[0005] In practical applications, rotary tables are widely used in automated production lines, CNC machine tools, assembly equipment and other fields.

[0006] The above-mentioned prior art solutions have the following defects: in actual work, in order to facilitate the operation of workers, sometimes it is necessary not only to rotate the workbench, but also to lift the workbench, and most of the existing rotary workbenches do not have a lifting function. Summary of the invention

[0007] In order to enable a rotary table to be raised and lowered, the present application provides a rotary table for electrical automation equipment.

[0008] The above technical objectives of this application are achieved through the following technical solutions:

[0009] A rotary workbench for electrical automation equipment comprises a rotary shell, a cylindrical tube is arranged inside the rotary shell, a transmission ring is rotatably connected above the cylindrical tube, gear teeth are arranged on the outer side of the transmission ring, a driving motor is fixedly connected inside the rotary shell, an output shaft of the driving motor is connected to a driving gear, and the driving gear meshes with the gear teeth on the outer side of the transmission ring, a thread is arranged on the inner side of the transmission ring, and the transmission ring is connected to a threaded column through the thread, the threaded column is inserted into the cylindrical tube at the lower end, a column rod is fixedly connected at the upper end of the threaded column, a working platform is fixedly connected at the upper end of the column rod, a disc is rotatably connected above the rotary shell, the column rod passes through the disc and the column rod is slidably connected to the disc, the disc is connected to a disc ring fixing structure capable of fixing the disc to the transmission ring, and the disc is connected to a disc shell fixing structure capable of fixing the disc to the rotary shell.

[0010] By adopting the above scheme, in the initial state, the disc is connected to the rotating shell in rotation, the disc ring fixing structure fixes the disc to the transmission ring, the driving motor rotates to drive the driving gear to rotate, thereby driving the transmission ring to rotate, the transmission ring drives the disc and the threaded rod to rotate, thereby driving the column rod and the working platform to rotate, thereby realizing the rotation of the working platform. When the working platform needs to be raised or lowered, the disc shell fixing structure fixes the disc to the rotating shell, the disc ring fixing structure is unlocked to make the disc connected to the transmission ring in rotation, at this time, the driving motor rotates, the driving gear drives the transmission ring to rotate, because the transmission ring and the threaded rod are connected by threads, and because the disc is fixed to the rotating shell, the disc is connected to the column rod in a sliding manner, and the column rod is fixed to the threaded rod, so the threaded rod and the transmission ring rotate relative to each other, thereby driving the threaded rod to move in the vertical direction, thereby realizing the lifting or lowering of the working platform.

[0011] Optionally, the column rod has a polygonal cross section, and a polygonal hole having the same shape as the cross section of the column rod is opened in the middle of the disk.

[0012] By adopting the above solution, the relative rotation between the column rod and the disk is restricted, so that the column rod and the disk can only slide relative to each other.

[0013] Optionally, a support spring is provided inside the cylindrical tube, and a top plate is fixedly connected to one end of the support spring close to the threaded column, and the top plate abuts against the lower surface of the threaded column.

[0014] By adopting the above solution, the support spring supports the threaded column and shares the force borne by the transmission ring.

[0015] Optionally, a first pressure bearing is provided between the top plate and the threaded column.

[0016] By adopting the above solution, the friction force between the threaded column and the top plate during relative rotation is reduced, thereby reducing energy loss.

[0017] Optionally, a disc groove is provided on the upper surface of the rotating shell, a second pressure bearing is arranged in the disc groove, and the disc is rotatably connected in the disc groove via the second pressure bearing.

[0018] By adopting the above solution, the friction force between the rotating housing and the disc during relative rotation is reduced, thereby further reducing energy loss.

[0019] Optionally, a circle of annular grooves are provided on the circumferential surface of the disc, and a circle of annular sliders are provided on the side surface of the disc groove, and the annular sliders are slidably connected in the annular grooves.

[0020] By adopting the above solution, the disc can only slide in the disc groove, thereby preventing the disc from being separated from the rotating shell.

[0021] Optionally, a disk shell fixing cavity is opened in the disk, and the disk shell fixing cavity is connected to the upper surface of the annular groove. The disk shell fixing structure includes a first clamping rod, and the first clamping rod is slidably connected to a guide rod near the center position. Both ends of the guide rod are fixedly connected to the disk, and one end of the first clamping rod is located at the connection point between the disk shell fixing cavity and the annular groove. The other end of the first clamping rod is connected to a threaded rod, and the first clamping rod is fixedly connected to one end of the threaded rod, and the threaded rod is threadedly connected to the disk.

[0022] By adopting the above scheme, the operator can rotate the threaded rod to move the threaded rod downward, thereby moving the first clamping rod downward, so that the first clamping rod and the disc clamp the ring slider, thereby fixing the disc and the rotating shell; when it is necessary to rotate the disc and the rotating shell, the threaded rod can be moved upward, so that the first clamping rod can be moved upward, thereby allowing the disc and the rotating shell to rotate relative to each other.

[0023] Optionally, a rubber sleeve is provided on the first clamping rod at the connection point between the disk shell fixing cavity and the annular groove.

