Description

Technical Field

[0001] This utility model belongs to the field of projection welding electrode technology, and more specifically, it relates to a modular projection welding electrode. Background Technology

[0002] The projection electrode is made of highly conductive material and is responsible for conducting the welding current to the projection point of the workpiece, providing the heat required for welding, and applying appropriate pressure to the workpiece to ensure tight contact, prevent spatter, and promote metal fusion. Its shape and size are specially designed to precisely control the heat distribution, prevent overheating and deformation of other parts of the workpiece, and position the workpiece to ensure the accuracy of the weld joint. Existing projection electrodes are connected by threads. Although this connection is relatively simple in structure and has a certain degree of stability, it has obvious drawbacks in actual operation. Frequent twisting is required during installation and disassembly, which is inconvenient. Therefore, a modular projection electrode is proposed. Utility Model Content

A slot is formed on the outer side of the connecting rod. A movable sleeve is slidably connected to the inner side of the second mounting groove. The upper end of the connecting rod is inserted into the inner side of the movable sleeve. Multiple first buckles are fixed to the bottom surface of the movable sleeve, and two second buckles are fixed to the top surface of the movable sleeve. An inclined surface is formed at the upper end of each of the two second buckles. Two movable grooves are formed on the upper outer side of the connecting seat, and connecting blocks are slidably connected to the inner sides of each of the two movable grooves. One end of each connecting block is engaged with the upper end of a second buckle. A first threaded groove is also formed on the upper outer side of the connecting seat. A connecting sleeve is also formed on the upper outer side of the connecting seat. A second threaded groove is formed on the upper inner side of the connecting sleeve. Opposite ends of the two connecting blocks are fixedly connected to the inner side of the connecting sleeve.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figures 1 to 4This utility model provides a technical solution: a modular projection welding electrode, including an electrode body 1 and a connecting seat 2. The connecting seat 2 has a first mounting groove 3 and a second mounting groove 4 inside. A connecting handle 5 is fixed to the top surface of the electrode body 1, and a connecting rod 6 is fixed to the upper end of the connecting handle 5. A slot 7 is formed on the outer side of the connecting rod 6. A movable sleeve 8 is slidably connected to the inner side of the second mounting groove 4. The upper end of the connecting rod 6 is inserted into the inner side of the movable sleeve 8. A plurality of first buckles 9 are fixed to the bottom surface of the movable sleeve 8, and two second buckles 10 are fixed to the top surface of the movable sleeve 8. The upper end of each of the two second buckles 10 has an inclined surface 11. Two movable grooves 12 are formed on the upper outer side of the connecting seat 2. A connecting block 13 is slidably connected to the inner side of each of the two movable grooves 12. One end of the connecting block 13 is connected to the second buckle 9. The upper end of buckle 10 is engaged with the connecting seat 2. The upper outer side of the connecting seat 2 is also provided with a first threaded groove 15. The upper outer side of the connecting seat 2 is also provided with a connecting sleeve 14. The upper inner side of the connecting sleeve 14 is provided with a second threaded groove 16. The opposite ends of the two connecting blocks 13 are fixedly connected to the inner side of the connecting sleeve 14. The first mounting groove 3 has a frustum-shaped structure. The connecting handle 5 has a frustum-shaped structure. One end of the connecting handle 5 is engaged with the inner side of the first mounting groove 3. The slot 7 has an annular structure. The multiple first buckles 9 have a structure that is thin at the top and thick at the bottom. The lower ends of the multiple first buckles 9 are engaged with the inner side of the slot 7. The two movable grooves 12 have a fan-shaped structure. The interior of the two movable grooves 12 is connected to the interior of the second mounting groove 4. The inner side of the second threaded groove 16 is threadedly connected to the inner side of the first threaded groove 15.

[0023] When installing the electrode body 1, the connecting handle 5 on the electrode body 1 is inserted into the first mounting groove 3 on the connecting seat 2. During this process, the connecting rod 6 on the connecting handle 5 is inserted into multiple first buckles 9 and movable sleeves 8. The connecting handle 5 pushes the first buckles 9 and movable sleeves 8 upward along the second mounting groove 4. Since the first buckles 9 are all of a thinner upper and thicker lower structure, the lower end of the first buckle 9 is squeezed by the inner wall of the second mounting groove 4, thus converging towards the middle, so that the lower end of the first buckle 9 engages with the groove 7 on the connecting rod 6. As the movable sleeve 8 continues to move upward, the second buckle 10 on the movable sleeve 8 encounters the connecting block 13, and the second buckle... The inclined surface 11 on 10 slips against the connecting block 13, causing the second buckle 10 to retract towards the middle. After the upper protrusion of the second buckle 10 passes the connecting block 13, the second buckle 10 and the connecting block 13 are engaged. When it is necessary to disassemble the electrode body 1, the connecting block 13 is slid along the movable groove 12 by rotating the connecting sleeve 14, so that the connecting block 13 is disengaged from the second buckle 10. Then, the electrode body 1 can be pulled out. Through the above process, the electrode body 1 can be quickly disassembled and installed, which solves the problem that the connection is made by threads, and the process is inconvenient due to the need for frequent twisting during installation and disassembly.

[0024] The specific usage and function of this embodiment: When installing the electrode body 1, the connecting handle 5 on the electrode body 1 is inserted into the first mounting groove 3 on the connecting seat 2. During this process, the connecting rod 6 on the connecting handle 5 is inserted into multiple first buckles 9 and movable sleeves 8. The connecting handle 5 pushes the first buckles 9 and movable sleeves 8 upward along the second mounting groove 4. Since the first buckles 9 are all of a thin upper and thick lower structure, the lower end of the first buckle 9 is squeezed by the inner wall of the second mounting groove 4, thus closing towards the middle, so that the lower end of the first buckle 9 engages with the groove 7 on the connecting rod 6. As the movable sleeve 8... Continuing to move upwards, the second latch 10 on the movable sleeve 8 encounters the connecting block 13. The inclined surface 11 on the second latch 10 slips against the connecting block 13, causing the second latch 10 to retract towards the connecting block 13. After the upper protrusion of the second latch 10 passes the connecting block 13, the second latch 10 and the connecting block 13 are engaged. When it is necessary to disassemble the electrode body 1, the connecting sleeve 14 is rotated to drive the connecting block 13 to slide along the movable groove 12, causing the connecting block 13 to disengage from the second latch 10. Then, the electrode body 1 can be pulled out. Through the above process, the electrode body 1 can be quickly disassembled and installed.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
