Abstract
The utility model discloses a shaft type mounting guide sleeve, which is characterized by comprising a guide sleeve and an unscrewing screw, wherein the unscrewing screw is arranged at the top end of the guide sleeve and the guide sleeve and the unscrewing screw are in screwed connection; a plurality of sections of stepped sectional structures are adopted in an inner hole of the guide sleeve; and each section and the inner circle of each section are matched with the diameter of an outer circle of a part to be mounted. The mounting guide sleeve of a shaft type part has the characteristics of simple structure, wide applicability, convenience in operation, high mounting efficiency and the like.
Description
Technical field
The utility model relates to the frock of machining, particularly a kind of axle class that oil sealing or keyway are arranged or the installation of revolving parts is drawn cover.
Background technology
The revolving parts of axial workpiece or coaxial line often runs into the parts such as key or oil sealing are arranged and cooperates with it in machining.Axial workpiece is the same with the part of these cooperations, its main technical requirements regulation has dimensional tolerance, geometric tolerances and mutual alignment tolerance, if cooperate bad, will affect assembly quality and the total quality of whole plant equipment, when serious even can affect the running quality of whole plant equipment.Therefore, when people are installed to this axle with these keys or oil sealing, must put into carefully or assemble, when if axial workpiece and key or oil sealing are matched in clearance, generally all install than being easier to, but when this axial workpiece and key or oil sealing are the employing interference fit, just relatively be difficult to install.At present, people beat with hand tools such as hammers (softer hammer such as wooden mallet or "painted-face" character in opera), and such way all is to control artificially dynamics by operating personnel, and when strength was too small, the installation of axle and key or oil sealing was not in place; When strength is excessive, tend to injure the matching part of part, so that axle class or revolving parts are bad with cooperating of key or oil sealing, directly affect the degree of balance of axial workpiece.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, and cover is drawn in the installation of axial workpiece simple in structure.
To achieve these goals, axle class of the present utility model is installed and is drawn cover, be characterized in: comprise and draw cover and screw out screw, screw out screw and be installed in the top of drawing cover, connect by spiral between them, the described endoporus that draws cover adopts some sections step portion segment structure mode, and each section matches with the outside diameter of want mounting parts with the inner circle of each section.
Above-described draw the cover endoporus be 1～5 section.
Compared with prior art, this axle class is installed the beneficial effect draw cover and is:
Axial workpiece of the present utility model is installed and is drawn cover, it is the size that varies in size according to the axial workpiece that will install, make the endoporus of corresponding size, when needs are installed the counterpart of the multistage counterpart of a part or a plurality of parts, the endoporus that draws cover can be made and need with it the corresponding a plurality of step size of cylindrical of installing, thereby, so that the part that is assembled reaches higher quality of fit.Originally draw cover and not only be suitable for installing axial workpiece, also be fit 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, axle class of the present utility model is installed and is drawn cover, comprise and draw cover 1 and screw out screw 2, screw out screw 2 and be installed in the top of drawing cover 1, connect by spiral between them, the described endoporus that draws cover 1 adopts two sections (ladder is arranged), and wherein one section is conical, another section is columniform structure, and inner circle matches with the outside diameter of want mounting parts.
Shown in accompanying drawing 3～4, axle class of the present utility model is installed and is drawn cover, comprise and draw cover 1 and screw out screw 2, screw out screw 2 and be installed in the top of drawing cover 1, connect by spiral between them, the described endoporus that draws cover 1 adopts two sections shoulder holes (ladder of different inner diameters) segmental structure, and wherein one section is conical, another section is columniform structure, and the inner circle of shoulder hole matches with the part outer diameter that will install.
As shown in Figure 5, in December, 2011, the cover 1 that draws of inventor design is used in oil sealing 3 is installed on YC1100 crankshaft of diesel engine 5 and main beating cap 4 parts.During installation, bent axle 5 and oil sealing 3 that needs are installed clean up, prevent that impurity from entering the position that part cooperates, at first main beating cap 4 is installed on the bent axle 5, then oil sealing 3 is inserted on the cylindrical that draws cover 1 gently, will draw cover 1 end of being inserted in bent axle 5, when placement is correct, slowly will draw the axle journal that cover 1 pushes bent axle 5, when bent axle 5 axle journals enter when drawing cover 1 inner chamber, oil sealing 3 successfully has been pressed in the axle journal of bent axle 5.Through 4 months try out, the oil sealing 3 that assembles and the cooperation of bent axle 5 have reached tolerance fully, the oil sealing 3 that is pressed into can deflection, oil sealing 3 does not have the phenomenon of damaging yet, also eliminate original oil sealing 3 often by the phenomenon of crankshaft key slot sharp edge scratch, avoided the accident of the serious quality of diesel engine leakage of oil to occur.
Embodiment 2
As shown in Figure 6, in December, 2011, the cover 1 that draws of inventor design is used in flat key 7 is installed on the axle 6.During installation, axle 6 and the flat key 7 that will need first to install clean up, prevent that impurity from entering the position that part cooperates, flat key 7 is pressed in the axle 6 gently, the end of preparing the axle 6 of installation is slowly squeezed into the inner chamber that draws cover 1, draw cover when 1 inner chamber when axle 6 enters, flat key 7 successfully has been pressed in the keyway of axle 6.Tried out 4 months, whole tool locating is correct, and the cooperation of flat key 7 and axle 6 has reached tolerance.
