基于三维设计的浮动式制动卡钳的车床夹具的研制(中文3600字,英文2000字)
摘要：根据制动卡钳在生产过程中的技术要求，本文研究的是一个基于三维设计的浮动式制动卡钳的专用夹具。根据专用夹具的三维建模和运动仿真的开发过程和验证数据显示，三维设计过程可以在原型建模之前方便的预测夹具的组装干涉和准确添加在铅砖的质量。通过这种方式，可以消除由摆动引起的车床夹具的不平衡和改善在缸孔与机床主轴的跳动公差精度，因此制动卡钳的缸孔加工质量可以很大程度的被保证。

Abstract：According to the technique requests of the brake caliper in the process of production, a special fixture of float brake caliper has been developed based on 3D design in this paper. The development process and verified data from 3D modeling and kinematics simulation for this special fixture show that this 3D-designed process can conveniently forecast the assembly interference of the fixture and accurately add the mass of lead brick before the prototype is made. In this way the flutter caused by the unbalanced lathe fixture can be eliminated and the precision of run-out tolerance in cylinder hole compared with machine tool spindle can be improved, thus the processing quality of the cylinder hole in a brake caliper can be greatly guaranteed.
