Description

Technical Field

[0001] This utility model relates to the field of automated processing technology, and in particular to an adjustable rotary platform mechanism. Background Technology

[0002] In existing automated equipment, the processing platform typically uses X-axis, Y-axis, and Z-axis motion platforms. Whether it's a single X-axis, Y-axis, and Z-axis platform, or a dual X-axis, Y-axis, and Z-axis platform, the workpiece is generally fixed on a slider along the Y-axis and moves back and forth, while the Z-axis is fixed on a slider along the X-axis. The working device (such as a screw fastening machine or a dispensing machine) is fixed on a slider along the Z-axis and moves up and down and left and right. However, the working device on existing processing platforms can only operate on one plane of the workpiece, resulting in low work efficiency.

[0003] To solve this problem, our company designed a rotating platform mechanism, which includes a base plate, a central shaft, a rotating plate with a positioning block at the top, a servo motor, a belt, and two pulleys. The servo motor is mounted on the base plate, and the base plate is mounted on the machine body. The rotating plate is rotatably mounted on the base plate. The upper end of the central shaft is fixedly connected to the rotating plate, and the central shaft is rotatably connected to the base plate. The two pulleys are respectively mounted on the central shaft and the output shaft of the servo motor. During operation, the servo motor works, and the cooperation of the pulleys and belt causes the central shaft to drive the rotating plate to rotate.

[0004] The pulley size of existing rotary platform mechanisms is generally matched with the belt width, making it impossible to replace belts of different widths for use according to actual conditions. Therefore, this application provides an adjustable rotary platform mechanism to meet the requirements. Utility Model Content

[0005] The purpose of this application is to provide an adjustable rotary platform mechanism to solve the technical problem that the pulleys of existing rotary platform mechanisms are limited by their size and cannot be replaced with belts of different widths as needed.

[0006] To achieve the above objectives, this application provides the following technical solution: an adjustable rotating platform mechanism, comprising a base plate, a central shaft, a rotating plate with a positioning block at its upper end, a servo motor, and a belt. The servo motor is mounted on the base plate, the base plate is mounted on the machine body, the rotating plate is rotatably mounted on the base plate, the upper end of the central shaft is fixedly connected to the rotating plate, and the central shaft is rotatably connected to the base plate. The mechanism also includes two adjustable pulleys, which are respectively mounted on the central shaft and the output shaft of the servo motor. The belt is mounted on the two adjustable pulleys, and the size of the adjustable pulleys is adjustable to accommodate belts of different widths.

[0007] In a preferred embodiment of this invention, the adjustable pulley includes an upper mounting plate on which a vertical rod is mounted at the shaft center. Multiple plate-shaped toothed rings are slidably disposed on the vertical rod in an upward and downward arrangement. A slider is disposed at the center hole of each plate-shaped toothed ring. The multiple sliders are arranged in a circle when viewed from above. Multiple movable grooves that are adapted to the sliders are disposed in a circle on the vertical rod, and the depth of the movable grooves increases in a clockwise direction.

[0008] It also includes a lower base plate that is slidably mounted on the upright. A connecting rod is fixed on the inner wall of the axial hole of the lower base plate. The connecting rod passes through the upright and extends into the inner cavity of the upright to connect with the nut. The nut is threaded onto the screw rod. The screw rod is rotatably mounted in the inner cavity of the upright. The lower end of the screw rod passes through the upright and connects to the hand grip post.

[0009] As a preferred embodiment of this invention, a positioning unit is also included to ensure the stability of the screw.

[0010] In a preferred embodiment of this invention, the positioning unit includes an L-shaped post movably disposed in the grip post and the inner cavity of the screw, and a positioning toothed ring fixed in the inner cavity of the upright. The upper end of the L-shaped post passes through the screw and is fixed with positioning teeth. A pressing post is fixed on the part of the L-shaped post located in the inner cavity of the grip post, and the end of the pressing post away from the L-shaped post passes through the grip post. The inner wall of the grip post is connected to the L-shaped post through a return spring.

[0011] In a preferred embodiment of this invention, the increase in depth of two adjacent movable slots is the same in a clockwise direction.

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] This utility model has a reasonable structure. The rotating platform mechanism is equipped with an adjustable pulley, and the multiple plate-shaped toothed rings arranged from top to bottom have a certain gap after adjustment. This can adapt to the installation of belts of different widths while ensuring that all parts of the belt can bear force, which is conducive to the stable operation of the belt.

