Description

Technical Field

[0001] This utility model relates to the field of hand bearing assembly equipment technology, and in particular to a cross roller bearing assembly device for robots. Background Technology

[0002] In modern machinery and engineering, cross-roller bearings are widely used in various mechanical equipment and structures due to their excellent load-carrying capacity and flexibility. Cross-roller bearings are a special type of roller bearing with rollers arranged in an X or Y pattern. Through the action of multiple rows of rollers, they can withstand large radial and axial loads in equipment, ensuring the stability and reliability of equipment operation. However, traditional manual installation methods are inefficient and prone to deviations, affecting assembly quality and the overall performance of the product.

[0003] Currently, traditional assembly equipment designs typically focus only on simplifying the assembly process, neglecting the importance of component positioning during assembly. This design flaw causes assembled bearings to fail to meet expected performance requirements, especially under high-speed operation and heavy load conditions, where these problems become more pronounced.

[0004] However, existing robotic assembly technologies have limitations in the devices used for assembling cross roller bearings. These devices cannot simultaneously and effectively limit the outer and inner rings of the bearing, resulting in insufficient precision during assembly. Because the outer and inner rings cannot be stably and accurately positioned during assembly, the bearing is prone to mispositioning during use. Furthermore, inaccurate assembly can lead to a series of problems, such as increased bearing vibration and noise, and premature wear. These issues not only affect the performance and lifespan of the bearing itself but also indirectly impact the reliability and operational efficiency of the entire robot. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a cross-roller bearing assembly device for robots. This addresses the problem that existing cross-roller bearing assembly devices for robots cannot simultaneously perform effective positioning operations on the outer and inner rings of the bearing during assembly, resulting in insufficient precision during the assembly process. Because the outer and inner rings cannot be stably and accurately positioned during assembly, the bearing is prone to positioning problems during use.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A robot cross roller bearing assembly device includes: a base, on the top of which a support assembly and an assembly assembly are provided; The inner side of the support assembly is provided with a clamping assembly, which includes a rotation drive assembly, a rotating ring, a linkage assembly, a mounting plate, a slider one, a slider two, a clamping block one, an elastic pad one, an elastic pad two, and a clamping block two. The drive assembly is located on the top of the base, and the rotating ring is located on the top of the drive assembly. The mounting plate has two sliding grooves, one and two, with the first sliding groove located outside the second sliding groove. One end of the linkage assembly is movably connected to the rotating ring. There are two sets of linkage assemblies. The other end of one set of linkage assemblies is movably connected to the slider one, and the other end of the other set of linkage assemblies is movably connected to the slider two. The slider one is slidably mounted inside the first sliding groove, and the second sliding groove is slidably mounted inside the second sliding groove. The clamping block one is fixedly mounted on the top of the slider one, the elastic pad one is fixedly mounted on the inner wall of the clamping block one, the clamping block two is fixedly mounted on the top of the slider two, and the elastic pad two is fixedly mounted on the outer wall of the clamping block two, with the clamping block one located outside the clamping block two.

[0007] Furthermore, a support leg is fixedly installed at the bottom of the base, and a foot pad is fixedly installed at the bottom end of the support leg.

[0008] Furthermore, the support assembly includes a support column, a top plate, and a connecting rod. The support column is fixedly installed on the top of the base, and the top end of the support column is fixedly connected to the top plate. One end of the connecting rod is fixedly connected to the top plate, and the other end of the connecting rod is fixedly connected to the mounting plate.

[0009] Furthermore, the assembly assembly includes a support rod, a fixed plate, an electric push rod, a lifting plate, and an assembly head. The support rod is fixedly installed on the top of the base, and the top end of the support rod is fixedly connected to the fixed plate. The electric push rod is fixedly installed on the top of the fixed plate, and the output end of the electric push rod is fixedly connected to the lifting plate. The assembly head is set at the bottom of the fixed plate by a threaded connection.

