[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. After the whole bundle of flywheel discs is transported to the feeding mechanism, the whole bundle of flywheel discs is driven to move in the gap on the bottom frame in sequence through the cooperation among the bottom frame, the transport block, the first protrusion, and the flywheel disc, until it moves between the two clamping blocks; and the whole bundle of flywheel discs with different thicknesses and outer diameters is fixed through the cooperation among the clamping block, the baffle, the driving block, the slider, and the second protrusion, without specifying the height or outer diameter of the whole bundle of flywheel discs, so as to make up for the casting error of the flywheel discs and meet the feeding requirements of the whole bundle of flywheel discs with different thicknesses and outer diameters; 2. Through the cooperation among the lever, chassis, flywheel disc, punching machine, auxiliary tooling, driving block and clamping block, a single flywheel disc is pushed onto the slider of the punching machine in turn, and then the slide slides on the fixed seat to drive the flywheel disc to move to the punching area, and the three-axis punching mechanism is used to punch holes on the single flywheel disc, thereby improving the quality of the processed flywheel disc. At the same time, there is no need for workers to place the flywheel discs one by one on the auxiliary tooling, which further improves the efficiency of producing fitness bikes and reduces the danger of workers' operation process; 3. Through the cooperation among the first motor, the driving rod, the baffle, the connecting rod, the lever, the arc block and the flywheel disc, the flywheel disc slides on the chassis and falls on the auxiliary tooling on one side, and the three-axis punching mechanism is used to drill holes on a single flywheel disc, thereby improving the quality of the processed flywheel disc. At the same time, there is no need for workers to place the flywheel discs one by one on the auxiliary tooling, thereby further improving the efficiency of producing fitness bikes and reducing the danger of workers' operation process; In addition, by cooperating among the adjusting block, the adjusting slot, the connecting rod, the first column and the driving rod, the moving range of the arc block on the baffle is changed, so that the lever can push the flywheel discs of different outer diameters to the auxiliary tooling, and there is no need to separately set driving rods of different lengths, thereby reducing the cost required for manufacturing the feeding mechanism; in addition, by cooperating among the screw rod, the limit plate, the adjusting block, the nut and the driving rod, the sliding of the adjusting block in the adjusting slot is restricted, so that the adjusting block with the adjusted position is fixed, and the adjustment block is prevented from moving relative to the driving rod during the movement, changing the distance from the first column to the fixed end of the driving rod, resulting in a change in the moving range of the arc block, and being unable to effectively push the top flywheel disc to the slide, thereby ensuring the normal feeding of the feeding mechanism and improving the efficiency of producing flywheel discs; 4. Through the cooperation among the second motor, the first driving wheel, the baffle, the limit block, the first column, the sleeve, the third column and the second column, the sleeve is driven to rotate on the baffle, so that several levers on the sleeve contact the flywheel disc at the top in turn, driving the flywheel disc at the top to fall onto the slider on the side, and cooperating with the three-axis punching mechanism to drill holes on a single flywheel disc, thereby improving the quality of the flywheel disc after processing.

Through the cooperation among the fourth motor, the half cam, the chassis, the second limit groove, the half gear, the fourth gear, the second connecting block, the third gear and the transport block, the transport block is driven to rotate around the connecting end of the second connecting block and the chassis and parallel to the chassis, thereby driving the whole bundle of flywheel discs on the chassis to move horizontally, so as to realize the feeding of the whole bundle of flywheel discs. At the same time, a plurality of rollers provided on the chassis are in contact with the flywheel discs, so as to reduce the friction between the flywheel disc and the chassis, so that the flywheel disc can move better on the chassis, thereby improving the feeding efficiency of the flywheel disc; In addition, since the number of teeth and the module of the half gear are consistent with those of the third gear, one rotation of the half gear will drive the third gear to rotate one circle, so that after the transport block drives the flywheel to move once, it will pause for a certain period of time and load the flywheel at the end one by one without the need for programming control, thereby reducing the difficulty of programming and control of the overall system; at the same time, through the cooperation between the half cam and the second limit groove, the fourth gear is restricted from rotating on the chassis, thereby preventing the transport block from being rotated on the chassis by external force, driving the flywheel to move, and affecting the normal loading of the flywheel, thereby improving the efficiency of producing outdoor fitness bikes.

