Description

Technical Field

[0001] This invention relates to the field of manual chain hoist manufacturing equipment technology, specifically to an automated processing device for manual chain hoist chains. Background Technology

[0002] A hand chain hoist, also known as a "magic hoist," "unbreakable chain hoist," or "manual hoist," is a simple and portable manual lifting machine, also called a "ring chain hoist" or "chain reversing hoist." It is suitable for short-distance lifting of small equipment and goods, with a lifting capacity generally not exceeding 100 tons. The outer shell of the hand chain hoist is made of high-quality alloy steel, making it sturdy, wear-resistant, and highly safe. When lifting a heavy object, pulling the manual chain clockwise rotates the hand chain wheel; when lowering, pulling the manual chain counterclockwise separates the brake seat from the brake pads, causing the ratchet to stop under the action of the pawl. The five-tooth long shaft drives the lifting chain wheel to run in the opposite direction, thus smoothly lowering the heavy object. In the manufacturing process of hand chain hoists, they are commonly used lifting tools. A hand chain hoist has two sets of chains: a lifting chain and a manual chain, both composed of several ring-shaped steel bars connected in series.

[0003] In the welding process of hand chain hoist chain processing, it is currently necessary to manually push the chain links into the welding equipment and weld each link individually. The entire chain has hundreds of links, which takes a lot of time and has extremely low welding efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an automated processing device for hand chain hoist chains, solving the problem of low chain welding efficiency caused by manual placement of chain links.

A low voltage and high current are passed instantaneously between the chain links to be welded between the two electrode heads, so that the contact surfaces of the two mating contact heads of the chain links are instantly heated to melt and fuse. Furthermore, the pressure is continuously applied by the extension of the cylinder, which can form an upsetting effect and improve the welding strength of the chain links.

[0009] Preferably, a fixed limiting plate and a sliding limiting plate are respectively provided on both sides of the mounting plate, and a through opening is provided on the surface of the frame corresponding to the sliding limiting plate. One end of the fixed limiting plate is fixedly connected to the frame, and a cylinder is fixedly connected to the inner side wall of the frame. One end of the sliding limiting plate passes through the through opening and is fixedly connected to the driving end of the cylinder.

[0010] Preferably, the two ends of the chain are respectively inserted into two support columns, and a fixed support plate and a sliding support plate are respectively provided on both sides of the chain. The bottom end of the fixed support plate is fixedly connected to the flipping frame, and the bottom end of the sliding support plate is slidably connected to the flipping frame. A cylinder four is provided on one side of the sliding support plate and is fixedly connected to the flipping frame. The driving end of the cylinder four is fixedly connected to the sliding support plate.

[0011] Preferably, the sliding support plate includes a base plate, with telescopic rods fixedly connected to both sides of the base plate, and a top plate fixedly connected to the top ends of the two telescopic rods. An L-shaped connector is slidably connected to the center of the base plate, and an elastic element is fixedly connected between the inner side wall of the connector and the side wall of the base plate. A triangular push block is fixedly connected to the upper surface of the connector.

[0012] Preferably, a limiting frame is provided directly above the fixed support plate, and T-shaped guide rods are respectively provided through both ends of the limiting frame. The bottom end of the guide rod is fixedly connected to the flipping frame. An elastic element is sleeved on the area of ​​the guide rod below the limiting frame, and several compression rods are fixedly connected to the upper surface of the limiting frame.

[0013] Preferably, the chain support assembly further includes several extrusion plates, the bottom end of which is fixedly connected to the base, and the top end of which has an inclined surface facing one corner of the flipping frame.

[0014] Preferably, mounting platforms are fixedly connected to both sides of the sliding support plate, and anti-detachment rods are fixedly connected to the side walls of the mounting platforms.

[0015] Preferably, the upper sidewall of the support column is provided with a slot, the slot is located at the movement trajectory of the anti-detachment rod, and the lower surface of the anti-detachment rod is in contact with the upper surface of the horizontal chain link.

