[0022] The utility model discloses a laser welding tool for grille. Figure 2-Figure 5 As shown, it includes a working box 1, which is a component formed by buckling a box body and a box cover. An arcuate slide rail 10 and two first linear slide rails 2 are fixedly installed on the inner bottom of the working box 1. The two first linear slide rails 2 are symmetrically arranged on both sides of the arcuate slide rail 10. Each first linear slide rail 2 is slidably installed with a first slider, and the arcuate slide rail 10 is slidably installed with two second sliders, so that the first slider can perform reciprocating linear motion along the first linear slide rail 2, and the second slider can perform reciprocating arc motion along the arcuate slide rail 10.

When the shift rod 7 is translated along the first linear slide rail 2 through the first slider, the two linear bearings 4 can move along the shift rod 7. At the same time, the rotating seat 3 can compensate for the angle change between the linear bearing 4 and the second slider, thereby realizing the action of simultaneously translating the two support seats 6 and the arc-shaped sheet clamping part 5 through a shift rod 7, and the arc-shaped sheet clamping part 5 is used to clamp the arc-shaped sheet component in the fixed grid.

[0024] A second linear slide 11 is fixedly installed on the upper surface of the working box 1, and a third slider is slidably installed on the second linear slide 11. A support plate is fixedly installed on the upper surface of the third slider, and a straight plate clamping member 9 is provided on the upper side of the support plate. The straight plate clamping member 9 can move back and forth along the second linear slide 11 through the third slider. The straight plate clamping member 9 is used to clamp the straight plate components in the fixed grid.

[0025] A positioning assembly 8 is provided on one side of the straight plate clamping member 9 and one side of the shift rod 7. The side wall of the working box 1 is provided with an avoidance groove for passing the shift rod 7. The positioning assemblies 8 at the two locations are respectively used to position the straight plate clamping member 9 and the arc-shaped sheet clamping member 5 to adapt to the shape of the parts to be welded.

[0026] Specifically, such as Figure 4 As shown, the arc-shaped sheet clamping member 5 includes an outer arc clamping plate 51 and an inner arc clamping plate 52. The outer arc clamping plate 51 and the supporting ear 53 are fixedly installed on the upper surface of the support seat 6. A screw hole is opened at the center of the supporting ear 53, and a bolt 54 is screwed into the screw hole. One end of the bolt 54 is rotatably assembled with the inner arc clamping plate 52. The inner arc clamping plate 52 is slidably installed on the support seat 6 and is located between the outer arc clamping plate 51 and the supporting ear 53; when the adjusting bolt 54 is rotated, the inner arc clamping plate 52 can be translated toward or away from the outer arc clamping plate 51 through the screw connection relationship with the supporting ear 53, thereby completing the action of clamping or loosening the arc-shaped sheet component.

[0027] Specifically, such as Figure 5As shown, the straight plate clamping member 9 includes a U-shaped steel 91, a straight splint 92 and a bidirectional screw module 94. The upper surface of the arc slide 10 is fixedly mounted with a bidirectional screw module 94 and a worm gear reducer 93. The input end of the worm gear reducer 93 is connected to a handwheel, and the output end of the worm gear reducer 93 is connected to the input end of the bidirectional screw module 94. The upper side of the bidirectional screw module 94 is fixedly mounted with a U-shaped steel 91. The bidirectional screw module 94 is provided with two slides and symmetrically arranged on both sides of the U-shaped steel 91. The upper surface of the slide is fixedly mounted It is equipped with a straight clamping plate 92; the bidirectional screw module 94 is an existing device with a shell, a bidirectional threaded screw, two slides and other structures, and the worm gear reducer 93 is an existing device with a reduction box, a worm wheel, a worm and other structures. When the hand wheel is turned, the worm gear reducer 93 can reduce the speed and increase the torque to move the two straight clamping plates 92 in opposite directions (towards or away from each other), completing the clamping action of clamping a pair of straight plate components between the U-shaped steel 91 and the straight clamping plates 92, and the worm gear reducer 93 has reverse braking capability, and is not easy to loosen after clamping.

[0028] Specifically, the positioning assembly 8 includes a hemisphere 81, a handle 83 and a button pin 84. The handle 83 is fixedly installed on one side of the bidirectional screw module 94 and one side of the shift rod 7. The handle 83 is vertically opened with a through hole, and the through hole is plugged with a button pin 84. The lower end of the button pin 84 is fixedly installed with the hemisphere 81, and the button pin 84 is sleeved with a spring 82, which is against the hemisphere 81 and the handle 83; the spring 82 gives the hemisphere 81 a force to move downward, and the hemisphere 81 can be lifted and the spring 82 can be compressed by the button pin 84.

[0029] Specifically, three first positioning holes 12 for inserting the hemispheres 81 are provided on the top of the working box 1. When the hemispheres 81 are respectively inserted into the first positioning holes 12, the straight plate clamping member 9 can be positioned at three different positions.

[0030] A right-angle steel 14 is fixedly installed on the side wall of the working box 1. Three second positioning holes 15 for inserting the hemisphere 81 are opened on the top of the right-angle steel 14. When the hemisphere 81 here is respectively inserted into the first positioning holes 12, the arc-shaped sheet clamping part 5 can be positioned at three different positions.

[0031] Connecting rings are fixedly installed at the four corners of the working box 1, and the connecting rings can be fixed on the workbench of the laser welding machine through a bolt group.

[0032] How this implementation works:

[0033] According to the part to be welded (Type III frame, Type II frame, Type I frame), adjust the insertion position of the upper positioning component 8 and the first positioning hole 12, and adjust the insertion position of the lower positioning component 8 and the second positioning hole 15 to move the straight plate clamping member 9 and the two arc-shaped sheet clamping members 5 to a matching position.

[0034] The two arc-shaped sheet clamping parts 5 are used to clamp and position the arc-shaped sheet component, and the straight plate clamping parts 9 are used to clamp and position the straight plate component. The ends of the arc-shaped sheet component and the straight plate component can be butted together, and the laser welding machine can weld the front and back sides of the butt joint.

[0035] When welding type III and type II frames, both sides of the U-shaped steel 91 are clamped with straight plate components through straight clamps 92, and each arc-shaped sheet clamping member 5 is clamped with an arc-shaped sheet component; when welding type I frame, only one side of the U-shaped steel 91 and one straight clamping member 92 are clamped with straight plate components, and two arc-shaped sheet clamping members 5 are clamped with the same arc-shaped sheet component, which is flexible to use and has high docking accuracy.
