Description

Technical Field

[0001] The present invention relates to the technical field of punching devices, and particularly to a punching device for the production of outdoor fitness bikes. Background Art

[0002] An outdoor fitness bike is a fitness instrument belonging to aerobic fitness equipment. It mainly simulates the movement mode of outdoor bicycle riding. The user sits on the seat and pedals the pedals with both feet to make the wheel (flywheel disc) rotate. At the same time, a chain or belt is used to connect the pedals and the flywheel disc to achieve power transmission.

[0003] During the production process of the flywheel disc, it needs to go through processes such as casting, punching, machining, and grinding in sequence. After casting, the stack of flywheel discs needs to be cleaned and dried to remove the residual casting materials on the surface of the flywheel disc, such as molding sand, coating, metal chips, etc. Then, several flywheel discs are stacked together uniformly to facilitate the transportation of the flywheel discs to the next process. However, subsequent punching cannot be directly performed on several flywheel discs together. They need to be separated one by one. Currently, they are generally separated manually, and then the single flywheel disc is placed on the punching machine, resulting in low efficiency and certain safety hazards.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. After transporting the whole bundle of flywheel discs to the feeding mechanism, through the cooperation among the chassis, the handling block, the first bump, and the flywheel disc, the whole bundle of flywheel discs is driven to move intermittently on the chassis in sequence until it moves between the two clamping blocks; and through the cooperation among the clamping block, the baffle, the driving block, the slider, and the second bump, the whole bundle of flywheel discs with different thicknesses and outer diameters is fixed, without specifying the height or outer diameter of the whole bundle of flywheel discs, compensating for the casting error of the flywheel disc, and meeting the feeding requirements of the whole bundle of flywheel discs with different thicknesses and outer diameters;

[0018] 2. Through the cooperation among the dial rod, the chassis, the flywheel disc, the punching machine, the auxiliary tooling, the driving block, and the clamping block, the single flywheel disc is pushed onto the slider of the punching machine in sequence, and then the flywheel disc is driven to move to the punching area by the sliding of the sliding table on the fixed seat, and the single flywheel disc is punched in cooperation with the three-axis punching mechanism, thereby improving the quality of the processed flywheel disc. At the same time, it is not necessary for workers to place the flywheel discs on the auxiliary tooling one by one, further improving the production efficiency of the fitness bike and reducing the danger in the operation process of workers;

[0019] 3. Through the cooperation among the first motor, the driving rod, the baffle, the connecting rod, the dial rod, the arc-shaped block, and the flywheel disc, the flywheel disc slides on the chassis and falls onto the auxiliary tooling on one side, and the single flywheel disc is drilled in cooperation with the three-axis punching mechanism, improving the quality of the processed flywheel disc. At the same time, it is not necessary for workers to place the flywheel discs on the auxiliary tooling one by one, further improving the production efficiency of the fitness bike and reducing the danger in the operation process of workers;

[0020] In addition, by adjusting the cooperation among the adjusting block, adjusting groove, connecting rod, first column, and driving rod, the moving range of the arc-shaped block on the baffle is changed, enabling the dial rod to push flywheel discs with different outer diameters onto the auxiliary fixture. Meanwhile, there is no need to separately set driving rods with different lengths, reducing the cost required for manufacturing the loading mechanism. Moreover, through the cooperation among the screw, limit plate, adjusting block, nut, and driving rod, the sliding of the adjusting block in the adjusting groove is restricted, thereby fixing the adjusted position of the adjusting block, preventing the adjusting block from moving relative to the driving rod during movement and changing the distance from the first column to the fixed end of the driving rod, which may cause the moving range of the arc-shaped block to change and fail to effectively push the flywheel disc at the top onto the sliding table, thus ensuring the normal feeding of the loading mechanism and improving the efficiency of manufacturing flywheel discs.

[0021] 4. Through the cooperation among the second motor, first driving wheel, baffle, limit block, first column, sleeve, third column, and second column, the sleeve is driven to rotate on the baffle, causing several dial rods on the sleeve to sequentially contact the flywheel disc at the top, driving the flywheel disc at the top to fall onto the adjacent slider, and cooperating with the three-axis drilling mechanism to drill a single flywheel disc, improving the quality of the processed flywheel disc. Meanwhile, there is no need for workers to place the flywheel discs one by one on the auxiliary fixture, further improving the efficiency of manufacturing fitness bikes and reducing the danger during the operation of workers.

[0022] Subsequently, through the cooperation among the first driving wheel, limit block, and first column, the rotation of the sleeve on the baffle is restricted, preventing the next flywheel disc from being blocked when the previous flywheel disc falls onto the auxiliary fixture and the next flywheel disc moves upward, and the dial rod then moves to the upper side of the next flywheel disc, thus ensuring the normal feeding of the next flywheel disc and improving the efficiency of manufacturing fitness bikes.

