Description

Technical Field

[0001] The present invention relates to the technical field of air intake grille welding equipment, and in particular to an air intake grille laser welding all-in-one machine with rotary multi-side station switching. Background Art

[0002] The air intake grille is an opening structure at the front of the car used to guide airflow. Its main function is to balance heat dissipation, aerodynamics and aesthetic design. When the car moves forward, it provides air to the engine compartment or cooling system to help dissipate heat.

[0003] The air intake grille is mainly composed of an outer frame and a skeleton. As the car's assisted driving becomes increasingly intelligent, some air intake grilles are also equipped with a radar box for installing a laser radar (such as Figure 11 As shown in the figure), the outer frame of the air intake grille is generally composed of multiple frames. Figure 11 For example, the outer frame shown in the figure is mainly composed of an upper frame and a lower frame. The existing processing process generally uses welding to connect the various components of the air intake grille. Generally, the upper frame and the lower frame are first welded together at the outer frame welding station to form the outer frame. The welded outer frame is then transferred to the skeleton welding station and the radar box welding station, and the skeleton and the radar box are welded to the outer frame in sequence. The above welding process also has the following shortcomings: when welding different components of the air intake grille, each welding station needs to clamp and lock the component to be welded at this station, and each time, one air intake grille is clamped and locked. After each welding step is completed, it needs to be unlocked. The entire welding process of the air intake grille requires multiple locking and unlocking processes, which takes a long time and affects the processing efficiency of the air intake grille. Summary of the Invention

[0006] In one possible implementation, a limiting groove is provided on the top of the slide, and a limiting plug corresponding to the limiting groove is fixedly connected to the bottom of the supporting component 2. When the two corresponding slides collide with each other, the supporting component 2 drives the limiting plug to move downward and engage with the corresponding limiting groove.

[0007] In one possible implementation, the supporting assembly 1 includes a supporting member 1 for supporting and positioning the upper frame and a supporting member 2 for supporting and positioning the lower frame. The supporting member 1 is fixedly mounted on the top of the slide close to the center of the electric turntable, and the supporting member 2 is fixedly mounted on the top of the slide away from the center of the electric turntable. The tops of the supporting member 1 and the supporting member 2 are respectively provided with grooves that are adapted to the outer shapes of the upper frame and the lower frame, and the opposite sides of the supporting member 1 and the supporting member 2 are provided with through grooves for plugging and matching the skeleton, the radar box, and the upper frame and the lower frame.

[0009] In one possible implementation, the clamping assembly includes a plurality of movable grooves provided on the top of the supporting assembly 2 and distributed along its length direction, a clamping block is slidably installed inside the movable groove along the length direction of the supporting assembly 2, a guide groove is provided on the inner wall of the movable groove parallel to the length direction of the supporting assembly 2, a guide block is fixedly connected to the clamping block and slides with the corresponding guide groove, and the bottoms of several of the clamping blocks are commonly fixedly connected to a pull plate located below the supporting assembly 2.

[0010] In one possible implementation, the alignment assembly includes an alignment plate 1 located on the side of the support assembly 2 close to the center of the electric turntable and an alignment plate 2 located on the side of the support assembly 2 away from the center of the electric turntable. The sides of the alignment plate 1 and the alignment plate 2 away from the support assembly 2 are both fixedly connected to support rods. The alignment plate 1 is fixedly connected to the slide close to the center of the electric turntable through the corresponding support rod, and the alignment plate 2 is fixedly connected to the slide away from the center of the electric turntable through the corresponding support rod.

[0011] In a possible implementation, the alignment plate 1 and the alignment plate 2 are distributed parallel to the side wall corresponding to the supporting component 2, and rollers are rotatably installed at the positions of the alignment plate 1 and the alignment plate 2 corresponding to the frame or the radar box.

[0012] In one possible implementation, the lifting assembly includes a gear sleeve that is rotatably installed inside the welding station and symmetrically distributed on both sides of the guide rail. The internal thread of the gear sleeve is connected to a threaded rod. The bottom end of the threaded rod is connected to the welding station for sliding up and down. The top end of the threaded rod is fixedly connected to the bottom of the pull plate. A driving rack corresponding to the gear sleeve is fixedly connected on the slider near the center of the electric turntable. The driving rack is slidably installed inside the welding station along the length direction of the guide rail, and the driving rack is engaged with the corresponding gear sleeve.

