[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0023] Example:
[0024] like Figure 1 , Figure 2 As shown, the actuator axial test bench in this example includes a base 1 and a pulling mechanism 4 and a clamp 2 mounted on the base 1. The clamp 2 is used to hold the mechanism to be tested, such as the actuator 9. The clamp 2 can be selected from the market according to requirements, such as a vertical clamping type or a horizontal clamping type. For the pulling mechanism 4, such as a common electric cylinder, other types of pulling mechanisms can also be selected. A slide block 3 is slidably connected between the moving end of the pulling mechanism 4 and the clamp 2 at the base 1. The sliding direction of the slide block 3 is consistent with the axial direction of the actuator 9 held by the clamp 2. The slide block 3 can be slidably connected to the base 1 through a slider, slide rail, etc.
[0025] In this example, a connecting structure 5 is installed at the end of the slide 3 facing the pulling mechanism 4, so that the connecting structure 5 is connected to the moving end of the pulling mechanism 4. A connecting structure 6 is installed at the end of the slide 3 facing the clamp 2, so that the connecting structure 6 is connected to the telescopic end 91 of the actuator 9 held and fixed by the clamp 2, so that the pulling mechanism 4 moves the slide 3 and synchronously pulls the telescopic end 91 of the actuator 9 to move.
[0026] A fine-tuning slide 7 is installed on the side of the base 1 at the side of slide 3. Slide 7 is also slidably connected to the base 1 via a slider, slide rail, etc. The movement path of slide 7 is parallel to that of slide 3 to more accurately detect the axial displacement of actuator 9. A displacement detector 8, such as a commonly available sensor type, is installed on slide 7.
[0027] For example, the axial detection of the actuator 9, when the telescopic end 91 of the actuator 9 is extended to a predetermined length, the sliding seat 1 is adjusted to connect the connecting structure 1 and the telescopic end of the actuator 9, the moving end of the pulling mechanism 4 is connected with the connecting structure 2, the sliding seat 2 is slid to make the detection end of the detector 8 abut against the sliding seat 1, when the sliding seat 1 is moved by the pulling mechanism 4 with a predetermined force, the displacement of the sliding seat 1 is detected by the detector 8, and the axial displacement of the telescopic end of the actuator 9 is obtained synchronously. After the connection between the connecting structure 1 and the connecting structure 2 is released, the telescopic end of the actuator 9 can be extended to another length, and then the detection is performed again, which is convenient to operate. The telescopic end 91 of the actuator 9 can also be used as follows: the telescopic end 91 is moved forward to a predetermined position, and the sliding seat 1 is moved forward synchronously and pushes the detection end 81 of the detector back, and then the sliding seat 1 is moved backward by the pulling mechanism 4 with a predetermined force, and the movement of the sliding seat 1 is detected by the detector 8 synchronously.
[0028] In order to simplify the structure and facilitate the connection, in this example, the sliding seat 1 includes a bottom plate 31, a support plate 32 and a connecting frame 33. The support plate 32 is fixed longitudinally on the bottom plate 31, the connecting structure 2 is installed on the support plate 32, and the support plate 32 is in the movement path of the detection end 81 of the detector 8. For example, the sliding seat 2 is slid to make the detection end 81 of the detector 8 abut against the support plate 32, and then the displacement of the entire sliding seat 1 can be detected. The connecting frame 33 is installed at the end face of the support plate 32 facing the pulling mechanism 4, and the connecting frame 33 is in the form of a common square table. The connecting structure 1 is installed on the plate body of the connecting frame 33 facing the pulling mechanism 4.
[0029] The connecting structure 1 and the connecting structure 2 can be purchased from the market according to the requirements, and the structure shown in this example is preferably adopted, as shown in Figure 2 The connecting structure 2 includes a threaded stud 62 and a nut 61. The tail end of the threaded stud 62 passes through a hole formed in the support plate 32 at the end of the sliding seat 1 and is connected with the nut 61. The length of the threaded stud 62 extending from the support plate is adjusted by the nut 61. The end of the threaded stud 62 extending from the end of the sliding seat 1 (i.e. from the support plate 32) is formed with a threaded hole which is threadedly connected with the telescopic end of the actuator 9.
[0030] The connecting structure 1 includes a threaded stud 51 and a nut 52. The end of the threaded stud 51 extends from a hole formed in the end of the sliding seat 1 (i.e. on the plate body of the connecting frame) and is connected with the nut 52. The length of the threaded stud 51 extending from the plate body of the connecting frame 33 is adjusted by the nut 52. A threaded hole which is threadedly connected with the threaded stud 51 is formed at the moving end of the pulling mechanism 4, which is convenient for connection.
[0031] For the clamp 2, the clamp 2 can also be connected with the seat body 1 through a zero-point quick-change tool. The zero-point quick-change tool can be directly selected from the market according to the requirements, which is convenient for disassembling the clamp.
[0032] In order to reduce the interference of external factors, the shell 10 can also be increased, such as a common rectangular box, such as Figure 3 、 Figure 4 As shown in the figure, the seat body 1 is in the cavity of the shell 10, and the door plate 11 is installed at the side of the shell 10 to facilitate the taking and placing of the actuator 9.

It should be pointed out that for ordinary skilled in the art, without departing from the principle of the present application, some improvements and decorations, these improvements and decorations should also be considered as the protection scope of the present application.
