Description

Technical Field

[0001] The present invention relates to the technical field of guide wheel chain assembly production, and specifically to a fully automatic assembly production line for industrial hoisting guide wheel chains. Background Art

[0002] A chain is a mechanical product with strong versatility. Since it combines the characteristics of gears and belts, it has been widely used in transmission, conveying, and some special occasions. A chain is usually composed of chain links connected in sequence. Each chain link is composed of outer link plates, inner link plates, pins, rollers, and sleeves connected together. The outer link plates and inner link plates are both provided with through holes and are connected together by pins. Sleeves are installed outside the pins, and rollers are provided between the inner link plates to achieve transmission. The chains of suspension conveyors used for industrial hoisting are often double-guide wheel chains, which are generally composed of two types of chain links with wheel bodies installed alternately. The extending directions of the rotating shafts of the adjacent chain link wheel bodies often perpendicular to each other.

[0003] General assembly equipment can only use rivets to connect chain links. Once pins are used for connection, since iron parts for limiting need to be installed in the holes of the pins and bending operations need to be performed on the iron parts, this operation is often difficult for existing assembly machinery to complete and requires manual processing by personnel, resulting in limitations in the applicability of existing equipment and additional labor costs. Summary of the Invention

Two symmetrically arranged driving grooves are formed on the double-groove frame. The frame is fixedly connected with a circumferential guiding frame. Two sets of wheel frames are slidably connected to the circumferential guiding frame. The wheel frame is rotatably connected with a pressing wheel. The pressing wheel is used for rolling the iron wire that has been cut and inserted into the pin body. The wheel frame is fixedly connected with a protruding shaft slidably connected with the driving groove.

[0010] As a further improvement of the present invention: The pin body pushing mechanism includes an assembly frame fixedly connected to the base. The assembly frame is fixedly connected with a first motor. The output shaft of the first motor is fixedly connected with a second active telescopic rod. The second active telescopic rod is fixedly connected with a sleeve rotatably connected to the assembly frame.

The pin body pushing mechanism is used to insert the pin shaft into the hole where the first component and the second component are fitted. The wire supply part conveys the wire into the hole of the pin shaft. The wire passes through the through hole opened on the pin shaft and abuts against the wire supporting part. Then, the cutting part performs a cutting operation on the wire. The active telescopic frame pushes the frame to move towards the cut wire. Then, the first active telescopic rod is used to drive the double-groove frame to move. Driven by the driving groove in the double-groove frame, the protruding shaft drives the wheel frame to slide along the circumferential guide frame, so that the wheel frame drives the pressing wheel to rotate. At this time, the pressing wheel rolls the cut wire, so that the part of the cut wire extending outside the pin shaft is rolled and deformed by the pressing wheel, and the deformed wire fits against the outer wall of the pin shaft. If a rivet structure is used to connect the first component and the second component during assembly, after the first component and the second component are connected by the rivet, the hydraulic telescopic rod is used to drive the pressing head, so that the pressing head squeezes the rivet, so that the rivet is deformed, thereby completing the riveting operation of the first component and the second component. Through the cooperation of the pin body pushing mechanism, the wire supply and cutting mechanism, and the pressing and bending mechanism, the present invention automatically uses the pin shaft or rivet to connect and assemble the first component and the second component constituting the guide wheel chain, with strong applicability and labor saving.

Detailed implementation manners

[0033] The technical solution of the present invention will be further described in detail below in conjunction with specific embodiments.

[0034] Embodiment 1. Refer to Figures 1 to 14 As shown, an automatic assembly production line for industrial hoisting guide wheel chains includes a base 1. The base 1 is connected to a belt conveyor 2. The belt conveyor 2 is a conventional conveyor and will not be elaborated too much. A first component 3 is placed on the output belt of the belt conveyor 2, and a second component 4 is placed on the conveyor belt of the belt conveyor 2. It further includes:

[0035] Two groups of pin body pushing mechanisms 5 connected to the base 1;

[0036] A wire supply and cutting-off mechanism 6 connected to the base 1. The wire supply and cutting-off mechanism 6 includes a wire supply part 7 connected to the base 1. The wire supply part 7 is connected to a cutting part 8, and the cutting part 8 is used for cutting the wire 9.

