Description

Technical Field

[0001] This invention belongs to the technical field of hydraulic cylinder assembly flipping fixtures, specifically relating to a universal fixture for realizing the horizontal docking and flipping of hydraulic cylinder assembly parts. Background Technology

[0002] As the core actuator of a hydraulic system, hydraulic cylinders require precise fixing and horizontal alignment during assembly. After alignment, they need frequent rotation to accommodate other components during assembly, lubrication checks, and other operational needs. For example, various actuators, dampers, and buffers all require precise alignment and rotation checks to ensure proper assembly. The accuracy of this assembly directly impacts the overall performance of the product.

[0003] The existing hydraulic cylinder parts docking and flipping mechanisms have the following technical defects: 1. Poor adaptability: Most mechanisms are specially designed with fixed structures and dimensions, which can only be used for parts of a single specification. They cannot meet the assembly requirements of parts such as cylinders and piston rods with different diameters and lengths. The mechanisms have low versatility and high cost. Second, the low docking accuracy and lack of coaxial guidance make it easy for parts to shift or tilt during docking, resulting in excessive coaxiality deviation and affecting the sealing performance of the hydraulic cylinder. Third, the flipping function is limited, the flipping angle adjustment range is narrow, and most can only achieve 180° one-way flipping, which cannot meet the needs of all-round assembly of parts. In addition, there is no locking mechanism during the flipping process, resulting in insufficient safety. Summary of the Invention

[0004] The purpose of this invention is to provide a universal tooling for horizontal docking and flipping of parts used in the assembly of hydraulic cylinders, aiming to solve the above-mentioned problems. Through modular design, adaptive support, precise docking, and flipping, it breaks through the adaptability and precision of existing mechanisms and meets the assembly needs of various types of hydraulic cylinders.

[0005] This invention is mainly achieved through the following technical solutions: A universal tooling for horizontal docking and flipping of parts used in hydraulic cylinder assembly includes a fixed base, a horizontal docking assembly, a clamping and positioning assembly, and a flipping assembly. The flipping assembly is located at the top of the fixed base, the horizontal docking assembly is located in the middle of the flipping assembly, and the clamping and positioning assembly is located at the end of the flipping assembly.

[0007] To better realize the present invention, the flipping bracket is further provided with a T-shaped structure, and a horizontal docking component is provided on the main shaft, and a clamping, positioning and fixing component is provided on the vertical shaft.

[0008] To better realize the present invention, the horizontal docking assembly further includes a second linear slide rail, a second clamping and positioning mechanism, and a second replacement fixing plate. The top of the second replacement fixing plate is slidably connected to the second clamping and positioning mechanism through the second linear slide rail. The second clamping and positioning mechanism is used to firmly clamp and position the parts to be docked.

[0009] To better realize the present invention, the clamping and positioning fixing assembly further includes a supporting V-block, a first clamping and positioning mechanism and a first replacement fixing plate. The first replacement fixing plate has a first clamping and positioning mechanism at both ends of its top, and a supporting V-block is provided on the side near the horizontal docking assembly.

[0010] To better realize the present invention, the two ends of the first replacement fixing plate are slidably connected to the first clamping and positioning mechanism via the first linear slide rail.

Specifically, the follower rotation mechanism 13, the servo motor 14, and the transmission mechanism 15 are mounted on the flipping bracket 12 along the same axis to form the flipping assembly 4. The servo motor 14 drives the flipping bracket 12 to achieve a 0-360° flipping. The flipping angular velocity is adjusted by the servo motor 14, and the reverse mounting positioning accuracy is ensured by the servo motor 14.
