Description

Technical Field

[0001] This utility model relates to the field of suspended conveyor technology, and in particular to a workpiece anti-sway device for a suspended assembly production line. Background Technology

[0002] Suspended assembly lines are continuous conveying equipment widely used in industries such as automotive, home appliances, and machinery manufacturing. Their basic structure typically includes a suspended rail fixed above the factory building, multiple spaced traveling frames mounted on the rail, and chains connecting the traveling frames. Driven by the chains, the traveling frames can move continuously along the suspended rail. Hooks or clamps are usually installed below the traveling frames to suspend and transport workpieces, thereby enabling continuous transfer and assembly of workpieces between different workstations.

[0003] In existing suspended assembly lines, suspended workpieces are prone to swaying during operation. This is mainly due to the following reasons: First, the workpieces are suspended by hooks or chains, and their structural characteristics are similar to a pendulum system with low inherent damping. Once subjected to external forces, they are prone to oscillation and are difficult to naturally decay in a short time. Second, the production line generates significant inertial forces acting on the workpieces during start-up, stopping, acceleration, and deceleration, leading to an increase in the amplitude of workpiece swaying.

[0004] Excessive swaying of workpieces during transport can not only reduce production cycle time and assembly accuracy, but may also cause workpieces to collide and scratch each other, and even interfere with the safety of operators when passing through critical workstations. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where excessive swaying of workpieces during the conveying process not only reduces production cycle time and assembly accuracy, but may also cause workpieces to collide and scratch each other, or even interfere with the safety of operators when passing through critical workstations. Therefore, this invention proposes a workpiece anti-sway device for a suspended assembly production line.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A workpiece anti-sway device for a suspended assembly production line includes a traveling frame rod with a hook for hooking the workpiece suspended below the traveling frame rod. A positioning seat is fixedly installed on the traveling frame rod. Two pressure rods that can swing up and down are symmetrically rotatably connected to both sides of the positioning seat. Each pressure rod is slidably connected to a slider. A pull rod is movably connected between the sliders of the two pressure rods. Pushing and pulling the pull rod up and down can change the angle between the two pressure rods.

[0008] A pressure plate is installed on the inner side of the end of the pressure rod away from the positioning seat.

[0009] The pressure rod is rotatably connected to the positioning seat via a first hinge.

[0010] The two sides of the pull rod are rotatably connected to the slider via second hinges.

[0011] The slider is connected to the damping of the pressure rod.

[0012] A locking mechanism is provided between the pull rod and the first rod portion. The locking mechanism includes a support rod that is rotatably connected to the pull rod via a third hinge. A friction block is connected to the end of the support rod. A first spring is installed between the support rod and the pull rod. The first spring can apply a thrust to the support rod against the first rod portion.

[0013] Two locking mechanisms are provided symmetrically, and a rope is connected between the support rods of the two locking mechanisms.

[0014] The pressure rod includes a first rod section, a second spring, and a second rod section connected in sequence, with a pressure plate installed on the inner side of the second rod section.

[0015] This invention proposes a workpiece anti-sway device for a suspended assembly line. The advantages are as follows: This device uses a fixed positioning seat on the traveling frame's suspension rod and symmetrically installed pressure rods. Synchronous clamping is achieved through the linkage of the slider and the pull rod, providing double-sided support to the workpiece while it is suspended by the hook. This structure significantly reduces the lateral sway and rotation of the workpiece during transport, preventing collisions and positional deviations between workpieces, thereby improving the stability and accuracy of the assembly process and ensuring safer and more reliable production line operation.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-2A workpiece anti-sway device for a suspended assembly production line includes a traveling frame rod 1, with a hook 2 for hooking the workpiece suspended below the traveling frame rod 1. A positioning seat 3 is fixedly installed on the traveling frame rod 1. Two pressure rods 5 that can swing up and down are symmetrically rotatably connected on both sides of the positioning seat 3. Each pressure rod 5 is slidably connected to a slider 7. A pull rod 8 is movably connected between the sliders 7 of the two pressure rods 5. Pushing and pulling the pull rod 8 up and down can change the angle between the two pressure rods 5.

[0021] The workpiece is suspended below the traveling frame rod 1 by the hook 2. The positioning seat 3 is fixed to the traveling frame rod 1, and two pressure rods 5 are symmetrically rotatably connected to both sides of the positioning seat 3. The two pressure rods 5 can swing relative to each other. Each pressure rod 5 is slidably connected to a slider 7, and a pull rod 8 is movably connected between the two sliders 7. In use, the operator pushes or pulls the pull rod 8 downwards. The pull rod 8 drives the two sliders 7 to slide along the pressure rods 5. The movement of the sliders 7 forces the pressure rods 5 to retract around the rotation point of the positioning seat 3 towards the workpiece, so that the two pressure rods 5 simultaneously clamp the workpiece, thus providing additional support while the workpiece is suspended by the hook 2. When the pull rod 8 is released, the pressure rods 5 return to their original position, and the workpiece is released from clamping.

