Description

Technical Field

[0001] This utility model relates to the field of industrial robot component design, specifically to a factory robot chassis structure. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] Industrial robots are multi-jointed manipulators or multi-degree-of-freedom machines widely used in industrial fields. They possess a certain degree of automation and can perform various industrial processing and manufacturing functions using their own power and control capabilities. Some robots are mainly used for material gripping and handling to complete assembly line processing work, replacing manual labor in handling tasks. Because industrial robots are devices for precision operations, they need to maintain relative stability during transportation to reduce rigid deformation of their bottom or other parts. Otherwise, it may cause dimensional errors during subsequent factory installation, affecting the overall operation. In current transportation processes, they are generally installed on corresponding rubber pads to reduce rigid forces during transportation and provide some cushioning. However, during placement or long-term transportation, the rubber pads are prone to tilting under prolonged unilateral force. At the same time, the robot base is subjected to static influence for a long time, resulting in irreversible deformation. This causes dimensional errors during subsequent factory installation. Furthermore, after deformation, significant swaying will occur during subsequent transportation, which may cause the robot to collide with other parts, causing damage, or even tip over and potentially destroy the robot. Utility Model Content

[0004] The main purpose of this utility model is to provide a chassis structure for a factory robot.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A factory robot chassis structure includes a support box, a support column connected to the support box, and a support platform for supporting the robot connected to the top of the support column via a ball joint. Multiple support mechanisms connected to the support box are arranged around the support column, and these support mechanisms support and adjust the support platform. Each support mechanism includes multiple pairs of support units rotatably connected to the support platform. Each pair of support units includes two opposing support sleeves located on opposite sides of the support box. A slidable movable column is sealed inside each support sleeve, and the top of the movable column engages with the support platform. An adjustment component is also provided inside the support platform, communicating with each pair of support sleeves. The adjustment component adjusts according to external forces to balance the pressure between the two support sleeves. A series assembly is also provided inside the support box, adjusting its internal pressure to ensure the support platform ultimately reaches a horizontal state. The support sleeves, adjustment components, and series assembly are all filled with liquid.

[0006] Furthermore, the adjustment assembly includes a guide pipe, which is connected to the bottom of one of a pair of support sleeves. The support platform is also provided with multiple transfer chambers, and one end of the guide pipe is connected to one of the transfer chambers. It also includes two hydraulic cylinders symmetrically arranged in the support platform, which are corresponding to the two support sleeves. The moving end of the hydraulic cylinder is connected to a counterweight block located in the support platform. A transmission rod is fixedly connected between the opposing counterweight blocks. The liquid inlet end of the hydraulic cylinder is connected to a liquid inlet pipe, which is connected to the corresponding transfer chamber. After the hydraulic cylinder on one side is filled with liquid, it drives the counterweight block on one side to move away from the center of gravity at this time and drives the counterweight block on the other side to move in the same direction.

[0007] Furthermore, the series assembly includes a second guide tube connected to the bottom of one of the support sleeves of a pair of support units, and the other end of the second guide tube is connected to an energy dissipation unit that converts mechanical energy into internal energy, thereby reducing the mechanical energy in the device.

[0008] Furthermore, the energy-consuming unit includes a damper located inside the support box, one side of which is connected to the second guide pipe; it also includes a storage tank connected to the support box, the storage tank being equipped with multiple resetters, the other end of which is fixedly connected to a movable plate located inside the storage tank. The movable plate is slidably disposed inside the storage tank and is sealed to the storage tank. The movement of the movable plate changes the volume of the liquid stored in the storage tank, performing temporary storage and buffering of the liquid. A series pipe connected to the damper is connected to one side of the storage tank, and an impact pipe is connected to the top of the storage tank. One end of the impact pipe is connected to the top of the support sleeve corresponding to the second guide pipe. During the operation of the damper, the damping fluid reduces the impact and converts mechanical energy into internal energy.

[0009] Furthermore, a partition plate for space division is provided in the middle of the support box, and a supplementary pipe extending to the outside of the support box is connected to one side of the storage tank.

[0010] Furthermore, a limiting sleeve is fixedly connected to the bottom of the support platform, and a connecting rod that is rotatably connected to the outer side of the limiting sleeve is rotatably connected to the movable column.

[0011] The beneficial effects of this utility model are reflected in:

[0012] This invention utilizes the energy conversion through compression impact and damping to achieve buffering during the swinging process, reducing the overall impact on the robot and ensuring the stability of the device during transportation. Furthermore, through fluid transfer and air pressure equalization, the support platform is kept in a horizontal state, thus preventing rigid tilting and unnecessary damage to the robot during transportation or placement. This improves the stability of the device during transportation and placement, ensuring the safety and stability of the robot. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the utility model, and not all of them. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of the utility model without creative effort are within the scope of protection of the utility model.

