[0014] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.

[0015] In the description of this utility model, it should be understood that the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 The directions or positional relationships shown are for the purpose of describing this utility model only, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0016] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0017] To solve the above technical problems, such as Figure 1-2 As shown, this utility model designs an automatic bushing feeding device, including a conveyor line 1, a robot arm 2, a motor 3, and a clamping mechanism. The conveyor line 1 is used to transport bushings laterally to ensure that the bushings can accurately reach the designated position. The conveyor line 1 is preferably a belt conveyor line, which provides smooth transmission. The robot arm 2 is set on one side of the conveyor line 1. The robot arm 2 can be an ABB multi-joint type robot arm, which has high flexibility and is suitable for use in situations with limited space or complex workpiece shapes. The end of the robot arm is equipped with a motor 3, and the output shaft of the motor 3 is connected to a turntable 4 for flexible rotation.

[0018] The clamping mechanism is cleverly positioned below the turntable 4 and consists of key components such as a base plate 5, a support plate 6, a linear cylinder 7, a push plate 8, a connecting rod 9, and a clamping block 10. The base plate 5 is fixedly connected to the turntable 4, providing a stable support foundation for the entire clamping mechanism. The cylinder body of the linear cylinder 7 is firmly mounted on the base plate 5, and its piston rod is parallel to the axis of the turntable 4 and fixedly connected to the push plate 8. Through the extension and retraction of the linear cylinder 7, the push plate 8 is pushed to reciprocate along a straight line. The support plate 6 is vertically fixedly connected to the base plate 5, forming a stable support structure. Symmetrically arranged on the left and right sides of the push plate 8 are levers 11 that tilt towards one side of the base plate 5. One end of the lever 11 is connected to the connecting rod 9, which is connected to the support plate 6 via the support plate 6. The support shaft is connected to the support plate 6. When the push plate 8 moves back and forth along a straight line under the drive of the linear cylinder 7, the lever 11 can accurately move the connecting rod 9 to rotate around the support shaft, thereby driving the clamping block 10 at the other end of the connecting rod 9 to perform clamping and releasing actions. This unique structural design not only achieves precise clamping of the bushing, but also ensures the stability and reliability of the clamping process, effectively preventing the bushing from falling or being damaged during the feeding process. Through this innovative structural design, the automatic bushing feeding device of this utility model can significantly improve production efficiency, reduce labor costs, and at the same time ensure the stability and accuracy of the feeding process, providing strong technical support for the automated production of bushings.

[0019] In this embodiment, it is further preferred that the support plate 6 has an arc-shaped groove on the side away from the bottom plate 5. The design of the arc-shaped groove allows the clamping block 10 to fit more closely to the outer surface of the bushing when clamping it.

[0020] In this embodiment, it is further preferred that the clamping blocks 10 are all arc-shaped blocks, and the two clamping blocks 10 are symmetrically arranged on the left and right. The inner diameter of the clamping block 10 is adapted to the outer diameter of the bushing, which can ensure that the clamping block 10 can closely fit the outer surface of the bushing when clamping the bushing, so as to achieve precise clamping and avoid unstable clamping or damage to the bushing due to the gap between the clamping block 10 and the bushing. In addition, the design of the arc-shaped clamping block 10 can better disperse the clamping force, so that the clamping force is evenly distributed on the outer surface of the bushing, thereby reducing the damage to the bushing caused by excessive local pressure, protecting the surface quality of the bushing, and improving the product qualification rate.

[0021] In this embodiment, it is further preferred that the end of the connecting rod 9 is provided with a U-shaped seat 12, the outer side of the clamping block 10 is provided with a limiting seat 13, the outer side of the limiting seat 13 is provided with a bushing, and a connecting shaft is inserted into the bushing. The connecting shaft cooperates with the insertion hole of the U-shaped seat 12 of the connecting rod 9. Through the cooperation between the U-shaped seat 12 and the connecting shaft, the position of the clamping block 10 can be accurately positioned, ensuring the accuracy and consistency of the clamping action. This structural design makes the connection between the clamping block 10 and the connecting rod 9 more flexible, and facilitates disassembly and replacement. When it is necessary to maintain or replace the clamping block 10 or the connecting rod 9, the operation can be completed quickly by simply disassembling the connecting shaft, which greatly reduces maintenance costs and time.

[0022] In this embodiment, it is further preferred that bolt mounting holes are provided at the four corners of the base plate 5. The base plate 5 is detachably connected to the turntable 4 by bolt connection. The bolt connection makes the installation and disassembly between the base plate 5 and the turntable 4 very convenient. This detachable connection allows users to quickly replace or adjust the clamping mechanism according to different production or maintenance needs, which greatly improves the adaptability and flexibility of the equipment.

[0023] Considering that the bushing cannot accurately reach the loading position when moving on conveyor line 1 without being limited, in order to solve this problem, such as Figure 3 As shown, based on the above embodiment, further modifications are made, with baffles 15 symmetrically provided on both sides of the conveyor line 1. By setting baffles 15 on both sides of the conveyor line 1, the lateral movement of the bushing during the conveying process can be effectively restricted, ensuring that the bushing can accurately reach the feeding position along the predetermined track, thereby improving the accuracy and efficiency of feeding.

[0024] The baffle 15 is mounted on the side frame 14 of the conveyor line 1 via an adjustable positioning assembly. The adjustable positioning assembly includes an adjusting plate 16, a vertical rod 17, and a connecting rod 18. The side frame 14 of the conveyor line 1 has a waist-shaped hole 19. The adjusting plate 16 has a positioning hole, in which a screw is inserted. The screw passes through the waist-shaped hole 19 and engages with a nut to fix the position of the adjusting plate 16. The vertical rod 17 is mounted on the adjusting plate 16. One end of the connecting rod 18 is fixedly connected to the top of the vertical rod 17. The connecting rod 18 is perpendicular to the vertical rod 17, and the other end is fixedly connected to the baffle 15. The design of the adjustable positioning assembly allows the position of the baffle 15 to be flexibly adjusted according to different specifications of bushings. By loosening the screw, its position in the waist-shaped hole 19 can be adjusted, thereby quickly changing the spacing of the baffle 15 to accommodate bushings of different diameters, greatly improving the versatility and adaptability of the conveyor line 1.

[0025] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made by those skilled in the art based on the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
