The application provides a three-dimensional revolving stage specifically can include: a first turntable mechanism, a second turntable mechanism and a third turntable mechanism;
the first rotary table mechanism is connected with the second rotary table mechanism, and a second rotary table surface 2 of the second rotary table mechanism is vertical to a first rotary table surface 1 of the first rotary table mechanism;
the second rotary table mechanism is connected with the third rotary table mechanism, and a third rotary table surface 3 of the third rotary table mechanism is respectively vertical to the first rotary table surface 1 and the second rotary table surface 2. More specifically, the external devices respectively disposed on the first rotary table top 1, the second rotary table top 2 and the third rotary table top 3 can be respectively connected with the first rotary table mechanism, the second rotary table mechanism and the third rotary table mechanism to perform rotary motion. The second rotary table surface 2 is vertical to the first rotary table surface 1, so that an external device connected to the second rotary table mechanism can perform two-dimensional motion; and because the third rotary table surface 3, the second rotary table surface 2 and the first rotary table surface 1 are in a vertical state, when the external device is connected to the third rotary table mechanism, the external device performs three-dimensional motion. It should be noted that the rotation mode of the external device connected to each turntable mechanism is a rotational motion. In addition, the external device can perform a rotation motion because each rotating table performs a rotation motion.
According to the three-dimensional turntable, the rotary table surface of the first turntable mechanism rotates to drive the second turntable mechanism to rotate; the third rotary table mechanism is driven to rotate by the rotary table surface of the second rotary table mechanism; because the first rotary table top 1, the second rotary table top 2 and the third rotary table top 3 are mutually perpendicular, the external device connected to the third rotary table top 3 can move in two dimensions or three dimensions. The three turntable mechanisms have simple structures, so that the three turntable mechanisms have better operability and are easy to disassemble and assemble.
Next, a three-dimensional turntable in the present exemplary embodiment will be further described.
As an example, the third turntable mechanism includes a third support frame 4, a third motor 5, and a third rotating member;
the third support frame 4 is connected to the rotary table surface of the second turntable mechanism;
the third motor 5 is connected with the third support frame 4 and arranged on one side surface of the third support frame 4;
the third rotating piece is arranged on the other side surface of the third supporting frame 4;
and a motor output shaft of the third motor 5 penetrates through the third support frame 4 to be connected with the third rotating member. More specifically, in order to drive the third rotating member to rotate, a third motor 5 is further provided, and a motor output shaft of the third motor 5 is connected with the third rotating member; meanwhile, in order to fix the positions of the third motor 5 and the third rotating member, a third supporting frame 4 is further arranged, and the third motor 5 and the third rotating member are respectively fixedly connected to two side surfaces of the third supporting frame 4 through threads.
As an example, the third rotation member includes a third limiting member 6 and the third rotation table 3;
the third limiting part 6 is connected with the third rotating table-board 3;
a groove is formed in one surface, facing the third limiting part 6, of the third support frame 4;
a boss is arranged on the third limiting part 6;
the protruding part is embedded in the groove.
As an example, the motor output shaft of the third motor passes through the third limiting member 6 and is connected to the third rotary table top 3. More specifically, the third position-limiting part 6 is fixedly connected to the third rotating table top 3, and the motor output shaft of the third motor 5 passes through the third position-limiting part 6 and is connected to the third rotating table top 3, so that when the motor output shaft of the third motor 5 drives the third rotating table top 3, the third position-limiting part 6 can also rotate accordingly. Therefore, the groove is mainly used for limiting the third limiting part 6 conveniently; the boss may be integrally formed with the third retaining member 6. It should be noted that, since the protrusion is inserted into the groove, the third limiting member 6 can perform a rotational movement.
As an example, a clamping member is connected to a surface of the third rotating table top 3 away from the third limiting member 6;
and the clamping piece is provided with an inserting through hole. More specifically, when the third motor 5 drives the third rotating member to perform a rotating motion, the external device is clamped by the clamping member, thereby being indirectly connected to the third rotating table 3 and rotating along with the rotation of the third rotating member.
