Embodiment Construction

[0014] The following combination figure 1 The present invention is described in further detail:

[0015] see figure 1 , a feeding rod device of a bar feeder, comprising a push rod 1, a central shaft 2, a needle bearing 3, a central shaft core 4, and a material clamp 5, and the central shaft 2 includes a left central shaft 21 and a right central shaft 22, the The front end of the push rod 1 is tapered and threaded, and the end of the left central axis 21 connected with the push rod 1 has a taper and thread matched therewith.

[0016] Needle roller bearings 3 , plane bearings 6 and central axis cores 4 are sequentially installed between the press rod 1 and the material holder 5 .

[0017] One end of the central axis core 4 is aligned with the hole 7 on the right central axis 22, and a steel ball 8 is installed in the hole 7.

[0018] An oil injection hole 9 is arranged on the left center shaft 21 .

[0019] The central axis core 4 and the material holder 5 are connected in a...

Abstract

A feeding rod device for a rod feeding machine comprises a pressing rod, a middle shaft, a needle roller bearing, a middle shaft core and a material clamp. The middle shaft comprises a left middle shaft body and a right middle shaft body. The front end of the pressing rod is in a taper and thread shape. The end, connected with the pressing rod, of the left middle shaft body has a taper and a thread which are matched with the left middle shaft body. The feeding rod device for the rod feeding machine is small in friction coefficient, flexible in rotation and stable in use.

Description

technical field [0001] The invention relates to a bar feeding machine, in particular to a feeding rod device of the bar feeding machine. Background technique [0002] The feeding rod device of the existing bar feeder generally includes a pressing rod, a central shaft, a needle roller bearing, a central shaft core, etc. The connection between the pressing rod and the central shaft is tightened by threads alone. When the lathe is running for a long time, it is easy to cause the rod And the phenomenon that the center shaft falls off, and at the same time of loosening, the center shaft core, nut, and material clip will naturally retreat under the action of thrust until the nut directly rubs against the needle bearing, so the entire structure is damaged, causing the feeder Does not work properly. In addition, during assembly, the needle roller bearing is riveted in by machine, but since the right end surface of the bearing is suspended without any form of retaining ring, the nee...
