The invention discloses a cylinder cover valve spring cover and a keeper pressing assembly device, which are characterized in that the invention comprises a pressing head external bushing which is provided with an ejector pin and a pressure head core body; the ejector pin is sheathed with an internal spring and an external spring and a spring pressure cover is sheathed on the ejector pin; a compression plug screw on the ejector pin is connected with the pressing head external bushing by screw thread; a core body sheath is arranged outside the pressure head core body, and the valve spring cover, a valve split collet, a valve spring, a valve ejector pin and related parts for a valve spring retainer are arranged below the core body sheath in sequence. The process of pressing and assembly comprises 6 actions; wherein, the pressing head external bushing is driven to be contacted with the valve spring by Action I; the pressure head core body is driven to be contacted with the ejector pin by Action II; the core body sheath is driven to be contacted with the valve split collet and the side of the pressure head core body is caused to slide into the end part of the valve ejector pin by Action III; the valve split collet is pressed into a space below the end part of the valve ejector pin by Action IV; the valve split collet is pressed into a space below a ring-shaped groove at the end part of the valve ejector pin by Action V; a pressure head is lifted, the valve spring is reset and the valve split collet is clamped into the ring-shaped groove of the valve ejector pin by Action VI.
Description
technical field [0001] The invention relates to a cylinder head valve spring cover and a locking plate pressing device, which is used for pressing the cylinder head valve spring cover and the locking plate in mass production and manufacturing of engines. Background technique [0002] At present, in the production and manufacture of engines, many manufacturers still use simple hollow press-fitting heads for the press-fitting of cylinder head valve spring covers and locking plates. The efficiency of this method of assembly is low, and the assembly quality is greatly affected by the accuracy of the workpiece itself. Therefore, in mass production, the contradictions of low efficiency and unstable assembly quality are more prominent, and a new press-fitting head is needed to improve production quality. Contents of the invention [0003] In order to overcome the shortcomings of the existing press-fitting methods, the invention provides a cylinder head valve spring cover and a l...
