AI Technical Summary
Existing butterfly valve machining fixtures lack versatility when fixing workpieces and are difficult to adjust their position freely, making it difficult for workers to align them, reducing processing efficiency and increasing costs.
A butterfly valve machining fixture was designed, comprising a frame, a lifting platform, and a fixed frame. Through a slider and slide plate system controlled by a motor and a microcontroller, the workpiece can be freely adjusted and stably fixed, meeting the machining requirements of valve cylinders with different diameters.
It improves the efficiency of butterfly valve processing and reduces costs. Through the cooperation of motor and microcontroller, it achieves rapid and stable fixation of workpiece and optimal position adjustment, reducing the difficulty of operation for workers.
