Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical automation and high-precision machining technology, specifically to a high-precision time-sharing clamping manipulator device. This device is particularly suitable for industrial supporting product processing scenarios in the field of metal materials and metal products manufacturing where extremely high processing precision is required, such as the manufacturing of aluminum alloy components in photovoltaic power generation equipment and the precision machining of aluminum alloy materials inside rail transit vehicles. Background Technology
[0002] With the continuous development of industrial technology, the manufacturing of metal materials and metal products is gradually moving towards higher precision and higher efficiency. Especially in the current market for industrial supporting products, such as the application of aluminum alloy materials in photovoltaic power generation equipment and the manufacturing of aluminum alloy components for rail transit vehicles, these fields place unprecedented demands on the processing precision of products. To meet these high-precision processing requirements, not only are advanced metal materials needed, but also high-precision processing equipment and processes must be employed to ensure that the dimensional accuracy, shape accuracy, and surface quality of the products meet design requirements.
[0003] In the high-precision machining of metal products, robotic arms are key equipment on automated production lines, and their clamping accuracy and stability directly affect the quality of the processed parts and production efficiency. However, traditional robotic arms often suffer from uneven clamping force distribution and inflexible clamping position adjustment during the clamping process, especially when handling workpieces requiring high-precision rotation control, such as the deflection mechanism of aircraft control surfaces in the aerospace field and the screw in precision rotating mechanisms. These problems are particularly prominent.
[0004] In current technologies, circular screws are often used as drive and support structures to achieve high-precision rotation control. However, circular screws cannot operate in mid-air, and the precision rotating mechanism base below them is restricted by the clamping mechanism during movement. When the clamping mechanism clamps the screw, the base cannot avoid the clamping manipulator, causing the base to frequently stop during movement to wait for clamping or releasing operations. This not only reduces production efficiency but also increases equipment wear and energy consumption. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Example
[0027] like Figure 1-5 As shown, a high-precision time-sharing clamping manipulator includes a bracket 1. A hydraulic cylinder 2 is fixedly connected to the middle of the inner side of the bracket 1. A stopper rod 3 is fixedly connected to the output end of the hydraulic cylinder 2. A first support plate 4 is fixedly connected to one end of the stopper rod 3. Fixed rods 5 are fixedly connected to the four corners of the outer surface of the first support plate 4. A second support plate 6 is fixedly connected to the end of the fixed rod 5 away from the first support plate 4. A guide rod 7 is fixedly connected to the middle of the inner side of the first support plate 4 and the second support plate 6. A slide seat 8 is slidably connected to the outer surface of the guide rod 7. Connecting rods 9 are fixedly connected to both sides of the outer surface of the slide seat 8. The connecting rods 9 are slidably connected to the first support plate 4 and fixedly connected to the bracket 1. Support arms 10 are rotatably connected to both sides of the inner side of the slide seat 8. A clamping arm 11 is rotatably connected to the end of the support arm 10 away from the slide seat 8. A support rod 12 is fixedly connected to the middle of the outer surface of the clamping arm 11. The support rod 12 is rotatably connected to the second support plate 6.
[0028] In practical use, through the arrangement of the plunger 3, guide rod 7, slide 8, connecting rod 9, support arm 10, and clamping arm 11, the output end of the hydraulic cylinder 2 is connected to the first support plate 4 via the plunger 3. The first support plate 4 is connected to the second support plate 6 via four sets of fixing rods 5. The guide rod 7 is fixed to the middle of the inner surface of the first support plate 4 and the second support plate 6, and the slide 8 is slidably connected to its surface. One end of the connecting rod 9 is fixed to the slide 8, and the other end is fixed to the bracket 1. The middle of the outer surface of the clamping arm 11 is connected to the second support plate 6 via the support rod 12 to support the clamping arm 11. One end of the support arm 10 is connected to the clamping arm 11, and the other end is connected to the slide 8. When the plunger 3 extends and retracts under the action of the hydraulic cylinder 2, it can drive the first support plate 4 and the second support plate 6 to move. The connecting rod 9 keeps the position of the slide 8 stationary, while the movement of the first support plate 4 and the second support plate 6 drives the guide rod 7 to move, so that the slide 8 is driven by the support arm 10. The clamping arm 11 rotates at a certain angle around the support rod 12 to clamp or release the screw 15. This allows the device to adjust the position of the clamping arm 11 while simultaneously adjusting the angle of the two sets of clamping arms 11. Six robotic arms are evenly distributed around the screw 15, providing stable clamping force and preventing vibration or displacement of the precision rotating mechanism base of the composite rolling element due to unstable clamping during movement, thus ensuring the accuracy of movement. When the base needs to pass through the position of a robotic arm, the clamping arm 11 is immediately retracted and released to allow the base to pass. After the base passes, it is immediately clamped and reset. The six robotic arms extend and retract in turn to ensure that the base can pass smoothly at any time, ensuring the smooth operation of the base. Since the robotic arms can clamp and release in stages, the base does not need to stop frequently to wait for clamping or releasing during movement, thus achieving continuous movement, saving a lot of time, and improving work efficiency and convenience.
