Description

Can be with dead compound main shaft of turnning and milling of pivot lock

Technical Field

The utility model belongs to the technical field of machining and specifically relates to a can be with dead compound main shaft of turnning and milling of pivot lock.

Background

The electric main shaft is a new technology which integrates a machine tool main shaft and a main shaft motor into a whole and appears in the field of numerical control machine tools, the electric main shaft comprises the electric main shaft and accessories thereof, a rotor of a motor is directly used as a main shaft of the machine tool, a shell of a main shaft unit is a motor base and is matched with other parts to realize the integration of the motor and the machine tool main shaft, and the electric main shaft, a linear motor technology and a high-speed cutter technology push high-speed processing to a new era.

In the application of a five-axis turning and milling composite machine tool, a turning tool needs to be installed under the condition that a rotating shaft stops rotating, at the moment, when the rotating shaft of a motor is required to stop rotating, the relative position of the rotating shaft needs to be fixed, and conventionally, a pin is installed on a tool shank, so that the tool shank and a shell are locked.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve the technical problem who exists among the background art, and provide a locking precision height, the bearing does not receive the dead compound main shaft of turnning and milling of pivot lock by force and rigidity are strong.

The technical solution of the utility model is that: the utility model relates to a can be with dead compound main shaft of turnning and milling of pivot lock, including the pivot, the piston cylinder is located the pivot outside, and its special character lies in: the main shaft further comprises a locking device which is a three-piece clutch tooth, the three-piece clutch tooth comprises a thrust fluted disc, a fixed outer fluted disc and a rotary inner fluted disc, the thrust fluted disc can be pushed by the piston cylinder, the fixed outer fluted disc and the rotary inner fluted disc can rotate along with the rotating shaft, the rotary inner fluted disc is arranged at the end part of the rotating shaft in a surrounding mode, the rotary inner fluted disc is arranged in the inner circle of the fixed outer fluted disc, the fixed outer fluted disc is fixedly connected with the inner side of the shell, and the thrust fluted disc corresponds to the fixed outer fluted disc and.

The utility model has the advantages of it is following:

the utility model discloses a three separation and reunion tooth structures install the fixed fluted disc of a slice on electric main shaft housing, and the rotatory fluted disc of installation a slice in the pivot is epaxial, and rear end locking piston cylinder installation a slice thrust fluted disc when needing to lock, promotes the thrust fluted disc through the piston cylinder, and rotatory fluted disc and fixed fluted disc mesh simultaneously, locks the fluted disc of casing and pivot simultaneously. Therefore the utility model discloses a mode locking pivot of three separation and reunion teeth, its precision is high, and the bearing is not atress and rigidity is strong.

Detailed Description

Referring to fig. 1, the utility model discloses a concrete embodiment structure includes pivot 1, piston cylinder 7, locking device, piston cylinder 7 is located the pivot 1 outside, locking device is three separation and reunion teeth 4, three separation and reunion teeth 4 are including the thrust fluted disc 6 that can be promoted by piston cylinder 7, fixed fluted disc 5 and can be along with the rotatory internal tooth dish 3 of pivot 1, rotatory internal tooth dish 3 encircles and sets up at pivot 1 tip, rotatory internal tooth dish 3 sets up in fixed fluted disc 5 is interior, fixed fluted disc 5 and the inboard fixed connection of casing 2, thrust fluted disc 6 corresponds fixed fluted disc 5 and the setting of rotatory internal tooth dish 3 on piston cylinder 7.

The utility model discloses the during operation, when pivot 1 stall, piston 8 through the piston cylinder 7 in promotes thrust fluted disc 6, makes the fluted disc on thrust fluted disc 6, rotatory inner fluted disc 3 and the fixed outer fluted disc 5 of three separation and reunion teeth 4 coincide completely, pins pivot 1 firmly, installs the lathe tool under the condition of pivot 1 stall, and then realizes lathe work, when needing pivot 1 to rotate, resets piston cylinder 7, and the fluted disc of three separation and reunion teeth 4 breaks away from can.

The above is only the specific embodiments of the present disclosure, but the scope of the present disclosure is not limited thereto, and the scope of the present disclosure should be subject to the protection scope of the claims.

Claims

1. The utility model provides a can be with dead compound main shaft of turnning and milling of pivot lock, includes the pivot, the piston cylinder is located the pivot outside, its characterized in that: the main shaft still includes locking device, locking device is three separation and reunion teeth, three separation and reunion teeth include thrust fluted disc, fixed outer fluted disc that can be promoted by the piston cylinder and can follow the rotatory interior fluted disc of pivot, rotatory interior fluted disc encircles and sets up at the pivot tip, rotatory interior fluted disc sets up in fixed outer fluted disc is interior, fixed outer fluted disc and the inboard fixed connection of casing, the thrust fluted disc corresponds fixed outer fluted disc and rotatory interior fluted disc setting on the piston cylinder.
