Description

Technical Field

[0001] This invention relates to the field of antenna technology, and in particular to an antenna frame connection device. Background Technology

[0002] In the existing technology, antenna frames are generally assembled by welding square tubes. The frame contains an integrally formed connector. During assembly, the connectors are mated together. The integrally formed connector has a guide cylindrical pin, and another connector connected to it has a positioning hole. The positioning and connection between products can be achieved through the integrally formed connector. Therefore, the pin and hole are integrally machined on the connector.

[0003] Its drawback is its lack of flexibility. This one-piece machined connector has a built-in guide cylindrical pin, and the other connector it connects to has a built-in positioning hole. The guide pin and positioning hole allow for coarse positioning of the entire antenna frame product. However, the adjustable range after the two connectors are connected is small, depending solely on the fit accuracy between the connector guide pin and the positioning hole. If, after the two connectors are assembled, there is a deviation of 1mm or more in either direction (horizontal or vertical), adjustment cannot be made using this type of connector. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a positioning connection device and its manufacturing and connection method for adjusting the position accuracy of an antenna frame, which solves the problem that the existing technology cannot adjust the antenna frame due to large deviations after the two connectors are connected.

[0005] The objective of this invention is achieved as follows: A positioning connection device for adjusting the positional accuracy of an antenna frame includes a male connector and a female connector. The male connector has multiple first main positioning holes and multiple main screw holes on one side where it mates with the female connector. A positioning plate is provided on this side. The positioning plate has multiple first secondary positioning holes and secondary screw holes corresponding to the first main positioning holes and main screw holes. The positioning plate is connected to the side of the male connector by multiple first positioning pins and multiple screws. A second positioning pin is provided on the outer surface of the positioning plate. A second positioning hole that mates with the second positioning pin is provided on the side of the female connector where it mates with the male connector.

[0006] As a preferred embodiment of the positioning and connecting device of the present invention, the top surface of the male connector is provided with a third positioning hole, and a third screw hole is provided around the third positioning hole. The top surface of the female connector is provided with a fourth positioning hole, and a fourth screw hole is provided around the fourth positioning hole. The top surfaces of the male connector and the female connector are connected by a connecting plate. The bottom of the connecting plate is provided with a third positioning pin corresponding to the third positioning hole and a fourth positioning pin corresponding to the fourth positioning hole. The connecting plate is also provided with a fifth screw hole corresponding to the third screw hole and the fourth screw hole.

[0007] A method for manufacturing and connecting a positioning and connecting device includes the following steps:

[0008] Step 1) Connector fabrication: Male and female connectors are machined in one step on a CNC machine tool;

[0009] Step 2) Positioning plate fabrication: A positioning plate with a second positioning pin is fabricated in one machining operation on a CNC machine tool.

[0010] Step 3) Rough positioning of the positioning plate: Wrap the second positioning pin with tape and connect it to the female connector. Insert the second positioning pin into the second positioning hole of the female connector. Use the positioning clamp to adjust the angle of the positioning plate to obtain the rough positioning dimension data.

[0011] Step 4) Positioning plate installation: According to the rough positioning dimension data, place the positioning plate on the male connector at the position to be fixed, adjust the position and then fix it. Specifically, after adjusting the position, open multiple corresponding first main positioning holes and first secondary positioning holes in the middle position of the positioning plate and on the surface of the connector, insert the first positioning pin, and complete the rough positioning of both.

[0012] Step 5) Positioning the positioning plate precisely. After aligning the male and female connectors, perform an overall remeasurement. If the measurement data still shows a deviation, remove the positioning pins. After fine-tuning the special positioning parts according to the measurement data, enlarge the first main positioning hole and the first secondary positioning hole. Then reinstall the first positioning pin with the corresponding enlarged size and perform another remeasurement. If the measurement data still shows a deviation, continue the above operations and further enlarge the first positioning pin. If the measurement data shows no deviation, open the corresponding main screw holes and secondary screw holes at the four corners of the positioning plate and the connector, screw in the screws to complete the fixation, and then align the male and female connectors.

[0013] Step 6) Fixing the connecting plate: Insert the connecting plate into the top surface of the male and female connectors, and use screws to fix the connecting plate to the top surface of the male and female connectors.

