Description

Technical Field

[0001] The invention relates to the technical field of industrial automation, and in particular to a special base for installing an industrial robot. Background Art

[0002] Industrial robots, also known as manufacturing robots, originated in the early 1960s to meet the automotive manufacturing industry's demand for large-scale, high-precision, repetitive work automation. They are widely used in assembly, welding, handling, packaging and other tasks on the production line, greatly improving production efficiency, reducing labor intensity, and promoting the modernization and lean production of the manufacturing industry. The industrial robot mounting base is an important infrastructure to ensure the stable operation and efficient operation of the robot. With the in-depth development of industrial automation, the requirements for industrial robot mounting bases are also increasing.

[0003] However, the industrial robot base in the prior art has the following problems during installation and use: (1) Traditional robot base designs often fail to fully consider the vibration and shaking problems generated by the robot during operation. Since industrial robots need to frequently perform multi-axis movements, including rotation and swinging, these movements will produce complex and uneven force distribution on the base. Especially under high-speed or heavy-load conditions, the dynamic loads generated often cause the connection between the base and the robot body to loosen, which in turn causes shaking, affecting the robot's working accuracy and stability.

[0004] (2) The robot base in the prior art is complex and time-consuming to install and disassemble. Traditional locking mechanisms often rely on external tools or complex mechanical structures to achieve fastening, which not only increases the difficulty of installation but also reduces maintenance efficiency. This inconvenience is particularly prominent in production environments where robots need to be frequently replaced or work layouts need to be adjusted. Summary of the invention

[0005] In view of the above problems, the present invention proposes a special base for installing an industrial robot, which aims to achieve stable locking of the robot by utilizing the gravity of the industrial robot itself. The self-gravity locking mechanism cleverly designs the lever principle and the self-gravity balance system, so that the surrounding pressure generated by the robot during work can be effectively converted into a pulling force on the locking mechanism, thereby achieving the effect of tightening the robot as it moves. This design can not only effectively offset the vibration and shaking of the robot during work and improve the working stability, but also greatly simplify the installation and disassembly process, and realize fast and convenient operation.

[0006] The self-gravity clamping mechanism of the present invention converts the gravity of the robot body into continuous pressure on the locking point through a series of precisely connected rods and limit devices. When the robot rotates or swings, the dynamic load generated will further enhance this pressure, allowing the locking mechanism to fix the robot more firmly.

[0007] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: A special base for installing an industrial robot, comprising a fixed base plate, a fixed platform fixedly connected to the top of the fixed base plate, and a cavity formed inside the fixed platform for accommodating and supporting the internal mechanical structure. An integrated tool box is provided on the side of the fixed platform to facilitate the storage and retrieval of maintenance tools. A workbench is provided on one side of the top of the fixed platform to provide an operating space for operators. It is characterized in that a self-gravity locking clamping device is provided in the internal cavity of the fixed platform, and the self-gravity locking clamping device is fixedly connected to the fixed base plate, and stable clamping is achieved by self-gravity without the need for an additional power source.

[0008] Preferably, the self-gravity locking and clamping device includes a self-gravity locking mechanism and a self-gravity clamping mechanism.

[0009] These two mechanisms work together to first fix the position through the self-gravity locking mechanism, and then firmly clamp the industrial robot through the self-gravity clamping mechanism.

[0010] Preferably, the self-gravity locking mechanism comprises a load-bearing column, a connecting ear, a first connecting rod, a second connecting rod, a third connecting rod, a tension column, a limit plate and a cross-shaped tension plate; The load-bearing column is cylindrical, and the bottom end of the load-bearing column is fixedly connected to the fixed bottom plate, and connecting ears are symmetrically fixedly connected on both sides of the top 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. The second connecting rod is vertically fixedly connected to a third connecting rod on a side close to the load-bearing column, and a cylindrical tension column is vertically fixedly connected to the upper end surface of one end of the third connecting rod close to the load-bearing column. A disc-shaped limiting plate is fixedly connected to the top of the tension column, and the other two sides of the bottom end of the load-bearing column are arranged in the same manner as the two sides of the top end. A cross-shaped tension plate is arranged above the load-bearing column, and the four ends of the cross-shaped tension plate are respectively mounted on the tension column.

