Description

Technical Field

[0001] This utility model relates to the field of hollow rotating platform technology, specifically a hollow rotating platform that is easy to install. Background Technology

[0002] Hollow rotary platforms are used in various rotary motion applications and can replace direct drive motors and cam dividers. They combine high efficiency, high precision, high rigidity, and high cost-effectiveness, achieving a balance between the two. The repeatability positioning accuracy is ≤5 seconds. The motor is easy to configure and has a stable load-bearing capacity. It can be equipped with AC servo motors or stepper motors to perform arbitrary angle division. It can meet the digital control requirements that dividers cannot achieve, and the positioning accuracy is comparable to that of direct drive motors, which can significantly reduce costs.

[0003] Chinese patent CN222096065U discloses a high-precision hollow rotary platform that is easy to install. It includes an L-shaped bracket, a rotating base, and a hollow rotary platform body. The upper end of the L-shaped bracket has a vertical groove, within which a vertical plate is slidably connected. An adjustment assembly for driving the vertical plate to move vertically is mounted on the L-shaped bracket. A horizontal plate is fixedly connected to the upper end of the vertical plate, and a rotating rod is rotatably connected through the horizontal plate. A drive assembly for rotating the rotating rod is mounted at the bottom of the horizontal plate. A support plate is fitted onto the upper part of the rotating rod on the horizontal plate, and a polygonal plate is fixedly connected to the upper end of the rotating rod. This easy-to-install high-precision hollow rotary platform is simple to install, can drive connected mechanical components to rotate, and allows adjustment of the height and rotation radius of the rotary platform body to meet different usage requirements.

[0004] However, the lack of a locking structure for the threaded rod in the vertical plate lifting structure may cause the vertical plate to suddenly move due to unexpected reasons (such as vibration, load changes, etc.) during the lifting and lowering process of the horizontal plate, thus affecting the stability of the rotating platform. Therefore, it is necessary to provide a hollow rotating platform that is easy to install. Utility Model Content

[0005] The purpose of this invention is to provide a hollow rotating platform that is easy to install, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hollow rotating platform that is easy to install, comprising an L-shaped bracket, a horizontal plate, a rotating seat, and a rotating platform body. A first adjustment mechanism is provided between the L-shaped bracket and the horizontal plate, and a second adjustment mechanism is provided between the horizontal plate and the rotating seat. The first adjustment mechanism includes two support rods fixedly arranged at the bottom of the horizontal plate. The L-shaped bracket has a telescopic groove that slides with the support rods. Gear grooves are provided on the opposite surfaces of the two support rods. A movable groove is provided within the telescopic groove, and a drive gear is rotatably arranged within the movable groove. Driven gears are rotatably arranged on both sides of the driving gear within the movable slot. The driving gear meshes with one of the driven gears, and the driving gear and the other driven gear are meshed and driven by an idler gear, which is rotatably arranged within the movable slot. The shaft of the driving gear rotatably passes through the movable slot and is fixedly connected to a rotating plate. A handle is fixedly arranged on the rotating plate, and an insertion hole is provided on the rotating plate. Multiple limiting screw holes are provided on the side of the L-shaped bracket near the rotating plate, and a screw is inserted into the insertion hole. The screw passes through the insertion hole and is threadedly connected to the corresponding limiting screw hole.

[0007] Preferably, the second adjustment mechanism includes a motor installed at the bottom of the horizontal plate, the output shaft of the motor rotatably passing through the horizontal plate and fixedly connected to a support plate, and a rhomboid column is fixedly installed on the support plate.

[0008] Preferably, the rhomboid column has a telescopic cavity, a slider is slidably disposed in the telescopic cavity, a wedge-shaped block is fixedly connected to one side of the slider, and a spring is connected between the other side of the slider and the telescopic cavity.

[0009] Preferably, the rhomboid column has a movable cavity, a rotating rod is rotatably mounted in the movable cavity, a rope wheel is fixedly mounted on the rotating rod, a connecting rope is wound around the rope wheel, and the free end of the connecting rope passes through the movable cavity and extends into the telescopic cavity to connect with the slider.

[0010] Preferably, the top of the rotating rod is rotatably connected through the movable cavity and fixedly connected to a hand-tightening block.

