Technical Field
[0001] This application relates to the field of bicycle frame cutting technology, specifically a bicycle frame cutting and fixing device. Background Technology
[0002] Bicycles are a green and environmentally friendly means of transportation. When a bicycle frame is damaged, it is necessary to cut the bicycle frame, remove the damaged parts, and then carry out repair work.
[0003] When cutting bicycle frames, a clamping claw is usually used to clamp and fix the vertical bar of the frame, which is usually located in the middle of the frame, so that the frame is suspended in the air. Then, a cutting tool is used to cut the damaged frame. However, because the two ends of the frame are suspended in the air, the frame vibrates continuously during the cutting process as the cutting tool vibrates, which affects the cutting effect of the frame.
[0004] Therefore, this application provides a bicycle frame cutting and fixing device to solve the above-mentioned problems. Utility Model Content
[0005] This application provides a bicycle frame cutting and fixing device, which aims to solve the problems mentioned in the background art, such as the existing frame fixing method using a clamping claw to clamp and fix the vertical bar of the frame, which is usually located in the middle of the frame. However, in this method, because the two ends of the frame are suspended, the frame vibrates continuously during the cutting process due to the vibration of the cutting tool, thus affecting the cutting effect of the frame.
[0006] To achieve the above objectives, this application provides the following technical solution: a bicycle frame cutting and fixing device, comprising a clamping device, a support rod fixedly disposed at the bottom end of the clamping device for supporting the clamping device, and a base fixedly disposed at the bottom end of the support rod for stabilizing the support rod;
[0007] For easy and stable fixation of the frame: The top of the base is equipped with a clamp for gripping the end of the frame. One side of the clamp has an adjusting member for angle adjustment, and the bottom of the adjusting member has a lifting member for height adjustment. The outside of the lifting member has a moving member for horizontal movement. By starting the second motor, the second threaded rod rotates, driving the moving block to move horizontally. The moving block drives the mounting column to move synchronously. Then, by starting the first motor, the gear rotates, and the gear and rack mesh, driving the lifting rod to move vertically. This adjusts the position of the clamp to correspond to one end of the frame. Then, through the second and third bearings, the horizontal and vertical angles of the clamp are adjusted, fixing the clamp to the end of the frame. This, in conjunction with the clamping device, maintains stability during frame cutting.
[0008] Preferably, to facilitate angle adjustment of the clamp: the adjusting component includes a connecting rod fixedly disposed on one side of the clamp for connecting the clamp; a second bearing sleeved on the end of the connecting rod away from the clamp for vertical rotation of the connecting rod; a connecting block disposed outside the second bearing for mounting the second bearing; a support column fixedly disposed at the bottom end of the connecting block for supporting the connecting block; and a third bearing sleeved on the outer wall of the support column for horizontal rotation of the support column. Through the action of the second bearing and the third bearing, the connecting rod and the support column can be adjusted vertically and horizontally respectively, thereby adjusting the clamp angle.
[0009] Preferably, for vertical installation of the adjusting member: the lifting member includes a lifting rod disposed at the bottom end of the adjusting member for vertical movement of the adjusting member. The adjusting member is fixedly installed by fixing the third bearing to the top end of the lifting rod.
[0010] Preferably, to facilitate the vertical movement of the lifting rod: the moving component includes a mounting column disposed at the bottom of the lifting rod for mounting the lifting rod, and a moving block fixedly disposed at the bottom end of the mounting column for driving the mounting column to move horizontally. The top end of the mounting column has a vertical moving groove, the inner wall of which has a through groove. The outer wall of the mounting column is provided with a lifting drive component for driving the lifting rod to move. The outer wall of the lifting rod is fixedly connected with a rack for meshing with the lifting drive component. The lifting drive component drives the rack to move vertically, thereby driving the lifting rod to move vertically.
