差动滚齿机广泛应用于滚齿机、滚齿机、滚齿机和齿轮加工方法中。渐开线齿轮的优点已成为齿轮传动中应用***广泛的齿轮。渐开线齿轮的应用***为广泛，渐开南京SKF轴承线齿轮的加工方法是仿形加工。
Differential gear hobbing machine is widely used in hobbing machine, hobbing machine, hobbing machine and gear processing method. The advantages of involute gear h***e become the most widely used gear in gear tran***ission. Involute gear is the most widely used. The machining method of involute Nanjing SKF bearing line gear is copying machining.
经过多年的发展历史，其作用大致经历了三个阶段：***阶段，在生产过程中，工件夹具是基本的夹紧装置，起到工件固定卡的基本作用。随着南京SKF轴承内燃机和汽车工业在军事生产中的发展，生产技术和夹具逐渐发挥高功率和稳定加工质量的优势，越来越多的工程设备和夹具被***。矿石是***的。这是夹具开发的第二阶段。在此期间，夹具开发的主要特点是高功率。
After many years of development history, its role has roughly gone through three stages: the first stage, in the production process, the workpiece fixture is the basic clamping device, plays the basic role of the workpiece fixed card. With the development of Nanjing SKF bearing internal combustion engine and automobile industry in military production, production technology and fixture gradually play the advantages of high power and stable processing quality, more and more engineering equipment and fixture are positioned. The ore is perfect. This is the second stage of fixture development. During this period, the main feature of fixture development is high power.
随着电子技术和数控技术的发展，现代夹具的自动化和适应性不断提高，夹具与机械一体化逐渐发展。因此，大量的小批量生产能力已逐步发展到***化生产水平。这是夹具开发的第三个阶段。在此期间，夹具的主要特点是精度高、适应性强。可以预见，不同时期夹具开发的主要趋势是循序渐进和智能化。主要夹具具有以下功能：
With the development of electronic technology and numerical control technology, the automation and adaptability of modern fixture are c***tantly improving, and the integration of fixture and machinery is gradually developing. Therefore, a large number of ***all batch production capacity has gradually developed to the level of specialized production. This is the third stage of fixture development. During this period, the main features of the fixture are high accuracy and adaptability. It can be predicted that the main trend of fixture development in different periods is gradual and intelligent. The main fixture has the following functi***:
（a）保证南京SKF轴承夹具的加工精度，夹紧工件，准确确定工件与刀具与机床相对位置的接触，从而保证加工精度。
(a) To ensure the machining accuracy of the Nanjing SKF bearing fixture, clamp the workpiece, and accurately determine the contact between the workpiece and the relative position of the tool and the machine tool, thus ensuring the machining accuracy.
（b）渐进式生产动力、机床和夹具可以快速***和夹紧工件，减少辅助时间，并提高生产能力。
(b) Progressive production power, machine tools and fixtures can quickly locate and clamp workpieces, reduce ancillary time, and increase production capacity.
（c）为了减少劳动强度，使用南京SKF轴承机械、气动和液压夹紧装置来降低机床和夹具的劳动强度。
(c) To reduce labor intensity, Nanjing SKF bearing mechanical, pneumatic and hydraulic clamping devices are used to reduce the labor intensity of machine tools and fixtures.
（d）扩大机床和夹具的使用范围。以机床加工技术的规模、规模和扩展器为例，采用镗孔法代替镗床或钻床、镗床和镗床。Jigger。比例夹具
(d) expand the scope of use of machine tools and fixtures. Taking the scale, scale and expander of machine tool processing technology as an example, boring method is used instead of boring machine or drilling machine, boring machine and boring machine. Jigger. Proportional fixture
（E）通用南京SKF轴承分类器是具有大夹具的标准结构，如三爪卡盘和四爪夹具，以及顶部夹紧和分度米尔斯。
(E) The general Nanjing SKF bearing classifier is a standard structure with large fixtures, such as three-jaw chucks and four-jaw fixtures, as well as top clamping and indexing Mills.
（f）专用机床夹具专用机床夹具是工件夹具的特殊工艺设计。专用机床夹具适用于货物相对稳定、产值大的场合。
(f) special machine tool jig for special machine tool jig is special process design for workpiece fixture. Special machine tool fixture is suitable for occasi*** where goods are relatively stable and output value is large.
（g）装配一套具有预先标准化部件和部件的组合夹具。
(g) assemble a set of modular fixture with pre standardized parts and components.
