Abstract

The utility model discloses a rim extension mould which mainly comprises a template, a cone, a module and a mould seat, wherein the mould is an annular mould formed by connecting a plurality of sector-subsection moulds, the top of the cone is fixedly connected with the template, the bottom of the cone is fixedly connected with a subplate, the cone is matched with the conical hole at the center of the mould, and the mould is arranged above the mould seat, the upper surface of the mould is provided with a circular guide plate, and a T-shaped guide groove is arranged a position of the guide plate corresponding to each sector subsection mould, and internally provided with a T-shaped guide key matched with the T-shaped groove, the T-shaped guide key is connected with the sector subsection mould and slides in the T-shaped guide groove to drive the mould to contract and extend; the mould guide part of the existing rim extension mould is changed to be the T-shaped keys and grooves for guiding from an inner hexagon screw, the T-shaped guide keys move back and forth by the limitation of the scope of the T-shaped guide grooves, the force bearing strength is greatly more than that of the original inner hexagon screw, so that the guide strength is enhanced.

Description

The wheel rim extension module
Technical field
The utility model relates to motor vehicle, tool car art of wheels, a kind of more precisely wheel rim extension module.
Background technology
The most approaching with the application also is that the best prior art of present result of use is patent (the wheel rim extension module of also having been authorized by the applicant's application in 2010; The patent No. is " 201020555469.9 "); The primary structure of this patent is, template and cone connect as one through hexagon socket head cap screw, and template and cone are simultaneously descending during work; Push module under the cone ramp effect (being made up of ten split fritters) is opened, and couples together with upper and lower two groups of springs between ten split little modules.Module passes through to connect soket head cap screw along the spacing outside slip of the gathering sill on the guide plate, thereby diameter of work is enlarged.This wheel rim extension module in use because module is stressed stable inadequately, and the stressed insufficient strength of soket head cap screw can not smooth and easyly be slided in the gathering sill on guide plate, causes the soket head cap screw fracture easily.
The utility model content
The purpose of the utility model is to provide a kind of guiding mechanism wheel rim extension module smoothly that slides.
The purpose of the utility model is achieved through following technical scheme: the wheel rim extension module, mainly comprise template, cone, module and die holder, and said module is the circular module that is connected to form through spring by some fan-shaped split modules; The circle ring center hole of module is a bellmouth wide at the top and narrow at the bottom; Said cone top is fixedly connected with template, and cone base is fixedly connected with supporting plate, and cone cooperates with the bellmouth of module centers; Module places the top of die holder; The upper surface of said module is provided with an annular guide plate, it is characterized in that: the position of the corresponding every fan-shaped split module of guide plate is equipped with T type gathering sill, is provided with the T type feather key that cooperates with it in the T type gathering sill; T type feather key is fixedly connected with fan-shaped split module, and T type feather key slip band dynamic model piece in T type gathering sill shrinks and expansion.
The trend of said T type gathering sill is to point to cylindrical along circle in the guide plate.
Be fixedly connected through screw between said T type feather key and the fan-shaped split module.
Said module is the circular module that is connected to form through spring by 11 fan-shaped split modules.
Transform the module targeting part of existing wheel rim extension module as T type keyway guiding by soket head cap screw; The scope restriction that T type feather key receives T type gathering sill moves around; The force intensity that receives of T type feather key is far longer than the force intensity that receives of original soket head cap screw, has increased guiding intensity.Avoided in the use of existing wheel rim extension module because the stressed instability of module, the situation that soket head cap screw can not smooth and easy slip in gathering sill causes rupturing takes place.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the cross sectional representation of T type gathering sill;
Fig. 3 is the cross sectional representation of T type feather key.
The specific embodiment
As shown in Figure 1, the wheel rim extension module mainly comprises template 2, cone 3, module 7 and die holder 9; Module 7 is the circular modules that connected to form through spring 8 by 11 fan-shaped split modules, and the circle ring center hole of module is a bellmouth wide at the top and narrow at the bottom, and cone 3 tops adopt soket head cap screw 1 to be fixedly connected with template 2; Cone 3 bottoms adopt soket head cap screw 10 to be fixedly connected with supporting plate 11; Cone 3 cooperates with the bellmouth of module centers, and module 7 places the top of die holder 9, and the upper surface of module 7 is provided with an annular guide plate 6; The position of guide plate 6 corresponding every fan-shaped split modules is equipped with T type gathering sill 6a (see figure 2); The trend of T type gathering sill 6a is to point to cylindrical along circle in the guide plate, is provided with T type feather key 5 (see figure 3)s that cooperate with it in the T type gathering sill 6a, and employing soket head cap screw 4 is fixedly connected between T type feather key 5 and the fan-shaped split module; T type feather key 5 slip band dynamic model piece 7 in T type gathering sill 6a expands outwardly, and module 7 drives workpiece 12 and expands outwardly.
The foregoing description only is the preferred embodiments of the utility model; The technical conceive and the essential implementation of the utility model have been specified; Be not to be that protection domain to the utility model limits; All any simple modification and equivalent structure transformation or modifications of being done according to the utility model spirit all should be encompassed within the protection domain of the utility model.

Claims (4)
