[0003] In the current welding operation of new energy vehicle chassis parts, positioning is a key link to ensure welding quality. However, due to the complex size specifications of the parts, it is difficult for existing welding equipment to quickly adapt to different-sized parts to complete precise positioning, which not only reduces the actual application value of the equipment, but also seriously restricts the overall efficiency of the welding work. Summary of the Invention

Detailed implementation mode

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0038] Refer to Figures 1-14 , a welding device for new energy vehicle chassis parts, including a body 1, a welding robotic arm 2 is fixedly installed on the upper surface of the body 1, a positioning assembly is symmetrically arranged above the body 1, the positioning assembly includes a placing plate 3 and a pressing plate 4, sliding rods 5 are symmetrically and fixedly installed on the upper surface of the placing plate 3, the pressing plate 4 is slidably sleeved on the two sliding rods 5, an electric telescopic rod 6 is fixedly installed on the upper surface of the placing plate 3, and the driving shaft of the electric telescopic rod 6 is fixedly connected to the top of the pressing plate 4 through a U-shaped rod 7.

[0039] An installation groove 8 is opened on one side of the body 1, a telescopic cylinder 9 is fixedly installed in the installation groove 8, an installation block 10 is fixedly installed at the end of the driving shaft of the telescopic cylinder 9, a rectangular opening 11 communicating with the installation groove 8 is horizontally opened on the upper surface of the body 1, and the top end of the installation block 10 is slidably arranged in the rectangular opening 11. The lower surface of one of the placing plates 3 is fixedly connected to the upper surface of the body 1, and the lower surface of the other placing plate 3 is fixedly connected to the top of the installation block 10.

[0040] In the initial state, the distance between the two sets of positioning components is the largest, and the welding robotic arm 2 is also at the highest position. Before welding the components, first place the two components to be welded into the two sets of positioning components respectively and place them on the upper surface of the placing plate 3. Then start the electric telescopic rod 6 and control the pressing plate 4 to move downward until the pressing plate 4 moves downward to tightly abut against the component on the upper surface of the placing plate 3, and the component is pressed and positioned between the pressing plate 4 and the placing plate 3 to complete the positioning. Then start the telescopic cylinder 9 at this time and control one set of positioning components to drive the positioned component to move in the direction close to the other set of positioning components. Until the components positioned by the two sets of positioning components abut against each other, then turn off the telescopic cylinder 9, and then start the welding robotic arm 2 to weld the two abutting components. After the welding is completed, turn off the welding robotic arm 2 and move it to the highest position. Then control the electric telescopic rod 6 on the upper surface of the placing plate 3 fixedly connected to the upper surface of the table body 1 to drive the pressing plate 4 to move upward. After the positioning of the component by this set of positioning components is released, then start the telescopic cylinder 9 to drive the positioning component fixedly connected to the mounting block 10 to move, and the welded component will also move along with it until the distance between the two sets of positioning components is the largest. At this time, then control the other electric telescopic rod 6 to drive the pressing plate 4 to move upward to completely release the positioning of the component, and then it can be removed. With the synergistic effect of the pressing plate 4 and the placing plate 3 in the positioning component, the positioning operation of components of different specifications can be quickly realized, and the process of releasing the positioning is also very convenient. This design not only improves the practical performance of the device but also speeds up the efficiency of the welding operation.

