DETAILED DESCRIPTION

[0018] The following is combined with Figure 1-3This application is described in further detail.

[0019] The present application embodiment discloses a handheld welding positioning tool. Figure 1-3 A handheld welding positioning tool comprises a workbench 1, the top outer wall of the workbench 1 is fixedly connected to two slide rails 2, the outer walls of the two slide rails 2 are slidably connected to a plurality of sliders 3, the top outer walls of every two sliders 3 along the width direction of the workbench 1 are fixedly connected to a moving plate 4, the top outer wall of the moving plate 4 is fixedly connected to two fixed plates 5, the outer wall of the moving plate 4 located between the two fixed plates 5 is installed with two moving blocks 7, the top outer walls of the plurality of moving blocks 7 are fixedly connected to a positioning fixture 8, the outer wall of the moving plate 4 is installed with a positioning mechanism for driving every two positioning fixtures 8 to move relative to each other, the positioning mechanism comprises a mounting frame 9 fixedly connected to the outer walls of the middle sections of the two moving plates 4, the bottom inner wall of the mounting frame 9 is rotatably connected to a gear 11 through a rotating shaft 10, the outer walls opposite to each other of the two moving blocks 7 are fixedly connected to a rack 12, the rack 12 passes through the mounting frame 9 and meshes with the gear 11.

[0020] The positioning mechanism further includes a cylinder 13 fixedly mounted on the outer walls of the two mounting frames 9 , and an output end of the cylinder 13 penetrates the mounting frames 9 and is fixedly connected to a moving block 7 through a connecting block 14 .

[0021] The opposite outer walls of every two fixed plates 5 are fixedly connected to two limiting rods 6 , and the moving block 7 is slidably connected to the outer walls of the limiting rods 6 .

[0022] Mounting plates 15 are welded at both ends of the two slide rails 2, and the middle outer walls of the two mounting plates 15 are rotatably connected to a bidirectional screw rod 16. The middle bottom outer walls of the two movable plates 4 are fixedly connected to a threaded block 17, and the two threaded blocks 17 are symmetrically threadedly connected to the outer walls of the bidirectional screw rod 16.

[0023] A servo motor 18 is fixedly mounted on the outer wall of one of the mounting plates 15 . The end of the output shaft of the servo motor 18 passes through the mounting plate 15 and is fixedly connected to one end of the bidirectional lead screw 16 .

[0024] The implementation principle of a handheld welding positioning tool in the embodiment of the present application is as follows: when in use, two workpieces to be welded are placed between every two positioning fixtures 8, and then the cylinder 13 is started through the positioning mechanism, and the output shaft of the cylinder 13 is extended and retracted to push or pull a moving block 7 to move through the connecting block 14, and when a moving block 7 moves toward the middle section of the moving plate 4 on the outer wall of the two limit rods 6, a rack 12 will drive the gear 11 meshed with it to rotate, and when the gear 11 rotates, it drives another rack 12 meshed with it to move, so that the two racks 12 located on a moving plate 4 move relatively synchronously, and the two racks 12 drive the two moving blocks 7 to move relatively synchronously, and every two moving blocks 7 drive every two positioning fixtures 8 to center, position, clamp and fix the two workpieces to be welded;

[0025] Then, the servo motor 18 is started, and the output shaft of the servo motor 18 drives the bidirectional screw 16 to rotate. The bidirectional screw 16 rotates on the inner surface threads of the two threaded blocks 17, so that the two threaded blocks 17 move relatively along the outer wall of the bidirectional screw 16, and the two moving plates 4 are driven to move relatively close to each other through the two threaded blocks 17, so that the workpieces clamped on the two moving plates 4 are quickly aligned and abutted against each other, and hand-held welding can be performed at this time. Compared with the prior art, the relative movement of the two positioning fixtures 8 can center the workpiece, and the relative movement of the two moving plates 4 can quickly abut the two centered workpieces to ensure the accuracy of hand-held welding;

[0026] It is worth noting that when the two moving blocks 7 drive the positioning fixture 8 to move, they will slide on the outer walls of the multiple limit rods 6. The multiple limit rods 6 play a limiting and guiding role in the movement of the moving blocks 7, so that the two moving blocks 7 can move stably linearly. At the same time, when the two moving plates 4 move relative to each other, they will drive the multiple sliders 3 to slide on the outer walls of the two slide rails 2. The coordinated sliding of the two slide rails 2 and the sliders 3 plays a limiting and guiding role in the movement of the moving plates 4, so that the two moving plates 4 can move stably linearly, further improving the stability of positioning.
