Description

Technical Field

[0001] The invention belongs to the technical field of sled crossbeam manufacturing, and in particular relates to a sled crossbeam welding turning platform. Background Art

[0002] The sled crossbeam is an important component of the sled, mainly used to connect and support the various parts of the sled. In the design of the large sled used in Antarctic transportation, the crossbeam plays an important role as one of the key structures. The design of the sled crossbeam takes into account many factors, including the strength of the material, the low temperature resistance and the rationality of the structure. In the design of the large sled, the crossbeam not only needs to bear the weight from the upper platform of the sled, but also needs to ensure stability and durability in the harsh Antarctic environment. Therefore, the material selection and structural design of the crossbeam have been carefully calculated and considered.

[0003] Welding is a common method in the manufacture of sled crossbeams. The quality of welding is directly related to the overall quality and use effect of the sled. During the welding process of sled crossbeams, vibration is a common and troubling problem. This vibration will not only cause problems such as poor weld formation and reduced welding accuracy, but long-term vibration is more likely to cause fatigue damage to the workpiece material, reducing its mechanical properties and service life.

[0004] Therefore, it is urgent to provide a sled crossbeam welding turning platform to solve the above problems. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the disadvantages of the prior art and provide a sled crossbeam welding turning platform.

[0006] The technical solution adopted to solve the above technical problems is: to provide a sled crossbeam welding turning platform, including a bottom plate, a symmetrical support frame is slidably connected to the surface of the bottom plate, a placement table for placing the sled crossbeam is rotatably connected to the surface of the support frame, and also includes; A symmetrical rotating mechanism is rotatably connected inside the placing platform, a plurality of pressing mechanisms for pressing the sled crossbeam are fixedly installed on the surface of the rotating mechanism, the fixing mechanism is fixedly installed at the end of the meshing mechanism, and a meshing mechanism is rotatably connected inside the placing platform; A fixing mechanism for fixing both sides of the sled crossbeam is slidably connected inside the placing platform, a limiting mechanism for limiting the rotation of the rotating mechanism is slidably connected inside the placing platform, a driving mechanism for rotating the placing platform is fixedly installed on one side of the support frame, and a lifting mechanism for adjusting the height of the placing platform is provided inside the support frame; The rotating mechanism is used to drive the pressing mechanism to flip over. After the flipping is completed, the pressing mechanism presses the surface of the sled beam. During the flipping process, the pressing mechanism and the meshing mechanism are movably fitted and squeezed. The meshing mechanism rotates to push the fixing mechanism out from the inside of the placement table and fix both sides of the sled beam.

[0007] The present invention is further configured as follows: a placement groove is provided on the surface of the placement table, a first spring is fixedly installed at the bottom of the placement groove, a support plate is fixedly installed at the end of the first spring, the support plate is slidably connected inside the placement groove, working grooves are provided on both sides of the placement table, symmetrical grooves are provided on both sides of the placement table, symmetrical rotating shaft grooves are provided inside the working grooves, symmetrical guide rails are fixedly installed inside the working grooves, and symmetrical fixing blocks are fixedly installed on the surface of the placement table.

[0008] Through the above technical scheme, one end of the sled beam is placed on the surface of the support plate through the placement groove. Due to the weight of the sled beam itself, the first spring is squeezed. During welding, the first spring plays a buffering role on the sled beam. The setting of the working groove provides a rotation space for the rotating mechanism and enables the first rack and the second rack of the meshing mechanism to slide inside the working groove. After the long fixed plate is rotated vertically, it can be placed inside the groove. The shaft groove cooperates with the shaft to enable the rotating mechanism to rotate. The setting of the guide rail cooperates with the guide groove to enable the fixing mechanism to move out of the working groove to squeeze and fix both sides of the sled beam. The fixing block is hinged to the U-shaped frame so that the U-shaped frame can rotate at a small angle.