[0016] Working principle: The electric slide moves the mounting frame, which then moves sequentially to the horizontal chain links. Cylinder 1 extends, inserting two electrode heads into both sides of the chain link. Cylinder 2 then pushes the insulating base towards the chain link, allowing the electrode heads to contact the link and apply current for resistance welding of the joint. After welding, cylinders 1 and 2 retract sequentially, removing the electrode heads from the chain. The electric slide then moves the electrode heads to the next set of horizontally distributed chain links, repeating the above steps. After all horizontal chain links are welded, the motor rotates the tilting frame 90°, bringing the unwelded chain links to a horizontal position, allowing for comprehensive welding of all chain links.

[0017] This invention provides an automated processing device for hand chain hoist chains. It has the following beneficial effects:

[0018] 1. This invention straightens the chain by inserting both ends of the chain to be welded into two support columns and pressing against the protrusion below. Then, the welding assembly is moved by an electric slide to weld the horizontal chain links in sequence. After welding is completed, the motor drives the tilting frame to rotate 90°, so that the unwelded chain links are rotated to a horizontal state. This allows for comprehensive welding of the chain links. Moreover, the chain links are welded automatically without manual operation, which greatly improves the welding effect of the chain.

[0019] 2. The present invention supports and limits the vertical and horizontal chain links by using a fixed support plate and a sliding support plate, so that the chain remains in a fixed position after installation so that the welding components can be accurately connected. At the same time, it can distribute the weight of the chain and prevent the chain from bending due to gravity.

[0020] 3. The present invention provides elastic support through three pairs of elastic limit frames, so that the limit frames are higher than the fixed support plate, so as to place or remove the chain. When the flipping frame flips, the limit frames can replace the sliding support plate to stably limit and support the rotated chain, so that the chain can remain stable and not shake after rotation.

[0021] 4. When the sliding support plate of the present invention moves to limit the chain, it drives the anti-detachment rod to move into the slot, so that the anti-detachment rod cooperates with the support column and the protrusion to limit the chain links at both ends of the chain and prevent the chain from falling off when it is flipped.

[0032] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1, please refer to the appendix. Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 5 This invention provides an automated processing device for a hand chain hoist chain, comprising a base 1 and a chain. A U-shaped support frame 2 is fixedly connected to the top of the base 1. A tilting frame 3 is rotatably connected inside the support frame 2 via a shaft. A motor 4 is fixedly connected to the upper side wall of the support frame 2, and the drive end of the motor 4 is fixedly connected to the shaft of the tilting frame 3. A chain support assembly 5 is mounted on the surface of the tilting frame 3. The chain support assembly 5 includes two support columns 501 located on both sides of the tilting frame 3. An annular protrusion 502 is fixedly provided on the outer wall of the support column 501. The upper surface of the base 1 is fixedly connected to... An electric slide table 6 is connected to the slide block of the electric slide table 6, and a cylinder 7 is fixedly connected to the slide block of the cylinder 7. A welding assembly 8 is installed on the drive end of the cylinder 7. The welding assembly 8 includes a mounting frame 81, which is fixedly connected to the drive end of the cylinder 7. Two sets of cylinders 82 are hinged to both sides of the mounting frame 81. An insulating base 83 is hinged to the drive end of each of the two cylinders 82. One end of the insulating base 83 is slidably connected to the mounting frame 81. An electrode head 84 is fixedly connected to the side wall of the insulating base 83. The electrode head 84 is made of copper substrate, and the two electrode heads 84 are respectively connected to the positive and negative terminals of the power supply.

[0034] Specifically, the two ends of the chain to be welded are inserted into the two support posts 501 and pressed against the protrusions 502 below, thereby straightening the chain. After the chain is straightened, the distribution of adjacent chain links will be nearly vertical. Then, the electric slide table 6 drives the mounting frame 81 to move, so that the mounting frame 81 moves sequentially to the horizontal chain link. The cylinder 7 extends, so that the two electrode heads 84 are inserted into both sides of the chain link. Then, the cylinder 82 moves to push the insulating base 83 to slide towards the chain link, so that the electrode head 84 presses against the chain link and is energized. Resistance welding of the joint is achieved. After welding is completed, cylinders 82 and 7 retract sequentially, causing electrode head 84 to exit the chain. The electric slide 6 moves electrode head 84 to the next set of horizontally distributed chain links and repeats the above operation steps. After all horizontal chain links are welded, motor 4 drives the tilting frame 3 to rotate 90°, so that the unwelded chain links are rotated to a horizontal state. This allows for comprehensive welding of the chain links. Moreover, the chain links are welded automatically without manual operation, which greatly improves the welding effect of the chain.

