[0002] The bicycle frame is the skeleton of the entire bicycle. The load capacity of a bicycle is an important indicator of its quality, and the frame determines the load capacity. Therefore, the bicycle frame is a crucial structure that determines the performance of a bicycle. The rear frame of a bicycle typically includes the head tube, bottom bracket, top forks, bottom forks, and dropouts. These components are connected as one piece by welding.

[0048] like Figures 1 to 13As shown, this embodiment provides a welding clamping device for clamping and positioning a rear tripod during robotic welding. The welding clamping device includes a mounting base 10, a bottom bracket limiting assembly, a middle tube limiting assembly 30, a lower fork limiting assembly 40, an upper fork limiting assembly 50, and a tail end limiting assembly 60. The middle tube limiting assembly 30 includes an adjusting seat 31 and a middle tube positioning component. The adjusting seat 31 is adjustable in angle on the mounting base 10, and the middle tube limiting component 32 is adjustable in position on the adjusting seat 31, allowing it to abut against the middle tube. The lower fork limiting assembly 40 includes a support block 41, the position of which is adjustable. The upper fork limiting component 50 is adjustablely mounted on the mounting base 10 and is rotatable relative to the mounting base 10. The upper fork limiting component 50 includes several first positioning members 51 and several second positioning members 52. The several first positioning members 51 are used to position the upper fork, and the several second positioning members 52 can elastically abut against the fork bones of the upper fork. The tail end limiting component 60 is adjustablely mounted on the mounting base 10 and includes two spaced positioning structures. The two positioning structures are used to position the two claws or two barrel shafts in a one-to-one correspondence.

[0049] Specifically, in this embodiment, as Figures 1 to 3 As shown, the mounting base 10 is used to connect to the robotic arm, thereby ensuring the displacement reliability of the welding clamping device during the welding process. The bottom bracket limiting assembly can limit the bottom bracket of the rear tripod, thereby initially positioning the rear tripod. The adjusting seat 31 of the middle tube limiting assembly 30 is adjustablely set on the mounting base 10, while the middle tube limiting member 32 is adjustablely set on the adjusting seat 31, so that the position and angle of the middle tube limiting member 32 relative to the bottom bracket limiting assembly are adjustable, thus making it suitable for rear tripods with different relative positions of the middle tube and the bottom bracket. The lower fork limiting assembly 40 includes a support block 41, the position of which is adjustable on the mounting base 10, so that the position of the support block 41 relative to the bottom bracket limiting assembly is adjustable, thus making the welding clamping device suitable for the bottom bracket and the lower fork. The versatility of the welding clamping device is further enhanced for rear tripods with different positions. The upper fork limiting component 50 is adjustablely positioned on the mounting base 10 and can rotate relative to the mounting base 10. This allows the position and angle of the upper fork limiting component 50 relative to the bottom bracket limiting component to be adjustable, thus enabling the welding clamping device to be used for rear tripods with different relative angles and positions of the bottom bracket and the upper fork, further improving the versatility of the welding clamping device. The tail end limiting component 60 is adjustablely positioned on the mounting base 10, allowing the relative position of the tail end limiting component 60 and the bottom bracket limiting component to be adjustable. This enables the welding clamping device to be used for rear tripods with different relative angles of the bottom bracket and the tail end structure, thus giving the welding clamping device good versatility.

[0050] Specifically, in this embodiment, as Figures 11 to 13 As shown, the support block 41 is provided with a limiting groove 411. There are two limiting grooves 411. The two limiting grooves 411 are used to limit the two fork arms of the lower fork in a one-to-one correspondence, thereby improving the effectiveness of positioning and ensuring the quality of welding.

[0051] Specifically, in this embodiment, as Figure 2 and Figure 13 As shown, the upper fork limiting assembly 50 includes several first positioning members 51 and several second positioning members 52. The first positioning members 51 are used to position the upper fork, and the several second positioning members 52 can elastically abut against the fork bones of the upper fork. This arrangement can effectively position the upper fork and effectively prevent the upper fork from shifting during the welding process, ensuring the effectiveness of the upper fork limiting and thus ensuring the welding quality of the rear tripod.

[0052] Specifically, in this embodiment, as Figures 11 to 13 As shown, the tail end limiting component 60 includes two spaced and detachably configured positioning structures. The two positioning structures are used to position the two hooks or the two barrel shafts in a one-to-one correspondence. Specifically, in this embodiment, the two positioning structures are spaced apart, which can limit the two hooks or the two barrel shafts, thereby ensuring the stability of the rear tripod position. Moreover, the positioning structures can be replaced according to the hooks or barrel shafts, further improving versatility.

