Description

Technical Field

[0001] The invention relates to the technical field of automobile parts manufacturing, in particular to an automatic unloading and coding mechanism for automobile leaf springs. Background Art

[0002] Leaf spring is the most widely used elastic element in automobile suspension. It has the functions of storing and releasing energy, absorbing vibration and impact energy, etc. Leaf spring is an elastic beam of approximately equal strength composed of several alloy spring leaves of equal width but unequal length (the thickness can be equal or unequal). It is both an elastic element and a guide device of the suspension.

[0003] In the production process of existing leaf springs, it is necessary to combine steel plates produced in different steps. Therefore, the steel plates produced and processed in different steps need to be classified, unloaded and stacked. In this process, manual loading, manual sizing, manual connection and stacking are required. In this process, operators will come into direct contact with the steel plates, which is not only easy to get injured, but also easy to cause the steel plates to fall during the transfer process, causing damage to the steel plates or the ground. At the same time, due to the differences in the sizes of the steel plates, more manpower is required and the factory cost is relatively high. Therefore, the present application provides an automatic unloading and stacking mechanism for automotive leaf springs to meet the needs. Summary of the invention

[0011] Optionally, two rotating shafts are provided, and gears are provided in the middle of the two rotating shafts. The two centrally symmetrical rotating shafts are respectively connected to the two sides of the trigger rod with a serrated structure through gear meshing, and the rotating shafts are rotatably connected in the mounting plate, and one end of the two rotating shafts is rotatably connected to the threaded shaft through a transmission belt.

[0012] Optionally, a group of evenly spaced serrated structures are provided at the bottom of the adjusting block, the top of the adjusting sleeve is fixedly connected to a limiting sleeve, the bottom of the adjusting sleeve is fixedly connected to an auxiliary plate, the auxiliary plate is rotatably connected to a first gear, the first gear is meshed with the serrated structure at the bottom of the adjusting block, the height of the inner wall of the adjusting sleeve is greater than the height of the adjusting block, and the auxiliary plate is slidably connected to the bottom of the mounting plate.

[0013] Optionally, a second piston rod is fixedly connected to the top of the second suction cup, the second piston rod is slidably connected to the second oil storage rod, and an adjustment base is provided on the top of the second oil storage rod.

[0017] In the above scheme, by setting an adjustment component, when the bending curvature of the steel plate is larger, the distance between the two ends and the bottom of the steel plate will be larger. When the mounting plate is blocked by the two ends of the steel plate, the trigger rod will move a longer distance, the number of turns of the rotating shaft and the threaded shaft will increase, the corresponding distance moved by the adjustment block will increase, and the rotation angle of the first gear will increase, thereby increasing the rotation angle of the second suction cup, so that the second suction cup can face the surface of the steel plate. When the bending curvature of the steel plate is smaller, the rotation angle of the second suction cup will be smaller. At this time, the bottom of the second suction cup can still face the surface of the steel plate, so that during the stacking process of the steel plate, the first suction cup and the second suction cup can be stably sucked on the surface of the steel plate. Furthermore, when the first suction cup is sucked on the surface of the steel plate, the two second suction cups gradually extend and eventually adsorb on the surface of the steel plate, so that the steel plate can be more stable when transferred.

[0018] By setting up a moving component, when making leaf springs, multiple groups of steel plates of different lengths are needed. When cutting and stacking steel plates of different lengths, the operator can adjust the distance between the two second suction cups so that the two second suction cups and the first suction cup can be evenly distributed on the surface of the steel plate, so that the steel plate can be evenly stressed during the transfer process, thereby avoiding the situation where the steel plate falls due to greater gravity on one side during the transfer process.

[0019] To sum up, by setting up moving components and adjusting components, steel plates of different lengths and different curvatures can be cut and stacked during the production of leaf springs, which makes the operation simpler, improves the production efficiency of leaf springs, avoids direct contact between operators and steel plates, and protects the safety of operators.

The device may be oriented in other ways, and the spatially relative descriptors used herein may be similarly interpreted accordingly.

