Automatic screening machine device for valve ejector rods

Abstract

The invention discloses an automatic screening machine device for valve ejector rods, and relates to the technical field of valve mandrels. The automatic screening machine device comprises a bottom waste box, vertical supporting plates are fixedly connected to the two sides of the top of the bottom waste box, connecting stabilizing blocks are fixedly connected to one sides of the surfaces of the vertical supporting plates, an ejector rod body is fixedly connected to the left sides of the connecting stabilizing blocks, an ejector pin is arranged on one side of the ejector rod body, one end of the ejector pin is fixedly connected with an ejector cap, and the surface of the ejector rod body is sleeved with a fixed reinforcing arc-shaped box. According to the automatic screening machine devicefor the valve ejector rods, when the device returns at a high speed, a connector at the bottom of the ejector cap can make movable contact with a contact plate, the impact force generated when the ejector cap returns is stably released by a buffer spring in the fixed reinforcing arc-shaped box, ejector rod deformation caused by large impact force when the ejector cap returns is effectively avoided, the safety of the whole structure of the device is improved, the structure is simple, and secondary maintenance of workers is facilitated.

Description

technical field [0001] The invention relates to the technical field of valve ejector rods, in particular to an automatic screening machine device for valve ejector rods. Background technique [0002] Machinery is a tool device that can help people reduce the difficulty of work or save labor. Items such as chopsticks, brooms, and tweezers can all be called machines, and they are simple machines. A complex machine is composed of two or more simple machines. These more complex machines are usually called machines. From the point of view of structure and motion, there is no difference between mechanism and machine, which is generally called machinery. The development of various engineering fields requires the development of mechanical engineering to adapt to it, and requires mechanical engineering to provide the necessary machinery. The invention and improvement of certain machinery will lead to the emergence and development of new engineering technologies and new industries. ...
