Problems solved by technology

Due to the surface-to-surface contact of this locking method, although locking at any angle can be achieved, the locking force is not enough and the control accuracy is difficult to guarantee. It is necessary to install an angle encoder on the final actuator for angle feedback, forming closed loop control system

Abstract

The invention discloses a mouse tooth disk locking mechanism for an efficient and compound milling disk mill device of a blisk. The mouse tooth disk locking mechanism is used for solving the technical problem that an existing hydraulic locking mechanism for the efficient and compound milling disk mill device of the blisk is poor in locking force. The technical scheme is that the mouse tooth disk locking mechanism comprises a disk mill box body (1), an inner box body (5), a worm (6), a worm gear (7), an outer box body (8), a serve motor (11), a left side fluted disk (2), a push ring (3) and a right side fluted disk (4). The left side fluted disk (2) and the right side fluted disk (4) are meshed, and two end faces of the push ring (3) are respectively matched with the left side fluted disk (2) and the right side fluted disk (4). The mouse tooth locking mechanism can generate locking force through mesh between tooth faces between mouse disk teeth so as to be large in locking torque and meet high-rigidity and large-torque requirements in a disk milling process. Furthermore, the minimum scale division of three piece type end face fluted disks of the mouse tooth disk is 1 degree so as to achieve accurate control of a swing angle of the disk mill device.

Description

technical field [0001] The invention relates to a Hirth disk locking mechanism, in particular to a Hirth disk locking mechanism of an integral blisk high-efficiency compound milling disk milling device. Background technique [0002] The locking mechanism of the well-known high-efficiency compound milling disc milling device for integral blisks adopts a hydraulic method. The hydraulic locking mechanism includes a brake ring, a brake seat, a gland and a sealing ring. When the brake is tightened, high-pressure hydraulic oil is introduced from the oil chamber to push the brake ring to deform, thereby generating friction, and using the braking torque provided by the friction force to achieve locking. Due to the contact between the surfaces of this locking method, although locking at any angle can be achieved, the locking force is not enough, and the control accuracy is difficult to guarantee. It is necessary to install an angle encoder on the final actuator for angle feedback to...
