[0002] The pin bushing is a hardened steel insert that strengthens the dowel pin hole. Before the pin bushing is put into use, a cutting device is required for the pin bushing processing.

[0003] However, in the existing technology, the clamping and fixing of the pin sleeve requires manual placement of the pin sleeve between the clamping and fixing components, and manual support of the position of the pin sleeve before the clamping and fixing components fix the pin sleeve. This is not only inconvenient to operate, but also risky and easily injures the operator. For this reason, we propose an automatic positioning and cutting tool for pin sleeve processing.