[0034] The present invention provides a punching device for outdoor fitness bike production, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes a punching machine 2 and a feeding mechanism 3 used in conjunction 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 slide 7 slidably arranged on the fixed seat 6, the slide 7 is symmetrically slidably connected with fixed blocks 8, and two fixed blocks 8 are respectively in contact with two sides of the flywheel disc 1. After the flywheel disc 1 is placed on the slide 7, the two fixed blocks 8 are closed toward the inside to achieve the fixation of the flywheel disc 1 on the slide 7, and the slide 7 slides on the fixed seat 6 to drive the flywheel disc 1 to move to the punching area, and cooperates with the three-axis punching mechanism 4 to punch holes on a single flywheel disc 1, thereby improving the quality of the flywheel disc 1 after processing. Specifically, a motor is provided on the fixed seat 6, and a screw is provided on the movable end of the motor to be rotatably connected to the fixed seat 6. The screw is threadedly connected to the slide 7, and the screw is driven to rotate by the motor, and the slide 7 is driven to slide on the fixed seat 6, thereby moving the flywheel disc 1 to the punching area; The feeding mechanism 3 includes a base frame 11 and a baffle 12 arranged on the base frame 11, a transport block 13 is rotatably connected to the base frame 11, and a plurality of first protrusions 14 are arranged on the top of the transport block 13 to contact the flywheel disc 1 in sequence. Fig.16 As shown, by rotating the transport block 13 on the base frame 11, when the transport block 13 rotates clockwise from the left side to the right side, the first protrusion 14 provided on the transport block 13 is higher than the top end of the base frame 11, and contacts the whole bundle of flywheel discs 1 on the base frame 11 through the first protrusion 14, and the component force generated drives the whole bundle of flywheel discs 1 to move on the base frame 11. Then, when the transport block 13 rotates counterclockwise from the left side to the right side, the first protrusion 14 on the transport block 13 retracts to the bottom of the base frame 11 to avoid the first protrusion 14 contacting the whole bundle of flywheel discs 1 and driving it to move in the opposite direction, and finally the transport block 13 returns to the starting point. In addition, since the spacing between adjacent first protrusions 14 is equal to the spacing between adjacent whole bundles of flywheel discs 1, after repeating the above actions, the transport block 13 will sequentially drive the whole bundle of flywheel discs 1 to move in the gap on the base frame 11 until it moves between the two clamping blocks 16; The baffle plate 12 is symmetrically connected with a slider 15 along the vertical sliding connection, and the slider 15 is connected with a clamping block 16 along the longitudinal sliding connection, the clamping block 16 contacts the side surface of the flywheel disc 1, and the end of the clamping block 16 is provided with a second protrusion 17, the baffle plate 12 and the second protrusion 17 are respectively in contact with the upper and lower sides of the flywheel disc 1, and the two clamping blocks 16 slide inward on the baffle plate 12 so that the side surface of the clamping block 16 contacts the whole bundle of flywheel discs 1, and then the slider 15 is driven to slide upward by the driving block 18, driving the clamping block 16 slidingly arranged on the slider 15 to move together, until the second protrusion 17 provided at the end of the clamping block 16 contacts the whole bundle of flywheel discs 1, driving the whole bundle of flywheel discs 1 to move upward until its upper end surface contacts the baffle plate 12, thereby fixing the whole bundle of flywheel discs 1 of 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 of different thicknesses and outer diameters; The invention also includes a driving block 18 and a lever 19 for driving the slider 15 and the flywheel disc 1 to move on the baffle 12 respectively. The lever 19 contacts the side of the flywheel disc 1, and drives the flywheel disc 1 to move on the base frame 11 through the lever 19, so that it falls on the auxiliary tooling 5 of the punching machine 2 on one side, and cooperates with the driving block 18 to drive the clamping block 16 to move up, so that the next flywheel disc 1 moves to one side of the lever 19, and repeats the above actions many times, and pushes a single flywheel disc 1 onto the slide 7 in turn, and then slides on the fixed seat 6 through the slide 7 to drive the flywheel disc 1 to move to the punching area, and cooperates with the three-axis punching mechanism 4 to punch holes on 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 efficiency of producing fitness bikes and reducing the danger of workers' operation process.

