[0002] Bicycles are not only traditional means of transportation, but also important equipment for fitness, travel and other sports. Therefore, consumers have higher requirements for the performance, comfort and personalization of bicycles. To meet these needs, bicycle manufacturers need to continuously improve product design and production processes. Electric vehicles, as a convenient means of transportation, are also seeing increasing market demand. Therefore, electric vehicle manufacturers also need to improve the practicality and functionality of electric vehicles. And in the production process of bicycles and electric vehicles, front fork punching is a key process. In the production process of front forks, the processing of hole positions has begun to be taken over by automated equipment.

[0003] Currently, there are some front fork punching devices, including a base, a limiting plate, a fixing component and a punching component. The fixing component and the punching component are both arranged on the base. The position of the ground punching part is limited by setting a limiting plate on the outer periphery of the base, and the front fork is punched by the punching component. However, the above settings allow the position of the front fork to move freely within the area restricted by the limiting plate, resulting in problems such as the front fork deviating from the predetermined punching position, low punching accuracy, and difficult punching. At the same time, if a more stable punching is to be completed, manual intervention is required to manually fix the position of the front fork in order to achieve more accurate punching.

[0004] Therefore, there is an urgent need for a front fork punching device that can solve the problem of the front fork deviating from the predetermined punching position, achieve high-precision punching, and reduce the punching difficulty. Summary of the Invention

It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. Additionally, it should be noted that for the sake of description, only parts related to the present invention are shown in the drawings, rather than all of them.

Moreover, the first feature being "above", "above the top", and "on the top" of the second feature includes that the first feature is directly above and obliquely above the second feature, or simply means that the first feature has a higher horizontal height than the second feature. The first feature being "below", "below the bottom", and "under the bottom" of the second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the first feature has a lower horizontal height than the second feature.

[0044] In the description of this embodiment, the orientation or positional relationships such as "upper", "lower", "left", and "right" are based on the orientation or positional relationships shown in the drawings.

Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0045] The technical solution of the present invention will be further described below in conjunction with the drawings and through specific embodiments.

[0046] This embodiment provides a front fork processing system, which can be applied to fields such as bicycle manufacturing and electric vehicle manufacturing to manufacture the front fork 1. In this embodiment, the front fork processing system includes a front fork assembly device and a front fork punching device. The front fork assembly device can accurately and quickly assemble various front fork 1 components together to form a complete front fork 1. The front fork punching device can accurately punch various mounting holes, positioning holes, etc. at designated positions according to the design requirements, meet the connection and installation requirements between the front fork 1 and other components, thereby realizing the transformation from components to a front fork 1 with complete functions, ensuring the consistency and quality stability of the product, and achieving large-scale production.

[0047] As Figure 1 shown, in this embodiment, the front fork 1 includes a column 11, a bifurcated column 12, and a wheel axle 13. One end of the bifurcated column 12 is connected to the column 11, and the opposite end of the bifurcated column 12 is connected through the wheel axle 13.

[0048] To fix the front fork 1, achieve high-precision punching, and reduce the punching difficulty, as Figure 2As shown, in this embodiment, the front fork punching device includes a base 2, a punching unit 4, and a fixing unit 3. The punching unit 4 is arranged on the base 2 and is used for punching the front fork 1. The fixing unit 3 includes a fixing seat 33, a column limiting component 32, and a wheel axle limiting component 31. The fixing seat 33 is arranged on the base 2, and both the column limiting component 32 and the wheel axle limiting component 31 are arranged on the fixing seat 33. The column 11 can be radially limited along the column 11 through the column limiting component 32, and the wheel axle 13 can be axially limited along the column 11 through the wheel axle limiting component 31. Since the column limiting component 32 restricts the displacement of the front fork 1 in the horizontal direction (i.e., the direction parallel to the fixing seat 33) and the vertical direction (i.e., the direction perpendicular to the fixing seat 33), and the wheel axle limiting component 31 restricts the horizontal direction displacement of the front fork 1, the displacement of the front fork 1 in the two main directions of horizontal and vertical is effectively restricted. This enables the front fork 1 to be stably fixed on the fixing unit 3, reducing the shaking or movement of the front fork 1 during the punching process. After the front fork 1 is stably fixed, when the punching unit 4 punches the front fork 1, the punching position deviation will not be caused by the movement of the front fork 1, thereby improving the punching accuracy; the stable front fork 1 makes it easier for the operator to control the punching device without worrying about the movement of the front fork 1, reducing the operation difficulty. Due to the improvement of punching accuracy and the reduction of punching difficulty, the operator can complete the punching task more quickly and accurately, reducing the time for repeated punching or correction, thereby improving the punching efficiency.

