Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and specifically to an assembly and welding device for the design of wrought iron beds. Background Technology

[0002] A bed is a type of furniture. Bed styles include Western-style box beds, traditional Chinese canopy beds, and simple canopy beds. They are also categorized by material: iron beds, wooden beds, stainless steel beds, fabric beds, and leather beds. A bed generally consists of a headboard, bed frame, and footboard. In the production of iron beds, the headboard, bed frame, and footboard are welded together sequentially, and then bolted together. This method of construction has the following drawbacks in actual use:

[0003] 1. During the production and processing of wrought iron beds, the headboard, bed board and footboard are welded in sequence, which increases the time required for the welding process and thus reduces the processing efficiency of wrought iron beds.

[0004] 2. After welding the headboard, bed board, and footboard, the headboard, bed board, and footboard are manually supported and positioned. They are then fixed to the bed board with bolts before inspection, which is quite troublesome.

[0005] Therefore, this application proposes an assembly and welding device for wrought iron bed design. Summary of the Invention

[0051] The positioning mechanism 4 includes a positioning frame 41 fixedly mounted on a mounting plate 35. A positioning component 411 for positioning the headboard 21 is mounted on the positioning frame 41. A positioning frame 43 is mounted on the positioning frame 41 via a rotary connection mechanism 42. A positioning component 431 for positioning the bed board 23 is mounted on the positioning frame 43. A positioning frame 45 is mounted on the positioning frame 43 via a rotary connection mechanism 44. A positioning component 451 for positioning the footboard 22 is mounted on the positioning frame 45. The rotary connection mechanisms 42 and 44 allow the positioning frames 41, 43, and 45 to have three states:

[0052] First state: Positioning frame 1 41, positioning frame 2 43 and positioning frame 3 45 form an L-shape;

[0053] Second state: Positioning frame 1 41, positioning frame 2 43 and positioning frame 3 45 are located on the same vertical plane;

[0054] Third state: Positioning frame 1 41, positioning frame 2 43 and positioning frame 3 45 form an H shape;

[0055] A movable plate 3 5 is vertically slidably mounted on the upright plate 11 above the unloading platform 13 via an electric slider 2 15. Horizontally fixed telescopic rods 3 51 are symmetrically fixed on the movable plate 3 5. Connecting blocks 52 are fixed to the telescopic ends of the two telescopic rods 3 51. A hydraulic cylinder 3 53 connected to the connecting block 52 is fixedly mounted on the movable plate 3 5. An installation frame 54 is hinged to the connecting block 52 and located below it. A motor 1 59 for driving the installation frame 54 to rotate is fixedly mounted on the connecting block 52. Movable blocks 55 are symmetrically slidably mounted on the installation frame 54. A welding gun 56 is fixedly mounted on the movable block 55. An electric slider 3 57 for driving the movable block 55 to slide is fixedly mounted on the installation frame 54.

