Description
Technical Field
[0001] This utility model relates to the field of high-speed cylinder installation technology, and in particular to a high-speed cylinder installation device. Background Technology
[0002] In today's industrial production, high-speed feeding devices are widely used in various stamping production lines, especially in industries such as automobile manufacturing, where their importance is increasingly prominent. With the continuous advancement of materials science, new materials such as high-strength aluminum-magnesium alloys are gradually being applied to the production of automotive exterior body panels. This change places more stringent demands on the production cycle time of material handling devices, prompting a continuous increase in the operating cycle time of high-speed feeding devices. Simultaneously, with the development of control technology and the continuous development of specialized material handling equipment, the operating cycle time of high-speed feeding devices has been gradually improved.
[0003] Currently, high-speed feeding devices in large stamping production lines purchased by mainstream automotive OEMs are generally equipped with balancing cylinders to counteract the gravity of the moving parts of the feeding device and improve the high responsiveness of the equipment. Among these, long-stroke cylinders are mostly made of aluminum alloy. However, due to the low elastic modulus of aluminum, when the upper end cap, lower end cap, and cylinder body are connected as a whole by tension bolts, the connection is easily affected by a combination of factors, including the tension bolt preload sequence, the magnitude of the preload force, and the machining accuracy of the cylinder body itself. This often results in difficulty in ensuring the perpendicularity of the cylinder mounting surface to the cylinder body. After installation, the piston rod may be tilted relative to the cylinder body, further exacerbating uneven wear.
[0004] Furthermore, cylinder mounting brackets are typically large in size, with common dimensions reaching 1000 * 3000 mm. This places extremely high demands on the precision and performance of the machine tools used for machining. If the cylinder mounting surface and guide surface cannot be machined with high precision in a single operation, it becomes extremely difficult to ensure parallelism between the two surfaces, which further exacerbates the problem of uneven wear. Considering the characteristics of high-speed feeding devices, such as high cycle time requirements (≥15 SPM), extremely frequent cylinder operations (≥60 SPM), and large vertical shaft lifting stroke (≥1000 mm), the cylinders of high-speed feeding devices frequently experience serious problems such as uneven piston rod wear (unilateral scoring), guide sleeve wear, and sealing device failure before reaching their design life. These problems not only severely affect the reliable and stable production of the equipment and significantly increase the workload and cost of equipment maintenance, but also greatly hinder the entire production process, having a very negative impact on production efficiency and economic benefits. Utility Model Content
[0005] To address the problems of uneven piston rod wear (unilateral scoring), guide sleeve wear, and sealing device failure during the installation of high-speed cylinders, this utility model provides a high-speed cylinder installation device.
[0006] To solve the above problems, the technical solution adopted by this utility model is as follows:
[0007] A high-speed cylinder mounting device includes a trunnion assembly mounted on the piston rod of the cylinder, and a support assembly mounted on the end of the cylinder body. The support assembly includes a bolt; the bolt is threadedly connected to the cylinder body; and the end of the bolt away from the cylinder is movably connected to the mounting assembly. This high-speed cylinder mounting device, by setting a support assembly at the end of the cylinder body, utilizing the threaded connection between the bolt and the cylinder body, and the movable connection between the end of the bolt away from the cylinder and the mounting assembly, combined with the trunnion assembly on the piston rod, provides flexible installation and adjustment space at both ends of the cylinder. This effectively alleviates the problem of piston rod and cylinder body tilting caused by insufficient perpendicularity between the cylinder mounting surface and the cylinder body, or insufficient machining accuracy of the mounting bracket. It also reduces piston rod wear, guide sleeve wear, and sealing device failure, improving the reliability and service life of the cylinder during high-frequency, long-stroke operation of the high-speed feeding device, reducing equipment maintenance costs, and ensuring the stable and efficient operation of the high-speed feeding device.