[0023] 5. Through the cooperation among the third motor, first gear, baffle, second gear, second driving wheel, limit wheel, first limit groove, driving block, dial block, dial groove, first connecting block, and slider, the slider is driven to slide vertically on the baffle, and through the cooperation among the clamping block, fourth column, chute, flywheel disc, and dial block, single-piece loading of the flywheel disc is achieved, improving the efficiency of manufacturing outdoor fitness bikes. After the flywheel disc is moved upward once, through the cooperation among the second driving wheel, limit wheel, and first limit groove, the sliding of the driving block on the baffle is restricted, preventing the clamping block from moving up and down on the baffle under the action of external force and affecting the stability of fixing the flywheel disc, thus ensuring the normal loading of the loading mechanism and improving the efficiency of manufacturing fitness bikes. At the same time, during the pause interval, the flywheel disc at the top can be moved onto the loading mechanism in cooperation with the dial rod, without the need to separately set programming for control, reducing the difficulty of programming control of the overall loading mechanism and improving the efficiency of manufacturing fitness bikes, thereby improving the efficiency of manufacturing outdoor fitness bikes.

[0024] 6. Through the cooperation among the fourth motor, the semi-cam, the chassis, the second limiting groove, the semi-gear, the fourth gear, the second connecting block, the third gear, and the handling block, the handling block will be driven to rotate around the connecting end of the second connecting block and the chassis and be parallel to the chassis, thereby driving the whole bundle of flywheel disks on the chassis to move horizontally, realizing the feeding of the whole bundle of flywheel disks. At the same time, several rollers provided on the chassis are in contact with the flywheel disks, reducing the friction between the flywheel disks and the chassis, enabling the flywheel disks to move better on the chassis and improving the feeding efficiency of the flywheel disks.

[0025] In addition, since the number of teeth and the module of the semi-gear and the third gear are the same, after the semi-gear rotates one circle, it just drives the third gear to rotate one circle. After the handling block drives the flywheel disk to move once, it pauses for a certain period of time to perform single-piece feeding on the flywheel disk at the end, without the need for programming control, reducing the difficulty of programming control of the overall system. At the same time, through the cooperation between the semi-cam and the second limiting groove, the rotation of the fourth gear on the chassis is restricted, thereby preventing the handling block from rotating on the chassis under the action of external force and driving the flywheel disk to move, affecting the normal feeding of the flywheel disk, and thus improving the production efficiency of outdoor fitness bikes.

[0049] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by this application.

[0050] The present invention provides a punching device for the production of outdoor fitness bikes, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, which includes a punching machine 2 and a feeding mechanism 3 used in cooperation with a flywheel disc 1. The punching machine 2 includes a three-axis punching mechanism 4 and an auxiliary tooling 5. The auxiliary tooling 5 includes a fixed seat 6 and a sliding table 7 slidably arranged on the fixed seat 6. The sliding table 7 is symmetrically and slidably connected with fixing blocks 8. The two fixing blocks 8 are respectively in contact with both sides of the flywheel disc 1. After the flywheel disc 1 is placed on the sliding table 7, the two fixing blocks 8 are closed inward to fix the flywheel disc 1 on the sliding table 7. The sliding table 7 slides on the fixed seat 6, driving the flywheel disc 1 to move to the punching area, and cooperating with the three-axis punching mechanism 4 to punch a single flywheel disc 1, thereby improving the quality of the processed flywheel disc 1. Specifically, a motor is provided on the fixed seat 6, and a screw rod rotatably connected to the fixed seat 6 is provided at the movable end of the motor. The screw rod is threadedly connected to the sliding table 7. By driving the screw rod to rotate by the motor, the sliding table 7 is driven to slide on the fixed seat 6, thereby moving the flywheel disc 1 to the punching area;

[0051] The feeding mechanism 3 includes a bottom frame 11 and a baffle 12 arranged on the bottom frame 11. A handling block 13 is rotatably connected to the bottom frame 11. A plurality of first convex blocks 14 are sequentially arranged on the top of the handling block 13 and are respectively in contact with the flywheel discs 1. As Figure 16 shown, by rotating the handling block 13 on the bottom frame 11, when the handling block 13 rotates from the left to the right in the clockwise direction, the first convex blocks 14 provided on the handling block 13 are higher than the top end of the bottom frame 11, and the first convex blocks 14 are in contact with the whole bundle of flywheel discs 1 on the bottom frame 11, and the generated component force drives the whole bundle of flywheel discs 1 to move on the bottom frame 11. Then, when the handling block 13 rotates from the left to the right in the counterclockwise direction, the first convex blocks 14 on the handling block 13 retract below the bottom frame 11 to avoid the first convex blocks 14 being in contact with the whole bundle of flywheel discs 1 and driving it to move in the reverse direction. Finally, the handling block 13 returns to the starting point. In addition, since the distance between adjacent first convex blocks 14 is equal to the distance between adjacent whole bundles of flywheel discs 1, after repeating the above actions, the handling block 13 will sequentially drive the whole bundle of flywheel discs 1 to move at intervals on the bottom frame 11 until it moves between two clamping blocks 16;