[0049] Preferably, as Figures 2 - 3As shown, in this embodiment, the wheel axle limiting assembly 31 includes a first fixing member 311, a first limiting block 312, and a first driving member 313. The first fixing member 311 is disposed on the fixing base 33. A first limiting groove is formed in the first fixing member 311. At least a part of the wheel axle 13 can be disposed in the first limiting groove. The first limiting block 312 can abut against the wheel axle 13 to limit the wheel axle 13 between the first limiting block 312 and the groove wall of the first limiting groove. The fixed end of the first driving member 313 is connected to the fixing base 33, and the output end of the first driving member 313 is connected to the first limiting block 312. The first driving member 313 is used to drive the first limiting block 312 to approach or move away from the first fixing member 311, so as to limit at least a part of the wheel axle 13 within the first fixing member 311, realizing the limitation of the front fork 1 along the axial direction of the column 11. The first driving member 313 can drive the first limiting block 312 to approach or move away from the first fixing member 311, which is convenient for the insertion and removal of the wheel axle 13. When it is necessary to fix the front fork 1, the first driving member 313 drives the first limiting block 312 to abut against the wheel axle 13 to limit the movement of the wheel axle 13. When it is necessary to remove the front fork 1, the first driving member 313 drives the first limiting block 312 to move away from the first fixing member 311, facilitating the removal of the wheel axle 13. The wheel axle limiting assembly 31 limits the horizontal displacement of the front fork 1. Cooperating with the column limiting assembly 32, the displacement of the front fork 1 in both the horizontal and vertical directions is effectively limited, so that it can be stably fixed on the fixing unit 3, reducing the shaking or movement of the front fork 1 during the drilling process. Optionally, in this embodiment, the opening of the first limiting groove faces the extending direction of the column 11. In other embodiments, the opening of the first limiting groove can face other directions, as long as the wheel axle 13 can be limited.

[0050] Optionally, as Figures 2 - 3 shown, in this embodiment, the first driving member 313 is a linear cylinder. The linear cylinder can provide a driving force in a linear direction, directly pushing the first limiting block 312 to move linearly, so that it can accurately approach or move away from the first fixing member 311, thereby realizing the rapid limitation and release of the wheel axle 13. The structure of the linear cylinder is relatively simple and has no complex transmission mechanism. During long-term use, it is not easy to malfunction, which can ensure the normal operation of the wheel axle limiting assembly 31 and reduce the maintenance cost of the equipment. In other embodiments, the first driving member 313 can also be a hydraulic cylinder or an electric cylinder, etc., as long as it can drive the limiting member to approach or move away from the first fixing member 311.

