Description

Technical Field

[0001] The utility model generally relates to the technical field of automobile detection, and in particular to a special detection device for automobile wheel hub. Background Art

[0002] In order to ensure vehicle safety and performance, automobile wheels need to be inspected after production and maintenance. The main inspection contents include wheel diameter, whether the wheel rim and center hole are coaxial, etc. In the manufacturing enterprise, special measuring equipment can be used to measure the wheels off the production line. However, for some wheels that have structural damage during driving, they need to be repaired by the repair shop. The measuring equipment in the repair shop is simple and the measurement accuracy is not high. Utility Model Content

[0003] In view of the above problems, the present application provides a special detection device for automobile wheel hub, which is used to at least partially solve the technical problems existing in the prior art.

[0004] The utility model provides a special detection device for automobile wheel hub, comprising:

[0005] The frame includes a vertically arranged stand;

[0006] A fixing assembly, used for fixing the wheel rim, comprising a rotating shaft rotatably arranged on the vertical plate and a locking nut threadedly connected to a side of the rotating shaft away from the vertical plate, wherein a first conical surface facing the locking nut is coaxially arranged on the rotating shaft, and a second conical surface facing the first conical surface is arranged on the locking nut;

[0007] A driving device, used for driving the rotating shaft to rotate around its axis;

[0008] The detection component includes a second shaft arranged parallel to the rotating shaft and spaced apart from the rotating shaft, a swing arm arranged on the second shaft, a detection sensor for detecting the deflection angle of the second shaft, and an elastic member for driving the end of the swing arm to rotate toward the rotating shaft.

[0009] Specifically, through the above-mentioned setting method, it is possible to detect whether the rim of the wheel hub is coaxial with the center hole. During the detection, the center hole of the wheel hub is sleeved on the periphery of the rotating shaft, locked with the wheel hub by a locking nut, and the center hole of the wheel hub is positioned by the first conical surface and the second conical surface, so that the center hole is coaxial with the first axis. Then, the swing arm is deflected under the elastic force of the elastic member, so that the end of the swing arm away from the rotating shaft contacts the position of the rim that needs to be inspected after repair. Then, the rotating shaft is driven to rotate around the axis by a driving device, so that the ends of the swing arm pass through the surface of the rim in turn. When the position of the rim to be detected is deformed, it will be not coaxial with the center hole, so that the swing arm will be deflected, driving the second axis to deflect. At this time, the deflection angle of the second axis is detected by the detection sensor, thereby achieving the purpose of detecting the rim.

[0010] Furthermore, a roller is rotatably provided at one end of the swing arm away from the second axis, and a central axis of the roller is arranged parallel to the second axis.

[0011] Specifically, by arranging a roller at the end of the swing arm, the wheel surface of the roller can contact the position of the wheel hub to be detected, so that the sliding friction is converted into rolling friction. On the one hand, the wear amount can be reduced, and on the other hand, the diameter of the rim can be detected by detecting the number of rolling circles of the roller.

[0012] Furthermore, the second shaft is rotatably arranged on the frame, the elastic member is a torsion spring arranged between the second shaft and the frame, and the swing arm is non-rotatably matched with the second shaft.

[0013] Furthermore, the driving device is a driving motor.

[0014] Furthermore, an adjusting member is also provided on the frame, and the adjusting member can slide in a direction parallel to the axis of the rotating shaft, and the second shaft is rotatably provided on the sliding member.

[0015] Specifically, by setting an adjusting member, the position of the second shaft can be adjusted by sliding the adjusting member, thereby achieving the purpose of adjusting the position of the swing arm. By adjusting the position of the swing arm, different positions of the wheel hub can be measured, thereby improving the detection effect.

[0016] Furthermore, a positioning plate is coaxially arranged at one end of the second shaft, a locking rod is threadedly connected to the adjusting member, the locking rod is parallel to the second shaft and eccentrically arranged, and a positioning hole corresponding to the locking rod is arranged on the positioning plate.

[0017] Specifically, by providing a positioning plate at the end of the second shaft and providing a locking rod on the adjusting member, and by determining the position of the positioning hole, the end of the swing arm can be located away from the rotating shaft when the locking rod extends into the positioning hole, so that the second shaft can be locked, thereby facilitating the removal and installation of the wheel hub from the rotating shaft.

[0018] Furthermore, a guide member and a driving screw are arranged in parallel on the frame, and the adjusting member includes a sliding member that slides with the guide member and a screw nut threadedly connected to the driving screw, the screw nut is connected to the sliding member, and the second shaft is arranged on the screw nut.

[0019] Furthermore, it also includes a second detection sensor disposed on the frame for detecting the rotation angle of the rotating shaft and a third detection sensor for detecting the rotation angle of the roller.

[0020] Specifically, by setting up a second detection sensor and a third detection sensor, the rotation angle of the rotating shaft and the rotation angle of the roller can be detected. When measuring the outer diameter of the wheel hub, the rotating shaft is driven to rotate by the driving device, and the second detection sensor and the third detection sensor start detection at the same time. The rotation angle of the rotating shaft and the rotation angle of the roller detected by the second detection sensor are obtained, so that the circumference of the position to be detected can be obtained, and the diameter can be obtained, thereby achieving the purpose of detecting the diameter.

[0036] Specifically, through the above-mentioned setting method, it is possible to detect whether the rim of the wheel hub 9 is coaxial with the center hole. During the detection, the center hole of the wheel hub is sleeved on the periphery of the rotating shaft 21, and the wheel hub is locked by the locking nut 22. The center hole of the wheel hub is positioned by the first conical surface and the second conical surface, so that the center hole is coaxial with the first axis. Then, under the elastic force of the elastic member, the swing arm 32 is deflected, so that the end of the swing arm away from the rotating shaft 21 contacts the position of the rim that needs to be inspected after repair. Then, the rotating shaft 21 is driven to rotate around the axis by the driving device 4, so that the end of the swing arm passes through the rim in sequence. When the surface of the wheel rim is deformed at the position to be detected, it will be out of coaxiality with the center hole, so the swing arm will be deflected, driving the second axis 31 to deflect. At this time, the detection sensor 33 is used to detect the deflection angle of the second axis 31, so as to achieve the purpose of detecting the wheel rim. It should be noted that the detection sensor 33 can be a sensor used in the prior art for detecting the rotation angle of a rotating part, such as a rotation angle sensor, an encoder, etc. This technology is commonly used in the prior art, and its principle will not be repeated here.

Figure 3 At this time, the state of the swing arm is that the swing arm is away from the rotating shaft. At this time, the locking rod 311 can extend into the positioning hole to lock the second shaft, thereby facilitating the removal and installation of the wheel hub from the rotating shaft.