[0052] Symmetrically arranged on the baffle 12 are sliders 15 which are slidably connected vertically. Longitudinally slidably connected to the sliders 15 are clamping blocks 16. The clamping blocks 16 are in contact with the side surface of the flywheel disc 1. At the end of the clamping block 16 is provided a second convex block 17. The baffle 12 and the second convex block 17 are respectively in contact with the upper and lower sides of the flywheel disc 1. By sliding the two clamping blocks 16 inward on the baffle 12, the side surface of the clamping block 16 is in contact with the whole bundle of flywheel discs 1. Subsequently, the driving block 18 drives the slider 15 to slide upward, driving the clamping block 16 slidably arranged on the slider 15 to move together until the second convex block 17 provided at the end of the clamping block 16 is in contact with the whole bundle of flywheel discs 1, driving the whole bundle of flywheel discs 1 to move upward until its upper end surface is in contact with the baffle 12, thereby fixing the whole bundle of flywheel discs 1 with different thicknesses and outer diameters, without specifying the height or outer diameter of the whole bundle of flywheel discs 1, compensating for the casting error of the flywheel disc 1, and meeting the feeding requirements of the whole bundle of flywheel discs 1 with different thicknesses and outer diameters;

[0053] Also included are a driving block 18 and a lever 19 which respectively drive the slider 15 and the flywheel disc 1 to move on the baffle 12. The lever 19 is in contact with the side surface of the flywheel disc 1. By driving the flywheel disc 1 to move on the chassis 11 through the lever 19, it falls onto the auxiliary tooling 5 of the punching machine 2 on one side. Cooperating with the driving block 18 to drive the clamping block 16 to move upward, the next flywheel disc 1 is moved to one side of the lever 19. Repeating the above actions multiple times, the single flywheel discs 1 are successively pushed onto the sliding table 7. Then, by sliding the sliding table 7 on the fixed seat 6, the flywheel disc 1 is driven to move to the punching area, cooperating with the three-axis punching mechanism 4 to punch the single flywheel disc 1, thereby improving the quality of the processed flywheel disc 1. At the same time, there is no need for workers to place the flywheel discs 1 on the auxiliary tooling 5 one by one, further improving the production efficiency of the fitness bike and reducing the danger in the operation process of workers.

[0054] Preferably, as Figure 3 and Figure 5As shown, the lever 19 is slidably arranged on the baffle 12. An arc-shaped block 20 that contacts the flywheel disc 1 is provided at the end of the lever 19. A first motor 21 is provided on the baffle 12. A driving rod 22 is provided at the movable end of the first motor 21. A connecting rod 23 is provided between the end of the driving rod 22 and the lever 19. Both ends of the connecting rod 23 are rotatably connected to the lever 19 and the driving rod 22 respectively. The first motor 21 drives the driving rod 22 to rotate on the baffle 12. Since both ends of the connecting rod 23 are rotatably connected to the lever 19 and the driving rod 22 respectively, the generated torque is transmitted to the lever 19 through the connecting rod 23, and the lever 19 is driven to reciprocate on the baffle 12, so that the arc-shaped block 20 provided at the end of the lever 19 contacts the side surface of the flywheel disc 1, and the flywheel disc 1 is driven to slide on the chassis 11 and fall onto the auxiliary tooling 5 on one side, cooperating with the three-axis punching mechanism 4 to punch a single flywheel disc 1, thereby improving the quality of the processed flywheel disc 1. At the same time, there is no need for workers to place the flywheel discs 1 one by one on the auxiliary tooling 5, further improving the production efficiency of the fitness bike and reducing the danger during the operation of workers.

[0055] Preferably, as Figure 5 and Figure 6 shown, an adjustment groove 24 is provided on the driving rod 22. An adjustment block 25 is slidably connected in the adjustment groove 24. A first upright column 26 that is rotatably connected to the adjustment block 25 is provided at the end of the connecting rod 23. By sliding the adjustment block 25 in the adjustment groove 24, the first upright column 26 provided at the end of the connecting rod 23 is driven to slide on the driving rod 22, thereby changing the distance from the first upright column 26 to the fixed end of the driving rod 22, and further changing the moving range of the arc-shaped block 20 on the baffle 12, so that the lever 19 can push flywheel discs 1 with different outer diameters onto the auxiliary tooling 5. At the same time, there is no need to separately set driving rods 22 with different lengths, reducing the cost required for manufacturing the feeding mechanism 3; A limiting plate 27 is slidably connected to one side of the driving rod 22. A screw rod 28 that is rotatably connected to the adjustment block 25 is provided on the limiting plate 27. A nut 29 that contacts the limiting plate 27 is threadedly connected to the end of the screw rod 28. After passing the screw rod 28 through the limiting plate 27, the screw rod 28 is rotated so that one end of the screw rod 28 is fixed on the adjustment block 25, and then the nut 29 is rotated on the screw rod 28 so that one side of the adjustment block 25 and the nut 29 respectively contact the driving rod 22 and the limiting plate 27. Then the nut 29 is further rotated so that a frictional force is generated between the adjustment block 25 and the driving rod 22, restricting the adjustment block 25 from sliding in the adjustment groove 24, thereby fixing the adjustment block 25 with the adjusted position, avoiding the adjustment block 25 moving relative to the driving rod 22 during the movement process, changing the distance from the first upright column 26 to the fixed end of the driving rod 22, resulting in a change in the moving range of the arc-shaped block 20 and being unable to effectively push the flywheel disc 1 at the top onto the sliding table 7, and further ensuring the normal feeding of the feeding mechanism 3 and improving the production efficiency of the flywheel disc 1.

