[0055] like Figure 1-Figure 4 As shown, the steering wheel assembly 1 includes a steering wheel 11 and a brake disc 12. The brake disc 12 and the steering wheel 11 are coaxially arranged and detachably connected. A first bearing 110 is detachably provided at the center of the steering wheel 11, and a second bearing 120 is detachably provided at the center of the brake disc 12. Specifically, the steering wheel 11 has a metal hub and a rubber wheel sleeved on the metal hub. The metal hub is provided with six through holes for bolts to pass through, and the brake disc 12 is provided with six threaded holes corresponding to the through holes. The six bolts pass through the two through holes in turn and are threadedly connected in the six threaded holes, so that the steering wheel 11 and the brake disc 12 are detachably connected. When the steering wheel 11 and the brake disc 12 need to be disassembled, it is only necessary to unscrew the six bolts respectively, and the disassembly and assembly are simple.

[0056] like Figure 5-Figure 7As shown, a detection device for a steering wheel assembly 1 of this embodiment mainly includes: a mounting seat 2, a clamping module 3, a driving module 4, a flatness detection meter 5, a push screw 6 and a speed detection meter 7. Among them, the clamping module 3 mainly includes: a first clamping shaft 31 and a second clamping shaft 32. The driving module 4 mainly includes: a first motor 41, a second motor 42, a motor seat 43 and a driving wheel 44.

[0057] The mounting base 2 includes a first mounting plate 21 and a second mounting plate 22 which are spaced apart from each other. The first mounting plate 21 and the second mounting plate 22 are arranged in parallel and fixedly connected by a bottom plate which is perpendicular to the first mounting plate 21 and the vertical plate, and a plurality of reinforcing ribs are arranged between the first mounting plate 21 and the vertical plate, and between the second mounting plate 22 and the vertical plate, to ensure the overall strength of the mounting base 2.

[0058] The clamping module 3 is used to clamp the steering wheel assembly 1. The clamping module 3 includes a first clamping shaft 31 and a second clamping shaft 32 which are coaxially arranged. The first clamping shaft 31 and the second clamping shaft 32 are respectively arranged on the first mounting plate 21 and the second mounting plate 22. Both the first clamping shaft 31 and the second clamping shaft 32 have a clamping protrusion 312, which is a clamping ring and is located on the outer periphery of the first clamping shaft 31 and the second clamping shaft 32. One of the first clamping shaft 31 and the second clamping shaft 32 can move telescopically so that the first clamping shaft 31 and the second clamping shaft 32 can clamp or loosen the steering wheel assembly 1. Specifically, this embodiment illustrates the situation where the first clamping shaft 31 can move telescopically, that is, the first clamping shaft 31 is a screw rod, and a second nut structure 26 is provided on the first mounting plate 21. The first clamping shaft 31 is inserted into the second nut structure 26 to form a screw rod nut structure, so that the first clamping shaft 31 can move telescopically. A second rotating hand wheel 310 is provided at one end of the first clamping shaft 31 to facilitate the rotation of the first clamping shaft 31 and control its telescopic movement. When the first clamping shaft 31 is telescopically adjusted to the desired position, the position of the first clamping shaft 31 can be locked by locking the second rotating hand wheel 310. When the first clamping shaft 31 approaches the second clamping shaft 32, the steering wheel assembly 1 can be clamped to ensure that the rotating wheel assembly will not shake after being clamped and positioned, and the structural stability is good. When the first clamping shaft 31 moves away from the second clamping shaft 32, the steering wheel assembly 1 can be loosened. When the clamping module 3 clamps the steering wheel assembly 1: the first clamping shaft 31 penetrates into the first bearing 110, and the clamping protrusion 312 on the first clamping shaft 31 presses against the side of the first bearing 110; the second clamping shaft 32 penetrates into the second bearing 120, and the clamping protrusion 312 on the second clamping shaft 32 presses against the side of the second bearing 120; the steering wheel 11 and the brake disc 12 can both rotate around the first clamping shaft 31 and the second clamping shaft 32.

[0059] It should be explained that when the first clamping shaft 31 and the second clamping shaft 32 clamp the steering wheel assembly 1 to position, the steering wheel assembly 1 can rotate around the center of the first clamping shaft 31 and the second clamping shaft 32. In the process of clamping the steering wheel assembly 1, the second clamping shaft 32 is first inserted into the inner ring of the second bearing 120 at the center of the brake disc 12, and then the second rotating hand wheel 310 is rotated to make the first clamping shaft 31 move in the direction close to the second clamping shaft 32, so that the first clamping shaft 31 is inserted into the inner ring of the first bearing 110 at the center of the steering wheel 11. When the clamping protrusion 312 on the first clamping shaft 31 is pressed against the inner ring side of the first bearing 110, and the clamping protrusion 312 on the second clamping shaft 32 is pressed against the inner ring side of the second bearing 120, the steering wheel assembly 1 is clamped and positioned by the clamping module 3. Otherwise, the steering wheel assembly 1 can be removed from the clamping module 3.

