[0006] After the measuring pieces are assembled, make the bottom of the measuring piece flush with the outer surface of the mounting shaft. Then, make the bottom of the measuring piece rub against the outer surface of the shaft to be measured. Making the bottom of the measuring piece flush with the outer surface of the mounting shaft makes it easier to determine the diameter of the mounting shaft. When the bottom of the measuring piece rubs against the outer surface of the shaft to be measured, it makes it easier to determine that the mounting shaft and the shaft to be measured have the same diameter, thus ensuring the concentricity of the mounting shaft and the shaft to be measured.

Obviously, the described embodiment is a part of the embodiment of the utility model, rather than all the embodiment. Based on the described embodiment of the utility model, all other embodiments obtained by the ordinary skill in the art belong to the scope of the utility model protection.

[0021] As Figure 1 , 2 , 4 shows:

[0022] The embodiment provides a kind of measuring tool for adjusting the concentricity of motor encoder, including connecting piece 1, connecting piece 1 is made of two flange plates 1.1, two flange plates 1.1 are arranged in parallel, one side of flange plate 1.1 is detection surface 3, detection surface 3 is used to connect measuring part 5, and measuring part 5 is used to detect the shaft to be detected;The other side is installation surface 2, connecting piece 1 is connected with installation shaft end by installation surface 2, installation surface 2 is used to connect installation shaft, and installation surface 2 is equipped with threaded hole 1.2 in communication with installation shaft, fastening bolt is arranged in threaded hole 1.2, and installation surface 2 is fixed on installation shaft by fastening bolt.Here, installation shaft can be the rear end part of motor, and can also be the shaft of encoder.

[0023] As Figure 1 , 4 shows:

[0024] The connecting piece 1 is a flange plate 1.1 which is connected with the mounting shaft through fasteners, and a connecting block 4 is arranged on the flange plate 1.1, the connecting block 4 is in L shape, the connecting block 4 is arranged on the detection surface 3 of the flange plate 1.1 and extends outward, and a measuring part 5 is arranged at one end of the connecting block 4, which is used to facilitate contact with the to-be-detected shaft, so as to realize detection of the concentricity of the mounting shaft and the to-be-detected shaft. The measuring part 5 is composed of a plurality of measuring pieces which are connected in the same shape, one side of each measuring piece is provided with a groove 5.2, and the other side is provided with a convex 5.3. In the actual assembly process, the convex 5.3 of the lower measuring piece is inserted into the groove 5.2 of the upper measuring piece, so as to complete the splicing work of the measuring piece. This splicing method not only ensures the tightness of the connection between the measuring pieces, but also ensures the stability of the overall structure during the measurement.

[0025] As shown in Figure 1 , 2 , 3:

[0026] When the splicing of the measuring piece is completed, the bottom of the measuring piece is in the same plane as the outer surface of the mounting shaft, which can conveniently determine the diameter of the mounting shaft, and the place where the bottom of the measuring piece contacts is the same as the diameter of the mounting shaft;

[0027] As shown in Figure 2 , 4 : 4:

[0028] Further, the bottom of the measuring piece is in contact with the outer surface of the to-be-detected shaft, at this time, if the bottom of the measuring piece is in good contact with the outer surface of the to-be-detected shaft, it can be determined that the mounting shaft and the to-be-detected shaft are the same diameter, which ensures that the mounting shaft and the to-be-detected shaft are the same diameter and concentric, so as to ensure that the mechanical device works stably and efficiently during operation, and reduces the problems of vibration and wear caused by different concentricity.

[0029] As shown in Figure 1 , 3 , 4:

[0030] The measuring block 5.1 is provided with a convex block 5.3 on one side and a recess 5.2 on the other side. The convex block 5.3 is clamped in the recess 5.2 to complete the splicing of the measuring block 5.1. In order to ensure the stable installation of the connecting block 4 on the flange plate 1.1, the flange plate 1.1 is provided with a threaded hole 1.2, and the other end of the connecting block 4 is provided with an external thread. The external thread of the connecting block 4 is rotatably installed in the threaded hole 1.2 of the flange plate 1.1, and a nut 1.3 is further arranged on the external thread. The nut 1.3 is tightly screwed on the external thread of the connecting block 4 to firmly fix the connecting block 4 on the flange plate 1.1. In this way, in the case of rotation of the flange plate 1.1, the connecting block 4 can be effectively prevented from rotating in the threaded hole 1.2, avoiding the deviation of the connecting block 4. Once the connecting block 4 deviates, the concentricity of the installation shaft and the shaft to be measured cannot be accurately detected, which affects the performance and operation stability of the entire mechanical device.

[0031] As shown in Figure 2 、 3 , 4:

[0032] At the rear end of the motor, an installation bracket 6 is arranged. The installation bracket 6 provides a special installation position for connecting the encoder and can support and fix the encoder. Through the connection and support of the installation bracket 6, the encoder can be stably connected with the rear end of the motor, ensuring that the encoder can accurately obtain the running data of the motor, such as speed, angle and other information, during the operation of the motor, providing reliable data support for the entire control system, and realizing accurate monitoring and control of the running state of the motor.

[0033] Working principle: In use, the mounting surface 2 of the flange plate 1.1 is fixed with the installation shaft (the rear end of the motor or the output end of the encoder) through bolts, and then the connecting block 4 is installed in the threaded hole 1.2 on the flange plate 1.1 and the nut 1.3 is fixed on the connecting block 4 to prevent the connecting block 4 from rotating in the threaded hole 1.2 when the installation shaft rotates, so that the measuring part 5 arranged on the connecting block 4 deviates. After fixing the connecting block 4, the number of measuring blocks 5.1 is adjusted to make the bottom of the measuring block 5.1 in line with the outer surface of the installation shaft, and then the detachable parts are installed. If the bottom of the measuring block 5.1 is in contact with the outer surface of the shaft to be measured, it indicates that the installation shaft and the shaft to be measured are concentrically arranged. If they are not concentric, the position of the installation shaft or the shaft to be measured can be adjusted to make the installation shaft and the shaft to be measured concentrically arranged.

[0034] In addition, it needs to be explained that, in the description of the present application, unless otherwise specified and limited, the terms "mounting", "connecting", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or the communication inside two elements.
