Description

Technical Field

[0001] This utility model relates to the field of bicycle manufacturing auxiliary tools, and in particular to a bicycle handlebar positioning clamp. Background Technology

[0002] Bicycle components, a collective term for all parts and accessories of a bicycle frame, can be categorized into main types based on the overall structural framework of the bicycle, such as the frame, tires, pedals, fork assembly, chain, and freewheel. These basic components work together to form the foundation for the normal operation of a bicycle, and none can be omitted. In recent years, with the development of materials science, carbon fiber, with its significant advantages of light weight, high strength, high rigidity, and high plasticity, has been widely used in the manufacture of core bicycle components. More and more bicycle manufacturers are applying carbon fiber to key parts such as frames and handlebars, actively promoting the iterative upgrade of high-end sports bicycle products. As the core component of a bicycle's control system, the handlebars play a crucial role in controlling direction and maintaining balance during riding. Riders use the handlebars to change the direction of the front wheel, achieving agile steering and precise control of the bicycle's trajectory. At low speeds, during sharp turns, or when navigating complex road conditions, riders need to use the handlebars to constantly adjust their center of gravity and bicycle posture to ensure stability and safety. Especially in carbon fiber bicycles, lightweight, high-strength carbon fiber handlebars further enhance riding sensitivity and comfort, becoming a key element in high-end bicycle design. Currently, carbon fiber bicycle handlebars require drilling at specific locations during production to facilitate the assembly of other components. Positioning fixtures are needed to clamp the handlebars during drilling. However, existing positioning fixtures are inadequate in this regard, easily wobbling during processing. Furthermore, most existing fixtures use bolts for fastening, which is complex, cumbersome, and time-consuming. Therefore, improvements are needed. To address these issues, a bicycle handlebar positioning fixture is proposed. Utility Model Content

[0003] This utility model proposes a bicycle handlebar positioning clamp, which aims to improve the problems in the prior art where some devices tend to wobble when clamping carbon fiber bicycle handlebars, resulting in low accuracy of drilling positions, and the complex and time-consuming operation of bolt fastening.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A bicycle handlebar positioning clamp includes a processing table, a positioning mechanism fixedly connected to the top of the processing table, an auxiliary fixing mechanism fixedly connected to the top of the processing table, a head end positioning piece fixedly connected to the outer side of the processing table, a connecting bolt threadedly connected to the outer side of the processing table, and a rotating connecting plate threadedly connected to the outer side of the connecting bolt. The positioning mechanism includes a positioning block, the bottom of which is fixedly connected to the top of the processing table. A hinge is fixedly connected to the outside of the positioning block, and a positioning pressure block is fixedly connected to the outside of the hinge. A reinforcing and anti-slip component is fixedly connected to the bottom of the positioning pressure block. A locking positioning component is slidably connected between the positioning pressure block and the inside of the positioning block. A positioning groove is provided on the top of the positioning block, and a carbon fiber handlebar is provided on the top of the positioning groove.

[0005] The above solution utilizes a processing table as a base support. The positioning mechanism and auxiliary fixing mechanism work together. The positioning groove of the positioning block initially positions the carbon fiber handlebar. The positioning pressure block connected by the hinge is locked by the snap-fit ​​positioning component. Reinforced anti-slip components enhance the clamping and anti-slip effects. In the auxiliary fixing mechanism, the control component drives the elliptical locking block, controlling the clamping slider and clamping locking plate to clamp and release the handlebar. The head-end positioning plate assists in positioning and drilling the handlebar, and the connecting bolts and rotating connecting plate facilitate rotation during processing. This solution achieves precise positioning and secure clamping. The snap-fit ​​quick-release structure improves efficiency, reduces costs, and ensures the processing accuracy and stability of the handlebar.

[0006] As a further description of the above technical solution: The locking and positioning assembly includes an unlocking button, the outer side of which is slidably connected to the inner side of the positioning block. A reset spring is sleeved on the outer side of the unlocking button. A locking rod is slidably connected to the inner side of the positioning block. A locking spring is fixedly connected to the outer side of the locking rod.