[0011] Preferably, the rotating base has multiple diamond-shaped holes, the diamond-shaped column is inserted into the diamond-shaped holes, and a fixing plate is fixedly installed on both sides of the diamond-shaped holes on the rotating base. The fixing plate has a slot for engaging with the wedge-shaped block.

[0012] Preferably, the L-shaped bracket has a fixing hole and a counterweight is installed on the L-shaped bracket.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1) This easy-to-install hollow rotating platform allows for height adjustment of the rotating seat and platform body by unscrewing the screw from the limiting screw hole and then rotating the rotating plate through the throttle. This causes the driven gear meshing with the driving gear and another driven gear meshing through the idler gear to rotate synchronously in opposite directions. Under the meshing action of the driven gear and the tooth groove, the support rod can extend into the groove and move up and down, thereby achieving height adjustment of the rotating seat and the rotating platform body. After adjustment, the screw is inserted into the insertion hole and screwed into the corresponding limiting screw hole to lock the driving gear and improve the stability of the support rod after adjustment.

[0015] 2) This easy-to-install hollow rotating platform uses a rotating hand-tightening block to wind up the connecting rope, causing the slider to be pulled by the tension of the connecting rope, which drives the wedge-shaped locking block to disengage from the slot and retract into the telescopic cavity. Then, the diamond-shaped hole on the rotating seat is separated from the diamond-shaped column. After extending the rotating seat as needed, the corresponding diamond-shaped hole is fitted onto the diamond-shaped column. At this time, the wedge-shaped locking block is squeezed and retracts into the telescopic cavity, compressing the spring. When the diamond-shaped column is fully inserted into the diamond-shaped hole, the wedge-shaped locking block automatically pops out under the spring's rebound and locks into the slot on the fixed plate, thus locking and fixing the rotating seat. This allows for adjustment of the rotation radius of the rotating platform body as needed. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Combination Figures 1-6 A hollow rotating platform that is easy to install includes an L-shaped bracket 1, a horizontal plate 3, a rotating seat 4 and a rotating platform body 5. The L-shaped bracket 1 has a fixing hole 2 and a counterweight 6 is installed on the L-shaped bracket 1. A first adjustment mechanism 7 is provided between the L-shaped bracket 1 and the horizontal plate 3, and a second adjustment mechanism 8 is provided between the horizontal plate 3 and the rotating seat 4.

[0028] See Figure 5 and Figure 6Furthermore, the first adjusting mechanism 7 includes two relatively fixed support rods 701 at the bottom of the horizontal plate 3. An L-shaped bracket 1 has a telescopic groove 702 that slides through the support rods 701. Gear grooves 703 are formed on the opposing surfaces of the two support rods 701. A movable groove 704 is formed within the telescopic groove 702. A driving gear 705 is rotatably arranged within the movable groove 704. Driven gears 706 are rotatably arranged on both sides of the driving gear 705 within the movable groove 704. The driving gear 705 meshes with one of the driven gears 706. Another driven gear 706 is meshed with an idler gear 707, which is rotatably mounted in the movable slot 704. The shaft of the driving gear 705 rotates through the movable slot 704 and is fixedly connected to a rotating plate 708. A handle 709 is fixedly mounted on the rotating plate 708. An insertion hole 710 is provided on the rotating plate 708. Multiple limiting screw holes 711 are provided on the side of the L-shaped bracket 1 near the rotating plate 708. A screw 712 is inserted into the insertion hole 710 and threadedly connected to the corresponding limiting screw hole 711 through the insertion hole 710.

[0029] Specifically, by unscrewing the screw 712 from the limiting screw hole 711, and then driving the rotating plate 708 through the throttle 709 to rotate the drive gear 705, the driven gear 706 meshing with the drive gear 705 and another driven gear 706 meshing through the idler wheel 707 rotate synchronously in opposite directions. Under the meshing action of the driven gear 706 and the tooth groove 703, the support rod 701 can extend the groove 702 to move up and down, thereby realizing the height adjustment of the rotating seat 4 and the rotating platform body 5. After adjustment, the screw 712 is inserted into the insertion hole 710 and screwed into the corresponding limiting screw hole 711 to lock the drive gear 705 and improve the stability of the support rod 701 after adjustment.

