Description

Technical Field

[0001] This utility model relates to the technical field of tobacco processing equipment, specifically to a device for disassembling and assembling the rocker arm buffer ring of a vibrating conveyor. Background Technology

[0002] In the vibrating conveyor (also known as a vibrating trough) of the tobacco processing workshop, the rocker arm assembly, as a key structure connecting the trough body and the frame, is responsible for transmitting the excitation force to the trough. Because this assembly is subjected to high-frequency reciprocating loads for a long time during operation, a buffer structure is usually set between the rocker arm and the trough body to reduce vibration impact, reduce structural fatigue, and improve the stability and reliability of the whole machine operation.

[0003] In existing technology, this buffer structure mainly consists of three parts: a buffer ring, an aluminum core support, and a rocker arm body. Specifically, the rocker arm body has a mounting hole at its end, and the inner wall of the mounting hole has a wedge-shaped limiting groove. During installation, the buffer ring is first inserted into the mounting hole, and then a wedge is inserted from the side. The wedge's inclined surface presses the outer periphery of the buffer ring into the wedge-shaped groove, thereby firmly positioning the buffer ring in the hole and achieving initial locking. Subsequently, the aluminum core support is embedded into the central hole of the buffer ring, completing the assembly of the entire buffer assembly. This structure can effectively absorb some vibration energy and ensure the stability of the assembly under long-term vibration environment through wedge fixing.

[0004] However, under prolonged high-frequency vibration conditions, the buffer ring is prone to plastic deformation, localized tearing, or loosening of the fit with the aluminum core support, leading to degradation of buffering performance, decreased vibration transmission efficiency, and in severe cases, even component detachment, abnormal amplitude, and other malfunctions, affecting the normal operation of the equipment. Therefore, the buffer ring needs to be maintained and replaced regularly.

[0005] Current replacement procedures typically involve two steps: removal of the old part and installation of the new part.

[0006] When disassembling old components, to prevent the rocker arm from swaying during disassembly, existing technology typically uses a manually rotated screw to drive a clamping block to tighten and fix the rocker arm. This method is inefficient, labor-intensive, and the clamping force is difficult to control precisely. On the one hand, insufficient clamping force may cause the buffer component to be loosely fixed, increasing the difficulty of disassembly and affecting the reliability of equipment operation; on the other hand, excessive clamping force may damage the rocker arm structure and shorten the service life of the equipment.

[0007] During the installation of new components, operators must manually align the aluminum core support with the mounting hole on the rocker arm body, and then use a cylinder to press the aluminum core support into the buffer ring. This installation method requires high positioning accuracy from the operator and poses significant safety hazards due to limited operating space. Especially at the moment the cylinder is activated, if the operator does not remove their hands in time, a pinching injury is highly likely. Furthermore, manual positioning may result in poor fit between the aluminum core support and the mounting hole, leading to equipment malfunctions and affecting the stable operation and maintenance efficiency of the equipment.

[0008] This application is submitted to address the above issues. Utility Model Content

[0018] The bottom wall of the connecting block 20 is connected to the clamp 23 on both sides by connecting rods 22. The clamp 23 is used to clamp the part to be processed in cooperation with the support plate 3 to achieve its positioning or fixing operation.

[0019] The inner wall between the support base 15 and the support plate 3 is provided with a stabilizing mechanism, which is used to limit and guide the movement of the clamp 23 to prevent displacement during disassembly and assembly, thereby improving the accuracy and stability of the disassembly and assembly process.

[0023] To ensure the smooth rotation of the lead screw in the rocker arm buffer ring disassembly and assembly device of the vibrating conveyor, the motor 16 is fixedly mounted on the support base 15.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. This utility model uses a motor to drive the lead screw to rotate, which in turn moves related components to press the rocker arm. Compared with the traditional hand-cranked lead screw method, it greatly shortens the operation time, reduces the physical exertion of workers, and significantly improves the overall work efficiency of buffer ring disassembly and assembly. When installing the aluminum core support, the specific structural design makes the installation process more convenient and efficient, effectively reducing equipment maintenance and downtime, which is conducive to the continuity and efficiency of enterprise production.

