DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0030] like Figure 1-10 As shown, an embodiment of the present application provides a loading mechanism and a laser welding machine, comprising:

[0031] The bearing seat 1 has a top portion serving as a bearing surface, two movable plates 2 are symmetrically mounted vertically for sliding movement on the bearing seat 1, a stop bar 3 is mounted between the two movable plates 2, and a splint 4 is mounted horizontally for sliding movement on the bearing seat 1;

[0032] A locking member 7 is mounted on the bearing seat 1, and the locking member 7 is used to release the limit or limit the movement of the movable plate 2;

[0033] The limiting mechanism 8 includes a plurality of positioning members 801, which are detachably mounted on the supporting seat 1. A linkage assembly 802 is slidably mounted on the supporting seat 1. When the movable plate 2 moves, the linkage assembly 802 moves at the same time. The linkage assembly 802 is detachably connected to the positioning member 801. That is to say, when in use, the object to be welded must first be placed on the supporting surface of the supporting seat 1, and then one side of the object to be welded must be attached to the blocking rod 3. If the blocking rod 3 blocks the welding position of the object to be welded during subsequent welding, the blocking rod 3 can be moved. After the blocking rod 3 is moved, the position of the movable plate 2 is limited by the locking member 7, thereby temporarily Grounding is used to limit the position of the movable plate 2. After the weld is placed, the clamp 4 is moved so that the weld is clamped between the clamp 4 and the blocking rod 3. If the weld needs to be processed repeatedly in the future, the positioning member 801 can be installed on the support seat 1, and then the positioning member 801 is connected to the linkage assembly 802. When the weld is clamped again next time, the linkage assembly 802 will also move when the clamp 4 is moved until the linkage assembly 802 can be connected to the positioning member 801, indicating that the position of the clamp 4 is now correct, thereby realizing rapid clamping of the weld, which is more convenient for small-batch multi-type welding.

[0034] like Figure 5 and Figure 9 As shown, in some embodiments, the linkage assembly 802 includes a threaded rod 8021 rotatably mounted on the bearing seat 1, a splint 4 is threadedly sleeved on the threaded rod 8021, a guide rod 8022 is mounted on the bearing seat 1, the splint 4 is slidably sleeved on the guide rod 8022, a first synchronous wheel 8023 is rotatably sleeved on the guide rod 8022, and a second synchronous wheel 8023 is fixedly sleeved on the threaded rod 8021.

[0035] 8024, a synchronous belt 8025 is installed between the first synchronous wheel 8023 and the second synchronous wheel 8024, and a connecting plate 8026 is installed on the synchronous belt 8025, and the connecting plate 8026 is detachably connected to the positioning member 801. That is to say, when the connecting plate 8026 moves, the synchronous belt 8025 will be driven to move. Because the synchronous belt 8025 is installed between the first synchronous wheel 8023 and the second synchronous wheel 8024, and the second synchronous wheel 8024 is fixed on the threaded rod 8021, the threaded rod 8021 will rotate at this time. Because the threaded rod 8021 is threadedly matched with the splint 4, the splint 4 will also move at this time. Therefore, when the connecting plate 8026 is moved, the splint 4 will also move at the same time. The position of the splint 4 is indirectly positioned by the detachable connection between the positioning member 801 and the connecting plate 8026. Next time, you only need to move the connecting plate 8026 to the corresponding positioning member 801 to achieve rapid movement of the splint 4.

[0036] like Figure 5 and Figure 9As shown, in some embodiments, the positioning member 801 includes a convex plate 8011 horizontally mounted on one side of the supporting seat 1, a card slot 8012 is opened on one side of the convex plate 8011, the card slot 8012 is T-shaped and both ends pass through the two end surfaces of the convex plate 8011, and further includes a limit seat 8013 slidably inserted in the card slot 8012, the limit seat 8013 is installed with a limiting member 6 for limiting the movement of the limit seat 8013, the connecting plate 8026 is located above the convex plate 8011 and is installed with a mounting tube 8014, a positioning rod 8015 is vertically slidably installed at the bottom end of the mounting tube 8014, and a horizontal structure is formed on the mounting tube 8014. There is a toggle plate 8016 located on the outside, and a plug-in hole 8017 is provided at the top of the limit seat 8013, which is used for inserting the positioning rod 8015. That is to say, when the splint 4 is moved and the position at this time needs to be recorded, the limit seat 8013 is first slid and inserted into the slot 8012 so that the limit seat 8013 is located below the connecting plate 8026, and then the positioning rod 8015 is moved downward so that the positioning rod 8015 is inserted into the plug-in hole 8017 at the top of the limit seat 8013, thereby completing the preliminary fixation, and then the position of the limit seat 8013 can be limited by the limiting member 6.

