Technical Field
[0001] This utility model relates to the field of tooling technology, and in particular to a pre-embedded positioning tooling for forming composite material reflectors. Background Technology
[0002] Satellite reflectors are structural elements in satellite antennas used for receiving and transmitting external signals. Therefore, their surfaces contain numerous embedded components. Traditional reflectors are made of metal, and the embedded components can be machined later to ensure their position and structural accuracy. However, metal reflectors are costly to manufacture and bulky, hindering the transportation and maintenance of satellite antenna structures. When using composite materials to fabricate reflectors, numerous embedded nuts are distributed on the reflector surface. Current technology lacks tooling to accurately install these nuts onto the reflector. Therefore, a reflector forming and positioning tooling is urgently needed to assist in accurately embedding the nuts in their corresponding positions on the reflector. Utility Model Content

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.
[0023] Example 1: Refer to Figures 1-3 , Figure 5 and Figure 6 This is the first embodiment of the present invention. This embodiment provides a pre-embedded positioning fixture for forming composite material reflectors, including a main component 100, including a main base frame 101. A laying base plate 102 for laying reflectors is fixedly connected to the upper side of the main base frame 101. Two first flange plates 103 spaced apart in the front-back direction are fixedly connected to the upper side of the laying base plate 102. Two second flange plates 104 spaced apart in the left-right direction are fixedly connected to the upper side of the laying base plate 102 between the two first flange plates 103. Several sets of pre-embedded component positioning components 200 for positioning pre-embedded components are provided above the laying base plate 102. The pre-embedded components in this application are preferably pre-embedded nuts.
[0024] Specifically, the embedded part positioning assembly 200 includes an embedded part positioning component 202. The embedded part positioning component 202 includes two embedded part positioning plates 2021 spaced apart in the left and right directions. Several positioning ears 208 are fixed on the embedded part positioning plates 2021. Positioning sleeves 207 are fixedly connected to the positioning ears 208. The downward end of the positioning sleeve 207 has an insertion groove 2072 for connecting the embedded part.

The positioning sleeve 207 on the upper side of the connecting through hole has an installation hole 2071. The outer diameter of the installation hole 2071 is larger than that of the connecting through hole.
[0025] After the embedded part positioning plate 2021 is fixed on the base plate 102, the positions of the positioning ears 208 correspond one-to-one with the required positions of the embedded parts. After the required prepreg is laid and vacuuming is completed in the laying area enclosed by the first flange plate 103 and the second flange plate 104, the embedded nuts are installed onto the positioning sleeves 207. Specifically, the upward-facing end of the embedded nut is inserted into the insertion groove 2072, and the upper end of the embedded nut abuts against the step of the positioning sleeve 207 on the upper side of the insertion groove 2072. The positioning bolts 2021 are then tightened. 9. After inserting the mounting hole 2071 and the connecting through hole, screw the pre-embedded nut into the pre-embedded nut to fix it relative to the positioning sleeve 207. Apply 1-2 layers of adhesive film to the surface of the pre-embedded nut that contacts the prepreg, with the outer edge of the adhesive film extending beyond the outer edge of the contact surface. Align the pre-embedded part positioning parts 202 one by one with the mounting positions on the base plate 102 to fix the pre-embedded part positioning plate 2021 relative to the base plate 102.
