Description

Technical Field

[0001] The invention relates to the technical field of welding technology, in particular to a hanging basket drip trough welding device. Background Art

[0002] The hanging basket drip trough is traditionally welded on the panel. The drip trough is made by folding the steel plate in half and cutting the round tube. The length of the drip trough made by cutting the round tube should not be too long. If the drip trough is too long, it needs to be extended, and the production process is too complicated.

[0003] Chinese patent CN107414262B discloses a welding process for a hanging basket drip trough, including welding of a round tube and a hanging basket, pre-drilling of slots on the hanging basket frame before welding, surface treatment of the frame to be welded, cleaning of dirt on the surface of the frame to be welded, checking whether the surface of the frame to be welded is damp, and welding after drying, using nitrogen shielded welding, using H08Mn2SiA steel welding wire, welding the slots and the contact part between the panel and the round tube, performing post-weld treatment after welding, cleaning of welding slag and spatter, grinding of unsightly welds, and coating of an anti-rust layer on the grounded welding track.

[0004] However, when welding the joint between the panel and the round tube by this method, the hanging basket frame, the panel and the round tube need to be fixed separately, which is relatively cumbersome.

[0035] When the welding device in the present application is in use, the staff places the drip trough to be welded on the placing table 1, and keeps the circular tube axis of the drip trough to be welded parallel to the axis of the positioning tube 241 on the movable seat 2. The two movable seats 2 on the placing table 1 move horizontally, so that the first rectangular frame 21 approaches the two sides of the drip trough to be welded, until the movable baffles 22 on the two first rectangular frames 21 fit with the two sides of the drip trough to be welded, thereby clamping and fixing the drip trough to be welded. The movable baffles 22 in this embodiment can be adjusted to a suitable position according to the size and size of the drip trough to be welded, so that it can accurately fit the drip trough to be welded, and also release the side space of the drip trough to be welded so that the two ends of the circular tube are not blocked. Before the movable baffles 22 clamp and fix the drip trough to be welded, the staff can move the second rectangular frame 23 and the sliding plate 24 on the first rectangular frame 21, so that the positioning tube 241 on the sliding plate 24 is inserted into one end of the circular tube, and the second rectangular frame 23 can move vertically on the first rectangular frame 21, and the sliding plate 24 in the second rectangular frame The positioning tube 241 is arranged at one end of the positioning tube 241 and a plurality of top posts 242 are arranged at one end of the positioning tube 241 and the top posts 242 are arranged at the radial direction of the positioning tube 241 and the positioning tube 241 is arranged at the radial direction of the positioning tube 241 and the top posts 242 are arranged at the radial direction of the positioning tube 241 and the positioning tube 241 is arranged at the radial direction of the positioning tube 241 and the positioning tube 241 is adjusted to the axial position of the circular tube and the circular tube is stabilized on the inner wall of the circular tube to prevent the circular tube from rotating around its own axis due to external force. The position of the joint between the circular tube and the panel is stable during welding and the welding effect is ensured. After the drip trough and the circular tube to be welded are fixed, the welding head 3 on the placing table 1 can be moved along the joint between the circular tube and the panel and welding is performed. The welding head 3 is installed on the sliding seat 13 and the sliding seat 13 is slidably installed on the sliding bracket 12 on the top bracket 11. The movement of the sliding seat 13 and the sliding bracket 12 can realize the movement of the welding head 3 in the horizontal direction. The welding head 3 can be the existing technology and will not be described in detail here.

[0036] In order to solve the problem of how to achieve synchronous radial movement of the top column 242 in the positioning cylinder 241 along the positioning cylinder 241, the following features are specifically provided:

[0037] A plurality of guide holes 243 are provided on the positioning cylinder 241. The guide holes 243 extend radially along the positioning cylinder 241. The diameter of the guide holes 243 is the same as the diameter of the top column 242. The top column 242 is inserted into the guide holes 243. The upper and lower ends of the top column 242 are round heads. A conical top rod 244 is coaxially installed in the positioning cylinder 241. The conical top rod 244 has a gradually decreasing taper toward one end of the top column 242. One end of the top column 242 located inside the positioning cylinder 241 fits into the conical top rod 244. The conical top rod 244 moves along the axis of the positioning cylinder 241 to push the top column 242 to move along the axis of the guide hole 243.

