[0022] 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.

[0023] As attached Figure 1 - Appendix Figure 4 The present invention relates to a modular welding machine electrode quick-change buckle device. The modular welding machine electrode quick-change buckle device is equipped with a buckle assembly. The buckle assembly can use gravity to quickly discharge the welding machine electrode 3. The buckle post 5 and the buckle strip 6 simultaneously position and insert the positioning ring 2 and the welding machine electrode 3. The magnet 8 and the magnetic block 7 quickly magnetically lock together. The specific structure of the buckle assembly is as follows.

[0024] In this embodiment, as shown in the appendix Figure 1 - Appendix Figure 3 As shown, the snap-fit ​​assembly includes: a welding electrode 3, inserted into the inner wall of the positioning ring 2, with a protrusion 4 fixedly connected to the outer wall of the welding electrode 3, and the protrusion 4 being inserted into the positioning ring 2; a snap-fit ​​post 5, inserted through the interior of the welding electrode 3, with a snap-fit ​​strip 6 fixedly connected to the outer wall of the snap-fit ​​post 5, and both the welding electrode 3 and the positioning ring 2 being slidably connected to the snap-fit ​​strip 6; and a magnetic block 7, fixedly connected to one end of the snap-fit ​​post 5, with a magnet 8 magnetically connected to one side of the magnetic block 7. The positioning ring 2 is used to position the protrusion 4 and the welding electrode 3, and the inner wall of the positioning ring 2 is a smooth surface. Both the positioning ring 2 and the welding electrode 3 are inserted into the snap-fit ​​strip 6, and the outer wall of the snap-fit ​​strip 6 is a smooth surface.

[0025] In this embodiment, as shown in the appendix Figure 2 As shown, an insulating block 9 is fixedly connected between the magnet 8 and the welding machine module base 1. The insulating block 9 is made of rubber so that it can insulate and support the magnet 8, and facilitate the magnet 8 to stably magnetically connect to the magnetic block 7.

[0026] In this embodiment, as shown in the appendix Figure 1 As shown, an electrode 13 is fixedly connected to the bottom end of the welding electrode 3. The cross-sectional area of ​​the top end of the electrode 13 is smaller than that of the bottom end, so that the electrode 13 can be connected to the welding electrode 3 and the electrode 13 forms a pointed state.

[0027] In this embodiment, as shown in the appendix Figure 1As shown, multiple mounting holes 14 are provided on the inner wall of the welding machine module base 1 near its edge. The multiple mounting holes 14 are arranged in a circumferentially equidistant pattern. The cross-sectional shape of each mounting hole 14 is annular, so that bolts can be inserted into the mounting hole 14 to install and fix the welding machine module base 1 to the welding end, thereby realizing the circumferentially distributed installation of the welding machine module base 1.

[0028] In use, the modular welding electrode quick-change buckle device of this technology is installed and fixed to the welding module base 1 and the welding end by inserting bolts into the mounting hole 14. At the same time, the welding module base 1 supports the positioning ring 2, the positioning ring 2 positions and supports the buckle post 5, and the buckle post 5 positions and supports the buckle strip 6. When it is necessary to disassemble and replace the welding electrode 3, the buckle post 5 is moved to the right. The buckle post 5 drives the buckle strip 6 to move to the right, and the buckle strip 6 drives the magnetic block 7 to move to the right. Force is applied to make the magnetic block 7 and the magnet 8 magnetically separate. At the same time, the welding module base 1 supports the insulating block 9, the insulating block 9 supports the magnet 8, and the magnet 8 and the magnetic block 7 magnetically separate. After separation, the buckle post 5 and the buckle strip 6 can quickly move to the right and separate along the positioning ring 2 and the inner wall of the welding electrode 3. Then, the welding electrode 3 drives the protrusion 4 to move down under the action of gravity, and the welding electrode 3 drives the electrode end 13 to move down, quickly performing a horizontal magnetic snap-lock separation. Gravity is used to make the welding electrode 3 quickly discharged.

[0029] The new welding electrode 3 is inserted into the positioning ring 2. At the same time, the new welding electrode 3 moves the new protrusion 4 upward and positions it inside the positioning ring 2. Then, the left-hand locking post 5 moves the locking strip 6. The locking post 5 and the locking strip 6 simultaneously position and insert the positioning ring 2 and the welding electrode 3 until the locking post 5 moves the magnetic block 7 to contact the magnet 8. This allows the magnet 8 and the magnetic block 7 to quickly magnetically lock together.

[0030] In this embodiment, as shown in the appendix Figure 3 - Appendix Figure 4 As shown, another part of the locking post 5 is fixedly connected to a pull block 11, and a pull strip 12 is fixedly connected to the outer wall of the pull block 11. A positioning sleeve 10 is slidably connected to the outer wall of the locking post 5 near the position of the pull block 11. The positioning sleeve 10 is fixedly connected to the welding machine module base 1, and the locking strip 6 is slidably connected to the positioning sleeve 10.

[0031] When using the modular welding machine electrode quick-change buckle device, if the locking post 5 moves to the right, the pull bar 12 is pulled by hand. The pull bar 12 drives the pull block 11 to move to the right, and the pull block 11 drives the locking post 5 and the locking bar 6 to move to the right synchronously. In this way, the locking post 5 and the locking bar 6 can be guided and moved to the right stably along the inside of the positioning sleeve 10, which facilitates the positioning and rightward movement of the locking post 5 and the locking bar 6 according to the specified position, and stably guides the rightward movement.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