[0009] The present invention is further configured as follows: the rotating mechanism includes a first connecting rod, a symmetrical long fixed plate and a short fixed plate are fixedly installed on the surface of the first connecting rod, the long fixed plate and the short fixed plate are at a right angle, a slot is opened on one side of the surface of the short fixed plate, a rotating shaft is fixedly installed inside the first connecting rod, the first connecting rod and the short fixed plate are rotatably connected inside the working groove, the long fixed plate is rotatably connected inside the groove, and the rotating shaft is rotatably connected inside the rotating shaft groove.

[0010] Through the above technical solution, when the sled crossbeam is placed inside the placement groove, the lower surface contacts the short fixed plate to squeeze the short fixed plate, and the short fixed plate rotates after being squeezed, so that the first connecting rod rotates, and the long fixed plate rotates from a vertical state to a horizontal state. At this time, the pressing mechanism contacts the front side of the sled crossbeam and presses the front side of the sled crossbeam. The cooperation between the card slot and the card block prevents the first connecting rod from rotating, so that the pressing mechanism can continue to press the sled crossbeam, and the two ends of the rotating shaft are inserted into the rotating shaft slot, so that the first connecting rod can drive the long fixed plate and the short fixed plate to rotate.

[0011] The present invention is further configured as follows: the pressing mechanism includes a fixed rod, the fixed rod is fixedly installed on the surface of the long fixed plate, a first positioning ring is fixedly installed on one end of the fixed rod, a first sleeve is slidably connected to the surface of the fixed rod, the first positioning ring is slidably connected to the inside of the first sleeve, a second spring is fixedly installed on the surface of the first positioning ring, the other end of the second spring is fixedly connected to one end inside the first sleeve, an abutment plate is fixedly installed on the surface of the first sleeve, and a plurality of hemispherical blocks are fixedly installed on the surface of the abutment plate.

[0012] Through the above technical scheme, when the sled beam is welded on the front side, the pressing mechanism presses the sled beam, and when the sled beam is flipped over, the abutment plate lifts the sled beam. When welding on the reverse side, the vibration of the sled beam is damped by the setting of the first sleeve and the second spring, and the setting of the hemispherical block increases the friction with the front side of the sled beam, thereby effectively pressing the sled beam.

[0013] The present invention is further configured as follows: the meshing mechanism includes a first rack, the first rack is slidably connected to the inside of a working groove, a symmetrical second sleeve is fixedly installed inside the working groove, a second positioning ring is fixedly installed at one end of the first rack, the first rack and the second positioning ring are both slidably connected to the inside of the second sleeve, a third spring is fixedly installed on the surface of the second positioning ring, the other end of the third spring is fixedly connected to one end inside the second sleeve, a symmetrical rotating rod is rotatably connected to the inside of the working groove, a gear is fixedly installed on the surface of the rotating rod, one side of the gear is meshed with the first rack, a second rack is slidably connected to the inside of the working groove, and the other side of the gear is meshed with the second rack.

[0014] Through the above technical solution, when the short fixed plate rotates, the back side fits with the end of the first rack to squeeze the first rack. After being squeezed, the first rack moves into the working groove, and the meshing action of the first rack and the gear enables the gear to rotate. The gear and the second gear mesh at the same time, so that when the first rack moves into the working groove, the second rack drives the fixing mechanism to move out of the working groove to fix the two sides of the sled crossbeam. The second sleeve provides space for the movement of the first rack and the second positioning ring while ensuring that the first rack will not deviate when moving. The setting of the third spring can enable the first rack to move back to the initial position after the welding work is completed and wait for the next work.

[0015] The present invention is further configured as follows: the fixing mechanism includes a moving block, the end of the second rack is fixedly connected to the surface of the moving block, a fourth spring is fixedly installed inside the moving block, a positioning plate is fixedly installed on the end of the fourth spring, a second connecting rod is fixedly installed on the surface of the positioning plate, the second connecting rod and the positioning plate are both slidably connected inside the moving block, a pressing plate is fixedly installed on the end of the second connecting rod, a symmetrical guide groove is opened on the lower surface of the moving block, and the guide rail is slidably connected inside the guide groove.

[0016] Through the above technical solution, when the second rack moves, it pushes the moving block out of the working groove, the pressing plate contacts and presses the two sides of the sled beam, and the fourth spring and the positioning plate are matched to enable the pressing plate to press both sides of the sled beams of different widths. The guide groove and the guide rail are matched to enable the moving block to remain stable during movement and to move out between the two short fixed plates.