[0010] Furthermore, the rotary drive assembly includes a rotary cylinder assembly, a rotating plate, and a connecting column. The rotary cylinder assembly is fixedly installed on the top of the base, the output end of the rotary cylinder assembly is connected to the rotating plate, the connecting column is fixedly installed on the top of the rotating plate, and the top end of the connecting column is fixedly connected to the rotating ring.

[0011] Furthermore, the linkage assembly includes a first rotating block, a first plug-in shaft, a telescopic rod, a second rotating block, a second plug-in shaft, and a spring. One end of the first plug-in shaft is fixedly installed at the bottom of the first rotating block, and the other end of the first plug-in shaft is movably connected to the top of the rotating ring through a bearing.

[0012] Furthermore, one end of the telescopic rod is fixedly connected to the rotating block one, and the other end of the telescopic rod is limited to be inserted into the interior of the rotating block one. A limiting seat is fixedly installed at the end of the telescopic rod located inside the rotating block one. A spring is movably sleeved on the outside of the telescopic rod, and one end of the spring is engaged with the limiting seat. One end of the insertion shaft two is fixedly installed on the top of the rotating block two, and the other end of the insertion shaft two is limited to be inserted into the bottom end of the slider one and the slider two respectively.

[0013] The beneficial effects of this utility model are: With the clamping assembly in place, during use, the rotary drive assembly drives the rotating ring to rotate, causing the linkage assembly to rotate and drive slider one and slider two to slide inward and outward respectively. Slide grooves one and two on the mounting plate provide linear guidance for the sliders. Slide one and slider two respectively drive clamping blocks one and two to move together. Elastic pads one and two provide a soft and stable clamping force. When the bearing outer and inner rings are mounted on the mounting plate, clamping block one moves elastic pad one towards the center, thus moving the bearing outer ring. Simultaneously, clamping block two moves elastic pad two outward, thus clamping both the bearing outer and inner rings simultaneously. The entire assembly process... The combination of rotary drive and sliding mechanism ensures that the inner and outer rings of the bearing are concentrically and accurately aligned, preventing misalignment or damage, and providing stable clamping. By applying pressure synchronously through the clamping components, the outer and inner rings are subjected to uniform force simultaneously, ensuring uniform contact between the clamping blocks and the inner and outer rings of the bearing. This reduces uneven force distribution during assembly, thereby improving assembly accuracy. By incorporating synchronous clamping technology, the problem of insufficient fitting accuracy that may result from clamping only the outer or inner ring in traditional assembly methods is solved. With high-precision assembly, the bearing can maintain more stable performance and a longer service life during operation, reducing the risk of premature failure due to poor assembly.

[0021] Please see Figure 1-5As shown, a robot cross roller bearing assembly device includes: a base 1, and a support assembly and an assembly assembly are provided on the top of the base 1. A clamping assembly is provided on the inner side of the support component. The clamping assembly includes a rotary drive assembly, a rotating ring 16, a linkage assembly, a mounting plate 7, a first slider 25, a second slider 24, a first clamping block 17, an elastic pad 18, an elastic pad 19, and a second clamping block 20. The drive assembly is located on the top of the base 1, and the rotating ring 16 is located on the top of the drive assembly. The mounting plate 7 has two sliding grooves, a first groove 22 and a second groove 23, respectively, with the first groove 22 located outside the second groove 23. One end of the linkage assembly is movably connected to the rotating ring 16 for a limited position. Two sets of linkage assemblies are provided. One set of linkage components is movably connected at one end to slider 25, and the other set of linkage components is movably connected at one end to slider 24. Slider 25 is slidably installed inside slide groove 22, slide groove 23 is slidably installed inside slide groove 23, clamping block 17 is fixedly installed on the top of slider 25, elastic pad 18 is fixedly installed on the inner wall of clamping block 17, clamping block 20 is fixedly installed on the top of slider 24, elastic pad 29 is fixedly installed on the outer wall of clamping block 20, and clamping block 17 is located on the outside of clamping block 20.

