Abstract

The present invention belongs to the technical field of milling machines, and mainly relates to a novel cutter holder and base system for a milling machine. The cutter holder and base system according to the present invention aims to solve the problems in the prior art that a cutter holder structure is unreasonable, the cutting force of a cutter cannot be well dispersed in the cutter holder and a base, so that the service lives of the cutter holder and the base are shortened. The base is provided with a hole-shaped inner area and two curved surface areas, where the two curved surface areas are disposed in a circumferential area of the hole-shaped inner area, the curved surface areas are arranged at an angle, and each curved surface area includes two curved surfaces. The cutter holder improves its own usage performance while a lighter weight is achieved.

Abstract

A cutter holder and base system for a milling machine, comprising a cutter holder (1) and a base (2). A hole-shaped internal area (21), a curved surface area (22), and a curved surface area (23) provided on the base (2). The curved surface area (22) and curved surface area (23) are provided in the peripheral region of the hole-shaped internal area (21) and are arranged at a certain angle (E6); the curved surface area (22) comprises a curved surface (22.1) and a curved surface (22.2); and the curved surface area (23) comprises a curved surface (23.1) and a curved surface (23.2). The cutter holder (1) is fitted with the base (2) by means of curved surfaces, so that the stress can be dispersed during cutting of a cutter, thereby prolonging the service life of the cutter holder and base system.

Abstract

The present invention discloses a knife holder and base system for milling machine. The knife holder and base system comprises a knife holder provided with a fixed part and a base provided with an inner hole; and the fixed part penetrates the inner hole and is matched with a thread in the fixed part through a bolt to be used, so that the knife holder is fixedly connected with the base. According to the knife holder and base system for the milling machine, after the knife holder of the system structure is inserted in the base, more than two V-shaped faying surfaces and the V-shaped supporting surface serve as transition, the knife holder and the base are tensioned through the tensioning bolt, so that the knife holder and base system is of an integrated structure, and the cutting stress of a knife is transmitted into the base better through the knife holder.

Abstract

A blade holder base system for milling machines, comprising a blade holder (1) having a fixing part (101) and a base (2) having an inner hole (201). The fixing part (101) passes through the inner hole (201) and a fixed connection between the blade holder (1) and the base (2) is achieved by means of matching the bolt (3) and the thread in the fixing part (101). Each component can be conveniently replaced.
