Cylinder selection
1, the type of choice
According to the working requirements and conditions, select the type of cylinder. Request cylinder arrives at a stroke without terminal impact phenomenon and the impact noise should choose a buffer cylinder; light weight, light should require the installation of cylinder; space narrow and short stroke, optional thin cylinder; horizontal load, optional cylinder with rod; braking requirements of high precision, should lock cylinder; do not allow the piston rod rotation, optional a rod is not rotational cylinder; high temperature environment need to use heat-resistant cylinder; in a corrosive environment, selection of corrosion resistant cylinder. In the dust and other harsh environment, the need to install the end of the piston rod. Require no pollution when the need to use oil or oil-free lubrication cylinder.
2, installation form
According to the installation location, purpose of use and other factors. In general, the use of fixed cylinder. In the need to work with the continuous rotation (such as lathes, grinders, etc.), should be used to rotate the cylinder. When the piston rod is required to move in a straight line, the shaft pin type cylinder is also needed for the arc swing. Special cylinders should be selected when there are special requirements.
3, the size of the force
That is the choice of bore. According to the size of the load force to determine the output of the cylinder thrust and tension. Generally, according to the theory of external load balancing requirements of the cylinder force, according to different speeds to choose different load rates, so that the cylinder output force slightly margin. The bore is too small, the output power is not enough, but the diameter is too large, the heavy equipment, cost increase, and increase consumption, waste of energy. In the fixture design, should be used as far as possible the expansion mechanism, in order to reduce the cylinder size.

一、气缸的选择
一、气缸的选择
1、类型的选择
根据工作要求和条件,正确选择气缸的类型。要求气缸到达行程终端无冲击现象和撞击噪声应选择缓冲气缸;要求重量轻,应选轻型缸;要求安装空间窄且行程短,可选薄型缸;有横向负载,可选带导杆气缸;要求制动精度高,应选锁紧气缸;不允许活塞杆旋转,可选具有杆不回转功能气缸;高温环境下需选用耐热缸;在有腐蚀环境下,需选用耐腐蚀气缸。在有灰尘等恶劣环境下,需要活塞杆伸出端安装防尘罩。要求无污染时需要选用无给油或无油润滑气缸等。
2、安装形式
根据安装位置、使用目的等因素决定。在一般情况下,采用固定式气缸。在需要随工作机构连续回转时(如车床、磨床等),应选用回转气缸。在要求活塞杆除直线运动外,还需作圆弧摆动时,则选用轴销式气缸。有特殊要求时,应选择相应的特殊气缸。
3、作用力的大小
即缸径的选择。根据负载力的大小来确定气缸输出的推力和拉力。一般均按外载荷理论平衡条件所需气缸作用力,根据不同速度选择不同的负载率,使气缸输出力稍有余量。缸径过小,输出力不够,但缸径过大,使设备笨重,成本提高,又增加耗气量,浪费能源。在夹具设计时,应尽量采用扩力机构,以减小气缸的外形尺寸。