[0038] The top column 242 in the positioning cylinder 241 in this embodiment is inserted in the guide hole 243 to ensure that the top column 242 can only move along the axial direction of the guide hole 243. The upper and lower ends of the top column 242 are round heads, so when one end of the top column 242 is in contact with the inner wall of the circular tube, effective contact can be guaranteed. A conical top rod 244 is coaxially arranged in the positioning cylinder 241. When the conical top rod 244 moves toward the top column 242, the round head end of the top column 242 can be in contact with the conical surface of the conical top rod 244, so that the top column 242 moves toward the inner wall of the circular tube with the movement of the conical top rod 244, and the movement of each top column 242 is synchronized. The pressure exerted by the conical top rod 244 on the top column 242 ensures that the circular tube will not rotate easily. After welding is completed, the conical top rod 244 moves in the opposite direction to release the support of the top column 242 on the circular tube, which is convenient for unloading the drip trough to be welded.

[0039] In order to achieve the purpose of first driving the moving seat 2 to move and clamp the drip groove to be welded by a single power source, and then driving the top column 242 in the positioning cylinder 241 to fit with the inner wall of the round tube, the following features are specifically set:

[0040] The end of the positioning cylinder 241 away from the top column 242 is coaxially provided with an air passage 245, and the end of the conical top rod 244 away from the top column 242 is coaxially provided with a first piston rod 246, which is inserted into the air passage 245; the moving seat 2 is provided with a second piston rod 25 (such as Figure 6 As shown), a piston cylinder 14 coaxially arranged with the second piston rod 25 is fixedly installed on the placement table 1, and the second piston rod 25 is inserted in the piston cylinder 14, and the end of the piston cylinder 14 away from the second piston rod 25 is connected to the first air inlet pipe 141, and the other end of the first air inlet pipe 141 is connected to the outlet end of the air source 142 fixedly installed on one side of the placement table 1; a pressure relief valve 143 is provided on the upper side of one end of the piston cylinder 14 close to the first air inlet pipe 141, and the outlet end of the pressure relief valve 143 is connected to the second air inlet pipe 144, and the outlet end of the second air inlet pipe 144 is connected to the air duct 245 of the positioning cylinder 241.

[0041] The placement table 1 in this embodiment is provided with a piston cylinder 14 and an air source 142 on one side. The air source 142 can be any existing technology. The air source 142 delivers gas to the piston cylinder 14 through the first air inlet pipe 141, so that the air pressure in the piston cylinder 14 increases. The increase in the air pressure in the piston cylinder 14 will push the second piston rod 25 inserted in the piston cylinder 14 on the moving seat 2 to move along the axis of the piston cylinder 14, so that the moving seat 2 approaches the center position of the placement table 1 until the moving baffle 22 on the moving seat 2 fits with the drip groove to be welded, and the moving seat 2 stops moving. The gas delivered by the air source 142 to the piston cylinder 14 causes the air pressure in the piston cylinder 14 to continue to increase until it exceeds the pressure range of the pressure relief valve 143. The pressure relief valve 143 opens to relieve the pressure in the piston cylinder 14, and the air source 1 The gas transported by 42 to the piston cylinder 14 enters the air channel 245 at one end of the positioning cylinder 241 through the second air inlet pipe 144 at the output end of the pressure relief valve 143, and moves the conical push rod 244 to move the first piston rod 246 inserted in the air channel 245, so as to realize the movement of the conical push rod 244 toward one end of the push column 242, and drive the push column 242 to move radially along the positioning cylinder 241 combined with the inner wall of the circular tube. The air source 142 is the only power source to save production costs. The presence of the pressure relief valve 143 can ensure that there is sufficient air pressure in the piston cylinder 14 to keep the moving baffle 22 of the moving seat 2 clamped and fixed to the welding drip groove. Gas nozzles can be set on the first air inlet pipe 141 and the second air inlet pipe 144 to facilitate the discharge of gas in the piston cylinder 14 and the air channel 245 when the moving seat 2 is reset.

