Description

Technical Field

[0001] This utility model relates to the technical field of vehicle frame repair equipment, and in particular to a multi-functional clamping mechanism for vehicle frame repair. Background Technology

[0002] In the production, repair, and painting of bicycle and electric vehicle frames, the stability and precise fixing of the frame are crucial for ensuring work quality. Traditional fixing methods often rely on simple brackets and universal clamps, which suffer from inherent drawbacks such as unstable fixing, poor adaptability, and cumbersome operation. For example, Chinese Patent Publication No. CN219906828U discloses an electric vehicle frame repair device, "including a base, a support component for supporting the electric vehicle frame, a lifting mechanism for driving the lifting component to rise and fall, and a sliding device for driving the lifting mechanism to slide; the support component is mounted on the lifting mechanism; the lifting mechanism is mounted on the sliding device; and the sliding device is mounted on the base." This solution, through lifting and sliding functions, initially achieves the adjustment of the height and longitudinal position of frames of different sizes, solving the problem of the adaptability of the base's height and length.

[0003] However, such existing technologies still have significant limitations. Their fixing methods typically rely solely on simple clamps to hold the frame, failing to accurately simulate the core load-bearing structures of a bicycle / electric bike frame (such as the front seat tube and rear dropout). This simple clamping method results in a small contact area with the frame tubing and unscientific fixing points. It cannot achieve comprehensive rigid locking, making it prone to loosening or wobbling under significant lateral or torsional forces. Furthermore, it cannot avoid the risk of damage to the frame tubing due to localized stress concentration. In addition, its limited functionality fails to provide unobstructed open space for maintenance, grinding, and painting operations on the bottom and circumference of the frame, restricting its application scope. Utility Model Content

[0004] Purpose of the invention: The purpose of this utility model is to provide a multi-functional clamping mechanism for bicycle / electric vehicle frame repair, which can achieve rapid and accurate spatial positioning and rigid clamping of bicycle / electric vehicle frames, while providing a fully unobstructed operating space for repair work.

[0005] Technical solution:

[0006] A multi-functional clamping mechanism for vehicle frame repair, comprising:

[0007] The lower support frame has a support leg at its lower end;

[0008] The first dimension adjustment system includes a first slide groove disposed at one end of the lower support frame and a second slide groove disposed at the other end of the lower support frame. The first slide groove and the second slide groove are vertically arranged. A first sliding seat that can slide along it and be locked is disposed in the first slide groove, and a second sliding seat that can slide along it and be locked is disposed in the second slide groove.

[0009] The second-dimensional adjustment system includes a horizontal slide bar horizontally disposed on the lower support frame, and at least one third slide seat disposed on the horizontal slide bar that can slide along it and can be locked.

[0010] The front-end fixing system includes a fourth sliding seat that can slide laterally and be locked on the upper end of the first sliding seat, and a front riser limiting mechanism disposed on the fourth sliding seat.

[0011] The rear-end fixing system includes a fifth sliding seat that can slide laterally and be locked on the upper end of the second sliding seat, and a rear axle simulation limiting mechanism disposed on the fifth sliding seat for simulating the rear wheel axle and inserting into the rear hooks on both sides of the frame.

[0012] The side-end fixing system includes a side-end limiting mechanism disposed on one of the third sliding seats.

[0013] Furthermore, it also includes a third-dimensional adjustment system, which includes a fourth sliding groove disposed on the upper end of the fourth sliding seat and a fifth sliding groove disposed on the upper end of the fifth sliding seat. The fourth and fifth sliding grooves are vertically arranged. A fourth sliding rod that can slide along and be locked is disposed in the fourth sliding groove. A fifth sliding rod that can slide along and be locked is disposed in the fifth sliding groove. A sixth sliding groove is fixedly disposed on the fourth sliding rod. A seventh sliding groove is fixedly disposed at the top end of the fifth sliding rod. The sixth and seventh sliding grooves are horizontally coaxially arranged. A top support frame is coaxially slidably sleeved on the sixth and seventh sliding grooves.

[0014] Furthermore, the front riser limiting mechanism includes a first rotating seat, with spiral locking clamps at both ends of the first rotating seat for controlling its locking or free rotation, a front riser support rod fixedly mounted on the upper end of the first rotating seat, and a front riser sleeve rod fixedly mounted on the upper end of the front riser support rod.

[0015] Furthermore, the rear axle simulation limiting mechanism includes a second rotating seat, with spiral locking clamps at both ends of the second rotating seat to control its locking or free rotation, and a rear axle simulation rod fixedly installed at the front end of the second rotating seat.

[0016] Furthermore, the front end of the second rotating seat has two or more fixed through holes, and the rear axle simulation rod has a threaded structure in the middle. The rear axle simulation rod passes through one of the fixed through holes and is fixed on the second rotating seat by a nut and the threaded structure.