[0008] Preferably, the mounting assembly includes a circular tube; a disc is fixedly mounted on the lower outer wall of the circular tube; a conical surface is provided at the top edge of the inner diameter of the circular tube; a bolt passes through the circular tube and is threadedly connected to the connecting assembly; the connecting assembly connects to the cylinder body. The circular tube of the mounting assembly provides space for the bolt to pass through and install. The disc on its lower outer wall facilitates a stable connection with the external structure, while the conical surface at the top edge of the inner diameter of the circular tube provides an appropriate angle buffer for the movement of the bolt. Combined with the structure where the bolt passes through the circular tube and is threadedly connected to the connecting assembly connecting the cylinder body, a reliable connection between the support assembly and the cylinder body is achieved. Furthermore, the cooperation between the conical surface and the bolt enhances the flexibility of the bolt's movement, further improving the angle adjustment capability during cylinder installation. This effectively reduces radial force caused by installation deviations, thereby mitigating problems such as piston rod wear and guide sleeve wear, extending the cylinder's service life, and ensuring stable equipment operation.
[0009] Preferably, a tapered bearing is mounted on bolt one; the tapered bearing is positioned between the tail end of bolt one and the mounting assembly; a clearance groove is formed on the bottom surface of the mounting assembly to accommodate the tapered bearing. The tapered bearing mounted on bolt one is located between its tail end and the mounting assembly, and the clearance groove on the bottom surface of the mounting assembly provides suitable installation space for the tapered bearing. The special structure of the tapered bearing can further enhance the flexibility of angle adjustment between bolt one and the mounting assembly. Through tapered contact, the stress at the connection point is effectively dispersed, reducing the impact of radial forces generated during installation deviation or cylinder operation on bolt one and the mounting assembly. At the same time, the clearance groove ensures that the movement of the tapered bearing is not interfered with, allowing the cylinder to more smoothly self-adapt and fine-tune during high-frequency, long-stroke movements. This further alleviates the tilting problem between the piston rod and the cylinder body, reduces the risk of piston rod wear, guide sleeve wear, and sealing device failure, and significantly improves the overall stability and service life of the device.
[0010] Preferably, bolt one is clearance-fitted with the inner wall of the round tube one. This clearance fit provides a certain amount of room for movement within the round tube one, allowing for small adjustments in the radial direction. This effectively compensates for minor displacements caused by machining errors, assembly deviations, or cylinder operation, and avoids additional stress caused by rigid contact between the bolt one and the round tube one. This fit, combined with other flexible adjustment structures in the support assembly, further enhances the overall adaptability of the cylinder installation, reduces the tilting stress between the piston rod and the cylinder body, thereby mitigating problems such as piston rod wear and guide sleeve wear. This ensures stable cylinder operation under high-frequency, long-stroke conditions and extends the equipment's service life.
[0011] Preferably, the disc has a plurality of through holes evenly distributed along its circumference. These through holes provide convenient and diverse connection points for fixing the mounting components to the connecting plate. The evenly distributed through hole design ensures balanced force distribution during connection, preventing loosening or deformation caused by localized stress concentration. Furthermore, suitable through holes can be flexibly selected for fixing according to actual installation requirements, improving the flexibility of installation and adjustment. This structure, combined with other adjustment functions of the support components, further enhances the stability and adaptability of the cylinder installation, reducing the adverse effects of vibration or misalignment caused by unstable connections on cylinder operation, thereby helping to alleviate problems such as piston rod wear and ensuring long-term reliable operation of the equipment.
[0012] Preferably, the connecting assembly includes a second circular tube; a second disc is fixedly mounted on the lower outer wall of the second circular tube; the inner wall of the second circular tube is threaded, and a bolt is threaded inside the second circular tube; several through holes are evenly distributed along the circumference of the second disc; the second disc is threaded onto the cylinder body by the bolt passing through the through holes. The second circular tube of the connecting assembly is stably connected to the bolt through the inner wall thread, providing a reliable force support point for the supporting assembly; the second disc on the lower outer wall, with its evenly distributed through holes, works with the bolt to form a multi-point fixation with the cylinder body, effectively dispersing the stress at the connection points and avoiding connection failure caused by excessive local stress. This structure ensures the firmness of the connection between the supporting assembly and the cylinder body, and also provides space for angle adjustment through the threaded engagement of the second circular tube and the bolt. Combined with the multi-point fixation of the second disc, it further improves the stability and adjustment flexibility of the cylinder installation, reduces problems such as piston rod wear and guide sleeve wear caused by loose connections or uneven stress, and extends the service life of the cylinder.
