The second step is to a renovation completed in the district under the jurisdiction of the street, the street is responsible for the implementation of professional management, the establishment of long-term management mechanism. Two remediation farmers market, the convenience of the market is mainly divided into three levels: the first level is to make an inventory of the stock market, we have a strange phenomenon, such as the Zibo road and Heze Road InterchangeSlaughter into the Milky way trade city, there are many shops booth is still empty, but small business hawker, in Wang Jia Cun cloth spreading their stalls, a waste of resources.

To temporarily really necessary to be retained as early as the night market, to 研究出了作为大规模生产的可更换部件的系统。至今还很活跃的惠特尼公司，早在19世纪四十年代就研制成功了一种转塔式六角车床。这种车床是随着工件制做的复杂化和精细化而问世的，在这种车床中，装有一个绞盘，各种需要的刀具都安装在绞盘上，这样，通过旋转固定工具的转塔，就可以把工具转到所需的位置上。随着电动机的发明，机床开始先采用电动机集中驱动，后又广泛使用单独电动机驱动。 二十世纪初，为了加工精度更高的工件、夹具和螺纹加工工具，相继创制出坐标镗床和螺纹磨床。同时为了适应汽车和轴承等工业大量生产的需要，又研制出各种自动机床、仿形机床、组合机床和自动生产线。1900年进入精密化时期19世纪末到20世纪初，单一的车床已逐渐演化出了铣床、刨床、磨床、钻床等等。 第二章 CA6140车床型号及解释 CA6140车床解释为: C:车床类代号 A:第一次设计修改 6:落地及卧式车床组代号 40:主参数折算值，回转直径为400毫米 第三章 机床的组成 (一)机床的组成 CA6140车床的主要组成部件如图所示。 term management mechanism.-stablishment of longthe e e district under the jurisdiction of the street, the street is responsible for the implementation of professional management,king, street lighting, security, property and other public infrastructure.

To this, to "pull" combined "cited stallsroad and Heze Road InterchangeSlaughter into the Milky way trade city, there are many shops booth is still empty, but small ban inventory of the stock market, we have a strange phenomenon, such as the Zibo Two remediation farmers market, the convenience of the market is mainly divided into three levels: the first level is to makepublic demand. To temporarily really necessary to be retained as early as the night market, tomeet au to take the lead, pay close attention to the planning and expansion, the new a batch of farmers market, convenience markets, eliminate market probe, stalls spillover, maintain market Clean and tidy; the third level is by the Municipal Housing Burenorm neatly, live poultry fish according to the requirements, the construction of sewer system, to ensure that operators operating- 5 - CA6140车床外形图 1-主轴箱;2-刀架;3-尾座;4-床身;5、9-床腿; 6-光杠;7-丝杠;8-溜板箱;10-进给箱;11-挂轮 CA6140型卧式车床主要结构 (一)主轴箱 CA6140车床的主轴箱包括:箱体、主轴部件、传动机构、操纵机构、换向装置、制动装置和润滑装置等。其功用在于支承主轴和传动其旋转，并使其实现起动、停止、变速和换向等。 机床的主轴箱是一个比较复杂的运动部件，它的装配图包括展开图、各种向视图和剖面图，以表示出主轴箱的所有零件及其装配关系。 1、主轴部件 主轴部件是主轴箱最重要的部分，由主轴、主轴轴承和主轴上的传动件、密封件等组成。 主轴前端可安装卡盘，用以夹持工件，并由其带动旋转。主轴的旋转精度、刚度和抗振性等对工件的加工精度和表面粗糙度有直接影响，因此对主轴部件的要求较高。 CA6140型车床的主轴是一个空心阶梯轴。其内孔是用于通过棒料或卸下顶尖时所用的铁棒，也可用于通过气动、液压或电动夹紧驱动装置的传动杆。主轴前端有精密的莫氏6号锥孔，用来安装顶尖或心轴，利用锥面配合的摩擦力直接带动心轴和工件转动。主轴后端的锥孔是工艺孔。 CA6140型卧式车床的主轴部件在结构上做了较大改进，由原来的三支承结构改为两支承结构;由前端轴向定位改为后端轴向定位。前轴承为P级精度的双列短圆柱滚子轴承，用于承受径向力。后轴承为一个推力球轴承和角接触球轴承，分别用于承受轴向力和径向力。 主轴的轴承的润滑都是由润滑油泵供油，润滑油通过进油孔对轴承进行充分润滑，并带走轴承运转所产生的热量。为了避免漏油，前后轴承均采用了油沟式密封装置。