Description

Technical Field

[0001] This invention belongs to the field of bicycle parts production equipment, and in particular, a handlebar grip and wristband installation fixture. Background Technology

[0002] With people's pursuit of a low-carbon and healthy lifestyle, the demand for bicycles is increasing, and people also have higher requirements for riding comfort. As a crucial contact point between the rider and the bicycle, the handlebars' feel directly impacts the riding experience. Therefore, manufacturers typically cover the handlebars with a soft and durable cushioning layer. To prevent the handlebars from loosening or falling off during subsequent use, manufacturers add a wristband at the end of the handlebars to secure it. After the handlebars are installed, the wristband is located inside the handlebars. The wristband is usually an injection-molded part with a pre-cut opening, through which a locking bolt can be installed. However, after injection molding, the opening closes, causing the wristband to shrink in size. Therefore, it cannot be directly installed at the end of the handlebars. Workers must open the wristband from the opening to enlarge its size before it can be fitted onto the end of the handlebars. This installation process is difficult, time-consuming, and labor-intensive, resulting in high labor costs and low production efficiency, making mass production impossible. Summary of the Invention

[0003] To overcome the shortcomings of the existing problems mentioned above, the present invention provides a handlebar grip wristband installation fixture that can open the wristband, shape it with a cylinder, make the size of the wristband after opening larger than the size of the end of the grip, and finally smoothly install the wristband into the grip.

[0004] The technical solution adopted by this invention to solve its technical problem is: The handlebar grip and wristband installation fixture includes an installation platform 10 and a handlebar grip positioning unit 20 and a wristband installation unit 30 arranged opposite each other on the installation platform 10. A lifting and pushing unit 40 is also provided between the handlebar grip positioning unit 20 and the wristband installation unit 30. The grip positioning unit 20 is fixedly installed on the installation platform 10, including a support base 24 and a grip positioning block 21 mounted on the support base 24, which has several grip positioning grooves 22 arranged horizontally side by side. The openings of the grip positioning grooves 22 all face the wristband installation unit 30. The grip positioning grooves 22 position the grip 50 in the correct position according to the contour, so that it will not be misaligned during installation. When it is necessary to put the wristband on a grip with a different shape, only the grip positioning block 21 needs to be replaced.

[0005] The wristband mounting unit 30 includes a support platform 1 fixedly connected to the mounting platform 10 and a pusher cylinder 2 fixedly mounted on the support platform 1. On the side of the support platform 1, several wristband opening columns 3 are also fixedly and protruding, their positions and numbers corresponding to the positions and numbers of the handlebar positioning grooves 22 on the handlebar positioning block 21, facing the handlebar positioning unit 20. Each wristband opening column 3 has a frustoconical structure; its thinner end has an outer diameter smaller than the inner diameter when the wristband is not opened, its thicker end has an outer diameter larger than the outer diameter of the handlebar end, and its thinner end faces the groove opening direction of the handlebar positioning groove 22. The pusher cylinder 2... On the movable end of the material cylinder 2, there is a hand ring push block 4 located above the hand ring opening column 3. On the lower part of the hand ring push block 4, there is an arc-shaped groove that matches the number, size and position of the hand ring opening columns 3, which can push the hand ring 60 out of the hand ring opening column 3. Above the hand ring push block 4, a pressing cylinder 5 is fixedly installed by a bracket. The movable end of the pressing cylinder 5 is connected to a horizontal fixing block 6. Below the horizontal fixing block 6, there are several cylindrical cylinders 7 located on the outside of the hand ring push block, which are vertically oriented towards the top of the thicker end of the hand ring support column 3 and correspond one-to-one with the number and position of the hand ring opening columns 3. The lifting and pushing unit 40 includes a lifting cylinder 41 fixedly mounted on the installation platform 10 and a top plate 42 mounted on the movable end of the lifting cylinder 41. A horizontal push-pull cylinder 43 with its movable end facing the handle positioning unit 20 is also fixedly mounted on the top plate 42. A push-back plate 44 is mounted on the movable end of the horizontal push-pull cylinder 43. The upper part of the push-back plate 44 has several upward-facing pushing slots 45, which correspond to the number and position of the wristband opening column 3, and are used to push the wristband 60 from the thinner end to the thicker end of the wristband opening column 3.

