Description

Technical Field

[0001] The utility model relates to the technical field of armor manufacturing, in particular to an interlayer bonding and positioning device for a protective composite plate. Background Art

[0002] Composite materials are widely used in aerospace, construction materials, armor protection and other fields due to their high specific strength and specific stiffness. In the field of safety protection, composite materials have gradually replaced the heavy steel protection in the past due to their excellent performance, providing a new solution for safety protection.

[0003] However, in the production process of protective composite panels, the product is often unqualified due to the bonding quality problems between the upper and lower panels. In the process of gluing the composite panels, it is often difficult to accurately align the layers of panels that have been brushed with adhesive at one time. In the process of moving the panels to adjust their positions, the adhesive on the bonding surface of the panels may move, causing damage to the bonding layer.

[0004] In addition, since composite materials are light in texture, gravity alone cannot provide sufficient interlayer pressure, resulting in weak interlayer bonding. In existing production, F-shaped clamps are often arranged around the plates to fix each layer of the plates and provide clamping force to ensure bonding quality. However, this method is cumbersome to operate and lacks lateral positioning during implementation, making it easy for the plates to be misaligned between layers and resulting in poor quality consistency. Utility Model Content

[0005] The utility model aims at the deficiencies in the prior art and provides an interlayer bonding positioning device for a protective composite board, which can limit the misalignment between the layers of the composite board, ensure that each layer of the board is aligned at one time, and can increase the interlayer bonding pressure to ensure the bonding quality, so that the protective composite product can meet the quality requirements.

[0006] The technical solution of the utility model to solve the above technical problems is as follows:

[0007] A device for interlayer bonding and positioning of a protective composite plate, comprising an upper positioning hole provided in an upper plate and a lower positioning hole provided in a lower plate, the upper positioning hole and the lower positioning hole being arranged correspondingly, and the upper positioning hole and the lower positioning hole being connected via a nut, a gasket, a positioning mandrel, and a bolt; the positioning mandrel being slidingly connected to the upper positioning hole and the lower positioning hole, respectively, for positioning; the bolt passes through the bottom of the positioning mandrel, the tail of the bolt passes through the gasket and is threadedly connected to the nut, the gasket abuts against the side of the upper plate away from the lower plate, one end of the positioning mandrel abuts against the side of the lower plate away from the upper plate, and the other end of the positioning mandrel abuts against the gasket, for providing bonding pressure between plate layers.

[0008] By adopting the above technical solution, when performing the plate bonding operation, the operator first inserts the positioning mandrel into the lower positioning hole, and makes one end of the positioning mandrel abut against the side of the lower plate away from the upper plate, and then moves the lower plate to make it close to the upper plate. During the movement, the positioning mandrel is preferentially slidably connected with the upper positioning hole, which limits the movement trajectory of the lower plate, thereby making the lower plate fit well with the upper plate. Then the operator passes the bolts through the positioning mandrel and the gasket in turn, and makes the bolts and nuts threadedly connected to achieve the pressing of the upper plate and the lower plate, which is conducive to improving the bonding stability.

[0009] Furthermore, the positioning core shaft includes an abutment portion, a coarse connection portion, and a fine connection portion, the abutment portion is used to abut against the lower plate, the coarse connection portion is used to connect with the lower positioning hole, and the fine connection portion is used to connect with the upper positioning hole.

[0010] Furthermore, the thick connection portion is matched with the lower positioning hole, and the thin connection portion is matched with the upper positioning hole.

[0011] By adopting the above technical solution, when performing the plate bonding operation, the coarse connecting part is moved and placed in the lower positioning hole, and the fine connecting part is moved and placed in the upper positioning hole. The coarse connecting part is adapted to the lower positioning hole, and the fine connecting part is adapted to the upper positioning hole, which is beneficial to reducing the bonding offset between the upper plate and the lower plate.

[0012] Furthermore, the length of the thick connection portion is smaller than the depth of the lower positioning hole.