[0056] Preferably, as Figure 7 , Figure 8 and Figure 9 shown, there are several lever rods 19, which are respectively arranged on the sleeves 30 rotatably connected to the baffle 12. By rotating the sleeves 30 on the baffle 12, several lever rods 19 are driven to contact the flywheel disc 1 at the top in sequence, driving the flywheel disc 1 at the top to fall onto the sliding table 7 beside, and cooperating with the three-axis punching mechanism 4 to punch a single flywheel disc 1, so as to improve the quality of the flywheel disc 1 after processing. At the same time, there is no need for workers to place the flywheel discs 1 one by one on the auxiliary tooling 5, further improving the production efficiency of the fitness bike and reducing the danger in the operation process of workers; several second columns 31 are provided at the end of the sleeve 30, and a second motor 32 is provided on the baffle 12 to provide power for the first driving wheel 33 to rotate on the baffle 12; a first driving wheel 33 is provided at the movable end of the second motor 32, and several third columns 34 are provided on one side of the first driving wheel 33. The several third columns 34 are respectively in contact with the second columns 31 and drive the sleeve 30 to rotate on the baffle 12, cooperating with the lever rod 19 to contact the flywheel disc 1 at the top, realizing the single-piece feeding of the flywheel disc 1, improving the quality of the flywheel disc 1 after processing. At the same time, there is no need for workers to place the flywheel discs 1 one by one on the auxiliary tooling 5, further improving the production efficiency of the fitness bike and reducing the danger in the operation process of workers; an arc-shaped limiting block 35 is provided on the other side of the first driving wheel 33. The two sides of the limiting block 35 are respectively in contact with the several third columns 34 and limit the rotation of the sleeve 30 on the baffle 12, avoiding that when the previous flywheel disc 1 falls to the auxiliary tooling 5 and the next flywheel disc 1 moves up, the lever rod 19 then moves and moves above the next flywheel disc 1, blocking the normal upward movement of the next flywheel disc 1, and thus ensuring the normal feeding of the next flywheel disc 1 and improving the production efficiency of the fitness bike.

[0057] Preferably, as Figure 10 and Figure 11As shown, a first connecting block 36 is provided between the driving block 18 and the slider 15. Two ends of the first connecting block 36 are respectively rotatably connected to the driving block 18 and the slider 15. By sliding the driving block 18 on the baffle 12, one end of the first connecting block 36 is driven to move together. Since two ends of the first connecting block 36 are respectively rotatably connected to the driving block 18 and the slider 15, the slider 15 is driven to slide vertically on the baffle 12. A plurality of first limiting grooves 37 are provided on the driving block 18, and a dial groove 38 is provided between two adjacent first limiting grooves 37. A second driving wheel 39 is rotatably connected to the baffle 12. A limiting wheel 40 and a dial block 41 are respectively provided on two sides of the second driving wheel 39. The limiting wheel 40 is in contact with the first limiting groove 37 and limits the driving block 18 to slide on the baffle 12, preventing the clamping block 16 from moving up and down on the baffle 12 under the action of external force, affecting the stability of fixing the flywheel disc 1, and further ensuring the normal feeding of the feeding mechanism 3 and improving the production efficiency of the fitness bike. At the same time, the pause gap can cooperate with the dial rod 19 to move the top flywheel disc 1 onto the feeding mechanism 3, without the need to additionally set programming for control, reducing the programming control difficulty of the overall feeding mechanism 3 and improving the production efficiency of the fitness bike. The dial block 41 is in contact with the dial groove 38 and drives the driving block 18 to slide on the baffle 12, driving the clamping block 16 to move on the baffle 12, moving the whole bundle of flywheel discs 1 upward by a certain distance, so that the top flywheel disc 1 is located on one side of the dial block 41, and further realizing the single-piece feeding of the flywheel disc 1 and improving the production efficiency of the outdoor fitness bike. It further includes a third motor 42 provided on the baffle 12 and a first gear 43 provided on the movable end of the third motor 42. A second gear 44 meshing with the first gear 43 is provided at the end of the second driving wheel 39, providing power for the second driving wheel 39 to rotate on the baffle 12. At the same time, it is driven to rotate by the third motor 42, better controlling the rotation frequency of the second driving wheel 39, improving the overall feeding stability, and further improving the production efficiency of the fitness bike.

