[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. In addition, the terms "first", "second", "third", "upper, lower, left, right", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. At the same time, in the description of the present invention, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense.

Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0018] The structure of the rotor testing machine tooling provided by the present invention is as Figure 1 and Figure 4 shown, including an equipment frame 1. A base plate 2 is fixed at the top of the equipment frame 1. A rotating mechanism 3 is arranged inside the equipment frame 1, and this rotating mechanism 3 is used to drive the rotor to rotate. The rotating mechanism 3 is composed of a motor bracket 31, a three-phase asynchronous motor 32, a bearing housing 33, a main shaft 34, and a rotor washer 35. The motor bracket 31 is fixedly connected to the surface of the base plate 2 by bolts, and the three-phase asynchronous motor 32 is fixedly connected to the surface of the motor bracket 31 by bolts. The bearing housing 33 is fixed to the surface of the base plate 2 by screws, and a rotatable main shaft 34 is fixed inside the bearing housing 33. And the bottom end of the main shaft 34 is fixedly connected to the output end of the three-phase asynchronous motor 32 through a coupling. A rotor washer 35 is sleeved on the top end of the main shaft 34, and this rotor washer 35 is used for placing the rotor to be tested.

[0019] During implementation, the rotor to be tested is sleeved onto the top of the main shaft 34 and placed on the surface of the rotor washer 35. Subsequently, the three-phase asynchronous motor 32 on the surface of the motor support 31 operates. The three-phase asynchronous motor 32 drives the main shaft 34 to rotate under the action of the bearing block 33 through the cooperation of the coupling, causing the rotor to be tested on the surface of the rotor washer 35 to rotate.

[0020] Furthermore, as Figure 1 and Figure 3 shown, a pushing mechanism 4 is connected to the surface of the bottom plate 2. The pushing mechanism 4 is composed of a cylinder 41, a carriage 42, a slide rail 43, an angle knob 44, a fixing ring 45, and a connecting rod 46. The cylinder 41 is fixedly connected to the surface of the bottom plate 2. The output end of the cylinder 41 is fixed with a carriage 42, and the sensor housing 51 is rotatably connected to the surface of the carriage 42. The bottom of the carriage 42 is slidably connected to a slide rail 43, and the bottom end of the slide rail 43 is fixedly connected to the surface of the bottom plate 2. One end of the top of the carriage 42 is fixed with a fixing ring 45, and a connecting rod 46 is rotatably connected to the inside of the fixing ring 45 through a bearing. And one end of the connecting rod 46 is fixedly connected to the surface of the rear end cover 54. A rotatable angle knob 44 is provided at one end of the fixing ring 45, and the angle knob 44 is fixed to the connecting rod 46 by a bolt.

[0021] During implementation, the cylinder 41 pulls the carriage 42 to drive the testing mechanism 5 to move to a suitable position under the sliding action of the slide rail 43. Subsequently, by rotating the angle knob 44, it drives the sensor assembly 52 in the testing mechanism 5 to rotate under the action of the fixing ring 45 in cooperation with the connecting rod 46.

[0022] Furthermore, as Figure 2 and Figure 3 shown, a testing mechanism 5 is provided on the surface of the pushing mechanism 4. The testing mechanism 5 is used for rotor testing work. The testing mechanism 5 is composed of a sensor housing 51, a sensor assembly 52, a front end cover 53, and a rear end cover 54; the rear end cover 54 is connected to the surface of the pushing mechanism 4, and a sensor assembly 52 is provided inside the rear end cover 54. The sensor assembly 52 is used for testing the rotor. One end of the sensor housing 51 is fixed with the rear end cover 54 by a bolt, and the other end of the sensor housing 51 is installed with the front end cover 53 by a screw.

[0023] During implementation, the rotor to be tested is tested by the sensor assembly 52 inside the sensor housing 51.

[0024] Furthermore, as Figure 3As shown, one end of the bottom plate 2 is further provided with a buffer assembly 6, which is used for the limit buffering work when the pushing mechanism 4 moves. The buffer assembly 6 includes a buffer bracket 61, a buffer 62 and an adjusting nut 63. The buffer bracket 61 is fixedly connected to the surface of the bottom plate 2 by bolts, and the top end of the buffer bracket 61 is connected with a penetrating buffer 62. The adjusting nut 63 is used for the limit buffering work of the carriage 42, and the adjusting nut 63 is threadedly connected to the surface of the buffer 62.

[0025] During implementation, by rotating the adjusting nut 63, the buffer 62 is adjusted along the buffer bracket 61 to a suitable position, and then the movement of the carriage 42 is limited and buffered by the action of the buffer 62.

[0026] Working principle: When in use, first, the rotor to be tested is sleeved from the top end of the main shaft 34 and placed on the surface of the rotor washer 35. Subsequently, the three-phase asynchronous motor 32 on the surface of the motor bracket 31 works. The three-phase asynchronous motor 32 drives the main shaft 34 to rotate under the action of the bearing block 33 through the cooperation of the coupling, causing the rotor to be tested on the surface of the rotor washer 35 to rotate, thus realizing the automatic rotation work of the rotor to be tested.

[0027] Subsequently, the cylinder 41 pulls the carriage 42, and under the sliding action of the slide rail 43, the test mechanism 5 is driven to move to a suitable position. Then, by rotating the angle knob 44, under the action of the fixed ring 45, the sensor assembly 52 in the test mechanism 5 is driven to rotate through the connecting rod 46. The rotor to be tested is tested by the sensor assembly 52 inside the sensor housing 51, realizing the adjustment work of the test machine tooling when testing the rotor to be tested, and improving the convenience of using the test machine tooling.

[0028] When the pushing mechanism 4 drives the test mechanism 5 to move, buffering is carried out through the buffer assembly 6. During the implementation of the buffer assembly 6, by rotating the adjusting nut 63, the buffer 62 is adjusted along the buffer bracket 61 to a suitable position, and then the movement of the carriage 42 is limited and buffered by the action of the buffer 62, thus avoiding the collision phenomenon when the test machine tooling is in use, extending the service life of the test machine tooling, and finally completing the use work of the test machine tooling.

[0029] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
