Description

Technical Field

[0001] This utility model belongs to the field of thrust rod processing technology, specifically relating to a robotic arm for thrust rod processing. Background Technology

[0002] A thrust bar, also known as an anti-roll bar, is an important automotive component that plays an auxiliary role in the suspension system. Its function is to prevent excessive lateral tilting of the vehicle body when cornering, which could cause the vehicle to roll over and lead to an accident, and to improve the vehicle's balance.

[0003] For example, publication number CN 116079481 B proposes a robotic arm for processing push rods. The left robotic arm structure and gripper provide basic gripping and transfer of the push rod, while the right robotic arm structure, in conjunction with a cooperating robotic arm, provides adaptive support for the push rod (straight or V-shaped) gripped by the gripper and assists in drilling the end of the push rod. This eliminates the need for other tooling and manual clamping, solving the problems of existing robotic arms having limited functionality, requiring different clamping methods for drilling push rods, and involving cumbersome processing steps. Drilling is performed directly under the gripper's control, followed by transfer, reducing processing steps and improving drilling and transfer efficiency. Furthermore, the cooperating robotic arm mounted on the right robotic arm structure has strong adaptability; depending on the push rod specifications, the right robotic arm structure can adaptively adjust the position of the cooperating robotic arm to meet the drilling needs of various types and specifications of push rods.

[0004] While the above-mentioned cases can improve efficiency in actual use, the variety of push rods and the inability of the gripper to grasp push rods of different models limit the device. Therefore, this utility model provides a robotic arm for push rod processing. Utility Model Content

[0005] The purpose of this invention is to provide a robotic arm for processing push rods, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a manipulator for processing push rods, including a mounting base, a lifting platform at the top of the mounting base, a telescopic arm at one end of the lifting platform, a rotating plate on the front of the telescopic arm, two symmetrically arranged limiting members slidably connected to the front of the rotating plate, and a set of rotating members inside the opposing surfaces of the two limiting members.

[0007] In a preferred embodiment, the lifting end of the lifting platform is provided with a first rotating arm, and the end of the first rotating arm is provided with a second rotating arm, one end of the second rotating arm being fixedly connected to the fixed end of the telescopic arm.

[0008] In a preferred embodiment, an adjustment plate is fixedly connected to the telescopic end of the telescopic arm. The front of the adjustment plate is rotatably connected to the back of the rotating plate. A rotary motor is fixedly connected to the back of the adjustment plate, and the output shaft of the rotary motor is fixedly connected to the rotating plate.

[0009] In a preferred embodiment, a connecting frame is fixedly connected to the front of the rotating plate, and two limiting members are symmetrically slidably connected inside the connecting frame. The limiting members have grooves on both sides that are adapted to the connecting frame.

[0010] In a preferred embodiment, a drive motor is fixedly connected to one side of the connecting frame, and a double-threaded screw is fixedly connected to the output shaft of the drive motor. The two limiting members include sliding blocks that are symmetrically threaded to the outside of the double-threaded screw.

[0011] In a preferred embodiment, a connecting plate is fixedly connected to the front of each sliding block, and a fixing member is fixedly connected to the opposite surface of each of the two connecting plates. The two sets of rotating members are respectively arranged on the opposite surface of the two fixing members.

[0012] In a preferred embodiment, each set of rotating components includes a semi-circular first rotating component rotatably connected to the fixed component, two semi-circular second rotating components rotatably connected to the side of each semi-circular first rotating component facing the other semi-circular first rotating component, two symmetrically arranged semi-circular third rotating components rotatably connected to the front side of the second rotating component, and two semi-circular fourth rotating components rotatably connected to the front side of the third rotating component.

[0013] In a preferred embodiment, the diameter of each of the rotating components is slightly smaller than the radius of the component that encloses it, and each of the fourth rotating components has two limiting protrusions on its front side, with a deformation cavity inside each limiting protrusion.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This robotic arm for processing push rods, by setting up slidable limiting parts and multiple rotating parts (including the first to fourth rotating parts), can flexibly adjust the clamping space to adapt to push rods of different diameters and shapes. The diameter of each rotating part is designed to be slightly smaller than the rotating part surrounding it. Together with the limiting protrusions and deformation cavities, it achieves a stable clamping of the end of the push rod, solving the problem that traditional grippers cannot grasp push rods of different models.

