Description

Technical Field

[0001] The utility model relates to the technical field of bearing detection, in particular to a groove diameter detection device for a bearing ring. Background Art

[0002] The bearing ring is an annular part of a radial rolling bearing with one or more raceways. The bearing groove diameter refers to the distance between the contact points of the inner and outer rings. During the use of the bearing, if the bearing groove diameter is large, the bearing will not work properly and affect the operation of the machine; if the bearing groove diameter is small, the bearing will be too tight and cause premature damage to the bearing. Therefore, correctly measuring the bearing groove diameter is one of the keys to ensuring the bearing performance and service life. Therefore, the bearing needs to be inspected for groove diameter after production is completed. For example, patent application number CN202211454981.8 is a bracket bearing outer ring groove diameter measuring device, including a base, a detection bracket is provided on the base, a lower detection unit positioning block is provided on the right side of the detection bracket, and a displacement sensor and a tensioning cylinder are provided on the upper part of the detection bracket; the lower detection unit positioning block is provided with a spring sheet extending to the left, and the left end of the spring sheet is connected to a lower detection head mounting frame, and a tensioning bracket is provided on the lower detection head mounting frame. When the tensioning cylinder piston rod contracts, the lower detection head mounting frame is driven to move upward through the tensioning bracket; an upper detection head is provided on the left side of the detection bracket, a lower detection head is provided on the left side of the lower detection head mounting frame, and an alloy rod matching the displacement sensor probe is provided on the lower detection head. The measuring device can measure and compare the groove diameter of the outer ring of the bracket bearing with that of the standard part, quickly screen out defective products whose groove diameter does not meet the quality standards, and realize automatic measurement of the groove diameter of the outer ring of the bearing, thereby greatly improving the detection efficiency of the processing quality of the outer ring of the bearing. In the above technical scheme, the detection mechanism is difficult to adjust and it is not easy to detect bearings of different specifications. Due to the different specifications of the bearings, different detection devices need to be replaced when detecting bearings of different specifications, which affects the detection efficiency.

The two inner clamping plates 603 are connected to the two first screw thread sleeves 607 respectively, and the two outer clamping plates 604 are both installed with depth gauges 602.
