The results show that it is technically feasible to apply the turning fixture and the feeding device of the pump rod joint to the pump rod joint production. In the actual production process, one person can control many lathes to realize the production and the whole system also demonstrates excellent and safe performance in the operation process.

结果表明，抽油杆接箍车削上料装置用于抽油杆接箍生产在技术上是可行的，在实际生产过程中可以实现一人控制多台机床进行生产，整套系统在运行过程中也表现出极好的运行性能和安全性能。

Providing the specific problems which enterprises encounter in their actual production processes, the problems in the development of enterprises are effectively resolved. Therefore it is essential to introduce latest technologies. The turning fixture and the feeding device of the pump rod joint can be used to realize the automatic discharging. With engine lathes transformed into computerized numerical control and pneumatic tailstocks coordinating revolving centers to use, partial automation production of pump rod joints can be realized.

为了切实解决企业发展中遇到的问题，可利用抽油杆接箍车削上料装置实现自动出料，通过普通车床的数控化改造和气动尾座的配合活顶尖的使用，可以实现抽油杆接箍的半自动化生产，以解决企业在生产过程中遇到的问题。
