Abstract
A rotor disc brake lathe for simultaneously machining both left- and right-hand disc brake rotors of a vehicle wherein the rotors are mounted on opposite ends of a centrally supported horizontal drive shaft, and a pair of tool arm assemblies are mounted on both opposite end regions of a horizontal cross arm which is moved vertically on machine ways to effect selective engagement with and machining of the rotors. A spring biased vibration dampener is mounted on one of each pair of tool arms for engagement with one side of each rotor during the machining operation. A clutch mechanism to allow selective manual or motor driven vertical feed of the cross arm is provided.
Claims17
A disc brake lathe comprising:
- a machine base;
- a support stand on said base
- vertical guide means supported by said stand for providing a stationary planar way means;
- a cross arm assembly having guide surfaces interfacing with said way means and configured to enable aligned and confined movement of said cross arm assembly along said way means;
- at least one disc brake tool assembly secured to said cross arm assembly, and wherein said disc brake tool assembly comprises a pair of caliper arms, and a cutting tool being attached to each tool arm, and each said cutting tool being oriented to face an oppositely positioned cutting tool;
- a shaft rotatably supported by said machine base having means to rotably support at least one disc brake rotor at a selected position;
- drive means including an electrical motor rotating said shaft about its longitudinal axis;
- and
- an antichatter assembly supported by said tool assembly and positioned to engage a single side of the disk brake rotor comprising:
- a frame including a hollow tube-like housing mounted on said arm and extending toward a single side of the disc brake rotor when the rotor is supported on said shaft,
- a block contoured to engage and move along within said tube-like housing and having an end surface contoured planarly to engage a generally flat side region of a disc rotor mounted on said shaft, said block being positioned to engage at least a radially outer region of the rotor, and
- spring bias means on said tube-like housing for resiliently applying a bias force to said block and thereby applying a dampening force to said rotor;
- and
- feed means moving said tool assembly and antichatter assembly into engagement with said rotor.