[0060] The driving module 4 includes a first motor 41, a second motor 42, a motor seat 43 and a driving wheel 44. The first motor 41 is fixedly mounted on the motor seat 43, and the driving wheel 44 is arranged on the output shaft of the first motor 41. When the first motor 41 rotates, the driving wheel 44 can be driven to rotate. The motor seat 43 is movably arranged on the mounting seat 2, and the second motor 42 is arranged on the mounting seat 2, and can drive the motor seat 43 to move. Specifically, a guide rail 210 is arranged on the mounting seat 2, and a second slide groove 430 is arranged on the motor seat 43. The guide rail 210 is inserted into the second slide groove 430. The second slide groove 430 is a dovetail groove arranged in the vertical direction. The guide rail 210 matches the dovetail groove to ensure that the mounting seat 2 slides up and down along the groove and will not detach from the mounting seat 2. The second motor 42 is a screw motor, and a nut matching it is arranged on the motor seat 43. The screw of the screw motor cooperates with the nut on the motor seat 43 to form a screw nut mechanism. The screw motor drives the motor seat 43 to move up and down, thereby driving the first motor 41 and the driving wheel 44 to move up and down. That is, after the clamping module 3 clamps the steering wheel assembly 1, the second motor 42 can drive the motor seat 43 to move, so that the driving wheel 44 contacts or separates from the steering wheel 11; when the driving wheel 44 contacts the rotating wheel, the driving wheel 44 can drive the steering wheel 11 through friction. In actual use, the second motor 42 drives the telescopic movement of the motor seat 43 to drive the lifting and lowering movement of the first motor 41 and the driving wheel 44, so that the contact and separation of the rotating wheel and the steering wheel assembly 1 can be achieved, that is, the steering wheel 11 can be rotated by the friction of the driving wheel 44 from a stationary state, or it can gradually become stationary from a rotating state (the driving wheel 44 is separated from the steering wheel assembly 1).

[0061] The flatness detection gauge 5 is arranged on the second mounting plate 22 and is used to detect the flatness of the brake disc 12. Specifically, the second mounting plate 22 is provided with a first slide groove 220 arranged in the transverse direction, and the flatness detection gauge 5 can be slidably inserted into the first slide groove 220. Since the brake disc 12 needs to rotate at a high speed during the detection process, the flatness detection gauge 5 in this embodiment can be slidably adjusted along the first slide groove 220 arranged in the transverse direction, that is, adjusted along the radial direction of the brake disc 12, which can ensure that the flatness detection gauge 5 can comprehensively detect the flatness of the outer side of the brake disc 12 and ensure the accuracy of the detection result. A laser speed detection gauge 7 is also provided on the mounting seat 2. The speed detection gauge 7 is used to measure the speed of the steering wheel assembly 1, that is, in the actual detection process, the detection can be performed when the rotation speed of the steering wheel assembly 1 reaches a certain value.

[0062] like Figure 7-Figure 11 As shown, in the detection device of this embodiment, the mounting seat 2 is provided with a first positioning structure 23 and a second positioning structure 24, the first positioning structure 23 can position the steering wheel 11, and the second positioning structure 24 can position the brake disc 12. The mounting seat 2 is provided with a push screw 6, when the steering wheel 11 is positioned on the first positioning structure 23, the push screw 6 can push the first bearing 110 out of the steering wheel 11; when the brake disc 12 is positioned on the second positioning structure 24, the push screw 6 can push the second bearing 120 out of the brake disc 12. Further, the second positioning structure 24 includes a forward card slot 241 and a reverse card slot 242 which are symmetrically arranged, and the forward card slot 241 and the reverse card slot 242 can respectively position the brake disc 12 in the forward direction and in the reverse direction, so as to facilitate pushing the second bearing 120 out of the brake disc 12 and installing the second bearing 120 into the brake disc 12. The steering wheel 11 can be positioned on the first positioning structure 23 in the forward and reverse directions, respectively, so as to facilitate pushing the first bearing 110 out of the steering wheel 11 and installing the first bearing 110 into the steering wheel 11. A push plate 61 is provided at one end of the push screw 6, a first rotating hand wheel 62 is provided at the other end of the push screw 6, and a first nut structure 25 matched with the push screw 6 is provided on the mounting seat 2, and the push screw 6 and the first nut structure 25 cooperate to form a screw nut mechanism. During actual use, the first positioning structure 23 on the mounting seat 2 of this embodiment can position the steering wheel 11 in the forward and reverse directions respectively, and the second positioning structure 24 on the mounting seat 2 can position the brake disc 12 in the forward and reverse directions respectively, and a push screw 6 is provided on the mounting seat 2, which facilitates the removal of the first bearing 110 from the steering wheel 11 and the transfer of the first bearing 110 into the steering wheel 11, and the removal of the second bearing 120 from the brake disc 12 and the transfer of the second bearing 120 into the brake disc 12. It is easy to use and can effectively ensure the detection efficiency of the detection device.

