Description

Technical Field

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

[0002] Metal furniture is widely used in home, office, and commercial environments due to its sturdy structure, durability, and modern style. This type of furniture typically uses metal tubing, sheet metal, or profiles as its main structure, with columns, beams, and other components connected by welding to form an overall frame. The quality of the welding directly determines the product's strength, durability, and aesthetics.

[0003] In the early stages of metal furniture production, welding was mostly done manually, heavily reliant on the welder's personal experience and skills. This method was not only labor-intensive and inefficient, but also struggled to guarantee weld uniformity and consistency, making it unsuitable for large-scale production. As the industry developed, fixed or easily adjustable welding fixtures emerged, using cylinders or lead screws to clamp the workpiece. However, such equipment often lacked flexible orientation adjustment capabilities when dealing with multi-angle welds (such as welding the inner and outer corners of L-shaped metal parts), making it difficult to optimize the relative posture between the welding head and the workpiece, thus affecting weld quality.

[0004] Therefore, there is an urgent need for a welding device specifically designed for metal furniture production, capable of quickly aligning L-shaped metal parts and supporting the workpiece's adjustment in plane and around an axis, thereby ensuring that the weld seam is in the optimal welding posture throughout the entire process and improving welding strength and efficiency. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a metal welding device for furniture production and processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A metal welding device for furniture manufacturing and processing includes a welding mechanism for welding metal parts and a clamping mechanism for fixing the metal parts. The welding mechanism includes a mounting frame, on which a longitudinal moving component is mounted, and on which a lifting control seat is mounted for controlling the translation of the lifting control seat. A welding head for welding is mounted at the bottom of the lifting control seat. The clamping mechanism includes a clamping assembly for clamping metal parts, a rotation control assembly for controlling the rotation of the clamping assembly, and a lateral movement assembly for controlling the translation of the two clamping assemblies to achieve docking of the two metal parts. The movement directions of the lateral movement assembly and the longitudinal movement assembly are in a cross shape.

[0007] As a preferred embodiment of the present invention, the number of welding heads is two, and the two are arranged symmetrically.

[0008] As a preferred embodiment of the present invention, the clamping assembly includes: The support platform has a V-shaped structure at the top that fits the metal parts. When fixing, the angle of the L-shaped metal parts is adjusted so that they can fit against the V-shaped top surface of the support platform. The clamps are V-shaped structures adapted to the support platform. Multiple clamps are linearly distributed along the top of the support platform, and side supports are fixed to the sides of the clamps. The guide post has one end fixed to the support platform, and the side bracket is slidably connected to the outer wall of the guide post. The guide post and the side bracket are connected by a first spring.

[0009] As a preferred embodiment of the present invention: the top of the clamping plate is connected to a positioning cover via a connecting rod, the positioning cover having a funnel-shaped structure; a support base is installed inside the support platform, a connecting arm is fixed to the output end of the support base, a top rod is fixed to the connecting arm, the inner diameter of the positioning cover gradually decreases in the direction away from the connecting arm, and the size of multiple positioning covers gradually decreases in the direction away from the connecting arm; a positioning block is installed on the top rod to be sequentially adapted to each positioning cover, the positioning block having an ellipsoidal structure, the diameter of the positioning block gradually decreasing from the middle to both ends.

[0010] As a preferred embodiment of the present invention: the positioning block is provided with a cavity, the positioning block is slidably mounted on the outer wall of the top rod, an mounting plate is fixed on the outer side of the top rod, the mounting plate is located in the cavity of the positioning block, and the mounting plate and the positioning block are connected by a second spring.

[0011] As a preferred embodiment of the present invention: a fixed column is fixed to one side of the outer wall of the support platform, a positioning plate is slidably connected to the outer wall of the fixed column, and an adjusting stud is rotatably connected to the support platform, the adjusting stud being threaded to the inner wall of the positioning plate.

[0012] As a preferred embodiment of the present invention, the rotation control component includes: A support frame, on which a ring-shaped frame is fixed; A rotating frame, which is rotatably mounted inside the ring frame; A connecting rod, one end of which is fixed to the rotating frame, and the other end of which is fixed to the support platform; A rotation drive unit is mounted on a support frame and is used to drive the rotating frame to rotate.

[0013] As a preferred embodiment of the present invention, the rotation drive unit includes: Rotation drive motor, which is mounted on the support frame; The drive gear has circumferentially distributed convex teeth on the outer side of the rotating frame, and the drive gear meshes with the convex teeth.

[0014] As a preferred embodiment of the present invention, the lateral movement component includes: A base with a guide rod fixed on it, and a support frame slidably connected to the outer wall of the guide rod; A translation control motor is fixed on the base. A translation control screw is installed at the output end of the translation control motor. One end of the translation control screw is rotatably installed on the base. The support frame is threadedly connected to the outer wall of the translation control screw.

