Description

Technical Field

[0001] This utility model relates to a template storage and usage rack for adhesive fasteners of composite honeycomb sandwich panels, belonging to the field of composite material manufacturing technology. Background Technology

[0002] Composite honeycomb sandwich panels consist of a honeycomb core and upper and lower fiberboards. They have advantages such as light weight, corrosion resistance, sound insulation, and flame retardancy. Fasteners can be glued to them to connect with other components, and they can be disassembled, repaired, and replaced after connection. They are widely used in the aerospace field, and the floors of some large civil aircraft are processed and manufactured using composite honeycomb sandwich panels.

[0003] There are two methods for installing fasteners on composite honeycomb sandwich panels: pre-embedded fasteners and post-embedded fasteners. Post-embedded fasteners can be further divided into mechanical connections and adhesive bonding. Adhesive bonding fasteners usually require the use of templates for positioning and installation. That is, fastener installation holes are first drilled in the composite honeycomb sandwich panel, and then the fasteners are glued to the composite honeycomb sandwich panel through the fastener installation positioning holes on the template. However, since the installation position and size specifications of the fasteners are different on each composite honeycomb sandwich panel, a dedicated fastener installation positioning template is often required for each composite honeycomb sandwich panel. This results in a large number of templates. In actual engineering applications, in order to improve production efficiency, multiple templates are provided for each composite honeycomb sandwich panel, which further increases the number of templates. A large number of templates means that more space is needed for storage, and more time is spent on retrieval and use, thus increasing the difficulty and cost of management. Utility Model Content

[0030] It should be noted that the terms "upper", "lower", "left", "right", etc. are used to describe the situation as shown in the accompanying drawings or in the usual usage state, and those skilled in the art should understand them in accordance with the technical solution of this utility model.

[0031] The following is in conjunction with the appendix Figure 1-8 Further details of this utility model: A template storage and use rack for adhesive fasteners of composite honeycomb sandwich panels, comprising a main support frame, an auxiliary support frame, and a connecting base plate 12; the main support frame includes a main base plate 1, a main rod 2, and a main rotating clamping plate 3, and the auxiliary support frame includes an auxiliary base plate 10, an auxiliary rod 9, and an auxiliary rotating clamping block 8; as shown Figure 3 As shown, the main rotating clamping plate 3 includes a rotating bushing 19, a clamping plate 18, and a template slot 20, as follows: Figure 6 As shown, the auxiliary rotating block includes a rotating bushing 19, a locking block 25, and a locking slot 26.

[0032] The specific structure is as follows:

[0033] A matching locking nut is placed in the countersunk hole 16 of the main rod locking nut at the bottom of the main chassis 1. The connecting base plate 12 is placed on the main chassis 1 and the auxiliary chassis 10. The main rod 2 is installed on the main chassis 1 through the main rod insertion hole 30 on the connecting base plate 12 and fixed with the positioning screw 13 through the positioning hole 31 on the connecting base plate. The auxiliary rod 9 is installed on one of the support platforms 27 of the auxiliary chassis 10 through the auxiliary rod insertion thread hole 29 on the auxiliary chassis 10 and fixed with the fixing pin 11. The main rotating clamping plate 3 is installed on the main rod 2 through the rotating bushing 19. The auxiliary rotating clamping block 8 is installed on the auxiliary rod 9 through the rotating bushing 19. The auxiliary support plate 6 is installed in the two middle slots 26 on the auxiliary rotating clamping block 8 and fixed with the pins 7 respectively. In this way, the template for storing and using the composite honeycomb sandwich panel adhesive fasteners is assembled.

[0034] like Figure 2 As shown, the main chassis 1 needs to have a certain bottom area and weight to ensure that the main rod 2, connecting base plate 12 and multiple templates 4 will not tip over after being installed on the main chassis 1 without the auxiliary rod 9, auxiliary chassis 10 and auxiliary support plate 6. The center of the upper end face of the main chassis 1 has a main rod insertion threaded hole 14 and a positioning screw hole 15 for positioning the connecting base plate 12. The center of the lower end face has a main rod locking nut countersunk hole 16 for locking the main rod 2. The middle of the side has a positioning screw hole inspection groove 17 for checking whether the positioning screw 13 is installed in place. This prevents the connecting base plate 12 from swinging due to improper positioning, which could cause safety hazards, and facilitates the removal and handling of the main chassis 1.