[0037] like Figure 5 and Figure 9 As shown, in some embodiments, the limiting member 6 includes a sliding plate 601 vertically slidably mounted on a limiting seat 8013, the sliding plate 601 has a horizontal section 602, a fixed gear 603 is configured on the horizontal section 602, a positioning rack 604 is horizontally configured at the bottom end of the protruding plate 8011, and is used to engage with the fixed gear 603, a connecting cylinder 605 is installed on the limiting seat 8013, a connecting rod 606 is vertically slidably mounted on the connecting cylinder 605, the connecting rod 606 is connected to the sliding plate 601, and a connecting spring 607 is installed between the connecting rod 606 and the connecting cylinder 605, that is, When the limit seat 8013 is slid into the slot 8012, the sliding plate 601 is pulled so that the fixed gear 603 is not engaged with the positioning rack 604, and the fixed gear 603 cannot rotate. When the limit seat 8013 is moved, the sliding plate 601 is released, and the elastic deformation characteristics of the connecting spring 607 will cause the fixed gear 603 to engage with the positioning rack 604. Because the fixed gear 603 cannot rotate, when the fixed gear 603 is engaged with the positioning rack 604, the limit seat 8013 cannot move at this time, thereby achieving the positioning of the limit seat 8013.

[0038] like Figure 1 、 Figure 2 and Figure 10As shown, in some embodiments, the locking member 7 includes a sleeve 701 vertically installed on the supporting seat 1, the movable plate 2 is slidably inserted in the sleeve 701, a cylinder 702 is installed on one side of the sleeve 701, and a rod 703 is horizontally slidably inserted on the cylinder 702, and a tightening spring 704 is installed between the rod 703 and the cylinder 702. A plurality of positioning holes 705 are vertically opened on one of the movable plates 2, and the rod 703 is used to be inserted into the positioning hole 705. That is to say, when the movable plate 2 is moved, it is only necessary to move the rod 703 and insert the rod 703 into the corresponding positioning hole 705 of the movable plate 2, thereby indirectly achieving the locking of the height of the blocking rod 3, and the design of the tightening spring 704 effectively prevents the rod 703 from accidentally shaking out of the positioning hole 705.

[0039] like Figure 6 As shown, in some embodiments, the splint 4 includes a sleeve plate 401 with an open top and one side, a movable sub-plate 402 is vertically slidably installed on the sleeve plate 401, and a driving member 403 for driving the movable sub-plate 402 to move is installed on the sleeve plate 401. That is to say, the height of the splint 4 can be changed, so that welding objects of different heights can be performed, thereby improving applicability.

[0040] like Figure 2 and Figure 4 As shown, in some embodiments, the driving member 403 includes two mounting plates 404 installed on one side of the sleeve plate 401, and an adjusting screw 405 is rotatably installed between the two mounting plates 404. A driving block 406 is constructed on the movable sub-plate 402, and the driving block 406 is threadedly sleeved on the adjusting screw 405. That is to say, when the adjusting screw 405 is rotated, because the adjusting screw 405 and the driving block 406 are threadedly matched, the rotation of the adjusting screw 405 will drive the driving block 406 to move, thereby realizing the movement of the movable sub-plate 402, and the threaded matching is self-locking, and the movable sub-plate 402 after moving is not easy to fall down by itself due to external collisions.

[0041] like Figure 3 and Figure 8As shown, a laser welding machine includes the above-mentioned loading mechanism, including a connecting base 9, which is used to connect to the supporting base 1. An electric slide 10 is installed on the top of the connecting base 9, and an electric slide 11 is slidably installed on the electric slide 10. A first manual slide 12 is vertically slidably installed on the top of the electric slide 11. A second manual slide 13 is horizontally slidably installed on the first manual slide 12. A rotating base 14 is rotatably installed on the second manual slide 13. An arc groove 15 is opened through the rotating base 14. An adjusting bolt 16 is screwed into the second manual slide 13. The adjusting bolt 16 passes through the arc groove 15. A laser welding head 5 is installed on the rotating base 14. The entire platform is an automatic welding platform that can weld straight seams of air ducts, joints between air ducts and flanges, air duct plugs, straight seam boxes, and joints between plates. A positioner can be added to weld circular welds. When processing and welding plates with thicknesses of 0.75 to 5.0, the welding length can be extended to a maximum of 1.5 meters at a time. The standard section is 1.25 meters.
