The utility model discloses a portable multifunctional
machine tool fault detection device, and relates to the technical field of
machine tool maintenance. The device comprises a mounting plate, a detection
assembly is arranged on the upper surface of the mounting plate, and a grip
assembly is further arranged on the lower surface of the mounting plate; the detection
assembly comprises a detection shell fixedly connected to the upper surface of the mounting plate. According to the utility model, the
odor sensor and the visual camera in the detection shell are used for carrying out fault detection on the
machine tool in various
modes, and the driving rack drives the gas collecting hood to rotate in a reciprocating manner, so that air on the
machine tool is guided into the detection shell through the gas collecting hood for detection; the problems that in the prior art, the function is single, and fault detection cannot be conveniently conducted on the interior of the
machine tool are solved, meanwhile, the mounting plate and the detection structure are conveniently held through the holding rod, the position and angle of the detection structure are adjusted through the second lead screw, the second U-shaped frame and the third U-shaped frame, and the problem that in the prior art, carrying is not convenient is solved.
