Description

Cutting cutter bar with replaceable blade Technical Field The utility model relates to the technical field of cutter bars, in particular to a cutting cutter bar with a replaceable blade. Background The cutting tool bar is a basic component for installing cutting blades in machining and is a core supporting structure of a tool system, and the cutting tool bar is mainly used for providing positioning reference and clamping force for the blades and transmitting power of a machine tool so as to realize cutting movement, and can be divided into a turning tool bar, a milling tool bar, a boring tool bar and the like according to machining types so as to adapt to blades (such as turning blades and milling blades) with different shapes. When the cutter bar is installed on the lathe cutter frame, the height of the cutter bar is usually adjusted through a gasket so as to ensure that the cutter point is equal to the center line of the main shaft. However, the size of the gasket is fixed, the adjustment accuracy is poor, the accuracy is limited by the thickness of the gasket, and the gasket is easy to wear or misplacement due to multiple times of adjustment. Disclosure of utility model The present utility model is directed to a cutting insert holder with replaceable inserts, which solves the above-mentioned problems. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The utility model provides a cutting cutter arbor of removable blade, includes handle of a knife and blade, the upper end of handle of a knife just is close to left edge department and is equipped with the standing groove, the blade is placed in the standing groove, the upper end of blade is equipped with first locking screw, the blade is fixed with the handle of a knife through first locking screw, the lower extreme of handle of a knife is equipped with the spout, sliding connection has a piece on the inside wall of spout, the spout is run through to the lower extreme of piece, the upper end of piece is inserted from a left side to the right side and is equipped with a plurality of vertical pillar that set up, be threaded connection between pillar and the piece, be equipped with the thing groove of putting of horizontal setting in the handle of a knife, the upper end of pillar runs through handle of a knife and fixedly connected with second gear, the second gear is located puts the thing inslot and is equipped with the bull stick of horizontal setting, fixedly cup joint has the first gear with that meshes with the second gear on the bull stick, the left end of bull stick rotates with the inside wall of putting the thing groove and is connected with knob throughout the handle of a knife.