[0037] Two groups of pressing and bending mechanisms 10 connected to the base 1. The pressing and bending mechanism 10 includes a fixed frame 11 fixedly connected to the base 1. The fixed frame 11 is fixedly connected to a hydraulic telescopic rod 12. The moving end of the hydraulic telescopic rod 12 is fixedly connected to a pressing head 13. The fixed frame 11 is fixedly connected to two groups of active telescopic frames 14. The moving ends of the two groups of active telescopic frames 14 are jointly fixedly connected to a frame 15. The frame 15 is fixedly connected to a wire supporting part 16. The frame 15 is connected to two groups of first active telescopic rods 17. The moving ends of the two groups of first active telescopic rods 17 are fixedly connected to a double-groove frame 18. The double-groove frame 18 is slidably connected to the frame 15. Two symmetrically arranged driving grooves 19 are formed on the double-groove frame 18. The frame 15 is fixedly connected to a circumferential guiding frame 20. Two wheel frames 21 are slidably connected to the circumferential guiding frame 20. A pressing wheel 22 is rotatably connected to the wheel frame 21. The pressing wheel 22 is used for rolling the wire 9 that has been cut and inserted into the pin body. The wheel frame 21 is fixedly connected to a protruding shaft 23 that is slidably connected to the driving groove 19.

[0038] During use, the output belt of the belt conveyor 2 is used to convey the docked first component 3 and second component 4. The pin body pushing mechanism 5 is used to insert a pin shaft into the hole where the first component 3 and the second component 4 are fitted. The wire supply section 7 conveys the wire 9 into the hole of the pin shaft. The wire 9 passes through the through hole formed in the pin shaft and abuts against the wire supporting section 16. Then, the cutting section 8 performs a cutting operation on the wire 9. The active telescopic frame 14 pushes the frame 15 to move towards the cut wire 9. Then, the first active telescopic rod 17 is used to drive the double groove frame 18 to move. Driven by the driving groove 19 in the double groove frame 18, the protruding shaft 23 drives the wheel frame 21 to slide along the circumferential guide frame 20, so that the wheel frame 21 drives the pressing wheel 22 to rotate. At this time, the pressing wheel 22 rolls on the cut wire 9, so that the part of the cut wire 9 extending outside the pin shaft is rolled and deformed by the pressing wheel 22, and the deformed wire 9 fits against the outer wall of the pin shaft. If a rivet structure is used to connect the first component 3 and the second component 4 during assembly, after the first component 3 and the second component 4 are connected by the rivet, the hydraulic telescopic rod 12 is used to drive the pressing head 13, so that the pressing head 13 squeezes the rivet, so that the rivet is deformed, thereby completing the riveting operation of the first component 3 and the second component 4. Through the cooperation of the pin body pushing mechanism 5, the wire supply and cutting mechanism 6, and the pressing and bending mechanism 10, the present invention automatically uses a pin shaft or a rivet to connect and assemble the first component 3 and the second component 4 that form the guide wheel chain, which has strong applicability and saves manpower.

[0039] In one case of this embodiment, the pin pushing mechanism 5 includes an assembly frame 24 fixedly connected to the base 1, the assembly frame 24 is fixedly connected to a first motor 25, the output shaft of the first motor 25 is fixedly connected to a second active telescopic rod 26, the second active telescopic rod 26 is fixedly connected to a sleeve 27 rotatably connected to the assembly frame 24, the end of the second active telescopic rod 26 away from the first motor 25 is fixedly connected to an electromagnet 28, the assembly frame 24 is fixedly connected to a baffle plate 29, the baffle plate 29 is fixedly connected to a second motor 30, and the output shaft of the second motor 30 is fixedly connected to the second active telescopic rod 26. A rotating frame 31 is fixedly connected to the output end, and the rotating frame 31 is fixedly connected to multiple groups of tube bodies 32. When the rotating frame 31 drives the tube body 32 to rotate, the tube body 32 and the baffle plate 29 are periodically dislocated and separated. When the tube body 32 is not separated from the baffle plate 29, the tube body 32 and the baffle plate 29 abut against each other. Multiple groups of blocks 33 are hinged in the tube body 32, and the block block 33 is coaxially connected with a torsion spring 34. One end of the torsion spring 34 away from the block block 33 is fixedly connected to the inner wall of the tube body 32. An observation window 35 is opened on the tube body 32, and the baffle plate 29 is fixedly connected to a camera 36 through a support plate. The tube body 32 is used to accommodate a pin or a rivet, and the block 33 blocks the round head of the pin or the round head of the rivet and cooperates with the baffle plate 29 to shield the tube body 32 away from the belt conveyor 2 to limit the free movement of the pin or the rivet. The camera 36 photographs the pin in the tube body 32 through the observation window 35, and the photographed image is transmitted to the remote control center for analysis. When the hole on the pin is not facing the observation window 35, the electromagnet 28 is energized, and the second active telescopic rod 26 drives the electromagnet 28 to move toward the tube body 32, so that the pin is magnetically attracted by the electromagnet 28, and then the first motor 25 drives the second active telescopic rod 26 to rotate, so that the electromagnet 28 rotates to adjust the orientation position of the hole of the pin. The second active telescopic rod 26 pushes the electromagnet 28 so that the electromagnet 28 pushes the pin or rivet in the tube body 32, and the block 33 is pressed and rotated. At this time, the pin or rivet moves along the tube body 32 to the connection between the first component 3 and the second component 4.