[0013] In one possible implementation, a synchronization component is also installed between the corresponding two slides. The synchronization component includes a center gear rotatably installed on the welding station and symmetrically distributed on both sides of the guide rail. The center gear is located between the corresponding two slides. A synchronization rack corresponding to the center gear is fixedly connected to the slide. The two center gears located on the same side of the slide are respectively engaged with the upper and lower sides of the corresponding center gear.

[0014] The beneficial effects of the present invention are as follows: 1. The present invention combines and fixes the outer frame, skeleton and radar box of the air intake grille at the same time through the mutual cooperation of the supporting component 1, the supporting component 2, the pressing component and the alignment component. When the supporting component 1 combines the outer frame together, the alignment component can align the skeleton, and then the lifting component drives the pressing component to press the skeleton and the radar box and push the supporting component 2 to move downward, so that the skeleton and the radar box can be combined with the outer shell, which is convenient for docking the outer frame, skeleton and radar box together at one time, thereby improving the efficiency of the air intake grille welding process.

DETAILED DESCRIPTION

[0028] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described below, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] See also Figure 1 and Figure 2 A rotary multi-side station switching air intake grille laser welding integrated machine includes an electric turntable 1 and several laser welding machines 3 distributed circumferentially about the electric turntable 1. Several welding stations 2 are evenly installed circumferentially on the top of the electric turntable 1. A clamping mechanism 4 for clamping and fixing the outer frame, skeleton and radar box is installed on the top of the welding station 2.

[0030] See also Figure 1 - Figure 6The clamping mechanism 4 includes a slide 41 slidably mounted on the top of the welding station 2 and symmetrically distributed about the center point of the welding station 2. A supporting component 1 42 for supporting and positioning the outer frame is commonly installed on the top of the two slides 41. A moving component 43 for driving the two slides 41 to move synchronously in opposite directions is installed on the welding station 2. A supporting component 2 44 for supporting and limiting the skeleton and the radar box is movably installed on the top of the welding station 2. A mounting slot for inserting the skeleton and the radar box is provided on the supporting component 2 44. A clamping component 45 for fixing the skeleton and the radar box is installed on the supporting component 2 44. An alignment component 46 for aligning the skeleton and the radar box is installed on the top of the slide 41. A lifting component 47 for moving the supporting component 2 44 up and down driven by the moving component 43 is installed on the welding station 2. An elastic telescopic rod 2 48 is fixedly connected between the top of the welding station 2 and the bottom of the supporting component 2 44.

[0031] Specifically, in the initial state, the two slides 41 are in a phase-separated state, and the supporting component 2 44 is located above the center of the welding station 2. The outer frame, skeleton and radar box to be welded are placed on the supporting component 1 42 and the supporting component 2 44 respectively. The elastic telescopic rod 2 48 plays the role of elastic support for the supporting component 2 44, so that the supporting component 2 44 can only move up and down. When combined, the two slides 41 are driven toward each other by the moving component 43 until the two slides 41 collide with each other, so that the supporting component 1 42 connects the upper frame and the lower frame together. While the slide 41 moves, it drives the alignment component 46 to approach the supporting component 2 44, so that the alignment component 46 pushes and aligns the skeleton on the supporting component 2 44 and the end of the radar box. When the upper frame and the lower frame are connected, the moving component 43 drives the pressing component 45 to press and fix the frame and the radar box by driving the lifting component 47, and drives the supporting component 2 44 to move downward after the fixation is completed, so that the ends of the frame and the radar box can be plugged into the upper frame and the lower frame. Finally, the three laser welding machines 3 respectively perform the welding of the upper frame and the lower frame, the welding of the frame and the radar box with the upper frame and the lower frame, and the welding of the radar box with the frame. The electric turntable 1 drives the welding station 2 to rotate to different laser welding machines 3 in turn for welding, which can quickly complete the batch welding of the outer frame, the frame and the radar box, and ...

[0032] See also Figure 3 、 Figure 7 and Figure 10 A limiting groove 411 is provided at the top of the slide 41, and a limiting plug 441 corresponding to the limiting groove 411 is fixedly connected to the bottom of the supporting component 44. When the two corresponding slides 41 conflict with each other, the supporting component 44 drives the limiting plug 441 to move downward and engage with the corresponding limiting groove 411.

