Technical Field
[0001] This invention relates to the field of table component technology, and in particular to a highly stable table component assembly equipment and process. Background Technology
[0002] Countertops are an essential piece of furniture in our lives. In our daily indoor and outdoor work and living environments, we set up countertops such as tables, coffee tables, TV cabinets, and dining tables to facilitate work and life. These configurations all share the common feature of being composed of supporting components and countertops. The supporting components must be sturdy and stable, and the countertops must have appropriate resistance to bending and deformation. Currently, table supporting components mostly use square tubes and beams to form a frame to support the countertop.
[0003] However, in actual use, the inventors found that the crossbeam is usually fixed to the upper outer wall of the table leg by bolts or welding. The pressure borne by the crossbeam can only be applied to the table leg through the bolts or welds. The bolts or welds are subjected to force for a long time, which can easily cause the upper outer wall of the table leg to deform and crack, resulting in an unstable tabletop.

[0016] The beneficial effects of this invention are: (1) In this invention, by combining the cutting mechanism and the welding mechanism, on the one hand, the triangular iron connector can be automatically welded to the notch at the upper end of the square tube.

It has high strength, long service life, and more solid support platform. On the other hand, when welding the triangular iron connector at the notch at the upper end of the square tube, the triangular iron connector can be positioned so that the triangular iron connector is tightly connected with the notch, preventing the triangular iron connector from shifting during the welding process, ensuring the stability of the welding work, and improving the welding effect of the triangular iron connector. (2) In this invention, by combining the corner-cutting component and the welding component, on the one hand, corner-cutting work can be carried out on the upper end of the square tube in both vertical and horizontal directions at the same time, which shortens the corner-cutting time and improves the corner-cutting efficiency of the square tube; on the other hand, the cut-off triangular plate can be reused. The triangular plate is welded to the lower end of the square tube by the pull rod. When the square tube is used as a table leg to support the table surface, the pull rod is manually pushed to move the triangular plate away from the lower end of the square tube. The triangular plate forms a fulcrum with the ground, which expands the support range of the lower end of the square tube with the ground and makes the table surface more stable.

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0040] Example 1 like Figures 1-19 As shown, a high-stability table component assembly equipment includes a conveying mechanism 1, and a feeding mechanism 2, a punching mechanism 3, a cutting mechanism 4, and a welding mechanism 5 disposed on one side of the conveying mechanism 1. The welding mechanism 5 includes a feeding assembly 51, a positioning assembly 52 disposed on the feeding assembly 51, and a welding assembly 53 disposed on the feeding assembly 51; The positioning component 52 includes a lifting plate 521 that is elastically and vertically mounted on the feeding component 51, two sets of positioning rods 522 mounted on the lifting plate 521, and a first limiting track 523 mounted on the feeding component 51 for driving the lifting plate 521 to rise with the positioning rods 522. The conveying mechanism 1 sequentially conveys the square tube 6 to the position of the welding mechanism 5. The feeding component 51 automatically pushes a single triangular iron connector 61 to the notch 62 at the upper end of the square tube 6. The positioning rod 522 rises and inserts into the mounting hole 63 of the triangular iron connector 61, positioning the triangular iron connector 61 at the notch 62 at the upper end of the square tube 6. The welding component 53 welds the triangular iron connector 61 to the notch 62 at the upper end of the square tube 6.
[0041] It should be noted that the table component in this invention uses square tubes as table legs to support the tabletop. The triangular iron connectors on the four square tubes are connected by horizontal bolts to form a support frame for supporting the tabletop, and the tabletop is installed on the support frame by bolts.
[0042] It is worth mentioning that the square tube is made of hollow steel tubing with a square cross-section.
[0043] In this embodiment, the cutting mechanism 4 and welding mechanism 5 work together to automatically weld the triangular iron connector 61 to the notch 62 at the upper end of the square tube 6. The crossbeam is installed at the upper end of the square tube 6 through the triangular iron connector to form a support platform frame. The notch 62 at the upper end of the square tube 6 can support the triangular iron connector, so that the square tube has the force to directly support the crossbeam, avoiding deformation and cracking of the side wall at the upper end of the square tube. This results in higher strength, longer service life, and a more solid support platform. On the other hand, when welding the triangular iron connector 61 at the notch 62 at the upper end of the square tube 6, the triangular iron connector 61 can be positioned so that it is tightly connected to the notch 62, preventing displacement of the triangular iron connector during welding, ensuring the stability of the welding work, and improving the welding effect of the triangular iron connector.
