Description

Technical Field

[0001] This utility model relates to the field of bearing testing technology, specifically a bearing equipment positioning and testing seat. Background Technology

[0002] In modern industrial manufacturing, bearings are indispensable core components of mechanical equipment, and their quality and performance directly affect the operating accuracy, stability, and service life of the equipment. In the bearing production process, accurately detecting key parameters such as the perpendicularity of the bearing's inner bore to the end face and its linear runout is a crucial step in ensuring bearing quality meets industrial application requirements. Currently, the industry commonly uses a fixed bearing outer ring for positioning, followed by the detection of these key parameters.

[0003] However, existing bearing testing devices have significant limitations in practical applications, the most prominent being their poor adaptability to diverse bearing types. Currently, most bearing testing devices use a triaxial fixture as the bearing fixing structure. This fixture is based on the principle of three-point circular fixation, using the clamping force at the three shaft ends to stably fix the outer ring of the bearing, thereby achieving bearing positioning. When testing traditional cylindrical bearings, this triaxial fixture can quickly and stably fix the bearing due to its structural characteristics, ensuring the smooth progress of the testing work.

[0004] However, with the continuous development of industry, the structure and shape of bearings are becoming increasingly diversified. Square bearings, elliptical outer ring bearings, and bearings with irregularly shaped housings are gradually being widely used in precision instruments, special machinery, and other fields. Because the design principle of triaxial clamps relies on the geometric characteristics of a circular outer ring, effective clamping and fixation cannot be achieved for irregularly shaped bearings with non-circular outer rings. When dealing with square bearings, the three clamping points of the triaxial clamp cannot precisely match the sides or corners of the square, making it difficult to provide a uniform and stable clamping force. For elliptical outer ring bearings and bearings with irregularly shaped housings, the problem of clamping failure due to irregular shapes also exists. This makes existing bearing testing devices unable to meet the testing requirements of irregularly shaped bearings, severely restricting the development and application scope of bearing testing technology.

[0058] Overall fixing assembly 14: an assembly used to fix the three sets of bearing fixing assemblies to the base platform 1, including base ring plate 15, fixing bolts 16 and clamping plate 17, which can prevent the single shaft top rod 9 from sliding when fixed and facilitate overall movement;

[0059] The base ring plate 15 is in the shape of a circular ring plate and is set at the bottom of the base platform 1. It has three sets of symmetrically distributed screw rings on its circumference, which are used in conjunction with the fixing bolts 16 to achieve overall fixation.

[0060] Fixed bolt 16: A bolt threaded into the threaded ring of the base ring plate 15, extending through the base platform 1, and fitted with a clamping plate 17, used to fix the three sets of bearing fixing assemblies to the base platform 1;

[0062] Bolt relief groove 18: An arc-shaped groove is opened on the base platform 1 at the location of the three sets of fixing bolts 16, which facilitates the slight adjustment of the overall fixing assembly 14 along the groove and avoids the single-axis push rod 9 and the fixing bolts 16 from obstructing each other.

[0063] Flexible gasket 19: A gasket set at the bottom of clamping plate 17 to enhance friction, prevent loosening after clamping, and avoid rigid contact between clamping plate 17 and the upper surface of third bearing fixing assembly 6.

[0064] Working Principle: Initially, the bearing to be tested is placed in the center of the base platform 1. Four sets of support feet 2, together with the base ring plate 15, form a stable support structure, ensuring the base platform 1 is level and stable, providing a reliable benchmark for subsequent fixing operations. The center hole 3 in the center of the base platform 1 provides space for the probe of the testing equipment, facilitating the fit between the probe and the bearing inner ring. Subsequently, three sets of coaxially stacked bearing fixing assemblies play a core positioning role. The bottommost first bearing fixing assembly 4 is welded and fixed to the base platform 1, serving as the base of the entire fixing system. The second and third bearing fixing assemblies 5 and 6 can rotate flexibly around their axis through the snap-fit ​​design of the rotating convex ring 8 and the rotating groove 7. This rotatable structure allows the operator to manually adjust the angles of the upper two sets of bearing fixing assemblies according to the bearing's outline when dealing with irregularly shaped bearings, ensuring that the force direction of the single-axis push rod 9 is precisely aligned with the key force points on the irregular surface of the bearing. Multiple sets of single-axis push rods 9 are key actuators for achieving diverse bearing fixing. Each set of single-axis push rods 9 is threadedly connected to the horizontal screw holes 10 on the side of the bearing fixing assembly via adjusting screws 12, forming a telescopic adjustable structure. After the bearing is placed in position, the operator rotates the convenient handle 11 to drive the adjusting screw 12 to screw inward along the horizontal screw holes 10, causing the flexible push head 13 to gradually approach the outer ring surface of the bearing. The flexible push head 13 is made of elastic material and can undergo slight deformation when in contact with the bearing, adaptively conforming to irregular surfaces such as curved surfaces and inclined surfaces, providing sufficient clamping force while avoiding damage to the bearing surface caused by rigid contact. For traditional cylindrical bearings, the nine sets of horizontal screw holes 10 symmetrically distributed in a 120° circle on the three sets of bearing fixing assemblies can achieve stable clamping with three-point positioning; while for square, elliptical, or irregularly shaped bearings, the operator can flexibly adjust the single-axis push rods 9 at different heights and angles, and firmly fix the irregularly shaped bearing through multi-point and multi-directional coordinated clamping. After the single-axis push rods 9 have completed the initial fixing, the overall fixing assembly 14 starts the secondary reinforcement process. The base ring plate 15 serves as the bottom support component and is connected to the base platform 1 via three sets of fixing bolts 16. The operator places the clamping plate 17 onto the fixing bolts 16 and rotates the nut to press one side of the clamping plate 17 against the third bearing fixing assembly 6. The presence of the flexible gasket 19 effectively enhances friction, preventing loosening after fixing. The bolt groove 18 on the base platform 1 allows for slight angle adjustments to the fixing bolts 16, avoiding spatial interference with the single-axis push rod 9 and ensuring the compactness and stability of the overall structure. Through the locking of the overall fixing assembly 14, the three sets of bearing fixing assemblies and the base platform 1 form a rigid whole. This not only prevents the single-axis push rod 9 from sliding when fixing irregular curved surfaces but also facilitates the movement of the fixed bearing assembly to the testing station to complete the testing of key parameters such as inner hole perpendicularity and linear jump. Throughout the entire positioning and testing process, each component performs its function and works closely together, ensuring efficient fixing of traditional bearings while achieving broad adaptability to irregularly shaped bearings, significantly improving the versatility and efficiency of bearing testing.
