frame 23 is fixedly provided with a spring 26 and a damper 25. The bottom surfaces of the spring 26 and the damper 25 are both fixedly connected to the top surface of the pressing block 214. The initial state of the spring 26 is the extended state.

[0031] The placement mechanism 3 includes a placement plate 32. The top surface of the base plate 1 is slidably connected to the bottom surface of the movable plate 31. The placement plate 32 is located above the movable plate 31. A fixing plate 35 is fixedly installed on the outer wall of the movable plate 31. A threaded rod 36 is fixedly installed on the top surface of the fixing plate 35. A fixing block 37 is fixedly installed on the outer wall of the placement plate 32. The top surface of the threaded rod 36 extends through the bottom surface of the fixing block 37 and above the fixing block 37. A nut 38 is rotatably installed on the top surface of the fixing block 37 through a bearing seat. The inner side of the nut 38 is threadedly connected to the outer wall of the threaded rod 36. A slide rail 39 is fixedly installed on the top surface of the base plate 1. The outer wall of the slide rail 39 is slidably connected to the inner side of the movable plate 31. A control frame 310 is fixedly installed on the outer wall of the movable plate 31. Multiple positioning rods 33 are fixedly installed on the outer wall of the movable plate 31. Multiple positioning sleeves 34 are fixedly installed on the outer wall of the placement plate 32. The outer walls of the multiple positioning rods 33 are slidably connected to the inner sides of the multiple positioning sleeves 34 respectively.

[0032] In use, the placement plate 32 is used to support the workpiece to be processed. Its height can be adjusted by the cooperation between the threaded rod 36 and the nut 38. When the nut 38 is rotated, the rotation of the nut 38 will be converted into the up and down movement of the placement plate 32 along the axial direction of the threaded rod 36. At the same time, the sliding cooperation between the positioning rod 33 and the positioning sleeve 34 ensures the stability of the lifting process of the placement plate 32.

[0033] When the angle of the grinding machine 22 needs to be adjusted, the servo motor 29 starts, and its output drives the rotating rod 24 to rotate. The control block 210, which is fixedly connected to the rotating rod 24, rotates synchronously. The grinding machine 22, which is connected to the control block 210 through the connecting plate 211, will change its angle around the axis of the rotating rod 24, thereby realizing the adjustment of the grinding angle. During this process, when the rotating rod 24 rotates, it will drive the gear 27 fixed on its outer wall to rotate together. At the same time, the pressing block 214 on the inner side of the fixed frame 21, under the action of the spring 26 and the damper 25 on the support frame 23, always maintains engagement with the tooth surface of the gear 27. Thus, after the angle adjustment is completed, the pressing force of the pressing block 214 on the gear 27 can be used to restrict its autonomous rotation, ensuring that the angle of the grinding machine 22 is stable during the grinding process.

[0034] After the adjustment is completed, turn on the grinder 22. At this time, manually move the control frame 310 horizontally back and forth so that the workpiece above the placement plate 32 can be ground.
