Description

Integrated control rocker arm

Technical Field

The utility model belongs to control surface design field, concretely relates to rocking arm is controled in integration.

Background

In order to ensure load transfer, the control surface root manipulation and installation usually comprises parts such as a rocker arm, a tubular beam, a reinforcing corner box and the like, and all the parts are connected through bolts and then connected with end ribs, an upper wall plate and a lower wall plate through bolts. The connection of rocker arm and tubular beams, reinforcing angle box need structurally make the hole, cause hole limit stress concentration, need carry out extra structural reinforcement to arouse the structure and increase weight.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: an integrally operating rocker arm is provided to prevent stress concentration.

The technical scheme is as follows:

in a first aspect, there is provided an integrally steered rocker arm comprising: the control surface comprises a tubular beam, a double-lug control joint and a control surface body butt joint piece, wherein the double-lug control joint is arranged on the outer side wall of the tubular beam, and the control surface body butt joint piece is arranged on the outer side of the end part of the tubular beam.

Further, control surface body butt-joint piece includes first cambered surface section, second cambered surface section and worker's type section, and wherein, first cambered surface section sets up along the lateral wall horizontal extension on the tubular beams, and the second cambered surface section sets up along the lateral wall horizontal extension under the tubular beams, and the last flange strip and the lower flange strip of worker's type section are connected with first cambered surface section and second cambered surface section respectively.

Further, the first cambered surface section is connected with the front edge upper skin through a fastener.

Further, the second cambered surface section is connected with the front edge lower skin through a fastener.

Furthermore, the upper and lower edge strips of the I-shaped section are respectively connected with the upper and lower wall plates through fasteners.

Further, the webs of the drum sections are connected to the beams by fasteners.

Has the advantages that:

the utility model discloses with the part of rocking arm wholeization design one-tenth, reduced part quantity, reduced structure weight, less stress concentration, improvement comprehensive bearing capacity.

Detailed Description

As shown in fig. 1, in order to ensure load transmission, the control surface root manipulation and installation usually includes parts such as an end rib 11, a rocker arm 12, a tubular beam 13, a reinforcing corner box 14, etc., and the parts are connected by bolts and then connected with the end rib, an upper wall plate and a lower wall plate by bolts. The connection of the rocker arm 12 to the tubular beam 13 and the reinforcing corner box 14 requires holes to be made in the structure, causing stress concentration at the edges of the holes and additional structural reinforcement, thereby causing structural weight increase.

In order to solve the problem the utility model discloses make up rocking arm, tubular beam, enhancement angle box into a part, the comprehensive consideration bearing capacity and processing property make it satisfy the design demand. The purpose is to reduce the number of parts, reduce the structure weight, reduce the stress concentration and improve the comprehensive bearing capacity.

Referring to fig. 2, the integrated control rocker arm body is connected with parts such as a control surface upper wall plate 21, a lower wall plate 22, a front edge upper skin 23, a front edge lower skin 24, a beam, an end rib and the like, and the double lugs iii are connected with a control actuating cylinder to transmit the control force to the control surface and control the deflection of the control surface.

The upper surface and the lower surface (two arc surface sections) of the arc area I of the integrated control rocker arm are respectively connected with the front edge upper skin and the front edge lower skin and are used for supporting the front edge skin. The upper end face II and the lower end face of the integrated control rocker are respectively connected with the upper wall plate and the lower wall plate of the control surface;

referring to fig. 3 and 4, the inner cavities IV and V of the circumference of the pipe beam of the integrated control rocker arm are respectively connected with the beam flange strip and the beam web, and the inner cavities VI and VI of the extending sections are respectively connected with the end rib flange strip and the end rib web.
