Abstract
Description
Technical Field
[0001] The present invention relates to a method for fixing components, and particularly to a method for increasing the depth of screw holes on a thin plate. Background Art
[0002] When fixing other components with screws on a thin plate such as an aluminum plate or an aluminum alloy thin plate, the screw holes must have sufficient depth to ensure the strength of the screw fixation. Generally, the depth of the screw hole should be at least twice the diameter of the screw. For example, for an M4 screw, the screw hole depth usually needs to be 8 mm. When the thickness of the thin plate is less than twice the diameter of the screw and other components need to be fixed to the thin plate with screws, in the prior art, generally, the local thickness of the thin plate is increased to increase the depth of the screw hole. This will cause two problems. One is that the process is too complex and the cost is relatively high; the other is that it is difficult to ensure sealing, which increases the difficulty especially for scenarios with sealing requirements. There is also a method of thickening the position of the preset screw hole on the thin plate and integrally forming it with the thin plate. This method has complex molds and processes, high costs, and poor assembly flexibility. Summary of the Invention
[0003] The technical problem to be solved by the present invention is to propose a method, structure and wireless communication base station for increasing the depth of screw holes on a thin plate with simple process and ensuring sealing performance in view of the above-mentioned defects of the prior art.
[0004] The technical solution adopted by the present invention to solve its technical problems is as follows:
[0005] Provide a method for increasing the depth of screw holes on a thin plate. Based on the thin plate being an aluminum plate or an aluminum alloy plate, it includes the following steps:
[0006] ➀ Select a base member harder than the material of the thin plate. The base member includes a first end and a second end, and the second end is closed and narrowed. The depth of the screw hole is greater than the thickness of the thin plate;
[0007] ➁ Use a press to press the second end of the base member into the position of the preset screw hole on the thin plate;
[0008] ➂ The second end of the base member extrudes the aluminum material or aluminum alloy material inside the thin plate outwards to form a convex bulge; control the stroke and pressure of the press to ensure that the second end of the base member does not break through the convex bulge. Before or after the base member is pressed into the thin plate, a screw hole is provided at the first end of the base member.
[0009] Further:
[0010] The press is a pneumatic press, a hydraulic press or a mechanical transmission press.
[0011] Design a structure for increasing the depth of a screw hole on a thin plate, where the thin plate is an aluminum plate or an aluminum alloy plate, including: a base member, the first end of which is provided with a screw hole, and the second end is closed and narrowed. The depth of the screw hole is greater than the thickness of the thin plate, and the hardness of the base member is higher than that of the thin plate material; a convex hull, which is formed by pressing the second end of the base member into a set position of the thin plate from one side of the thin plate by a press and extruding the aluminum or aluminum alloy material inside the thin plate to the other side of the thin plate. The convex hull is closed; the base member is embedded in the convex hull.
[0012] Design a wireless communication base station, including a heat dissipation plate on the outer layer, and a structure for increasing the depth of a screw hole is provided on the heat dissipation plate. The structure for increasing the depth of the screw hole includes: a base member, the first end of which is provided with a screw hole, and the second end is closed and narrowed. The depth of the screw hole is greater than the thickness of the heat dissipation plate, and the hardness of the base member is higher than that of the thin plate material; a convex hull, which is formed by pressing the second end of the base member into a set position of the heat dissipation plate from one side of the heat dissipation plate by a press and extruding the aluminum or aluminum alloy material inside the heat dissipation plate to the other side of the heat dissipation plate. The convex hull is closed; the base member is embedded in the convex hull.
[0013] The second end of the base member gradually narrows into a cone.
[0014] In the present invention, since the second end of the base member pushes out the aluminum and aluminum alloy materials inside the thin plate to form a protrusion, the thickness of the preset screw hole position of the thin plate is increased, and the base member with a screw hole depth greater than the thickness of the thin plate can be accommodated. At the same time, by controlling the pressure and stroke of the press, it can be ensured that the base member will not break through the convex hull. In this way, the problem of inability to seal due to drilling holes in the thin plate can be avoided. Compared with the prior art, in the preset screw hole position, only by pressing the base member into the specified position with a press and controlling the pressure and stroke, the depth of the threaded hole can be increased and the sealing and flexibility of component assembly can be ensured. The process and operation are simple. Description of the Drawings

[0021] Now, in conjunction with the accompanying drawings, detailed descriptions of the preferred embodiments of the present invention will be given.
