Abstract
A kind of feeding lever apparatus of bar feeding machine, including giving as security rod, axis, needle bearing, middle shaft core, feed collet, axis includes left axle and right axis, and the signature nose is tapered to add shape of threads, and left axle has matched taper plus screw thread with giving as security one end that rod is connected.Coefficient of friction of the present invention is small, flexible rotation, use it is stable.
Description
Technical field
The present invention relates to the feeding lever apparatus of bar feeding machine, especially a kind of bar feeding machine.
Background technology
In the feeding lever apparatus of existing bar feeding machine, signature rod, axis, needle bearing, middle shaft core etc. are generally comprised, is given as security
Rod and axis connection rely solely on screw thread and tightened, during lathe long time running, are come off because shaking easily appearance signature rod and axis
Phenomenon, and loosen while, middle shaft core, nut, feed collet in the presence of thrust, naturally retreat, up to nut directly with
Untill needle bearing produces friction, so total is impaired, feeder is caused normally to use.In addition, in assembling, rolling
Needle bearing is pressed into machine, but is due to that bearing right side is hanging without any back-up ring form, needle bearing it is easy because
Vibration is run out of and causes to use failure.Chinese patent Authorization Notice No. is CN2868545Y, and authorized announcement date is 2007.02.14
Utility model patent provide a kind of bar feeding machine, comprising a feed pipe, be provided at a board；One is connected to driving device
Signature rod, it can be combined or separated with transmission device by the driving of rotating shaft, and the design contains signature rod and rotating shaft, but both it
Between do not take special connected mode to be attached, however it remains be easily separated between signature rod and axis, needle bearing it is solid
Qualitative bad shortcoming.
The content of the invention
The purpose of the present invention be overcome given as security present in prior art between rod and axis be easily separated from, needle bearing is fixed
Property it is bad the problem of there is provided a kind of coefficient of friction is small, flexible rotation, use stable feeding lever apparatus.
To realize the purpose of the present invention, technical solution of the invention is：A kind of feeding lever apparatus of bar feeding machine,
Including giving as security rod, axis, needle bearing, middle shaft core, feed collet, axis includes left axle and right axis, and the signature nose is tapered
Plus shape of threads, there is matched taper plus screw thread one end that left axle is connected with signature rod.
Needle bearing, plane bearing and middle shaft core are sequentially installed between the signature rod and feed collet.
Described middle shaft core one end is alignd with the hole on right axis, and steel ball is provided with hole.
There is oil filler point on the left axle.
The mode of taper plus screw thread is taken to connect between the middle shaft core and feed collet.
Compared with prior art, the invention has the advantages that：
1st, due to giving as security, nose is tapered to add shape of threads, and left axle has matched taper plus spiral shell with giving as security one end that rod is connected
Mutual swelling between line, two taper angles, giving as security fastness between rod and axis strengthens, and is not easily disconnected from.
2nd, needle bearing, plane bearing and middle shaft core are sequentially installed with due to giving as security between rod and feed collet, compared with prior art
For, a plane bearing is mounted with the design more on the right side of needle bearing, so needle bearing not readily disengages from middle shaft core,
Enhance the structural stability of needle bearing.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
In figure：Signature rod 1, axis 2, left axle 21, right axis 22, needle bearing 3, middle shaft core 4, feed collet 5, plane bearing 6,
Hole 7, steel ball 8, oil filler point 9.
Embodiment
Below in conjunction with Fig. 1, the present invention is further detailed explanation：
Referring to Fig. 1, a kind of feeding lever apparatus of bar feeding machine, including give as security rod 1, axis 2, needle bearing 3, middle shaft core 4, feed collet
5, axis 2 includes left axle 21 and right axis 22, and signature rod 1 front end is tapered to add shape of threads, and left axle 21 is connected with giving as security rod 1
There is matched taper plus screw thread the one end connect.
Needle bearing 3, plane bearing 6 and middle shaft core 4 are sequentially installed between the signature rod 1 and feed collet 5.
Described one end of middle shaft core 4 is alignd with the hole 7 on right axis 22, and steel ball 8 is provided with hole 7.
There is oil filler point 9 on the left axle 21.
The mode of taper plus screw thread is taken to connect between the middle shaft core 4 and feed collet 5.
Needle bearing 3 is pressed on right axis 22 on axis 2, middle shaft core 4 is loaded into plane bearing 6, then by middle shaft core 4
Penetrate inside right axis 22 so that middle one end of shaft core 4 is alignd with the hole 7 on right axis 22, and steel ball 8 is provided with hole 7, can be in hole
7 inside add lubricating grease, both play lubrication, can prevent steel ball 8 from dropping again.Left axle 21 is screwed into again, to avoid axis
Core 4 is run out of, and will finally be given as security rod 1 and is connected with axis 2.To prevent the internal grease of axis 2 from drying up, oiling is installed on left axle 21
Hole 9, can be carried out oily by oil filler point 9 to feeding rod.Due to giving as security, the front end of rod 1 is tapered to add shape of threads, left axle 21
Have mutual swelling between matched taper plus screw thread, two taper angles with giving as security the one end that is connected of rod 1, give as security rod 1 and axis 2 it
Between fastness strengthen, be not easily disconnected from.Needle bearing 3, plane bearing 6 and axis are sequentially installed with due to giving as security between rod 1 and feed collet 5
Core 4, for prior art, is mounted with a plane bearing 6, so needle roller axle more in the design on the right side of needle bearing 3
Hold 3 and not readily disengage from middle shaft core 4, enhance the structural stability of needle bearing 3.Coefficient of friction of the present invention is small, flexible rotation, make
With stabilization.