[0040] In a case of this embodiment, the wire supply unit 7 includes two groups of fourth active telescopic rods 52 connected to the base 1. The moving end of the fourth active telescopic rod 52 is fixedly connected with a suspension 37. The suspension 37 is placed above the belt conveyor 2. The suspension 37 is fixedly connected with a double-output shaft motor 38. The output end of the double-output shaft motor 38 is fixedly connected with a lead screw 39. The lead screw 39 is threadedly connected with a hanger 40 slidably connected to the suspension 37. The hanger 40 is fixedly connected with a protective cover 41. The protective cover 41 is fixedly connected with a third motor 42. The output end of the third motor 42 is fixedly connected with a winding wheel 43. A wire 9 is wound around the winding wheel 43. The protective cover 41 is fixedly connected with a wire conduit 44. The wire conduit 44 is slidably connected with the wire 9. The wire conduit 44 is connected to the cutting part 8. The fourth active telescopic rod 52 is used to adjust the height of the suspension 37. The driving lead screw 39 rotates by the double-output shaft motor 38. The rotating lead screw 39 drives the hanger 40 to move along the suspension 37. The hanger 40 drives the protective cover 41 to move. The protective cover 41 drives the third motor 42 to move. As the height of the protective cover 41 decreases, the wire 9 in the protective cover 41 gradually approaches the belt conveyor 2. The third motor 42 drives the winding wheel 43 to rotate. The wire 9 released by the winding wheel 43 moves along the wire conduit 44 towards the hole of the pin, and then the cutting part 8 is used to cut the wire 9.

[0041] In a case of this embodiment, the cutting part 8 includes a power box 45 fixedly connected to the wire conduit 44. The power box 45 is fixedly connected with a third active telescopic rod 46. The moving end of the third active telescopic rod 46 is fixedly connected with a tool rest 47 slidably installed in the power box 45. The tool rest 47 is fixedly connected with a blade 48. The third active telescopic rod 46 drives the tool rest 47 to move. The moving tool rest 47 drives the blade 48 to move. The blade 48 is used to cut the wire 9.

[0042] In a case of this embodiment, a feed opening 49 is formed in the lower part of the baffle 29. When the rotating frame 31 drives a plurality of pipe bodies 32 to rotate, the feed opening 49 is periodically aligned with the pipe bodies 32. By providing the feed opening 49, it is convenient to install pins or rivets into the pipe bodies 32.

[0043] In a case of this embodiment, the pressing wheel 22 is movably connected to the second component 4. By pressing the second component 4 with the pressing wheel 22, the second component 4 is prevented from moving when installing pins or rivets.

[0044] Embodiment 2, on the basis of Embodiment 1, refer to Figure 8 、 Figure 9 、 Figure 10, the wire supporting part 16 includes an L-shaped frame 50 fixedly connected to the frame 15, and the L-shaped frame 50 is fixedly connected with a bottom supporting frame 51. The bottom supporting frame 51 is used for supporting the cut wire 9 to prevent the cut wire 9 from slipping off the pin shaft.

[0045] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