[0033] During specific use, after the corresponding two slides 41 collide with each other, the lifting assembly 47 drives the supporting assembly 2 44 to move downward, and the skeleton and the radar box are plugged together with the upper frame and the lower frame. At this time, the supporting assembly 2 44 is pressed against the top of the two slides 41, and the limiting plug 441 at the bottom of the supporting assembly 2 44 is respectively inserted into the limiting groove 411 on the top of the two slides 41, thereby fixing the corresponding two slides 41 together, avoiding the separation of the two slides 41 during the welding process, ensuring the tightness of the combination of the skeleton, radar box, upper frame and lower frame, and avoiding the occurrence of cold welding.

[0034] See also Figure 2 and Figure 3 The supporting component 42 includes a supporting member 421 for supporting and positioning the upper frame and a supporting member 422 for supporting and positioning the lower frame. The supporting member 421 is fixedly mounted on the top of the slide 41 on the side close to the center of the electric turntable 1, and the supporting member 422 is fixedly mounted on the top of the slide 41 on the side away from the center of the electric turntable 1. The tops of the supporting member 421 and the supporting member 422 are respectively provided with grooves that are adapted to the outer shapes of the upper frame and the lower frame, and the ends of the grooves are connected to the outside world. The opposite sides of the supporting member 421 and the supporting member 422 are provided with through grooves for the skeleton, the radar box and the upper frame and the lower frame to be plugged in and matched.

[0035] During specific use, before welding, the upper frame and the lower frame are placed in the grooves on the top of the supporting member 1 421 and the supporting member 2 422 respectively. The ends of the upper frame and the lower frame will be exposed from the ends of the corresponding grooves. The supporting member 1 421 and the supporting member 2 422 can not only support the upper frame and the lower frame respectively, but also play a positioning role to prevent the upper frame and the lower frame from moving at will, which is conducive to precise docking between the upper frame and the lower frame.

[0036] When the two slides 41 move toward each other, supporting member 1 421 and supporting member 2 422 respectively drive the corresponding upper frame and lower frame to approach each other. When the two slides 41 collide with each other, the ends of the upper frame and the lower frame are just docked and combined together. Since the ends of the upper frame and the lower frame are exposed on the surface of supporting member 1 421 and supporting member 2 422, it is convenient for the subsequent laser welding machine 3 to weld the weld between the upper frame and the lower frame. The through grooves on supporting member 1 421 and supporting member 2 422 are for facilitating the plug-in combination of the ends of the skeleton and the radar box with the upper frame or the lower frame, and exposing the welds between the skeleton and the radar box and the upper frame or the lower frame, which is convenient for subsequent welding.

[0037] See also Figure 2 、 Figure 4 and Figure 5The moving assembly 43 includes a guide rail 431 fixedly installed inside the welding station 2, and a bidirectional screw 432 is rotatably installed on the guide rail 431. A driving motor 433 for driving the bidirectional screw 432 to rotate is installed at one end of the guide rail 431, and the output shaft of the driving motor 433 is fixedly connected to the bidirectional screw 432 through a coupling. A symmetrically distributed slider 1 434 and a slider 2 435 are slidably installed on the guide rail 431 along its length direction. The two sliders 435 are located between the two sliders 1 434. The slider 1 434 is threadedly connected to the bidirectional screw 432. A through hole is provided on the slider 2 435 for the bidirectional screw 432 to slide through. An elastic telescopic rod 1 436 is fixedly connected between the slider 1 434 and the corresponding slider 2 435, and the slide 41 is fixedly installed on the top of the corresponding slider 2 435.

[0038] During specific use, when the upper frame, lower frame, frame and radar box need to be fixedly combined, the bidirectional screw 432 is driven to rotate by the driving motor 433, and the bidirectional screw 432 drives the two sliders 1 434 to move toward each other. The slider 1 434 pushes the corresponding slider 2 435 toward the center of the bidirectional screw 432 through the elastic telescopic rod 1 436, and the slider 2 435 is used to drive the corresponding slide 41 to move toward the center of the welding station 2, thereby realizing the opposite movement of the two slides 41, completing the docking combination of the upper frame and the lower frame and the alignment of the frame and the radar box.

