Description

Technical Field

[0001] This invention relates to the field of positioning tooling technology, specifically a processing device for connecting parts of a lounge chair. Background Technology

[0002] In the manufacturing process of a lounge chair, the bottom support connectors are a crucial component. The processing quality of these connectors directly affects the overall structural stability, lifespan, and safety of the chair. Welding is the most important and widely used process in connector manufacturing. However, due to the diverse shapes and sizes of the connectors and the precise positioning required for welding, manual welding presents numerous challenges, such as low efficiency, inconsistent welding quality, and high labor intensity. These problems severely restrict the production efficiency and product quality of lounge chairs. The bottom support connectors that require welding assembly typically include an outer support ring, a central sleeve, and multiple sets of support bars connecting the two.

[0003] The positioning fixtures used in the welding of existing reclining chair connectors are relatively simple in function. When welding the annular component to its inner ring support bar, the annular component often needs to have a high degree of roundness. Otherwise, it is easy to encounter problems such as difficulty in assembling some support bars to the inner ring of the annular component or large welding gaps between the ends of the support bars and the inner wall of the annular component. The processing device for reclining chair connectors cannot correct the annular component, which is not conducive to improving the convenience of actual welding of reclining chair connectors and ensuring the actual support strength of the component after welding. Therefore, those skilled in the art provide a processing device for reclining chair connectors to solve the problems mentioned in the background art. Summary of the Invention

[0004] The purpose of this invention is to provide a processing device for connecting parts of a lounge chair, so as to solve the problems of difficulty in welding positioning and welding connection between components during the welding process of existing lounge chair connecting parts, and the need for repeated manual adjustment of welding positions, resulting in low efficiency and unstable quality.

Two sets of semi-gear rings that mesh with the rack are fixedly installed at the bottom of the semi-cylindrical turntable. Boosting balls are connected to the four corners of the top of the semi-cylindrical turntable by columns that are fixedly installed.

[0013] As a further description of the above technical solution: both sides of the movable frame are fixedly installed with slide rails flush with its ends, and the inside of the welding groove is provided with a slide groove that matches the slide rail. The cross-section of the slide rail and the slide groove are both T-shaped.

[0014] As a further description of the above technical solution: the rotating bracket includes a connecting cylinder rotatably mounted on the outer ring of the rotating rod. The top and bottom outer rings of the connecting cylinder are both welded with connecting plates. The outer rings of the upper and lower sets of connecting plates are integrally formed with two sets of parallel frame plates. The ends of the two sets of frame plates are provided with locking components for fixing the rotating bracket.

[0035] 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 embodiments of the present invention, and not all embodiments. Based on the 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.

[0036] Please see Figures 1 to 8 In this embodiment of the invention, a processing device for a reclining chair connector includes a welding table 10, a straightening mechanism 30, and a support base 12 used in conjunction with welding equipment. As shown in the figure, the reclining chair connector consists of an annular component 18, a sleeve 19, and four sets of support bars 110. The connector can be assembled onto a reclining chair to provide stable bottom support, etc. The annular component 18 and the support bars 110 are often made of metal square tubes. To reduce manufacturing difficulty, the annular component 18 can be formed by butt welding two sets of semi-circular metal square tubes.

[0037] The bottom of the welding table 10 of the processing device is provided with multiple sets of welding grooves 11 arranged equidistantly around its central axis. Each set of welding grooves 11 has a movable support 20 slidably installed inside. The movable support 20 is rotatably mounted with a correction mechanism 30 for positioning the annular component 18. The movable support 20 is also provided with an adjustment mechanism 40 for controlling the top of one side of the correction mechanism 30 to rotate to the inner ring of the annular component 18 to apply an outward pushing force or the top of the other side to rotate to the outer ring of the annular component 18 to apply an inward pushing force. The support base 12 is rotatably mounted with a rotating rod 13 fixedly connected to the center of the welding table 10. The outer ring of the rotating rod 13 is rotatably mounted with a rotating bracket 50 for controlling the sliding of the movable support 20 inside the welding groove 11. The top of the rotating rod 13 is provided with a limiting member 60 for positioning the sleeve 19 of the reclining chair connector.

[0038] When welding and assembling the connecting parts of the lounge chair, two sets of semi-circular metal square tubes are placed together on the top of the welding table 10 of the processing device. The operator pulls the rotating bracket 50 to rotate relative to the welding table 10. The rotating bracket 50, which rotates around the rotating rod 13, can drive four sets of moving brackets 20 to move synchronously. The moving brackets 20 drive the correction mechanism 30 connected to their top to move synchronously. Multiple correction mechanisms 30 move synchronously along the radial direction of the welding table 10, which can push the two sets of semi-circular metal square tubes to be welded to the top center position of the welding table 10. In addition, multiple correction mechanisms 30 can clamp and position the outer ring of the ring component 18, so that the workers can perform welding processing at the joint of the two sets of semi-circular metal square tubes.

