DETAILED DESCRIPTION OF THE INVENTION

[0032] The present invention provides as Figures 1 to 8The shown lightweight and high-strength integrated forming equipment for bicycle crankshafts includes a drilling and forming device 3 arranged on the top of the chassis 1. A rotating rod 4 is provided at the bottom of the drilling and forming device 3, and a drill bit 5 for drilling and forming the bicycle crankshaft is installed at the bottom end of the rotating rod 4. The drilling and forming device 3 includes structures such as a motor and an electric cylinder, which are used to drive the drill bit 5 to move up and down and rotate through the rotating rod 4 to realize the drilling and forming operation. The drilling and forming device 3 and its working principle are both common existing technologies and will not be elaborated here.

[0033] A positioning table 2 for placing the bicycle crankshaft is provided on the chassis 1, and the positioning table 2 is correspondingly distributed with the drilling and forming device 3. During specific use, the bicycle crankshaft is placed on the positioning table 2, and the drilling and forming device 3 is used to perform the drilling and forming operation on the bicycle crankshaft. Moreover, a clamping device can also be arranged on the positioning table 2 to fix the bicycle crankshaft. The clamping device includes structures such as clamping plates and is used to fix the bicycle crankshaft. The clamping device is a common existing technology and will not be elaborated here.

[0034] Considering that when performing the drilling and forming operation using structures such as the drill bit 5, the drill bit 5 is prone to jitter due to the impact force. To improve the stability and accuracy of the drilling and forming operation, as shown in Figure 2 、 Figure 3 , a rotating sleeve 7 is rotatably connected to the outside of the rotating rod 4. A cross plate 8 is fixedly connected to the outer wall of the rotating sleeve 7. There are two cross plates 8, and the two cross plates 8 are respectively distributed on both sides of the rotating sleeve 7. It can also be set to three, etc., and adjusted according to the specific use situation. One end of the cross plate 8 far from the rotating sleeve 7 is fixedly connected to a vertical cylinder 9. A sliding rod 10 is slidably arranged inside the vertical cylinder 9, and the sliding rod 10 penetrates through the bottom end of the vertical cylinder 9. A rotating block 13 is rotatably arranged at the bottom end of the sliding rod 10, and a positioning frame 15 is fixedly connected to the bottom end of the rotating block 13.

[0035] When the drill bit 5 is driven by the rotating rod 4 to move downward, the positioning frame 15 first contacts the bicycle crankshaft. As the drill bit 5 continues to move downward, the sliding rod 10 retracts into the vertical cylinder 9; after the drilling is completed, when the drill bit 5 is driven by the rotating rod 4 to move upward and reset, the sliding rod 10 slides out of the vertical cylinder 9; the positioning frame 15, the sliding rod 10, the vertical cylinder 9, etc. form a support and stable structure to prevent the drill bit 5 from jittering, improve the service strength of the overall structure, and at the same time do not affect the upward movement of the drill bit 5.

[0036] In addition, when the positioning frame 15 abuts against the bicycle crankshaft, it can also reinforce the bicycle crankshaft, integrating drilling, anti-vibration, and reinforcement.

[0037] Refer to Figure 3 、 Figure 5As shown in the figure, a gasbag 16 is fixedly connected to the bottom end of the positioning bracket 15. The gasbag 16 is communicated with the inside of the vertical cylinder 9 by means of a communication component. The communication component includes a first gas channel 12 and a second gas channel 14. The first gas channel 12 is opened on the sliding rod 10 and is distributed along the axial length direction of the sliding rod 10. The second gas channel 14 is opened on the rotating block 13. One end of the second gas channel 14 is communicated with the first gas channel 12, and the other end of the second gas channel 14 is communicated with the gasbag 16.

[0038] A slider 11 is slidably arranged inside the vertical cylinder 9, and the first gas channel 12 penetrates through the slider 11. The sliding rod 10 is fixedly connected to the slider 11. A spring 17 is arranged inside the vertical cylinder 9. One end of the spring 17 is fixedly connected to the top end of the vertical cylinder 9, and the other end of the spring 17 is fixedly connected to the slider 11.

[0039] When the drill bit 5 is driven by the rotating rod 4 to move downward, the positioning bracket 15 first contacts the bicycle crankshaft. As the drill bit 5 continues to move downward, the sliding rod 10 retracts into the vertical cylinder 9. The slider 11 presses the gas inside the vertical cylinder 9 into the gasbag 16 through the first gas channel 12 and the second gas channel 14, so that the gasbag 16 expands and adaptively abuts against the bicycle crankshaft, playing a further strengthening effect. At the same time, it is applicable to the bicycle crankshaft with a special-shaped structure, improving the applicability of the lightweight and high-strength integrated forming equipment for the bicycle crankshaft.

[0040] Due to the structures such as the first gas channel 12 and the second gas channel 14 being provided, the supporting and stable structure is lightweight, reducing the load of the drilling and forming equipment 3.

