Valve lock piece with material automatic dial type pressure head

Abstract

The invention belongs to the technical field of automobile engine manufacture, and particularly relates to a material-carrying automatic stirring-assembly-type pressure head for valve keys. The material-carrying automatic stirring-assembly-type pressure head for valve keys comprises ejection cores, stirring sleeves, permanent magnets, springs, stirring sheets, pressure head bodies and driving devices, wherein each pressure head body is of a hollow structure; the upper end of each pressure head body is connected with a substrate of a key pressing assembly machine; the lower end of each pressure head body is provided with multiple permanent magnets; the permanent magnets are used for magnetically attracting valve spring bases with the valve keys; the stirring sleeves and the ejection cores are sequentially inserted in cavities of the pressure head bodies from outside to inside; the stirring sleeves and the ejection cores can slide relatively; the springs are accommodated in the cavities of the pressure head bodies and are located above the ejection cores; the lower ends of the ejection cores are axially limited through the valve keys; one end of each stirring sheet is connected with the upper end of the corresponding stirring sleeve; and the other end of each stirring sheet is connected with the corresponding driving device arranged on the substrate. According to the material-carrying automatic stirring-assembly-type pressure head for the valve keys, manufacture if finished in one step in the pressure head by adopting ejecting and stirring; assembly time is greatly shortened; work intensity is lowered; and high efficiency of the structure on the valve key pressing assembly machine is exerted.

Description

technical field [0001] The invention belongs to the technical field of automobile engine manufacturing, in particular to an automatic dial-and-install pressure head with material for a valve lock plate. Background technique [0002] The engine is the core component of the car and the most critical factor in determining the performance of the car. The traditional process of assembling the cylinder head valve spring seat and locking plate is manual, which is labor-intensive and difficult, and the assembly quality cannot be guaranteed. In recent years, in the automobile engine manufacturing industry, the valve lock plate press machine has been widely used. The valve lock plate press machine pre-installs the spring seat and the lock plate on the valve stem, and the pressure head is designed as a push-type structure. It is completed before entering the press machine, and the preload condition meets the condition that the preload is sufficient for the valve spring compression hei...