[0015] As a preferred embodiment of the present invention: a cutting mechanism is installed on one side of the mounting frame. The cutting mechanism includes an electric telescopic cylinder, which is mounted on the mounting frame. A support base is fixed to the output end of the electric telescopic cylinder. A hydraulic cylinder is mounted on the support base. A lifting frame is fixed to the hydraulic cylinder. A rotating shaft is rotatably mounted on the lifting frame. A cutting blade is mounted on the rotating shaft. A driven gear is mounted on the rotating shaft of the cutting blade. A cutting motor is mounted on the lifting frame. A driving gear is mounted to the output end of the cutting motor. The driving gear meshes with the driven gear.

[0016] The beneficial effects of this invention are as follows: 1. This invention, by setting up structures such as positioning covers and positioning blocks, enables the connecting arm to move based on the support base, thereby inserting the positioning blocks into the corresponding positioning covers to support them. Under the pressure and limiting effect of the mounting plates on the positioning covers, the clamping plates move towards the support platform under the guidance of the guide columns, thus clamping the metal parts. Since the size of the multiple positioning covers gradually decreases in the direction away from the connecting arm, and the positioning blocks are sequentially adapted to the positioning covers, it ensures that the smaller positioning blocks on the front side can smoothly pass through the larger positioning covers and extend into the corresponding positioning covers, thereby achieving the compression and fixation of multiple positioning covers. The use of multiple clamping plates enables better clamping and fixation.

[0017] 2. By setting up a positioning plate and other structures, the present invention can restrict one end of the metal part, thereby achieving the initial positioning of the metal part, so that the two metal parts can be accurately docked during subsequent alignment.

[0018] 3. By setting up a rotation control component, the present invention can drive the rotating frame to rotate, thereby driving the clamping component to rotate, so that the weld seam of the two mating metal parts is adjusted below the welding head, enabling the welding head to perform welding from all directions.

[0019] 4. Since the present invention is used for the butt joint of L-shaped metal parts, the weld seam is also L-shaped. One side of the L-shaped weld seam can be adjusted to a vertical state. The weld seam on this side can be welded simultaneously from two directions using two welding heads. Then, the structure is rotated to adjust the weld seam on the other side to a vertical state, thus completing the welding of the weld seam on the other side. There is no need to adjust the angle of the welding heads, thereby achieving omnidirectional welding. Attached Figure Description

Detailed Implementation

[0022] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0023] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. 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.

[0024] Example 1: A metal welding device for furniture manufacturing and processing, such as Figure 1-6 As shown, it is particularly suitable for butt welding of two L-shaped metal parts 14, including a welding mechanism for welding the metal parts 14 and a clamping mechanism for fixing the metal parts 14. The welding mechanism includes a mounting frame 1, on which a longitudinal moving component is mounted, and a lifting control seat 2 is mounted on the longitudinal moving component for controlling the translation of the lifting control seat 2. A welding head 36 for welding is mounted at the bottom end of the lifting control seat 2. The clamping mechanism includes a clamping assembly for clamping metal parts 14, a rotation control assembly for controlling the rotation of the clamping assembly, and a lateral movement assembly for controlling the translation of the two clamping assemblies to achieve docking of the two metal parts 14. The movement directions of the lateral movement assembly and the longitudinal movement assembly are in a cross shape.

[0025] For ease of welding; such as Figure 2 As shown, there are two welding heads 36, and the two are arranged symmetrically.

[0026] For ease of clamping and fixing; such as Figure 3 As shown, the clamping assembly includes: The support platform 23 has a V-shaped structure at the top that is adapted to the metal part 14. When fixing, the angle of the L-shaped metal part 14 is adjusted so that it can fit against the V-shaped top surface of the support platform 23. Clamping plate 17, clamping plate 17 has a V-shaped structure adapted to support platform 23, multiple clamping plates 17 are linearly distributed along the top of support platform 23, and side brackets 24 are fixed on the side of clamping plate 17. Guide post 16, one end of guide post 16 is fixed on support platform 23, side bracket 24 is slidably connected to the outer wall of guide post 16, and guide post 16 and side bracket 24 are connected by first spring 15. By setting up a clamping assembly, the metal part 14 to be welded can be placed between the support platform 23 and the clamping plate 17, and the metal part 14 can be clamped and fixed by multiple clamping plates 17.