[0035] Example 2, please refer to the appendix. Figure 7 Since the contact between the chain links during welding will form a conductive path or a heat conduction path, it will interfere with the stability of the welding arc and the weld formation. In order to solve the above problems, this embodiment provides the following technical solution: the bottom end of a set of support columns 501 is fixedly connected to the flipping frame 3. A sliding groove is provided on the surface of the flipping frame 3 corresponding to another set of support columns 501. A sliding member 506 is slidably connected inside the sliding groove. The bottom end of the other set of support columns 501 is fixedly connected to the sliding member 506. A tension spring 507 is fixedly connected to the side wall of the sliding member 506. The end of the tension spring 507 away from the sliding member 506 is fixedly installed inside the sliding groove.

[0036] Specifically, the tension spring 507 applies tension to the sliding member 506, thereby elastically straightening the chain after it is connected to the support column 501, while allowing displacement range for the subsequent sliding support plate 504 to pull the chain link to move.

[0037] Please see the appendix Figure 5 A fixed support plate 503 and a sliding support plate 504 are respectively provided on both sides of the chain. The bottom end of the fixed support plate 503 is fixedly connected to the flipping frame 3, and the bottom end of the sliding support plate 504 is slidably connected to the flipping frame 3. A cylinder 505 is provided on one side of the sliding support plate 504 and is fixedly connected to the flipping frame 3. The drive end of the cylinder 505 is fixedly connected to the sliding support plate 504.

[0038] Specifically, when placing the chain to be processed, the cylinder 505 retracts, causing the sliding support plate 504 to slide, increasing the distance between the fixed support plate 503 and the sliding support plate 504 to facilitate chain placement. Then, the vertical chain link is placed against the fixed support plate 503, while the horizontal chain link is placed at the top of the fixed support plate 503. Subsequently, the cylinder 505 moves, causing the sliding support plate 504 to slide to one side of the fixed support plate 503 until it is against the other side of the vertical chain link and moves below the horizontal chain link. Thus, the fixed support plate 503 and the sliding support plate 504 support and limit the vertical and horizontal chain links, ensuring the chain links remain stable at horizontal or vertical to prevent deflection and allow for precise docking of the welding assembly 8. Simultaneously, it disperses the chain's weight, reducing the tension on the tension spring 507.

[0039] Please see the appendix Figure 3 and attached Figure 4The mounting bracket 81 includes a square frame 801. A slot 802 is formed on the surface of the frame 801. A T-shaped mounting plate 804 is slidably connected to the slot 802. An elastic element 803 is provided inside the slot 802. The elastic element can be a steel leaf spring, a coil spring, a torsion bar spring, a rubber spring, etc., preferably a coil spring. The two ends of the elastic element 803 are fixedly connected to the slot 802 and the mounting plate 804, respectively. The mounting plate 804 is used to install a cylinder 82 and an insulating base 83. A fixed limiting plate 85 and a sliding limiting plate 86 are provided on both sides of the mounting plate 804, respectively. A through-hole is formed on the surface of the frame 801 corresponding to the sliding limiting plate 86. One end of the fixed limiting plate 85 is fixedly connected to the frame 801. A cylinder 87 is fixedly connected to the inner side wall of the frame 801. One end of the sliding limiting plate 86 passes through the through-hole and is fixedly connected to the driving end of the cylinder 87. The sliding limiting plate 86 is slidably connected to the through-hole.

