The objectives of the run-in test, including parameters such as run-in time, run-in load, and run-in speed, must be clearly defined based on the actuator's design requirements and actual operating conditions.

[0024] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] An embodiment of the present application provides an actuator running-in test device, which can solve the technical problem in the prior art that, during the closed-loop running-in test of the actuator, the test bench lacks a limiting means for the telescopic end of the actuator, resulting in easy movement deviation when the telescopic end of the actuator performs telescopic movement, thereby reducing the test accuracy.

[0026] The actuator running-in test device in this application includes a fixing component and a limiting component, wherein the fixing component is used to fix the fixed end of the actuator, simulate the actual installation method of the actuator, and ensure the basic stability of the actuator. The limiting component is arranged on the fixing component, and is mainly used to follow the movement of the telescopic end of the actuator and produce a limiting effect on the telescopic end of the actuator.

[0027] Specifically, Figure 1 A top view of an actuator running-in test device provided in an embodiment of the present application. Figure 2 This is a front view of an actuator running-in test device provided in an embodiment of the present application, as shown in FIG. Figure 1 、 Figure 2 As shown, the fixed component in the actuator running-in test device provided by the present application includes two relatively arranged limit cross plates 1, and an actuator connecting unit 2 is provided at one end of the limit cross plates 1. During actual use, the two limit cross plates 1 are arranged in parallel and at a certain distance from each other, and the limit cross plates 1 and the actuator are set in the same direction. One end of the two limit cross plates 1 is close to the actuator and clamped on both sides of the fixed end of the actuator, and the telescopic end of the actuator performs telescopic and translational motion in the gap between the two limit cross plates 1.

[0028] Furthermore, the limiting assembly includes a sliding groove 3 opened on the limiting horizontal plate 1 and arranged along the length direction of the limiting horizontal plate 1, and a follower sliding rod 4 with both ends respectively located in the two sliding grooves 3. A telescopic end clamp 5 is provided on the rod body of the follower sliding rod 4. After assembly is completed, the follower sliding rod 4 is perpendicular to the telescopic end of the actuator and is detachably connected to the telescopic end of the actuator. There are many ways to detach and connect the follower sliding rod 4 and the telescopic end of the actuator, which are not limited in this application.

[0029] The two ends of the follower sliding rod 4 are arranged in the two sliding grooves 3. The length of the sliding groove 3 is set according to the preset stroke of the actuator. When the telescopic end of the actuator moves, the follower sliding rod 4 moves horizontally in the two sliding grooves 3. The cooperation of the two sliding grooves 3 can ensure that the follower sliding rod 4 can only perform a horizontal movement, thereby limiting and guiding the motion track of the telescopic end of the actuator. The telescopic end clamping piece 5 is arranged on the rod body of the follower sliding rod 4. After the assembly is completed, the telescopic end clamping piece 5 clamps the connection between the telescopic end of the actuator and the follower sliding rod 4, which can produce a further limiting effect on the telescopic end of the actuator.

[0030] Furthermore, the actuator connection unit 2 includes an actuator connection hole 201 opened at one end of the limiting horizontal plate 1, and a connecting bolt 202 for passing through the actuator is provided in the actuator connection hole 201. Each limiting horizontal plate 1 is provided with an actuator connection hole 201 at one end close to the actuator. The actuator connection hole 201 passes through the plate body of the limiting horizontal plate 1, and the connecting bolt 202 passes through the actuator and the actuator connection hole 201 horizontally. In the present application, the connecting bolt 202 can be a whole setting that passes through the two actuator connection holes 201 and the actuator at the same time, or it can be two settings. The two connecting bolts 202 are connected to one side of the actuator through an actuator connection hole 201 respectively. No specific restrictions are made here.

[0031] Furthermore, the two ends of the follower sliding rod 4 extend out of the two sliding grooves 3 respectively, and the end of the follower sliding rod 4 extending out of the sliding groove 3 is detachably provided with a rod body fixing unit 6. The length of the follower sliding rod 4 is greater than the spacing distance between the two limiting horizontal plates 1. After the assembly is completed, the two ends of the follower sliding rod 4 pass through the two sliding grooves 3 and the rod body fixing unit 6 is provided at the end of the follower sliding rod 4 passing through the two sliding grooves 3, thereby realizing a detachable connection between the follower sliding rod 4 and the two limiting horizontal plates 1.