[0042] In order to ensure the stability of the moving path of the moving seat 2, the following features are specifically set:

[0043] A plurality of limiting slide grooves 15 are arranged on the upper surface of the placing table 1, and the limiting slide grooves 15 extend in a horizontal direction perpendicular to the length direction of the moving seat 2. The bottom of the moving seat 2 is provided with limiting blocks 26 with the same number as the limiting slide grooves 15, and the limiting blocks 26 are inserted in the limiting slide grooves 15 for movement.

[0044] The bottom of the movable seat 2 in this embodiment is provided with a plurality of limit blocks 26, which are inserted into the limit slide grooves 15 provided on the upper surface of the placement table 1 to limit the moving path of the movable seat 2, thereby ensuring that the movable seat 2 can only move in the horizontal direction. Moreover, the existence of the limit slide grooves 15 ensures that there are no protrusions on the upper surface of the placement table 1, thereby ensuring the stability of the drip trough to be welded when it is placed on the upper surface of the placement table 1.

[0045] Since the gas source 142 can push the moving seat 2 on one side to move and drive the top column 242 in a positioning cylinder 241 to move, the round tube can be fixed by the top column 242 in the positioning cylinder 241 on one side, but the drip groove to be welded needs to be clamped by the moving baffles 22 on both sides. In order to achieve the purpose that the gas source 142 can drive the moving seats 2 on both sides to move synchronously, the following features are specifically set:

[0046] An extension block 27 is provided at the center position of the bottom of each moving seat 2, and an avoidance groove 16 extending along the moving path of the extension block 27 is provided on the placement table 1, and the extension block 27 extends through the avoidance groove 16 to the bottom of the placement table 1; racks 271 extending along the length direction of the avoidance groove 16 are respectively installed on the extension blocks 27 of the two moving seats 2, and the tooth grooves of the two racks 271 are arranged opposite to each other and are meshed and connected with the rotating gear 17 rotatably installed at the bottom of the placement table 1.

[0047] In this embodiment, the extension block 27 at the bottom of each movable seat 2 extends to the bottom of the placement table 1 through the avoidance groove 16 on the placement table 1, and the rack 271 on the extension block 27 is meshed and connected with the rotating gear 17 rotatably installed at the bottom of the placement table 1. Therefore, when the gas source 142 drives the movable seat 2 on one side to move, the rack 271 drives the rotating gear 17 to rotate, thereby driving the rack 271 and the movable seat 2 on the other side to move synchronously and in the opposite direction, thereby realizing the centering clamping of the two movable seats 2 and positioning the drip groove to be welded.

[0048] In order to solve the problem of how to adjust the position of the movable blocking bar 22 on the first rectangular frame 21, the following features are specifically set:

[0049] A first sliding groove 211 (such as Fig.12 As shown), the depth of the first slide groove 211 is the same as the thickness of the moving baffle 22, and the moving baffle 22 is slidably installed in the first slide groove 211; the upper and lower ends of the first slide groove 211 are respectively provided with first waist-shaped holes 212, and the first waist-shaped holes 212 extend horizontally along the length direction of the moving seat 2, and the upper and lower ends of the moving baffle 22 are respectively provided with horizontal first threaded rods 221, and the first threaded rod 221 passes through the first waist-shaped holes 212. The end of the first threaded rod 221 away from the moving baffle 22 is spirally installed with a first locking bolt 222, and the first locking bolt 222 is used to lock the position of the moving baffle 22.

