The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0037] See also Figure 1 As shown, a tail clamp mechanism for a string welding machine corresponding to a preferred embodiment of the utility model includes: a base 100; a driving structure, including a movable plate 200 installed on the base 100, a driving member 300 and a transmission seat 400 installed on the movable plate 200, the driving member 300 is suitable for driving the movable plate 200 to rise and fall in the vertical direction, there are multiple transmission seats 400, and they are arranged side by side along the first horizontal direction; a clamping structure, including a fixed plate 500 installed on the base 100 and a clamping claw 600 installed on the fixed plate 500, the clamping claw 600 and the transmission seat 400 are matched in a one-to-one transmission manner, the clamping claw 600 gradually opens in response to the rise of the transmission seat 400, and gradually closes in response to the descent of the transmission seat 400; wherein, an adjustment structure is provided between each transmission seat 400 and the movable plate 200, and the adjustment structure is suitable for driving the transmission seat 400 to adjust its position in the vertical direction.

[0038] The utility model separates the movable plate 200 from the transmission seat 400, and can increase or decrease the transmission seat 400 according to actual needs to adapt to different clamping requirements; since the clamping jaws 600 gradually open in response to the rise of the transmission seat 400, and gradually close in response to the descent of the transmission seat 400, and an adjustment structure is provided between the transmission seat 400 and the movable plate 200, when the transmission seat 400 is installed on the movable plate 200, the position of each transmission seat 400 in the vertical direction can be adjusted independently, thereby adjusting the opening and closing of the clamping jaws 600, ensuring that each clamping jaw 600 opens and closes synchronously in a completely consistent manner.

[0039] Further, refer to Figures 2 to 4 As shown, the adjustment structure includes a first connecting hole 210, a second connecting hole 411 and a fastener 710. The first connecting hole 210 is opened in the movable plate 200 along the second horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction. The second connecting hole 411 is opened in the transmission base 400 and is connected to the first connecting hole 210. The fastener 710 is suitable for passing through the first connecting hole 210 and being threadedly connected to the second connecting hole 411. An adjustment gap is formed between the fastener 710 and the first connecting hole 210. When the fastener 710 is tightened, the transmission base 400 and the movable plate 200 are fastened together. When the fastener 710 is loosened, the transmission base 400 can be adjusted relative to the movable plate 200.

[0040] Preferably, at least one first connection hole 210 is arranged at intervals along the vertical direction, and the second connection holes 411 and the fasteners 710 correspond to the first connection holes 210. In this embodiment, there are two first connection holes 210 to simplify the structure while ensuring the stability of the connection between the transmission base 400 and the movable plate 200.

[0041] Furthermore, the movable plate 200 is a long strip structure, and its length direction is parallel to the first horizontal direction. The base 100 is provided with vertical plates 110 on both sides of the first horizontal direction. The vertical plates 110 are provided with slide rail structures arranged along the vertical direction. The two sides of the movable plate 200 are respectively installed on different slide rail structures so that the movable plate 200 can be raised and lowered relative to the base 100.

[0042] The movable plate 200 has a first side 220 and a second side 230 in the second horizontal direction, and the first connection hole 210 passes through from the first side 220 to the second side 230. The transmission seat 400 abuts against the second side 230, and the second connection hole 411 is formed by being recessed inward from the side where the transmission seat 400 abuts against the second side 230. The fastener 710 includes a screw portion 711 and a cap portion 712 connected to one end of the screw portion 711, the screw portion 711 is suitable for passing through the first connection hole 210 from the first side 220 and being threadedly connected to the second connection hole 411, the cap portion 712 is located on the first side 220, and is suitable for abutting against the first side 220 when the fastener 710 is tightened, so as to achieve the fastening of the transmission seat 400 and the movable plate 200.

[0043] However, by adopting the above-mentioned adjustment structure, the transmission seat 400 can be adjusted arbitrarily along the radial direction of the fastener 710. In this embodiment, the movable plate 200 is provided with a guide groove 240 inwardly from the second side 230, and the transmission seat 400 is at least partially embedded in the guide groove 240. The guide groove 240 is suitable for guiding the transmission seat 400 to slide in the vertical direction to ensure that when the fastener 710 is loosened, the transmission seat 400 can be reliably raised and lowered in the vertical direction to avoid positional displacement in other directions. Since the second connecting hole 411 of the transmission seat 400 is blocked by the movable plate 200, it is inconvenient to align the fastener 710 with the second connecting hole 411 during initial assembly. Preferably, when the transmission seat 400 moves downward to the extreme position, the first connecting hole 210 and the second connecting hole 411 are coaxial, so as to facilitate the alignment of the fastener 710 with the second connecting hole 411 during initial assembly.

[0044] Furthermore, the movable plate 200 is provided with a protective groove 250 recessed inward from the first side 220, and the protective groove 250 corresponds one-to-one to the transmission seat 400. The first connecting hole 210 is recessed from the bottom of the protective groove 250, and the cap portion 712 is accommodated in the protective groove 250 to prevent the fastener 710 from protruding relative to the first side 220 of the movable plate 200, so as to effectively protect the fastener 710 and also save installation space.

