Description

Technical Field

[0001] This utility model relates to the field of leveling technology, and specifically to a leveling component. Background Technology

[0002] Precision equipment requires a high degree of levelness on the worktable, and the worktable needs to be leveled during installation.

[0003] The leveling method for a leveling platform generally involves selecting multiple positions spaced apart on the platform plane, setting up a drive module at each position, and adjusting the height of the platform at the corresponding position through the cooperation of multiple drive modules to achieve platform leveling.

[0004] In related technologies, a separate power unit is usually required for each drive module, which results in high equipment costs. Utility Model Content

[0005] Based on the above description, this utility model provides a leveling component to solve the problem that related technologies usually require a separate power device for each drive module, resulting in high equipment costs.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: This application provides a leveling component, and the technical solution adopted is as follows: A leveling component, comprising: At least three leveling mechanisms are distributed at intervals in a horizontal plane and are not on a straight line. The leveling mechanism includes a driving element and a driving structure. The driving element can move in the vertical direction. A drive mechanism includes a power unit and at least three power output components. The at least three power output components are respectively connected to the power unit through a transmission assembly. The power unit transmits power to the power output components through the transmission assembly, and the transmission assembly can disconnect the power transmission between the power unit and the power output components. Among them, at least three of the power output components correspond one-to-one with at least three of the leveling mechanisms. The drive structure connects the corresponding drive component and the power output component. The power output component outputs power and transmits it to the drive component through the drive structure to drive the drive component to move in the vertical direction.

[0007] By adopting the above configuration, at least three leveling mechanisms, each equipped with a driving component, can vertically move to adjust the height of the platform at a corresponding position, simplifying the adjustment method. A power unit and at least three power output components are configured. The power output from the power unit is transmitted to the power output components via a transmission assembly, and the power output components output power, effectively dividing the power from one power unit into at least three output powers. These at least three output powers are then input one-to-one into at least three leveling mechanisms, providing power to them. This means that power is supplied to at least three leveling mechanisms by a single power unit, reducing equipment costs. Furthermore, the transmission assembly can disconnect the power transmission between the power unit and the power output components, effectively severing the power transmission between the power unit and the leveling mechanisms. During actual leveling operation, the power transmission between one or more power output components and the power unit can be disconnected to transfer power to one or some leveling mechanisms, thereby allowing for individual adjustment of the platform's height at different positions to achieve the purpose of leveling the platform.

[0008] Preferably, the transmission assembly includes a clutch device, which is used to transmit the power output of the power device to the power output member, or to disconnect the power transmission between the power device and the power output member, and the power output of the power device is transmitted to at least one of the power output members to drive at least one of the driving members to move in the vertical direction.

[0009] Preferably, the power unit includes a power source and a main output component. The power source outputs power through the main output component, and the power output component is connected to the main output component through the transmission assembly. The power output of the main output component is simultaneously transmitted to at least three of the transmission assemblies.

[0010] Preferably, the transmission assembly includes an input component and a first transmission structure. The input component is connected to the main output component, and the first transmission structure connects the input component and the power output component. The first transmission structure is connected to the input component via the clutch device.

[0011] Preferably, the output component and the input component are gears that mesh with each other. The first transmission structure includes a drive wheel, a driven wheel, and a transmission component connecting the drive wheel and the driven wheel. The drive wheel is coaxial with the input component and connected to the input component through the clutch device. When the drive wheel rotates, it drives the driven wheel to rotate through the transmission component.

[0012] Preferably, the clutch device includes an electric clutch.

[0013] Preferably, the driving wheel and the driven wheel are synchronous pulleys, and the transmission component is a synchronous belt.

[0014] Preferably, the power output component is a gear.

[0015] Preferably, the drive structure includes a lead screw with a vertical axis and a second transmission structure. The drive component is threadedly connected to the lead screw and is restricted to rotate with the lead screw. The second transmission structure connects the power output component and the lead screw. The power output component outputs power to drive the lead screw to rotate through the second transmission structure.

