[0010] The present invention provides a high-end precision bearing ring modular measurement device and a novel measurement method. It has the following beneficial effects: 1. The present invention significantly optimizes the measurement requirements for multiple shape and position accuracy in a single processing procedure through integrated design. Traditional measurement methods often require multiple devices to detect different parameters separately, while the present invention integrates multiple measurement functions on the same measuring instrument to achieve a high degree of integration. This not only saves the investment cost of the equipment, but also greatly reduces the space occupied by the equipment, leaving more space in the workplace for other production activities. The integrated design also simplifies the operation process, so that processes that previously required multiple settings and adjustments can now be completed in one go, thereby streamlining the entire measurement process, shortening the processing preparation turnaround time, and significantly improving the measurement efficiency. In this way, the present invention not only solves the needs for multiple shape and position accuracy measurements, but also brings users higher economic benefits and operational convenience through the advantages of integration.

[0011] 2. The present invention greatly reduces the workload of the measuring instrument adjusters and the technical difficulty of the users through its unique design and use method. Through modular design and simple operation interface, the operator can master its use method in a relatively short time and can perform accurate measurements without deep professional knowledge. In addition, the height adjustment nut, fine-tuning nut and other designs of the device make the adjustment of the measuring instrument easier and faster, further reducing the difficulty of operation. This easy-to-use feature not only reduces the workload of the operator, but also reduces the company's investment in human resources, saving the company a lot of training costs. At the same time, due to the simplicity of operation, it also greatly reduces the measurement error caused by improper operation, improves the measurement accuracy, and thus ensures the stability of the product's processing quality.

The outer ring measurement module includes a module and positioning block connecting spindle 15 installed on the outer wall of the module base 13, and the end of the module and positioning block connecting spindle 15 is installed with an outer ring end face positioning block 14, and both sides of the outer wall of the outer ring end face positioning block 14 are installed with block pins 18, and a block 17 is installed on the outside of the block pin 18 on one side. The middle part of the outer wall of the outer ring end face positioning block 14 is fixedly connected with an outer ring outer circle V-shaped support 16, and the top of the outer ring outer circle V-shaped support 16 is installed with a measured ring 20. The inner ring measurement module includes an inner ring spindle 19 with a diameter matching the aperture of the measured ring 20 installed on the outer wall of the module base 13, and the measured ring 20 is installed on the outside of the inner ring spindle 19.

[0016] Specifically, the base 1 firmly supports the entire device, while the column 2 serves as the main supporting structure to provide a stable measurement environment. The cantilever beam 4 is connected to the column 2 through the height adjustment nut 3, so that the measuring lever 8 and the corresponding probe 12 can move vertically along the column 2 to adapt to the measurement objects of different sizes. The long-stroke micrometer 5 is used to display accurate measurement data.

The module base 13 is used as the installation base for the outer ring measurement module and the inner ring mandrel 19. It is fixed on the cross moving platform 11 by the fastening screws 10, which ensures the stability of the measurement process. The outer ring measurement module is cleverly designed, in which the module and the positioning block connecting mandrel 15 and the outer ring end face positioning block 14 jointly ensure the accurate positioning of the measured ring 20. The outer ring end face positioning block 14 is used in combination with the block pin 18 and the block 17 to effectively fix the outer ring to prevent it from moving during the measurement process.

Record the highest point value D of the intersection of the inner ring rolling element filling port and the rolling track of the long-stroke micrometer (5). 填 , rotate the cross moving platform (11) moving platform transverse axis micrometer until the cross moving platform (11) moves to the lowest point of the raceway, and record the value D of the lowest point of the raceway of the large stroke micrometer (5). 沟 , inner ring rolling element filling port depth value H 填B =D 填 -D 沟 ; Repeat the operation of S10-S14 to fine-tune the inner ring so that the inner ring probe (122) is at the lowest point of the cross section of the rolling element filling port to be measured. Adjust the height fine-tuning nut (7) so that the long-travel micrometer (5) is adjusted within the appropriate range and set to zero. Record the scale value h of the horizontal axis micrometer of the cross moving platform (11). 填1 as the starting point, and record the value D of the large stroke dial indicator (5) 填1 , continue to rotate the cross moving platform (11) from the starting point and move the horizontal axis micrometer of the moving platform toward the step direction of the inner ring core shaft (19) for h 填2 The distance h 填2 -h 填1 = 1mm, record the value D of the micrometer (5) with the largest stroke 填2 , the inner ring rolling element filling port inclination value ∠A 填B =arctan[|D 填2 -D 填1 | / (h 填2 -h 填1 )]=arctan[|D 填2 -D 填1 | / 1mm]=arctan|D 填2 -D 填1 |; Repeat the operation of S10-S14 to fine-tune the inner ring so that the inner ring probe (122) is at the lowest point of the cross section of the rolling element filling port to be measured. Adjust the height fine-tuning nut (7) so that the long-travel micrometer (5) is adjusted within the appropriate range and set to zero. Record the scale value h of the vertical axis micrometer of the cross moving platform (11). 填1 as the starting point, and record the value D of the large stroke dial indicator (5) 填1 , continue to rotate the cross moving platform (11) from the starting point. The moving distance of the micrometer on the longitudinal axis of the moving platform is recorded. The micrometer scale value h of the cross moving platform (11) on the longitudinal axis of the moving platform is recorded. 填3 , and record the value D of the large stroke dial indicator (5) 填3 , the displacement change of the cross moving platform (11) Δh 填B =h 填3 -h 填1 , the displacement change of the large-stroke micrometer (5) ΔD 填B =|D 填1 -D 填3 |, the inner ring rolling element filling port radius value RfillB=(ΔDfillB2+ΔhfillB2)1 / 2 / 2.
