Spherical processing tooling improvements
The structural details of the component are illustrated in Figure 1. This particular component is manufactured using mass production techniques.
An innovative approach has been developed to enhance the machining process. This method leverages the rotational principle of a disc, where the cutting tool is mounted onto the rotating disc. A push rod, which facilitates the swinging motion of the disc, is welded along the outer edge of the disc. By applying an external force to this push rod, the disc undergoes a circular motion along its circumference. Consequently, the tool follows a trajectory that describes a circular path with a radius of 60mm. The tooling design is outlined in Figure 2 and comprises two primary components.
The first component includes a rotary disc, a cutting tool, a bushing, an upper and lower washer, a dust cover, and a shaft. These elements are attached to the base, which is itself secured onto the lathe saddle. To begin the assembly process, the base is positioned on the saddle and fastened using a φ12mm taper pin. The bushing is installed within the central hole of the rotary disc, while the shaft is mounted on the base and connected via the screw holes. The lower washer is then placed over the shaft and fixed with three screws tightened against the base’s upper plane. Subsequently, the assembly is mounted onto the shaft, followed by securing the upper washer nut and fitting the dust cover.
The second component consists of a sliding seat, a bushing, a coupling shaft, and a pin shaft. The bushing is fitted into the sliding seat, which is subsequently affixed to the square tool holder. The coupling shaft is inserted into the sliding hole, with its left end connected to the turntable push rod. A pin shaft is then inserted to couple the first and second assemblies together. During operation, lateral movement of the intermediate slide plate causes the coupling shaft to shift laterally, inducing a swinging motion in the push rod of the rotary disc. This action results in the turntable executing a rotational motion, enabling the machining of the SR60mm inner spherical surface.
Upon implementing the enhanced tooling for machining the SR60mm inner spherical surface, several notable improvements were observed. Firstly, during the lathe operation, the horizontal sliding feed of the slide plate ensures uniform and stable tooling, resulting in a surface roughness value (Ra) below 3.2μm post-processing. Secondly, the automated feed mechanism during tooling significantly reduces operator fatigue and labor intensity. Additionally, sealing grooves are incorporated at both ends of the rotary disc to prevent chip ingress into the internal areas of the holder shaft.
These enhancements not only improve machining efficiency but also contribute to better surface quality and operational safety. Overall, the adoption of this innovative tooling setup represents a significant advancement in machining precision and reliability.
