Cam ejecting mechanism

Abstract

The invention discloses a cam ejecting mechanism. The mechanism comprises a propelling mechanism, an ejecting mechanism and a cam mechanism; the mechanism is composed of the propelling mechanism, theejecting mechanism and the cam mechanism. The propelling mechanism is mounted on a base of a production line through a propelling mechanism fixing plate, the propelling mechanism is used for conveyingthe ejecting mechanism to the station to be ejected, the ejecting mechanism conveys an ejector rod on an ejector rod mounting plate by a work stroke through an ejecting plate on a sliding table air cylinder, the cam mechanism is used for setting the initial position of the ejecting mechanism, and therefore it is ensured that a micro needle is precisely conveyed to the next station to be machined.The ejecting work stroke is ensured, meanwhile, the ejecting initial position is precisely determined, the precision need of length machining of a fine and long part is met, and the advantages of being simple in structure, high in use generality, and high in work reliability are achieved.

Description

technical field [0001] The invention relates to the technical field of automatic jacking and feeding in a production line, in particular to a cam jacking mechanism. Background technique [0002] At present, the realization of automatic feeding of micro parts is a major trend in the development of China's manufacturing industry. However, due to the wide variety of micro parts, such as some micro needles with special processing requirements, especially those with small size and high precision requirements for the length of the workpiece Occasionally, higher requirements are put forward for automatic ejecting materials. Most of the automatic ejecting mechanisms in the prior art can guarantee the working stroke of ejecting materials. The existing problem is that although the working stroke of ejecting materials is guaranteed, due to the inaccurate initial position, As a result, the length accuracy of the workpiece cannot be guaranteed. In order to ensure the length accuracy of ...
