Description

Technical Field

[0001] The utility model relates to the field of drilling, in particular to a graduated drilling device. Background Art

[0002] Large valves are mainly composed of valve body, valve stem, valve disc (valve core), drive device and worm gear box. The worm gear box is a mechanical device that uses the cooperation of worm wheel and worm to reduce speed and increase torque, and indexing drilling is mainly used for drilling the bottom hole of worm wheel thread in worm gear box.

[0003] Indexed drilling is a more sophisticated drilling technology, often used in applications that require precise hole distribution, such as gear processing, precision mechanical parts, etc. In indexed drilling, in addition to drilling holes, it is also necessary to accurately measure and locate between holes to ensure that the position of each hole is arranged according to a specific spacing to achieve high-precision hole distribution.

[0004] For example, Chinese patent CN217096921U discloses a drilling indexing device. By setting a camshaft, a cam handle, a lifting sleeve and a lifting platform, the cam handle can rotate 90 degrees forward and backward. When it is rotated to the lifting slot position, the lifting platform and the lifting sleeve are in the lowest position, realizing the workpiece release function and the workpiece clamping and fixing.
