Problems solved by technology
[0002] At present, the domestic crankshaft production line drills the center hole and the outer circle of the car mainly through two special machines for drilling the center hole and the outer circle of the car, and there are a large number of simple special machine tools for drilling the center hole that are not consistent in the size of the center hole. Well, the quality of the batch cannot be guaranteed; if a special machine for drilling center holes that can guarantee the quality is used, there will be problems such as high cost, large volume, and difficulty in product changeover, and it is also not suitable for mass production.
[0003] If, on the basis of the center hole drilling machine tool, a separate special machine tool for lathing and outer circle is added, it is necessary to increase the process separately, occupying equipment, personnel and space

The invention discloses a machine tool for center hole drilling and external circle sleeving and turning. The machine tool comprises a base. Sliding rails are arranged on the base. A fixed turning boxis mounted at one ends of the sliding rails. A fixed cushion layer is arranged on the lower portion of the fixed turning box. A turning tool disc is arranged on the side face of the fixed turning box, and a center drilling tool is arranged in the middle of the turning tool disc. A clamp table and a moving drilling machine are arranged on the sliding rails, and the clamp table is located between the fixed turning box and the moving drilling machine. The machine tool can complete the functions of center hole drilling and external circle sleeving and turning at the same time and has the advantages of being good in universality, low in manufacturing cost and compact in structure, improving production efficiency and the like.
