Description

Technical Field

[0001] This utility model relates to the field of spoke manufacturing technology, specifically to a spoke end tapered sheet rolling device. Background Technology

[0002] The applicant proposed a scheme for forming a tapered structure at the end of a carbon fiber spoke in a previous application. Generally speaking, a tapered section is designed at the end of the spoke, with the outer diameter of this section gradually increasing towards the end of the spoke. A metal component at the spoke end can form a length-direction limiting fit with this tapered section, thereby fixing the metal component to the spoke body. This solves the problem of difficulty in firmly connecting the metal component at the end of the carbon fiber spoke to the carbon fiber spoke body. Furthermore, after assembly onto the rim, the length-direction limiting fit between the tapered section and the metal component effectively ensures that the spoke has good performance in bearing the tensile forces of the rim and hub along its length. (Refer to...) Figure 1 In the process of forming the tapered section, the applicant designed a flexible tapered piece. This tapered piece unfolds into a right-angled triangle on a plane, having two right-angled sides and a hypotenuse. One right-angled side can be attached to the spoke end, with its extension direction aligned with the extension direction of the spoke body. The tapered piece attached to the spoke end is then wound around the spoke end. Due to the triangular shape of the tapered piece, a tapered section with an outer diameter that gradually increases towards the end of the spoke is automatically formed. Before forming the tapered section, the metal parts on the spoke can be fitted onto the spoke body. After the tapered section is formed, the metal parts are then fitted onto the tapered section to create a limiting fit.

[0003] Currently, the rolling of conical sheets is done manually, which results in low production efficiency and high labor costs. Utility Model Content

The openings of the two positioning grooves are both upward and cooperate to form the receiving groove. The spokes placed in the receiving grooves are exposed at both ends of the two receiving seats in the first direction. There are two winding mechanisms arranged along the first direction, which are respectively used to wind the conical pieces attached to the two ends of the spokes in the first direction.

[0009] Technical solution four based on technical solution three: The clamping mechanism is located between the two receiving seats and includes a clamping drive unit and two clamping blocks; the output end of the clamping drive unit is connected to the two clamping blocks and drives the two clamping blocks to move towards or away from each other in a direction perpendicular to the first direction, so as to clamp or release the spokes contained in the receiving groove.

[0010] Technical solution five based on technical solution four: The accommodating mechanism further includes a fixed base, and the two accommodating bases are fixedly connected to the fixed base in an adjustable position along a first direction; the output end of the moving mechanism is connected to the fixed base; and the clamping mechanism is mounted on the fixed base.

[0011] Technical solution six, based on any one of technical solutions one to five, further includes a sliding component, which includes a sliding base, a sliding member, and a sliding drive mechanism; the output end of the sliding drive mechanism is connected to the sliding member and drives the sliding member to slide on the sliding base along a third direction that is perpendicular to both the first direction and the second direction; the sliding member is fixedly connected to the fixing component and drives the fixing component to translate along the third direction.

[0012] Technical solution seven based on technical solution one: Each of the winding mechanism includes two winding components; the two winding components belonging to the same winding mechanism are arranged radially symmetrically along a relative first direction, and the opposing surfaces of the two winding components respectively form a first winding surface and a second winding surface, and the first winding surface and the second winding surface are both planes perpendicular to the radial direction.

[0013] Technical solution eight based on technical solution seven: at least one of the first rolling surface and the second rolling surface has a recessed portion; the recessed portion extends to the edge of the rolling member to make way for the spoke and the tapered piece, and includes a circular groove corresponding to the end shape of the spoke and a flat groove corresponding to the tapered piece.

[0014] Technical solution nine based on technical solution eight: Both the first rolling surface and the second rolling surface are provided with the relief portion, and the two relief portions are arranged diagonally relative to the first axis.

[0015] Technical solution ten based on technical solution one: the rolling component in the rolling mechanism is a roller; each roller rotates around a second axis in a first direction, and the conical piece is wound to the end of the spoke through the circumferential surface of each roller to form the conical segment.

