汽缸式弹簧耐久试验装置Cylinder type spring durability test device机电工程学院 机械制造与自动化 陈义 Institute of electrical and mechanical engineering machinery manufacturing and automation Chen Yi摘要:根据EN61029-2-9：2002标准的要求，斜切锯的回复弹簧应能承受10000次的压缩与回复耐久试验，不会断裂并能保持正常的回复力。目前尚无一款专门针对回复弹簧的检测装置。本项目设计的一款汽缸式弹簧耐久的试验装置，该装置采用压缩空气为动力，具有安装位置与动作行程可调结构，适用于不同形状尺寸斜切锯回复弹簧耐久试验，构造简单，控制可靠，可实现无人值守工作，满足斜切锯回复弹簧耐久试验相关标准要求。Abstract: according to the EN61029-2-9: 2002 standard requirements, miter saw a return spring should be able to withstand 10000 times the compression and resilience durability test, not break and can maintain the normal recovery stress. There is a specific return spring detection device. The project design of a cylinder type spring durability test device, the device adopts the compressed air as a driving force, with the mounting position and the action journey adjustable structure, applicable to the different shape and size of a miter saw a return spring durability test, and has the advantages of simple structure, reliable control, can realize the unattended, meet the miter saw a return spring durability test standard requirement.关键词：斜切锯 回复弹簧 汽缸式 耐久性测试 可调机构 Key words: miter saw a return spring cylinder durability test of adjustable mechanisms引言Introduction斜切锯，主要功能是截断木材。可以切出40到90之间的角度，最常用的是45度角的切割。斜切锯切割精确些，截面更平整，操作更安全。当斜切锯完成切割，撤去下压外力时，应能自动从最大切割深度回复到停歇位置，如采用压缩弹簧回复，该弹簧应能承受10000次的压缩与回复耐久试验，不会断裂并能保持正常的回复力。出口到欧共体国家的斜切锯产品必须符合EN61029-2-9：2002标准要求， TüV、GS、GE等认证对斜切锯也有回复弹簧耐久试验项目要求，但目前我国尚无该项目成熟的检测设备。以往对弹簧耐久性测试，检测人员通常会把斜切锯回复弹簧拆卸，安装于专用弹簧试验机上进行检测，该方法的测试环境发生变化，不满足相关标准要求。汽缸式弹簧耐久试验装置是直接对斜切锯整机进行试验，不用拆卸弹簧，检测结果更加精准，符合相关标准。A miter saw, the main function is to cut wood. You can cut out 40 to 90 between the angle, the most commonly used is a 45 degree angle cutting. Miter saw cutting precisely, section smooth, safe operation. When the miter saw cutting away, under the pressure of external force, should be able to automatically from the maximum depth of cut back to the stop position, such as the use of compression spring back, the spring should be able to withstand a 10000 compression and recovery durability test, not break and can maintain the normal recovery stress. Exports to the EEC countries of the miter saw the product must accord with EN61029-2-9 : 2002 standard requirements, T V, GS, through the GE certification of the miter saw has a return spring durability test project requirements, but at present our country is the mature project testing equipment. The spring durability testing, testing personnel will usually miter saw a return spring removing, mounted on a special spring testing machine for the detection, the method of testing the environment changes, do not meet the standards. Cylinder type spring durability test device is directly to the miter saw machine test, without removing the spring, the detection result to be more accurate, in line with the relevant standards.
