AI Technical Summary
The existing technology lacks CNC lathe machining fixtures suitable for the main holes and center holes of valve body parts in automotive braking systems, which makes it difficult to achieve efficient machining, especially when the dimensions change frequently during the trial production stage of new products.
Design a CNC lathe dual-process machining fixture, including components such as pads, upper plates, left vertical plates, base plates, connecting discs, CNC lathe spindles, fixture positioning bodies, right vertical plates, circular washers, and locking screws. By using a magnetic base and lever dial indicator for alignment, ensure that the axes of the main hole and eccentric hole of the workpiece coincide with the axis of the CNC lathe spindle, enabling quick changeover and high-precision machining.
It enables simultaneous machining of two hole processes on a CNC lathe, ensuring machining accuracy. It is suitable for batch production and R&D prototype products. It has a compact and practical structure, can perform sequential machining as needed, and can quickly change positioning parts, reducing tool costs and preparation time.
