Description

Technical Field

[0001] The embodiments of this utility model relate to the field of machining equipment technology, specifically to a bolt pulling device based on a bolt pulling machine. Background Technology

[0002] A bolt pulling machine generally refers to a type of mechanical equipment used to quickly and accurately pull fasteners such as bolts and screws from workpieces. A bolt pulling device is specifically designed based on bolt pulling machine technology to provide torque and precise control for pulling out bolts. This device can often be used in conjunction with other tools or automated systems in factories, repair shops, and other locations to simplify operation and improve work efficiency.

[0003] According to a public notice, a bolt drawing machine (CN 221966422U) for bolt production includes a base box, the top of which is fixedly connected to an outer shell by bolts, the top of which is fixedly connected to a top box by screws, transmission boxes being fixedly connected to both sides of the outer shell by screws, rollers being installed inside the outer shell, and three circumferentially distributed receiving columns being fixedly connected to the inner wall of the outer shell by screws.

[0004] In the aforementioned application, the cooperation between the base box and the transmission box assembly makes it difficult to remove the bolts after they have been worked, resulting in the need for manual removal and reduced work efficiency. Therefore, we propose a bolt removal device based on a bolt removal machine. Utility Model Content

[0005] To overcome the above-mentioned defects, embodiments of this utility model provide a bolt pulling device based on a bolt pulling machine, which solves the problem of bolts not being able to be pulled out in related technologies.

[0006] According to one aspect, at least one embodiment of the present invention provides a bolt pulling device based on a pulling machine, including a pulling platform, a bolt placement table fixedly connected to the top of the pulling platform, a cylinder provided on the top of the bolt placement table, a control panel provided on the top of the bolt placement table, and a pulling mechanism provided on the top of the pulling platform.

[0007] The material pulling mechanism includes a motor, the side of which is fixedly connected to the inside of the material pulling platform. A threaded rod is fixedly connected to the output end of the motor. A threaded sleeve is threadedly connected to the circumferential surface of the threaded rod. A movable platform is fixedly connected to the top of the threaded sleeve. A hydraulic cylinder is fixedly connected to the side of the movable platform. One end of the hydraulic cylinder is slidably connected to a force-bearing rod via a piston. The other end of the hydraulic cylinder is slidably connected to a hydraulic rod via another piston. A clamping arc plate is fixedly connected to the end of the hydraulic rod away from the side of the hydraulic cylinder.

[0008] For example, in at least one embodiment of the present invention, a bolt pulling device based on a pulling machine is provided, which further includes: a compression spring fixedly connected to the inner wall of the clamping arc plate, and a soft pad fixedly connected to the end of the compression spring away from the inner wall of the clamping arc plate, the purpose of which is to prevent damage to the surface of the bolt during pulling.

[0009] A return spring is fixedly connected to the side of the hydraulic cylinder. The end of the return spring away from the side of the hydraulic cylinder is fixedly connected to the circumferential surface of the force-bearing rod. The purpose of this is to ensure that the force-bearing rod can automatically reset and reduce manual intervention.

[0010] A limiting shaft is fixedly connected to the side of the motor. The circumferential surface of the limiting shaft passes through and is slidably connected to the side of the threaded sleeve. The purpose of this is to prevent the threaded sleeve from rotating during movement.

[0011] The number of compression springs and soft pads is set to six, in pairs, and symmetrical to each other along the numerical central axis of the material pulling platform. The purpose is to provide comprehensive protection for the clamped bolts.

[0012] According to another aspect, at least one embodiment of the present invention also provides a bolt pulling device based on a bolt pulling machine, including a feeding mechanism. The feeding mechanism includes a rotating shaft, one end of which is rotatably connected to the top of a pulling platform. A force-bearing plate is fixedly connected to the circumferential surface of the rotating shaft, and a push plate is fixedly connected to the circumferential surface of the rotating shaft. A sliding groove is provided on the top of the pulling platform, and a rack is slidably connected inside the sliding groove. A control shaft is rotatably connected to the top of the pulling platform, and a gear is fixedly passed through the circumferential surface of the control shaft. A conveying inclined plate is fixedly connected to the circumferential surface of the control shaft. The purpose is to automatically feed the pulled bolts and reduce manual operation.

[0013] For example, in at least one embodiment of the present invention, a bolt pulling device based on a pulling machine is provided, which further includes: a torsion spring fixedly connected to the top of the pulling platform, and the end of the torsion spring away from the top of the pulling platform being fixedly connected to the circumferential surface of the rotating shaft, the purpose of which is to ensure that the rotating shaft can automatically reset and reduce manual intervention.

