AI Technical Summary

Technical Problem

Existing coaxial rotation wear resistance testing devices are prone to output shaft coaxiality deviation due to installation errors and load fluctuations when the ball mold and the ball head test piece rotate coaxially. Furthermore, they lack flexible support force adjustment, resulting in insufficient accuracy and reliability of the test results.

Method used

The design employs a stabilizing mechanism and lubrication components. By adjusting the screw, the upper and lower supports slide against each other. Combined with the shrinkage ring groove structure of the reinforcement, the ball head test piece and the ball mold achieve coaxial and stable grinding. The lubrication components provide continuous lubrication, reducing frictional resistance and buffering vibration.

Benefits of technology

This technology enables stable coaxial rotation of the ball head test piece and the ball mold, reducing testing errors, improving testing accuracy and repeatability, and extending the service life of the device.

Abstract

This utility model relates to the field of wear resistance testing technology, and discloses a wear resistance testing device for a ball mold that rotates coaxially and stably. The device includes an outer frame, a dust collection box fixedly connected to the bottom of the outer frame, a mounting frame fixedly installed on the outer side of the dust collection box, a motor fixedly connected to the top of the mounting frame, and a ball head to be tested clamped to the top of the dust collection box. A stabilizing mechanism is provided on the top of the mounting frame, including a limiting frame. The bottom of the limiting frame is fixedly connected to the top of the mounting frame, and an upper support and a lower support are slidably arranged on the outer side of the limiting frame. The bottom of the lower support is fixedly connected to the top of the mounting frame. An adjusting screw is rotatably connected inside the mounting frame, and reinforcing parts are provided on the inner sides of the upper and lower supports. This utility model achieves coaxial and stable grinding between the ball head to be tested and the ball mold, avoiding test deviations caused by shaft eccentricity and ensuring the consistency and accuracy of wear resistance testing.
