Description

Technical Field

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

[0002] In the motorcycle manufacturing industry, a motorcycle handlebar tube primarily consists of a handlebar tube and a handlebar tube mount. The handlebar tube is straight at its beginning and end, with a curved middle section. The center of this curved section is welded to the top of the handlebar tube mount, which is a round tube. The motorcycle's steering column is inserted through the lower end of the handlebar tube mount and secured with bolts. The driver controls the straight tube at the beginning and end of the handlebar tube, transmitting steering force to the handlebar tube mount and steering column, which then controls the direction of the motorcycle's front wheel.

[0003] The Chinese patent application number CN202121673878.3 discloses a steel pipe bending machine, including a frame, on which a rotating component is provided for rotating the end of the steel pipe. The rotating component includes a rotating member rotatably arranged on the frame, a clamping block slidably connected to the rotating member, and a limit member for fixing the clamping block. There are two clamping blocks, and the two clamping blocks are arranged opposite to each other.

[0004] As the applicant conducted further research, it was found that since this technical solution lacked a structure to clamp and fix the pipe during bending, the pipe began to shake during processing. This was especially true for longer pipes, where the bending part was located closer to the end, and the shaking was more obvious. The pipes would swing along with the processed part, which could seriously endanger the surrounding parts and personnel safety. Utility Model Content

[0034] like Figure 1 - Figure 8 As shown, the present invention is a bending device for motorcycle handlebars, comprising a frame 1, a force applying device 2, a moving device 3 and a clamping device 4;

[0035] Among them, a guide rail 10 is provided at the upper end of the frame 1 along the length direction of the frame 1;

[0036] The force applying device 2 applies a bending force to the peripheral wall of the pipe 6;

[0037] The moving device 3 is connected to the side of the frame 1, and the moving device 3 adjusts the position of the force-applying device 2;

[0038] The clamping device 4 includes a sliding body 40 slidably connected to the guide rail 10. The sliding body 40 has a connecting rod 41. The connecting rod 41 is located near the side of the force-applying device 2 and has a clamping head 42 that cooperates with the pipe 6. A sliding sleeve 43 is provided between the main body of the connecting rod 41 and the clamping head 42 and is sleeved on the outer periphery of the connecting rod 41.

[0039] The side of the sliding body 40 is connected to a pushing assembly 5, which is used to control the axial movement of the sliding sleeve 43 along the connecting rod 41;

[0040] After the sliding sleeve 43 acts on the clamping head 42 , the clamping head 42 releases or clamps the end of the pipe 6 .

[0041] When using this equipment, according to the length of the pipe 6, the screw mechanism can be used to drive the clamping device 4 to move on the guide rail 10, adjust the relative distance between the clamping device 4 and the force-applying device 2, and the moving device 3 adjusts the specific position of the force-applying device 2. Then, one end of the pipe 6 is inserted into the clamping head 42, and the pipe 6 to be processed faces the force-applying device 2, and the pipe body is placed in the force-applying device 2.

[0042] A clamping device 4 is provided on the frame 1, and the end of the pipe 6 can be fixed by the clamping device 4, so that when the pipe 6 is bent, the remaining unprocessed part of the pipe 6 will not shake, eliminating safety hazards, and at the same time the bending quality of the pipe 6 is better guaranteed.

[0043] The clamping device 4 adopts a pushing component 5 to move the sliding sleeve 43 axially along the connecting rod 41, so that it controls the opening and closing of the clamping head 42, and can adapt to pipe fittings 6 of different diameters, and has better adaptability. Among them, the cooperation form of the sliding sleeve 43 and the clamping head 42 is simple in structure compared with the existing cylinder or screw structure, and there is no need to add an accessory structure near the pipe fitting 6, which occupies a small space and has good reliability.

[0044] Specifically, the pushing assembly 5 includes a telescopic member 50 and a pushing ring 51 hinged to a free end of the telescopic member 50 and sleeved on the outer periphery of the sliding sleeve 43 .

[0045] The pushing assembly 5 serves as a power assembly for driving the clamping head 42 . The telescopic member 50 driven by the pushing assembly 5 can be a cylinder. The extension and contraction of the cylinder is used to control the rotation of the hinged pushing ring 51 .