[0039] The semi-circular metal square tube joint can be placed above the two welding grooves 11, which facilitates efficient welding of the three sides of the joint by the workers. After the ring component 18 is formed, the workers can snap the sleeve 19 with the outer ring support bar 110 assembled onto the limiting part 60. The end of each set of support bars 110 away from the sleeve 19 is placed above the corresponding welding groove 11. The ends of the support bars 110 abut against the inner ring of the ring component 18 to facilitate welding assembly. In the actual operation of welding and assembling the ends of multiple sets of support bars 110 with the ring component 18, the ring component 18 may be slightly deformed due to factors such as welding processing and component handling. The above deformation will affect the assembly operation of the support bars 110 and the ring component 18.

[0040] When the inner diameter of the area where the annular component 18 and one of the sets of support bars 110 meet is small, it is difficult for the support bars 110 to be fastened to the inner ring of the annular component 18 for welding assembly. The operator can rotate the adjusting mechanism 40 to drive the straightening mechanism 30 to rotate. The tops of the two sets of opposing straightening mechanisms 30 are rotated and adjusted to the inner ring of the annular component 18. Continue to rotate the adjusting mechanism 40 directly below the difficult connection point to drive the straightening mechanism 30 to rotate. Another set of straightening mechanisms 30 at the opposite position of the above-mentioned straightening mechanisms 30 can provide support for the inner side of the annular component 18. The annular component 18 continues to rotate. The annular component 18 at its contact point can be pulled outward to facilitate the normal assembly of the support bar 110 into the inner side of the annular component 18. When the inner diameter of the area where the annular component 18 and the end of one set of support bars 110 are connected is large, a large gap will be formed between the end of the support bar 110 and the inner ring of the annular component 18, affecting the normal welding of the component connection. The tops of the two sets of straightening mechanisms 30 are both abutted against the outer ring of the annular component 18. The rotating annular component 18 can push the annular component 18 at its contact point to retract inward, thereby facilitating the high-strength welding assembly between the support bar 110 and the annular component 18.

[0041] The multiple welding slots 11 provide welding space at the welding joints, preventing components from being welded onto the welding table 10 during the welding process, thus improving the convenience of actual welding processing. Furthermore, the four sets of correction mechanisms 30, each corresponding to a specific number of support bars 110, can all rotate to the inner or outer ring of the annular component 18 for support and positioning, effectively enhancing the flexibility of the processing device. After the welds on the top and sides of the joints of each component of the reclining chair connector are completed, the reclining chair connector is lifted upwards and removed from the processing device. The operator can then flip the reclining chair connector over and perform additional welding on the bottom weld at the joint. Utilizing the processing device for positioning and correction of the connectors facilitates efficient batch processing of the reclining chair connectors.

[0042] In one embodiment, see Figures 1-6 or Figure 8Specifically, the movable support 20 includes a movable frame 201 slidably mounted on the bottom of the welding tank 11. Two sets of vertical plates 202 for supporting the straightening mechanism 30 are fixedly mounted on the top of the movable frame 201. The movable frame 201 and the vertical plates 202 provide stable support for the adjusting mechanism 40 and the straightening mechanism 30. When the rotating support 50 rotates, the movable frame 201 can drive the adjusting mechanism 40 and the straightening mechanism 30 to move radially along the welding table 10. Slide rails 14, flush with both ends of the movable frame 201, are fixedly mounted on both sides of the welding tank. The interior of 11 is provided with a slide groove 15 that matches the slide rail 14. The cross sections of the slide rail 14 and the slide groove 15 can be T-shaped or I-shaped, etc. When the rotating bracket 50 pulls the moving frame 201 to move, the moving frame 201 drives the T-shaped slide rail 14 on the same side to slide inside the T-shaped slide groove 15. The slide rail 14 and the slide groove 15 can assist the moving frame 201 to make stable linear displacement. One end of the moving frame 201 and the slide rail 14 both extend directly to the outside of the welding groove 11 and the slide groove 15, which also facilitates subsequent individual disassembly of components for inspection and replacement.

[0043] Based on the above embodiments, in detail, the adjustment mechanism 40 includes two sets of parallel round rods 401 symmetrically welded inside the movable frame 201. I-beam brackets 402 are slidably mounted on the two sets of round rods 401. Two sets of racks 403 connected to the correction mechanism 30 are symmetrically provided on the top of the I-beam brackets 402. The movable frame 20 is provided with a push-pull member 404 for controlling the displacement of the I-beam brackets 402. Correspondingly, the push-pull member 404 includes a threaded rod 4041 rotatably mounted inside the movable frame 201. The threaded rod 4041 is threadedly connected to the center of the I-beam brackets 402. A turntable 4042 is fixedly mounted on one end of the threaded rod 4041 extending outside the movable frame 201. The turntable 4042 allows the operator to flexibly rotate the threaded rod 4041. The threaded rod 4041 can be rotatably connected to the movable frame 201 through a bearing component.