[0044] In detail, the conveying mechanism 1 intermittently feeds the bearing seat 131 to the workstations of the feeding mechanism 2, the drilling mechanism 3, the cutting mechanism 4, and the welding mechanism 5 in sequence. The feeding mechanism 2 releases a single square tube onto the bearing seat 131. The drilling mechanism 3 drills welding holes 64 at the corners of the upper end of the square tube and through holes 65 at the diagonal corners of the lower end of the square tube. The corner cutting assembly 41 cuts off the corners with welding holes 64 at the upper end of the square tube 6, forming a notch 62 for installing the triangular iron connector 61. The scrap material cut off is a triangular plate 66. The transfer assembly 42 sends the triangular plate 66 produced by the corner cutting work to the lower end of the square tube. The welding assembly... Part 43 drives a pull rod 67 to pass through the through hole 65 at the lower end of the square tube, and then insert it into the welding hole 64 of the triangle plate 66. Then, one end of the pull rod 67 is welded to the welding hole 64 of the triangle plate 66, thereby welding the triangle plate 66 to the lower end of the square tube 6 through the pull rod 67. Then, the feeding assembly 51 feeds a triangle iron connector to the notch 62 at the upper end of the square tube 6. The positioning assembly 52 positions the triangle iron connector, and the welding assembly 53 welds the triangle iron connector to the notch 62 at the upper end of the square tube 6, completing the assembly of the table components. Finally, the square tube is removed from the support 131 for subsequent work.
[0045] Furthermore, such as Figures 5-6 As shown, the conveying mechanism 1 includes an annular conveyor belt 12 mounted on the frame 11 and several sets of bearing assemblies 13 mounted on the annular conveyor belt 12. The bearing assembly 13 includes: The support seat 131 is disposed on the annular conveyor belt 12, and a buffer pad is disposed on the support seat 131; Upright poles 132, two sets of upright poles 132 are symmetrically arranged diagonally on the buffer pad, and are used to limit the square tube to stand on the buffer pad of the bearing seat 131.
[0046] It should be noted that the circular conveyor belt 12 is driven by an existing drive source, intermittently feeding the carrier 131 to the workstations of the feeding mechanism 2, the punching mechanism 3, the cutting mechanism 4, and the welding mechanism 5 in sequence.
[0047] In this embodiment, the conveying mechanism 1 can carry the square tube between various workstations and limit the square tube to ensure that it is always in a vertical state, without shifting or tilting, thus ensuring the accuracy of the assembly work.
[0048] In detail, the square tube is placed vertically on the buffer pad of the bearing seat 131, and the two uprights 132 are positioned diagonally inside the square tube to limit its movement. The annular conveyor belt 12 drives the bearing seat 131 to move the square tube to the work stations of the drilling mechanism 3, the cutting mechanism 4, and the welding mechanism 5.
[0049] Furthermore, such as Figures 7-8As shown, the feeding mechanism 2 is used to sequentially feed square tubes onto the supporting assembly 13. The feeding mechanism 2 includes: The second feeding channel 21 is provided on the frame 11, and square tubes are placed vertically inside the second feeding channel 21 in sequence; The second push plate 22 is slidably disposed inside the second feeding channel 21, and a third elastic element 23 is provided between the second push plate 22 and the inner wall of the second feeding channel 21. The material discharge port 24 is located at the bottom of the second feeding channel 21, and the square tube matches the interior of the material discharge port 24. A belt 25 is rotatably mounted on the outer wall of the second feeding channel 21. Several sets of anti-slip blocks 26 are provided on the belt 25. The anti-slip blocks 26 are used to drive the square tube at the discharge port 24 to descend onto the bearing assembly 13. A first stepper motor for driving the belt 25 is provided on the outer wall of the second feeding channel 21. The lower guide bar hole 27 is opened on the side wall of the second feeding channel 21, and its lower end extends to the discharge port 24. The belt 25 is disposed inside the lower guide bar hole 27.
