[0053] Applying the above 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 moves along the X-axis direction on the first adjusting member 240, realizing the movement of the electric drive structure to be measured along the X-axis direction. The multiple second adjusting members 250 are independent of each other on the first adjusting member 240 and have different positions along the X-axis direction, so the X-axis direction spacing between the multiple clamping members 270 can be changed. By moving the multiple lifting assemblies 260 along the Y-axis direction on the second adjusting member 250, the Y-axis direction spacing between the multiple clamping members 270 can be changed, so as to adapt to the clamping of electric drive structures to be measured with various different specifications. At the same time, the multiple lifting assemblies 260 can be independently adjusted in height for leveling, or lifted or lowered simultaneously to make the electric drive structure to be measured flush with the testing device.

[0054] According to some embodiments of the present invention, the first adjusting member 240 is provided as two parallel first slide rails. Two parallel first T-shaped grooves 241 are provided along the X-axis direction on the first slide rails. The second adjusting member 250 is movably arranged in the first T-shaped groove 241. A first slider 242 is movably arranged in the first T-shaped groove 241. A bolt is provided on the second adjusting member 250, and the lower end of the bolt is connected to the first slider 242. The first slider 242 can slide in the first T-shaped groove 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-shaped groove 241, that is, it can move along the X-axis direction. The multiple second adjusting members 250 move independently of each other, so that different displacements can be generated by the multiple second adjusting members 250 in the X-axis direction, thereby changing the spacing between the multiple clamping members 270 in the X direction.

[0055] According to some embodiments of the present invention, a plurality of support members 230 are provided. 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, each group of support members 230 has three. The three support members 230 are arranged in an array below the first slide rail. The support members 230 are movably arranged on the base 700. Third T-shaped grooves 701 are respectively provided along the X-axis direction and the Y-axis direction on the base 700 in a staggered manner. The lower ends of the support members 230 are movably connected to the third T-shaped grooves 701 through bolts. The bolts are movably arranged in the third T-shaped grooves 701 to ensure that the support members 230 can move along the third T-shaped grooves 701 in the X-axis direction or the Y-axis direction during adjustment and will not generate displacements in other directions.

[0056] According to some embodiments of the present utility model, the second adjusting member 250 is provided as a second slide rail. There are two parallel second T-shaped grooves 251 provided along the Y-axis direction on the second slide rail. The lifting assembly 260 is movably arranged in the second T-shaped grooves 251.

The top of the screw rod 263 is provided with a mounting plate 2631, and a clamping member 270 is arranged on the mounting plate 2631. The mounting seat 261 can move along the second T-shaped grooves 251 on the second adjusting member 250, that is, move along the Y-axis direction. A plurality of lifting assemblies 260 move independently of each other, that is, a plurality of mounting seats 261 move independently in the Y-axis direction, so that the distance between a plurality of clamping members 270 on a plurality of mounting seats 261 in the Y-axis direction changes. Combining with the above-mentioned change in the distance in the X-axis direction, a variety of electric drive structures with different specifications can be adaptively installed between a plurality of clamping members 270, enhancing the versatility of the adjustable fixture. There is no need to prepare multiple sets of different fixtures for testing, saving storage costs and the time for replacing fixtures, and improving the testing efficiency.

[0057] According to some embodiments of the present utility model, it further includes a clamping plate 2611. The side of the mounting seat 261 is provided with an opening. The clamping plate 2611 is arranged on both sides of the opening. The clamping plate 2611 is connected by bolts. The clamping plate 2611 is used to press the screw rod 263. When it is necessary to adjust the height of the electric drive structure, loosen the bolts at the clamping plate 2611 to make the state between the two clamping plates 2611 loose. At this time, the mounting seat 261 is in a loose state. While rotating the rotating member 262 to make the screw rod 263 rotate, drive the mounting seat 261 to move up and down to the required height. Then tighten the bolts to make the clamping plate 2611 play a clamping role on the mounting seat 261, so as to clamp the screw rod 263 and the rotating member 262, so that the two cannot rotate, thereby locking the entire lifting assembly 260 to keep the electric drive structure at the corresponding height.

A bolt is arranged on the mounting seat 261, and the lower end of the bolt is connected to the second slider 252. The second slider 252 can slide in the second T-shaped groove 251. The second T-shaped groove 251 plays a guiding role for 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 through the bolt, so that the mounting seat 261 can move along the Y-axis direction in the second T-shaped groove 251.

The handle 720 is used to drive the lead screw structure 710 to rotate, so that the support frame 310 moves on the base 700. Before the test, by driving the lead screw structure 710 to rotate through the handle 720, the dynamometers 320 on both sides of the bin body 210 move away from the bin body 210 under the drive of the support frame 310. After placing the electric drive structure in the bin body 210, by driving the lead screw structure 710 to rotate in the reverse direction through the handle 720, the two support frames 310 move towards the bin body 210, so that the two dynamometers 320 move towards the bin body 210, and the output shafts of the dynamometers 320 extend into the bin body 210 to test the electric drive structure.