[0058] Preferably, as Figure 4 、 Figure 10 and Figure 12As shown, the end of the second bump 17 is provided with a first inclined surface 45 that contacts the flywheel disc 1, enabling the clamping block 16 to pass through the flywheel disc 1 smoothly. A clamping block 46 is slidably connected to the baffle 12. One side of the clamping block 46 contacts the clamping block 16. A clamping spring 47 is provided between the clamping block 46 and the baffle 12. The resilience generated after the compression of the clamping spring 47 drives the clamping block 16 to reset, realizing the fixation of the whole bundle of flywheel discs 1. Cooperating with the dial block 41 to achieve the feeding of a single flywheel disc 1, and cooperating with the three-axis punching mechanism 4 to punch the single flywheel disc 1, thereby improving the quality of the flywheel disc 1 after processing. At the same time, there is no need for workers to place the flywheel discs 1 on the auxiliary tooling 5 one by one, further improving the production efficiency of the fitness bike and reducing the danger in the operation process of workers. In addition, the clamping block 46 is arranged between the clamping block 16 and the clamping spring 47 to prevent the clamping block 16 from directly contacting the clamping spring 47 during the downward movement. After the two come into contact, a downward frictional force is generated to drive one end of the clamping spring 47 to move, resulting in the clamping spring 47 deviating from the specified position and affecting the clamping of the flywheel disc 1 by the clamping block 16, thus ensuring the normal feeding of the feeding mechanism 3 and improving the production efficiency of the fitness bike. A chute 48 is provided horizontally on one side of the slider 15. Fourth columns 49 that are slidably connected to the chute 48 are respectively provided on both sides of the clamping block 16. When the slider 15 slides on the baffle 12, the fourth columns 49 provided on both sides of the clamping block 16 contact the chute 48, driving the clamping block 16 to slide upward together. At the same time, when the clamping block 16 moves on the baffle 12, the fourth columns 49 slide in the chute 48, preventing interference between the clamping block 16 and the slider 15.

[0059] Preferably, as Figure 13 shown, a plurality of second connecting blocks 50 are rotatably connected to the handling block 13. The end of the second connecting block 50 is rotatably connected to the chassis 11. A parallelogram is formed among the handling block 13, the plurality of second connecting blocks 50, and the chassis 11. Thus, when one of the second connecting blocks 50 rotates on the chassis 11, it will drive the handling block 13 to rotate around the connection end of the second connecting block 50 and the chassis 11 and be parallel to the chassis 11, thereby driving the whole bundle of flywheel discs 1 on the chassis 11 to move horizontally and realizing the feeding of the whole bundle of flywheel discs 1. A plurality of rollers 51 that contact the flywheel disc 1 are provided on the chassis 11, reducing the frictional force between the flywheel disc 1 and the chassis 11, enabling the flywheel disc 1 to move better on the chassis 11, and improving the feeding efficiency of the flywheel disc 1.

[0060] Preferably, as Figure 14 and Figure 15As shown, a third gear 52 is provided on one side of one of the second connecting blocks 50. A fourth gear 53 meshing with the third gear 52 is rotatably connected to the chassis 11. It further includes a fourth motor 54 provided on the chassis 11. A half gear 55 meshing with the fourth gear 53 is provided at the movable end of the fourth motor 54. Specifically, the number of teeth and the module of the half gear 55 and the third gear 52 are the same, so that after the half gear 55 rotates one circle, it just drives the third gear 52 to rotate one circle, so that after the handling block 13 drives the flywheel disc 1 to move once, it pauses for a certain time to perform single-piece feeding on the flywheel disc 1 at the end, without the need for programming control, reducing the difficulty of programming control of the overall system; a driven wheel 56 is provided on one side of the fourth gear 53, and a second limiting groove 57 is provided on one side of the driven wheel 56. A half cam 58 in contact with the second limiting groove 57 is provided on one side of the half gear 55 to limit the rotation of the fourth gear 53 on the chassis 11. Thus, after the whole bundle of flywheel discs 1 at the end is moved to the end, it pauses for a certain time for single-piece feeding, and at the same time, it avoids the handling block 13 being rotated on the chassis 11 by an external force and driving the flywheel disc 1 to move, affecting the normal feeding of the flywheel disc 1, thereby improving the production efficiency of outdoor fitness bikes.

[0061] Preferably, as Figure 13 shown, a vertical block 59 is slidably connected to the two first convex blocks 14 at the end to preliminarily position the flywheel disc 1, facilitating the subsequent fixing of the whole bundle of flywheel discs 1 on the baffle 12 and improving the feeding efficiency of the flywheel disc 1; second inclined surfaces 60 in contact with the flywheel disc 1 are respectively provided on one side of the two vertical blocks 59, so that the flywheel disc 1 can smoothly pass through the vertical block 59 and enter between the two vertical blocks 59; a guide rod 61 slidably connected to the first convex block 14 is provided on one side of the vertical block 59, and a return spring 62 is provided between the vertical block 59 and the first convex block 14 to apply a force to the vertical block 59 to achieve the alignment of the flywheel disc 1; the return spring 62 is sleeved outside the guide rod 61 to prevent the return spring 62 from falling off the designated position, thereby ensuring the stability of the overall structure, better realizing the preliminary positioning of the flywheel disc 1, and improving the feeding efficiency of the flywheel disc 1.

