Description

Technical Field

[0001] The utility model relates to the technical field of automobile gearbox processing, in particular to a shell cutting device for automobile gearbox processing. Background Art

[0002] Automobile gearbox housings are generally molded or stamped. Both of these methods will leave excess waste on the edges, also known as flash material, which needs to be sheared and removed later to obtain a finished product that meets quality requirements.

[0003] The automobile gearbox casing is not heavy and has an irregular shape. Usually, the worker holds the casing and cuts off the waste material on the edge with a grinding wheel cutter. This cutting method will cause the cut waste material to splash to one side due to the centrifugal force caused by the rotation of the grinding wheel cutter, and the operator close to the cutter is easily injured.

[0004] Therefore, in order to address the situation in which the flying waste generated during the cutting of the above-mentioned automobile gearbox casing can easily cause injury to the operator, a cutting device with a protective structure can be designed. The design is based on the appearance of the automobile gearbox casing, and the protective structure is set in the direction where the waste may fly. Utility Model Content

The debris generated by the cutting is thrown to both sides due to the centrifugal force and splashes onto the protective mechanism, slides down along the protective mechanism and enters the chute for collection to prevent the debris from splashing and injuring people. During the cutting process, the bracket assembly serves as a temporary supporting structure for the casing of the automobile gearbox and can be temporarily placed to free the operator's hands and facilitate the corresponding operation of the cutting machine. During the cutting process, the auxiliary light always illuminates the cutting area in a dim environment.
