Description

Technical Field

[0001] The utility model relates to the technical field of lightning protection product surge protectors, in particular to a surge protector welding tooling. Background Technique

[0002] As Figure 1 shown is a surge protector, which is one of the lightning protection products independently developed by an enterprise. The surge protector is used to protect equipment and systems from high voltage and high current impacts, so the product quality is particularly important.

[0003] After the surge protector is potted, a connecting piece needs to be manually soldered. When welding, the worker holds the connecting piece for welding. Since the lap welding method is adopted, the hand cannot shake during welding, otherwise false soldering will occur, affecting the product quality. At the same time, when welding, it is also necessary to consider that the connecting piece should be aligned with the second welding point. After welding the first welding point, when welding the second welding point, there is often a problem that there is a gap between the connecting piece and the second welding point. When welding, it is also necessary to press the connecting piece to make it contact with the second welding point. The pressing force is uncontrollable and easily deforms the connecting piece, affecting the product appearance; moreover, heat is generated during the welding process, resulting in a hot hand phenomenon. At this time, if the hand is released, a false soldering problem will occur. Content of the Utility Model

[0004] In view of the above-mentioned disadvantages and deficiencies, the utility model provides a surge protector welding tooling to improve the welding quality and efficiency, meet the product quality requirements, and ensure the safety and reliability of the product.

A positioning groove is opened on one side of the installation groove. The surge protector is slidably connected to the positioning groove and fixed inside the installation groove.

[0007] The pressing unit includes a horizontal adjustment unit and a vertical adjustment unit. The horizontal adjustment unit is rotatably connected to the positioning unit. The vertical adjustment unit is slidably connected to the horizontal adjustment unit. The end of the vertical adjustment unit presses on the connecting piece, and the position of the pressed connecting piece is adjusted by the cooperation of the horizontal adjustment unit and the vertical adjustment unit.

Specific embodiments

[0021] The present utility model will be further described below with reference to the accompanying drawings of the specification. As Figure 2-7 shown, the present utility model is a welding tooling for a surge protector, which is characterized in that it includes a positioning unit and a pressing unit. The pressing unit is rotatably connected to the positioning unit above the positioning unit. The surge protector is fixed in the positioning unit. By adjusting the rotation angle of the pressing unit, the connecting piece 4 to be welded and the welding point are fixed. The positioning unit is of a concave structure, and an installation groove 6 adapted to the outer shell of the surge protector 2 is provided inside the positioning unit. A positioning groove 7 is provided on one side of the installation groove 6. The surge protector 2 is slidably connected to the positioning groove 7 and fixed inside the installation groove 6 to prevent the surge protector 2 from moving.

[0022] The pressing 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 presses on the connecting piece 4. By cooperating with the horizontal adjustment unit and the vertical adjustment unit, the position of the pressed connecting piece 4 is adjusted.

[0023] Further, the horizontal adjustment unit includes a rotating column 8 and a rotating shaft 17. The rotating shaft 17 is fixedly arranged at the lower end of the rotating column 8. A journal 16 is provided below the rotating shaft 17. The journal 16 is inside the positioning unit. The entire horizontal adjustment unit is horizontally rotated by the positioning pin 15 provided outside the positioning unit passing through the positioning hole 22 and cooperating with the journal 16. A fastening screw 10 is provided at the upper end of the rotating column 17. The rotating shaft 17 of the rotating column 8 is inserted into the column installation hole 21, and the positioning pin 15 is tightened so that its shoulder 14 cooperates with the journal 16 of the positioning pin 15. At this time, the rotating column 8 can rotate on the tooling body 1 but cannot move up and down.

[0024] Further, the vertical adjustment unit includes a cross beam 9, a crimping rod 13 and a lifting knob 11. The cross beam 9 is slidably connected to the rotating column 8 through a cross beam mounting hole 20 and is fixed in position by a fastening screw 10. A spring 12 is sleeved on the crimping rod 13. The upper end of the crimping rod 13 extends out of a locking hole 19 at the upper end of the cross beam 9 and is fixedly connected to the lifting knob 11. The crimping rod 13 is slidably connected to the cross beam 20 through a press rod positioning hole 18 provided at the end of the cross beam 9. A baffle is provided on the crimping rod 13, and the diameter of the baffle is larger than the diameter of the press rod positioning hole 18.

[0025] The crimping rod 13 can move up and down in the press rod positioning hole 18, and generates its own weight and the pressure of the spring 12 on the object at the lower end of the crimping rod 13. The magnitude of the pressure is related to the hardness and compression amount of the spring 12; the selected spring 12 can achieve crimping without deforming the connecting piece 4.

[0026] During use, place the surge protector 2 into the tooling, place the connecting piece 4 at the welding position. When welding, loosen the fastening screw 10, turn the crimping rod 13 to the side of the first welding point 3, hold the tail end of the connecting piece 4 by hand to make its front end contact the first welding point 3 of the surge protector, pull the lifting knob 11 by hand, move the cross beam 9, and press the lower end of the crimping rod 13 onto the connecting piece 4 as Figure 6 shown in the position (at this time, even if the hand shakes slightly, the welding quality will not be affected under the action of the pressure). Then adjust the connecting piece 4 to align with the second welding point 5 and weld the first welding point 3; then pull the lifting knob 11 while moving and rotating the cross beam 9 to make the lower end of the crimping rod 13 press on Figure 7 the connecting piece 4 position shown, press the connecting piece 4 until it contacts the second welding point 5, and weld the second welding point 5; finally, pull the lifting knob 11 to turn the cross beam 9 outside the tooling body 1 and take out the surge protector 2 to complete the whole welding process.
