Description

Technical Field

[0001] The utility model relates to the technical field of motor end cover processing, in particular to a motor end cover hole enlarging device. Background Art

[0002] Motor end caps are the covers of the motor housing, generally divided into front and rear caps, used to secure and support the motor shaft. Hole reaming is a forging process that enlarges the bottom of a drilled hole or the bottom of certain foundation piers to increase the load-bearing area. This process reduces the wall thickness of the hollow blank and increases its inner and outer diameters. It is used to increase the inner diameter of workpieces with holes, such as pipes, cups, or housings.

[0003] Prior art publication number CN210702013U discloses a motor end cover reaming device, which belongs to the field of reaming processing technology, including a frame, a base and a fixed frame. The top surface of the frame is fixedly connected to the base, and the fixed frame is installed on one side of the base. A blanking hole is opened on the top surface of the base, and anti-slip pads are bonded on both sides of the top surface of the base. The top surface of the inner cavity of the fixed frame is fixedly connected to a reinforcement plate, the bottom surface of the reinforcement plate is fixedly connected to a hydraulic telescopic rod, and the bottom surface of the hydraulic telescopic rod is fixedly connected to a mounting plate.

[0004] The reaming column in the above device is fixed at the center of the bottom of the three-jaw chuck.

At the same time, the position of the reaming column is not adjustable. When the diameter of the hole to be expanded is different, the reaming column of different diameters needs to be replaced, which is inconvenient to use. Utility Model Content
