Description
Technical Field
The utility model relates to an engine maintenance tool specifically is special assembly and disassembly tools of gas engine cylinder cap spark plug seat.
Background
The gas generator is a main machine type for generating electricity by using low-concentration gas at home at present. The gas engine is used as a core component of the generator set and plays an important role. The cylinder cover is an important component of an engine and needs to be maintained regularly, and the problem of assembling and disassembling of the spark plug seat is always difficult in the process of maintaining the cylinder cover. The spark plug seat plays an important role in fixing the spark plug and maintaining the leakage prevention of cooling liquid in a cylinder cover, and once the spark plug seat has the phenomena of cracking, seal aging, loosening and the like, the cooling liquid leaks and the spark plug is damaged, so that the engine runs abnormally. The spark plug seat is fixed on a cylinder cover through screw threads in a standard torque of 150 N.m. The steel is in a high-temperature and high-pressure environment for a long time, and a large amount of carbon is deposited at a fastening part, so that the steel can be disassembled only by using a torsion far greater than 150 N.m. As shown in fig. 3, the spark plug base 2 is a cylindrical sleeve, threads matched with the cylinder cover 6 are arranged on the middle lower portion of the outer wall of the sleeve, a plurality of sealing grooves matched with the cylinder cover 6 are arranged in the middle of the sleeve, and cross-shaped clamping grooves which are symmetrically distributed are formed in the top end face of the sleeve. As shown in fig. 1, since the spark plug holder 2 is installed on the top end of the cylinder head 6, and four valves 7 are arranged on the periphery of the spark plug holder, interference occurs when a general wrench is used for clamping and rotating the outer edge of the spark plug holder in the assembling and disassembling process, the valves on the periphery must be disassembled first, and then the spark plug holder must be disassembled by the wrench. In addition, the sealing working surface of the side wall of the spark plug seat is extremely easy to damage in the process of using the wrench to disassemble the spark plug seat. Therefore, it is necessary to design a special dismounting tool which can conveniently and directly dismount the spark plug seat, does not interfere with the valve and does not damage the side wall sealing working surface of the spark plug seat.
Disclosure of Invention
The utility model provides a lack the special assembly and disassembly tools of gas engine cylinder cap spark plug seat at present, it is inconvenient to dismantle the spark plug seat, harms the sealed face scheduling problem of spark plug seat lateral wall easily, provides a special assembly and disassembly tools of gas engine cylinder cap spark plug seat.
The utility model discloses a realize through following technical scheme: a special disassembling tool for a spark plug seat of a cylinder cover of a gas engine comprises a guide pillar, wherein the diameter of the guide pillar is smaller than the inner diameter of the spark plug seat, a spigot chuck is fixed at the middle upper part of the guide pillar, and a buckling convex edge matched with a cross-shaped clamping groove in the top end face of the spark plug seat is arranged at the outer edge of the spigot chuck; the upper end of the guide post is fixed with a tool clamping seat, and the top surface of the tool clamping seat is provided with an inner square counter bore.
The lower end of the guide pillar is in a ball head shape; the distance from the lower surface of the spigot chuck to the lower end of the guide post is less than the distance from the upper top surface of the spark plug seat to the inner bottom of the spark plug seat.
The utility model discloses a guide pillar diameter is less than spark plug seat internal diameter, and the lower extreme becomes the noduliform, and lower extreme length is less than spark plug seat hole degree of depth, can with the vertical spark plug seat that stretches into of guide pillar in, play direction and fixed action to specialized tool, avoid rotating moreover and dismantle in-process guide pillar and rock and damage spark plug seat inner wall. The middle upper portion is fixed with the tang chuck, and the outer fringe is equipped with cross draw-in groove complex buckle bead for the tang chuck can inlay and detain in the cross draw-in groove, and further prevent that the guide pillar slope from damaging the spark plug seat inner wall. The upper end of the guide post is fixed with a tool clamping seat, the top surface of the tool clamping seat is provided with an inner square counter bore, and a column cap of a quadrangular wrench or a pneumatic tool can be inserted into the inner square counter bore to directly drive the guide post to rotate, so that the spark plug seat is driven to rotate and be dismounted.
The utility model has the advantages of it is following: 1. the structure is simple, and the manufacturing cost is low; 2. the structure is reasonable, the guiding can be realized, and the inner wall of the spark plug seat is prevented from being damaged due to deflection in the disassembly process; 3. various pneumatic tools are convenient to connect; 4. the valve body does not interfere with surrounding valves, and the disassembly process is simplified.