[0056] During the machining of the iron bed, when welding the headstock 21, tailstock 22, and bed board 23, the positioning frames 41, 43, and 45 are formed in an L-shape by rotating connection mechanism 1 42 and rotating connection mechanism 2 44. Through the cooperation of electric slider 1 14, hydraulic cylinder 33, and hydraulic cylinder 36, the mounting plate 35 is brought close to the loading table 12, and the frame 211, crossbar 212, and vertical bar 213 are loaded onto the positioning frame 41. The positioning assembly 411 positions the frame 211, crossbar 212, and vertical bar 213, and the frame 221, crossbar 222, and vertical bar 223 are loaded onto the positioning frame 45, thus assembling the frame... The second body 221 and the first frame 211 are symmetrically arranged. The second frame 221, the second horizontal bar 222, and the second vertical bar 223 are positioned by the third positioning component 451. The bed frame 231, the bottom support rod 232, and the top support rod 233 are then loaded onto the second positioning frame 43. The second positioning component 431 further positions the bed frame 231, the bottom support rod 232, and the top support rod 233, facilitating the loading operation. At this time, the electric slider 14, the hydraulic cylinder 1 33, and the hydraulic cylinder 2 36 work together to move the second positioning frame 43 away from the loading platform 12. The rotating connecting mechanism 1 42 and the rotating connecting mechanism 2 44 work together to connect the first positioning frame 41, the second positioning frame 43, and the third positioning frame 45. Located on the same vertical plane, the positioning frame 41 is brought closer to the moving plate 5 by the cooperation of electric slider 14, hydraulic cylinder 33, and hydraulic cylinder 36. Then, the two welding torches 56 are brought closer to the area to be welded by the cooperation of hydraulic cylinder 53, two electric sliders 57, and motor 59. Welding can then be performed using the two welding torches 56. With the cooperation of electric slider 15, the moving plate 5 slides downwards on the vertical plate 11, allowing welding of the headboard 21, tailboard 22, and bed board 23 from top to bottom. This facilitates welding of the headboard 21, tailboard 22, and bed board 23. After welding, the moving plate 3 is moved away from the moving plate 5 by electric slider 14, and then rotated... The cooperation of connecting mechanism 1 42 and rotating connecting mechanism 2 44 forms an H-shape between positioning frame 1 41, positioning frame 2 43 and positioning frame 3 45, which can achieve the pre-positioning effect of bed body 2. This facilitates the assembly of bolts between bed board 23 and headboard 21 and tailboard 22, eliminating the need for manual support and positioning of the welded headboard 21, tailboard 22 and bed board 23, which is more convenient and improves the processing efficiency of wrought iron beds. After the bolts between bed board 23 and headboard 21 and tailboard 22 are assembled, the assembled bed body 2 can be placed on unloading table 13 for unloading by the cooperation of electric slider 14, hydraulic cylinder 1 33 and hydraulic cylinder 2 36.

[0057] In this embodiment, the longitudinal section of the positioning frame 41 is U-shaped. The positioning component 411 includes a connecting rod 4111 slidably mounted between the inner walls of both sides of the positioning frame 41. An electric slider 4112 for driving the connecting rod 4111 to slide is fixedly mounted on the positioning frame 41. Pneumatic grippers 4113 are symmetrically fixed on both the connecting rod 4111 and the positioning frame 41, near the side of the moving plate 5. A clamping component 4114 is installed on the positioning frame 41, between its inner top wall and the side opposite to the connecting rod 4111. In use, the welding headstock 2 is... At time 1, the pneumatic gripper 4113 on the positioning frame 41 clamps and positions the processed frame 211. According to the distance between the crossbar 212 and the frame 211, the electric slider 4112 causes the connecting rod 4111 to slide on the positioning frame 41. The pneumatic gripper 4113 on the connecting rod 4111 clamps and positions the crossbar 212. Then, the clamping assembly 4114 clamps and positions multiple vertical bars 213. The loading of the frame 211, crossbar 212 and vertical bars 213 can be completed, and the headstock 21 can be welded.

[0058] The longitudinal section of the second positioning frame 43 is rectangular. The second positioning component 431 includes pneumatic grippers 4311 and clamping components 4312.

Electric push rods 4316 are symmetrically fixed on the side of the connecting plate 4314 near the second positioning frame 43. The clamping components 4312 are fixedly connected to the piston rods of the two electric push rods 4316. When welding the bed plate 23, the machining is performed by the four pneumatic grippers 4311 on the second positioning frame 43. The bed frame 231 is clamped and positioned, and then multiple bottom support rods 232 are clamped and positioned by clamping component 2 4312. After welding the multiple bottom support rods 232 to the bed frame 231 by two welding guns 56, the positioning of the multiple bottom support rods 232 by clamping component 2 4312 is canceled. The clamping component 2 4312 is moved away from the bottom support rods 232 by two electric push rods 1 4316. The connecting plate 4314 is rotated 90 degrees on the fixed frame 4313 by motor 2 4315. The clamping component 2 4312 is moved closer to the bottom support rods 232 by two electric push rods 1 4316. Then, multiple top support rods 233 are clamped and positioned by clamping component 2 4312. Thus, the multiple top support rods 233 can be welded to the bed frame 231 by two welding guns 56, thereby completing the welding of the bed board 23.