[0014] A support plate is fixedly connected to the top of the material pulling platform, and a compression spring is fixedly connected to the side of the support plate. The end of the compression spring away from the side of the support plate is fixedly connected to the side of the rack. The purpose is to ensure that the rack, which is not under force, can automatically reset and reduce manual intervention.

[0015] A fixing plate is fixedly connected to the top of the material pulling platform, a pusher cone is fixedly connected to the side of the fixing plate, and a collection box is fixedly connected to the side of the material pulling platform. The purpose of this is to push the clamped bolts to release them from the fixing.

[0016] The side of the force plate is located on the displacement trajectory of the moving table, and the rack is located on the displacement trajectory of the push plate. The side of the rack meshes with the circumferential surface of the gear. The purpose is to ensure that the moving table can push the force plate during the bolt removal process, and the force plate pushes the rack, causing the gear to rotate.

[0017] The beneficial effects of the embodiments of this utility model are as follows:

[0018] 1. In this utility model, through the cooperation between the motor, moving table and clamping arc plate of the material pulling mechanism, after the bolt is processed, the operator starts the motor to rotate forward through the control panel, so that the moving table moves and the force rod contacts the bolt. The clamping arc plate clamps the bolt stably through the compression spring and soft pad. Then the motor is started to rotate in reverse, and the threaded rod drives the threaded sleeve to move in the opposite direction, so that the moving table moves and drives the bolt to be pulled out. This design achieves the effect of pulling out the bolt and ensures that the bolt will not slip or be damaged by excessive force during the pulling process.

[0019] 2. In this utility model, through the cooperation of components such as the rack, conveying sloping plate, and pushing cone of the feeding mechanism, the moving table pushes the force plate during the process of pulling out the bolt. The force plate, under the force, drives the push plate to rotate through the rotating shaft. During the rotation of the push plate, it pushes the rack, which moves inside the slide groove under the force. Through the meshing of the rack and gear, the control shaft rotates, driving the conveying sloping plate to rotate. At this time, the bolt being pulled out is pushed by the pushing cone, causing the bolt to leave one end of the force rod, thus releasing the bolt from fixation. The bolt is then conveyed into the collection box through the conveying sloping plate. This design achieves the effect of automatically unloading the pulled-out bolt, reducing manual operation and improving work efficiency. Attached Figure Description

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it.

[0028] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0029] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] like Figures 1-5 As shown, it illustrates a bolt pulling device based on a pulling machine in one embodiment of the present invention, including a pulling platform 1, a bolt placement table 2 fixedly connected to the top of the pulling platform 1, a cylinder 3 provided on the top of the bolt placement table 2, a control panel 4 provided on the top of the bolt placement table 2, and a pulling mechanism 5 provided on the top of the pulling platform 1.

[0034] The material pulling mechanism 5 includes a motor 51, which is fixedly connected to the side of the material pulling platform 1. A threaded rod 52 is fixedly connected to the output end of the motor 51. A threaded sleeve 53 is threadedly connected to the circumferential surface of the threaded rod 52. A movable table 54 is fixedly connected to the top of the threaded sleeve 53. A hydraulic cylinder 55 is fixedly connected to the side of the movable table 54. A force-bearing rod 56 is slidably connected to one end of the hydraulic cylinder 55 through a piston. A hydraulic rod 57 is slidably connected to the other end of the hydraulic cylinder 55 through another piston. A clamping arc plate 58 is fixedly connected to the end of the hydraulic rod 57 away from the side of the hydraulic cylinder 55.

[0035] In some examples, a compression spring 59 is fixedly connected to the inner wall of the clamping arc plate 58, and a soft pad 510 is fixedly connected to the end of the compression spring 59 away from the inner wall of the clamping arc plate 58, the purpose of which is to prevent damage to the surface of the bolts during material removal.

[0036] A return spring 511 is fixedly connected to the side of the hydraulic cylinder 55. The end of the return spring 511 away from the side of the hydraulic cylinder 55 is fixedly connected to the circumferential surface of the force rod 56. The purpose is to ensure that the force rod 56 can automatically reset and reduce manual intervention.

[0037] A limiting shaft 512 is fixedly connected to the side of the motor 51. The circumferential surface of the limiting shaft 512 passes through and slides through the side of the threaded sleeve 53. The purpose of this is to prevent the threaded sleeve 53 from rotating during movement.