[0029] In this embodiment, a rubber pad 13 is fixedly connected to one side of the inner side of the clamping arm 11, and an anti-slip groove 14 is provided on the inner side of the rubber pad 13. A screw 15 is movably connected to the inner side of the rubber pad 13.
[0030] In practical use, the rubber pad 13 and anti-slip groove 14 are designed to prevent scratches or damage to the surface of the screw 15 due to the soft material of the rubber pad 13. This avoids damage to the surface of the screw 15 caused by friction during the gripping process. At the same time, the rubber pad 13 can better fit the surface of the screw 15. Even if the screw 15 has an irregular shape, the rubber pad 13 can deform and fit tightly to the surface of the screw 15, thereby providing a uniform gripping force. The anti-slip groove 14 increases the friction between the rubber pad 13 and the screw 15, effectively preventing the screw 15 from slipping and ensuring the stability of the gripping.
[0031] In this embodiment, sleeves 16 are fixedly connected to both sides of the inner side of the bracket 1, and slide rods 17 are slidably connected inside the sleeves 16. The slide rods 17 are fixedly connected to the first support plate 4.
[0032] In practical use, with the sleeve 16 and slide rod 17, when the first support plate 4 moves under the action of the hydraulic cylinder 2 and the stopper rod 3, the slide rod 17 extends and retracts inside the sleeve 16, ensuring that the stopper rod 3 moves in a straight line inside the hydraulic cylinder 2, avoiding deviation or shaking during the movement, and reducing assembly errors caused by unstable movement.
[0033] In this embodiment, a turntable 18 is fixedly connected to the lower surface of the bracket 1, and a support column 19 is rotatably connected to the lower surface of the turntable 18.
[0034] In practical use, the turntable 18 is set up and the support column 19 provides rotational support for the turntable 18, so that the turntable 18 and the clamping arm 11 can be adjusted according to actual needs. This allows for precise alignment with the clamping position of the screw 15, ensuring even distribution of clamping force and preventing the screw 15 from shaking due to improper clamping angle.
[0035] In this embodiment, a slider 20 is fixedly connected to the lower surface of the support column 19, and a slide rail 21 is slidably connected to the bottom inside the slider 20.
[0036] In practical use, by setting the slider 20, the position of the slider 20 on the outer surface of the slide rail 21 can be changed, which makes it easier to adjust the position of the robot and make it more convenient to debug during installation.
[0037] In this embodiment, a limiting plate 22 is fixedly connected to the outer surface of the slider 20, and a first mounting hole 23 is provided on the upper surface of the limiting plate 22.
[0038] In practical use, by setting the limiting plate 22, after the position of the slider 20 is adjusted, the limiting plate 22 cooperates with the external bolt through the first mounting hole 23 to fix the slider 20 and prevent displacement during use.
[0039] In this embodiment, a support leg 24 is fixedly connected to the outer surface of the turntable 18, and a second mounting hole 25 is provided on both sides of the outer surface of the support leg 24.
[0040] In practical use, the support legs 24 are used to fix the turntable 18 after the angle of the turntable 18 is adjusted. The support legs 24 are used in conjunction with the external bolts through the second mounting holes 25 to provide stable support for the turntable 18. At the same time, the four sets of support legs 24 can evenly distribute the load of the turntable 18 to other support structures, avoiding damage or deformation of the equipment due to excessive local stress.
[0041] In this embodiment, a base plate 26 is fixedly connected to the lower surface of the slide rail 21, and a support member 27 is fixedly connected to the lower surface of the base plate 26.
[0042] In practical use, the base plate 26 supports and fixes the slide rail 21 and the support leg 24 through the setting of the base plate 26 and the support member 27, connecting them into a whole for easy installation, and the support member 27 supports the base plate 26.
[0043] Working principle: In use, the base plate 26 is fixed to the support 27, and the support column 19 provides rotational support for the turntable 18. This allows the turntable 18 and the clamping arm 11 to adjust their angles according to actual needs, precisely aligning with the clamping position of the screw 15. This changes the position of the slider 20 on the outer surface of the slide rail 21, adjusting the position of the robotic arm. The limiting plate 22, through the first mounting hole 23, engages with external bolts to fix the slider 20. The support leg 24, through the second mounting hole 25, engages with external bolts to fix the turntable 18. Six robotic arms are evenly distributed around the screw 15, providing stability. The clamping force is such that when the machine base needs to pass through the position of a certain robot arm, the stop rod 3 retracts under the action of the hydraulic cylinder 2, driving the first support plate 4 and the second support plate 6 to move towards the hydraulic cylinder 2. The connecting rod 9 keeps the position of the slide 8 stationary, while the movement of the first support plate 4 and the second support plate 6 drives the guide rod 7 to move, so that the slide 8 drives the clamping arm 11 to rotate around the support rod 12 at a certain angle through the support arm 10, releasing the screw 15 and allowing the machine base to pass through. After the machine base passes through, it immediately clamps and resets. The six robot arms extend and retract in turn to ensure that the machine base can pass smoothly at any time, ensuring the smooth operation of the machine base.
[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
