[0002] Furniture welding refers to the process of connecting different parts together through welding technology during furniture manufacturing to achieve the stability and functionality of the furniture.

[0003] Existing furniture welding methods involve placing furniture parts on the welding machine's worktable, positioning them using a positioning mechanism, clamping them with a fixture, and then welding. However, this process is cumbersome because it requires positioning and clamping, and different models of positioning mechanisms and fixtures need to be used when processing furniture parts of different sizes, resulting in poor performance. Therefore, we propose a positioning fixture for furniture welding production. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned shortcomings in the existing technology by proposing a positioning fixture for furniture welding production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a positioning fixture for furniture welding production is designed, including a workbench, the bottom of which is fixed to the welding table by support legs;

[0006] The bottom of the workbench is rotatably connected to a mounting plate via a connecting shaft. The edges of the mounting plate are provided with two pairs of symmetrical guide grooves. One pair of guide grooves is provided with a first strip connecting plate inside, and the other pair of guide grooves is provided with a second strip connecting plate inside. One end of each first strip connecting plate and each second strip connecting plate extends out of the corresponding guide groove.

[0007] The first strip connecting plate has a first connecting rod rotatably connected to the top end away from the mounting plate, and the second strip connecting plate has a second connecting rod rotatably connected to the bottom end away from the mounting plate.

[0008] A horizontal plate is installed between two opposing legs. Two fixed blocks are symmetrically installed on the top of the horizontal plate. A worm gear is rotatably connected between the two fixed blocks. One end of the worm gear is connected to a drive motor, which is fixed on the fixed block. A turbine is installed at the bottom of the mounting plate, and the turbine meshes with the worm gear.

[0009] A fixing plate is installed at the end of each guide groove near the opening. The sides of the first strip connecting plate and the second strip connecting plate are provided with opening slots, which fit onto the fixing plate.

[0010] Each fixing plate has a threaded groove at its bottom, and each threaded groove has a screw inside. Each first strip connecting plate and the second strip connecting plate have a strip groove at their bottom. One end of the screw extends to the bottom of the corresponding strip groove, and a limit ring is installed on the side of the screw. When the screw is tightened, the bottom of the limit ring abuts against the bottom of the corresponding first strip connecting plate and the second strip connecting plate.

[0011] Preferably, guide rails are installed on both sides of the interior of each guide groove, and the two sides of the first strip connecting plate and the second strip connecting plate are slidably connected to the corresponding guide rails by sliders.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figures 1-5 A positioning fixture used in furniture welding production includes a workbench 1, the bottom of which is fixed to the welding table by support legs 6.

[0028] like Figure 1 and Figure 2 As shown, the bottom of the workbench 1 is rotatably connected to the mounting plate 12 via the connecting shaft 14. The edges of the mounting plate 12 are provided with two pairs of symmetrical guide grooves 13. One pair of guide grooves 13 is provided with a first strip connecting plate 8 inside, and the other pair of guide grooves 13 is provided with a second strip connecting plate 11 inside. One end of each first strip connecting plate 8 and each second strip connecting plate 11 extends out of the corresponding guide groove 13. In actual use, the first strip connecting plate 8 and the second strip connecting plate 11 can be moved along the guide groove 13, so that the length of the first strip connecting plate 8 and the second strip connecting plate 11 extending out of the guide groove 13 can be adjusted according to the size of the furniture parts to be clamped.

[0029] It should be noted that guide rails 15 are installed on both sides of the interior of each guide groove 13. The first strip connecting plate 8 and the second strip connecting plate 11 are slidably connected to the corresponding guide rails 15 through sliders. Under the action of the guide rails 15, the first strip connecting plate 8 and the second strip connecting plate 11 can be limited and guided, so that the first strip connecting plate 8 and the second strip connecting plate 11 remain stable.

[0030] like Figure 2 and Figure 3 As shown, the top end of the first strip connecting plate 8, away from the mounting plate 12, is rotatably connected to a first connecting rod 7. The bottom end of the second strip connecting plate 11, away from the mounting plate 12, is rotatably connected to a second connecting rod 10. The top ends of the first connecting rod 7 and the second connecting rod 10, away from the mounting plate 12, are rotatably connected to connecting blocks 3. The top of the workbench 1 has four through slots 4, and the top of each connecting block 3 extends to the top of the through slot 4. Each connecting block 3 has a clamping plate 2 installed on its top. In actual use, by rotating the mounting plate 12, the first strip connecting plate 8 and the second strip connecting plate 11 can rotate with the mounting plate 12. Figure 4 As shown, the first strip connecting plate 8 drives the first connecting rod 7 to move, and the second strip connecting plate 11 drives the second connecting rod 10 to move, so that the four clamping plates 2 can move synchronously along the through groove 4 to clamp and position the furniture parts.

