Description

Technical Field

[0001] This utility model relates to the field of mechanical automation equipment technology, and in particular to an automatic locking mechanism for a cylinder. Background Technology

[0002] Currently, enterprises face multiple technical challenges when assembling large cylindrical products. These workpieces are large in size and weight, and the front and rear mating surfaces need to meet micron-level high-precision fitting requirements. Traditional assembly relies entirely on gantry cranes to repeatedly adjust the position and angle. In actual operation, it is necessary to complete the docking through multiple lifting, displacement and angle corrections. Each docking takes a long time and there is a safety hazard of the product falling due to the slippage of the lifting ropes, which seriously restricts production efficiency.

[0003] Moreover, after the docking is completed, the existing locking process uses manual circumferential tightening of bolts one by one. Since the workpiece cannot rotate on its own, workers need to move frequently on the ground, on the platform, and at the bottom of the workpiece. To lock a single piece of equipment, workers need to bend over, squat, climb, and walk long distances multiple times. This process not only prolongs the locking operation time, but also increases the probability of worker injury due to factors such as working at height and the risk of heavy objects falling. At the same time, the inability to tighten multiple bolts simultaneously can easily lead to quality problems such as sealing failure and loose connections.

[0004] Therefore, it is necessary to provide an automatic locking mechanism for cylinders to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an automatic locking mechanism for cylinders.

[0006] This utility model provides an automatic locking mechanism for a cylinder, including a support box. The support box is provided with a pair of openable and closable rotating clamps. The rotating clamps are opened and closed by a clamp opening and closing drive. A workpiece is placed inside the rotating clamps. The rotating clamps are locked into a ring by a clamp locking mechanism. The rotating clamps and the workpiece are fixedly connected by a workpiece fixing device. The angle of the rotating clamps is adjusted by a clamp rotation drive.

[0007] Preferably, after the rotary clamp is closed, it forms a semi-circular flat guide rail, a semi-circular rack, and a semi-circular V-shaped guide rail, and the two rotary clamps are fixedly connected by a connecting rod.

[0008] Preferably, the clamp opening and closing drive is achieved by a cylinder driving a swing arm to complete the opening and closing action.

[0009] Preferably, the drive gear and the semi-circular rack of the clamp rotation drive adopt an involute tooth profile design.

[0010] Preferably, the clamp rotation drive is provided with a drive gear, which meshes with a semi-circular rack.

[0011] Compared with related technologies, the automatic locking mechanism for cylinders provided by this utility model has the following advantages: This mechanism is specifically designed for large cylindrical workpieces, integrating automatic locking and precise rotation functions. During assembly, it can quickly lock and fix the workpiece, ensuring that the front and rear mating surfaces meet the micron-level high-precision fitting requirements, avoiding the time-consuming process and the risk of falls caused by repeated adjustments by overhead cranes. After docking, the mechanism automatically rotates to the designated angle, allowing workers to quickly complete the circumferential bolt locking without frequent movement, climbing, or navigating. This design significantly reduces labor intensity and safety risks, shortens the assembly time of a single unit, and significantly increases annual production capacity, achieving synergistic optimization of "safety-efficiency-quality".

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] Please refer to the following: Figs. 1-2 An automatic locking mechanism for a cylinder includes a support box 1, on which a pair of openable and closable rotating clamps 4 are provided. The rotating clamps 4 are opened and closed by a clamp opening and closing drive 5. A workpiece 3 is placed inside the rotating clamps 4. The rotating clamps 4 are locked into a ring by a clamp locking mechanism 2. The rotating clamps 4 and the workpiece 3 are fixedly connected by a workpiece fixing device 6. The angle of the rotating clamps 4 is adjusted by a clamp rotation drive 7.

