Abstract
This invention uses disc shaped cams in enlarged hoes in machine feet to allow a machine to be moved and properly installed to the bedplate. Once the machine is in the proper location, the cams are locked into place with a set screw which prevents the cams from rotating and the machine from moving. The machine foot is then secured to the base by a washer and the manufacturer's specified anchor bolt is torqued to the proper value.
Claims15
A method for installing a machine, the machine comprising:
- at least one machine foot, each machine foot having a machine foot opening;
- the method comprising:
- setting the machine on a bedplate;
- moving the machine on the bedplate so that the machine is properly aligned, the machine foot openings being positioned over bedplate bolt holes;
- for each machine foot opening:
- setting an outer cam in the machine foot opening, the outer cam having an outer cam opening offset from the center of the outer cam;
- screwing a locating stud through the machine foot opening and the outer cam opening into the bedplate bolt hole;
- rotating the outer cam to maximize the distance between the locating stud and the edge of the outer cam opening;
- placing an inner cam on the outer cam, the inner cam being formed to fit within the outer cam opening, the inner cam having an inner cam opening offset from the center of the inner cam, the bottom of the outer edge of the inner cam being chamfered;
- rotating the outer cam and the inner cam until they engage;
- placing downward pressure on the inner cam to insert into the outer cam opening;
- on the side of the machine foot, screwing a set screw into a set screw hole to press the outer edge of the outer cam;
- removing the locating stud from the bolt hole;
- placing a washer over the outer cam and the inner cam, the washer having a diameter greater than the diameter of the outer cam;
- and
- bolting the washer and the machine foot to the bedplate through the inner cam opening into the bedplate bolt hole.
An assembly for bolting a machine to an equipment foundation having at least one bedplate thereon, the machine having at least one machine foot, each machine foot having:
- a machine foot bolthole, and
- a set screw hole extending between a lateral edge of the machine foot and the machine foot bolthole,
- wherein each machine foot is positioned over and contacts one of the at least one bedplates;
- the assembly comprising:
- an outer cam having an outer cam opening offset from the center of the outer cam, the outer cam configured to fit within the machine foot bolthole;
- an inner cam fit within the outer cam opening, the inner cam having an inner cam opening offset from the center of the inner cam, the bottom of the outer edge of the inner cam being chamfered, and the bottom of the inner edge of the inner cam being chamfered;
- a set screw configured to extend through the set screw hole to contact the outer edge of the outer cam, thereby pressing the outer cam against the inner cam;
- a washer having a diameter greater than the diameter of the outer cam, the top of the inner edge of the washer being chamfered, the bottom of the inner edge of the washer being chamfered, the washer being positioned over the top side of the outer cam and the top side of the inner cam and configured to contact the top side of the machine foot;
- and
- an anchor bolt extending through an opening in the washer and the inner cam opening inner cam, and configured to be fastened to the bedplate to secure the machine foot to the bedplate.