[0024] By adopting the above solution, the friction between the first clamping rod and the ring slider is increased, so that when the disk and the rotating shell need to be fixed, the disk and the rotating shell are fixed more firmly.

[0025] Optionally, the disc ring fixing structure includes a limit plate, which is fixedly connected to the end of the threaded rod away from the first clamping rod. An annular groove is opened on the upper surface of the transmission ring, and the cross-section of the annular groove is an inverted T shape. The limit plate is located inside the annular groove.

[0026] By adopting the above scheme, when the disc and the transmission ring need to be fixed, the threaded rod is rotated to move the threaded rod upward, so that the annular sheet moves upward, so that the annular sheet is pressed against the surface of the annular groove, thereby fixing the disc and the transmission ring. When the disc and the transmission ring need to be released, the threaded rod is moved downward to separate the annular sheet from the surface of the annular groove, thereby separating the disc and the transmission ring.

DETAILED DESCRIPTION

[0038] The present application is further described in detail below with reference to the accompanying drawings.

[0039] Reference Figure 1 and Figure 2A rotary workbench for electrical automation equipment includes a rotary shell 1, a cylindrical tube 12 is arranged inside the rotary shell 1, a transmission ring 2 is rotatably connected above the cylindrical tube 12, gear teeth are arranged on the outside of the transmission ring 2, and a driving motor 11 is fixedly connected inside the rotary shell 1, and the output shaft of the driving motor 11 is connected to a driving gear 111, and the driving gear 111 is meshed with the gear teeth on the outside of the transmission ring 2. A thread is arranged on the inside of the transmission ring 2, and the transmission ring 2 is connected to a threaded column 3 through the thread, the threaded column 3 is inserted into the cylindrical tube 12 at the lower end, the threaded column 3 is fixedly connected to a column rod 31 at the upper end, and the column rod 31 is fixedly connected to a working platform 8 at the upper end, a disc 4 is rotatably connected above the rotary shell 1, the column rod 31 passes through the disc 4 and the column rod 31 is slidably connected to the disc 4, the disc 4 is connected to a disc ring fixing structure that can fix the disc 4 to the transmission ring 2, and the disc 4 is connected to a disc shell fixing structure that can fix the disc 4 to the rotary shell 1.

[0040] Reference Figure 1 and Figure 2 In the initial state, the disc 4 is connected to the rotating shell 1 in rotation, the disc ring fixing structure fixes the disc 4 to the transmission ring 2, the driving motor 11 rotates to drive the driving gear 111 to rotate, thereby driving the transmission ring 2 to rotate, the transmission ring 2 drives the disc 4 and the threaded rod 5 to rotate, thereby driving the column 31 and the working platform 8 to rotate, thereby realizing the rotation of the working platform 8. When the working platform 8 needs to be raised or lowered, the disc shell fixing structure fixes the disc 4 to the rotating shell 1, the disc ring fixing structure is unlocked to make the disc 4 connected to the transmission ring 2 in rotation, at this time, the driving motor 11 rotates, the driving gear 111 drives the transmission ring 2 to rotate, because the transmission ring 2 and the threaded rod 5 are connected by threads, and because the disc 4 is fixed to the rotating shell 1, the disc 4 is connected to the column 31 in a sliding manner, and the column 31 is fixedly connected to the threaded rod 5, so the threaded rod 5 and the transmission ring 2 rotate relative to each other, thereby driving the threaded rod 5 to move in the vertical direction, thereby realizing the lifting and lowering of the working platform 8.

[0041] Reference Figure 1 and Figure 2 A support spring 121 is arranged inside the cylindrical tube 12, one end of the support spring 121 is fixedly connected to the bottom of the cylindrical tube 12, and the upper end of the support spring 121 is fixedly connected to a top plate 122, and a pressure bearing is arranged between the top plate 122 and the threaded column 3, so that the friction force when the top plate 122 and the threaded column 3 rotate relative to each other is smaller, and the support spring 121 is always in a compressed state. The support spring 121 provides support for the threaded rod 5 and the working platform 8, thereby reducing the burden of the transmission ring 2, making the rotation of the transmission ring 2 smoother, and reducing the wear of the transmission ring 2, so that the service life of the rotary table is longer.

[0042] Reference Figure 1 and Figure 2 A polygonal hole 44 is provided at the center of the disk 4, and the cross section of the column 31 is in a polygonal shape with the same shape as the polygonal hole 44, and the column 31 passes through the polygonal hole 44. When the disk 4 is fixed to the rotating shell 1, the disk 4 limits the rotation of the column 31, so that the column 31 slides in the vertical direction, thereby realizing the lifting and lowering of the working platform 8. A disc groove 13 is provided on the upper surface of the rotating shell 1, and the disk 4 is rotatably connected in the disc groove 13. A second pressure bearing 132 is provided on the lower surface of the disk 4, and the disk 4 is rotatably connected in the disc groove 13 through the second pressure bearing 132, thereby reducing the friction between the disk 4 and the rotating shell 1 when the disk 4 rotates. An annular groove 41 is provided on the circumferential surface of the disk 4, and a ring slider 131 is provided on the side surface in the disc groove 13, and the ring slider 131 is located in the annular groove 41, thereby further limiting the movement of the disk 4 in the vertical direction, so that the transmission of the rotating workbench is smoother.

