技术领域technical field
本实用新型涉及机械加工技术领域，更具体的说，尤其涉及一种杆状工件单端旋转装夹装置。The utility model relates to the technical field of machining, in particular to a single-end rotary clamping device for a rod-shaped workpiece.
背景技术Background technique
杆状工件是指纵向尺寸比横向尺寸要大得多的构件，例如汽车的轴类零件、各种导杆、支撑杆等。杆件在加工时往往需要对杆件的单端进行加工，这就需要对杆状工件的另一端进行装夹。在需要对杆状工件的装夹端进行装夹和旋转定位同时进行时，通常采用的方法是采用卡盘或者气爪抓紧杆状工件的装夹端，同时卡盘或气爪连接转轴，转轴穿过卡盘或气爪的安装座连接驱动转轴转动的伺服电机，由伺服电机带动转轴的转动进而带动气爪或卡盘的转动。这种装夹方式对于转动行程较短的装置，仅适用于旋转角度在360度以内的杆状工件的加工，其转动时需要伺服电机时而正转，时而反转，其控制精度要求较高，且由于伺服电机的反复正反转不仅损害伺服电机的使用寿命，而且降低了需要连续多位置加工时的旋转效率。Rod-shaped workpieces refer to components whose longitudinal dimension is much larger than the transverse dimension, such as axle parts of automobiles, various guide rods, support rods, etc. When processing rods, it is often necessary to process one end of the rod, which requires clamping the other end of the rod-shaped workpiece. When it is necessary to clamp and rotate the clamping end of the rod-shaped workpiece at the same time, the usual method is to use a chuck or air claw to grasp the clamping end of the rod-shaped workpiece, and at the same time, the chuck or air claw is connected to the rotating shaft, and the rotating shaft The mounting seat of the chuck or the air claw is connected to the servo motor that drives the rotating shaft to rotate, and the servo motor drives the rotation of the rotating shaft to drive the rotation of the air claw or the chuck. This clamping method is only suitable for the processing of rod-shaped workpieces with a rotation angle within 360 degrees for devices with a short rotation stroke. When rotating, the servo motor is required to rotate forward and reverse sometimes, and its control accuracy is high. Moreover, the repeated positive and negative rotation of the servo motor not only damages the service life of the servo motor, but also reduces the rotation efficiency when continuous multi-position processing is required.
杆状工件的种类多样，由此带来的杆状工件的装夹端也是多样的，对于各种不同的杆状工件，尚无一种可以一台设备即可对应多种不同种类杆状工件装夹和旋转的装置。There are various types of rod-shaped workpieces, and the resulting clamping ends of rod-shaped workpieces are also diverse. For various rod-shaped workpieces, there is no one device that can correspond to many different types of rod-shaped workpieces. Clamping and rotating device.