[0022] A method and structure for increasing the depth of a screw hole on a thin plate, as Figures 1 to 3 shown, based on the thin plate 10 being an aluminum plate or an aluminum alloy plate, includes the following steps:
[0023] 1. Select a base member 20 with a hardness higher than that of the thin plate material. The first end of the base member is provided with a screw hole 21, and the second end 22 is closed and narrowed. The depth of the screw hole 22 is greater than the depth of the thin plate 10;
[0024] 2. Use a press to press the second end 22 of the base member 20 into the position of the preset screw hole of the thin plate 10;
[0025] 3. The second end 22 of the base member 20 extrudes the aluminum material and aluminum alloy material inside the thin plate outwards to form a convex bulge 11. Control the stroke and pressure of the press to ensure that the second end 22 of the base member 20 does not pierce through the convex bulge 11. The screw hole 21 of the base member is set before or after the base member is pressed into the thin plate.
[0026] The above-mentioned press can be a pneumatic press, a hydraulic press or a mechanical transmission press. In order to facilitate the extrusion of the aluminum material and aluminum alloy material inside the thin plate, the second end of the base member is gradually narrowed into a conical shape.
[0027] When the component to be fixed is fixed to the thin plate, pass a screw through the connection part of the component to be fixed and then screw it into the threaded hole of the base member of the thin plate and tighten it to complete the fixation. Since the second end of the base member pushes the aluminum material and aluminum alloy material inside the thin plate outwards to form a protrusion, the thickness of the preset screw hole position of the thin plate is increased, and a base member with a screw hole depth greater than the thickness of the thin plate can be accommodated. At the same time, by controlling the pressure and stroke of the press, it can be ensured that the base member does not pierce through the convex bulge. In this way, the problem of inability to seal due to drilling holes in the thin plate can be avoided. Compared with the prior art, at the preset screw hole position, only need to press the base member into the specified position with a press, control the pressure and stroke, then the depth of the threaded hole can be increased, and the sealing and the flexibility of component assembly can be ensured. The process and operation are simple.
[0028] The method of the present invention can be used in wireless communication base stations.
[0029] Such as Figures 4 to 6As shown, a wireless communication base station 100 includes an outer thin plate 10, which is a heat dissipation plate. Heat dissipation teeth extend on the heat dissipation plate. A structure for increasing the depth of the screw hole is provided on the heat dissipation plate 10. The structure for increasing the depth of the screw hole includes:
[0030] A base member 20, with a screw hole 21 provided at the first end of the base member 20 and the second end 22 being closed and narrowed. The depth of the screw hole 21 is greater than the thickness of the heat dissipation plate 10, and the hardness of the base member 20 is higher than the hardness of the thin plate material;
[0031] A convex hull 11, which is formed by pressing the second end of the base member into a set position on the heat dissipation plate from one side of the thin plate by a press, and extruding the aluminum material or aluminum alloy material inside the heat dissipation plate 11 to the other side of the heat dissipation plate 10. The convex hull 11 is closed;
[0032] The base member 20 is embedded in the convex hull 11, and the first end 21 of the base member 20 can be flush with the surface of the heat dissipation plate. When the component 40 to be fixed needs to be fixed to the heat dissipation plate, a screw 30 is passed through the connection part of the component 40 to be fixed and then screwed into the threaded hole 21 of the base member in the heat dissipation plate and tightened to complete the fixation.
[0033] To improve the heat dissipation effect, the heat dissipation plate of the wireless communication base station is usually the thinner the better. If the heat dissipation plate is thick, it will not only affect the heat dissipation effect, but also increase the product weight and cost. However, if other components need to be fixed by screws on a very thin heat dissipation plate made of aluminum alloy or aluminum plate, the aluminum alloy or aluminum plate does not have enough thickness, which is not feasible. Moreover, when using screws to fix other components, the sealing performance of the heat dissipation plate also needs to be ensured. Therefore, the method of the present invention can exactly meet the requirement of fixing other components on the heat dissipation plate of the wireless communication base station. Compared with the prior art of locally thickening the heat dissipation plate, the method of the present invention has low process requirements, is easy to operate, and reduces the cost.
[0034] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. For those skilled in the art, the technical solutions described in the above embodiments can be modified, or some of the technical features can be equivalently replaced; and these modifications and replacements should all fall within the protection scope of the appended claims of the present invention.
