The coaxial cable welding method adopts a floating type pressing mechanism to pre-tighten a pre-positioned target coaxial cable and a target structural member in the clamping space, and in the welding process, the clamping space is dynamically adjusted along with the state change of the coaxial cable and the target structural member so as to keep the pre-tightening force of the floating type pressing mechanism on the coaxial cable and the target structural member, ensure the stability of a welding point between the coaxial cable and the target structural member in the welding process and avoid crushing damage to a sheath of the coaxial cable.
In order to make the technical scheme of the invention easier to understand, the detailed implementation process of each step of the invention will be described in detail below.
S101, placing at least one target coaxial cable at a position to be welded on a target structural part;
the base station antenna is a key part covered by a mobile communication network, and most of main parts of the base station antenna are formed by simultaneously assembling and welding a plurality of coaxial cables and structural parts. The positioning procedure refers to that when the coaxial cable and the structural part need to be welded, the positions to be welded of the coaxial cable are placed at the corresponding positions to be welded on the structural part. After the coaxial cable and the structural member are positioned, the positional relationship between the coaxial cable and the structural member is maintained.
Referring to fig. 2 to 3, at least one circular arc groove 20 is disposed on the target structural member 2, and the circular arc groove 20 is used for accommodating the target coaxial cable 1.
S102, a target coaxial cable and a target structural part are pre-tightened by using a high-temperature-resistant floating type pressing mechanism, and the floating type pressing mechanism, the target coaxial cable and the target structural part form a welded whole;
after the target coaxial cable 1 and the target structural member 2 are positioned, the clamping process pre-tensions the coaxial cable 1 and the target structural member 2 to the clamping space 4 by using the floating type pressing mechanism 3. At this time, the floating pressing mechanism 3, the target coaxial cable 1 and the target structural member 2 together form a welded whole.
The floating type pressing mechanism 3 is adopted in the clamping process, and a certain pretightening force can be provided between the target coaxial cable 1 and the target structural member 2 before the welding process is carried out, so that the welding positions of the target coaxial cable 1 and the target structural member can be kept in good contact, and the uniformity of welding spot formation in the welding area during subsequent welding is improved.
Specifically, please refer to fig. 2 to fig. 3, two clamping arms 30 are disposed on the floating pressing mechanism 3, and the clamping arms 30 are used for pre-tightening the target coaxial cable 1 and the target structural member 2.
Further, the clamp arm 30 has an arc-shaped structure. The arc-shaped structure is smoother, and the area of the contact part of the arc-shaped structure and the target coaxial cable 1 is larger, so that the pre-tightening of the target coaxial cable 1 and the target structural member 2 is more reliable. Meanwhile, the floating type pressing mechanism 3 can pre-tighten a plurality of target coaxial cables 1 and a target structural part 2 simultaneously due to the arc-shaped structure.
Furthermore, the floating pressing mechanism 3 sleeves the at least one target coaxial cable 1 and the target structural member 2 between the clamping arms of the arc-shaped structure from bottom to top. The floating type pressing mechanism 3 can simultaneously pre-fasten a plurality of target coaxial cables and target structural members corresponding to the target coaxial cables in the clamping space 4 by utilizing the clamping arm 30 with the arc-shaped structure, so that the welding of the target coaxial cables is realized, and the production efficiency is improved.
S103, transferring the whole welding body to a welding position to perform a welding process;
after the floating pressing mechanism 3, the target coaxial cable 1 and the target structural member 2 together form a welding whole 100, a welding point between the target coaxial cable 1 and the target structural member 2 needs to be welded. The welding entity is transferred to a welding station for welding.
When the welding process is performed, the floating type pressing mechanism 3 adjusts the clamping space 4 according to the state change of the target coaxial cable 1 and the target structural member 2 so as to adaptively press the target coaxial cable 1 and the target structural member 2.
When the state of the target coaxial cable 1 and the target structural member 2 changes (the state change refers to the phenomena that the target coaxial cable 1 and the target structural member 2 deform due to welding or gaps are generated at a part of welding positions of the target coaxial cable 1 and the target structural member 2 due to welding, and the like; the state change can also be understood as the change of the contact condition of the welding positions between the target coaxial cable 1 and the target structural member 2) in the process of the welding procedure, the floating type pressing mechanism 3 correspondingly adjusts the clamping space to adaptively press the target coaxial cable 1 and the target structural member 2, namely, the floating fastening effect is achieved; the floating type pressing mechanism 3 can achieve the similar effect of correspondingly offsetting the stress correspondingly generated by welding the target coaxial cable 1 and the target structural member 2 while adjusting the clamping space 4, thereby playing a compensation role in the whole welding process on the deformation generated by welding the target coaxial cable 1 and the target structural member 2 and the gap generated by a part of welding positions, avoiding the condition of poor contact between the target coaxial cable 1 and the target structural member 2 caused by welding, correspondingly ensuring the uniformity and firmness of welding spots, and reducing the risk that the welding spots fall off in the subsequent use process of the target coaxial cable 1 and the target structural member 2.
Preferably, the floating type pressing mechanism 3 is made of 65 manganese steel. The 65 manganese steel has good hardenability and hardness, can effectively keep effective clamping on the target coaxial cable 1 and the target structural member 2 in the welding process of the target coaxial cable 1 and the target structural member 2, can effectively follow the heating expansion of the target coaxial cable 1 to adaptively adjust the clamping space of the 65 manganese steel, and avoids damage to the sheath of the coaxial cable. Meanwhile, the floating type pressing mechanism 3 can be prevented from being damaged in the high-temperature welding process, and the recycling of the floating type pressing mechanism 3 is facilitated.