[0059] The positioning frame 3 45 is symmetrically arranged with the positioning frame 1 41, and the positioning component 3 451 has the same structure as the positioning component 1 411. By setting the positioning frame 3 45 and the positioning frame 1 41 to be symmetrically arranged, and the positioning component 3 451 has the same structure as the positioning component 1 411, when welding the tailstock 22, when loading the frame 221, the frame 221 and the frame 1 211 are placed symmetrically. Similarly, the frame 221, the horizontal bar 222 and the vertical bar 223 are clamped and positioned by the positioning component 3 451, and then the frame 221, the horizontal bar 222 and the vertical bar 223 can be welded by the two welding guns 56.

[0060] In this embodiment, the clamping assembly 4114 includes a mounting bracket 41141 fixedly mounted on the positioning frame 41.

A pneumatic gripper 41144 is fixedly mounted on the side of the mounting seat 41143 closest to the moving plate 5. A hinge rod 41145 is hinged to the side of the mounting seat 41143 away from the moving plate 5. Two adjacent hinge rods 41145 are hinged together. A horizontally oriented bidirectional threaded rod 41146 is rotatably mounted on the mounting bracket 41141, and the bidirectional threaded rod 41146 is threadedly connected to two mutually distant mounting seats 41143. 1. A motor 41147 is fixedly installed on the mounting frame 41141 to drive the bidirectional threaded rod 41146 to rotate. In use, when the distance between two adjacent mounting seats 41143 needs to be adjusted according to the welding of the wrought iron bed, the motor 41147 causes the bidirectional threaded rod 41146 to rotate on the mounting frame 41141, so that the two mounting seats 41143 that are far apart move closer or further apart. Multiple hinge rods 41145 rotate on multiple mounting seats 41143 respectively. The rotation between two adjacent hinge rods 41145 causes multiple mounting seats 41143 to slide on two slide rods 41142, so that the distance between multiple mounting seats 41143 is equal, thereby making the distance between two adjacent pneumatic grippers 41144 equal.

[0061] Example 2

[0062] like Figures 1-12 As shown, based on the above embodiments, this embodiment further provides the following:

[0063] In this embodiment, the rotating connection mechanism 42 includes a rotating plate 421, a telescopic rod 422, a movable plate 423, an electric push rod 424, a motor 425, and an electric slider 426.

[0064] A rotating plate 421 is rotatably mounted on one side of the positioning frame 41. A motor 425 for driving the rotating plate 421 to rotate is fixedly mounted on the positioning frame 41. Telescopic rods 422 are symmetrically fixed on the side of the rotating plate 421 near the positioning frame 43. Movable plates 423 are fixed to the telescopic ends of the two telescopic rods 422. The movable plates 423 are slidably connected to the positioning frame 43. Specifically, the sliding direction between the sliding plates 423 and the positioning frame 43 is perpendicular to the axial direction of the telescopic rods 422. An electric slider 426 connected to the movable plate 423 is fixedly mounted on the positioning frame 43. An electric push rod 424 connected to the movable plate 423 is fixedly mounted on the rotating plate 421. In use, the electric push rod 424 causes the movable plate 423 to move closer to or away from the positioning frame 41 along the two telescopic rods 422. Motor 425 rotates the rotating plate 421 on the positioning frame 41, which in turn causes the movable plate 423 to rotate around the rotating plate 421 via two telescopic rods 422. This causes the positioning frame 43 to rotate around the rotating plate 421, making the positioning frame 43 perpendicular to the positioning frame 41. This makes the bed frame 231 perpendicular to the frame 211. With the help of electric push rod 424, the bed frame 231 can be brought into contact with the frame 211. Similarly, the rotating connecting mechanism 44 makes the positioning frame 45 perpendicular to the positioning frame 43, making the frame 221 perpendicular to the bed frame 231. By setting the movable plate 423 to slide on the positioning frame 43, when the positioning frame 43 is perpendicular to the positioning frame 41, the electric slider 426 allows the movable plate 423 to slide on the positioning frame 43, thus adjusting the height of the positioning frame 43 and consequently the height of the bed frame 231, increasing the applicability of the equipment.

