Abstract
A feeding rod device of a bar feeder comprises a presser bar, a center shaft, a needle roller bearing, a center shaft core and clamps. The center shaft consists of a left center shaft unit and a right center shaft unit, the front end of the presser bar is tapered and threaded, and one end of the left center shaft unit, connected with the presser bar, is tapered and threaded and matched with the front end of the presser bar. The feeding rod device has small friction coefficient and is flexible in rotation and stable in use.
Description
Technical field
The utility model relates to the bar feeder, especially refers to a kind of feeding rod device of bar feeder.
Background technology
In the feeding rod device of existing bar feeder, generally comprise and give as security rod, axis, needle bearing, axis core etc., give as security rod and be connected dependence screwed separately with axis; When lathe turns round for a long time, give as security phenomenon excellent and that axis comes off because of shaking easy appearance, and in loosening; Axis core, nut, feed collet are retreated under the effect of thrust naturally, until nut directly with needle bearing produce rub till; So total is impaired, cause feeder normally not use.In addition, when assembling, needle bearing presses into machine, but because the unsettled no any back-up ring form in bearing right side, needle bearing is run out of because of vibration easily and is caused operational failure.The Chinese patent Granted publication number is CN2868545Y, and Granted publication day is that the utility model patent of 2007.02.14 provides a kind of bar feeder, comprises a feed pipe, is to be located at a board; One is connected in the signature rod that drives device; It can receive rotating shaft driving and with combined with transmission or separate; This design has comprised signature rod and rotating shaft; But do not take special connected mode to connect between the two, still exist give as security between rod and the axis break away from easily, the bad shortcoming of needle bearing stationarity.
Summary of the invention
The purpose of the utility model be overcome between the signature rod that exists in the prior art and the axis break away from easily, the bad problem of needle bearing stationarity, provide that a kind of coefficient of friction is little, rotation flexibly, use stable feeding rod device.
For realizing the purpose of the utility model; The technical solution of the utility model is: a kind of feeding rod device of bar feeder; Comprise and give as security rod, axis, needle bearing, axis core, feed collet; Axis comprises left axis and right axis, and said signature nose is tapering and adds shape of threads, and the end that left axis is connected with the signature rod has the tapering that cooperates with it to add screw thread.
Needle bearing, plane bearing and axis core are installed between said signature rod and the feed collet successively.
Said axis core one end aligns with the hole on the right axis, and steel ball is installed in the hole.
On the said left axis oil filler point is arranged.
The mode of taking tapering to add screw thread between said axis core and the feed collet is connected.
Compared with prior art, the utlity model has following beneficial effect:
1, add shape of threads because the signature nose is tapering, the end that left axis is connected with the signature rod has the tapering that cooperates with it to add screw thread, swelling each other between two taper angles, and fastness enhancing between signature rod and the axis is difficult for breaking away from.
2, owing between signature rod and the feed collet needle bearing, plane bearing and axis core are installed successively; Compared with prior art; A plane bearing has been installed on the right side of needle bearing more among the design, so needle bearing is not easy to break away from the axis core, has strengthened the structural stability of needle bearing.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: give as security rod 1, axis 2, left axis 21, right axis 22, needle bearing 3, axis core 4, feed collet 5, plane bearing 6, hole 7, steel ball 8, oil filler point 9.
The specific embodiment
Below in conjunction with Fig. 1 the utility model is done further detailed explanation:
Referring to Fig. 1; A kind of feeding rod device of bar feeder; Comprise and give as security rod 1, axis 2, needle bearing 3, axis core 4, feed collet 5; Axis 2 comprises left axis 21 and right axis 22, and excellent 1 front end of said signature is tapering and adds shape of threads, and the end that left axis 21 is connected with signature rod 1 has the tapering that cooperates with it to add screw thread.
Between said signature rod 1 and the feed collet 5 needle bearing 3, plane bearing 6 and axis core 4 are installed successively.
Said axis core 4 one ends align with the hole 7 on the right axis 22, and steel ball 8 is installed in the hole 7.
On the said left axis 21 oil filler point 9 is arranged.
The mode of taking tapering to add screw thread between said axis core 4 and the feed collet 5 is connected.
On the right axis 22 on the axis 2, be pressed into needle bearing 3; With axis core 4 plane bearing 6 of packing into, again axis core 4 is penetrated right axis 22 inside, make axis core 4 one ends align with the hole 7 on the right axis 22; Steel ball 8 is installed in the hole 7; Can add lubricating grease in 7 inside in the hole, both play lubrication, can prevent that again steel ball 8 from dropping.Be screwed into left axis 21 again, run out of, will give as security rod 1 at last and be connected with axis 2 to avoid axis core 4.Dry for preventing axis 2 internal grease, on left axis 21, oil filler point 9 is installed, can carry out oily through 9 pairs of feeding rods of oil filler point.Because excellent 1 front end of signature is tapering and adds shape of threads, the end that left axis 21 is connected with signature rod 1 has the tapering that cooperates with it to add screw thread, swelling each other between two taper angles, and fastness strengthens between signature excellent 1 and the axis 2, is difficult for breaking away from.Owing to give as security between rod 1 and the feed collet 5 needle bearing 3, plane bearing 6 and axis core 4 be installed successively; Compared with prior art; A plane bearing 6 has been installed on the right side of needle bearing 3 more among the design; So needle bearing 3 is not easy to break away from axis core 4, strengthened the structural stability of needle bearing 3.The utility model coefficient of friction is little, rotation is flexible, it is stable to use.
