Technical Field
[0001] This invention relates to the field of automatic chain welding technology, and in particular to a chain anti-slip high-precision automatic welding platform. Background Technology
[0002] A circular chain is a type of chain composed of interconnected circular links. Due to its loopless structure, it possesses excellent continuity and stability, and is widely used in industry, agriculture, shipbuilding, and lifting. The links allow for flexible movement, adapting to various complex environments and functioning normally under bending, torsion, and other conditions. It exhibits good fatigue resistance and corrosion resistance, making it particularly suitable for humid and chemical environments. Some metal circular chains, after heat treatment and galvanizing, can have their corrosion resistance and wear resistance effectively improved. After the chain is processed, the gaps in the chain links need to be welded to form a complete chain link, thereby improving the chain's strength and service life. An automatic welding platform is used for this welding process. However, traditional chain welding has some problems. Chains are assembled from individual vertical and horizontal links, which makes it difficult for horizontal links to automatically adjust to a vertical position when welding the gaps, making welding cumbersome. Furthermore, it's inconvenient to clamp and position the chain links during welding, causing them to move around and affecting the welding result. Therefore, a high-precision automatic chain welding platform with anti-slip properties is needed to solve these problems. Summary of the Invention

[0010] Preferably, the guide rod is inserted into the interior of the guide groove, and the guide rod and the guide groove form a guide connection.
[0011] Preferably, an auxiliary structure is provided on one side of the mounting base. The auxiliary structure includes a mounting groove, which is opened inside one side of the mounting base. A ratchet is installed inside the mounting groove. A connecting frame is installed on one side of the fixing frame, and a toothed plate is installed at the bottom end of the connecting frame.
[0012] Preferably, a fixing plate is installed on one side of the mounting base, and a mounting box is installed on one side of the fixing plate. A bevel gear set is installed inside the mounting box. One end of the ratchet is connected to one side of the bevel gear set, and a take-up roller is installed on one end of the bevel gear set.
[0013] Preferably, the bottom end of the toothed plate is provided with a plurality of teeth, and the toothed plate meshes with the ratchet teeth.
[0014] The present invention provides a chain-driven anti-slip high-precision automatic welding platform, the advantages of which are: By incorporating a welding structure, during chain welding, the motor rotates, driving the second bevel gear to rotate. This second bevel gear, in turn, engages with the screw, causing the screw sleeve to rotate. As the screw sleeve rotates, a guide plate is positioned on one side and moves within a guide rail, thus limiting its movement. Consequently, the screw sleeve moves upwards outside the screw. This upward movement pushes the extrusion seat upwards. Because the top of the extrusion seat is angled, it compresses the horizontal chain link to one side, causing it to tilt as it moves upwards. As the extrusion seat continues to move upwards, it makes the horizontal chain link vertical, facilitating welding. Furthermore, since a guide block is provided on one side of the inside of the guide seat, and the angle of the guide block gradually increases from one side to the other, the horizontal chain link is forced to gradually adjust to the vertical during the movement. Combined with the upward extrusion of the extrusion seat, the horizontal chain link becomes vertical when it moves to the welding position. During welding, the horizontal chain link becomes a vertical chain link, which facilitates welding the gap of the chain link and completes the adjustment of the chain link angle. Furthermore, by using clamping blocks and springs, the welding seat can be moved to one side, so that the clamping blocks on one side of the clamping frame first fit against both sides of the vertical chain link, pre-clamping the chain link. As the welding seat continues to move to one side, the spring will contract, and the welding head on one side of the welding seat will fit against the notch of the chain link. Through the combined use of clamping blocks and springs, a pre-clamping operation can be performed when welding the chain link. Furthermore, the design of the clamping block + spring achieves flexible pre-fixation. The core is to use the elastic buffer of the spring to synchronize the clamping action with the welding head, which not only prevents the chain link from shifting but also does not hinder the contact of the welding head. When the clamping block contacts the chain link, the welding head continues to feed. The compression of the spring at the rear end of the clamping block is automatically adjusted according to the actual size of the chain link. At this time, the spring force is