Description

Technical Field

[0001] This utility model relates to the field of metal crafts processing, specifically to a large-scale metal crafts welding auxiliary mechanism. Background Technology

[0002] Large metal crafts refer to crafts made using metal materials such as gold, silver, copper, iron, and tin, or mainly metal materials supplemented by other materials. These crafts have a heavy, majestic, luxurious, elegant, and exquisite style. Auxiliary mechanisms refer to the auxiliary tools or equipment used in the welding process of large metal crafts. These tools or equipment help to complete the welding work and improve welding efficiency and quality. Fixing mechanisms are a type of auxiliary mechanism used to fix the crafts.

[0003] According to Chinese Patent No. CN217493231U, a copper craft processing welding positioning and fixing device is disclosed. This utility model uses a rotating block to drive the second clamping plate to move, so that the second clamping plate clamps the copper craft for a second time. At the same time, the length of the second clamping plate can be changed by a round rod to improve its adjustability. Thus, by fixing the copper craft with the first clamping plate and the second clamping plate at the same time, the original two force points are changed to four force points, making it more stable when clamping irregularly shaped copper crafts.

[0004] Regarding the aforementioned patent content, a first clamping plate and a second clamping plate are provided to clamp and limit the crafts. However, since the shapes of the crafts vary, different clamps are required to clamp and limit them. Furthermore, since both the first clamping plate and the second clamping plate are fixedly installed on the mechanism, it is inconvenient to disassemble and replace them to adapt to crafts of different shapes, thereby reducing the applicability of the clamping structure. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a welding auxiliary mechanism for large metal crafts to solve the technical problem of poor applicability of clamping structures.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a welding auxiliary mechanism for large metal crafts, comprising a base plate and two movable plates. One side of each movable plate is provided with a disassembly and assembly assembly, which includes slots opened on one side of the two movable plates and two threaded posts installed on the top of the two movable plates. The outer walls of the threaded posts are respectively fitted with limiting plates and limiting nuts. An insert plate is inserted into the slot, and multiple connecting rods are installed on one side of the insert plate, with a clamp fixed at one end of each connecting rod.

[0007] By adopting the above technical solution, when it is necessary to change different types of fixtures to adapt to different crafts, the staff can first rotate the limit nut so that the limit nut moves upward and no longer presses against the limit plate.

[0008] Furthermore, the base plate has two grooves inside, a motor is installed on one side of the base plate, and the output end of the motor is connected to a bidirectional lead screw extending into the groove.

[0009] By adopting the above technical solution, when it is necessary to clamp the handicraft, the motor can be started. The operation of the motor can drive the bidirectional lead screw to rotate, thereby driving the movable seat to move.

[0010] Furthermore, the bottom plate has sliding grooves on both sides of its top, and sliding seats are provided inside the sliding grooves.

[0011] By adopting the above technical solution, the slide block can slide inside the slide groove and drive the movable plate to move.

[0012] Furthermore, the outer wall of the bidirectional lead screw is fitted with two movable seats, the top of the movable seats is fixedly connected to the bottom of the slide, and the movable seats are threadedly connected to the bidirectional lead screw.

[0013] By adopting the above technical solution, when the bidirectional lead screw rotates, it will drive the two movable seats to move simultaneously, and the movable seats will then drive the slide to move, so as to adjust the position of the slide and the movable plate.

[0014] Furthermore, a movable plate is installed on the top of the slide block, and the movable plate is slidably connected to the slide groove through the slide block.

[0015] By adopting the above technical solution, when the slide block slides inside the slide groove, it will drive the movable plate to move, thereby improving the stability of the movable plate when it moves.

[0016] Furthermore, the insert plate is adapted to the slot, and the clamp is detachably connected to the movable plate through the insert plate and the slot.

[0017] By adopting the above technical solution, the insert plate can be positioned after it is inserted into the slot.

[0018] Furthermore, a protective pad is installed on the side of the clamp away from the movable plate, and the protective pad is made of rubber material.

[0019] By adopting the above technical solution, the protective pad can protect the surface of the handicraft and prevent the clamp from directly contacting the surface of the handicraft.

[0020] Furthermore, the assembly and disassembly assembly also includes two limiting grooves opened on the top of the insert plate, the limiting plate being located inside the limiting grooves, and the bottom of the limiting plate being in contact with the insert plate.

[0021] By adopting the above technical solution, the limiting plate can limit the insertion plate, prevent the insertion plate from moving inside the slot, and thus improve the stability of the insertion plate.

[0022] Furthermore, the bottom of the limiting nut is fitted with the top of the limiting plate.

[0023] By adopting the above technical solution, the limiting nut can tighten and limit the limiting plate, preventing the limiting plate from moving at will.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model, by incorporating a disassembly and assembly component, allows for easy replacement of different types of clamps to suit various crafts. Workers can first rotate the limiting nut to move it upwards, freeing it from pressing against the limiting plate. Then, the limiting plate is pushed upwards to move out of the limiting groove. Next, the limiting plate is rotated so it is no longer directly above the limiting groove, allowing the insert plate to be pulled upwards to remove it from the slot. This allows the clamp to be removed. When installing different clamps, simply insert the insert plate into the slot. First, push the limiting plate upwards, then rotate the limiting plate so that it is directly above the limiting groove. Then push the limiting plate into the limiting groove to clamp and limit the insertion plate. Next, rotate the limiting nut so that the bottom of the limiting nut is pressed against the top of the limiting plate, thus limiting the plate. This completes the replacement of the clamp. This method allows for quick disassembly and replacement of the clamp, is relatively simple to operate, and improves the applicability of the auxiliary mechanism so that it can clamp handicrafts of different shapes.

