AI Technical Summary

⚠Technical Problem

Existing angular locating pins are prone to wear under frequent disassembly and assembly or dynamic loads, and cannot automatically compensate for accumulated errors, resulting in decreased positioning accuracy. Furthermore, they lack support stability and are susceptible to environmental pollution, which affects production efficiency and equipment lifespan.

⚗Method used

Design an angular spring positioning pin with compensation function. Through the cooperation of the pin and the spring, it can automatically and flexibly compensate for accumulated errors. The environmental adaptability and stability of the device are improved by the dustproof design of the ventilation duct and the multi-point support structure.

🎯Benefits of technology

It enables automatic compensation of accumulated errors under dynamic operating conditions, improves positioning accuracy, reduces maintenance costs, enhances the environmental adaptability and support stability of the device, and extends the service life of the equipment.

Abstract

This utility model discloses an angular spring positioning pin with compensation function, including a diamond pin, a spring, a sliding member, a fixing component, and an upper end cover. The fixing component has a cavity, and the spring and sliding member are horizontally positioned within the cavity, with both ends of the spring contacting the sliding member and the fixing component respectively. The top of the fixing component has a circular hole connecting to the cavity. The upper end cover is annular and is fixed to the outer edge of the hole on the top of the fixing component by bolt a. A crossbar is provided inside the upper end cover, and the top of the sliding member has a mounting hole. The diamond pin rotates around the crossbar, with its lower end inserted into the mounting hole and its upper end inserted into the pin hole of the workpiece. In use, rotating the diamond pin causes its lower end to pass through the mounting hole, driving the sliding member to compress the spring. The spring rebounds, causing the upper end of the diamond pin to compress the pin hole. This utility model can automatically and flexibly compensate for accumulated errors under frequent disassembly and assembly or dynamic loads, preventing low positioning accuracy of the workpiece or damage to the workpiece.
