Description

Technical Field

[0001] This invention relates to the field of metal parts processing technology, and in particular to a metal parts welding equipment for furniture production. Background Technology

[0002] As people's quality of life continues to improve, the furniture market is showing a diversified and personalized development trend. Modern furniture not only pursues novelty and uniqueness in appearance design, but also puts forward more stringent requirements for the structural strength, durability and overall quality of products. Metal support legs are increasingly widely used in furniture manufacturing due to their high strength, good stability and diverse styling possibilities.

[0003] Existing metal support leg welding equipment for furniture production was designed specifically for a single specification of metal support leg. This means that the equipment can only be used for welding specific specifications of metal support legs. Once the specifications of the metal support legs change during actual production, the equipment can no longer operate effectively and cannot flexibly adapt to diverse production needs, causing many inconveniences in actual production. Summary of the Invention

[0004] This invention relates to a metal welding equipment for furniture production. To adapt to the processing needs of metal plates of different specifications, the spacing between the four positioning posts can be changed according to the specific specifications of the metal plate, ensuring that the positioning posts can be accurately inserted into the corresponding connection holes of the metal plate, thereby achieving effective positioning and fixing of the metal plate. Based on the actual needs of metal legs of different specifications, the arched pressure piece can be flexibly raised and lowered to form a stable clamping and fixing of the metal leg, effectively ensuring the welding accuracy of the contact part between the metal leg and the metal plate, and better meeting the welding processing needs of support legs of different specifications of furniture.

[0005] In a first aspect, this invention provides a metal welding device for furniture production, specifically comprising: a base support, movable rocker arms, a movable gear ring, transmission rods, a top support plate, an outer casing, a lower connecting plate, an arched pressure member, and a tension spring; four movable rocker arms are mounted around the top of the base support, and positioning posts are provided on the top of the movable rocker arms; the movable gear ring is mounted on the top of the base support, and four transmission rods are connected inside the movable gear ring, the transmission rods being connected to the movable rocker arms; a top support plate is mounted on the top of the base support, and the bottom side of the top support plate contacts the top side of the movable gear ring; the positioning posts penetrate through the interior of the top support plate and are inserted into connecting holes in the metal plate; an outer casing is connected to the top of the base support, and the outer casing is connected to the movable gear ring; two lower connecting plates are fixedly mounted on the top of the outer casing, and an arched pressure member is connected to the top of the lower connecting plate, with two tension springs connected to the outside of the arched pressure member; a stepped plate is arranged around the bottom side of the arched pressure member, and the stepped plate contacts the metal legs.

[0006] Furthermore, the movable rocker arm is rotatably connected to the bottom support base, and the top support plate is provided with a movable arc hole around its interior. The positioning pin is slidably connected in the movable arc hole. The movable rocker arm can be rotated and adjusted according to the different specifications of the metal plate to change the spacing between the four positioning pins, so that the positioning pins can be inserted into the connecting holes of the metal plate, thereby achieving the effect of limiting and fixing the metal plate.

[0007] Furthermore, the movable gear ring is rotatably connected to the bottom support base, and a limit rod is provided on the top of the bottom support base. An arc-shaped guide hole is arranged around the inside of the movable gear ring, and the limit rod is slidably connected in the arc-shaped guide hole. One end of the limit rod is rotatably connected to the movable rocker arm, and the other end of the limit rod is rotatably connected to the movable gear ring. When the fixed gear ring is rotated, the fixed gear ring drives the four movable rockers to rotate synchronously through the limit rod, ensuring the synchronicity of the movement adjustment of the four positioning columns.

[0008] Furthermore, a fixed gear ring is provided on the top of the bottom support, and the tooth groove of the fixed gear ring matches the tooth groove of the movable gear ring. A toothed sleeve is provided inside the outer shell, and the toothed sleeve is slidably connected to the outside of the movable gear ring and the fixed gear ring. When it is necessary to adjust the positioning column, the outer shell is moved upward to separate the toothed sleeve from the fixed gear ring, the rotation lock of the outer shell is released, and the movable gear ring is driven to rotate through the outer shell to realize the positioning column adjustment operation.

