A valve spring upper washer and lock clip removal tool

Abstract

The invention relates to the technical field of engine dismounting aids and discloses a dismounting tool for an upper spring gasket and a locking clamp of an air valve. The dismounting tool comprises a first supporting long shaft and a second supporting long shaft; the two ends of the first supporting long shaft are connected with a first supporting column and a second supporting column, respectively; the two ends of the second supporting long shaft are connected with a third supporting column and a fourth supporting column, respectively; a connecting arm is arranged between the first supporting long shaft and the second supporting long shaft; a dismounting assembly is connected to the connecting arm, and comprises a fixing block with an internal-thread hole, a screw matched with the internal-thread hole and a dismounting sleeve fixed at an end of the screw and provided with a side opening. The dismounting tool is convenient to use without causing damage to the parts of the air valve, and is capable of preventing the parts from splashing; as a result, the safety is improved.

Description

technical field [0001] The invention relates to the technical field of engine disassembly and assembly aids, in particular to a valve spring upper gasket and lock clip disassembly tool. Background technique [0002] The traditional method of installing gaskets and lock clips on engine valve springs usually uses the most primitive manual assembly method. During assembly, usually two people cooperate, one person presses down the valve spring with a hollow mandrel slotted on one side, and the other quickly installs the gasket and lock clip on the valve spring in place, loosens the mandrel, and restores the spring. Compress the spring top washer and lock clip. When disassembling, due to the lack of special tools, the method of violent disassembly is usually used, that is, one end of the mandrel is used to press the gasket on the spring, and then the other end of the mandrel is hit with a rubber hammer. Under the great impact force, the lock clip falls off. The gasket on the va...

Problems solved by technology

[0003] According to the traditional method of installing the gasket and lock clip on the valve spring, due to the valve inclination angle of some engine blocks and the rough assembly tools, the assembly efficiency is low, and the assembly is laborious, which seriously affects the assembly efficiency; the traditional method is used to disassemble the valve spring upper Gaskets and lock clips are very likely to cause structural damage to the valve springs and gaskets on the valve springs, and more seriously, may damage the valve sealing structure of the engine block, resulting in the scrapping of the engine block

If the gasket and lock clip on the valve spring are removed from the whole machine in the traditional way, under the action of the impact force, the lock clip will fall off and splash, and it is likely to fall into the oil pan. When starting the car, since the lock clip is still in the oil pan, it is very likely that random oil will enter the lubrication system or block the engine filter, causing serious consequences