[0032] Specifically, Figure 3 A top view of a limit assembly in an actuator running-in test device provided in an embodiment of the present application, as shown in FIG. Figure 3As shown, the rod body fixing unit 6 includes an anti-falling sleeve 601 which is sleeved on the rod body of the follower sliding rod 4 and located on the outside of the limiting horizontal plate 1. The diameter of the anti-falling sleeve 601 is larger than the width of the sliding groove 3. The anti-falling sleeve 601 is arranged in a through shape and the inner diameter of the anti-falling sleeve 601 is larger than the outer diameter of the follower sliding rod 4, so that it is used to be sleeved on the outer periphery of the follower sliding rod 4. The axial length of the anti-falling sleeve 601 is smaller than the rod body length of the follower sliding rod 4 extending out of the limiting horizontal plate 1. At the same time, the diameter of the anti-falling sleeve 601 is larger than the width of the sliding groove 3, which can prevent the anti-falling sleeve 601 from passing through the sliding groove 3, causing the follower sliding rod 4 to fall off from the sliding groove 3.

[0033] The end of the follower sliding rod 4 is also removably provided with a sleeve fixing part 602 located on the outside of the telescopic anti-falling sleeve 601. The sleeve fixing part 602 is arranged at the outermost end of the rod body of the follower sliding rod, and is used to fix the position of the anti-falling sleeve 601 on the rod body of the follower sliding rod 4, and adjust the distance between the anti-falling sleeve 601 and the outside of the limiting horizontal plate 1 to ensure that the follower sliding rod 4 can follow the movement of the telescopic end of the actuator and move normally in the sliding groove 3.

[0034] The connection method between the sleeve fixing part 602 and the follower sliding rod 4 is diversified. In one embodiment of the present application, in order to improve the convenience of disassembly of the follower sliding rod 4, the sleeve fixing part 602 is a longitudinally arranged limit pin shaft. At the same time, a limit hole is longitudinally opened at the end of the follower sliding rod 4, and the limit pin shaft passes through the limit hole.

[0035] Furthermore, the follower sliding rod 4 has a certain length, and the telescopic end clamping member 5 includes two spaced apart limit sleeves 501, the limit sleeves 501 are sleeved on the outside of the rod body of the follower sliding rod 4 and the limit sleeves 501 are located between the two limit horizontal plates 1, there are two limit sleeves 501 and the two limit sleeves 501 are sleeved on the periphery of the rod body of the follower sliding rod 4 located between the two limit horizontal plates 1. After the assembly is completed, one end of the limit sleeve 501 abuts against the inner wall of the limit horizontal plate 1, and the other end abuts against the telescopic end of the actuator, which can prevent the connection between the telescopic end of the actuator and the follower sliding rod 4 from loosening, causing the telescopic end of the actuator to be slightly displaced or rotated.

[0036] Furthermore, the fixing assembly also includes a reinforcement unit, which includes an end fixing plate 7 respectively connected to one end of the two limiting horizontal plates 1 where the actuator connection unit 2 is not provided. The end fixing plate 7 is arranged longitudinally, and one side thereof is connected to the two limiting horizontal plates 1. This can be a detachable connection to improve the convenience of structural installation and disassembly, or it can be a fixed connection to improve the structural integrity and stability. No specific requirements are made here.

[0037] Furthermore, the fixing assembly also includes a support base 8 located at the bottom of the limiting horizontal plate 1. The support base 8 is located at the bottom of the entire structure. During the experiment, the support base 8 is placed on the bearing surface, and the top of the support base 8 is connected to the bottom surfaces of the two limiting horizontal plates 1. The support base 8 can be integral or split, that is, the support base 8 includes two independent support parts, each of which is connected to the bottom of a limiting horizontal plate 1. No specific restrictions are made in this application.

[0038] It should be noted here that the actuator running-in test also includes a control system for controlling various parameters of the test bench, such as loading force, loading speed, test time, etc., to achieve accurate running-in tests, and a data acquisition system for real-time collection of various data of the actuator during the test process through sensors and other devices, such as displacement, velocity, acceleration, temperature, etc., for subsequent analysis and evaluation. Other action systems, such as the multiple action systems, are used in conjunction with the actuator precision simulation experimental device in this application to complete the closed-loop control of the actuator running-in test. The above-mentioned systems have no direct connection with this application and all adopt common means of existing technologies, which will not be elaborated here.

[0039] The actuator running-in test device in the present application is capable of stably connecting the fixed end of the actuator by arranging an actuator connection unit 2 at one end of the limiting horizontal plate 1. By arranging a sliding groove 3 on the plate body of the limiting horizontal plate 1 and a telescopic end clamp 5 on the follow-up sliding rod 4, the fixed end and the telescopic end of the actuator can be fixed and limited through the combined action of the structures and mutual cooperation, thereby ensuring that the actuator always maintains the preset direction and stroke movement during the experiment, preventing abnormal displacement and change of the telescopic end of the actuator, and ensuring the accuracy of the test results.