Preferably, a part of the contact portion between the floating pressing mechanism 3 and the target coaxial cable 1 or the target structure 2 is made of 65 manganese steel, so that the clamping space can be dynamically adjusted when the state of the target coaxial cable 1 or the target structure 2 changes.
Alternatively, the floating pressing mechanism 3 may be made of stainless steel, and a part of the structure of the contact portion between the floating pressing mechanism 3 and the target coaxial cable 1 or the target structural member 2 may be made of stainless steel.
The floating pressing mechanism 3 can be made of stainless steel or the like for realizing the state adaptability dynamic adjustment of the clamping space 4 following the target coaxial cable 1 and the target structural member 2.
Meanwhile, corresponding elastic elements can be arranged at the contact parts of the floating type pressing mechanism 3 and the target coaxial cable 1 and the target structural member 2, and the elastic coefficients of the elastic elements are dynamically adjusted so as to dynamically adjust the clamping space when the states of the target coaxial cable 1 and the target structural member 2 are changed.
In the high-temperature welding process, due to the characteristics of expansion with heat and contraction with cold of the target coaxial cable 1 and the target structural member 2, when no tool is used for clamping the target coaxial cable 1 and the target structural member 2, or when the clamping tool is used for clamping but the clamping tool cannot change along with the dynamic change in the welding process of the target coaxial cable 1 and the target structural member 2, a gap between the target coaxial cable 1 and the target structural member 2 at a welding point can be changed, so that the welding of the target coaxial cable 1 and the target structural member 2 is influenced.
And the floating type pressing mechanism 3 correspondingly adjusts the clamping space 4 of the floating type pressing mechanism according to the welding temperature of the subsequent welding process, so that the clamping space 4 is ensured to dynamically change along with the radial expansion of the target coaxial cable 1 and the target structural member 2 generated at high temperature. The clamping space 4 is increased along with the increase of the welding temperature, and the damage of the sheath of the target coaxial cable 1 which expands along with the radial expansion of high temperature due to the unchanged clamping space is avoided while the pre-tightening of the target coaxial cable 1 and the target structural part 2 is kept.
The floating type pressing mechanism 3 can dynamically adjust the clamping space 4 to adaptively press the target coaxial cable 1 and the target structural member 2 during the high-temperature welding process, so as to control the gap between the target coaxial cable 1 and the target structural member 2 at the welding point to be within a reasonable range.
Specifically, the floating pressing mechanism 3 dynamically adjusts the clamping space 4 to adaptively control the gap between the target coaxial cable 1 and the target structural member 2 at the same welding point in the subsequent welding process within an adjustment range of 0-0.2 mm, so as to ensure effective welding between the target coaxial cable 1 and the target structural member 2.
Meanwhile, the coaxial cable belongs to a semi-rigid cable, in the high-temperature welding process, the target coaxial cable 1 can expand radially to generate acting force on the floating type pressing mechanism 3, the floating type pressing mechanism 3 can generate reaction force on the target coaxial cable 1, and the dynamic adaptability of the floating type pressing mechanism 3 enables the floating type pressing mechanism to adjust the state of the part of the target coaxial cable 1 in contact with the target coaxial cable in an adaptive manner, so that the damage of the sheath of the target coaxial cable 1 caused by the reaction force of the floating type pressing mechanism 3 is avoided.
Further, the clamping thickness of the clamping space 4 is increased by 0.15-0.25 mm for every 20 ℃ increase in the welding temperature relative to the predetermined welding temperature of the target coaxial cable 1. It can be understood that, due to the temperature rise, the expansion degree of the target coaxial cable 1 and the target structural member 2 changes, and the thickness of the clamping space 4 between the clamped target coaxial cable 1 and the clamped target structural member 2 also needs to be changed, so as to better pre-tighten the target coaxial cable 1 and the target structural member 2 and not damage the target coaxial cable 1. Wherein the clamping thickness is the distance from the contact point of the clamping space 4 and the target coaxial cable 1 to the contact surface of the clamping space 4 and the target structural member 1.
For example, assume that the optimum soldering temperature 200 ℃ of the target coaxial cable 1 is a predetermined soldering temperature. The clamping thickness of the clamping space 4 is 20mm at an optimum welding temperature of 200 ℃. In the welding process, the welding temperature is changed from 200 to 220, and the clamping space 4 is correspondingly increased by 0.15-0.25 mm. At this time, the size range of the clamping space 4 is 20.15-20.25 mm, for example, the clamping space 4 is correspondingly increased by 0.2mm on the original basis, and the clamping thickness of the clamping space 4 is 20.2 mm; when the temperature rises to 240 ℃, the clamping thickness of the floating type pressing mechanism is 20.4 mm.
In a preferred embodiment of the present invention, the floating pressing mechanism 3 is configured to maintain a distance of 0 to 0.2mm between a pressing position where the target coaxial cable 1 and the target structural member 2 are pressed and a welding position where the target coaxial cable 1 and the target structural member 2 are welded. Through a plurality of tests, the arranged compressing position can correspondingly provide the best pre-tightening effect for the welding position while not influencing welding, so that the welding quality is greatly improved, and meanwhile, the influence of welding on the compressing position bearing larger pressing force can be reduced by selecting the distance, so that the target coaxial cable 1 is ensured not to be damaged to the maximum extent.
S104, after welding is finished, the floating type pressing mechanism can be quickly detached from the target structural part, and welding of the coaxial cable and the target structural part is completed;
further, the air conditioner is provided with a fan,
after welding, the floating pressing mechanism 3 is moved out along one end of the target coaxial cable 1 along the axial direction of the target coaxial cable 1 to separate from the target structural member 2, so that the floating pressing mechanism 3 is recycled and reused.
The foregoing is only a partial embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
