Description

Technical Field

[0001] The present invention relates to the technical field of industrial automation, and particularly to a special base for the installation of industrial robots. Background Art

[0002] Industrial robots, also known as manufacturing robots, originated in the early 1960s and were initially developed to meet the automation needs of the automotive manufacturing industry for large-scale, high-precision, and repetitive tasks. They are widely used in tasks such as assembly, welding, handling, and packaging on production lines, greatly improving production efficiency, reducing labor intensity, and promoting the modernization and lean production of the manufacturing industry. The installation base of industrial robots is an important infrastructure to ensure the stable operation and efficient operation of the robots. With the in-depth development of industrial automation, the requirements for the installation base of industrial robots are also increasing day by day.

[0003] However, the existing industrial robot bases have the following problems in the installation and use processes:

[0004] (1) The traditional robot base design often fails to fully consider the vibration and shaking problems generated by the robot during operation. Since industrial robots need to perform multi-axis movements frequently, including rotation, swinging, etc., these actions will generate complex and uneven force distributions on the base. Especially under high-speed or heavy-load working conditions, the generated dynamic loads often lead to loosening of the connection between the base and the robot body, thereby causing shaking and affecting the working accuracy and stability of the robot.

[0005] (2) The operation of the existing robot bases in the installation and disassembly processes is complex and time-consuming. The traditional locking mechanisms often rely on external tools or complex mechanical structures to achieve fastening, which not only increases the installation difficulty but also reduces the maintenance efficiency. Especially in production environments where robots need to be frequently replaced or the working layout needs to be adjusted, this inconvenience is particularly prominent. Summary of the Invention

[0006] In view of the above problems, the present invention proposes a special base for the installation of industrial robots, aiming to achieve stable locking of the robot by utilizing the self-gravity of the industrial robot. By cleverly designing the lever principle and the self-gravity balance system in the self-gravity locking mechanism, the surrounding pressures generated by the robot during operation can be effectively converted into tensile forces on the locking mechanism, thereby achieving the effect of getting tighter during movement. This design can not only effectively offset the vibration and shaking during the robot's operation and improve the working stability, but also greatly simplify the installation and disassembly processes and achieve fast and convenient operation.

[0007] The self-gravity clamping mechanism of the present invention converts the gravity of the robot body into a continuous pressure on the locking point through a series of precisely connected rods and limiting devices. When the robot performs actions such as rotation or swinging, the dynamic load generated will further enhance this pressure, making the locking mechanism fix the robot more firmly.

[0008] To achieve the above object, the present invention provides the following technical solution: A special base for the installation of an industrial robot, including a fixed bottom plate, a fixed platform is fixedly connected above the fixed bottom plate, and a cavity is formed inside the fixed platform for accommodating and supporting the internal mechanical structure. An integrated toolbox is provided on the side of the fixed platform for easy storage and access of maintenance tools. A workbench is provided on one side of the top of the fixed platform to provide an operating space for the operator. It is characterized in that a self-gravity locking and clamping device is provided in the cavity of the fixed platform, and the self-gravity locking and clamping device is fixedly connected to the fixed bottom plate, and stable clamping is achieved through self-gravity without an additional power source.

[0009] Preferably, the self-gravity locking and clamping device includes a self-gravity locking mechanism and a self-gravity clamping mechanism.

[0010] These two mechanisms work together. First, the position is fixed by the self-gravity locking mechanism, and then the industrial robot is firmly clamped by the self-gravity clamping mechanism.

[0011] Preferably, the self-gravity locking mechanism includes a load-bearing column, connecting ears, a first connecting rod, a second connecting rod, a third connecting rod, a tension column, a limiting disk, and a cross-shaped tension plate;

[0012] The load-bearing column is cylindrical, the bottom end of the load-bearing column is fixedly connected to the fixed bottom plate, two symmetrically arranged connecting ears are fixedly connected to both sides of the top end of the load-bearing column, one end of the first connecting rod is rotatably connected to the connecting ear, and the other end is rotatably connected to one end of the second connecting rod. A third connecting rod is vertically fixedly connected to the side of the second connecting rod close to the load-bearing column. A cylindrical tension column is vertically fixedly connected to the upper end surface of the end of the third connecting rod close to the load-bearing column. A disk-shaped limiting disk is fixedly connected to the top end of the tension column. The other two sides of the bottom end of the load-bearing column are arranged the same as the two sides of the top end. A cross-shaped tension plate is arranged above the load-bearing column, and the four end points of the cross-shaped tension plate are respectively sleeved on the tension columns.