[0045] Furthermore, since the distance of the transmission seat 400 for adjusting up and down is small, the adjustment of the transmission seat 400 is usually fine-tuned. It is difficult to effectively fine-tune the transmission seat 400 by directly adjusting the transmission seat 400 by hand. Preferably, the transmission seat 400 includes a mounting portion 412 covering the top side of the movable plate 200, and the mounting portion 412 is provided with an adjustment hole 413 in the vertical direction. The adjustment structure includes an adjustment member 720 threadedly connected to the adjustment hole 413, and the bottom of the adjustment member 720 is suitable for gradually extending out of the mounting portion 412 under the rotation operation and pushing against the movable plate 200. When the transmission seat 400 needs to be adjusted, the fastener 710 can be loosened first, and then the adjustment member 720 can be rotated to push against the movable plate 200, thereby driving the transmission seat 400 to gradually move upward, so as to achieve a fine-tuning operation with higher adjustment accuracy.

[0046] In this embodiment, the adjusting member 720 is specifically a flat-head top screw, and its upper end is recessed inward to form an internal hexagonal structure to facilitate docking with a wrench, thereby improving the convenience of rotating the adjusting member 720. In addition, the outer diameter of the adjusting member 720 can be set larger in a limited space, and the contact surface with the top side of the movable plate 200 is larger, thereby improving its pushing effect on the movable plate 200.

[0047] Further, the transmission seat 400 includes a seat body 410 and a transmission member 420. The seat body 410 can be embedded in the guide groove 240 from the notch of the guide groove 240, the second connection hole 411 is formed in the seat body 410, and the mounting portion 412 extends from the seat body 410 toward the side of the movable plate 200 along the second horizontal direction. The portion of the seat body 410 received in the guide groove 240 is block-shaped, and accordingly, the guide groove 240 is a square groove adapted thereto, the seat body 410 is limited by the guide groove 240 in the first horizontal direction, and the seat body 410 is limited by the fastener 710 in the second horizontal direction. When the fastener 710 is loosened, the seat body 410 can only be raised and lowered to adjust the position in the vertical direction.

[0048] Preferably, the guide groove 240 extends upward to the top side of the movable plate 200, and the top of the seat body 410 extends the guide groove 240 upward to avoid hindering the upward movement and adjustment of the transmission seat 400. The transmission member 420 is installed on the top of the seat body 410, and the clamping jaw 600 is located above the transmission seat 400 and is in transmission connection with the transmission member 420. There are two transmission members 420, which are arranged opposite to each other along the first horizontal direction, and the clamping jaw 600 is accommodated between the two transmission members 420.

[0049] Further, refer to Figure 1 and Figure 5As shown, the fixed plate 500 is a long strip structure, the length direction of which is parallel to the first horizontal direction, and the two ends of the fixed plate 500 are respectively fixed to different vertical plates 110. The clamping jaw 600 includes a connecting shaft 610, a clamping member 620 and an elastic member 630. The connecting shaft 610 is fixed to the fixed plate 500 along the second horizontal direction. There are two clamping members 620, and both can be rotatably sleeved on the connecting shaft 610. The elastic member 630 is a spring, which is connected between the two clamping members 620. The clamping member 620 has a clamping portion 621 and a transmission portion 622 located below the clamping portion 621. The two transmission portions 622 are both accommodated between the two transmission members 420, and are suitable for respectively abutting against different transmission members 420 under the action of the elastic member 630. The side of the transmission part 622 that contacts the transmission member 420 is an inclined surface, and the inclined surface gradually inclines from top to bottom in a direction away from the transmission member 420 to guide the transmission part 622 to rotate during the lifting process. Preferably, the transmission member 420 is a round rod whose axis is parallel to the second horizontal direction, and the transmission member 420 is rotatably connected to the seat body 410, so that there is rolling friction between the inclined surface of the transmission part 622 and the transmission member 420, which is smaller than sliding friction, and the transmission part 622 is not easy to wear and rotates more smoothly. The area between the seat body 410 and the corresponding transmission member 420 is provided with an avoidance hole 414 for the transmission part 622 to pass through in the vertical direction, so as to avoid the transmission part 622 when the transmission seat 400 is lifted or lowered.

[0050] Furthermore, the driving member 300 is a conventional linear cylinder, which is arranged in the vertical direction, and its output end is connected to the bottom of the movable plate 200 to drive the movable plate 200 and the multiple transmission seats 400 located thereon to rise and fall. When the transmission seat 400 rises, the transmission member 420 is suitable for pushing the two transmission parts 622 to drive the two clamping parts 621 to rotate in opposite directions and compress the elastic member 630. When the transmission seat 400 descends, the two clamping parts 621 are suitable for rotating toward each other under the rebound of the elastic member 630. When the two clamping parts 621 rotate in opposite directions, they move away from each other to realize the opening of the clamping jaws 600. When the two clamping parts 621 move toward each other, they move closer to each other to realize the closing of the clamping jaws 600.

[0051] Further, the output end of the driving member 300 can move upward to the limit position so that the clamping jaws 600 are in a fully open state, and the output end of the driving member 300 can move downward to the limit position so that the clamping jaws 600 are in a closed state. Preferably, the tail clamp mechanism also includes a limit member 800 installed on the base 100, and the limit member 800 is also a linear cylinder arranged along the vertical direction, and its output end is located directly below the movable plate 200. When the limit member 800 is in the extended state, during the downward movement of the output end of the driving member 300, the movable plate 200 is suitable for abutting against the limit member 800, so that the clamping jaws 600 are in a slightly open state, and when the limit member 800 is in the retracted state, the output end of the driving member 300 can move upward to the limit position or move downward to the limit position.

[0052] The above description is only an implementation method of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the description and drawings of this application, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