[0017] The present invention is further configured as follows: the limiting mechanism includes a U-shaped frame, the U-shaped frame is hinged to a fixed block, both ends of the U-shaped frame are fixedly connected with movable rods, the ends of the movable rods are fixedly installed with clamping blocks, the clamping blocks are slidably connected inside the clamping slot, a third positioning ring is fixedly installed on the surface of the movable rod, a fifth spring is fixedly installed on the surface of the third positioning ring, a positioning slot is provided inside the placing table, the movable rod and the third positioning ring are both slidably connected inside the positioning slot, the other end of the fifth spring is fixedly connected to one end inside the positioning slot, a yielding slot is provided on one side of the positioning slot, and the clamping block is slidably connected inside the yielding slot.

[0018] Through the above technical solution, when the short fixed plate rotates, the card block is squeezed and temporarily retracted into the yield groove. When the short fixed plate rotates to the inside of the working groove, the card block pops out and is inserted into the card slot under the action of the fifth spring to limit the short fixed plate and prevent the short fixed plate from rotating. When the front and back sides of the sled beam are welded, the U-shaped frame and the fixed block are hinged. At this time, the surface of the U-shaped frame is pressed, and the two ends of the U-shaped frame are away from the surface of the placement table, thereby driving the two movable rods to move out of the positioning groove, and then driving the card block to move out of the card slot to cancel the limitation of the short fixed plate. The sled beam moves out of the two placement grooves by its own weight and falls to the surface of the bottom plate.

[0019] The present invention is further configured as follows: the driving mechanism comprises a turntable, a transmission rod is fixedly mounted on the surface of the turntable, a rotating seat is fixedly mounted on the end of the transmission rod, the placement table is fixedly mounted on the surface of the rotating seat, and a latch is movably inserted inside the turntable.

[0020] Through the above technical solution, when the sled beam needs to be flipped, the turntable is rotated, the transmission rod rotates to drive the rotating seat to rotate, and then drives the placement table to rotate, thereby realizing the flipping of the sled beam. After the flipping of the sled beam is completed, the turntable can be fixed by the cooperation of the pin and the socket, so that the angle of the placement table can be fixed to avoid rotation. There are multiple sockets, and the sled beam can be flipped at multiple angles, which provides convenience for welding work.

[0021] The present invention is further configured as follows: the lifting mechanism comprises a cylinder, a hollow sleeve is fixedly mounted on the end of the cylinder, and the transmission rod is rotatably connected inside the hollow sleeve.

[0022] Through the above technical solution, when the cylinder is raised or lowered, the two placement tables can be driven to adjust their heights. The setting of the hollow sleeve enables the placement tables to still rotate after the positions are adjusted.

[0023] The present invention is further configured as follows: a motor is fixedly mounted on the surface of the base plate, a bidirectional screw rod is transmission-connected to the output end of the motor, a screw sleeve is fixedly mounted on the lower surface of the support frame, the screw sleeve is threadedly connected to the surface of the bidirectional screw rod, a screw sleeve groove is provided on the surface of the base plate, the screw sleeve is slidably connected inside the screw sleeve groove, a through groove is provided inside the support frame, the cylinder is fixedly mounted inside the through groove, a plurality of insertion holes are provided on one side of the support frame and are distributed in a ring shape, and the latch is movably inserted inside the insertion hole.

[0024] Through the above technical solution, the bidirectional screw can be rotated through the setting of the motor, and the distance between the two support frames can be adjusted through the cooperation of the screw sleeve and the screw sleeve groove. It is suitable for welding sled beams of different lengths, and the through groove provides moving space for adjusting the height of the placement table.

