DETAILED DESCRIPTION

[0017] The specific implementation methods of the utility model are further described in detail below in combination with the accompanying drawings. However, the following embodiments only list preferred embodiments, which only serve to explain and help understand the utility model and cannot be understood as limiting the utility model.

[0018] refer to Figure 1-2 A balancing cylinder test bench, the balancing cylinder includes a main cylinder body 1 and pressure storage cylinders 2 symmetrically arranged on both sides thereof, a piston rod 3 is arranged inside the cylinder body, a first connecting ring 4 is arranged at one end of the cylinder body, and a second connecting ring 5 is arranged at the end of the piston rod at the other end, the test bench includes a driving test unit 100 and a fixing unit 200, the driving test unit includes an RV reducer 120 inputting power through a servo motor 110, the output shaft of the RV reducer is connected with an eccentric rod 130, the eccentric rod 130 includes a main rod body 131, one end of the main rod body is a power connecting end 132 connected to the output shaft of the RV reducer, the other end of the main rod body is upwardly provided with a balancing cylinder connecting end 133 connected to the first connecting ring 4, and downwardly provided with a limiting rod 134, the limiting rod is arranged in an arc-shaped limiting groove 141 on the table 140. The fixing unit includes a fixing column 210 for fixing the second connecting ring.

[0019] The balancing cylinder test bench of the present technical solution realizes efficient and accurate testing of the balancing cylinder performance through a series of carefully designed components and functions. The introduction of the servo motor 110 not only provides a stable and powerful power source, but also can accurately adjust the movement angle of the cylinder through its precise control ability, which greatly facilitates the operation and data recording during the test process. This precise power control is crucial to ensure the accuracy of the test results.

[0020] The use of RV reducer 120 further improves the operating accuracy of the entire system while increasing the torque. This design not only ensures that the swing amplitude and frequency of the eccentric rod 130 meet the test requirements, but also improves the load capacity and stability of the system by reducing the speed and increasing the torque, so that the test bench can adapt to the balance cylinder test of different specifications and performance requirements.

[0021] The design of the eccentric rod 130 cleverly combines the power connection end 132 and the balance cylinder connection end 133, as well as the coordinated use of the limit rod 134 and the arc-shaped limit groove 141, which not only realizes the effective support and limitation of the eccentric rod, prevents deformation and interference during movement, but also ensures the stability and reliability during the test through this structural design.

[0022] In addition, the fixing column 210 in the fixing unit 200 provides a stable fixing point for the second connecting ring 5, further enhancing the stability and repeatability of the test. The operation is simple and intuitive, and the user only needs to replace the balance cylinder to be tested to quickly perform the performance test, avoiding the cumbersome procedures of traditional testing on the robot, greatly improving the test efficiency and convenience.

[0023] The balance cylinder test bench of this technical solution, through its innovative design and precise control, not only improves the efficiency and accuracy of the test, but also simplifies the operation process and reduces the test preparation time, providing an efficient and reliable solution for the performance test of the balance cylinder. The application of this test bench will greatly promote the research and development and quality control of balance cylinder products, and improve production efficiency and product competitiveness.

[0024] As a preferred technical solution, the RV reducer 120 is supported on the table 140 by an arc-shaped support plate 150, and the opening of the arc-shaped support plate faces the side of the eccentric rod. The table 140 is supported and fixed to the test unit bottom plate 170 by table legs 160. The fixing column 210 is supported and fixed to the fixing unit bottom plate 230 by fixing unit legs 220. The second connecting ring 5 is fixed to the fixing column 210 by a cover plate 240 and bolts 250.

[0025] The above technical solution significantly improves the performance and operation convenience of the balance cylinder test bench through a series of optimized designs. Among them, the RV reducer 120 is supported by the arc support plate 150, which not only ensures its stability, but also the arc design helps to evenly distribute the force and reduce the pressure on the table 140. This layout makes the power transmission more direct and effective, while optimizing the space utilization and making the workbench structure more compact.

[0026] The table 140 and the fixing column 210 are supported and fixed on the bottom plates 170 and 230 respectively through their respective legs 160 and 220. This double-layer support structure not only provides the flexibility of height and angle adjustment, but also enhances the stability and durability of the entire test bench. The fixing method of the second connecting ring 5, through the combination of the cover plate 240 and the bolt 250 with the fixing column 210, simplifies the installation and replacement process of the balance cylinder and improves the convenience of operation.

[0027] In addition, the design of the limit rod 134 and the arc-shaped limit groove 141 effectively prevents the deformation and interference of the eccentric rod during movement, ensuring the stability and reliability of the test. The modular design of the entire test bench facilitates maintenance and upgrading, improves safety and adaptability, and can meet the testing needs of balance cylinders of different specifications and performance requirements, providing users with an efficient, accurate and easy-to-operate test solution.

[0028] The embodiments described above are merely descriptions of preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