[0037] like Figures 1 to 9As shown, an embodiment of the present invention provides an automatic unloading and coding mechanism for automobile leaf springs, comprising a movable slide rail 1, both sides of the movable slide rail 1 are provided with placement boxes 12, an assembly line is placed in the middle of the two placement boxes 12, a telescopic rod 2 is slidably connected to the top of the movable slide rail 1, the telescopic rod 2 is located directly above the assembly line, a trigger rod 3 is fixedly connected to the bottom of the telescopic rod 2, the lower end of the trigger rod 3 is slidably connected to the movable component 4, the movable component 4 is used to adjust the position of the second suction cup 6, the bottom of the trigger rod 3 is fixedly connected to the first suction cup 32, the two sides of the first suction cup 32 are symmetrically provided with second suction cups 6, the second suction cup 6 is meshed and connected to the bottom of the adjusting component 5, the adjusting component 5 is used to change the rotation angle of the second suction cup 6, the adjusting component 5 is rotatably connected to the movable component 4, when in use, the operator needs to move the device to one end of the leaf spring assembly line, and when the steel plate is bent, it will move along the assembly line to the movable component 4. When the first and second suction cups 32 are sucked on the steel plate, the trigger rod 3 will still move downward. In this process, the second suction cup 6 will gradually approach the two ends of the bent steel plate. When the second suction cup 6 is sucked on the surface of the steel plate, the trigger rod 3 stops moving. At this time, the telescopic rod 2 begins to shrink, and the trigger rod 3 will move upward. At this time, the steel plate will move upward synchronously due to being adsorbed by the first suction cup 32 and the second suction cup 6. Then the telescopic rod 2 will move on the moving slide rail 1 and place the steel plate in the placement boxes 12 on both sides, so that the steel plates can be neatly stacked in the placement boxes 12.

[0038] In this embodiment, if Figures 1 to 3 As shown, when the leaf spring is manufactured, part of the steel plate needs to be bent so that the shape of the steel plate can meet the assembly requirements of the leaf spring. After the steel plate is bent, it will be moved through the assembly line to just below the trigger rod 3. At this time, the first suction cup 32 and the second suction cup 6 can be adsorbed on the surface of the steel plate by the descent of the trigger rod 3, so that the steel plate can be more stable during transfer.

[0039] As an implementation method in this embodiment, Figures 4 to 8As shown, a group of uniformly spaced serrated structures are provided on both sides of the trigger rod 3, a first oil storage rod 31 is fixedly connected to the bottom of the trigger rod 3, a first piston rod 311 is slidably connected in the first oil storage rod 31, a first spring 312 is provided between the first piston rod 311 and the first oil storage rod 31, a first suction cup 32 is fixedly connected to the bottom of the first piston rod 311, the adjustment component 5 includes a rotating shaft 51, one end of the rotating shaft 51 is rotatably connected to a threaded shaft 52, an adjustment block 53 is rotatably connected to the threaded shaft 52, an adjustment sleeve 54 is slidably connected to the adjustment block 53, two rotating shafts 51 are provided, gears are provided in the middle of the two rotating shafts 51, two centrally symmetrical rotating shafts 51 are respectively connected to the two sides of the trigger rod 3 provided with the serrated structure through gear meshing, the rotating shaft 51 is rotatably connected to the mounting plate 41, one end of the two rotating shafts 51 is rotatably connected to the threaded shaft 52 through a transmission belt 511, and a group of uniformly spaced serrated structures are provided at the bottom of the adjustment block 53, The top of the adjusting sleeve 54 is fixedly connected to the limiting sleeve 541, and the bottom of the adjusting sleeve 54 is fixedly connected to an auxiliary plate 543. The auxiliary plate 543 is rotatably connected to the first gear 542, and the first gear 542 is meshed with the serrated structure at the bottom of the adjusting block 53. The auxiliary plate 543 is slidably connected to the bottom of the mounting plate 41. The top of the second suction cup 6 is fixedly connected to the second piston rod 611, and the second piston rod 611 is slidably connected to the second oil storage rod 61. An adjusting base 62 is provided at the top of the second oil storage rod 61. The adjusting base 62 is fixedly connected to the second gear 621 through a supporting shaft. The second gear 621 is rotatably connected to the auxiliary plate 543 through a supporting shaft. A serrated structure is provided on one side of the surface of the second gear 621, and the second gear 621 is meshed with the first gear 542. Both sides of the first oil storage rod 31 are respectively connected to the second oil storage rod 61 through a hose. When the trigger rod 3 descends under the action of the telescopic rod 2, the mounting plate 41 will move downward synchronously with the trigger rod 3.

