Description

Technical Field

[0001] This utility model relates to the field of motorcycle repair platforms, specifically an adjustable-height motorcycle repair platform. Background Technology

[0002] Motorcycle frame welding platforms are key equipment in motorcycle manufacturing. Specifically designed for frame welding, they enable high-precision assembly of welded parts. The platform is highly adaptable, allowing for rapid positioning and clamping, and is easy to reuse, significantly improving production efficiency, reducing costs, and ensuring the stability of welding quality.

[0003] Current motorcycle welding production lines mostly adopt an assembly line operation mode. When the motorcycle frame is transported to various processing stations, operators need to perform welding tasks. However, there is a problem in this process: there are multiple welding points on the motorcycle frame, and different positions are responsible for different welding points. Therefore, operators need to frequently move to different welding positions to perform operations. This back-and-forth position change not only increases the labor intensity, but also reduces the convenience and efficiency of welding operations on motorcycle frames. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an adjustable height motorcycle repair platform to solve the technical problem of reducing the difficulty of welding motorcycle frames by requiring operators to change positions back and forth during the motorcycle welding process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable height motorcycle repair platform, including a chain plate slide rail, on which several sliding plates are slidably connected, and a lower support frame is mounted on the sliding plates via a turntable. An upper support frame is provided above the lower support frame, and a locking mechanism is provided on one side of the top of the sliding plates to limit the rotation angle of the turntable.

[0006] The engaging mechanism includes a fixed frame with an installation groove on its inner side. Two sets of connecting arms are rotatably connected to the inner side of the installation groove via a rotating shaft. A movable frame is rotatably mounted on the outer side of the rotating shaft. An insert block is provided on one side of the movable frame. Several slots are equidistantly provided on the outer side of the turntable. A groove is provided on the surface of the fixed frame. A straight groove is provided on the connecting arm. A tension spring is connected between the movable frame and the inner wall of the installation groove.

[0007] By adopting the above technical solution, as the connecting arm rotates, the position of the insert changes accordingly, eventually separating from the slot, thereby removing the fixed restriction on the turntable. At this time, the operator can freely rotate the turntable, thereby driving the lower support frame and the motorcycle frame clamped above to adjust the angle to meet different welding or maintenance needs.

[0008] Furthermore, the insert block passes through the fixing frame via a through slot, the insert block is positioned opposite the slot, and the insert block engages with the slot.

[0009] By adopting the above technical solution, the stability and reliability of the locking mechanism when fixing the lower support frame are ensured. When the insert block is inserted into the slot, the tight fit between the two can effectively prevent the lower support frame from shaking or shifting during welding or maintenance, thereby improving the welding accuracy and maintenance quality of the motorcycle frame.

[0010] Furthermore, the two sets of connecting arms are mirror images of each other, and a handle is provided on one side of each connecting arm to provide the user with a point of force application for the connecting arm.

[0011] By adopting the above technical solution, a more convenient operating method is provided for operators. The mirror structure of the connecting arm allows operators to apply force more evenly when turning, avoiding uneven force on the locking mechanism caused by unilateral force application.

[0012] Furthermore, the slot is used to provide the range of motion of the two sets of connecting arm rotation shafts, and a limit rod is fixedly provided on the inner side of the mounting slot and opposite to the position of the straight slot to limit the range of motion of the connecting arm.

[0013] By adopting the above technical solution, the flexibility of the locking mechanism when adjusting the angle of the lower support frame is ensured. Through the slotted design, the connecting arm can rotate freely within a certain range, thereby meeting the welding or maintenance needs of the motorcycle frame at different angles.

[0014] Furthermore, the tension springs are provided in several groups to provide the engaging force between the plug and the slot.

[0015] By adopting the above technical solution, the sturdiness of the locking mechanism when fixing the lower support frame is ensured. The combined action of multiple sets of tension springs allows the insert to be tightly locked into the slot, and the lower support frame can remain stable even during high-intensity welding or maintenance.

[0016] Furthermore, a height adjustment mechanism is installed between the lower support frame and the upper support frame. The height adjustment mechanism includes a servo motor, and a lead screw is provided at the end of the servo motor. The lead screw is threadedly connected to the upper support frame through the lead screw sleeve. The lower support frame and the upper support frame are connected by a guide rod for adjusting the distance between the lower support frame and the upper support frame.

[0017] By adopting the above technical solution, the distance between the lower support frame and the upper support frame can be precisely adjusted, meeting the maintenance needs of motorcycle frames of different heights. Driven by the servo motor, the lead screw can move the upper support frame in the vertical direction, thereby achieving precise height adjustment.

