renewable milling cutter

Abstract

The invention discloses a renewable milling cutter, which comprises a coaxial cutter head, a connecting rod and a cutter handle. The cutter head and the connecting rod are fixed, and the connecting rod axially runs through the cutter handle. A plurality of clamping strips are disposed on the outer peripheral surface of the connecting rod along a circumferential direction, the clamping strips extend to two end surfaces of the connecting rod axially along the connecting rod, and the end surfaces of the clamping strips are in a T shape. Clamping grooves matching the clamping strips are arranged on the inner peripheral surface of the cutter handle along its circumferential direction, and the clamping grooves extend to two end surfaces of the cutter handle axially. A cutter handle end far from the cutter head is provided with a radial through hole, the inside of which is equipped with an internal screw thread. An external screw thread equipped locking bolt runs through the through hole to lock the connecting rod, and the internal screw thread cooperates with the external screw thread. When the locking bolt is loosened, the connecting rod can make axial movement, and the cutter head can be stretchable. After adjustment of the cutter head position, the locking bolt is used to lock the cutter head. Mutual cooperation of the clamping strips and the clamping grooves can effectively prevent circumferential displacement of the cutter head and the cutter handle.

Description

Technical field [0001] The invention relates to a regenerable milling cutter. Background technique [0002] The wear and tear of the milling cutter is a relatively large part of the production cost, and the milling cutter has to be replaced due to wear or breakage. Putting scrapped milling cutters back into use can effectively reduce production costs. However, the length of the milling cutter will be shortened during the grinding process, which will cause it to be incompatible with the milling machine, so it is difficult to truly reuse the milling cutter. Summary of the invention [0003] The purpose of the present invention is to provide a regenerable milling cutter, the cutter head can be telescopically mounted on the tool holder, the position of the cutter head can be adjusted along the axial direction, and the circumferential displacement of the cutter head and the tool holder can be effectively avoided. [0004] In order to achieve the above objective, the technical solution o...

[0002] The loss of the milling cutter is a relatively large part of the production cost, and the milling cutter has to be replaced due to wear or breakage

Grinding scrapped milling cutters and putting them back into use can effectively reduce production costs, but the length of milling cutters will be shortened during the grinding process, resulting in a mismatch with the milling machine, so it is difficult to truly realize the reuse of milling cutters