主轴旋转时，依靠离心力的作用，把经过轴承向外流出的润滑油甩到轴承端盖的接油槽里，然后经回油孔流回主轴箱。 主轴上装有三个齿轮，前端处为斜齿圆柱齿轮，可使主轴传动平稳，传动时齿轮作用在主轴上的轴向力与进给力方向相反，因此可减少主轴前支承所承受的轴向力。 主轴前端安装卡盘、拨盘或其它夹具的部分有多种结构形式。 2、开停和换向装置 CA6140型卧式车床采用的双向多片式摩擦离合器实现主轴的开停和换vegetation, trimming damaged roads, add necessary garbage box, parking, street lighting, security, property and other public infrastructure. The second step is to a renovation completed in the district under the jurisdiction of the street, the street is responsible for the implementation of professional management, the establishment of long-term management mechanism. Two remediation farmers market, the convenience of the market is mainly divided into three levels: the first level is to make an inventory of the stock market, we have a strange phenomenon, such as the Zibo road and Heze Road InterchangeSlaughter into the Milky way trade city, there are many shops booth is still empty, but small business hawker, in Wang Jia Cun cloth spreading their stalls, a waste of resources. To this, to "pull" combined "cited stalls Burglary", "cited Tanru city". The second level is the existing free market of agricultural products, convenience market to upgrade and standardize the unified standard, set up by the industry and commerce, food and drug, health, public security and other departments personnel market management office, strengthen the daily management, so that the paddle to the city, the stalls placed neatly, live poultry fish according to the requirements, the construction of sewer system, to ensure that operators operating norms, eliminate market probe, stalls spillover, maintain market Clean and tidy; the third level is by the Municipal Housing Bureau to take the lead, pay close attention to the planning and expansion, the new a batch of farmers market, convenience market meet public demand. To temporarily really necessary to be retained as early as the night market, to 向。 其由结构相同的左右两部分组成，左离合器传动主轴正转，右离合器传动主轴反转。摩擦片有内外之分，且相间安装。如果将内外摩擦片压紧，产生摩擦力，轴I的运动就通过内外摩擦片而带动空套齿轮旋转;反之，如果松开，轴I的运动与空套齿轮的运动不相干，内外磨擦片之间处于打滑状态。正转用于切削，需传递的扭矩较大，而反转主要用于退刀，所以左离合器摩擦片数较多，而右离合器摩擦片数较少。 内外摩擦片之间的间隙大小应适当:如果间隙过大，则压不紧，摩擦片打滑，车床动力就显得不足，工作时易产生闷车现象，且摩擦片易磨损。反之，如果间隙过小，起动时费力;停车或换向时，摩擦片又不易脱开，严重时会导致摩擦片被烧坏。同时，由此也可看出，摩擦 离合器除了可传递动力外，还能起过载保险的作用。当机床超载时，摩擦片会打滑，于是主轴就停止转动，从而避免损坏机床。所以摩擦片间的压紧力是根据离合器应传递的额定扭矩来确定的，并可用拧在压套上的螺母9a和9b来调整。 3、制动装置 制动装置功用在于车床停车过程中克服主轴箱中各运动件的惯性，使主轴迅速停止转动，以缩短辅助时间。CA6140型卧式车床采用闸带式制动器实现制动。 制动带6的拉紧程度可由螺钉5进行调整。其调整合适的状态，应是停车时主轴能迅速停止，而开车时制动带能完全松开。 (二)溜板箱 溜板箱的功用是:将丝杠或光杠传来的旋转运动转变为直线运动并带动刀架进给;控制刀架运动的接通、断开和换向;机床过载时控制刀架停止进给;手动操纵刀架移动和实现快速移动。 因此，溜板箱通常设有以下几种机构: 接通丝杠传动的开合螺母机构; 将光杠的运动传至纵向齿轮齿条和横向进给丝杠的传动机构; 接通、断开和转换纵、横向进给的转换机构; 保证机床工作安全的过载保险装置和互锁机构; 控制刀架运动的操纵机构; 改变纵、横向机动进给运动方向的换向机构; 快速空行程传动机构。 1、纵横向进给操纵机构 term management mechanism.-stablishment of longthe e e district under the jurisdiction of the street, the street is responsible for the implementation of professional management,king, street lighting, security, property and other public infrastructure.
