Description

Technical Field

[0001] The present invention belongs to the technical field of building material component assembly, and particularly relates to an automatic assembly machine for threaded rods. Background Art

[0002] Scaffolds are necessities during the construction process. In the process of erecting scaffolds, top supports are often used. Since the top support can adjust the height at which the top of the scaffold contacts the bottom of the top beam, the top support plays a very important role in engineering projects; the top support includes a top support base, a threaded rod, and a double-wing adjustment disc. The top end of the threaded rod is fixedly connected to the bottom end of the top support base, and the double-wing adjustment disc is threadedly connected to the screw rod. When in use, the threaded rod is inserted into the steel pipe of the scaffold, so that the double-wing adjustment disc abuts against the steel pipe of the scaffold, and then the double-wing adjustment disc is rotated to adjust the height of the top support base, which is used to support an object.

[0003] For example, the patent document with the patent number CN202122706031.7 discloses a quick screwing-in device for adjustable supports of disc-type scaffold top supports and flat supports. By a construction worker holding the power mechanism and connecting the power mechanism and the rotating head as a whole, then placing the disc-type scaffold top support on the ground and placing the adjustable support above the disc-type scaffold top support, stepping on the bottom of the disc-type scaffold top support with one foot, and then the construction worker holds the power mechanism again, picks up the screwing-in mechanism, vertically inserts the middle rod of the screwing-in mechanism into the disc-type scaffold top support, and places its two side rods on both sides of the adjustable support respectively. Then the construction worker turns on the power mechanism, so that the power mechanism rotates, driving the screwing-in mechanism and the adjustable support to rotate in sequence, and finally screwing the adjustable support quickly into the predetermined installation height of the disc-type scaffold top support. Then the construction worker vertically pulls out the screwing-in mechanism; this screwing-in device only drives the rotation of the double-wing adjustment disc, and the positioning of the threaded rod and the docking of the threaded rod and the double-wing adjustment disc are all completed manually. The degree of automation is low, the installation efficiency is low, the manual labor intensity is high, and it cannot meet the usage requirements. Summary of the Invention

When the front-end manipulator 35 clamps the threaded rod 10 on the material receiving seat 14, the corresponding assembly device 5, the creasing machine 7, and the burr cleaning device 8 all have corresponding manipulators 35 clamping the threaded rod 10. When the front-end manipulator 35 transfers the clamped threaded rod 10 and places it on the assembly device 5, the other three manipulators 35 keep in sync and place the corresponding threaded rod 10 on the creasing machine 7, the burr cleaning device 8 and the finished product storage rack 6. The manipulators 35 keep in sync, which is conducive to improving work efficiency.

[0039] The double-wing adjustment disk storage device 4 is an upright limiting cylinder, a limiting groove 41 matching the threaded sleeve of the double-wing adjustment disk is provided in the middle of the limiting cylinder, limiting slots 42 matching the double wings of the double-wing adjustment disk are provided on both sides of the limiting cylinder, to ensure that the bottom double-wing adjustment disk in the double-wing adjustment disk storage device 4 remains in a horizontal state, a limiting rod 52 extends into the double-wing adjustment disk storage device 4, and the limiting rod 52 supports the double-wing adjustment disk to ensure that the lowest double-wing adjustment disk remains in a horizontal state, so as to facilitate the limiting support of the double-wing adjustment disk by the limiting rod 52.

[0040] The support seat 51 includes a cylinder 511 and a limit seat 512. The cylinder 511 is upright mounted on the assembly workbench 2, and the limit seat 512 is mounted on the cylinder 511. The limit seat 512 is provided with a limit groove matching the threaded rod. When the pushing and pressing device 53 and the pressing rotating device 54 press the double-wing adjustment disk and the threaded rod, the cylinder 511 retracts to avoid interference between the limit seat 512 and the double-wing adjustment disk during the assembly process.

[0041] Working process:

[0042] Manually place the threaded rod in the U-shaped limit groove 13 and convey it forward through the chain conveyor 12. Lift the threaded rod 10 by the arc-shaped panel to disengage the threaded rod 10 from the limit of the U-shaped limit groove 13. The threaded rod 10 slides into the receiving seat 14 along the arc-shaped panel to ensure smooth sliding of the threaded rod 10. Push the threaded rod 10 by adjusting the cylinder 17 so that one end of the threaded rod 10 contacts the support limit plate 16. The pre-positioning of the threaded rod 10 is achieved through the support limit plate 16 and the adjusting cylinder 17 to ensure the position accuracy of the threaded rod 10 during feeding and ensure that the threaded rod clamping device 3 can accurately clamp. After clamping the threaded rod by the threaded rod clamping device 3, place it on the support seat 51. The material pushing and pressing device 53 pushes out the double-wing adjusting disc and docks it with the threaded rod. At this time, the double-wing adjusting disc and the threaded rod are tightened by the material pushing and pressing device 53 and the pressing and rotating device 54. The pressing and rotating device 54 rotates, and under the limiting state of the limiting rod 52 on the double-wing adjusting disc, the double-wing adjusting disc is screwed onto the threaded rod. After clamping the threaded rod completed with assembly on the assembly device 5 by the threaded rod clamping device 3, place it on the support device 71. Push the threaded rod by the top push cylinder 73 so that one end of the threaded rod abuts against the limit block 72 for positioning. The hydraulic cylinder 74 drives the pressing block 75 to press an indentation on the threaded rod to avoid the double-wing adjusting disc from slipping out of the threaded rod by damaging the thread on the threaded rod. After clamping the threaded rod completed with pressing and cutting on the indentation machine 7 by the threaded rod clamping device 3, place it on the support plate 81. Push the cleaning sleeve 85 to extend by the telescopic cylinder 84. The cleaning sleeve 85 pushes the threaded rod onto the top plate 82 for support. The cleaning sleeve 85 continues to extend. The cleaning sleeve 85 cleans and flattens the burrs higher than the thread formed on the threaded rod during the indentation by the indentation machine 7. When the cleaning sleeve 85 retracts reversely and exits the threaded rod, the threaded rod is supported by the top shaft 83 to ensure that the cleaning sleeve 85 can exit relative to the threaded rod, avoiding the problem that the threaded rod cannot smoothly exit the cleaning sleeve 85 due to interference fit, and ensuring that the threaded rod and the docking sleeve can be smoothly assembled during later use. After clamping the threaded rod completed with cleaning on the burr cleaning device 8 by the threaded rod clamping device 3, place it on the finished product storage rack 6. When the frontmost manipulator 35 clamps the threaded rod 10 on the receiving seat 14, corresponding manipulators 35 clamp the threaded rod 10 at the corresponding stations of the assembly device 5, the indentation machine 7, and the burr cleaning device 8. When the frontmost manipulator 35 transfers and places the clamped threaded rod 10 on the assembly device 5, the other three manipulators 35 synchronously place the corresponding threaded rods 10 on the indentation machine 7, the burr cleaning device 8, and the finished product storage rack 6. Each manipulator 35 moves synchronously, which is beneficial to improving work efficiency; it can achieve the positioning of the threaded rod and the docking and screwing of the threaded rod and the double-wing adjusting disc. The assembly work is coherent, with a high degree of automation, high installation efficiency, and no need for manual assistance during the assembly process, which is beneficial to reducing the labor intensity of workers and the labor cost, and can meet the usage requirements of the top support in construction.