[0009] Furthermore, the outer casing is provided with two arc-shaped sliding holes, and the top of the bottom support is provided with two guide rods, which are slidably connected in the arc-shaped sliding holes.

[0010] Furthermore, a return spring and a washer are fitted outside the guide rod. The washer is slidably connected to the guide rod. The top of the return spring contacts the top of the guide rod, the bottom of the return spring contacts the top side of the washer, and the bottom side of the washer slides in contact with the top side of the outer casing. When the outer casing is moved upward, the return spring contracts under force. After the positioning post is adjusted to the required position, the fixed gear ring stops rotating, and the tooth groove of the fixed gear ring and the tooth groove of the moving gear ring are in a matching state. When the outer casing is released, the outer casing moves downward to reset under the influence of the return spring, so that the gear sleeve meshes with the fixed gear ring. The outer casing locks and fixes the moving gear ring, preventing the moving gear ring from rotating, thus fixing the positioning post.

[0011] Furthermore, the arched pressure member is slidably connected to the lower connecting plate. The lower connecting plate has a downward sliding hole inside, and the arched pressure member has an upper sliding block outside. The upper sliding block is slidably connected to the downward sliding hole. The lower connecting plate has a lower sliding block outside, and the arched pressure member has an upper sliding hole inside. The lower sliding block is slidably connected to the upper sliding hole.

[0012] Furthermore, the lower connecting plate is provided with a lower connecting hole on its exterior, and the lower end of the storage spring is connected to the lower connecting hole. The arched pressing component is provided with an upper connecting hole on its exterior, and the upper end of the storage spring is connected to the upper connecting hole. The arched pressing component can be raised and lowered according to the different specifications of the metal leg. When the metal leg is placed on top of the metal plate, the metal leg and the metal plate form the furniture support leg. When the arched pressing component is released, it moves downward under the influence of the storage spring, so that the step plate contacts the metal leg and clamps and fixes the metal leg, ensuring the welding accuracy of the contact part between the metal leg and the metal plate.

[0013] This invention provides a metal welding device for furniture manufacturing, which has the following advantages:

[0014] In use, to adapt to the processing requirements of metal plates of different specifications, the movable rocker arm can be rotated to adjust its angle according to the specific specifications of the metal plate, thereby changing the interval between the four positioning posts. This ensures that the positioning posts can be accurately inserted into the corresponding connection holes of the metal plate, achieving effective positioning and fixing of the metal plate, and fully meeting the usage requirements in various furniture support leg welding processing scenarios. The limiting rod and the arc-shaped guide hole adopt a sliding fit design, which can accurately limit the rotation angle range of the moving gear ring, ensuring that the moving gear ring rotates stably within the specified range. When the fixed gear ring is rotated, the fixed gear ring drives the four movable rocker arms to rotate synchronously with the help of the limiting rod, thereby ensuring the high synchronization of the four positioning posts during the movement and adjustment process.

[0015] Furthermore, when adjusting the positioning pin, pull the outer sleeve upwards to separate the gear sleeve from the fixed gear ring. At this time, the rotation lock of the outer sleeve is released, and the movable gear ring can be rotated by the outer sleeve to smoothly carry out the adjustment of the positioning pin. During the upward movement of the outer sleeve, the return spring is compressed by external force. After the positioning pin is adjusted to the target position, stop rotating the fixed gear ring. At this time, the tooth groove of the fixed gear ring and the tooth groove of the movable gear ring are precisely matched. Release the outer sleeve, and the outer sleeve will automatically move downwards to reset under the elastic thrust of the return spring, so that the gear sleeve and the fixed gear ring re-engage. By locking and fixing the movable gear ring with the outer sleeve, the rotation of the movable gear ring is effectively prevented, thereby achieving a stable fixation of the positioning pin and fully ensuring the stability of the positioning pin.

