Description

Technical Field

[0001] The present invention relates to the technical field of welding, and in particular to a welding device used for manufacturing metal seats. Background Art

[0002] As living standards improve, the demand for metal furniture in public spaces is increasing, particularly for metal benches. Metal benches are gaining popularity due to their durability and modern aesthetic, particularly in public spaces like gymnasiums. Existing metal benches often feature curved seats for enhanced comfort. This design is not only aesthetically pleasing but also ergonomic, effectively distributing pressure from the seat cushion.

[0003] Because the seat frame is curved, the spacing between the welded rods needs to be consistent, and each welded rod needs to be tilted at a certain angle to ensure the overall structural stability, comfort, and aesthetics of the seat. However, existing welding equipment has difficulty maintaining consistent spacing between the welded rods during the welding process, and it is difficult to maintain a constant tilt angle for each welded rod during each weld, resulting in poor welding quality for the metal bench seat. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing device that it is difficult to keep the spacing between each welding long rod consistent during welding, and it is difficult to keep the inclination angle of each welding long rod unchanged during each welding, resulting in low welding quality of the metal bench seat, the technical problem of the present invention is: to provide a welding device for metal seat manufacturing, which can accurately rotate different welding long rods to a specified angle, and at the same time can correct and position the lateral position of the welding long rods with adjusted angles, so that the spacing between the welding long rods is consistent, thereby improving the welding quality of the metal bench seat.

[0005] A welding device for manufacturing metal seats includes a box body, two electric slide rails are provided on the box body, a slide frame is slidably connected between the two electric slide rails, two placement racks are slidably connected to the box body, two electric push rods are provided in the box body, and the two electric push rod telescopic rods are respectively connected to the two placement racks. The box body is provided with an array mechanism, an angle adjustment mechanism and a limit mechanism.

[0006] Further explanation: the sliding frame is provided with five placement slots, the placement rack is provided with a placement slot, a welded long rod is placed on the sliding frame, and a welded frame is placed on the placement rack.

[0007] Further explanation: the array mechanism includes a positioning rod, two positioning rods are slidingly connected to the sliding frame, tension springs are connected between the two positioning rods and the sliding frame, two guide tubes are provided on the box body, two winding rods are rotatably connected to the box body, and torsion springs are connected between the two winding rods and the box body, a pull rope is connected between the positioning rod and the winding rod located on the same side, and the two pull ropes pass through the two guide tubes respectively.

[0008] Further explanation: the angle adjustment mechanism includes a support rod, two support rods are slidably connected to the sliding frame, two pressure springs are connected between the two support rods, a bracket is slidably connected to the box body, two placement racks are provided with two guide frames, ten sets of limit plates are provided on the bracket, two sets of first top blocks, second top blocks and third top blocks are provided on the bracket, and two positioning blocks are provided on the box body.

[0009] Further description: sliding grooves are provided on the four guide frames, and the bracket is connected to the sliding grooves on the four guide frames in a sliding manner.

[0010] Further explanation: the limiting mechanism includes a push rod, two push rods are slidably connected to the bracket, four return springs are connected between the two push rods and the bracket, five groups of splints and two groups of guide rods are slidably connected to the two positioning blocks, the splints and the guide rods are slidably connected, several return springs are connected between the two groups of guide rods and the two positioning blocks, and extrusion rods are provided on the four guide frames, and the four extrusion rods are slidably connected to the box body.

[0011] Further description: a plurality of sliding grooves are provided on the guide rod, and the clamping plate and the sliding grooves on the guide rod are slidably connected.

[0012] Further explanation, it also includes a stabilizing mechanism. The box body is provided with a stabilizing mechanism, which includes a sliding rod. Two sliding rods are slidably connected to the two support rods. Three reset springs are connected between the sliding rods and the support rods. Four top frames are provided on the box body.

[0013] To further explain, a plurality of rollers are rotatably connected to both positioning rods.

[0014] To further explain, two or more balls are rotatably connected to the two positioning blocks.

[0015] The beneficial effects of the present invention are: 1. The support plate continues to rise, and the first top block, the second top block and the third top block will contact the five welding long rods respectively. Each welding long rod will be lifted up, and during the separation process of the welding long rod and the positioning rod, the roller will rotate to reduce the friction between the positioning rod and the welding long rod. Since the contact surface inclinations of the first top block, the second top block and the third top block and the welding long rod are different, the angle of each welding long rod will be deflected differently. In this way, different welding long rods can be accurately rotated to a specified angle, thereby improving the welding quality.

