Technical Field
[0001] This utility model relates to the field of bicycle gluing equipment technology, and in particular to a universal gluing fixture for bicycle frames. Background Technology
[0002] As a key process equipment in the manufacturing of carbon fiber bicycle frames, the bonding jig for bicycle frames has evolved from a single fixed type to a modular design. Currently, most mainstream bonding jigs adopt a split-type fixing structure. Its working principle is as follows: using the bottom bracket of the frame as a reference positioning point, the seat tube and rear dropout are fixed by rigid clamps, and then the frame is assembled by the bonding process.
[0003] Early frame jigs were typically custom-made for specific frame models, lacking versatility and resulting in high production costs and low changeover efficiency. Current frame bonding jigs still struggle to adapt to different frame models and sizes.
[0004] Therefore, there is an urgent need for a new type of universal frame bonding fixture to solve the problem that current frame bonding fixtures are difficult to adapt to different models and sizes of frames. Utility Model Content

[0007] In one embodiment, the height adjustment assembly includes a support structure and a movable part; the support structure is provided with a groove that extends to the top of the support structure, a portion of the movable part is slidably disposed in the groove, and another portion of the movable part extends out of the groove and is connected to the seat tube fixing member.
[0008] In one embodiment, the movable part is bent, with one end of the movable part sliding in the groove and the other end of the movable part connected to the seat tube fixing member.
[0009] In one embodiment, the side wall of the support structure is provided with a first connecting hole, which communicates with the slide groove; the height adjustment component further includes a first fastener, which is connected to the first connecting hole; one end of the first fastener abuts against the movable part located in the slide groove; and / or, the side of the support structure is also provided with a blocking member, which blocks the side opening of the slide groove.
[0010] In one embodiment, the seatpost fixing member has a guide portion on the side facing the vehicle seatpost, and the guide portion has a tapered slope, the cross-sectional area of which gradually decreases in the direction toward the vehicle seatpost.
[0011] In one embodiment, the height adjustment component is provided with a second connection hole, and the bottom bracket includes a second fastener and a washer. One end of the second fastener passes through the washer and the first through hole in sequence and is connected to the second connection hole.
[0012] In one embodiment, the rear triangle includes a rear upper fork and a rear lower fork. One end of the rear upper fork and one end of the rear lower fork are connected to the seatpost of the vehicle. The ends of the rear upper fork and the rear lower fork are spaced apart. The other ends of the rear upper fork and the other ends of the rear lower fork meet at the rear dropout. The rear dropout has a second through hole. The universal frame bonding fixture also includes a base and a dropout fixing mechanism. The bottom of the height adjustment component is connected to the base, and the bottom of the dropout fixing mechanism is connected to the base. The dropout fixing mechanism is used to pass through the second through hole and fix the rear dropout.
[0013] In one embodiment, the hook fixing mechanism includes a main rod, a rotating component, and a locking component; the bottom of the main rod is rotatably connected to the base via the rotating component; a slide rail is provided on the top of the main rod, and the locking component slides in cooperation with the slide rail; the locking component is used to pass through the second through hole and lock the rear hook.

[0028] As a key process equipment in the manufacturing of carbon fiber bicycle frames, the bonding jig for bicycle frames has evolved from a single fixed type to a modular design. Currently, most mainstream bonding jigs adopt a split-type fixing structure. Its working principle is as follows: using the bottom bracket of the frame as a reference positioning point, the seat tube and rear dropout are fixed by rigid clamps, and then the frame is assembled by the bonding process.
[0029] Early frame jigs were typically custom-made for specific frame models, lacking versatility and resulting in high production costs and low changeover efficiency. Current frame bonding jigs still struggle to adapt to different frame models and sizes.
[0030] Therefore, there is an urgent need for a new type of universal frame bonding fixture to solve the problem that current frame bonding fixtures are difficult to adapt to different models and sizes of frames.
[0031] To address the aforementioned problems, this utility model proposes a universal gluing fixture for vehicle frames.