[0014] In this invention, the increase in depth of two adjacent movable grooves is the same in the clockwise direction, which is beneficial to the uniform force on the belt and further improves the stability of belt operation. Attached Figure Description

[0023] 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.

[0024] Example: Reference Figure 1-2An adjustable rotating platform mechanism is shown, including a base plate 1, a central shaft 2, a rotating plate 3 with a positioning block at the upper end, a servo motor 4, and a belt 6. The servo motor 4 is mounted on the base plate 1, and the base plate 1 is mounted on the machine body. The rotating plate 3 is rotatably mounted on the base plate 1. The upper end of the central shaft 2 is fixedly connected to the rotating plate 3, and the central shaft 2 is rotatably connected to the base plate 1. It also includes two adjustable pulleys 5, which are respectively mounted on the central shaft 2 and the output shaft of the servo motor 4. The belt 6 is assembled on the two adjustable pulleys 5, and the size of the adjustable pulleys 5 can be adjusted to accommodate belts 6 of different widths.

[0025] As a preferred embodiment of this example, Figure 3-6 As shown, the adjustable pulley 5 includes an upper mounting plate 7 on which a vertical rod 10 is mounted at the shaft center. Multiple plate-shaped toothed rings 8 are slidably arranged on the vertical rod 10 in an upward and downward arrangement. Each plate-shaped toothed ring 8 has a slider 21 at its center hole. The multiple sliders 21 are arranged in a circle when viewed from above. Multiple movable grooves 11 that are adapted to the sliders 21 are arranged in a circle on the vertical rod 10. The depth of the movable grooves 11 increases in the clockwise direction.

[0026] It also includes a lower base plate 9 that is slidably mounted on the upright 10. A connecting rod 14 is fixed on the inner wall of the axial hole of the lower base plate 9. The connecting rod 14 passes through the upright 10 and extends into the inner cavity of the upright 10 to connect with a nut 13. The nut 13 is threaded onto a screw rod 12. The screw rod 12 is rotatably mounted in the inner cavity of the upright 10. The lower end of the screw rod 12 passes through the upright 10 and connects to a hand grip post 18.

[0027] During installation, the screw 12 can be rotated by holding the hand grip column 18. The rotation of the screw 12 will drive the lower base plate 9 to move downward. As the lower base plate 9 moves downward, multiple plate-shaped toothed rings 8 will start to move downward synchronously. When the corresponding upper plate-shaped gear 8 moves to the lowest point of the corresponding movable groove 11, it stops moving. The lower plate-shaped toothed ring 8 will continue to move downward until it stops moving at the lowest point of the corresponding movable groove 18. This allows the multiple plate-shaped toothed rings 8 set from top to bottom to have a certain gap after adjustment, which can adapt to the installation of belts of different widths and also ensure that all parts of the belt 6 can bear force, which is conducive to the stable operation of the belt 6.

[0028] As a preferred embodiment of this invention, a positioning unit is also included to ensure the stability of the screw 12.

[0029] As a preferred embodiment of this example, Figure 5As shown, the positioning unit includes an L-shaped post 17 movably disposed in the inner cavity of the grip post 18 and the screw 12, and a positioning toothed ring 19 fixed in the inner cavity of the upright post 10. The upper end of the L-shaped post 17 passes through the screw 12 and is fixed with positioning teeth 20. A pressing post 16 is fixed on the part of the L-shaped post 17 located in the inner cavity of the grip post 18, and the end of the pressing post 16 away from the L-shaped post 17 passes through the grip post 18. The inner cavity wall of the grip post 18 is connected to the L-shaped post 17 through a return spring 15.

[0030] During adjustment, hold the hand-holding column 18 and press the column 16 with your fingers to move the positioning tooth 20 out of the positioning gap of the positioning tooth ring 19. Rotate the screw 12. After adjustment, release the pressing column 16. The L-shaped column 17 returns to its original position by the elastic force of the return spring 15. The positioning tooth 20 and the positioning tooth ring 19 are inserted to form a positioning. At this time, the screw 12 cannot rotate. The positioning operation is convenient and simple. The positioning operation of the screw 12 can be completed during the adjustment process.

[0031] In a preferred embodiment of this invention, the depth of two adjacent movable slots 11 increases by the same amount in a clockwise direction.

[0032] This helps the belt 6 to be subjected to uniform force, further improving the stability of the belt 6 operation.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
