An upper detection steel ball positioning sleeve 19 and a lower detection steel ball positioning sleeve 20 are respectively provided at both ends, an upper detection steel ball 03 and a lower detection steel ball 05 are provided inside the outer ring 07, the upper detection steel ball 03 and the lower detection steel ball 05 are symmetrically arranged up and down, a gasket 04 is provided between the upper detection steel ball 03 and the lower detection steel ball 05, a dynamic detection head 06 is provided inside the lower detection steel ball 05, and a dynamic detection head 06 is provided inside the lower detection steel ball 05. The lower part of the outer ring 07 is connected with the lower detection steel ball 05 positioning sleeve through a positioning pin 18, a connecting plate 17 is provided on the outside of the fixed detection head 02, a lower detection mold fixing plate 21 is provided below the lower detection steel ball 05 positioning sleeve, a clamping block 14 is provided above the positioning slide 15, the dynamic detection head is connected to the detector 01 through a sliding shaft 13, and the position adjustment detection is realized through the detector 01, and a compression spring 11 is provided around the sliding shaft 13.

[0021] The setting of the detector 01 mounting plate and the column 09 can firmly support and position the measuring instrument to ensure the accuracy and reliability of the measurement. The measuring instrument is connected to the workbench 12 through the sliding shaft 13, and can realize horizontal movement on the workbench 12, which is convenient for comprehensive detection of the double raceways of the bearing outer ring 07. The setting of the positioning slide 15 and the self-lubricating bearing 16 can ensure the accurate positioning of the sliding shaft 13 on the workbench 12 to avoid measurement errors caused by position offset. The setting of the upper detection steel ball 03 positioning sleeve and the lower detection steel ball 05 positioning sleeve can ensure that the outer ring 07 and the inner ring are relatively stable to avoid unnecessary offset or rotation during the measurement process. The setting of the connecting plate 17 can provide a stable connection point so that the fixed detection head 02 can accurately contact the outer ring 07 to ensure the accuracy and reliability of the measurement.

The outer ring 07 of the double-row ball bearing to be tested is placed on the workbench 12 to ensure that the position of the bearing outer ring 07 is fixed.

[0022] The position of the sliding shaft 13 is adjusted by positioning the slide 15 and the self-lubricating bearing 16, so that the fixed detection head 02 can accurately contact the upper raceway of the bearing outer ring 07. The dynamic detection head 06 is connected to the detector 01 through the sliding shaft 13. When the detector 01 is started, the dynamic detection head 06 will move along the raceway of the outer ring 07, while the fixed detection head 02 remains stationary, so that the geometric parameters of the upper raceway and the lower raceway, such as diameter, roundness, surface roughness, etc., can be detected respectively. During the movement, the dynamic detection head 06 will collect data through the detection elements (such as sensors, photoelectric detectors, etc.) on the fixed detection head 02 and the positioning sleeve of the lower detection steel ball 05 The collected data will be analyzed and processed by the processor of the detector 01 to evaluate the quality of the raceway of the outer ring 07 of the bearing. If the test result does not meet the preset standard, the detector 01 can adjust the position of the sliding shaft 13 and re-test, or output the test results and adjustment suggestions. When all tests are completed, the detector 01 will output the final report, including the quality assessment of the raceway of the outer ring 07 of the bearing and the repair or replacement suggestions that may be required. The role of the compression spring 11 is to provide a certain reaction force during the test process to ensure that the contact force between the dynamic test head 06 and the outer ring 07 is constant, so as to obtain accurate test results. The connecting plate 17 and the lower test mold fixing plate 21 provide additional support and positioning to ensure the stability and accuracy of the entire test device.

[0023] The structure adopts high-precision measuring instruments, non-contact digital eddy current displacement sensors or contact digital sensors, with a resolution of up to 0.1um and a measurement accuracy of 1um. The upper and lower double-row steel ball multi-point detection mechanism simultaneously measures the two raceways of the outer ring 07, making the detection more accurate and improving the detection accuracy, eliminating the error caused by three-point detection, thereby eliminating the defect of poor clearance after the final selection of steel balls due to insufficient detection accuracy.