[0016] Preferably, the second transmission structure is a gear transmission structure.

[0017] Compared with the prior art, the technical solution of this application has at least the following beneficial technical effects: 1. The leveling component of this application, comprising at least three leveling mechanisms, uses drive components, each capable of vertical movement, to adjust the height of the platform at a corresponding position, simplifying the adjustment method. It includes a power unit and at least three power output components. The power unit outputs power through a transmission assembly to the power output components, which then output power, effectively dividing the power of one power unit into at least three output powers. These three output powers are then input one-to-one into at least three leveling mechanisms, providing power to them. This single power unit powers at least three leveling mechanisms, reducing equipment costs. Furthermore, the transmission assembly can disconnect the power transmission between the power unit and the power output components, effectively disconnecting the power transmission between the power unit and the leveling mechanisms. During actual leveling operation, the power transmission between one or more power output components and the power unit can be disconnected, allowing power to be transferred to one or more leveling mechanisms, thereby enabling individual adjustment of the platform's height at different positions to achieve the purpose of leveling the platform.

[0018] 2. In the leveling assembly of this application, the transmission assembly includes a clutch device. When the clutch device is engaged, it can transmit the power output from the power unit to the power output component. When the clutch device is disengaged, the power transmission between the power unit and the power output component is disconnected. During leveling, by keeping the clutch device engaged in at least one transmission assembly, the power output from the power unit is transmitted to at least one power output component, thereby driving at least one driving component to move vertically. This allows for arbitrary adjustment of the height of one or more driving components, resulting in different lifting heights at different positions of the platform, thus achieving platform leveling.

[0019] 3. In the leveling component of this application, the power unit is provided with a total output component, and each transmission component is connected to the total output component. The total output component outputs power and transmits it to at least three first transmission structures at the same time, so that the power source outputs power to transmit it to at least three power output components at the same time, thereby enabling the power output components to output power synchronously to achieve synchronous adjustment of the height at each position of the platform, and thus achieve the height adjustment of the platform.

[0027] Reference Figure 1 As shown, this application embodiment provides a leveling component, including a drive mechanism 1 and at least three leveling mechanisms 2 that are spaced apart on a horizontal plane and not on a straight line.

[0028] Reference Figure 1 and Figure 2 As shown, the leveling mechanism 2 includes a driving component 21 and a driving structure. The driving component 21 can be vertically raised and lowered, and the driving structure is used to drive the driving component 21 to be vertically raised and lowered or to maintain it at a set height. During installation, the leveling mechanism 2 is mounted on the platform base and located below the platform. The platform is supported on the driving component 21. The height of the platform at the location of the driving component 21 is adjusted by the vertical raising and lowering of the driving component 21. At least three driving components 21 work together to achieve leveling of the platform.

[0029] Reference Figure 2 As shown, in this embodiment, a support member 26 is provided above the drive member 21, and a spring 27 is provided between the support member 26 and the drive member 21. The support member 26 is supported on the support member 26 by the spring 27, and the platform is directly supported on the support member 26 during installation. In this way, the height of the support member 26 can be adjusted by raising and lowering the drive member 21, thereby adjusting the height of the corresponding position of the platform, and the spring 27 can also play a vibration damping role.

[0030] Specifically, the driving component 21 is a cylindrical block, and the support component 26 includes a limiting block, a damping rubber block, and a support block arranged sequentially from bottom to top. Annular limiting grooves are respectively provided on the top surface of the driving component 21 and the bottom surface of the limiting block. The limiting grooves are coaxially arranged with the spring 27. Both ends of the spring 27 are respectively embedded in the limiting grooves on the driving component 21 and the limiting block, so that the spring is restricted to radial movement relative to the driving component 21 and the limiting block through the limiting grooves. The top surface of the support block is flat, and the platform is directly supported on the support block during installation. The contact area between the support block and the platform is increased through contact between the support block and the platform, thereby providing stable support for the platform. The damping rubber block further improves the vibration reduction effect.