[0039] When the two slides 41 collide with each other, the corresponding two sliders 2 435 no longer move toward each other, and then the bidirectional screw 432 continues to drive the slider 1 434 to move toward the center of the bidirectional screw 432. At this time, the elastic telescopic rod 1 436 will be compressed and contracted, and the slider 1 434 will be used to drive the lifting component 47, and then the lifting component 47 drives the clamping component 45 to fix the skeleton and the radar box. After the fixation is completed, the lifting component 47 drives the supporting component 2 44 to move downward, so that the skeleton and the radar box are plugged into and combined with the upper and lower frames.

[0040] See also Figure 2 and Figure 3 The alignment component 46 includes an alignment plate 1 461 located on the side of the supporting component 2 44 close to the center of the electric turntable 1 and an alignment plate 2 462 located on the side of the supporting component 2 44 away from the center of the electric turntable 1. The sides of the alignment plate 1 461 and the alignment plate 2 462 away from the supporting component 2 44 are fixedly connected with a support rod 463. The alignment plate 1 461 is fixedly connected to the slide 41 close to the center of the electric turntable 1 through the corresponding support rod 463, and the alignment plate 2 462 is fixedly connected to the slide 41 away from the center of the electric turntable 1 through the corresponding support rod 463.

[0041] See also Figure 2 and Figure 3The alignment plate 1 461 and the alignment plate 2 462 are distributed parallel to the side wall corresponding to the supporting component 2 44 , and the alignment plate 1 461 and the alignment plate 2 462 are rotatably installed with rollers 464 at their corresponding positions to the frame or the radar box.

[0042] During specific use, after the frame and the radar box are placed in the mounting grooves on the supporting component 2 44, the ends of the frame and the radar box will be exposed on the outside of the supporting component 2 44, which is convenient for the subsequent plug-in cooperation of the frame and the radar box with the upper frame and the lower frame; when the two corresponding slides 41 move toward each other, the slide 41 will drive the corresponding alignment plate 1 461 or alignment plate 2 462 to move together, so that the alignment plate 1 461 and the alignment plate 2 462 gradually approach the supporting component 2 44, and use the alignment plate 1 461 and the alignment plate 2 462 to push and align the ends of the frame and the radar box to avoid unevenness of the frame and the radar box, which is conducive to the subsequent precise docking with the upper frame and the lower frame.

[0043] By arranging rollers 464 on alignment plate 1 461 and alignment plate 2 462, when support component 2 44 drives the frame and radar box to move downward, rollers 464 can roll, reducing the friction between the frame and radar box and alignment plate 1 461 or alignment plate 2 462, so that support component 2 44 can move downward smoothly, avoiding the frame and radar box from being offset due to frictional resistance, and reducing the wear of alignment plate 1 461 and alignment plate 2 462.

[0044] See also Figure 2 、 Figure 6 、 Figure 7 and Figure 8 The clamping assembly 45 includes several movable grooves 451 opened on the top of the supporting assembly 44 and distributed along its length direction. A clamping block 452 is slidably installed inside the movable groove 451 along the length direction of the supporting assembly 44. The clamping block 452 is in an inverted L shape. The movable groove 451 is parallel to the inner wall of the supporting assembly 44 in the length direction and a guide groove 453 is opened. The clamping block 452 is fixedly connected to a guide block 454 that slides with the corresponding guide groove 453. The bottom of several clamping blocks 452 is commonly fixedly connected to a pull plate 455 located below the supporting assembly 44.

[0045] During specific use, the lifting assembly 47 drives the pull plate 455 to move downward, and the pull plate 455 drives the clamping block 452 to move downward. In the process of the clamping block 452 moving downward, the guide groove 453 is used to guide the guide block 454, so that the clamping block 452 moves toward the direction close to the corresponding frame or radar box, so that the horizontal section of the clamping block 452 can be pressed on the corresponding frame or radar box, which is beneficial to fix the frame and radar box, prevent the frame and radar box from moving and welding, and improve the accuracy of the docking of the frame and radar box with the upper and lower frames, as well as the quality of welding.

[0046] See also Figure 6 - Figure 9 The lifting assembly 47 includes a gear sleeve 471 that is rotatably mounted inside the welding station 2 and symmetrically distributed on both sides of the guide rail 431. The internal thread of the gear sleeve 471 is connected to a threaded rod 472. The bottom end of the threaded rod 472 is connected to the welding station 2 for vertical sliding movement. The top end of the threaded rod 472 is fixedly connected to the bottom of the pull plate 455. A driving rack 473 corresponding to the gear sleeve 471 is fixedly connected to the slider 1 434 near the center of the electric turntable 1. The driving rack 473 is slidably mounted inside the welding station 2 along the length of the guide rail 431, and the driving rack 473 is meshed with the corresponding gear sleeve 471. It should be noted that the driving rack 473 is only provided with meshing teeth in the portion close to the corresponding slider 1 434, and is not provided with meshing teeth in the portion away from the corresponding slider 1 434.