[0053] Furthermore, such as Figures 4 to 6 As shown, the bottom bracket limiting assembly includes a mounting bridge 21, a first limiting member 22, and a second limiting member 23. The mounting bridge 21 is disposed on the mounting base 10 and includes two opposing mounting platforms 211. The first limiting member 22 is detachably mounted on one mounting platform 211, and the second limiting member 23 is detachably mounted on the other mounting platform 211. The first limiting member 22 and the second limiting member 23 are opposite to each other and can move closer to or further away from each other along a first horizontal direction. Specifically, in this embodiment, the mounting bridge 21 is disposed on the mounting base 10, thereby ensuring the positional stability of the first limiting member 22 and the second limiting member 23, and thus improving the positional accuracy of the bottom bracket. The two opposing mounting platforms 211 are connected by a connecting platform 212, thereby ensuring the relative position of the two mounting platforms 211 and thus ensuring the installation stability of the bottom bracket. The first limiting member 22 and the second limiting member 23 can move closer to or further away from each other, thereby ensuring the clamping and loosening of the bottom bracket and ensuring the limiting stability of the bottom bracket.

[0054] Optionally, in this embodiment, as Figure 5As shown, the first limiting member 22 includes a first cylinder 221 and a second cylinder 222. The first cylinder 221 and the second cylinder 222 are coaxially arranged, and the outer diameter of the first cylinder 221 is larger than the outer diameter of the second cylinder 222. The first cylinder 221 is connected to a mounting platform 211. The bottom bracket is sleeved on the outer periphery of the second cylinder 222 and abuts against the end face of the first cylinder 221 facing the second cylinder 222. The second limiting member 23 includes a tapered abutment post 231. A portion of the tapered abutment post 231 can extend into the opening of the bottom bracket, thereby ensuring that the bottom bracket is stably limited.

[0055] Optionally, in this embodiment, both the first limiting member 22 and the second limiting member 23 can be replaced according to the specific size of the bottom bracket, thereby further improving the versatility of the welding clamping device.

[0056] Optionally, in this embodiment, as Figure 6 As shown, the bottom bracket limiting assembly also includes a second driving member 24 and a third driving member 25. The second driving member 24 is connected to one mounting platform 211, and the third driving member 25 is connected to another mounting platform 211. The output end of the second driving member 24 is connected to the first limiting member 22 and is used to drive the first limiting member 22 to extend and retract. The output end of the third driving member 25 is connected to the second limiting member 23 and is used to drive the second limiting member 23 to extend and retract. This allows the first limiting member 22 and the second limiting member 23 to move closer to or further away from each other, thereby ensuring that bottom brackets of different lengths can be properly limited, thus ensuring the versatility of the welding clamping device.

[0057] Preferably, in this embodiment, the second driving member 24 and the third driving member 25 are both telescopic cylinders. In another embodiment, the second driving member 24 and the third driving member 25 can also be other structures capable of linear motion, such as linear motors, etc., which are not limited here.

[0063] Furthermore, such as Figure 7 and Figure 8As shown, the middle tube limiting assembly 30 also includes a first adjusting mechanism, which includes a first lead screw 33, a first lead screw 33 nut, and a slider 34. The slider 34 is slidably disposed on the adjusting seat 31, and the slider 34 and the first lead screw 33 nut are fixedly connected. The first lead screw 33 and the first lead screw 33 nut are threadedly connected. When the first lead screw 33 rotates, it can drive the slider 34 to move, thereby adjusting the setting position of the slider 34 on the adjusting seat 31. The middle tube limiting member 32 is fixedly disposed on the slider 34. Specifically, in this embodiment, the slider 34 is slidably disposed on the adjusting seat 31 via a slide rail. The two ends of the first lead screw 33 are rotatably disposed on the adjusting seat 31 via bearings. The lead screw nut and the slider 34 are fixedly connected. One end of the first lead screw 33 is connected to a handwheel. By rotating the handwheel, the first lead screw 33 can be rotated, thereby driving the slider 34 to move, thereby adjusting the relative position of the slider 34 and the adjusting seat 31, and thus adjusting the setting position of the middle tube limiting member 32 disposed on the slider 34, ensuring the versatility of the welding clamping device.

[0064] Optionally, in this embodiment, as Figure 8 As shown, the middle tube limiting assembly 30 also includes a first plate 35 and a second plate 36, which are connected.

[0065] Furthermore, such as Figure 7 and Figure 8 As shown, the middle tube limiting assembly 30 also includes a first driving member 37, which is connected to the adjusting seat 31. The middle tube limiting member 32 is disposed at the output end of the first driving member 37.

Specifically, in this embodiment, the first driving member 37 is connected to the side of the second plate 36 opposite to the bottom bracket limiting assembly 20, and the output end of the first driving member 37 is connected to the middle tube limiting member 32. The first driving member 37 can drive the middle tube limiting member 32 to move, thereby ensuring effective positioning of the middle tube and ensuring good positioning effect for middle tubes of different lengths, ensuring the versatility and effectiveness of the middle tube limiting assembly 30.