[0040] Specifically, the elastic force applied to the mounting plate 804 by the elastic element 803 pushes the mounting plate 804 to slide to one side of the slot 802, so that the two electrode heads 84 are symmetrically distributed along the vertical center line of the mounting frame 81. During welding, the cylinders 7 and 82 move in coordination with the electric slide 6, so that the two electrode heads 84 respectively abut against the two sides of the horizontal chain link. At this time, the fixed limiting plate 85 moves to fit against the outer wall of the vertical chain link on the adjacent side of the horizontal chain link, and the sliding limiting plate 86 moves to the outer side of the adjacent vertical chain link on the other side of the horizontal chain link. Then, the cylinder 87 retracts. The cylinder 87 retracts, causing the sliding limit plate 86 to slide and push the adjacent vertical chain link a distance toward the horizontal chain link, thereby disengaging the vertical chain link from the horizontal chain link. Subsequently, the sliding limit plate 86 pushes the mounting plate 804 to move. Since the electrode head 84 on the mounting plate 804 has clamped the horizontal chain link, the mounting plate 804 synchronously drives the horizontal chain link to move, causing the horizontal chain link to be misaligned with the vertical chain link adjacent to the fixed limit plate 85. This prevents the chain link to be welded from contacting the adjacent chain link during welding, improving the stability of the welding arc and the quality of the weld formation.

[0041] Based on the above embodiments, please refer to the appendix. Figure 5 and attached Figure 8Because the chain is relatively heavy when it is placed, it cannot be accurately kept perpendicular to each other by relying solely on the tension of the tension spring 507 and the support plate 503. This affects the insertion of the sliding support plate 504 into its bottom when the horizontal chain is tilted. To solve this problem, this embodiment proposes the following technical solution: The sliding support plate 504 includes a base plate 5041. Telescopic rods 5042 are fixedly connected to both sides of the base plate 5041. The top ends of the two telescopic rods 5042 are fixedly connected to a top plate 5043. An L-shaped connector 5044 is slidably connected to the center of the base plate 5041. An elastic element 5045 is fixedly connected between the inner side wall of the connector 5044 and the side wall of the base plate 5041. A triangular push block 5046 is fixedly connected to the upper surface of the connector 5044. The connector 5044 is connected to the drive end of the cylinder 505.

[0042] Specifically, the elastic force of the elastic element 5045 pushes the base plate 5041 to slide, causing the base plate 5041 to drive the top plate 5043 above to slide, thereby misaligning the top plate 5043 with the push block 5046, achieving the effect of lowering the height of the top plate 5043 so that it can be inserted under the inclined chain link. When the sliding support plate 504 moves to the bottom of the chain link, the reaction force generated by the base plate 5041 resisting the vertical chain link causes the connecting element 5044 to gradually insert the push block under the top plate 5043 and push the top plate 5043 upward, thereby increasing the height of the top plate 5043, so that the top plate 5043 can straighten the inclined chain link and keep it horizontal.

[0043] Based on the above embodiments, please refer to the appendix. Figure 9 A limiting frame 508 is provided directly above the fixed support plate 503. T-shaped guide rods 509 are respectively provided through both ends of the limiting frame 508. The bottom end of the guide rod 509 is fixedly connected to the flipping frame 3. An elastic element 510 is sleeved in the area of ​​the guide rod 509 below the limiting frame 508. Several pressing rods 511 are fixedly connected to the upper surface of the limiting frame 508. The pressing rod 511 is composed of a rod and a ball bearing at one end of the rod. The chain support assembly 5 also includes several pressing plates 512. The bottom end of the pressing plate 512 is fixedly connected to the base 1. The top end of the pressing plate 512 has an inclined surface facing one corner of the flipping frame 3. The inclined surface is located on the moving trajectory of the pressing rod 511.

[0044] Specifically, the limiting frame 508 is elastically supported by the elastic element 510, making the limiting frame 508 higher than the fixed support plate 503, so as to place or remove the chain. When the flipping frame 3 flips, it drives the pressing rod 511 to move along the inclined plane. The pressing plate 512 restricts the pressing rod 511 to move the limiting frame 508 to one side of the fixed support plate 503 until it fits the chain. Thus, when the flipping frame 3 rotates 90°, the limiting frame 508 can replace the sliding support plate 504 to stably limit and support the rotated chain. Then, the cylinder 505 retracts and drives the sliding support plate 504 to rise to leave processing space, so that the chain remains stable after flipping, which helps the welding assembly 8 to be accurately welded.

