[0019] Next, the technical solutions in the embodiments of the present invention will be described clearly and completely. For the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment 1: Please refer to Figures 1 - 12 , an automatic welding device for welding processing of parts, including a support frame 1 and a welding workbench 2 welded on the top thereof; wherein installation positioning threaded grooves 21 are equidistantly arranged on the top of the welding workbench 2, and the installation positioning threaded grooves 21 are connected to the welding positioning mechanism. A welding manipulator device is placed beside the welding workbench 2 for welding the parts on the welding workbench 2.

[0021] During actual welding operation, for welding work that requires placing the chain horizontally on the welding workbench 2, that is, the limit sleeve in the chain is parallel to the welding workbench 2. Refer to the attached Figure 2As shown, the chain includes outer side link plates 8, inner side link plates 9 and limit sleeves 10. The outer side link plates 8 and the inner side link plates 9 are horizontally placed, and the limit sleeves 10 connected thereto are in a horizontal state. During the process of welding plate-shaped components on the outer side of the outer side link plates 8 of the chain, the side wall of the chain is clamped and positioned by the first welding positioning assembly. First, the extrusion screw 402 is rotated by the second handle 403 so that one end of the extrusion screw 402 clamps and positions the side wall of the chain. When the chain is placed on the welding workbench 2, the two ends of the chain 2 are first tightened, and then clamped and positioned by the symmetrically arranged extrusion screws 402. That is, the welding positioning mechanism includes a first welding positioning assembly, a second welding positioning assembly and a third welding positioning assembly. Through grooves 303 are symmetrically penetrated in the carrier 301 of the first welding positioning assembly, and the carrier 301 is positioned by the installed screws 304. One end of the installed screw 304 is fixedly provided with a first handle 305. The fastening structure includes an extrusion screw 402. The extrusion screw 402 is threadedly connected through and arranged in the extension plate body 401. The extension plate bodies 401 are symmetrically fixed on both sides of one end of the carrier 301. One end of the extrusion screw 402 is fixedly provided with a second handle 403.

[0022] After the chain body is positioned, then the plate-shaped component is placed in the placement groove 302 on the carrier 301. Then the push-press positioning screw 306 is rotated so that one end of the push-press positioning screw 306 pushes the plate-shaped component. At this time, the plate-shaped component will move along the placement groove 302 until one end of the plate-shaped component contacts the side wall of the outer side link plate 8. Then the push-press positioning screw 306 is tightened. During this process, on the one hand, the chain body is fixed first, and then one end of the plate-shaped component is made to be in close contact with the side wall of the chain. Then welding processing is carried out by the welding manipulator device. A placement groove 302 is provided on the top of the carrier 301. The push-press positioning screw 306 is horizontally penetrated and threadedly connected in the carrier 301, and one end of the push-press positioning screw 306 extends into the placement groove 302. The other end of the push-press positioning screw 306 is fixedly provided with an elbow handle 307.

[0023] Embodiment 2: On the basis of Embodiment 1, please refer to Figures 5 - 6When the chain needs to be placed vertically, that is, when one side of the chain needs to be welded, the outer chain plate 8 on one side of the chain is in contact with the welding workbench 2, and the outer chain plate 8 on the other side corresponding to it is directly above it, so that the limiting sleeve 10 in the chain is perpendicular to the welding workbench 2. At this time, the chain is fixed by the second welding positioning assembly, that is, the driving threaded column 504 is rotated by the third handle 505, so that the driving threaded column 504 pushes the positioning clamping plate 508 to clamp and position the limiting sleeve in the chain; the fixing plate body 501 in the second welding positioning assembly is symmetrically provided with mounting holes 502, and the fixing plate body 501 is fixed to the welding workbench 2 by screws, that is, the screws pass through the mounting holes 502 on the fixing plate body 501, and are engaged with the mounting positioning threaded grooves 21 on the welding workbench 2. The fixed plate 501 is connected and fixed, and the symmetrical mounting holes 502 on the fixed plate body 501 are aligned with two adjacent mounting positioning thread grooves 21 on the welding workbench 2, and then screws are used for installation and fixing. The fixed plate body 501 is parallel to the length direction of the welding workbench 2; and a vertical support plate 503 is fixedly provided on the top of the fixed plate body 501, and a driving thread column 504 is threadedly connected through the vertical support plate 503; a third handle 505 is fixedly provided on one end of the driving thread column 504, and an auxiliary bearing 506 is sleeved on the other end of the driving thread column 504, and the auxiliary bearing 506 is embedded in the extension boss 507, and the extension boss 507 is fixedly connected to the positioning clamping plate 508; the positioning clamping plate 508 is set as an arc plate, and the extension boss 507 is fixedly set in the middle position of the outer side wall of the positioning clamping plate 508.

