Technical Field

[0001] The utility model relates to the technical field of motor shaft detection, in particular to a balance detection device for a motor shaft. Background Art

[0002] Electric motor, commonly known as "motor", refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. It is represented by the letter M (D in the old standard) in the circuit. Its main function is to generate driving torque. As a power source for electrical appliances or various machines, the generator is represented by the letter G in the circuit. Its main function is to convert electrical energy into mechanical energy.

[0003] The balance of the motor shaft has a great influence on the operation of the motor, so after the motor shaft is manufactured, the motor shaft must be balanced. According to the search, the Chinese patent document, authorization announcement number CN205691289U, discloses a motor shaft balance detection device. The device places the motor shaft between rollers, and then rotates the balance board. By observing whether the balance board rotates smoothly, it is judged whether the motor shaft is balanced. However, the rollers in the device cannot be disassembled and replaced after a period of use, and it is not convenient to move the device body, which reduces the applicability of the device body. Therefore, it is necessary to improve the existing device to meet actual needs. Utility Model Content

[0008] Preferably, the support plate is mounted on the top of the balancing platform by means of mounting screws.

[0009] Through the above technical solution, the support plate is installed on the top of the balancing platform by installing screws, so that the position of the support plate can be adjusted according to the length of the motor shaft.

[0010] Preferably, a connecting rod is installed between the supporting seat and the limiting seat, and a roller is installed on the outer wall of the connecting rod.

[0011] With the above technical solution, since the limit seat is hingedly mounted on the top of the support seat through a hinge, the limit seat can be rotated, thereby facilitating the installation and removal of the roller.

[0012] Preferably, a mounting bolt is threadedly mounted on the top end of the limiting seat.

[0013] Through the above technical solution, the limit seat can be fixed by using the mounting bolts, so that the roller can be used as a limit column.

[0014] Preferably, a rubber bump is fixedly mounted on the bottom end of the supporting base plate.

[0015] Through the above technical solution, by providing the rubber protrusions, the friction between the supporting bottom plate and the ground is increased, thereby improving the stability of the device body.

[0016] Preferably, a pulley is rotatably mounted in an array at the bottom end of the pulley box.

[0017] Through the above technical solution, by arranging the pulley, it is convenient to push the device body, thereby improving the applicability of the device body.

[0018] Compared with the prior art, the utility model provides a balance detection device for a motor shaft, which has the following beneficial effects:

[0019] 1. The utility model pushes the device body, and the device body moves to a suitable position under the action of multiple groups of pulleys, and then starts motor 2, which drives the two-way screw to rotate. The rotation of the two-way screw drives the two groups of sliders to move and gradually move away from each other, and the sliders move to both side ends, driving the top ends of the two groups of support arms to gradually move away from each other, so that the support arms drive the pulley box to move upward, and the pulley box moves upward to drive the pulley to move upward. At this time, the pulley gradually moves away from the ground, and the support bottom plate contacts the ground. Since the bottom end of the support bottom plate is equipped with a rubber bump, the stability of the device body can be increased.

[0020] 2. The utility model places two sets of support plates at appropriate positions on the top of the balancing platform according to the length of the motor shaft, and then tightens the mounting screws to fix the support plates. Then the motor shaft is placed between the rollers, and motor one is started. The motor one drives the rotating shaft to rotate, and the rotation of the rotating shaft drives the balancing platform to rotate, and the motor shaft also rotates accordingly. If the balance of the motor shaft is qualified, the balancing platform rotates smoothly. If the balance of the motor shaft is unqualified, the balancing platform rotates unsteadily, and the motor shaft slides on the roller. At the same time, when the roller needs to be replaced, it is only necessary to remove the mounting bolts, open the limit seat, remove the roller for replacement, and then close the limit seat again and screw on the mounting bolts.