[0063] In the detection device of this embodiment, a standard steering wheel and a standard brake disc are also configured. The standard steering wheel can be assembled with the brake disc 12 to form the steering wheel assembly 1, and the standard brake disc can be assembled with the steering wheel 11 to form the steering wheel assembly 1. It should be explained that the assembly of the standard steering wheel and the standard brake disc is a qualified steering wheel assembly 1, and its tolerance can be ignored. When the detection device detects that the steering wheel assembly 1 is beyond the allowable tolerance range, by configuring the standard steering wheel and the standard brake disc, it can be conveniently traced whether the first bearing 110 or the second bearing 120 needs to be replaced.

[0064] In actual use, the first clamping shaft 31 and the second clamping shaft 32 in the clamping module 3 of this embodiment respectively penetrate the first bearing 110 and the second bearing 120 from both sides, and the clamping protrusions 312 on the two respectively press against the side of the first bearing 110 and the side of the second bearing 120 to clamp and position the steering wheel assembly 1. The second motor 42 drives the motor seat 43 to move, so that the driving wheel 44 on the first motor 41 contacts the steering wheel 11 on the steering wheel assembly 1, and the first motor 41 drives the driving wheel 44 to rotate, so that the steering wheel assembly 1 can be driven to rotate by friction. By obtaining the flatness value detected by the flatness detection table 5, it can be determined whether the steering wheel 11 assembly is qualified. If the detected flatness value is within the allowable tolerance range, the steering wheel assembly 1 is qualified, that is, the first bearing 110 and the second bearing 120 are qualified. If it exceeds the allowable tolerance range, the steering wheel assembly 1 is disassembled into two parts, the steering wheel 11 and the brake disc 12, and then the disassembled steering wheel 11 is assembled with the standard brake disc, and the disassembled brake disc 12 is assembled with the standard steering wheel. After testing them separately, it can be detected whether the first bearing 110 or the second bearing 120 is unqualified.

[0065] In summary, the present embodiment provides a detection method for a steering wheel assembly 1, which is applied to the above-mentioned detection device. The detection method for the steering wheel assembly 1 includes:

[0066] First, clamp the steering wheel assembly 1 on the clamping module 3, wherein the first clamping shaft 31 penetrates into the first bearing 110, and the clamping protrusion 312 on the first clamping shaft 31 presses against the side of the first bearing 110, and the second clamping shaft 32 penetrates into the second bearing 120, and the clamping protrusion 312 on the second clamping shaft 32 presses against the side of the second bearing 120.

[0067] The second motor 42 drives the motor seat 43 to slide, so that the driving wheel 44 on the first motor 41 contacts the steering wheel on the steering wheel assembly 1; the first motor 41 drives the driving wheel 44 to rotate, and the driving wheel 44 friction drives the rotating wheel assembly to rotate, so that the rotation speed of the rotating wheel assembly reaches a preset value (the specific rotation speed can be measured by the laser rotation speed detection meter 7);

[0068] The flatness test table 5 tests the flatness of the brake disc 12;

[0069] When the value detected by the flatness detection table 5 is within the tolerance range, the quality of the steering wheel assembly 1 is qualified, that is, the quality of the first bearing 110 and the second bearing 120 is qualified and does not need to be replaced. When the value detected by the flatness detection table 5 exceeds the tolerance range, the steering wheel assembly 1 is disassembled into two parts, the steering wheel and the brake disc 12. After the disassembled steering wheel is assembled with the standard brake disc, it is placed on the detection device for detection. If the detection is unqualified, it means that the first bearing 110 in the steering wheel is unqualified and needs to be replaced; if the detection is qualified, it means that the first bearing 110 in the steering wheel assembly 1 is qualified and does not need to be replaced. In addition, after the disassembled brake disc 12 is assembled with the standard steering wheel, it is placed on the detection device for detection. If the detection is qualified, it means that the second bearing 120 in the brake disc 12 is qualified and does not need to be replaced; if the detection is unqualified, it means that the second bearing 120 is unqualified and needs to be replaced, because the flatness of the brake disc 12 can be judged in advance by a feeler gauge, and the flatness of the brake disc 12 can be ensured to be qualified before the test.

[0070] In this solution, the overall structure of the detection device is simple, which can ensure comprehensive detection, high detection accuracy, and convenient operation during detection.
