Description

Technical Field

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

[0002] The shafted rotor is an important component in many mechanical systems, such as motors, centrifuges, pumps and compressors. However, since the rotor may be unbalanced during manufacturing, assembly and use, it will cause vibration and noise when the rotor rotates, and accelerate the wear of related components, seriously affecting the normal operation of the mechanical equipment. In order to solve this problem, a shafted rotor dynamic balancing detection device came into being. This device measures the size and position of the rotor imbalance and corrects it to eliminate the imbalance and make the rotor reach a balanced state. However, among the existing rotors, the diameters of the ends of different rotors are different. Therefore, it is necessary to adjust the position of the sensor according to the diameter of the rotor end, which is not convenient for detecting the rotor end.

[0003] Therefore, the utility model proposes a dynamic balance detection device for a shaft rotor based on the above problems. Utility Model Content

[0005] Therefore, based on the above-mentioned problem, the utility model proposes a dynamic balancing detection device for a shaft rotor, comprising a base frame, a bracket fixedly installed on the upper part of the base frame, an upper frame fixedly installed on the upper part of the bracket, a motor fixedly installed at the upper center of the upper frame, a coupling fixedly connected to the motor output shaft, and a rotor to be detected fixedly connected to the lower end of the coupling. The device is characterized in that a detection mechanism that can adapt to various rotor diameters is fixedly installed at the upper center of the base frame, and the rotor is located at the center of the detection mechanism.

[0006] Preferably: the detection mechanism includes: a turntable, a shaft block is integrally fixedly connected at the center of the base frame, the shaft block is concentric with the motor and the coupling, the outer side of the shaft block is fixedly installed on the inner side of the bearing, the outer side of the bearing is connected to the turntable, a handle is provided on the outer side of the turntable, and an arc-shaped slide rail with a shape and structure similar to a flat spiral is provided in the middle of the turntable.

[0007] Preferably: the detection mechanism also includes: a detection block, three slidable sliders are arranged on the upper part of the arc-shaped slide rail, a detection block is integrally formed on the upper part of each slider, a pressure sensor is arranged inside the detection block, a wireless module and a corresponding supporting power supply are arranged inside the pressure sensor, and the pressure sensor is wirelessly transmitted to external computers and other equipment through the wireless module.

[0008] Preferably: the detection mechanism also includes: a fixed plate, three connecting feet are fixedly welded on the upper part of the base frame, the three connecting feet are integrally fixedly connected to the fixed plate, the fixed plate is in a circular ring shape, three T-slots are arranged at the lower part of the fixed plate, and corresponding detection blocks are slidably connected inside the three T-slots.

[0009] Preferably, the points to which the three detection blocks point are concentric with the fixed disk, the rotating disk, the motor and the coupling.

[0010] Beneficial effect: When in use, the rotor is fixedly installed on the flexible coupling, and the rotor to be tested is located between the three test blocks. Then the handle is turned. The handle drives the turntable to rotate and drives the slider 301 to move toward the three T-slots 402 of the fixed disk 4, thereby performing synchronous closing and opening, thereby achieving adaptive adaptation to the diameter of the rotor end to detect dynamic balance. When the dynamic balance of the shaft rotor does not meet the standard, a large shake will occur at the bottom of the rotor, so that the three test blocks will touch the rotor before the actual value reaches the bottom of the rotor. At this time, the pressure sensor inside the test block is transmitted to the external computer to complete the test. BRIEF DESCRIPTION OF THE DRAWINGS