[0024] In actual operation, when the driving threaded column 504 is rotated by the third handle 505, and the driving threaded column 504 then pushes the positioning clamping plate 508, when the positioning clamping plate 508 is about to reach the position of the limiting sleeve 10 in the chain, in order to ensure that the positioning clamping plate 508 and the limiting sleeve 10 are stably fitted, one hand is required to adjust the position of the positioning clamping plate 508 so that the inner side wall of the positioning clamping plate 508 is aligned with the limiting sleeve 10 until the inner side wall of the positioning clamping plate 508 is in contact and fit with the side wall of the limiting sleeve 10, and the positioning clamping plate 508 is set to an arc-shaped plate, the inner side of which can be adapted to fit with the side wall of the limiting sleeve 10, and then continue to tighten the driving threaded column 504, the positioning clamping plate 508 clamps the limiting sleeve 10, thereby realizing the clamping and positioning of the chain.

[0025] Example 3: Based on Example 2, please refer to Figures 7 - 12, when butt welding the end connectors 11 of the chain, after clamping and positioning the chain, specifically, after clamping and fixing the chain with the clamping screw 606, in order to improve the contact tightness between the end connectors 11 of the chain that need to be butt welded, this solution also has an auxiliary structure arranged on the top of the support body 605, making the welding of the end connectors 11 of the chain more firm during the welding operation. Among them, the third welding positioning component is used for clamping and auxiliary welding. Through the combined use of the clamping screw 606 and the auxiliary structure, the chain is clamped and positioned. Both ends of the connecting plate body 601 in the third welding positioning component are symmetrically and fixedly provided with mounting feet 602. The mounting feet 602 are fixed by screws. A limiting chute 603 is arranged through the connecting plate body 601, and a limiting slider 604 is slidably arranged in the limiting chute 603 in a matching manner. The notch shape of the limiting chute 603 is set as a convex shape. The limiting slider 604 is fixedly arranged at the bottom end of the support body 605. A clamping screw 606 is threadedly connected in the support body 605, and a fourth handle 607 is fixedly arranged at one end of the clamping screw 606.

[0026] Among them, the horizontal extension plate 701 in the auxiliary structure is fixedly arranged on one side of the top end of the support body 605, and a vertical extension body 702 is fixedly arranged at the top of one side of the horizontal extension plate 701. A docking slot 703 is arranged at the middle position of the top of the vertical extension body 702. Both ends of the internally threaded tension sleeve 706 are symmetrically and threadedly connected with connecting threaded columns 705 in a matching manner. And the thread rotation directions at both ends of the internally threaded tension sleeve 706 are opposite here, that is, one end is left-handed and the other end is right-handed, forming a vertical threaded channel. When the internally threaded tension sleeve 706 is rotated clockwise or counterclockwise, the connecting threaded columns 705 threadedly connected to its two ends can be simultaneously retracted or extended outwards. One end of the connecting threaded column 705 is fixedly provided with a docking plug 704, and the bottom end of the docking plug 704 is inserted into the docking slot 703 in a matching manner. That is, after clamping the chain, then connect the internally threaded tension sleeve 706 with the connecting threaded columns 705. That is, two connecting threaded columns 705 are symmetrically arranged at both ends of the internally threaded tension sleeve 706. When rotating the internally threaded tension sleeve 706, the connecting threaded columns 705 at both ends of the internally threaded tension sleeve 706 are simultaneously retracted or extended. After adjusting the position of the docking plug 704, insert the docking plug 704 into the docking slot 703 on the vertical extension body 702, and then rotate the internally threaded tension sleeve 706 to make the connecting threaded columns 705 at its two ends retract towards the internally threaded tension sleeve 706. It has a tensioning effect relative to the two support bodies 605, and thus also has a close contact effect on the docking position of the chain welding.
