[0023] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0024] like Figure 1 As shown, the utility model describes a cam lifting device for multi-station processing, comprising a supporting positioning module 1, a rotating processing module 2 rotatably arranged in the supporting positioning module 1, and a cam lifting mechanism 3 arranged below the supporting positioning module 1. The rotating processing module 2 comprises a rotating shaft 21, a rotating driving member that drives the rotating shaft 21 to rotate, and a fixed material turntable 22 that rotates around a rotation center under the drive of the rotating shaft 21. The fixed material turntable 22 is evenly arranged with a plurality of storage stations 23 for positioning workpieces along the circumference, and a lifting component 4 is provided corresponding to each storage station 23. The lifting component 4 lifts the workpiece to a processing height in cooperation with the cam lifting mechanism 3.

[0025] like Figure 2 As shown, the supporting and positioning module 1 includes a supporting base plate 11 and a supporting plate 12 fixed on the supporting base plate 11 . The rotating shaft 21 is rotatably connected to the supporting plate 12 via a first linear bearing 13 . The material setting turntable 22 is transmission-connected to the rotating shaft 21 .

[0026] In this embodiment, Figure 3 The storage station 23 is a contoured through hole 24 set on the material fixing turntable 22. The center of the contoured through hole 24 is along the axial direction. The inner periphery of the contoured through hole 24 is provided with a supporting platform 241 for supporting and holding the workpiece. The workpiece is located in the contoured through hole 24. Each storage station 23 is used to carry and position a workpiece.

[0027] like Figure 4The lifting assembly 4 includes a second linear bearing 42 fixed under the material fixing turntable 22, and a guide part 41 that passes through the second linear bearing 42 and lifts the workpiece. The guide part 41 is slidably connected to the material fixing turntable 22 through the contoured through hole 24 in the vertical direction. The second linear bearing 42 is used to limit the displacement of the guide part 41 in the vertical direction. A lifting roller 414 is provided at one end of the guide part 41 that cooperates with the cam lifting mechanism 3.

[0028] Specifically, such as Figure 6 The guide portion 41 includes a lifting rod 411 along the vertical direction and a connecting rod 412 along the radial direction. The lifting rod 411 and the connecting rod 412 are fixedly connected by screws, and the lifting roller 414 is rotatably connected to the end of the connecting rod 412 that cooperates with the cam lifting mechanism 3.

[0029] Furthermore, the end of the lifting rod 411 for lifting the workpiece is provided with a lifting block 413 that contacts the workpiece and lifts the workpiece. The end of the lifting rod 411 and the lifting block 413 are connected by a bearing. When the workpiece rotates during processing, the bearing can reduce the friction caused by relative rotation.

[0030] like Figure 5 The cam lift mechanism 3 includes a cylindrical guide plate 31 coaxially arranged with the material-fixing turntable 22 and supported by a fixed frame. An annular track 32 is provided around the circumference of the guide plate 31; the lift roller 414 is mounted within the annular track 32. The annular track 32 includes a cam track arranged circumferentially around the guide plate 31. The cam track includes an ascending section 321 and a descending section 322. Driven by the rotation of the rotating shaft 21, the material-fixing turntable 22 rotates, driving the lift roller 414 to roll within the annular track 32. The lift roller 414 moves along the cam track of the annular track 32, driving the lift rod 411 to lift and lower the workpiece.

[0031] Furthermore, the fixed frame includes a lower base plate 5, and the rotating shaft 21 is rotatably connected to the fixed frame through a third linear bearing 51, that is, the rotating shaft 21 has multiple support points along the axial direction, so that the rotating shaft 21 drives the fixed material turntable 22 to rotate and remain stable.
