Abstract
Description
Technical Field
[0001] This invention relates to the field of tensioner assembly technology, and in particular to a folding tensioner assembly table. Background Technology
[0002] In the production of folding tensioners, the assembly of the ratchet cylinder and screw is a core process that directly affects the product's locking accuracy and service life. Industrial robots are now widely used for this assembly during the production process.
[0003] There are many existing technologies for sampling components, such as:
[0004] A Chinese invention patent discloses a folding tensioner, comprising a handle, a pivot, and a ratchet body. The handle includes a handheld portion and a first connecting portion. The ratchet body includes a ratchet, a pawl, and a second connecting portion, the second connecting portion facing the handle and extending beyond the ratchet body. The pivot includes a fixed portion and a rotating portion, the rotating portion being rotatable around the fixed portion. The fixed portion is connected to the second connecting portion of the ratchet body, and the rotating portion is connected to the first connecting portion of the handle, allowing the handle to rotate around the ratchet body, thus forming a folding tensioner with a simple structure and greater space-saving design.
[0005] However, some problems still exist in actual use:
[0006] 1. When assembling the folding tensioner on a traditional assembly table, operators need to manually rotate the screw to complete the assembly with the ratchet cylinder. This is not only labor-intensive, but also inefficient because each person can only operate one side of the screw at a time. In addition, the hook at the end of the screw is easily shaken by centrifugal force during the assembly process, which may hit nearby operators and pose a serious safety hazard.
[0007] 2. In the existing assembly table, during the assembly process of the screw and ratchet cylinder, the rotation of the screw easily causes the ratchet cylinder to rotate synchronously, resulting in a misalignment between the two. This not only reduces the assembly accuracy but also significantly prolongs the assembly time, failing to meet the requirements of efficient production. Summary of the Invention
[0008] In order to overcome the above-mentioned defects in the prior art, the present invention provides a folding tensioner assembly table.
[0009] To achieve the above objectives, the present invention provides a folding tensioner assembly table, comprising a workbench, a frame plate on the top of the workbench, a support base on the surface of the workbench, a roller on the surface of the support base, a ratchet cylinder placed on the surface of the roller, screws mounted on both sides of the ratchet cylinder, hooks at the ends of the screws, clamping assemblies on both sides of the support base for clamping and fixing the ratchet cylinder, an assembly assembly on the top of the frame plate for adjusting the position of the ratchet cylinder to be at the center of the support base surface, the screws being clamped at the ends, the assembly assembly driving the screws to rotate and adapt to the ratchet cylinder for assembly, and protective assemblies on both sides of the frame plate for adaptively stretching the hooks, causing them to move horizontally when the screws drive the hooks to rotate.
[0010] Furthermore, the clamping assembly includes cylindrical columns on both sides of the support base, a sliding rod slidably provided on the inner wall of the cylindrical column, a telescopic spring provided between the cylindrical column and the sliding rod, and a clamping plate provided at the end of the sliding rod, which clamps and limits the ratchet cylinder placed on the surface of the screw on both sides.
[0011] Furthermore, a groove is provided at the bottom of the column, and a toothed block is provided at the bottom of the slide rod. When the slide rod moves, it causes the toothed block to slide in the groove.
[0012] Furthermore, an electric piston rod is provided below the column, and the piston rod at the end of the electric piston rod is provided with a toothed plate, which is controlled to move in the vertical direction to fix the toothed block.
[0013] Furthermore, the assembly component includes a motor mounted on the top of the frame plate. The output end of the motor is provided with a main gear, and there are auxiliary gear rods on both sides of the main gear. Each auxiliary gear rod has a moving block on its surface. When the auxiliary gear rod rotates, it drives the moving blocks to move horizontally.
[0014] Furthermore, a circular rail is provided on one side of the bottom of the moving block, and a moving trolley is provided on the surface of the circular rail. The moving trolley is symmetrical, and an electric cylinder is provided at the end of the moving trolley. A limiting plate is provided on the piston rod at the end of the electric cylinder, and the limiting plate is adapted to the end of the screw.
[0015] Furthermore, the inner wall of the limiting plate is provided with a rubber pad, which is used to increase the friction with the end of the screw.