[0022] Specifically, by providing a clamping assembly, during use, the rotary drive assembly drives the rotating ring 16 to rotate, causing the linkage assembly to rotate and drive slider 1 25 and slider 24 to slide inward and outward. Slide grooves 1 22 and 23 on the mounting plate 7 provide linear guidance for the sliders. Slide 1 25 and slider 24 respectively drive clamping blocks 1 17 and 2 20 to move together. Elastic pads 1 18 and 2 19 provide a soft and stable clamping force. When the outer and inner rings of the bearing are mounted on the mounting plate 7, clamping block 1 17 drives elastic pad 1 18 to move towards the center, thus moving the outer ring of the bearing. Simultaneously, clamping block 2 20 drives elastic pad 2 19 to move outward, thus simultaneously clamping both the outer and inner rings of the bearing. During the clamping operation, the combined principle of rotary drive and sliding mechanism ensures that the inner and outer rings of the bearing are concentrically and accurately aligned, preventing misalignment or damage and ensuring stable clamping. The clamping components apply pressure synchronously, ensuring that the outer and inner rings are evenly stressed simultaneously, guaranteeing uniform contact between the clamping blocks and the bearing's inner and outer rings. This reduces uneven force distribution during assembly, thereby improving assembly accuracy. The synchronous clamping technology solves the problem of insufficient fit that may result from clamping only the outer or inner ring in traditional assembly methods. High-precision assembly allows the bearing to maintain more stable performance and a longer service life during operation, reducing the risk of premature failure due to poor assembly. The elastic pad can be made of materials such as rubber.

[0023] In this embodiment, a support leg 2 is fixedly installed at the bottom of the base 1, and a foot pad 3 is fixedly installed at the bottom end of the support leg 2.

[0024] Specifically, the device is powered by an external power supply, and the device is connected to an external controller. The controller is electrically connected to the electric push rod 10 and the rotary cylinder assembly 13. The rotary cylinder assembly 13 can be used in sections and for positioning rotation as needed by being equipped with a pilot speed control valve. The controller can be a PLC board, which can be used after programming and debugging.

[0025] The support assembly includes a support column 4, a top plate 5, and a connecting rod 6. The support column 4 is fixedly installed on the top of the base 1, and the top end of the support column 4 is fixedly connected to the top plate 5. One end of the connecting rod 6 is fixedly connected to the top plate 5, and the other end of the connecting rod 6 is fixedly connected to the mounting plate 7.

[0026] Specifically, the support column 4 is fixedly installed on the top of the base 1, providing a stable foundation support for the entire structure and preventing the overall structure from tilting or moving. The top plate 5 is fixedly connected to the top of the support column 4, increasing the stability between the top plate 5 and the support column 4, and ensuring that the top plate 5 can evenly bear the pressure from above.

[0027] The assembly assembly includes a support rod 8, a fixed plate 9, an electric push rod 10, a lifting plate 11, and an assembly head 12. The support rod 8 is fixedly installed on the top of the base 1, and the top end of the support rod 8 is fixedly connected to the fixed plate 9. The electric push rod 10 is fixedly installed on the top of the fixed plate 9, and the output end of the electric push rod 10 is fixedly connected to the lifting plate 11. The assembly head 12 is set at the bottom of the fixed plate 9 by threaded insertion.

[0028] Specifically, in use, the switch of the electric push rod 10 is turned on, which causes the lifting plate 11 to move the assembly head 12, thereby enabling the assembly head 12 to assemble and use the cross roller bearing. Its working principle is the same as that of the assembly component in patent number CN202421321538.8.

[0029] The rotary drive assembly includes a rotary cylinder assembly 13, a rotating plate 14, and a connecting column 15. The rotary cylinder assembly 13 is fixedly installed on the top of the base 1. The output end of the rotary cylinder assembly 13 is connected to the rotating plate 14. The connecting column 15 is fixedly installed on the top of the rotating plate 14. The top end of the connecting column 15 is fixedly connected to the rotating ring 16.

