Detailed Implementation

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, a titanium alloy selective welding fixture includes a positioning component 100 and a straightening component 200. The positioning component 100 includes a base plate 101 and a solder baffle frame 107. The base plate 101 is provided with a mounting groove 102. A support plate 103 is fixedly connected to the inner side wall of the mounting groove 102. A positioning plate 104 is placed inside the mounting groove 102. The bottom of the positioning plate 104 contacts the top of the support plate 103.

[0029] like Figure 2 and Figure 3 As shown, the solder blocking frame 107 is fixed around the edge of the base plate 101 to effectively intercept the flow of solder. Both sides of the top of the solder blocking frame 107 are provided with locking seats 108. The cooperation between the locking seats 108 and the locking buckle 204 facilitates the installation and locking of the straightening component 200.

[0030] like Figure 3 As shown, the positioning plate 104 includes a plate body 1041. The plate body 1041 has a plurality of positioning grooves 1042 along its length direction, which can accommodate multiple workpieces for batch welding at the same time, thereby improving production efficiency. The positioning grooves 1042 are provided with hollow grooves 1043, which on the one hand reduces the overall weight of the positioning plate 104 and facilitates operation; on the other hand, it facilitates the avoidance of components on the PCB board.

[0031] like Figure 1 and Figure 2As shown, pressure grooves 1044 are provided on both sides of the plate 1041, and pressure blocks 105 are rotatably connected to both sides of the top of the base plate 101. One side of the bottom of the pressure block 105 abuts against the inner bottom wall of the pressure groove 1044. Limiting blocks 106 are fixedly connected to the four corners of the top of the base plate 101. The limiting blocks 106 are distributed at the four corners of the mounting groove 102. When the positioning plate 104 is placed into the mounting groove 102, the four limiting blocks 106 limit the corners of the positioning plate 104. Rotating the pressure block 105 can press the pressure block 105 firmly onto the inner bottom wall of the pressure groove 1044, ensuring the stability of the positioning plate 104 and the workpiece during the welding process.

[0032] like Figure 2 and Figure 3 As shown, support rods 110 are fixedly connected to the left and right sides of the solder shield 107. The support rods 110 provide convenient gripping points for picking up and putting down the fixture. Operators can easily move the fixture through the support rods 110, reducing the risk of burns caused by direct contact with high-temperature areas, and improving the compatibility of the fixture in automated production lines.

[0033] like Figure 1 and Figure 5 As shown, the straightening assembly 200 includes a cover plate 201. A limiting plate 202 is fixedly connected to the bottom of the cover plate 201 via an elastic element. The elastic element automatically adjusts the downward pressure of the limiting plate 202 according to the height difference of the workpieces, ensuring that each workpiece receives uniform and moderate pressure, thus avoiding welding quality problems caused by uneven pressure. The bottom of the limiting plate 202 abuts against the top of the positioning plate 104. Bases 203 are fixedly connected to both sides of the cover plate 201. A latch 204 is rotatably connected within the base 203. The output end of the latch 204 engages in the locking groove of the locking seat 108. The latching engagement between the latch 204 and the locking seat 108 enables rapid locking and releasing of the straightening assembly 200, simplifying the operation process and improving production efficiency.

[0034] like Figure 1 and Figure 5 As shown, the limiting plate 202 has multiple limiting grooves along its length, which correspond to the positioning groove 1042. The top of the inner wall of the limiting groove has multiple limiting protrusions, the top of which is flush with the top of the limiting plate 202, which realizes precise positioning and fixing of the workpiece and effectively prevents the workpiece from shifting during the welding process.

[0035] like Figure 1 and Figure 5As shown, multiple positioning seats 109 are fixedly connected to the top of the base plate 101, and multiple positioning rods 205 are fixedly connected to the bottom of the cover plate 201. The positioning rods 205 are movably inserted into the positioning seats 109, ensuring that the cover plate 201 can be accurately aligned with the base plate 101 during the closing process, thus avoiding the risk of misalignment between the limiting plate 202 and the positioning plate 104 caused by the offset of the cover plate 201.

[0036] like Figure 1 and Figure 5 As shown, the cover plate 201 is equipped with an observation window. This window provides operators with an intuitive view for monitoring the welding process. Through the observation window, operators can view the formation of solder joints, the flow of solder, and the positioning stability of the workpiece in real time, promptly identifying and addressing any abnormalities that occur during the welding process, such as solder overflow or workpiece displacement. This design not only improves welding quality but also reduces rework rates due to quality issues, thereby lowering production costs.

[0037] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
