Description

Technical Field

[0001] This utility model relates to the field of bearing measurement, and in particular to a height adjustment component for measuring bearing races. Background Technology

[0002] Bearings are crucial components used for rotating supports in mechanical bodies. A bearing typically consists of two raceways forming the outer and inner rings, with a raceway between them for rolling rollers or balls. Bearings come in a wide variety of types and varieties, and the raceways, depending on the bearing type, may have features such as dustproof grooves, relief grooves, and snap ring grooves. Measurements are also required for determining the maximum diameter and symmetry of the spherical surface. Before leaving the factory, bearings often need to be measured to ensure that deviations meet standards. Existing measuring instruments typically include two fixed measuring points and one moving measuring point. During adjustment, all three measuring points must be at the same height, and once adjusted, their height remains constant. This doesn't affect diameter measurements with sufficient cylindrical width, but for raceways requiring specific height, the groove positions must be highly consistent to ensure each measurement matches the actual needs. However, conventionally adjusting the height of the three washers is inefficient. Therefore, it is necessary to optimize bearing raceway measuring instruments to allow for quick adjustments to the measurement position based on the specific requirements of different raceways. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a height adjustment component for measuring bearing rings that is more convenient to use and adjust.

[0004] To achieve the above objectives, this utility model provides a height adjustment assembly for measuring bearing races, including an operating table. The operating table is provided with a mounting base, a support member, and an adjusting rod. The mounting base is for placing the races. The support member is located below the mounting base and forms an anti-rotation fit with it. The adjusting rod is located at the center of the mounting base and forms a screw fit with it. The adjusting rod can rotate relative to the support member and forms a vertical limiting fit.

[0005] The advantages of the above technical solution are: a mounting base, a support, and an adjusting rod are set on the operating table, the mounting base and the adjusting rod are screwed together, and the support forms anti-rotation and rotational engagements with the mounting base and the adjusting rod respectively. During the process of rotating the adjusting rod to screw it into the mounting base, the anti-rotation engagement between the mounting base and the support causes the mounting base for placing the ring to rise or fall, thereby adjusting the measurement position to match the actual requirements. There is no need to adjust the position of the test piece, which facilitates measurement and adjustment.

[0006] The present invention can be further configured as follows: the mounting base includes a through hole located in the middle and a plurality of first rods, the plurality of first rods being spaced apart at the through hole and extending toward the center position, and the plurality of first rods forming a plurality of clearance intervals; the support member is provided with a plurality of vertically extending second rods, the plurality of second rods being spaced apart and respectively passing through the plurality of clearance intervals.

[0007] By further designing the mounting base, a through hole and a first rod are provided in the middle, and several first rods are spaced apart at the through hole to form a clearance interval. Several vertically extending second rods are provided on the support member, and several second rods are respectively inserted at several clearance intervals, thereby forming an anti-rotation fit between the mounting base and the support member.

[0008] The present invention can be further configured such that: the support member is provided with an abutting part at the interval of a plurality of second rods, and the abutting part can abut against the lower part of the first rod.

[0009] By further designing the support member, abutment portions are provided at intervals corresponding to several second rods. These abutment portions, which abut against the lower part of the first rod, can provide initial support for the mounting base during installation, facilitating both installation and subsequent adjustments.

[0010] The present invention can be further configured such that: the mounting base includes a ring edge, and the ring edge is provided with a plurality of openings spaced apart circumferentially.

[0011] By further configuring the device, a ring edge is provided on the mounting base to match the collar to be tested for placement. Several openings are provided around the ring edge, allowing the test piece to be inserted into the openings and then fit into the collar when measuring the inner wall of the collar.

[0012] The present invention can be further configured such that: a detachable limiting nut is provided on the support member, the limiting nut can form an abutment limit with the upper end of the adjusting rod, and the lower end of the adjusting rod abuts against the support member.

[0013] By further configuring the device, a detachable limiting nut is installed, which then acts as a stop for the upper end of the adjusting rod. The lower end of the adjusting rod then abuts against the support, causing the mounting base to rotate and move up and down while its vertical position remains unchanged, resulting in greater stability.

[0014] The present invention can be further configured such that an operating hole is provided at the end of the adjusting rod.

[0015] By further designing the adjustment rod, an operating hole is provided at the end of the rod, such as a polygonal hole in this application, to facilitate the operator to rotate the adjustment rod. Attached Figure Description