[0041] The upper surface of the pressing plate 4 is provided with a stabilizing component for strengthening the positioning effect of the components. The stabilizing component includes an installation box 12 fixedly installed on the upper surface of the pressing plate 4 through multiple connecting rods and multiple stabilizing rods 13. The bottom of the installation box 12 is provided with a plurality of sliding openings 14, and the multiple stabilizing rods 13 are respectively vertically and slidably and sealingly inserted into the plurality of sliding openings 14. The upper surface of the pressing plate 4 is provided with a plurality of through openings respectively communicating with the plurality of sliding openings 14, and the multiple stabilizing rods 13 are respectively vertically and slidably inserted into the plurality of through openings. One end of the stabilizing rod 13 located inside the installation box 12 is connected to the inner wall of the installation box 12 through a telescopic component. The telescopic component includes a first telescopic spring 18, and the two ends of the first telescopic spring 18 are respectively fixedly connected to the top end of the stabilizing rod 13 and the inner top wall of the installation box 12. One side of the installation box 12 is provided with a through opening, and one side of the installation box 12 is fixedly installed with an installation column 15 covering the through opening. One end of the installation column 15 close to the installation box 12 is provided with an air groove 16, and one end of the installation column 15 far from the installation box 12 is provided with a plurality of ventilation openings 17 in a circumferential shape. One side of the installation box 12 is provided with an opening and closing component for controlling the opening and closing of the plurality of ventilation openings 17. The opening and closing component includes a rotating shaft 19 and a plurality of blocking blocks 20 fixedly installed on the surface of the rotating shaft 19 in a circumferential shape. A rotating opening is provided at the center of one end of the installation column 15 far from the installation box 12, and the rotating shaft 19 is sealingly rotatably installed in the rotating opening. The surfaces of the plurality of blocking blocks 20 are all in sliding sealing contact with the groove wall of the air groove 16 and are respectively used for blocking the plurality of ventilation openings 17. One side of the installation box 12 is fixedly installed with a U-shaped plate 21, and a driving motor 22 is fixedly installed on the surface of the U-shaped plate 21. The output shaft of the driving motor 22 is fixedly connected to the rotating shaft 19. One side of the installation box 12 is provided with a pushing component for controlling the simultaneous upward movement of the plurality of stabilizing rods 13. The pushing component includes a telescopic rod 23 and a push plate 24 fixedly connected to the free end of the telescopic rod 23 through a straight rod. One side of the installation box 12 is fixedly installed with a placement plate, and the telescopic rod 23 is vertically fixedly installed on the lower surface of the placement plate. A plurality of circular openings are provided on the surface of the push plate 24, and the multiple stabilizing rods 13 respectively pass through the plurality of circular openings. A ring 25 is fixedly sleeved on the stabilizing rod 13, and the push plate 24 is located below the ring 25. The diameter of the ring 25 is larger than the diameter of the circular opening.

[0042] In the initial state, multiple stabilizing rods 13 are all at the highest position, and the bottom ends of the stabilizing rods 13 do not penetrate through the through-holes. Multiple first telescopic springs 18 are all in a contracted state. At this time, multiple blocking blocks 20 respectively cover multiple air vents 17, so that multiple air vents 17 are all in a closed state and cannot allow gas to flow through. Therefore, under the action of pressure, multiple stabilizing rods 13 will not move downward under the elastic potential energy of the first telescopic springs 18. When it is necessary to fix the components, place the components on the upper surface of the placing plate 3. After the pressing plate 4 tightly abuts against its surface, the driving motor 22 can be started to control the rotating shaft 19 to drive multiple blocking blocks 20 to rotate until multiple blocking blocks 20 rotate to no longer cover multiple air vents 17. Then, the air vents 17 will be in an open state and allow gas to flow through. At this time, multiple stabilizing rods 13 will move downward under the elastic potential energy of the first telescopic springs 18. The bottom ends of the stabilizing rods 13 corresponding to the components will move downward to abut against the surface of the components, and the bottom ends of the stabilizing rods 13 not corresponding to the components will move downward to abut against the upper surface of the placing plate 3. Then, start the driving motor 22 again to control the rotating shaft 19 to drive multiple blocking blocks 20 to rotate to cover and block multiple air vents 17 again. At this time, multiple air vents 17 are in a closed state again and cannot allow gas to flow through. Therefore, under the action of pressure, the stabilizing rods 13 cannot move upward. When it is necessary to control multiple stabilizing rods 13 to move upward together, first start the driving motor 22 to control the rotating shaft 19 to drive multiple blocking blocks 20 to rotate until multiple blocking blocks 20 rotate to no longer cover multiple air vents 17. At this time, control the push plate 24 to move upward to make the telescopic rod 23 contract. During the upward movement of the push plate 24, its upper surface will gradually abut against the lower surfaces of multiple rings 25 and push multiple rings 25 and multiple stabilizing rods 13 to move upward together. Multiple first telescopic springs 18 will all contract until the upper surfaces of multiple rings 25 all abut against the lower surface of the installation box 12. At this time, multiple stabilizing rods 13 are all at the highest position. Then, start the driving motor 22 at this time to control the rotating shaft 19 to drive multiple blocking blocks 20 to rotate until multiple blocking blocks 20 cover and block multiple air vents 17 again, and then the push plate 24 can be released. The push plate 24 will quickly move downward under the action of gravity, and the telescopic rod 23 will also stretch. At this time, under the action of air pressure, although the push plate 24 no longer gives a thrust to multiple rings 25, multiple stabilizing rods 13 will not move downward.

[0043] Multiple stabilizing rods 13 can improve the positioning effect of the components. At the same time, for the complex contours of irregular components, through the differential contact method of "the bottom end of the stabilizing rod 13 corresponding to the component moves downward to tightly abut against the surface, and the bottom end of the non-corresponding stabilizing rod 13 abuts against the upper surface of the placing plate 3", contour-fitting fixation can be achieved, solving the problem that traditional planar positioning is difficult to adapt to irregular curved surfaces.

