The invention discloses a machine tool special for precise drilling of a tappet. The machine tool comprises a machine tool body, an oil pump arranged on the lower portion of the machine tool body anda control cabinet arranged at the upper end of the machine tool body. The machine tool is characterized in that the left end of the machine tool body is fixedly connected with a driving motor througha supporting frame, the right end of the machine tool body is fixedly connected with a material basket seat, and the upper portion of the machine tool body is provided with a rotary spindle in a penetrating mode through a bearing; the left end of the rotary spindle is connected with the driving motor through a belt, and the right end of the rotary spindle is fixedly connected with a hydraulic chuck plate; a material push plate is arranged in the chuck plate, and the right side of the chuck plate is provided with a drilling knife bed connected to the upper end of the machine tool body, and theupper end of the machine tool body is provided with a material receiving groove matched with the chuck plate. The machine tool special for precise drilling of the tappet has the beneficial effects that fixing and rotating of a workpiece are achieved, precise and efficient drilling of the workpiece is achieved through cooperation of the machine tool and the drilling knife bed, and the workpiece quality and the working efficiency are improved.
Description
technical field [0001] The invention relates to a processing machine tool, in particular to a special machine tool for tappet precise digging. Background technique [0002] The valve tappet is an important part of the engine gas distribution system. During the working process of the engine, whether its movement and rotation are flexible will affect the performance of the engine to a certain extent. [0003] The common valve lifters include straight cylinder type, mushroom type, waisted type or other special shapes, and each valve lifter has at least one oil guide hole and oil return hole. [0004] Among them, in the process of digging the inner hole of the straight-through type tappet, the pre-processing process is milling the spherical surface, and the post-processing process is drilling the oil hole. The current processing is rotary drilling, the shape of the drill is guaranteed by grinding the drill bit, and the shape of the drill bit determines the shape and roughness o...
