Description
Technical field
The present invention relates to structural shape technical field, in particular to a kind of connecting unit of profile material with holes.
Background technique
With the continuous development of domestic automobile industry, industry competition is increasingly fierce, and user is higher and higher to the quality of automobile
Requirement, vehicle factor be keep product competitiveness, to vehicle update and new model release step constantly accelerate while, each vapour
Man, depot has also turned to attention the exploitation of measuring technique also in new process of constantly employing new technology.The development of manufacturing technology
It also be unable to do without measuring technique simultaneously, the two complements each other, and promotes mutually.New measuring technique constantly discloses the deficiency of new process
Place is allowed to further innovate and be transformed, becomes more perfect.The element of cubing, fixture as measuring technique,
The effect that production scene is played is more and more obvious, the single vehicle special gauge of tradition, fixture form be gradually unable to satisfy
It is required that more stringent requirements are proposed for economy and capability of fast response of the depot to cubing, fixture supplier products, so meeting
Multi-functional, flexibility, high efficiency, low cost directly determine the satisfaction of client.
Aluminum profile is as cubing, the foundation structure of fixture, it is not only the basis of cubing, fixture overlap joint dimensional accuracy, more
It is the guarantee for realizing high-precision flexibility reliability.Existing cubing, the foundation structure of fixture substantially use market standard slot
The foundation structure of formula industrial aluminum profile, standard hollow square tube aluminum profile and steel square tube section as cubing, by drilling and
The mode for being bolted or welding is fastened the foundation structure of limit, but weight weight, surface aesthetics are poor, can not repeat
Dismounting, welding position is not easy to be surface-treated.Therefore the frame body of installation cubing and fixture is built using standardized aluminum profile with holes
It is a kind of conducive to the solution stored and used.
In order to build fixed frame, we can use standardized profile with holes and matched connection component, connection component packet
A pair of of through-hole type connecting pin, a pair of of nut type connecting pin and four stay bolts, through-hole type connecting pin and nut type connecting pin is included to open
Equipped with axially across through-hole or threaded hole be used to pass through for stay bolt, through-hole type connecting pin and nut type connecting pin are all through band
In refine hole on the profile of hole, then it is fixed together tension with stay bolt.But the usual periphery of these connecting pins is cylinder,
Cooperation with refine hole is that unstable single line contacts, and axial lock clamp force cannot guarantee consistent with the axis of connector when locking.
It is therefore desirable to develop a kind of connection component of new construction to solve problem above.
Summary of the invention
The main purpose of the present invention is to provide a kind of connecting unit of profile material with holes, can accurately complete specific with holes
The assembling of profile.
The present invention is achieved through the following technical solutions above-mentioned purpose: a kind of connecting unit of profile material with holes, including a pair of of through-hole
Type connecting pin, a pair of of nut type connecting pin and four stay bolts；The through-hole type connecting pin and the nut type connecting pin cut open
Face axisymmetricly structure including the parallel side plane in left and right, is located below and lower plane and several circles perpendicular to side plane
Cambered surface, the symmetry axis that the stay bolt passes through connecting pin are fixed.
Specifically, being provided with above the connecting pin along symmetrical axisymmetric V-groove.
Further, the interior angle of the V-groove is in 120 °.
Specifically, the arc surface radius R having the same, the upper concyclic heart of arc surface, lower arc surface is total to another center of circle, two
A center of circle has eccentricity A.
By adopting the above technical scheme, the beneficial effect of technical solution of the present invention is:
The present invention pass through stay bolt can along symmetry axis, so ensure that bonding strength and stability, avoid connecting
Position opposite band hole profile generates deformation.

Specific embodiment
Invention is further described in detail combined with specific embodiments below.
Embodiment
As shown in Figures 1 to 4, the present invention is a kind of connecting unit of profile material with holes, including a pair of of through-hole type connecting pin 1a, one
To nut type connecting pin 1b and four stay bolts 4；The section of through-hole type connecting pin 1a and nut type connecting pin 1b are axisymmetricly tied
Structure, stay bolt 4 by across include the parallel side plane 11 in left and right, be located below and perpendicular to the lower plane of side plane 11 12 with
And several arc surfaces (upper arc surface 13 and lower arc surface 14), the symmetry axis that stay bolt 2 passes through connecting pin is fixed.Because of through-hole type
Side plane 11 and lower plane 12 are cut out above connecting pin 1a and nut type connecting pin 1b, so when stay bolt 4 tenses the two
When, periphery can form axisymmetric line at two with profile essence hole and contact.When profile essence hole 3 is bigger, contact point (figure
On irised out) be located at lower plane 12 and two sides lower arc surface 14 intersection；When profile essence hole 3 ' is smaller, contact point
(having irised out on figure) is located at the intersection of side plane 11 Yu lower arc surface 14.So when stay bolt 4 is locked, 2 total energy edge of stay bolt
Symmetry axis pass through, so ensure that bonding strength and stability, link position opposite band hole profile is avoided to generate deformation.
As shown in Figures 2 to 4, it is provided with above connecting pin 1a, 1b along symmetrical axisymmetric V-groove 15, V-groove 15
Interior angle be in 120 °.120 ° of V-grooves 15 guarantee the axial line of machine direction and threaded connector when processing through-hole or threaded hole
Alignment can prevent drill bit in boring procedure eccentric, guarantee machining accuracy, in assembly convenient for understanding connecting pin 1a, 1b assembly
Direction.
As shown in Figures 2 to 4, arc surface radius R having the same, the concyclic heart of upper arc surface 13, lower arc surface 14 are another altogether
One center of circle, two centers of circle have eccentricity A.So the section of connecting pin 1a, 1b are (equivalent here relative to the full circle of same radius R
The radius in profile essence hole) it is always less than normal, it avoids leading to not voluntarily adjust with profile essence hole excessively close-fitting.
Above-described is only some embodiments of the present invention.For those of ordinary skill in the art, not
Under the premise of being detached from the invention design, various modifications and improvements can be made, these belong to protection model of the invention
It encloses.