[0025] The beneficial effects of the present invention are as follows: 1. The present invention is provided with a rotating mechanism and a pressing mechanism. Under the effect of the gravity of the sled crossbeam itself, the pressing mechanism effectively presses the sled crossbeam when the rotating mechanism rotates, thereby improving the stability of the sled crossbeam. The first spring and the supporting plate are arranged to reduce vibration when the sled crossbeam is welded on the front side. When the sled crossbeam is turned over, the pressing mechanism supports the sled crossbeam. The second spring and the first sleeve are arranged to reduce vibration when the sled crossbeam is welded on the back side. The supporting plate squeezes the back side of the sled crossbeam, thereby improving the stability of the sled crossbeam on the back side, thereby improving the overall quality of the sled crossbeam. 2. The present invention is provided with a lifting mechanism, which can adjust the heights of the two placement platforms. In the initial state, the placement platform is at the lowest height, which is convenient for placing the sled crossbeam, thereby avoiding the staff from artificially lifting the sled crossbeam and improving the welding efficiency. When the sled crossbeam is welded, the placement platform is moved to the lowest height again, which is convenient for the staff to remove the sled crossbeam; 3. The present invention is provided with a driving mechanism. When the driving mechanism is in operation, it drives the two placement tables to rotate. When a welding position on the surface of the sled beam is relatively special, the placement table is rotated by a turntable, and the special welding position is rotated to an angle that is convenient for welding. Then, the angle of the special welding position can be continuously maintained until the welding work is completed through the cooperation of the pin and the socket, thereby improving the welding efficiency and ensuring the quality of the sled beam.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] See also Figure 1-Figure 13 The present application provides a sled crossbeam welding flip platform, including a base plate 1, a symmetrical support frame 2 is slidably connected to the surface of the base plate 1, and a placement table 3 for placing the sled crossbeam is rotatably connected to the surface of the support frame 2.

[0030] like Figure 3 and Figure 4 As shown, a placement groove 31 is provided on the surface of the placement table 3, a first spring 32 is fixedly installed at the bottom of the placement groove 31, a support plate 33 is fixedly installed at the end of the first spring 32, and the support plate 33 is slidably connected inside the placement groove 31, working grooves 34 are provided on both sides of the placement table 3, symmetrical grooves 35 are provided on both sides of the placement table 3, symmetrical rotating shaft grooves 36 are provided inside the working grooves 34, symmetrical guide rails 37 are fixedly installed inside the working grooves 34, and symmetrical fixing blocks 38 are fixedly installed on the surface of the placement table 3.

[0031] Further, in this embodiment, one end of the sled beam is placed on the surface of the support plate 33 through the placement groove 31. Due to the weight of the sled beam itself, the first spring 32 is squeezed. During welding, the first spring 32 acts as a buffer for the sled beam. The setting of the working groove 34 provides a rotation space for the rotating mechanism 4 and enables the first rack 61 and the second rack 67 of the meshing mechanism 6 to slide inside the working groove 34. The long fixed plate 42 can be placed inside the groove 35 after vertical rotation. The shaft groove 36 cooperates with the shaft 45 to enable the rotating mechanism 4 to rotate. The setting of the guide rail 37 cooperates with the guide groove 76 to enable the fixing mechanism 7 to move out of the working groove 34 to squeeze and fix both sides of the sled beam. The fixing block 38 is hinged to the U-shaped frame 81 so that the U-shaped frame 81 can rotate at a small angle.

[0032] like Figure 2 and Figure 8 As shown, a motor 11 is fixedly mounted on the surface of the base plate 1, and a bidirectional screw rod 12 is transmission-connected to the output end of the motor 11, a screw sleeve 23 is fixedly mounted on the lower surface of the support frame 2, and the screw sleeve 23 is threadedly connected to the surface of the bidirectional screw rod 12, a screw sleeve groove 13 is provided on the surface of the base plate 1, and the screw sleeve 23 is slidably connected inside the screw sleeve groove 13, a through groove 21 is provided inside the support frame 2, and a cylinder 101 is fixedly mounted inside the through groove 21, and a plurality of insertion holes 22 are provided on one side of the support frame 2 and are distributed in a ring shape, and a latch 94 is movably inserted inside the insertion hole 22.

[0033] This embodiment further enables the bidirectional screw rod 12 to rotate through the setting of the motor 11, and the distance between the two support frames 2 can be adjusted through the cooperation of the screw sleeve 23 and the screw sleeve groove 13, which is suitable for welding sled beams of different lengths. The through groove 21 provides a movable space for adjusting the height of the placement table 3.

