The top of the workbench body 1 is located on the right side of the control body 2, and a torque speed sensor 11, a mounting platform component 6 and a mounting plate frame 7 are respectively installed in sequence. The steering gear body 3 is arranged above the middle of the mounting platform component 6, and a displacement sensor component 10 is installed between the left side of the mounting plate frame 7 and the right side of the control body 2. The displacement sensor 10 is mainly in the form of a grating ruler, which plays a role in the displacement of the steering gear body 3 during operation. The front end of the displacement sensor component 10 is located on the upper part of the right connecting end of the steering gear body 3 and is connected to the mounting connection component 5 The installation connection assembly 5 is respectively composed of a fixed clamp block 501, a movable clamp block 502, a butterfly nut 503, a bolt 504, a protective gasket 505, a spring 506, two groups of balls 507 and a connecting plate 508. The protective gasket 505 mainly protects the spring 506 and the butterfly nut 503 to reduce wear. The two groups of balls 507 are respectively rollingly embedded in the mutually contrasting sides of the fixed clamp block 501 and the movable clamp block 502, and the two groups of balls 507 are rollingly abutted against the two side walls of the connecting plate 508. The fixed clamp block 501 is fixedly installed at the middle front end connection of the displacement sensor assembly 10, and the movable clamp block 502 is rotatably connected to the left bottom of the fixed clamp block 501.

[0037] Embodiment 2:

[0038] Combination Figure 1 , Figure 2 and Figure 5 As shown, based on the first embodiment,

[0039] Specifically, the mounting platform assembly 6 is respectively composed of a clamping base box 601, two sets of clamping blocks 602, two sets of elastic extrusion pads 603, a second drive motor 604, two sets of threaded support columns 605, a bidirectional threaded rod 606, a slide groove 607 and a slide hole 608. The two sets of elastic extrusion pads 603 are made of silicone material, which is elastic and wear-resistant. While improving the clamping stability, they also protect the two sets of clamping blocks 602 and improve durability. The slide holes 608 and the slide groove 607 are mainly to facilitate the stable sliding of the two sets of threaded support columns 605 and play a limiting role. The second drive motor 604 is installed inside the rear end of the clamping base box 601. The bidirectional threaded rod 606 is transmission-connected to the output end of the second drive motor 604. The two sets of threaded support The column 605 is symmetrically threadedly sleeved on the outer side surface of the bidirectional threaded rod 606, and the bottom ends of the two assembly clamps 602 are respectively connected to the top ends of the two groups of threaded support columns 605, and the two groups of elastic extrusion pads 603 are respectively installed and embedded in the corresponding sides of the two assembly clamps 602. The slide groove 607 is opened on the inner bottom side of the clamping base box 601, and the slide hole 608 is opened on the top end of the clamping base box 601. The bottom of the two groups of threaded support columns 605 are slidably connected to the inner side of the slide groove 607, and the top ends of the two groups of threaded support columns 605 slide between the slide holes 608. The arrangement of the above-mentioned components enables the mounting platform assembly 6 to automatically adjust and clamp the servo bodies 3 of different sizes, which not only improves the use effect, but also improves the convenience of operation.

[0040] Combination Figure 1 As shown, in the above embodiment,

[0041] Specifically, a drawer door 4 is installed in the middle of the front end of the workbench body 1, and the drawer door 4 is mainly used to protect the main control devices inside the workbench body 1. Two groups of support column plates 8 are symmetrically installed at the bottom end of the workbench body 1, and the support plate columns 8 are mainly used to support and stabilize the entire device.

[0042] The working principle and use process of the utility model are as follows: first, when in use, the servo body 3 is first installed above the mounting platform assembly 6, and the second drive motor 604 is turned on to drive the bidirectional threaded rotating rod 606 to rotate, so that the two sets of threaded support columns 605 move laterally along the bidirectional threaded rod 606, and drive the two sets of clamping blocks 602 to move to clamp the servo bodies 3 of different sizes, and the elastic extrusion pads 603 on the two sets of clamping blocks 602 also protect and fix the servo body 3, which not only improves the fixing efficiency, but also improves the convenience of use, and also improves the overall use effect of the device. Secondly, in the above process, after the servo body 3 is fixed, through the control interface on the control body 2, the main control operating devices inside the workbench body 1 make the first drive motor 16 operate through the coupling. 9, so that the output end of the steering gear body 3 operates. After the force is generated, due to the connection between the installation connection component 5 and the steering gear body 3, the force is transmitted to the connecting plate 508 composed of the installation connection component 5. After the force is applied, due to the elastic reaction force of the spring 506 between the movable clamp block 502 and the butterfly nut 503, the spring is deformed before the connecting plate 508 is deformed, so that the rigid connection of the connecting plate 508 is converted into a flexible connection, which plays a protective role. At the same time, due to the force, the ball 507 on the movable clamp block 502 and the fixed clamp block 503 gives the connecting plate 508 an angular offset space without affecting the displacement sensor 10 for the displacement of the steering gear body 3. This not only improves the durability of the device components, but also reduces the cost of updating and maintenance, and also reduces the impact on the test effect.

[0043] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
