Description

Technical Field

[0001] This utility model relates to the field of ultra-large hydraulic cylinder assembly technology, and in particular to a cylinder operating platform for assembling large hydraulic cylinders. Background Technology

[0002] In the fields of heavy machinery, engineering equipment, and hydraulics, ultra-large hydraulic cylinders are core actuators, and their assembly quality directly affects the working performance and reliability of the entire equipment. The cylinder barrel and piston rod assemblies of such cylinders are usually characterized by their large size and heavy weight, and their assembly process is far beyond human capability, requiring specialized tooling equipment to complete.

[0003] During assembly, when it is necessary to adjust the circumferential angle of the cylinder to ensure accurate alignment of internal oil passages, buffer structures, etc., operators usually need to use tools such as pry bars to laboriously pry or rotate the heavy cylinder manually. The adjustment process is not only extremely labor-intensive and inefficient, but also poses serious safety hazards.

[0004] Relying entirely on manual prying to rotate the massive cylinder makes precise fine-tuning difficult. The internal oil ports of the cylinder and the corresponding structures on the piston assembly are difficult to align quickly and accurately. Misalignment during assembly can easily scratch delicate seals or chrome plating, leading to cylinder leaks from the factory and causing major quality incidents.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the general background of this disclosure and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Detailed Implementation

[0020] 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.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] This application provides a cylinder operating platform for assembling large hydraulic cylinders, which aims to solve the problems of difficulty in adjusting the cylinder angle, poor controllability of the docking process, and low degree of automation in the prior art when assembling large hydraulic cylinders.

[0023] like Figures 1 to 5 As shown, it includes a base 1 and a support assembly 2 and a rotary drive assembly 3 slidably mounted thereon; a first guide rail 11 and a first drive assembly 12 are provided on the base 1, and both the support assembly 2 and the rotary drive assembly 3 are slidably connected to the first guide rail 11. The rotary drive assembly 3 is driven to move through the first drive assembly 12; the support assembly 2 includes a first slide 21 and a lifting bracket 22 mounted thereon, the first slide 21 is slidably connected to the first guide rail 11, and a limit structure 23 is provided on the lifting bracket 22; the rotary drive assembly 3 includes a second slide 31 and a turntable 32 mounted thereon, a clamping assembly 33 is provided on the turntable 32, and the second slide 31 is slidably connected to the first guide rail 11.

[0024] In the specific implementation process, the tail end of the cylinder 4 is clamped and fixed by the clamping assembly 33. The turntable 32 drives the clamping assembly 33 and causes the cylinder 4 to rotate. The first drive assembly 12 pushes or pulls the clamped cylinder 4 for precise linear feed. Although the support assembly 2 is not directly connected to the drive assembly, it is synchronously driven by the cylinder 4 supported on it and slides along the first guide rail 11, ensuring that the cylinder 4 is always stably supported during movement.

[0025] The first drive assembly 12 includes a first motor 121 and a first lead screw 122. The first lead screw 122 is arranged parallel to the first guide rail 11 and is driven to rotate by the first motor 121. The first lead screw 122 is screwed to the second slide block 31. The rotation of the first lead screw 122 provides a smooth, precise, and self-locking linear displacement for the first slide block 21. It is crucial to control the slow and precise docking of the large cylinder and piston rod to avoid damage to the seals caused by excessive speed or loss of control.

[0026] In this embodiment, the lifting bracket 22 includes a worm gear screw jack 221 and a lifting seat 222 disposed thereon. The worm gear screw jack 221 is powered by a third motor 223 and drives the lifting seat 222 to move in the vertical direction.

[0027] The lifting seat 222, together with its upper limit structure 23, provides limiting support for the cylinder body. Driven by the worm gear screw jack 221, it can adapt to cylinders of different diameters. By adjusting the support height, it ensures that the axis of various cylinders can be aligned with the rotation center of the rotary drive assembly 3, greatly improving the versatility of the equipment.

[0028] Two worm gear screw jacks 221 are arranged side by side, and the two worm gear screw jacks 221 are connected in parallel. Two guide rods 211 are vertically arranged on the first slide 21. The top end of the guide rod 211 is fixedly connected to the lifting seat 222, and the guide rod 211 is slidably connected to the first slide 21. The guide rods 211 provide additional guidance and anti-overturning moment for the lifting seat 222, making it run more smoothly when carrying heavy cylinders, and also extending the service life of the worm gear screw jack 221.

[0029] Two worm gear screw jacks 221 are connected in parallel via a linkage shaft and driven by the same third motor 223. This ensures that both sides of the lifting platform 222 rise and fall synchronously, avoiding jamming or tilting of the lifting platform 222 due to asynchrony during the lifting process, and guaranteeing the stability of the support.

[0030] A limiting structure 23 is provided at the top of the lifting bracket 22 to support and limit the main body of the cylinder. The limiting structure 23 includes two horizontally arranged support rollers 231, which are rotatably connected to the lifting seat 222, and their rotation axis is parallel to the first guide rail 11. By replacing the traditional V-block with the support rollers 231, when the cylinder needs to rotate around its axis, the support rollers 231 can rotate with low resistance, thus providing load-bearing and limiting without affecting the cylinder's angle adjustment, making the rotation drive more efficient and precise.

[0031] In this embodiment, the rotation axis of the turntable 32 is arranged parallel to the first guide rail 11, and the clamping component 33 is arranged on the side of the turntable 32 facing the support component 2, which facilitates clamping the cylinder end placed on the support component 2.

[0032] The clamping assembly 33 includes a mounting base 331 and a second drive assembly 34, a second guide rail 332, and a clamping plate 333 disposed thereon. The clamping plate 333 is slidably connected to the second guide rail 332 and is driven to move by the second drive assembly 34. The second guide rail 332 is perpendicular to the first guide rail 11. Two clamping plates 333 are disposed opposite each other on the second guide rail 332. The two clamping plates 333 are driven to move relative to each other by the second drive assembly 34 to achieve clamping or loosening of the tail end connection of cylinders of different specifications.

[0033] Furthermore, the second drive assembly 34 includes a second lead screw 341 and a second motor 342. The second lead screw 341 is arranged parallel to the second guide rail 332 and is driven to rotate by the second motor 342. The second lead screw 341 is screwed to the clamping plate 333.

[0034] The second lead screw 341 is designed as a bidirectional lead screw with one section of left-hand thread and one section of right-hand thread, thus being screwed to the two clamping plates 333 respectively. When the second lead screw 341 rotates, it can drive the two clamping plates 333 to perform precise synchronous relative motion.

[0035] A limiting block 334 is provided on the side of the mounting base 331 facing the support assembly 2, and the limiting block 334 is located between the two clamping plates 333. The function of the limiting block 334 is to provide an axial positioning reference for the cylinder tail end when it approaches the clamping assembly 33, ensuring that the cylinder is in the correct axial position before clamping.

[0036] Furthermore, an encoder 35 is provided on the second slide 31 corresponding to the turntable 32. The encoder 35 is used to detect and provide feedback on the rotation angle of the turntable 32 in real time. The operator can use this information to make precise fine adjustments to the rotation angle of the cylinder, ensuring that the oil passage inside the cylinder and the structure on the piston rod can be quickly and accurately aligned.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
