[0037] In this embodiment, the processing efficiency of the device for small metal parts with polygonal columns on the top is higher than that of the traditional horizontal lathe; the device can effectively improve the continuous processing efficiency of small metal parts. Compared with the traditional device, the device can achieve the effect of automatic feeding through the structure of the slide 12, thereby reducing labor costs. When the device is in a working state, multiple groups of metal parts are arranged above the slide 12, so as to achieve the effect of automatic feeding. The combination of the telescopic rod 14 and the rack 15 can effectively improve the accuracy of the device in controlling the rotating blocking member 13, thereby controlling the unloading of metal raw materials by rotating the blocking member 13. When the metal raw material moves When it reaches the processing platform 11, the rotating motor 8 is driven to slide down through the mounting bracket 7, so that the sleeve 9 contacts the top of the metal raw material; and it is squeezed downward, and the turntable 18 slides down during the pressing process, and the spring 20 contracts. When it is pressed to the appropriate position, the cutting telescopic rod 21 and the cutting head 22 are extended and retracted outward, and the cutting head 22 achieves the pinning effect when the sleeve 9 drives the metal part to rotate at a high speed. The turntable 18 can provide reverse support for the metal raw material, thereby preventing the metal raw material from loosening downward. When the processing is completed, the metal part moves upward, and the processed metal part is pushed into the collecting bucket 10 through the fall of the next metal raw material.

[0038] Multiple groups of metal raw materials can be stored in the slide groove 12. Before starting processing, the rotating blocking member 13 is in an outward protruding state to block the metal raw materials. The telescopic rod 14 drives the rack 15 to slide linearly, and the sliding of the rack 15 drives multiple groups of fan gears 16 to rotate. The fan gear 16 drives the rotating shaft 17 to rotate, and the top of the rotating shaft 17 drives the rotating blocking member 13 to rotate, so that the rotating blocking member 13 rotates and contracts to both sides to release the effect of the rotating blocking member 13 blocking the raw materials. At this time, the metal raw materials slide down onto the processing platform 11.

[0039] The threaded rod 4 is driven to rotate by the lifting motor 3, and the threaded rod 4 drives the lifting bracket 5 to slide vertically linearly. The lifting bracket 5 drives the rotating motor 8 to move up and down, and the sleeve 9 is driven to rotate by the rotating motor 8, thereby achieving the effect of the sleeve 9 rotating downward, so that the sleeve 9 is connected with the top of the metal raw material and drives the metal raw material to rotate.

[0040] By rotating the turntable 18 and the support rod 19, the metal raw material can rotate horizontally on the top of the turntable 18. The turntable 18 and the support rod 19 are made to slide downward by the spring 20 when the sleeve 9 is pressed downward. At this time, the spring 20 is in a compressed state. The cutting telescopic rod 21 drives the cutting head 22 to slide linearly, so that the cutting head 22 can contact the side of the metal raw material to complete the cutting processing effect.

[0041] The threaded rod 4 rotates in the opposite direction to drive the lifting bracket 5 to slide upward, so that the turntable 18 is at the same height as the processing platform 11. At this time, by rotating the rotating blocking member 13, another metal raw material is released to fall, and the processed metal raw material can be hit into the collecting bucket 10.

[0042] Embodiment 2

[0043] like Figure 1-Figure 7 As shown, a CNC lathe proposed by the utility model, compared with the first embodiment, in this embodiment, a guide plate is provided on the bottom side of the bottom of the slide groove 12, and multiple groups of guide plates are symmetrically arranged on both sides of the bottom of the slide groove 12, and the guide plates are facing the direction of the turntable 18.

[0044] The structure of the guide plate can effectively limit the sliding metal raw material, so that the metal raw material can accurately enter the correct position on the turntable 18, thereby ensuring the accuracy of the sleeve 9 during the downward pressing process.