[0007] The above solution allows the unlocking button to slide within the positioning block. A return spring on the outside of the button resets it upon pressing. The locking rod inside the positioning block, under the force of the locking spring, inserts into the positioning block's slot, locking the positioning block to itself. Pressing the unlocking button releases the locking rod from the slot, unlocking the block; releasing it resets it. This design ensures stable handlebar positioning, convenient operation, and improves the efficiency of the clamp.

[0008] As a further description of the above technical solution: One end of the reset spring is fixedly connected to the inner side of the positioning block, the other end of the unlocking button is fixedly connected to the outer side of the unlocking button, and the end of the engaging spring away from the engaging rod is fixedly connected to the inner side of the positioning block.

[0009] The above solution involves a reset spring that connects the positioning block and the unlocking button, providing a rebound force after the button is pressed to ensure it quickly resets. A locking spring is fixed to the inside of the positioning block, continuously providing elastic force to the locking rod, allowing it to be securely inserted into the slot and locking the positioning block and the positioning spring together. This synergistic effect ensures the handlebar is clamped securely, simplifies the unlocking process, and improves the ease of use and clamping reliability of the positioning clamp.

[0010] As a further description of the above technical solution: The reinforced anti-slip assembly includes a compression spring, the outer side of which is fixedly connected to the bottom of the positioning block. An anti-slip clamp is fixedly connected to the end of the compression spring away from the positioning block, and the bottom of the anti-slip clamp contacts the top of the carbon fiber handlebar.

[0011] The above solution involves a reinforced anti-slip assembly consisting of a compression spring and an anti-slip clamp. The compression spring is fixed to the bottom of the positioning block and generates elastic force through elastic deformation, continuously pressing the anti-slip clamp against the carbon fiber handlebar to enhance the clamping force. The bottom of the anti-slip clamp contacts the top of the handlebar, and its surface texture increases friction. At the same time, it conforms to the shape of the handlebar to evenly distribute pressure, preventing the handlebar from slipping during processing and avoiding localized stress damage. This provides a reliable guarantee for accurate handlebar positioning and stable processing.

[0012] As a further description of the above technical solution: The auxiliary fixing mechanism includes a clamping slider, an unlocking groove is provided on the top of the processing table, the bottom of the clamping slider is slidably connected to the inner side of the unlocking groove, a clamping locking plate is fixedly connected to the outer side of the clamping slider, the outer side of the clamping locking plate is in contact with the carbon fiber handlebar, and a control component is fixedly connected to the top of the processing table.

[0013] The above solution provides a sliding guide for the unlocking groove, which in turn drives the clamping locking plate, which is adapted to the shape of the handlebar, to move closer to or away from the handlebar under the operation of the control component, thereby clamping and releasing. The operator drives the clamping slider to slide in the unlocking groove through the control component, so that the clamping locking plate fits tightly against the handlebar, enhancing the fixing effect, ensuring the stability of the handlebar during the processing, and improving the processing accuracy.

[0014] As a further description of the above technical solution: A limiting guide rod is fixedly connected to the outside of the clamping slider, and a second return spring is sleeved on the outside of the limiting guide rod. A locking strip is fixedly connected to the end of the limiting guide rod away from the clamping slider.

[0015] The above solution utilizes a limiting guide rod to guide the sliding movement of the clamping slider, while a second return spring provides the restoring force, causing it to automatically return to its original position after being released. The locking strip secures the limiting guide rod and can also cooperate with other components to achieve eccentric clamping, enhancing the handlebar's stability and ensuring processing stability.

[0016] As a further description of the above technical solution: The control assembly includes a control handle, the bottom of which is rotatably connected to the top of the processing table. An elliptical locking block is fixedly connected to the bottom of the control handle. The outer side of the elliptical locking block is slidably connected to the outer side of the clamping slider. The outer side of the elliptical locking block is slidably connected to the outer side of the locking strip.