converted into clamping force. Through spring selection and control, it can fix the chain link without deforming it. No matter how small the size deviation of the chain link is, the elastic deformation of the spring can compensate for the gap, so that the clamping block always fits the side of the chain link and achieves an adaptive clamping effect. In addition, the front end of the clamping block is designed with a V-groove that matches the arc shape of the chain link, making the clamping more stable and preventing slippage during welding, thus achieving high-precision welding. Furthermore, during welding, the chain links may experience slight displacement due to welding vibration and thermal stress. At this time, the compressed spring continuously provides a stable clamping force, counteracting the loosening caused by vibration. The spring force forms damping, reducing chain link swaying and suppressing deformation caused by thermal expansion. This keeps the clamping force maintaining the posture of the chain links and prevents tilting due to local thermal expansion, making the clamping effect better. Compared with traditional rigid clamping blocks, if there is a deviation from the chain link size, it is easy to cause the chain links to not be clamped tightly or to damage the chain links. The spring buffer can adapt to the deviation through elastic deformation, which is especially suitable for chain links with uneven surfaces, such as semi-finished chain links with burrs, and protects the appearance of the workpiece. By incorporating an auxiliary structure, specifically a toothed plate and ratchet, once a chain link is welded, the motor reverses a predetermined number of turns, causing the fixing frame and extrusion seat to return to their original positions. When the fixing frame returns to its original position, the toothed plate drives the ratchet to rotate. During this rotation, the ratchet, in conjunction with the bevel gear set, drives the winding roller to rotate. The winding roller then winds up the chain, automatically moving another chain link to the welding point when the welding head finishes welding one chain link and returns to its original position for the next welding, thus achieving automatic feeding.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] Please see Figures 1-11 The present invention provides a chain anti-slip high-precision automatic welding platform, including a welding table 1, a control panel 2 and a guide seat 4; A mounting base 3 is installed on the top of the welding table 1, a guide seat 4 is installed on the top of the mounting base 3, a control panel 2 is installed on one side of the top of the welding table 1, and a welding structure 5 is provided on the top of the mounting base 3.

Clamping frames 503 are installed on both sides of one end of the welding base 502. A clamping block 504 is installed on one side of the clamping frame 503. A spring 5012 is installed at the middle position of the clamping frame 503 and the clamping block 504. A guide groove 5014 is opened inside one end of the clamping frame 503. A guide rod 5013 is installed inside the guide groove 5014. One end of the guide rod 5013 is connected to one end of the clamping block 504. A through groove 7 is provided in the middle of the interior of the mounting base 3. A fixed plate 5020 is installed at the top of the through groove 7. A second bevel gear 508 is installed at the bottom of the through groove 7. First bevel gears 507 are installed on both sides of the second bevel gear 508. A lead screw 505 is installed at one end of the first bevel gear 507. A threaded sleeve 506 is installed on the outside of the lead screw 505. The top of the threaded sleeve 506 is connected to the bottom of the fixed frame 501. A screw 5011 is installed at the top of the second bevel gear 508. A threaded sleeve 5016 is sleeved on the outside of the screw 5011. A guide rail 5017 is installed on one side of the top of the fixed plate 5020. An extrusion seat 5018 is installed at the top of the threaded sleeve 5016. A groove 5019 is provided inside the top of the extrusion seat 5018. A guide inclined block 5010 is installed on one side of the interior of the guide seat 4. A motor 509 is installed at the bottom of the second bevel gear 508. The two ends of the spring 5012 are fixed to one side of the clamping frame 503 and one side of the clamping block 504, respectively, and the spring 5012 and the clamping block 504 form a telescopic structure. Two sets of clamping blocks 504 are provided, and the two sets of clamping blocks 504 are symmetrically distributed on one side of the welding seat 502; The guide plate on one side of the threaded sleeve 5016 is inserted into the interior of the guide rail 5017, and the threaded sleeve 5016 and the guide rail 5017 form a guide connection. The inner side of the threaded sleeve 5016 is provided with an internal thread, and the outer side of the screw 5011 is provided with an external thread, forming a threaded connection between the threaded sleeve 5016 and the screw 5011. The guide rod 5013 is inserted into the guide groove 5014, and the guide rod 5013 and the guide groove 5014 form a guide connection.