[0030] See Figures 2-4Furthermore, the second adjustment mechanism 8 includes a motor 801 installed at the bottom of the horizontal plate 3. The output shaft of the motor 801 rotatably passes through the horizontal plate 3 and is fixedly connected to a support plate 802. A rhomboid column 803 is fixedly installed on the support plate 802. A telescopic cavity 804 is opened inside the rhomboid column 803. A slider 805 is slidably installed inside the telescopic cavity 804. A wedge-shaped locking block 806 is fixedly connected to one side of the slider 805. A spring 807 is connected between the other side of the slider 805 and the telescopic cavity 804. A movable cavity 808 is opened inside the rhomboid column 803. A rotating rod is rotatably installed inside the movable cavity 808. 809, a rope wheel 810 is fixedly sleeved on the rotating rod 809, a connecting rope 811 is wound on the rope wheel 810, the free end of the connecting rope 811 passes through the movable cavity 808 and extends into the telescopic cavity 804 and connects to the slider 805, the top of the rotating rod 809 rotatably passes through the movable cavity 808 and is fixedly connected to a hand-tightening block 812, a plurality of diamond-shaped holes 813 are opened on the rotating seat 4, diamond-shaped pillars 803 are inserted into the diamond-shaped holes 813, and fixed plates 814 are fixedly installed on both sides of the diamond-shaped holes 813 on the rotating seat 4, and the fixed plates 814 are provided with slots 815 for engaging with the wedge-shaped locking blocks 806.

[0031] Specifically, by rotating the hand-tightening block 812, the rope wheel 810 winds up the connecting rope 811, causing the slider 805 to be pulled by the connecting rope 811, which drives the wedge-shaped locking block 806 to disengage from the slot 815 and retract into the telescopic cavity 804. Then, the diamond-shaped hole 813 on the rotating seat 4 is separated from the diamond-shaped column 803. After extending the rotating seat 4 as needed, the corresponding diamond-shaped hole 813 is fitted onto the diamond-shaped column 803. At this time, the wedge-shaped locking block 806 is squeezed and retracts into the telescopic cavity 804, squeezing the spring 807. When the diamond-shaped column 803 is fully inserted into the diamond-shaped hole 813, the wedge-shaped locking block 806 automatically pops out under the rebound action of the spring 807 and locks into the slot 815 on the fixing plate 814, thus realizing the locking and fixing of the rotating seat 4, which facilitates the adjustment of the rotation radius of the rotating platform body 5 as needed.

[0032] In actual operation, the L-shaped bracket 1 is installed on the workbench through the fixing hole 2, and the mechanical parts that need to be rotated are installed on the rotating platform body 5. The motor 801 drives the support plate 802 to rotate, so that the rhomboid column 803 drives the rotating seat 4 and the rotating platform body 5 to rotate, so that the connected mechanical parts rotate.

[0033] When the height of the rotating seat 4 and the rotating platform body 5 needs to be adjusted, screw 712 is unscrewed from the limiting screw hole 711. Then, the rotating plate 708 is driven by the throttle 709 to rotate the drive gear 705. This causes the driven gear 706 meshing with the drive gear 705 and another driven gear 706 meshing with the idler wheel 707 to rotate synchronously in opposite directions. Under the meshing action of the driven gear 706 and the tooth groove 703, the support rod 701 can extend the groove 702 to move up and down, thereby realizing the height adjustment of the rotating seat 4 and the rotating platform body 5. After adjustment, screw 712 is inserted into the insertion hole 710 and screwed into the corresponding limiting screw hole 711 to lock the drive gear 705 and improve the stability of the support rod 701 after adjustment.

[0034] When the rotation radius of the rotating platform body 5 needs to be adjusted, the rope wheel 810 is wound up by rotating the hand-tightening block 812, so that the slider 805 is pulled by the connecting rope 811 and the wedge-shaped locking block 806 is disengaged from the slot 815 and retracts into the telescopic cavity 804. Then, the diamond hole 813 on the rotating seat 4 is separated from the diamond column 803. After the rotating seat 4 is extended as needed, the corresponding diamond hole 813 is fitted into the diamond column 803. At this time, the wedge-shaped locking block 806 is squeezed and retracts into the telescopic cavity 804 and squeezes the spring 807. When the diamond column 803 is fully inserted into the diamond hole 813, the wedge-shaped locking block 806 automatically pops out under the rebound action of the spring 807 and is locked into the slot 815 on the fixing plate 814, thus realizing the locking and fixing of the rotating seat 4.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
