[0037] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0038] Please refer to Figure 1-Figure 6 The utility model discloses a welding positioning tool for a fork, wherein the fork 400 includes a horizontal section 420 and a vertical section 410, wherein the horizontal section 420 includes two fork plates 421, and the vertical section 410 includes a bottom plate 413, a top seat 411 and two side plates 412, wherein the two side plates 412 gradually tilt outward from the top seat 411 toward the bottom plate 413, and the welding positioning tool includes:

[0039] A fixed frame 300, on which the fork 400 is arranged;

[0040] A first positioning assembly 100 is disposed on the fixing frame 300, and the first positioning assembly 100 includes: a first abutting column 110 and a second abutting column 120 that are movably disposed, the first abutting column 110 can abut against the upper surface of the top seat 411, and the second abutting column 120 can abut against the lower surface of the top seat 411; a movably disposed positioning seat, the positioning seat includes two positioning plates 130, and each positioning plate 130 can abut against one of the side plates 412;

[0041] The second positioning assembly 200 is arranged on the fixing frame 300, and the second positioning assembly 200 includes: an abutment plate 270, which is arranged above the horizontal section 420 and can abut against the upper surface of the fork plate 421; two locking blocks 210, each of which can slide along the width direction of the fork 400 to abut against or separate from the side wall of the fork plate 421.

[0042] Specifically, the present application places multiple plates of the fork 400 on the fixing frame 300, and arranges the first positioning assembly 100 on the fixing frame 300. The top seat 411 is positioned by the first abutting column 110 and the second abutting column 120 on the first positioning assembly 100, and the two side plates 412 are positioned by the positioning seat, so that the entire vertical section 410 can be accurately positioned, which is convenient for welding; at the same time, the second positioning assembly 200 is arranged on the fixing frame 300, and the abutting plate 270 and the locking block 210 in the second positioning assembly 200 are used to accurately position the fork plate 421, which is convenient for welding with the vertical section 410. That is, by arranging the first positioning assembly 100 and the second positioning assembly 200 on the fixing frame 300, the vertical section 410 and the horizontal section 420 are positioned and clamped respectively, so as to accurately position and clamp each plate, so as to make the welds between each plate more uniform and more reliable during welding.

[0043] Furthermore, the first positioning assembly 100 also includes: a support seat 183, which is arranged on the fixing frame 300, and the support seat 183 can abut against the lower surface of the base plate 413; and a movably arranged clamping block 180, and the clamping block 180 can abut against the upper surface of the base plate 413.

[0044] Specifically, the support seat 183 is provided to support the lower surface of the bottom plate 413, and then the upper surface of the bottom plate 413 is pressed by the pressing block 180 to achieve positioning and clamping of the bottom plate 413. In this way, the top seat 411, the two side plates 412 and the bottom plate 413 in the entire vertical section 410 are precisely positioned and clamped.

[0045] Furthermore, a shaft sleeve hole 414 is respectively provided on the two side plates 412;

[0046] The first positioning assembly 100 also includes two positioning units respectively located on both sides of the vertical section 410, and the positioning units include: a sliding seat 191 slidably connected to the fixing frame 300, and a positioning rod 190 is arranged on the sliding seat 191. The positioning rod 190 can slide relative to the fixing frame 300 to extend into or exit the sleeve hole 414.

[0047] Specifically, if the positions of all the plates of the vertical section 410 are correct, the positioning rod 190 can slide along the width direction to extend into the shaft sleeve hole 414. If not, the positioning rod 190 cannot extend into the shaft sleeve hole 414. In this way, the positioning rod 190 can be used to detect whether the positions of the plates of the vertical section 410 are correct.

[0048] Furthermore, the first positioning assembly 100 also includes: a first rotating cylinder 160 for driving the first abutment column 110 to rotate, rotating the first abutment column 110 so that it abuts against or separates from the upper surface of the top seat 411; and a second rotating cylinder 170 for driving the positioning seat to rotate, rotating the positioning seat so that it abuts against or separates from the two side plates 412.