[0017] Furthermore, the side-end limiting mechanism includes a side-end fixing plate that is fixedly disposed on the upper end of the third sliding seat, and the side-end fixing plate is provided with a spiral locking clamp facing the opposite side.

[0018] Furthermore, the sliding pairs between the first sliding seat and the first sliding groove, the second sliding seat and the second sliding groove, the third sliding seat and the transverse sliding rod, the fourth sliding seat and the first sliding seat, and the fifth sliding seat and the second sliding seat are all locked by a spiral locking clamp.

[0019] Furthermore, the sliding pairs between the fourth slide rod and the fourth slide groove, the fifth slide rod and the fifth slide groove, and the top support frame and the sixth and seventh slide grooves are all locked by a screw locking clamp.

[0020] Beneficial effects:

[0021] 1. Through the cooperation of the first and second dimensional adjustment systems, the positions of the front, rear and side support points of the mechanism can be quickly adjusted, easily adapting to various models with different wheelbases, frame heights and widths, achieving a high degree of versatility, and accurately positioning the frame on the required spatial coordinates.

[0022] 2. The front riser limiting mechanism and the rear axle simulated limiting mechanism are used as the core fixing points to constrain the frame from the stress source designed in the frame itself. The side limiting mechanism provides lateral support, which together form a stable spatial statically determinate structure. This effectively prevents any shaking or twisting of the frame during maintenance, ensuring the stability and safety of operation.

[0023] 3. All sliding seats, slides, and slide rods are locked together using a uniform screw locking clamp. Operators only need to tighten or loosen the knobs or wrenches to complete the adjustment and fixation of all positions, realizing an integrated operation process of "quick adjustment, precise positioning, and firm locking", which greatly improves the efficiency of frame clamping and adjustment.

[0028] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1

[0030] like Figure 1-4 As shown, a multi-functional clamping mechanism for vehicle frame repair includes...

[0031] The lower support frame 1 has a support leg 2 at its lower end. The lower support frame 1 and the support leg 2 together form a rigid base platform for the entire mechanism, which is used to bear the weight of the frame and various loads generated during maintenance, ensuring the overall stability of the mechanism during operation.

[0032] The first-dimensional adjustment system includes a first slide groove 3 located at one end of the lower support frame 1 and a second slide groove 4 located at the other end of the lower support frame 1. The first slide groove 3 and the second slide groove 4 are vertically arranged. A first sliding seat 5, which can slide along and be locked, is provided in the first slide groove 3, and a second sliding seat 6, which can slide along and be locked, is provided in the second slide groove 4. The first-dimensional adjustment system provides the main adjustment capability of the mechanism in the vertical direction (Z-axis). By moving the first sliding seat 5 and the second sliding seat 6 within the vertical slide grooves, the height of the front and rear fixing systems can be adjusted as a whole to adapt to the overall ground clearance of different frames or the needs of specific maintenance postures. After adjustment, the system is fixed by the locking mechanism.

[0033] The second-dimensional adjustment system includes a transverse slide bar 1001 horizontally mounted on the lower support frame 1. At least one third sliding seat 7 is mounted on the transverse slide bar 1001 and can be slidably and locked along it. The second-dimensional adjustment system provides the mechanism with adjustment capability in the horizontal transverse (Y-axis) direction. The third sliding seat 7 can carry its side-end fixing system and move along the transverse slide bar 1001, thereby adjusting the lateral support point to the most suitable position according to the length of the frame, achieving effective lateral limiting and support for the frame downtube or seat tube.

[0034] The front-end fixing system includes a fourth sliding seat 8 that can slide laterally and be locked onto the upper end of the first sliding seat 5, and a front riser limiting mechanism 10 disposed on the fourth sliding seat 8. The fourth sliding seat 8 of this system can move laterally on the first sliding seat 5, realizing precise positioning of the front-end fixing point in the Y-axis direction in the horizontal plane. Its core is the front riser limiting mechanism 10, which is used to connect with the front riser (head tube) of the frame and serves as the reference point for fixing the front end of the frame.

[0035] The rear-end fixing system includes a fifth sliding seat 9, which is laterally slidable and lockable on the upper end of the second sliding seat 6, and a rear axle simulation limiting mechanism 11 disposed on the fifth sliding seat 9 for simulating the rear wheel axle and inserting into the rear hooks on both sides of the frame. Similar to the front end, the fifth sliding seat 9 provides adjustment functionality for the rear-end fixing point in the Y-axis direction. The rear axle simulation limiting mechanism 11, through a crossbar simulating the bicycle's rear wheel axle, is directly inserted into the hooks at the rear end of the frame, forming a reference point for fixing the rear of the frame. The front and rear reference points together define the wheelbase and basic posture of the frame.