[0028] 2. With the help of the motor-driven lead screw and related connection structure design, the clamping force on the rocker arm can be controlled more precisely, avoiding problems such as loose installation of the buffer ring or damage to the rocker arm caused by the difficulty in accurately controlling the clamping force by hand. This effectively ensures the stability and service life of the equipment and improves the quality of equipment maintenance.

[0029] 3. During the installation and disassembly of the aluminum core support, workers do not need to manually operate the alignment and pressing of the aluminum core support with the mounting hole. Instead, the relevant components are driven by a cylinder to complete the process. This effectively avoids the safety risks caused by workers' hands being near the moving area of ​​the equipment, reduces the possibility of accidents such as workers being pinched, protects the personal safety of workers, and is conducive to the company's safe production management.

[0030] 4. The structural design of this utility model, such as the fixing and positioning function of the pressure plate and slide for the aluminum core support, enables the aluminum core support to more accurately match the rocker arm mounting hole during installation, reducing the potential equipment failure caused by poor manual alignment, further improving the reliability and stability of equipment operation, and reducing equipment maintenance costs.

Detailed Implementation

[0038] See Figure 1-4 As shown, a device for disassembling and assembling a rocker arm buffer ring of a vibrating conveyor includes a base plate 1. Support columns 2 are provided on both the left and right sides of the top wall of the base plate 1. A support plate 3 is provided at the bottom of the inner side wall between the support columns 2. The bottom of the rear side wall of the support plate 3 is fixedly connected to the top wall of the base plate 1 through a support block 4. A baffle 5 is provided at the top of the inner side wall between the support columns 2. A fixing mechanism is provided on the rear side wall of the baffle 5.

Hollow connecting cylinders 9 are interference-fitted to the inner walls of the left and right sides of the connecting plate 7. A hollow pressure plate 10 is provided on the bottom end wall of the connecting cylinder 9. Two sets of supporting mechanisms are provided on the top wall of the base plate 1 between the support columns 2.

[0039] Furthermore, the fixing mechanism includes a support base 15, a motor 16 is provided on the outer wall of the support base 15, and a lead screw 19 is locked to the output end of the motor 16 through a coupling. A connecting block 20 is threadedly connected to the outer wall of the lead screw 19. Clamps 23 are provided on both sides of the bottom wall of the connecting block 20 through connecting rods 22. A stabilizing mechanism is provided on the inner wall between the support base 15 and the support plate 3. The motor 16 causes the lead screw 19 to rotate, and the lead screw 19 causes the connecting block 20 to drive the slider 21, connecting rods 22 and slide block 13 to move downward. The clamps 23 press and fix the rocker arm on the support plate 3.

[0040] Furthermore, the stabilizing mechanism includes a column 17, and a groove 18 is provided on the front side wall of the column 17. A slider 21 is slidably connected in the groove 18, and the front side wall of the slider 21 is fixedly connected to the outer wall of the connecting block 20. The slider 21 moves up and down in the groove 18 to limit and stabilize the connecting block 20, preventing the connecting block 20 from rotating with the moving screw 19.

[0041] Furthermore, the outer wall of the lead screw 19 is rotatably connected to the outer wall of the support base 15 through a bearing, and the bearing fixes the lead screw 19, making it convenient for the lead screw 19 to rotate through the bearing.

[0042] Furthermore, the supporting mechanism includes a base 11, a slide rod 12 on the top wall of the base 11, a slide seat 13 movably connected to the outer wall of the slide rod 12, and a spring 14 movably sleeved on the outer wall of the slide rod 12. The upper and lower ends of the spring 14 are fixedly connected to the outer walls of the base 11 and the slide seat 13, respectively. The aluminum core support is placed on the two slide seats 13. The cylinder 6 drives the connecting plate 7 and pushes the top rod 8, connecting cylinder 9 and pressure plate 10 downward. The two pressure plates 10 press on the outer walls on both sides of the aluminum core support. The pressure plates 10 and the slide seats 13 fix the aluminum core support. At the same time, the top rod 8 contacts the middle of the top wall of the aluminum core support and pushes the aluminum core support downward, pressing it into the rocker arm mounting hole.

