Then the pressure head starts to press down. During the process of pressing down, the bearing will spread the pawl, and the pawl will spread the rubber part until the bearing is completely loaded into the rubber part;

When the bearing is installed in place, the thin ejector rod at the lower end of the pressure head presses down the inner end of the ejector rod, and the ejector rod rotates around the shaft. Through the principle of leverage, the other end of the ejector rod is tilted upwards to drive the ejector rod upward. Jacking up, jacking up the upper fixing seat and the ratchet mechanism at the same time, so that the ratchet is pulled out from the rubber part, thus completing the assembly of the bearing.

Beneficial effect

The invention relates to a rubber-covered bearing press-in device, which uses a ball joint to connect a detachable automatic reset pawl mechanism. After the bearing is put in, the bearing is pressed under the action of the pressure head. During the pressing process, the bearing will press the pawl Stretch and stretch the inner hole of the rubber part. When the bearing is about to be pressed into place, the top of the pressure head triggers the ejection mechanism, and the ball hinge connection can be separated and the automatic reset pawl mechanism is ejected. Under the action of the spring, the ball hinge connection can be released. The separation and automatic reset pawl mechanism resets, raises the pressure head, and completes the pressing of the bearing. The device has a simple structure and is easy to operate. The pressing process is less destructive to the bearing and the device, has a long service life, and greatly improves work efficiency. .