[0065] In this embodiment, a support plate 58 is fixedly installed on the top of the movable plate 5. Vertical telescopic rods 581 are symmetrically fixed on the support plate 58. Suction hoods 582 are fixed to the bottom of the two telescopic rods 581. A hydraulic cylinder 583 connected to the suction hood 582 is fixed on the support plate 58. A negative pressure filter mechanism 6 is installed on the suction hood 582, which is used to extract and filter the air inside the suction hood 582. A ventilation component 7, which can communicate with the opening of the suction hood 582, is installed on the mounting frame 54. By setting the negative pressure filter mechanism 6 and the ventilation component 7, the hydraulic pressure is controlled when the two welding torches 56 are performing welding operations. When cylinder 4 583 operates, the suction hood 582 slides along the two telescopic rods 581, causing the suction hood 582 to move synchronously with the mounting frame 54. During this process, the negative pressure filtration mechanism 6 is activated, drawing air out of the suction hood 582. This allows air from the mounting frame 54 to enter the suction hood 582 through the ventilation assembly 7. As a result, the fumes generated during welding of the two welding torches 56 are drawn into the suction hood 582 through the ventilation assembly 7. The negative pressure filtration mechanism 6 then filters the fumes before discharging them, achieving a filtration effect during welding of the two welding torches 56, improving ambient air quality, and thus benefiting the health of the workers.

[0066] In this embodiment, the negative pressure filtration mechanism 6 includes:

[0067] The exhaust fan 61 and the suction hood 582 have mounting holes communicating with each other. The exhaust fan 61 is fixedly installed in the mounting holes. The suction hood 582 has a mounting shell 62 communicating with the mounting holes. The top of the mounting shell 62 has a slot. A filter plate 63 is inserted into the mounting shell 62 and located in the slot to seal the inside of the mounting shell 62. In use, controlling the exhaust fan 61 will draw the air in the suction hood 582 out through the mounting holes and then discharge it out through the mounting shell 62. The air flows inside the mounting shell 62. During operation, the air can be filtered by the filter plate 63 before being discharged, thus achieving the effect of filtering the air drawn out from the intake hood 582. A sealing plate 64 for sealing the slot opening is hinged on the mounting shell 62. The sealing plate 64 is fixed to the mounting shell 62 by a buckle. When in use, the buckle is removed to fix the sealing plate 64 to the mounting shell 62, and the sealing plate 64 can be rotated to remove the seal on the slot opening, so that the filter plate 63 can be disassembled and replaced, which is convenient for disassembling and replacing the filter plate 63.

[0068] Example 3

[0069] like Figures 1-12 As shown, based on the above embodiments, this embodiment further provides the following:

[0070] In this embodiment, the ventilation assembly 7 includes a ventilation shell 71 fixedly installed on the side of the mounting frame 54 near the suction hood 582. A second ventilation shell 72 that can communicate with the suction hood 582 is installed on the side of the first ventilation shell 71 near the suction hood 582. In use, the second ventilation shell 72 is connected to the opening end of the suction hood 582, and the exhaust fan 61 is working. When the air in the suction hood 582 is drawn out through the mounting hole, the air at the mounting frame 54 can be drawn into the suction hood 582 through the first ventilation shell 71 and the second ventilation shell 72.

