[0032] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0033] like Figure 1-3 As shown, an electric pallet truck leg welding fixture includes a support mechanism 100, a positioning mechanism 200, and a control mechanism 300. The support mechanism 100 provides support for the legs, the positioning mechanism 200, and the control mechanism 300. The positioning mechanism 200 fixes the various components of the legs in their corresponding positions to ensure the accuracy of subsequent welding. The control mechanism 300 is used for the operator to operate the positioning mechanism 200.

[0034] In this embodiment, the foot includes a foot body 410, a bending plate 420, and a stiffening plate 430. The welding fixture is used to weld the bending plate 420 and the stiffening plate 430 to the corresponding positions of the foot body 410.

[0035] Specifically, the support mechanism 100 includes a welding platform 110, on which the positioning and welding of the vehicle leg are completed. The positioning mechanism 200 includes a first positioning component 210, a second positioning component 220, and a third positioning component 230. The first positioning component 210 is disposed on the welding platform 110 and is at least partially movably disposed to position the vehicle leg body 410 on the welding platform 110. The second positioning component 220 is disposed on the welding platform 110 and is at least partially movably disposed to position the folding... The bending plate 420 is positioned on the inner side of the front end of the main body 410 of the car foot. The third positioning component 230 is set on the welding platform 110. At least part of the third positioning component 230 is movably set to position the stiffening plate 430 on the inner side of the rear end of the main body 410 of the car foot. The positioning mechanism 200 can realize the positioning of the main body 410 of the car foot, the bending plate 420 and the stiffening plate 430. After positioning, they can be welded to the main body 410 of the car foot, thereby completing the automatic welding of the car foot and improving its welding accuracy and welding efficiency.

[0036] Furthermore, there are two first positioning components 210. The two first positioning components 210 are arranged on the welding platform 110 along the length direction of the welding platform 110 and can simultaneously clamp the foot body 410. The foot body 410 is arranged on the welding platform 110 along the length direction of the welding platform 110. Using two first positioning components 210 can improve the clamping stability of the foot body 410.

[0037] Furthermore, each first positioning component 210 includes a limiting block 211 and a pre-tightening cylinder 212 arranged on opposite sides of the welding platform 110 along the width direction of the welding platform 110. The piston rods of the limiting block 211 and the pre-tightening cylinder 212 can simultaneously abut against the two opposite outer sides of the foot body 410. That is, the foot body 410 can be placed between the limiting block 211 and the pre-tightening cylinder 212. Then, by extending the piston rod of the pre-tightening cylinder 212, the foot body 410 is driven to move to the two outer sides to abut against the piston rods of the limiting block 211 and the pre-tightening cylinder 212 respectively. Thus, the limiting block 211 and the piston rod of the pre-tightening cylinder 212 are used to clamp and position the foot body 410.

[0038] Furthermore, the second positioning component 220 includes two first positioning cylinders 221. The two outer walls at the front end of the foot body 410 are provided with front end holes 411. The bending plate 420 is provided with mounting holes 421 corresponding to the front end holes 411. The piston rod of the first positioning cylinder 221 is provided with a positioning shaft 221a. The positioning shaft 221a can pass through the front end hole 411 and the mounting hole 421 in sequence. The two first positioning cylinders 221 are located on both sides of the foot body 410 and are used for the initial positioning of the two bending plates 420. That is, after the positioning shaft 221a passes through the front end hole 411 and the mounting hole 421, the positioning shaft 221a can be used to provide initial positioning, ensuring the relative position of the bending plate 420 and the foot body 410, and preventing the bending plate 420 from shifting laterally.

[0039] Furthermore, the second positioning component 220 also includes a second positioning cylinder 222. The second positioning cylinder 222 is arranged vertically between the two inner walls at the front end of the foot body 410. The piston rod of the second positioning cylinder 222 is provided with a pressing column 222a. The two ends of the pressing column 222a can respectively fit against the inner side of the two bending plates 420 so that the bending plates 420 are kept in contact with the foot body 410. That is, the pressing column 222a is driven to move up and down by the second positioning cylinder 222. When it moves between the two bending plates 420, the two ends of the pressing column 222a respectively press the two bending plates 420 to perform secondary positioning of the two bending plates 420.

