Description

Technical Field

[0001] This utility model relates to the field of ball cage shell technology, specifically a tooling for detecting the diameter curvature of the spherical surface inside a ball cage shell. Background Technology

[0002] As a crucial component of automotive transmission systems, the diameter curvature accuracy of the spherical surface inside the CV joint's housing has a vital impact on its performance and lifespan. If the diameter curvature of the spherical surface inside the CV joint's housing does not meet design requirements, it can lead to problems such as accelerated wear, increased noise, and reduced transmission efficiency during operation, and may even cause safety accidents.

[0003] Currently, the traditional method for measuring the curvature of the spherical diameter inside the shell of a ball cage mainly relies on manual measurement using simple tools such as vernier calipers and micrometers. These methods have many drawbacks, such as low measurement accuracy, susceptibility to human factors leading to inaccurate results, and low testing efficiency, making it difficult to meet the needs of large-scale production.

[0004] With technological advancements, a fixture for detecting the curvature of the inner spherical diameter of a ball cage shell has emerged. This fixture requires first positioning the ball cage shell, then measuring the curvature of the inner spherical diameter. Since measuring the curvature of the inner spherical diameter requires detecting multiple points on the inner spherical surface of the ball cage shell, this necessitates multiple rotations and repositionings of the ball cage shell, making the process quite cumbersome. Therefore, developing a fixture for detecting the curvature of the inner spherical diameter of a ball cage shell that can effectively solve the above problems is of significant practical importance.

[0050] The movable seat 22 is slidably connected to the fixed seat 21.

[0051] Furthermore, sensor 23 is slidably connected to the bottom of the movable base 22. When the detection fixture is activated, sensor 23 begins operation. Probe 25, driven by probe 24, contacts the inner spherical surface of the ball cage shell. Probe 24 deflects according to the shape of the inner spherical surface. Sensor 23 converts the rotation information of probe 24 into an electrical signal and transmits it to the relevant data processing system. The data processing system calculates the diameter curvature of the inner spherical surface of the ball cage shell based on the signal transmitted by sensor 23.

[0061] The support seat 312 is slidably connected to the slide rail 311;

[0062] A threaded rod 313 is threadedly connected to a support seat 312. The position of the support seat 312 on the slide rail 311 is adjusted by the threaded rod 313 of the moving assembly 31, thereby adjusting the positions of the support block 32 and the rotating assembly 33, so that the ball cage shell is in a suitable detection position.

Then, the limiting pin 335 is inserted into another insertion hole to limit and fix the rotating disk 334. This allows for multi-angle detection of the ball cage shell with only one positioning, which not only simplifies the detection process but also improves the accuracy of the detection.
