[0002] Currently, for the cutting of cylindrical blanks or multi-piece cutting in the traditional process, a single cutting tool is mostly used, feeding from the outer circle. After the cutting is completed, the end face is then turned, and the processing is carried out sequentially. Even for numerically controlled lathes, this is the case, resulting in low efficiency in the production of a large number of such parts. Summary of the Invention

[0003] In view of the deficiencies of the prior art, the present invention provides a one-piece machine tool for turning the end face of a metal pipe and simultaneously cutting the inner and outer circles, solving the problem of low processing efficiency due to the need for sequential cutting and machining.

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: A one-piece machine tool for turning the end face of a metal pipe and simultaneously cutting the inner and outer circles, including a bed body. A headstock is provided on one side of the bed body. A chuck is provided on the headstock, and a workpiece is clamped on the chuck. A Z-axis slide is provided on the bed body and can slide along the length direction of the bed body. A cutting structure is provided on one side above the Z-axis slide, and a turning structure is provided on the other side. A blanking structure is provided on the side of the Z-axis slide facing away from the workpiece.

[0005] Preferably, the cutting structure includes a first slide rail provided on the upper wall of the Z-axis slide. An outer circle slide and an inner circle slide are respectively slidably installed on the first slide rail. An outer circle tool holder and an inner circle tool holder are respectively installed on the outer circle slide and the inner circle slide. A servo motor is fixedly installed on one side of the first slide rail, and a pair of pull screws is installed at the driving end of the servo motor. The outer circle slide and the inner circle slide are respectively screwed on both sides of the pair of pull screws.

[0006] Preferably, the turning structure includes a second slide rail provided on the upper wall of the Z-axis slide. A turning slide is slidably installed on the second slide rail. A face tool holder is installed on the turning slide. An electric push rod is fixedly installed on one side of the second slide rail, and the telescopic end of the electric push rod is fixedly connected to the turning slide.

[0007] Preferably, the blanking structure includes a column fixedly installed on the Z-axis slide. A sliding sleeve is slidably sleeved on the column. A blanking frame is fixedly installed on the side of the sliding sleeve close to the workpiece.

[0008] Preferably, the sliding sleeve is a circular ring structure with an opening on one side. Ear plates are integrally formed at both ends of the opening of the sliding sleeve. A bolt is inserted between a pair of ear plates, and a nut is screwed at the end of the bolt.

[0009] Beneficial Effects

[0010] The present invention discloses an integrated machine tool for metal pipe end face turning and simultaneous inner and outer circle cutting, which has the following beneficial effects: the special machine tool is provided with an outer circle cutting tool holder, an inner hole cutting tool holder and an end face tool holder. During operation, the three tool holders are simultaneously in motion for turning, which is three times the efficiency of traditional machine tools. In addition, two knives are used for turning during cutting, which disperses the heat concentration point, reduces thermal deformation, and improves precision. The machine tool is suitable for the production of large quantities of such parts. A material unloading rack is also provided. When the finished product is unloaded, it does not need to be manually received, and it falls into the rack by gravity, which has high safety. BRIEF DESCRIPTION OF THE DRAWINGS