[0016] As can be seen from the above description of this utility model, compared with the prior art, this utility model has the following beneficial effects:

[0017] Technical Solution 1 provides a spoke end tapered blade winding device, which mainly includes a fixing component and a winding component. The fixing component includes a receiving mechanism and a clamping mechanism. The receiving mechanism has a receiving groove for receiving spokes, and when the spoke is placed in the receiving groove, the length direction of the spoke is fixed in a first direction, while the end of the spoke can also protrude from the receiving groove in the first direction. Therefore, by setting the receiving groove, the end of the spoke can be oriented in the correct direction, facilitating subsequent winding of the tapered blade. After the spoke is received in the receiving groove, the clamping mechanism can clamp and fix the spoke, thereby preventing the spoke from rotating or translating due to the influence of the winding component during the tapered blade winding process. In other words, the clamping mechanism further ensures the fixed position and direction of the spoke. By setting the fixing component, the operator can easily place the spoke in the receiving groove during feeding, and then fix the spoke using the clamping mechanism, without needing to adjust and fix the position and direction of the spoke, effectively improving feeding efficiency. The winding assembly includes a rotary drive mechanism and at least one winding mechanism. The winding mechanism can rotate around a first axis under the action of the rotary drive mechanism. The winding mechanism includes a radial drive unit and winding components. The radial drive unit can drive multiple winding components to move closer or further apart to each other radially simultaneously or asynchronously. When these winding components move away from each other, a winding space is formed between them. The end of the spoke can be moved into the winding space. Then, under the action of the radial drive unit, these winding components move closer to each other and contact the end of the spoke. Then, the rotary drive mechanism drives the winding mechanism to rotate, and the winding components also rotate accordingly. During the rotation of the winding components, the winding components apply pressure to the conical plate, causing the conical plate to deform. At the same time, the conical plate is pressed against the end sidewall of the spoke. As the winding mechanism rotates, the winding components rotate around the end of the spoke one or more times until the conical plate is completely attached to the end of the spoke and forms a conical segment. Through the winding assembly, the conical blade can be accurately and efficiently wound into a conical segment surrounding the end of the spoke. The rotary drive mechanism and the winding mechanism in the winding assembly work together to realize the winding action of the conical blade. In addition, the winding assembly also works with the fixing assembly. The fixing assembly can not only facilitate feeding, but also fix the spokes when the winding assembly is working, thereby realizing the automated winding of the conical blade, reducing labor costs and improving production efficiency.

[0018] In technical solution two, the fixed component also includes a moving mechanism, which can drive the receiving mechanism to reciprocate along the second direction. The conical piece attached to the spoke end is unfolded before winding, with only one edge adhering to the spoke end. When the spoke is placed in the receiving groove, the unfolded and laid-out direction of the conical piece may be different. However, during winding, it is essential to ensure that the conical piece contacts the winding component in the correct manner to prevent the conical piece from being squeezed by the winding component and becoming wrinkled or deformed. Such squeezing can also lead to winding failure of the conical piece. Therefore, a moving mechanism is provided. This moving mechanism causes the spoke to move in a second direction as it enters the position to be wound. This movement, in conjunction with the position of the winding component, allows the conical piece to contact the winding component. By setting a specific moving direction, the conical piece can bend in the direction of its winding direction. At this time, the conical piece will always maintain contact with the winding component. Then, the winding components move closer to each other and contact the spoke end. Finally, the winding mechanism is rotated in the correct direction, so that the conical piece is wound around the spoke end in the correct manner.

[0019] In technical solution three, the receiving mechanism includes two receiving seats, each with a positioning groove that cooperates to form the aforementioned receiving groove. By forming the receiving groove through the receiving seats, the spokes can be limited only near the two ends by the receiving groove, while the middle part can be easily removed, and the clamping mechanism can easily fix the spokes. At the same time, two winding mechanisms are provided, which can simultaneously wind the conical pieces at both ends of the spokes, which can further improve the winding efficiency.

[0020] In technical solution four, the clamping mechanism is set between two receiving seats. The clamping drive unit in the clamping mechanism can drive the two clamping blocks to move, thereby clamping or releasing the spokes contained in the receiving groove. The clamping mechanism can hold the spokes after they are contained in the receiving groove, so that the spokes will not rotate or shift during the winding process, thus preventing the winding accuracy from being affected by the loosening of the spokes during the winding process.

[0021] In technical solution five, a fixed seat is also provided. The receiving seat is fixedly attached to the fixed seat in an adjustable position. By adjusting the position of the receiving seat, spokes of different lengths can be adapted. At the same time, the fixed seat can be connected to the moving mechanism and can be installed by the clamping mechanism.