As an example, a cavity is arranged inside the third rotating member, and a transmission part is arranged in the cavity;
a motor output shaft of the third motor 5 penetrates through the third limiting piece 6 and is connected with the transmission part; the transmission part is connected with the third rotary table top 3. The transmission part comprises an input gear shaft, a gear ring, a planetary gear and an output gear shaft;
the number of the planetary gears is at least 3;
the planetary gear is arranged in the ring of the gear ring and is meshed with the gear ring;
a motor output shaft of the third motor 5 is connected with the input gear shaft;
one end of the input gear shaft, which is far away from the motor output shaft of the third motor 5, is meshed with the planetary gear;
one end of the output gear shaft is engaged with the planetary gear, and the other end is connected with the third rotary table-board 3. More specifically, the third motor 5 can drive the transmission part to rotate instead of driving the third rotary table-board 3 to rotate. The gear ring in the transmission part is fixed in the cavity, and in order to enable the gear ring to be fixed better, the cavity is cylindrical, and the gear ring is fixedly attached to the inner wall of the cylinder; the planetary gears are arranged in the accommodating space of the gear ring and are in meshed transmission with the gear ring, and meanwhile, the planetary gears are also in meshed transmission. It should be noted that the gear shaft and the motor output shaft need to be connected through an intermediate coupling. Meanwhile, the output gear shaft drives the third rotating part to rotate by being connected with the third rotating table board 3, so that the meshing between the output gear shaft and the planetary gears needs to be stable, 3 or more than 3 planetary gears are needed to be arranged, and at the moment, a through hole can be formed by the mutual meshing between the planetary gears, so that the position clamping effect can be realized on the output gear shaft.
As an example, the number of the planetary gears is at least 4. More specifically, in order to guarantee that the stress of each planetary gear is more balanced for the transmission is more steady, the number of planet wheel is 4. Because the through hole space that 3 planetary gears played formation is too narrow and small, and the uneven condition of each planetary gear atress appears easily, so in order to enlarge this through hole space, make the atress between the planetary gear more even, set up 4 or more than 4 planetary gears of intermeshing better.
As an example, the first turntable mechanism includes a first support frame 10, a first motor 11 and a first rotating member;
the first support frame 10 is arranged at the bottom of the first rotating member and used for supporting the first rotating member;
the first motor 11 is arranged at the bottom of the first rotating member, and a motor output shaft of the first motor 11 penetrates through the first support frame 10 to be connected with the first rotating member. More specifically, in order to drive the first rotating member to perform a rotating motion, a first motor 11 is further provided, and a motor output shaft of the first motor 11 is connected with the first rotating member; meanwhile, in order to support the positions of the first motor 11 and the first rotating member, a first support frame 10 is further provided, and the first motor 11 and the first rotating member are respectively connected to two side surfaces of the first support frame 10. It should be noted that the first supporting frame 10 is generally used as a bottom support of the whole three-dimensional turntable, and when one end of the first supporting frame 10 is connected with the ground, it mainly plays a role of supporting the first rotating member, because the first motor 11 can be directly placed on the ground. In other embodiments, the first turntable mechanism may also be provided with a transmission portion, as in the third turntable mechanism, through the cooperation of each functional element in the transmission portion, the first rotary table top 1 is rotated through a rotation shaft like an output gear shaft. In addition, the first rotating member is formed by connecting a first rotating table top 1 and a first limiting member 12; when the motor output shaft of the first motor 11 drives the first rotating table top 1 to rotate, the first limiting member 12 also rotates.
As an example, the second turntable mechanism includes a second support frame 7, a second motor 8, and a second rotating member;
the second support frame 7 is connected to the rotary table surface of the first turntable mechanism;
the second motor 8 is connected with the second support frame 7 and arranged on one side surface of the second support frame 7;
the second rotating piece is arranged on the other side surface of the second supporting frame 7;
and a motor output shaft of the second motor 8 penetrates through the second support frame 7 to be connected with the second rotating member. More specifically, in order to drive the second rotating member to rotate, a second motor 8 is further arranged, and a motor output shaft of the second motor 8 is connected with the second rotating member; meanwhile, in order to support the positions of the second motor 8 and the second rotating member, a second support frame 7 is further arranged, and the second motor 8 is fixedly connected to one side face of the second support frame 7 through threads. In other embodiments, the second turntable means may also be provided with a transmission portion, as in the third turntable means, through cooperation of the various functions in the transmission portion, the second rotary table top 2 is rotated through a rotation shaft like an output gear shaft. In addition, the second rotating part is formed by connecting a second rotating table top 2 and a second limiting part 9; when the motor output shaft of the second motor 8 drives the second rotating table top 2 to rotate, the second limiting member 9 also rotates.
The above embodiments are only used to illustrate the technical solutions of the present application, and not to limit the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present application.
