Abstract
The invention discloses a tool special for disassembling a cylinder cover seat ring of an engine which is specially used for disassembling the cylinder cover seat ring of the engine and a disassembling method. The tool consists of a hammer, a remanufactured valve and pliers, wherein one end of the remanufactured valve is a round face cone-shaped body while the other end is a stress rod end; and the end faces of the pliers are planes. The tool and the method have the advantages that: first, waste products caused by a process for machining a hole of a seat ring of the engine are reduced greatly and the production cost is saved; and second, the tool and the process for taking the seat ring are novel, unique and simple; and one piece of the tools can be taken out in about 7 minutes.
Description
Technical field
The present invention relates to a kind of engine cylinder cover seat ring dismounting special tooling and method for dismounting that is specifically designed to dismounting engine cylinder cover seat ring, belong to engine cylinder cover seat ring dismounting special tooling and make the field.
Background technology
Engine cylinder cover seat ring hole is in process, because product required precision height, so that in process, produce waste product.Under the normal condition, the our factory adds nearly 120/day of the cylinder cover that producer so problem scrap.Because cylinder cover blank price is wanted 300 yuan/part, consider the production cost problem, so need the seat ring of the type cylinder cover is taken out, the wedge circle is done over again again again.But, objective reality be: because this seat ring is use cooled with liquid nitrogen when being pressed into cylinder cap, the design magnitude of interference is at 0.10-0.15mm, and the seat ring material is that V5(can't weld), therefore cause seat ring to be difficult to taking-up, careless slightly, will make and cause whole cylinder cover to be scrapped.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design a kind of engine cylinder cover seat ring dismounting special tooling and method for dismounting that is specifically designed to dismounting engine cylinder cover seat ring.
Design: in order to realize above-mentioned purpose of design.1, transformation of the way valve one end is that disc bullet, the other end are the design of stressed rod end, is one of technical characterictic of the present invention.The purpose of doing like this is: the one, and minute body structure both can make the disc bullet be tucked on the seat ring by the engine cylinder cover sidepiece, and force rod can directly be pegged graft by passage and disc bullet, thus reach the dismounting purpose of counter race.2, the pliers end face is the design on plane, is two of technical characterictic of the present invention.The purpose of doing like this is: this pliers end face can form good coincideing with the seat ring face, and the suffered power of seat ring is delivered to around the seat ring by the pliers end face, makes and makes seat ring loosening and be removed in percussion vibration.
Technical scheme 1: engine cylinder cover seat ring dismounting special tooling, it is characterized in that constituting by hammer, transformation of the way valve and pliers, described transformation of the way valve one end is that disc bullet, the other end are stressed rod end; Described pliers end face is the plane.
Technical scheme 2: the method for dismounting of engine cylinder cover seat ring dismounting special tooling, ⑴ withstands engine cylinder cover seat ring outside with the end face of pliers and pliers end face institute opening angle can make the pliers end face touch mutually with engine cylinder cover seat ring edge just; ⑵ the disc bullet that will change a social system valve is mid-from cylinder sidepiece hole goes in the seat ring and the disc the disc bullet is touched mutually with the engine cylinder cover seat ring, duct and disc bullet in the cylinder of again force rod being bored a hole; ⑶ while knocking force rod, use the pliers end face to press closer engine cylinder cover seat ring outside, but the hammer percussion power can take off the engine cylinder cover seat ring greater than the top power of pliers with hammer.
The present invention compares with background technology, and the one, greatly reduced the product waste product that is caused because of in the process of engine seat ring hole, saved production cost, raise labour productivity; The 2nd, get seat ring frock, technology novelty, uniqueness, simple, can take out one about 7 minutes.
Description of drawings
Fig. 1 is engine cylinder cover seat ring dismounting special tooling and the structural representation of dismantling the seat ring method.
The specific embodiment
Embodiment 1: with reference to accompanying drawing 1.Engine cylinder cover seat ring dismounting special tooling, constitute by hammer 3, transformation of the way valve 2 and pliers 1, described transformation of the way valve 2 one ends are that disc bullet, the other end are stressed rod end, and disc bullet in the described transformation of the way valve 2 and stressed rod end are the split connected structure; Described pliers 1 end face is the plane.
The disc of the disc bullet of described transformation of the way valve 2 and engine cylinder cover seat ring hole internal diameter match and are matched in clearance.
Embodiment 2: on the basis of embodiment 1, the method for dismounting of engine cylinder cover seat ring dismounting special tooling, ⑴ withstands engine cylinder cover seat ring 4 outsides with the end face of pliers 1 and pliers end face institute opening angle can make pliers 1 end face touch mutually with engine cylinder cover seat ring 4 edges just; ⑵ the disc bullet that will change a social system valve 2 is mid-from cylinder sidepiece hole goes in the seat ring and the disc the disc bullet is touched mutually with the engine cylinder cover seat ring, duct and disc bullet in the cylinder of again force rod being bored a hole; ⑶ while knocking force rod, use pliers 1 end face to press closer engine cylinder cover seat ring outside, but hammer 3 percussion powers can take off the engine cylinder cover seat ring greater than the top power of pliers 1 with hammer.
What need understand is: though the foregoing description is to the mentality of designing of the present invention detailed text description of contrasting; but these text descriptions; just the simple text of mentality of designing of the present invention is described; rather than to the restriction of mentality of designing of the present invention; any combination, increase or modification that does not exceed mentality of designing of the present invention all falls within the scope of protection of the present invention.
Claims (4)
1. an engine cylinder cover seat ring dismounting special tooling is characterized in that being made of hammer, transformation of the way valve and pliers, and described transformation of the way valve one end is that disc bullet, the other end are stressed rod end; Described pliers end face is the plane.
2. engine cylinder cover seat ring dismounting special tooling according to claim 1, it is characterized in that: the disc of the disc bullet of described transformation of the way valve and engine cylinder cover seat ring hole internal diameter match and are matched in clearance.
3. engine cylinder cover seat ring dismounting special tooling according to claim 1, it is characterized in that: disc bullet in the described transformation of the way valve and stressed rod end are the split connected structure.
