Embodiment 1

[0044] like figure 1 As shown in ~ 6, according to the size and shape of the special-shaped member 16, insert the three limiting inserts 1 into the universal bottom plate 2 in sequence, and rotate the inserts 1 in turn so that the insertion protrusion on the insert 1 does not correspond to the socket 3, Make the plug-in 1 snap into the universal bottom plate 2, rotate the limit part 6 of the plug-in 1, make the limit part 6 close to the universal bottom plate 2, and fix the plug-in 1. Then place the special-shaped component 16 close to the plug-in 1 that has been inserted into the universal bottom plate 2, then continue to insert the plug-in 1 on the side or hollow of the special-shaped component 16, and repeat the steps of rotating the plug-in 1 and rotating the stopper 6, so that the stopper 6 is pressed. Tighten the special-shaped member 16 to limit the special-shaped member 16 to be fixed on the universal base plate 2 . According to the shape of the parts, plug-ins 1 are...

Embodiment 2

[0048] This embodiment is improved on the basis of Embodiment 1. The improvement is that: the support shaft includes a square mandrel 4 and a threaded tube 9 fixedly sleeved on the square mandrel 4; The surface is provided with an external thread that is threadedly connected with the stopper 6, and the threaded tube 9 is provided with a square hollow hole 8 that interferes with the square mandrel 4, and the mandrel 4 extends along the axis of the threaded tube 9 and is inserted into the Part 7 is fixedly connected. After being threaded into the limiting part 6, the square mandrel 4 can be locked with an inner square wrench, and the tightening effect is better.

[0049]The limiting protrusion 13 on the limiting part 6 is provided with a plurality of limiting grooves 14 on the side away from the support shaft, and the insertion protrusion 10 on the insertion part 7 is provided with a plurality of grooves 11 on the side away from the supporting shaft. The limit part 6 is provide...

Embodiment 3

[0062] This embodiment is improved on the basis of Embodiment 1. The improvement is that: the insertion part 7 is provided with a flexible rope 19 nested into the limiting groove 14 to realize the positioning and fixing of the parts placed on the back of the bottom plate. ; Make the back of the universal bottom plate 2 also available for fixing parts, increase the utilization rate of the device, and reduce costs.

[0063] The specific spacing and fixing method of required spacing and fixed special-shaped member 16 are:

[0064] Step A: insert the plug-in 1 into the bottom plate;

[0065] Step B: Rotate the plug-in 1 as a whole until the insertion protrusion 10 does not correspond to the socket 3;

[0066] Step C: Use the inner square wrench to lock the square mandrel 4, and rotate the limit part 6 until the limit part 6 is close to the universal bottom plate 2;

[0067] Step D: Place the special-shaped member 16 so that the side or hollow of the special-shaped member 16 is c...

Abstract

The invention discloses an adjustable limiting and fixing method of an irregular component. The method is characterized in that an inserting part capable of limiting and fixing the irregular componentis inserted into a general bottom plate based on the shape of the irregular component, wherein a plurality of irregular inserting holes are formed at equal intervals in the general bottom plate; theinserting part comprises a supporting shaft, an inserting part which fixedly sleeves the supporting shaft, and a limiting part which rotatably sleeves the supporting shaft through threads; the side surfaces of the inserting part and the limiting part are provided with at least one inserting bumps; when limiting and fixing the irregular component, the inserting part of the inserting part passes through the general bottom plate through the corresponding irregular inserting holes; the inserting part can be rotated to enable the inserting part to be clamped to the rear surface of the general bottom plate, and the limiting part can be rotated to compress the irregular component. According to the method, the general bottom plate provided with the inserting holes and the inserting part which canbe inserted are utilized for limiting and fixing parts, so that the demands on limiting and fixing of different parts of aviation structural components can be met; and meanwhile, the generality is high; the limiting and fixing demands of different parts are met; the method is economic and feasible.

Description

technical field [0001] The invention belongs to the field of aviation special component processing, and in particular relates to an adjustable limit and fixing method for special-shaped components. Background technique [0002] In the current production process of aerospace structural parts, more attention is paid to the dimensional accuracy and surface quality of parts, while zero [0003] There are less concerns about transshipment and storage after the parts are processed. During the transfer process, the parts are mostly loose, randomly stacked, and exposed. Parts are often damaged or even scrapped due to scratches and bruises. Since aeronautical structural parts are mostly high-value parts, the resulting losses are great. [0004] Due to the small batch size and variety of aviation structural parts, and the huge difference in shape and size, if each part is specially designed [0005] If the limit and fixed protection devices are not used, a large number of special a...