[0013] These components form a mechanical structure, and through self-gravity, the connecting rods and the tension column act on each other, and finally a stable locking effect is achieved through the cross-shaped tension plate. The load-bearing column serves as a support, the connecting ears and the connecting rods transmit force, and the tension column and the limiting disk control the degree of locking to prevent over-locking.

[0014] Preferably, the cross-sectional area of the limiting disk is larger than the cross-sectional area of the tension column.

[0015] This design can ensure that the tension column will not slip out of the limit plate when stressed, increasing the reliability of locking.

[0016] Preferably, the self-gravity clamping mechanism includes a fourth connecting rod, a fifth connecting rod, a sixth connecting rod, a mounting seat, bolt holes and a clamping plate;

[0017] One end of the fourth connecting rod is rotatably connected to the second connecting rod, and the other end is rotatably connected to the fifth connecting rod. The other end of the fifth connecting rod is rotatably connected to the sixth connecting rod. The other end of the sixth connecting rod is rotatably connected to the connecting block. The connecting block is fixedly connected to the center position on one side of the bottom of the mounting seat. The mounting seat is located above the cross-shaped tension plate. The centers around the bottom of the mounting seat are respectively fixedly connected to the connecting block. The top of the fourth connecting rod is fixedly connected with a clamping plate.

[0018] These components cooperate together to distribute the clamping task of the workpiece to each connecting rod, and finally achieve stable clamping through the clamping plate. The design of the mounting seat facilitates adjustment and fixation.

[0019] Preferably, a small vacuum pump is installed at the bottom position in the inner cavity of the fixed table.

[0020] The small vacuum pump can effectively adsorb dust and fine particles in the inner cavity of the fixed table, keeping the internal environment of the inner cavity of the fixed table clean.

[0021] Preferably, bolt holes are provided at the middle positions around the top of the mounting seat.

[0022] The industrial robot base is tightly connected to the base through bolts, dispersing the stress generated by the robot base on the base, and providing an additional fixed insurance method.

[0023] Preferably, the clamping plate is provided with anti-slip rubber.

[0024] The design of the anti-slip rubber can increase the friction between the clamping plate and the workpiece, prevent the workpiece from sliding during the clamping process, and improve the safety and stability of clamping.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] In the present invention, through the self-gravity locking mechanism, the gravity of the industrial robot itself can be fully utilized to achieve stable locking during its working process. Even when the robot generates vibrations and shakes under high speed, heavy load or frequent movement, this mechanism can, through its unique structural design, convert these dynamic loads into additional tensile forces on the locking points, thereby enhancing the locking effect, effectively avoiding loosening between the robot base and the body, and significantly improving the working stability.

[0027] After long-term use, traditional robot bases often require frequent maintenance and adjustment due to the influence of vibration and shaking. The self-gravity clamping mechanism in the present invention is simply designed and easy to operate. By utilizing the gravity of the robot itself as the clamping power, rapid installation and disassembly can be achieved without additional installation tools or complex operation steps. This not only improves production efficiency but also reduces maintenance costs, and is especially suitable for production environments where robots need to be frequently replaced or the work layout needs to be adjusted. In addition, its simple and reliable design also reduces the possibility of failures, further improving the stability and reliability of the production line.

[0028] 3. The present invention integrates a toolbox in the base, providing a convenient space for maintenance personnel to store and access tools, and can also store key spare parts such as backup batteries. When the robot malfunctions or requires routine maintenance, the repair work can be quickly completed directly through the toolbox integrated in the base, greatly shortening the downtime and improving production efficiency; the small vacuum pump can effectively adsorb dust and fine particles in the inner cavity of the fixed table, keeping the internal environment of the inner cavity of the fixed table clean. This is of great significance for maintaining the long-term stable operation of the robot and extending its service life. It enables the base to adapt to more complex and changeable working environments, making the base of the present invention have stronger adaptability and expandability.

Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figures 1-5 , a special base for industrial robot installation of the present invention includes a fixed bottom plate 1, and a fixed table 2 is fixedly connected above the fixed bottom plate 1. A cavity is formed inside the fixed table 2, an integrated toolbox 3 is arranged on the side, and a workbench 4 is arranged on one side of the top end. A self-gravity locking clamping device 5 is arranged in the cavity inside the fixed table 2, and the self-gravity locking clamping device 5 is fixedly connected to the fixed bottom plate 1.

[0038] In a specific embodiment, the self-gravity locking clamping device 5 includes a self-gravity locking mechanism 51 and a self-gravity clamping mechanism 52.

[0039] In a specific embodiment, the self-gravity locking mechanism 51 includes a load-bearing column 511, a connecting ear 512, a first connecting rod 513, a second connecting rod 514, a third connecting rod 515, a tension column 516, a limit disc 517 and a cross-shaped tension plate 518.

[0040] The load-bearing column 511 is cylindrical. The bottom end of the load-bearing column 511 is fixedly connected to the fixed bottom plate 1. On both sides of the top end of the load-bearing column 511, connecting ears 512 are symmetrically and fixedly connected. One end of the first connecting rod 513 is rotatably connected to the connecting ear 512, and the other end is rotatably connected to one end of the second connecting rod 514. On the side of the second connecting rod 514 close to the load-bearing column 511, a third connecting rod 515 is vertically and fixedly connected. On the upper end surface of the end of the third connecting rod 515 close to the load-bearing column 511, a cylindrical tension column 516 is vertically and fixedly connected. The top end of the tension column 516 is fixedly connected with a disc-shaped limit disc 517. The other two sides of the bottom end of the load-bearing column 511 are the same as the two sides of the top end. Above the load-bearing column 511, a cross-shaped tension plate 518 is arranged. The four endpoints of the cross-shaped tension plate 518 are respectively sleeved on the tension columns 516.

[0041] Among them, the cross-shaped tension plate 518 can be replaced with other tension facilities such as springs according to needs to meet different usage requirements. The design of the cross-shaped tension plate 518 allows it to be replaced according to different application requirements. For example, if greater elasticity or different mechanical properties are required, the cross-shaped tension plate 518 can be replaced with a spring or a pneumatic device of appropriate specifications. In addition, in order to monitor the stability of the base in real time, a pressure sensor or a level sensor can be integrated on the cross-shaped tension plate. These sensors can detect the horizontal state of the base and the pressure received, ensuring the accuracy of the robot installation and the safety during the operation.

[0042] In a specific embodiment, the self-gravity clamping mechanism 52 includes a fourth connecting rod 521, a fifth connecting rod 522, a sixth connecting rod 523, a mounting seat 524, a bolt hole 525, and a clamping plate 526.

[0043] One end of the fourth connecting rod 521 is rotatably connected to the second connecting rod 514, and the other end is rotatably connected to the fifth connecting rod 522. The other end of the fifth connecting rod 522 is rotatably connected to the sixth connecting rod 523. The other end of the sixth connecting rod 523 is rotatably connected to a connecting block. The connecting block is fixedly connected to the center position of one side of the bottom of the mounting seat 524. The mounting seat 524 is located above the cross-shaped tension plate 518. The centers of the four peripheries of the bottom of the mounting seat 524 are respectively fixedly connected to the connecting block. The top end of the fourth connecting rod 521 is fixedly connected with a clamping plate 526.

[0044] Among them, the clamping plate 526 can be replaced according to needs. It is provided with protrusions corresponding to the grooves on the robot base to ensure the stable connection between the clamping mechanism and the robot base. In addition, anti-slip rubber can also be set on the clamping plate 526 to improve the clamping effect.

[0045] The replacement design of the clamping plate 526 enables the base to adapt to industrial robots of different models and specifications. The protrusions designed on the clamping plate correspond to the grooves on the robot base, ensuring the precise alignment and stable connection between the clamping plate 526 and the robot base. This design can effectively prevent the robot from shifting due to vibration or other external force factors.

[0046] In a specific embodiment, the integrated toolbox 3 can be configured according to the specific requirements of the industrial robot. It provides a convenient space for maintenance personnel to store and access tools, and can also store key spare parts such as spare batteries. When the robot fails or requires routine maintenance, maintenance personnel no longer need to search for tools and spare parts everywhere. They can directly complete the repair work quickly through the toolbox integrated in the base, greatly shortening the downtime and improving production efficiency. The interior of the toolbox 3 can contain various maintenance tools, such as wrenches, screwdrivers, etc., as well as spare parts such as spare batteries and circuit boards. The design of the toolbox should consider ease of use and safety to ensure that the tools and spare parts are not damaged during transportation and storage.