[0013] Preferably, a nut is threaded onto the bolt; the nut abuts against the bottom surface of the connecting component. Tightening the nut secures the connection between the bolt and the connecting component, effectively preventing loosening due to vibration during high-frequency, long-stroke cylinder movements, thus ensuring the stability of the support component structure. Furthermore, this locking method allows adjustment of the bolt's extension length according to actual installation requirements, further optimizing the stress state of the support component in conjunction with the connection between the connecting component and the cylinder body. This reduces cylinder installation misalignment caused by loose connections, thereby mitigating piston rod wear, guide sleeve wear, and other problems, ensuring reliable operation of the device.
[0014] Preferably, a connecting plate is connected to the disc one via bolt three passing through the through hole one; the connecting plate is installed on the top surface of the disc one. The disc one is connected to the connecting plate via bolt three passing through the through hole one, and the connecting plate is installed on the top surface of the disc one. This connection method not only achieves a stable connection between the support component and the external installation structure, but the evenly distributed through holes one, combined with bolt three, also ensures balanced force distribution, avoiding deformation or loosening of the connection points caused by localized stress concentration. Simultaneously, the connecting plate increases the contact area between the support component and the external structure, further improving installation stability. This allows the cylinder to maintain a stable installation posture during high-frequency, long-stroke movements, reducing interference from vibrations or misalignments caused by unstable installation, thereby helping to alleviate problems such as piston rod wear and ensuring long-term efficient operation of the equipment.
[0015] Preferably, the trunnion assembly includes a connecting rod; the piston rod of the cylinder is threaded onto the connecting rod; a trunnion pair is rotatably mounted on the end of the connecting rod away from the piston rod; and a trunnion is fixedly mounted inside the trunnion pair. In the trunnion assembly, the threaded connection between the cylinder piston rod and the connecting rod facilitates installation and position adjustment. The end of the connecting rod away from the piston rod is connected to the trunnion via the rotatably mounted trunnion pair, allowing the trunnion to rotate flexibly relative to the connecting rod, providing the cylinder piston rod end with multiple degrees of freedom for axial and radial adjustment. This structure effectively counteracts additional torque generated due to installation errors or during movement, avoids unnecessary radial force on the piston rod, and works in conjunction with the support assembly to further reduce piston rod wear, guide sleeve wear, and other phenomena, improving the stability of the cylinder during high-frequency movement and extending its service life.
[0016] Preferably, a second nut is threaded onto the connecting rod; the second nut abuts against the bottom surface of the connecting rod. Tightening the second nut locks the threaded connection between the cylinder piston rod and the connecting rod, effectively preventing relative loosening of the piston rod and connecting rod due to vibration during high-frequency reciprocating motion of the cylinder, thus ensuring the stability of the connection between the trunnion assembly and the piston rod. Simultaneously, the second nut also helps adjust the assembly depth of the piston rod within the connecting rod, optimizing the force distribution of the trunnion assembly. Combined with the rotational characteristics of the trunnion pair, this further improves the motion coordination of the cylinder piston rod end, reducing piston rod force offset caused by loose connection, thereby mitigating uneven wear and ensuring the reliable operation of the trunnion assembly and the entire cylinder mounting device.
[0017] As can be seen from the above technical solutions, the advantages of this utility model include: the external pipe sealing device quickly tightens the chain through a ratchet chain tightening mechanism, so that the adaptive limiting mechanism fits tightly against the outer wall of the pipe, effectively solving the problem that traditional rigid clamps have high requirements for the flatness of the pipe surface and are difficult to adapt to complex-shaped pipes; the limiting effect of the adaptive limiting mechanism on the expansion component, together with the expansion component and the sealing plate, realizes multi-level sealing. When micro-leakage occurs, the expansion component can further enhance the sealing effect, avoiding the drawback of repeated disassembly and adjustment required for single-level sealing, improving the emergency handling efficiency of large-diameter or high-pressure pipe leaks, reducing economic losses and safety risks, and providing an efficient and reliable solution for emergency repair of pipe leaks.
