Abstract
A milling machine can include a frame; a milling assembly including a drum housing; and a connecting assembly for mounting the drum housing to the frame, the connecting assembly including: a mounting member on one of the frame or the drum housing; and a locking mechanism fixed to the other one of the frame or the drum housing, the locking mechanism including a rotatable angled-plane pin configured to connect to the mounting member.
Claims20
A milling machine comprising:
- a frame;
- a milling assembly including a drum housing;
- and
- a connecting assembly for mounting the drum housing to the frame, the connecting assembly including:
- a mounting member on one of the frame or the drum housing;
- and
- a locking mechanism fixed to the other one of the frame or the drum housing, the locking mechanism including a rotatable angled-plane pin configured to connect to the mounting member,
- wherein the angled-plane pin includes a head connected to a shaft and is rotatably fixed to a surface of the one of the frame or the drum housing, and
- wherein the rotatable angled-plane pin is rotated by an actuator located on the surface of the one of the frame or the drum housing and operatively coupled to the shaft to rotate the rotatable angled-plane pin.

A milling assembly comprising:
- a drum housing holding a rotatable milling chum;
- and
- a locking mechanism fixed to the drum housing for mounting the milling assembly to a frame of a milling machine, the locking mechanism including a rotatable angled-plane pin configured to connect to a corresponding mounting member on the frame,
- wherein the rotatable angled-plane pin includes a head connected to a circular shaft and is rotatably fixed to a top surface of the drum housing.
(canceled)
A method of connecting a milling assembly to a milling machine frame, the method comprising:
- positioning a locking mechanism fixed to one of a drum housing of a milling assembly or a frame of the milling machine proximate a mounting member on the other one of the frame or the drum housing, the locking mechanism including a rotatable angled-plane pin configured to connect to the mounting member;
- and
- rotating the rotatable angle-planed pin until it engages with the mounting member and clamps the drum housing to the frame,
- wherein said rotating the rotatable angled-plane pin is by an actuator located on a surface of the one of the frame or the drum housing and operatively coupled to a shaft to rotate the rotatable angled-plane pin,
- wherein the actuator includes a hydraulic piston fixed to the surface of the one of the frame or the drum housing and having a piston arm that is rotatably coupled to a connector fixed to the shaft.
