AI Technical Summary

⚠Technical Problem

The existing cutting tool height adjustment has low precision, cannot be continuously adjusted, is cumbersome to operate, inefficient, lacks stability and rigidity, and is inconvenient to manage shims.

⚗Method used

It adopts a screw drive combined with a beveled wedge clamping structure. The screw and the fixed cylinder are connected by a thread to achieve precise height adjustment of the tool holder. Combined with an auxiliary spring to provide preload and a locking mechanism to ensure stability, it can achieve continuous stepless adjustment.

🎯Benefits of technology

Abstract

This utility model discloses an adjustable-height composite lathe tool, relating to the field of lathe tool technology. It solves the technical problems of existing solutions, such as low adjustment precision, inability to continuously adjust, cumbersome operation, and low efficiency. The tool includes a base, a tool holder, and a cutting blade. The cutting blade is disposed on the upper wall of the tool holder, which is slidably mounted on the base. A fixed cylinder is provided on the base, and a threaded hole is formed inside the fixed cylinder. A screw is rotatably mounted inside the tool holder, and the screw is threadedly connected to the threaded hole of the fixed cylinder. This utility model employs a screw-driven, inclined-plane-wedge-tightened structure. When the screw is rotated, its rotational motion is converted into linear micro-movement of the tool holder along the inclined plane through the threaded pair. The linear displacement of the tool holder is then converted into even smaller vertical displacement of the cutting blade through the inclined plane structure. This mechanical transmission method has a large transmission ratio, allowing the operator to easily achieve continuous, stepless, and high-precision adjustment of the cutting blade height by rotating the screw.