[0016] 2. After the bracket stops moving, the guide frame drives the pressure rod to continue moving, and the extrusion rod will squeeze the push rod, so that the push rod will move toward the direction close to the positioning block. The reset spring is stretched, and the push rod will hit the guide rod, so that the guide rod will extend into the positioning block. The reset spring is compressed, and the movement of the guide rod will squeeze the splint, so that the splint will extend out of the positioning block, thereby correcting and fixing the lateral position of the welding long rod with the adjusted angle. In this way, the welding position of the welding long rod can be further corrected, so that the spacing between the welding long rods is consistent, and the welding quality is further improved.

[0017] 3. After the welding frame falls onto the supporting rod, the sliding rod does not contact the welding frame. The sliding frame resets and drives the supporting rod, the sliding rod and the welded welding frame to reset together. The sliding rod will be separated from the top frame. The reset spring will reset and drive the sliding rod to reset, so that the sliding rod will contact the welding frame, thereby clamping the welding frame. In this way, the welding frame after welding is completed can move more smoothly, thereby improving the applicability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The four guide frames 94 are each provided with a slide groove, and the bracket 93 is slidably connected to the slide grooves on the four guide frames 94 .

[0043] The limiting mechanism includes a push rod 101, two push rods 101 are slidably connected to the bracket 93, four return springs 102 are connected between the two push rods 101 and the bracket 93, five groups of splints 103 and two groups of guide rods 104 are slidably connected to the two positioning blocks 99, each group of splints 103 has two splints 103, each group of guide rods 104 has two guide rods 104, the splints 103 are used to further correct the position of the welded long rod 6, the splints 103 and the guide rods 104 are slidably connected, several return springs 105 are connected between the two groups of guide rods 104 and the two positioning blocks 99, and the four guide frames 94 are provided with extrusion rods 106, and the four extrusion rods 106 are slidably connected to the box body 1.

[0044] The guide rod 104 is provided with a plurality of sliding grooves, and the clamping plate 103 is connected to the sliding grooves on the guide rod 104 in a sliding manner.

