液压缸设计综合实训报告书

videoconference, Secretary of the provincial Committee of Xia Baolong stressed: this year is the five water treatment 357 timetables for three years to resolve outstanding issues, obviously worked, victory of the year. The Countys departments at all levels must firmly establish the guanghui is gold and silver green development concept, convinced that Castle is not relaxed, always maintaining strategic ability and strong determination to improve the environment, consistently playing well five water treatment of winning the war, ever-higher levels of comprehensive well-off society was built. (A) lay the sewage uphill battle. This year we will river water quality improved at the county level, up to five this basic objective grasp of pollution control that focus, with the focus on three things: a good job, clear rivers reaching the County created. Organization look back special inspection, the County garbage River, black and odorous River is Dragnet investigation, timely rectification of problems found in place firmly to prevent river pollution rebound. In accordance with the one-stop strategy, improving the inferior five water quality monitoring stations work this year to ensure the Elimination of 1 provincial control, five water quality section 3 municipalities controlled deterioration, ensure the creation this year of clear rivers standards. Second, pay special attention to pollution-cutting construction of nanotubes. Intercepting nanotubes are the basis of pollution of water source engineering, engineering, matter of success or failure of water management. Urban sewage treatment, to improve effluent from sewage treatment rate, running accuracy, compliance requirement, speed up the towns support network construction, is focusing on nanotubes home last meters question. Domestic sewage treatment in rural areas, this year is the final year of the three-year action, determination to fight and the momentum around, ending the battle on which fully to ensure the realization of all County 648 formed village coverage. Also, be sure to attach importance to focus on rural domestic wastewater treatment facility operation and management, ensure that wastewater treatment facility up and running, role play, avoid the Sun problem. Third, pay special attention to the River Lake pond desilting operation. Provinces now have focused on pollution control of water go to dig up mud, as the deepening water of this years plays. Next, to jump-start an investigation line touches work, implementation plan according to the priorities and the programme of work, in accordance with the one river one policy requires detailed cleaning, dredging plan, planning ahead of time cleaning out mud way out, according to local conditions to do sludge, promote scientific resource utilization of silt and mud. (B) the heavy regulation of heavily polluting industries. Pollution of water must grab the source, wastewater is primarily the source of backward production capacity, increase the intensity of红色字体为自己修改部分 综合训练报告书题 目 液压缸设计与制造 学院 机械设计制造及其自动化 专业 班学生姓名 学号 .指导教师 .完成日期 2012年12月21日 .湖南工程学院二一二年十二月湖南工程学院综合训练任务书 设计题目： 液压缸设计与制造 姓名 专业 机械设计制造及其自动化 班级 班 学号 指导老师 教研室主任 一、训练目的机械产品设计制造综合训练是专业教学计划中规定的重要实践教学环节，通过完成指定产品或机械装置的设计制造过程，巩固和深化学生综合运用所学机械设计、制造工艺及CAD/CAM技术等方面的基础理论、基本知识和基本技能，较全面地获得机械产品的生产实际知识和综合应用能力，以培养具备现代机械设计制造技术基础知识与应用能力，具有较强的工程实践能力和创新能力的应用型工程师。二、训练任务在三周时间内完成指定产品（机械装置）的设计、零件加工及装配。2.1 指定产品（机械装置）的设计1）产品功能分析及结构设计2）零件设计2.2 零件制造工艺设计1）机械加工工艺过程卡2）机械加工工序卡3）复杂零件数控编程（备选）2.3 加工制造2.4 检验分析2.5 产品装配 2.6 综合训练说明书三、训练要求1）进行产品的结构设计，运用CAD技术完成零件三维建模和产品装配建模。2）绘制指定零件的工程图，按国标正确标注尺寸、形位公差及技术要求。3）对零件进行正确的工艺分析，按指定的格式填写加工工艺文件。分析产品零件图样，确定毛坯，拟订工艺路线，选择设备及工艺装备。