Abstract
The utility model discloses a piston ring installation guide sleeve. The piston ring installation guide sleeve comprises an outer ring and an inner ring. The piston ring installation guide sleeve is characterized in that the inner ring is in a cylinder shape, a cone shape or a step shape, and the size of the inner ring matches with the outer circle diameter of a part to be installed. The piston ring installation guide sleeve has the advantages of being simple in structure, wide in adaptability, convenient to operate, high in installation efficiency and the like.
Description
Technical field
The utility model relates to the frock in the machining, particularly a kind of piston ring mounting guide sleeve.
Background technology
The diesel engine piston connection rod set is the driving member of engine, and the piston rod group mainly is comprised of piston, piston ring, piston pin and connecting rod etc.The effect of piston rod group is the gyration that the linear reciprocating motion of piston is transformed into bent axle, so that outside output work that is to say the pressure of burning gases is passed to bent axle, makes crankshaft rotating and outputting power.The effect of connecting rod is that the power that piston bears is passed to bent axle, and cooperates with bent axle piston linear reciprocating motion is become rotatablely moving of bent axle.Have groove on the piston, piston ring just is installed in the annular groove of piston.In general, the piston of diesel engine has three road rings.The twice compression ring, one oil ring.Each piston ring needs to install respectively in each annular groove that embeds piston, again piston rod is assembled in the cylinder jacket, if cooperate badly, will affect assembly quality and the total quality of piston rod group, when serious even can affect the running quality of whole diesel engine.Therefore, the installation quality of piston ring is one of important link to the installation quality of complete machine.At present, people beat with hand tools such as wooden stick or hammers, and such way all is to control artificially dynamics by operating personnel, and when strength was too small, piston ring can't enter in the cylinder jacket; When strength is excessive, tend to injure or break part, directly affect the installation quality of piston rod group.Therefore, above defective becomes the technical barrier of the industry.
Summary of the invention
The purpose of this utility model namely is to provide a kind of and can overcomes the deficiency that prior art exists, piston ring mounting guide sleeve simple in structure.
To achieve these goals, piston ring mounting guide sleeve of the present utility model comprises outer ring and inner ring, is characterized in: described inner ring is cylindrical, taper shape or stairstepping, and the size of inner ring matches with the outside diameter of want mounting parts.
Compared with prior art, the beneficial effect of this piston ring mounting guide sleeve is:
Piston ring mounting guide sleeve of the present utility model is the part according to the different size dimensions that will install, make the cylindrical or conical endoporus of corresponding size, thereby, so that the part that is assembled reaches higher quality of fit, the utility model not only is suitable for the installation of various model piston rings, also can be extended to the installation to the revolving parts of coaxial line, have simple in structure, wide adaptability, easy to operate, the installation effectiveness advantages of higher.

The specific embodiment
Below in conjunction with drawings and Examples structure of the present utility model is described.
Shown in accompanying drawing 1～2, piston ring mounting guide sleeve of the present utility model comprises outer ring 1-1 and inner ring 1-2, and described inner ring 1-2 is cylindrical, taper shape or stairstepping, and the size of inner ring 1-2 matches with the outside diameter of want mounting parts.
As shown in Figure 3, in December, 2011, the inner ring 1-2 of inventor's design is conical guide pin bushing 1, is used in the piston rod group is installed in the cylinder jacket of diesel engine 5.During installation, connecting rod 2, piston ring 3 and the piston 4 that needs are installed the especially annular groove of piston 4 cleans up, prevent that impurity from entering the position that part cooperates, at first piston 4 is installed to the end of connecting rod 2, then piston ring 3 is inserted in gently in the corresponding groove of piston 4 cylindricals, the opening direction of rotary-piston ring 3 is to assigned address, the inner ring 1-2 of conical guide pin bushing 1 being aimed at the end of piston 4 slowly puts into, piston ring 3 slowly dwindles along the inner ring 1-2 of guide pin bushing 1, until the piston rod group all enters in the cylinder jacket 5.Through this guide pin bushing 1 was tried out 4 months, the phenomenon damaging, squeeze off did not all occur in piston 4 and piston ring 3, had guaranteed the installation quality of diesel engine piston connection rod set.
