Specific embodiments

[0023] Next, the technical solutions in the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the present utility model. In addition, the forms of each structure described in the following embodiments are merely examples, and the present utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0024] Referring to Figures 1 - 5 , the present utility model provides a balancing wheel hub calibration device, including a housing 1, a support rod 3, and a display 4. Two groups of L-shaped plates 14 are fixedly connected to the outer wall of the top of the housing 1 by bolts, and each group has two. A vibration telecommunication sensor 15 is provided on one side of the L-shaped plate 14, and the vibration telecommunication sensor 15 is electrically connected to the display 4. A square plate 6 is fixedly connected between the inner walls on both sides of the housing 1 by bolts. A motor is fixedly connected to one side of the square plate 6 by bolts. One end of the output shaft of the motor passes through the upper surface of the square plate 6 and is key-connected to a main shaft 7. The top end of the main shaft 7 passes through the outer wall of the top of the housing 1 and is rotatably connected to the housing 1. A driving pulley 8 is provided on the circumferential outer wall of the main shaft 7. The outer wall of the top of the housing 1 is rotatably connected to an auxiliary shaft 9. The bottom end of the auxiliary shaft 9 passes through the inner wall of the top of the housing 1 and extends into the housing 1. A driven pulley 10 is provided on the circumferential outer wall of the part of the auxiliary shaft 9 extending into the housing 1, and the driven pulley 10 is connected to the driving pulley 8 by a belt drive. The top ends of the main shaft 7 and the auxiliary shaft 9 are both fixedly connected to a turntable 5 by bolts. A round rod 12 matching the balancing wheel hub body is provided on the turntable 5, and a disassembly component is provided between the round rod 12 and the turntable 5. And a locking component for fixing the balancing wheel hub body is provided at the top end of the round rod 12. By providing the driving pulley 8 and the driven pulley 10, the dynamic balance of two balancing wheel hub bodies can be detected simultaneously, without detecting one by one, saving the time used for detection and greatly increasing the working efficiency of the device.

[0025] Among them, the disassembly component is a threaded groove, which is opened on the upper surface of the turntable 5. A threaded column 11 is welded to the bottom end of the round rod 12, and the threaded column 11 is threadedly connected in the threaded groove. The round rod 12 can be disassembled and replaced through the provided disassembly component. When the inner diameters of the balance wheel hubs to be measured are different, the round rod 12 suitable for the diameter of the balance wheel hub can be replaced. The structure is simple and the operation is convenient. The locking component is a threaded rod 16, which is welded to the top end of the round rod 12. A knob 17 is threadedly connected to the circumferential outer wall of the threaded rod 16, and a ring 18 is welded to the lower surface of the knob 17. Through the provided locking component, after the balance wheel hub is inserted onto the round rod 12, the balance wheel hub can be fixed to prevent the balance wheel hub from being thrown off during the dynamic balance test, thus eliminating potential safety hazards. A limiting plate 13 is fixedly connected to the circumferential outer wall of the round rod 12 by bolts, and the limiting plate 13 is arranged at a position close to the bottom of the round rod 12. Through the provided limiting plate 13, the balance wheel hub can be limited during installation to prevent it from contacting the turntable 5 and damaging the balance wheel hub. Rubber pads 19 are provided on the upper surface of the limiting plate 13 and the lower surface of the ring 18, and the rubber pads 19 can protect the balance wheel hub during fixation to avoid damage. The inner diameter of the ring 18 is slightly larger than the diameter of the round rod 12, which can prevent the inner wall of the ring 18 from contacting the round rod 12 during locking, resulting in the bottom of the ring 18 being unable to contact the balance wheel hub, thus preventing it from being locked and fixed. Fixing plates 2 are fixedly connected to both sides of the housing 1 by bolts, and two mounting holes are symmetrically opened on each of the two fixing plates 2. Through the provided fixing plates 2 and mounting holes, the device can be fixed to prevent the device from vibrating during the test, resulting in test errors. Wedge-shaped blocks are fixedly connected to both sides of the motor by bolts, and one side of each of the two wedge-shaped blocks is fixed to the lower surface of the square plate 6. Through the provided wedge-shaped blocks, the motor can be further fixed to increase the stability of the motor.

[0026] The present utility model is used in the following steps:

[0027] S1: When it is necessary to detect the balance wheel hub, first find the round rod 12 that matches its inner diameter, thread the threaded column 11 at the bottom of the round rod 12 into the threaded groove, then rotate the knob 17 to remove it. Then, align the inner holes on the two balance wheel hubs with the threaded rod 16 and insert them onto the round rod 12 until their lower surfaces contact the limiting plate 13. Then install the knob 17 and rotate the knob 17 to move it towards the balance wheel hub until the lower surface of the ring 18 contacts its upper surface, and then it can be locked and fixed.

[0028] S2: Then start the motor. The rotation of the output shaft of the motor drives the main shaft 7 to rotate and at the same time drives the driving pulley 8 to rotate. Since the driving pulley 8 and the driven pulley 10 are driven by a belt, when the driving pulley 8 rotates, it will drive the driven pulley 10 to rotate together, thereby driving the auxiliary shaft 9 to rotate. The rotation of the main shaft 7 and the auxiliary shaft 9 drives the turntable 5 to rotate. The rotation of the turntable 5 drives the round rod 12 to rotate, and then drives the balance wheel hub body locked and fixed on it to rotate;

[0029] S3: When the balance wheel hub body rotates, the vibration telemetry sensor 15 performs dynamic balance detection on it, and at the same time the detected data is transmitted to the display 4, and the detection process can be seen in real time.

[0030] Finally, several points should be noted: In the description of the present application, it should be noted that unless otherwise specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, which can be mechanical connection or electrical connection, or the communication inside two components, and can be directly connected. "Up", "down", "left", "right", etc. are only used to represent the relative position relationship. When the absolute position of the object being described changes, the relative position relationship may change;