[0044] The correction mechanism 30 includes a semi-cylindrical turntable 301 rotatably mounted between two sets of vertical plates 202. Two sets of semi-gear rings 302 that mesh with racks 403 are fixedly mounted at the bottom of the semi-cylindrical turntable 301. At the top four corners of the semi-cylindrical turntable 301, columns 303 are fixedly mounted and connected to booster balls 304. The ends of the columns 303 can be welded to the components. Both the columns 303 and the booster balls 304 can be made of high-strength technical materials to prevent the booster balls 304 from deforming when pushing the annular component 18 to slight deformation. Small rollers or other components can also be used to replace the booster balls 304. The rolling rollers are used to abut against the surface of the annular component 18 for positioning and other operations.

[0045] The adjustment of the straightening mechanism 30 can be achieved by rotating the turntable 4042, which drives the threaded rod 4041 to rotate. The rotating threaded rod 4041 can drive the I-beam bracket 402 to slide on the two sets of round rods 401. The displaced I-beam bracket 402 drives the semi-gear ring 302 and the semi-cylindrical turntable 301 to rotate through the rack 403. The rotating semi-cylindrical turntable 301 drives the columns 303 and the booster balls 304 at its top four corners to flip. The two sets of booster balls 304 on one side can rotate to abut the outer ring of the annular component 18, and the two sets of booster balls 304 on the other side can rotate to abut the inner ring of the annular component 18. A reasonable spacing can be set between the two sets of booster balls 304 on the same side to facilitate the welding and docking of the support bar 110 with the annular component 18 between the two sets of booster balls 304 on the same side. The flexible adjustment of the straightening mechanism 30 facilitates the positioning, support and rounding of the annular component 18.

[0046] In one embodiment, see Figures 1 to 7 Specifically, the rotating bracket 50 includes a connecting cylinder 501 rotatably mounted on the outer ring of the rotating rod 13. The connecting cylinder 501 can be rotatably connected to the rotating rod 13 through a bearing component. The top and bottom outer rings of the connecting cylinder 501 are both welded with connecting plates 502. The outer rings of the upper and lower connecting plates 502 are integrally formed with two sets of parallel frame plates 503. The ends of the two sets of frame plates 503 are provided with locking parts 505 for fixing the rotating bracket 50. The bottom connecting plate 502 is connected to the bottom of each set of moving frames 201 through a hinged connecting rod 504. Correspondingly, the locking part 505 includes a positioning rod 5051 welded to the ends of the upper and lower connecting plates 502. The top of the welding table 10 is provided with a positioning groove 16 for the positioning rod 5051 to rotate. The top of the positioning rod 5051 is threadedly connected with a locking knob 5052.

[0047] When it is necessary to position the annular component 18 placed on the welding table 10, the operator rotates both sets of locking knobs 5052 away from the top surface of the welding table 10. The locking knobs 5052 pull the positioning rod 5051 to rotate inside the positioning groove 16. The positioning rod 5051 can drive the connecting plate 502 and the connecting cylinder 501 to rotate on the outer ring of the rotating rod 13 through the frame plate 503. The bottom connecting plate 502 can push and pull the moving frame 201 to move through the connecting rod 504. After the annular component 18 is positioned by the correction mechanism 30 and other components at the top of the moving frame 201, the locking knob 5052 at the top of the positioning rod 5051 is rotated. The locking knob 5052 moves down to abut the top surface of the welding table 10. The overall positioning of the rotating bracket 50 can be achieved by the friction between the components. The operation is simple and easy to learn and the positioning efficiency is also high.

[0048] In one embodiment, see Figures 1-6Specifically, the limiting component 60 includes a positioning tube 601 fixedly installed at the top of the rotating rod 13. A positioning post 602 is movably inserted from top to bottom into the center of the positioning tube 601. A baffle 603 for pressing down the top of the sleeve 19 of the reclining chair connector is welded to the top of the positioning post 602. After removing the positioning post 602 from the top of the positioning tube 601, the sleeve 19 to be assembled is fitted onto the outer ring of the positioning tube 601. Then, the positioning post 602 is snapped into the inside of the positioning tube 601, and the baffle 603 is snapped into the top of the sleeve 19, which can conveniently limit the sleeve 19. To improve the fixing effect of the sleeve 19, the positioning tube 601 and the positioning post 602 can also be threaded together. Pressing the baffle 603 to the top of the sleeve 19 can further improve the accuracy of component welding and assembly. A pull ring 17 can be welded to the top of the baffle 603 to facilitate the staff to take the baffle 603 and the positioning post 602.
