[0026] The following is combined with Figure 1-6 The embodiments of the present invention are described in detail, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to explain the principles of the present invention, but are not used to limit the scope of the present invention. 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 the present invention.

[0027] The schematic diagram of the structural principle of the linear servo loading device of this embodiment is as follows: Figure 1 As shown, the loading device includes a base plate 3, a steering gear mounting assembly 100, a first connecting member 5, a second connecting member 11, a pulley 10 and a pulley support 8. The steering gear mounting assembly 100 is fixed on the base plate 3 and is used to install the linear steering gear during testing; there are two steering gear mounting assemblies 100, which are staggered with each other; the two ends of the first connecting member 5 are respectively used to connect the linear steering gear and the traction member 7, and the two ends of the second connecting member 11 are respectively used to connect the traction member 7 and the weight 12; the pulley 10 and the pulley support 8 are used for the rotation support of the traction member 7. In this embodiment, preferably, the steering gear mounting assembly 100 includes a steering gear mounting plate 101 and a steering gear support plate 104, which are arranged in pairs, and there are two pairs, which are respectively fixed on the base plate 3. The two ends of the linear steering gear have rod end bearings, and are respectively connected to the steering gear mounting plate 101 and the steering gear support plate 104 through the rod end bearings and the pin shaft components 2. In addition, a deep groove ball bearing is installed in the pulley support 8.

[0028] like Figure 2 , Figure 4 As shown, the first connecting member 5 is provided with three traction member connection structures, arranged in left, middle and right order; the middle traction member connection structure 51 is used to connect the linear servo 6, and the other two traction member connection structures (52, 53) are respectively used to connect the traction member 7, and the weight 12 is connected through the traction member 7. The traction member 7 is a traction steel cable, which is respectively connected to the first and second connecting members (5, 11) in a detachable manner. Preferably, the traction member 7 also includes a wire locker 9 for convenient disassembly and assembly, which is convenient to operate and can be locked securely.

[0029] like Figure 3As shown, the bottom plate 3 is provided with a slide groove 301, and the first connecting member 5 includes a slide groove connecting portion 501 and a traction member connecting portion 502. The first connecting member 5 is arranged on the bottom plate 3 through the slide groove connecting portion 501, and can slide in the slide groove 301. The traction member connecting portion 502 is used to connect the traction member 7 and the linear servo 6. The mutual cooperation between the slide groove connecting portion 501 and the slide groove 301 has a guiding effect, which can increase the stability of the equipment operation and make each test have good consistency.

[0030] The working principle of the linear servo loading device of this embodiment is described as follows:

[0031] When performing a tensile test, Figure 5 As shown, the two ends of the linear servo 6 are respectively connected to the servo mounting plate 101 and the servo support plate 104 of one of the servo mounting assemblies 100, the middle traction member connecting structure 51 is connected to the linear servo 6, and the other two traction member connecting structures (52, 53) are respectively connected to the traction member 7, and connected to the weight 12 through the traction member 7. At this time, the force applied by the weight 12 to the linear servo 6 through the traction member 7 and the first connecting member 5 is a tensile force. When performing a thrust test, as shown in FIG. Figure 6 As shown, the two ends of the linear servo 6 are respectively connected to the servo mounting plate 101 and the servo support plate 104 of another servo mounting assembly 100, the middle traction member connection structure 51 is used to connect the linear servo 6, and the other two traction member connection structures (52, 53) are respectively used to connect the traction member 7, and the weight 12 is connected through the traction member 7. At this time, the force applied by the weight 12 to the linear servo 6 through the traction member 7 and the first connection member 5 is thrust. Figure 5 and Figure 6 It can be seen that the installation positions of the servo mounting plates 101 and the servo support plates 104 of the two servo mounting assemblies 100 are interchanged left and right, so that the directions of the linear servo 6 after installation corresponding to the tension test and the thrust test are interchanged left and right, and then the direction of the force received by the linear servo 6 from the traction member 7 during the tension test is opposite to that during the thrust test. The embodiment of the present application does not require a complex hydraulic source or elastic loading components. It only needs a simple structure to solve the problem that the loading device of the prior art causes the servo load force to change linearly and cannot provide a constant load. Its loading device can provide a constant load stably for a long time, and can be more convenient to carry out bidirectional loading, and it also has the advantages of constant load and good consistency during bidirectional loading.
