Secondly, when the power source drives the measurement, the driving force transmission may be unstable, the differential bounce detection relies on external friction drive or low-precision motor drive, and the measured part may appear uneven speed or jitter when rotating, thereby affecting the measurement accuracy. Moreover, the application range is limited, and different shapes of measured workpieces (such as rotating parts with spline) need special clamping structure, which lacks applicability and is difficult to adapt. In addition, during the detection process, the spline of the differential is in direct contact with the clamp, if the clamping method is unreasonable or lacks buffer structure during movement, it is easy to scratch the surface of the workpiece, affecting the assembly accuracy and service life, and the noise is large.

[0029] The spline clamp 11 and movable piece 12 are provided with through hole 10, and the through hole 10 of spline clamp 11 and movable piece 12 is one-to-one correspondence;The anti-drop peg 131 sequentially passes through the through hole 10 of both, and the activity range of spline clamp 11 and movable piece 12 is limited in the circumferential range of through hole 10.

[0030] The first rubber ring 3 is arranged between the spline clamp 11 and the movable element 12 and between the movable element 12 and the mounting seat 13, and can constrain the anti-drop pin 131. Preferably, the first rubber ring 3 in the embodiment is an O-shaped rubber ring, which is respectively arranged on the lower surface of the spline clamp 11 and the lower surface of the movable element 12. The diameter of the first rubber ring 3 is smaller than that of the spline clamp 11, the movable element 12 and the mounting seat 13. The O-shaped rubber ring can effectively constrain the anti-drop pin 131, so that the spline clamp 11 and the movable element 12 are kept in the set position and movement, avoiding loosening caused by accidental vibration or external force, and enhancing the stability and safety of the device. Moreover, the elastic property of the O-shaped rubber ring allows the anti-drop pin 131 to slide within a small range, and can automatically return to the original position after loosening, improving the smoothness of operation and ensuring that the detection assembly maintains the accurate original state during use. In addition, the O-shaped rubber ring has a certain damping function, which can effectively reduce the jumping error caused by vibration during equipment operation, and ensure the accuracy of detection data.

[0031] The lower surface of the spline clamp 11 is provided with a first guide groove 111, and the upper surface of the movable element 12 is provided with a first guide block 121 matched with the first guide groove 111. The lower surface of the movable element 12 is provided with a second guide block 122, and the upper surface of the mounting seat 13 is provided with a second guide groove 132 matched with the second guide block 122. Since the first and second guide grooves 132 and the guide blocks are mutually embedded, the rotation or deviation of the spline clamp 11 and the movable element 12 in the horizontal direction is limited, the rigidity of the assembly is improved, and the overall device is more stable, meeting the high-precision detection requirement.

[0032] The first guide groove 111 and the second guide groove 132 are orthogonally arranged in space, and the first guide block 121 and the second guide block 122 are orthogonally arranged in space, so that the assembly is limited in two mutually perpendicular directions, avoiding deviation or rotation caused by one-way constraint, and improving the precision and stability of the run-out detection.

Moreover, due to the constraint of the limiting shaft in the sliding groove, the sliding block shaft 221 cannot rotate or move laterally, thereby avoiding measurement error caused by rotation and improving the reliability of detection data.

[0034] The outer wall of the connecting rod 223 is provided with a second sliding groove 6, and the corresponding base connecting pipe 21 is provided with a matched shaft hole 62; the connecting rod 223 is provided with a second limiting shaft 61 which passes through the shaft hole 62 and the second sliding groove 6 in sequence, connects the driving shaft 22 with the base connecting pipe 21, and cooperates with the second sliding groove 6 to make the driving shaft 22 only move along the second sliding groove 6, so as to prevent over-sliding or falling out, enhance the safety and reliability of the device, and avoid damage caused by misoperation.

[0035] The first sliding groove 5 and the second sliding groove 6 are orthogonally arranged in space; the first limiting shaft 51 is installed in the first sliding groove 5, the second limiting shaft 61 is installed in the second sliding groove 6, and the two are also in an orthogonal relationship. In both directions, the limiting shafts can effectively resist external vibration or impact interference, ensure that the equipment can still operate stably in a high-vibration or complex environment, and improve the reliability of the detection result.

[0036] The base connecting pipe 21 is provided with a mounting groove 63 for mounting the second rubber ring 4, and the shaft hole 62 is arranged in the mounting groove 63; the second rubber ring 4 is mounted in the mounting groove 63 to hide the shaft hole 62, and also can prevent the second limiting shaft 61 from falling off; preferably, the second rubber ring 4 in the embodiment is an O-shaped rubber ring.

[0037] The bottom end of the sliding block shaft 221 is fixedly connected with the first spring 7, so that the sliding block shaft 221 is always moderately constrained during movement, the shaking or misalignment is reduced, the stability of the movement track is improved, and the detection accuracy is ensured.

[0038] The outer wall of the driving shaft 22 is provided with the second spring 8, which extends from the top end of the driving shaft 22 sleeve to the top end of the base connecting pipe 21. During installation, the assistance of the spring can reduce the external force required to be applied by the operator, avoid installation difficulties caused by heavy parts or tight cooperation, and improve the installation convenience.

[0039] The base connecting pipe 21 is internally provided with a sliding sleeve 9 capable of reducing friction, which is used to effectively reduce the friction between the driving shaft 22 and the inner wall of the base connecting pipe 21, make the movement of the driving shaft 22 more stable and smooth, avoid jamming or resistance caused by excessive friction, and improve the overall operation efficiency of the equipment.

[0040] In use, the device can be placed vertically and will not be disturbed by external interference, the driving part 2 is connected with the driving device, the spline of the clamp part 1 is inserted into the to-be-detected element, the components of the device are ensured to be in a normal working state during the bounce detection process, the movement of the components is driven by the driving device, and the detection of the target object bounce is realized.

[0041] By setting the first rubber ring 3 capable of restraining the anti-falling pin 131 to limit the movement range, the spline clamp 11 and the movable piece 12 can be firmly limited within the rubber ring circumferential range, preventing falling or deviation during movement, and ensuring the stability and reliability of the assembly. Moreover, the rubber ring not only provides a restraining force, but also provides a rebound force when subjected to external force, so that it can automatically reset after sliding within a small range, reducing the frequency of manual adjustment and improving operation efficiency. Secondly, the cooperation design of the guide groove and the guide block ensures the accurate guidance of the movable piece 12 and the spline clamp 11 during movement, avoids unnecessary shaking or deviation, and improves the movement accuracy of the assembly; at the same time, the orthogonal arrangement in space enables the movement of the assembly in multiple directions to be effectively controlled, enhancing the overall stability and movement flexibility of the assembly. In addition, sliding fit is adopted between the driving shaft 22 and the base connecting pipe 21, and between the sliding block shaft 221 and the driving shaft 22 sleeve, allowing axial movement, while the movement range is limited by the sliding groove and the limiting shaft, realizing flexible and controllable movement.