[0016] Furthermore, the protective assembly includes a base plate disposed on both sides of the inner wall of the frame plate, a sliding column is slidably disposed at the end of the base plate, a rotating frame is disposed between the base plate and the sliding column, a limiting head is rotatably disposed inside the rotating frame, and a rotating roller is disposed between the rotating frame and the limiting head, the rotating roller being arranged in a circular array.
[0017] Furthermore, the outer arm of the frame is equipped with a hydraulic cylinder, and the piston rod at the end of the hydraulic cylinder passes through the frame into its interior. The piston rod at the end of the frame is on the same axis as the sliding column, and controls the piston rod at the end of the frame to push the sliding column to move horizontally.
[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0019] 1. In this folding tensioner assembly table, the end of the screw is placed inside the circular rail. The electric cylinder is controlled to drive the limiting plate to move relative to clamp the end of the screw. After clamping, the electric cylinder is rotated by controlling the moving trolley, so that the screw clamped at the end of the limiting plate rotates coaxially. During the rotation of the limiting plate, the output shaft of the motor drives the main gear to rotate. When the main gear rotates, the auxiliary gear rods on both sides of its bottom mesh and rotate. When the auxiliary gear rods rotate, they drive the moving block to move horizontally. The moving block drives the circular rail to move closer to the ratchet cylinder, realizing automatic assembly of the screw and reducing the labor intensity of the operators.
[0020] 2. In the assembly table of this folding tensioner, the output end of the control motor drives the main gear to rotate. When the main gear rotates, it drives the auxiliary gear rod to mesh and rotate. The moving blocks on the surface of the auxiliary gear rod move relative to each other. Since there is a circular rail at the bottom of the moving block, the relative movement of the circular rail simultaneously controls the electric cylinder to drive the limiting plate to move relative to each other until the end is in contact. During the movement of the moving block, the limiting plate pushes the ratchet cylinder placed on the surface of the roller, so that the ratchet cylinder is at the center of the roller. The assembly components drive the screws on both sides to be assembled simultaneously, which improves the assembly efficiency of the screws.
[0021] 3. In the assembly table of this folding tensioner, when the end of the screw is clamped by the limiting plate, the hook is fastened inside the limiting head. When the screw drives the hook to move, the hook applies a force to the limiting head. Since the screw rotates and drives the hook to rotate, the limiting head is subjected to forces in different directions. The end of the limiting head rotates on the inner wall of the rotating frame under force. Since the screw moves towards the center of the ratchet cylinder during the assembly process, the limiting head is pulled by the tension force to pull the slide column. The slide column moves at the end of the base plate. At the same time, the slide column compresses the compression spring during its movement. When the screw and ratchet cylinder are assembled, the assembled tensioner is unloaded, thereby preventing the hook from swinging during the assembly of the tensioner and avoiding safety hazards.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0038] A folding tensioner assembly table, according to Figure 1-8As shown, the device includes a workbench 1, a frame plate 11 on top of the workbench 1, a support base 12 on the surface of the workbench 1, a roller 13 on the surface of the support base 12, a ratchet cylinder 2 on the surface of the roller 13, screws 21 mounted on both sides of the ratchet cylinder 2, and hooks 22 at the ends of the screws 21. Clamping assemblies 3 are provided on both sides of the support base 12 for clamping and fixing the ratchet cylinder 2. An assembly assembly 4 is provided on the top of the frame plate 11 for adjusting the position of the ratchet cylinder 2 to be at the center of the surface of the support base 12. The screws 21 are clamped at the ends of the assembly assembly 4. The assembly assembly 4 drives the screws 21 to rotate and adapt to the ratchet cylinder 2 for assembly. Protective assemblies 5 are provided on both sides of the frame plate 11 for adaptive stretching of the hooks 22. When the screws 21 drive the hooks 22 to rotate, they move horizontally.