[0031] The drive mechanism 1 is used to provide power to at least three leveling mechanisms 2 to drive the drive member 21 to rise and fall. The power output by the drive mechanism 1 is transmitted to the drive member 21 through the drive structure, thereby driving the drive member 21 to move vertically.

[0032] Reference Figure 2 As shown, the drive structure includes a vertically oriented lead screw 22 and a second transmission structure. The drive member 21 is threadedly connected to the lead screw 22 and is restricted to rotate with it. The second transmission structure connects the lead screw 22 and the drive mechanism 1. The drive mechanism 1 outputs power to drive the lead screw 22 to rotate through the second transmission structure. The rotation of the lead screw 22 causes the drive member 21 to move vertically, thus achieving height adjustment of the drive member 21 in a simple and easy-to-control manner, and it also provides a self-locking function at any height.

[0033] Reference Figure 2 As shown, specifically, the lead screw 22 is rotatably mounted on the base, and the driving component 21 is sleeved on the lead screw 22 and threadedly connected to the lead screw 22. A limiting structure is provided on the base to restrict the rotation of the driving component 21 with the lead screw 22. The limiting structure can be two vertical guide rods spaced apart, and a limiting rod located between the two guide rods is connected to the driving component 21. The two guide rods guide and limit the limiting rod, thereby restricting the rotation of the driving component 21 with the lead screw 22. The specific structure is a conventional technical means and will not be described in detail here. In this embodiment, the driving component 21 is a cylindrical block coaxially sleeved on the outside of the lead screw 22 and threadedly connected to the lead screw 22.

[0034] Reference Figure 2As shown, the second transmission structure is further a gear transmission structure, which transmits the power output from the drive mechanism 1 to the lead screw 22. Specifically, the second transmission structure includes a first transmission gear 23, a second transmission gear 24, and a first driven gear 25. The first driven gear 25 is coaxially and fixedly connected to the lead screw 22. The first transmission gear 23 and the second transmission gear 24 are coaxially and fixedly connected and rotatably mounted on the base. The second transmission gear 24 and the first driven gear 25 mesh. The drive mechanism 1 outputs power to drive the first transmission gear 23 to rotate, which in turn drives the first driven gear 25 to rotate, causing the lead screw 22 to rotate synchronously. The diameter of the second transmission gear 24 is smaller than the diameter of both the first transmission gear 23 and the first driven gear 25, achieving a reduction in power transmission to allow for slow adjustment of the height of the drive component 21, improving adjustment accuracy.

[0035] Reference Figure 1 As shown, furthermore, an encoder 3 for detecting the number of rotations of the first driven gear 25 is also provided on the base. A gear is mounted on the output shaft of the encoder 3, and this gear is connected to the first driven gear 25 via a gear transmission structure. The gear on the output shaft of the encoder 3 and the first driven gear 25 are also connected and transmitted via a gear transmission structure, specifically including a second driven gear and a third transmission gear. The second driven gear meshes with the first driven gear 25 and its diameter is smaller than that of the first driven gear 25. The third transmission gear and the second driven gear are coaxially and fixedly connected. The third transmission gear meshes with the gear on the output shaft of the encoder 3, and its diameter is smaller than both the diameter of the second transmission gear and the diameter of the gear on the output shaft of the encoder 3. This achieves power transmission between the gear on the encoder output shaft and the first driven gear, so that the number of rotations of the first driven gear 25 can be detected by the encoder.

[0036] When the first driven gear 25 rotates, the power is transmitted sequentially through the second driven gear and the third transmission gear to the gear on the output shaft of the encoder 3, thereby driving the output shaft of the encoder 3 to rotate and thus measuring the number of rotations or angle of the first driven gear 25. Combined with parameters such as the pitch of the lead screw 22, the lifting displacement of the drive component 21 can be calculated. With the help of the automatic control system, the precise adjustment and automatic control of the lifting displacement of the drive component 21 can be achieved.