[0066] Optionally, in this embodiment, the first driving member 37 is a telescopic cylinder. In another embodiment, the first driving member 37 may also be other structures capable of linear motion, such as a linear motor, etc., which are not limited here.

[0067] Optionally, in this embodiment, as Figure 7 and Figure 8As shown, a tapered abutment post 231 is provided at one end of the middle tube limiting component 32 near the bottom bracket limiting component 20.

One end of the second lead screw 44 is provided with a handwheel. By rotating the handwheel, the second lead screw 44 can be rotated, thereby driving the second lead screw nut to move along the second horizontal direction, thereby moving the sliding seat 42 along the second horizontal direction and disposing it on the mounting base 10. This arrangement can adjust the position of the support block 41 relative to the bottom bracket limiting component in the second horizontal direction, enabling the welding clamping device to be applicable to rear tripods with different relative positions of the bottom bracket and the lower fork, thus improving the versatility of the welding clamping device.

[0071] Specifically, in this embodiment, as Figure 12As shown, one end of the adjusting member 43 is provided with a vertically extending groove 431, and the sliding seat 42 is provided with a limiting threaded hole.

After passing through the groove 431, the second fastener 432 is threadedly connected to the limiting threaded hole, thereby ensuring the stability of the relative position of the adjusting member 43 and the sliding seat 42. At the same time, the second fastener 432 can slide along the groove 431, thereby adjusting the height of the adjusting member 43 in the vertical direction, thereby improving the flexibility of the relative position of the support block 41 and the five-way pipe limiting assembly, and further improving the versatility of the welding clamping device.

[0072] Specifically, in this embodiment, as Figure 11 and 12 As shown, the support block 41 is slidably disposed in the adjustment groove 433 extending along the second horizontal direction on the adjustment member 43, which can further adjust the position of the support block 41 relative to the five-way limiting component 20 along the second horizontal direction, thereby improving the versatility and adjustability of the welding clamping device.

[0073] Optionally, a slide rail is also provided on the mounting base 10, and part of the structure of the sliding block is limited to the slide rail and can slide along the slide rail, thereby guiding the sliding base 42 and improving the stability of the sliding base 42 during the sliding process.

[0074] Furthermore, such as Figure 13 As shown, the upper fork limiting assembly 50 also includes an adjusting block 53, a third adjusting mechanism 54, and a mounting structure. The adjusting block 53 is fixedly disposed on the sliding seat 42. The third adjusting mechanism 54 is disposed between the mounting structure and the adjusting block 53. The third adjusting mechanism 54 is used to adjust the setting position of the mounting structure on the adjusting block 53. One of the third adjusting mechanism 54 and the adjusting block 53 is provided with a second through hole, and the other is provided with a second adjusting groove 531. The third fastener 543 passes through the second through hole and the second adjusting groove 531 to connect the third adjusting mechanism 54 to the adjusting block 53. The third fastener 543 can slide along the second adjusting groove 531, thereby adjusting the setting angle of the third adjusting mechanism 54 relative to the adjusting block 53. A plurality of first positioning members 51 and a plurality of second positioning members 52 are all mounted on the mounting structure.

[0075] Specifically, in this embodiment, as Figure 13 As shown, the adjustment block 53 of the upper fork limit component 50 is fixedly set on the sliding seat 42. When the position of the sliding seat 42 is adjusted, the setting positions of the upper fork limit component 50 and the lower fork limit component 40 can be adjusted simultaneously, thereby improving the adjustment efficiency.

[0076] Specifically, in this embodiment, as Figure 13As shown, the third adjustment mechanism 54 includes a guide rail 541, a sliding member 542, and a fixing member. The guide rail 541 is disposed on the adjustment block 53, and the sliding member 542 is disposed on the mounting structure. The sliding member 542 can slide along the guide rail 541, and the fixing member can limit the sliding member 542 to any position on the guide rail 541. In this way, the relative position of the mounting structure connected to the sliding member 542 can be adjusted, thereby adjusting the relative position of a number of first positioning members 51 and a number of second positioning members 52 relative to the five-way pipe limiting assembly, further improving the versatility and flexibility of the welding clamping device.

[0077] Optionally, in this embodiment, the fixing component is a lead screw and a lead screw nut pair. The lead screw and lead screw nut pair can not only guide it, but also ensure the setting position of the sliding component 542 relative to the guide rail 541, thereby improving the stability during use.

[0078] Specifically, in this embodiment, as Figure 13 As shown, the guide rail 541 is provided with a second through hole, and the adjusting block 53 is provided with a second adjusting groove 531. The third fastener 543 includes a third bolt and a third nut. The third bolt passes through the second adjusting groove 531 and the second through hole and is threadedly connected to the third nut, thereby connecting the guide rail 541 and the adjusting block 53. At the same time, the third bolt can slide along the second adjusting groove 531. The second adjusting groove 531 is an arc-shaped groove. This arrangement can adjust the relative angle between the guide rail 541 and the adjusting block 53, and further adjust the relative positions of the first positioning members 51 and the second positioning members 52 relative to the five-way pipe limiting assembly, thereby improving the versatility and flexibility of the welding clamping device.