[0006] Preferably, the inner ring of the wristband 60 has inwardly protruding positioning steps 62 on both sides of the opening 61. The top surface of the wristband opening post 3 has a movable limiting groove 31 that can cooperate with the two positioning steps. This allows the wristband 60 to be positioned by the cooperation of the two positioning steps 62 and the movable limiting groove 31, ensuring that its opening 61 always faces upward and preventing the wristband 60 from rotating or shifting during the process of being pushed along the wristband opening post 3.

[0007] Preferably, a pressing plate 23 driven by a cylinder fixed to the side of the support base is provided above the grip positioning block 21, or a pressing plate is provided by magnetic attraction, for pressing the grip to prevent it from dislodging when the cylinder is pulled out.

[0008] Preferably, a guide rod is provided between the transverse fixing block 6 and the wristband push block 4 to guide the movement of the transverse fixing block.

[0009] As a preferred option, each cylinder is controlled by a solenoid valve controller to achieve semi-automatic production.

[0010] Preferably, the side of the support platform 1 is also provided with a limiting block for limiting the movement of the wristband push block 4.

[0011] The beneficial effects of this invention are: The handlebar grip and wristband installation fixture of this invention has an ingenious structure. Through the clever cooperation of the grip positioning unit, the wristband installation unit, and the lifting and pushing unit, the installation of the grip and wristband is semi-automated. The wristband installation process is convenient and quick, greatly reducing the installation difficulty, saving time and labor, and greatly improving production efficiency, enabling rapid mass production. Moreover, if wristbands need to be installed on grips of different shapes, only the grip positioning block needs to be replaced. The production is very flexible, the application range is very wide, and the practicality is strong, making it worthy of promotion. Attached Figure Description

That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0015] like Figure 1-20 As shown, the handlebar grip and wristband mounting fixture includes a mounting platform 10 and a grip positioning unit 20 and a wristband mounting unit 30 arranged opposite each other on the mounting platform 10. A lifting and pushing unit 40 is also provided between the grip positioning unit 20 and the wristband mounting unit 30. The grip positioning unit 20 is fixedly installed on the installation platform 10, including a support base 24 and a grip positioning block 21 mounted on the support base 24, which has several grip positioning grooves 22 arranged horizontally side by side. The openings of the grip positioning grooves 22 all face the wristband installation unit 30. The grip positioning grooves 22 position the grip 50 in the correct position according to the contour, so that it will not be misaligned during installation. When it is necessary to put the wristband on a grip with a different shape, only the grip positioning block 21 needs to be replaced.

[0016] The wristband mounting unit 30 includes a support platform 1 fixedly connected to the mounting platform 10 and a pusher cylinder 2 fixedly mounted on the support platform 1. On the side of the support platform 1, several wristband opening columns 3 are also fixedly and protruding, their positions and numbers corresponding to the positions and numbers of the handlebar positioning grooves 22 on the handlebar positioning block 21, facing the handlebar positioning unit 20. Each wristband opening column 3 has a frustoconical structure; its thinner end has an outer diameter smaller than the inner diameter when the wristband is not opened, its thicker end has an outer diameter larger than the outer diameter of the handlebar end, and its thinner end faces the groove opening direction of the handlebar positioning groove 22. The pusher cylinder 2... On the movable end of the material cylinder 2, there is a hand ring push block 4 located above the hand ring opening column 3. On the lower part of the hand ring push block 4, there is an arc-shaped groove that matches the number, size and position of the hand ring opening columns 3, which can push the hand ring 60 out of the hand ring opening column 3. Above the hand ring push block 4, a pressing cylinder 5 is fixedly installed by a bracket. The movable end of the pressing cylinder 5 is connected to a horizontal fixing block 6. Below the horizontal fixing block 6, there are several cylindrical cylinders 7 located on the outside of the hand ring push block, which are vertically oriented towards the top of the thicker end of the hand ring support column 3 and correspond one-to-one with the number and position of the hand ring opening columns 3. The lifting and pushing unit 40 includes a lifting cylinder 41 fixedly mounted on the installation platform 10 and a top plate 42 mounted on the movable end of the lifting cylinder 41. A horizontal push-pull cylinder 43 with its movable end facing the handle positioning unit 20 is also fixedly mounted on the top plate 42. A push-back plate 44 is mounted on the movable end of the horizontal push-pull cylinder 43. The upper part of the push-back plate 44 has several upward-facing pushing slots 45, which correspond to the number and position of the wristband opening column 3, and are used to push the wristband 60 from the thinner end to the thicker end of the wristband opening column 3.

