[0002] At present, the parameters of vertical motors are tested on vertical support devices, and the parameters of horizontal motors are tested on horizontal support devices. Since vertical motors and horizontal motors need to be tested on different support devices, the number of support devices and the occupied site area will increase. In addition, when changing the vertical motor to a horizontal motor for testing, the problem of whether the motor shaft and the coupling can be accurately aligned is also involved. If the alignment accuracy is not high, it will affect the accurate detection of various parameters.

[0003] Through search and inquiry, no public technology identical to the technical solution of the present invention was found, but only some related patents were found.

DETAILED DESCRIPTION

[0019] The present invention will be further described below in conjunction with embodiments and drawings: Embodiment 1

[0020] like Figure 1 and Figure 2 As shown, the horizontal detection device includes a support device, a coupling and a torque meter 8. The coupling is installed in the support protective cover 7, and the support device, the coupling and the support protective cover 7 are fixedly connected to the experimental base plate 9. One end of the coupling is connected to the torque meter 8, and the other end of the coupling is connected to the rotating shaft 61 of the motor 6, so that the vertical motor 6 can be installed on the support device in a horizontal manner to detect various parameters of the motor 6.

[0021] like Figure 3 , Figure 4 and Figure 5 As shown, the horizontal detection auxiliary support device of the vertical motor 6 includes a bracket, a positioning mechanism and a centering mechanism. Among them, the positioning mechanism includes a positioning plate 31 and a frame, and the frame includes a side plate 21. The frame in this embodiment is a "mouth" shaped structure formed by four side plates 21. The positioning plate 31 is welded and fixed on the frame, and the positioning plate 31 and the frame are connected as a whole.

[0022] A bracket is provided on each side of the frame, and the bracket includes a base 11, a support plate 12 and a reinforcement plate 13. The base 11 is provided in the horizontal direction, and the support plate 12 and the reinforcement plate 13 are provided in the vertical direction. The base 11, the support plate 12 and the reinforcement plate 13 are provided perpendicular to each other and fixedly connected together. Through mounting holes are provided on the two side plates 21 on both sides of the frame, and mounting holes corresponding to the mounting holes on the side plates 21 of the frame are provided on the support plate 12 of each bracket. Bolts pass through the mounting holes on the support plate 12 and the side plates 21 to fix the frame, the positioning plate 31 and the two brackets together.

[0023] Since the mass of the motor 6 is very large, in order to allow the entire auxiliary support device to stably support the motor 6 installed on the positioning plate 31. In this embodiment, the lengths of the base 11 and the support plate 12 are both 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, and bolts are passed through the mounting holes on the base 11 to fix the base 11 on the experimental base plate 9.

[0024] like Figures 4 to 6 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.

[0025] The positioning mechanism is installed on the bracket, and the centering mechanism is installed 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 provided 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 scales, and one end of the scale rod 41 is fixedly connected to the end block 42. Through threaded holes are provided on both sides of the centering base 43. Tightening the hand screws in the threaded holes can press the scale rod 41 to prevent the scale rod 41 from sliding in the groove of the middle base 11.

[0026] like Figures 1 to 7As shown, 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 bolt passes 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.

[0027] When the motor 6 is initially installed on the positioning plate 31, the bolts and nuts are not tightened tightly. The position of the motor 6 is initially adjusted by observing the relative position between the motor 6 and the circular wire groove 33 on the positioning plate 31, and the relative position between the motor 6 shaft 61 and the mounting hole of the positioning plate 31. Then the scale rod 41 is accurately moved so that the end blocks 42 of the scale rods 41 in the four adjustment mechanisms are all against the shaft 61 of the motor 6, and the length of each scale rod 41 extending into the mounting hole of the positioning plate 31 is the same. At this time, the hand screws on both sides of the centering base 43 are tightened to accurately position the installation of the motor 6, and then the bolts and nuts fixing the motor 6 are tightened.

[0028] That is to say, when adjusting the position of the motor 6 on the positioning mechanism so that the rotating shaft 61 of the motor 6 is aligned with the circular mounting hole on the positioning mechanism, two steps are included: the first step is to install the motor 6 on the positioning mechanism, and by observing the relative position of the rotating shaft 61 of the motor 6 and the mounting hole on the positioning mechanism, the motor 6 is moved so that the rotating shaft 61 of the motor 6 is preliminarily aligned with the mounting hole. The second step is to use the centering mechanism to accurately measure the relative position of the rotating shaft 61 of the motor 6 and the mounting hole on the positioning mechanism, and accurately adjust the position of the motor 6 on the positioning mechanism according to the measured value, so that the rotating shaft 61 of the motor is accurately aligned with the mounting hole.

[0029] The coupling is installed in the support shield 7. When the motor 6 detects various parameters, one end of the rotating shaft 61 of the motor 6 is connected to the coupling, and the torque sensor of the torque meter 8 is connected to the coupling. After the installation position of the motor 6 is accurately adjusted by the centering mechanism, the rotating shaft 61 of the motor 6 can be accurately aligned with the coupling and the torque sensor of the torque meter 8, so as to better detect various parameters.

[0030] Obviously, without departing from the principles of the present invention, several improvements or modifications made should be considered as within the protection scope of the present invention.