[0017] The above solution consists of a control handle and an elliptical locking block. The operator rotates the control handle to rotate the elliptical locking block. By utilizing the different positions of its long and short shaft ends, the operator can squeeze or release the clamping slider and locking plate, thereby clamping and releasing the locking plate on the handlebar. The operation is simple, the fixed state is precisely controlled, and the efficiency of the fixture and the stability of the handlebar processing are improved.

[0018] As a further description of the above technical solution: The inner side of the other clamping slider is slidably connected to the outer side of the limiting guide rod, one end of the second reset spring is fixedly connected to the outer side of the clamping slider, and the other end of the second reset spring is fixedly connected to the outer side of the other clamping slider.

[0019] The above solution works as follows: when the clamping slider is moved by an external force to clamp the handlebar, the return spring releases its elasticity when the external force is removed, so that the two clamping sliders automatically return to their original positions. This ensures that the auxiliary fixing mechanism can work repeatedly and stably, improving the convenience and efficiency of the handlebar fixing operation.

[0020] This utility model has the following beneficial effects: 1. In this utility model, the carbon fiber handlebar is first placed in the positioning groove of the positioning block for initial positioning. Then, the hinge is rotated to close the positioning block. At this time, the locking rod is inserted into the slot and locked under the action of the locking spring. The reinforced anti-slip component prevents the handlebar from sliding, achieving the effect of precise positioning and firm clamping of the handlebar. The positioning groove and the positioning block cooperate to provide a reliable positioning reference, ensuring that the handlebar installation and processing position is accurate, effectively improving processing accuracy and stability. Compared with the traditional bolt connection, this snap-fit ​​quick-release structure can also improve production efficiency, reduce manual calibration costs, and extend the service life of the fixture.

[0021] 2. In this utility model, the operator rotates the control handle, causing the elliptical locking block to rotate. When rotated to the horizontal position, the long shaft end abuts against the locking strip and the clamping slider, causing the clamping slider to slide in the unlocking groove, driving the clamping locking plate to approach and fit against the handlebar to complete the fixation. Rotating to the short shaft releases the handlebar, thus ensuring that even complex bent parts of the handlebar can be firmly fixed during processing, effectively avoiding the impact of shaking and displacement on processing accuracy. It also avoids the displacement and deflection of the handlebar caused by a single fixing mechanism during processing, improving processing accuracy and quality. Moreover, the operation is simple, and the return spring can also make the clamping slider automatically return to its original position, facilitating the next operation. Overall, it improves the efficiency of the positioning fixture and the stability and safety of handlebar processing. Attached Figure Description

[0025] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a bicycle handlebar positioning fixture, including a processing table 1. The processing table 1 is the basic load-bearing component of the entire fixture, capable of withstanding various external forces generated during handlebar positioning and processing. A positioning mechanism 2 is fixedly connected to the top of the processing table 1, and an auxiliary fixing mechanism 3 is fixedly connected to the top of the processing table 1. A head end positioning piece 5 is fixedly connected to the outer side of the processing table 1. The head end positioning piece 5 is used to position the head end of the bicycle handlebar.

