    Abstract: The present invention discloses a method for checking the design of locking assemblies, comprising: calculating a pressure on each contact surface and a torque that can be transferred by a spindle and a bushing after locking assemblies are locked, and comparing the calculated torque with the designed maximum transferable torque to calculate a torque safety coefficient; with a minimum fit clearance, calculating a resultant stress of components, and comparing the resultant stress with a yield strength of the material of the components to calculate a strength safety coefficient of the components; and obtaining a pre-tightening force of the bolts according to a given pre-tightening moment of the bolts, calculating a maximum equivalent stress of the bolts, and obtaining a safety coefficient of the bolts. This method in the present invention can effectively verify the rationality of design of locking assemblies, reduce the manufacture risk and increase the yield of products.

    Abstract: A casting-rolling side sealing device with an electromagnetic stirring function is provided and includes a pair of side sealing plates covering two side ends of a casting-rolling zone from a casting-rolling starting end to a casting-rolling ending end respectively, a pre-tightening force is formed between one of the side sealing plates and adjacent casting rolls. A pulse end of a first electromagnetic assembly releases first pulses along a first axis direction parallel to a direction from the side ends to a center of the casting-rolling zone. The first pulses are configured to generate an electromagnetic stirring effect in the casting-rolling zone. A second electromagnetic assembly is arranged on each of the side sealing plates, a pulse end of the second electromagnetic assembly releases second pulses along a second axis direction perpendicular to the first axis direction.

    Abstract: A robot includes a truss assembly, a walking assembly, a power unit, and a rack including a guide pillar, a second link. The truss assembly is disposed on the top of the rack. The walking assembly is disposed in the rack and fixedly connected to the rack through a bearing. The power unit is disposed on the rear end of the rack. An oil tank is provided with a hole. The truss assembly is configured to place the robot into the oil tank through the hole. The walking assembly is configured to drive the robot to move along the axis of the oil tank and to prevent the robot from toppling in the oil tank. The power unit is configured to clean the inside of the oil tank. The walking assembly includes two active walking assemblies, a drive assembly, and a folding assembly.

    Abstract: A special roller machine for a metal polar plate. A box body is a square with a circular through hole in the middle part. Upper and lower pressing rollers are mounted in the circular through hole; the upper and lower pressing rollers are mounted in grooves formed in the lower sides of upper and lower sector rotating bodies through bearing seats and are connected with upper and lower rotating blocks respectively; the rotating blocks are symmetrically arranged and are connected with upper and lower servo electric cylinders through connecting rod mechanisms respectively, then the pressing rollers are finely adjusted; four identical arch-shaped plates are mounted on the inner surface of the circular through hole for locating the rotating blocks; and main transmission is implemented in such a way that a servo motor drives the lower pressing roller to move through a safety coupling, a reduction gearbox and a cross coupling.
