DETAILED DESCRIPTION

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Please see Figures 1-7 This utility model provides a technical solution: an adjustable mating interface radio frequency connector welding device, including welding electrodes 1, base 2, lifting platform 4, screw 5, drive mechanism 9 and leveling mechanism 10. A platform is raised in the middle of the base 2, and guide columns 3 are installed on the left and right sides of the platform. A limiting platform 7 is provided on the top of the guide columns 3. The lifting platform 4 is between the base 2 and the limiting platform 7, and the left and right ends are passed through by the guide columns 3. The bottom of the screw 4 is connected to the lifting platform 4, passes through the limiting platform 7 and drive mechanism 9 from bottom to top, and is connected to the leveling mechanism 10 at the top. The welding electrodes 1 are installed on the left and right sides outside the platform of the base 2.

[0031] like Figures 5-6 As shown, the drive mechanism 9 includes a turntable 92, a drive rod 90, and second screws 91. The drive rod 90 is evenly fixed to the circumference of the turntable 92 by the second screws 91. When the welding support height needs to be adjusted, the turntable 92 is rotated by the drive rod 90, which in turn drives the lifting platform 4 to move up and down to achieve the optimal welding support height.

[0032] like Figures 3-4 As shown, the leveling mechanism 10 includes an adjustment platform 100, an elastic retaining ring 101, a rubber pad 102, and a screw sleeve 103. The upper surface of the adjustment platform 100 has two protruding structures: one side has a threaded end protrusion 105, and the opposite side has a smooth end protrusion 104. The screw sleeve 103 is movably secured to the smooth end protrusion 104 on one side of the adjustment platform 100 via the elastic retaining ring 101. The screw sleeve 103 is used to connect with the female end of the connector being welded, ensuring a tight fit between the insulator end face and the center socket of the female connector and the upper surface of the smooth end protrusion 104. This prevents the insulator from expanding due to welding overheating and the socket from shifting. During welding, the insulator expands out; by tightening the screw sleeve 103, the insulator can be returned to its original position, thereby adjusting the mating interface dimensions of the connector.

[0033] The threaded end protrusion 105 has a recess 106 at its top for limiting the outer conductor and insulating sleeve in the male connector being soldered. A φ0.94mm blind hole 107 is located at the center of the recess 106 for limiting the protruding pin in the male connector being soldered. This ensures a tight fit between the insulator end face and the center pin in the male connector being soldered and the recess at the top of the threaded end protrusion, preventing the insulator from expanding due to overheating during soldering and preventing pin displacement.

[0034] like Figure 2 As shown, the bottom of the screw 5 is provided with a flange 50, and the flange 50 is provided with multiple screw mounting holes. From bottom to top, there are lifting adjustment threads 51, a square structure 52 and a smooth column structure 53. The top of the smooth column structure 53 is provided with two different specifications of welding positioning holes: φ0.94mm welding positioning hole 55 and φ1.3mm welding positioning hole 54.

[0035] The lifting platform 4 is movably mounted on the guide column 3 via a screw 5, and the lifting platform 4 and the screw 5 are connected and fixed by a first screw 6. This allows the lifting platform 4 to move up and down along with the screw 5 while being fixed in place when the drive mechanism 9 is manually adjusted.

[0036] The drive mechanism 9 and the screw 5 are connected by a threaded fit, while the limit platform 7 and the upper lifting thread section of the screw 5 are connected by a clearance fit. The outer diameter of the thread is smaller than the minimum inner diameter of the through hole in the middle of the limit platform, so that no frictional resistance is generated during the adjustment process.

[0037] The leveling mechanism 10 is positioned at the square structure 52 on the screw 5. This fixes the leveling mechanism 10 in the horizontal direction.

[0038] like Figure 7 As shown, the limiting platform 7 has light holes 71 at both ends on the left and right sides, and a hollow tubular shape protruding upward in the middle, with reinforcing ribs 70 at both ends of the protruding part.

[0039] The guide post 3 has a radius larger than the radius of the aperture 71 of the limiting platform 7, and a top radius smaller than the radius of the aperture 71, and is threaded. The threaded part of the guide post 3 passes through the aperture 71 and is connected to and fixed to the limiting platform 7 by a hexagonal nut 8.

[0040] Working principle: When using this RF connector soldering device, such as Figures 1-7As shown, a leveling mechanism matching the dimensions of the connector product to be processed is fitted into the square structure 52 of the bolt 5; on the leveling mechanism 10, the threaded sleeve 103 is connected to the female end to be welded, and the insulator end face and the center socket of the female connector are in contact with the upper end face of the raised structure 104 of the smooth rod end; the insulator end face of the male connector is in contact with the recess 106, and the center pin of the male connector is limited by the φ0.94mm blind hole 107; the top of the smooth column structure 53 is provided with welding positioning holes 55 and 54 of two different specifications, φ0.94mm and φ1.3mm, for limiting the center pin and the socket during welding; the rotary drive mechanism 9 adjusts the welding support height, thereby using the welding electrode 1 to perform welding operations, and the back interface size of the welding is controlled by adjusting the threaded sleeve 103 during welding.

[0041] This invention allows for the replacement of different sized leveling mechanisms to accommodate various RF connector models. During soldering, the interface dimensions after soldering can be controlled by adjusting the screw sleeve of the leveling mechanism. The leveling mechanism enables rapid positioning of the connector, improving production efficiency. The soldering height can be adjusted via the drive mechanism.

[0042] The above-disclosed embodiments are merely specific examples of this utility model. However, this utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