The rotating connecting plate 7 is used to be fixed on the rotating part of the processing machine, which facilitates flipping processing during processing. The positioning mechanism 2 includes a positioning block 201, which is used to place the carbon fiber handlebar 4 for initial positioning. The bottom of the positioning block 201 is fixedly connected to the top of the processing table 1. A hinge 202 is fixedly connected to the outside of the positioning block 201. The hinge 202 allows the positioning pressure block 203 to open and close smoothly, realizing the clamping and loosening operation of the handlebar. The positioning pressure block 203 is fixedly connected to the outside of the hinge 202. The positioning pressure block 203 cooperates with the positioning block 201 to clamp and position the handlebar. When closed, it can completely cover the top of the handlebar and provide uniform pressure. The bottom of the positioning pressure block 203 is fixed. The positioning block 201 is connected by a reinforcing and anti-slip component 206. The positioning block 203 and the positioning block 201 are internally slidably connected by a locking positioning component 205. The top of the positioning block 201 is provided with a positioning groove 204. The positioning groove 204 is a key part of the top of the positioning block 201 used to place the carbon fiber handlebar 4. The surface is smooth to prevent scratches on the handlebar during positioning and clamping. It provides a positioning base and a reliable reference for subsequent processing or assembly processes. The top of the positioning groove 204 is provided with the carbon fiber handlebar 4. The carbon fiber handlebar 4 is the main part to be processed and can be processed after clamping and positioning. Specifically, the processing table 1 serves as the basic load-bearing structure, bearing the external forces generated during handlebar positioning and processing. The positioning mechanism 2 and auxiliary fixing mechanism 3 are fixedly connected at the top to position and fix the bicycle handlebar. The head-end positioning plate 5 is used for the head-end positioning of the handlebar, and its through hole facilitates subsequent drilling. The connecting bolt 6 connects the rotating connecting plate 7 to the processing table 1. The rotating connecting plate 7 is fixed on the rotating part of the processing machine for easy flipping processing. In the positioning mechanism 2, the positioning block 201 is used to place the carbon fiber handlebar 4 for initial positioning. The hinge 202 connects the positioning pressure block 203 to make it open and close. The reinforcing anti-slip component 206 at the bottom of the positioning pressure block 203 cooperates with the locking positioning component 205 inside the positioning block 201 and the positioning pressure block 203 to clamp the handlebar. The positioning groove 204 at the top of the positioning block 201 has a smooth surface, providing a placement position and positioning reference for the carbon fiber handlebar 4 so that subsequent processing of the handlebar can be carried out. When the positioning pressure block 203 is closed, it can completely cover the top of the handlebar and provide uniform pressure to ensure the stability of the handlebar during processing. The locking and positioning assembly 205 includes an unlocking button 20501, which is a key component for the operator to unlock the positioning block 203. The unlocking button 20501 has an anti-slip texture on its outer side for easy pressing by hand. The outer side of the unlocking button 20501 is slidably connected to the inner side of the positioning block 201. A return spring 20502 is sleeved on the outer side of the unlocking button 20501, providing a return force to the unlocking button 20501 so that it automatically returns to its initial position after the operator releases the pressure. A locking rod 20503 is slidably connected to the inner side of the positioning block 203, which is responsible for locking the positioning block 203 to the positioning position. The key component for locking the position block 201 is the positioning block 201, which can connect the positioning block 201 and the positioning pressure block 203 to achieve locking and fixation, and initially fix the position of the handlebar. The outer side of the locking rod 20503 is fixedly connected to the locking spring 20504, which provides elastic force to the locking rod 20503 in the direction of the slot, ensuring that the locking rod 20503 is always in the locked position inserted into the slot under normal conditions. One end of the return spring 20502 is fixedly connected to the inner side of the positioning block 201, and the other end of the unlocking button 20501 is fixedly connected to the outer side of the unlocking button 20501. The end of the locking spring 20504 away from the locking rod 20503 is fixedly connected to the inner side of the positioning pressure block 203. Specifically, the anti-slip texture on the outer side of the unlocking button 20501 facilitates the operator's application of force to press and unlock the positioning block 203. The return spring 20502 provides a restoring force to the unlocking button 20501 after the pressing operation, returning it to its initial position and ensuring the continuity and convenience of the operation. The locking rod 20503, as the core component for locking the positioning block 203 and the positioning block 201, works in conjunction with the elastic force provided by the locking spring 20504 towards the slot to stably insert into the slot, firmly locking the positioning block 203 and the positioning block 201, reliably and initially fixing the handlebar position, ensuring that the handlebar will not shift during processing. This achieves both stable clamping of the handlebar and unlocking through a simple pressing operation, effectively improving the ease of use and clamping stability of the bicycle handlebar positioning clamp, and providing a guarantee for the precise processing of the handlebar. Reference Figure 3 and Figure 5 The reinforced anti-slip component 206 includes a compression spring 20601, which provides pressure to the anti-slip clamp 20602 in the direction of the handlebars, enhancing the clamping effect and anti-slip capability of the handlebars. The outer side of the compression spring 20601 is fixedly connected to the bottom of the positioning block 203. The end of the compression spring 20601 away from the positioning block 203 is fixedly connected to the anti-slip clamp 20602. The striped texture of the anti-slip clamp 20602 further increases its friction with the surface of the handlebars, preventing the handlebars from sliding relative to each other during processing. At the same time, the shape of the anti-slip clamp 20602 fits well with the surface of the handlebars, and can evenly transmit the pressure of the compression spring 20601, achieving reliable clamping and positioning of the handlebars. The bottom of the anti-slip clamp 20602 is in contact with the top of the