[0011] Preferably, to facilitate the vertical movement of the rack: the lifting drive includes a gear inserted into the through slot for meshing with the rack, and a first motor fixedly mounted on one side of the gear for driving the gear to rotate. The vertical movement of the rack is achieved through the meshing of the gear and the rack.
[0012] Preferably, for horizontal adjustment of the movable component: a horizontal moving groove is provided at the top of the base for slidingly inserting the movable block. A moving drive component is provided inside the horizontal moving groove to drive the movable block to move. The moving drive component includes a second threaded rod inserted inside the movable block, a second motor fixed to the outer wall of the base for driving the second threaded rod to rotate, and a fourth bearing sleeved outside one end of the second threaded rod to limit its movement. By rotating the second threaded rod with the second motor, the movable block moves within the horizontal moving groove, thereby adjusting the horizontal direction of the mounting column.
[0013] Preferably, for easy clamping of the middle section of the frame: the clamping device includes a fixed clamping plate, a movable clamping plate disposed on one side of the fixed clamping plate for cooperating with the fixed clamping plate, and a fixing block fixedly disposed at one end of the fixed clamping plate for mounting the fixed clamping plate and the movable clamping plate. A limiting groove is formed on one side of the fixing block, and a limiting block for sliding through the limiting groove is fixedly connected to one end of the movable clamping plate. The movement of the limiting block causes the movable clamping plate to move synchronously, moving the fixed clamping plate and the movable clamping plate to both sides of the steel tube in the middle of the frame for clamping the frame. This, in conjunction with the clamping clamp, provides stable fixation of the frame and reduces shaking during frame cutting.
[0014] Preferably, to facilitate the movement of the limiting block: a first threaded rod for moving the limiting block is inserted inside the limiting block, and a first bearing for limiting the movement of the first threaded rod is sleeved on the outer wall of one end of the first threaded rod. By rotating the first threaded rod, the limiting block is driven to move within the limiting groove.
[0015] This application utilizes a design incorporating a clamping device, a clamp, an adjusting component, a lifting component, and a moving component. By activating a second motor, the second threaded rod rotates, driving the moving block to move horizontally. The moving block then moves the mounting column synchronously. Activating a first motor drives a gear to rotate, which, through the meshing of the gear and rack, drives the lifting rod to move vertically. This adjusts the position of the clamp to correspond with one end of the frame. The second and third bearings then adjust the horizontal and vertical angles of the clamp, securing it to the end of the frame. This design, in conjunction with the clamping device, ensures stability during frame cutting. Attached Figure Description

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0025] This embodiment provides a bicycle frame cutting and fixing device, such as... Figure 1-6 As shown, the fixing device includes a clamping device 1, a support rod 2 fixedly disposed at the bottom end of the clamping device 1 for supporting the clamping device 1, and a base 3 fixedly disposed at the bottom end of the support rod 2 for supporting the stability of the support rod 2.
[0026] To facilitate stable fixation of the frame: The top of the base 3 is equipped with a clamp 4 for gripping the end of the frame. An adjusting member 5 for adjusting the angle of the clamp 4 is provided on one side of the clamp 4. A lifting member 6 for adjusting the height of the clamp 4 is provided at the bottom of the adjusting member 5. A moving member 7 for horizontal movement of the lifting member 6 is provided outside the lifting member 6. By starting the second motor 92, the second threaded rod 91 is rotated, thereby driving the moving block 72 to move horizontally. The moving block 72 drives the mounting column 71 to move synchronously. Then, by starting the first motor 82, the gear 81 is rotated. Under the meshing action of the gear 81 and the rack 62, the lifting rod 61 is driven to move vertically, thereby adjusting the position of the clamp 4 to correspond to the position of one end of the frame. Then, through the second bearing 52 and the third bearing 55, the horizontal and vertical angles of the clamp 4 are adjusted, fixing the clamp 4 to the end of the frame. This works in conjunction with the clamping device 1 to maintain stability during frame cutting.
