A spraying tooling of a motor vehicle wheel hub is provided. The spraying tooling includes an assembly line, multiple wheel hub bases each capable of moving on the assembly line, multiple driving mechanisms each capable of driving a wheel hub base to rotate at a preset position on the assembly line, multiple triggering components each capable of triggering a driving mechanism to operate, multiple maintaining components each capable of maintaining a preset time for a triggering component, and a control component; the wheel hub base includes a sliding seat capable of moving on the assembly line and a tray capable of rotating along with rotation of the driving mechanism, and the tray is rotatably mounted on the sliding seat; and all of the driving mechanisms and the triggering components are electrically connected to the control component.

A versatile transport rack uses a rectangular shaped horizontal frame and one or more vertical frames that extend upwardly therefrom. Hinge pin receiver pairs are attached to the vertical frame and receive door pin pairs of a vehicle door. Either castors or axle-based wheel sets are removably attached to the horizontal frame in order to move the device about. Plates having appropriately placed templates are attached to the horizontal frame and/or the hinge pin receivers to hold various implements.

A rack system for retaining and maneuvering items to be spray-coated, including car members configured to support the items to be spray-coated, multiple attachment devices configured to mate with the one or more car members and attach to the items to be spray-coated, a horizontal rail configured to support the one or more car members and to provide a channel for the one or more car members to move along a length of the horizontal rail.

The present invention discloses a two-dimensional code protective paint spraying equipment for a wheel hub, including a centering device, a paint spraying device, and a review device, which covers a paint film with a certain hardness and transparency on a QR code of a hub, effectively avoiding damage to the QR code by the hub during the loading process, ensuring full flow traceability of the hub.

A versatile transport rack uses a pair of end frames that are each pivotally attached to a connector frame on opposing sides thereof thereby forming an article support device. Each frame has casters removably attached thereto. One or more vertical frames and/or one or more relatively flat base plates are removably attached to an upper surface of the versatile transport rack. Hinge pin receiver pairs are attached to the vertical frame and receive door pin pairs of a vehicle door.

A system and method include a frame member and an applicator. The frame member includes a hollow frame and a distribution component arranged in the interior of the frame. The distribution component includes a base component and a conduit on its exterior surface. The applicator delivers a fluid, which can include an anti-corrosion material, to the distribution component, which fluid is then delivered by the conduit throughout the interior of the frame and ejected through discharge openings of the conduit onto the interior surface of the frame to coat the frame with the fluid. The fluid may form an anti-corrosion coating on the interior surface of the frame.

A system for retaining and maneuvering workpiece items to be spray-coated, the system including a workpiece hanger mount including a body portion, two side portions extending downward from the body portion to form an upper open space therebetween, two flange portions extending inwardly respectively from proximate distal ends of the two side portions to form a lower open space therebetween, and a groove formed in an upper surface of each of the flange portions, and one or more workpiece hangers including a lower portion configured to be attached to a workpiece, and an upper portion having two side tabs extending away from one another and configured to be selectively received in the respective grooves formed in the flange portions of the hanger mount, wherein a workpiece is hung from the system by attaching the workpiece to one of the workpiece hangers and mounting the workpiece hanger in the hanger mount.

The present invention is a support system made of collapsible stands to hold moulding and trim for the purpose of painting and drying. The stands fold flat for easy storage, setup quickly, and allow the painter to easily paint many pieces of trim on a relatively small footprint compared to what most painters currently usebuckets and 24's or sawhorses.

A mold paint-spraying device includes a frame and a mold fixed to the frame. A motor is fixed to the frame, an output end of the motor is fixedly connected to a mounting rack, a servo motor and a linear guide rail are fixedly connected to the mounting rack, a rail slide is arranged on the linear guide rail, a screw nut is fixed on the rail slide, a spray gun is fixed on the screw nut, and an output end of the servo motor is connected with a screw matching the screw nut.
