Technical Field

[0001] This invention belongs to the field of workpiece assembly, and particularly relates to a steel foot loading and assembly device. Background Technology

[0002] Insulating bushings are devices installed between conductors at different potentials or between a conductor and a ground potential component. They are capable of withstanding voltage and mechanical stress. In the assembly process of suspension porcelain insulator bushings, adhesives are used to assemble the iron cap, steel foot, and porcelain component into a single unit to form the final product. Current assembly methods involve manually installing the three-insulating bushings and steel feet together. Due to the large number of bushings to be installed, the workers' installation speed is slow, and manual assembly is susceptible to errors due to the operator's skill level.

[0003] For example, a Chinese patent discloses a porcelain insulator positioning and assembly device [application number: CN202222105382.7], which includes a horizontal seat, a vertical plate fixed to the side wall of the horizontal seat, two fixed plates fixed to the upper end of the horizontal seat, and a lead screw rotatably connected to the side wall of each of the two fixed plates via bearings. The ends of the two lead screws are fixed to each other. A motor is fixed to the side wall of one fixed plate. The main shaft of the motor passes through the fixed plate and is fixed to the end of one lead screw. A slider is threadedly rotatably connected to the circumferential side wall of each lead screw. A limit frame is fixed to the side wall of each slider. An insulator body is connected to the inside of each limit frame via a limit clamping device. Two sets of symmetrically arranged abutting devices are provided on the side wall of the vertical plate. The slider abuts against the side wall of the vertical plate. The bottom of the limit frame abuts against the upper end of the horizontal seat. A through groove is opened through the upper end of the horizontal seat. Multiple insulator bodies abut against the inner wall of the through groove. Summary of the Invention

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0017] This embodiment provides a steel foot loading and assembly device, combined with Figure 1-6As shown, the device includes a frame 10, an assembly platform on which a sleeve clamping and fixing structure 11 is provided. A feeding and transporting support rod 12 is provided on the top of the frame 10. A feeding frame 13 is slidably mounted on the feeding and transporting support rod 12. A steel foot is hung on the feeding frame 13. A steel foot gripping structure 14 is provided on the frame 10 between the feeding and transporting support rod 12 and the sleeve clamping and fixing structure 11. The steel foot gripping structure 14 can move up and down in the vertical direction.

[0018] In this embodiment, the steel foot, after passing visual inspection, is placed on the feeding frame 13. The feeding frame 13 is connected to the conveyor chain set on the feeding transport support rod 12. The feeding frame 13 moves along the feeding transport support rod 12 towards the steel foot gripping structure 14. Then, the steel foot on the feeding frame 13 is gripped by the lifting and lowering of the steel foot gripping structure 14. The sleeve clamping and fixing structure 11 has a sleeve transport mechanism on its side. The sleeve transport mechanism first places the sleeve on the sleeve clamping and fixing structure 11 and fixes it therein. The steel foot gripping structure 14 then lifts and lowers the steel foot to align with the sleeve and inserts it into the sleeve to complete the installation. The installation of the sleeve and the steel foot, as well as the transport of the steel foot, are all carried out automatically by machinery, eliminating the need for manual installation, thus improving both efficiency and installation qualification.

[0019] The steel foot gripping structure 14 includes a steel foot lifting plate 15. The steel foot lifting plate 15 is connected to a linear drive mounted on the frame 10 and is slidably connected to the frame 10 via a steel foot lifting shaft 16. A steel foot forward and backward lateral movement shaft 17 is provided on the steel foot lifting plate 15. A steel foot gripping plate 18 is slidably mounted on the steel foot forward and backward lateral movement shaft 17. The steel foot gripping plate 18 is connected to a linear drive mounted on the steel foot lifting plate 15 and can move closer to or further away from the feed frame 13 along the horizontal forward and backward direction. A gripper assembly is provided on the steel foot gripping plate 18.

[0020] In this embodiment, after the feeding frame 13 approaches the steel foot gripping structure 14, there is still a certain distance between the feeding frame 13 and the steel foot gripping structure 14. By sliding the steel foot gripping plate 18 on the steel foot forward and backward transverse axis 17, the gripper assembly can approach the feeding frame 13, thereby enabling the gripper assembly to grip the steel foot.

[0021] The steel foot gripping plate 18 is also provided with a steel foot left and right transverse axis 19. The gripper assembly includes a gripper block 20 slidably disposed on the steel foot left and right transverse axis 19. The steel foot gripping plate 18 is provided with a linear actuator to push the gripper block 20 to move laterally. The gripper assembly also includes a pair of single-arm claws 21 rotatably disposed on the gripper block 20. The feeding frame 13 is provided with a plurality of slots 22. The slot 22 has at least two insertion sections, and the width of the end insertion section is smaller than the width of the front insertion section.

