The outer side of the cross section of the octagonal section is regularly octagonal, so that the stability of the octagonal section is greatly improved; and through holes are formed in eight faces of the octagonal section, so that the octagonal section is convenient to connect through a connecting piece, position accurately and adjust relatively.

Description

Eight prismatic section bars

Technical field

The utility model relates to mechanical field, relates in particular to a kind of eight prismatic section bars.

Background technique

At present; The used section bar of car body welding producing line grasping device skeleton is a pipe; So simple and have higher-strength and be used widely because of circular tube structure, but also there is following deficiency in pipe: and 1, the location pilot hole on the pipe is to process according to different designing requirements, so versatility is poor; Can not realize commercialization, seriation, the generalization of section bar, product development cycle is prolonged.2, the relative fixed of circumferencial direction is the frictional force between leaning on two between pipe and pipe link; Bear than big active force or with when movement velocity is moved greatly at pipe; Can produce the trace change between pipe and pipe link, so the connective stability between pipe and the pipe is relatively poor.3, if when deviation appears in the design of pipe and actual conditions, must interconnect also between the pipe and can't accomplish accurate adjustment.

Therefore, existing technology awaits to improve and development.

The model utility content

In view of the deficiency of above-mentioned existing technology, the purpose of the utility model is to provide a kind of eight prismatic section bars, problem such as be intended to solve existing tubing poor stability, versatility difference and can't accurately adjust.

The technological scheme of the utility model is following:

A kind of eight prismatic section bars, wherein, the cross section of the said eight prismatic section bars outside is an octagon.

Described eight prismatic section bars, wherein, the cross section of said eight prismatic section bars inboard is circular.

Described eight prismatic section bars, wherein, eight faceted pebbles of said eight prismatic section bars are provided with several equidistance location and installation holes.

Described eight prismatic section bars, wherein, the through hole of said eight prismatic section bars is arranged on the centre of faceted pebble.

Described eight prismatic section bars, wherein, the inside of said eight prismatic section bars is provided with stiffening rib.

Described eight prismatic section bars, wherein, said eight prismatic section bars are aluminium matter or aluminum alloy matter eight prismatic section bars.

Embodiment

The utility model provides a kind of eight prismatic section bars, for purpose, technological scheme and the effect that makes the utility model is clearer, clear and definite, below to the utility model further explain.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

See also Fig. 1, Fig. 1 is first embodiment's of the utility model eight prismatic section bars the first visual angle structural representation, and the cross section outside 110 of said eight prismatic section bars is an octagon; As shown in Figure 2, the certain polygonal that also can be arranged to other is like dodecagon or icosagon; This polygonal section bar, its stressed balance more, good stability; Preferred embodiment is that its cross section outside 110 is set to octagon; Thereby it has a plurality of surface of contact that can be connected with eight prismatic section bar links, thereby is convenient to the connection of section bar, and strengthens connection stability.

The cross section of said eight prismatic section bars inboard 120 be a circle, and the round structure of hollow can alleviate the weight of section bar; Resistance to bending that can also reinforcing profile, in addition, hollow circular can also insert some pipe fittings that need insert; To enlarge the application area of the utility model eight prismatic section bars, the structure of hollow circular also is easy to moulding, and the inboard, cross section of the utility model eight prismatic section bars is not limited to be circle certainly; Also can be set to other shape; For example be set to like the similar Octagon in the outside, perhaps other polygonal is so that eight prismatic section bars satisfy some other special arts demands.In addition, said eight prismatic profile materials are generally aluminum or aluminum alloy, and this material proportion is little, and moulding is easy, and have intensity and toughness preferably.

The embodiment of the utility model eight prismatic section bars, as shown in Figures 2 and 3, eight faceted pebbles of said eight prismatic section bars are provided with several through holes 140.Said through hole 140 is evenly distributed on eight faceted pebbles, and the center line of through hole 140 and eight prismatic shaft axiss intersect vertically, and the spacing of through hole 140 is equivalent, and the effect of this through hole 140 is to realize accurately being located by connecting with other part of grasping device, and can realize accurately adjustment.Concrete adjustment is the installing and locating hole of selecting according to actual needs on the section bar, adjusts the relative position of eight prismatic section bar links and eight prismatic section bars, so that a plurality of eight prismatic section bars, section bar link are connected with the change of designing requirement.

As shown in Figure 1, the inside of said eight prismatic section bars also is provided with stiffening rib 150, and this stiffening rib 150 can improve the strength and stiffness of eight prismatic section bars, and the also unlikely simultaneously eight prismatic section bar weight that make are excessive.And, can effectively improve the non-deformability of eight prismatic section bars at the set inside stiffening rib 150 of eight prismatic section bars.

As shown in figures 1 and 3; Further, said stiffening rib 150 is arranged between the section bar inboard and the section bar outside of eight prismatic section bars, and the section bar inboard and the section bar outside of eight prismatic section bars linked into an integrated entity; This structure can better be strengthened the stiffness and the resistance to bending of eight prismatic section bars; So that its bear big active force or with big movement velocity motion in, eight prismatic section bars can not produce the change of contracting, and improve eight prismatic section bar connection stability.Extremely shown in Figure 6 like Fig. 4; It is another embodiment of the utility model eight prismatic section bars, and the cross section outside 110 of this eight prismatic section bar is an octagon, and cross section internal layer 120 is circular; Eight faceted pebbles are provided with through hole 140; Itself and first embodiment's structural similarity is not just established stiffening rib, so repeat no more.

The utility model eight prismatic section bars; Because with the cross section arranged outside of section bar is Octagon; Make the utility model eight prismatic section bar stability improve greatly; And on eight faceted pebbles of eight prismatic section bars, all be provided with through hole, made things convenient for eight prismatic section bars to be connected with link, accurately to locate and accurately adjustment.

Should be understood that; The application of the utility model is not limited to above-mentioned giving an example; Concerning those of ordinary skills, can improve or conversion according to above-mentioned explanation, all these improvement and conversion all should belong to the protection domain of the utility model accompanying claims.
