Problems solved by technology

[0004] The present invention is aimed at the problem that it is difficult to support and place the aircraft wing model in the prior art, or the ordinary support device is difficult to adapt to the irregular shape of the wing and the stress is too concentrated. It provides a portable wing self-adaptive support device. There is a ring groove track and a sliding column. The sliding column moves freely in the ring groove track. The locking mechanism is divided into left and right halves, which are fixed on the base through the sliding column. The left and right locking mechanisms are separated by a telescopic rod. Connected and stretched to both sides. Driven by the free movement of the sliding column, the stretched two-petal locking mechanism forms an irregular quadrilateral placement area to adapt to the placement support of the wing model, reduce stress concentration, and avoid excessive deformation. Realize adaptive tightening, fixing and supporting functions

Embodiment 1

[0030] A portable wing adaptive support device, such as figure 2 As shown, it includes a bottom plate 1, a support rod 2, a base 3 and a locking mechanism 4. The base 3 is suspended above the bottom plate 1 through the support rod 2, and the locking mechanism 4 is fixed on the base 3. The side of the locking mechanism 4 With fan-shaped guardrail 5, such as figure 2 and image 3 As shown, the inner side of the base 3 is provided with a ring groove track 6 and a sliding column 7, and the sliding column 7 moves freely in the ring groove track 6. Therefore, the left and right petals of the locking mechanism 4 can be driven by the movement of the sliding column 7 below, and the two petals can be fitted or separated. The left and right two petals of the locking mechanism 4 are connected by telescopic rods and stretched to both sides , the telescopic rod includes an upper telescopic rod 8 and a lower telescopic rod 9, the upper telescopic rod 8 and the lower telescopic rod 9 are ...

Embodiment 2

[0032] The difference between this embodiment and embodiment 1 is: as Figure 4 and Figure 5 As shown, the positioning pin 13 of this embodiment includes a boss 14 and a groove 15, as Figure 4 As shown, the boss 14 is located on the lower telescopic rod 9, and the groove 15 is located on the upper telescopic rod 8. The boss 14 and the groove 15 are matched and anchored, which strengthens the connection between the upper telescopic rod 8 and the lower telescopic rod 9. The connection stability ensures the telescopic movement of the upper and lower telescopic rods, thereby further ensuring the safety of the support device of this implementation rate, which is more stable and reliable.

[0033] In addition, if Image 6 As shown, the upper telescopic rod 8 and the lower telescopic rod 9 are respectively provided with an upper telescopic rod positioning hole 16 and a lower telescopic rod positioning hole 17, and the upper telescopic rod positioning hole 16 and the lower telesco...

Embodiment 3

[0035] The difference between this embodiment and Embodiments 1 and 2 is that it also includes a positioning caliper 18, such as Image 6 As shown, the two ends of the positioning caliper 18 are provided with a fixed buckle 19, and the fixed buckle 19 can be engaged and fixed in the upper telescopic rod positioning hole 16 and the lower telescopic rod positioning hole 17. The main function of the positioning caliper 18 here is to further Fix the telescopic angle and length of the upper and lower telescopic rods, control the stability of the upper and lower telescopic rods, further improve the firmness of the support device, improve the working efficiency of the device, and be more efficient and safe.

[0036] At the same time, if image 3 As shown, the support rod 2 is specially set to be retractable, and the up and down height of the support rod 2 is adjusted by the switch knob 21, which is more convenient for the placement of wings of different types and models, so that the ...

Abstract

The invention discloses a portable self-adaption supporting device of a wing. The device comprises a bottom plate, a supporting rod, a base and a clamping mechanism, the base suspends above the bottomplate through the supporting rod, and the clamping mechanism is fixed to the base; the side of the clamping mechanism is provided with a fan-shaped protecting fence; an annular groove rail and a slide column are arranged on the inner side of the base, the slide column freely moves in the annular groove rail, the clamping mechanism is divided into left and right parts, and the slide column is fixed to the base; the left and right clamping mechanism parts are connected through a telescopic rod and stretch toward the two sides, the stretching left and right clamping mechanism parts are driven byfree motion of the slide column to form an irregular quadrangular placing area so as to adapt to placing and supporting of a wing model, stress concentration is reduced, too large deformation is avoided, and the functions of self-adaption fastening, fixing and supporting are achieved.

Description

technical field [0001] The invention relates to a support device, in particular to a portable wing self-adaptive support device which is convenient for placing and supporting an aircraft wing model. Background technique [0002] When the wing model with a large aspect ratio is placed statically, due to the influence of the wingspan being too long, the wing structure generally undergoes large-scale flexible deformation and droops downward. This phenomenon will cause unfavorable The estimated damage will also directly affect the experimental data measurement. In addition, when the wing is in an unprotected state, the amount of deformation obtained by the wing may cause the wing tip to contact the ground directly due to excessive deformation, thus cause structural damage. [0003] At present, for this situation, the general solution is to set a simple support mechanism in the middle of the wing model as a structural support. Although this solution solves the problem of wing dr...
