Connecting bolt (4) has more than one.
Little alignment pin (5) has more than one.
Big alignment pin (6) has more than one.
Via a aperture is from the value that h is that little dowel hole c external diameter deducts via a external diameter.
Compared with prior art, the invention has the beneficial effects as follows:
1, two dowel hole axialities are ensured, it is ensured that part installation accuracy, it is to avoid part dislocation causes assembling difficulty, affects productive temp.
2, the axial displacement of alignment pin is effectively limited within the specific limits, it is to avoid alignment pin loses positioning action and causes the serious consequence of mechanical disorder improve machine reliability.
4, practical, reliable, can be used for the occasion of various needs.
3, simple for structure, processing is simple, and technique easily realizes.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
Embodiment 1, by increasing by a suitable positive stop lug boss in the middle of two pin-and-holes, and preferred each dimension combination, both can guarantee that the axiality of two pin-and-holes, moving axially within the acceptable range of two alignment pins can have been limited again.Realize being accurately positioned part, stopped to cause that correlated parts installation dimension is overproof because the rigging position of part own is inaccurate, affected entire machine quality.Avoid because alignment pin moves axially, use procedure causes losing efficacy in location, improve the reliability of location.It also avoid because part dislocation or alignment pin installation operational error cause assembling difficulty, affect productive temp.
Embodiment 2, one integrated positioning pin-and-hole structure of the present invention, including cylinder block (1), gear chamber (2), gear chamber cover (3), connecting bolt (4) (multiple), little alignment pin (5) (two), big alignment pin (6) (two).Gear chamber (2) is installed in cylinder block (1), gear chamber cover (3) is installed in gear chamber (2), and fixed by connecting bolt (4), gear chamber (2) is accurately located at cylinder block (1) by big alignment pin (6), and gear chamber cover (3) is accurately located in gear chamber (2) by little alignment pin (5).Dowel hole in gear chamber (2) adopts present configuration, two pin-and-holes and big dowel hole b and little dowel hole C coaxial inner conductor, medium design positive stop lug boss via a.Two coaxial dowel hole big dowel hole b and little dowel hole C medium design limited location boss are via a.Positive stop lug boss via a is the via between conducting big dowel hole b and little dowel hole C, and be projective table type through hole, via a is between big dowel hole b and little dowel hole C, via a is less than big dowel hole b and little dowel hole C, from the relatively small dowel hole C of h preferably (0.5 ~ 1), the hole width of via a is the part clamped width L value deducting (the little dowel hole C of big dowel hole b ten) in via a aperture.Via a boss height (relatively small pin-and-hole) h, h are preferably (0.5 ~ 1).Via a=L-(c+b), Big dowel hole b, little dowel hole C, via a aperture from h according to being embodied as case it needs to be determined that, various sizes combine.Big alignment pin (6) is straight pin 12X26(and diameter 12, length 26), little alignment pin (5) is straight pin 10X25(and diameter 10, length 25), part clamped width L=41, preferred: via a aperture is from h=0.5, big dowel hole b=14, little dowel hole C=12, then via a=L-(c+b)=13.By this group preferred size, big alignment pin (6), little alignment pin (5) move axially and are limited in smaller range, avoid alignment pin and lose positioning action to mobile excessive causing, improve reliability of positioning, without makeing mistakes in assembling process, also easily realizing in this kind of structural manufacturing process, processing is simple.