[0027] For more stable clamping; such as Figure 3-5 As shown, the top of the clamping plate 17 is connected to a positioning cover 26 via a connecting rod. The positioning cover 26 has a funnel-shaped structure. A support base 27 is installed inside the support platform 23. A connecting arm 20 is fixed to the output end of the support base 27. A top rod 18 is fixed on the connecting arm 20. The inner diameter of the positioning cover 26 gradually decreases in the direction away from the connecting arm 20, and the size of multiple positioning covers 26 gradually decreases in the direction away from the connecting arm 20. A positioning block 30 is installed on the top rod 18 to be adapted to each positioning cover 26 in sequence. The positioning block 30 has an ellipsoidal structure, and the diameter of the positioning block 30 gradually decreases from the middle to both ends. By setting up structures such as positioning covers 26 and positioning blocks 30, the connecting arm 20 can be moved based on the support base 27, thereby inserting the positioning block 30 into the corresponding positioning cover 26 to support the positioning cover 26. Under the compression and limiting of the positioning cover 26 by the mounting plate 29, the clamping plate 17 is moved towards the support platform 23 under the guidance of the guide post 16, thereby clamping the metal part 14. Since the size of the multiple positioning covers 26 gradually decreases in the direction away from the connecting arm 20, and the positioning blocks 30 are adapted to the positioning covers 26 in sequence, it can be ensured that the small-sized positioning block 30 at the front can pass smoothly through the large-sized positioning cover 26 and extend into the corresponding positioning cover 26 to achieve compression and fixation of the multiple positioning covers 26. The setting of multiple clamping plates 17 can achieve better clamping and fixation.

[0028] For better clamping and fixation; such as Figure 5 As shown, the positioning block 30 has a cavity inside, and the positioning block 30 is slidably installed on the outer wall of the top rod 18. An mounting piece 29 is fixed on the outer side of the top rod 18. The mounting piece 29 is located in the cavity of the positioning block 30, and the mounting piece 29 and the positioning block 30 are connected by a second spring 28.

[0029] For ease of location; such as Figure 3 As shown, a fixing column 21 is fixed on one side of the outer wall of the support platform 23, and a positioning plate 19 is slidably connected to the outer wall of the fixing column 21. An adjusting stud 22 is rotatably connected to the support platform 23, and the adjusting stud 22 is threadedly connected to the inner wall of the positioning plate 19. By setting up structures such as positioning plate 19, one end of metal part 14 can be restricted, thereby achieving the initial positioning of metal part 14 so that the two metal parts 14 can be accurately aligned during subsequent alignment.

[0030] To facilitate control of the rotation of the clamping assembly; such as Figure 1-3 As shown, the rotation control assembly includes: Support frame 7, on which a ring frame 12 is fixed; Rotating frame 4 is rotatably mounted inside the ring frame 12; Connecting rod 25, one end of which is fixed to the rotating frame 4, and the other end of which is fixed to the support platform 23; A rotation drive unit is mounted on the support frame 7 and is used to drive the rotation frame 4 to rotate. By setting a rotation control component, the rotating frame 4 can be driven to rotate, which in turn drives the clamping component to rotate, thereby adjusting the position of the weld seam of the two mating metal parts 14 below the welding head 36, so that the welding head 36 can perform welding from all directions. In this process, since the metal parts 14 of the L-shaped structure are joined together, the weld seam is also L-shaped. One side of the L-shaped weld seam can be adjusted to a vertical state. The weld seam on this side can be welded simultaneously from two directions using two welding heads 36. Then, the structure is rotated to adjust the weld seam on the other side to a vertical state, thus completing the welding of the weld seam on the other side. There is no need to adjust the angle of the welding head 36, thereby achieving all-round welding.

[0031] The rotation drive unit includes: Rotation drive motor 13 is mounted on support frame 7; The drive gear 3 and the rotating frame 4 are provided with circumferentially distributed convex teeth on their outer sides, and the drive gear 3 meshes with the convex teeth.

[0032] To facilitate control of structural connections; such as Figure 1 , Figure 2 As shown, the lateral movement component includes: Base 5, guide rod 11 is fixed on base 5, support frame 7 is slidably connected to the outer wall of guide rod 11; Translation control motor 10 is fixed on base 5. Translation control screw 6 is installed at the output end of translation control motor 10. One end of translation control screw 6 is rotatably installed on base 5. Support frame 7 is threadedly connected to the outer wall of translation control screw 6.

[0033] For ease of cutting; such as Figure 1 As shown, a cutting mechanism is installed on one side of the mounting frame 1. The cutting mechanism includes an electric telescopic cylinder 9, which is mounted on the mounting frame 1. A support base 27 is fixed to the output end of the electric telescopic cylinder 9. A hydraulic cylinder 35 is mounted on the support base 27. A lifting frame 31 is fixed to the hydraulic cylinder 35. A rotating shaft is rotatably mounted on the lifting frame 31. A cutting blade 8 is mounted on the rotating shaft. A driven gear 32 is mounted on the rotating shaft of the cutting blade 8. A cutting motor 34 is mounted on the lifting frame 31. A driving gear 33 is mounted to the output end of the cutting motor 34. The driving gear 33 meshes with the driven gear 32.

[0035] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