[0031] It should be noted that each through groove 4 has a limiting rail on both sides inside. Each connecting block 3 is slidably connected to the corresponding limiting rail on both sides by a slider. In this way, the connecting block 3 will be limited by the limiting rail as it moves along the through groove 4, so that the connecting block 3 remains stable.

[0032] like Figure 1 and Figure 2 As shown, a horizontal plate 5 is installed between two opposing legs 6. Two fixing blocks 18 are symmetrically installed on the top of the horizontal plate 5. A worm gear 17 is rotatably connected between the two fixing blocks 18, and one end of the worm gear 17 is connected to a drive motor 9. The drive motor 9 is fixed on the fixing blocks 18. A turbine 16 is installed at the bottom of the mounting plate 12. The turbine 16 meshes with the worm gear 17. The drive motor 9 can drive the mounting plate 12 to rotate under the action of the turbine 16 and the worm gear 17, thereby controlling the movement of the clamping plate 2 to complete the clamping and positioning of furniture parts. Furthermore, there is a self-locking phenomenon between the turbine 16 and the worm gear 17. When the turbine 16 is under force, it will not drive the worm gear 17 to rotate, so that the clamping plate 2 is firmly clamped.

[0033] like Figure 5 As shown, a fixing plate 21 is installed at the end of each guide groove 13 near the opening. The sides of the first strip connecting plate 8 and the second strip connecting plate 11 are provided with opening grooves 25. The opening grooves 25 are fitted onto the fixing plate 21. The fixing plate 21 can perform secondary positioning of the first strip connecting plate 8 and the second strip connecting plate 11 to prevent the first strip connecting plate 8 and the second strip connecting plate 11 from falling out of the guide groove 13.

[0034] It should be noted that both the upper and lower ends of the fixing plate 21 are fitted with the inner wall of the opening groove 25 with a clearance, so that the first strip connecting plate 8 and the second strip connecting plate 11 can remain stable during use and will not shake.

[0035] like Figure 5 As shown, each fixing plate 21 has a threaded groove 20 at its bottom, and each threaded groove 20 has a screw 23 inside. Each first strip connecting plate 8 and second strip connecting plate 11 has a strip groove 22 at its bottom. One end of the screw 23 extends below the corresponding strip groove 22, and a limit ring 24 is installed on the side of the screw 23. When the screw 23 is tightened, the bottom of the limit ring 24 abuts against the bottom of the corresponding first strip connecting plate 8 and second strip connecting plate 11. In actual use, after adjusting the position of the first strip connecting plate 8 and second strip connecting plate 11 in the guide groove 13 according to the size of the furniture parts, the operator can tighten the screw 23. The limit ring 24 on the screw 23 can tightly abut against the bottom of the corresponding first strip connecting plate 8 and second strip connecting plate 11, fixing the first strip connecting plate 8 and second strip connecting plate 11 in place, which is convenient.

[0036] Specifically, in use, the worker places the furniture parts to be welded on the workbench 1, positioning them between the clamping plates 2. Then, the worker loosens the screw 23 and synchronously moves the clamping plates 2, the corresponding first strip connecting plate 8, and the second strip connecting plate 11 according to the dimensions of the furniture parts. After the clamping plates 2 are properly positioned, the worker tightens the screw 23 to fix the first strip connecting plate 8 and the second strip connecting plate 11. Then, the drive motor 9 is activated. Driven by the worm gear 16 and the worm 17, the drive motor 9 rotates the mounting plate 12. Figure 4 As shown, the first strip connecting plate 8 and the second strip connecting plate 11 rotate with the mounting plate 12, so that the first connecting rod 7 and the second connecting rod 10 rotate with the corresponding first strip connecting plate 8 and the second strip connecting plate 11. In this way, the connecting block 3 can move horizontally along the through groove 4, so that the clamping plate 2 moves synchronously to clamp and position the furniture parts placed on the workbench 1.

[0037] Furthermore, the top of each limiting ring 24 is provided with anti-slip teeth, which can increase the friction between the limiting ring 24 and the first strip connecting plate 8 and the second strip connecting plate 11, thereby improving the locking effect of the screw 23.

[0038] Furthermore, such as Figure 1 As shown, the top of the workbench 1 is equipped with scale lines, and the operator can adjust the distance between the clamping plates 2 according to the scale lines so that the distance between the clamping plates 2 matches the size of the furniture parts to be welded.

[0039] Furthermore, such as Figure 5 As shown, each screw 23 is equipped with a knob 19 at its bottom end. The knob 19 reduces the difficulty for workers to turn the screw 23 and makes it easier to fix the first strip connecting plate 8 and the second strip connecting plate 11 together using the screw 23.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