Then, the nut 29 is further rotated so that friction is generated between the adjusting block 25 and the driving rod 22, limiting the sliding of the adjusting block 25 in the adjusting groove 24, thereby fixing the adjusting block 25 with the adjusted position, avoiding the adjustment block 25 from moving relative to the driving rod 22 during the movement, changing the distance from the first column 26 to the fixed end of the driving rod 22, causing the moving range of the arc block 20 to change, and failing to effectively push the flywheel disc 1 on the top to the slide 7, thereby ensuring the normal feeding of the feeding mechanism 3 and improving the efficiency of producing the flywheel disc 1.

[0044] Example 1 The present invention provides a punching device for outdoor fitness bike production, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, after the whole bundle of flywheel discs 1 is transported to the feeding mechanism 3 by conveying with a conveyor belt or manually, as shown in FIG. Fig.16 As shown, by rotating the transport block 13 on the base frame 11, when the transport block 13 rotates from the left side to the right side in a clockwise direction, the first protrusion 14 provided on the transport block 13 is higher than the top end of the base frame 11, and contacts the whole bundle of flywheel discs 1 on the base frame 11 through the first protrusion 14, and the component force generated drives the whole bundle of flywheel discs 1 to move on the base frame 11. Then, when the transport block 13 rotates from the right side to the left side in a counterclockwise direction, the first protrusion 14 on the transport block 13 retracts to the bottom of the base frame 11 to avoid the first protrusion 14 contacting the whole bundle of flywheel discs 1 and driving it to move in the opposite direction, and finally the transport block 13 returns to the starting point. In addition, since the spacing between adjacent first protrusions 14 is equal to the spacing between adjacent whole bundles of flywheel discs 1, after repeating the above actions, the transport block 13 will sequentially drive the whole bundle of flywheel discs 1 to move in the gap on the base frame 11 until it moves between the two clamping blocks 16; The two clamping blocks 16 slide inward on the baffle 12, so that the side of the clamping blocks 16 contacts the whole bundle of flywheel discs 1, and then the driving block 18 drives the slider 15 to slide upward, driving the clamping blocks 16 slidably arranged on the slider 15 to move together, until the second protrusion 17 provided at the end of the clamping block 16 contacts the whole bundle of flywheel discs 1, driving the whole bundle of flywheel discs 1 to move upward until the upper end surface thereof contacts the baffle 12, thereby fixing the whole bundle of flywheel discs 1 of different thicknesses and outer diameters; Then, the lever 19 moves in the gap on the base frame 11, contacts the flywheel disc 1 on the top in turn, and pushes the flywheel disc 1 on the top to move through the thrust generated after the contact, so that it falls into the slide 7 on one side, and then the driving block 18 drives the clamping block 16 to move up, so that the next flywheel disc 1 moves to the side of the lever 19, and the above actions are repeated many times, and the single flywheel disc 1 is pushed onto the slide 7 of the punching machine 2 in turn, and then the two fixing blocks 8 are closed toward the inside to fix the flywheel disc 1 on the slide 7, and the slide 7 slides on the fixing seat 6, driving the flywheel disc 1 to move to the punching area, and cooperates with the three-axis punching mechanism 4 to punch holes on the single flywheel disc 1, thereby improving the quality of the flywheel disc 1 after processing, and 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 efficiency of producing fitness bikes and reducing the danger of workers' operation process.

