The main processing surface of the parts can be divided into two groups:1. Phi 32 mm hole at the center of machining surfaceThis set of machining surface including: phi 32 mm of two end face and the hole and chamfering, phi 16 mm of two end face and hole and chamfering.2. To phi 16 mm hole machining surfaceThis includes a set of processing surface, phi and 16 mm end face and chamfering and inner hole phi 10 mm, M8-6 h of internal thread, phi 6 mm hole and 120 chamfer 2 mm groove.The two groups of processing surface has a certain position requirements, mainly:1. 32 mm hole and the phi phi and 16 mm center line of the vertical degree of tolerance of 0.10;2. 32 mm hole end face and phi phi 16 mm center distance of 12 mm.Known from the analysis of the above, for the two groups of processing and surface processing first in the first group, and processing the second group. By reference in the surface and hole machining accuracy of machine tool can achieve the location precision of knowable, the above technical requirements can be reached, parts molding process is feasible.According to parts material to determine the blank for gray cast iron, and query data by calculation, the blank weight about 0.72 kg. Type for medium and small batch production, can be used over a box of sand mold casting blank. Due to phi 32 mm hole needs to be forged, so you also need to put the core. In addition, to eliminate residual stress, casting should be arranged after artificial aging process.About promoting process steps and machine tool fixture design method of concrete in this paper. Process design is in learning technology of mechanical manufacturing technology and machine tool fixture design, on the basis of production practice, the integrated use of learned knowledge of parts for the design of machining process planning and machine tool fixture design, in accordance with the requirements of parts processing, the feasible process route and reasonable fixture scheme, to ensure parts processing quality.According to data shows, the push is shaper into small parts to the organization, its main role is to put the coming from the motor rotation by eccentric lever push around its axis swing, plucked a ratchet wheel at the same time, drive screw rotation, realize automatic feed of the workbench.
