Description

Technical Field

[0001] This utility model belongs to the field of hinge welding fixture technology, and particularly relates to a hinge welding fixture with adjustable gap. Background Technology

[0002] A hinge, also known as a latch, is a mechanical device used to connect two solid objects and allow relative rotation between them. Hinges can consist of movable components or be made of foldable materials. Hinges are mainly installed on doors and windows, while hinges are more commonly installed on cabinets. They are mainly classified by material into stainless steel hinges and iron hinges. To provide a better user experience, hydraulic hinges (also known as damping hinges) have emerged. In the process of using hinges, because the hinge width is relatively narrow, it cannot be used directly and requires the widening of the hinge blades by welding.

[0003] Patent No. CN216829289U discloses a hinge welding fixture with adjustable gap, aiming to provide a reasonably designed, cost-effective hinge welding fixture with adjustable hinge gap. This utility model includes a base plate and a hinge base disposed on the base plate. Hinge clamping mechanisms are provided on both sides of the hinge base, and a hinge axis positioning groove is provided in the middle of the hinge base. Hinge hinge positioning blocks are provided at both ends of the hinge axis positioning groove. Several bolt holes and bolts are provided on the hinge hinge positioning blocks. The welding gap between the hinge hinge and the hinge axis is adjusted by adjusting the height of the bolts after they are installed in the bolt holes above the horizontal plane of the hinge hinge positioning blocks.

[0004] In existing technologies, by setting a hinge axis positioning groove, the hinge position can be adjusted according to the bolts while the hinge is being positioned, thereby controlling the gap. However, the following problems still exist in overall use: First, in existing technologies, the diameter of the axis positioning groove is fixed and the depth of the axis positioning groove is not adjustable when positioning the hinge. This results in inconsistent hinge diameters and axis positioning groove diameters and heights. When welding hinges with larger diameters, the hinge cannot be welded to the hinge diameter, affecting the welding effect. Second, existing technologies use bolts to fix the hinge during positioning, which makes the operation complicated and affects work efficiency. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model provides a hinge welding fixture with adjustable gap. By setting an arc-shaped plate with an adjustable diameter, the groove formed by the arc-shaped plate can be adaptively adjusted according to the diameter of the hinge, ensuring that the diameter of the hinge is consistent with the horizontal level of the positioning table. This allows the hinge to be welded onto the diameter of the hinge, thereby effectively improving the hinge welding effect. By setting a pressing plate and a movable plate, the position of the positioned hinge can be adjusted, making the gap between the hinge and the hinge adjustable, thereby further improving the welding effect. Moreover, the operation is simple and convenient.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable hinge welding fixture, comprising a positioning table, with positioning blocks at both ends of the positioning table, and multiple adjustable arc-shaped plates between the two positioning blocks. A drive disk is rotatably mounted on one side of one of the positioning blocks, and multiple arc-shaped grooves are formed on the surface of the drive disk. A drive rod is slidably mounted inside each of the multiple arc-shaped grooves, and an adjustment block is slidably mounted at one end of each of the multiple drive rods inside the positioning block. The multiple adjustment blocks are respectively fixedly connected to the arc-shaped plates. Support plates are slidably mounted on both sides of the arc-shaped plates, and movable plates are slidably mounted on the end faces of the two support plates. A pressing plate is rotatably mounted above the two movable plates.

[0007] Preferably, the surfaces of both positioning blocks are provided with multiple sliding grooves, and the multiple sliding grooves are respectively slidably connected to multiple adjusting blocks.

[0008] Preferably, a clamping block is slidably provided on one side of the positioning block, and a first clamping roller is provided on both sides of the clamping block, the first clamping roller abutting against the end face of the movable plate.

[0009] Preferably, the inner wall of the positioning platform is provided with a plurality of limiting grooves, each of the plurality of limiting grooves is provided with a return spring, and the other end of each of the plurality of return springs is provided with a slider, and the plurality of sliders are respectively fixedly connected to both ends of the support plate.

[0010] Preferably, the support plate has multiple adjustment grooves on its end face, each adjustment groove has a sliding rod inside, and the sliding rods are fixedly connected to the bottom end face of the movable plate.

[0011] Preferably, each of the two movable plates is provided with a rotating connector on its end face, and each of the two rotating connectors is provided with a damping shaft inside, and the two damping shafts are respectively fixedly connected to the pressing plate.

[0012] Preferably, an elastic element is provided on the end face of the pressing plate.