[0050] In this embodiment, the feeding mechanism 2 can automatically release a single square tube from the support seat 131, which is highly automated and ensures orderly feeding.
[0051] In detail, when the support seat 131 moves to the position below the discharge port 24 of the second feeding channel 21, the second push plate 22, driven by the third elastic element 23, pushes the square tube inside the second feeding channel 21 to the position of the discharge port 24. The belt 25 starts to rotate, and the anti-slip block 26 on the belt 25 drives a square tube at the discharge port 24 to fall onto the support seat 131. Then, the belt 25 stops rotating, and the second push plate 22 continues to push a square tube to the position of the discharge port 24. The anti-slip block 26 on the belt 25 contacts the outer wall of the square tube at the discharge port 24. At the same time, relying on the lateral pressure of the adjacent square tube, the square tube at the discharge port 24 will not fall when the belt 25 stops rotating.
[0052] Furthermore, such as Figure 5 and Figure 9 As shown, the punching mechanism 3 includes: A first horizontal drive unit 31 is disposed on the frame 11; The upper extension plate 32 is disposed at the output end of the first horizontal drive unit 31. The upper extension plate 32 is provided with a first drill rod 33 and a second drill rod 34. The first drill rod 33 is used to open a welding hole 64 at the corner of the upper end of the square tube, and the second drill rod 34 is used to open a through hole 65 at the corner of the lower end of the square tube.
[0053] It should be noted that the upper extension plate 32 is equipped with two sets of second stepper motors, which are used to drive the first drill rod 33 and the second drill rod 34 to work respectively.
[0054] It is worth mentioning that the first horizontal drive unit 31 and the second horizontal drive unit 411 have the same structure, including a lead screw, a threaded block and a motor. The motor drives the lead screw to rotate, and the lead screw drives the threaded block to move horizontally.
[0055] In this embodiment, the drilling mechanism 3 can simultaneously open welding holes 64 at the corners of the upper end of the square tube and through holes 65 at the corners of the lower end of the square tube, which facilitates the subsequent welding work of the triangular plate and the lower end of the square tube.
[0056] In detail, when the support seat 131 carries the square tube to the work position of the drilling mechanism 3, the first horizontal drive unit 31 drives the first drill rod 33 and the second drill rod 34 to move towards the corner of the square tube. The first drill rod 33 opens a welding hole 64 at the corner of the upper end of the square tube, and the second drill rod 34 opens a through hole 65 at the corner of the lower end of the square tube.
[0057] Furthermore, such as Figure 5 and Figures 10-16 As shown, the cutting mechanism 4 includes a corner-cutting assembly 41 mounted on the frame 11 for cutting the upper end of the square tube, a transfer assembly 42 mounted on the corner-cutting assembly 41 for conveying the triangular plate 66 generated during the corner-cutting work to the lower end of the square tube, and a welding assembly 43 mounted on the corner-cutting assembly 41 for welding the triangular plate 66 to the lower end of the square tube 6 via a pull rod 67. The chamfering component 41 cuts off the corner with welding hole 64 at the upper end of the square tube 6 to form a notch 62 for installing the triangular iron connector 61. The cut-off waste is a triangular plate 66. The chamfering component 41 includes: The second horizontal drive unit 411 is disposed on the frame 11; L-shaped plate 412, wherein the L-shaped plate 412 is disposed at the output end of the second horizontal drive unit 411; The first corner guard plate 413 is disposed on the L-shaped plate 412. The first corner guard plate 413 is adapted to the corner of the square tube. The upper end of the first corner guard plate 413 is provided with a second corner guard plate 415 through two sets of U-shaped frames 414. The two sets of landing blocks 416 are respectively lifted and mounted on the two sets of U-shaped frames 414 via a third hydraulic component 417, and a crank 418 is provided between the two sets of landing blocks 416. The first cutting unit 419, two sets of the first cutting units 419 are respectively disposed on the falling block 