[0044] A T-shaped rod 26 is fixedly installed on the surface at the free end of the telescopic rod 23. Anti-slip patterns are provided on the surface of the T-shaped rod 26. Holding the T-shaped rod 26 facilitates controlling the vertical movement of the push plate 24. At the same time, the anti-slip patterns can increase the friction between the palm and the contact surface of the T-shaped rod 26.

[0045] On one side of the table body 1, a first arc-shaped plate 28 is fixedly installed through a support rod 27. The first arc-shaped plate 28 is located above the placing plate 3 fixedly connected to the table body 1. On the side of the table body 1 far from the support rod 27, a mounting ring 30 is fixedly installed through an L-shaped rod 29. A rotating rod 31 is rotatably installed in the mounting ring 30. A second arc-shaped plate 33 is fixedly installed on the surface of the rotating rod 31 through a connecting rod 32. The second arc-shaped plate 33 is located above the placing plate 3 fixedly connected to the mounting block 10. The rotating rod 31 is controlled to rotate through a threaded component. The threaded component includes a threaded rod 34 and a second telescopic spring 35. The lower surface of the threaded rod 34 is fixedly installed with a sliding plate 36. A sliding groove 37 is horizontally opened at the bottom of the installation groove 8. The bottom end of the sliding plate 36 is slidably arranged in the sliding groove 37, and the side wall is in sliding contact with the groove wall of the sliding groove 37. The sliding plate 36 can only move horizontally in the sliding groove 37 and cannot rotate. The two ends of the second telescopic spring 35 are respectively fixedly connected to the surface of the sliding plate 36 and the groove wall of the sliding groove 37. A threaded hole 38 adapted to the thread on the surface of the threaded rod 34 is horizontally opened at the end of the rotating rod 31. One end of the threaded rod 34 is threadedly installed in the threaded hole 38. The threaded rod 34 is located on the moving path of the mounting block 10.

[0046] When positioning the component parts, the welding robotic arm 2 will be at the highest position, and the distance between the two positioning components will be the largest. The mounting block 10 will abut against the threaded rod 34 and apply a pressing force to the threaded rod 34. The second telescopic spring 35 will be in a contracted state. At this time, the first arc-shaped plate 28 and the second arc-shaped plate 33 will be located between the two positioning components and the welding robotic arm 2, thus separating the positioning components from the welding robotic arm 2. Then, the component parts are positioned at this time. After the positioning is completed, the telescopic cylinder 9 drives the mounting block 10 and one of the positioning components to move towards the direction close to the other positioning component. The pressing force applied by the mounting block 10 to the threaded rod 34 will gradually disappear, and the threaded rod 34 will quickly move back to its original position under the elastic potential energy of the second telescopic spring 35. Since the threaded rod 34 cannot rotate, under the action between the thread on the surface of the threaded rod 34 and the threaded hole 38, the rotating rod 31 will drive the connecting rod 32 and the second arc-shaped plate 33 to rotate. The second arc-shaped plate 33 will rotate to no longer be located between the welding robotic arm 2 and the positioning component, facilitating the welding and processing of the component parts by the welding robotic arm 2. Since the space between the two positioning components is the welding station, the first arc-shaped plate 28 located above the non-movable positioning component does not need to rotate. Then, when the welding is completed, at this time, the welding robotic arm 2 will move to the highest position again. Then, after releasing the positioning of the component parts by the non-movable positioning component, the telescopic cylinder 9 is started to drive the movable positioning component and the component parts to move together until the distance between the two positioning components is the largest. At this time, the mounting block 10 will abut against the threaded rod 34 again and push against the threaded rod 34, causing the second telescopic spring 35 to contract. At this time, the rotating rod 31 will drive the second arc-shaped plate 33 to rotate to be located between the welding robotic arm 2 and the positioning component again, separating them, avoiding potential safety hazards such as scalding when the operator's hand needs to be located below the welding robotic arm 2 during the process of placing or taking the component parts.

[0047] Anti-slip pads are bonded to the upper surface of the placing plate 3 and the lower surface of the pressing plate 4. The anti-slip pads are made of rubber. The rubber anti-slip pads have good elasticity and adhesiveness, thus increasing the friction between the placing plate 3 and the pressing plate 4 and the contact surface of the component parts and improving the stability of positioning.

[0048] In the present invention, with the coordinated action of the pressing plate 4 and the placing plate 3 in the positioning component, the positioning operation of component parts with different specifications can be quickly realized, and the process of releasing the positioning is also very convenient. This design not only improves the practical performance of the device but also speeds up the efficiency of the welding operation.

[0049] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