[0016] The robotic arm for processing the push rod features a rotary motor-driven rotating plate design, which allows the push rod to automatically adjust its angle during processing. Combined with multi-level limiting of fixed and rotating components, it ensures stability and accuracy during processing and reduces errors caused by human operation. Attached Figure Description

[0021] The present invention will be further described below with reference to the embodiments.

[0022] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0023] Please see Figure 1-3This utility model provides a manipulator for processing push rods, including a mounting base 1, a lifting platform 2 on the top of the mounting base 1, a telescopic arm 5 at one end of the lifting platform 2, a rotating plate 8 on the front of the telescopic arm 5, two symmetrically arranged limiting members 9 slidably connected to the front of the rotating plate 8, a first rotating arm 3 at the lifting end of the lifting platform 2, a second rotating arm 4 at the end of the first rotating arm 3, one end of the second rotating arm 4 being fixedly connected to the fixed end of the telescopic arm 5, an adjusting plate being fixedly connected to the telescopic end of the telescopic arm 5, the front of the adjusting plate being rotatably connected to the back of the rotating plate 8, and a rotary motor 6 being fixedly connected to the back of the adjusting plate, the output shaft of the rotary motor 6 being fixedly connected to the rotating plate 8. The entire manipulator is based on the mounting base 1, and the lifting platform 2 provides vertical movement capability. When it is necessary to grasp or process push rods of different heights, the lifting platform 2 adjusts the height of the first rotating arm 3 through its lifting end. The second rotating arm 4 is located at the end of the first rotating arm 3, and one end of the second rotating arm 4 is fixedly connected to the fixed end of the telescopic arm 5. By cooperating with the first rotating arm 3 and the second rotating arm 4, the angle and position of the telescopic arm 5 in the vertical plane can be further adjusted, expanding the operating range of the robot. The front of the telescopic arm 5 is provided with a rotating plate 8, and an adjustment plate is fixedly connected to the telescopic end of the telescopic arm 5. The telescopic arm 5 moves the rotating plate 8 to the vicinity of the push rod through the telescopic movement. A rotary motor 6 is fixedly connected to the back of the adjustment plate, and the output shaft of the rotary motor 6 is fixedly connected to the rotating plate 8. When it is necessary to adjust the processing angle of the push rod, the rotary motor 6 drives the rotating plate 8 to rotate around the rotation connection of the adjustment plate, thereby driving the push rod after gripping to rotate to the required angle.

[0024] It should be noted in the above case that the lifting platform 2, the first rotating arm 3 and the second rotating arm 4 are all existing technologies and therefore have not been described in detail.

[0025] In this embodiment, a set of rotating members is provided inside the opposing surfaces of the two limiting members 9. A connecting frame 7 is fixedly connected to the front of the rotating plate 8. The two limiting members 9 are symmetrically slidably connected inside the connecting frame 7. Slide grooves 902 adapted to the connecting frame 7 are provided on both sides of the limiting members 9. A drive motor 10 is fixedly connected to one side of the connecting frame 7. A double-threaded screw 11 is fixedly connected to the output shaft of the drive motor 10. The two limiting members 9 include sliding blocks 901 symmetrically threaded to the outside of the double-threaded screw 11. A connecting plate 903 is fixedly connected to the front of each sliding block 901. Fixing members 904 are fixedly connected to the opposing surfaces of the two connecting plates 903. The two sets of rotating members are respectively arranged on the opposing surfaces of the two fixing members 904. Each set of rotating components includes a semi-circular first rotating component 9041 rotatably connected to the fixed component 904. Two semi-circular second rotating components 9042 are rotatably connected to the side of each semi-circular first rotating component 9041 facing the other semi-circular first rotating component 9041. Two symmetrically arranged semi-circular third rotating components 9043 are rotatably connected to the front side of the second rotating component 9042. Two semi-circular fourth rotating components 9044 are rotatably connected to the front side of the third rotating component 9043. The diameter of each rotating component is slightly smaller than the radius of the rotating component surrounding it. Two limiting protrusions 90441 are provided on the front side of each fourth rotating component 9044. A deformation cavity 90442 is opened inside each limiting protrusion 90441.