[0047] When in use, when the slider 1 434 moves toward the center of the bidirectional lead screw 432, the slider 1 434 on the side close to the center of the electric turntable 1 drives the driving rack 473 to move together. When the slider 1 434 pushes the slider 2 435 to move toward the center of the bidirectional lead screw 432, the part of the driving rack 473 without meshing teeth corresponds to the gear sleeve 471. At this time, the driving rack 473 does not mesh with the gear sleeve 471. When the slider 2 435 stops moving and only the slider 1 434 moves toward the center of the bidirectional lead screw 432, the part of the driving rack 473 with meshing teeth just moves to correspond to the gear sleeve 471. At this time, the driving rack 473 is engaged with the gear sleeve 471, and then as the slider 1 434 continues to move, the driving rack 473 is used to drive the gear sleeve 471 to rotate, so that the gear sleeve 471 drives the threaded rod 472 to move downward, and the threaded rod 472 is used to drive the pull plate 455 to move downward, so that the clamping block 452 presses and fixes the skeleton and the radar box. After the fixation is completed, the clamping block 452 cannot continue to move downward relative to the supporting component 2 44. At this time, the pull plate 455 drives the clamping block 452 and the supporting component 2 44 to move downward together, completing the plug-in combination of the skeleton and the radar box with the upper frame and the lower frame. At this time, the elastic telescopic rod 2 48 is compressed and contracted.

[0048] See also Figure 4 A synchronization assembly 49 is also installed between the corresponding two slides 41. The synchronization assembly 49 includes a center gear 491 rotatably installed on the welding station 2 and symmetrically distributed on both sides of the guide rail 431. The center gear 491 is located between the corresponding two slides 41. A synchronization rack 492 corresponding to the center gear 491 is fixedly connected to the slide 41. The two center gears 491 located on the same side of the slide 41 are respectively engaged with the upper and lower sides of the corresponding center gear 491.

[0049] During specific use, when the two corresponding ones move toward each other, the slide 41 will drive the corresponding synchronous rack 492 to move together. Under the transmission of the same center gear 491, the two synchronous racks 492 will move in opposite directions synchronously, thereby driving the two slides 41 to move in opposite directions synchronously, which can ensure that the two slides 41 drive the upper frame and the lower frame to move accurately toward the center of the welding station 2, avoiding deviation when the upper frame and the lower frame are docked, and at the same time improving the accuracy of the subsequent skeleton and radar box plug-in combination with the upper frame and the lower frame.

[0050] See also Figure 1 - Figure 10 After the air intake grille is welded, the driving motor 433 drives the bidirectional lead screw 432 to rotate in the opposite direction, so that the slider 1 434 moves in the direction away from the center of the bidirectional lead screw 432, and the slider 1 434 drives the driving rack 473 to move in the opposite direction, so that the driving rack 473 drives the gear sleeve 471 to rotate in the opposite direction, thereby driving the threaded rod 472 to move upward, and the threaded rod 472 pushes the pull plate 455 to move upward. At this time, the rebound force of the elastic telescopic rod 2 48 is used to push the supporting assembly 2 44 to move upward, so that the supporting assembly 2 44 drives the welded air intake grille to move upward, so that the air intake grille is separated from the supporting part 1 421 and the supporting part 2 422, and the supporting assembly 2 44 drives the air intake grille to move upward to Alignment plate 1 461 and alignment plate 2 462, then the threaded rod 472 continues to move upward, at this time the pulling plate 455 pushes the clamping block 452 to move upward, and uses the guide groove 453 to guide the guide block 454, so that the clamping block 452 releases the fixation on the air intake grille, at this time the elastic telescopic rod 1 436 returns to its original length, and then the slider 1 434 pulls the slider 2 435 to move away from the center of the bidirectional lead screw 432, so that the slider 2 435 drives the corresponding slide 41 away from the center of the welding station 2, and the slide 41 drives the corresponding alignment plate 1 461 or alignment plate 2 462 away from the supporting assembly 2 44, and finally the welded air intake grille is removed from the supporting assembly 2 44.