[0034] A symmetrical rotating mechanism 4 is rotatably connected inside the placement platform 3 , and a plurality of pressing mechanisms 5 for pressing the sled cross beams are fixedly mounted on the surface of the rotating mechanism 4 . An engaging mechanism 6 is rotatably connected inside the placement platform 3 .

[0035] like Figure 7 As shown, the rotating mechanism 4 includes a first connecting rod 41, and a symmetrical long fixed plate 42 and a short fixed plate 43 are fixedly installed on the surface of the first connecting rod 41. The long fixed plate 42 and the short fixed plate 43 are at a right angle. A slot 44 is opened on one side of the surface of the short fixed plate 43. A rotating shaft 45 is fixedly installed inside the first connecting rod 41. The first connecting rod 41 and the short fixed plate 43 are rotatably connected inside the working groove 34, the long fixed plate 42 is rotatably connected inside the groove 35, and the rotating shaft 45 is rotatably connected inside the rotating shaft groove 36.

[0036] Furthermore, in this embodiment, when the sled crossbeam is placed inside the placement groove 31, the lower surface contacts the short fixed plate 43 to squeeze the short fixed plate 43, and the short fixed plate 43 is rotated after being squeezed, so that the first connecting rod 41 rotates, and the long fixed plate 42 rotates from a vertical state to a horizontal state. At this time, the pressing mechanism 5 contacts the front of the sled crossbeam and presses the front of the sled crossbeam, and the groove 44 cooperates with the block 83 to prevent the first connecting rod 41 from rotating, so that the pressing mechanism 5 can continue to press the sled crossbeam, and the two ends of the rotating shaft 45 are inserted into the rotating shaft groove 36, so that the first connecting rod 41 can drive the long fixed plate 42 and the short fixed plate 43 to rotate.

[0037] like Figure 7 and Fig.13 As shown, the pressing mechanism 5 includes a fixed rod 51, which is fixedly mounted on the surface of the long fixed plate 42, a first positioning ring 52 is fixedly mounted on one end of the fixed rod 51, a first sleeve 53 is slidably connected to the surface of the fixed rod 51, the first positioning ring 52 is slidably connected to the inside of the first sleeve 53, a second spring 54 is fixedly mounted on the surface of the first positioning ring 52, the other end of the second spring 54 is fixedly connected to one end inside the first sleeve 53, an abutment plate 55 is fixedly mounted on the surface of the first sleeve 53, and a plurality of hemispherical blocks 56 are fixedly mounted on the surface of the abutment plate 55.

[0038] Furthermore, in this embodiment, when the sled beam is welded on the front side, the pressing mechanism 5 presses the sled beam. When the sled beam is flipped over, the abutment plate 55 lifts the sled beam. When the reverse side is welded, the vibration of the sled beam is damped by the arrangement of the first sleeve 53 and the second spring 54. The arrangement of the hemispherical block 56 increases the friction with the front side of the sled beam, thereby effectively pressing the sled beam.

[0039] like Figure 5 and Fig. 9 As shown, the meshing mechanism 6 includes a first rack 61, which is slidably connected to the inside of the working groove 34, and a symmetrical second sleeve 62 is fixedly installed inside the working groove 34. A second positioning ring 63 is fixedly installed at one end of the first rack 61, and the first rack 61 and the second positioning ring 63 are both slidably connected to the inside of the second sleeve 62. A third spring 64 is fixedly installed on the surface of the second positioning ring 63, and the other end of the third spring 64 is fixedly connected to one end inside the second sleeve 62. A symmetrical rotating rod 65 is rotatably connected to the inside of the working groove 34, and a gear 66 is fixedly installed on the surface of the rotating rod 65, and one side of the gear 66 meshes with the first rack 61, and a second rack 67 is slidably connected to the inside of the working groove 34, and the other side of the gear 66 meshes with the second rack 67.

