Description

Technical Field

[0001] This utility model relates to the field of frame pressing machine flipping technology, and more specifically, it relates to a special assembly flipping mechanism for frame pressing machines. Background Technology

[0002] The specialized assembly and tilting mechanism of the frame pressing machine is a key component in the assembly process. It is primarily used to achieve angle changes in the frame material during the pressing operation, ensuring the frame is in the appropriate posture at different workstations and in different processes to meet the multi-directional and multi-angle processing requirements of the frame pressing process. By precisely controlling the tilting of the frame, this mechanism can improve the efficiency and quality of the pressing process, ensuring its smooth operation.

[0003] Currently, during frame pressing operations, due to process requirements, the frame material often needs to be pressed multiple times at different angles. In this process, the angle reversal of the frame material becomes an essential step. However, traditional reversal methods mostly rely on manual operation, requiring operators to expend a lot of physical strength to repeatedly move the frame material. This is not only labor-intensive and inefficient, but also poses safety hazards due to frequent manual handling, which may lead to accidents such as operator injuries. It is difficult to meet the needs of modern industrial production for high efficiency, precision, and safety. Utility Model Content

[0024] Please see Figures 1-4The system includes a conveyor belt support, characterized in that: a drive motor is fixedly connected to the outer surface of the conveyor belt support; a gearbox is fixedly connected to the output end of the drive motor; a first rotating shaft is rotatably connected to the outer surface of the conveyor belt support; the output end of the drive motor is fixedly connected to the input end of the gearbox; the output end of the gearbox is fixedly connected to one end of the first rotating shaft; a double-row sprocket is fixedly connected to the outer surface of the first rotating shaft; several double-row sprockets are arranged in a rectangular array and evenly distributed; the outer surfaces of the several double-row sprockets are connected by a second chain drive; one end of an active conveyor roller passes through the front of the conveyor belt support; a single-row gear is fixedly connected to one end of the active conveyor roller; the outer surface of the single-row gear is connected to the outer surface of the double-row sprockets via a first chain drive; several active conveyor rollers are arranged in a rectangular array and evenly distributed; an active conveyor roller is rotatably connected to the inner wall of the conveyor belt support; a lifting plate is rotatably connected to the outer surface of the conveyor belt support via a connecting plate and a second rotating shaft; and the inner wall of the lifting plate is rotatably connected to... The conveyor belt support is equipped with several driven conveyor rollers arranged in a rectangular array. These driven rollers are interspersed with the driving conveyor rollers. One end of the lifting plate is hinged to a limit plate via a second rotating shaft. The inner wall of the limit plate is rotatably connected to several driven conveyor rollers arranged in a rectangular array. These driven rollers are interspersed with the driving conveyor rollers. The inner wall of the lifting plate is rotatably connected to a first hydraulic cylinder. One end of the telescopic rod of the first hydraulic cylinder is rotatably connected to the inner wall of the limit plate. One end of the telescopic rod of the second hydraulic cylinder is rotatably connected to the outer surface of the lifting plate. A hydraulic pump and a flow divider are provided on the lower surface of the conveyor belt support. The hydraulic pump, flow divider, first hydraulic cylinder, and second hydraulic cylinder are all connected through conduits. The outer surface of the conveyor belt support is rotatably connected to a second hydraulic cylinder. Limit switches are fixedly connected to the inner walls of the first driven conveyor rollers and the inner walls of the limit plate. Buffer pads are fixedly connected to the upper surfaces of both ends of the conveyor belt support.

[0025] Specifically, the lifting plate is rotatably connected to the conveyor belt support via a second rotating shaft. Several first driven conveying rollers on its inner wall are interleaved with the driving conveying rollers to clamp the frame material. A limiting plate is hinged to one end of the lifting plate via the second rotating shaft. Several second driven conveying rollers on its inner wall are also interleaved with the driving conveying rollers to define the flipping path. One end of the first hydraulic cylinder telescopic rod is rotatably connected to the inner wall of the limiting plate, and the other end is driven by the hydraulic system to rotate the limiting plate. One end of the second hydraulic cylinder telescopic rod is rotatably connected to the outer surface of the lifting plate to drive the entire lifting plate to flip. The output end of the drive motor is fixedly connected to the gearbox, which drives the double-row chain via the first rotating shaft. As the wheel rotates, several double-row sprockets are driven by a second chain. A single-row gear at one end of the active conveying roller is driven by the first chain and the double-row sprockets to make multiple active conveying rollers rotate synchronously. The hydraulic pump and the distributor are connected to the first and second hydraulic cylinders through conduits to independently control their extension and retraction. The active and driven conveying rollers are distributed in a cross pattern so that the frame material is in a multi-roller clamping state during conveying. When it is necessary to flip, the hydraulic system drives the lifting plate and the limiting plate to move. The driven conveying roller adjusts its direction with the flip, so that the frame material can be automatically flipped synchronously during conveying, avoiding manual intervention, improving efficiency and accuracy. The transmission system ensures stable conveying of the frame and provides a basis for flipping.

[0026] In summary, when using the entire equipment: the right end of the device is connected before the next frame pressing process, and the left end is positioned in front of the frame pressing machine. During operation, the drive motor provides power, which is transmitted to the first rotating shaft after being changed through the gearbox. The power is then transmitted to the active conveyor roller through the double-row sprockets, the first chain, and the single-row gear, causing the active conveyor roller to rotate. The coordinated arrangement of multiple first rotating shafts, double-row sprockets, and second chains can drive multiple active conveyor rollers to rotate synchronously, transporting the frame from right to left. When reversal is required, the limit switch is pressed, and the time to reach the hinge point between the lifting plate and the limit plate is calculated based on the conveying speed of the active conveyor roller. Subsequently, the first... When the extension rod of the hydraulic cylinder retracts, it lifts the left end of the limit plate, making the limit plate perpendicular to the lifting plate. After a specified time, the extension rod of the second hydraulic cylinder extends, lifting the right end of the lifting plate. At this time, several first driven conveyor rollers lift the right end of the frame upwards, and the weight of the frame causes the left side of the frame to press tightly against the outer surface of the second driven conveyor rollers until the limit plate falls back to its original position, thus completing the frame reversal effect. Subsequently, as the extension rod of the second hydraulic cylinder retracts, the extension rod of the first hydraulic cylinder extends, making the lifting plate and the limit plate at a flat angle. This allows the frame to be flipped when needed, or used as a regular conveyor belt when flipping is not required.
