Embodiment Construction
[0011] Such as figure 1 As shown, the valve guide automatic drilling device of the present invention includes an automatic feeding mechanism 10 , a delivery track mechanism 20 and an automatic drilling mechanism 30 . The automatic feeding mechanism 10 is used for sorting and feeding the workpiece 0, that is, the valve guide, the conveying track mechanism 20 is used for loading and unloading the workpiece 0 during processing, and the automatic drilling mechanism 30 is used for automatic drilling of the workpiece 0. For hole processing, there is a boss at one end of workpiece 0, so the weight of both ends of workpiece 0 is unbalanced.
[0012] Such as figure 1 As shown, the automatic feeder 10 includes a vibrating upper material cylinder 11, which has a vibrating device (not shown in the figure) under the vibratory upper material cylinder 11, and a vibrating upper material cylinder 11 is provided with a spiral track from bottom to top 12. The width of the track 12 matches the ...

The invention relates to the technical field of automobile part machining, in particular to an automatic valve guide pipe drilling device. Compared with the prior art, the automatic valve guide pipe drilling device comprises an automatic feeding mechanism, an automatic ejector mechanism and an automatic drilling mechanism, two groups of drilling devices are adopted, one group is entry guide drilling devices, namely, one guide hole is drilled in advance by a large drill bit, the other group is through hole drilling devices, through holes are directly drilled based on the guide hole by the through hole drilling devices, so that through hole accuracy and stability can be ensured, square rail groove entry circulation feeding and discharging are adopted, and the automatic valve guide pipe drilling device has the advantages of high automation degree, high machining efficiency, stable machining precision, high product qualification rate and the like.
Description
technical field [0001] The invention relates to the technical field of machining equipment for auto parts, in particular to an automatic drilling device for valve guides. Background technique [0002] The valve guide is the guide device for the valve of the automobile engine. The valve guide guides the valve and transfers the heat on the valve stem to the cylinder head through the valve guide. The operating temperature of the valve guide is also relatively high, about 200°C. When moving in the duct, it is lubricated only by the oil splashed out of the valve mechanism, so it is easy to wear, so it is often made of self-slip ductile iron or powder metallurgy materials to make separate parts, and pressed into the cylinder head with a certain interference. In the valve guide seat hole, prevent falling off. In order to prevent the valve guide from loosening, some engines use a snap ring to fix and position the guide tube. The outer cylindrical surface of the valve guide is proces...