[0037] Reference Figure 1 and Figure 2 As shown, the drive mechanism 1 includes a power unit and at least three power output components 11. The at least three power output components 11 are respectively connected to the power unit through a transmission assembly. The power unit transmits power to the power output components 11 through the transmission assembly, and the transmission assembly can disconnect the power transmission between the power unit and the power output components 11.

[0038] Reference Figure 1As shown, at least three power output components 11 correspond one-to-one with at least three leveling mechanisms 2, meaning the number of power output components 11 is the same as the number of leveling mechanisms 2 and they correspond one-to-one. The drive structure connects the corresponding drive component 21 and the power output component 11. The power output component 11 outputs power to the first transmission gear 23, causing the first transmission gear 23 to rotate. The power is transmitted to the drive component 21 through the second transmission gear 24, the first driven gear 25, and the lead screw 22, thereby driving the drive component 21 to move vertically up and down.

[0039] With the above configuration, the power output component 11 outputs power in at least three ways, meaning that one power unit provides power to at least three leveling mechanisms 2, thus reducing equipment costs. The transmission assembly can disconnect the power transmission between the power unit and the power output component 11. This allows for the disconnection of power transmission between one or more power output components 11 and the power unit when needed, enabling the transmission of power to one or more leveling mechanisms 2, thereby allowing for individual adjustment of the height at different positions on the platform.

[0040] Reference Figure 1 and Figure 2 As shown, specifically, the power unit includes a power source 12 and a main output component 13. The power source 12 outputs power through the main output component 13. Power output components 11 are connected to the main output component 13 via transmission components. The power output from the main output component 13 is simultaneously transmitted to at least three transmission components. Since the power source 12 outputs power to at least three power output components 11 simultaneously, the power output components 11 can synchronously output power to achieve synchronous height adjustment at various positions on the platform, thus realizing platform height adjustment control.

[0041] The transmission assembly includes a clutch device 15, which transmits power from the power unit to the power output component 11 or disconnects the power transmission between the power unit and the power output component 11. The power unit transmits power to at least one power output component 11 to drive at least one drive component 21 to move vertically. During leveling, by keeping the clutch device 15 engaged in at least one transmission assembly, the power unit transmits power to at least one power output component 11 to drive at least one drive component 21 to move vertically. This allows for arbitrary adjustment of the height of one or more drive components 21, resulting in different lifting heights at different positions of the platform, thereby achieving platform leveling.

[0042] Reference Figure 2 As shown, the transmission assembly includes an input component 14 and a first transmission structure. The input component 14 is connected to the main output component 13. The first transmission structure connects the input component 14 and the power output component 11. The first transmission structure is connected to the input component 14 through a clutch device 15.

[0043] Reference Figure 2As shown, both the output component 13 and the input component 14 are gears that mesh with each other. The first transmission structure includes a drive wheel 16, a driven wheel 17, and a transmission component 18 connecting the drive wheel 16 and the driven wheel 17. The drive wheel 16 is coaxial with the input component 14 and connected to the input component 14 through a clutch device 15. When the drive wheel 16 rotates, it drives the driven wheel 17 to rotate through the transmission component 18. Specifically, the power source 12 is a motor, which is fixed on the base during installation. The input component 14 is rotatably mounted on the base. The output component 13 is coaxially fixed with the motor output shaft. The input component 14 and the output component 13 are meshed together to transmit the motor output power to the input component 14.

[0044] When the input component 14 rotates, power can be transmitted to the drive wheel 16 via the clutch device 15, or the clutch device 15 can disconnect the power transmission between the input component 14 and the drive wheel 16, i.e., the input component 14 gear rotates freely. The clutch device 15 is an electric clutch. Specifically, in the configuration, the input component 14 and the drive wheel 16 are coaxially connected to rotating shafts. The active and driven connection ends of the clutch are connected to the rotating shafts of the input component 14 and the drive wheel 16, respectively. The clutch control end is connected to the control system. The engagement and disengagement of the clutch are actively controlled by the control system to achieve automatic control of the power transmission or disconnection between the input component 14 and the drive wheel 16.