[0040] When the bottom of the mounting plate 41 contacts the raised ends of the steel plate, the mounting plate 41 will be supported on the steel plate. At this time, the trigger rod 3 will continue to move downward under the action of the telescopic rod 2. During the movement of the trigger rod 3, the rotating shaft 51 meshed with the two sides of the trigger rod 3 starts to rotate. When the rotating shaft 51 rotates, the threaded shaft 52 will be driven to rotate through the transmission belt 511. When the threaded shaft 52 rotates, the adjusting block 53 threadedly connected to the threaded shaft 52 will slide in the mounting plate 41. When the adjusting block 53 slides, since the adjusting sleeve 54 is fixed to the mounting plate 41 by the positioning bolt 42, the first gear 542 meshed with the bottom of the adjusting block 53 starts to rotate. When the first gear 542 rotates, it will drive the second gear 621 to rotate. When the second gear 621 rotates, it will be fixed with the second gear 621. The connected adjusting base 62 starts to rotate, thereby changing the angle of the second suction cup 6, so that the bottom of the second suction cup 6 can face the surface of the steel plate. When the first suction cup 32 contacts the surface of the steel plate, the trigger rod 3 will still move downward. At this time, the oil in the first oil storage rod 31 at the bottom of the trigger rod 3 will be squeezed by the first piston rod 311, and the oil in the first oil storage rod 31 will be squeezed into the second oil storage rod 61 through the hose. When the oil enters the second oil storage rod 61, it will push the second piston rod 611 to extend the second piston rod 61. Correspondingly, the second suction cup 6 will gradually approach the steel plate. When the second suction cup 6 is sucked on the steel plate, the second piston rod 611 cannot extend, and the volume of oil in the first oil storage rod 31 and the second oil storage rod 61 remains relatively stable, and the first suction cup 32 and the second suction cup 6 are both sucked on the surface of the steel plate.

[0041] At this time, the telescopic rod 2 begins to shrink, causing the trigger rod 3 to move upward. Since the two second suction cups 6 are sucked on the two ends of the steel plate and the first suction cup 32 is sucked in the middle of the steel plate, the steel plate will move upward with the movement of the trigger rod 3, and will eventually be placed in the placement box 12 by the telescopic rod 2. When the steel plate reaches the specified position, the first suction cup 32 and the second suction cup 6 will lose suction at the same time. At this time, the steel plate will fall at the specified position. At this time, the mounting plate 41 will fall on the lower end of the trigger rod 3 under the influence of gravity. During this process, the rotating shaft 51 and the threaded shaft 52 will rotate in opposite directions, thereby causing the adjusting block 53 to move in the opposite direction and restoring the second suction cup 6 to its initial angle. At the same time, the first spring 312 begins to extend, causing the first piston rod 311 to move in the opposite direction and draw the oil in the second oil storage rod 61 back into the first oil storage rod 31, so that the first suction cup 32 and the second suction cup 6 are restored to their initial heights.

[0042] In this embodiment, if Figures 4 to 8As shown, when the bending curvature of the steel plate is larger, the distance between the two ends and the bottom of the steel plate will be larger. When the mounting plate 41 is blocked by the two ends of the steel plate, the trigger rod 3 will move a longer distance. When the trigger rod 3 moves a longer distance, the number of turns of the rotating shaft 51 and the threaded shaft 52 will increase, the corresponding moving distance of the adjusting block 53 will increase, and the rotation angle of the first gear 542 will increase, thereby increasing the rotation angle of the second suction cup 6, so that the second suction cup 6 can face the surface of the steel plate. When the bending curvature of the steel plate is smaller, the rotation angle of the second suction cup 6 will be smaller. At this time, the bottom of the second suction cup 6 can still face the surface of the steel plate, so that during the stacking process of the steel plate, the first suction cup 32 and the second suction cup 6 can be stably sucked on the surface of the steel plate.