[0022] In technical solution six, a sliding component is also provided. The sliding component can drive the fixed component to move horizontally, so that the fixed component can be loaded at one position, rolled at another position, and then moved to the unloading position, thereby realizing the automated operation of the rolling process. Furthermore, separating the loading, rolling and unloading positions can avoid interference between components and improve the automation level of the rolling equipment.

[0023] In technical solution seven, each winding mechanism includes two winding components. These two winding components are arranged symmetrically in the radial direction relative to the first direction, and the facing surfaces of the two winding components respectively form a first winding surface and a second winding surface, both of which are planes perpendicular to the radial direction. The planar first and second winding surfaces can smoothly adhere to the sidewall of the spoke end during the winding process, avoiding wrinkles or other irregular shapes when the conical sheet is wound. The symmetrical arrangement of the two winding components ensures the uniformity of force on the conical sheet during the winding process, thereby ensuring that the conical sheet can be smoothly wound around the end of the spoke after winding.

[0024] In technical solution eight, a clearance portion is provided on the winding surface of the winding component. The recessed structure of the clearance portion allows the spokes and the tapered blade to be accommodated within it, thereby enabling the first and second winding surfaces of the two winding components to contact each other. This results in a tighter contact between the winding component and the spokes, preventing wrinkles in the tapered blade during the winding process due to excessive gaps between the winding component and the spokes. Simultaneously, the design of the circular groove and the flat groove respectively positions the ends of the spokes and the tapered blade, ensuring that the tapered blade can be accurately wound around the ends of the spokes.

[0025] In technical solution nine, the arrangement of the clearance portion is optimized. The clearance portions on the two winding components are arranged diagonally. When the clearance portion of one winding component contacts the spoke, the winding surface of the other winding component will flatly adhere to the spoke, thus avoiding insufficient contact between the winding component and the spoke due to excessive clearance space. At the same time, since the winding mechanism rotates, it is impossible to determine which of the two winding components is in the correct position during the winding process. Under the action of the lifting mechanism, the conical plate will bend in the winding direction. At this time, it is necessary to ensure that there is a clearance portion in the opposite direction of the bending of the conical plate that contacts the end of the conical plate and the spoke. By arranging the clearance portions on the two winding components diagonally, no matter what position the winding mechanism rotates to, as long as the positional relationship of the two winding components forms a space for the spoke to enter from the second direction, it can be guaranteed that one clearance portion will contact the end of the conical plate and the spoke, so that the conical plate can be accurately wound around the end of the spoke.

[0026] In technical solution ten, the winding component is designed as a roller. During the winding process, the roller also rotates around the second axis. While rotating, its circumferential surface remains in contact with the end of the spoke along the length of the spoke, converting sliding friction into rolling friction. This significantly reduces the friction between the winding component and the conical sheet. The lower friction makes the winding process smoother, reducing wear on the conical sheet caused by excessive friction, improving winding efficiency, and ensuring the integrity of the conical sheet. Compared to the winding component structures in the aforementioned technical solutions, the roller structure is simpler and has lower component costs. Furthermore, as long as the conical sheet correctly contacts the circumferential surface of the roller in the lifting mechanism, the roller can effectively complete the winding process, significantly improving the winding quality of the conical sheet.

[0047] Example 1

[0048] Reference Figure 2 Embodiment 1 of this utility model relates to a spinning device for a spoke end tapered piece 12. The spinning device mainly includes a frame 50, a fixing component 20, a spinning component 30, and a sliding component 40.

[0049] First refer to Figure 1The diagram illustrates the structure of a spoke with tapered plates 12 attached. The spoke as a whole comprises a spoke body 10, connecting caps 11, and tapered plates 12. Two connecting caps 11 are fitted onto the spoke body 10 from both ends, and two tapered plates 12 are attached to the two ends of the spoke body 10. The tapered plates 12 are attached to the spoke body 10 by adhesive. One surface of the tapered plate 12 can be designed to be adhesive, so that during winding, this side surface is the inside, preventing the tapered plate 12 from unraveling after winding. The triangular shape of the conical plate 12 allows it to automatically form a conical segment at the end of the spoke after being rolled. The size and shape of this conical segment are adapted to the size and shape of the through hole inside the connecting cap 11. The connecting cap 11 can be pulled outward to the position of the conical segment, and the conical segment forms a limiting fit between the connecting cap 11 and the spoke body 10 in the length direction, which can effectively improve the tensile force that the connecting cap 11 can withstand when pulled. In this embodiment, the spoke body 10 and the conical plate 12 are made of carbon fiber material, and the connecting cap 11 is made of metal. After the conical plate 12 is wrapped around the spoke body 10, a curing process can be used to solidify the conical plate 12 and the spoke body 10 into one piece, preventing the conical plate 12 from falling off the spoke body 10. After the two are solidified into one piece, the connecting cap 11 can be pulled to the position of the conical segment.

