Description

Technical Field

[0001] This utility model relates to the field of resistance welding technology, and in particular to electrode assemblies for resistance welding. Background Technology

[0002] When performing resistance welding, it is often necessary to use an electrode assembly to perform precise welding operations. The welding pen is a key component of the electrode assembly. It transmits welding current to the contact surface of the workpiece through the electrode head, generating local heat, melting the material and forming a weld joint.

[0003] Most current electrode assemblies have a single, fixed electrode tip design. There are three types of tips: pointed, round, and flat. To ensure welding results, different types of tips are often used for the welded parts. However, changing to different types of tips usually requires two steps: disassembly and assembly, which consumes a lot of time. In addition, different types of tips are usually stored separately and are easy to lose, which limits portability and makes them inconvenient to use.

[0004] Therefore, to address the inconvenience of changing the pen tip style in existing electrode assemblies, a resistance welding electrode assembly can be designed. By rotating and adjusting, the pen tip style can be flexibly changed according to the actual needs of the welded parts, simplifying the replacement operation, saving operation time, improving the flexibility of the electrode assembly, and thus effectively enhancing the convenience of welding operations. Utility Model Content

[0005] To overcome the problems that most electrode assemblies require two steps of disassembly and assembly to change different styles of pen tips, resulting in a lot of operation time, and that different styles of pen tips are mostly stored separately, making them easy to lose and inconvenient to use, this utility model is proposed.

[0006] The technical solution of this utility model is as follows: an electrode assembly for resistance welding, comprising a pen body, a conductive component, a pen tip, an adapter groove, a conductive head, a connecting ring, a conversion component, a conductive spring, a conductive head, a locking pin, a locking ring, and a fixing component. An adapter groove is provided at one end of the pen body, a conductive head is provided inside the adapter groove, a conductive component is provided on the outside of the pen body, a connecting ring is provided at one end of the pen body, the connecting ring and the pen body are rotatably connected, a conversion component is provided on one side of the connecting ring, and a pen tip is provided on the other side of the connecting ring. Multiple sets of pen tips are provided, including pointed, flat, and round tips. A conductive spring is provided on one side of the pen tip, a conductive head is provided at one end of the conductive spring, and the outer side of the conductive head is an arc-shaped frustum. A locking pin is provided on one side of the connecting ring, multiple sets of locking pins are provided, a locking ring is provided on the outside of the connecting ring, the locking ring and the locking pin are mutually engaged, and a fixing component is provided on one side of the locking ring.

[0007] Preferably, a conversion component drives the connecting ring to rotate. Rotating the connecting ring changes the pen tip, causing the pen body to press against the conductive head. The conductive head, under pressure, compresses the conductive spring, causing the conductive spring to contract and push the conductive head into the conversion groove. The conductive head then contacts the conductive head in the conversion groove. A fixing ring is connected to the fixing component and snapped into the locking post, completing the pen tip conversion. The conductive component connects the pen body to the power supply, causing the conductive head to generate current. The current is conducted through the conductive head to the conductive head, and then through the conductive spring to the pen tip, completing the welding operation. This allows for flexible replacement of the pen tip style according to the actual needs of the welded parts, simplifying the replacement operation, saving operation time, and enhancing the convenience of welding operations.

[0008] Preferably, the conductive component includes a wire, an insulating ring, and a power switch. The wire is provided at one end of the pen body, the insulating ring is provided on the outside of the pen body, and the power switch is provided on the outside of the pen body.

[0009] Preferably, the wire and the conductive head are electrically connected to each other, and the power switch is located on the outside of the insulating ring and electrically connected to the wire.

[0010] Preferably, the conversion component includes an L-shaped groove and an L-shaped slider, with an L-shaped groove on one side of the connecting ring and an L-shaped slider on one end of the pen body.

[0011] Preferably, the L-shaped slide is an annular slide, with two sets of L-shaped slides and two sets of L-shaped sliders symmetrically arranged. The L-shaped sliders are located on the inner side of the L-shaped slide and slide along the L-shaped slide.

[0012] Preferably, the fixing component includes a fixing ring, a support rod, and a pivot. The fixing ring is provided on the outer side of the pen body, the support rod is provided on one side of the fixing ring, and the pivot is provided at one end of the support rod.

[0013] Preferably, the fixing ring is positioned above the insulating ring, the rotating shaft and the support rod are rotatably connected, and the retaining ring is positioned on the outside of the rotating shaft.

[0014] The beneficial effects of this utility model are: During welding, rotating the connecting ring changes the pen tip, causing the pen body to press against the conductive head. The conductive head, under pressure, compresses the conductive spring, causing the conductive spring to contract and push the conductive head into the adapter groove. The conductive spring then rebounds, bringing the conductive head into contact with the conductive head. The retaining ring is then snapped into the retaining post, completing the pen tip conversion. Power is then switched on to the pen body, generating current in the conductive head. This current is conducted through the conductive head to the conductive head, and then through the conductive spring to the pen tip, completing the welding operation. This addresses the common problem that changing different pen tips for most electrode components requires two steps—disassembly and assembly—consuming considerable time. Furthermore, different pen tips are often stored separately, making them prone to loss and inconvenient to use. This design enhances the convenience of welding operations.

