[0003] In this regard, China's patent application number CN202021471245.4 discloses a bicycle rear frame correction device. This scheme mainly fixes the five-way bracket on the frame through the setting of a lifting assembly. At the same time, the correction rod is inserted into the top tube to further limit the head tube. Then, the position of the rear fork frame is observed by the correction part, and a hammer is used to knock and correct it until the end of the rear fork frame is stuck in the groove, thereby improving the correction effect of the rear fork frame.

[0004] However, in the process of implementing the technical solution in the embodiments of the present application, the inventor of the present application found that the above technology has at least the following technical problems:

[0014] In the above implementation process, the head rod is inserted into the head tube of the frame, and the horizontal cylinder pushes the slide to move inward. If the head tube is in the correct position, the head rod will smoothly enter the groove on the slide.

[0018] In the above implementation process, the deflected pry bar drives the gear to rotate, thereby driving the rack, the slide bar and the paddle to move up and down, thereby applying an upward or downward torque to the end of the rear fork.

[0019] In a specific embodiment, the rear fork correction member further includes a T-shaped slide groove, and the gear slides in the slide groove.

[0020] In the above implementation process, the T-shaped slide groove is arranged horizontally, and the rotating shaft of the gear is stuck in the slide groove, and can be pulled backward to disengage from the meshing with the rack, and then the slide rod and the paddle plate can move up and down freely so that the slot on the paddle plate can be aligned with one of the ends of the rear fork, and then the gear slides forward to mesh with the rack and moves downward or upward along the T-shaped slide groove, thereby preventing the gear from disengaging from the rack when force is applied.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0029] See also Figure 1-Figure 4The present application provides a bicycle frame production correction platform, including a base plate 10, on which a middle tube fixing part 20, a head tube correction part 30 and a rear fork correction part 40 are arranged, and the rear fork correction part 40 includes a scale 41 and a rotating rod 42, both of which are rotatably connected to the base plate 10, and a pry bar 43 and a dial plate 44 are movably arranged on the rotating rod 42, and the pry bar 43 is movably connected to the dial plate 44, and a card slot adapted to the rear fork of the frame is opened on the dial plate 44. Among them, after the middle tube fixing part 20 fixes the frame, the head tube part of the frame is corrected by the head tube correction part 30, and then the rear fork end is detected by the scale 41. If it does not match, the scale 41 is deflected to one side, and then the dial plate 44 is deflected to the end position, and the card slot is clamped at the rear fork end, and the dial plate 44 is pried by the pry bar 43 to correct the rear fork end up or down, which is easier to exert force and control the force than the hammering method.

[0030] See also Figure 1 The middle tube fixing member 20 includes a bracket 21 and a pressing cylinder 22. The pressing cylinder 22 is installed on the bottom plate 10 through the bracket 21. The telescopic end of the pressing cylinder 22 and the corresponding position on the bottom plate 10 are both provided with a pressing head 23, and the pressing head 23 presses on the five-way bracket of the frame. After the frame lies on its side on the bottom plate 10, one end of the five-way bracket of the frame is sleeved on the pressing head 23 below, and the pressing cylinder 22 presses down so that the upper pressing head 23 presses on the other end of the five-way bracket of the frame, thereby fixing the five-way bracket.

[0031] See also Figure 1 The middle tube fixing member 20 also includes a horizontal clamp 24, which is mounted on the bottom plate 10 and is pressed against the upper opening of the middle tube of the frame. The horizontal clamp 24 is pressed against the upper opening of the middle tube of the frame and fixes the middle tube of the frame up and down together with the lower pressure cylinder 22.

[0032] See also Figure 1-Figure 2 The head tube correction part 30 includes a slide 31 and a horizontal cylinder 32. The slide 31 is slidably connected to the base plate 10, and the two ends of the horizontal cylinder 32 are respectively connected to the slide 31 and the base plate 10. The head tube correction part 30 also includes a head rod 33. The slide 31 is provided with a groove adapted to the head rod 33, and the head rod 33 is inserted into the head tube of the frame. The head rod 33 is inserted into the head tube of the frame, and the horizontal cylinder 32 pushes the slide 31 to move inward. If the position of the head tube is correct, the head rod 33 will smoothly enter the groove on the slide 31. If it cannot enter the groove, the head tube part needs to be corrected until it enters the groove smoothly.

