AI Technical Summary

Technical Problem

Existing technologies have difficulty simultaneously positioning, clamping, and releasing multiple casting blanks, resulting in low work efficiency.

Method used

A positioning device for machining casting blanks was designed, including components such as a base plate, a support plate, a secondary plate, a positioning wheel, a locking wheel, a vertical shaft, and a top plate. The rotation of the vertical shaft enables the simultaneous positioning, clamping, and release of multiple casting blanks. The cooperation between the top plate and the top wheel reduces friction, the elastic support of the spring improves stability, the threaded seat and the screw adjust the clamping size, and the friction block and the limit gear structure ensure the stability and angle adjustment of the castings.

Benefits of technology

It enables simultaneous positioning, clamping, and release of multiple casting blanks, simplifying the operation process, shortening the operation time, improving work efficiency, and adapting to casting blanks of different sizes and angles, thereby improving positioning accuracy and stability.
