(5) specific embodiment

Referring to Fig. 1, the utility model relates to valve inside core cap and mills limit autofeed device, valve inside core cap autofeed adopts vibrating bunker, the diameter of vibrating bunker is φ 220mm, highly be 60mm, sunken bottom, material is a stainless steel, and power of electromagnet is 45W, input AC, voltage 220V, reach trouble free service voltage 36V by the power transformer transformation, be provided with transformation coil and transformation by-pass cock (potentiometer) in the vibrating bunker, can reach the adjusting of vibration force size like this: in hopper, sort automatically through the vibration back for making the core cap, enter the material pore by the material road, adopted following method:

The design in a, long material road: core cap 1 enters vibrating bunker 2 backs by vibration, become vertical array, the any plane of core cap contacts with vibrating bunker 2 bottoms, and design has the long material road 3 that spirals and climb along the vibration material headwall in the vibrating bunker 2, and long material is the plane at the bottom of 3 roads, road, current for the core cap, long material road launches the long 550mm in back, wide 10mm, and the angle that long material road and hopper bottom surface upwards form is 4 °, the core cap is vertical array under the vibrating bunker effect, moves upward along long material road.See Fig. 4.

B, the design in short material road: vertically disposed core cap expects to enter short material road 4 behind the road by long, the original arrangement mode of core cap for a change, make it to become transversely arranged, short material road 4 is designed to the long material of the short material channel ratio low 3mm in road with the interface in long material road 3, short material road launches the long 170mm in back (be about vibrating bunker circular arc 1/4), wide 8mm, short material road is horizontally disposed along the vibration material headwall, short material road is parallel with the hopper bottom surface, short material road is arc surface and arranges, short material road circular-arc bottom face is that radius is the semicircle of 3mm, the dark 2mm of circular arc is when vertically disposed core cap moves to long material road junction, road, because long, short material has difference of height between the road, the core cap changes original vertical array when falling into short material road, becomes transversely arranged.Under the effect of vibrating bunker, the core cap continues to move to the material mouth of pipe along short material road.See Fig. 5.

C, core cap are in short material road during transversely arranged motion, the two ends that the core cap is arranged are nondeterministic statement, according to the direction of motion analysis of transversely arranged core cap in short material road, can produce two kinds of phenomenons, a kind of be the big nose end of core cap towards the direction of motion, a kind of is that core cap small bore end is towards the direction of motion, and the big nose end of core cap that advances feeding pipe 6 must make progress, could guarantee that like this core cap falls behind the feeding pipe, enter into manipulator and keep a direction, thereby obtain the core cap is milled the position on limit.Do following design for addressing the above problem: short material road end promptly enters expects that mouth of pipe 30mm place before is 20 ° of angles and has a down dip, to guarantee that the core cap moves to the material mouth of pipe by the inclined-plane smoothly under the vibration force effect, and make core cap macropore be 20 ° of inclinations, above the material mouth of pipe orientation is housed and colludes 5, orientation is colluded the end face radial dimension and is designed between core cap macropore stomidium footpath and core cap small bore end aperture.The core cap can produce following two kinds of situations when moving to the material mouth of pipe, when core cap small bore end walks to the material mouth of pipe towards the direction of motion above, when doing the movement of falling object downwards, running into orientation colludes, be subjected to orientation to collude the effect of impact force, change the direction of motion and drop down onto outside the material mouth of pipe, get back in the vibrating bunker.When the big nose end of core cap walks to material mouth of pipe top towards the direction of motion, when doing the movement of falling object downwards, running into orientation colludes, orientation is colluded the macropore that enters the core cap, collude because of orientation and to be 45 ° of inclinations, can not collude firm core cap, the core cap direction of motion is changed, produce the downward movement of falling object of the little stomidium of core cap and enter the material mouth of pipe that has designed.See Fig. 6.
