The cylinders have a long action cycle, slow speed, high noise, and wires or air pipes move and flip along with it, which are easy to break and occupy space; it is inconvenient for installation and debugging. Summary of the Invention

[0003] Purpose of the utility model: In order to overcome the deficiencies of the background art, the utility model discloses a high-speed flipping mechanism for a cylindrical cam.

[0004] Technical solution: The high-speed flipping mechanism for a cylindrical cam described in the utility model includes: a servo motor, which is fixed on an installation base plate, and an installation round shaft is provided at its driving end. A cylindrical cam is connected to the installation round shaft through a pedestal bearing. A cam groove structure protruding towards the servo motor is provided on the outer wall of the cylindrical cam. The extended end of the installation round shaft is fixed with a product carrier seat. The protruding position of the cam groove of the cylindrical cam faces one side of the product carrier seat. The product carrier seat rotates with the drive of the servo motor. Linear guide rails are respectively fixed at the positions corresponding to the two sides of the product carrier on the installation round shaft. Cover plate connection blocks are fixed on the sliding surfaces of the linear guide rails. Cam bearing connection blocks are fixed on the cover plate connection blocks. Cam bearings matching the cam groove are respectively fixed on the cam bearing connection blocks. As the installation round shaft rotates, the cam bearings roll circumferentially in the cam groove, and when passing through the protruding position of the cam groove, the rotation is converted into the axial displacement of the cover plate connection blocks. Load-bearing seat cover plates are provided at the axial ends of the cover plate connection blocks. The upper and lower load-bearing seat cover plates alternately open / close when the product carrier seat flips with the periodic axial displacement of the cover plate connection blocks.

[0005] Further, the driving end of the servo motor is sequentially connected with a reducer and a coupling, and is fixed on the installation base plate through a motor mounting plate.

[0006] Further, the pedestal bearing is fixed on the installation base plate through a cam mounting plate, and the cylindrical cam is axially and circumferentially fixed thereby.

[0007] Further, the extended end of the installation round shaft is installed on a bearing mounting plate through a round shaft bearing, and is fixed on the installation base plate through the bearing mounting plate.

[0008] Further, the cover plate connection blocks all axially pass through the round shaft bearings and fix the load-bearing seat cover plates.

[0009] Further, the bearing mounting plate and the cam mounting plate are fixed by an axial support plate, and the axial support plate is fixed to the mounting base plate.

[0010] Advantages: Compared with the prior art, the advantages of the present utility model are as follows: By adopting a motor drive + cam mechanism, it only takes 0.15S to realize front and back flipping. The mechanism has a small volume and saves space. The mechanism is simple and practical to operate. Parameter visualization adjustment can be achieved in the program, and it has wide applicability; with high efficiency and accuracy, it greatly improves the equipment stability and production efficiency, thereby improving economic benefits.

[0015] The technical solution of the present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0016] As Figures 1-3 shown in the cylindrical cam high-speed flipping mechanism, which includes: a servo motor 1, the servo motor 1 is fixed to the mounting base plate 2, and its driving end is provided with a mounting circular shaft 3. A cylindrical cam 4 is connected to the mounting circular shaft 3 through a pedestal bearing 6. The outer wall of the cylindrical cam 4 is provided with a cam groove structure protruding towards the servo motor 1 side. The extended end of the mounting circular shaft 3 is fixed with a product carrier 5. The protruding position of the cam groove of the cylindrical cam 4 is opposite to one side of the product carrier 5. The product carrier 5 rotates with the drive of the servo motor 1. Linear guide rails 7 are respectively fixed to the mounting circular shaft 3 at the positions corresponding to the two sides of the product carrier 5. Cover connection blocks 10 are fixed to the sliding surfaces of the linear guide rails 7. Cam bearing connection blocks 8 are respectively fixed to the cover connection blocks 10. Cam bearings 9 matching the cam groove are respectively fixed to the cam bearing connection blocks 8. As the mounting circular shaft 3 rotates, the cam bearings 9 roll circumferentially in the cam groove, and when passing through the protruding position of the cam groove, the rotation is converted into the axial displacement of the cover connection blocks 10. Loading seat covers 11 are respectively provided at the axial ends of the cover connection blocks 10. The upper and lower two loading seat covers 11 alternately open / close when the product carrier 5 is flipped with the periodic axial displacement of the cover connection blocks 10.

[0017] The driving end of the servo motor 1 is sequentially connected to the speed reducer 12 and the coupling 13, and is fixed to the mounting base plate 2 through the motor mounting plate 14.

[0018] The pedestal bearing 6 is fixed to the mounting base plate 2 through the cam mounting plate 15, and the cylindrical cam 4 is thereby axially and circumferentially fixed.

[0019] The extended end of the mounting circular shaft 3 is mounted on the bearing mounting plate 17 through the circular shaft bearing 16, and is fixed to the mounting base plate 2 through the bearing mounting plate 17.

[0020] The cover connection block 10 axially passes through the circular shaft bearing 16 and fixes the carrier cover 11.

[0021] The bearing mounting plate 17 and the cam mounting plate 15 are fixed by the axial support plate 18, and the axial support plate 18 is fixed to the mounting base plate 2.

[0022] When the servo motor 1 rotates to drive the mounting circular shaft 3 and the product carrier 5 to rotate, the cam bearing 9 moves the slider to act on the cam track. When the rotation angle of the servo motor reaches 5 degrees, the carrier cover 11 starts to close. Until the rotation angle reaches 35 degrees, the carrier cover 11 is completely closed. When the rotation angle is 355 degrees, the carrier cover 11 is completely opened; the product will not fall when it is turned over on the product carrier 5, so as to achieve the effect that the cover alternately opens and closes when the product carrier 5 is turned over.
