An automatic drilling and tapping device for a lathe comprises a support, a first support plate and a second support plate, wherein the support is connected with a saddle, and the first support plate and the second support plate are mounted on two sides of a saddle beam. The upper portions of the first support plate and the second support plate are connected through a first support rod and a second support rod; a first vertical plate and a second vertical plate are parallelly mounted on the first support rod and the second support rod respectively and are connected together; a positioning shaft of a stepped structure is mounted in a through hole on the upper portion of the first vertical plate; an eccentric wheel is mounted at a small-diameter end of the positioning shaft; a handle is connected onto the eccentric wheel; a resetting mechanism is sleeved at the small-diameter end of the positioning shaft; a large-diameter end of the positioning shaft extends into a through hole at an arc end of a segment; a horizontal shaft is mounted in a central hole of the segment; and an extending end of the horizontal shaft is mounted in a mounting hole of the second vertical plate. Compared with the prior art, the automatic drilling and tapping device has the advantages that repeated clamping of a center drill, a twist drill and a screw tap is omitted, tools can be changed only by turning the segment, and operation is more convenient.
Description
Technical field: [0001] The invention relates to a component for a lathe, in particular to an automatic drilling and tapping device for a lathe. Background technique: [0002] When processing parts on small and medium-sized ordinary lathes, if there is a hole in the center of the end face of the processed part, it needs to be processed. The usual processing method is to clamp the twist drill bit on the drill chuck with a tapered shank, then install the tapered shank in the sleeve of the tailstock, and drill the workpiece by turning the handwheel on the tailstock. This method of operation is fast and slow, the feed is uneven, and it is not easy to achieve the best feed. The production efficiency is low, and the labor intensity of the workers is relatively high. [0003] In addition, when drilling, usually a shallow hole is drilled on the end face of the part with a center drill for positioning, and then drilled with a twist drill. In general, both the center drill and the ...