carbon fiber handlebar 4. Specifically, the reinforced anti-slip component 206 plays a key role in strengthening fixation and preventing slippage in the bicycle handlebar positioning clamp. One end of the compression spring 20601 is fixed to the bottom of the positioning block 203, continuously providing pressure towards the handlebar to the anti-slip clamp 20602. The elastic force generated by the elastic deformation enhances the clamping force on the handlebar, ensuring that the handlebar is stable and does not loosen during processing. The striped texture on the surface of the anti-slip clamp 20602 significantly increases the friction with the handlebar surface, effectively suppressing the relative slippage of the handlebar caused by external forces during processing. At the same time, its shape design that fits closely to the handlebar surface can evenly distribute the pressure of the compression spring 20601, avoiding damage to the handlebar due to uneven local force, and achieving reliable clamping and precise positioning of the carbon fiber handlebar 4, providing accuracy and stability for subsequent handlebar processing. Reference Figures 1 to 3The auxiliary fixing mechanism 3 includes a clamping slider 302. When the clamping slider 302 moves in the groove, it drives the clamping locking plate 301 to move closer to or away from the carbon fiber handlebar 4, thereby realizing the clamping and releasing operation of the handlebar. The top of the processing table 1 is provided with an unlocking groove 303. The unlocking groove 303 provides high-precision guidance for the sliding of the clamping slider 302. The bottom of the clamping slider 302 is slidably connected to the inner side of the unlocking groove 303. The outer side of the clamping slider 302 is fixedly connected with the clamping locking plate 301. The shape of the clamping locking plate 301 is the same as the outer contour of the handlebar. It can fit tightly with the surface of the handlebar and firmly fix the handlebar on the processing table 1. Furthermore, an anti-slip pad can be pasted on the side that contacts the handlebar to further enhance the clamping effect of the handlebar and protect the surface of the handlebar from being scratched. The outer side of the clamping locking plate 301 contacts the carbon fiber handlebar 4. The top of the processing table 1 is fixedly connected with a control component 305. A limiting guide rod 306 is fixedly connected to the outer side of the clamping slider 302. The limiting guide rod 306 serves to limit and guide the sliding of the clamping slider 302. A second return spring 307 is sleeved on the outer side of the limiting guide rod 306. The second return spring 307 provides a return force to the clamping slider 302, so that the clamping slider 302 can automatically return to the initial position after being released under the control of the control component 305. A locking strip 304 is fixedly connected to the end of the limiting guide rod 306 away from the clamping slider 302. The locking strip 304 serves to support and fix the limiting guide rod 306, and can contact subsequent components to achieve eccentric clamping and fixing. The inner side of another clamping slider 302 is slidably connected to the outer side of the limiting guide rod 306. One end of the second reset spring 307 is fixedly connected to the outer side of the clamping slider 302, and the other end of the second reset spring 307 is fixedly connected to the outer side of the other clamping slider 302. Specifically, the cooperation between the clamping slider 302 and the unlocking groove 303 provides high-precision guidance for its sliding, enabling the clamping slider 302 to accurately drive the clamping locking plate 301 closer to or further away from the carbon fiber handlebar 4, realizing the clamping and releasing operation of the handlebar. The clamping locking plate 301 has the same shape as the handlebar and fits tightly against the handlebar surface. The anti-slip pad attached to its contact side can not only enhance the clamping effect, but also protect the handlebar surface from scratches, ensuring that the handlebar is firmly fixed on the processing table 1. The limiting guide rod 306 limits and guides the sliding of the clamping slider 302. To ensure the stability and accuracy of the clamping operation, the second return spring 307 provides a return force to the clamping slider 302. After the control component 305 releases the slider, the clamping slider 302 automatically returns to its initial position for easy operation next time. The locking bar 304 supports and fixes the limit guide rod 306 and can cooperate with subsequent components to achieve eccentric clamping and fixation, further improving the fixing effect. The overall auxiliary fixing mechanism 3 enhances the fixing ability of the handlebar through the coordinated operation of various components, ensuring that the handlebar remains stable during processing, thereby improving processing accuracy and quality. The control component 305 includes a control handle 30501, which facilitates the operator to control the action of the auxiliary fixing mechanism 3. The bottom of the control handle 30501 is rotatably connected to the top of the processing table 1. An elliptical locking block 30502 is fixedly connected to the bottom of the control handle 30501. The elliptical locking block 30502 rotates with the rotation of the control handle 30501. When the elliptical locking block 30502 rotates to the horizontal position, its long axis end abuts against the locking bar 304 and the clamping slider 302, causing the clamping locking plate 301 to be squeezed inward, thus clamping the carbon fiber handlebar 4. When it rotates to the short axis, the squeezing of the locking bar 304 and the clamping slider 302 is released, realizing the release operation. The outer side of the elliptical locking block 30502 is slidably connected to the outer side of the clamping slider 302, and the outer side of the elliptical locking block 30502 is slidably connected to the outer side of the locking bar 304. Specifically, the control component 305, as the operating center of the bicycle handlebar positioning fixture, significantly improves the ease of operation and accuracy of the auxiliary fixing mechanism 3. The operator rotates the control handle 30501 to change the position of the elliptical locking block 30502 at the bottom. When the elliptical locking block 30502 rotates to the horizontal direction, its long axis end abuts against the locking strip 304 and the clamping slider 302, pushing the clamping locking plate 301 to clamp the carbon fiber handlebar 4. When rotated to the short axis direction, the compression is released. Under the action of the return spring 307, the clamping slider 302 drives the clamping locking plate 301 to reset and release. With its simple operation, this component can quickly and accurately clamp and release the handlebar, which not only improves the efficiency of the positioning fixture but also ensures the stability and safety during handlebar processing.

