Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the feeding rod piece for automatic lathe described in the utility model.
Fig. 2 is the enlarged structure schematic diagram in Fig. 1 at A.
Specific embodiment
The utility model is described in further detail with attached drawing combined with specific embodiments below.
As shown in Figure 1 and Figure 2, a kind of feeding rod piece for automatic lathe, comprising: mobile jib 1, on the front end face of mobile jib 1
It is provided with a mounting hole 2 coaxially arranged with mobile jib 1, the rear portion of feed point 3 is plugged in mounting hole 2 by rotation support mechanism
In, enable the rotation on the front end of mobile jib 1 of feed point 3, is placed with one for supporting for feed point 3 in the bottom of mounting hole 2
The thrust steel ball 4 leaned on, thrust steel ball 4 here are equivalent to thrust bearing, thrust steel ball 4 feed point 3 is supported it is same
When big rotational resistance can not be brought to feed point 3, in the present embodiment, the bottom surface of mounting hole 2 is the tapered surface being recessed inwardly,
Tapered surface can position thrust steel ball 4；The material hole for clamping bar is provided on the front end face of feed point 3
31, expect that the rotation center of the axis and feed point 3 in hole 31 is coaxially arranged, bar is inserted into material hole 31 by one end and is clamped in
On feed point 3, a driving piece 5 with holes is provided on the side wall at 1 rear portion of mobile jib.Bar, which is clamped rotate by collet chuck, to be added
In working hour, feed point 3 can and then bar rotate together, to not interfere the processing of bar.One end of nylon wire passes through hole and is tied to drive
After on movable plate 5, charging driving device can make the feeding forward of feeding rod piece by pullling nylon wire.
In the present embodiment, the structure of rotation support mechanism includes: two inner sleeves being fastened in mounting hole 2 21,
Two inner sleeves 21 time interval in mounting hole 2 is arranged, and the rear portion of feed point 3 is sequentially inserted into two inner sleeves 21, until sending
3 rear end of material head can lean with thrust steel ball 4, and gap surround 3 rear sidewall of feed point surrounded between two inner sleeves 21
On be provided with the annular groove 22 that the groove face that a circle is arranged around 3 rear portion of feed point is arc, be placed in annular groove 22
Several anti-avulsion steel balls 23, each anti-avulsion steel ball 23 are located in the gap between two inner sleeves 21, and two inner sleeves 21
Between gap can also to anti-avulsion steel ball 23 carry out front and back limit, thus each anti-avulsion steel ball 23 can to feed point 3 carry out front and back