A conversion component is provided on one side of the connecting ring 4, and a pen tip 5 is provided on the other side. There are multiple sets of pen tips 5, and the pen tips 5 are of three types: pointed, flat, and round. A conductive spring 6 is provided on one side of the pen tip 5, and a conductive head 7 is provided at one end of the conductive spring 6. The outer side of the conductive head 7 is a truncated cone with an arc shape. A locking post 8 is provided on one side of the connecting ring 4, and there are multiple sets of locking posts 8. A locking ring 9 is provided on the outer side of the connecting ring 4. The locking ring 9 and the locking post 8 are engaged and connected to each other. A fixing component is provided on one side of the locking ring 9.

[0019] Please see Figure 2In this embodiment, the conductive component includes a wire 301, an insulating ring 302, and a power switch 303. One end of the pen body 1 is provided with a wire 301, which is electrically connected to the conductive head 3. An insulating ring 302 is provided on the outside of the pen body 1, and a power switch 303 is provided on the outside of the pen body 1. The power switch 303 is located outside the insulating ring 302 and is electrically connected to the wire 301. The insulating ring 302 allows the operator to stably grip the pen body 1, and pressing the power switch 303 connects the power supply to the pen body 1, allowing the wire 301 to transmit current to the conductive head 3.

[0020] Please see Figure 2 and Figure 3 In this embodiment, the conversion component includes an L-shaped groove 401 and an L-shaped slider 402. An L-shaped groove 401 is provided on one side of the connecting ring 4. The L-shaped groove 401 is an annular groove and there are two sets of L-shaped grooves 401. An L-shaped slider 402 is provided at one end of the pen body 1. Two sets of L-shaped sliders 402 are symmetrically arranged. The L-shaped sliders 402 are located inside the L-shaped groove 401. The L-shaped sliders 402 slide along the L-shaped groove 401. When the connecting ring 4 is rotated, the L-shaped sliders 402 slide along the L-shaped groove 401, thereby ensuring the stable rotation of the connecting ring 4.

[0021] Please see Figure 1 and Figure 4 In this embodiment, the fixing component includes a fixing ring 901, a support rod 902, and a rotating shaft 903. The fixing ring 901 is provided on the outer side of the pen body 1 and is located above the insulating ring 302. The support rod 902 is provided on one side of the fixing ring 901, and the rotating shaft 903 is provided at one end of the support rod 902. The rotating shaft 903 and the support rod 902 are rotatably connected to each other. The retaining ring 9 is located on the outer side of the rotating shaft 903. The support rod 902 is connected to the fixing ring 902 through the fixing ring 901. The rotating shaft 903 is rotated to adjust the position of the retaining ring 9, thereby flexibly fastening the retaining ring 9 into the retaining post 8, so that the support rod 902 supports the fixing connecting ring 4 and flexibly locks the position of the fixing connecting ring 4.

[0022] When changing the pen tip 5, rotating the connecting ring 4 causes the L-shaped slider 402 to slide along the L-shaped groove 401, moving the corresponding pen tip 5 to one side of the pen body 1. Continuing to rotate the connecting ring 4 causes the pen body 1 to squeeze the conductive head 7. The conductive head 7 is subjected to pressure and squeezes the conductive spring 6. The conductive spring 6 contracts, causing the conductive head 7 to enter the adapter groove 2. The conductive head 7 contacts the conductive head 3 in the adapter groove 2. Subsequently, rotating the shaft 903 drives the retaining ring 9 to move, and the retaining ring 9 is fastened into the retaining post 8. The support rod 902 on the fixing ring 901 supports and fixes the connecting ring 4, locking the position of the connecting ring 4 and completing the pen tip 5 switching operation. During welding, the operator holds the insulating ring 302, aligns the pen tip 5 with the welding point, and then presses the power switch 303 to turn on the power to the pen body 1, so that the wire 301 transmits the current to the conductive head 3. The current is conducted through the conductive head 3 to the conductive head 7, and then the current flows through the conductive spring 6 to the pen tip 5, completing the welding operation through the pen tip 5.

[0023] Through the above steps, the connecting ring 4 is rotated by the conversion component. Rotating the connecting ring 4 changes the pen tip 5, causing the pen body 1 to press against the conductive head 7. The conductive head 7 is under pressure, which compresses the conductive spring 6. The conductive spring 6 contracts, causing the conductive head 7 to enter the conversion groove 2. The conductive head 7 contacts the conductive head 3 in the conversion groove 2. The fixing ring 9 is connected to the fixing component and snapped into the locking post 8, completing the conversion of the pen tip 5. The power supply to the pen body 1 is connected through the conductive component, causing the conductive head 3 to generate current. The current is conducted through the conductive head 3 to the conductive head 7, and then through the conductive spring 6 to the pen tip 5. The welding operation is completed through the pen tip 5. Thus, the style of the pen tip 5 can be flexibly changed according to the actual needs of the welded parts, simplifying the replacement operation and saving operation time.

[0024] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
