Description

Technical Field

[0001] This utility model relates to the field of bicycle technology, and in particular to a body positioning mechanism for assembling a bicycle flywheel. Background Technology

[0002] The body positioning mechanism used in bicycle freewheel assembly is typically used to precisely position the freewheel body during the production, assembly, or repair of the freewheel, ensuring proper alignment between the freewheel and other components. The goal of this positioning mechanism is to improve production efficiency, reduce assembly errors, and guarantee the accuracy of the various components, such as the sprockets, during assembly.

[0003] The existing assembly mechanism has an inefficient positioning process, which may cause jamming between components and make it impossible to ensure the accurate position of the flywheel body during assembly. This may lead to assembly errors between the flywheel body and other components, affecting assembly quality and product performance. The positioning and assembly process of the flywheel body requires more time and steps, reducing production efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a body positioning mechanism for bicycle flywheel assembly, which can ensure that the flywheel body is accurately positioned during the assembly process, the positioning process is smooth, and assembly problems caused by positioning errors are avoided.

[0005] To solve the above-mentioned technical problems, this utility model provides a body positioning mechanism for bicycle flywheel assembly, including a lifting mechanism and a rotating platform disposed on one side of the lifting mechanism. The rotating platform is provided with multiple rotating mechanisms, and each rotating mechanism is provided with a gripper mechanism. A positioning and alignment mechanism is slidably disposed on the lifting mechanism. The positioning and alignment mechanism includes a positioning support plate, and the positioning support plate is provided with a positioning port for the flywheel body to pass through. A movable groove is provided on one side of the positioning port, and a positioning block that can move up and down is provided in the movable groove. The positioning block is provided with an upper positioning arc surface and a lower positioning arc surface. A step portion corresponding to the flywheel body is provided between the upper positioning arc surface and the lower positioning arc surface. A fixing block is provided on the positioning support plate, and an elastic element is provided between the fixing block and the positioning block.

[0006] The positioning and alignment mechanism includes a positioning bracket, and the positioning support plate is fixed on the positioning bracket.

[0007] A movable rod is fixed on the positioning block, and an avoidance groove is provided on the fixed block, with the movable rod disposed within the avoidance groove.

[0008] The positioning bracket is equipped with a positioning sensor for sensing the position of the movable rod.

[0009] The rotating platform is equipped with a rotary cylinder at its bottom to drive its rotation.

[0010] The lifting mechanism includes a lifting bracket, a vertical slide rail on the lifting bracket, a positioning bracket slidably mounted on the vertical slide rail, and a lifting cylinder for driving the positioning bracket to move on the lifting bracket.

[0011] The rotating mechanism includes a transmission component mounted on a rotating platform, a rotating motor located below the transmission component, and a gripper mechanism located above the transmission component.

[0012] The gripper mechanism includes a gripper body, a gripping slide rail on the gripper body, a gripping arm on the gripping slide rail, and a gripper head on the gripping arm.

[0013] The clamping slide rail, clamping arm, and claw head are provided in at least 3 sets.

[0014] The gripper body is equipped with a pressure regulating valve for adjusting the tightness of the gripping arm.

[0015] In use, the flywheel body is first placed on the gripper mechanism, and the position of the gripping arm is adjusted so that the gripper head firmly grasps the flywheel body. The rotary cylinder drives the rotary platform to rotate, so that the gripper mechanism is directly below the positioning and alignment mechanism. The lifting mechanism drives the positioning and alignment mechanism to descend, so that the flywheel body passes through the positioning port. Since the flywheel body has multiple protruding teeth, there is a notch between the protruding teeth. These protruding teeth first abut against the step. As the flywheel body rotates, when the notch corresponds to the lower positioning arc surface, the elastic element drives the positioning block to move downward, so that it is just locked on the notch. At the same time, the movable rod moves downward, and the positioning sensor feeds back to the system, and the positioning is completed.

[0016] The beneficial effects of this utility model are:

[0017] This invention ensures accurate and smooth positioning of the flywheel body during assembly, avoiding assembly problems caused by positioning errors.

[0018] By monitoring the position of the movable rod in real time with the positioning sensor and feeding it back to the system, precise control can be achieved to ensure that the positioning block is accurately positioned.

[0019] The gripper mechanism, with its multiple sets of gripping slides, gripping arms, and gripper heads, can adapt to flywheel bodies of different sizes and shapes, exhibiting strong versatility and flexibility. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0029] according to Figures 1 to 6As shown, this utility model discloses a body positioning mechanism for assembling a bicycle freewheel, comprising a lifting mechanism 1 and a rotating platform 2 located on one side of the lifting mechanism 1. The rotating platform 2 is equipped with multiple rotating mechanisms 3, each fitted with a gripper mechanism 4 to firmly clamp the freewheel body, ensuring that the freewheel does not shift or rotate during the assembly process and guaranteeing assembly accuracy. The design of the lifting mechanism 1 allows the positioning and alignment mechanism 5 to slide and adjust along the lifting bracket 20, thereby achieving precise vertical positioning of the freewheel body. The positioning and alignment mechanism 5 includes a positioning support plate 6, which has a positioning opening 7 for the freewheel body to pass through. A movable groove 8 is provided on one side of the positioning opening 7, and a vertically movable positioning block 9 is installed within the movable groove 8. The positioning block 9 has two arc-shaped structures: an upper positioning arc surface 10 and a lower positioning arc surface 11, which mate with a notch on the freewheel body, forming a step 12 between them. This step 12 can abut against the protruding teeth on the freewheel body. The positioning support plate 6 is also equipped with a fixing block 13. The function of the fixing block 13 is to firmly fix the positioning block 9 in the predetermined position, ensuring that the entire positioning system will not be displaced due to vibration or external force during operation. An elastic element 14 is provided between the positioning block 9 and the fixing block 13 to drive the positioning block 9 to move downward.

