Description

Technical Field

[0001] The utility model relates to a conveying device, in particular to a single-power synchronous centering and clamping conveying device. Background Art

[0002] Tube parts, especially long ones, tend to roll when being conveyed, and the contact area between the tube wall and the conveyor belt is very small, resulting in minimal friction. Therefore, the conveying process often requires complex mechanical support. Therefore, a conveying device that uses two conveyor belts to clamp the tube is a common method. However, most conveyor systems currently used in domestic tube production lines are overly complex, with the distance between the two conveyor belts fixed and unable to be adjusted. These systems can only transport tube parts with a single diameter, making them difficult to install and unable to accommodate the needs of multiple diameters. Utility Model Content

The driving motor and the meshing transmission gear group are installed on the frame, and the driving motor drives the first gear in the meshing transmission gear group to rotate, thereby driving the second gear in the meshing transmission gear group to rotate in the opposite direction, and the second gear is directly meshed with the first gear for transmission; the first gear and the second gear respectively drive a belt-type centering clamping assembly through a pulley transmission mechanism; the two belt-type centering clamping assemblies are arranged relatively parallel to each other to form a transmission space between the two; the brackets of the two belt-type centering clamping assemblies are arranged parallel to each other and are connected to a screw at the same time, and the two brackets are driven to move toward each other by two sections of screw teeth with opposite rotation directions on the screw.

[0005] The bracket is provided with a screw sleeve, which is connected to the screw rod; and the screw sleeves on the two brackets are driven by screw teeth with different rotation directions on the screw rod.

[0006] The belt-type centering clamping assembly comprises a driving wheel and a driven wheel, wherein the axles of the driving wheel and the driven wheel are both mounted on a bracket.

[0007] The driving wheel of the pulley transmission mechanism is driven by a driving wheel that is coaxially driven by a gear in the meshing transmission gear set through the pulley transmission mechanism.

[0008] The brackets of the two belt-type centering clamping assemblies are mounted on the guide column so as to be able to move relative to each other along the guide column.

[0009] The first gear and the second gear are of the same size to achieve synchronous transmission.

[0010] The transmission ratio of the driving wheel of the belt-type centering clamping assembly meshed with the first gear pair and the transmission ratio of the driving wheel of the belt-type centering clamping assembly meshed with the second gear pair are the same, so as to realize the synchronous driving of the two belt-type centering clamping assemblies.

[0011] Each pulley transmission mechanism is provided with a pressing idler wheel and a pressing slider.

[0012] The end of the screw is connected to the driving mechanism.

[0013] The driving mechanism is a hand wheel for driving the screw to rotate; or the driving mechanism is a motor driving a reducer.
