Detailed Description
In order to illustrate the invention more clearly, the invention is further described below with reference to preferred embodiments. It is to be understood by persons skilled in the art that the following detailed description is illustrative and not restrictive, and is not to be taken as limiting the scope of the invention.
In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "front", "rear", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
In the description of the present invention, it should be noted that unless otherwise explicitly stated or limited, the terms "mounted," "connected" and "disposed" are to be construed broadly, and may for example be fixedly connected, disposed, detachably connected, disposed, or integrally connected and disposed. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1 to 6, a spherical shell assembling jig includes: the spherical shell comprises a bottom plate 1, wherein an accommodating cavity 2 is formed in the bottom plate 1, and the lower half part of a spherical shell is placed in the accommodating cavity 2; the bottom plate does not require a shape, and can be adjusted adaptively according to different machine tools, such as a round shape, a trapezoid shape and the like.
Obviously, the containing cavity can also be directly fixed on the machine tool.
A cavity 201 is arranged below the inside of the accommodating cavity 2, and the connecting edge of the cavity 201 and the accommodating cavity 2 is in smooth transition; the design of cavity has reduced the required precision to the tool, if hold intracavity portion be the hemisphere type, then to the dimensional requirement comparatively strict, prevent that globular shell from producing deformation, the precision improves greatly to increase manufacturing cost. When the bottom is provided with the cavity, the precision requirement of the accommodating cavity is only equivalent to a section of cambered surface contacting the side surface of the spherical shell, and the depth of the accommodating cavity is equal to the radius of the spherical shell.
In particular, the junction between the cavity and the receiving cavity must be designed with a smooth transition to prevent pressure from impressing the spherical shell surface.
The top that holds chamber 2 is equipped with tool 3, the bottom of going up tool 3 is equipped with and is used for placing first half spherical shell on hold chamber 301, just it is less than first half spherical shell height to hold the chamber 301 degree of depth on.
It will be appreciated that when the depth of the upper receiving chamber is less than the height of the upper half of the spherical shell, the spherical shell will be partially exposed so that during assembly, the stress on the exposed portion is maximized, thereby avoiding stress deformation in the thinner portion of the top of the spherical shell, i.e. the design described above will be able to divert the stress-producing portion.
It is worth mentioning that the thickness of the joint of the spherical shell is the largest, since there are three plug pins inside.
The top of the upper jig 3 is provided with a solid pressure part 302; the pressure part 302 and the upper accommodating cavity 301 are connected through a contraction part 303, and the diameter of the contraction part 303 is smaller than that of the pressure part 302 and the upper accommodating cavity 301; the junction of the contraction part, the pressure part and the upper containing cavity is in smooth transition.
The contraction part is used for clamping the upper jig by external equipment to move.
The jig capable of wrapping more than 95% of the spherical shell area is designed, so that the quality problems of cracking, deformation, spherical surface depression and the like of the spherical shell due to stress during assembly of the spherical shell are avoided; through the solid pressure portion of design, during the assembly at every turn, assemble spherical shell through the gravity of self to the same technical purpose of the overdraft of assembly at every turn has been reached.
Further, the side surface of the pressure part 302 is provided with a plurality of positioning holes 4, and the positioning holes 4 comprise a column body area 401 and a cone body area 402. This application has adopted four locating holes to interval 90 each other, the locating hole is used for outside locating lever disect insertion locating hole in, drives whole tool of going up and rotates, makes the first one of globular casing and the grafting round pin of lower half aim at.
Further, a fixing hole 5 is formed in the center of the upper surface of the pressure portion 302. The fixed holes are used for ensuring that the upper jig moves up and down on the same straight line. Usually, a telescopic cylinder is inserted into the fixing hole.
Furthermore, four threaded holes 6 are formed in the bottom plate 1. The accommodating cavity is fixed on the bottom plate through bolts.
Further, the accommodating part is a cylinder made of Q235 steel. The pressure part is a cylinder made of Q235 steel. Under the same circumference, the circular area is the largest, and meanwhile, the cylindrical shape is convenient to rotate and is butted with the spherical shell inserting pin. Therefore, the whole jig is designed to be cylindrical.
The working principle of the device is as follows:
through the shrink portion of tool in the outside apparatus centre gripping, will go up the tool and promote, hold the chamber and hold the intracavity on and place two half globular shells respectively, through the rotatory tool that goes up of outside power, guarantee that the grafting round pin of two half globular shells is aimed at, then utilize gravity to make and go up the tool whereabouts, succeed in assembling two globular shells.
It should be noted that the upper jig, although depending on gravity, does not mean a direct free fall, and its movement stroke is still limited by the external instrument gripping the constriction. Prevent the spherical shell from being damaged by excessive pressing.
Obviously, the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention, and it is obvious for those skilled in the art to make other variations or changes based on the above descriptions, and all the embodiments cannot be exhausted here, and all the obvious variations or changes that belong to the technical solutions of the present invention are still in the protection scope of the present invention.