[0046] The push ring 51 has a side ear 511 on its side, and the push ring 51 is hinged to the sliding body 40 via the side ear 511 .

[0047] Specifically, an annular groove 430 is formed on the circumference of the sliding sleeve 43 , and protrusions 510 extending into the annular groove 430 are symmetrically provided on the inner side of the pushing ring 51 .

[0048] After the pushing ring 51 is acted upon, an axial force is generated on the sliding sleeve 43 through the protrusion 510, causing the sliding sleeve 43 to move axially and cooperate with the clamping head 42 to achieve the effect of controlling the opening and closing of the clamping head 42. Compared with the existing clamping structure arranged on the outside of the pipe fitting 6, this structure is arranged axially, and its structure is relatively compact, which is more suitable for the fixing of the end of the bent pipe fitting 6.

[0049] A limit block 410 is provided on the peripheral wall of the connecting rod 41, and a limit groove 431 is provided on the peripheral wall of the sliding sleeve 43 to cooperate with the limit block 410. The structure of the limit block 410 and the limit groove 431 allows the sliding sleeve 43 to rotate during its coaxial axial movement relative to the connecting rod 41. Furthermore, the limit groove 431 is elongated. Although the travel distance of the sliding sleeve 43 is directly determined by the travel of the telescopic member 50, the provision of the elongated limit groove 431 prevents the sliding sleeve 43 from overtravelling due to inertia, thereby limiting the travel distance of the sliding sleeve 43.

[0050] The force applying device 2 and the moving device 3 are both existing technologies. For their specific structures and connection forms, reference may be made to the technical solutions mentioned in the background technology.

[0051] Furthermore, specifically, the clamping head 42 includes a clamping seat 420 , a limiting shaft 421 coaxially connected to the clamping seat 420 , and a plurality of clamping claws 423 evenly distributed in the circumferential direction of the limiting shaft 421 .

[0052] The end of the clamping seat 420 is provided with notches 4200 , the same number as the clamping claws 423 . The tail ends of the clamping claws 423 are placed in the notches 4200 and are hinged to the clamping seat 420 .

[0053] In order to achieve the best clamping stability, the number of the clamping claws 423 is three.

[0054] In addition, the outer side of the gripping body of the clamping claw 423 has an inclined guide surface 424 that cooperates with the inner wall of the sliding sleeve 43.

[0055] This inclined guide surface 424 is a necessary feature of the clamping claws 423. As the sliding sleeve 43 approaches the clamping head 42 and its inner wall contacts the clamping claws 423, the sliding sleeve 43 exerts a radially inward compressive force against the inclined guide surface 424, causing the multiple clamping claws 423 to simultaneously rotate inward and retract, achieving a clamping effect. After the pipe 6 is bent, the end of the pipe 6 is released, and the operation and control of the clamping head 42 are reversed to the above description and will not be further described here.

[0056] Among them, when the sliding sleeve 43 retreats, the clamping claw 423 needs to restore the original opening and closing angle, which can be restored by the action of the spring. Specifically, the clamping claw 423 and the limiting shaft 421 are both provided with a groove 426 on the opposite side thereof, and the groove 426 is used for installing the spring.

[0057] The limiting shaft 421 is circumferentially provided with connecting ears 422 connected to the end of the clamping seat 420. The limiting shaft 421 is fixedly installed by the connecting ears 422.

[0058] The above are only embodiments of the present invention. Common knowledge such as the known specific structures and characteristics in the scheme is not described in detail here. Ordinary technicians in the relevant field are aware of all common technical knowledge in the technical field of the utility model before the application date or priority date, can obtain all existing technologies in the field, and have the ability to apply conventional experimental means before that date. Ordinary technicians in the relevant field can improve and implement this scheme based on their own abilities under the guidance of this application. Some typical known structures or methods should not become obstacles for ordinary technicians in the relevant field to implement this application. It should be pointed out that for those skilled in the art, without departing from the structure of the utility model, they can also make several variations and improvements, which should also be regarded as the scope of protection of the utility model. These will not affect the effect of the implementation of the utility model and the practicality of the patent.
