In the processing process of the main shaft 2, the long material rod is usually locked by a clamping piece on the main shaft 2, so as to play a role in fixing. Of course, for the setting mode of the feeder, reference may be made to the prior art, and stable feeding of the long rod may be achieved, which is not described herein. Other auxiliary automation control functions for the feeder are not described in detail herein.

The auxiliary spindle 3 is slidably disposed on the machine tool body 1 and is located at a side of an extending end of the long rod, and is used for clamping the long rod, the clamping end of the main spindle 2 is opposite to the clamping end of the auxiliary spindle 3, and the sliding auxiliary spindle 3 has a certain position, so that the axis of the sliding auxiliary spindle 3 is coaxial with the axis of the main spindle 2.

Specifically, the auxiliary spindle 3 may be slidably disposed on the machine tool body 1 by means of a screw and a slide rail, but in order to satisfy the machining conditions, it is necessary to slidably dispose the auxiliary spindle 3 in two directions, i.e., laterally and longitudinally, so as to satisfy the machining of the product to be machined by the auxiliary tool post; and two sets of screw rods and sliding rails are needed for realizing the two sliding directions in the transverse direction and the longitudinal direction, referring to fig. 3, two sets of screw rod sliding rails can be arranged at the lower part of the auxiliary main shaft 3 and are arranged in a high-low lamination mode, and the two sliding directions are not mutually influenced, so that the processing conditions are met.

The turret includes a main turret 4 for processing a product held by the main spindle 2 and a sub-turret 5 for processing a product held by the sub-spindle 3. The positive turret 4 can also slide along the axial direction and the radial direction of the positive main shaft 2 in the arrangement manner, wherein the axial direction and the radial direction of the positive main shaft 2 respectively correspond to the transverse direction and the longitudinal direction; specifically, the positive turret 4 includes a fixing frame and a first turning tool 41 provided on the fixing frame, and the first turning tool 41 is capable of processing a product to be processed held by the positive spindle 2; the bottom of the fixing frame is slidably arranged on the machine tool main body 1 through a screw rod and a sliding rail, and the specific sliding mode can refer to the sliding mode of the auxiliary main shaft 3, which is not described in detail herein.

Of course, other numbers of cutters are possible for a particular number of cutters, including but not limited to the embodiments set forth above, and are not described in detail herein.

In addition, a swinging receiver 7 is further arranged at the lower side of the auxiliary main shaft 3, the receiver 7 can be arranged in a swinging way through a Z-shaped structure, namely, two ends of the Z-shaped structure are respectively connected with the auxiliary main shaft 3 and the receiver 7, and the Z-shaped edge on the auxiliary main shaft 3 is used as a rotating shaft to rotate, so that the swinging of the receiver 7 is realized. Of course, the arrangement of the receiver 7 here does not affect the movement effect of the secondary spindle 3 and the machining efficiency of the two tool towers. On the basis, a receiver 7 is arranged on the machine tool main body 1 along with the auxiliary main shaft 3 in a sliding way and is used for receiving products processed by the main shaft 2 and/or the auxiliary main shaft 3.

In addition, since the receiver 7 is located below the sub spindle 3 after the completion of the processing and can move along with the sub spindle 3, the receiver 7 can receive a product processed by the main spindle 2 or the sub spindle 3, and then swing above the conveyor belt 8 and convey the product to the outside of the machine tool main body 1 through the conveyor belt 8. It should be noted that, the feeder of this application can arrange one or more long material stick simultaneously, but only send out one at a time to in the course of working, through cutting off long material stick, thereby make long material stick after accomplishing one section processing, can continuously push, thereby carry out next processing work, greatly improve work efficiency, guarantee machining precision simultaneously.
