Laying twirling strips on the acute angle line, compacting the laid twirling strips, and adhering a guide arc to the truss and the skin surface for adhesive bonding reinforcement. The existing twisting strips are mostly compacted manually, so that the long strip-shaped truss is difficult to operate, the compaction effect is poor, and the problem of stress concentration cannot be effectively solved.

Disclosure of Invention

The utility model aims at solving the problem that exists among the prior art, provide one kind and be used for cap type truss and covering co-curing in-process to carry out compaction, lead the circular arc to truss and covering internal twist strip, reduce the solidification stress concentration's twist strip gyro wheel extrusion school shape device.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a twister strip roller extrusion sizing device is characterized in that a twister strip is laid on a spliced hat-shaped stringer and an included angle line in an inner cavity of a skin and comprises a roller and a main body bracket; the roller is used for extruding and correcting the twister strip; one end of the main body support is rotatably connected with the roller, and a traction rope is bound on the main body support and used for drawing the main body support to drive the roller to extrude the shape-correcting twister strip.

Preferably, the main body support is rectangular, notches are formed in two opposite side edges of the main body support, springs are connected in the notches and comprise a spring I and a spring II, and the springs are used as one part of the side edges of the main body support.

Further, the device also comprises a guiding device for guiding the traction rope to continuously slide in the inner cavity.

Preferably, the number of guides is 3, two of which are provided on the top of the hat stringer and on the skin, respectively, at opposite positions, and the other of which is provided on the side of the hat stringer at a position corresponding to the rollers.

Preferably, the guiding device is a sliding bearing, which comprises a sliding bearing I, a sliding bearing II and a sliding bearing III.

Compared with the prior art, the utility model has the advantages of as follows: the device is characterized in that the device slides in an inner cavity formed by the hat-shaped stringer and the skin through a sliding bearing, meanwhile, a spring roller rolls to apply pressure to the passing twister strip to compact the twister strip between an included angle of the truss and the skin and form an arc chamfered edge of the roller radius, and the device applies pressure to the laid twister strip uniformly and continuously under the traction of a traction rope. The purposes of compacting and arc guiding of the twill strips are achieved, the phenomenon of internal angle stress concentration after the product is solidified is reduced, and the product quality is effectively improved.

Drawings

FIG. 1 is a schematic structural diagram of an embodiment of the present invention;

in the figure, 1, a roller; 2. a spring I; 3. a spring II; 4. a main body support; 5. a sliding bearing I; 6. a sliding bearing II; 7. and a sliding bearing III.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawing 1: a roller extrusion sizing device for twister strips comprises a roller 1, a spring I2, a spring II 3, a main body support 4, a sliding bearing I5, a sliding bearing II 6 and a sliding bearing III 7; the axle center of the roller 1 and the main body bracket 4 can be rotatably arranged, namely, the main body bracket 4 can drive the roller to rotate under the action of external force; the main body support 4 is rectangular, one side of the main body support passes through the axle center of the roller and is rotatably connected with the roller, openings are formed in two sides of the main body support, and a spring I2 and a spring II 3 are connected and fixed in the openings, namely the spring I2 and the spring II 3 are respectively used as part of the side of the main body support 4; slide bearing I5 sets up in hat type stringer top, and slide bearing II 6 sets up in the side of hat type stringer, and slide bearing III 7 sets up on the covering, and relative with slide bearing I5, and slide bearing I5, slide bearing II 6 and slide bearing III 7 all regard as the guiding device who draws the rope, and the quantity of drawing the rope is 3, with slide bearing I, slide bearing II, slide bearing III one-to-one, and be connected fixedly with main part support 4's the limit that corresponds respectively.

The working process is as follows:

1. the roller 1 applies pressure to the twisted strips passing through the elastic support of the spring, and the twisted strips are compacted between the included angle of the truss and the skin and form the arc chamfered edge of the roller radius;

2. the device slides in an inner cavity formed by the hat-shaped stringer and the skin through the sliding bearing under the traction of the traction rope, and uniformly and continuously applies pressure to the laid twister strip.