[0013] Preferably, the inner wall of the positioning stage is provided with a plurality of second clamping rollers, and the second clamping rollers are arranged corresponding to the clamping rollers.

[0014] In summary, compared with existing technologies, the beneficial effects of this solution are as follows:

[0015] (1) This utility model sets up an arc plate with an adjustable diameter so that the groove formed by the arc plate can be adjusted according to the diameter of the hinge so that the diameter of the hinge is kept in line with the horizontal position of the positioning table, so that the hinge can be welded to the diameter of the hinge, thereby effectively improving the hinge welding effect.

[0016] (2) By setting up a pressing plate and a movable plate, the position of the positioned hinge can be adjusted, so that the gap between the hinge and the hinge can be adjusted, thereby further improving the welding effect, and the operation is simple and convenient.

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Example 1:

[0026] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4An adjustable hinge welding fixture includes a positioning table 1, with positioning blocks 2 at both ends of the positioning table 1. Multiple adjustable arc-shaped plates 3 are arranged between the two positioning blocks 2. A drive disk 4 is rotatably arranged on one side of one of the positioning blocks 2. Multiple arc-shaped grooves 5 are formed on the surface of the drive disk 4. Drive rods 6 are slidably arranged inside the multiple arc-shaped grooves 5. Adjusting blocks 7 are slidably arranged at one end of the multiple drive rods 6 inside the positioning block 2. The multiple adjusting blocks 7 are fixedly connected to the arc-shaped plates 3 respectively. Support plates 8 are slidably arranged on both sides of the arc-shaped plates 3. Movable plates 9 are slidably arranged on the end faces of the two support plates 8. A pressing plate 10 is rotatably arranged above the two movable plates 9.

[0027] In this design, the cross-section of the arc plate 3 is arc-shaped, and the upper arc surfaces of multiple arc plates 3 form an axial positioning groove. The hinge is placed inside the axial positioning groove for easy positioning. The adjusting block 7 is T-shaped overall, and the longer end of the adjusting block 7 is also arc-shaped, with the same curvature as the arc plate 3. When the adjusting block 7 moves, it will drive the arc plate 3 to move, causing multiple arc plates 3 to move along the slide groove 11 towards the bottom, thus increasing the diameter of the axial positioning groove formed by the arc plates 3 to accommodate hinges of various diameters. The pressing plate 10 can press and clamp the upper hinge on the end face of the movable plate 9, thereby positioning the hinge and preventing it from moving during welding, thus effectively improving the welding effect. Furthermore, by setting the pressing plate 10, the pressing plate 1... The hinge is clamped downwards, facilitating the movement of the movable plate 9 while allowing the hinge to be moved to adjust the gap between the hinge and the hinge. A servo motor 23 is installed at one end of the positioning table 1. The output end of the servo motor 23 is fixedly connected to the drive disk 4. The servo motor 23 is existing technology and will not be elaborated on in this article. Its main function is to drive the drive disk 4 to rotate. When the drive disk 4 rotates, the arc groove 5 on its surface will press the drive rod 6 according to the slope of the arc groove 5, causing the drive rod 6 to move. However, due to the restriction of the slide groove 11, the drive rod 6 can only move along the slide groove 11. This setting allows multiple drive rods 6 to move towards the center and move outwards in a distributed manner, thereby driving the arc plate 3 to move, so that the arc plate 3 can adapt to hinges of various sizes.

[0028] refer to Figure 4 The surfaces of the two positioning blocks 2 are provided with multiple sliding grooves 11, which are slidably connected to multiple adjusting blocks 7 respectively.

[0029] In this scheme, the tilting trend of multiple slide grooves 11 spreads outward from the center, which limits the adjustment block 7 in the slide groove 11, so that the adjustment block 7 can only move outward through the slide groove 11, thereby adjusting the arc plate 3.

[0030] refer to Figure 1 and Figure 2A clamping block 12 is slidably arranged on one side of the positioning block 2, and a first clamping roller 13 is arranged on both sides of the clamping block 12. The first clamping roller 13 abuts against the end face of the movable plate 9. A plurality of second clamping rollers 22 are arranged on the inner wall of the positioning table 1, and the second clamping rollers 22 are arranged corresponding to the clamping rollers.