[0045] Example 3, please refer to the appendix. Figure 7 The chain is prone to detaching from the support column 501 due to its weight during rotation. To solve the above problem, this embodiment provides the following technical solution: mounting platforms 513 are fixedly connected to both sides of the sliding support plate 504, and anti-detachment rods 514 are fixedly connected to the side walls of the mounting platforms 513. A slot 515 is opened on the upper side wall of the support column 501. The slot 515 is located at the movement trajectory of the anti-detachment rod 514. The lower surface of the anti-detachment rod 514 is in contact with the upper surface of the horizontal chain link. A certain gap is left between the mounting platform 513 and the end of the chain to allow the insertion of the electrode head 84.

[0046] Specifically, when the sliding support plate 504 moves to limit the chain, it simultaneously drives the two mounting platforms 513 to move to the outside of both ends of the chain, and drives the anti-detachment rod 514 to move into the inside of the slot 515, thereby cooperating with the support column 501 and the protrusion 502 to limit the chain links at both ends of the chain and prevent the chain from falling off when it is flipped.

[0047] In the workflow, when placing the chain to be processed, the cylinder 505 retracts, causing the sliding support plate 504 to slide, increasing the distance between the fixed support plate 503 and the sliding support plate 504 to facilitate chain placement. Then, the vertical chain link is placed against the fixed support plate 503, and the horizontal chain link is placed at the top of the fixed support plate 503. Subsequently, the cylinder 505 moves, causing the sliding support plate 504 to slide to one side of the fixed support plate 503 until the sliding support plate 504 is against the other side of the vertical chain link. By moving it below the horizontal chain link, the fixed support plate 503 and the sliding support plate 504 support both the vertical and horizontal chain links, allowing the chain links to remain stably horizontal or vertical for precise docking of the welding assembly 8.

[0048] During welding, cylinders 7 and 82, along with the electric slide 6, move in coordination, causing the two electrode heads 84 to abut against the two sides of the horizontal chain link. At this point, the fixed limiting plate 85 moves to fit against the outer wall of the vertical chain link adjacent to the horizontal chain link. The sliding limiting plate 86 moves to the outer side of the adjacent vertical chain link on the other side of the horizontal chain link. Then, cylinder 87 retracts, causing the sliding limiting plate 86 to slide and push the adjacent vertical chain link a distance towards the horizontal chain link, thus disengaging the vertical chain link from the horizontal chain link. Subsequently, the sliding limiting plate 86 pushes the mounting plate 804 to move. Since the electrode heads 84 on the mounting plate 804 have clamped the horizontal chain link, this movement causes the horizontal chain link to move, thus... The horizontal chain links are staggered from the vertical chain links adjacent to the fixed limiting plate 85, so that the chain links to be welded do not come into contact with adjacent chain links during welding, thereby improving the stability of the welding arc and the quality of the weld formation. After welding is completed, cylinders 82 and 7 retract in sequence, causing the electrode head 84 to exit the chain. The electric slide table 6 moves the electrode head 84 to the next set of horizontally distributed chain links and repeats the above operation steps. After all the horizontal chain links are welded, the motor 4 drives the flipping frame 3 to rotate 90°, so that the unwelded chain links rotate to a horizontal state. Thus, the electrode head 84 can weld the chain links comprehensively. Moreover, the chain links are welded automatically without manual operation, which greatly improves the welding effect of the chain.

[0049] The limiting frame 508 is elastically supported by the elastic element 510, so that the limiting frame 508 is higher than the fixed support plate 503, so as to place or remove the chain. When the flipping frame 3 flips, it drives the pressing rod 511 to move along the inclined plane. The pressing plate 512 restricts the pressing rod 511 to move the limiting frame 508 to one side of the fixed support plate 503. When the flipping frame 3 rotates 90°, the limiting frame 508 can replace the sliding support plate 504 to stabilize and support the chain after rotation. Then the cylinder 505 retracts and drives the sliding support plate 504 to rise to leave processing space, so that the chain remains stable after flipping, which helps the welding assembly 8 to be accurately welded.

[0050] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