[0013] By adopting the above technical solution, the length of the thick connection part is smaller than the depth of the lower positioning hole, so that the thick connection part will not come into contact with the upper plate when limiting the position of the lower positioning hole, thereby improving the applicability of the positioning mandrel.

[0014] Furthermore, a first chamfer is provided at a connection position between the thick connection portion and the thin connection portion, and the first chamfer is arranged along the circumference of the thick connection portion.

[0015] By adopting the above technical solution, when the rough connection part moves into the lower positioning hole, the first chamfer plays a guiding role, so that the rough connection part can be slidably connected with the lower positioning hole more smoothly.

[0016] Furthermore, a second chamfer is formed at a position of the thin connection portion away from the thick connection portion, and the second chamfer is arranged along the circumference of the thin connection portion.

[0017] By adopting the above technical solution, when the thin connection part moves into the upper positioning hole, the second chamfer plays a guiding role, so that the thin connection part can be slidably connected with the upper positioning hole more smoothly.

[0018] Furthermore, the angle between the first chamfer and the second chamfer is 40°-80°.

[0019] Furthermore, a plurality of the upper positioning holes and a plurality of the lower positioning holes are provided.

[0020] By adopting the above technical solution, multiple groups of upper positioning holes cooperate with lower positioning holes, which is conducive to aligning multiple positions of the upper plate and the lower plate at the same time, thereby improving the corresponding accuracy when the upper plate and the lower plate are bonded.

[0021] Furthermore, the upper positioning holes are respectively located at the corners of the upper plate.

[0022] In summary, compared with the prior art, the above technical solution has the following beneficial effects:

[0023] The interlayer bonding positioning device of the protective composite board described in the utility model can effectively limit the interlayer misalignment problem of the composite board, ensure that each layer of the board can be aligned at one time, and at the same time, improve the interlayer bonding pressure, ensure the bonding quality, so that the protective composite product can meet the quality requirements.

[0027] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0028] The utility model embodiment discloses an interlayer bonding and positioning device for a protective composite plate.

[0029] Reference Figure 1 and Figure 2 , an interlayer bonding positioning device of a protective composite plate, comprising an upper plate 3 and a lower plate 4, the upper plate 3 is provided with an upper positioning hole, the lower plate 4 is provided with a lower positioning hole, the upper positioning hole and the lower positioning hole are arranged correspondingly, and a plurality of the upper positioning holes and the lower positioning holes are provided. The upper positioning holes are respectively located at the corner positions of the upper plate 3. Specifically, the upper positioning holes and the lower positioning holes are circular or square. In an embodiment of the utility model, the upper positioning holes and the lower positioning holes are circular.

[0030] The upper positioning hole and the lower positioning hole are connected by a nut 1, a gasket 2, a positioning mandrel 5, and a bolt 6; the positioning mandrel 5 is slidably connected to the upper positioning hole and the lower positioning hole respectively, and is used for positioning; the bolt 6 passes through the bottom of the positioning mandrel 5 through the bolt through hole, and the tail of the bolt 6 passes through the gasket 2 and is threadedly connected with the nut 1. In the embodiment of the utility model, the bolt through hole of the positioning mandrel 5 has a diameter of 17mm, and the bolt 6 and the nut 1 are both M14. The gasket 2 abuts against the side of the upper plate 3 away from the lower plate 4, one end of the positioning mandrel 5 abuts against the side of the lower plate 4 away from the upper plate 3, and the other end of the positioning mandrel 5 abuts against the gasket 2 to provide bonding pressure between the plate layers.

[0031] When performing the plate bonding operation, the operator first inserts the positioning mandrel 5 into the lower positioning hole, and makes one end of the positioning mandrel 5 abut against the side of the lower plate 4 away from the upper plate 3, and then moves the lower plate 4 to make it close to the upper plate 3. During the movement, multiple positioning mandrels 5 are respectively slidably connected with each upper positioning hole, which plays a limiting role in the movement trajectory of the lower plate 4, so that the lower plate 4 can be well matched with the upper plate 3. Then the operator passes the bolt 6 through the positioning mandrel 5 and the gasket 2 in turn, and makes the bolt 6 threadedly connected with the nut 1 to achieve the pressing of the upper plate 3 and the lower plate 4, which is conducive to improving the bonding stability.

