The present invention provides an improved inner-supporting-type online roundness correcting device for a semifinished wheel, which comprises a machine frame, hydraulic cylinders, guide rails, servo motors and correcting wheels. When a bulge of the wheel is met, angles of left correcting wheels II are adjusted through a left servo motor, the left correcting wheels II are kept to be in contact with an inner rim of the wheel all the time and remain stationary in the position, and then, a left hydraulic cylinder enables a left correcting wheel Ito press the bulge of the wheel, so as to recover the roundness of the bulge; and when a depression of the wheel is met, right correcting wheels I are kept to be in contact with an outer rim of the wheel all the time and remain stationary in the position through a right hydraulic cylinder, the angle of a right correcting wheel II is adjusted through a right servo motor, and compressing hydraulic cylinders enable the right correcting wheel II to press the depression of the wheel, so as to recover the roundness of the depression.

The present invention relates to an online roundness correcting device for a semifinished wheel, which consists of a jacking and rotating system, a left correcting system, a right correcting system and a central locating system. According to the online roundness correcting device provided by the present invention, in service, an online roundness correcting function for the semifinished wheel can be achieved, and the corrected wheel has good roundness and cylindricity, so that not only can the labor intensity for workers be lowered, but also the online roundness correcting device has the characteristics of high degree of automation, advanced process, simple structure and safe and stable performance.

A wheel straightening apparatus including a rotatable attachment mechanism radially connected to a spindle that includes a locking cuff radially surrounding the spindle a sleeve coaxial to and rotatably connected to the locking cuff, an arm member having a first end and a second end opposed to the first end, a first face and a second face opposed to the first face, the first face of the elongated member connected to the sleeve at a location proximate to the first end and oriented parallel to the outer surface of the locking cuff, the arm member projecting perpendicularly outward from the locking cuff relative to the first edge of the locking cuff and a socket connected to the second face of the arm member at a location proximate to the second end of the arm member configured to removably receive a wheel working appliance.

A rub rail repair tool includes a tool engaging element disposed on one longitudinal side of a flange. A working element is disposed on the other longitudinal side of the flange. The working element is shaped to define a maximum diameter dimension and a minimum diameter dimension. The maximum diameter dimension is substantially equal to a distance between an undamaged rub rail affixed to a lateral edge of a truck bed frame. At least one tool engaging feature is formed in the tool engaging element. The tool engaging feature enables coupling of a torque arm to the tool engaging element to enable rotation thereof about a longitudinal axis thereof by applying force to the torque arm.

Aspects of the present invention relate to a repair insert (1-n) for repairing a box member (3). The box member (3) has a plurality of walls (11-1, 11-2, 13, 15) which form one or more cell (11-n). The repair insert (1-n) includes a first clamping member (21-1) for clamping against an interior of one of the walls (11-1, 11-2, 13, 15) of the box member (3); and a first engaging member (23-1) for engaging a first one of the walls (11-1, 11-2, 13, 15) of the box member (3). A first tensioning arm (27-1) is connected to the first clamping member (21-1). At least one first reactor arm (29-n, 31-n) is coupled to the first tensioning arm (27-1). The at least one first reactor arm (29-n, 31-n) is operative to apply a biasing force for biasing the first engaging member (23-1) towards the first wall (11-1, 11-2) when the first clamping member (21-1) is clamped to the box member (3). Aspects of the present invention also relate a vehicle (5) including a repair insert (1-n); and a method of repairing a box member (3).
