[0020] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Usually, the components of the embodiments of the present application described and marked in the attached drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the attached drawings is not intended to limit the scope of the present application to be protected, but only represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.
[0021] A laser cutting jig for an automobile bumper disclosed by the present utility model is mainly applied to the scenario where when using a traditional laser cutting jig for an automobile bumper, the bumpers of different vehicle models are different, and after being supported by the jig, the bumper needs to be fixed. If the fixation is unstable, it will cause the flatness of the bumper to be not high when laser cutting round holes, and the subsequent use effect is not good.
[0022] Refer to Figure 1 、 Figure 2 and Figure 3 , a laser cutting jig for an automobile bumper, including a workbench 1 and a base 2, further including:
[0023] Limiting mechanism: used to limit the workbench 1 and the base 2;
[0024] A support mechanism is provided on the base 2, a connecting frame 4 is provided on the support mechanism, two first jigs 8 symmetrically distributed are provided on one outer wall of the connecting frame 4, two second jigs 9 are respectively provided on both outer walls at the central position of the connecting frame 4, a connecting platform 10 is fixedly connected to the outer wall of the connecting frame 4 away from the first jig 8, three third jigs 11 are provided on both sides of the top outer wall of the connecting platform 10, two mounting blocks are fixedly connected to one outer wall of the connecting platform 10, a cylinder 12 is provided on the top outer wall of the mounting block, a connecting block 13 is provided at one end of the piston rod of the cylinder 12, and two fitting blocks 14 are provided on both sides of the top outer wall of the connecting block 13. A connecting plate 15 is hinged on the opposite outer walls of the two fitting blocks 14, and a pressing plate 16 is provided on one outer wall of the connecting plate 15.
[0025] In the specific working process, the bumper is placed on the connecting frame 4. The first jig 8, the second jig 9 and the third jig 11 support and position the bumper at the front, back, left, right and central positions. The three are adapted to the placement position of the bumper. Then, by the operation of the cylinder 12, the fitting block 14 is driven to move, and further the pressing plate 16 is driven to move to the fitting position for fixing the bumper. The pressing plate 16 fixes the bumper pneumatically on both sides, making the bumper fixed stably, with high flatness during subsequent laser cutting of round holes, and better use effect of the bumper.
[0026] Among them, the first jig 8, the second jig 9 and the third jig 11 are used in cooperation. In this way, the first jig 8 is located at both positions on the same side of the connecting frame 4, the second jig 9 is located at the middle position of the connecting frame 4, and the third jig 11 is located at both positions on the other side of the connecting frame 4. When the bumper is placed on the connecting frame 4, the middle, front, back, left and right of the bumper can be supported. The jig is positioned to adapt to the shape of the bumper, with stable support and better positioning effect.
[0027] Among them, a rubber pad 17 is provided on the top outer wall of the pressing plate 16, and the cylinder 12 is used in cooperation with the pressing plate 16. In this way, the rubber pad 17 can increase the friction force. When the pressing plate 16 fixes the bumper, the rubber pad 17 can deform, increasing the friction with the bumper and making the fixation tighter. The operation of the cylinder 12 can drive the pressing plate 16 to move up and down, and further adapt to the fixing position of the bumper, with good cooperation effect.
[0028] Refer to Figure 1 and Figure 2 In a preferred embodiment, the support mechanism includes two connecting boxes 3 provided on the top outer wall of the base 2. Two connecting holes are opened on the top outer wall of the connecting box 3. A support rod 7 is provided on the inner wall of the connecting hole. The tops of the four support rods 7 are connected to a connecting frame 4. A support seat 5 is provided on the top outer wall of the base 2. The support seat 5 is located between the two connecting boxes 3. The support seat 5 is connected to one outer wall of the connecting frame 4.
[0029] Specifically, four support rods 7 fixedly support the connecting frame 4, and the support base 5 is supported and fixed at the front side position of the connecting frame 4, so that the connecting frame 4 is stably supported and the subsequent working process is not affected.
[0030] Referring to Figure 1 、 Figure 2 and Figure 4 In a preferred embodiment, the limiting mechanism includes four limiting grooves respectively opened on the outer wall of the top of the base 2 near the four corners, handles 6 are fixedly connected to the four corners of the outer wall of the top of the base 2, two fixing blocks 19 are fixedly connected to the outer walls on both sides of the workbench 1, a fixing plate 20 is hinged to the inner wall of the top of the fixing block 19, four limiting holes 18 are opened on the outer wall of the top of the fixing plate 20, a limiting bolt 21 is arranged on the inner wall of the limiting hole 18, and the limiting bolt 21 passes through the limiting hole 18 and is connected to the inner wall of the limiting groove.
[0031] Specifically, place the base 2 on the workbench 1, move the fixing plate 20 to make the fixing plate 20 lie flat on the top of the base 2, align the limiting holes 18 with the limiting grooves, and then limit the limiting holes 18 and the limiting grooves through the limiting bolts 21 to limit and install the base 2 and the workbench 1. Fixing at the four corners of the workbench 1 is more stable. After the work is completed, the limit of the limiting bolt 21 can be released, and the entire base 2 can be picked up, moved or replaced through the handles 6 at the four corners of the base 2.
[0032] Among them, the positions of the limiting holes 18 correspond to the positions of the limiting grooves, and the limiting bolts 21 are all adapted to the limiting holes 18 and the limiting grooves. In this way, the limiting holes 18 and the limiting grooves can be limited and fixed through the limiting bolts 21 to fix the base 2 and the workbench 1. Fixing is carried out from the positions near the four corners of the workbench 1, so that the four sides of the base 2 are all subjected to the limiting effect and the fixing is more stable.
[0033] Working principle: When in use, place the base 2 on the workbench 1, move the fixing plate 20 to align the limiting holes 18 with the limiting grooves, and then limit and fix the limiting holes 18 and the limiting grooves through the limiting bolts 21 to stably fix between the base 2 and the workbench 1. Then place the bumper on the connecting frame 4, and the first fixture 8, the second fixture 9 and the third fixture 11 support and position the bumper at the front, rear, left, right and middle positions. Then, through the operation of the cylinder 12, the matching block 14 is driven to move up and down, and further the pressing plate 16 is driven to move to the matching position for fixing the bumper. The pressing plate 16 pneumatically fixes the bumper on both sides to make the bumper stably fixed. When laser cutting round holes subsequently, the flatness is high. After the work is completed, the limit of the limiting bolt 21 can be released, and the entire base 2 can be moved or replaced through the handles 6 at the four corners of the base 2.