[0049] Further, the positioning seat includes a fixing block 150, the fixing block 150 is connected to the second rotating cylinder 170; two connecting blocks 140, the two connecting blocks 140 are connected to the fixing block 150 at the same time, and one end of the connecting block 140 away from the fixing block 150 is connected to the positioning plate 130;

[0050] The connecting block 140 is gradually inclined outward along the fixing block 150 toward the top seat 411 .

[0051] During the downward rotation of the positioning seat, the two outwardly inclined connecting blocks 140 drive the two positioning plates 130 to rotate downward until they abut against the two side plates 412. If the positions of the two side plates 412 are offset, the two side plates 412 can be moved a certain distance during the downward rotation of the positioning seat until the two positioning plates 130 abut against the two side plates 412 respectively, so as to correct the positions of the side plates 412.

[0052] Furthermore, the first positioning assembly 100 also includes: a rotating rod 181, one end of which is rotatably connected to the fixed frame 300, and the other end is connected to the clamping block 180; a telescopic cylinder 182, one end of which is hinged to the fixed frame 300, and the other end is hinged to the middle part of the rotating rod 181.

[0053] The telescopic cylinder 182 drives the rotating rod 181 to rotate relative to the fixing frame 300 , and at the same time drives the pressing block 180 on the rotating rod 181 to move toward or away from the bottom plate 413 , so that the pressing block 180 abuts against or separates from the bottom plate 413 .

[0054] Furthermore, the locking block 210 includes a main body 211, and the main body 211 can be in contact with or separated from the outer wall of the fork plate 421; the lower end of the main body 211 is bent outward to form a hook portion 212, and the hook portion 212 can be in contact with or separated from the lower surface of the fork plate 421;

[0055] The second positioning assembly 200 further includes two limit blocks 220 . The two limit blocks 220 are located at the inner side of the two fork plates 421 . The limit blocks 220 can abut against the inner side walls of the fork plates 421 .

[0056] Specifically, the lower end of the main body 211 is bent inward to form a hook portion 212, the hook portion 212 abuts against the lower surface of the fork plate 421, and the main body 211 abuts against the side wall of the fork plate 421. With the aid of the limit block 220 abutting against the other side of the fork plate 421, precise positioning and clamping of the fork plate 421 can be achieved.

[0057] Furthermore, the fork plate 421 has a top surface and two side surfaces, and each of the side surfaces is provided with a support plate hole 422;

[0058] The second positioning assembly 200 also includes:

[0059] The positioning cylinder 250 has a telescopic rod that can be telescoped along the width direction of the fork plate 421 to extend into the support plate hole 422 .

[0060] Specifically, by checking whether the telescopic rod in the positioning cylinder 250 can smoothly extend into the support plate hole 422, it can be detected whether the position of the fork plate 421 is correct.

[0061] Furthermore, one positioning cylinder 250 is disposed on both sides of each fork plate 421;

[0062] A sensing seat 260 is arranged between the two positioning cylinders 250, and a sensing hole 261 is provided on both sides of the sensing seat 260 to allow the telescopic rod of the positioning cylinder 250 to extend into. The telescopic rod of the positioning cylinder 250 can pass through the support plate hole 422 and extend into the sensing hole 261 to trigger the sensing signal of the sensing seat 260.

[0063] A sensing seat 260 is provided. When the telescopic rod passes through the support plate hole 422 and extends into the sensing hole 261, the sensing seat 260 sends a signal indicating that the fork plate 421 is in the correct position or sends no signal. When the telescopic rod cannot pass through the support plate hole 422, it cannot extend into the sensing hole 261. At this time, the sensing seat 260 sends a signal indicating that the fork plate 421 is in an incorrect position, so as to remind the staff to correct the position of the fork plate 421 before welding.

[0064] Furthermore, a first slider 230 is provided on the fixing frame 300, and the first slider 230 can slide relative to the fixing frame 300 along the length direction of the fork plate 421; two second sliders 240 are provided on the first slider 230, and the second sliders 240 can slide relative to the first slider 230 along the width direction of the fork plate 421, and each of the second sliders 240 is provided with two positioning cylinders 250 and one sensing seat 260.

[0065] Specifically, a first slide block 230 and a second slide block 240 are provided to drive the plurality of telescopic cylinders 182 and the sensing seat 260 to slide along the length direction and the width direction of the fork plate 421 to adapt to forks 400 of different sizes.
