DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0018] like Figure 1-Figure 4As shown, a driving device for cavity swinging includes a driving motor 1, a connecting rod 4, and a mounting base 5. The driving motor 1 is driven and connected to a flange 2. One end of the connecting rod 4 is mounted on the flange 2 by bolts. A plurality of mounting holes 3 are opened on the flange 2. The mounting holes 3 are threaded holes. Different mounting holes 3 have different distances from the center of the flange 2. The bolt passes through the connecting rod 4 and is screwed into one of the mounting holes 3. A rotating shaft 6 is rotatably arranged in the mounting base 5. Both ends of the rotating shaft 6 are arranged through the mounting base 5. A fixing sleeve 7 is sleeved on one end of the rotating shaft 6. The rotating shaft 6 and the fixing sleeve 7 are fixedly connected. A rocker arm 8 is connected to the outer periphery of the fixing sleeve 7. One end of the connecting rod 4 away from the flange 2 is rotatably connected to the rocker arm 8, and the other end of the rotating shaft 6 is connected to the cavity by bolts.

[0019] The bolts are screwed into different mounting holes 3 on the flange 2, so that the position of the connecting rod 4 installed on the flange 2 is changed, and then the angle between the connecting rod 4 and the rocker arm 8 is changed. When the driving motor 1 drives the flange 2 to rotate, the rocker arm 8 swings back and forth at different angles, thereby changing the swing angle of the cavity.

[0020] like Figure 4 As shown, a mounting block 23 is connected to the upper part of the drive motor 1, a proximity switch 24 is arranged on the mounting block 23, and a sensing block 25 is arranged on the periphery of the flange 2. The operation of the drive motor 1 is controlled by the cooperation between the proximity switch 24 and the sensing block 25. When the sensing block 25 is located below the proximity switch 24, the drive motor 1 stops, so that the cavity stops swinging and remains in a horizontal state.

[0021] like Figure 2 As shown, the mounting base 5 is provided with a bearing seat 2 15 and a bearing seat 1 13, and the middle positions of the bearing seat 2 15 and the bearing seat 1 13 are respectively provided with a bearing 2 16 and a bearing 14, and the rotating shaft 6 is rotatably arranged in the bearing 2 16 and the bearing 1 14. The outer ring of the bearing 2 16 is fixedly installed in the bearing seat 2 15, and the inner ring of the bearing 2 16 abuts against the rotating shaft 6. The outer ring of the bearing 14 is fixedly installed in the bearing seat 1 13, and the inner ring of the bearing 14 abuts against the rotating shaft 6. The arrangement of the bearing 2 16 and the bearing 1 14 allows the rotating shaft 6 to be rotatably installed on the mounting base 5.

[0022] One end of the rotating shaft 6 on which the fixing sleeve 7 is installed is provided with a fixing end cover 9, and the fixing end cover 9 is fixed to the end of the rotating shaft 6 by bolts. Under the action of the fixing end cover 9, the fixing sleeve 7 is pressed against the inner ring of the bearing 14.

[0023] A rotary oil seal 18 is disposed in the middle of the second bearing seat 15 , and the rotating shaft 6 passes through the rotary oil seal 18 . The rotary oil seal 18 is located on the outside of the second bearing 16 , and the rotary oil seal 18 plays an isolating role to ensure sealing.

[0024] like Figure 3As shown, the device also has a safety locking device, which includes a limit plate 19. The portion of the rotating shaft 6 between the second bearing 16 and the first bearing 14 is installed with the limit plate 19 through a connecting key 20, so that the limit plate 19 rotates with the rotating shaft 6. A limit notch 21 is provided on the limit plate 19. The limit notch 21 is located at the outer periphery of the limit plate 19. The two sides of the limit notch 21 are perpendicular to each other, and one of the sides is arranged along the radial direction of the limit plate 19. The upper part of the mounting base 5 is rotatably connected to the swing arm 12 through the pin 11. The lower part of the mounting base 5 is hinged with a cylinder 10. The upper end of the piston rod of the cylinder 10 is hinged with the swing arm 12. An adjusting screw 22 is installed at one end of the swing arm 12 close to the limit plate 19. When the piston rod of the cylinder 10 extends, it drives the swing arm 12 to rotate in a circle with the pin shaft 11. The end of the swing arm 12 away from the piston rod descends and is inserted into the limiting notch 21 of the limiting plate 19. The adjusting screw 22 on the swing arm 12 abuts against the limiting notch 21, thereby limiting the rotation of the limiting plate 19, and thus limiting the rotation of the cavity. By rotating the adjusting screw 22, the distance between the adjusting screw 22 and the end of the swing arm 12 can be adjusted, thereby adjusting the limiting position of the limiting plate 19 to ensure that the cavity is horizontal when limiting. When swinging is required, the piston rod of the cylinder 10 contracts and the swing arm 12 is lifted, so that the adjusting screw 22 disengages from the limiting notch 21.

[0025] A shaft sleeve 17 is installed on the rotating shaft 6, and the shaft sleeve 17 is located between the limit plate 19 and the bearing 14. One end of the limit plate 19 abuts against the inner ring of the bearing 2 16, and the other end of the limit plate 19 abuts against the shaft sleeve 17. The end of the shaft sleeve 17 away from the limit plate 19 abuts against the inner ring of the bearing 14. The shaft sleeve 17 can limit the position of the limit plate 19 on the rotating shaft 6 to prevent the limit plate 19 from sliding.

[0026] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