416, and are used to vertically cut the notch 62 at the upper end of the square tube 6; The two sets of slide rails are respectively installed on both sides of the upper end of the first corner guard plate 413; A column 4191 is slidably mounted on the slide rail, and a first upright plate 4192 is slidably mounted on the column 4191. The second cutting unit 4193 is disposed on the first upright plate 4192 and is used to cut the notch 62 at the upper end of the square tube 6 in the horizontal direction along the gap between the first corner guard plate 413 and the second corner guard plate 415. The first slope plate 4194 is disposed at the upper end of the first vertical plate 4192. The crank 418 drives the first vertical plate 4192 to move the second cutting unit 4193 toward the side wall of the square tube through the first slope plate 4194. A limiting block is slidably disposed on both sides of the upper end of the second corner guard plate 415. An outer edge rod 4195 is provided on the limiting block. The first slope plate 4194 is slidably disposed on the outer edge rod 4195. A fourth elastic element is provided between one end of the outer edge rod 4195 and the first slope plate 4194. The first rack 4196 is disposed on the post 4191; The first gear 4197 is rotatably mounted on the first corner guard plate 413 and is used to drive the first rack 4196 to move horizontally with the second cutting unit 4193 through the bar post 4191. The second gear 4198 is coaxially mounted on the first gear 4197; The second rack 4199 is disposed on the crank 418 and is used to drive the second gear 4198 to rotate synchronously with the first gear 4197.
[0058] It should be noted that the first cutting unit 419 and the second cutting unit 4193 have the same structure and adopt the water cutting or gas cutting method in the prior art. Both the first cutting unit 419 and the second cutting unit 4193 are cutting heads, and the existing host is set on the frame 11.
[0059] It is worth mentioning that when it is necessary to cut the corner of the square tube, the second horizontal drive unit 411 drives the first corner guard plate 413 to move towards the corner of the square tube. The first corner guard plate 413 and the second corner guard plate 415 stop near the corner of the square tube. At this time, the distance between the inner wall of the first corner guard plate 413 and the inner wall of the second corner guard plate 415 and the side wall of the square tube is exactly equal to the thickness of the triangle plate 66, that is, the side wall thickness of the square tube. This makes it convenient for the cut triangle plate 66 to fall along the gap between the first corner guard plate 413 and the square tube, and also ensures that the triangle plate 66 can fit against the corner of the lower end of the square tube.
[0060] It should also be noted that when the first cutting unit 419 cuts the notch 62 at the upper end of the square tube 6 in the vertical direction, the two sets of first cutting units 419 move downward from the middle position at the top of the side wall of the square tube.
[0061] It is also worth mentioning that when the second cutting unit 4193 cuts the notch 62 at the upper end of the square tube 6 in the horizontal direction, one set of the second cutting units 4193 moves from the middle position of the side of the upper end of the square tube to the corner of the square tube, and the other set of the second cutting units 4193 moves from the corner of the square tube to the middle position of the side of the square tube, ensuring that the two sets of second cutting units 4193 do not interfere with each other.
[0062] In this embodiment, by combining the chamfering component 41 and the welding component 43, on the one hand, the chamfering work on the upper end of the square tube can be performed simultaneously in the vertical and horizontal directions, shortening the chamfering time and improving the chamfering efficiency of the square tube; on the other hand, the cut-off triangular plate can be reused. The triangular plate is welded to the lower end of the square tube by the pull rod 67. When the square tube is used as a table leg to support the tabletop, the pull rod 67 can be manually pushed to move the triangular plate away from the lower end of the square tube. The triangular plate forms a fulcrum with the ground, expanding the support range between the lower end of the square tube and the ground, making the tabletop more stable.
