Disassembling tool of engine valve collet

Abstract

The present invention discloses a disassembling tool of an engine valve collet. The disassembling tool comprises: a switch type magnet base; guide pillars, being screw rods with external threads, and each of which being vertically disposed at the top surface of the switch type magnet base respectively through one end thereof; a support plate, with a first through hole processed in one end, a threaded shaft screw hole processed in the middle portion, and a first U-shaped groove processed in another end; a handle threaded shaft, comprising a screw shaft, and a handle and a rotating ball body respectively disposed at two ends of the screw shaft; a working pressing block, with a receiving groove in a half-circular bridge hole shape in the bottom surface; and a working pressing plate, with a second through hole processed in one end, a trapezoid conical bore processed in the middle portion, and a second U shaped groove processed in another end, wherein the working pressing plate is bonded on a bottom surface of the working pressing block. The disassembling tool facilitates a serviceman to adjust an attracting position of the base on the top surface of the cylinder cover as desired, and is used for maintenance of difference valve collets.

Description

technical field [0001] The invention relates to the field of engine assembly, in particular to a dismounting tool for an engine valve lock clip. Background technique [0002] The existing tooling adopts the principle of leverage. A through hole is processed at the working end of the tooling, which can pass through the cylinder head bolt, but cannot pass through the bolt head. An oval hole is processed at a certain distance from the through hole, and the other end of the tooling is a long handle. The existing tooling needs to borrow the cylinder head bolts and the cylinder head bolt holes on the machine body, pass the borrowed cylinder head bolts through the through holes at the working end of the existing tooling, and screw them into the cylinder head bolt holes of the body (not all screwed in), the tooling The oval hole in the middle is located at the valve spring seat. Press the handle at the other end of the tooling forcefully, and the valve spring seat will move downward...

AI Technical Summary

Problems solved by technology

[0004] One, the existing tooling is large in size and heavy in weight. When disassembling the valve lock clips of multiple valves, the cylinder head bolts need to be screwed in and out of different cylinder head bolt holes on the body. The workload of the maintenance personnel is relatively large. Maintenance personnel need to cooperate, and work efficiency is low;

[0005] Second, once the through hole at one end of the existing tooling is processed, it can only be applied to the removal of the valve lock clip of a specific type of engine, and cannot be used universally

[0006] Its three, existing tooling needs to borrow the cylinder head bolt hole on the body, the cylinder head bolt, the cylinder head bolt hole on the body and the cylinder head bolt thread easily cause sliding teeth to be scrapped; If the teeth are slippery, it will affect the tightening torque of the cylinder head bolts. If the torque of the cylinder head bolts is insufficient, the fatal failure of the cylinder head gasket will occur during the working process of the engine, resulting in the scrapping of the entire engine.