[0039] During the production and assembly of the tensioner, the position of the ratchet cylinder 2 needs to be fixed. Since the ratchet cylinder 2 needs to be clamped frequently during the production process, the clamping assembly 3 includes a column cylinder 31 on both sides of the support base 12. A slide rod 32 is slidably provided on the inner wall of the column cylinder 31. A telescopic spring 33 is provided between the column cylinder 31 and the slide rod 32. A clamping plate 34 is provided at the end of the slide rod 32. The clamping plate 34 clamps and limits the ratchet cylinder 2 placed on the surface of the screw 21. Pushing the clamping plate 34 to move to both sides causes the slide rod 32 to slide on the inner wall of the column cylinder 31. During the sliding process, the slide rod 32 compresses the column cylinder 31 and deforms it, placing the ratchet cylinder 2 on the surface of the roller 13. The push on the clamping plate 34 stops. At this time, the slide rod 32 moves relative to the tension spring 33, limiting the ratchet cylinder 2 on both sides, so that the ratchet cylinder 2 remains stable during the assembly of the screw 21, thereby quickly clamping the ratchet cylinder 2.
[0040] Considering that during the assembly of the tensioner, the ratchet cylinder 2 needs to be rotated into its interior to maintain stability, and that the screw 21 rotating inside the ratchet cylinder 2 can easily cause it to rotate, resulting in low efficiency during assembly, a groove is provided at the bottom of the cylinder 31, and a toothed block 35 is provided at the bottom of the slide rod 32. When the slide rod 32 moves, it causes the toothed block 35 to slide in the groove. An electric piston rod 36 is provided below the cylinder 31, and the piston rod at the end of the electric piston rod 36 is provided with a toothed plate 37. The toothed plate 37 is controlled to move vertically to fix the toothed block 35. When the ratchet cylinder 2 is placed on the surface of the roller 13, the slide rod 32 slides under the force of the extension spring 33. When the ratchet cylinder 2 is installed on the inner wall of the cylinder 31, the clamping plate 34 at the end of the slide rod 32 clamps and fixes both sides of the ratchet cylinder 2. When the slide rod 32 moves, it drives the toothed block 35 to move horizontally in the slide groove. The piston rod at the end of the electric piston rod 36 drives the toothed plate 37 to move vertically, so that the toothed plate 37 and the toothed block 35 are locked and limited. During the assembly process of the ratchet cylinder 2 and the screw 21, the ratchet cylinder 2 can always remain fixed, avoiding the ratchet cylinder 2 from rotating simultaneously due to the rotational friction of the screw 21, thus improving the assembly efficiency of the ratchet cylinder 2 and the screw 21. When the assembly is completed, the piston rod at the end of the electric piston rod 36 drives the toothed plate 37 away from the toothed block 35, thereby facilitating the rapid unloading of the ratchet cylinder 2.
[0041] Considering that the assembly of screw 21 requires workers to rotate it, resulting in high labor intensity, the assembly component 4 includes a motor 41 mounted on top of the frame plate 11. The motor 41 has a main gear 42 at its output end, and auxiliary gear rods 43 on both sides of the main gear 42. Each auxiliary gear rod 43 has a moving block 44 on its surface. When the auxiliary gear rods 43 rotate, they drive the moving blocks 44 to move horizontally. A circular rail 45 is located on one side of the bottom of each moving block 44, and a moving trolley 46 is mounted on the surface of the circular rail 45. The moving trolley 46 is symmetrical and equipped with four sets of rollers, two sets on the top and two sets on the bottom, symmetrically clamping the "workpiece". The upper and lower flanges of the I-beam rail and the rollers are made of polyurethane to reduce friction noise while ensuring clamping force to prevent detachment. An electric cylinder 47 is located at the end of the moving trolley 46. A limiting plate 48 is located on the piston rod at the end of the electric cylinder 47. The limiting plate 48 is adapted to the end of the screw 21. During assembly of the screw 21, the end of the screw 21 is placed inside the circular rail 45, and the electric cylinder 47 is controlled to drive the limiting plate 48 to move relative to clamp the end of the screw 21. After clamping, the movement is controlled... The trolley 46 drives the electric cylinder 47 to rotate, causing the screw 21 clamped at the end of the limiting plate 48 to rotate coaxially. During the rotation of the limiting plate 48, the output shaft of the control motor 41 drives the main gear 42 to rotate. When the main gear 42 rotates, the auxiliary gear rods 43 provided on both sides of its bottom mesh and rotate. When the auxiliary gear rods 43 rotate, they drive the moving block 44 to move horizontally. The moving block 44 drives the circular rail 45 to move closer to the ratchet cylinder 2, thereby realizing automatic assembly of the screw 21 and reducing the labor intensity of the operators.
