Description

Technical Field

[0001] The utility model relates to a metal block chamfering device, in particular to a metal block multi-angle chamfering device, belonging to the technical field of chamfering. Background Art

[0002] Chamfering refers to the process of cutting the edges and corners of a workpiece into a certain slope. Chamfering is to remove burrs on parts caused by machining and to facilitate part assembly. Generally, chamfers are made on the ends of parts. However, chamfers specifically pointed out in the drawings are generally requirements of the installation process, such as the installation guide of bearings. Some arc chamfers can also reduce stress concentration and strengthen the strength of shaft parts.

[0003] The utility model with patent number CN217166720U discloses a metal block chamfering jig, including a workbench, a mobile table, a U-shaped slider, a fastening bolt, a support frame, a cutting machine and a T-shaped round rod. The left end of the workbench is equipped with a mobile table for sliding up and down, and the top of the mobile table is equipped with a U-shaped slider for sliding forward and backward, and the left end of the U-shaped slider is equipped with a fastening bolt. The utility model fixes the position of the cutting machine by moving the first and second magnetic blocks to adsorb and fit the T-shaped round rod and the magnetic strip respectively, and can also fix the position of the rotating rod by adjusting the bolts and the circular rod, and can accurately adjust the rotation angle of the cutting machine by the pointer and the angle ruler.

[0004] When processing metal parts, the metal blocks will be chamfered. Although the device in the above patent can chamfer metal blocks of various specifications, it can only chamfer one position. If chamfering operations are required at multiple positions, it needs to be disassembled and then re-clamped, which reduces the chamfering efficiency. For this reason, we provide a multi-angle chamfering device for metal blocks to solve the above problems. Utility Model Content
