Abstract
Machining manufacturing is a basic discipline of mechanical specialty, which is widely used in practice.
This design is aimed atthe design of the manufacturing process flow of the bearing seat of the part, and the special fixture design for this part. This paper introduces the whole processing process of this part product in detail. Through analyzing the technical requirements of the part, the degree of processing required for each machining surface is determined, the processing process scheme is reasonably determined, and the process card and process card of machining process are formulated. The special fixture is designed for two main processes.
According to the existing condition, in the process of technological design in the traditional mechanical processing, process planning formulation needs according to the characteristics and the structure of the parts are processed performance requirements, and then according to the reality of the conventional processing route to carry on the processing and manufacturing, so that better product quality and technical performance to ensure that the parts, but also embodies the parts processing characteristics of the product.
In addition, in the design of special jig, special jig that conforms to the actual processing conditions is adopted for the main processes, which saves the processing time and improves the labor efficiency. Although the cost of processing is slightly increased, it is more conducive to the replacement and maintenance of the jig later and increases the utilization rate of materials.

Chapter 1 process analysis of parts
1.1 Part action and structure
1.1.1 function of parts
This part is the bearing seat. The bearing seat is usually installed on a machine tool. The corresponding connecting hole of the bearing seat is connected with the corresponding connecting screw rod or connecting shaft.
1.1.2 structural features of parts
From the perspective of shape, this part is relatively standard. The main part structure includes the main processing features of the large hole in the center, and the processing features to be carried out by two side planes.
1.2 key surface technical requirements for parts
To processing some of the surface of the bearing parts, mainly including its face and wide groove on the surface of the upper and the lower right side of the face and on the lower right side end face of wide groove, on his men along the surface and the lower left along the surface, phi before and after the end of 250, the surface characteristics of phi 250 before and after the end of the surface roughness request for Ra6.3, two parts of 50 h11 require wide groove is also Ra6.3, in addition to the rest of the state that the surface roughness of the requirements are Ra12.5 did not indicate the surface roughness were not processed.
The characteristics of the hole include that the large circular hole on the central datum is generally 180H7, the surface roughness of the hole is required to be Ra1.6, the