[0050] The movable stop bar 22 in the present embodiment is slidably installed in the first slide groove 211 on the first rectangular frame 21. The thickness of the movable stop bar 22 is the same as the depth of the first slide groove 211. Therefore, the movable stop bar 22 can keep the surface of the movable stop bar 22 flush with the surface of the first rectangular frame 21 in the first slide groove 211. Therefore, it can be ensured that when the first rectangular frame 21 fits the frame of the drip groove to be welded, the movable stop bar 22 can also fit the two sides of the panel. When the movable stop bar 22 moves in the first rectangular frame 21, the first threaded rods 221 at both ends of the movable stop bar 22 move in the first waist-shaped holes 212 in the first slide groove 211. When the movable stop bar 22 moves to a suitable position, the staff can rotate the first locking bolt 222 to install it on the first threaded rod 221 until the first locking bolt 222 fits the first rectangular frame 21 to lock the position of the movable stop bar 22. The position of the movable stop bar 22 can be adjusted to ensure that the present embodiment can process drip grooves to be welded of various sizes, thereby improving the scope of application of the equipment.

[0051] In order to solve the problem of how to fix the panel from top to bottom, the following features are specifically set:

[0052] A threaded hole 223 is disposed at the upper end of the movable blocking bar 22 . The axis of the threaded hole 223 is vertically disposed. A second threaded rod 224 is spirally installed in the threaded hole 223 . A pressing plate 225 is connected to the bottom end of the second threaded rod 224 .

[0053] In the present embodiment, each movable baffle 22 is provided with a threaded hole 223. The second threaded rod 224 in the rotating threaded hole 223 can drive the pressing plate 225 at the bottom end of the second threaded rod 224 to move in the vertical direction. After the movable baffle 22 is attached to both sides of the drip trough to be welded, the staff can rotate the second threaded rod 224 to make the pressing plate 225 attached to the upper side of the panel to fix the panel, thereby further ensuring the stability of the contact position between the panel and the round tube during welding.

[0054] In order to solve the problem of how to fix the position of the positioning cylinder 241 after the positioning cylinder 241 fixes the position of the round tube, the following features are specifically provided:

[0055] The first rectangular frame 21 is provided with a vertically extending second slide groove 213 at both ends of a side away from the movable baffle 22, and a vertically extending second waist-shaped hole 214 is provided in the second slide groove 213; the two ends of the second rectangular frame 23 are slidably installed in the second slide groove 213, and the two ends of the second rectangular frame 23 are respectively provided with a horizontal third threaded rod 231, the axis of the third threaded rod 231 is perpendicular to the second slide groove 213, the diameter of the third threaded rod 231 is the same as the width of the second waist-shaped hole 214, the third threaded rod 231 passes through the second waist-shaped hole 214, and the third threaded rod 231 is spirally installed at one end away from the second rectangular frame 23 with a third locking bolt 232, and the third locking bolt 232 is used to lock the position of the second rectangular frame 23 on the second slide groove 213.

[0056] The sliding plate 24 in this embodiment is slidably installed on the second rectangular frame 23. The sliding plate 24 can have a certain damping feeling when moving on the second rectangular frame 23. The two ends of the second rectangular frame 23 are limitedly installed in the second slide groove 213 on the first rectangular frame 21. When the second rectangular frame 23 moves in the second slide groove 213 along the vertical direction, the third threaded rods 231 at both ends of the second rectangular frame 23 move in the second waist-shaped holes 214 of the second slide groove 213. The staff can rotate the third locking bolt 232 on the third threaded rod 231 after the top column 242 fits the inner wall of the round tube, so that the third locking bolt 232 fits the first rectangular frame 21, and fix the position of the second rectangular frame 23, so that the position of the positioning cylinder 241 is stable and will not move during the welding process of the welding head 3, thereby ensuring the stability of the round tube.

[0057] Working principle: The staff places the drip trough to be welded on the placement table 1, keeps the circular tube axis of the drip trough to be welded parallel to the axis of the positioning tube 241 on the movable seat 2, and the two movable seats 2 on the placement table 1 move horizontally, so that the first rectangular frame 21 approaches the two sides of the drip trough to be welded, until the moving baffles 22 on the two first rectangular frames 21 fit with the two sides of the drip trough to be welded, thereby clamping and fixing the drip trough to be welded.
