Description

Technical Field

[0001] The utility model relates to the technical field of reaming, in particular to a three-hole group reamer. Background Art

[0002] Reaming is a method of removing a small amount of metal layer from the hole wall of a workpiece with a reamer to improve its dimensional accuracy and the surface quality of the hole. Reaming is one of the finishing methods for holes and is widely used in production. For smaller holes, compared with internal circle grinding and precision boring, reaming is a more economical and practical processing method. Reaming is a method of removing a small amount of metal layer from the hole wall of a workpiece with a reamer to improve its dimensional accuracy and the surface quality of the hole.

[0003] Currently, in order to provide the smoothness and dimensional accuracy of the inner wall of the holes on a workpiece, a reamer needs to be used for reaming. However, when reaming the holes on a circular workpiece, it often requires workers to ream one by one, with low work efficiency, inconvenient for reaming three holes simultaneously, and due to different hole pitches, the existing lower positions are inconvenient for synchronous adjustment, having the disadvantage of poor applicability.

When in use, during the process of reaming a workpiece with three holes circumferentially and equally spaced, the staff first centrally installs the workpiece below the group reamer device, and makes the holes on the workpiece and the reamer on the same axis. Then, the staff adjusts the positions of the three reamers according to the parameters of the three holes on the workpiece. During the adjustment process, the staff controls the servo motor to work through the controller. The servo motor drives the rotating shaft to rotate. While the rotating shaft rotates, it drives the driving bevel gear to rotate together. Then, the driving bevel gear drives the three driven bevel gears meshed with it. Furthermore, the driven bevel gears drive the corresponding lead screws to rotate. When the lead screws rotate, the sliders threadedly connected to their surfaces slide in the chutes, so that the three driving motors, tool holders and reamers move inwards or outwards synchronously. According to the parameters, the distance between the three reamers is adjusted to align the reamers with the holes on the workpiece fixed below. Then, the next reaming work is carried out. The group reamer device can be applied to ream workpieces with different three holes circumferentially and equally spaced by adjusting the positions of the three reamers, and the three holes are reamed simultaneously, achieving the purpose of improving work efficiency and applicability.