[0063] In detail, when the support seat 131 carrying the square tube moves to the work position of the cutting mechanism 4, the second horizontal drive unit 411 drives the first corner guard plate 413 to move towards the corner of the square tube. The first corner guard plate 413 and the second corner guard plate 415 stop near the corner of the square tube. The third hydraulic component 417 drives the lowering block 416 to descend with the two sets of first cutting units 419, so that the two sets of first cutting units 419 move downward from the middle position of the top of the side wall of the square tube and cut corners in the vertical direction. At the same time, the crank rod 418 drives the first vertical plate 4192 to move with the second cutting unit 4193 towards the square tube through the first slope plate 4194. When the crank rod 418 approaches the square tube, the second rack 4199 on the crank rod 418 drives the second gear 4198 to rotate synchronously with the first gear 4197. 7. The first rack 4196 is driven to move horizontally along the second cutting unit 4193 via the bar column 4191. This causes one set of second cutting units 4193 to move from the middle of the side of the square tube to the corner of the square tube, while the other set of second cutting units 4193 moves from the corner of the square tube to the middle of the side of the square tube. This cuts the corner horizontally until the cutting is completed, forming a notch at the upper end of the square tube. Then, the third hydraulic component 417 drives the lowering block 416 to rise and reset the two sets of first cutting units 419. The second rack 4199 on the crank 418 drives the two sets of second cutting units 4193 to reset. After the crank 418 rises and disengages from the first slope plate 4194, the fourth elastic component drives the first slope plate 4194 to move the second cutting unit 4193 away from the square tube and reset it for the next use.
[0064] Furthermore, such as Figures 10-12 and Figure 16 As shown, the transmission component 42 includes: A fixing rod 421 is provided at the corner of the second corner guard plate 415; The second slope plate 422 is slidably disposed on the fixed rod 421, and a fifth elastic element 423 is provided between one end of the fixed rod 421 and the second slope plate 422. The second upright plate 424 is mounted on the second slope plate 422. A first vacuum suction cup 425 is mounted on the second upright plate 424 via a connecting rod. The first vacuum suction cup 425 is adapted to the corner of the triangular plate 66. The first clearance through hole 426 is opened at the corner of the second corner guard plate 415. The crank 418 drives the second upright plate 424 through the second slope plate 422, bringing the first vacuum suction cup 425 from the first clearance through hole 426 toward the corner of the triangular plate.
[0065] It should be noted that the first vacuum suction cup 425 is connected to the existing vacuum generator, which is mounted on the frame.
[0066] In this embodiment, the corner-cutting component 41 and the transfer component 42 work together to deliver the triangular plate generated by corner cutting to the lower end of the square tube, facilitating the welding of the triangular plate. On the other hand, the square tube can be fixed during the corner cutting process to prevent vertical movement of the square tube, ensuring the stability and accuracy of the corner cutting work and improving the corner cutting effect.
[0067] In detail, when the third hydraulic component 417 drives the lowering block 416 to descend with the two sets of first cutting units 419 to perform corner cutting, the crank rod 418 drives the second slope plate 422 to bring the first vacuum suction cup 425 through the second vertical plate 424 to approach the corner of the upper end of the square tube from the first clearance through hole 426, so that the first vacuum suction cup 425 contacts the corner of the upper end of the square tube. The first vacuum suction cup 425 sucks on the corner of the upper end of the square tube to prevent the square tube from moving up and down. After the corner cutting work is completed, the third hydraulic component 417 drives... When the moving lowering block 416 rises and resets with the two sets of first cutting units 419, the crank 418 disengages from the second slope plate 422, and the fifth elastic element 423 drives the second upright plate 424 to reset with the first vacuum suction cup 425. The first vacuum suction cup 425 then moves with the cut-off triangular plate to the gap between the second corner guard plate 415 and the side wall of the square tube. The first vacuum suction cup 425 then releases the triangular plate, which falls along the gap between the first corner guard plate 413 and the side wall of the square tube to the lower end of the square tube, ready for the welding assembly 43 to work.
[0068] Furthermore, such as Figure 10 As shown, the welding assembly 43 includes: The third feeding channel 431 is disposed on the frame 11; The material discharge box 432 is located above the third feeding channel 431 and contains several sets of pull rods 67.

The second clearance through hole 437 is opened at the corner of the first corner guard plate 413. The second welding gun 435 welds one end of the pull rod 67 to the welding hole 64 of the triangular plate 66 through the second clearance through hole 437.
[0069] In this embodiment, the welding assembly 43 enables the triangular plate to be welded to the lower end of the square tube via the pull rod 67, resulting in a high degree of automation and good welding effect.