[0038] The number of compression springs 59 and soft pads 510 is set to six, in pairs, and symmetrical to each other along the numerical central axis of the material pulling platform 1. The purpose is to provide comprehensive protection for the clamped bolts.

[0039] For example, such as Figures 1-5 As shown, after the bolt processing is completed, the operator starts the motor 51 to rotate forward via the control panel 4. The output end of the motor 51 rotates, which drives the threaded rod 52 to rotate. The rotation of the threaded rod 52 causes the threaded sleeve 53 to move linearly through the limiting shaft 512. The movement of the threaded sleeve 53 drives the moving table 54 to move. During the movement of the moving table 54, the force rod 56 contacts the bolt and is forced to retract into the hydraulic cylinder 55. At this time, the hydraulic rod 57 extends outward under the pressure of the liquid inside the hydraulic cylinder 55. The movement of the hydraulic rod 57 drives the clamping arc plate 58 to move. The clamping arc plate 58 stably clamps the bolt through the compression spring 59 and the soft pad 510. Then, the motor 51 is started to rotate in reverse, and the threaded rod 52 drives the threaded sleeve 53 to move in the opposite direction, causing the moving table 54 to move and pull out the bolt.

[0040] like Figures 1-5 As shown, this invention illustrates a bolt pulling device based on a bolt pulling machine in another embodiment of the present invention. It is largely the same as the technical solution described above, so only the differences are emphasized. The device includes a feeding mechanism 6, which comprises a rotating shaft 61. One end of the rotating shaft 61 is rotatably connected to the top of the pulling platform 1. A force-bearing plate 62 is fixedly connected to the circumferential surface of the rotating shaft 61, and a push plate 63 is fixedly connected to the circumferential surface of the rotating shaft 61. A sliding groove 64 is provided on the top of the pulling platform 1, and a rack 65 is slidably connected inside the sliding groove 64. A control shaft 66 is rotatably connected to the top of the pulling platform 1, and a gear 67 is fixedly passed through the circumferential surface of the control shaft 66. A conveying inclined plate 68 is fixedly connected to the circumferential surface of the control shaft 66. The purpose of this device is to automatically feed the pulled bolts, reducing manual operation.

[0041] In some examples, a torsion spring 69 is fixedly connected to the top of the material pulling platform 1. The end of the torsion spring 69 away from the top of the material pulling platform 1 is fixedly connected to the circumferential surface of the rotating shaft 61. The purpose of this is to ensure that the rotating shaft 61 can automatically reset and reduce manual intervention.

[0042] A support plate 610 is fixedly connected to the top of the material pulling platform 1. A compression spring 611 is fixedly connected to the side of the support plate 610. The end of the compression spring 611 away from the side of the support plate 610 is fixedly connected to the side of the rack 65. The purpose is to ensure that the rack 65, which is not under force, can automatically reset and reduce manual intervention.

[0043] A fixing plate 612 is fixedly connected to the top of the material pulling platform 1, a pusher cone 613 is fixedly connected to the side of the fixing plate 612, and a collection box 614 is fixedly connected to the side of the material pulling platform 1. The purpose of this is to push the clamped bolts to release the fixation.

[0044] The side of the force plate 62 is located on the displacement trajectory of the moving table 54, and the rack 65 is located on the displacement trajectory of the push plate 63. The side of the rack 65 meshes with the circumferential surface of the gear 67. The purpose is to ensure that the moving table 54 can push the force plate 62 during the bolt removal process. The force plate 62 is subjected to force to push the rack 65, causing the gear 67 to rotate.

[0045] For example, such as Figures 1-5 As shown, during the process of the moving table 54 pulling out the bolt, it pushes the force plate 62. The force plate 62, under the force, drives the push plate 63 to rotate through the rotating shaft 61. During the rotation of the push plate 63, it pushes the rack 65. The rack 65, under the force, moves inside the slide groove 64. Through the meshing of the rack 65 and the gear 67, the rack 65 moves and drives the gear 67 to rotate. The rotation of the gear 67 drives the control shaft 66 to rotate. The rotation of the control shaft 66 drives the conveying inclined plate 68 to rotate. At this time, the bolt being pulled out is pushed by the pusher cone 613, causing the bolt to leave one end of the force rod 56, releasing the bolt from fixation. The bolt is then conveyed into the collection box 614 through the conveying inclined plate 68.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