[0027] Specifically, to facilitate the angle adjustment of the clamp 4, the adjusting component 5 includes a connecting rod 51 fixedly mounted on one side of the clamp 4 for connecting the clamp 4, a second bearing 52 sleeved on the end of the connecting rod 51 away from the clamp 4 for vertical rotation of the connecting rod 51, a connecting block 53 mounted outside the second bearing 52 for mounting the second bearing 52, a support column 54 fixedly mounted at the bottom of the connecting block 53 for supporting the connecting block 53, and a third bearing 55 sleeved on the outer wall of the support column 54 for horizontal rotation of the support column 54. Through the action of the second bearing 52 and the third bearing 55, the connecting rod 51 and the support column 54 can be adjusted vertically and horizontally respectively, thereby adjusting the angle of the clamp 4. Both the second bearing 52 and the third bearing 55 are ball bearings. The connecting block 53 has a circular groove on the side facing the connecting rod 51. The outer ring of the second bearing 52 is welded to the inner wall of the circular groove. The inner ring of the second bearing 52 is welded to the contact part with the connecting rod 51. The end of the second bearing 52 away from the second bearing 52 is welded to the contact part with the clamp 4. The connecting block 53 is welded to the contact part with the support column 54. The height of the inner ring of the third bearing 55 is lower than the height of the outer ring. The inner ring of the third bearing 55 is welded to the outer wall of the support column 54. The bottom end of the outer ring of the third bearing 55 is welded to the top end of the lifting rod 61. The clamp 4 is closed by bolts. The operation method of the clamp 4 is the same as that of the existing ring clamp, which clamps and fixes the frame.
[0028] Specifically, for the vertical installation of the adjusting component 5: the lifting component 6 includes a lifting rod 61 disposed at the bottom of the adjusting component 5 for vertical movement of the adjusting component 5. The adjusting component 5 is fixedly installed by fixing the third bearing 55 to the top of the lifting rod 61.
[0029] More specifically, to facilitate the vertical movement of the lifting rod 61: the moving component 7 includes a mounting post 71 at the bottom of the lifting rod 61 for mounting the lifting rod 61, and a moving block 72 fixedly mounted at the bottom of the mounting post 71 for driving the mounting post 71 to move horizontally. The top of the mounting post 71 has a vertical moving groove, and the inner wall of the vertical moving groove has a through groove. The outer wall of the mounting post 71 is provided with a lifting drive component 8 for driving the lifting rod 61 to move. A rack 62 is fixedly connected to the outer wall of the lifting rod 61 for meshing with the lifting drive component 8. The lifting drive component 8 drives the rack 62 to move vertically, thereby driving the lifting rod 61 to move vertically. The size of the moving groove of the mounting post 71 is adapted to the size of the lifting rod 61, the rack 62 is inserted into the through groove, and the contact area between the lifting rod 61 and the rack 62 is welded.
[0030] Furthermore, to facilitate the vertical movement of the rack 62: the lifting drive component 8 includes a gear 81 inserted into a through slot for meshing with the rack 62, and a first motor 82 fixedly mounted on one side of the gear 81 for driving the gear 81 to rotate. The vertical movement of the rack 62 is achieved through the meshing of the gear 81 and the rack 62. One side of the gear 81 is welded to the output end of the first motor 82, which is electrically connected to an external power source. The rack 62 meshes with the gear 81, and the first motor 82 is fixedly mounted on the outer wall of the mounting column 71 via a bracket. The output end of the first motor 82 drives the rotation of the gear 81, thereby driving the rack 62 to move vertically. The rack 62 then drives the lifting rod 61 to move synchronously.
