Description

Technical Field

[0001] The utility model relates to the technical field of drilling devices, in particular to a bell-shaped shell drilling device. Background Art

[0002] The bell housing drilling device is a processing device specially used for the bell housing of the ball cage constant velocity universal joint, which is mainly used to accurately drill holes on the bell housing. This device is usually equipped with a positioning fixture and a high-precision drilling power head to ensure that the position, size and shape of the hole meet the design requirements.

[0003] According to the search, the Chinese patent document, announcement number: CN214185316U, discloses that the utility model discloses a bell-shaped shell drilling device for an inner ball cage universal joint, which belongs to the technical field of universal joints, including a bottom plate, a support plate fixedly connected to the left side of the upper part of the bottom plate, a top plate fixedly connected to the upper part of the support plate, a lifting rod installed below the top plate, a mounting seat fixedly connected to the lower part of the lifting rod, a first motor fixedly connected to the right side of the upper part of the mounting seat, a first pulley fixedly connected to the right side of the first motor, a screw rod rotatably connected in the middle of the mounting seat, a second pulley fixedly connected to the right side of the screw rod, a moving seat threadedly connected in the middle of the screw rod, a collection box above the bottom plate, a base fixedly connected above the collection box, a baffle installed outside the base, and the inside of the baffle is hollow. In the utility model, by setting the baffle, it is possible to avoid iron filings splashing and injuring people during the drilling process, and the fan ventilates the inside of the baffle, so that the iron filings generated during the drilling process can be blown into the collection box, which is convenient for subsequent cleaning.

[0004] When the drilling device is designed to adjust the drill bit position, the drill bit can only be adjusted through one threaded shaft, resulting in the drill bit being able to move only along one axis during adjustment. When precise holes need to be opened in multiple positions on the bell shell, single-axis adjustment may not meet the requirements. In view of this, we provide a bell shell drilling device.