[0031] In this scheme, a drive cylinder 24 is provided at one end of the positioning table 1. The output shaft of the drive cylinder 24 is fixedly connected to the clamping block 12. The clamping block 12 slides on the top end face of the arc plate 3. The drive cylinder 24 is existing technology and will not be elaborated on in this article. Its main function is to push the clamping block 12 to move, thereby abutting and fixing the hinge above the arc plate 3. The first clamping rollers 13 on both sides of the clamping block 12 will push the hinge to move and abut the hinge against the outer circular surface of the second clamping roller 22. This setting allows the position of the hinge to be adjusted by pressing the movable plate 9 after the hinge is fixed, thereby improving the flexibility of the device.

[0032] refer to Figure 3 and Figure 5 The inner wall of the positioning platform 1 is provided with multiple limiting grooves 14, and each limiting groove 14 is provided with a return spring 15. Each of the other ends of the multiple return springs 15 is provided with a slider 16, and the multiple sliders 16 are respectively fixedly connected to both ends of the support plate 8.

[0033] In this design, the support plate 8 is shaped like a "7". When the arc plate 3 moves in a distributed manner, it pushes against the support plates 8 on both sides. This arrangement allows the arc plate 3 to abut against one side of the support plate 8 and move, preventing the arc plate 3 from entering the bottom of the support plate 8 and getting stuck, thereby improving the stability of the device. When the support plate 8 moves along the slide groove 11, it will compress the internal return spring 15. Due to the elastic potential energy, the return spring 15 will stretch and push the support plate 8 towards the arc plate 3, so that the support plate 8 always abuts against the outer surface of the arc plate 3, thereby restoring the support plate 8 to its original position for easy use next time.

[0034] refer to Figure 5 and Figure 6 The support plate 8 has multiple adjustment grooves 17 on its end face. Each adjustment groove 17 has a slide rod 18 inside. The slide rod 18 is fixedly connected to the bottom end face of the movable plate 9. Each movable plate 9 has a rotating connector 19 on its end face. Each rotating connector 19 has a damping shaft 20 inside. The two damping shafts 20 are fixedly connected to the pressing plate 10. The pressing plate 10 has an elastic element 21 on its end face.

[0035] In this design, the movable plate 9 can slide on the surface of the support plate 8 via the slide bar 18, and the hinge can be clamped by the top pressing plate 10, allowing the hinge to move laterally with the movable plate 9, thereby adjusting the gap between the hinge and the hinge. The operation is simple and convenient. The elastic element 21 can adapt to hinges of various thicknesses, thereby improving the clamping effect. The damping pivot 20 is existing technology and will not be discussed in detail in this paper. Its main function is to fix the angle of the pressing plate 10.

[0036] In use, the hinge is placed on the end face of the arc plate 3, and the hinge is placed on the end face of the movable plate 9. Then, the drive cylinder 24 is activated, causing the output shaft of the drive cylinder 24 to push the clamping block 12 to move along the arc plate 3. The clamping block 12 drives the first clamping rollers 13 on both sides to move. The clamping block 12 and the first clamping rollers 13 respectively push the hinge and the hinge to move, and the other end of the hinge abuts against the outer circular surface of the second clamping roller 22. After positioning, the pressing plate 10 is rotated, so that the elastic element 21 at the upper end of the pressing plate 10 flips down and abuts against the end face of the hinge. Then, the movable plate 9 is pulled. Since the hinge is abutted and clamped by the first clamping roller 13 and the second clamping roller 22, the first clamping roller 13 and the second clamping roller 22 will rotate when the hinge moves, so the hinge can move between the first clamping roller 13 and the second clamping roller 22, thereby adjusting the gap between the hinge and the hinge. The operation is simple and convenient, and effectively improves the welding efficiency.

[0037] When welding hinges of different diameters is required, the servo motor 23 is started. The output shaft of the servo motor 23 drives the drive disk 4 to rotate. The drive disk 4 drives the arc groove 5 on its surface to rotate. When the arc groove 5 rotates, it will press the drive rod 6 according to the inclined surface of the arc groove 5, causing the drive rod 6 to move. The drive rod 6 drives the adjustment block 7 at one end to move. However, due to the limitation of the slide groove 11, the adjustment block 7 can only move along the slide groove 11. The adjustment block 7 moves outward in a dispersed manner. When the adjustment block 7 moves, it will drive the arc plate 3 on one side to move, so that the arc plate 3 also moves in a dispersed manner, causing the arc surface of the arc plate 3 to expand to the bottom, thereby adjusting the diameter of the axial positioning groove formed by the arc plate 3, so that the arc plate 3 can adapt to hinges of various sizes.
