Description

Technical Field

[0001] This utility model relates to the technical field of diesel engine manufacturing, and in particular to a diesel engine fan bracket chamfering machine. Background Technology

[0002] Diesel engine fan brackets (usually made of cast iron or cast steel) have sharp edges after casting, which need to be chamfered to avoid scratches during assembly and to improve fatigue strength.

[0003] Existing chamfering machines, such as the aluminum alloy plate chamfering processing device disclosed in utility model patent application number 202321062151.0, mainly include a frame. A fixed bracket and an adjusting bracket are respectively installed on both sides of the upper surface of the frame. A fixed block is installed on the fixed bracket, and a movable block is installed on the adjusting bracket. The fixed block has a first inclined surface, and the movable block has a second inclined surface. The first and second inclined surfaces are arranged opposite each other, forming a V-groove. A chamfering groove is provided at the bottom of the V-groove. In use, during chamfering, the right-angle position of the aluminum alloy plate is placed on the V-groove, so that the acute angle of the aluminum alloy plate passes through the chamfering groove. The processing device then performs chamfering processing on the acute angle.

[0004] However, most existing chamfering machines require changing the chamfering blade to adjust the chamfering angle, which is very troublesome as it needs to be disassembled and reassembled each time. Moreover, the brackets are of different shapes, which result in poor fixation and affect the chamfering effect. Utility Model Content
