Description

Technical Field

[0001] This utility model belongs to the field of composite material manufacturing, specifically, it relates to a clamping device for auxiliary positioning of molds. Background Technology

[0002] Composite sandwich structures possess a high strength-to-weight ratio and are commonly used in secondary load-bearing components of aircraft. The molding process primarily involves secondary bonding. During the secondary bonding process of composite sandwich structural components (hereinafter referred to as structural components), the internal parts require positioning due to structural requirements. Positioning devices are typically used to constrain the position of these parts, and these devices are fixed to the bonding mold panel of the structural component using positioning pins and bolts. However, during the molding process, due to curing pressure and the influence of the mold structure, the internal parts may tilt to a certain extent as the positioning device flips outward. Summary of the Invention

[0003] In view of the above-mentioned prior art, the purpose of this utility model is to overcome the shortcomings of the prior art, adapt to the actual needs, and thus provide a clamping device for auxiliary positioning of molds.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a clamping device for auxiliary positioning of a mold, comprising a support, a clamping screw, a clamping head, and fasteners. The upper end of the support is provided with a first threaded hole for the clamping screw to pass through, and the bottom is provided with at least two positioning holes for the fasteners to pass through. One end of the clamping screw passes through the first threaded hole on the support and is movably connected to one end of the clamping head. Rotating the other end of the clamping screw can push the clamping head closer to the positioning device on the mold. The other end of the clamping head clamps the positioning device on the mold. The support is fixed to the bonding mold panel of the structural component by fasteners passing through the positioning holes at the bottom of the support.

[0005] Furthermore, it also includes a support plate, a movable handle, and a circular block. The support plate is fixed on the support, and the circular block is fixed on the upper end of the support. The middle of the circular block is provided with a second threaded hole for the clamping screw to pass through, and the second threaded hole on the middle of the circular block is concentrically set with the first threaded hole on the upper end of the support. The movable handle is connected to the other end of the clamping screw. Rotating the movable handle can push the clamping head close to and clamp the positioning device on the mold.

[0006] Furthermore, the support includes a first corner seat and a second corner seat. The first corner seat and the second corner seat are welded together to form an L-shaped support. The second corner seat is located at the bottom of the first corner seat. A positioning hole is provided on the second corner seat. A round block is welded to the upper left side of the upper end of the first corner seat. A first threaded hole is provided on the upper end of the first corner seat.

[0007] Furthermore, the fasteners are screws, and there are four positioning holes. The support is fixed to the bonding mold panel of the structural component by screws passing through the positioning holes on the second corner seat.

[0008] Furthermore, the support plate is a right-angled triangle, and the two straight sides of the support plate are welded to the right side of the first corner seat and the upper end of the second corner seat, respectively.

[0009] Furthermore, the diameter of the second threaded hole in the middle of the round block and the diameter of the first threaded hole on the upper end of the first corner seat are both matched with the outer diameter of the clamping screw.

[0010] Furthermore, the clamping head is shaped like an inverted trumpet.

[0011] Furthermore, the active handle is a "straight-line" active handle.

[0012] Furthermore, the first corner bracket, the second corner bracket, and the circular block are made of the same material, and the thickness of both the first corner bracket and the second corner bracket is not less than 10mm.

The first corner seat and the second corner seat are welded together for mounting the clamping screw. The support plate is used to strengthen the welded structure of the first corner seat and the second corner seat. The clamping screw is used to adjust the forward and backward movement of the clamping head. The round block enhances the stability of the clamping screw during movement. The clamping head is used to push the positioning device on the mold into the positioning position. The screw is used to fix the clamping device of this utility model.

[0014] The beneficial effects of this utility model are as follows: This device features a simple structure and convenient operation, enabling rapid installation and disassembly without affecting the airtightness of the vacuum bag assembly during the bonding process of structural components.

(3) Concentric internal threaded holes (i.e., first threaded hole 10 and second threaded hole 11) are opened on the first corner seat 1 and the round block 7. The height of the threaded holes (i.e., first threaded hole 10 and second threaded hole 11) should take into account the overall height of the positioning device 12. Positioning holes 9 are opened on the second corner seat 2 as needed. The clamping device is installed on the structural component bonding mold panel 13 through the positioning holes 9 using screws 8. (4) The clamping screw 4 is fitted onto the support through the threaded holes (i.e., the first threaded hole 10 and the second threaded hole 11) on the first angle seat 1 and the round block 7; (5) Install a movable clamping head 6 at one end of the clamping screw 4. The clamping head 6 is in the shape of an inverted flared mouth and is used to clamp the positioning device 12 on the mold. Install a "one-line" movable handle 5 at the other end. (6) Pressing device usage process: The internal parts (beams, ribs, etc.) of the composite material structure are positioned theoretically using the positioning device, and then vacuum bag assembly is performed to ensure airtightness; the pressing device of this utility model is fixed on the panel 13 of the adhesive mold of the structural component by the mounting screw 8, and the movable handle 5 is rotated so that the pressing screw 4 drives the pressing head 6 to move forward and approach the vacuum bag surface outside the positioning device 12 on the mold.
