DETAILED DESCRIPTION

[0025] The present invention will be further described below with reference to the embodiments and accompanying drawings: Example 1

[0026] like Figure 1 、 Figure 2 and Figure 3As shown, the horizontal inspection auxiliary support device for a vertical motor 6 includes a bracket, a positioning mechanism, and a centering mechanism. The positioning mechanism comprises a positioning plate 31 and a frame. The frame comprises side panels 21. In this embodiment, the frame is a U-shaped structure formed by rotating four side panels 21. The positioning plate 31 is welded to the frame, and the positioning plate 31 and the frame are connected as a whole.

[0027] Each side of the frame is equipped with a bracket, which includes a base 11, a support plate 12, and a reinforcement plate 13. The base 11 is arranged horizontally, while the support plate 12 and reinforcement plate 13 are arranged vertically. The base 11, support plate 12, and reinforcement plate 13 are arranged perpendicular to each other and fixedly connected. The two side panels 21 on either side of the frame have through-holes. The support plate 12 of each bracket has mounting holes corresponding to the mounting holes on the frame side panels 21. Bolts pass through the mounting holes in the support plates 12 and side panels 21 to securely connect the frame, positioning plate 31, and the two brackets.

[0028] Since the motor 6 is very heavy, in order to ensure that the entire auxiliary support device can stably support the motor 6 installed on the positioning plate 31. In this embodiment, the length of the base 11 and the support plate 12 is greater than 1 meter. In order to reduce the weight of the support plate 12, a through-weight reduction hole 121 is also opened on the support plate 12. In order to make the auxiliary support device more stable, a through-mounting hole is opened on the base 11. Bolts are passed through the mounting holes on the base 11 to fix the base 11 to the experimental base plate 9.

[0029] like Figures 2 to 4 As shown, the positioning plate 31 is provided with a through mounting hole and a positioning hole 32, and the positioning holes 32 are distributed in the circumferential direction of the mounting hole, and the diameter of the mounting hole is larger than the diameter of the rotating shaft 61 of the motor 6. The positioning hole 32 of the positioning plate 31 of this embodiment is a waist-shaped hole, and the length direction of the waist-shaped hole is the radial direction of the mounting hole on the positioning plate 31.

[0030] The positioning mechanism is mounted on the bracket, and the centering mechanism is mounted on the positioning mechanism. The centering mechanism includes more than three groups of adjustment mechanisms. In this embodiment, four groups of adjustment mechanisms constitute the centering mechanism. The adjustment mechanism includes a scale rod 41, an end block 42, and a centering base 43. The centering base 43 is evenly distributed in the circumferential direction of the mounting hole, and the centering base 43 is fixedly connected to the positioning plate 31. A groove is formed on the centering base 43, and the scale rod 41 is movably embedded in the groove of the centering base 43. The scale rod 41 is provided with a scale, and one end of the scale rod 41 is fixedly connected to the end block 42. Threaded holes are formed on both sides of the centering base 43. Tightening the hand screws in the threaded holes can compress the scale rod 41 and prevent the scale rod 41 from sliding in the groove of the center base 11.

[0031] like Figures 1 to 6As shown, before testing various parameters of the vertical motor 6 or the horizontal motor 6, the support shield 7, the torque meter 8 and the auxiliary support device are first installed on the experimental base plate 9, so that the center of the mounting hole of the positioning plate 31 of the auxiliary support device is at the same height as the center of the coupling.

[0032] The end cover of the motor 6 includes a flange plate 51 and a flange rib 52, and a flange plate 51 is fixedly connected to each side of the flange rib 52. A through mounting hole is opened on the flange plate 51 of the end cover of the motor 6, and multiple groups of mounting holes of the flange plate 51 are evenly distributed in the circumferential direction of the end cover. In this embodiment, there are two mounting holes in each group, and the installation of the same group is also distributed along the radial direction of the circular flange plate 51 of the end cover. The bolts pass through the positioning hole 32 of the positioning plate 31 and the mounting hole of the flange plate 51 of the end cover of the motor 6 to install the motor 6 on the positioning plate 31. A circular wire groove 33 is engraved on the periphery of the positioning hole 32 of the positioning plate 31, and the center of the circular wire groove 33 on the positioning plate 31 overlaps with the center of the mounting hole on the positioning plate 31.

[0033] When motor 6 is initially installed on positioning plate 31, the bolts and nuts are not tightened tightly. Initially, the position of motor 6 is adjusted by observing the relative position of motor 6 and circular wire slot 33 on positioning plate 31, as well as the relative position of motor 6's rotating shaft 61 and the mounting hole of positioning plate 31. The graduated rods 41 are then precisely moved so that the end blocks 42 of the graduated rods 41 in the four adjustment mechanisms all rest against the rotating shaft 61 of motor 6, and that each graduated rod 41 extends into the mounting hole of positioning plate 31 to the same length. At this point, the thumbscrews on both sides of the centering base 43 are tightened to precisely position motor 6, and the bolts and nuts securing motor 6 are then tightened.

[0034] The coupling is mounted within the support shield 7. When testing various parameters of the motor 6, one end of the motor's shaft 61 is connected to the coupling, and the torque sensor of the torque meter 8 is connected to the coupling. By precisely adjusting the motor's mounting position using the centering mechanism, the motor's shaft 61, the coupling, and the torque meter 8 are precisely aligned, enabling better testing of various parameters.

[0035] Obviously, without departing from the principles of the present invention, any improvements or modifications made should be considered within the scope of protection of the present invention.