[0045] Example 2 On the basis of Example 1, Figure 5 and Figure 6As shown, the driving rod 22 is driven to rotate on the baffle 12 by the first motor 21. Since the two ends of the connecting rod 23 are respectively connected to the lever 19 and the driving rod 22 for rotation, the torque generated is transmitted to the lever 19 through the connecting rod 23, and the lever 19 is driven to move back and forth on the baffle 12, so that the arc block 20 provided at the end of the lever 19 contacts the side of the flywheel disc 1, and the flywheel disc 1 is driven to slide on the bottom frame 11, so that it falls on the auxiliary tooling 5 on one side, and the three-axis punching mechanism 4 is cooperated to punch holes on 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 on the auxiliary tooling 5 one by one, which further improves the efficiency of producing fitness bikes and reduces the danger of workers' operation process. 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 then changing the range of movement of the arc block 20 on the baffle 12, so that the lever 19 can push the flywheel disc 1 of different outer diameters to the auxiliary tooling 5, and at the same time, there is no need to separately set driving rods 22 of different lengths, thereby reducing the cost required for manufacturing the feeding mechanism 3; after the screw rod 28 passes through the limit plate 27, the screw rod 28 is rotated so that one end of the screw rod 28 is fixed on the adjusting block 25, and then the nut 29 is rotated on the screw rod 28, so that One side of the adjusting block 25 and the nut 29 are in contact with the driving rod 22 and the limit plate 27 respectively, and then the nut 29 is further rotated to generate friction between the adjusting block 25 and the driving rod 22, limiting the sliding of the adjusting block 25 in the adjusting groove 24, thereby fixing the adjusting block 25 with the adjusted position to prevent the adjusting block 25 from moving relative to the driving rod 22 during movement, changing the distance from the first column 26 to the fixed end of the driving rod 22, causing the moving range of the arc block 20 to change, and failing to effectively push the top flywheel disc 1 onto the slide 7, thereby ensuring the normal feeding of the feeding mechanism 3 and improving the efficiency of producing the flywheel disc 1.

[0046] Example 3 On the basis of Example 1, Figure 7 , Figure 8 and Fig. 9As shown, the first driving wheel 33 is driven to rotate on the baffle 12 by the second motor 32, so that the arc-shaped limit block 35 provided on one side of the first driving wheel 33 slides out from between the plurality of first columns 26, and the restriction on the rotation of the sleeve 30 on the baffle 12 is released. Then the third columns 34 provided on the other side of the first driving wheel 33 contact the second columns 31 respectively. The force generated after the contact between the two drives the sleeve 30 to rotate on the baffle 12, so that the plurality of levers 19 on the sleeve 30 contact the flywheel disc 1 on the top in turn, driving the flywheel disc 1 on the top to fall onto the auxiliary tooling 5 on one side, and cooperate with the three-axis punching mechanism 4 to punch holes on 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 on the auxiliary tooling 5 one by one, further improving the efficiency of producing fitness bikes and reducing the danger of workers' operation process. Then, the first driving wheel 33 continues to rotate, so that the limit block 35 re-enters between the plurality of first columns 26, and contacts the side surfaces of the plurality of first columns 26 through both sides of the limit block 35 at the same time. The generated resistance limits the sleeve 30 from rotating on the baffle 12, thereby preventing the previous flywheel disc 1 from falling to the auxiliary tooling 5. When the next flywheel disc 1 moves up, the lever 19 moves next and moves above the next flywheel disc 1, preventing the next flywheel disc 1 from moving up normally, thereby ensuring the normal feeding of the next flywheel disc 1 and improving the efficiency of producing fitness bikes.

[0047] Example 4 On the basis of Example 1, Figure 4 , Fig.10 , Fig.11 and Fig.12As shown, the first gear 43 is driven to rotate on the baffle 12 by the third motor 42, and the second driving wheel 39 is driven to rotate on the baffle 12 by the transmission torque of the second gear 44, so that the limiting wheel 40 provided on one side of the second driving wheel 39 slides out of the first limiting groove 37, and the restriction on the driving block 18 sliding on the baffle 12 is released. Then the shifting block 41 provided on the other side of the second driving wheel 39 contacts the shifting 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 with the driving block 18 and the slider 15, the slider 15 is driven to slide vertically on the baffle 12, and the fourth columns 49 provided on both sides of the clamping block 16 contact the slide groove 48, driving the clamping block 16 to slide upward together, and the whole bundle of flywheel discs 1 is moved up one The end distance makes the top flywheel disc 1 located on one side of the shifting block 41, thereby realizing single-sheet feeding of the flywheel disc 1 and improving the efficiency of producing outdoor fitness bikes; after the flywheel disc 1 is moved up 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 contact each other limits the driving block 18 from sliding on the baffle 12, thereby 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, thereby ensuring the normal feeding of the feeding mechanism 3 and improving the efficiency of producing fitness bikes; at the same time, the pause gap can cooperate with the shifting rod 19 to move the top flywheel disc 1 to the feeding mechanism 3, without the need to set up additional programming for control, reducing the difficulty of programming control of the overall feeding mechanism 3 and improving the efficiency of producing fitness bikes; In addition, when it is necessary to fix the entire bundle of flywheel discs 1 on the baffle 12, first drive the slider 15 to slide down, and through the cooperation of the fourth column 49 and the slide groove 48, drive the clamping block 16 to move down until the first inclined surface 45 provided at the end of the second protrusion 17 contacts the flywheel disc 1. The force generated after the contact pushes the clamping block 16 to move inward, so that the fourth column 49 slides in the slide groove 48 and contacts 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 protrusion 17 completely passes through the entire 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 on the baffle 12 The clamping block 16 is then moved upward to push the clamping block 16 to move inward, so that the upper end surface of the second protrusion 17 contacts the lower side of the entire bundle of flywheel discs 1, and then the clamping block 16 is moved upward to drive the entire bundle of flywheel discs 1 to move upward until the upper side surface of the flywheel disc 1 contacts the baffle 12, thereby achieving the fixation of the entire bundle of flywheel discs 1, and cooperating with the shifting block 41 to realize the loading of a single flywheel disc 1, so that it falls onto the auxiliary tooling 5 on one side, and cooperating with the three-axis punching mechanism 4 to punch holes in 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 efficiency of producing fitness bikes and reducing the danger of workers' operation.

