Description

Technical Field

[0001] This invention relates to the field of wheel hub dynamic balancing testing technology, specifically to an integrated wheel hub dynamic balancing testing device. Background Technology

[0002] A dynamic balancing machine is used to measure the magnitude and location of the imbalance of a rotating object. The main performance indicators of a dynamic balancing machine are the minimum achievable residual imbalance and the reduction rate of the dynamic balancing machine. The former is the minimum residual imbalance that the balancing machine can make the rotor reach, and it is an indicator of the balancing machine's highest balancing ability; the latter is the ratio of the amount of imbalance reduced after one correction to the initial amount of imbalance.

[0003] A dynamic balancing machine is a tool for inspecting wheel hubs. It is used by passing the center hole of the wheel hub through a rotating shaft, which then drives the wheel hub to rotate, thereby inspecting the wheel hub. However, in the current wheel hub inspection process, because the wheel hub itself has a certain weight, it is physically demanding for the staff to move the wheel hub continuously for installation and inspection, which is time-consuming and laborious, reducing the efficiency of the test. Summary of the Invention

The upper end of the support platform is provided with a servo motor, the drive end of the servo motor is equipped with a lead screw, and the outer end of the lead screw is connected to a slider by a thread. The slider is fixedly connected to the hub limiting block. The servo motor can drive the lead screw to rotate, and the lead screw can drive the slider to move, thereby using the slider to drive the hub to move.

[0006] Preferably, the outer end of the rotating shaft is provided with a connecting thread, and a clamping sleeve is connected to the outer end of the rotating shaft through the connecting thread. When the hub is put on the rotating shaft, the clamping sleeve can be put on the rotating shaft through the connecting thread and tightened, thereby fixing the hub through the clamping sleeve.

[0007] Preferably, a fixed rod is provided on one side of the drive motor, and a sliding sleeve is rotatably connected to the outer end of the fixed rod. The sliding sleeve is fitted onto the fixed rod to facilitate the operator to rotate the sliding sleeve.

[0008] Preferably, a connecting rod is installed at the outer end of the sliding sleeve, and a protective cover is installed at the upper end of the connecting rod. During testing, the operator can rotate the sliding sleeve to adjust the position of the protective cover, so as to cover the wheel hub with the protective cover and prevent the wheel hub from falling off accidentally during testing and causing injury to the operator.

[0009] Preferably, a display screen is provided at the outer end of the main body of the dynamic balancing machine, and a control switch is provided on one side of the display screen. The display screen can display the machine's data, and the control switch facilitates the control of the dynamic balancing machine's operation.

[0010] Compared with the prior art, the beneficial effects of the present invention are: 1. This integrated wheel hub dynamic balancing testing device allows operators to place the wheel hub inside the wheel hub limiting block during testing. A hydraulic lifting rod then drives the wheel hub upwards, aligning the center hole of the wheel hub with the rotating shaft. A servo motor is then activated, driving a lead screw to rotate. The lead screw moves a slider, which in turn moves the wheel hub, allowing it to be fitted onto the rotating shaft. While the wheel hub is on the shaft, a clamping sleeve is threaded onto the shaft and tightened, thus securing the wheel hub. Finally, the drive motor rotates the shaft to test the wheel hub. This structure saves time and effort, reduces labor consumption, improves testing efficiency, and enhances the practicality of the integrated wheel hub dynamic balancing testing device. 2. During the wheel hub dynamic balancing test, the operator can rotate the sliding sleeve to adjust the position of the protective cover, making it easy to cover the wheel hub and protect it. This prevents the wheel hub from accidentally falling off during the test and injuring the operator, thus improving safety and enhancing the protective performance of the integrated wheel hub dynamic balancing test device.