[0062] Preferably, as Figure 1 and Figure 2 shown, a double-headed cylinder 9 is provided on the sliding table 7. The two movable ends of the double-headed cylinder 9 are respectively connected to the fixed block 8 to provide power for the movement of the fixed block 8 on the sliding table 7, realizing the clamping of the flywheel disc 1 on the sliding table 7, avoiding the flywheel disc 1 falling off the sliding sleeve during the processing and moving processes, thereby improving the production efficiency of fitness bikes; a working platform 10 is provided on the double-headed cylinder 9 for placing the flywheel disc 1, and there are a number of holes for the drill bit to pass through the flywheel disc 1.

[0063] Embodiment 1

[0064] The present invention provides a punching device for the production of outdoor fitness bikes, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown. After the whole bundle of flywheel disks 1 is transported to the feeding mechanism 3 by conveyor belt or manually carried, as Figure 16 shown, by rotating the handling block 13 on the chassis 11, when the handling block 13 rotates from the left side to the right side in the clockwise direction, the first convex block 14 provided on the handling block 13 is higher than the top end of the chassis 11, and the whole bundle of flywheel disks 1 on the chassis 11 is contacted by the first convex block 14, and the generated component force drives the whole bundle of flywheel disks 1 to move on the chassis 11. Then, when the handling block 13 rotates from the right side to the left side in the counterclockwise direction, the first convex block 14 on the handling block 13 retracts below the chassis 11 to avoid the first convex block 14 contacting the whole bundle of flywheel disks 1 and driving it to move in the reverse direction. Finally, the handling block 13 returns to the starting point. In addition, since the distance between adjacent first convex blocks 14 is equal to the distance between adjacent whole bundles of flywheel disks 1, after repeating the above actions, the handling block 13 will sequentially drive the whole bundle of flywheel disks 1 to move at intervals on the chassis 11 until it moves between the two clamping blocks 16;

[0065] By sliding the two clamping blocks 16 inward on the baffle 12, the side surface of the clamping block 16 is contacted with the whole bundle of flywheel disks 1. Subsequently, the driving block 18 drives the slider 15 to slide upward, driving the clamping block 16 slidably arranged on the slider 15 to move together until the second convex block 17 provided at the end of the clamping block 16 contacts the whole bundle of flywheel disks 1, driving the whole bundle of flywheel disks 1 to move upward until its upper end surface contacts the baffle 12, realizing the fixation of the whole bundle of flywheel disks 1 with different thicknesses and outer diameters;

[0066] Then, the dial rod 19 moves at intervals on the chassis 11, sequentially contacts the flywheel disks 1 at the top, and pushes the flywheel disks 1 at the top to move by the thrust generated after the contact, so that they fall into the slide table 7 on one side. Then, the driving block 18 drives the clamping block 16 to move upward, so that the next flywheel disk 1 moves to one side of the dial rod 19. Repeat the above actions multiple times to sequentially push the single flywheel disks 1 onto the slide table 7 of the punching machine 2. Subsequently, the two fixing blocks 8 are closed inward to realize the fixation of the flywheel disks 1 on the slide table 7. The slide table 7 slides on the fixed seat 6, driving the flywheel disks 1 to move to the punching area, and cooperating with the three-axis punching mechanism 4 to punch the single flywheel disks 1, thereby improving the quality of the flywheel disks 1 after processing. At the same time, there is no need for workers to place the flywheel disks 1 one by one on the auxiliary tooling 5, further improving the production efficiency of the fitness bike and reducing the danger in the operation process of workers.

[0067] Embodiment 2

[0068] On the basis of Embodiment 1, as Figure 5 and Figure 6As shown in the figure, the driving rod 22 is driven by the first motor 21 to rotate on the baffle 12. Since the two ends of the connecting rod 23 are respectively rotationally connected to the lever 19 and the driving rod 22, the generated torque is transmitted to the lever 19 through the connecting rod 23, and the lever 19 is driven to reciprocate on the baffle 12, so that the arc-shaped block 20 provided at the end of the lever 19 contacts the side surface of the flywheel disc 1, and the flywheel disc 1 is driven to slide on the chassis 11 and fall onto the auxiliary tooling 5 on one side, cooperating with the three-axis punching mechanism 4 to punch a single flywheel disc 1, thereby improving the quality of the flywheel disc 1 after processing. At the same time, there is no need for workers to place the flywheel discs 1 one by one on the auxiliary tooling 5, further improving the production efficiency of the fitness bike and reducing the danger during the operation of workers;