[0043] Furthermore, the top wall of the slide rod 12 extends into the connecting cylinder 9, so that when the cylinder 6 is started, the connecting plate 7 can drive the push rod 8, the connecting cylinder 9 and the pressure plate 10 to move up and down on the outer wall of the slide rod 12.

[0044] As a preferred embodiment, the support plate (3) is provided with a through hole at the position corresponding to the top rod (8). The through hole is used to allow the top rod (8) and the aluminum core support to pass through in the vertical direction, and also to provide the necessary reaction force support for the top rod (8) to push the aluminum core support downward, so as to ensure that the pushing process is stable and reliable.

[0045] For those skilled in the art, all electrical components and parts in this case are general standard parts or parts known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods. All models are compatible with this solution and can operate normally. All electrical components in this case are connected to their compatible power supplies through wires. According to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence should refer to the working principle below, and the electrical connection is completed by the sequential operation of each electrical component. The detailed connection method is a well-known technology in the art, and the electrical control will not be described further.

[0046] One specific application of this embodiment is:

[0047] In use, the rocker arm of the vibratory conveyor is placed on the support plate 3, with the mounting hole positioned below the top rod 8. The motor 16 drives the lead screw 19 to rotate, which in turn drives the connecting block 20 to move the slider 21, connecting rod 22, and slide block 13 downwards. The clamp 23 presses and fixes the rocker arm body onto the support plate 3. The cylinder 6 drives the connecting plate 7 and pushes the top rod 8, connecting cylinder 9, and pressure plate 10 downwards. The pressure plate 10 moves downwards and contacts the slide block 13, pushing the slide block 13 downwards to compress the spring 14. At the same time, the top rod 8 moves downwards and contacts the aluminum core support in the rocker arm mounting hole, pushing the aluminum core support downwards out of the mounting hole. Then, the wedge is removed, completing the disassembly of the buffer ring and the aluminum core support. The cylinder 6 drives the connecting plate 7 and pushes the top rod 8, connecting cylinder 9, and pressure plate 10 upwards to reset. The spring 14 pushes the slide block 13 upwards to reset.

[0048] During installation, when installing the buffer ring, first insert the buffer ring and wedge into the mounting hole of the rocker arm in sequence, and then temporarily set up the aluminum core support on the two slide blocks 13. The bottom end of the aluminum core support is located above the wedge in the mounting hole. At this time, the pressure plates 10 at the bottom of the two connecting cylinders 9 contact the outer walls on both sides of the aluminum core support, and cooperate with the slide blocks 13 to provide lateral limiting and attitude stabilization support for the aluminum core support. Subsequently, the connecting plate 7 is driven by the cylinder 6, which in turn drives the push rod 8, connecting cylinder 9 and pressure plate 10 to move downward as a whole. While the pressure plate maintains its lateral limiting function, the push rod 8 contacts the middle of the top wall of the aluminum core support and applies downward pressure, pushing the aluminum core support from the slide position into the mounting hole of the rocker arm to complete the installation. The installation of the buffer ring and the aluminum core support is completed. The connecting plate 7, push rod 8, connecting cylinder 9 and pressure plate 10 are driven by the cylinder 6 to move upward and reset. The motor 16 is reversed and started, causing the connecting block 20 to drive the slider 21, connecting rod 22 and clamp 23 to move upward and reset, detaching from the rocker arm body and removing the rocker arm body.

[0049] It should be noted that during the process, the pressure plate and slide are mainly used to stabilize and limit the installation posture of the aluminum core support, and do not hinder the downward pressing installation action of the top rod. Preferably, the pressure plate can partially cover and abut against the upper outer walls on both sides of the aluminum core support to achieve lateral limiting and support of the aluminum core support; the upper surface of the slide 13 is provided with a limiting groove or positioning protrusion to support the aluminum core support and prevent its lateral displacement and posture deviation, thereby ensuring that the aluminum core support maintains a stable positioning state before the top rod is pressed down.

[0050] Of course, the above description is not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, alterations, additions or substitutions made by those skilled in the art within the scope of the present utility model should be protected by the present utility model.
