Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Represented by Fig. 1-Fig. 4 is a kind of powder metallurgy water pump flange, hereinafter referred to as flange.This flange is by the once compressing monolithic construction of powder metallurgy die by powdered metallurgical material.
As Figure 1-Figure 4, this flange comprises body 1, center hole 4, tapped through hole 2, round boss 3, Y shape boss 5, wherein:
Rounded or the triangle of the profile of body 1.Chamfering I 1-1 is provided with at the upper-end surface cylindrical of body 1.
Be provided with round boss 3 in the center portion of body 1 upper-end surface, the upper-end surface cylindrical of this round boss 3 is provided with chamfering IV 3-2, and this chamfering IV 3-2 is 0o ~ 60o.The location when cylindrical of this round boss 3 is for assembling.
Body upper-end surface bottom round boss 3 is provided with annular clearance groov 1-2.
Body 1 is evenly distributed in along same three tapped through holes 2 be looped around around round boss 3.Jointing place between tapped through hole 2 and body 1 lower end surface is provided with chamfering II 2-1, and the jointing place between tapped through hole 2 and body 1 upper-end surface is provided with chamfering III 2-2.This tapped through hole 2 is for clamping bolt.
Round boss 3 cylindrical and the position corresponding with a tapped through hole 2 is provided with concaved circular cambered surface 3-1 in; Like this, three tapped through hole 2 correspondences are provided with three interior concaved circular cambered surface 3-1.The effect of three interior concaved circular cambered surface 3-1 is: when preventing from assembling, bolt is interfered.
Body 1 and round boss 3 run through and has center hole 4.At the center hole part of center hole more than step 4-1 with tapering, the axial angle in its conical central hole face is α=0o ~ 60o.Jointing place between center hole 4 and body 1 lower end surface is provided with chamfering V 4-2.This center hole 4 is for connecting shaft-like bearing.
As shown in Figure 3, the lower end surface of body 1 is provided with Y shape boss 5, this Y shape boss 5 is with three pawls, and these three pawls are centered by center hole 4 and be uniformly distributed.Three tapped through holes 2 pass from three of Y shape boss 5 pawls accordingly, and namely a tapped through hole 2 passes from a pawl of Y shape boss 5.
The effect of Y shape boss 5 is: the effective length of thread engagement lengthening three tapped through holes 2 and center hole 4, and can also weight reduction, saves raw material.
