The vertical guide rail 16 is arranged on the seat body 11, one side of the adjusting plate 12 is clamped on the vertical guide rail 16 and is connected with the adjusting plate 12 through a servo motor, and the servo motor is started to enable the adjusting plate 12 to vertically move along the vertical guide rail 16.

The automatic feeding machine 7 of the present embodiment is a PRO 326 automatic feeding machine 7 available from a commercial source, and the automatic feeding machine 7 and the main shaft mechanism are partially shown in fig. 1 and 2, and a specific configuration diagram is not shown. A feeding channel is arranged in the automatic feeding machine 7, a main shaft chuck 81 is arranged at the front end of the main shaft mechanism, a longitudinal through hole is formed in the main shaft chuck 81, and the longitudinal through hole of the main shaft chuck 81 is communicated with the feeding channel of the automatic feeding machine 7. The tube and bar material 6 is first placed in the feeding channel of the automatic feeding machine 7, and the automatic feeding machine 7 pushes the tube and bar material 6 toward the main shaft chuck 81 until the tube and bar material 6 extends out of the main shaft chuck 81.

An inner cutter 13 is installed at the rear end of the adjusting plate 12, an outer cutter 14 is installed at the front end of the adjusting plate 12, and a plurality of inner cutters 13 and outer cutters 14 are provided. In this embodiment, the longitudinal direction of the horizontal guide rail 42 is horizontal, the longitudinal direction of the automatic feeder 7 is vertical, and the longitudinal direction of the vertical guide rail 16 is vertical. The front end of the pipe rod 6 in the spindle chuck 81 is processed by an inner cutter 13 at the rear end of the adjusting plate 12: the spindle grip 81 does not move, but the inner tool 13 is aligned with the tubular bar 6 in the spindle grip 81 by moving the adjustment plate 12, and different inner tools 13 can perform different shapes on different positions of the tubular bar 6.

As shown in fig. 1, 2 and 3, after the inner cutter 13 finishes processing the front end of the tube and bar 6 in the spindle chuck 81, the tube and bar 6 is pushed forward by the automatic feeder 7 for a certain distance; then, the auxiliary shaft mechanism is started, and an auxiliary shaft chuck 35 of the auxiliary shaft mechanism clamps the front end of the tube bar 6; and moving the adjusting plate 12, and cutting the rear end of the tube bar 6 by using a cutter 15 on the adjusting plate 12, wherein the length of the cut tube bar 6 is the length required by the insulating sleeve of the spark plug.

A servomotor is connected to the base 32 and is activated to cause the base 32 and the auxiliary shaft seat 33 to move together laterally along the auxiliary shaft guide rails 31. A secondary shaft chuck 35 is arranged at the rear end of the secondary shaft seat 33, a guide pipe 34 is arranged at the front end of the secondary shaft seat 33, through holes are formed in the guide pipe 34 and the secondary shaft chuck 35, and the through holes in the guide pipe 34 are communicated with the through holes in the secondary shaft chuck 35.

Fixed processing agency includes fixing base 21 and mounting panel 22, and the front end of fixing base 21 is provided with mounting panel 22, is provided with fixed cutter 23 on the mounting panel 22. After the counter shaft chucks 35 clamp the cut-off tube bar 6, the counter shaft chucks 35 move to the fixed cutter 23 of the fixed base 21 along the counter shaft guide rails 31 in the transverse direction. Since the height of the counter chuck 35 is the same as that of each fixed cutter 23, when the fixed cutter 23 machines the rear end of the tube or bar 6 in the counter chuck 35, the position of the fixed cutter 23 does not move, but the counter chuck 35 only needs to move in the transverse and longitudinal directions, does not need to move in the vertical direction, and then the counter chuck 35 rotates the tube or bar 6 to machine. The shape of the rear end of the bar 6 is determined by the shape of the edge of the fixed cutter 23, and the depth of the machining is controlled by the distance the counter chuck 35 moves longitudinally.

After the tube rod 6 in the counter chuck 35 is finished, the automatic feeder 7 pushes the tube rod 6 in the counter chuck 35 into the guide tube 34, specifically: after the next tube and bar 6 in the main shaft chuck 81 is processed, the auxiliary shaft chuck 35 will move to the position aligned with the main shaft chuck 81, and the automatic feeder 7 will push the tube and bar 6 forward for a distance; at this point, the tube rod 6 in the primary collet 81 will push the tube rod 6 in the secondary collet 35 forward into the guide tube 34. When the automatic feeding machine 7 pushes the tube and bar 6 with a length of 2-3 meters forward again and again, the cut and processed tube and bar 6 in the guide tube 34 is extruded out of the guide tube 34, and then falls out of the guide tube 34 and falls into a box beside the guide tube 34.

In order to prevent the scraps and the strip-shaped filament scraps generated in the processing from being wound and accumulated at the inner cutter 13, the outer cutter 14 and the fixed cutter 23 when the tube bar 6 is processed, the scrap blowing tube 5 is further arranged at the inner cutter 13, the outer cutter 14 and the fixed cutter 23 in the embodiment, and the scraps and the strip-shaped filament scraps generated in the processing are blown away. Both the fixed cutter 23 and the outer cutter 14 can machine the rear end of the tube or bar 6 in the countershaft chuck 35, and in this embodiment, only the fixed cutter 23 is used to machine the rear end of the tube or bar 6. In this embodiment, each servo motor is connected to a PLC, and the PLC controls each servo motor to work in cooperation. Through PLC control, the main shaft mechanism and the auxiliary shaft mechanism can asynchronously and simultaneously process two ends of a product, thereby achieving double processing efficiency of a single product. In this embodiment, the front end of each component is directed from the automatic feeding machine 7 to the auxiliary shaft seat 33, and the rear end is opposite to the front end.

It will be apparent that modifications and variations are possible without departing from the principles of the invention as set forth herein.