[0042] To improve assembly efficiency, assembly components 4 are provided on both sides of the ratchet cylinder 2. Before assembling the screw 21, the output end of the control motor 41 drives the main gear 42 to rotate. When the main gear 42 rotates, it drives the secondary gear rod 43 to mesh and rotate. The moving block 44 on the surface of the secondary gear rod 43 moves relative to the main gear. Since the bottom of the moving block 44 is provided with a circular rail 45, the relative movement of the circular rail 45 simultaneously controls the electric cylinder 47 to drive the limiting plate 48 to move relative to the end and fit together. During the movement of the moving block 44, the limiting plate 48 pushes the ratchet cylinder 2 placed on the surface of the roller 13. The clamping plate 34 only limits the ratchet cylinder 2. Therefore, when the rubber pad 49 pushes the ratchet cylinder 2, it moves it to the center of the surface of the roller 13. By controlling the assembly components 4 to drive the screws 21 on both sides to be assembled simultaneously, the assembly efficiency of the screw 21 is improved.
[0043] During the clamping process of the screw 21, in order to increase the friction between the limiting plate 48 and its surface, a rubber pad 49 is provided on the inner wall of the limiting plate 48. The rubber pad 49 is used to increase the friction with the end of the screw 21. When the limiting plate 48 moves relative to clamp the screw 21, the rubber pad 49 is pressed and tightly adheres to the surface of the screw 21. When the moving trolley 46 drives the electric cylinder 47 to rotate on the surface of the circular rail 45, the screw 21 clamped between the rubber pads 49 rotates coaxially, which facilitates quick assembly.
[0044] Because the screw 21 has a hook 22 at its end, when the screw 21 rotates and is assembled on the inner wall of the ratchet cylinder 2, the hook 22 is swung by centrifugal force. During the swinging process, it is easy to hit nearby workers, causing a safety hazard. Therefore, the protective component 5 includes a base plate 51 on both sides of the inner wall of the frame plate 11. The end of the base plate 51 is slidably provided with a sliding column 52. A rotating frame 53 is provided between the base plate 51 and the sliding column 52. The end of the sliding column 52 is provided with a rotating frame 53. A limiting head 55 is rotatably provided inside the rotating frame 53. A rotating roller 54 is provided between the rotating frame 53 and the limiting head 55. The rotating roller 54 is arranged in a circular array. When the end of the screw 21 is clamped by the limiting plate 48, the hook 22 is fastened inside the limiting head 55. When the screw 21 drives the hook 22 to move... During the operation, the hook 22 applies a force to the limiting head 55. As the screw 21 rotates, it drives the hook 22 to rotate, so the limiting head 55 is subjected to forces in different directions. The end of the limiting head 55 rotates on the inner wall of the rotating frame 53 under the force. Since the screw 21 moves towards the center of the ratchet cylinder 2 during the assembly process, the limiting head 55 is pulled by the tension force to pull the slide column 52. The slide column 52 moves to the end of the base plate 51. At the same time, the slide column 52 compresses the compression spring 56 during the movement. When the screw 21 and the ratchet cylinder 2 are assembled, the hook 22 is removed from the end of the limiting head 55, and the assembled tensioner is removed from the surface of the roller 13, thereby preventing the hook 22 from swinging during the assembly of the tensioner and avoiding safety hazards.
[0045] When the ratchet cylinder 2 and screw 21 are assembled, the limiting head 55 is pulled close to the end of the ratchet cylinder 2 by the hook 22. At this time, the compression spring 56 is squeezed by the slide column 52 and generates a large deformation. When the hook 22 needs to be removed from the inside of the limiting head 55, the limiting head 55 needs to be mechanically stretched. This process is labor-intensive. Therefore, the outer arm of the frame plate 11 is equipped with a hydraulic cylinder 57. The piston rod at the end of the hydraulic cylinder 57 passes through the frame plate 11 into its interior. The piston rod at the end of the frame plate 11 is on the same axis as the slide column 52. By controlling the piston rod at the end of the frame plate 11 to push the slide column 52 to move horizontally, the piston rod at the end of the hydraulic cylinder 57 is controlled to push the slide column 52 to move closer to the ratchet cylinder 2. At this time, the limiting head 55 and the hook 22 are loosened, which makes it easy to quickly remove the hook 22, reduce the labor intensity of the operators, and speed up the overall production and assembly progress.
