Drag chain self adaptive swing mechanism for monorail equipment

Abstract

The application provides a drag chain self-adaptive swing mechanism of a draping device, which can realize large-angle rotation of a jaw and keep the drag chain in straight forward and backward movement at all times, so as to meet the change of the posture of the jaw required by complex draping processing and avoid the damage of the drag chain caused by the rotation of the jaw.

Description

Technical Field

[0001] This invention belongs to the technical field of aircraft skin stretching and forming equipment, specifically relating to a drag chain adaptive swing mechanism for skin stretching equipment. Background Technology

[0002] In existing skin stretching equipment structures, the jaw posture adjustment is mainly achieved by rotating the jaw bending arm around the rear stretching spindle. The jaw is simultaneously connected to a U-shaped arm through which the stretching spindle passes via a cable chain, which limits the stretching stroke and jaw rotation angle within a certain range. However, when dealing with skin designs with complex curved surfaces, this limiting effect of the cable chain can prevent the jaw from meeting processing requirements effectively, and excessive jaw rotation may also damage the cable chain. Summary of the Invention

[0003] In view of this, and in response to the technical problems existing in this field, the present invention provides an adaptive swing mechanism for a cable chain in a Monla device, comprising a slip ring connector; a connecting plate is provided below the slip ring connector, and a ball bearing is provided in the center of the connecting plate. The tension spindle of the Monla device passes through the ball bearing and is fixedly connected to the rear end of the jaw horizontal swing arm, and can rotate within the ball bearing; a cable chain fixing frame is provided above the connecting plate, one end of the cable chain is connected to the cable chain fixing frame, and the other end is fixedly connected to the U-shaped arm of the Monla device.

[0004] Furthermore, a limit groove is provided on the connecting plate, and a corresponding limit ball is provided at the rear end of the horizontal swing arm of the jaws. The two work together to limit the rotation angle of the jaws.

[0005] Furthermore, a guide slide is installed below the cable chain, and a slide support bracket is provided on the U-shaped arm behind the cable chain fixing frame. The guide slide can drive the cable chain to slide back and forth on the upper end of the slide support bracket.

[0006] The adaptive swing mechanism of the cable chain in the Monla equipment provided by the present invention can keep the cable chain moving in a straight line back and forth while realizing the large-angle rotation of the jaws. This can meet the jaw posture changes required for complex skinning processes and avoid cable chain damage caused by jaw rotation. Attached Figure Description

[0008] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0009] like Figure 1 , 2 As shown, the adaptive swing mechanism 1 for a cable chain in a Monla device provided by the present invention includes a slip ring connector 6; a connecting plate 7 is located below the slip ring connector 6, and a ball bearing 11 is disposed in the center of the connecting plate 7. The tension spindle 9 of the Monla device passes through the ball bearing and is fixedly connected to the rear end of the jaw horizontal swing arm, and can rotate within the ball bearing 11; a cable chain fixing frame 5 is provided above the connecting plate 7, one end of the cable chain 2 is connected to the cable chain fixing frame 5, and the other end is fixedly connected to the U-shaped arm 8 of the Monla device. This swing mechanism design allows the jaws to rotate within a large angle range, thereby meeting the processing requirements of some complex-shaped skins with large curvatures and avoiding damage to the cable chain due to jaw rotation.

[0010] In a preferred embodiment of the present invention, a limiting groove is provided on the connecting plate 7, and a corresponding limiting ball 12 is provided at the rear end of the horizontal swing arm of the jaw. The two cooperate with each other to limit the rotation angle of the jaw. When it is necessary to adjust the jaw angle range, it can be achieved simply by replacing the connecting plate with a different limiting groove curvature.

[0011] In a preferred embodiment of the present invention, a guide slide bar 3 is provided below the cable chain 2, and a slide bar fixing bracket 4 is provided on the U-shaped arm at the rear of the cable chain fixing frame 5. The guide slide bar 3 can drive the cable chain 2 to slide back and forth on the upper end of the slide bar fixing bracket 4. This structure can ensure that the cable chain does not shift or twist when the jaws rotate.

[0012] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0013] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0014] It should be understood that the sequence number of each step in the embodiments of the present invention does not imply the order of execution.