[0026] Working principle: First, place the carbon fiber handlebar 4 on the positioning groove 204 on the top of the positioning block 201, and align it with the hole on the head end positioning piece 5 for initial positioning. Then, rotate the positioning pressure block 203 around the hinge 202 to close it. During the closing process, the locking rod 20503 is inserted into the corresponding slot of the positioning block 201 under the elastic force of the locking spring 20504, thereby locking the positioning pressure block 203 and the positioning block 201. At this time, in the reinforcement anti-slip component 206 at the bottom of the positioning pressure block 203, the compression spring 20601 provides pressure to the anti-slip clamp 20602 in the direction of the handlebar. The anti-slip clamp 20602 contacts the top of the handlebar to prevent the handlebar from sliding, thus completing the initial fixation. Next, clamping and fixing are performed. The operator rotates the control handle 30501 in the control component 305. The control handle 30501 drives the elliptical locking block 30502 to rotate. When the elliptical locking block 30502 rotates to the horizontal position, its long shaft end abuts against the locking strip 304 and the clamping slider 302, so that the clamping slider 302 slides in the unlocking groove 303, driving the outer clamping locking plate 301 to move closer to the carbon fiber handlebar 4 and fit tightly, thus firmly fixing the handlebar on the processing table 1. After all-around fixing is completed, the rotating connecting plate 7 is fixed on the rotating part of the processing machine. It is used to perform multi-position drilling in conjunction with rotation. After processing, first rotate the control handle 30501 to rotate the elliptical locking block 30502 to the short axis direction, releasing the pressure on the locking strip 304 and the clamping slider 302. Under the action of the second return spring 307, the clamping slider 302 drives the clamping locking plate 301 to reset and release. Then press the unlocking button 20501 to overcome the elasticity of the first return spring 20502 and push the locking rod 20503 out of the slot, unlocking the positioning block 203. Open the positioning block 203 around the hinge 202 to remove the carbon fiber handlebar 4.