[0051] Preferably, as Figures 2 - 3As shown, in this embodiment, the column limiting assembly 32 includes a second fixing member 321, a second limiting block 322, and a second driving member 323. The second fixing member 321 is disposed on the fixing base 33. A second limiting groove is formed in the second fixing member 321. At least a part of the column 11 can be disposed within the second fixing member 321. The second limiting block 322 can abut against the column 11 to limit the column 11 between the second limiting block 322 and the groove wall of the second limiting groove. The fixed end of the second driving member 323 is connected to the fixing base 33, and the output end of the second driving member 323 is connected to the second limiting block 322. The second driving member 323 is configured to drive the second limiting block 322 to approach or move away from the second fixing member 321. By providing the second limiting groove, a placement space is provided for the column 11, and the column 11 is preliminarily positioned to be in a preset position, restricting some of its movement freedoms on the horizontal plane. The second limiting block 322 can abut against the column 11 under the action of the second driving member 323, so as to restrict the movement of the column 11 in the vertical direction from above, preventing the column 11 from disengaging from the second fixing member 321, and further restricting the radial displacement of the front fork 1. The provision of the second driving member 323 enables the approach or movement away of the second limiting block 322 from the second fixing member 321 to be flexibly controlled. When the front fork 1 needs to be placed or removed, the second driving member 323 can be used to drive the second limiting block 322 to move away from the second fixing member 321; when drilling, the second limiting block 322 is driven to approach the second fixing member 321 to achieve tight limiting of the column 11. The column limiting assembly 32 restricts the radial displacement of the front fork 1 on the column 11. Cooperating with the wheel axle limiting assembly 31, it effectively restricts the displacement of the front fork 1 in the two main directions of horizontal and vertical, stably fixing the front fork 1, reducing the shaking or movement of the front fork 1 during the drilling process, avoiding deviation of the drilling position caused by the movement of the front fork 1, and improving the accuracy of drilling. Optionally, in this embodiment, the opening of the second limiting groove faces upward. In other embodiments, the opening of the second limiting groove can face other directions, as long as it can achieve radial limiting of the column 11.

[0052] Optionally, as Figures 2 - 3As shown, in this embodiment, the second driving member 323 is a rotary pressing cylinder. The rotary pressing cylinder can precisely control the movement of the second limiting block 322. Through accurate rotation angles and displacements, it can accurately approach or move away from the second fixing member 321, ensuring that the column 11 is accurately limited within the second fixing member 321, improving the accuracy and reliability of the fixation of the front fork 1. The rotary pressing cylinder is also convenient for integration with an automated control system to realize the automated operation of the entire drilling process. The actions of the rotary pressing cylinder can be controlled by programming to cooperate with other components such as the drilling unit 4, improving production efficiency and the consistency of product quality. In other embodiments, the second driving member 323 can also be an electric rotary pressing mechanism or a mechanical link rotary pressing mechanism, etc., as long as it can realize the limitation of the column 11.

[0053] Preferably, as Figures 2 - 3 shown, in this embodiment, the column limiting assembly 32 further includes a radial clamping member 324. The radial clamping member 324 is arranged in the second limiting groove. The radial clamping member 324 is detachably connected to the second fixing member 321, and the radial clamping member 324 can abut against the column 11. Since the radial clamping member 324 is detachably connected to the second fixing member 321, the column limiting assembly 32 can, according to different specifications, shapes or process requirements of the column 11, remove the original radial clamping member 324 and replace it with a radial clamping member 324 of different sizes, structures or materials, so as to realize the adaptation and optimized limitation of different types of columns 11. At the same time, when the radial clamping member 324 is worn, damaged or aged, etc., it can be conveniently detached from the second fixing member 321 and replaced with a new radial clamping member 324 to ensure that the limiting function of the column limiting assembly 32 is always in good condition. By replacing different radial clamping members 324, the column limiting assembly 32 can adapt to front fork 1 columns 11 of various specifications and types, improving the versatility of the drilling equipment and reducing the cost and space occupation required for equipping multiple fixing devices due to different product specifications. Since the radial clamping member 324 can abut against the column 11, the column limiting assembly 32 can limit the movement of the column 11 in the horizontal direction, ensuring that the column 11 is in an accurate position and providing an accurate positioning reference for subsequent drilling operations. By precisely limiting the radial position of the column 11, the shaking and displacement of the front fork 1 during the drilling process are reduced, thereby improving the drilling accuracy, ensuring the accuracy of the drilling position, and reducing the scrap rate caused by drilling position deviation.

