Description
Technical Field
[0001] The invention relates to the technical field of surge protectors of lightning protection products, in particular to a welding tool for surge protectors. Background Art
[0002] like Figure 1 The picture shows a surge protector, one of the company's self-developed lightning protection products. The surge protector is used to protect equipment and systems from high voltage and high current shocks, so product quality is particularly important.
[0003] After potting, the surge protector needs to manually solder a connecting piece. During welding, the worker holds the connecting piece for welding. Because the welding method is overlap welding, the hands must not shake during welding, otherwise there will be false welding, affecting the product quality. At the same time, the connection piece must be aligned with the second welding point during welding. After welding the first welding point, there is often a gap between the connecting piece and the second welding point when welding the second welding point. During welding, the connecting piece must be pressed to make it contact with the second welding point. The pressing force is uncontrollable, and the connecting piece is easily pressed and deformed, affecting the appearance of the product; in addition, the welding process will generate heat and cause hot hands. If you let go at this time, it will cause false welding problems. Summary of the invention
[0004] In view of the above-mentioned shortcomings and deficiencies, the present invention provides a surge protector welding tool to improve welding quality and welding efficiency, meet product quality requirements, and ensure product safety and reliability.
[0005] In order to achieve the above-mentioned purpose, the main technical solution adopted by the present invention is a surge protector welding tool, which includes a positioning unit and a crimping unit. The crimping unit is rotatably connected to the positioning unit above the positioning unit, and the surge protector is fixed in the positioning unit. The connecting piece and the welding point to be welded are fixed by adjusting the rotation angle of the crimping unit.
[0006] The positioning unit is a concave structure, and a mounting groove adapted to the surge protector housing is provided inside the positioning unit. A positioning groove is provided on one side of the mounting groove. The surge protector is slidably connected to the positioning groove and fixed inside the mounting groove.
[0007] The crimping unit includes a horizontal adjustment unit and a vertical adjustment unit. The horizontal adjustment unit is rotatably connected to the positioning unit, and the vertical adjustment unit is slidably connected to the horizontal adjustment unit. The end of the vertical adjustment unit is crimped on the connecting piece, and the position of the crimped connecting piece is adjusted by the cooperation between the horizontal adjustment unit and the vertical adjustment unit.
[0008] The horizontal adjustment unit includes a rotating column and a rotating shaft. The rotating shaft is fixedly arranged at the lower end of the rotating column. A rotating neck is arranged below the rotating shaft. The rotating neck is inside the positioning unit. The entire horizontal adjustment unit can be horizontally rotated by cooperating with the rotating neck through a positioning pin arranged outside the positioning unit. A fastening nail is arranged at the upper end of the rotating column.
[0009] The vertical adjustment unit includes a crossbeam, a crimping rod and a lifting button. The crossbeam is slidably connected to the rotating column of the horizontal adjustment unit and is fixed in position by the fastening pins of the horizontal adjustment unit. A spring is sleeved on the crimping rod, and the upper end of the crimping rod extends from the upper end of the crossbeam and is fixedly connected to the lifting button.
[0010] The crimping rod is slidably connected to the cross beam through a crimping rod positioning hole arranged at the end of the cross beam. A baffle is arranged on the crimping rod, and the diameter of the baffle is larger than the diameter of the crimping rod positioning hole.
[0011] The present invention has the following beneficial effects and advantages: The present invention is a welding tool for a surge protector, which can be used to weld two welding points of a connecting piece of a filled surge protector. A positioning unit and a crimping unit are designed according to the requirements that the crimping force is not allowed to cause deformation of the connecting piece and that unstable handholding during welding can easily cause false welding. The surge protector is fixed by the positioning unit, the horizontal position of the crimping unit is adjusted by the horizontal adjustment unit, and the vertical position of the crimping unit is adjusted by the vertical adjustment unit. The setting of the spring will not cause the phenomenon of deformation of the connecting piece due to excessive pressing force. The tool is easy to operate, and the welding process of the connecting piece can be realized as required, thereby ensuring the appearance and quality of welded products and improving production efficiency.
