Abstract
The invention discloses a connection method for a rib plate tail end and a mast of a radial rib antenna and a die, and belongs to the technjical field of a radial rib antenna. The problem that a multi-angle irregular fold line or even the tearing phenomenon easily occurs in the processes of curling, folding and unfolding of a rib plate caused by uneven stress due to the fact that the rib plate tail end and the mast of the existing radial rib antenna are connected by a metal piece or are made of a one-step forming carbon fiber material, thus the transmit-receive quality of the antenna signal is influenced, as well as the problems that the one-step forming carbon fiber material requires a large die and is high in cost are solved. The connection method adopts aramid cloth to bond the mast and the rib plate tail end in an interdigital way and a precise positioning method for the die is adopted, the mast and the rib plate are precisely connected. The connection method for the rib plate tail end and the mast of the radial rib antenna and the die are used for connecting the rib plate tail end with the mast of the radial rib antenna.
Description
Technical field
The invention belongs to radial rib antenna technical field, be specifically related to a kind of floor tail end of radial rib antenna and method of attachment and the mould of mast.
Background technology
Radial rib antenna has lightweight, bore is large, cost of transportation is low, the advantage that precision is high, but at present the floor tail end of radial rib antenna adopts metalwork to connect with being connected of mast or adopts one-shot forming carbon fibre material, in floor curling folding and expansion process, easily because unbalance stress produces the irregular scrimp of multi-angle, even tear phenomenon, thereby affect the transmitting-receiving quality of aerial signal, and the mould of one-shot forming carbon fibre material is large, cost is high.
Summary of the invention
The object of the invention is adopt metalwork to connect with being connected of mast or adopt one-shot forming carbon fibre material in order to solve the floor tail end of current radial rib antenna, in the curling folding and expansion process of floor, easily because producing the irregular scrimp of multi-angle, unbalance stress even tears phenomenon, thereby affect the transmitting-receiving quality of aerial signal, and the mould of one-shot forming carbon fibre material is large, the problem that cost is high, a kind of floor tail end of radial rib antenna and method of attachment and the mould of mast are provided, and its technical scheme is as follows:
The floor tail end of radial rib antenna and a method of attachment for mast, what it adopted is that aramid fiber cloth is bonding by mast and floor tail end finger-fork type, and uses the pinpoint method of mould, and floor tail end is accurately connected with mast.
The floor tail end of radial rib antenna and a connecting mold for mast, it comprises template, at template surface, is provided with mast groove and floor groove; Described mast groove is arranged on the centre position of template surface, and described floor groove has two, and two floor grooves are relatively arranged on the both sides of mast groove, two relative sides of floor groove, is respectively arranged with aramid fiber cloth thickening groove; The cross section of described mast groove is semicircle, the radius that its radius equals mast adds the thickness of used aramid fiber cloth, the shape of described floor groove is coincide with the shape of the floor tail end that uses, its degree of depth by half of use floor tail end thickness, the degree of depth of described aramid fiber cloth thickening groove by a false add of use floor tail end thickness two-layer the thickness of use aramid fiber cloth.
Beneficial effect of the present invention is: without metalwork, connect, do not affect the transmitting-receiving quality of aerial signal, low cost of manufacture, use mould location, connects precisely, and is connected firmly, lightweight, curling folding and can be because distortion aramid fiber cloth produces even jackknifing of scrimp while launching, mould therefor volume be little, and cost is low.

embodiment:
Referring to figs. 1 through Fig. 5, a kind of floor tail end of radial rib antenna and the method for attachment of mast, what it adopted is that aramid fiber cloth 2 is bonding by mast 3 and floor tail end 4 finger-fork types, and uses the pinpoint method of mould 1, and floor tail end 4 is accurately connected with mast 3.
The first step, pastes aramid fiber cloth 2 after one week to sticky around mast 3;
Second step, after glue is dry, 2 pairs of sticky places of aramid fiber cloth are trimmed to consistent with the shape of floor tail end 4, and be cut into some parts of wide cloth 2-1 perpendicular to mast 3, in floor tail end 4 and every cloth 2-1 corresponding section, several otch 4-1 is set, the width of otch 4-1 is 1/2nd of cloth 2-1 corresponding position width, the setting of aliging of the otch 4-1 that is positioned at floor tail end 4 both sides and the inner side edge of corresponding cloth 2-1, the justified setting of other otch 4-1 and corresponding cloth 2-1, and the otch 4-1 that the otch 4-1 that odd number cloth 2-1 is corresponding is corresponding with even number cloth 2-1 is respectively set to a row, otch 4-1 corresponding to odd number (or even number) cloth 2-1 is 1/2nd of cloth 2-1 length apart from the distance at floor tail end 4 edges, otch 4-1 corresponding to even number (or odd number) cloth 2-1 is 3/4ths of cloth 2-1 length apart from the distance at floor tail end 4 edges,
The 3rd step, mast 3 is placed in the mast groove 1-1 of template 1, cloth 2-1 is divided into odd even two rows, floor tail end 4 is inserted in to odd even two arranges between bar 2-1 and is placed in a side rib plate groove 1-2 of template 1, by the odd number of floor tail end 4 upsides (or even number) cloth 2-1 at position opening corresponding to the otch 4-1 with floor tail end 4, be positioned at the cloth 2-1 of floor tail end 4 both sides in its outer openings, stay inner side 1/2nd width to connect, other cloth 2-1 is at its both-side opening, in the middle of staying, 1/2nd width connect, and opening is following and floor tail end 4 is bonding;
The 4th step, after glue is dry, the odd number of floor tail end 4 upsides (or even number) cloth 2-1 corresponding otch 4-1 from floor tail end 4 is passed, and floor tail end 4 is placed in the opposite side floor groove 1-2 of template 1, make the another side of floor tail end 4 upward, odd number (or even number) the cloth 2-1 that otch 4-1 from floor tail end 4 is passed turns back and is bonding with floor tail end 4, and Using such method is bonding by even number (or odd number) cloth 2-1 and floor tail end 4.
The floor tail end of radial rib antenna and a connecting mold for mast, it comprises template 1, is provided with mast groove 1-1 and floor groove 1-2 on template 1 surface; Described mast groove 1-1 is arranged on the centre position on template 1 surface, described floor groove 1-2 has two, two floor groove 1-2 are relatively arranged on the both sides of mast groove 1-1, two relative sides of floor groove 1-2, are respectively arranged with aramid fiber cloth thickening groove 1-3; The cross section of described mast groove 1-1 is semicircle, the radius that its radius equals mast 3 adds the thickness of used aramid fiber cloth 2, the shape of described floor groove 1-2 is coincide with the shape of the floor tail end 4 that uses, its degree of depth by half of use floor tail end 4 thickness, the degree of depth of described aramid fiber cloth thickening groove 1-3 by a false add of use floor tail end 4 thickness two-layer the thickness of use aramid fiber cloth 2.
The principle of invention: aramid fiber cloth 2 can not exert an influence to aerial signal, and has good corrosion resistance, and impact resistance is strong, anti-dynamic load, the advantage that fatigue behaviour is good; By mould, locate handled easily, and can precisely connect; The width of otch 4-1 on floor tail end 4 be cloth 2-1 width 1/2nd, the otch 4-1 otch 4-1 corresponding with even number cloth 2-1 that odd number cloth 2-1 is corresponding is respectively set to a row, the spacing of two row otch 4-1 are greater than the width of otch 4-1, make the intensity of floor tail end 4 affected by otch 4-1 little.