[0035] like Figure 3As shown, the rotating bushing-19 of the main rotating clamping plate 3 needs to match the main rod 2 to ensure that the main rotating clamping plate 3 can be smoothly installed and removed from the main rod 2, and that the template 4 can be smoothly rotated around the main rod 2 by hand after installation. The upper and lower end faces of the rotating bushing 19 need to be higher than the upper and lower surfaces of the clamping plate 18 by a certain height to facilitate the rotation, use, and removal of adjacent templates 4 after installation. The template slot 20 on the clamping plate 18 needs to match the template wedge end 21 on the template 4 so that the template 4 can be smoothly installed into the template slot 20. The overall length of the clamping plate 18 needs to be determined according to the outer dimensions of the template 4 to ensure that it can meet the installation of different templates 4.

[0036] like Figure 6 As shown, the rotating bushing 19 of the auxiliary rotating block 8 needs to match the auxiliary rod 9 to ensure that the auxiliary rotating block 8 can be smoothly installed and removed on the auxiliary rod 9. The height of the rotating bushing 19 is the same as that on the main rotating plate 3. After the auxiliary rotating block 8 is installed, the middle two of the six slots 26 on its block 25 are required to match the height of the lower surface of the template 4 installed on the corresponding main rotating plate 3 after the auxiliary support plate 6 is installed, so as to ensure that the auxiliary support plate 6 can provide certain auxiliary support to the template 4.

[0037] like Figure 5 As shown, the auxiliary support plate 6 needs to have a certain thickness and length. While meeting the strength requirements, it should have as many limiting holes 23 as possible. The diameter of the limiting holes 23 should be larger than the fastener positioning holes 22 on the template 4 to facilitate the installation of the limiting pins.

[0038] like Figure 7 As shown, the overall height of the auxiliary chassis 10 is the same as that of the main chassis -1, and it has a certain length and width. The two support platforms 27 on it need to have the same auxiliary rod insertion threaded holes 29 that match the auxiliary rod 9 to facilitate the installation of the auxiliary rod 9. A transport hole 28 is opened between the two support platforms 27 to facilitate the removal and transport of the auxiliary chassis 10.

[0039] like Figure 8 As shown, one end of the connecting base plate 12 has a main rod inlet hole 30 for mounting the main rod 2 onto the main chassis 1 and a connecting base plate positioning hole 31. The remaining positions have connecting auxiliary chassis positioning holes 32 that match the auxiliary rod insertion threaded holes 29 on the auxiliary chassis 10, so as to meet the position adjustment requirements of the auxiliary chassis 10.

[0040] like Figure 4 As shown, in addition to serving as a positioning fastener for the composite honeycomb sandwich panel, template 4 also needs to be provided with a template wedge-shaped clamping end 21 on one side to facilitate installation onto the main rotating clamping plate 3.

[0041] The connecting base plate 12 is mounted on the main base 1 and the auxiliary base 10 via the main rod 2 and the fixing pin 11. The main rotating clamping plate 3 is mounted on the main rod 2 via the rotating bushing 19. The template 4 for the composite honeycomb sandwich panel adhesive fastener is mounted on the template slot 20 of the main rotating clamping plate 3 via the template wedge-shaped clamping end 21. The position of the auxiliary base 10 is adjusted according to the size of the template 4 for the composite honeycomb sandwich panel adhesive fastener through the transport hole 28 on the transport auxiliary base 10 and the connecting base plate 12 positioning hole 32. The auxiliary rod 9 is mounted on another support platform 27 of the auxiliary base 10 via the auxiliary rod insertion thread hole 29. The auxiliary rotating clamping block 8 is mounted on the auxiliary rod 9 via the rotating bushing 19. The auxiliary support plate 6 is mounted on the auxiliary rotating clamping block 8 via the clamping slot 26 on the auxiliary rotating clamping block 8. The pin 7 is used to connect and fix it through the pin hole 24. The other end of the auxiliary support plate 6 is placed on the composite honeycomb sandwich panel adhesive fastener. Below the template 4, position it appropriately so that the template 4 can be positioned and supported by the limiting pin 5 through the fastener positioning hole 22 on the template 4 and the limiting hole 23 on the rotating auxiliary support plate 6. According to the height of the main rod 2 and the auxiliary rod 9, multiple main rotating clamping plates 3, auxiliary rotating clamping blocks 8, auxiliary support plates 6, limiting pins 5 and pins 7 are used to store multiple templates 4 for bonding and fastening composite honeycomb sandwich panels. When using a template 4 for bonding and fastening composite honeycomb sandwich panels, remove the limiting pin 5 on top and rotate it 180° until there is no template 4 on the side of the main rod 2. This ensures the storage and use of multiple templates 4 for bonding and fastening composite honeycomb sandwich panels and saves on the space occupied and the management costs of finding, picking up and moving them.
