Description

Technical Field

[0001] The utility model relates to the technical field of mechanical connection, in particular to a quick coupling mechanism. Background Art

[0002] A leveler is a piece of equipment used for sheet metal processing. Its primary function is to mechanically straighten sheet metal to achieve the desired flatness and geometric shape. Traditionally, levelers have used couplings that are fixed one to another. Because there are 19 or as many as 23 couplings, each disassembly takes a long time, resulting in extremely low efficiency and posing safety risks to workers.

[0003] Currently, the industry widely employs various technical methods to quickly connect multiple couplings. For example, threaded connections secure multiple couplings together by screwing nuts together. Another method utilizes pins or clips, which can be inserted or removed to quickly connect couplings. While these methods improve coupling connection speed to a certain extent, they still have limitations. Utility Model Content

[0009] By adopting the above technical solution, the buffer spring can effectively reduce the impact force between the drive shaft and the internal spline sleeve during use, improving the smoothness and reliability of the equipment's operation and extending its service life. Specifically, the buffer spring can absorb some of the vibration and impact energy during the transmission process, thereby reducing the vibration amplitude of the transmission system, minimizing mechanical wear, and ensuring stable system operation.

[0013] By adopting the above technical solution, when in use, the positioning protrusion on the inner spline sleeve matches the positioning groove on the outer spline sleeve, ensuring that the two can be aligned quickly and accurately when docking, improving the accuracy and efficiency of the coupling docking, and reducing mechanical failures caused by misalignment.

[0014] Preferably, the ends of the inner spline sleeve and the outer spline sleeve are both provided with connecting holes, and the connecting holes are used to respectively cooperate and connect the transmission shaft and the coupling.

[0015] By adopting the above technical solution, when in use, the ends of the inner spline sleeve and the outer spline sleeve are provided with connecting holes, which can ensure the precise connection between them and the transmission shaft and the coupling, thereby improving the stability and reliability of the coupling.

[0016] Preferably, the coupling frame is provided with a plurality of fixing holes, the fixing holes are for the external spline sleeve to pass through, and the fixing holes are used to set fixing pieces to help fix the external spline sleeve so that it does not fall off.

[0017] By adopting the above technical solution, when in use, the fixing hole on the coupling frame can effectively fix the external spline sleeve to prevent it from falling off during use, thereby improving the overall stability and reliability of the coupling quick docking mechanism.

[0018] Preferably, a lubricating layer is applied on the surface of the external spline sleeve.

[0019] By adopting the above technical solution, when in use, the surface of the outer spline shaft sleeve is provided with a lubricating layer, which can effectively reduce the friction between the outer spline shaft sleeve and the inner spline shaft sleeve and improve the transmission efficiency.

[0020] Preferably, a connecting frame is provided on one side of the coupling frame, and the connecting frame is used to connect a driving device that drives the coupling to move.

[0021] By adopting the above technical solution, when in use, the setting of the connecting frame enables the driving device to be effectively connected to the coupling frame, thereby achieving precise control and movement of the coupling, and improving the docking efficiency and accuracy of the coupling.

[0022] In summary, this application has the following beneficial effects:

[0023] 1. This utility model designs a quick-connection mechanism for a coupling. The key teeth on the external spline sleeve and the key slots on the internal spline sleeve cooperate with each other to achieve rapid and precise connection between the coupling and the drive shaft. This not only enables the rapid connection of multiple couplings, but also significantly improves connection efficiency and accuracy.