[0014] As a preferred embodiment of the connection manufacturing method described in this invention, adjusting the position in step 4) specifically involves:

[0015] Step 3-1) Place the positioning plate on the male connector at the position to be fixed according to the rough positioning dimension data;

[0016] Step 3-2) Mark the connection between the positioning plate and the male connector;

[0017] Step 3-3) Remove the positioning plate, apply quick-drying adhesive to its inner surface, then attach the male connector to the positioning plate, and complete the initial fixing of the positioning plate according to the markings.

[0018] As a preferred technical solution of the connection manufacturing method described in this invention, the male connector and the positioning plate are fixed to a boss on the surface, and the positioning plate is fixed to the boss.

[0019] As a preferred technical solution of the manufacturing connection method described in this invention, the thickness of the positioning plate can be adjusted according to the deviation of the actual product. The thickness of the positioning plate must be sufficient to reach the depth of the countersunk screw recess. If the thickness of the positioning plate does not reach the depth of the countersunk screw recess, the positioning pin hole and screw hole need to be locally thickened, and the second positioning hole and screw connection hole are machined during machining.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] Through the improvements of this invention, the assembled antenna frame can be offset in any direction (horizontal or vertical) without being disassembled, thereby achieving the required dimensional accuracy between the upper and lower parts of the antenna frame. Existing products use an integrated structure with a guide cylindrical pin, which is large and difficult to carry. To achieve its guiding function, collisions with the protruding guide cylindrical pin must be avoided during transportation and use. This invention, however, has a simple structure, is lightweight, and easy to carry, solving the collision problem caused by the large size of the parts. Furthermore, during installation, this invention can be appropriately adjusted according to the required dimensional accuracy of the product to achieve the desired precision.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1

[0035] like Figure 1-6 The positioning connection device shown includes a male connector 100 and a female connector 200. The side of the male connector 100 that mates with the female connector 200 has a plurality of first main positioning holes 101 and a plurality of main screw holes 102. The side is provided with a positioning plate 400. The positioning plate 400 has a plurality of first secondary positioning holes 401 and secondary screw holes 402 corresponding to the first main positioning holes 101 and the main screw holes 102. The positioning plate 400 is connected to the side of the male connector 100 by a plurality of first positioning pins 600 and a plurality of screws 700. The outer surface of the positioning plate 400 is provided with a second positioning pin 403. The side of the female connector 200 that mates with the male connector 100 has a second positioning hole 201 that mates with the second positioning pin 403.

[0036] Specifically, the male connector 100 and the female connector 200 are respectively machined with a first boss 103 and a second boss 202 on the side where they meet. The first boss 103, the second boss 202, and the positioning plate 400 are all square structures. The positioning plate 400 is installed on the first boss 103, and the second positioning hole 201 is opened on the second boss 202. The second positioning pin 403 is placed in the middle of the positioning plate 400, and the first auxiliary positioning hole 401 surrounds the second positioning pin 403. There are four main screw holes 102 and four auxiliary screw holes 402, which are located at the four corners of the first boss 103 and the positioning plate 400. The end of the second positioning pin 403 is machined into a spherical head.

[0037] It should be noted that the design of the first protrusion 103 and the second protrusion 202 facilitates the installation of the positioning plate 400. At the same time, the square design facilitates data calculation during installation, especially the distance between the installation position and the plane. Since the antenna frame is mainly constructed by welding and assembling square tubes 300, the square male connector 100 and female connector 200 facilitate installation and also facilitate the installation with the first protrusion 103, the second protrusion 202, and the positioning plate 400.

[0038] As a preferred technical solution of the positioning and connecting device of the present invention, the top surface of the male connector 100 is provided with a third positioning hole 104, and a third screw hole 700 105 is provided around the third positioning hole 104. The top surface of the female connector 200 is provided with a fourth positioning hole 203, and a fourth screw hole 700 204 is provided around the fourth positioning hole 203. The top surfaces of the male connector 100 and the female connector 200 are connected by a connecting plate 500. The bottom of the connecting plate 500 is provided with a third positioning pin 501 corresponding to the third positioning hole 104 and a fourth positioning pin 502 corresponding to the fourth positioning hole 203. The connecting plate 500 is also provided with a fifth screw hole 503 corresponding to the third screw hole 700 105 and the fourth screw hole 700 204.

[0039] Specifically, there are four of each of the third screw 700 hole 105 and the fourth screw 700 hole 204, distributed around the outer periphery of the third positioning hole 104 and the fourth positioning hole 203. The bottom of the third positioning pin 501 and the fourth positioning pin 502 are machined into spherical heads for easy insertion.