[0026] 2. This utility model incorporates a protective pad, which protects the surface of the craftwork and prevents the clamp from directly contacting the surface of the craftwork, thus avoiding wear and tear. Attached Figure Description

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0036] The embodiments of this utility model will be described below based on its overall structure.

[0037] Example 1:

[0038] A welding auxiliary mechanism for large metal crafts, such as Figures 1-7 As shown, the device includes a base plate 1 and two movable plates 8. A disassembly assembly 9 is provided on one side of each movable plate 8. Two grooves 2 are formed inside the base plate 1. A motor 4 is installed on one side of the base plate 1. The output end of the motor 4 is connected to a bidirectional lead screw 3 extending into the groove 2. When the craft needs to be clamped, the motor 4 can be started. The operation of the motor 4 drives the bidirectional lead screw 3 to rotate, thereby moving the movable seat 6. Slide grooves 5 are provided on both sides of the top of the base plate 1. Slide seats 7 are installed inside the slide grooves 5. The slide seats 7 can slide inside the slide grooves 5 and can move the movable plates. 8. The outer wall of the bidirectional lead screw 3 is fitted with two movable seats 6. The top of the movable seats 6 is fixedly connected to the bottom of the slide 7. The movable seats 6 are threadedly connected to the bidirectional lead screw 3. When the bidirectional lead screw 3 rotates, it will drive the two movable seats 6 to move simultaneously. The movable seats 6 will then drive the slide 7 to move, so as to adjust the position of the slide 7 and the movable plate 8. The movable plate 8 is installed on the top of the slide 7. The movable plate 8 is slidably connected to the slide groove 5 through the slide 7. When the slide 7 slides inside the slide groove 5, it will drive the movable plate 8 to move, thereby improving the stability of the movable plate 8 when it moves.

[0039] See Figures 1-6The assembly / disassembly component 9 includes slots 901 on one side of the two movable plates 8 and two threaded posts 905 installed on the top of the two movable plates 8. Limiting plates 907 and limiting nuts 906 are respectively fitted onto the outer walls of the threaded posts 905. Insert plates 902 are inserted into the slots 901, and multiple connecting rods 903 are installed on one side of the insert plates 902. A clamp 904 is fixed to one end of each connecting rod 903. When different types of clamps 904 need to be replaced to accommodate different crafts, the worker can first... Rotate the limiting nut 906 so that it moves upward and no longer presses against the limiting plate 907. The insert plate 902 is adapted to the slot 901. The clamp 904 is detachably connected to the movable plate 8 through the insert plate 902 and the slot 901. When the insert plate 902 is inserted into the slot 901, it can be positioned. The bottom of the limiting nut 906 fits against the top of the limiting plate 907. The limiting nut 906 can press against the limiting plate 907 to prevent it from moving at will.

[0040] Example 2;

[0041] Based on the above embodiment one, in order to avoid the fixture 904 from directly contacting the surface of the craft, the following structure will be set.

[0042] Specifically, a protective pad 908 is installed on the side of the clamp 904 away from the movable plate 8. The protective pad 908 is made of rubber material. The protective pad 908 can protect the surface of the craft and prevent the clamp 904 from directly contacting the surface of the craft.

[0043] Example 3:

[0044] Based on the above embodiment 1, in order to facilitate the limiting plate 907 to limit the insertion plate 902, the following structure will be set.

[0045] See Figure 1 , Figure 4 , Figure 6 and Figure 7 The assembly 9 also includes two limiting grooves 909 on the top of the insert plate 902. The limiting plate 907 is located inside the limiting groove 909. The bottom of the limiting plate 907 is in contact with the insert plate 902. After the limiting plate 907 moves into the limiting groove 909, it can limit the insert plate 902 and prevent the insert plate 902 from moving inside the slot 901, thereby improving the stability of the insert plate 902.

[0046] The working principle of this utility model is as follows: First, when using this auxiliary mechanism, the craft can be placed at the top center of the base plate 1. Then, the motor 4 is started. The operation of the motor 4 can drive the bidirectional lead screw 3 to rotate, thereby driving the two movable seats 6 to move simultaneously, and driving the slide 7 to move, then driving the movable plate 8 to move, and then driving the clamp 904 and the protective pad 908 to move, so that the clamp 904 and the protective pad 908 can clamp and fix the craft, preventing the craft from moving during the welding process and affecting the welding effect.

[0047] When it is necessary to change different types of clamps 904 to accommodate different crafts, the worker can first rotate the limiting nut 906 so that the limiting nut 906 moves upward and no longer presses against the limiting plate 907. Then, push the limiting plate 907 upward so that the limiting plate 907 moves out of the limiting groove 909. Then rotate the limiting plate 907 so that the limiting plate 907 is no longer directly above the limiting groove 909. Then, pull the insert plate 902 upward so that the insert plate 902 moves out of the slot 901, thereby removing the clamp 904 and installing different... When changing the fixture, simply insert the insert plate 902 into the slot 901, then push the limiting plate 907 upwards, and then rotate the limiting plate 907 so that it is directly above the limiting groove 909. Then push the limiting plate 907 into the limiting groove 909 to tighten and limit the insert plate 902. Next, rotate the limiting nut 906 so that the bottom of the limiting nut 906 is pressed against the top of the limiting plate 907, thereby limiting the limiting plate 907. This completes the replacement of the fixture 904.
