[0003] In the existing technology, the traditional chassis welding usually prepares multiple parts to be welded, and uses welding equipment, such as a welding machine, a welding gun, and a welding wire, to weld. After each part is welded, the next part to be welded is precisely spliced ​​to the corresponding position of the welded part. Figure 7 and Figure 8 , including several support rods 100, some of which have through holes 200, and several support rods 100 are spliced ​​to form a whole, wherein a part of the support rod 100 is provided with two side rods 300, and the two side rods 300 are symmetrically arranged on the support rods 100 on both sides, each side rod 300 is provided with a vertical rod 400, the vertical rod 400 is against the upper end surface of the side rod 300, the vertical rod 400 is provided with a top plate 500, and the top plate 500 is fixed to the end surface of the vertical rod 400 away from the side rod 300. The support rod 100 is also provided with a bent rod 600 and a connecting plate 700, the bent rod 600 is erected above the support rod 100, and the top plate 500, the bent rod 600, the side rod 300 and the connecting plate 700 all have through holes 200. According to the design requirements, each component is welded to the specified position in sequence to combine into a bottom frame as a whole.

[0004] The above-mentioned chassis welding method requires each component to be welded one by one during operation. After the welding of the current component is completed, other components are moved to the corresponding positions and then welded. The operation is cumbersome and needs to be improved. Summary of the invention

[0005] In order to improve the problem of cumbersome welding operations of each part one by one, the present technical solution provides a chassis welding tool.

[0006] The purpose of this technical solution is achieved in this way:

[0007] A chassis welding tool comprises a workbench, wherein the workbench is provided with a support assembly, wherein the support assembly is used for a corresponding bracket rod to abut against, and the workbench is also provided with a clamping device, wherein the clamping device is used for clamping the bracket rod onto the corresponding support assembly to position it.

[0008] Through the above technical solution, when the chassis welding tooling is used normally, the workbench serves as an operating platform for welding work, the support assembly is preset in a fixed position corresponding to the required chassis structure, and a number of bracket rods are against the support assembly one by one. The bracket rods are accurately positioned by the support assembly and can be spliced ​​to form a chassis, thereby improving the rapid positioning and positioning accuracy of the bracket rods, and welding seams are left between the bracket rods by welding, making the welding operation easier.

[0009] The clamping device is used in conjunction with the support assembly. The clamping device is operated to clamp the bracket rod onto the support assembly for welding operations, thereby reducing the swing and deviation of the bracket rod caused by external forces during welding, improving the positioning stability of the bracket rod, and thereby improving the welding accuracy and the stability of the welding process.

[0010] Preferably, the workbench is provided with a first positioning assembly, which includes a positioning seat 1, a positioning column 1 slidably connected to the positioning seat 1, and a positioning drive component driving the positioning column 1 to slide. The positioning seat 1 is fixed on the workbench, and the positioning seat 1 is used for the corresponding support rod to abut against. The positioning drive component drives the positioning column 1 to pass through the positioning seat 1 so that the positioning column 1 is embedded in the through hole of the support rod.

[0011] Through the above technical scheme, the position of the first positioning component corresponds to the position setting of the through hole on the bracket rod, and the positioning driving member drives the positioning column to slide until it protrudes from the upper end surface of the positioning seat. After the through hole of the bracket rod is aligned with the positioning column, the bracket rod is now against the positioning seat and the supporting component at the same time, further improving the accuracy of the placement and positioning of each bracket rod, thereby making the bracket rod more stable during welding. When the welding is completed, the positioning driving member drives the positioning column to retract into the positioning seat, so that the positioning column is disengaged from the bracket rod and no longer has a fixing effect on the bracket rod, which makes it easy to remove the welded chassis from the workbench, thereby improving the convenience of operation.

[0012] Preferably, the support assembly includes a plurality of support seats, and the upper end surface of each support seat is provided with a limiting groove, and the limiting groove is adapted to the support rod for embedding and positioning the support rod.

[0013] Through the above technical scheme, the shape and size of the limit groove are adapted to the bracket rod, and the bracket rod is positioned by embedding in the limit groove, so that the bracket rod is firmly and stably in the limit groove, further limiting the shaking or displacement of the bracket rod due to external force during welding, reducing the error of the welding position, and helping to improve the welding accuracy and efficiency.