[0032] Please see Figures 1 to 2In one embodiment of this utility model, the universal frame bonding fixture 1 is applied to the vehicle frame 2. The vehicle frame 2 includes a front triangle 21 and a rear triangle 22. The front triangle 21 and the rear triangle 22 are connected to the seat tube 23. The lower end of the front triangle 21, the rear triangle 22, and the seat tube 23 intersects to form a bottom bracket 24. The bottom bracket 24 has a first through hole. The universal frame bonding fixture 1 includes a bottom bracket fixing member 11 and a seat tube fixing mechanism 12. The bottom bracket fixing member 11 passes through the first through hole and is connected to the seat tube fixing mechanism 12. The seat tube fixing mechanism 12 includes a height adjustment component 121 and a seat tube fixing member 122. The height adjustment component 121 has a vertically movable part 1211, which is connected to the seat tube fixing member 122. The height adjustment component 121 is used to adjust the height of the movable part 1211 so that the seat tube fixing member 122 extends into the seat tube 23 and fixes the seat tube 23.
[0033] The technical solution of this utility model adopts a universal frame bonding fixture 1, which includes a bottom bracket fixing member 11 and a seat post fixing mechanism 12. The bottom bracket fixing member 11 passes through the first through hole of the bottom bracket 24 and is connected to the seat post fixing mechanism 12, thereby fixing the bottom of the vehicle frame 2 to the seat post fixing mechanism 12 by using the bottom bracket fixing member 11. The seatpost fixing mechanism 12 includes a height adjustment component 121 and a seatpost fixing member 122. The moving part 1211 of the height adjustment component 121 is connected to the seatpost fixing member 122, so that the seatpost fixing member 122 can move with the moving part 1211, thereby allowing the seatpost fixing member 122 to extend into the body seatpost 23 and fix the body seatpost 23. In this way, the presence of the height adjustment component 121 allows the seatpost fixing member 122 to be adapted to body seatposts 23 of different models and heights, so that the seatpost fixing member 122 can smoothly extend into the body seatpost 23, and together with the bottom bracket fixing member 11 to fix the body bottom bracket 24, two-point positioning of the body seatpost 23 is achieved, and the body seatpost 23 is completely fixed.
[0034] Overall, the universal gluing fixture 1 for vehicle frames of this utility model fixes the bottom bracket 24 of the vehicle body through the bottom bracket fixing component 11, and through the cooperation between the height adjustment component 121 and the seat post fixing component 122, the seat post fixing component 122 can be inserted into the seat post 23 of different heights and sizes and fix the seat post 23, thereby achieving the adaptation to different models and sizes of vehicle frame 2.
[0035] It should be noted that the moving part 1211 of the height adjustment component 121 can move in various ways. For example, the moving part 1211 of the height adjustment component 121 can move by means of sliding groove and slider, or by means of sliding telescopic rod. These will not be described in detail here.
[0036] Furthermore, the front triangle 21 refers to the triangular area in the frame 2 near the front of the motorcycle. It should be noted that the front triangle 21 actually includes the top tube, down tube, head tube, and seat tube 23. These components form a quadrilateral area, but because the head tube is shorter than the top tube, down tube, and seat tube 23, this quadrilateral area approximates a triangle. Since this triangular area is close to the front of the motorcycle, it is commonly referred to as the front triangle 21 by those skilled in the art. The rear triangle 22 refers to the triangular area in the frame 2 that fits into the parking space. The rear triangle 22 typically includes the seat tube 23, the top stays, and the chain stays; the triangular area formed by these three components is the rear triangle 22. The front triangle 21 and rear triangle 22 intersect at the seat tube 23. The lower end of the front triangle 21, rear triangle 22, and seat tube 23 intersects at the bottom bracket 24, which connects the seat tube 23, down tube, and two chain stays, hence the name bottom bracket 24.
[0037] Please see Figures 1 to 2 In an embodiment of this utility model, the height adjustment component 121 includes a support structure 1212 and a moving part 1211; the support structure 1212 is provided with a sliding groove 1213, the sliding groove 1213 extends to the top of the support structure 1212, a part of the moving part 1211 is slidably disposed in the sliding groove 1213, and another part of the moving part 1211 extends out of the sliding groove 1213 and is connected to the seat tube fixing member 122.
[0038] In this embodiment, by providing a groove 1213 on the support structure 1212 and sliding a portion of the moving part 1211 into the groove 1213, the movable effect of the moving part 1211 of the height adjustment component 121 is achieved. The moving part 1211 drives the seat post fixing member 122 to move, thereby adjusting the height of the seat post fixing member 122 according to the actual height of different models and sizes of vehicle body seat posts 23, so that the seat post fixing member 122 extends into the vehicle body seat post 23 and fixes the vehicle body seat post 23.
[0039] As an optional implementation, the support structure 1212 can be configured as a series of supporting components such as brackets, rods, and support tubes. No specific restrictions are made on the specific type and structure of the support structure 1212.