[0046] In practical use, the ratchet cylinder 2 is placed on the surface of the roller 13 and the pushing of the clamping plate 34 is stopped. At this time, the slide bar 32 moves relative to the tension spring 33, which limits the ratchet cylinder 2 on both sides, so that the ratchet cylinder 2 remains stable during the assembly of the screw 21, thereby quickly clamping the ratchet cylinder 2.
[0047] When the ratchet cylinder 2 is placed on the surface of the roller 13, and the slide bar 32 slides on the inner wall of the column cylinder 31 under the force of the telescopic spring 33, the clamping plate 34 at the end of the slide bar 32 clamps and fixes both sides of the ratchet cylinder 2. When the slide bar 32 moves, it drives the tooth block 35 to move horizontally in the slide groove. The piston rod at the end of the electric piston rod 36 drives the toothed plate 37 to move in the vertical direction, so that the toothed plate 37 and the toothed block 35 are locked and limited. During the assembly process of the ratchet cylinder 2 and the screw 21, the ratchet cylinder 2 can always remain fixed, and the ratchet cylinder 2 is prevented from rotating simultaneously due to the rotational friction of the screw 21, thereby improving the assembly efficiency of the ratchet cylinder 2 and the screw 21.
[0048] When assembling the screw 21, the end of the screw 21 is placed inside the circular rail 45, and the electric cylinder 47 is controlled to drive the limiting plate 48 to move relative to clamp the end of the screw 21. After clamping, the moving trolley 46 is controlled to drive the electric cylinder 47 to rotate, so that the screw 21 clamped at the end of the limiting plate 48 rotates coaxially. During the rotation of the limiting plate 48, the output shaft of the motor 41 is controlled to drive the main gear 42 to rotate. When the main gear 42 rotates, the auxiliary gear rods 43 provided on both sides of its bottom mesh and rotate. When the auxiliary gear rods 43 rotate, they drive the moving block 44 to move horizontally. The moving block 44 drives the circular rail 45 to move closer to the ratchet cylinder 2, thereby realizing automatic assembly of the screw 21 and reducing the labor intensity of the operators.
[0049] The output of the control motor 41 drives the main gear 42 to rotate. When the main gear 42 rotates, it drives the auxiliary gear rod 43 to mesh and rotate. The moving block 44 on the surface of the auxiliary gear rod 43 moves relative to each other. Since the bottom of the moving block 44 is provided with a circular rail 45, the relative movement of the circular rail 45 simultaneously controls the electric cylinder 47 to drive the limiting plate 48 to move relative to each other until the end is in contact. During the movement of the moving block 44, the limiting plate 48 pushes the ratchet cylinder 2 placed on the surface of the roller 13, so that the ratchet cylinder 2 is at the center of the roller 13. The assembly assembly 4 drives the screws 21 on both sides to be assembled simultaneously, which improves the assembly efficiency of the screws 21.
[0050] When the screw 21 end is clamped by the limiting plate 48, the hook 22 is fastened inside the limiting head 55. As the screw 21 moves the hook 22, the hook 22 applies a force to the limiting head 55. Since the screw 21 rotates and drives the hook 22 to rotate, the limiting head 55 is subjected to forces in different directions. The end of the limiting head 55 rotates on the inner wall of the rotating frame 53 under the force. Since the screw 21 moves towards the center of the ratchet cylinder 2 during the assembly process, the limiting head 55 is pulled by the tension force and pulls the slide column 52. The slide column 52 moves at the end of the base plate 51. At the same time, the slide column 52 compresses the compression spring 56 during the movement. When the screw 21 and the ratchet cylinder 2 are assembled, the hook 22 is removed from the end of the limiting head 55, and the assembled tensioner is removed from the surface of the roller 13, thereby preventing the hook 22 from swinging during the assembly of the tensioner and avoiding safety hazards.
