Description

Bidirectional adjustable cutter holder type milling cutter Technical Field The utility model relates to the technical field of milling cutters, in particular to a bidirectional adjustable cutter holder type milling cutter. Background Milling tools are rotary tools for milling machining having one or more cutter teeth. When in operation, each cutter tooth cuts off the allowance of the workpiece intermittently in sequence. Milling cutters are mainly used for machining planes, steps, grooves, forming surfaces, cutting workpieces, etc. on milling machines. The seat type milling cutter is one of milling cutters, and an insert is fixed to the seat by a holder. The cutter holder in the prior art is fixed in position of the milling cutter holder, the position of the cutter cannot be finely adjusted according to the use requirement, and the cutter holder can be adjusted only by replacing the cutter holder, so that the cutter holder is quite inconvenient. In view of the foregoing, there is a need for a bi-directional adjustable seat milling cutter to solve the above-mentioned problems. Disclosure of Invention In order to help solve the problems in the prior art, the bidirectional adjustable cutter holder type milling cutter adopts the following technical scheme that the bidirectional adjustable cutter holder type milling cutter comprises a cutter holder, wherein a plurality of cutter holder grooves are formed in the annular side of the cutter holder, cutter holders are arranged in the cutter holder grooves, and an insert is arranged on one side, far away from the cutter holder, of the cutter holder; The inner side of the tool holder is provided with an adjusting cushion block and a first adjusting screw, the contact surface between one side of the adjusting cushion block far away from the tool holder and the tool holder is an inclined surface inclined to the axial direction of the tool holder, and the first adjusting screw rotates to enable the adjusting cushion block to move along the axial direction of the tool holder.
