Description
Technical Field
[0001] This utility model relates to the field of carbon fiber bicycle frame bonding technology, specifically a carbon fiber bicycle frame bonding device. Background Technology
[0002] Carbon fiber bicycles are mainly mid-to-high-end racing bicycles. As an emerging material, carbon fiber is mainly used in frames (carbon frames), forks, wheelsets (carbon rims), etc. Some carbon fiber bicycle frame connections need to be connected by adhesive bonding. In this process, this device is needed to support and position the carbon fiber bicycle frame structure to be bonded, so as to prevent the carbon fiber bicycle frame from shaking or shifting during the bonding process.
[0003] In the prior art, a carbon fiber bicycle frame bonding device with the publication number "CN213566309U" uses movable clamping plates, mounting plates, and arc-shaped plates. The arc-shaped plates can clamp and fix the frame under the elastic force of the support springs. At the same time, the operation of the servo motor can drive the two movable clamping plates to clamp the frame. Then, the operation of the hydraulic cylinder can drive the mounting plate to move, so that the two frames can be bonded together.
[0004] However, the above technical solutions and existing technologies have the following drawbacks:
[0005] Although the bonding device can clamp and fix the frame through the arc plate and support spring, this structure can only clamp and fix round frames. It is inconvenient to clamp and fix non-circular frames. In actual use, the arc plate can only clamp round frames of different diameters within a small range, which limits the applicability of the device. Utility Model Content

The limiting guide rail 32 is fixedly connected to the upper surface of the operating table 1. The limiting guide rail 32 is connected to the operating table 1 by welding. The limiting guide rail 32 is T-shaped. The T-shaped limiting guide rail 32 can limit the movable support 31 and prevent the movable support 31 from deviating or shaking during lateral movement. The fixed support 37 is installed on the left side of the upper surface of the operating table 1. The fixed support 37 is connected to the fixed support frame 36 by welding. The fixed support 37 can support and fix the fixed support frame 36. The fixed support frame 36 is fixedly connected to the upper end of the fixed support 37.

[0029] The upper surface of the limiting guide rail 32 is fitted with a movable support seat 31. The movable support seat 31 and the movable support frame 35 are connected by welding. The movable support seat 31 can support the movable support frame 35. The upper surface of the movable support seat 31 is provided with the movable support frame 35, which can support another set of positioning components 4.

The multi-stage electric push rod 34 is connected between the side support plate 33 and the movable support seat 31. The multi-stage electric push rod 34 is electrically connected to the external control cabinet through wires. The multi-stage electric push rod 34 can drive the movable support seat 31 to move laterally left and right, thereby adjusting the distance between the fixed support frame 36 and the movable support frame 35.

