Description

Combined T-shaped cutter Technical Field The utility model relates to a T-shaped cutter, in particular to a combined T-shaped cutter, and belongs to the technical field of T-shaped cutters. Background A T-shaped tool is a cutting tool commonly used in milling. T-shaped cutters, also known as T-shaped milling cutters, semicircle milling cutters or key slot milling cutters, are cutters which are assembled on milling machines and used for milling T-shaped grooves and side grooves of workpieces. In addition to T-grooves, T-knives may also be used to machine side grooves that may be used for specific assembly needs, lubrication channels, or other functions. Because of the special shape and design, the T-shaped knife can finish the processing of a plurality of surfaces in one cutting process, thereby improving the processing efficiency. The T-shaped knife may be adapted for use in a variety of machining modes, such as milling, side milling, contour milling, etc., which makes it more flexible and convenient in machining complex shapes and contours. In the prior art, a combined T-shaped knife with a bulletin number 201922358935.8 comprises a knife handle, a fastening cap, a clamping ring, a butt joint screw hole, a first thread column, a clamping groove, a fixing column, a clamping block, a connecting hole, a cutting edge and a second thread column. The connecting hole is located the top of fixed column, cutting edge fixed connection is on the top of fixed column, the vertical fixed bottom center department that sets up at the cutting edge of second screw thread post. The both sides contained angle of fastening cap is 60 degrees, through specific angle, satisfy the angle requirement of T type sword, the diameter of snap ring is greater than the fixed column, and the diameter of snap ring is less than the butt joint screw, be convenient for pass the fixed column through the snap ring, the fixed column passes through the fixture block chucking and dock with first screw thread post in the draw-in groove, prevent the dislocation, and then realize accurate butt joint, the fixed column passes through fastening cap and screws up with first screw thread post soon to it is fixed through the snap ring extrusion fixture block, guarantee to fix the fixed column firm, the cutting edge screws up the locking through second screw thread post and connecting hole and is connected.