[0036] The side-end fixing system includes a side-end limiting mechanism 12 disposed on one of the third sliding seats 7. This system serves as an auxiliary stabilization system, providing lateral support or clamping force to the main tubes of the frame (such as the lower tube), effectively preventing the frame from rotating or swaying laterally in the horizontal plane. It works in conjunction with the front and rear fixing points to form a stable spatially determinate structure.

[0037] Furthermore, it also includes a third-dimensional adjustment system, which includes a fourth sliding groove 13 disposed on the upper end of the fourth sliding seat 8 and a fifth sliding groove 14 disposed on the upper end of the fifth sliding seat 9. The fourth sliding groove 13 and the fifth sliding groove 14 are arranged vertically. A fourth sliding rod 15 that can slide along and be locked is disposed in the fourth sliding groove 13. A fifth sliding rod 16 that can slide along and be locked is disposed in the fifth sliding groove 14. A sixth sliding groove 17 is fixedly disposed on the fourth sliding rod 15. A seventh sliding groove 18 is fixedly disposed at the top end of the fifth sliding rod 16. The sixth sliding groove 17 and the seventh sliding groove 18 are arranged horizontally and coaxially. A top support frame 19 is coaxially slidably fitted on the sixth sliding groove 17 and the seventh sliding groove 18. The third-dimensional adjustment system is an optional top frame extension module for installing a top limiting module, which is not provided in this embodiment. The top limiting module can be similar to the three fixing systems mentioned above, or it can be a simple clamping mechanism.

[0038] Furthermore, the front riser limiting mechanism 10 includes a first rotating seat 101. Both ends of the first rotating seat 101 are provided with helical locking clamps 20 to control its locking or free rotation. A front riser support rod 102 is fixedly mounted on the upper end of the first rotating seat 101, and a front riser sleeve rod 103 is fixedly mounted on the upper end of the front riser support rod 102. The first rotating seat 101 allows the front riser support rod 102 to rotate within a certain angle range, thereby adapting to front risers with different inclination angles and ensuring that the front riser sleeve rod 103 can be accurately aligned and vertically inserted.

[0039] Furthermore, the rear axle simulation limiting mechanism 11 includes a second rotating seat 111, with spiral locking clamps 20 at both ends of the second rotating seat 111 for controlling its locking or free rotation, and a rear axle simulation rod 112 fixedly disposed at the front end of the second rotating seat 111.

[0040] Furthermore, the front end of the second rotating seat 111 has two or more fixing through holes 113. The rear axle simulation rod 112 has a threaded structure in the middle. The rear axle simulation rod 112 passes through one of the fixing through holes 113 and is fixed to the second rotating seat 111 by a nut 114 in conjunction with the threaded structure. The second rotating seat 111 makes the angle of the rear axle simulation rod 112 adjustable, ensuring that it can be horizontally and accurately aligned with the rear hooks on both sides of the frame. The rear axle simulation rod 112 simulates the real rear axle, and after inserting the hooks, the positioning and fixation of the rear of the frame is completed.

[0041] Furthermore, the side-end limiting mechanism 12 includes a side-end fixing plate 121 fixedly disposed on the upper end of the third sliding seat 7, and a spiral locking clamp 20 is disposed on the opposite side of the side-end fixing plate 121. The side-end fixing plate 121 serves as a base, and a clamping block is installed at the end of the spiral locking clamp 20 thereon. By tightening the clamp, its end abuts against the downtube or seat tube of the frame, thereby providing an adjustable lateral support force and eliminating the lateral degree of freedom of the frame.

[0042] Furthermore, the sliding pairs between the first sliding seat 5 and the first sliding groove 3, the second sliding seat 6 and the second sliding groove 4, the third sliding seat 7 and the transverse sliding rod 1001, the fourth sliding seat 8 and the first sliding seat 5, and the fifth sliding seat 9 and the second sliding seat 6 are all locked by a screw locking clamp 20. The screw locking clamp utilizes the principle of threaded force amplification, generating significant friction by rotating the handle to drive the clamping block, thereby firmly locking the sliding seat to the sliding groove or sliding rod. This method provides reliable locking and quick, easy operation, making it crucial for achieving the "quick clamping" function.

[0043] Furthermore, the sliding pairs between the fourth slide rod 15 and the fourth slide groove 13, the fifth slide rod 16 and the fifth slide groove 14, and the top support frame 19 and the sixth and seventh slide grooves 17 and 18 are all locked by a screw locking clamp 20. This design ensures that the third-dimensional adjustment system has the same locking reliability and operational consistency as the main mechanism in all adjustment dimensions.

[0044] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
