However, current methods for detecting the cross-sectional height and runout of backing bearings suffer from complex processes and cumbersome operations. These methods require tedious debugging and operational procedures and make rapid on-site testing difficult, severely impacting testing efficiency and failing to meet the demands for speed and convenience in actual production. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a backing bearing cross-sectional height detection device, which solves the problem of the lack of a device in the prior art for quickly detecting the cross-sectional height and runout data of the outer ring of a backing bearing.

[0007] The advantages of adopting the above technical solution are: the adjustment component slides along the detection seat via the adjustment seat, and its position can be flexibly adjusted along the axial direction of the positioning shaft to adapt to bearings with different axial dimensions; the first clamping block is set perpendicular to the adjustment seat, and in conjunction with the first adjustment bolt, it can quickly tighten or loosen the adjustment shaft by adjusting the width of the first deformation groove, so as to achieve stable fixing and flexible position adjustment of the adjustment shaft, and enable the detection piece to change its position synchronously along the axial direction of the adjustment shaft by the displacement of the adjustment shaft, thereby achieving the purpose of accurate positioning and convenient operation, while improving the adaptability of the device to bearings of different specifications and the detection efficiency.

[0008] The present invention further comprises: the detection component is a dial indicator, the dial indicator includes a detection rod end for contacting the outer diameter surface of the outer ring of the bearing to be tested, the detection rod end being disposed toward the outer peripheral wall of the positioning shaft.

[0009] The advantages of adopting the above technical solution are as follows: the detection component in the above technology is a dial indicator, whose detection rod end directly contacts the outer diameter surface of the bearing outer ring. The dial indicator itself has high-precision measurement characteristics, which can accurately capture minute changes in the bearing outer ring and provide reliable raw data for the calculation of runout data and cross-sectional height. At the same time, the detection rod end faces the outer peripheral wall of the positioning shaft to ensure a reasonable contact position with the bearing outer ring, further ensuring the accuracy of the detection results and meeting the high-precision measurement requirements for key bearing parameters.

[0010] The present invention further includes the following configuration: the adjustment assembly includes a second clamping block, which is connected to the beginning of the adjustment shaft.

A second adjusting bolt is threaded onto the second clamping block for adjusting the width of the second deformation groove so that the second through hole can tighten or loosen the end of the detection rod. The second adjusting bolt passes through the second deformation groove. The adjustment shaft is perpendicular to the end of the detection rod.

[0011] The advantages of adopting the above technical solution are: the setting of the second clamping block in the above technology makes it more convenient to fix and adjust the end of the dial indicator's probe; by adjusting the width and diameter of the second deformation groove through the second adjusting bolt, the probe end can be firmly tightened or flexibly loosened, realizing precise fine adjustment of the probe end position; the adjusting shaft is set perpendicular to the probe end, ensuring that the force direction of the probe end is reasonable, reducing the influence of force deformation during testing, improving the stability of the contact between the probe end and the outer ring of the bearing, and reducing measurement error.

The trapezoidal structure makes it difficult for the slide rail to disengage when sliding in the sliding groove. The fit is tight and the movement is smooth, avoiding shaking or deviation of the adjustment seat during the sliding process. This structural design ensures the stability of the adjustment seat position adjustment, ensures the stability of the reference of the detection piece during the adjustment process, and further improves the accuracy of detection and the reliability of the device operation.

[0015] The advantages of adopting the above technical solution are: the flange at the end of the positioning shaft is detachably connected to the base by connecting bolts, which enhances the stability of the positioning shaft installation and avoids the positioning shaft shaking during testing, thus affecting the measurement accuracy; at the same time, the detachable design makes it easy to replace the positioning shaft with a suitable one according to different bearing models, without the need to replace the entire device, reducing the cost of use, improving the versatility and ease of maintenance of the device, and adapting to diverse testing needs.

[0016] The present invention further includes: a positioning ring integrally connected to the positioning shaft, wherein the side wall of the positioning ring and the outer peripheral wall of the positioning shaft are combined to form a stepped surface for contacting the side wall of the inner ring of the bearing to be tested so that the side wall of the inner ring of the bearing to be tested is in clearance fit with the outer wall of the flange.

[0017] The advantages of adopting the above technical solution are: the stepped surface formed by the positioning ring can make precise contact with the inner ring sidewall of the bearing, which plays an axial positioning role for the bearing, prevents the bearing from moving axially during the test, and ensures the uniformity of the test benchmark; at the same time, it makes the inner ring sidewall of the bearing and the outer wall of the flange fit with a clearance, which reduces friction and wear during bearing installation, protects the bearing accuracy, improves the repeatability and accuracy of the test, and ensures the reliability of the measurement data.

[0018] The present invention further includes a disassembly groove on the flange.

[0019] The advantages of adopting the above technical solution are: the disassembly groove on the flange provides convenient operating space for disassembling the bearing to be tested. When the connection between the positioning shaft and the bearing to be tested is tight, an external tool can be inserted into the disassembly groove and force can be applied to push the bearing to be tested away, thereby easily completing the disassembly of the bearing to be tested, avoiding the laboriousness and inconvenience of the traditional disassembly method. This design improves the efficiency of disassembling and assembling the bearing to be tested, reduces the operation time, and enhances the practicality and ease of operation of the device.

[0026] 2. Next, move the adjusting seat to the middle position of the testing seat, adjust the first adjusting bolt of the first clamping block, so that the adjusting shaft drives the second clamping block to move, and then drives the dial indicator to move synchronously until the end of the dial indicator's testing rod is aligned with the middle of the outer diameter surface of the bearing outer ring.
