Abstract: The transformation of ordinary
machine tools are CNC machining of small and
medium enterprises to improve the accuracy of a
way to reduce the auxiliary processing time is
now shorter processing time is a major means of
automatic rotary tool holder so the transformation
is the main part of NC.
Keywords: CNC turret rotation transformation of the Hall element
1 Introduction
Machine is the basis of equipment manufacturing industry, which directly affects the level of technology manufacturing industry. Currently, the processing center as the representative of the NC machine tool commonly used by developed countries has become a modern industrial manufacturing plant processing unit. From the development of general machine tools to CNC machine tools, machine tool structure in the transmission and a leap forward with this adaptation, CNC machine tools in its structural design will surely require new design
methods and theories to guide.
China as a developing country, the CNC machine tools are expensive, some SMEs unable to acquire CNC machine, so the general transformation of NC machine tools is a better and more economical way, a CK6140 needs
funds 115,000, while the CA6140 CNC Lathe 2.7
million renovation needs.
Machine tool holder is one of the main components, but also one of the objects need to transform NC. Turret accuracy, rigidity and reliability of a direct impact on machine performance, in the deadly machine analysis, the deadly turret is the highest degree, digital control
system to issue commands, the turret does not turn position, knife switch bit errors, misplaced turret, turret alarm, turret tool change and a series of failures can not be normal so that the machine
will not work properly. This paper briefly describes
the economic CA6140 Machine Tool CNC turret
part of the transformation of the transformation of design.
The need for reform knife, according to the modified object to determine the main processing
machine. If using a knife to complete the processing on this machine, there is no need to transform the knife. For multi-knife, such as lathe modified take three or four knives to complete all the sewing process, we must transform the turret
components. That removed the original manual
turret, fitted with electric or hydraulic drive
controlled by the numerical control device of
automatic knife.
Turret lathe is mainly used for holding the cutting tool used, so a direct impact on the structure function of the cutting lathe and cutting efficiency, according to the type of machine tool holder, properties and use the occasion of the comprehensive comparison, the specific use by
the Changzhou Wang of CNC equipment factory
production LD4-CK6140 four-station automatic rotary tool holder. The turret has shifted fast, high positioning accuracy, the advantages of tangential torque, sending translocation by the Hall element, long life. Rotating turret with automatic replacement of ordinary knife, remove the original turret and small slide plate, put
LD4-CK6140 electric knife.
2, the turret control design
2.1 The process of tool change
Rotating turret tool change, the first cutter release (lift), cutter knife near translocation arrived at the designated position, the last cutter reset (drop) clamping. When the control 2011 Second International Conference on Digital Manufacturing & Automation

Development of a high-performance laser-guided deep-holeboring tool: optimal
determination of reference origin for precise guiding
Abstract
A laser-guided deep-hole boring tool using piezoelectric actuators was developed to prevent
hole deviation. To extend the depth o controll able boring further, the following were improved.
The tool’s guiding error, caused by misalignment of the corner cube prism and the mirror in the
optical head from the spindle axis, was eliminated using an adjustment jig that determined the
reference origins of the two position-sensitive detectors (PSDs) precisely. A single-edge
counter-boring head is used instead of the double-edge head used up to now The former was
thought to be better in attitude control than the latter. A new boring bar, which was lower in
rigidity and better in Controllability of tool attitude, was used. Experiments were conducted to

1.1 Modern Packaging
Author：
Abstract
1. Changing Needs and New Roles
Looking back, historical changes are understandable and obvious. That all
of them have had an impact on the way products are brought, consumed and
packaged is also obvious. What is not so obvious is what tomorrow will
bring. Yet, it is to the needs, markets, and conditions of tomorrow that
packaging professionals must always turn their attention.
The forces that drove packaging during the Industry Revolution continue
to operate today. The consumer society continues to grow and is possibly
best described by a 1988s bumper sticker, “Born to Shop”. We consume
goods today at a rate 4 to 5 times greater than we did as recently as 1935.
Most of these goods are not essential to survival; they constitute what
we may call “the good life”.