[0043] Reference Figure 2 and Figure 3 A disk housing fixing cavity 42 is provided in the disk 4, and the disk housing fixing cavity 42 is connected to the upper surface of the annular groove 41. The disk housing fixing structure includes a first clamping rod 6, and the first clamping rod 6 is slidably connected to a guide rod 62 near the center position. Both ends of the guide rod 62 are fixedly connected in the disk housing fixing cavity 42, and one end of the first clamping rod 6 is located at the connection point between the disk housing fixing cavity 42 and the upper surface of the annular groove 41, and the first clamping rod 6 is fixedly connected to the rubber sleeve 61 at this end, and the other end of the first clamping rod 6 is fixedly connected to the threaded rod 5. When it is necessary to fix the disk 4 to the rotating housing 1, it is only necessary to move the threaded rod 5 downward to move the first clamping rod 6 downward, so that the first clamping rod 6 and the disk 4 clamp the ring slider 131, and the rubber sleeve 61 increases the friction between the first clamping rod 6 and the ring slider 131, so that the disk 4 is fixedly connected to the rotating housing 1.

[0044] Reference Figure 2 and Figure 3 A column tube 43 is provided at the place where the threaded rod 5 passes through the disc 4. The column tube 43 is fixedly connected to the disc 4, and a driven gear 72 is rotatably connected to the end of the column tube 43 away from the disc 4. A state-changing motor 7 is fixedly connected to the lower surface of the disc 4. The output shaft of the state-changing motor 7 is fixedly connected to the rotating gear. The driving gear 71 is meshed with the driven gear 72. The inner surface of the driven gear 72 is provided with a thread, and the driven gear 72 is connected to the threaded rod 5 through a thread. The rotation of the driving motor 11 drives the driving gear 71 to rotate, thereby driving the driven gear 72 to rotate. Since the driven gear 72 is threadedly connected to the threaded rod 5, and the threaded rod 5 is fixedly connected to the first clamping plate, when the driven gear 72 rotates, the threaded rod 5 will translate in the vertical direction, thereby realizing the upward and downward movement of the threaded rod 5.

[0045] Reference Figure 4An annular groove 21 with an inverted T-shaped cross section is provided on the upper surface of the transmission ring 2. One end of the threaded rod 5 that is away from the first clamping rod 6 penetrates into the annular groove 21, and this end of the threaded rod 5 is fixedly connected to a limiting plate 51, which is located in the annular groove 21. When the threaded rod 5 moves upward, the limiting plate 51 is pressed against the upper surface of the annular groove 21. Therefore, when the working platform 8 needs to be rotated, the transposition motor drives the threaded rod 5 to move upward, so that the limiting plate 51 is pressed against the upper surface of the annular groove 21, so that the disc 4 is fixedly connected to the transmission ring 2, and then the driving motor 11 drives the driving gear 111 to rotate, thereby driving the transmission ring 2 to rotate, thereby driving the disc 4 and the column rod 31 to rotate, thereby realizing the rotation of the working platform 8.

[0046] The specific implementation principle of the present application is: in the initial state, the limit plate 51 is pressed against the upper surface of the annular groove 21, so that the disc 4 is fixedly connected to the transmission ring 2, and the disc 4 is rotationally connected to the rotating shell 1. The disc-ring fixing structure fixes the disc 4 and the transmission ring 2, and the driving motor 11 rotates to drive the driving gear 111 to rotate, thereby driving the transmission ring 2 to rotate, and the transmission ring 2 drives the disc 4 and the threaded rod 5 to rotate, thereby driving the column rod 31 and the working platform 8 to rotate, thereby realizing the rotation of the working platform 8. When it is necessary to lift the working platform 8, the state-changing motor 7 rotates to drive the driving gear 71 to rotate, thereby driving the driven gear 72 to rotate, thereby driving the threaded rod 5 to move downward, and the threaded rod 5 drives the limiting plate 51 to move downward, so that the limiting plate 51 is separated from the inner wall of the annular groove 21, so that the disc 4 and the transmission ring 2 are released from fixation. At the same time, the threaded rod 5 drives the first clamping rod 6 to move downward, so that the first clamping rod 6 and the disc 4 clamp the ring slider 131, and the disc 4 is fixedly connected to the rotating shell 1. At this time, the driving motor 11 rotates, and the driving gear 111 drives the transmission ring 2 to rotate. Since the transmission ring 2 and the threaded rod 5 are threadedly connected, and since the disc 4 is fixed to the rotating shell 1, the disc 4 is slidably connected to the column rod 31, and the column rod 31 is fixedly connected to the threaded rod 5, the threaded rod 5 and the transmission ring 2 rotate relative to each other, thereby driving the threaded rod 5 to move in the vertical direction, thereby realizing the lifting and lowering of the working platform 8.

[0047] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