[0033] See also Figure 1-Figure 4 The rear fork correction member 40 further includes a slide bar 45, which is axially slidably connected to the rotating rod 42, and a paddle 44 is fixedly connected to the slide bar 45. The slide bar 45 moves up and down with the paddle 44, and then rotates, so that the two ends of the rear fork can be corrected respectively.

[0034] See also Figure 1-Figure 4 The rear fork correction member 40 further includes a gear 46 and a rack 47, the rack 47 is fixedly connected to the slide bar 45, the gear 46 is detachably meshed with the rack 47, and the gear 46 is fixedly connected to the pry bar 43. The pry bar 43 is deflected to drive the gear 46 to rotate, thereby driving the rack 47, the slide bar 45 and the paddle 44 to move up and down, thereby applying an upward or downward torque to the end of the rear fork.

[0035] See also Figure 1-Figure 4 The rear fork correction member 40 further includes a T-shaped slide groove 48, in which the gear 46 slides. The T-shaped slide groove 48 is arranged horizontally, and the rotating shaft of the gear 46 is stuck in the slide groove 48, and can be pulled backward to disengage from the meshing with the rack 47, and then the slide bar 45 and the paddle 44 can move up and down freely, so as to align the card slot on the paddle 44 with one of the ends of the rear fork, and then the gear 46 slides forward to mesh with the rack 47, and moves downward or upward along the T-shaped slide groove 48, so as to prevent the gear 46 from being disengaged from the rack 47 when exerting force.

[0036] The working principle of the bicycle frame production correction platform is as follows: after the frame lies on its side on the bottom plate 10, one end of the frame five-way is sleeved on the lower pressure head 23, the lower pressure cylinder 22 presses down so that the upper pressure head 23 presses on the other end of the frame five-way, thereby fixing the five-way, the horizontal clamp 24 is pressed against the upper end opening of the frame middle tube, and together with the lower pressure cylinder 22, the frame middle tube is fixed up and down, the head rod 33 is inserted into the frame head tube, and the horizontal cylinder 32 pushes the slide 31 to move inward, as shown in FIG. If the head tube is in the correct position, the head rod 33 will smoothly enter the groove on the slide 31. If it cannot enter the groove, the head tube part needs to be corrected until it enters the groove smoothly, and the deflection scale 41 is rotated. If the scale 41 matches the end of the rear fork, it means that the frame does not need to be corrected. Otherwise, the scale 41 is deflected to one side, the pry bar 43 and the gear 46 are pulled backward to disengage from the meshing with the rack 47, and then the slide bar 45 and the pry bar 44 are rotated to the other side. The gear 46 can be freely moved up and down so that the slot on the paddle 44 can be aligned with one of the ends of the rear fork, and then the gear 46 slides forward to engage with the rack 47 and moves downward or upward along the T-shaped slide groove 48, thereby preventing the gear 46 from being disengaged from the rack 47 when exerting force, and the pry bar 43 is deflected to drive the gear 46 to rotate, thereby driving the rack 47, the slide bar 45 and the paddle 44 to move up and down, thereby applying an upward or downward torque to the end of the rear fork, and the correction torque can be intuitively controlled by the deflection angle. In summary, after the middle tube fixing part 20 fixes the frame, the head tube part of the frame is corrected by the head tube correction part 30, and then the rear fork end is detected by the ruler 41. If it does not match, the ruler 41 is deflected to one side, and then the paddle 44 is deflected to the end position, the slot is stuck at the end of the rear fork, and the pry plate 44 is pried by the pry bar 43 to correct the end of the rear fork up or down. Compared with the hammering method, it is easier to exert force and control the force.
