Description

Alloy cutter assembly and cutter clamp Technical Field The invention relates to the technical field of alloy boring cutters, in particular to an alloy cutter assembly and a cutter clamp. Background Boring tools are boring tools that are dedicated to hole machining, typically with one to two cutting edges, and can be used to roughen, semi-finish, or finish an existing hole. It is suitable for various numerical control machining equipment, such as lathes, boring machines and milling machines. When the fine boring cutter is regulated, the operation flow must be strictly followed, namely, firstly unscrewing the locking bolt, and then rotating the regulating knob to carry out fine adjustment. If the adjusting knob is directly rotated, abnormal abrasion is generated due to the fact that the locking force is not released by the matched threads between the threaded rod and the movable shaft, and the gap is increased and the adjusting precision is obviously reduced due to the fact that the abnormal abrasion is caused for a long time. Because the process is complicated, the locking bolt is easy to neglect in actual operation, and many users can adjust the locking bolt without processing the locking bolt, so that the abrasion of parts is accelerated, the positioning stability is affected, and the service life of the fine boring cutter is finally shortened. And in the current common construction, the tool holder is usually fastened directly to the movable shaft by means of bolts only. The connecting mode has hidden trouble in the use process, when the machine tool continuously vibrates or is impacted by cutting force, the bolt can be gradually loosened, and relative displacement or complete separation is generated between the cutter clamp and the movable shaft. Once the alloy boring cutter deviates in processing, the cutting edge deviates from a preset track, unexpected cutting or scratching is easily formed on the inner wall of the work, the damage is difficult to repair, the workpiece is scrapped directly, and the processing cost and the quality risk are increased. In view of this, we propose an alloy cutter assembly and cutter holder.
