Description

Technical Field

[0001] This utility model relates to the field of rotating platform technology, and specifically to a support base for a rotating platform. Background Technology

[0002] A rotary platform consists of a central rotating shaft, a worktable, and support bases distributed circumferentially around the rotating shaft. The bottom surface of the worktable rolls in contact with the support bases, and the worktable rotates around the rotating shaft. Sliding friction occurs between the bottom surface of the worktable and the bearings on the upper part of the support bases. However, existing rotary platform support bases often use deep groove ball bearings for the top bearing portion, with the contact area between the bearing and the rotating platform being a straight line. If the angular position loosens or shifts during platform rotation, the direction of force can easily change, increasing frictional resistance. Furthermore, existing support bases do not monitor platform rotation in real time, failing to guarantee the safety of the platform during use. Therefore, a new type of support base for rotary platforms is proposed. Utility Model Content

[0027] like Figures 1 to 3 As shown, a support base for a rotating platform includes a mounting base 1, which is a U-shaped cylindrical base. Connecting frames 11 are arranged in a circumferential array at equal intervals on the side of the mounting base 1 and are fixedly mounted on the side of the mounting base 1 by screws. The connecting frames 11 are rectangular frames with indicator lines evenly spaced on their sides. Fixing frames 12 are arranged at equal intervals on the side of the connecting frames 11 away from the mounting base 1 and are fixedly mounted on the side of the connecting frames 11 by screws. A turntable 13 is movably arranged on the upper side of the mounting base 1 and is rotatably mounted on the side of the mounting base 1 by a constraint member. The turntable 13 is a circular gear platform. A worktable 2 is fixedly arranged on the upper side of the turntable 13. The worktable 2 is a circular platform composed of a ring and a rectangular rod. A drive mechanism 3 capable of emergency disabling is provided on the side of the mounting base 1. A support mechanism 4 capable of supporting self-detection is provided on the side of the connecting frames 11 corresponding to the worktable 2.

[0028] Specifically, the drive mechanism 3 can drive the worktable 2 normally and can perform a failure braking auxiliary operation in an emergency. The support mechanism 4 can support the rotation of the worktable 2 and can detect the rotation status of the worktable 2, thus ensuring the normal use of the worktable 2 during rotation.

[0029] like Figure 2 , Figure 4 and Figure 5As shown, the drive mechanism 3 includes a drive assembly 31 fixedly installed on the side of the mounting base 1 corresponding to the position of the turntable 13. The drive assembly 31 consists of a drive gearbox and a drive motor. A connecting shaft 32 is provided on the side of the output shaft of the drive assembly 31, and the connecting shaft 32 is fixedly installed on the side of the output shaft of the drive assembly 31 via a coupling. The connecting shaft 32 is a cylindrical shaft with a U-shaped cross-section and a hollowed-out side. A mating gear 33 is movably sleeved on the side of the connecting shaft 32 and meshes with the turntable 13. The mating gear 33 is a ring gear with a spline groove on its inner side. On the inner side of the connecting shaft 32, corresponding to the position of the mating gear 33, there are circumferentially arranged movable cavities 34 that penetrate through it. The movable cavities 34 are U-shaped cavities. Inside the movable cavities 34, movable cavities are arranged in a circular array at equal intervals. A movable block 35 is installed and extends to the inner side of the connecting shaft 32. The movable block 35 is a convex block with teeth on one side. A support block 36 is symmetrically and equidistantly fixed between the side of the movable block 35 and the inner wall of the movable cavity 34. The support block 36 is a "W"-shaped block made of spring steel. A first electric actuator 37 is fixedly installed on the inner side of the connecting shaft 32. A trigger block 371 is fixedly sleeved on the side of the output end of the first electric actuator 37. The trigger block 371 is a circular ring block with a trapezoidal cross section. A second electric actuator 38 is vertically fixedly installed on the upper side of the drive group 31 at the intersection position of the gear 33 and the turntable 13. A damping block 39 is fixedly installed on the output end of the second electric actuator 38. The damping block 39 is a cylindrical block made of elastic rubber.

[0030] Specifically, in the default state, the first electric actuator 37 pulls the trigger block 371 to press it to the side position of the movable block 35. The movable block 35 pulls the support block 36 to deform and engage with the inner position of the movable cavity 34. At this time, when the drive group 31 starts the connecting shaft 32 to rotate, it can drive the mating gear 33 to mesh with the turntable 13, driving the turntable 13 to complete the rotation of the worktable 2. In an emergency, the first electric actuator 37 pushes the trigger block 371 to disengage from the side position of the movable block 35. Under the elastic pulling force of the support block 36, the movable block 35 resets and disengages from the inner position of the movable cavity 34. At this time, the mating gear 33 will quickly lose kinetic energy. Simultaneously, the second electric actuator 38 can push the damping block 39 to rise and press it at the meshing point of the mating gear 33 and the turntable 13 to play a braking role.

[0031] like Figure 2 , Figure 6 and Figure 7As shown, the support mechanism 4 includes a movable seat 41 disposed on the upper side of the connecting frame 11 and fixed to the side of the connecting frame 11 by screws. The movable seat 41 is a "C"-shaped seat, and an opening 42 is formed on the upper side of the movable seat 41. The opening 42 is a rectangular cavity, and a support wheel 43 is disposed inside the opening 42 and is attached to the lower side of the worktable 2. The support wheel 43 is a circular wheel with a cross-shaped cross section and beveled on both sides. A support frame 44 is movably sleeved on the side of the support wheel 43 and is movably installed inside the opening 42. The support frame 44 is a "C"-shaped frame with a circular groove on the side. The inner walls of 42 are mirror-imageed with a mounting cavity 45 that penetrates the movable seat 41. The mounting cavity 45 is a cylindrical cavity. A constraint rod 46 is movably installed inside the mounting cavity 45 and is fixedly installed on the side of the support frame 44. The constraint rod 46 is a cylindrical rod. A support cylinder 47 is movably sleeved on the side of the constraint rod 46 and is fixedly connected between the side of the support frame 44 and the inner wall of the cavity 42. The support cylinder 47 is a spring steel cylinder with a continuous "W" shaped cross section. A detection block 48 is fixedly installed inside the mounting cavity 45. The detection block 48 is a photoelectric sensor (this technical solution is not limited; any sensor that can obtain a signal when an object approaches is acceptable).

[0032] Specifically, the support wheel 43 can support and guide the worktable 2. When the worktable 2 rotates and deviates by an angle, the worktable 2 is pressed against the side of the support wheel 43. The support wheel 43 drives the support frame 44 to slide inside the cavity 42. At the same time, the constraint rod 46 slides inside the mounting cavity 45 to guide and constrain. The signal can be detected by the detection block 48, so that it can be detected whether the position of the worktable 2 is deviated when it rotates.

[0033] In summary: The support mechanism 4 allows for the adjustment and adaptation of the worktable 2 during support operations, and also provides auxiliary detection of the rotational state of the worktable 2 during support, ensuring the stability of the worktable 2's rotation. Simultaneously, the drive mechanism 3 enables normal drive rotation of the worktable 2. Furthermore, the drive mechanism 3 can trigger a disabling operation when the support mechanism 4 detects an abnormal rotational state of the worktable 2, preventing the drive assembly 31 from continuing to drive the worktable 2's rotation due to inertia when it stops. Moreover, the drive mechanism 3 can trigger a braking operation on the worktable 2, preventing accidents caused by abnormal rotation or delayed braking. Overall, this ensures the normal rotational movement of the worktable 2.