[0014] Preferably, the workbench is provided with a second positioning assembly, which includes a second positioning seat and a second positioning column, wherein the second positioning column protrudes from the upper end surface of the second positioning seat and is used to be embedded in the through hole of the side rod.

[0015] Through the above technical solution, the through hole of the side rod is aligned with the positioning column 2 in the second positioning assembly so that the through hole is completely embedded with the positioning column 2. One end of the side rod can rest on the positioning seat 2. Based on the upper end surface of the positioning seat 2 being flush with the bottom of the limiting groove, the other end of the side rod is embedded in the limiting groove and rests on the bottom of the limiting groove for positioning, thereby improving the positioning stability. At this time, the side surface of the other end of the side rod is close to the positioned bracket rod and a welding seam is left, thereby facilitating the welding and fixation of the side rod and the bracket rod.

[0016] Preferably, the workbench is also provided with a third positioning assembly, which includes a positioning seat three, a positioning block hinged to the positioning seat three, and a positioning member rotatably connected to the positioning block, the positioning block is flipped along the hinge axis to rest against the top plate, the positioning member has a positioning column three, and the positioning member drives the positioning column three to be embedded in the through hole of the top plate.

[0017] Through the above technical solution, the vertical rod is placed on the side rod, and the top plate of the vertical rod is located at the end of the vertical rod away from the side rod. By turning the positioning block along the hinge axis to be close to the top plate, the positioning column three of the positioning member is correspondingly embedded in the through hole of the top plate to realize the positioning of the top plate. The positioning block presses the vertical rod downward to rest against the side rod, thereby facilitating the welding operation between the vertical rod and the side rod. The positioning member drives the positioning column three to disengage from the through hole, thereby avoiding the collision between the positioning column three and the inner wall of the through hole after welding is completed, affecting the smooth removal, thereby improving operability.

[0018] Preferably, the workbench is provided with a fourth positioning component, and the fourth positioning component includes a positioning seat four and a positioning column four, the positioning seat four extends below the bending rod, and the positioning column four protrudes from the upper end surface of the positioning seat four and is used to be embedded in the through hole of the bending rod.

[0019] Through the above technical solution, the through hole of the bent rod is aligned with the positioning column four in the fourth positioning assembly to achieve complete fit, and the bent rod is positioned against the upper end surface of the positioning seat four to improve the positioning accuracy. At this time, welding seams are left between both ends of the bent rod and the bracket rod, and the position of the bent rod is stably fixed, thereby facilitating the welding and fixation of the bent rod and the bracket rod.

[0020] Preferably, the workbench is provided with a fifth positioning assembly, and the fifth positioning assembly includes a positioning seat five and a positioning column five, and the positioning column five protrudes from the upper end surface of the positioning seat five and is used to be embedded in the through hole of the connecting plate.

[0021] Through the above technical solution, the through hole at one end of the connecting plate is aligned with the positioning column five in the fifth positioning assembly for insertion, and the connecting plate is positioned against the upper end surface of the positioning seat five to improve the positioning accuracy. At this time, a welding seam is left between the other end of the connecting plate and the bracket rod, and the position of the connecting plate is stably fixed, thereby facilitating the welding and fixation of the connecting plate and the bracket rod.

[0022] Compared with the prior art, the technical solution has the following outstanding and beneficial technical effects:

[0023] 1. This technical solution provides a support assembly on the workbench, and a plurality of bracket rods are against the support assembly one by one, so that the bracket rods are accurately positioned and can be spliced ​​to form a base frame, thereby improving the positioning accuracy of the bracket rods.

[0024] 2. This technical solution provides a clamping device on the workbench, operates the clamping device to clamp the bracket rod on the support assembly, and then performs the welding operation, thereby reducing the swing deviation of the bracket rod affected by external forces during welding, improving the welding accuracy and the stability of the welding process;

[0025] 3. The technical solution is to provide a first positioning component on the workbench, the first positioning component includes a positioning seat, a positioning column and a positioning drive. The positioning drive drives the positioning column to protrude, and the through hole of the bracket rod is aligned with the positioning column to be embedded and positioned, thereby improving the positioning accuracy. The positioning drive drives the positioning column to retract, which is convenient for taking out the bracket rod after welding. BRIEF DESCRIPTION OF THE DRAWINGS