[0041] In the present invention, by arranging structures such as the positioning bracket 15, the sliding rod 10, and the vertical cylinder 9, a supporting and stable structure is formed to prevent the drill bit 5 from shaking, improving the service strength of the overall structure. At the same time, the bicycle crankshaft can be strengthened, integrating drilling, anti-shaking, and strengthening, improving the use efficiency of the lightweight and high-strength integrated forming equipment for the bicycle crankshaft.

[0042] Refer to Figure 3 、 Figure 5 As shown in the figure, the positioning bracket 15 is in an inverted V shape. When the airbag 16 is in a contracted state, it can be retracted into the positioning bracket 15; when the drill bit 5 is driven by the rotating rod 4 to move downward, the positioning bracket 15 first contacts the bicycle crankshaft, and then the airbag 16 expands and contacts the bicycle crankshaft.

[0043] Refer to Figure 6 As shown in the figure, a fixing plate 6 is fixedly connected to the side wall of the drilling and forming equipment 3. The vertical cylinder 9 is slidably arranged on the fixing plate 6.

[0044] When the drill bit 5 is driven by the rotating rod 4 to move up and down, the vertical cylinder 9 slides on the fixing plate 6. The fixing plate 6 is arranged so that the vertical cylinder 9 and other structures can only move up and down and will not rotate around the drill bit 5.

[0045] To further improve the stability of the drill bit 5 during use, as shown in Figure 6 , Figure 7 , Figure 8 On the outer wall of the vertical cylinder 9, there is a fixed connection with an ear plate 24. A threaded hole 18 is opened on the ear plate 24. A threaded rod 19 is threadedly connected inside the threaded hole 18. One end of the threaded rod 19 close to the drill bit 5 is rotatably connected to a stabilizing frame 26. The stabilizing frame 26 is in a V shape and fits on the drill bit 5. The end of the threaded rod 19 away from the stabilizing frame 26 is fixedly connected with a rotating block 20. By rotating the rotating block 20, the threaded rod 19 is driven to move towards the drill bit 5.

[0046] Specifically, the operator rotates the rotating block 20 to drive the threaded rod 19 to move towards the drill bit 5, so that the stabilizing frame 26 fits on the drill bit 5. As shown in Figure 6 , the stabilizing frames 26 on both sides are distributed up and down in a staggered manner to form a stable structure, further improving the stability of the drill bit 5 during use.

[0047] During specific use, structures such as balls are arranged on the concave side of the stabilizing frame 26 to reduce the wear between it and the drill bit 5.

[0048] At the same time, the friction coefficient between the threaded rod 19 and the threaded hole 18 is appropriate, and the threaded rod 19 will not rotate randomly.

[0049] Since the stabilizing frame 26 is in a V shape, the stable structure is applicable to drill bits 5 of different sizes.

[0050] To ensure the stability of the position of the stabilizing frame 26, a positioning component cooperating with the threaded rod 19 is arranged on the ear plate 24. The positioning component includes a first circular groove 21, an elastic telescopic rod 22, a pressing block 23 and a second circular groove 25. The second circular groove 25 is opened at the bottom end of the ear plate 24. The first circular groove 21 is opened inside the ear plate 24. One end of the first circular groove 21 communicates with the second circular groove 25, and the other end of the first circular groove 21 communicates with the threaded hole 18. The inner diameter of the first circular groove 21 is larger than the inner diameter of the second circular groove 25. The pressing block 23 is slidably arranged inside the first circular groove 21. The elastic telescopic rod 22 is slidably arranged inside the second circular groove 25. The pressing block 23 is fixedly connected to the top end of the elastic telescopic rod 22. The bottom end of the elastic telescopic rod 22 cooperates with the rotating block 13.

[0051] During actual use, when the drill bit 5 is driven by the rotating rod 4 to move downward, the positioning frame 15 first contacts the bicycle crankshaft. As the drill bit 5 continues to move downward, the sliding rod 10 retracts into the interior of the vertical cylinder 9. The rotating block 13 contacts the bottom end of the elastic telescopic rod 22 and drives the elastic telescopic rod 22 and the pressing block 23 to move upward. The pressing block 23 presses against the threaded rod 19. Then, the elastic telescopic rod 22 contracts, and the reset elastic force of the elastic telescopic rod 22 causes the pressing block 23 to tightly abut against the threaded rod 19, limiting the threaded rod 19 to prevent it from rotating randomly, thereby ensuring the stability of the position of the stabilizing frame 26.

[0052] The present invention also discloses a control system for the integrated forming equipment of the lightweight and high-strength bicycle crankshaft, which is applied to the above-mentioned integrated forming equipment of the lightweight and high-strength bicycle crankshaft. It further includes a control panel 27, which is installed on the chassis 1. The control panel 27 is externally connected to the factory power supply and is used to control the drilling and forming equipment 3. The control system is a common existing technology and will not be elaborated here.