[0040] Furthermore, the second positioning component 220 also includes a positioning frame 223, which provides support for the two first positioning cylinders 221 and the second positioning cylinder 222. In this embodiment, the positioning frame 223 is arch-shaped, with its two sides fixed to the welding platform 110 along its width. The two first positioning cylinders 221 are fixed to both sides of the positioning frame 223, and the second positioning cylinder 222 is fixed to the top of the positioning frame 223. The end of the extrusion column 222a is provided with a positioning hole, and one end of the positioning shaft 221a can extend into the positioning hole. The cooperation between the positioning shaft 221a and the positioning hole can achieve complete positioning and avoid interference between the positioning shaft 221a and the extrusion column 222a.

[0041] Furthermore, the third positioning component 230 includes a clamping cylinder 231, a connecting seat 232, and an inner support cylinder 233. The clamping cylinder 231 is fixed vertically to one side of the welding platform 110. The inner support cylinder 233 is connected to the piston rod of the clamping cylinder 231 via the connecting seat 232. A pressure plate 232a is provided on one side of the connecting seat 232. The pressure plate 232a can abut against the top of the rear end of the vehicle leg body 410. The inner support cylinder 233 can descend to the inner side of the rear end of the vehicle leg body 410 and can drive the stiffening plate 430 to... The inner side of the rear end of the main body 410 of the foot is fitted together. The pressing cylinder 231 can press the rear end of the main body 410 of the foot from above through the pressure plate 232a, and can also drive the inner support cylinder 233 to descend through the connecting seat 232, so that the inner support cylinder 233 can move to the space between the two sides of the main body 410 of the foot, that is, the inner side of the rear end of the main body 410 of the foot. When the inner support cylinder 233 moves into place, its piston rod can extend, thereby driving the rib plate 430 to keep it fitted with the inner side of the rear end of the main body 410 of the foot, which is convenient for subsequent welding.

[0042] Furthermore, in order to achieve the installation and positioning of the clamping cylinder 231, the third positioning component 230 also includes a connecting plate 234. One end of the connecting plate 234 is connected to the clamping cylinder 231, and the other end of the connecting plate 234 is connected to the welding platform 110. That is, the connecting plate 234 provides support for the clamping cylinder 231. In this embodiment, the connecting plate 234 and the welding platform 110 are detachably connected, and the clamping cylinder 231 and the connecting plate 234 are also detachably connected, which facilitates maintenance and replacement.

[0043] Furthermore, the support mechanism 100 also includes a front positioning bracket 120 and support blocks 130 for providing support for the main body 410 of the chassis frame. The front positioning bracket 120 is installed at the front of the welding platform 110, and multiple support blocks 130 are spaced apart at the middle and rear of the welding platform 110. The height of the multiple support blocks 130 is the same as the height of the front positioning bracket 120. The front positioning bracket 120 can provide support for the front end of the chassis frame 400, and the multiple support blocks 130 can provide support for the middle and rear ends of the main body 410 of the chassis frame, ensuring the support effect. Since the support blocks 130 are at the same height as the front positioning bracket 120, the levelness of the main body 410 of the chassis frame can be ensured, and the welding accuracy can be improved.

[0044] Specifically, the control mechanism 300 includes an electrical control panel 310, which is electrically connected to the first positioning component 210, the second positioning component 220, and the third positioning component 230. The electrical control panel 310 can independently control the first positioning component 210, the second positioning component 220, and the third positioning component 230 to perform corresponding actions, making operation convenient.

[0045] In this embodiment, the welding process is as follows:

[0046] 1. Place the main body 410 of the car foot on the welding platform 110 between the limiting block 211 and the pre-tightening cylinder 212, and bring it close to the limiting block 211;

[0047] 2. Place the bending plate 420 inside the front end of the foot body 410, and the positioning shaft 221a of the first positioning cylinder 221 extends into the connecting hole between the front end hole 411 and the mounting hole 421.

[0048] 3. The bending plate 420 is pressed against the inside of the foot body 410 by the second positioning cylinder 222;

[0049] 4. The main body 410 of the car foot is clamped by the pre-tightening cylinder 212;

[0050] 5. Place the stiffening plate 430 inside the rear end of the chassis body 410. First, open the clamping cylinder 231, which drives the pressure plate 232a to press down on the top of the chassis body 410. Then, open the inner support cylinder 233 to clamp the stiffening plate 430 and weld it in sequence.

[0051] 6. After welding is completed, release all cylinders at once to remove the material.
