摘要
夹具是一种工件,一般用来定位和夹紧加工对象,使其处于行之有效的位置,从而对施工与检验产生有效的帮助。在机械设计制造的过程中,夹具的存在能够极大程度上提高产品的质量,因此,夹具被广泛的使用。在机械制造与设计的过程中,夹具设计一直都是重中之重。因为在整个过程中,夹具不仅仅用来对加工零件进行定位与夹紧,还能够确保其成形结构,并在一定程度上提高其精度。在整个机械制造的过程中,夹具也能够提高加工零件的生产效率。
    本次的毕业设计主要目的是对塔头片进行定位与夹紧工序中所采用的夹具进行设计。在对夹具设计的过程有了初步的理会特别是对塔头片夹具的认识更加深入后,分析塔头片制造工艺,制定塔头片夹具设计的总体方案。首先设计定位方案,对塔头片进行一番研究之后,采用底架与多定位销的定位,再设计夹紧机构,采用垂直夹紧机构。本文旨在采用塔式起重机塔头夹具来代替复杂的焊接操作来减轻工作量,提高生产效率及提升产品质量和生产效率。

ABSTRACT
Fixture is a kind of workpiece, generally used to locate and clamp the processing object, so that it is in an effective position, so that the construction and inspection have an effective help. In the process of mechanical design and manufacturing, the existence of fixtures can greatly improve the quality of the product, so the fixture is widely used. In the process of mechanical manufacturing and design, fixture design has always been the most important. Because in the whole process, the fixture is not only used to locate and clamp the machined parts, but also to ensure its forming structure and to improve its accuracy to a certain extent. Through the entire machinery manufacturing process, the fixture can also improve the efficiency of processing parts.
The main purpose of this graduation project is to design the fixture for positioning and clamping the tower head. In the process of the design of the fixture has a preliminary understanding, especially on the tower head fixture awareness more in-depth, the analysis of the tower head manufacturing process, the development of the tower head fixture design of the overall program. First, the design of the positioning program, the tower of the film after some research, the use of chassis and multi-positioning pin positioning, and then design clamping mechanism, the use of vertical clamping mechanism. The purpose of this paper is to use the tower crane fixture to replace the complex welding operation to reduce the workload, improve production efficiency and improve product quality and production efficiency.
