Description

Technical Field

[0001] The utility model belongs to the technical field of chamfering devices, in particular to an aluminum bushing end face chamfering machine. Background Art

[0002] Bushings are accessories used outside mechanical parts to achieve sealing, wear protection and other functions. They refer to rings that act as gaskets. In the field of valve applications, bushings are inside the valve cover and are generally made of corrosion-resistant materials such as polytetrafluoroethylene or graphite for sealing. Bushings can also be used as gaskets in other fields.

[0003] For example, an automatic chamfering machine disclosed in patent number CN209424682U includes a frame, the frame is provided with a workbench for placing the end cover, a liftable tool holder and a controller, the tool holder is provided with a chamfering knife and a driving motor for driving the chamfering knife to rotate, and the tool holder is provided with a detection component, and the detection component is used to detect the position of the planetary hole on the end cover. An automatic chamfering machine of the utility model can determine the position of a planetary hole on the front cover to be chamfered by setting a detection component, and then confirm the position of the center hole of the front cover by conventional point measurement. Thus, the workpiece coordinate system can be accurately constructed, and there is no need to set a locating pin on the fixture that fixes the front cover, and there is no need to divide the chamfering process into two steps, which shortens the process route and reduces the cost; at the same time, because the chamfering is completed by CNC machining, the chamfer size is uniform.

[0004] In the current existing technology, bushings are divided into a variety of materials, including aluminum bushings. When the aluminum bushing is in use, the bottom end face needs to be chamfered in order to better play the role of a cushion. Due to the special shape of the bushing, when the chamfering machine is used for chamfering, a lot of waste chips will remain on the chamfering machine. These waste chips cannot be cleaned during the chamfering process and can only be cleaned after the operation is completed. During the chamfering process, the waste chips accumulated around the aluminum bushing will affect the processing accuracy, thereby affecting the final quality.

[0005] Therefore, in view of the above problems, an aluminum bushing end face chamfering machine is proposed. Utility Model Content

When the aluminum bushing is used, the bottom end face needs to be chamfered to better play the role of a cushion. Due to the special shape of the bushing, when the chamfering machine is used for chamfering, the chamfering A lot of waste chips will remain on the chamfering machine. These waste chips cannot be cleaned during the chamfering process and can only be cleaned after the operation is completed.
