The force sensor 16 is used to detect the applied pressure and send the pressure parameters to the computer for recording. The pressure body 12 is used to contact the part to be inspected and apply pressure to the part to be inspected. Figure 3 The pressure body 12 is a U-shaped structure, and has two pressure surfaces 121. The two pressure surfaces 121 are arranged opposite to each other, one above and one below. When different pressure surfaces 121 contact the parts to be inspected, they are used to apply forces in different directions to the parts to be inspected. In an up and down stroke of the pressure drive component 11, they can respectively contact the upper and lower force points of the part to be inspected 5 to complete the jump detection in two force directions.
[0034] Optionally, the pressure surface 121 is a plane or a curved surface, and the curved surface can increase the contact area with the part to be inspected 5 to avoid damaging the part to be inspected 5 when pressure is applied.
[0035] The detection module 3 includes a displacement sensor 34, which is used to detect the displacement of the bearing block position of the part to be inspected. In this embodiment, the displacement sensor 34 is preferably a dial indicator. The detection module 3 also includes a position adjustment module, which includes a horizontal position adjustment module 32 and a height adjustment module 31.

[0037] Optionally, an accordion-type dust cover 6 is installed at both the axial translation module 21 and the pressure driving assembly 11 .
[0038] This solution has the following advantages:
[0039] 1. Use three claws to clamp the connecting shaft, equipped with a 360-degree rotation function, which can achieve a full rotation and facilitate the rapid switching of the force point;
[0040] 2. The axial position of the chuck can be adjusted to realize the detection of parts of different lengths;
[0041] 3. The displacement sensor 34 can be moved axially and in height to measure the position accuracy and alignment;

By using the pressure body 12 with upper and lower pressure surfaces, the pressure driving assembly 11 can contact the upper and lower force points of the part to be inspected 5 in an upper and lower stroke, complete the vibration detection in two force directions, and improve the detection efficiency.
[0043] The method for detecting multi-directional runout of a bearing stop after the input shaft and the connecting shaft are assembled comprises the following steps:
[0044] The chuck 24 is used to clamp the part 5 to be inspected. Figure 4 As shown, it is assembled from an input shaft 52 and a connecting shaft 53, the chuck 24 is clamped on the outer circle of the connecting shaft 53, and the spline end of the input shaft 52 is placed between the two pressure surfaces 121;
[0045] Adjust the position of the displacement sensor 34 so that the displacement sensor 34 contacts the bearing stop 51;
[0046] The pressure driving assembly 11 applies pressure to the part 5 to be inspected at a preset speed and pressure, and uses the displacement sensor 34 to detect the gap generated by the pressure applied at the bearing stop 51 of the part 5 to be inspected, and obtains radial runout data, which is sent to the computer for recording;
[0047] The pressure driving assembly 11 performs an ascending and descending stroke, respectively making the two pressure surfaces 121 contact the part to be inspected 5, thereby completing the radial runout detection under forces in two directions;
[0048] The chuck 24 is driven to rotate by the chuck rotation drive assembly 23 to rotate the part 5 to be inspected and then inspected again after being rotated by a set angle. This process is repeated multiple times until the radial runout inspection under the required direction of force is completed.

The distance sensor 122 is used to detect the length of the part to be inspected entering the pressure body 12. The distance sensor 122 can be an infrared or ultrasonic distance sensor. The distance sensor 122 is electrically connected to the axial translation module 21. When the distance between the spline end of the part to be inspected 5 and the distance sensor 122 reaches a set value, the distance sensor 122 sends a stop command to the axial translation module 21 to ensure the contact length between the pressure body 12 and the part to be inspected 5, thereby further improving the detection efficiency.