[0032] The positioning core shaft 5 includes an abutment portion 53, a coarse connection portion 51, and a fine connection portion 52. The abutment portion 53 is located on one side of the lower plate 4 and abuts against the lower plate 4. The abutment portion 53 is arranged corresponding to the gasket 2, and cooperates to apply pressure to press the upper plate 3 and the lower plate 4, so that the bonding between the two layers of plate is tighter.

[0033] The outer diameter of the abutment portion 53 is larger than the outer diameter of the thick connection portion 51, and the outer diameter of the thick connection portion 51 is larger than the outer diameter of the thin connection portion 52. The thick connection portion 51 is used to connect with the lower positioning hole, and the thin connection portion 52 is used to connect with the upper positioning hole. The thick connection portion 51 is adapted to the lower positioning hole, and the thin connection portion 52 is adapted to the upper positioning hole. The length of the thick connection portion 51 is smaller than the depth of the lower positioning hole.

[0034] In the embodiment of the utility model, the diameter of the thick connecting part 51 is 42 mm, and the diameter of the thin connecting part 52 is 40 mm; the length of the thin connecting part 52 is 16 mm, the thickness of the upper plate 3 is 18 mm, the length of the thick connecting part 51 is 12 mm, and the thickness of the lower plate 4 is 13 mm.

[0035] When the positioning core shaft 5 limits the relative position relationship between the upper plate 3 and the lower plate 4, the coarse connection part 51 is moved and placed in the lower positioning hole, and the fine connection part 52 is moved and placed in the upper positioning hole. The coarse connection part 51 is adapted to the lower positioning hole, and the fine connection part 52 is adapted to the upper positioning hole. Therefore, when the positioning core shaft 5 is working, the positioning effect of the upper plate 3 and the lower plate 4 is more precise, which is beneficial to reduce the bonding offset between the upper plate 3 and the lower plate 4.

[0036] A first chamfer 7 is provided at the connection position between the coarse connection portion 51 and the thin connection portion 52, and the first chamfer 7 is arranged along the circumference of the coarse connection portion 51. A second chamfer 8 is provided at a position of the thin connection portion 52 away from the coarse connection portion 51, and the second chamfer 8 is arranged along the circumference of the thin connection portion 52. The angle between the first chamfer 7 and the second chamfer 8 is 40°-80°. In the embodiment of the utility model, the angle between the first chamfer 7 and the second chamfer 8 is 60°.

[0037] When the thick connection part 51 moves into the lower positioning hole, the first chamfer 7 plays a guiding role, so that the thick connection part 51 can slide and connect with the lower positioning hole more smoothly. When the thin connection part 52 moves into the upper positioning hole, the second chamfer 8 plays a guiding role, so that the thin connection part 52 can slide and connect with the upper positioning hole more smoothly.

[0038] The implementation principle of the interlayer bonding positioning device of a protective composite panel in an embodiment of the utility model is as follows: when using the positioning mandrel 5, the operator inserts the four positioning mandrels 5 into the four lower positioning holes of the lower plate 4 from bottom to top respectively; then aligns the position of the upper plate 3 and the lower positioning hole, at this time, the position of the upper positioning hole is roughly aligned with the position of the lower positioning hole, and the operator then moves the lower plate 4 to make it close to the upper plate 3, and passes the four positioning mandrels 5 through the upper positioning holes from bottom to top respectively; finally, the bolts 6, gaskets 2, and nuts 1 are installed on the positioning mandrels 5 from bottom to top, thereby achieving the effect of tightening the bolts 6 and clamping the composite panel.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