[0040] Furthermore, in this embodiment, when the short fixed plate 43 rotates, the back side fits against the end of the first rack 61 to squeeze the first rack 61. After being squeezed, the first rack 61 moves into the working groove 34, and the meshing action of the first rack 61 and the gear 66 enables the gear 66 to rotate. The gear 66 meshes with the second rack 67 at the same time, so that when the first rack 61 moves into the working groove 34, the second rack 67 drives the fixing mechanism 7 to move out of the working groove 34 to fix the two sides of the sled crossbeam. The second sleeve 62 provides space for the movement of the first rack 61 and the second positioning ring 63 while ensuring that the first rack 61 will not deviate when moving. The setting of the third spring 64 enables the first rack 61 to move back to the initial position after the welding work is completed and wait for the next work to be used.

[0041] The placing platform 3 is internally slidably connected with a fixing mechanism 7 for fixing both sides of the sled crossbeam, the fixing mechanism 7 is fixedly installed at the end of the meshing mechanism 6, the placing platform 3 is internally slidably connected with a limiting mechanism 8 for limiting the rotation of the rotating mechanism 4, a driving mechanism 9 for rotating the placing platform 3 is fixedly installed on one side of the support frame 2, and a lifting mechanism 10 for adjusting the height of the placing platform 3 is arranged inside the support frame 2.

[0042] like Figure 5 and Figure 6 As shown, the fixing mechanism 7 includes a moving block 71, the end of the second rack 67 is fixedly connected to the surface of the moving block 71, a fourth spring 72 is fixedly installed inside the moving block 71, a positioning plate 73 is fixedly installed at the end of the fourth spring 72, a second connecting rod 74 is fixedly installed on the surface of the positioning plate 73, the second connecting rod 74 and the positioning plate 73 are both slidably connected inside the moving block 71, a pressing plate 75 is fixedly installed at the end of the second connecting rod 74, and a symmetrical guide groove 76 is opened on the lower surface of the moving block 71, and the guide rail 37 is slidably connected inside the guide groove 76.

[0043] Furthermore, in this embodiment, when the second rack 67 moves, it pushes the moving block 71 to move out from the inside of the working groove 34, and the pressing plate 75 contacts and presses the two sides of the sled beam. The fourth spring 72 and the positioning plate 73 are arranged in cooperation, so that the pressing plate 75 can press the two sides of the sled beams of different widths, and the guide groove 76 and the guide rail 37 are arranged in cooperation, so that the moving block 71 can remain stable during movement and can move out between the two short fixed plates 43.

[0044] like Figure 4 and Fig.10As shown, the limiting mechanism 8 includes a U-shaped frame 81, which is hinged to the fixed block 38, and the two ends of the U-shaped frame 81 are fixedly connected with movable rods 82, and the ends of the movable rods 82 are fixedly installed with clamping blocks 83, and the clamping blocks 83 are slidably connected inside the clamping groove 44. A third positioning ring 84 is fixedly installed on the surface of the movable rod 82, and a fifth spring 85 is fixedly installed on the surface of the third positioning ring 84. A positioning groove 86 is opened inside the placement table 3, and the movable rod 82 and the third positioning ring 84 are both slidably connected inside the positioning groove 86. The other end of the fifth spring 85 is fixedly connected to one end inside the positioning groove 86, and a yield groove 87 is opened on one side of the positioning groove 86, and the clamping block 83 is slidably connected inside the yield groove 87.

[0045] Furthermore, in this embodiment, when the short fixed plate 43 rotates, the block 83 is squeezed and temporarily retracted into the clearance groove 87. When the short fixed plate 43 rotates to the inside of the working groove 34, the block 83 pops out and is inserted into the slot 44 under the action of the fifth spring 85 to limit the short fixed plate 43 and prevent the short fixed plate 43 from rotating. When the front and back sides of the sled beam are welded, the U-shaped frame 81 and the fixed block 38 are hingedly set. At this time, the surface of the U-shaped frame 81 is pressed, and the two ends of the U-shaped frame 81 are away from the surface of the placement table 3, thereby driving the two movable rods 82 to move out of the positioning groove 86, and then driving the block 83 to move out of the slot 44 to cancel the limitation of the short fixed plate 43. The sled beam moves out of the two placement grooves 31 by its own weight and falls to the surface of the bottom plate 1.