[0054] Optionally, in this embodiment, the radial clamping member 324 is an elastic member. The elastic member has soft and elastic properties and can closely fit the outer surface of the column 11. Whether the shape of the column 11 is regular or slightly irregular, it can make full contact with it to achieve good radial limiting. During the drilling process, it can effectively buffer the vibration and impact force generated by drilling, reduce its impact on the column 11 and the entire fixing assembly, and further reduce the shaking of the front fork 1. In other embodiments, the radial clamping member 324 can also be a cast steel member, etc., as long as it can accurately position the front fork 1. Optionally, in this embodiment, the elastic member is made of silica gel material. In other embodiments, the elastic member can also be made of rubber or plastic, etc., as long as it can provide better radial limiting for the front fork 1.

[0055] Specifically, as Figure 2 and Figure 4 shown, in this embodiment, the drilling unit 4 includes a third driving member 41 and a drilling assembly 42. The third driving member 41 is arranged on the base 2, and the drilling assembly 42 is connected to the third driving member 41. The third driving member 41 is used to drive the drilling assembly 42 to move out or into the drilling working position. The third driving member 41 can accurately drive the drilling assembly 42 to move out or into the drilling working position, ensuring the accuracy and consistency of the drilling position, meeting the precision requirements for drilling the front fork 1, and thus improving the product quality and stability. The automated drilling process reduces the manual operation link and saves time. Compared with manual drilling, it can complete the drilling work of a large number of front forks 1 in a shorter time, improving the overall production efficiency. By operating with the drilling unit 4 precisely controlled by the driving member, parameters such as the position and depth of each drilling can be kept highly consistent, avoiding the errors and inconsistencies that may occur in manual drilling, thereby improving the stability and consistency of the product quality and reducing the defective rate.

[0056] Optionally, as Figure 2 and Figure 4As shown in the figure, in this embodiment, the third driving member 41 is a robotic arm. The robotic arm has multiple degrees of freedom and can move and position flexibly in a three-dimensional space. It can accurately send the punching assembly 42 to a specified position for punching according to different shapes, sizes, and punching requirements of the front fork 1. Even for a front fork 1 with a complex shape or irregularly distributed hole positions, the punching task can be accurately completed. The programming flexibility of the robotic arm enables it to quickly adapt to product changes and production process adjustments. When it is necessary to produce different models of front forks 1 or change the punching scheme, only the program of the robotic arm needs to be modified, without the need for large-scale transformation of the hardware equipment, which greatly improves the flexibility of the production line and reduces the production conversion cost. The robotic arm can move and operate with extremely high precision, ensuring the accuracy and consistency of the punching positions, and can stably meet the production requirements. In other embodiments, the third driving member 41 can also be an electric push rod or the like, as long as it can drive the punching assembly 42 to accurately punch the front fork 1.

[0057] Specifically, as Figure 2 and Figure 4 shown in the figure, in this embodiment, the punching assembly 42 includes a connecting member 422 and a plurality of punching members 421 of multiple sizes. The connecting member 422 is connected to the output end of the third driving member 41, and a plurality of punching members 421 are all connected to the connecting member 422. The third driving member 41 can drive any one of the punching members 421 to be in the punching working position. Since the punching assembly 42 includes a plurality of punching members 421 of different sizes and the third driving member 41 can drive any one of the punching members 421 to be in the punching working position, holes of different diameters can be punched on the same front fork 1, meeting the diverse requirements of the front fork 1 in terms of structure, assembly, etc. The plurality of punching members 421 are integrated on a connecting member 422. Driven by the third driving member 41, continuous processing of multiple holes can be achieved with one positioning, reducing the clamping times and positioning time of the front fork 1 during the processing process, and improving the integration degree and production efficiency of the punching operation.