[0050] Reference Figure 2The spoke end conical piece 12 winding device according to Embodiment 1 of this utility model is used to wind the conical piece 12 attached to the spoke end into a conical segment surrounding the spoke end. The fixing assembly 20 includes a receiving mechanism 21 and a clamping mechanism 22. The receiving mechanism 21 has a receiving groove 211 along a first direction, which is adapted to receive the spoke in such a way that the length direction of the spoke is parallel to the first direction, and to expose the end of the spoke with the conical piece 12 attached in the first direction. The clamping mechanism 22 clamps the spoke after it is located in the receiving groove 211 to restrict the spoke from rotating about or translating along the first direction. The winding assembly 30 includes a rotary drive mechanism 31 and at least one winding mechanism 32. The rotary drive mechanism 31... The output end of the unit is connected to the winding mechanism 32 and drives the winding mechanism 32 to rotate around a first axis in a first direction. The winding mechanism 32 includes a radial drive unit 321 and at least two winding members 322. The output end of the radial drive unit 321 is connected to each of the winding members 322 and drives each of the winding members 322 to move towards or away from each other in a radial direction relative to the first direction. When the end of the spoke that is attached to the conical piece 12 is located between each of the winding members 322 of the winding mechanism 32 by the fixing component 20, the radial drive unit 321 drives each of the winding members 322 to move towards each other to contact the end of the spoke, and drives the winding mechanism 32 to rotate by the rotation drive mechanism 31 to wind the conical piece 12 into the conical segment.

[0051] The rolling device also includes a sliding assembly 40, which includes a sliding seat 41, a sliding member 42, and a sliding drive mechanism; the output end of the sliding drive mechanism is connected to the sliding member 42 and drives the sliding member 42 to slide on the sliding seat 41 along a third direction that is perpendicular to both the first direction and the second direction; the sliding member 42 is fixed to the fixing assembly 20 and drives the fixing assembly 20 to translate along the third direction.

[0052] Specifically, refer to Figure 2The fixing component 20 and the winding component 30 of the winding equipment are mounted on a frame 50. The frame 50 includes a main support as the main support body and a platform 51 disposed above the main support. The platform 51 and the main support are connected by a slide rail 52 and a slider 53. Specifically, the main support is a table-shaped component, which can be manufactured using aluminum profiles or other materials. The platform 51 is a flat plate-shaped component, and there are two platforms 51, which are respectively mounted on the main support in the left and right directions. The slide rail 52 and the slider 53 cooperate to form a sliding structure. The slide rail 52 is fixedly mounted on the top of the main support and extends in the left and right directions. The slider 53 is mounted on the slide rail 52 and can slide back and forth along the extension direction of the slide rail 52. The platform 51 is fixed to the slider 53 by bolts, so the platform 51 can slide relative to the main support in the left and right directions. With the cooperation of slide rail 52 and slider 53, both platforms 51 can slide in the left and right directions, thereby adjusting the distance and position of the two platforms 51 in the left and right directions. A drive motor or drive cylinder can be installed on the frame 50 corresponding to each platform 51 to control the movement of the platform 51 automatically and to precisely adjust the position of the platform 51.

[0053] It is necessary to define the directional terms used in this specification and claims. (See reference...) Figures 1 to 8 In this specification, the terms front, back, left, right, up, and down are used to describe directions. The left and right directions correspond to the first directions referred to in this specification and the claims, the up and down directions correspond to the second directions referred to in this specification and the claims, and the front and back directions correspond to the third directions referred to in this specification and the claims.