[0026] When the push rod is not gripped, the two limiting members 9 are in their maximum open state inside the connecting frame 7. At this time, the two sliding blocks 901 on the double-threaded screw 11 are located at both ends of the double-threaded screw 11. When the push rod needs to be gripped, the drive motor 10 starts and drives the double-threaded screw 11 to rotate. Since the threads of the double-threaded screw 11 are opposite, the two sliding blocks 901 will slide towards each other along the sliding groove 902 in the connecting frame 7, causing the limiting members 9 to close in the middle. During the closing process of the limiting members 9, the first rotating member 9041 on the fixing member 904 first contacts the surface of the push rod. Since the first rotating member 9041 is semi-circular and rotatably connected to the fixing member 904, it will automatically adjust the angle according to the shape of the push rod. As the limiting members 9 further close, the second rotating member 9042, the third rotating member 9043 and the fourth rotating member 9044 will contact the push rod step by step. Each rotating component is connected by rotation, which allows for further fine-tuning of the angle and forms multi-point, multi-faceted contact with the thrust rod. When the fourth rotating component 9044 contacts the thrust rod, the limiting protrusion 90441 on its front side will be embedded into the groove or irregular surface at the end of the thrust rod. The design of the deformation cavity 90442 makes the limiting protrusion 90441 have a certain elasticity, which can further adapt to the shape of the thrust rod and enhance the fixing effect.

[0027] The multi-stage rotating component design allows the robot to flexibly adapt to thrust rods of different diameters and shapes (straight rods, V-shaped rods, etc.), solving the problem that traditional grippers can only grasp thrust rods of a single specification. The multi-point, multi-faceted contact of the rotating component and the fixing effect of the limiting protrusion 90441 enhance the robot's gripping stability of the thrust rod, reduce vibration and displacement during processing, and improve the accuracy of operations such as drilling. The semi-circular design of the rotating component and the elastic contact of the limiting protrusion 90441 avoid indentations or damage to the surface of the thrust rod caused by traditional clamping methods, thus improving product quality.

[0028] The working principle and usage process of this utility model are as follows: First, when it is necessary to grasp or process push rods of different heights, the lifting platform 2 adjusts the height of the first rotating arm 3 through its lifting end. The end of the first rotating arm 3 is provided with a second rotating arm 4, one end of which is fixedly connected to the fixed end of the telescopic arm 5. Through the cooperation of the first rotating arm 3 and the second rotating arm 4, the angle and position of the telescopic arm 5 in the vertical plane can be further adjusted, expanding the operating range of the robot. The front of the telescopic arm 5 is provided with a rotating plate 8, and the telescopic end of the telescopic arm 5 is fixedly connected with an adjustment plate. The telescopic arm 5 moves the rotating plate 8 to the vicinity of the push rod through telescopic movement. The back of the adjustment plate is fixedly connected with a rotary motor 6, and the output shaft of the rotary motor 6 is fixedly connected to the rotating plate 8. When it is necessary to adjust the processing angle of the push rod, the rotary motor 6 drives the rotating plate 8 to rotate around the rotating connection of the adjustment plate, thereby driving the grasped push rod to rotate to the required angle. When the push rod is not grasped, the two limiting pieces 9 are in the maximum open state inside the connecting frame 7. At this time, the double-threaded screw 1 The two sliding blocks 901 on 1 are located at both ends of the double-threaded screw 11. When it is necessary to grab the push rod, the drive motor 10 starts and drives the double-threaded screw 11 to rotate. Since the threads of the double-threaded screw 11 are opposite, the two sliding blocks 901 will slide towards each other along the sliding groove 902 in the connecting frame 7, causing the limiting member 9 to close in the middle. During the closing process of the limiting member 9, the first rotating member 9041 on the fixing member 904 first contacts the surface of the push rod. Since the first rotating member 9041 is semi-circular and rotatably connected to the fixing member 904, it will automatically adjust the angle according to the shape of the push rod. As the limiting member 9 closes further, the second rotating member 9042, the third rotating member 9043 and the fourth rotating member 9044 will contact the push rod step by step. Each rotating component is connected by rotation, which allows for further fine-tuning of the angle and forms multi-point, multi-faceted contact with the thrust rod. When the fourth rotating component 9044 contacts the thrust rod, the limiting protrusion 90441 on its front side will be embedded into the groove or irregular surface at the end of the thrust rod. The design of the deformation cavity 90442 makes the limiting protrusion 90441 have a certain elasticity, which can further adapt to the shape of the thrust rod and enhance the fixing effect.