[0058] Optionally, in this embodiment, the punching assembly 42 includes three punching members 421, which are two RAX-271E electric spindles and one RA-151E electric spindle respectively. The two RAX-271E electric spindles and one RA-151E electric spindle are all driven by an EM-3030T motor and can quickly complete the punching operation of the front fork 1. In other embodiments, the punching assembly 42 can include two, four, five or other numbers of punching members 421, as long as it can accurately and efficiently punch the front fork 1.

[0059] Optionally, as Figure 2 and Figure 4As shown, in this embodiment, in the horizontal direction, the output end of the punching member 421 is perpendicular to and faces outward from the output direction of the driving member output end. This enables lateral punching on workpieces with different shapes and structures while enabling vertical punching, expanding the processing range, making the equipment adaptable to the production requirements of more types of products, enhancing the flexibility and versatility of processing, and reducing the need to replace equipment or make large-scale adjustments due to changes in product structure. The punching member 421 facing outward makes it more convenient for operators to install, replace, and perform daily maintenance and repairs on the punching member 421, without the need to disassemble complex components or enter narrow spaces, reducing the operation difficulty and maintenance cost, and improving the operability and maintainability of the equipment.

[0060] Specifically, as Figure 5 shown, in this embodiment, the front fork punching device further includes a housing 5. The housing 5 is connected to the base 2 and covers the fixing unit 3 and the punching unit 4. It can prevent internal components such as the fixing unit 3 and the punching unit 4 from being affected by external factors, avoid damage, wear, or performance degradation of internal components, and extend the service life of the front fork punching device. The housing 5 can isolate the live components, high-speed moving components, etc. inside the equipment from the operators, reducing the risk of safety accidents such as electric shock and being pinched by moving components for the operators. The housing 5 can prevent the dust generated during the punching process from spreading into the surrounding environment, helping to keep the working area clean, reducing dust pollution to the air, and protecting the respiratory system of the operators.

[0061] Preferably, in this embodiment, the front fork punching device further includes a dust suction mechanism. The dust suction mechanism is arranged inside the housing 5 and can collect the dust generated when the front fork punching device is working to ensure the cleanliness of the working environment, reduce the harm of dust to the health of the operators, and at the same time avoid dust accumulation from affecting the normal operation and service life of the front fork punching device, and can also prevent dust from spreading into the external environment of the housing and causing environmental pollution.

[0062] It should be noted here that the dust suction mechanism is a conventional structure in the prior art. Setting the dust suction mechanism in the front fork punching device is a common setting in the art. In this embodiment, any connection method in the prior art can be used to connect with the housing 5 as long as the dust removal function of the space inside the housing 5 is achieved, and no further details will be introduced.

[0063] Preferably, in this embodiment, the front fork punching device further includes a control unit, which is electrically connected to the fixing unit 3 and the punching unit 4 respectively to control the fixing unit 3 and the punching unit 4. The control unit can accurately control the fixing unit 3 to fix the front fork 1 in the accurate position to ensure the punching position accuracy. At the same time, the control unit can accurately control the drill bit of the punching unit 4 to punch holes at the specified position with extremely small deviation, which can meet the high-precision requirements of different front fork 1 models for the punching position. The control unit can control the fixing unit 3 and the punching unit 4 to realize the automatic operation of the whole punching process.

[0064] It should be noted here that the control unit is a conventional structure in the prior art, and setting the control unit in the front fork punching device is a conventional setting in the art. In this embodiment, any control system and communication harness in the prior art can be used, and any connection method in the prior art can be used to connect with the fixing unit 3 and the punching unit 4 respectively, as long as it can realize the fixation of the front fork 1 by the fixing unit 3 and the punching of the front fork 1 by the punching unit 4, and no further specific introduction will be made.

[0065] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, rather than limiting the embodiments of the present invention. For those of ordinary skill in the art, other different forms of changes or variations can be made on the basis of the above description. It is not necessary and impossible to enumerate all the embodiments here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
