Compared with the prior art, the embodiment of the present invention provides a mounting groove 420 at a position corresponding to the U-shaped opening 310 on the side wall of the mounting plate 400, so that the side-mounted motor 600 can be positioned and clamped on the mounting groove 420, and the side-mounted motor 600 is fixed to the mounting plate 400 by bolts and nuts, thereby realizing the function of locking and mounting the side-mounted motor 600 on the fixture. By providing waist-shaped holes 410 for bolts to pass through on the side wall of the mounting plate 400, the upper and lower mounting positions of the mounting plate 400 on the vertical plate 300 can be adjusted, thereby realizing the function of adjusting the center height of the output shaft of the dynamometer on the test bench according to the mounting position requirements of the side-mounted motor 600. At the same time, since the lead screw 110 is rotatably connected to the mounting table 100, the lead screw nut seat can move left and right relative to the lead screw 110. According to different models of side-mounted motors 600, by rotating the hand wheel 120, the side-mounted motor 600 can be moved in the left and right direction, and the relative position of the side-mounted motor 600 and the dynamometer can be adjusted. When the side-mounted motor 600 is connected to the dynamometer, the rated parameters of the motor speed, torque, voltage, current, etc. can be tested, and the connection and installation with the dynamometer can be carried out more quickly and accurately, and the test is more convenient, and the production efficiency is higher.

[0032] like Figure 5 As shown, in some embodiments of the present invention, four waist-shaped holes 410 are provided, and the four waist-shaped holes 410 are respectively provided at the four corners of the side wall of the mounting plate 400. In this way, the four corners of the mounting plate 400 are fixed to the vertical plate 300 by bolts and nuts, so that the mounting plate 400 is stably and evenly connected to the vertical plate 300, and the stability of the side-mounted motor 600 connected to the fixture is improved.

[0033] like Figure 2 , Figure 3 and Figure 4As shown, in some embodiments of the present invention, a reinforcing plate 500 is provided between the vertical plate 300 and the sliding plate 200, one end of the reinforcing plate 500 is connected to the side wall of the vertical plate 300, and the other end is connected to the upper end of the sliding plate 200, forming a triangular structure. By providing the reinforcing plate 500, the vertical plate 300, the reinforcing plate 500 and the sliding plate 200 form a triangular structure, thereby improving the connection strength between the vertical plate 300 and the sliding plate 200, and preventing the vertical plate 300 from being deformed due to the gravity of the side-mounted motor 600, thereby affecting the test quality. Specifically, the reinforcing plate 500 is provided at one end of the side of the vertical plate 300 close to the side-mounted motor 600.

[0034] Furthermore, the vertical plate 300, the sliding plate 200 and the reinforcing plate 500 are integrally formed, thereby reducing the assembly process of the fixture, thereby reducing the assembly error, improving the accuracy of the fixture, and thus improving the test accuracy.

[0035] like Figure 4 and Figure 5 As shown, in some embodiments of the present invention, a plurality of second through holes 430 are provided on the side wall of the mounting plate 400, and the second through holes 430 are provided for bolts to pass through and cooperate with nuts to fix the side-mounted motor 600. A mounting hole is provided on the side of the side-mounted motor 600 at a position corresponding to the second through hole 430, and the bolts pass through the mounting hole and the second through hole 430 and are screwed with the corresponding nuts, so that the side-mounted motor 600 is fixed on the mounting plate 400; the connection is made by the way of bolt and nut cooperation, the connection is not easy to loosen, and it is easy to disassemble and assemble. When the test is completed, the side-mounted motor 600 can be removed from the mounting slot 420 of the mounting plate 400 by simply unscrewing the bolts and nuts.

[0036] Further, four second through holes 430 are provided, and the four second through holes 430 are provided along the edge of the mounting groove 420. Through the cooperation and connection of four bolts and nuts, the side-mounted motor 600 can be stably connected to the mounting plate 400.

[0037] like Figure 2 , Figure 3 and Figure 4As shown, in some embodiments of the present invention, the hand wheel 120 includes a handle 121 and a round wheel 122, the round wheel 122 is coaxially connected to the lead screw 110, and the diameter of the handle 121 rotating around the axis of the round wheel 122 is larger than the diameter of the lead screw 110. By setting the diameter of the handle 121 rotating around the axis of the round wheel 122 to be larger than the diameter of the lead screw 110, when the operator drives the round wheel 122 to rotate through the handle 121, the rotation speed of the lead screw 110 is faster, the left and right moving speed of the lead screw nut seat is increased, and then the moving speed of the side-mounted motor 600 is increased, and the connection and installation efficiency of the side-mounted motor 600 and the dynamometer is further improved.

[0038] like Figure 4 and Figure 5 As shown, in some embodiments of the present invention, two guide rails 130 are arranged on the mounting platform 100 along the left and right directions, and the two guide rails 130 are arranged on the front and rear sides of the lead screw 110, and the front and rear sides of the lower end of the sliding plate 200 are provided with sliding grooves matching the guide rails 130. In the process of the lead screw 110 driving the sliding plate 200 to move along the left and right directions through the lead screw nut seat under the drive of the hand wheel 120, the two guide rails 130 play a guiding role for the sliding plate 200, ensuring that the sliding plate 200 moves smoothly along the left and right directions. Thereby, the accurate movement of the side-mounted motor 600 in the left and right directions is realized.
