Description
Technical field
This utility model relates to miniature diesel engine piston ring mounting technique, is related specifically to a kind of miniature diesel engine piston ring erecting device.
Background technology
Miniature diesel engine piston needs several piston rings are installed, on the end outer wall of piston, several annular groove it is provided with for this, the width of its groove and the degree of depth and piston ring to be mounted match, say, that the thickness of the piston ring being arranged on piston and diameter are different.Generally, piston ring adopts the elastomeric material of spring steel one class to make, and its end surface shape is U-shaped horizontal, outward opening, is provided with breach, in order to be arranged on piston by piston ring on ring.Prior art miniature diesel engine piston ring installation method adopts after manually being broken into two with one's hands by piston ring, is sleeved on piston, then shifts suitable position onto.Owing to piston ring is through Quenching Treatment, fragility is relatively big, is easy to fracture when breaking into two with one's hands.Obviously, prior art type diesel motor piston ring installation method also exists inefficiency, wastes time and energy, labor intensity breaks more greatly and easily the problems such as disconnected piston ring.
Summary of the invention
For solving inefficiency that prior art type diesel motor piston ring installation method exists, waste time and energy, labor intensity breaks the problems such as disconnected piston ring more greatly and easily, the utility model proposes a kind of miniature diesel engine piston ring erecting device.This utility model miniature diesel engine piston ring erecting device, including pedestal, lead, control bar and promotion ring；Described pedestal is rectangular shape, is provided with the lead identical with the piston ring quantity of required installation thereon；Described lead upper surface is provided with circular groove, the diameter of described circular groove is identical with piston external diameter, the wall thickness of described circular groove is less than 1mm, the degree of depth of described circular groove is identical to the distance of end face be arranged on piston respectively with each piston ring after, namely identical to the distance of end face with each annular groove on pistons end outer wall respectively；Described control bar is arranged on the center of circular groove and is connected with controlling organization, and the distance of its upper surface and circular groove bottom surface is less than 1mm；Described promotion ring set is contained in outside lead, and its internal diameter and lead external diameter match, and its external diameter is big compared with piston ring external diameter, is connected with pushing mechanism bottom it.
Further, described pushing mechanism is for driving cylinder.
The Advantageous Effects of this utility model miniature diesel engine piston ring erecting device is to adopt mechanical erection piston ring, effectively reduces the labor intensity that piston ring is installed, improves installation effectiveness, it is ensured that installation quality.
Accompanying drawing explanation
Accompanying drawing 1 is miniature diesel engine piston ring scheme of installation；
Accompanying drawing 2 is the schematic three dimensional views of this utility model miniature diesel engine piston ring erecting device；
Accompanying drawing 3 is the schematic diagram of this utility model miniature diesel engine piston ring erecting device ring installation.
Below in conjunction with the drawings and specific embodiments, this utility model miniature diesel engine piston ring erecting device is further described.
Detailed description of the invention
Accompanying drawing 1 is miniature diesel engine piston ring scheme of installation, and in figure, A is piston, and B is piston ring.As seen from the figure, miniature diesel engine piston needs several piston rings are installed, on the end outer wall of piston, several annular groove it is provided with for this, the width of its groove and the degree of depth and piston ring to be mounted match, say, that the thickness of the piston ring being arranged on piston and diameter are different.Generally, piston ring adopts the elastomeric material of spring steel one class to make, and its end surface shape is U-shaped horizontal, outward opening, is provided with breach, in order to be arranged on piston by piston ring on ring.Prior art miniature diesel engine piston ring installation method adopts after manually being broken into two with one's hands by piston ring, is sleeved on piston, then shifts suitable position onto.Owing to piston ring is through Quenching Treatment, fragility is relatively big, is easy to fracture when breaking into two with one's hands.Obviously, prior art type diesel motor piston ring installation method also exists inefficiency, wastes time and energy, labor intensity breaks more greatly and easily the problems such as disconnected piston ring.
Accompanying drawing 2 is the schematic three dimensional views of this utility model miniature diesel engine piston ring erecting device, and accompanying drawing 3 is the schematic diagram of this utility model miniature diesel engine piston ring erecting device ring installation, in figure, 1 is pedestal, 2 is lead, and 3 for controlling bar, and 4 for promoting ring.This utility model miniature diesel engine piston ring erecting device, including pedestal 1, lead 2, controls bar 3 and promotes ring 4；Described pedestal 1 is rectangular shape, is provided with the lead 2 identical with the piston ring quantity of required installation thereon；Described lead 2 upper surface is provided with circular groove, the diameter of described circular groove is identical with piston external diameter, the wall thickness of described circular groove is less than 1mm, the degree of depth of described circular groove is identical to the distance of end face be arranged on piston respectively with each piston ring after, namely identical to the distance of end face with each annular groove on pistons end outer wall respectively；Described control bar 3 is arranged on the center of circular groove and is connected with controlling organization, and the distance of its upper surface and circular groove bottom surface is less than 1mm；Described promotion ring 4 is sleeved on outside lead 2, and its internal diameter and lead 2 external diameter match, and its external diameter is big compared with piston ring external diameter, is connected with pushing mechanism bottom it.As shown in Figure 3, time specifically used, first piston ring is sleeved on the lead of correspondence by the position being each arranged on piston, and set installs to the endface position of lead always；Then, being inserted downwards by the piston end surface of piston ring to be installed in the circular groove of lead, owing to the diameter of circular groove is identical with piston external diameter, what piston can consolidate inserts.When piston end surface touches control bar, controlling bar and send signal to controlling organization, controlling organization controls pushing mechanism and promotes ring to move up the distance of a piston ring thickness, is in the piston ring of lead end face and departs from lead and slide to piston；Due on lead the degree of depth of circular groove be arranged on piston with each piston ring after identical to the distance of end face, that is, now piston just there is the annular groove of to be in the endface position of lead, slide to the piston ring of piston just in annular groove on outside piston, thus, the installation of a piston ring is completed.By that analogy, different leads just can complete the installation of the piston ring of different size.Obviously, comparatively conventional pushing mechanism is preferably and drives cylinder.
Obviously, the Advantageous Effects of the small-sized diesel motor piston ring erecting device of this utility model this utility model is to adopt mechanical erection piston ring, effectively reduces the labor intensity that piston ring is installed, improves installation effectiveness, it is ensured that installation quality.
