This method is labor-intensive, inefficient, and the shaping effect is greatly affected by the worker's skill level and experience, making it difficult to guarantee consistent shaping quality. Some methods use simple molds for shaping, but the mold structure is relatively simple and cannot effectively shape tube ends of different specifications and degrees of deformation, resulting in poor adaptability.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0023] Please see Figures 1-5 This utility model discloses a bicycle frame tube end shaping device, including an operating platform 1 and a control console 2 disposed on one side of the operating platform 1, and also including a tube end shaping component 3, an auxiliary telescopic component 4, and a clamping component 5, wherein:

[0024] An operating box 11 is fixed to the operating console 1 by bolts, and the control console 2 is located on the electrical control box 21 and is electrically connected to it;

[0025] Please refer to the appendix. Figure 3 The tube shaping assembly 3 includes a central shaft 31. One end of the central shaft 31 is fixed to the inner wall of the operating box 11 by screws, and the other end is provided with a number of grooves 311 along the circumferential direction. A tension spring 32 is welded inside the grooves 311. One end of the tension spring 32 is connected to a ring 33. The ring 33 is hinged to the bottom of the shaping block 34. Specifically, when the force of outward expansion of the shaping block 34 decreases, under the rebound of the tension spring 32, the tension spring 32 pulls the shaping block 34 inward through the ring 33, thereby realizing the automatic expansion and contraction action.

[0026] Please refer to the appendix. Figure 4 The auxiliary telescopic component 4 includes a slide cylinder 41, a lead screw 42, a driven gear 43, a linkage gear 44, a straight shaft 45, and a servo motor 46. The slide cylinder 41 is a flat-topped cone shape, with one smaller end fitted into one end of the shaping block 34. Both ends of the slide cylinder 41 are fitted into the inner wall of the operating box 11 and slide together.

[0027] One end of the shaping block 34 is nested on the outside of the central shaft 31 along the circumferential direction. Several limiting rods 35 are welded to the central shaft 31 along the circular axis direction. The limiting rods 35 pass through the shaping block 34 and slide in fit. Specifically, the limiting rods 35 can limit the movement of the shaping block 34, so that the displacement trajectory generated by the force on one end of the shaping block 34 is the same as that of the other end.

[0028] The slide cylinder 41 is slidably fitted through the central shaft 31. The two ends of the slide cylinder 41 are fitted with lead screws 42 and rotate in a spiral manner. One end of the lead screw 42 passes through one side of the operating box 11 and is welded with a driven gear 43. The driven gears 43 are symmetrically arranged and mesh with the linkage gears 44.

[0029] The linkage gear 44 is welded to the middle of the straight shaft 45. One end of the straight shaft 45 is connected to one end of the servo motor 46 through a coupling. The servo motor 46 is electrically connected to the control box 21. Specifically, the control console 2 executes commands through the control box 21 to control the action of the servo motor 46.

[0030] In this embodiment, the servo motor 46 drives the linear shaft 45 to rotate, which in turn drives the linkage gear 44 to rotate. The linkage gear 44 uses the driven gear 43 to drive the lead screws 42 on both sides to rotate synchronously, and then interacts with both sides of the slide cylinder 41. Through the helical force, the slide cylinder 41 is driven to slide forward on the central shaft 31, and the shaping block 34 that is pressed against the outside is expanded outward under the limit of the limiting rod 35, thereby shaping the frame tube opening and restoring it to its deformed roundness. Example 2

[0031] Based on the above embodiment 1, please refer to the appendix. Figure 5 The clamping assembly 5 includes a clamping plate 51, which has an arc-shaped structure. A latex pad 511 is attached to the inner side of the clamping plate 51. Specifically, the arc-shaped clamping plate 51 can fit more closely to the wall of the frame tube, resulting in a more secure clamping. The latex pad 511 can adapt to changes in the curvature of frame tubes with different diameters, thereby strengthening the clamping.

[0032] The clamping plate 51 is symmetrically arranged on one side of the control box 11, with the outer side welded to the top of the slide rod 52. The bottom end of the slide rod 52 is fitted into the control table 1 and slides together.

[0033] The slide bar 52 is fitted into both ends of the bidirectional spiral shaft 53 and rotates in a spiral manner. The bidirectional spiral shaft 53 has a secondary bevel gear 54 in the middle, which meshes with the main bevel gear 55. The main bevel gear 55 is welded to one end of the motor 56.

[0034] In this embodiment, the motor 56 can drive the main bevel gear 55 to rotate. The main bevel gear 55 drives the double spiral shaft 53 to rotate through the secondary bevel gear 54, which in turn acts spirally on the slide rods 52 that are fitted at both ends, causing the slide rods 52 to move in opposite directions. The slide rods 52 drive the clamping plate 51 to clamp the frame tube.

[0035] The working principle and usage process of this utility model: When using the device, first input the inner diameter of the bicycle frame tube using the screen of the control console 2, place the end to be repaired on the outside of the shaping block 34, and then start the device. The control console 2 uses the electrical control box 2 to control the servo motor 46 to start. The servo motor 46 drives the straight shaft 45 to rotate, which in turn drives the linkage gear 44 to rotate. The linkage gear 44 uses the driven gear 43 to drive the lead screws 42 on both sides to rotate synchronously, which in turn interacts with both sides of the slide cylinder 41. Through the helical force, the slide cylinder 41 is driven to slide forward on the central shaft 31.

[0036] Since the slide cylinder 41 is a flat-topped cone shape, when the slide cylinder 41 slides forward, it will squeeze the outer abutting shaping block 34 and expand outward under the limit of the limiting rod 35 until one end of the shaping block 34 abuts the frame tube and suspends it in the air and fixes it. Then the motor 56 is started. The motor 56 drives the main bevel gear 55 to rotate. The main bevel gear 55 drives the double spiral shaft 53 to rotate through the secondary bevel gear 54. Then the spiral acts on the slide rod 52 that is fitted at both ends, causing the slide rod 52 to move towards each other. The slide rod 52 drives the clamping plate 51 to clamp the frame tube.

[0037] Subsequently, the control console 2 controls the servo motor 46 to continue rotating, causing the outer side of the shaping block 34 to expand to the input inner diameter of the frame tube, and performs intermittent forward and reverse rotation of the servo motor 46 until the deformation at the point where the frame tube and the shaping block 34 meet is restored to normal. Then, the frame tube is removed, rotated at a certain angle, and the above operation is repeated until the deformation of the frame tube opening is restored. This device can shape the opening of frame tubes with different inner diameters, and has strong applicability and high efficiency.