[0071] In this embodiment, the second vent housing 72 includes two symmetrically arranged housings 721, each movably sleeved on the outer side of the end of the first vent housing 71. Horizontally fixed horizontal telescopic rods 73 are symmetrically fixed on both sides of the first vent housing 71. Contact plates 74 are fixed to the telescopic ends of the two telescopic rods 73. An electric actuator 75 connected to the contact plate 74 is fixedly installed on the first vent housing 71. Guide posts 76, movably penetrating the contact plate 74, are symmetrically fixed on both sides of the first vent housing 71 on the two housings 721. A spring 77, sleeved outside the guide post 76, is installed between the contact plate 74 and the opposite side of the housing 721. A pressure sensor 78 is fixedly installed on the side of the housing 721 near the contact plate 74, between the opposite sides of the two guide posts 76. Sensor 78 is connected to an external PLC control system. A receiving groove 722 is provided on the side of housing 721 near the suction hood 582. An airbag 79 is fixedly installed on housing 721 and in the receiving groove 722. It is worth noting that the airbag 79 is connected to an external air pump. When the two welding guns 56 are welding, the hydraulic cylinder 4 583 is operated to make the suction hood 582 slide along the two telescopic rods 581, so that the suction hood 582 and the two housings 721 are on the same horizontal plane. Gas is delivered to the two airbags 79 through the two air pumps, so that the two airbags 79 are in contact with the suction hood 582, thereby increasing the fit between the suction hood 582 and the two housings 721 and increasing the sealing between the suction hood 582 and the two housings 721.After welding the headboard 21, footboard 22, and bed board 23, the electric slider 14 moves the moving plate 3 away from the moving plate 5. Through the cooperation of the rotating connecting mechanism 1 42 and the rotating connecting mechanism 2 44, the positioning frames 1 41, 2 43, and 3 45 form an H-shape, thus pre-positioning the bed body 2. After assembling the bed board 23 with the headboard 21 and footboard 22 using bolts, the hydraulic cylinder 4 583 is operated to move the suction hood 582 along the two telescopic rods 581 to above the mounting frame 54. At this time, the motor 1 59 is controlled to rotate the mounting frame 54 on the connecting block 52, making the mounting frame 54 horizontal. Then, the hydraulic cylinder 4 583 is operated to... The air hood 582 moves downward along the two telescopic rods 581. Through the cooperation of the electric slider 14, hydraulic cylinder 33, and hydraulic cylinder 36, the air hood 582 comes into contact with the side of the bed end frame 22 away from the bed board 23. Then, through the two electric push rods 75, the two housings 721 move downward. With the cooperation of the hydraulic cylinder 53, the two housings 721 come into contact with the side of the bed end frame 22 closest to the bed board 23, thus achieving pre-positioning of the bed frame. At this point, the positioning components 411, 431, and 451 can be removed from positioning the bed body 2. Then, through the rotating connection mechanisms 42 and 44, the positioning frames 41, 43, and 451 are positioned... The components 5 form an L-shape. Through the cooperation of electric slider 14, hydraulic cylinder 33, and hydraulic cylinder 36, positioning frame 45 can be moved to the side of bed 2 near the loading platform 12. Then, through the cooperation of electric slider 15 and hydraulic cylinder 583, bed 2 can be placed on unloading platform 13. After bed 2 is placed, hydraulic cylinder 53 moves the two housings 721 to the middle position above bed board 23. At this time, two air pumps supply gas to the two airbags 79, causing the airbags 79 to expand and extend outside the housings 721. Then, two electric push rods 75 sequentially slide the two housings 721 back and forth along the two telescopic rods 73, causing the two airbags 79 to sequentially apply flexible pressure to both sides of the top of bed board 23. The guide posts 76 on both housings 721 slide between the contact plate 74. The spring 77 outside the guide post 76 deforms under force, and the pressure sensor 78 on the housing 721 detects a change in force and transmits it to the external PLC control system. The external PLC control system counts the number of times the two airbags 79 press against the top two sides of the bed board 23 in sequence, thus simulating the number of times a user rolls while lying on the bed 2. By observing whether there is any loosening or detachment at the assembly points of the headboard 21, footboard 22 and bed board 23, as well as at the welded joints of the headboard 21, footboard 22 and bed board 23, the overall stability of the bed 2 can be tested.In addition, after the bed frame 2 is placed, two air pumps can be controlled to hide the two airbags 79 into the two receiving slots 722 respectively. At this time, the two electric push rods 75 cause the two housings 721 to slide downwards along the two telescopic rods 73 to press down on the bed board 23, thus applying downward pressure to the bed board 23. The guide posts 76 on the two housings 721 slide between the contact plates 74. The springs 77 outside the guide posts 76 deform under force, and the pressure sensor 78 on the housings 721 changes the force detection signal, which is transmitted to the external PLC control system. The operator can perform load-bearing test on the bed frame 2 by observing whether there is any loosening or detachment at the assembly points of the headboard 21, tailboard 22, and bed board 23, as well as at the welded joints of the headboard 21, tailboard 22, and bed board 23.

