Description

Technical Field

[0001] This utility model relates to the field of automotive planar bearing testing technology, specifically to a dynamic performance testing platform for automotive planar bearings. Background Technology

[0002] In the manufacturing process of automotive thrust bearings, dynamic performance testing is a crucial step in ensuring bearing quality, directly impacting the stability and safety of vehicles during operation. Current technology typically employs a dynamic performance testing platform for automotive thrust bearings, consisting of a drive mechanism and a clamping mechanism. The drive mechanism simulates the bearing's operating state, while the testing elements collect performance parameters.

[0003] The following problems exist in current use: 1. The drive testing section and bearing assembly section of the existing testing platform are mostly set up independently, and the two are spliced ​​together by simple connectors, resulting in poor overall structural stability. When the drive motor is running at high speed for dynamic testing, vibration and displacement are prone to occur, affecting the test accuracy. At the same time, the wiring structure of the drive motor is messy, making installation and maintenance inconvenient. 2. The height adjustment and horizontal position adjustment structure of the bearing clamping mechanism of the existing testing platform are poorly designed. The adjustment process is cumbersome and has low precision, making it difficult to quickly adapt to different specifications of automotive flat bearings. Moreover, the bearing clamping firmness is insufficient, and the bearing is prone to loosening during dynamic testing, resulting in distorted test data. Utility Model Content

[0027] The working principle of this utility model is as follows: First, according to the specifications of the automotive planar bearing to be tested, the lifting platform 26 is driven up and down along the lifting slide bar 23 via the screw assembly 25 to adjust to a suitable testing height. Then, the handwheel of the drive screw 29 is rotated, causing the slide block 28 to slide along the slide rail 27, aligning the bearing clamp with the output end of the drive motor 13. Next, the movable clamp 211 is flipped over, placing the bearing to be tested on the fixed clamp 210. The movable clamp 211 is then flipped again to fit the bearing, and the locking screw 212 is tightened, allowing the movable clamp 211 and the fixed clamp 210 to securely clamp the bearing. The drive motor 13 is started, and its output end drives the bearing to rotate, simulating its working state, and cooperating with external detection elements to collect dynamic performance parameters. After the test is completed, the locking screw 212 is loosened, the movable clamp 211 is flipped over, and the tested bearing can be removed.