[0018] Furthermore, the top of the upper support frame is provided with several fixed support frames and movable clamps for limiting and clamping the motorcycle frame.

[0019] By adopting the above technical solution, a stable limiting clamp is provided for the motorcycle frame, ensuring stability and safety during welding or repair. The fixed support frame can firmly support the bottom of the motorcycle frame, preventing it from moving or tilting during welding or repair.

[0020] In summary, the present invention has the following main advantages:

[0021] 1. This utility model utilizes a locking mechanism. By moving the connecting arm, the operator moves the insert block, eventually separating it from the slot. At this point, the turntable loses the fixing effect of the insert block and becomes rotatable. The operator can easily adjust the angle of the lower support frame via the turntable, thereby adjusting the angle of the motorcycle frame clamped above. Once the motorcycle frame is adjusted to the desired angle, the operator simply releases the force on the connecting arm. Under the action of the tension spring, the connecting arms and insert block gradually return to their initial state. During this return process, the insert block re-engages with the corresponding slot, thus achieving a stable fixation of the lower and upper support frames. This operation avoids the tedious back-and-forth position changes for the operator, greatly improving the convenience and efficiency of motorcycle frame welding.

[0022] 2. This utility model, by setting a height adjustment mechanism, realizes flexible and precise adjustment of the distance between the lower support frame and the upper support frame. This function is crucial for meeting the maintenance needs of motorcycle frames of different heights. Whether it is a small and lightweight motorcycle frame or a large and heavy frame, this device can ensure that the frame can be stably clamped in the device by adjusting the distance between the upper and lower support frames, providing solid support for subsequent maintenance or welding work.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0033] The embodiments of this utility model will be described below based on its overall structure.

[0034] Example 1:

[0035] An adjustable-height motorcycle repair platform, such as Figures 1-6As shown, it includes a chain plate slide rail 1, a plurality of sliding plates 2 are slidably connected on the chain plate slide rail 1, a lower support frame 301 is rotatably mounted on the sliding plate 2 via a turntable 6, an upper support frame 302 is provided above the lower support frame 301, and a locking mechanism 7 is provided on one side of the top of the sliding plate 2 to limit the rotation angle of the turntable 6.

[0036] The engaging mechanism 7 includes a fixed frame 701, with an installation groove 702 on its inner side. Two sets of connecting arms 703 are rotatably connected to the inner side of the installation groove 702 via a rotating shaft. A movable frame 708 is rotatably mounted on the outer side of the rotating shaft. A plug 709 is provided on one side of the movable frame 708. Several slots 711 are equidistantly provided on the outer side of the turntable 6. A slot 704 is provided on the surface of the fixed frame 701. A straight groove 705 is provided on the connecting arms 703. A tension spring 710 connects the movable frame 708 to the inner wall of the installation groove 702. As the connecting arms 703 rotate, the position of the plug 709 changes accordingly, eventually separating from the slot 711, thus releasing the engagement mechanism. With the turntable 6 fixed in place, the operator can freely rotate the turntable 6, thereby adjusting the angle of the lower support frame 301 and the motorcycle frame clamped above to meet different welding or maintenance needs. At the same time, once the motorcycle frame is adjusted to the required angle, the operator only needs to release the force applied to the connecting arm 703. Under the elastic restoring force of the tension spring 710, the movable frame 708 is automatically pulled back, causing the connecting arms 703 on both sides and the insert block 709 to gradually return to the initial position. During this process, the insert block 709 precisely engages in the corresponding slot 711, achieving a firm fixation of the lower support frame 301 and the upper support frame 302.

[0037] See Figure 4 , Figure 5 , Figure 6 The insert 709 passes through the fixing frame 701 via a through slot. The insert 709 and the slot 711 are positioned opposite each other and engage with each other, ensuring the stability and reliability of the engaging mechanism 7 when fixing the lower support frame 301. When the insert 709 is inserted into the slot 711, the tight fit between the two can effectively prevent the lower support frame 301 from shaking or shifting during welding or maintenance, thereby improving the welding accuracy and maintenance quality of the motorcycle frame. At the same time, this engaging method also makes the operation simpler. The operator only needs to move the connecting arm 703 to engage and disengage the insert 709 and the slot 711, which greatly improves work efficiency.