[0040] Please see Figures 1 to 2In this embodiment of the utility model, the movable part 1211 is bent, one end of the movable part 1211 is slidably disposed in the sliding groove 1213, and the other end of the movable part 1211 is connected to the seat tube fixing member 122.
[0041] In this embodiment, by allowing one end of the movable part 1211 to slide within the slide groove 1213, one end of the movable part 1211 can slide along the slide groove 1213. Due to the bent shape of the movable part 1211, the other end of the movable part 1211 can be blocked by the top of the support structure 1212, effectively preventing the other end of the movable part 1211 from sliding into the slide groove 1213. This prevents the seat post fixing member 122 from falling into the slide groove 1213 and being unable to extend into the vehicle body seat post 23.
[0042] Please see Figures 1 to 2 In an embodiment of this utility model, the side wall of the support structure 1212 is provided with a first connecting hole, which communicates with the slide groove 1213; the height adjustment component 121 further includes a first fastener 1214, which is connected to the first connecting hole; one end of the first fastener 1214 abuts against the moving part 1211 located in the slide groove 1213; and / or, the side of the support structure 1212 is also provided with a blocking member 1215, which blocks the side opening of the slide groove 1213.
[0043] In this embodiment, a first fastener 1214 is used and connected to the first connecting hole. One end of the first fastener 1214 presses against the moving part 1211 located in the slide groove 1213, so that the moving part 1211 presses against the slide groove 1213 and forms friction to prevent the relative sliding of the moving part 1211. In this way, after the seat post fixing member 122 moves to the expected height, the relative height position of the moving part 1211 can be locked by the first fastener 1214, so as to prevent the moving part 1211 from sliding up and down and causing the seat post fixing member 122 to fail to fix the seat post 23 of the vehicle body.
[0044] The first fastener 1214 can be configured as a tightening knob, and the first connecting hole can be configured as a screw hole. The tightening knob is provided with threads, so that the tightening knob is threadedly connected to the screw hole. One end of the tightening knob presses against the moving part 1211 in the slide groove 1213, so that the moving part 1211 presses against the groove wall of the slide groove 1213 and forms friction, thereby hindering the relative sliding of the moving part 1211.
[0045] Please see Figures 1 to 2 In an embodiment of this utility model, the seat post fixing member 122 is provided with a guide portion 1221 on the side facing the vehicle seat post 23. The guide portion 1221 has a tapered inclined surface, and the cross-sectional area of the tapered inclined surface gradually decreases along the direction towards the vehicle seat post 23.
[0046] In this embodiment, a guide portion 1221 is provided on the side of the seat post fastener 122 facing the vehicle seat post 23, and the guide portion 1221 has a tapered slope. The tapered slope of the guide portion 1221 provides a guiding function for the seat post fastener 122, so that the seat post fastener 122 can extend into or partially extend into the vehicle seat post 23 in a suitable direction through the guide portion 1221 when facing different models and different sizes of vehicle seat posts 23, so as to achieve the fixation of the vehicle seat post 23. It should be noted that for seat tubes 23 with smaller diameters, the seat tube fixing member 122 itself may not be able to fully extend into the seat tube. However, since the guide part 1221 has a tapered slope, and the cross-sectional area of the tapered slope gradually decreases in the direction towards the seat tube 23, this tapered design allows the front end of the guide part 1221 to partially extend into the seat tube 23 with smaller diameters, thereby achieving stable fixing of seat tubes with different diameters and enabling fixing of seat tubes 23 with different models, different heights, and different diameters.
[0047] Please see Figures 1 to 2 In an embodiment of this utility model, the height adjustment component 121 is provided with a second connection hole, and the five-way fastener 11 includes a second fastener 111 and a gasket 112. One end of the second fastener 111 passes through the gasket 112 and the first through hole in sequence and is connected to the second connection hole.
[0048] In this embodiment, by using a second fastener 111 and a gasket 112, and providing a second connecting hole on the height adjustment component 121, one end of the second fastener 111 passes through the gasket 112 and the first through hole in sequence and connects with the second connecting hole, thereby achieving the locking and fixing of the vehicle body five-way connector 24.
[0049] In one optional implementation, the second fastener 111 can be a pin, with the second connecting hole configured as a pin hole. One end of the pin passes through the washer 112 and the first through hole in sequence, and is press-fitted into the pin hole, thereby locking and fixing the body five-way connector 24. Alternatively, in another optional implementation, the second fastener 111 can be a bolt, with the second connecting hole configured as a threaded hole. One end of the bolt passes through the washer 112 and the first through hole in sequence, and is threaded into the threaded hole, thereby locking and fixing the body five-way connector 24. Of course, the second fastener 111 and the second connecting hole can also adopt other connection methods, which will not be elaborated here.