[0016] Furthermore, the structural design employs a sliding cooperation between the upper slider and the lower sliding hole, and the lower slider and the upper sliding hole, providing precise movement guidance for the arched pressure component. A tension spring is configured to achieve the elastic reset function of the arched pressure component. Based on the actual needs of different specifications of metal legs, the arched pressure component can be flexibly adjusted in height. During welding operations, when the metal leg is placed on top of the metal plate, together forming the furniture support leg, the operator releases the arched pressure component. Under the tension of the tension spring, the arched pressure component automatically moves downward until the step plate and the metal leg are in close contact, thus forming a stable clamping and fixing of the metal leg. This effectively ensures the welding accuracy of the contact area between the metal leg and the metal plate, and can better meet the welding processing needs of different specifications of furniture support legs.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Please refer to Figures 1 to 8 Example 1:

[0043] This invention proposes a metal welding device for furniture production, comprising: a base support 1, movable rocker arms 2, a moving gear ring 3, a transmission rod 4, a top support plate 5, an outer casing 6, a lower connecting plate 9, an arched pressing component 10, and a tension spring 11; four movable rocker arms 2 are mounted around the top of the base support 1, and positioning posts 201 are provided on the top of the movable rocker arms 2; the moving gear ring 3 is mounted on the top of the base support 1, and four transmission rods 4 are connected inside the moving gear ring 3, with the transmission rods 4 connected to the movable rocker arms 2; the top support plate 5 is mounted on the top of the base support 1, and the bottom side of the top support plate 5 contacts the top side of the moving gear ring 3; the positioning posts 201 penetrate the interior of the top support plate 5 and are inserted into the connecting holes of the metal plate; the outer casing 6 is connected to the top of the base support 1, and the outer casing 6 is connected to the moving gear ring 3. The outer casing 6 has two lower connecting plates 9 fixedly installed on its top. The top of the lower connecting plates 9 is connected to an arched pressure member 10, and the arched pressure member 10 is externally connected to two tension springs 11. A step plate 1001 is arranged around the bottom side of the arched pressure member 10, and the step plate 1001 contacts the metal leg. The movable rocker arm 2 is rotatably connected to the bottom support 1. The top support plate 5 has a movable arc hole 501 arranged around its interior, and the positioning post 201 is slidably connected in the movable arc hole 501. The movable rocker arm 2 can be rotated and adjusted according to the different specifications of the metal plate to change the spacing between the four positioning posts 201, so that the positioning posts 201 can be inserted into the connecting holes of the metal plate, thereby limiting and fixing the metal plate. This is more suitable for the welding and processing of support legs of different specifications of furniture.

[0044] In this embodiment, the movable gear ring 3 is rotatably connected to the bottom support 1. The bottom support 1 is provided with a limit rod 101 at the top. The movable gear ring 3 is surrounded by an arc-shaped guide hole 301. The limit rod 101 is slidably connected in the arc-shaped guide hole 301. One end of the limit rod 101 is rotatably connected to the movable rocker arm 2, and the other end of the limit rod 101 is rotatably connected to the movable gear ring 3.

[0045] Using the above technical solution, the rotation angle of the moving gear ring 3 is limited by the sliding engagement of the limiting rod 101 and the arc-shaped guide hole 301; when the fixed gear ring 103 is rotated, the fixed gear ring 103 drives the four movable rocker arms 2 to rotate synchronously through the limiting rod 101, ensuring the synchronicity of the movement adjustment of the four positioning columns 201.

[0046] In this embodiment, a fixed toothed ring 103 is provided on the top of the bottom support 1. The tooth groove of the fixed toothed ring 103 matches the tooth groove of the movable toothed ring 3. A toothed sleeve 601 is provided inside the outer shell sleeve 6. The toothed sleeve 601 is slidably connected to the outside of the movable toothed ring 3 and the fixed toothed ring 103.

[0047] Using the above technical solution, when it is necessary to adjust the positioning column 201, the outer shell sleeve 6 is moved upward to separate the gear sleeve 601 from the fixed gear ring 103. The outer shell sleeve 6 is released from rotation lock, and the moving gear ring 3 is rotated through the outer shell sleeve 6 to realize the adjustment operation of the positioning column 201.

