Description

Technical Field

[0001] The present invention relates to the field of mechanical technology, and in particular to a rotating device compatible with crankshafts of multiple models. Background Art

[0002] With the diversity of engine models, crankshafts also have differences. The equipment is required to be compatible with the rotation of crankshafts of different models. Therefore, when the crankshaft is guaranteed to be coaxial, but the crankshaft axis is inconsistent with the center of gravity of the engine assembly, the prior art still lacks a manual rotating crankshaft mechanism with a variable center of gravity position that is compatible with multiple models. The common rotating crankshaft mechanism in the prior art is generally that the center of the crankshaft is basically the same as the center of gravity of the engine assembly, or it is a model, that is, there is only one crankshaft; the technical solution is generally to press the crankshaft end face and directly rotate it through a rotating shaft that is consistent with the crankshaft axis. The disadvantage of the prior art is that it is not compatible with the rotating crankshafts of multiple models, and in the case of automatically flipping the engine assembly, the position of the engine's center of gravity is different from the crankshaft position, so it cannot be rotated directly on the crankshaft axis.

[0003] The Chinese patent with publication number CN206435560U, a crankshaft rotation drive device, discloses a crankshaft rotation drive device, which relates to the field of engine crankshaft rotation cleaning, and in particular, a crankshaft rotation drive device. The patent includes a bracket, a left clamping rotation shaft device and a right clamping shaft device, and is characterized in that the left clamping rotation shaft device and the right clamping shaft device are relatively arranged on the left and right sides of the bracket, and the left clamping rotation shaft device includes a crankshaft rotation drive shaft fixed to the bracket through a first bearing seat, a left clamping top shaft installed at the right end of the crankshaft rotation drive shaft, a crankshaft rotation drive reducer connected to the left end of the crankshaft rotation drive shaft and installed on the slide, a linear slider arranged under the slide and a linear guide matched with the linear slider, a left rotation drive shaft feed cylinder located below the linear guide and fixed on the bracket, and the piston rod end of the left rotation drive shaft feed cylinder is connected to the left end of the slide. The device does not slip when the crankshaft rotates, has a simple structure, high reliability, and is easy to maintain.

[0004] However, the prior art still lacks a mechanism for changing the center of gravity position and rotating the crankshaft compatible with multiple models. Summary of the invention

[0005] To solve the above-mentioned technical problems, the present invention provides a rotating device with a variable center of gravity position compatible with multiple models, including: a first rotating shaft, a second rotating shaft, a stop pin, a first gear, a second gear, a rotating plate, a baffle, and a driving mechanism, wherein the first gear is sleeved on one end of the first rotating shaft, the first gear is hinged to the second gear, the rotating plate and the baffle are arranged on the left and right sides of the second gear, the second rotating shaft is L-shaped, the horizontal axis of the second rotating shaft is sleeved outside the first rotating shaft, the first gear and the second gear are arranged in the vertical axis of the second rotating shaft, the stop pin is connected to the second rotating shaft, and the driving mechanism is connected to the second rotating shaft and drives the second rotating shaft to rotate.

[0006] The rotating plate positions the rotating crankshaft, the stopper pin positions the cylinder of the engine, and the first rotating shaft is manually rotated. The rotation of the first rotating shaft drives the first gear, the second gear, the rotating plate and the crankshaft to rotate in sequence; the driving mechanism drives the second rotating shaft to rotate, thereby driving the stopper pin and the cylinder of the engine to rotate. Through this design, when the center of gravity of the engine and the crankshaft are inconsistent, the rotation of the engine and the crankshaft can be achieved through one instrument.

[0007] Preferably, it also includes a spring, a connecting shaft, a fixed block and a fixed sleeve, one end of the connecting shaft is connected to the rotating plate and the baffle, the second gear sleeve is arranged on the connecting shaft, the fixed sleeve is arranged outside the connecting shaft, and a spring is provided in the gap between the fixed sleeve and the connecting shaft, and one end of the spring abuts against the fixed block.

[0008] Preferably, a hand wheel is further included, and the hand wheel is arranged at the other end of the first rotating shaft.

[0009] Preferably, the driving mechanism is a servo motor.

[0010] Preferably, it also includes a bearing sleeve, the bearing sleeve is sleeved on the second rotating shaft

[0011] The beneficial effect of the technical solution of the present invention compared to the prior art is that when the crankshaft axis and the center of gravity of the engine assembly are inconsistent, the rotating device provided by the present invention can be compatible with multiple models and realize stable rotation of the crankshaft and the engine.