[0050] Please see Figures 1 to 2In an embodiment of this utility model, the rear triangle 22 includes a rear upper fork 221 and a rear lower fork 222. One end of the rear upper fork 221 and one end of the rear lower fork 222 are connected to the seat post 23 of the vehicle body. The rear upper fork 221 and one end of the rear lower fork 222 are arranged at intervals. The other end of the rear upper fork 221 and the other end of the rear lower fork 222 meet at the rear dropout 223. The rear dropout 223 is provided with a second through hole. The universal frame bonding fixture 1 also includes a base 13 and a dropout fixing mechanism 14. The bottom of the height adjustment component 121 is connected to the base 13, and the bottom of the dropout fixing mechanism 14 is connected to the base 13. The dropout fixing mechanism 14 is used to pass through the second through hole and fix the rear dropout 223.
[0051] In this embodiment, the other end of the rear upper fork 221 and the other end of the rear lower fork 222 meet at the rear dropout 223. The rear dropout 223 has a second through hole. By allowing the dropout fixing mechanism 14 to pass through the second through hole and fix the rear dropout 223, and by connecting the bottom of the dropout fixing mechanism 14 to the base 13, the dropout fixing mechanism 14 and the base 13 can achieve precise positioning and stable fixation of the rear dropout 223. This design of the dropout fixing mechanism 14 and the base 13 ensures the geometric accuracy of the rear triangle 22 during the gluing process. At the same time, through the synergistic effect of the base 13 and the dropout fixing mechanism 14, a reliable support reference is provided for the rear of the frame, meeting the universal fixing requirements of frames of different sizes.
[0052] Please see Figures 1 to 2 In an embodiment of this utility model, the hook fixing mechanism 14 includes a main rod 141, a rotating component 142, and a locking component 143; the bottom of the main rod 141 is rotatably connected to the base 13 through the rotating component 142; a slide rail 1411 is provided on the top of the main rod 141, and the locking component 143 is slidably engaged with the slide rail 1411; the locking component 143 is used to pass through the second through hole and lock the rear hook 223.
[0053] In this embodiment, the hook fixing mechanism 14 includes a main rod 141, a rotating component 142, and a locking component 143. The bottom end of the main rod 141 is rotatably connected to the base 13 via the rotating component 142, allowing the main rod 141 to be angled. A slide rail 1411 is provided at the top of the main rod 141, and the locking component 143 forms a sliding engagement with the slide rail 1411, achieving linear displacement adjustment along the axial direction of the main rod 141. Thus, through the synergistic mechanism of the rotating connection and the sliding engagement, the locking component 143 can achieve a combined movement effect of axial movement relative to the main rod 141 and rotation relative to the rotating component 142, thereby achieving adaptation and locking of rear hooks 223 of different models and sizes, ensuring precise alignment and stable locking of the rear triangle 22 of the vehicle frame 2.
[0054] Please see Figures 1 to 2In an embodiment of this utility model, the rotating assembly 142 includes a first bracket 1421, a second bracket 1422, a rotating shaft 1423, and a third fastener 1424. The first bracket 1421 and the second bracket 1422 are connected to the base 13. The first bracket 1421 has a third through hole, and the main rod 141 has a fourth through hole. The rotating shaft 1423 passes through the third through hole and the fourth through hole. The third fastener 1424 is disposed on the second bracket 1422. The second bracket 1422 has a fifth through hole, and the main rod 141 has a third connecting hole. The third fastener 1424 passes through the fifth through hole. And connects to the third connecting hole; the third fastener 1424 is used to lock the main rod 141 onto the second bracket 1422; and / or, the locking assembly 143 includes a sliding member 1431, a sleeve rod 1432 and a fourth fastener 1433, the sliding member 1431 is slidably mounted on the slide rail 1411, the sliding member 1431 is disposed on the outer periphery of the sleeve rod 1432 along the axial direction, the end of the sleeve rod 1432 is provided with a fourth connecting hole, one end of the fourth fastener 1433 passes through the second through hole and connects to the fourth connecting hole, and the other end of the fourth fastener 1433 presses the rear claw 223 against the end of the sleeve rod 1432.
