Engine valve lock clamp disassembling tool and method

Abstract

The invention belongs to the field of tool clamps, and provides an engine valve lock clamp disassembling tool and method. The engine valve lock clamp disassembling tool comprises a valve-spring retainer pressing head (1), a valve lock clamp pressing head (2) and a handle (10). The valve-spring retainer pressing head (1) is a barrel body with a stepped through hole formed in the center. The valve lock clamp pressing head (2) is located in the center through hole in the valve-spring retainer pressing head (1), the upper end of the valve lock clamp pressing head (2) is sleeved with a lock clamp pressing head spring (3), the valve lock clamp pressing head (2) is of an electromagnet structure, the handle (10) is arranged at the upper end of the valve-spring retainer pressing head (1), and a power source used for controlling the electromagnet to be powered on and off is arranged and corresponds to the valve lock clamp pressing head (2). The problem that the surfaces of a valve rod and a valve lock clamp are scratched in the disassembling and assembling process of the valve lock clamp is avoided, and the service life of the valve lock clamp and the service life of an engine are prolonged.

Description

technical field [0001] The invention belongs to the field of tooling fixtures, and in particular relates to a disassembly tool and a disassembly method for an engine valve lock clip. Background technique [0002] The valve of the engine is the passage for the gas in and out of the combustion chamber. The opening and closing of the valve is realized by reciprocating movement during work, and it must bear a great deal of alternating and impact load during the movement; in the prior art, the closing of the valve is completed by the valve spring Yes, the spring transmits the pretightening force to close the valve through the valve spring seat, and the valve lock clip is the part that limits the valve spring seat to ensure the pretightening force of the valve spring for closing the valve; The valve lock clip has a two-half structure, and the outer surface of the valve lock clip is a conical surface that matches the inner wall of the valve spring seat, and the inner surface is a s...

Problems solved by technology

Since the tools used are not special tools, the operation steps are not very reasonable, so the surface of the valve stem and the valve lock clip may be scratched during the process of disassembling and installing the valve lock clip, but these scratches are not easy to detect, and There will be no faults in the short period of time the engine is working. Only after a long time of work can the faults be displayed. At this time, it is irreparable.

Therefore, the maintenance personnel's method of removing and installing the valve lock clip is unreasonable.