[0031] Specifically, for the horizontal adjustment of the movable component 7: a horizontal moving groove is provided at the top of the base 3 for sliding the movable block 72. Inside the horizontal moving groove is a moving drive component 9 for driving the movable block 72. The moving drive component 9 includes a second threaded rod 91 inserted inside the movable block 72, a second motor 92 fixed to the outer wall of the base 3 for driving the second threaded rod 91 to rotate, and a fourth bearing 93 sleeved on one end of the second threaded rod 91 to restrict its movement. By rotating the second threaded rod 91 driven by the second motor 92, the movable block 72 moves within the horizontal moving groove, thereby adjusting the horizontal direction of the mounting column 71. The dimensions of the horizontal moving groove and the moving block 72 are compatible. The vertical cross-section of both the horizontal moving groove and the moving block 72 is an inverted T-shape. The outer wall of the moving block 72 has a first threaded groove for threaded connection with the second threaded rod 91. The inner thread of the first threaded groove meshes with the outer thread of the second threaded rod 91. The second motor 92 is electrically connected to an external control power supply. The output end of the second motor 92 is fixedly connected to one end of the second threaded rod 91. The fourth bearing 93 is sleeved on the other end of the second threaded rod 91. The fourth bearing 93 is a ball bearing. The height of the outer ring of the fourth bearing 93 is greater than the height of the inner ring. The outer ring of the fourth bearing 93 is welded to the inner wall of the horizontal moving groove. The inner ring of the fourth bearing 93 is welded to the end of the second threaded rod 91, thereby restricting the second threaded rod 91 to only rotate. Under the meshing action of the threads, the moving block 72 is driven to move linearly in the horizontal moving groove.
[0032] Specifically, to facilitate clamping the middle section of the frame: the clamping device 1 includes a fixed clamping plate 11, a movable clamping plate 12 disposed on one side of the fixed clamping plate 11 for cooperating with the fixed clamping plate 11, and a fixing block 13 fixedly disposed at one end of the fixed clamping plate 11 for fixing the clamping plate 11 and the movable clamping plate 12. A limiting groove is provided on one side of the fixing block 13, and a limiting block 14 for sliding through the limiting groove is fixedly connected to one end of the movable clamping plate 12. By moving the limiting block 14, the movable clamping plate 12 is moved synchronously, so that the fixed clamping plate 11 and the movable clamping plate 12 are moved to both sides of the steel tube in the middle of the frame for clamping the frame. It cooperates with the clamping clamp 4 to stabilize and fix the frame, reducing shaking when cutting the frame. The fixed clamp 11 and the movable clamp 12 correspond in shape. The fixed clamp 11 and the movable clamp 12 are located on both sides of the steel pipe to clamp the steel pipe of the frame. The fixed clamp 11 is welded to the contact part of the fixed block 13. The fixed block 13 is welded to the top of the support rod 2. The bottom of the support rod 2 is welded to the top of the base 3. The movable clamp 12 is welded to the contact part of the limiting block 14. The limiting groove corresponds to the shape and size of the limiting block 14, so that the limiting block 14 cannot rotate in the limiting groove. The outer wall of the limiting block 14 is provided with a second threaded groove.
[0033] More specifically, to facilitate the movement of the limiting block 14: a first threaded rod 15 for moving the limiting block 14 is inserted inside the limiting block 14, and a first bearing 16 for limiting the movement of the first threaded rod 15 is sleeved on the outer wall of one end of the first threaded rod 15. By rotating the first threaded rod 15, the limiting block 14 is driven to move within the limiting groove. The threads on the inner wall of the second threaded groove mesh with the threads on the outer wall of the first threaded rod 15. The first bearing 16 is a ball bearing, and the connection method between the first bearing 16, the first threaded rod 15, and the limiting groove is the same as the connection method between the fourth bearing 93, the second threaded rod 91, and the horizontal moving groove. Thus, when the first threaded rod 15 is rotated, the limiting block 14 moves horizontally within the limiting groove under the action of the meshing threads. The limiting block 14 drives the movable clamping plate 12, causing the fixed clamping plate 11 and the movable clamping plate 12 to clamp the frame.
[0034] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