[0043] As an implementation method in this embodiment, Figures 2 to 4 and Figure 6 As shown, the moving assembly 4 includes a mounting plate 41, a first slide groove 43 is provided in the middle of the mounting plate 41, the trigger rod 3 is limitedly slidably connected in the first slide groove 43, both sides of the first slide groove 43 are provided with limiting grooves 411, the limiting groove 411 is fixedly connected to the top of the mounting plate 41, a second slide groove 412 is provided in the limiting groove 411, a positioning bolt 42 is slidably connected in the second slide groove 412, the nut of the positioning bolt 42 is slidably connected in the limiting groove 411, the limiting sleeve 541 is threadedly connected to the positioning bolt 42, the bottom of the positioning bolt 42 is rotatably connected in the limiting sleeve 541, the height of the inner wall of the adjusting sleeve 54 is greater than the height of the adjusting block 53, when the length of the steel plate is long, the operator needs to loosen the positioning bolt 42 by a tool, because the nut of the positioning bolt 42 is limited In the limiting groove 411, the height of the positioning bolt 42 remains unchanged. At this time, the position of the adjusting sleeve 54 in the mounting plate 41 will gradually decrease. When the adjusting sleeve 54 contacts the top of the adjusting block 53, the operator stops turning the positioning bolt 42. At this time, the first gear 542 is separated from the serrated structure at the bottom of the adjusting block 53. The operator adjusts the position of the adjusting sleeve 54 by moving the positioning bolt 42 to increase the distance between the two second suction cups 6. When the position of the second suction cup 6 is determined, the operator tightens the positioning bolt 42 with a tool. At this time, the adjusting sleeve 54 will gradually rise. When the adjusting sleeve 54 contacts the bottom of the adjusting block 53, the first gear 542 will mesh with the serrated structure at the bottom of the adjusting block 53 again, and the operator stops turning the positioning bolt 42.

[0044] In this embodiment, if Figures 2 to 4 and Figure 6As shown, when making leaf springs, multiple groups of steel plates of different lengths are needed. When cutting and stacking steel plates of different lengths, the operator can adjust the distance between the two second suction cups 6 so that the two second suction cups 6 and the first suction cup 32 can be evenly distributed on the surface of the steel plates, so that the steel plates can be evenly stressed during the transfer process, thereby avoiding the situation where the steel plates fall due to greater gravity on one side during the transfer process.

[0045] The working principle of the technical solution provided by the present invention is as follows:

[0046] When in use, the operator needs to move the device to one end of the leaf spring assembly line. After the steel plate is bent, it will move along the assembly line to the bottom of the movable slide rail 1. At this time, the telescopic rod 2 extends, causing the trigger rod 3 to drop. When the bottom of the movable component 4 contacts the two ends of the steel plate, the two ends of the steel plate are raised because the steel plate is in a bent state. At this time, the movable component 4 will be blocked by the steel plate, and the trigger rod 3 will continue to move downward under the action of the telescopic rod 2.

[0047] During this process, the moving component 4 will cause the second suction cup 6 to rotate. When the first suction cup 32 is sucked on the steel plate, the trigger rod 3 will still move downward. During this process, the second suction cup 6 will gradually approach the two ends of the bending of the steel plate. When the second suction cup 6 is sucked on the surface of the steel plate, the trigger rod 3 stops moving. At this time, the telescopic rod 2 begins to shrink, and the trigger rod 3 will move upward. At this time, the steel plate will move upward synchronously due to being adsorbed by the first suction cup 32 and the second suction cup 6. Then the telescopic rod 2 will move on the moving slide rail 1 and place the steel plate in the placement boxes 12 on both sides, so that the steel plates can be neatly stacked in the placement boxes 12. When the steel plate spring is made, part of the steel plate needs to be bent so that the shape of the steel plate can meet the assembly requirements of the steel plate spring.

[0048] After the steel plate is bent, it will move through the assembly line to just below the trigger rod 3. At this time, the first suction cup 32 and the second suction cup 6 can be adsorbed on the surface of the steel plate by the descent of the trigger rod 3, so that the steel plate can be more stable during transfer. When the trigger rod 3 descends under the action of the telescopic rod 2, the mounting plate 41 will move downward synchronously with the trigger rod 3. When the bottom of the mounting plate 41 contacts the raised ends of the steel plate, the mounting plate 41 will be supported on the steel plate. At this time, the trigger rod 3 will continue to move downward under the action of the telescopic rod 2. During the movement of the trigger rod 3, the rotating shaft 51 meshed with the two sides of the trigger rod 3 starts to rotate. When the rotating shaft 51 rotates, the threaded shaft 52 will be driven to rotate through the transmission belt 511. When the threaded shaft 52 rotates, the adjustment block 53 threadedly connected to the threaded shaft 52 will slide in the mounting plate 41.