[0070] In detail, after the triangular plate falls to the lower end of the square tube, the fourth hydraulic component drives the push rod 433 to insert into the third feeding channel 431. The second vacuum suction cup 434 at one end of the push rod 433 sucks up one end of the pull rod 67 inside the third feeding channel 431 and pushes the pull rod 67 through the through hole 65 at the lower end of the square tube and then inserts it into the welding hole 64 of the triangular plate 66. The fifth hydraulic component 436 drives the second welding gun 435 to move towards the welding hole 64 of the triangular plate 66. The second welding gun 435 welds and fixes one end of the pull rod 67 to the welding hole 64 of the triangular plate 66, thereby completing the welding work of the triangular plate.
[0071] Furthermore, such as Figures 17-19 As shown, the feeding assembly 51 includes: The first feeding channel 511 is mounted on the frame 11, and the triangular iron connector 61 is matched with the interior of the first feeding channel 511. Material box 512 is located above the first feeding channel 511, and triangular iron connectors 61 are stacked inside it. The distance from the lower end of the material box 512 to the bottom of the first feeding channel 511 is equal to the height of the triangular iron connectors 61. The movable plate 513 is slidably disposed inside the first feeding channel 511 via the first hydraulic component 514. Two sets of buffer rods 515 are slidably disposed on the movable plate 513. A first elastic component 516 is disposed between one end of the buffer rod 515 and the movable plate 513. The first push plate 517 is disposed between one end of the two sets of buffer rods 515. The first push plate 517 is provided with a stop bar 518, which contacts the lower port of the material box 512. It should be noted that the function of the baffle 518 is to prevent the triangular iron connector at the lower end of the material box 512 from falling into the first feeding channel 511 when the first push plate 517 pushes the triangular iron connector, thus ensuring that the first push plate 517 can return to its original position.
[0072] The positioning component 52 further includes: The lifting rod 524 is mounted on the moving plate 513. The first limiting rail 523 is mounted on the lower end of the lifting rod 524. The bottom of the first feeding channel 511 is provided with a clearance strip hole for the lifting rod 524 to pass through. A vertical rod 525, two sets of the vertical rods 525 are set at the bottom of the first feeding channel 511, and the lifting plate 521 is raised and lowered between the two sets of the vertical rods 525. A second elastic element 526 is provided between one end of the vertical rod 525 and the lifting plate 521. Positioning holes 527, two sets of positioning holes 527 are formed at the bottom of the first feeding channel 511, and the positioning rod 522 is matched with the positioning holes 527.
[0073] In this embodiment, by cooperating with the feeding component 51 and the positioning component 52, a single triangular iron connector can be automatically delivered to the notch of the square tube and positioned at the notch of the square tube, which facilitates the welding of the triangular iron connector.
[0074] In detail, when the support seat 131 carries the square tube to the station of the feeding assembly 51, the first hydraulic component 514 drives the moving plate 513 with the first push plate 517 to send the triangular iron connector in the first feeding channel 511 to the notch of the square tube. The first hydraulic component 514 drives the moving plate 513 to continue forward. The triangular iron connector will not move forward due to the blockage of the notch of the square tube. The moving plate 513 compresses the first elastic component 516 and continues to move forward. The moving plate 513 carries the first limiting rail 523 forward through the lifting rod 524 to the position of the lifting plate 521. The first limiting rail 523 drives the lifting plate 521 with the positioning rod 522 to rise along the positioning hole 527 and insert into the mounting hole 63 of the triangular iron connector, thereby positioning the triangular iron connector.
[0075] Furthermore, such as Figure 17 As shown, the welding assembly 53 includes a hanger 532 that is lifted and lowered on the material box 512 by a second hydraulic component 531, and two sets of first welding guns 533 symmetrically arranged on the hanger 532.
[0076] In this embodiment, the welding assembly 53 can weld the triangular iron connector to the notch at the upper end of the square tube in one go, which is highly automated and efficient.
[0077] In detail, after the positioning rod 522 positions the triangular iron connector, the second hydraulic component 531 drives the hanger 532 to descend synchronously with the two sets of first welding guns 533, so that the first welding guns 533 weld the triangular iron connector to the notch at the upper end of the square tube along the vertical edge of the notch, thus completing the assembly of the table components.