[0045] At first, the tension spring 82 is stretched and the torsion spring 85 is twisted. Subsequently, the two welding frames 7 to be welded are placed on the placement rack 4, and the five welding long rods 6 to be welded are placed in the five placement slots on the slide frame 3. Then, the user turns on the electric slide rail 2, so that the slide frame 3 slides between the two placement racks 4. During the sliding process of the slide frame 3, the tension spring 82 resets and drives the positioning rod 81 to move toward the direction close to the winding rod 84. The movement of the positioning rod 81 pushes the five welding long rods 6, so that the five welding long rods 6 are evenly spaced. The torsion reset drives the winding rod 84 to rotate. The rotation of the winding rod 84 rewinds the pull rope 86, making the pull rope 86 taut. Then, the user controls the electric push rod 5 to retract the telescopic rod. The two placing racks 4 will slide towards each other when the two placing racks 4 move. The guide frame 94 will squeeze the bracket 93 during the movement, so that the bracket 93 will move towards the direction close to the sliding frame 3. The movement of the bracket 93 will drive the limit plate 95, the first top block 96, the second top block 97 and the third top block 98 to move together. During the movement, the limit plate 95 will pass through the gap between the welding long rods 6. Each two sets of limit plates 95 will limit one welding long rod 6. The bracket continues to rise, and the first top block 96, the second top block 97 and the third top block 98 will contact the five welding long rods 6 respectively. Each welding long rod 6 will be lifted up. During the separation process of the welding long rod 6 and the positioning rod 81, the roller 12 The first top block 96, the second top block 97 and the third top block 98 are in different contact surfaces with the welding long rod 6, so that the angle of each welding long rod 6 will be deflected differently. In this way, different welding long rods 6 can be accurately rotated to a specified angle, thereby improving the welding quality. After the contact surfaces of the welding long rod 6 and the first top block 96, the second top block 97 and the third top block 98 are fitted, the bracket 93 continues to rise. After the welding long rod 6 contacts the positioning block 99, the guide frame 94 continues to move and no longer drives the bracket 93 to move. The movement of the guide frame 94 will drive the extrusion rod 106 to move in the direction close to the sliding frame 3. After the bracket 93 stops moving, the guide frame 94 drives the extrusion rod 106 to move in the direction close to the sliding frame 3. The pressure rod continues to move, and the extrusion rod 106 will squeeze the ejector rod 101, so that the ejector rod 101 will move in the direction close to the positioning block 99. The return spring 102 is stretched, and the ejector rod 101 will hit the guide rod 104, so that the guide rod 104 will extend into the positioning block 99. The return spring 2 105 is compressed, and the movement of the guide rod 104 will squeeze the clamping plate 103, so that the clamping plate 103 will extend out of the positioning block 99, thereby correcting and fixing the lateral position of the welding long rod 6 with the adjusted angle. In this way, the welding position of the welding long rod 6 can be further corrected, so that the spacing of the welding long rod 6 is consistent, and the welding quality is further improved. Then, the placement frame 4 continues to drive the guide frame 94 and the extrusion rod 106 to move, and the ejector rod 101 no longer moves. Subsequently,The placement rack 4 will contact the supporting rod 91 on the sliding frame 3, so that the supporting rod 91 will extend into the sliding frame 3, the pressure spring 92 will be compressed, and then the welding frame 7 on the placement rack 4 will contact the welding long rod 6. After the two welding frames 7 and the five welding long rods 6 are fitted together, the telescopic rod of the electric push rod 5 stops moving. At this time, the two welding frames 7 are respectively fitted with the two ends of the five welding long rods 6, and the angle adjustment of the five welding long rods 6 is completed. The welding long rod 6 as a whole maintains the same curvature as the welding frame 7. In this way, the spacing between the welding long rods 6 is evenly distributed, and the inclination angle of the welding long rod 6 is better fitted with the curvature of the welding frame 7, And improve the welding quality of the bench seat. Subsequently, the user welds the fitted welding long rod 6 and the welding frame 7. After the welding is completed, the user controls the electric push rod 5 to extend and reset the telescopic rod. The electric push rod 5 resets the telescopic rod to drive the placement rack 4 to reset. The placement rack 4 resets and drives the guide frame 94 and the extrusion rod 106 to reset. The placement rack 4 resets and disengages the support rod 91. The pressure spring 92 resets and drives the support rod 91 to reset, so that the support rod 91 will move to the bottom of the welding frame 7. The pressure rod resets and the push rod 101 disengages. The reset spring 102 resets and drives the push rod 101 to reset. The push rod 101 resets and disengages the guide rod 104. The reset spring 2 105 resets Drive guide rod 104 to reset, guide rod 104 reset drives clamping plate 103 to reset, clamping plate 103 resets and disengages from welding long rod 6, guide frame 94 continues to reset and move to drive bracket 93 to reset, bracket 93 reset drives limit plate 95, first top block 96, second top block 97 and third top block 98 to reset, limit plate 95, first top block 96, second top block 97 and third top block 98 reset and drive the welded welding long rod 6 and welding frame 7 to fall, welding frame 7 will fall on support rod 91, the placement groove on support rod 91 will limit welding frame 7 to prevent welding frame 7 from tilting, then limit plate 95, first top block 96, second top block 9 7 and the third top will be separated from the welding long rod 6. After the bracket 93 is reset, the electric push rod 5 telescopic rod stops moving, and then the sliding frame 3 is reset. The reset of the sliding frame 3 will drive the positioning rod 81 and the supporting rod 91 to reset. During the reset process of the positioning rod 81, the pull rope 86 is pulled by the positioning rod 81, the winding rod 84 will unwind and stretch, and the torsion spring 85 will be twisted. After the stretching and unwinding are completed, the positioning rod 81 continues to reset and moves away from the tension spring 82. The tension spring 82 is stretched. After the sliding frame 3 is reset, the positioning rod 81 is reset. Then, the user removes the welded long rod 6 and welding frame 7, thereby completing a welding job.

[0046] Example 2: Based on Example 1, Figures 9-18As shown, a stabilizing mechanism is also included. The box body 1 is provided with a stabilizing mechanism, which is used to further stabilize the welded workpiece. The stabilizing mechanism includes a sliding rod 111, which is used to limit the welding frame 7. Two sliding rods 111 are slidably connected to the two support rods 91. A reset spring three 112 is connected between the sliding rods 111 and the support rods 91. Four top frames 113 are provided on the box body 1.

[0047] A plurality of rollers 12 are rotatably connected to the two positioning rods 81 . The rollers 12 are used to reduce the friction between the welding rod 6 and the positioning rods 81 .

[0048] Two or more balls 13 are rotatably connected to the two positioning blocks 99 , and the balls 13 are used to reduce the friction between the welding long rod 6 and the positioning blocks 99 .

[0049] When the sliding frame 3 is moved to the position between the two placement racks 4, the sliding frame 3 will drive the sliding rod 111 to move together. During the movement of the sliding rod 111, it will contact the top frame 113, and the top frame 113 will squeeze the sliding rod 111, so that the sliding rod 111 will move in the direction close to the sliding frame 3, and the return spring 3 112 will be stretched. After the sliding frame 3 drives the welding long rod 6 to move to the welding position, the sliding rod 111 no longer moves.
