Equipment part laser cutting device and machining method

The invention provides an equipment part laser cutting device and a machining method.The equipment part laser cutting device comprises a cutting mechanism, a translation mechanism and a displacement mechanism for sliding arrangement of the front end, a bearing mechanism for containing equipment parts is further arranged below the displacement mechanism and placed on the ground, and the equipment part laser cutting device further comprises a bearing table placed on the ground; a bearing support is arranged in the middle of the top end of the bearing table, a base is arranged in the middle of the top end of the bearing support, and a linear sliding rail is arranged in the middle of the top end of the base. The laser cutting head can be better adjusted and controlled to ascend and descend on the basis of the machining stage of the part structure needing to be slidably fed and machined, then the part structure needing to be cut is rapidly cut and machined, and the specific position of the laser cutting head is ad
