线圈铁芯加工工艺及钻攻2-M3深6螺纹孔夹具设计
摘要
课程设计是每一位大学在校生的必修课程。本次设计是在指导老师提供的零件图纸的基础上进行的。
本文设计给定的零件是线圈铁芯，线圈铁芯是增强内部插有铁芯的螺线管，当通电螺线管插入铁芯后，由于铁芯被磁化产生了与圆螺线管方向一致的磁场，因而其磁性比原来要增强许多。因此，对线圈铁芯的研究是非常有意义的。本次设计的任务是设计加工工艺、钻攻2-M3深6螺纹孔专用夹具。在充分了解零件的结构后，对其毛坯尺寸、制造类型、基准、加工的工艺路线进行了确定；然后依据设计的加工工艺路线，对每一个工序进行计算。
本次设计出的专用钻床夹具，在减少停机时间的同时，还提高生产效率。在进行该专用夹具设计的时候，首先应该是建立在对零件的工艺进行分析、选择粗精基准、进行必要计算的基础上。该夹具在设计之初就注重结构工艺性，所以本次设计的夹具结构简易、紧凑，操作起来也比较方便灵活。更重要的是它在提高生产效率方面所起的作用尤为突出，体现了这次设计的主旨。

Abstract
Curriculum design is a compulsory course for every university student. This design is carried out on the basis of the parts drawing provided by the instructor.
In this paper, a given part is a coil iron core. The coil iron core is a solenoidwith an iron core inserted in it. When the electrified solenoid is inserted into the iron core, the magnetic field in the direction of the circular solenoid is produced due to the magnetization of the iron core, so its magnetism is much stronger than the original one. Therefore, the study of coil core isvery meaningful. The task of this design is to design processing technology, drill and attack 2-M3 deep 6 thread hole special fixture. After fully understanding the structure of the parts, the blank size, manufacturing type, benchmark, processing technology route are determined, and then according to the design of the processing technology route, each process is calculated.
The special drill jig designed this time reduces production downtime and improves production efficiency. In the design of this special fixture, the first step should be based on the analysis of the process of the parts, the selection of rough and fine benchmarks, and the necessary calculation. The fixture in the design of the early attention to structural technology, so the design of the fixture structure is simple, compact, more convenient and flexible to operate. More importantly, it has played a particularly prominent role in improving production efficiency, reflecting the main purpose of this design.
Keywords coil core, processing technology, drill attack 2-M3 depth 6, threaded hole, fixture