[0030] The positioning and alignment mechanism 5 includes a positioning bracket 15, a positioning support plate 6 fixed on the positioning bracket 15, and a movable rod 16 fixed on the positioning block 9. To ensure that the movable rod 16 moves without obstruction, a clearance groove 17 is provided on the fixed block 13, allowing the movable rod 16 to slide freely within the clearance groove 17, thereby avoiding interference or friction with other components. A position sensor 18 is also provided on the positioning bracket 15. The function of this sensor is to sense the position of the movable rod 16 in real time, ensuring that it accurately reaches its designated position within a specified stroke, avoiding assembly errors caused by positional deviations. When the movable rod 16 reaches the predetermined position, the sensor will send a signal to prompt the system or operator to proceed with the next step.

[0031] The bottom of the rotating platform 2 is equipped with a rotating cylinder 19 to drive its rotation, thereby switching the clamping mechanism and improving work efficiency.

[0032] The lifting mechanism 1 includes a lifting bracket 20, a vertical slide rail 21 on the lifting bracket 20, a positioning bracket 15 slidably mounted on the vertical slide rail 21, and a lifting cylinder 22 for driving the positioning bracket 15 to move on the lifting bracket 20.

[0033] The rotating mechanism 3 includes a transmission assembly 23 mounted on a rotating platform 2, a rotary motor 24 positioned below the transmission assembly 23, and a gripper mechanism 4 positioned above the transmission assembly 23. The transmission assembly 23 transmits the power of the rotary motor 24 to the gripper mechanism 4, enabling the gripper mechanism 4 to rotate smoothly.

[0034] The gripper mechanism 4 includes a gripper body 25, a gripping slide rail 26 on the gripper body 25, a gripping arm 27 on the gripping slide rail 26, and a gripper head 28 on the gripping arm 27. There are at least three sets of gripping slide rails 26, gripping arms 27, and gripper heads 28. During the gripping process, the gripper head 28 on each set of gripping arms 27 cooperates with the flywheel body to ensure that all parts of the flywheel are evenly gripped. The multiple sets of gripper structures not only enhance the stability of the gripping but also increase the distribution of the gripping surface and gripping force, making the entire gripping process more precise and efficient.

[0035] according to Figure 7 As shown, the gripper body 25 is equipped with a pressure regulating valve 29. The function of the pressure regulating valve 29 is to precisely adjust the tightness of the gripping arm 27 by controlling the air pressure. The pressure regulating valve 29 can adjust the clamping force of the gripping arm 27 in real time, thereby ensuring that the flywheel body is firmly fixed, while avoiding damage or deformation of the flywheel body due to excessive clamping force. This adjustment method allows the gripper to automatically adjust the clamping pressure according to the specific size, shape and assembly requirements of the flywheel body, ensuring that each assembly is carried out under the most suitable conditions. After the flywheel body is positioned, the pressure regulating valve 29 will drive the gripping arm 27 to slightly loosen the flywheel body by fine-tuning the air pressure. In this way, the gripping arm 27 can still maintain a moderate clamping on the flywheel body, but will not apply excessive pressure, avoiding the flywheel continuing to rotate and causing damage or other adverse effects to the positioning and alignment mechanism 5, and also facilitating subsequent assembly operations.

[0036] When using this invention, the flywheel body is first placed on the gripper mechanism 4, and the position of the gripping arm 27 is adjusted so that the claw head 28 firmly grips the flywheel body. The rotary cylinder 19 drives the rotary platform 2 to rotate, so that the gripper mechanism 4 is directly below the positioning and alignment mechanism 5. The lifting mechanism 1 drives the positioning and alignment mechanism 5 to descend, so that the flywheel body passes through the positioning port 7. Since the flywheel body has multiple protruding teeth, there is a notch between the protruding teeth. These protruding teeth first abut against the step part 12. As the flywheel body rotates, when the notch corresponds to the lower positioning arc surface 11, the elastic element 14 drives the positioning block 9 to move downward, so that it is just locked on the notch. At the same time, the movable rod 16 moves downward, and the positioning sensor 18 feeds back to the system, and the positioning is completed.

[0037] The beneficial effects of this utility model are:

[0038] This invention ensures accurate and smooth positioning of the flywheel body during assembly, avoiding assembly problems caused by positioning errors.

[0039] By monitoring the position of the movable rod in real time with the positioning sensor and feeding it back to the system, precise control can be achieved to ensure that the positioning block is accurately positioned.

[0040] The gripper mechanism, with its multiple sets of gripping slides, gripping arms, and gripper heads, can adapt to flywheel bodies of different sizes and shapes, exhibiting strong versatility and flexibility.

[0041] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