[0047] In a specific embodiment, bolt holes 525 are provided around the top of the mounting seat 524. These bolt holes are used to fix the robot or other equipment to the mounting seat. The position and size of the bolt holes 525 should be designed according to the installation requirements of the robot to ensure the simplicity and firmness of the installation.

[0048] In a specific embodiment, a small vacuum pump is installed at the bottom position in the inner cavity of the fixed table 2.

[0049] Integrating a small vacuum pump in the base enhances the cleaning ability and expandability of the base. The small vacuum pump can effectively adsorb dust and tiny particles in the inner cavity of the fixed table, keeping the internal environment of the inner cavity of the fixed table clean. This is of great significance for maintaining the long-term stable operation of the robot and extending its service life. In addition, the integration of the vacuum pump also enables the base to adapt to more complex and changeable working environments. By integrating the toolbox and the small vacuum pump, the base of the present invention has stronger adaptability and expandability. The toolbox and the vacuum pump, as modular components, can be configured and upgraded according to actual needs to meet the requirements of different working environments and production tasks.

[0050] The side toolbox 3 of the fixed table 2 can be easily opened, facilitating the operator to access tools and spare parts. At the same time, the replacement design of the clamping plate 526 and the cross-shaped tension plate 518 makes the maintenance of the base simpler and faster.

[0051] Through the above embodiments, the special base of the present invention can meet the requirements of various industrial applications, improve the installation efficiency and stability of industrial robots, reduce the maintenance cost at the same time, and enhance the overall production efficiency and safety.

[0052] Specific working principle:

[0053] The fixed base plate 1 serves as the foundation of the entire base, providing stable support for the entire structure. The fixed base plate 1 is fixedly connected to the ground to ensure the stability and reliability of the entire base; the fixed platform 2 is located above the fixed base plate 1, and a cavity is formed inside. An integrated toolbox 3 is provided on the side of the fixed platform 2 for storing maintenance tools, spare batteries, etc., facilitating daily maintenance and quick replacement in case of emergencies; a self-gravity locking and clamping device 5 is provided in the internal cavity of the fixed platform 2, and this device is mainly composed of a self-gravity locking machine 51 and a self-gravity clamping mechanism 52;

[0054] When the industrial robot is placed on the mounting seat 524, the self-gravity locking mechanism 51 starts to work. First, the load-bearing column 511 serves as a support point, and the force is transmitted to the second connecting rod 514 through the connecting ear 512 and the first connecting rod 513. The second connecting rod 514 then interacts with the cross-shaped tension plate 518 (or a tension device such as a spring) through the third connecting rod 515 and the tension column 516 to generate a predetermined pressure to ensure that the industrial robot is firmly clamped.

[0055] At the same time, the self-gravity clamping mechanism 52 also starts to work. The fourth connecting rod 521 moves according to the position change of the second connecting rod 514, and then drives the fifth connecting rod 522 and the sixth connecting rod 523. Finally, the protrusions on the clamping plate 526 are tightly fitted with the grooves on the base of the industrial robot to achieve stable clamping. At the same time, the base of the industrial robot is further fixed through the bolt holes 525 on the mounting seat 524.

[0056] When the self-gravity locking mechanism 51 and the self-gravity clamping mechanism 52 work simultaneously, through the interaction of the limit disc 517 and the tension column 516, the cross-shaped tension plate 518 or a tension device such as a spring generates a predetermined pressure, thereby firmly clamping the industrial robot on the base; a pressure sensor or a level sensor can also be provided on the cross-shaped tension plate 518 to monitor the operating state of the base in real time, including the magnitude of the clamping force and the levelness of the base. So as to timely adjust the clamping force or perform level adjustment to ensure the stability and safety of the installation of the industrial robot.

[0057] Through the coordinated work of the self-gravity locking mechanism 51 and the self-gravity clamping mechanism 52, a stable and reliable support and installation platform is provided for the industrial robot, thus meeting the diverse needs of the industrial site.

[0058] The above is only the preferred solution of the present invention, and is not used as a further limitation of the present invention. All equivalent changes made by using the content of the specification and drawings of the present invention are within the protection scope of the present invention.
