[0060] The application of the above-mentioned adjustable fixture has at least the following beneficial effects: the electric drive structure is clamped by three clamping members 270, and the second adjusting member 250 is moved along the X-axis direction on the first adjusting member 240 to realize the movement of the electric drive structure to be tested along the X-axis direction. The multiple second adjusting members 250 are independent of each other on the first adjusting member 240 and are different from each other in the X-axis direction. Therefore, the X-axis direction spacing between the multiple clamping members 270 can be changed. The multiple lifting components 260 are moved along the Y-axis direction on the second adjusting member 250 to change the Y-axis direction spacing between the multiple clamping members 270, thereby adapting to the clamping of electric drive structures to be tested of various specifications. At the same time, the multiple lifting components 260 can be independently adjusted to lift and lower for leveling, or lifted and lowered at the same time to make the electric drive structure to be tested flush with the test device.

[0061] According to some embodiments of the present invention, the first adjusting member 240 is configured as two parallel first slide rails, and two parallel first T-slots 241 are provided on the first slide rails along the X-axis direction. The second adjusting member 250 is movably provided in the first T-slot 241, and a first slider 242 is movably provided in the first T-slot 241. The second adjusting member 250 is provided with a bolt, and the lower end of the bolt is connected to the first slider 242. The first slider 242 can slide in the first T-slot 241. The second adjusting member 250 is connected to the first slider 242 through the bolt. Under the action of the first slider 242, the second adjusting member 250 can also slide along the first T-slot 241, that is, it can move along the X-axis direction. The multiple second adjusting members 250 move independently of each other, so that the multiple second adjusting members 250 can produce different displacements in the X-axis direction, thereby causing the spacing between the multiple clamping members 270 along the X-direction to change.

[0062] According to some embodiments of the present invention, a plurality of support members 230 are provided, and the plurality of support members 230 are divided into two groups. The two groups of support members 230 are respectively used to support the two first slide rails. In this embodiment, three support members 230 are provided in each group, and the three support members 230 are arranged in an array below the first slide rail. The support members 230 are movably provided on the base 700. The base 700 is provided with third T-slots 701 arranged in an alternating manner along the X-axis direction and the Y-axis direction. The lower end of the support member 230 is movably connected to the third T-slot 701 by a bolt, and the bolt is movably provided in the third T-slot 701 to ensure that the support member 230 can move along the third T-slot 701 in the X-axis direction or the Y-axis direction during adjustment, and no displacement in other directions will occur.

[0063] According to some embodiments of the present invention, the second adjustment member 250 is configured as a second slide rail, and two parallel second T-slots 251 are provided on the second slide rail along the Y-axis direction. The lifting assembly 260 is movably provided on the second T-slot 251. The plurality of second adjustment members 250 are arranged parallel to each other.

The mounting seat 261 can move along the second T-slot 251 on the second adjusting member 250, that is, move along the Y-axis direction. The multiple lifting components 260 move independently of each other, that is, the multiple mounting seats 261 move independently of each other in the Y-axis direction, so that the Y-axis direction spacing between the multiple clamping members 270 on the multiple mounting seats 261 changes. Combined with the above-mentioned X-axis direction spacing change, the multiple clamping members 270 can be adapted to install a variety of electric drive structures of different specifications, the versatility of the adjustable fixture is enhanced, and there is no need to prepare multiple sets of different fixtures for testing, which saves storage costs and time for replacing fixtures and improves testing efficiency.

[0064] According to some embodiments of the present invention, it also includes a splint 2611, and a side opening is set on the mounting seat 261. The splint 2611 is set on both sides of the opening, and the splint 2611 is connected by bolts. The splint 2611 is used to compress the screw 263. When the height of the electric drive structure needs to be adjusted, the bolts at the splint 2611 are loosened to make the two splints 2611 in a relaxed state. At this time, the mounting seat 261 is in a relaxed state. The rotating part 262 is rotated to rotate the screw 263 while driving the mounting seat 261 to move up and down to the height that needs to be adjusted. Then the bolts are tightened so that the splint 2611 clamps the mounting seat 261, thereby clamping the screw 263 and the rotating part 262 so that the two cannot rotate, thereby locking the entire lifting assembly 260 to keep the electric drive structure at the corresponding height.

[0065] According to some embodiments of the present invention, a second slider 252 is movably provided in the second T-slot 251, and a bolt is provided on the mounting seat 261. The lower end of the bolt is connected to the second slider 252. The second slider 252 can slide in the second T-slot 251, and the second T-slot 251 guides the second slider 252 to ensure that the second slider 252 can only slide along the Y-axis direction. The mounting seat 261 is connected to the second slider 252 by bolts, so that the mounting seat 261 can move along the Y-axis direction in the second T-slot 251.

The handle 720 is used to drive the screw structure 710 to rotate, so that the support frame 310 moves on the base 700. Before the test, The handle 720 is used to drive the lead screw structure 710 to rotate, so that the dynamometers 320 on both sides of the warehouse body 210 are driven by the support frame 310 to move away from the warehouse body 210. After the electric drive structure is placed in the warehouse body 210, the handle 720 is used to drive the lead screw structure 710 to rotate in the opposite direction, so that the two support frames 310 move toward the warehouse body 210, thereby moving the two dynamometers 320 toward the warehouse body 210, and the output shafts of the dynamometers 320 extend into the warehouse body 210 to test the electric drive structure.