[0038] See Figure 4 , Figure 5 , Figure 6The two sets of connecting arms 703 are in a mirror structure. A handle 707 is provided on one side of the connecting arm 703, providing the user with a point of force application for the connecting arm 703. This provides the operator with a more convenient way to operate. The mirror structure of the connecting arm 703 allows the operator to apply force more evenly when turning it, avoiding uneven force on the locking mechanism 7 caused by applying force on one side. At the same time, the handle 707 also provides the operator with a clear point of force application, making it easier and more accurate to turn the connecting arm 703. This not only improves the convenience of operation but also reduces errors in the operation process, thereby improving the use effect of the motorcycle repair platform.

[0039] See Figure 5 , Figure 6 The slot 704 provides the range of motion for the rotating shafts of the two sets of connecting arms 703. A limit rod 706 is fixedly installed on the inner side of the mounting slot 702 and opposite to the position of the straight slot 705 to limit the range of motion of the connecting arm 703. This ensures the flexibility of the locking mechanism 7 when adjusting the angle of the lower support frame 301. Through the design of the slot 704, the connecting arm 703 can rotate freely within a certain range, thereby meeting the welding or repair needs of the motorcycle frame at different angles. At the same time, the setting of the limit rod 706 also effectively limits the range of motion of the connecting arm 703, enabling the connecting arm 703 to be rotatable. This flexible and stable design makes the motorcycle repair platform more capable of handling various complex repair tasks.

[0040] See Figure 5 , Figure 6 Several sets of tension springs 710 are provided to provide the engagement force between the insert 709 and the slot 711, ensuring the firmness of the engagement mechanism 7 when fixing the lower support frame 301. The combined action of multiple sets of tension springs 710 allows the insert 709 to be tightly inserted into the slot 711, maintaining the stability of the lower support frame 301 even during high-intensity welding or maintenance. At the same time, the elasticity of the tension springs 710 makes the engagement mechanism 7 operate more smoothly, easily achieving the engagement and disengagement of the insert 709 and the slot 711 without additional auxiliary tools or force.

[0041] Example 2:

[0042] See Figure 1 , Figure 2 , Figure 3A height adjustment mechanism 5 is installed between the lower support frame 301 and the upper support frame 302. The height adjustment mechanism 5 includes a servo motor 501, and a lead screw 503 is provided at the end of the servo motor 501. The lead screw 503 is threadedly connected to the upper support frame 302 through the lead screw sleeve. A guide rod 502 is connected between the lower support frame 301 and the upper support frame 302 to adjust the distance between the lower support frame 301 and the upper support frame 302. This achieves precise adjustment of the distance between the lower support frame 301 and the upper support frame 302, meeting the maintenance needs of motorcycle frames of different heights. Driven by the servo motor 501, the lead screw 503 can drive the upper support frame 302 to move in the vertical direction, thereby achieving precise height adjustment. At the same time, the setting of the guide rod 502 also ensures the stability and straightness of the upper support frame 302 during movement, avoiding maintenance errors caused by offset or shaking.

[0043] See Figure 1 , Figure 2 , Figure 3 The top of the upper support frame 302 is equipped with several fixed support frames 401 and movable clamps 402 for limiting and clamping the motorcycle frame. This provides a stable limiting clamp for the motorcycle frame, ensuring stability and safety during welding or repair. The fixed support frames 401 can firmly support the bottom of the motorcycle frame, preventing it from moving or tilting during welding or repair. At the same time, the movable clamps 402 can be flexibly adjusted according to the shape and size of the motorcycle frame to achieve tight clamping. This limiting clamp design not only improves the stability of the motorcycle frame during repair but also reduces welding defects or repair errors caused by shaking or displacement, thereby improving repair quality and efficiency.

[0044] The implementation principle of this utility model is as follows: First, the sliding plate 2 is slid along the chain slide rail 1 until it reaches the corresponding welding position. Then, the operator moves the connecting arm 703, causing the connecting arm 703 to use the limiting rod 706 as a fulcrum. This causes the two connecting arms 703 to overcome the tension of the tension spring 710 and rotate through the rotating shaft, thereby moving the position of the insert 709 and separating it from the slot 711. At this time, the turntable 6 is rotatable, and the operator can rotate the lower support frame 301 through the turntable 6. The angle of the motorcycle frame with the upper clamping limit can be adjusted. Then, the force on the connecting arm 703 is released, and the movable frame 708 is pulled by the tension spring 710. This allows the connecting arms on both sides and the insert block 709 to gradually return to their initial state. At the same time, the insert block 709 engages with the corresponding slot 711, thereby fixing the position of the lower support frame 301 and the upper support frame 302, improving the welding stability of the motorcycle frame. Through the above operation, the operator can avoid changing positions back and forth, improving the convenience of motorcycle frame welding.
