Technical Field

[0001] This utility model relates to the field of welding equipment technology, and specifically discloses a welding device that facilitates the replacement of welding heads. Background Technology

[0002] Welding equipment refers to tools, machines, and related auxiliary devices used to join metal or thermoplastic materials to achieve a permanent bond through heating, pressurization, or a combination of both.

[0003] The welding heads of existing welding equipment are usually fixed with bolts. When replacing them, special tools are required for disassembly, which is cumbersome and time-consuming. This is especially true on production lines that need to frequently switch welding head types, which seriously affects work efficiency. Furthermore, frequent disassembly and assembly of welding heads can cause wear at the connection points, leading to poor contact between the welding head and the equipment body and causing unstable electrical conductivity. Utility Model Content

[0004] This invention proposes a welding device that facilitates the replacement of welding heads, enabling convenient and quick replacement of welding heads, avoiding impact on work efficiency, and preventing unstable electrical conductivity caused by poor contact between the welding head and the device body due to wear at the connection point.

[0005] This utility model is implemented as follows: a welding device that facilitates the replacement of welding heads includes a welding robotic arm, a mounting block is fixedly connected to the right side wall of the welding robotic arm, a welding head is provided on the right side wall of the mounting block, and a connecting mechanism is provided between the mounting block and the welding head.

[0006] The connecting mechanism includes an installation groove on the right side wall of the mounting block. The inner side wall of the installation groove has two symmetrically distributed guide grooves with open right ends. The inner side walls of the two guide grooves are provided with symmetrically distributed fixing grooves. The opposite side walls of the two fixing grooves are open.

[0007] A connecting block is fixedly connected to the left side wall of the welding head, and a mounting post that is electrically connected to the welding head and matches the mounting groove is fixedly connected to the left side wall of the connecting block. Two symmetrically distributed locking blocks that match the two guide grooves and the two fixing grooves are fixedly connected to the left end of the outer wall of the mounting post.

[0008] An anti-breakage mechanism is provided between the mounting groove and the mounting column.

[0009] As a preferred embodiment of the present invention, which facilitates the replacement of welding heads, the anti-disconnection mechanism includes a conductive block that is slidably connected inside the mounting groove and abuts against the left end of the mounting column. A conductive spring that is electrically connected to the main body of the equipment is fixedly connected between the left inner sidewall of the mounting groove and the conductive block.

[0010] As a preferred embodiment of the present invention, which facilitates the replacement of welding heads, the outer wall of the mounting block is fitted with a limiting ring that abuts against the left side wall of the connecting block, the right side wall of the limiting ring is fixedly connected with a plurality of arrayed limiting pins, and the left side wall of the connecting block is provided with a plurality of limiting grooves that respectively match the plurality of limiting pins.

[0011] As a preferred embodiment of the present invention, which facilitates the replacement of welding heads, the outer wall of the mounting block has two symmetrically distributed grooves located to the left of the limiting ring. A limiting strip is slidably connected inside the groove, and a return spring is fixedly connected between the limiting strip and the groove.

[0012] As a preferred embodiment of the welding equipment of this utility model that facilitates the replacement of welding heads, both the conductive block and the conductive spring are made of copper.

[0013] As a preferred embodiment of the present invention, which facilitates the replacement of welding heads, the limiting strip and the groove are slidably connected by a limiting slider and a limiting groove.

[0014] As a preferred embodiment of the welding equipment of this utility model that facilitates the replacement of welding heads, the limiting ring and the mounting block are slidably connected by a limiting slider and a limiting groove.

[0015] The beneficial effects of this utility model are:

[0016] During disassembly, the mounting column is rotated by the connecting block. The mounting column drives the two locking blocks to rotate out of the two fixed slots and into the two guide slots respectively. Then, the connecting block is pulled to the right to pull the mounting column out of the mounting slot. At the same time, the two locking blocks are moved out of the two guide slots, thereby removing the welding head. During installation, the above steps are reversed. This facilitates quick replacement of the welding head and avoids affecting work efficiency.

[0017] The conductive spring can push the conductive block to the right, so that the conductive block continues to abut against the mounting column, avoiding poor contact between the welding head and the equipment body due to wear at the connection, which could lead to unstable conductivity.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0025] Please see Figure 1-4 A welding device for easy replacement of welding heads includes a welding robotic arm 1, a mounting block 2 fixedly connected to the right side wall of the welding robotic arm 1, a welding head 3 provided on the right side wall of the mounting block 2, and a connecting mechanism provided between the mounting block 2 and the welding head 3.

[0026] The connecting mechanism includes a mounting groove 4 on the right side wall of the mounting block 2. The inner side wall of the mounting groove 4 has two symmetrically distributed guide grooves 5 with open right ends. The inner side walls of the two guide grooves 5 are provided with symmetrically distributed fixing grooves 6. The opposite side walls of the two fixing grooves 6 are open.