[0017] The inner ring of the wristband 60 has inwardly protruding positioning steps 62 on both sides of the opening 61. The top surface of the wristband opening column 3 has a movable limiting groove 31 that can cooperate with the two positioning steps. This allows the wristband 60 to be positioned by the cooperation of the two positioning steps 62 and the movable limiting groove 31, ensuring that its opening 61 always faces upward and preventing the wristband 60 from rotating or shifting when pushed along the wristband opening column 3.

[0018] Above the grip positioning block 21, there is a pressing plate 23 driven by a cylinder fixed to the side of the support base, or a pressing plate is magnetically attached, used to press the grip to prevent it from dislodging when the cylinder is pulled out.

[0019] A guide rod is provided between the transverse fixing block 6 and the wristband push block 4 to guide the movement of the transverse fixing block.

[0020] Each cylinder is controlled by a solenoid valve controller to achieve semi-automatic production.

[0021] The side of the support platform 1 is also provided with a limiting block for limiting the movement of the wristband push block 4.

[0022] Work process: The grip sleeve is fixed in the grip sleeve positioning groove 22 of the grip sleeve positioning unit 20, and its end for mounting the wristband 60 faces the wristband mounting unit 30. The worker puts the injection-molded bracelet 60 onto the outer, thinner end of the bracelet, which is spread open on the outer side of the pillar 3, so that the opening faces upward. The lifting cylinder 41 lifts the top plate 42 to the position where the push plate 44 can push the wristband 60 backward along the wristband opening column 3. Then, the horizontal push-pull cylinder 43 on the top plate 42 moves to pull the push plate 44 backward, pushing the wristband 60 backward to gradually expand the wristband on the wristband opening column 3, making its opening 61 larger. When the wristband 60 is expanded to a size larger than the outer diameter of the end of the handle, and its opening is large enough to fit the cylinder 7, and it reaches below the cylinder 7, the lifting cylinder 41 and the horizontal push-pull cylinder 43 return to their original positions. The pressing cylinder 5 moves to push the cylinder 7 into the opening 60 above the wristband 60. Because of the presence of the cylinder 7, the opening 60 of the wristband 60 can be kept in an expanded state, and the expanded state of the wristband can be maintained. Then, the pushing cylinder 2 on the wristband mounting unit 30 moves, driving the wristband push block 4 and the cylinder 7 on it to move together. Moving the positioning unit 20 in the direction of the handle sleeve moves the wristband 60 forward. During the movement, the cylinder 7 moves synchronously with the wristband. When the wristband 60 is moved to a position where the outer diameter of the wristband opening column 3 is smaller than the inner diameter of the wristband 60, and when it is completely detached from the wristband opening column 3, the wristband 60 will gradually close together and tightly clamp the cylinder as the outer diameter of the wristband opening column decreases during the movement. It will be suspended by the cylinder 7 and will not fall down. After the wristband 60 gradually comes off the wristband opening column 3 and is then moved forward to the end of the handle sleeve 50, the pushing cylinder 2 stops moving. Then the pressing cylinder 5 moves, driving the cylinder 7 to move upward and pulling the cylinder 7 out of the opening of the wristband 60. Thus, the wristband 60 is fixed to the end of the handle sleeve 50 used for installing the wristband. After installation, the pushing cylinder 2 and the pressing cylinder 5 return to their original positions, and then the handle sleeve can be removed manually.

[0023] To continue the installation, simply repeat the steps above.

[0024] If you need to attach a wristband to grips of different shapes, you only need to replace the grip positioning block.

[0025] Therefore, the handlebar grip and wristband installation fixture of the present invention has an ingenious structure. Through the clever cooperation of the grip positioning unit, the wristband installation unit, and the lifting and pushing unit, the installation of the grip and wristband is semi-automated. The wristband installation process is convenient and quick, greatly reducing the installation difficulty, saving time and labor, and greatly improving production efficiency, enabling rapid mass production. Moreover, if wristbands need to be installed on grips of different shapes, only the grip positioning block needs to be replaced. The production is very flexible, the application range is very wide, and the practicality is strong, making it worthy of promotion.