[0011] These components form a mechanical structure, which makes the connecting rod and the tension column interact with each other through self-gravity, and finally achieves a stable locking effect through the cross-shaped tension plate. The load-bearing column serves as support, the connecting ear and the connecting rod transmit force, and the tension column and the limit plate control the degree of locking to prevent over-tightening.

[0012] Preferably, the cross-sectional area of ​​the limiting plate is larger than the cross-sectional area of ​​the tension column.

[0013] This design can ensure that the tension column will not slip out of the limit plate when subjected to force, thereby increasing the reliability of locking.

[0014] Preferably, the self-gravity clamping mechanism comprises a fourth connecting rod, a fifth connecting rod, a sixth connecting rod, a mounting seat, a bolt hole and a clamping plate; 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 of 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 blocks, and a splint is fixedly connected to the top of the fourth connecting rod.

[0015] These components work together to distribute the clamping task of the workpiece to the individual connecting rods and ultimately achieve a secure clamping via the clamping plate. The design of the mounting base allows for easy adjustment and fixing.

[0016] Preferably, a small vacuum pump is installed at the bottom of the inner cavity of the fixing table.

[0017] The small vacuum pump can effectively absorb dust and tiny particles in the cavity of the fixed table, and keep the internal environment of the cavity of the fixed table clean.

[0018] Preferably, bolt holes are provided at the middle positions around the top of the mounting seat.

[0019] The industrial robot base is tightly connected to the base through bolts, which disperses the stress generated by the robot base on the base and provides an additional fixing and insurance method.

[0020] Preferably, the clamping plate is provided with anti-slip rubber.

[0021] The anti-slip rubber design can increase the friction between the clamping plate and the workpiece, preventing the workpiece from sliding during the clamping process and improving the safety and stability of the clamping.

[0022] Compared with the prior art, the present invention has the following beneficial effects: The self-gravity locking mechanism of the present invention can fully utilize the gravity of the industrial robot itself to achieve stable locking during the working process. Even if the robot vibrates and shakes under high speed, heavy load or frequent movement, the mechanism can convert these dynamic loads into additional pulling force on the locking point through its unique structural design, thereby enhancing the locking effect, effectively preventing looseness between the robot base and the body, and significantly improving working stability.

[0023] After long-term use, the traditional robot base often needs frequent maintenance and adjustment due to vibration and shaking. The self-gravity clamping mechanism in the present invention is simple in design and easy to operate. By using the robot's own gravity as the clamping power, quick installation and disassembly can be achieved without additional installation tools or complicated operating steps. This not only improves production efficiency, but also reduces maintenance costs, and is particularly suitable for production environments that require frequent replacement of robots or adjustment of work layouts. In addition, its simple and reliable design also reduces the possibility of failures, further improving the stability and reliability of the production line.

[0024] 3. The present invention integrates a toolbox in the base, which provides maintenance personnel with a convenient space for storing and retrieving tools, and can also store key spare parts such as backup batteries. When the robot breaks down or requires daily maintenance, the maintenance work can be quickly completed directly through the toolbox integrated in the base, which greatly shortens the downtime and improves production efficiency; the small vacuum pump can effectively absorb dust and tiny particles in the cavity of the fixed table to keep the internal environment of the 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. The base can adapt to more complex and changeable working environments, making the base of the present invention more adaptable and expansible. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 5 The present invention discloses a special base for installing an industrial robot, comprising a fixed base plate 1, and a fixed platform 2 is fixedly connected to the top of the fixed base plate 1. A cavity is formed inside the fixed platform 2, an integrated tool box 3 is arranged on the side, and a workbench 4 is arranged on the top side. A self-gravity locking clamping device 5 is arranged in the internal cavity of the fixed platform 2, and the self-gravity locking clamping device 5 is fixedly connected to the fixed base plate 1.

[0030] In a specific embodiment, the self-gravity locking and clamping device 5 includes a self-gravity locking mechanism 51 and a self-gravity clamping mechanism 52 .

[0031] 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 limiting plate 517 and a cross-shaped tension plate 518 .