The Reciprocating Engine
My Internet research eventually led me to the American Stirling
Company．While cruising their website for engine kits I ran across，an ad
that said they wanted a technical writer who would trade some writing
of instructional material and plans for engine kits．I shot them a quick
email．I am a technical writer in my day job，and I write instructional
material for computer software．Now that I was designing my own
Stirling engines，I thought I would be a perfect match for them!Well，I
didn’t end up working for them，but after a
few conversations with the owner of the company I was on a mission to
complete my quest for a hand built LTD Stirling engine，and I was going
to write a book about it at the same time．

Drive axle
All vehicles have some type of drive axle/differential assembly
incorporated into the driveline. Whether it is front, rear or four wheel drive,
differentials are necessary for the smooth application of engine power to
the road.
Powerflow
The drive axle must transmit power through a 90 angle. The°flow of
power in conventional front engine/rear wheel drive vehicles moves from
the engine to the drive axle in approximately a straight line. However, at
the drive axle, the power must be turned at right angles (from the line of
the driveshaft) and directed to the drive wheels.
This is accomplished by a pinion drive gear, which turns a circular
ring gear. The ring gear is attached to a differential housing, containing a
set of smaller gears that are splined to the inner end of each axle shaft. As

Link mechanism
Linkages include garage door mechanisms, car wiper mechanisms, gear shift
mechanisms. They are a very important part of mechanical engineering which is
given very little attention...
A link is defined as a rigid body having two or more pairing elements which
connect it to other bodies for the purpose of transmitting force or motion . In every
machine, at least one link either occupies a fixed position relative to the earth or
carries the machine as a whole along with it during motion. This link is the frame
of the machine and is called the fixed link.
An arrangement based on components connected by rotary or sliding interfaces only
is called a linkage. These type of connections, revolute and prismatic, are called
lower pairs. Higher pairs are based on point line or curve interfaces.

机械设计
摘要： 机器是由机械装置和其它组件组成的。它是一种用来转换或传递能量的装置，例如：发动机、涡轮机、车辆、起重机、印刷机、洗衣机、照相机和摄影机等。许多原则和设计方法不但适用于机器的设计，也适用于非机器的设计。术语中的“机械装置设计” 的含义要比“机械设计”的含义更为广泛一些，机械装置设计包括机械设计。在分析运动及设计结构时，要把产品外型以及以后的保养也要考虑在机械设计中。在机械工程领域中，以及其它工程领域中，所有这些都需要机械设备，比如：开关、凸轮、阀门、船舶以及搅拌机等。
关键词： 设计流程 设计规则 机械设计
设计流程
设计开始之前就要想到机器的实际性，现存的机器需要在耐用性、效率、重量、速度，或者成本上得到改善。新的机器必需具有以前机器所能执行的功能。
在设计的初始阶段，应该允许设计人员充分发挥创造性，不要受到任何约束。即使产生了许多不切实际的想法，也会在设计的早期，即在绘制图纸之前被改正掉。只有这样，才不致于阻断创新的思路。通常,还要提出几套设计方案，然后加以比较。很有可能在这个计划最后决定中,使用了某些不在计划之内的一些设想。
一般的当外型特点和组件部分的尺寸特点分析得透彻时，就可以全面的设计和分析。接着还要客观的分析机器性能的优越性，以及它的安全、重量、耐用性，并且竞争力的成本也要考虑在分析结果之内。每一个至关重要的部分要优化它的比例和尺寸，同时也要保持与其它组成部分相协调。
也要选择原材料和处理原材料的方法。通过力学原理来分析和实现这些重要的特性，如那些静态反应的能量和摩擦力的最佳利用，像动力惯性、加速动力和能量；包括弹性材料的强度、应力和刚度等材料的物理特性，以及流体润滑和驱动器的流体力学。设计的过程是重复和合作的过程，无论是正式或非正式的进行，对设计者来说每个阶段都很重要。 最后，以图样为设计的标准，并建立将来的模型。如果它的测试是符合事先要求的，则再将对初步设计进行某些修改，使它能够在制造成本上有所降低。产品的设计需要不断探索和发展。许多方案必须被研究、试验、完善，然后决定使用还是放弃。虽然每个工程学问题的内容是独特的，但是设计师可以按照类似的步骤来解决问题。