The guide rail groove 38 facilitates the limiting guide rail 32 to limit and guide the movable support seat 31.
[0030] Example 2:
[0031] On the basis of the first embodiment, in this embodiment, by providing a V-shaped groove 47 on the upper end surface of the support base 48, circular carbon fiber bicycle frames with different diameters can be supported and positioned. The installed pressing screw 46 and L-shaped support plate 45 can contact and fix the circular carbon fiber bicycle frame placed in the V-shaped groove 47. By controlling the air pump 43 and the air inlet pipe 44 to inflate the tightening airbag 41, the tightening airbag 41 can be inflated to tighten and fix the non-circular carbon fiber bicycle frame rod inserted inside, thereby fixing carbon fiber bicycle frame rods of different shapes with a wide fixing range.
[0032] The positioning component 4 includes a tightening airbag 41, an extension support plate 42, an air pump 43, an air inlet pipe 44, an exhaust valve 49 and an air outlet pipe 411. Tightening airbags 41 are installed inside both the movable support frame 35 and the fixed support frame 36, and the shape of the tightening airbag 41 is in a figure-eight shape. After being inflated and expanded, the figure-eight-shaped tightening airbag 41 can flexibly clamp and fix the carbon fiber bicycle frame inserted in the fixed support frame 36 and the movable support frame 35. The air inlet end of the rear end surface of the tightening airbag 41 is connected to the air inlet pipe 44, and the air pump 43 is installed at the rear end of the air inlet pipe 44. The air pump 43 is electrically connected to an external control cabinet through a wire. The air inlet pipe 44 and the air pump 43 can inflate the inside of the tightening airbag 41.
[0033] Extension support plates 42 are provided on the rear end surfaces of both the movable support frame 35 and the fixed support frame 36. The extension support plates 42 are connected to the movable support frame 35 and the fixed support frame 36 by welding. The extension support plates 42 can support the air pump 43. The air outlet end of the front end surface of the tightening airbag 41 is connected to the air outlet pipe 411, and the exhaust valve 49 is installed at the front end of the air outlet pipe 411. The air outlet pipe 411 and the exhaust valve 49 can discharge the air inside the tightening airbag 41 to deflate it. A reinforcing plate 421 is fixedly connected to the lower end surface of the extension support plate 42, which makes the support stability of the extension support plate 42 better.
[0034] L-shaped support plates 45 are provided on the rear sides of the upper end surfaces of both the movable support frame 35 and the fixed support frame 36. The L-shaped support plates 45 are connected to the movable support frame 35 and the fixed support frame 36 by welding. The L-shaped support plates 45 can not only support the pressing screw 46, but also do not hinder the convenient placement of the carbon fiber bicycle frame on the support base 48. The pressing screw 46 is threadedly installed on the front side of the upper end surface of the L-shaped support plate 45. An internally threaded through hole 452 is provided on the front side of the upper end surface of the L-shaped support plate 45, and the internally threaded through hole 452 is threadedly connected to the pressing screw 46. The internally threaded through hole 452 enables the pressing screw 46 to have the ability to rise and fall when rotated forward or backward, so as to contact and fix the carbon fiber bicycle frame in the V-shaped groove 47 with the pressing screw 46.
[0035] Both the movable support frame 35 and the fixed support frame 36 have support seats 48 installed at the middle of their upper surfaces. The upper surface of each support seat 48 has a V-shaped groove 47. This V-shaped groove allows the support seat 48 to support and limit the movement of circular carbon fiber bicycle frames of different diameters. An anti-slip silicone sheet (shown in the figure) is adhered to the inner wall of the V-shaped groove 47. This anti-slip silicone sheet not only improves the anti-slip properties of the inner wall of the V-shaped groove 47 but also prevents hard contact between the support seat 48 and the carbon fiber bicycle frame. A reinforcing block 451 is fixedly connected to the upper side of the inner wall of the L-shaped support plate 45. Furthermore, the reinforcing block 451 is in the shape of a right triangle. The right triangle shape of the reinforcing block 451 improves the strength and deformation resistance at the corner of the L-shaped support plate 45. A turntable 461 is provided at the upper end of the clamping screw 46. The turntable 461 and the clamping screw 46 are an integral structure. The turntable 461 makes it convenient for workers to rotate the clamping screw 46 by hand. A rubber sheet 462 is bonded to the bottom of the clamping screw 46. The rubber sheet 462 is made of silicone rubber. The silicone rubber sheet 462 prevents hard contact between the clamping screw 46 and the carbon fiber bicycle frame.
[0036] Working principle: When bonding two identical round carbon fiber bicycle frame rods, the operator first places the two carbon fiber bicycle frame rods horizontally into the V-shaped grooves 47 on the upper surface of the two sets of support seats 48. After placement, the clamping screws 46 on both sides are rotated clockwise to lower them, so that the clamping screws 46 abut and position the carbon fiber bicycle frame rods placed in the V-shaped grooves 47. Then, by controlling the multi-stage electric push rod 34, the moving support seat 31 is moved inward. The moving support seat 31, through the moving support frame 35 and the support seat 48, moves the right side... The carbon fiber bicycle frame poles are moved inward so that the right carbon fiber bicycle frame poles can approach and contact the left carbon fiber bicycle frame poles, so that the workers can bond the connection between the two sets of carbon fiber bicycle frame poles. During this process, the V-groove 47 and the clamping screw 46 on the support base 48 can prevent the two sets of carbon fiber bicycle frame poles from shaking or shifting during the bonding process. After the bonding is completed, simply rotate the clamping screws 46 on the left and right sides counterclockwise to make them rise, and then the bonded round carbon fiber bicycle frame poles can be removed.
[0037] When it is necessary to support and fix non-circular carbon fiber bicycle frame poles, the operator simply inserts two identical non-circular carbon fiber bicycle frame poles into the tightening air bladders 41 inside the moving support 35 and the fixed support 36, respectively. Then, the two non-circular carbon fiber bicycle frame poles are aligned, connected, and held in place. Next, another operator controls the air pump 43 to inflate the tightening air bladders 41 through the air inlet pipe 44. This inflates the tightening air bladders 41, tightening and fixing the non-circular carbon fiber bicycle frame poles inserted inside. During the process, the staff who support the two non-circular carbon fiber bicycle frame poles by hand need to keep the joints of the two non-circular carbon fiber bicycle frame poles aligned to avoid misalignment. Once the non-circular carbon fiber bicycle frame poles are tightened and fixed, the air pump 43 can be turned off. Then, the joints of the non-circular carbon fiber bicycle frame poles are glued together. After the glue is completed, simply open the exhaust valve 49 to expel the air from the tightening airbag 41 and deflate it. At this point, the staff can pull the glued non-circular carbon fiber bicycle frame poles horizontally away.