[0072] In this embodiment, two sliding blocks 8 are horizontally slidably installed on the inner wall of the suction hood 582 on the side away from its opening end. A fixing rod 81 is fixedly installed on the side of the sliding block 8 near the opening end of the suction hood 582. A sleeve rod 82 is movably sleeved on the outer end of the fixing rod 81 away from the sliding block 8. A spring 83 connected to the inner wall of the sleeve rod 82 is fixedly installed on the outer end of the fixing rod 81 away from the sliding block 8. A horizontally oriented bidirectional threaded rod 84 is rotatably installed inside the suction hood 582. The second 84 is threadedly connected to both sliding blocks 8. A motor 585, connected to the bidirectional threaded rod 84, is fixedly installed inside the suction hood 582. When the tailstock 22 is clamped by the sleeve rod 82 via the vent housing 72 and the suction hood 582, the suction hood 582 slides along the two telescopic rods 581 via the hydraulic cylinder 4 583. With the cooperation of the motor 5 85, the bidirectional threaded rod 84 rotates, causing the two sliding blocks 8 to slide in opposite directions within the suction hood 582, allowing both sleeve rods 82 to... The vent housing 72 is inserted between the opposite sides of the frame 221 and the crossbar 222 and is attached to the inner top wall of the frame 221. At this time, through the cooperation of the electric slider 215, the hydraulic cylinder 3 53 and the motor 1 59, the vent housing 72 is attached to the frame 221, clamping the end frame 22. The two sleeve rods 82 support the frame 221, thereby improving the positioning effect of the end frame 22. During this process, when the vent housing 72 contacts the ends of the two sleeve rods 82, the two sleeve rods 82 move along the two fixed rods 81 respectively. Sliding into the suction hood 582, the springs 83 at the ends of the two fixed rods 81 are deformed under force, which does not affect the ventilation shell 72 from moving closer to the frame 221 and fitting into the frame 221. When inspecting the bed 2, the suction hood 582 is slid along the two telescopic rods 581 by the hydraulic cylinder 583, so that the two sleeve rods 82 abut against the crossbar 222, thereby achieving the positioning effect of the bed tail frame 22, which is beneficial for the inspection of the bed 2.

[0073] In this embodiment, a fixed plate 9 is fixedly installed on the side of the movable plate 3 away from the movable plate 5. An exhaust hood 92 is vertically slidable on the fixed plate 9 via an electric slider 6 91. The exhaust hood 92 is connected to an external inert gas delivery pump. Through the design of the fixed plate 9, the electric slider 6 91, and the exhaust hood 92, when the two welding torches 56 are welding, the electric slider 6 91 causes the exhaust hood 92 to slide synchronously on the fixed plate 9 and the mounting frame 54, thereby ensuring the exhaust hood 92 is properly positioned. For the vent housing 71, an external inert gas delivery pump is controlled to deliver inert gas to the vent hood 92. The exhaust fan 61 operates, causing air at the mounting frame 54 to be drawn through vent housing 71 and vent housing 72 into the suction hood 582, simultaneously drawing inert gas into the suction hood 582, thereby improving safety. A perforation 93 is provided at the bottom of the fixing plate 9, and a receiving plate 94 is horizontally inserted through the perforation 93 on the fixing plate 9. One end of the receiving plate 94 can extend... Below the movable plate 3 5, an electric actuator 4 95 connected to the receiving plate 94 is fixedly installed on the fixed plate 9. A collection box 16 with an open top is placed on top of the base 1 and below the fixed plate 9. During use, when welding the wrought iron bed, the receiving plate 94 is located below the two welding torches 56. When the two welding torches 56 are welding, the weld ash produced falls onto the receiving plate 94 under their own gravity. After welding the wrought iron bed is completed, it is connected by rotation. When mechanism 1 42 and rotary connection mechanism 2 44 pre-position the headstock 21, tailstock 22 and bed board 23, the fixing plate 9 is located above the collection box 16. The electric actuator 4 95 is controlled to make the receiving plate 94 slide in the through hole 93. The fixing plate 9 can scrape the top of the receiving plate 94, thereby scraping and cleaning the welding ash that falls to the top of the receiving plate 94, so that the welding ash falls into the collection box 16. The welding ash is collected by the collection box 16, which facilitates the treatment of the welding ash.
