Turning and milling dual-purpose machine tool special for valve rod machining

Abstract

The invention discloses a turning and milling dual-purpose machine tool special for valve rod machining. The turning and milling dual-purpose machine tool comprises a machine tool shell. A working cavity is formed in the machine tool shell. A groove turning assembly is arranged in the working cavity, and the groove turning assembly comprises a fixed support fixedly arranged on the inner wall of the rear side of the working cavity and a rotating shell rotatably connected with the fixed support and extends up and down. According to the turning and milling dual-purpose machine tool special for valve rod machining, when a workpiece needs to be subjected to a groove turning procedure, a groove can be machined in the upper surface of the rotating workpiece by releasing the rotation limiting state of a fixing clamp and moving a groove turning tool bit leftwards; and when the workpiece needs to be subjected to plane milling machining, a plane milling operation can be conducted on the upper endof the workpiece by limiting rotation of the fixing clamp and moving a rotating milling cutter rightwards. So that the groove turning procedure and a plane milling procedure of the valve rod are respectively achieved, the machining efficiency of the valve rod is improved, parts are all universal easily-replaced parts on the market, the cost is low, and unnecessary expenditure of a factory is reduced.

Description

technical field [0001] The invention relates to the field of metal processing, in particular to a special machine tool for turning and milling valve stem processing. Background technique [0002] The valve stem is an important part of the valve. It is used for transmission. The upper part is connected to the actuator or the handle, and the lower part directly drives the valve core to move or rotate to realize the valve switch or adjustment function. In general valve stem processing, it is necessary to mill the upper end of the valve stem and process the groove on the outer surface of the valve stem to ensure the subsequent assembly work. [0003] However, the valve stem processing lathes in most factories cannot perform the above two steps at the same time, resulting in the need to manually transfer the materials to the next machine tool for the next process after each process, which is not only time-consuming and laborious, but also cannot be guaranteed. The efficiency of ...

Problems solved by technology

[0003] However, the valve stem processing lathes in most factories cannot perform the above two steps at the same time, resulting in the need to manually transfer the materials to the next machine tool for the next process after each process, which is not only time-consuming and laborious, but also cannot be guaranteed. The efficiency of processing, but the cost of using machining centers and other methods is too high, and it is not suitable for low-cost manufacturing industries. A device that can solve the above problems explained by the present invention