根据机械加工工艺卡片，确定各工序的加工余量，计算工序尺寸及公差，详细地说明整个零件各个工序的要求。4）进行复杂零件的刀具路径与指定数控系统的数控程序生成。编制零件的加工工序卡，填写加工程序单，填写刀具调整单。5）完成零件加工制造。按照制定工艺文件，在老师指导下，遵守机床设备操作规程，独立调整、操作相应机床，进行零件加工。6）零件加工质量检测。正确地选用检验方法及计量器具，对零件进行质量检测和分析。7）产品装配。根据结构设计要求，正确装配。8）撰写综合训练说明书（上交电子稿和打印稿）。说明书应涵盖整个训练内容，字数不少于3.5千字。9）加工制造过程必须做好安全防范工作。四、成绩评定成绩评定是对学生在实训过程的能力、态度表现情况综合给出成绩，具体考核包括以下内容：1）机械设计能力。包括结构设计正确、合理性，工程图质量，工艺参数选定等。（20分）2）CAD技术应用能力。利用CAD/CAM 软件系统完成设计、编程情况，包括零部件的设计和造型、自动编程的刀位文件和 NC 程序。（15分）3）实际加工操作水平，所完成的零件质量以及装配质量。（40分）4）综合训练报告。（15分）5）平时成绩。（10分）目 录课程设计任务书I0前言11. 液压缸的设计21.1参数设计21.2选择材料21.3液压缸的结构设计71.4液压缸的精度设计91.5 液压缸的零件设计101.5.1 活塞杆的结构设计101.5.2 活塞杆的精度设计112. 液压缸的建模 122.1 活塞杆的建模132.2减速箱装配153. 活塞杆的工艺设计163.1 活塞杆的加工工艺分析173.1.1 毛坯的选择183.1.2工艺分析193.1.3机床的选择213.2 确定XX轴加工工艺路线223.3 工艺过程卡233.4加工工序卡244.

According to municipal, and municipal government deployment of seven big heavy pollution industry regulation three years action plans, requirements to December 2016 end of Qian, all included shut stopped eliminated of enterprise all shut stopped eliminated in place; June 30, 2017 Qian, all included place regulation upgrade and agglomeration restructuring of enterprise by unified standard regulation in place, late not standard of enterprise are implementation discontinued; June 30, 2018 Qian, all intends Park production of enterprise relocation Park in place, late not Park of are discontinued. In the process of renovation, will focus on four aspects: to firmly close the high energy consumption and heavy pollution, hopeless enterprise governance and production lines, eliminated a number of yearly emission intensity, low value-added products of backward production capacity. Second, we must strictly enforce the space, total project Trinity environment access system, promoting industry access and environmental conditions of access of enterprises to the Park, industrial park, in principle, no longer the class on the new project. Thirdly, promoting replacement and reconstruction of heavily polluting industries, mergers and reorganizations, guide enterprises to energy conservation, recycling and low-carbon and clean production, and improve the level of green development. Four to establish a long-term supervision mechanism, increase the intensity of special inspections, investigate and punish the rectification is not in place, normal business of running anti-pollution installations do not. (Iii) linkage to promote flood control water, drainage, water supply, improving water saving. Speed up cross Yang support river dike reinforcement, and along Pu seawall except insurance reinforcement, and Lake Qian sluice, and BA Cao sluice, and cloud cover reservoir, focus flood control drainage engineering construction, vigorously implementation strong library solid di spread row engineering, increased geological disaster hidden points governance efforts, solid advance small basin torrent disaster governance, efforts from essentially solution basin sex, and regional flood control drainage capacity insufficient of problem. Vigorously implement the piers, algae and other water sources protection and, promoting rural drinking water safety projects, setting up water pricing reform and environmental protection mechanism, guiding water depth. Further soil pollution and repair, strengthen agricultural non-point source pollution prevention, mountain, water, forests, fields, lakes, various elements mutual long. Four, manage to tighten control, to play three to split battle. Xia Baolong, Secretary of provincial party Committee stressed that while the three to split operation time is over three years, but three to split must continue to catch on, and resolve a split cannot be changed.