[0079] Furthermore, such as Figure 13As shown, the mounting structure includes a first mounting rod 551, a second mounting rod 552, and a connecting rod 553. The first mounting rod 551 and the second mounting rod 552 are parallel and spaced apart. The connecting rod 553 connects the first mounting rod 551 and the second mounting rod 552. At least two first positioning members 51 are slidably and spaced apart on the first mounting rod 551, at least two first positioning members 51 are slidably and spaced apart on the second mounting rod 552, and a plurality of second positioning members 52 are spaced apart on the connecting rod 553. Specifically, in this embodiment, four first positioning members 51 are provided, two of which are slidably and spaced apart on the first mounting rod 551, and the other two are slidably and spaced apart on the second mounting rod 552. These four first positioning members 51 are arranged at the four corners, thereby limiting the upper fork. Two second positioning members 52 are provided, arranged spaced apart on the connecting rod 553. The second positioning members 52 can elastically abut against the fork bone of the upper fork, thereby effectively preventing the upper fork from moving during the rotation of the welding clamping device, thus ensuring the installation stability of the upper fork. Furthermore, two of the first positioning members 51 are slidably disposed on the first mounting rod 551, and the other two are slidably disposed on the second mounting rod 552. This makes the relative positions of the four first positioning members 51 adjustable, so that the upper fork limiting component 50 can normally limit the upper fork of different sizes, improving the versatility and stability of the welding clamping device.

[0080] Furthermore, such as Figure 2 As shown, the second positioning member 52 includes a positioning post 521 and an elastic member 522. The positioning post 521 is slidably disposed on the connecting rod 553, and the elastic member 522 is elastically disposed between the positioning post 521 and the connecting rod 553 facing the fork ribs of the upper fork. Specifically, in this embodiment, the elastic member 522 is elastically disposed between the positioning post 521 and the connecting rod 553 facing the fork ribs of the upper fork. The elastic force of the elastic member 522 ensures that the positioning post 521 can always abut against the fork ribs of the upper fork, thereby ensuring the stability of the upper fork's positioning.

[0081] Optionally, in this embodiment, as Figure 13 As shown, the connecting rod 553 includes a first connecting rod 5531, a second connecting rod 5532, and a third connecting rod 5533. The first connecting rod 5531 is connected between the second connecting rod 5532 and the third connecting rod 5533, and both the second connecting rod 5532 and the third connecting rod 5533 can slide relative to the first connecting rod 5531. One second positioning member 52 is disposed on the second connecting rod 5532, and the other second positioning member 52 is disposed on the third connecting rod 5533. The first connecting rod 5531 and the sliding member 542 are connected by bolts, which further improves the versatility of the upper fork limiting assembly 50.

[0082] Furthermore, such as Figure 13 As shown, the positioning structure includes a fixed part 61 and a movable part 62. The fixed part 61 is fixedly disposed on the mounting base 10, and the movable part 62 can move closer to or away from the fixed part 61 to limit the hook or barrel shaft. Specifically, in this embodiment, the positioning structure also includes a positioning seat 63, which is provided with a positioning groove 631. Both positioning structures include a fixed part 61 and a movable part 62. Both fixed parts 61 are disposed in the positioning groove 631, and the two fixed parts 61 are disposed opposite to each other and are pressed into the positioning groove 631 by clamps 632. One movable part 62 is disposed opposite to one fixed part 61, and the positioning structure also includes two fourth driving members 64. The output parts of the two fourth driving members 64 are connected to the two movable parts 62 in a one-to-one correspondence. The fourth driving members 64 can drive the movable part 62 to extend or retract, so that the movable part 62 can move closer to or away from the corresponding fixed part 61 to limit the hook or barrel shaft.

[0083] Specifically, in this embodiment, the fixing part 61 and the movable part 62 can adopt different structures depending on the hook or barrel shaft to ensure that the hook or barrel shaft is limited, and the size of the fixing part 61 and the movable part 62 can also be changed or replaced according to the size of the corresponding hook and barrel shaft, thus having strong flexibility.

[0084] Optionally, in this embodiment, the fourth driving member 64 is a telescopic cylinder. In another embodiment, the fourth driving member 64 can also be other structures capable of linear motion, such as a linear motor, etc., which are not limited here.

[0085] Optionally, in this embodiment, one of the fourth drive members 64 is disposed on the outside of the adjustment block 53 of the upper fork limiting component 50, which can improve space utilization and facilitate air supply to the fourth drive member 64.