[0048] Example 5 On the basis of Example 1, Fig.13 , Fig.14 and Fig.15 As shown, the fourth motor 54 drives the half gear 55 and the half cam 58 to rotate on the base frame 11, so that the half cam 58 slides out of the second limiting groove 57, and the restriction on the rotation of the fourth gear 53 on the base frame 11 is released. At the same time, the half gear 55 is meshed with the fourth gear 53, and the force generated by the contact between the two drives the fourth gear 53 to rotate on the base frame 11. Since the third gear 52 provided on one side of one of the second connecting blocks 50 is meshed with the fourth gear 53, one of the second connecting blocks 50 is driven to rotate on the base frame 11. A parallelogram is formed between the transport block 13, the plurality of second connecting blocks 50 and the base frame 11, which drives the transport block 13 to rotate around the connecting end of the second connecting block 50 and the base frame 11 and to be parallel to the base frame 11, thereby driving the entire bundle of flywheel discs 1 on the base frame 11 to move horizontally, thereby realizing the feeding of the entire bundle of flywheel discs 1. At the same time, the plurality of rollers 51 provided on the base frame 11 contact with the flywheel disc 1, thereby reducing the friction between the flywheel disc 1 and the base frame 11, so that the flywheel disc 1 can move better on the base frame 11, thereby improving the feeding efficiency of the flywheel disc 1. In addition, since the number of teeth and the module of the half gear 55 and the third gear 52 are consistent, after the half gear 55 rotates one circle, it just drives the third gear 52 to rotate one circle, so that the transport block 13 drives the flywheel disc 1 to move once, and then pauses for a certain period of time, and the flywheel disc 1 at the end is fed one by one, without the need for programming control, thereby reducing the difficulty of programming control of the overall system; at the same time, during the pause, the half cam 58 re-enters the second limit groove 57, and through the force generated by the contact between the two, the fourth gear 53 is limited to rotate on the base frame 11, thereby preventing the transport block 13 from being rotated on the base frame 11 by an external force, driving the flywheel disc 1 to move, affecting the normal feeding of the flywheel disc 1, and thus improving the efficiency of producing outdoor fitness bikes; In addition, when the two first protrusions 14 at the end move to the bottom of the flywheel disc 1, the conveying block 13 is then rotated on the base frame 11, so that the second inclined surface 60 provided on one side of the vertical block 59 contacts the flywheel disc 1, and the generated force drives the vertical block 59 to slide on the first protrusion 14, and compresses the return spring 62 between the vertical block 59 and the second protrusion 17, so that the flywheel disc 1 can smoothly enter between the two vertical blocks 59, and the rebound force generated by the compression of the return spring 62 drives one side of the vertical block 59 to contact the flywheel disc 1, and exerts a certain force to align the flywheel discs 1 with each other, thereby fixing the flywheel disc 1 on the base frame 11, realizing the preliminary positioning of the flywheel disc 1, and facilitating the subsequent fixing of the entire bundle of flywheel discs 1 on the baffle 12, thereby improving the feeding efficiency of the flywheel disc 1.
