Embodiment 1

[0024] Embodiment 1: Referring to Figures 1, 3, and 4, processing tools 4 are respectively arranged on the CNC rotary turret 5, and a pulling jig 6 with a "Y" fork opening is fixed by a fixed block 3, wherein the opening is aligned with the machine tool The axis is vertical, the thickness of the clamp is 3mm, and the opening is at an angle of 30-80°. After the parts are processed, move the tool forward to the position to be cut off, process a shallow ring groove, rotate and move the turret, make the pulling jig radially snap into the processing shallow groove (Figure 3, 4), and release the 2 clamps of the bar material Holder 1, retract the turret in the axial direction and pull out the material at a fixed length, lock the bar material holder 1, move the turret to radially withdraw from the jig, turn the turret, and cut the processed parts according to the processing slot, according to the original setting The program machines the next part. The above-mentioned fixed-length dr...

Embodiment 2

[0025] Embodiment 2: Referring to Figures 2, 3, and 4, as in Embodiment 1, a machining tool 4 and a pulling fixture 6 are respectively provided on the numerically controlled knife row turret 5 . After the parts are processed, move the turret to cut off the processed parts, move the turret, and process a shallow ring groove at the place where the next part has a radial machining allowance, and move the turret to make the pulling clamp radially snap into the processing Shallow slot (Fig. 3, 4), loosen bar 2 holder 1, move the turret axially to pull out the material at a fixed length, lock the bar holder 1, move the turret to radially exit the fixture, move the turret , process the next part according to the original setting program. The above-mentioned fixed-length drawing process is realized by compiling a macro program separately and setting the calling program in the original program.

Embodiment 3

[0026] Embodiment 3: Add a pulling jig 6 with a U opening on the turret 5 . After the parts are processed, move the turret so that the pulling jig radially snaps into the upper step of the part, loosen the bar holder, move the turret axially to pull out the material at a fixed length, lock the bar holder, and move the knife The turret exits the jig radially, moves the turret, cuts off the processed parts, moves the turret, and processes the next part according to the original setting program. The turret can be the rotary turret in Embodiment 1, or the row-type turret in Embodiment 2, and the movement of the turret is determined according to the form of the turret.

[0027] In addition, the drawing bar can also be set on the turret, such as a spring-type collet, through the clamp-type drawing.

Abstract

The present invention is improved automatic bar stock feeding process and unit for numerically controlled lathe. The present invention features that the automatic bar stock feeding unit includes one bar stock fixture one part fixture set on the numerically controlled multiple site cutter tower; and the programmable automatic bar stock feeding process includes the steps of shifting or rotating the numerically controlled multiple site cutter tower, fixing length and feeding bar stock, fixing the bar stock for machining and releasing the fixture for the next part machining. The present invention has automatic machining, low labor strength, high machining efficiency and other advantages.

Description

technical field [0001] The invention relates to the improvement of the automatic feeding method and device for the bar material of the turning processing part of the numerical control lathe. Background technique [0002] Although the CNC lathe can automatically complete the machining of the part car at one time according to the set program. However, the automatic completion of the turning process is only from the beginning of the part processing to the completion of the turning process, and the feeding of the parts processed from the bar one by one still needs to be done manually. That is, every time a part is processed (such as a radio frequency coaxial cable connector), it is necessary to open the door of the lathe, loosen the bar holder, manually pull out the material, measure and adjust the length, and lock the bar holder to clamp the bar , close the door for the next same turning process. Every time a part is processed, the above-mentioned low-efficiency manual and co...
