Description

Technical Field

[0001] The invention relates to the technical field of automobile maintenance equipment, and in particular to an external surface radian detection device for wheel maintenance and a use method thereof. Background Art

[0002] The wheel hub is the part of the wheel center where the axle is installed, which is also commonly known as the "wheel rim" or "steel rim". The wheel hub is easily stained with dirt. If it is not cleaned for a long time, it may be corroded and deformed, resulting in safety hazards. Therefore, special attention should be paid to the maintenance of the wheel hub. The wheel hub is one of the important components of the car wheel. After the car has been used for a long time or after a traffic accident, the wheel hub that has not been scrapped usually needs to be inspected and corrected by a maintenance technician to prevent the wheel hub from losing roundness, which may cause certain driving risks.

[0003] The existing operation method is that maintenance workers usually judge by eyes. After the judgment is completed, the wheel hub is installed on a dynamic balancing instrument and dynamic detection is carried out to check whether the wheel hub is out of round. If it is out of round, the wheel hub needs to be removed from the dynamic balancing instrument and then adjusted. After the adjustment is completed, dynamic detection is carried out again. This reciprocating process wastes a lot of work time. Therefore, for technicians in this field, how to directly measure whether the wheel hub is out of round through a simple technical solution has become an urgent problem to be solved.

[0011] A method for using an external surface curvature detection device for wheel maintenance, the method comprising the following steps:

[0012] The first step is to put the wheel hub to be tested, connect the electronic components of the device to an external power supply, turn the first adjustment knob, move the radius adjustment tube and the detection rod as far away from the arc center of the first semicircular skeleton as possible, and put the wheel hub to be tested between the first semicircular skeleton and the second semicircular skeleton, and the center of the wheel hub must coincide with the arc center of the first semicircular skeleton;

[0013] The second step is debugging. Turn the first adjustment knob to drive the detection rod to move toward the wheel hub. When the detection wheel touches the detection position of the wheel hub, stop turning the first adjustment knob, and then turn the second adjustment knob to move the pressure sensor to fit the feedback contact. When the pressure sensor fits the feedback contact, turn the second adjustment knob and keep the light module just off. At this time, record the scale according to the triangular groove.

[0014] The third step is testing. The user holds the handles and rotates the two handles along the arc-shaped slide rail. At this time, the detection wheel rotates along the hub. When the hub is not a perfect circle, as the detection wheel rolls, the hub will press the detection wheel, and then the detection wheel will shift. The feedback contact at the other end of the detection rod will squeeze the pressure sensor. The pressure sensor converts the pressure signal into an electrical signal and transmits it to the control module inside the lamp module, causing the lamp module to light up. At the same time, the feedback rod moves toward the side of the threaded rod. If the hub is a perfect circle, there will be no reaction.

[0015] Step 4: The test is completed. When the wheel hub is not a perfect circle, as the feedback rod shifts, the degree of the feedback rod surface will also shift. Record the corresponding scale to obtain the wheel hub arc deformation data.

[0016] The fifth step is to take the average value of multiple measurements. After the test is completed, rotate the wheel hub and place it into the device. Repeat the above steps to complete multiple tests, and record the scales of multiple tests to calculate the average value. The angle range of the rotating wheel hub is between 30°-45°.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention can simply detect whether the wheel hub is out of round by directly placing the wheel hub in the device without complicated installation steps, thereby solving the problem of frequent installation of the wheel hub caused by the need to use a dynamic balancer for detection in the existing detection method, and has high detection efficiency, simplicity and convenience;

[0019] When detecting an out-of-round wheel hub, the present invention can feed back out-of-round data to a user, thereby assisting the user in repairing the wheel hub, thus solving the problem of blind repair in the absence of data in existing repair methods. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] This embodiment also provides a method for using the device for detecting the curvature of the outer surface of a wheel for repairing. The steps of the method are as follows:

[0035] The first step is to put the wheel hub to be tested, connect the electronic components of the device to an external power supply, turn the first adjustment knob 603, move the radius adjustment cylinder 602 and the detection rod 606 as far away from the arc center of the first semicircular skeleton 1 as possible, and put the wheel hub to be tested between the first semicircular skeleton 1 and the second semicircular skeleton 2, and the center of the wheel hub must coincide with the arc center of the first semicircular skeleton 1;

[0036] The second step is debugging. Turn the first adjusting knob 603 to drive the detection rod 606 to move toward the hub. When the detection wheel 609 touches the hub detection position, stop turning the first adjusting knob 603, and then turn the second adjusting knob 618.

When the hub is not a perfect circle, as the detection wheel 609 rolls, the hub will press the detection wheel 609, and then the detection wheel 609 will deviate. The feedback contact 610 at the other end of the detection rod 606 will squeeze the pressure sensor 617. The pressure sensor 617 converts the pressure signal into an electrical signal and transmits it to the control module inside the lamp module 8, causing the lamp module 8 to light up. At the same time, the feedback rod 616 moves toward the side of the threaded rod 614. If the hub is a perfect circle, there will be no reaction.

[0038] Step 4: The detection is completed. When the wheel hub is not a perfect circle, as the feedback rod 616 is offset, the degree of the surface of the feedback rod 616 will also be offset. The corresponding scale is recorded to obtain the wheel hub arc deformation data.

[0039] The fifth step is to take the average value of multiple measurements. After the test is completed, rotate the wheel hub and place it into the device. Repeat the above steps to complete multiple tests, and record the scales of multiple tests to calculate the average value. The angle range of the rotating wheel hub is between 30°-45°.