[0069] In addition, by sliding the adjusting block 25 in the adjusting groove 24, the first column 26 provided at the end of the connecting rod 23 is driven to slide on the driving rod 22, thereby changing the distance from the first column 26 to the fixed end of the driving rod 22, and further changing the moving range of the arc-shaped block 20 on the baffle 12, so that the lever 19 can push the flywheel discs 1 with different outer diameters onto the auxiliary tooling 5. At the same time, there is no need to separately set driving rods 22 with different lengths, reducing the cost required for manufacturing the feeding mechanism 3; After passing the screw rod 28 through the limiting plate 27, rotate the screw rod 28 so that one end of the screw rod 28 is fixed on the adjusting block 25, and then rotate the nut 29 on the screw rod 28 so that one side of the adjusting block 25 and the nut 29 respectively contact the driving rod 22 and the limiting plate 27, and then further rotate the nut 29 so that a frictional force is generated between the adjusting block 25 and the driving rod 22, restricting the sliding of the adjusting block 25 in the adjusting groove 24, thereby fixing the adjusting block 25 with the adjusted position, avoiding the relative movement of the adjusting block 25 and the driving rod 22 during the movement process, changing the distance from the first column 26 to the fixed end of the driving rod 22, resulting in a change in the moving range of the arc-shaped block 20 and being unable to effectively push the flywheel disc 1 at the top onto the sliding table 7, thus ensuring the normal feeding of the feeding mechanism 3 and improving the production efficiency of the flywheel disc 1.

[0070] Embodiment 3

[0071] On the basis of Embodiment 1, as Figure 7 、 Figure 8 and Figure 9As shown in the figure, the first driving wheel 33 is driven by the second motor 32 to rotate on the baffle 12, so that the arc-shaped limiting block 35 provided on one side of the first driving wheel 33 slides out between several first columns 26, releasing the restriction on the rotation of the sleeve 30 on the baffle 12. Then, the third columns 34 provided on the other side of the first driving wheel 33 are respectively in contact with the second columns 31, and the acting force generated after the contact between the two drives the sleeve 30 to rotate on the baffle 12, so that several lever rods 19 on the sleeve 30 are successively in contact with the flywheel disc 1 at the top, driving the flywheel disc 1 at the top to fall onto the auxiliary tooling 5 on one side, and cooperating with the three-axis punching mechanism 4 to punch a single flywheel disc 1, thereby improving the quality of the flywheel disc 1 after processing. At the same time, there is no need for workers to place the flywheel discs 1 one by one on the auxiliary tooling 5, further improving the production efficiency of the fitness bike and reducing the danger in the operation process of workers;

[0072] Subsequently, continue to rotate the first driving wheel 33 so that the limiting block 35 re-enters between several first columns 26, and the resistance generated by the two sides of the limiting block 35 being in contact with the sides of several first columns 26 at the same time restricts the rotation of the sleeve 30 on the baffle 12, avoiding the situation where the previous flywheel disc 1 falls to the auxiliary tooling 5, and when the next flywheel disc 1 moves up, the lever rod 19 then moves and moves above the next flywheel disc 1, blocking the normal upward movement of the next flywheel disc 1, thereby ensuring the normal feeding of the next flywheel disc 1 and improving the production efficiency of the fitness bike.

[0073] Embodiment 4

[0074] On the basis of Embodiment 1, as Figure 4 、 Figure 10 、 Figure 11 and Figure 12As shown in the figure, the third motor 42 drives the first gear 43 to rotate on the baffle 12. The transmitted torque of the second gear 44 is used to drive the second driving wheel 39 to rotate on the baffle 12, so that the limiting wheel 40 provided on one side of the second driving wheel 39 slides out of the first limiting groove 37, releasing the restriction on the sliding of the driving block 18 on the baffle 12. Then, the dial block 41 provided on the other side of the second driving wheel 39 contacts the dial groove 38 and drives the driving block 18 to slide on the baffle 12. Since the two ends of the first connecting block 36 are respectively rotatably connected to the driving block 18 and the slider 15, the slider 15 is driven to slide vertically on the baffle 12. The fourth upright posts 49 provided on both sides of the clamping block 16 contact the sliding grooves 48, driving the clamping block 16 to slide upward together, moving the whole bundle of flywheel discs 1 upward by a certain distance, so that the flywheel disc 1 at the top is located on one side of the dial block 41, thus realizing the single-piece feeding of the flywheel disc 1 and improving the production efficiency of outdoor fitness bikes; after the flywheel disc 1 is moved upward once, the limiting wheel 40 provided on one side of the second driving wheel 39 re-enters the first limiting groove 37, and the resistance generated after the two come into contact restricts the sliding of the driving block 18 on the baffle 12, preventing the clamping block 16 from moving up and down on the baffle 12 under the action of external forces, affecting the fixing stability of the flywheel disc 1, and thus ensuring the normal feeding of the feeding mechanism 3 and improving the production efficiency of fitness bikes; at the same time, during the pause interval, the top flywheel disc 1 can be moved onto the feeding mechanism 3 by the dial rod 19, without the need to set additional programming for control, reducing the programming control difficulty of the overall feeding mechanism 3 and improving the production efficiency of fitness bikes;

