Description

Technical Field

[0001] The utility model belongs to the technical field of motorcycle parts processing, and particularly relates to a straightening device for the raw material of a handlebar tube. Background Art

[0002] Existing motorcycle handlebar tubes are all formed by bending a steel pipe under the action of a pipe bender. The two ends of the handlebar tube are used to install handlebar rubber sleeves to form handlebar segments.

[0003] As the steel pipe used as the raw material of the handlebar tube, its straightness needs to be ensured before bending treatment. If it is found that the raw material steel pipe has obvious bending during inspection, a straightening treatment needs to be carried out first before bending treatment.

[0004] As Figure 4 shown, a Chinese patent with the application number CN202110352016.9 discloses a straightening device for a connecting pipe, which includes a base, a pressing mechanism and a straightening mechanism; the pressing mechanisms are arranged in pairs at both ends of the base 9, and each pressing mechanism includes a pressing support seat, a pressing slider and a pressing screw rod; the pressing support seat is in a U shape, the bottom is slidably connected to the base, and a lower pressing groove 8 for placing a tubular part 6 is arranged at the bottom; the pressing slider is arranged inside the pressing support seat, and an upper pressing groove for fixing the connecting pipe is arranged at the bottom, and the upper pressing groove is arranged opposite to the lower pressing groove 8.

[0005] With further research by the applicant, it is found that in the straightening treatment of this technical solution, the tubular part is placed at the upper ends of two groups of lower pressing grooves, so that the middle part to be bent is under the action component. Although this solution can straighten the tubular part, since the lower pressing groove is fixed, it cannot adjust the relative position on the base according to the tubular parts of different models and lengths, especially for small handlebar tubes, resulting in insufficient support or no support for the tubular part by the lower pressing groove, which brings trouble to the straightening work.

Therefore, the terms describing the positional relationship in the accompanying drawings are only for illustrative purposes and cannot be construed as a limitation on this patent. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0030] As Figure 1 - Figure 5 As shown, a straightening device for the raw material of a handlebar tube of the present utility model includes an operating table 1, a support frame 2, a mounting frame 3, and a lifting assembly 4;

[0031] Among them, a chute 10 is opened along the length direction at the upper end of the operating table 1;

[0032] The support frame 2 is connected to the bottom of the operating table 1;

[0033] The mounting frame 3 is arranged on the upper part of the operating table 1 and is connected to the side part of the operating table 1;

[0034] The lifting assembly 4 is connected to the mounting frame 3, and a applying head 5 acting on the outer wall of the tubular member 6 is connected to the bottom of the lifting assembly 4;

[0035] Among them, at least two groups of sliding support blocks 7 are slidably connected to the operating table 1. A limiting projection 71 extending into the chute 10 is provided at the bottom of the sliding support block 7, and a limiting groove 72 for placing the tubular member 6 is opened at the upper end of the sliding support block 7.

[0036] Adopt the form that two groups of sliding support blocks 7 slide relative to each other on the operating table 1. On the basis of providing support for the tubular part 6, the sliding support block 7 moves in the sliding groove 10 to adjust the relative distance between the sliding support block 7 and the lifting assembly 4, which can adapt to tubular parts 6 of different lengths, can make targeted adjustments, and has better support performance;

[0037] When local micro-calibration of the tubular part 6 is required, the sliding support block 7 can be moved and close to the lifting assembly 4. When the lifting assembly 4 applies a downward force on the tubular part 6, compared with the traditional fixed straightening device, the local micro-calibration effect is better.

[0038] Among them, the cross-section of the limiting groove 72 is V-shaped. When placing the tubular part 6, the tubular part 6 is located in the V-shaped limiting groove 72, restricting the tubular part 6 to move only along the length of the operating table 1. The V-shaped design can adapt to tubular parts 6 of various outer diameters.

[0039] In addition, the sliding support block 7 can be composed of several sliding pieces 70 stacked together. The number of the sliding pieces 70 can be increased or decreased to change the thickness of the sliding support block 7, so as to change the extension length of the limiting groove 72. When dealing with a larger outer diameter or requiring more reliable support performance, it can be achieved by increasing the number of the sliding pieces 70.

[0040] Specifically, fastening holes are provided on the sliding piece 70, and through the cooperation of fasteners and the fastening holes, several sliding pieces 70 are tightly connected together.

[0041] In addition, the cross-section of the force-applying head 5 is V-shaped, and its specific structure can refer to the limiting sliding support block 7.

[0042] Among them, the lifting assembly 4 can be a screw mechanism that drives the force-applying head 5 to move longitudinally, and the screw mechanism is provided with a ratchet mechanism for driving the screw mechanism to operate.

[0043] Of course, the lifting assembly 4 can also adopt other structures with lifting functions, such as telescopic cylinders, etc.

[0044] In addition, a cushion pad can be arranged at the bottom of the support frame 2, and the cushion pad can adopt materials with a buffering effect such as rubber materials, which can reduce the damage to the ground and improve the mechanical stability performance at the same time.

[0045] The above are only embodiments of the present utility model. Specific structures and common knowledge such as characteristics that are well-known in the art are not described in detail herein. Those of ordinary skill in the art know all the common general technical knowledge in the technical field to which the utility model pertains before the filing date or the priority date, can acquire all the existing technologies in this field, and have the ability to apply the conventional experimental means before this date. Those of ordinary skill in the art can, under the inspiration given in this application, combine their own abilities to complete and implement this solution. Some typical well-known structures or well-known methods should not become obstacles for those of ordinary skill in the art to implement this application. It should be noted that for those skilled in the art, without departing from the structure of the present utility model, several deformations and improvements can still be made, and these should also be regarded as the protection scope of the present utility model, and these will not affect the implementation effect of the present utility model and the practicality of the patent.