[0030] Specifically, in use, the switch of the rotary cylinder assembly 13 is turned on, which causes the rotating plate 14 to drive the connecting column 15 to rotate, thereby allowing the rotating ring 16 to be rotated and adjusted. The rotary cylinder assembly 13 and the rotary actuator are integrated into a compact unit, which has a very simple structure, no exposed transmission parts, small space occupation, and high repeatability. The rotary cylinder assembly 13 should also include other necessary equipment, but since it is existing technology, it will not be described in detail here.

[0031] The linkage assembly includes a rotating block 26, a connecting shaft 27, a telescopic rod 28, a rotating block 29, a connecting shaft 20, and a spring 31. One end of the connecting shaft 27 is fixedly installed at the bottom of the rotating block 26, and the other end of the connecting shaft 27 is movably connected to the top of the rotating ring 16 via a bearing. One end of the telescopic rod 28 is fixedly connected to the rotating block 26, and the other end of the telescopic rod 28 is limited to be inserted into the interior of the rotating block 26. A limiting seat is fixedly installed at the end of the telescopic rod 28 located inside the rotating block 26. The spring 31 is movably sleeved on the outside of the telescopic rod 28, and one end of the spring 31 is engaged with the limiting seat. One end of the connecting shaft 20 is fixedly installed at the top of the rotating block 29, and the other end of the connecting shaft 20 is limited to be inserted into the bottom of the slider 25 and the slider 24, respectively.

[0032] Specifically, in use, the rotating ring 16, through the first insertion shaft 27, the first rotating block 26, the telescopic rod 28, the second rotating block 29, and the second insertion shaft 30, causes relative displacement between the rotating ring 16 and the first slider 25 and the second slider 24, respectively. At the same time, because the slider is restricted by the slide groove, the slider moves along the slide groove. In order to adapt to different types of cross roller bearings and different sizes of bearing inner and outer rings, when the first slider 25 or the second slider 24 moves to the appropriate position, the other set of sliders can continue to move under the action of the spring 31. This prevents the other set of sliders from being unable to move because the clamping block of one set of sliders is clamped and in contact with the inner or outer ring of the bearing, making the device more versatile and applicable to a wider range.

[0033] In summary, compared with existing technologies, this robot's cross-roller bearing assembly device has at least the following advantages: By incorporating a clamping assembly, during use, the rotary drive assembly drives the rotating ring 16 to rotate, causing the linkage assembly to rotate and drive slider 1 25 and slider 24 to slide inwards and outwards. The sliding grooves 1 22 and 23 on the mounting plate 7 provide linear guidance for the sliders. Slider 1 25 and slider 24 respectively drive clamping blocks 1 17 and 2 20 to move together. Elastic pads 1 18 and 2 19 provide a soft and stable clamping force. Thus, when the outer and inner rings of the bearing are mounted on the mounting plate 7, clamping block 1 17 drives elastic pad 1 18 to move towards the center, thereby moving the outer ring of the bearing. Simultaneously, clamping block 2 20 drives elastic pad 2 19 to move outwards. The rotating mechanism allows for simultaneous clamping of both the outer and inner rings of the bearing. Throughout the assembly process, the combination of rotary and sliding drive ensures that the inner and outer rings are concentrically and accurately aligned, preventing misalignment or damage and providing stable clamping. Synchronous pressure application through the clamping components ensures uniform force distribution on both the outer and inner rings, guaranteeing even contact between the clamping blocks and the bearing's inner and outer rings. This reduces uneven force distribution during assembly, thereby improving assembly accuracy. The synchronous clamping technology solves the problem of insufficient fit caused by clamping only the outer or inner ring in traditional assembly methods. High-precision assembly allows the bearing to maintain more stable performance and a longer service life during operation, reducing the risk of early failure due to poor assembly. The elastic pads can be made of materials such as rubber.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