[0020] Specifically, in this embodiment, when welding the chain, the chain is placed inside the guide seat 4. After placement, the external power supply starts the motor 509. Through a pre-designed program, the motor 509 rotates a set number of times. When the motor 509 rotates, it drives the second bevel gear 508 to rotate. When the second bevel gear 508 rotates, it drives the screw 5011 to rotate. During the rotation of the screw 5011, it drives the threaded sleeve 5016 to rotate. During the rotation of the threaded sleeve 5016, because a guide plate is provided on one side of the threaded sleeve 5016 and the guide plate moves inside the guide rail 5017 and is limited by the guide rail 5017, the threaded sleeve 5016 will move upward outside the screw 5011. During the upward movement of the threaded sleeve 5016, it will push the extrusion seat 5018 to move upward. The top of the pressing seat 5018 is inclined, so as the pressing seat 5018 moves upward, it will press the horizontal chain link to tilt to one side. As the pressing seat 5018 continues to move upward, it will make the horizontal chain link become vertical. Since the guide block 5010 is provided on one side inside the guide seat 4, and the angle of the guide block 5010 gradually increases from one side to the other, it forces the horizontal chain link to gradually adjust to vertical during the movement. Combined with the upward pressing of the pressing seat 5018, the horizontal chain link becomes vertical when it moves to the welding position. This makes it easier to weld the notch of the chain link and complete the adjustment of the chain link angle. The groove 5019 is provided so that the pressing seat 5018 does not affect the welding of the welding head 5015 after adjusting the chain link angle. As the second bevel gear 508 rotates, it simultaneously drives the two sets of first bevel gears 507 to rotate. The first bevel gears 507, in turn, drive the lead screw 505 to rotate. The lead screw 505, through its interaction with the lead sleeve 506, causes the fixing frame 501 to move to one side. This movement pushes the welding seat 502 to the side, causing the clamping block 504 on one side of the clamping frame 503 to first engage with both sides of the vertical chain link, pre-clamping the chain link. As the welding seat 502 continues to move to one side, the spring 5012 contracts, causing the welding head 5015 on one side of the welding seat 502 to engage with the notch in the chain link. Through the coordinated use of the clamping block 504 and the spring 5012, pre-clamping can be performed during chain link welding. The design of clamping block 504 + spring 5012 achieves flexible pre-fixation. The core is to use the elastic buffer of spring 5012 to synchronize the clamping action with welding head 5015, which avoids chain link displacement and does not hinder the contact of welding head 5015. When clamping block 504 contacts chain link, welding head 5015 continues to feed. The compression of spring 5012 at the rear end of clamping block 504 is automatically adjusted according to the actual size of chain link. At this time, the elastic force of spring 5012 is converted into clamping force. Through the selection and control of spring 5012, it can fix chain link without deforming it. No matter how small the size deviation of chain link, the elastic deformation of spring 5012 can compensate for the gap, so that clamping block 504 always fits the side of chain link, achieving self-adaptive clamping effect. In addition, the front end of clamping block 504 is designed with a V-groove that matches the arc shape of chain link, making the clamping more stable during clamping. Furthermore, during welding, the chain links may experience slight displacement due to welding vibration and thermal stress. At this time, the compressed spring 5012 continuously provides a stable clamping force to counteract the loosening caused by vibration. The elastic force of the spring 5012 forms damping, reducing chain link swaying and suppressing deformation caused by thermal expansion. This keeps the clamping force maintaining the posture of the chain links and prevents tilting due to local thermal expansion, resulting in better clamping performance. Compared to traditional rigid clamping blocks, which are prone to loosening or damaging the chain links if there is a deviation in size, the spring 5012 buffer can adapt to the deviation through elastic deformation. It is especially suitable for chain links with uneven surfaces, such as semi-finished chain links with burrs, protecting the appearance of the workpiece. After the chain links are clamped, the welding head 5015 is activated to perform an automatic welding operation on the gaps in the chain links.
[0021] See Figures 1-11 An auxiliary structure 6 is provided on one side of the mounting base 3. The auxiliary structure 6 includes a mounting groove 607. The mounting groove 607 is opened inside one side of the mounting base 3. A ratchet 603 is installed inside the mounting groove 607. A connecting frame 605 is installed on one side of the fixing bracket 501. A toothed plate 604 is installed at the bottom end of the connecting frame 605. A fixing plate 601 is installed on one side of the mounting base 3, and a mounting box 602 is installed on one side of the fixing plate 601. A bevel gear set 606 is installed inside the mounting box 602. One end of the ratchet 603 is connected to one side of the bevel gear set 606, and a take-up roller 608 is installed on one end of the bevel gear set 606. The bottom end of the toothed plate 604 is provided with several teeth, and the toothed plate 604 meshes with the ratchet 603.
[0022] Specifically, in this embodiment, after one chain link is welded, the motor 509 reverses the set number of turns, causing the fixing frame 501 and the pressing seat 5018 to return to their original positions. During welding, when the fixing frame 501 moves to one side, it will drive the connecting frame 605 to move to one side. When the connecting frame 605 moves to one side, it will drive the toothed plate 604 to move. When the toothed plate 604 moves to one side, it will drive the ratchet 603 to rotate freely. When the welding is completed and the fixing frame 501 returns to its original position, it will cause the toothed plate 604 to drive the ratchet 603 to rotate. During the rotation of the ratchet 603, it will drive the bevel gear set 606 to rotate. During the rotation of the bevel gear set 606, it will drive the winding roller 608 to rotate. During the rotation of the winding roller 608, the chain will be wound up. This achieves the effect of automatic feeding when the welding head 5015 returns to its original position after welding one chain link, automatically driving another chain link to the welding point, thereby completing the automatic feeding effect and completing the automatic welding of the chain.