[0022] In this embodiment, the gripper assembly achieves lifting and three-axis movement (lifting, forward and backward, left and right) via the steel foot lifting shaft 16, the steel foot forward and backward lateral movement shaft 17, and the steel foot left and right lateral movement shaft 19. This provides a large range of movement for the gripper assembly to grasp and install the steel foot onto the sleeve, ensuring the accuracy of grasping and installing the steel foot. It also prevents impact wear caused by the steel foot not being aligned with the sleeve during placement and installation. Furthermore, the width of the end insertion section on the slot 22 is smaller than the width of the front insertion section, so the steel foot will not rub against the slot 22 during the process of the gripper assembly grasping the steel foot and removing it by lateral movement.

[0023] The sleeve clamping and fixing structure 11 includes an assembly placement plate 23, on which a clamping station is provided. Several clamping blocks 24 are provided around the clamping station. Each clamping block 24 corresponds to a linear guide rail 25 provided on the assembly placement plate 23. The clamping block 24 is slidably disposed on the corresponding linear guide rail 25 so as to move closer to or away from the clamping station along a straight line. The several clamping blocks 24 are connected to a synchronous movement drive structure and move synchronously through the synchronous movement drive structure.

[0024] In this embodiment, during the process of fixing the sleeve, the sleeve is placed on the clamping station, and several clamping blocks 24 move synchronously through the synchronous movement drive structure and move towards the sleeve, so that the several clamping blocks 24 abut against the outer surface of the sleeve and thus fix the sleeve. The movement trajectory of the clamping blocks 24 is restricted by the linear guide rail 25 to ensure that the several clamping blocks 24 abut against the sleeve synchronously, preventing the sleeve from tipping over due to sequential movement.

[0025] The synchronous movement drive includes a drive disk 26 that is rotatable and located below the assembly placement plate 23. The bottom of the clamping block 24 is provided with a drive shaft 27. The drive shaft 27 slides on a limiting groove 28 located on the assembly placement plate 23. The limiting groove 28 is parallel to the corresponding linear guide rail 25. The drive shaft 27 passes downward through the limiting groove 28. The drive disk 26 has several arc-shaped guide grooves 29, the same number as the drive shaft 27. The drive shaft 27 extends into the corresponding arc-shaped guide groove 29 and slides in connection with it.

[0026] In this embodiment, the drive disk 26 rotates back and forth repeatedly by a rotation power source. The rotation angle is limited by both ends of the arc-shaped guide groove 29. When the pick-up shaft 27 is in contact with one end of the arc-shaped guide groove 29 or has not yet come into contact with it, the drive disk 26 changes direction and rotates. The arc-shaped guide groove 29 pushes the pick-up shaft 27 to move. The limiting groove 28 restricts the pick-up shaft 27 to move only in a direction parallel to the linear guide rail 25, thereby further ensuring that the clamping block 24 can only move in a straight line.

[0027] The outer surface of the drive shaft 27 is rotatably provided with a connecting sleeve shaft 35 located in the arc-shaped guide groove 29.

[0028] In this embodiment, the friction between the drive shaft 27 and the arc-shaped guide groove 29 is reduced by connecting the sleeve shaft 35.

[0029] The drive disk 26 is rotatably mounted on the assembly plate 23. The drive disk 26 is fixedly mounted with a swing arm 30. The end of the swing arm 30 away from the drive disk 26 is rotatably connected to the output shaft of the telescopic cylinder 31. The other end of the telescopic cylinder 31 is rotatably mounted on the frame 10 or the assembly plate 23.

[0030] In this embodiment, the drive disk 26 rotates repeatedly by the back-and-forth movement of the output shaft of the telescopic cylinder 31. The positional movement of the telescopic cylinder 31 caused by the rotation of the drive disk 26 is solved by the rotational connection between the telescopic cylinder 31 and the frame 10 or the mounting plate 23, and the rotational connection between the swing arm 30 and the output shaft of the telescopic cylinder 31.

[0031] The clamping block 24 is provided with a roller support plate 32 extending toward the clamping station, and a roller 33 is rotatably provided on the end of the roller support plate 32 near the clamping station.

[0032] In this embodiment, the roller 33 can reduce the friction between the roller and the sleeve. In addition, the outer surface of the roller 33 can be covered with a rubber ring, which can increase the stability when fixing the sleeve. Furthermore, after the sleeve and steel foot are installed, they need to be pulled out. The roller 33 further facilitates the smooth pulling out process and reduces wear.

[0033] The clamping station is provided with a sleeve placement ring 34, and the sleeve placement ring 34 is provided with a sleeve placement groove. The roller support plate 32 located above the sleeve placement ring 34 and there is a gap between it and the sleeve placement ring 34.

[0034] In this embodiment, when placing the sleeve, the sleeve is inserted into the sleeve placement groove, and can be inserted straight into the clamping position without tipping over before being fixed.

[0035] Several clamping blocks 24 are placed in pairs or arranged in a ring around the sleeve placement ring 34.

[0036] In this embodiment, when clamping the sleeve, the forces acting on the sleeve are made to cancel each other out, preventing tipping caused by deviation forces.