[0020] Example: See Figures 1 to 3 ;

[0021] This utility model discloses a factory robot chassis structure, including a support box 01, a support column 07 connected to the support box 01, and a support platform 04 for supporting the robot connected to the top of the support column 07 via a ball joint. Multiple support mechanisms connected to the support box 01 are arranged around the support column 07. The support mechanisms support and adjust the support platform 04, and the support column 07 provides the main intermediate force support for the support platform 04. The support mechanisms drive the support platform 04 to tend towards a horizontal state when bearing gravity, ensuring the safety and stability of the robot during transport.

[0022] The support mechanism includes multiple pairs of support units rotatably connected to the support platform 04. Each pair of support units includes two opposing support sleeves 02, located on opposite sides of the support box 01. A slidable movable column 06 is sealed within each support sleeve 02. The top of the movable column 06 engages with the support platform 04. Tilting the support platform 04 causes the corresponding movable column 06 on one side to descend and the movable column 06 on the other side to rise, thus allowing the liquid within the support sleeve 02 to flow. An adjustment component is also provided within the support platform 04, connected to the two support sleeves 02 in each pair. The adjustment component receives the liquid transmitted from the support sleeves 02, performs corresponding adjustments, and balances the pressure between the two support sleeves 02, providing a buffer adjustment for the position of the support platform 04. A series assembly is also provided within the support box 01, adjusting its internal pressure to ensure the support platform 04 ultimately reaches a horizontal state. The support sleeves 02, adjustment component, and series assembly are all filled with liquid, which transmits force to achieve the movement at each position.

[0023] The adjustment assembly includes a guide pipe 12 connected to the bottom of one of the pair of support sleeves 02. The guide pipe 12 is connected to the bottom of one of the support sleeves 02. The support platform 04 also has multiple transfer chambers 16. One end of the guide pipe 12 is connected to one of the transfer chambers 16. Two hydraulic cylinders 11 are symmetrically arranged within the support platform 04, corresponding to the two support sleeves 02. The moving end of each hydraulic cylinder 11 is connected to a counterweight 09 located within the support platform 04. A transmission rod 08 is fixedly connected between opposing counterweights 09. The inlet end of each hydraulic cylinder 11 is connected to an inlet pipe 18, which is connected to the corresponding transfer chamber 16. The hydraulic cylinder 11 has multiple transfer chambers 16 within the support platform 04. After cylinder 11 is filled with liquid, the counterweight 09 on one side is moved, which in turn moves the counterweight 09 on the other side, compressing the cylinder 11 on the other side and causing the liquid to flow into the transfer chamber 16 on the other side. The liquid is then transferred through the guide pipe 12, the transfer chamber 16, and the corresponding inlet pipe 18, allowing the liquid to enter the corresponding cylinder 11. The moving end of the cylinder 11 is then pushed to move, thereby moving the counterweight 09 and the transfer rod 08, further compressing the cylinder 11 on the other side, and allowing the liquid to enter the transfer chamber 16 for liquid transfer. The movement of the counterweight 09 allows the center of gravity to move in the opposite direction of the applied force, thus stabilizing the center of gravity and preventing tilting or bending due to gravity.

[0024] A limiting sleeve 05 is fixedly connected to the bottom of the support platform 04. A connecting rod that is rotatably connected to the moving column 06 is rotatably connected to the outside of the limiting sleeve 05. Through the connection between the limiting sleeve 05 and the limiting rod, the support platform 04 and the moving column 06 can be tilted at a certain angle to ensure subsequent adjustment.

[0025] The series assembly includes a flow guide tube 17 connected to the bottom of one of the support sleeves 02 in a pair of support units. The other end of the flow guide tube 17 is connected to an energy dissipation unit, which converts mechanical energy into internal energy to reduce the mechanical energy in the device.

[0026] The energy-consuming unit includes a damper 22 located inside the support box 01. One side of the damper 22 is connected to the second guide pipe 17. It also includes a storage tank 14 connected to the support box 01. Multiple resetters 26 are installed inside the storage tank 14. The other end of the resetter 26 is fixedly connected to a movable piece 15 located inside the storage tank 14. The movement of the movable piece 15 changes the volume of low-boiling-point liquid that can be stored in the storage tank 14. A series pipe connected to the damper 22 is connected to one side of the storage tank 14. An impact pipe 13 is connected to the top of the storage tank 14. One end of the impact pipe 13 is connected to the top of the support sleeve 02 corresponding to the second guide pipe 17. The storage tank 14 receives the liquid transmitted from the damper 22. After the liquid enters the storage tank 14, it is buffered and stored to reduce the impact. The resetter 26 can eventually make the movable piece 15 return to its original position, so that the liquid on both sides is balanced, thereby ensuring the level of the support platform 04.

[0027] The support box 01 is also equipped with a partition plate 24 for space division in the middle. The storage tank 14 is also connected to a supplementary pipe extending to the outside of the support box 01 on one side. The partition plate 24 divides the space to ensure space for each device.

[0028] Furthermore, the meaning of "and / or" throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, if the utility model embodiments involve descriptions of "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. Furthermore, "multiple" refers to two or more. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.