[0055] In this embodiment, the rotating assembly 142 includes a first bracket 1421, a second bracket 1422, a rotating shaft 1423, and a third fastener 1424. The first bracket 1421 has a third through hole, and the main rod 141 has a corresponding fourth through hole. The rotating shaft 1423 passes through both the third and fourth through holes to achieve a rotatable connection between the main rod 141 and the first bracket 1421. The second bracket 1422 has a fifth through hole, and the main rod 141 has a corresponding third connecting hole. The third fastener 1424 passes through the fifth through hole and is threaded into the third connecting hole. When the third fastener 1424 is tightened, it rigidly locks the main rod 141 to the second bracket 1422, ensuring the stability of the main rod 141 after adjustment. This rotating assembly 142 allows for stepless angle adjustment of the main rod 141 within a horizontal range of 0-180°, thus meeting the positioning requirements of the rear triangle 22 angle for different vehicle frames. In one optional implementation, the fifth through hole can be configured as an arc-shaped through hole, the extension direction of which is configured to extend along the rotation direction of the rotating assembly 142, so that the third fastener 1424 can lock the rotated main rod 141 along the rotation direction, thereby achieving the effect of locking the main rod 141 over a larger range.
[0056] In addition, in this embodiment, the locking assembly 143 further includes a sliding member 1431, a sleeve rod 1432, and a fourth fastener 1433. The sliding member 1431 forms a sliding engagement with the slide rail 1411, and the sliding member 1431 is disposed on the sleeve rod 1432, so that the sleeve rod 1432 can slide relative to the slide rail 1411. A fourth connecting hole is provided at the end of the sleeve rod 1432. One end of the fourth fastener 1433 passes through the second through hole of the rear claw 223 and is connected to the fourth connecting hole. The other end of the fourth fastener 1433 firmly presses the rear claw 223 onto the end face of the sleeve rod 1432 through a clamping nut, thereby achieving the locking effect of the rear claw 223. The locking assembly 143 achieves precise adjustment of the RC distance (i.e., the horizontal distance from the rear hook 223 to the center of the frame bottom bracket) through the cooperation of the slider 1431 and the slide rail 1411. Combined with the positioning function of the sleeve 1432 along the sliding direction of the guide rail, it ensures the precise positioning and reliable fixation of the rear hook 223 during the gluing process.
[0057] In one optional implementation, the third fastener 1424 can be a tightening knob, and the third connecting hole can be a threaded hole. The tightening knob has threads, allowing it to connect threadedly to the threaded hole. One end of the tightening knob presses against the main rod 141 to prevent its rotation, thus positioning the main rod 141 in the direction of rotation. Similarly, the fourth fastener 1433 can also be a tightening knob, and the fourth connecting hole can be a threaded hole, allowing it to connect threadedly to the threaded hole. The other end of the tightening knob, the rear claw 223, presses against the end of the sleeve rod 1432, locking the rear claw 223.
[0058] Since one-piece molding of carbon fiber frames is the industry's optimal design solution, the complex product structure and molding process currently prevent the front triangle 21 and rear triangle 22 of the frame from being entirely one-piece molded. Therefore, in this embodiment of the invention, the front triangle 21 is one-piece molded, and the rear upper fork 221 and rear lower fork 222 are glued together to form the rear dropout 223.
[0059] In this embodiment, by making the front triangle 21 integrally molded, the use of gluing process is minimized, the design and manufacturing costs of gluing fixtures are reduced, and production efficiency is improved.
[0060] In conjunction with any of the above embodiments, this embodiment provides an explanation of one operation method for the universal bonding fixture 1 for this vehicle frame:
[0061] First, adjust the seatpost fixing mechanism 12 and the hook-claw fixing mechanism 14 to a position that does not affect the universal bonding jig 1 on the upper frame of the body frame 2. Then, fix the body bottom bracket 24 of the body frame 2 to the bottom bracket fixing member 11, and adjust the moving part 1211 so that the seatpost fixing member 122 is inserted into the body seatpost 23. Lock the body seatpost 23 with the first fastener 1214 to fix the body seatpost 23. Next, adjust the third fastener 1424 in the hook-claw fixing mechanism 14 so that the main rod 141 can rotate relative to the rotating component 142. Adjust the position of the sliding member 1431 on the slide rail 1411 so that the second through hole of the body frame 2 is fixed on the locking component 143. Lock the fourth fastener 1433. Adjust the gap between the joints of the various parts of the body frame 2 by rotating the component 142. After adjustment, lock the main rod 141 with the third fastener 1424. Finally, put the fixed body frame 2 into the oven for baking.
