The part structure is shown in Figure 1. The part production type is mass production.
Improved method
The improvement method is to use the principle of the disc rotation, the cutter is mounted on the rotary disc, and a push rod for pushing the rotary disc is welded at the outer circle of the rotary disc, and an external force is used to push the push rod to make a swing, so that the rotary disc produces a circumference. For rotary motion, the tool will also make a trajectory of R60mm circular motion. The tooling structure is shown in Figure 2 and consists mainly of two parts.
The first part consists of a rotary disc, a cutter, a bushing, an upper and lower washer, a dust jacket and a shaft. The base is connected to the base. The base is fixed on the lathe saddle. First, the base is placed on the saddle, and the φ12mm taper pin and the saddle are inserted. Fasten, the bushing is installed in the inner hole of the rotary disc, the shaft is mounted on the base, and is connected with the screw hole of the base. The lower washer is placed on the shaft and fastened by fastening the three screws to the upper plane of the base, and then the assembly is mounted on the shaft. , fasten the upper washer nut and put on the dust jacket.
The second part is composed of a sliding seat, a bushing, a coupling shaft and a pin shaft. The bushing is installed in the sliding seat, and then the sliding seat is fixed on the square tool holder, and the coupling shaft is inserted into the sliding hole, and the left end of the coupling shaft is The turntable push rod is coupled, the pin shaft is inserted, the first part and the second part assembly are coupled into one body, the middle slide plate is fed in the lateral direction, and the joint shaft is moved in a lateral direction to cause the push rod on the rotary disk to generate a swing, thereby returning The turntable produces a swivel motion to machine the S R60mm inner spherical surface.
2. Improved effect
After the improved tooling processing SR60mm inner spherical surface, the specific effect: 1 horizontal sliding feed of the sliding plate in the lathe, the tool processing is even and stable, and the surface roughness value after processing is R a < 3.2μm. 2 When the tool is fed, it is a motorized feed, which reduces the labor intensity of operation. 3 There are sealing grooves on both ends of the rotary disc to prevent chips from entering the inside of the holder shaft.