[0032] The load-bearing column 511 is cylindrical, and the bottom end of the load-bearing column 511 is fixedly connected to the fixed base plate 1. The top two sides of the load-bearing column 511 are symmetrically fixedly connected with connecting ears 512. 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. The second connecting rod 514 is vertically fixedly connected to the side close to the load-bearing column 511 with a third connecting rod 515. The upper end surface of one end of the third connecting rod 515 close to the load-bearing column 511 is vertically fixedly connected with a cylindrical tension column 516. The top of the tension column 516 is fixedly connected with a disc-shaped limiting plate 517. The other two sides of the bottom end of the load-bearing column 511 are arranged in the same way as the two sides of the top. A cross-shaped tension plate 518 is arranged above the load-bearing column 511, and the four ends of the cross-shaped tension plate 518 are respectively mounted on the tension column 516.

[0033] Among them, the cross-shaped tension plate 518 can be replaced with other tension facilities such as springs as needed 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 elastic force or different mechanical properties are required, the cross-shaped tension plate 518 can be replaced with a spring or 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 it is subjected to, ensuring the accuracy of the robot installation and safety during operation.

[0034] 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 .

[0035] 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 sides of the bottom of the mounting seat 524 are respectively fixedly connected to the connecting blocks. The top of the fourth connecting rod 521 is fixedly connected with a clamping plate 526.

[0036] The clamping plate 526 can be replaced as needed, and is provided with a protrusion corresponding to the groove on the robot base to ensure a stable connection between the clamping mechanism and the robot base. In addition, the clamping plate 526 can also be provided with anti-slip rubber to improve the clamping effect.

[0037] 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 factors.

[0038] In a specific embodiment, the integrated toolbox 3 can be configured according to the specific needs of the industrial robot. It provides maintenance personnel with a convenient space for storing and accessing tools, and can also store key spare parts such as spare batteries. When the robot breaks down or requires daily maintenance, maintenance personnel no longer need to look for tools and spare parts everywhere, and can quickly complete maintenance work directly through the toolbox integrated in the base, which greatly shortens downtime and improves production efficiency. The toolbox 3 can contain a variety of maintenance tools, such as wrenches, screwdrivers, spanners, etc., as well as spare parts such as spare batteries and circuit boards. The design of the toolbox should take into account ease of use and safety to ensure that tools and spare parts are not damaged during transportation and storage.

[0039] In a specific embodiment, bolt holes 525 are arranged around the top of the mounting seat 524, and 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 ease and firmness of installation.

[0040] In a specific embodiment, a small vacuum pump is installed at the bottom of the inner cavity of the fixing platform 2 .

[0041] Integrating a small vacuum pump in the base enhances the cleaning ability and expansibility of the base. The small vacuum pump can effectively absorb dust and tiny particles in the cavity inside the fixed table, and keep the internal environment of the cavity inside 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 expansibility. As modular components, the toolbox and the vacuum pump can be configured and upgraded according to actual needs to meet the needs of different working environments and production tasks.

[0042] The side tool box 3 of the fixed platform 2 can be easily opened, which is convenient for operators 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.

[0043] Through the above implementation cases, the special base of the present invention can meet the needs of various industrial applications, improve the installation efficiency and stability of the industrial robot, while reducing maintenance costs and improving overall production efficiency and safety.

[0044] Specific working principle: The fixed base plate 1 serves as the base of the entire base and provides 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 tool box 3 is provided on the side of the fixed platform 2 for storing maintenance tools, spare batteries, etc., to facilitate daily maintenance and rapid replacement in emergency situations; a self-gravity locking and clamping device 5 is provided in the internal cavity of the fixed platform 2, and the device is mainly composed of a self-gravity locking machine 51 and a self-gravity clamping mechanism 52; 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 acts as a support point and transmits force 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 tension facilities such as springs) 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.

[0045] 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, thereby driving the fifth connecting rod 522 and the sixth connecting rod 523, and finally making the protrusion on the clamping plate 526 closely match the groove 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 hole 525 on the mounting seat 524.

[0046] When the self-gravity locking mechanism 51 and the self-gravity clamping mechanism 52 work simultaneously, the interaction between the limit plate 517 and the tension column 516 causes the cross-shaped tension plate 518 or tension facilities such as springs to generate 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 status of the base in real time, including the size of the clamping force and the levelness of the base, so as to adjust the clamping force or perform leveling in time to ensure the stability and safety of the installation of the industrial robot.

[0047] 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, thereby meeting the diverse needs of the industrial site.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to be a further limitation of the present invention. All equivalent changes made using the contents of the present specification and drawings are within the protection scope of the present invention.