[0027] A connecting block 7 is fixedly connected to the left side wall of the welding head 3. A mounting post 8 that is electrically connected to the welding head 3 and matches the mounting groove 4 is fixedly connected to the left side wall of the connecting block 7. Two symmetrically distributed locking blocks 9 that match the two guide grooves 5 and the two fixing grooves 6 respectively are fixedly connected to the left end of the outer wall of the mounting post 8.

[0028] An anti-disconnection mechanism is provided between the mounting slot 4 and the mounting column 8.

[0029] In this embodiment: During disassembly, the mounting post 8 is rotated by the connecting block 7. The mounting post 8 drives the two locking blocks 9 to rotate out of the two fixing slots 6 and into the two guide slots 5 respectively. Then, the connecting block 7 is pulled to the right to pull the mounting post 8 out of the mounting slot 4. At the same time, the two locking blocks 9 are moved out of the two guide slots 5, thereby removing the welding head 3. During installation, the above steps are reversed, which facilitates quick replacement of the welding head and avoids affecting work efficiency.

[0030] The anti-disconnection mechanism can prevent poor contact between the welding head 3 and the equipment body due to wear at the connection point, which could lead to unstable electrical conductivity.

[0031] As a technical optimization of this utility model, the anti-disconnection mechanism includes a conductive block 10 that is slidably connected inside the mounting groove 4 and abuts against the left end of the mounting column 8. A conductive spring 11 that is electrically connected to the main body of the equipment is fixedly connected between the left inner sidewall of the mounting groove 4 and the conductive block 10.

[0032] In this embodiment, the conductive spring 11 can push the conductive block 10 to the right, so that the conductive block 10 continuously abuts against the mounting post 8, preventing poor contact between the conductive block 10 and the mounting post 8.

[0033] As a technical optimization of this utility model, the outer wall of the mounting block 2 is fitted with a limiting ring 12 that abuts against the left side wall of the connecting block 7. The right side wall of the limiting ring 12 is fixedly connected with a plurality of arrayed limiting pins 13. The left side wall of the connecting block 7 is provided with a plurality of limiting grooves 14 that respectively match the plurality of limiting pins 13.

[0034] In this embodiment, the connection block 7 can be limited by the cooperation between the limiting ring 12, multiple limiting pins 13 and multiple limiting grooves 14, so as to prevent the connection block 7 from rotating at will and causing the welding head 3 to loosen.

[0035] As a technical optimization of this utility model, the outer wall of the mounting block 2 has two symmetrically distributed grooves 15 located on the left side of the limiting ring 12. The grooves 15 are slidably connected to the inside of the grooves 15, and a return spring 17 is fixedly connected between the limiting strip 16 and the grooves 15.

[0036] In this embodiment: the reset spring 17 can push the limiting strip 16 out of the groove 15, and the limiting strip 16 can limit the limiting ring 12 to prevent the limiting ring 12 from sliding to the left.

[0037] As a technical optimization of this utility model, both the conductive block 10 and the conductive spring 11 are made of copper.

[0038] In this embodiment, both the conductive block 10 and the conductive spring 11 are made of copper, which enables the conductive block 10 and the conductive spring 11 to have good conductivity.

[0039] As a technical optimization of this utility model, the limiting strip 16 and the groove 15 are slidably connected by a limiting slider and a limiting groove.

[0040] In this embodiment, the limiting strip 16 and the groove 15 are slidably connected by a limiting slider and a limiting groove, which can limit the limiting strip 16 and prevent the limiting strip 16 from coming out of the groove 15.

[0041] As a technical optimization of this utility model, the limiting ring 12 and the mounting block 2 are slidably connected by a limiting slider and a limiting groove.

[0042] In this embodiment, the limiting ring 12 and the mounting block 2 are slidably connected by a limiting slider and a limiting groove, which can limit the limiting ring 12 and prevent the limiting ring 12 from rotating on the outer wall of the mounting block 2.

[0043] The working principle and usage process of this utility model are as follows: During disassembly, first press the two limiting strips 16 into the two grooves 15 to release the limiting state of the limiting ring 12. Then move the limiting ring 12 to the left. The limiting ring 12 drives multiple limiting pins 13 to move out of multiple limiting grooves 14 respectively, thereby releasing the limiting state of the connecting block 7. Then rotate the mounting post 8 through the connecting block 7. The mounting post 8 drives the two locking blocks 9 to rotate out of the two fixing grooves 6 respectively and enter the two guide grooves 5 respectively. Then pull the connecting block 7 to the right to pull the mounting post 8 out of the mounting groove 4. At the same time, the two locking blocks 9 move out of the two guide grooves 5, thereby removing the welding head 3. During installation, simply reverse the above steps to facilitate quick replacement of the welding head and avoid affecting work efficiency.

[0044] The conductive spring 11 can push the conductive block 10 to the right, so that the conductive block 10 continuously abuts against the mounting column 8, avoiding poor contact between the welding head 3 and the equipment body due to wear at the connection, which could lead to unstable conductivity.