[0022] By setting a positioning seat 3 on the traveling frame suspension rod 1 and symmetrically arranging two pressure rods 5, and then using the linkage mechanism of the slider 7 and the pull rod 8 to achieve synchronous clamping, multi-point support can be provided for the workpiece during the suspension and conveying process, effectively reducing the free swing amplitude of the workpiece. After the workpiece is initially suspended on the hook 2, it is then symmetrically clamped by the two pressure rods 5, which can significantly suppress the lateral swing and rotation of the workpiece, avoid the collision between workpieces and positioning deviation caused by the swing, and improve the operational stability and assembly accuracy of the suspension assembly production line.

[0023] A pressure plate 6 is installed on the inner side of the end of the pressure rod 5 away from the positioning seat 3; the pressure rod 5 is rotatably connected to the positioning seat 3 via a first hinge 4; both sides of the pull rod 8 are rotatably connected to the slider 7 via second hinges 9 respectively; the slider 7 is dampedly connected to the pressure rod 5. The pressure plate 6 is installed on the inner side of the end of the pressure rod 5 away from the positioning seat 3, which increases the contact area with the workpiece, can disperse the force during clamping, avoid local indentation on the workpiece, and improve the stability of clamping.

[0024] A locking mechanism is provided between the pull rod 8 and the first rod portion 15. The locking mechanism includes a support rod 12 rotatably connected to the pull rod 8 via a third hinge 14. A friction block 11 is connected to the end of the support rod 12. A first spring 13 is installed between the support rod 12 and the pull rod 8. The first spring 13 can apply a pushing force to the support rod 12 against the first rod portion 15. Two locking mechanisms are symmetrically arranged, and a rope 10 is connected between the support rods 12 of the two locking mechanisms. The pressure rod 5 includes a first rod portion 15, a second spring 16, and a second rod portion 17 connected in sequence. A pressure plate 6 is installed on the inner side of the second rod portion 17.

[0025] A locking mechanism is provided between the pull rod 8 and the first rod portion 15. The locking mechanism includes a support rod 12 rotatably connected to the pull rod 8 via a third hinge 14. A friction block 11 is fixed to the end of the support rod 12. A first spring 13 is installed between the support rod 12 and the pull rod 8. The first spring 13 continuously pushes the support rod 12, causing the friction block 11 to abut against the first rod portion 15, thereby forming a self-locking constraint on the pull rod 8. The two locking mechanisms are symmetrically arranged, and the two support rods 12 are connected by a rope 10. The operator can pull the rope 10 to disengage the support rod 12 from the abutment position, and the pull rod 8 will be unlocked and regain free movement. The pressure rod 5 is composed of the first rod portion 15, the second spring 16, and the second rod portion 17 connected in sequence. A pressure plate 6 is installed on the inner side of the second rod portion 17. The pressure plate 6 is in close contact with and clamps the workpiece surface. The second spring 16 can provide elastic compliance when subjected to force to prevent the workpiece from being subjected to excessive compression. Remote synchronous unlocking can be achieved by pulling the rope 10, making the operation simple and quick. The pressure bar 5 adopts a segmented structure consisting of a first rod 15, a second spring 16, and a second rod 17. This structure ensures clamping strength while providing elastic buffering through the second spring 16 to prevent damage to the workpiece. It also improves the adaptability and reliability of clamping.

[0026] In one implementation, the workpiece is hung on the hook 2. During operation, pulling down the pull rod 8 causes the pull rod 8 to simultaneously drive the sliders 7 on both sides to slide along the pressure rod 5 via the second hinge 9. This causes the two pressure rods 5 to swing inward toward the workpiece around the first hinge 4, and the pressure plate 6 at the end of the pressure rod abuts against the outer side of the workpiece to form a clamp. A damping connection is provided between the slider 7 and the pressure rod 5 to provide viscous damping during clamping and releasing, suppressing secondary oscillations caused by sudden acceleration. The positioning seat 3 is fixedly mounted on the traveling frame rod 1, providing a symmetrical hinge reference for the two pressure rods 5. When long-distance transportation is required, the pull rod 8 is equipped with a locking mechanism consisting of a support rod 12, a friction block 11, a first spring 13, and a third hinge 14. The first spring 13 continuously pushes the support rod 12, causing the friction block 11 to abut against the first rod portion 15, forming a self-locking mechanism on the pull rod 8 to prevent the clamping from loosening. When unlocking is required, the rope 10 can be pulled to disengage the support rod 12 from the clamping position. After the pull rod 8 returns to its original position, the two pressure rods 5 swing outward to release the clamping. In some embodiments, the pressure rod 5 consists of a first rod portion 15, a second spring 16, and a second rod portion 17 connected in series. The second spring 16 provides compliance to absorb impact and prevent excessive compression of the workpiece.

Any technical solution, concept, or design obtained by those skilled in the art by making equivalent substitutions or changes based on the technical solution and utility model concept disclosed in the present utility model should be included within the protection scope of the present utility model.