[0016] In practical implementation, this mechanism is specifically designed for large cylindrical workpieces, integrating automatic locking and precise rotation functions. During the assembly stage, it can quickly lock and fix the workpiece 3, ensuring that the front and rear mating surfaces meet the micron-level high-precision fitting requirements. This avoids the time-consuming process and the risk of falling caused by repeated adjustments by the overhead crane. After the docking is completed, the mechanism automatically rotates to the specified angle, allowing workers to quickly complete the circumferential bolt locking without frequent movement, climbing, or detouring. This design significantly reduces labor intensity and safety risks, shortens the assembly time of a single machine, and significantly increases annual production capacity, achieving synergistic optimization of "safety-efficiency-quality".

[0017] refer to Fig. 2 As shown, after the rotating clamp 4 is closed, it forms a semi-circular flat guide rail 41, a semi-circular rack 42, and a semi-circular V-shaped guide rail 43, and the two rotating clamps 4 are fixedly connected by a connecting rod 44.

[0018] It should be noted that the full-circle and semi-circle flat guide rails 41, semi-circle racks 42, and semi-circle V-shaped guide rails 43 formed after the rotating clamp 4 is closed respectively undertake the functions of rotational support, power transmission, and radial guidance. The three work together to ensure that the coaxiality error of the workpiece rotation is within the micrometer level, meeting the requirements of high-precision docking. The connecting rod 44 enhances the structural rigidity of the two halves of the clamp, avoids deformation or breakage caused by stress concentration during rotation, and improves the reliability of the mechanism in long-term operation.

[0019] refer to Fig. 2 As shown, the clamp opening and closing drive 5 is driven by cylinder 51 to drive the swing arm to complete the opening and closing action.

[0020] It should be noted that the opening and closing method of the swing arm driven by cylinder 51 utilizes the rapid response characteristics of the pneumatic system to complete the opening and closing action of the clamp in a short time. The hinge structure of the swing arm ensures that the two halves of the clamp move synchronously, avoiding workpiece scraping or mechanism jamming caused by asynchronous opening and closing. The adjustable thrust of cylinder 51 is suitable for workpieces of different weights, expanding the applicability of the mechanism.

[0021] refer to Fig. 2 As shown, the drive gear 71 and the semi-circular rack 42 of the clamp rotation drive 7 adopt an involute tooth profile design.

[0022] It should be noted that the involute tooth profile design makes the meshing of the drive gear 71 and the semi-circular rack 42 more compact, improving transmission efficiency and reducing power loss caused by tooth profile errors. The involute tooth profile has strong load-bearing capacity, wear resistance, extends gear service life, reduces maintenance frequency, and is particularly suitable for long-term stable operation under heavy load conditions.

[0023] refer to Fig. 2 As shown, the clamp rotation drive 7 is equipped with a drive gear 71, which meshes with the semi-circular rack 42.

[0024] It should be noted that the direct meshing of the drive gear 71 and the semi-circular rack 42 forms a hard transmission chain, ensuring that the angle control accuracy of the synchronous rotation of the rotating clamp 4 and the workpiece 3 reaches ±0.1°, avoiding angle deviation caused by transmission clearance; the gear transmission structure is simple and reliable, with no risk of belt slippage or chain loosening, improving the stability of the rotation process and ensuring the consistency of assembly quality.

[0025] The working principle of the automatic locking mechanism for a cylinder provided by this utility model is as follows: Opening and closing positioning: The clamp opening and closing drive cylinder 5 + swing arm drive the two halves of the rotating clamp 4 to translate and open and close along the semi-circular flat guide rail 41. After the workpiece 3 is placed in, the clamp 4 is rotated and then closed to form a complete circular structure. The semi-circular V-shaped guide rail 43 provides radial guidance support, and the semi-circular flat guide rail ensures smooth opening and closing.

[0026] Locking and fixing: The clamp locking mechanism 2 mechanically locks the two halves of the clamp into a rigid ring after they are closed. The workpiece fixing device 6 fixes the workpiece 3 to the rotating clamp 4 through the upper clamping force, eliminating the risk of slippage during rotation.

[0027] Rotary drive: The clamp rotary drive 7 meshes with the semi-circular rack 42 through the drive gear 71, and transmits the torque to the full-circular rack, driving the rotating clamp 4 and the workpiece 3 to rotate synchronously to the specified angle, so that the worker can complete the circumferential assembly without moving.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
