Description

Technical Field

[0001] The utility model relates to the technical field of crankshaft processing, in particular to a sawing machine with a protection mechanism for crankshaft processing. Background Art

[0002] Sawing machines are mainly used to cut various objects or materials. Their working principle is to achieve cutting through the reciprocating motion of saw blades or saw belts. As an important mechanical part, the crankshaft has a more complicated processing process and requires the comprehensive application of multiple processing methods. During the crankshaft processing, if a component on the crankshaft needs to be cut or excess material needs to be removed, a sawing machine is often required.

[0003] Publication No. CN220006216U discloses a crankshaft processing sawing machine, comprising a sawing machine body and a dust removal assembly, the dust removal assembly comprising a wind hood, a shunt pipe, a dust removal box and an exhaust fan, the sawing machine body is used to cut and process the crankshaft, the dust removal assembly is used to absorb and filter out the iron chips generated by the crankshaft cutting, to prevent the iron chips from floating into the air and being inhaled by workers and causing lung diseases, specifically, when the sawing machine body cuts the crankshaft and generates iron chips, the exhaust fan is powered on to operate the shunt pipe to generate suction, so that the wind hood absorbs the iron chips generated by the cutting, and the iron chips are then introduced into the dust removal box through the shunt pipe for filtration, thereby preventing the iron chips from floating into the air and being inhaled by workers' lungs. This solves the problem that the dust removal effect of the existing crankshaft processing sawing machine is poor, and the iron chips float when cutting and processing the crankshaft, which endangers the health of workers. However, the patent still has the following problems during actual use:

[0004] During the cutting process of the sawing machine, a large amount of iron chips will be generated when the sawing machine cranks the shaft. The scattered iron chips will pollute the on-site working environment. The above-mentioned device absorbs the scattered iron chips through the dust extraction device, but most of the flying iron chips will fall into the fixed structure, which is not convenient for cleaning. At the same time, since some existing sawing machines cannot clearly observe the cutting depth from the front when cutting parts, in order to ensure safe observation and avoid injury from the saw belt, it is necessary to move close to the side of the saw belt. However, the structure of the wind hood in the above-mentioned device will hinder observation and be inconvenient to use.

[0005] A sawing machine for machining a crankshaft having a protection mechanism is proposed in order to solve the above-mentioned problems. Utility Model Content