[0048] In this embodiment, the outer shell 6 is provided with two arc-shaped sliding holes 602, and the bottom support 1 is provided with two guide rods 102. The guide rods 102 are slidably connected in the arc-shaped sliding holes 602. The guide rods 102 are fitted with a return spring 7 and a washer 8. The washer 8 is slidably connected to the guide rod 102. The top of the return spring 7 is in contact with the top of the guide rod 102, the bottom of the return spring 7 is in contact with the top side of the washer 8, and the bottom side of the washer 8 is in slidable contact with the top side of the outer shell 6.

[0049] Using the above technical solution, when the outer casing 6 is moved upward, the return spring 7 contracts under force. After the positioning post 201 is adjusted to the required position, the fixed gear ring 103 stops rotating. The tooth groove of the fixed gear ring 103 and the tooth groove of the moving gear ring 3 are in a matching state. When the outer casing 6 is released, the outer casing 6 moves downward to reset under the influence of the push of the return spring 7, so that the gear sleeve 601 is engaged with the fixed gear ring 103. The outer casing 6 locks and fixes the moving gear ring 3, preventing the moving gear ring 3 from rotating, thus fixing the positioning post 201 and ensuring the stability of the positioning post 201.

[0050] In Example 2, based on Example 1, the arched pressure member 10 is slidably connected to the lower connecting plate 9. The lower connecting plate 9 has a sliding hole 901 inside, and an upper slider 1002 is provided outside the arched pressure member 10. The upper slider 1002 is slidably connected to the sliding hole 901. The lower connecting plate 9 has a lower slider 902 outside, and an upper sliding hole 1003 is provided inside the arched pressure member 10. The lower slider 902 is slidably connected to the upper sliding hole 1003. The lower connecting plate 9 has a lower connecting hole 903 outside, and the lower end of the storage spring 11 is connected to the lower connecting hole 903. The arched pressure member 10 has an upper connecting hole 1004 outside, and the upper end of the storage spring 11 is connected to the upper connecting hole 1004.

[0051] Using the above technical solution, the upper slider 1002 slides into the lower sliding hole 901, and the lower slider 902 slides into the upper sliding hole 1003, to guide the movement of the arched pressure member 10. The tension spring 11 provides an elastic reset effect for the arched pressure member 10. The arched pressure member 10 can be adjusted in height according to the different specifications of the metal leg. When the metal leg is placed on top of the metal plate, the metal leg and the metal plate form a furniture support leg. When the arched pressure member 10 is released, it moves downward under the pull of the tension spring 11, so that the step plate 1001 contacts the metal leg, clamping and fixing the metal leg. This ensures the welding accuracy of the contact area between the metal leg and the metal plate, and is better suited for the welding processing of support legs of different specifications of furniture.

[0052] The working principle of this embodiment is as follows: First, according to the different specifications of the metal plate, the outer shell sleeve 6 is moved upward. The return spring 7 is compressed under force, and the toothed sleeve 601 separates from the fixed toothed ring 103. The outer shell sleeve 6 is released from rotational lock. The outer shell sleeve 6 drives the moving toothed ring 3 to rotate. The fixed toothed ring 103 drives the four movable rocker arms 2 to rotate synchronously through the limiting rod 101, changing the spacing between the four positioning pins 201, so that the positioning pins 201 can be inserted into the connecting holes of the metal plate, thereby achieving the effect of limiting and fixing the metal plate. After the positioning pins 201 are adjusted to the required position, the fixed toothed ring 103 stops rotating. The tooth groove of the fixed toothed ring 103 is in a matching state with the tooth groove of the moving toothed ring 3. The outer shell sleeve 6 is released, and the outer shell sleeve 6 is pushed by the return spring 7. The downward movement resets the position, engaging the toothed sleeve 601 with the fixed toothed ring 103. The outer sleeve 6 locks and fixes the movable toothed ring 3, preventing its rotation and thus securing the positioning post 201, ensuring its stability. When the worker pulls the arched pressure piece 10 upwards, the tension spring 11 is stretched. When the metal leg is placed on top of the metal plate, the metal leg and the metal plate form a furniture support leg. Releasing the arched pressure piece 10 causes it to move downwards under the tension of the tension spring 11, bringing the step plate 1001 into contact with the metal leg. This clamps and fixes the metal leg, allowing it to be welded to the metal plate, making it more suitable for welding support legs of different specifications of furniture.