[0046] like Fig. 9 As shown, the driving mechanism 9 includes a turntable 91, a transmission rod 92 is fixedly mounted on the surface of the turntable 91, a rotating seat 93 is fixedly mounted on the end of the transmission rod 92, the placement table 3 is fixedly mounted on the surface of the rotating seat 93, and a latch 94 is movably inserted inside the turntable 91.

[0047] Furthermore, in this embodiment, when the sled beam needs to be flipped, the turntable 91 is rotated, and the transmission rod 92 rotates to drive the rotating seat 93 to rotate, and then drives the placement table 3 to rotate, thereby realizing the flipping of the sled beam. After the flipping of the sled beam is completed, the turntable 91 can be fixed by the cooperation of the pin 94 and the socket 22, so that the angle of the placement table 3 can be fixed to avoid rotation. The socket 22 is set to multiple, and the sled beam is flipped at multiple angles, which provides convenience for welding work.

[0048] like Figure 8 As shown, the lifting mechanism 10 includes a cylinder 101 , a hollow sleeve 102 is fixedly mounted on the end of the cylinder 101 , and the transmission rod 92 is rotatably connected inside the hollow sleeve 102 .

[0049] Furthermore, in this embodiment, when the cylinder 101 is raised or lowered, the two placement tables 3 are driven to adjust their heights. The provision of the hollow sleeve 102 enables the placement tables 3 to still rotate after the positions are adjusted.

[0050] The rotating mechanism 4 is used to drive the pressing mechanism 5 to flip. After the flipping is completed, the pressing mechanism 5 presses the surface of the sled beam. During the flipping process, the pressing mechanism 5 and the meshing mechanism 6 are flexibly fitted and squeezed. The meshing mechanism 6 rotates to push the fixing mechanism 7 out from the inside of the placement table 3 and fix both sides of the sled beam.

[0051] The working principle of this embodiment is as follows: first, the cylinder 101 is started, and the two placement platforms 3 are moved to the lowest height, and the two ends of the sled beam are placed inside the placement platforms 3 respectively, and the lower surface of the sled beam contacts the short fixed plate 43 to squeeze the short fixed plate 43. After being squeezed, the short fixed plate 43 rotates to rotate the first connecting rod 41, and the long fixed plate 42 rotates from a vertical state to a horizontal state. At this time, the pressing mechanism 5 contacts the front of the sled beam and presses the front of the sled beam. When the short fixed plate 43 rotates to the inside of the working groove 34, the block 83 pops out and inserts into the slot 44 under the action of the fifth spring 85 to limit the short fixed plate 43 and prevent the short fixed plate 43 from rotating. The back side of the short fixed plate 43 fits with the end of the first rack 61 to squeeze the first rack 61. After being squeezed, the first rack 61 moves into the working groove 34, and the meshing action of the first rack 61 and the gear 66 enables the gear 66 to rotate. The wheel 66 is meshed with the second rack 67 at the same time, so that when the first rack 61 moves into the working groove 34, the second rack 67 drives the fixing mechanism 7 to move out of the working groove 34 to fix the two sides of the sled beam. After the front welding of the sled beam is completed, the turntable 91 is rotated, and the transmission rod 92 rotates to drive the rotating seat 93 to rotate, thereby driving the placement platform 3 to rotate, thereby realizing the flipping of the sled beam. After the flipping of the sled beam is completed, the turntable 91 can be fixed by the cooperation of the latch 94 and the socket 22. When the front and back welding of the sled beam is completed, the U-shaped frame 81 and the fixed block 38 are hingedly set, and the surface of the U-shaped frame 81 is pressed at this time. The two ends of the U-shaped frame 81 are away from the surface of the placement platform 3, thereby driving the two movable rods 82 to move out of the positioning groove 86, and then driving the card block 83 to move out of the card slot 44 to cancel the limit of the short fixed plate 43. The sled beam moves out of the two placement slots 31 by its own weight and falls to the surface of the bottom plate 1.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