[0049] When the adjusting block 53 slides, since the adjusting sleeve 54 is fixed to the mounting plate 41 by the positioning bolt 42, the first gear 542 meshed with the bottom of the adjusting block 53 starts to rotate. When the first gear 542 rotates, it drives the second gear 621 to rotate. When the second gear 621 rotates, the adjusting base 62 fixedly connected to the second gear 621 starts to rotate, so that the angle of the second suction cup 6 changes, so that the bottom of the second suction cup 6 can face the surface of the steel plate. When the first suction cup 32 contacts the surface of the steel plate, the trigger rod 3 will still move downward, at this time, the oil in the first oil storage rod 31 at the bottom of the trigger rod 3 will be squeezed by the first piston rod 311, and the oil in the first oil storage rod 31 will be squeezed into the second oil storage rod 61 through the hose. When the oil enters the second oil storage rod 61, it will push the second piston rod 611 to extend the second piston rod 61. Correspondingly, the second suction cup 6 will gradually approach the steel plate. When the second suction cup 6 is sucked on the steel plate, the second piston rod 611 cannot extend, and the volume of oil in the first oil storage rod 31 and the second oil storage rod 61 remains relatively stable.

[0050] The first suction cup 32 and the second suction cup 6 are both sucked on the surface of the steel plate. At this time, the telescopic rod 2 begins to shrink, causing the trigger rod 3 to move upward. Since the two second suction cups 6 are sucked on both ends of the steel plate and the first suction cup 32 is sucked in the middle of the steel plate, the steel plate will move upward with the movement of the trigger rod 3 and will eventually be placed in the placement box 12 by the telescopic rod 2. When the steel plate reaches the designated position, the first suction cup 32 and the second suction cup 6 will lose suction at the same time, and the steel plate will fall to the designated position. At this time, the mounting plate 41 will fall to the lower end of the trigger rod 3 under the influence of gravity. In this process, the rotating shaft 51 and the threaded shaft 52 will rotate in the opposite direction, thereby causing the adjusting block 53 to move in the opposite direction and restoring the second suction cup 6 to its initial angle. When the bending curvature of the steel plate is larger, the distance between the two ends of the steel plate and the bottom will be larger. When the mounting plate 41 is blocked by the two ends of the steel plate, the trigger rod 3 will move a longer distance. When the trigger rod 3 moves a longer distance, the number of revolutions of the rotating shaft 51 and the threaded shaft 52 will increase, and the corresponding moving distance of the adjusting block 53 will increase. The rotation angle of the first gear 542 will increase, thereby increasing the rotation angle of the second suction cup 6, so that the second suction cup 6 can face the surface of the steel plate.

[0051] When the bending curvature of the steel plate is small, the rotation angle of the second suction cup 6 will be small. At this time, the bottom of the second suction cup 6 can still face the surface of the steel plate, so that the first suction cup 32 and the second suction cup 6 can be stably sucked on the surface of the steel plate during the stacking process. When the length of the steel plate is long, the operator needs to loosen the positioning bolt 42 with a tool. Since the nut of the positioning bolt 42 is limited in the limiting groove 411, the height of the positioning bolt 42 remains unchanged. At this time, the position of the adjusting sleeve 54 in the mounting plate 41 will gradually decrease. When the adjusting sleeve 54 contacts the top of the adjusting block 53, the operator stops screwing the positioning bolt 42. At this time, the first gear 542 is separated from the serrated structure at the bottom of the adjusting block 53. The operator adjusts the position of the adjusting sleeve 54 by moving the positioning bolt 42 so that the two When the distance between the two suction cups 6 increases, and when the position of the second suction cup 6 is determined, the operator tightens the positioning bolt 42 with a tool. At this time, the adjusting sleeve 54 will gradually rise. When the adjusting sleeve 54 contacts the bottom of the adjusting block 53, the first gear 542 will again engage with the serrated structure at the bottom of the adjusting block 53, and the operator stops turning the positioning bolt 42. When making leaf springs, multiple groups of steel plates of different lengths are required. When cutting and stacking steel plates of different lengths, the operator can adjust the distance between the two second suction cups 6 so that the two second suction cups 6 and the first suction cup 32 can be evenly distributed on the surface of the steel plate, so that the steel plate can be evenly stressed during the transfer process, thereby avoiding the situation where the steel plate falls due to the greater gravity on one side during the transfer process.