[0075] In addition, when the whole bundle of flywheel discs 1 needs to be fixed on the baffle 12, first drive the slider 15 to slide downward. Through the cooperation of the fourth upright posts 49 and the sliding grooves 48, the clamping block 16 is driven to move downward until the first inclined surface 45 provided at the end of the second convex block 17 contacts the flywheel disc 1. The acting force generated after the contact pushes the clamping block 16 to move inward, causing the fourth upright posts 49 to slide in the sliding grooves 48, and contacting the clamping block 46 through one side of the clamping block 16, driving the clamping block 46 to move on the baffle 12 and compressing the clamping spring 47 until the second convex block 17 completely passes through the whole bundle of flywheel discs 1. Under the action of the spring force after the clamping spring 47 is compressed, the clamping block 46 is pushed to slide on the baffle 12, pushing the clamping block 16 to move inward, so that the upper end surface of the second convex block 17 contacts the lower side of the whole bundle of flywheel discs 1. Subsequently, by moving the clamping block 16 upward, the whole bundle of flywheel discs 1 is driven to move upward until the upper side surface of the flywheel disc 1 contacts the baffle 12, thus realizing the fixation of the whole bundle of flywheel discs 1. Cooperating with the dial block 41 to realize the single-piece feeding of the flywheel disc 1, making it fall onto the auxiliary tooling 5 on one side, and cooperating with the three-axis punching mechanism 4 to punch the single-piece flywheel disc 1, thereby improving the quality of the processed flywheel disc 1. At the same time, there is no need for workers to place the flywheel discs 1 on the auxiliary tooling 5 one by one, further improving the production efficiency of fitness bikes and reducing the danger during the operation of workers.

[0076] Embodiment 5

[0077] Based on Embodiment 1, as Figure 13 , Figure 14 and Figure 15 shown, the fourth motor 54 drives the half gear 55 and the half cam 58 to rotate on the chassis 11, so that the half cam 58 slides out of the second limiting groove 57, releasing the restriction on the rotation of the fourth gear 53 on the chassis 11. At the same time, the half gear 55 meshes with the fourth gear 53, and the acting force generated after the two come into contact drives the fourth gear 53 to rotate on the chassis 11. Since the third gear 52 provided on one side of one of the second connecting blocks 50 meshes with the fourth gear 53, one of the second connecting blocks 50 is driven to rotate on the chassis 11. Since a parallelogram is formed among the handling block 13, several second connecting blocks 50 and the chassis 11, the handling block 13 will be driven to rotate around the connecting end of the second connecting block 50 and the chassis 11 and be parallel to the chassis 11, thereby driving the whole bundle of flywheel discs 1 on the chassis 11 to move horizontally, realizing the feeding of the whole bundle of flywheel discs 1. At the same time, several rollers 51 provided on the chassis 11 are in contact with the flywheel discs 1, reducing the frictional force between the flywheel discs 1 and the chassis 11, enabling the flywheel discs 1 to move better on the chassis 11 and improving the feeding efficiency of the flywheel discs 1;

[0078] In addition, since the number of teeth and the module of the half gear 55 and the third gear 52 are the same, after the half gear 55 rotates one circle, the third gear 52 is exactly driven to rotate one circle, so that after the handling block 13 drives the flywheel disc 1 to move once, it pauses for a certain period of time to perform single-piece feeding on the flywheel disc 1 at the end, without the need for programming control, reducing the difficulty of programming control of the overall system. At the same time, during the pause process, the half cam 58 re-enters the second limiting groove 57, and through the acting force generated after the two come into contact, the rotation of the fourth gear 53 on the chassis 11 is restricted, thereby preventing the handling block 13 from rotating on the chassis 11 under the action of external force and driving the flywheel disc 1 to move, affecting the normal feeding of the flywheel disc 1, and further improving the production efficiency of outdoor fitness bikes;

[0079] In addition, when the two first bumps 14 at the end move to the lower side of the flywheel disc 1, then the handling block 13 is rotated on the chassis 11, so that the second inclined surface 60 provided on one side of the vertical block 59 is in contact with the flywheel disc 1, and the generated acting force drives the vertical block 59 to slide on the first bump 14 and compresses the return spring 62 between the vertical block 59 and the second bump 17, enabling the flywheel disc 1 to smoothly enter between the two vertical blocks 59. And through the resilience generated after the return spring 62 is compressed, the vertical block 59 is driven to be in contact with the flywheel disc 1 on one side and apply a certain acting force to align the flywheel discs 1 with each other, thereby fixing the flywheel disc 1 on the chassis 11, realizing the preliminary positioning of the flywheel disc 1, facilitating the subsequent fixing of the whole bundle of flywheel discs 1 on the baffle 12, and improving the feeding efficiency of the flywheel disc 1.