[0040] Example 2

[0041] A method for manufacturing and connecting a positioning and connecting device includes the following steps:

[0042] Step 1) Connector fabrication: Male connector 100 and female connector 200 are machined in one step on a CNC machine tool according to preset data.

[0043] Step 2) Fabrication of positioning plate 400: The positioning plate 400 with the second positioning pin 403 is fabricated in one machining operation on a CNC machine tool according to the preset data.

[0044] Step 3) Coarse positioning of the positioning plate 400. As Figure 7 shown, wind masking tape around the second positioning pin 403 and connect it to the female joint 200. Insert the second positioning pin 403 into the second positioning hole 201 of the female joint 200. Use the positioning card plate 800 to adjust the angle of the positioning plate 400 to obtain the coarse positioning dimension data. The purpose of winding the masking tape is to eliminate the gap to improve the accuracy during its insertion and eliminate the influence of the gap on data measurement. The positioning card plate 800 has a "冂"-shaped structure with three sides flush and the two sides perpendicular to the middle side. When in use, first insert the positioning plate 400 into the female joint 200, then make the middle side of the positioning card plate 800 fit with one side of the positioning plate 400, and adjust the positioning card plate 800 to make its two sides parallel to the top surface of the female joint 200. This can greatly improve the measurement accuracy and provide a basis for the high-precision positioning of the positioning plate 400 on the male joint 100 later.

[0045] Step 4) Installation of the positioning plate 400. As Figure 8 shown, place the positioning plate 400 at the position to be fixed on the male joint 100 according to the coarse positioning dimension data. After adjusting the position, fix it. Specifically: After adjusting the position, open a plurality of corresponding first main positioning holes 101 and first auxiliary positioning holes 401 at the middle position of the positioning plate 400 and the joint surface, and insert the first positioning pin 600 to complete the coarse positioning of the two. The coarse positioning data mainly includes the horizontal and vertical distances between the positioning plate 400 and the female joint 200. After positioning, use a drill bit to open a through hole and insert the first positioning pin 600. The three-point design can ensure stability.

[0046] Step 5) Fine positioning of the positioning plate 400. After docking the male joint 100 and the female joint 200, conduct an overall remeasurement. If the measurement data shows that there is still a deviation, remove the positioning pin, fine-tune the special positioning part according to the measurement data, then perform an enlarging treatment on the first main positioning hole 101 and the first auxiliary positioning hole 401, and install the first positioning pin 600 corresponding to the enlarged hole size again. Then conduct a remeasurement again. If the measurement data still shows a deviation, the above operations can be continued and the first positioning pin 600 can be further enlarged. If the measurement data shows no deviation, then open corresponding main screw holes 102 and auxiliary screw holes 402 for the screws 700 at the four corners of the positioning plate 400 and the joint, screw in the screws 700 to complete the fixation, and then dock the male joint 100 and the female joint 200. At this time, the top surface and the side surface of the male joint 100 and the female joint 200 are flush. During the remeasurement, mainly measure the horizontal and vertical distances between the positioning plate 400 and the male joint 100. This step can further improve the accuracy.

[0047] Step 6) Fixing the connecting plate 500: Insert the connecting plate 500 into the top surface of the male connector 100 and the female connector 200, and use screws 700 to fix the connecting plate 500 to the top surface of the male connector 100 and the female connector 200.

[0048] Furthermore, in step 4), adjusting the position specifically involves:

[0049] Step 3-1) Place the positioning plate 400 on the male connector 100 at the position to be fixed according to the rough positioning dimension data;

[0050] Step 3-2) Mark the connection point between the positioning plate 400 and the male connector 100;

[0051] Step 3-3) Remove the positioning plate 400, apply quick-drying adhesive to its inner surface, then attach the male connector 100 to the positioning plate 400, and complete the initial fixation of the positioning plate 400 according to the markings.

[0052] The above method facilitates the opening of the first main positioning hole 101 and the first secondary positioning hole 401, thus avoiding the influence of vibration during hole opening, which could lead to misalignment and affect accuracy.

[0053] Example 3

[0054] like Figure 9 As shown, the difference between this embodiment 3 and embodiment 2 is that the positioning plate 400 is thinner, and it is thickened locally on the inner side of the positioning plate 400, as shown in the figure; the positioning plate 400 is thinner, making it inconvenient to make holes, so it is achieved by thickening the inner side of the positioning plate 400.

[0055] The above description of the embodiments is only for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make several improvements and modifications to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
