Because the first detecting head 32 and the second detecting assembly 04 are integrally located below, the force arm of the combined force acting point of the gravity of the first detecting head 32 and the second detecting assembly 04 acting on the first upper elastic portion 312 is larger than the force arm of the combined force acting point of the gravity of the first detecting head 32 and the gravity of the second detecting assembly 04 acting on the first lower elastic portion 314, so that the moment received by the first upper elastic portion 312 is larger than the moment received by the first lower elastic portion 314, and the deformation of the first upper elastic portion 312 is larger than that of the first lower elastic portion 314.

In some embodiments, as shown in fig. 1 and 2, the elastic coefficient of the second upper elastic portion 412 is greater than or equal to the elastic coefficient of the second lower elastic portion 414.
In this embodiment, as shown in fig. 1 and 2, two ends of the second upper elastic portion 412 are respectively disposed at first ends of the third mounting portion 411 and the fourth mounting portion 415, two ends of the second lower elastic portion 414 are respectively disposed at second ends of the third mounting portion 411 and the fourth mounting portion 415, and the second upper elastic portion 412 and the second lower elastic portion 414 may be rectangular spring pieces. Under the influence of gravity, the position of the second detecting head 42 changes from the central position of the fourth mounting portion 415 in the vertical direction to the central and lower position of the fourth mounting portion 415 in the vertical direction, so that the second upper elastic portion 412 and the second lower elastic portion 414 are in a downward bent state, the force arm of gravity of the second detecting head 42 acting on the second upper elastic portion 412 is greater than the force arm of gravity of the second detecting head 42 acting on the second lower elastic portion 414, and the deformation of the second upper elastic portion 412 is greater than the deformation of the second lower elastic portion 414.

When the second detection head 42 is in the free state, the second middle spring 413 is in the compressed state. When the second upper elastic portion 412 and the second lower elastic portion 414 are in the working state, the deformation amount is generated, and the distance between the two is shortened, at this time, the second middle elastic portion 413 can transmit acting force to the second upper elastic portion 412 and the second lower elastic portion 414, so that the deformation amounts of the second upper elastic portion 412 and the second lower elastic portion 414 are equivalent. If the second detecting head 42 is in the free state, the second middle elastic portion 413 is in the stretched state, and when the second upper elastic portion 412 and the second lower elastic portion 414 enter the working state, deformation is generated, the distance between the two parts is shortened, the second middle elastic portion 413 enters the free state after being shortened, and the acting force cannot be transmitted to the second upper elastic portion 412 and the second lower elastic portion 414, so that an error occurs in the detecting result.
In some embodiments, as shown in fig. 1 and 2, the second elastic unit 41 further includes a sensor 43; the sensor 43 is disposed near a first end of the fourth mounting portion 415.

The sensor 43 may be disposed above the fourth mounting portion 415 such that the measuring head of the sensor 43 is in contact with the top surface of the fourth mounting portion 415.

In this way, the sensor 43 can be supported, and the sensor 43 or the fixed position of the sensor 43 can be quickly replaced according to different requirements of users, so that the effects of improving the working efficiency and reducing the cost are achieved. According to the pointer or data change of the sensor 43 in the measuring process, the change amount of the distance between the first detecting head and the second detecting head can be obtained, so as to judge whether the distance between the upper groove and the lower groove of the hub bearing flange meets the clearance requirement of the double-row tapered roller bearing.
The embodiment discloses a hub bearing flange detection method applied to the hub bearing flange detection device of any of the above embodiments, as shown in fig. 4, the hub bearing flange detection method may include:
step S11, based on the completion of positioning of the hub bearing flange, the first detection head 32 and the second detection head 42 are respectively extended into an upper groove and a lower groove of the hub bearing flange;
step S12, a hub bearing flange is rotated around the center thereof to obtain a change value of the interval between the first detection head 32 and the second detection head 42;
step S13, determining that the hub bearing flange is acceptable based on the variation value of the gap between the first detection head 32 and the second detection head 42 being equal to or smaller than the gap threshold value.
In this embodiment, as shown in fig. 4, the following describes the above steps in detail:
in step S11, when the positioning of the hub bearing flange is completed, the detachable connection between the first mounting portion 311 and the guide post 12 of the base assembly 01 is released, the first detection head 32 is abutted against the lower groove of the hub bearing flange, and the detachable connection between the first mounting portion 311 and the guide post 12 of the base assembly 01 is fixed. The detachable connection of the third mounting portion 411 and the second mounting portion 315 is released, the second detection head 42 is abutted against the upper groove of the hub bearing flange, and the detachable connection of the third mounting portion 411 and the second mounting portion 315 is fixed. Therefore, the first detection head and the second detection head can be continuously contacted with the upper groove and the lower groove in the testing process, and the accuracy of measured data is ensured.
In step S12, when the hub-bearing flange is rotated around its center axis, the first and second detection heads 32, 42 can be moved up and down according to the surface conditions of the upper and lower grooves. Since the first and second detection heads 32 and 42 are parallel to each other, when the surfaces of the upper and lower grooves are flat, the distances between the first and second detection heads 32 and 42 are relatively fixed. Since the second detecting head 42 is connected to the fourth mounting portion 415 and the sensor 43 detecting head is also connected to the fourth mounting portion 415, when the interval between the upper groove and the lower groove is changed, the value of the change in the interval between the first detecting head 32 and the second detecting head 42 can be obtained by the pointer or the numerical value of the sensor 43.
In step S13, when the hub bearing flange detection operation is performed, the variation in the space between the first detection head 32 and the second detection head 42 may be caused by the unstable space between the upper groove and the lower groove, and the sensor 43 may record the variation value of the space between the first detection head 32 and the second detection head 42 during the detection operation. And when the variation value is larger than the interval threshold value, judging that the flange of the hub bearing is abnormal. And when the variation value is smaller than or equal to the spacing threshold value, judging that the hub bearing flange is qualified. In this way play of the double row tapered roller bearing can be ensured.
It will be understood by those of ordinary skill in the art that the foregoing embodiments are specific examples of implementing the disclosure, and that various changes in form and details may be made therein without departing from the spirit and scope of the disclosure.