[0045] Reference Figure 2 As shown, when the input component 14 transmits power to the drive wheel 16, the rotation of the drive wheel 16 drives the driven wheel 17 to rotate via the transmission component 18. Specifically, both the drive wheel 16 and the driven wheel 17 are synchronous pulleys, and the corresponding transmission component 18 is a synchronous belt, thus realizing the power transmission between the drive wheel 16 and the driven wheel 17.

[0046] Reference Figure 2 As shown, the power output component 11 is a gear, coaxially fixed with the driven wheel 17, and also coaxially connected to an output gear 19. The output gear 19 meshes with the first driven gear 25, and the diameter of the output gear 19 is smaller than the diameter of the first driven gear 25. This achieves a complete reduction transmission path from the motor to the first driven gear 25, thus enabling the function of controlling at least three leveling mechanisms 2 with one motor.

[0047] Specifically, during actual operation, the power source 12 motor starts and outputs power. The motor power is output through the rotation of the gear in the main output component 13, which in turn drives the input component 14 gear, which meshes with it, to rotate. If the clutch device 15 is engaged, the power from the rotation of the input component 14 gear can be transmitted to the drive wheel 16 via the clutch device 15. The rotation of the drive wheel 16 inputs power to the synchronous belt of the transmission component 18. The transmission component 18 drives the driven wheel 17 to rotate synchronously with the drive wheel 16, transmitting power to the driven wheel 17. The rotation of the driven wheel 17 drives the gear in the power output component 11, which is coaxial with it, to rotate. The rotation of the power output component 11 drives the output gear 19 to rotate, transmitting power to the first transmission gear 23, and then through the second transmission gear 24 to the first driven gear 25. The first driven gear 25 rotates, causing the lead screw 22, which is fixed coaxially with it, to rotate. When the lead screw 22 rotates, the driving component 21 does not rotate with the lead screw 22 under the restriction of the limiting rod and the guide rod, but moves along the axial direction of the lead screw 22, thus achieving the purpose of driving the driving component 21 to move vertically.

[0048] The output gear 13 has a smaller diameter than the input gear 14, achieving a first-stage reduction in the motor's output power. The output gear 19 has a smaller diameter than the first transmission gear 23, achieving a second-stage reduction in power. The second transmission gear 24 has a smaller diameter than the first driven gear 25, achieving a third-stage reduction in power. In other words, the motor's output power to the lead screw 22 undergoes three stages of reduction. This reduction in power output increases the output torque, ensuring sufficient driving force for platform lifting and leveling. The reduced power output to the first driven gear 25 allows for slow rotation of both the first driven gear 25 and the lead screw 22. The lead screw pitch is designed to be relatively small, enabling slow lifting of the drive component 21, thus allowing for slow and small-amplitude adjustments to the platform and ensuring platform leveling accuracy.

[0049] When the platform is raised and lowered as a whole, all clutches 15 are engaged, and each leveling mechanism 2 receives power input to drive the platform to rise and fall. During leveling, based on the height difference of the platform at each leveling mechanism 2, the leveling mechanism 2 corresponding to the higher position of the platform can be stopped. That is, the clutch 15 in the transmission component corresponding to the leveling mechanism 2 is disengaged, which disconnects the power transmission between the input component 14 and the drive wheel 16, and disconnects the power transmission between the motor and the leveling mechanism 2. The leveling mechanism 2 stops operating due to the lack of power input, while the leveling mechanisms 2 corresponding to other positions of the platform continue to operate, thereby achieving platform leveling.

[0050] In some embodiments, the number of leveling mechanisms 2 is set according to the platform support requirements. When at least three leveling mechanisms 2 are set, they are distributed in a circle around the vertical center line to ensure the force balance of the platform located on the at least three leveling mechanisms 2. During platform leveling, the height of the driving component 21 in each leveling mechanism 2 is controlled to ensure that each leveling mechanism 2 supports the platform and adjusts the platform to a horizontal position. In this embodiment, four leveling mechanisms 2 are illustrated, and the four leveling mechanisms 2 are distributed in a rectangular shape.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
