The boring machine is accurate and easy to position

The machine bed has strong rigidity, good precision retention, a wide range of spindle speed, and the feed system is driven by an AC servo motor, which can meet the needs of various deep hole processing processes. The oiler is tightened and the workpiece is tightened by a hydraulic device, and the instrument display is safe and reliable.
The boring machine is also used to bore the cylinder holes and cylinder liner inner holes of internal combustion engines such as automobiles and tractors, and can also be used for precision boring of the inner holes of other mechanical parts.
The positioning device of the boring machine is characterized by: comprising a positioning seat, a positioning top core and at least three identical positioning columns, the positioning seat includes a support seat and a positioning sleeve, and the side wall of the positioning sleeve is provided with at least three through holes that cooperate with the positioning columns, each through hole is perpendicular to the center line of the positioning sleeve, and the positioning top core is in the shape of a nail, and its fixed end is provided with a nail cap, and its working end is a cone, and the cone is against the inner end of each positioning column. The beneficial effects of the new technology compared with the prior art are that the positioning device of the cylinder boring machine has a simple structure, is easy to use, has accurate positioning, is low in cost, is easy to implement, and greatly improves production efficiency.