[0054] The sliding assembly 40 is mounted on the frame 50 and located at the midpoint between the two platforms 51 in the left-right direction. Within the sliding assembly 40, a sliding seat 41 extends in the front-back direction and is fixedly mounted on the frame 50. The aforementioned sliding drive mechanism is installed inside the sliding seat 41. This sliding drive mechanism can be a screw, cylinder, or electric cylinder, and its output end is connected to a sliding member 42. The sliding member 42 and the sliding seat 41 form a sliding engagement, and under the action of the sliding drive mechanism, the sliding member 42 can reciprocate along the extension direction of the sliding seat 41, i.e., the front-back direction. The sliding member 42 has an upward-facing plane, which can be used for mounting the fixed assembly 20. Simultaneously, under the action of the sliding drive mechanism, the sliding member 42 can reciprocate between a pre-set loading station and a winding station. At the loading station, the operator can load spokes into the fixed assembly 20; at the winding station, the spokes located in the fixed assembly 20 can be wound by the winding assembly 30. The sliding component 42 can also move to the unloading station, where the operator can remove the coiled spokes from the fixed component 20. The loading and unloading stations can be in the same location. The sliding component 40 can drive the fixed component 20 to move horizontally, allowing the fixed component 20 to be loaded in one position, coiled in another, and then moved to the unloading position, thereby automating the coiling process. Separating the loading, coiling, and unloading positions avoids interference between components and improves the automation level of the coiling equipment.

[0055] Reference Figures 3 to 5 The fixing component 20 further includes a moving mechanism 23, the output end of which is connected to the receiving mechanism 21 and drives the receiving mechanism 21 to reciprocate along a second direction perpendicular to the first direction; when the end of the spoke that is attached to the conical piece 12 is not located between the winding members 322 in the winding mechanism 32, the moving mechanism 23 is adapted to drive the spoke to move along the second direction and enter between the winding members 322, and during the movement, the conical piece 12 contacts at least one of the winding members 322 and bends toward its winding direction.

[0056] Furthermore, the receiving mechanism 21 includes two receiving seats 212 arranged along a first direction. The two receiving seats 212 are provided with corresponding positioning grooves 213 that are both through the first direction. The openings of the two positioning grooves 213 are both upward and cooperate to form the receiving groove 211. The spokes received in the receiving groove 211 have both ends exposed in the two receiving seats 212 in the first direction. The clamping mechanism 22 is located between the two receiving seats 212 and includes a clamping drive unit 221 and two clamping blocks 222. The output end of the clamping drive unit 221 is connected to the two clamping blocks 222 and drives the two clamping blocks 222 to move towards or away from each other in a direction perpendicular to the first direction, so as to clamp or release the spokes received in the receiving groove 211. The accommodating mechanism 21 further includes a fixed base 214, and the two accommodating bases 212 are fixedly connected to the fixed base 214 in an adjustable position along a first direction; the output end of the moving mechanism 23 is connected to the fixed base 214; and the clamping mechanism 22 is mounted on the fixed base 214.

[0057] Specifically, refer to Figure 5 The fixing assembly 20 includes a receiving mechanism 21, a clamping mechanism 22, and a moving mechanism 23. The receiving mechanism 21 is used to pre-fix the spokes and define their orientation; the clamping mechanism 22 is used to fix the spokes in the fixing assembly 20; and the moving mechanism 23 is used to adjust the position of the spokes in the vertical direction. The above mechanisms will be described in detail below.

[0058] Reference Figure 5 The fixing component 20 includes a fixing base 24 serving as the mounting foundation. The fixing base 24 is a planar plate-shaped component. The moving mechanism 23 is fixedly mounted on the fixing base 24. Simultaneously, the fixing base 24 is bolted to the sliding member 42 of the sliding component 40, allowing the fixing component 20 to reciprocate in the front-back direction under the drive of the sliding component 40. The moving mechanism 23 includes a moving cylinder 231 and a moving connecting block 232. The moving cylinder 231 is bolted to the fixing base 24, and the moving connecting block 232 is fixedly disposed at the output end of the moving cylinder 231 and connected to the receiving mechanism 21. By pressurizing and depressurizing the moving cylinder 231, the moving connecting block 232 can be moved upward or downward, thereby causing the receiving mechanism 21 to move upward or downward. Of course, in other embodiments, the moving cylinder 231 in the moving mechanism 23 can be replaced with other actuators, such as an electric cylinder.

[0059] The receiving mechanism 21 mainly includes a fixed base 214 and a receiving base 212. The fixed base 214 is fixedly connected to the moving connecting block 232 of the moving mechanism 23. A sliding groove 216 is provided on the front side of the fixed base 214 in the left-right direction, and a clearance groove 215 extending in the front-back direction is provided at the middle position of the front side of the fixed base 214 in the left-right direction. The sliding groove 216 is a recessed groove, with its two ends open in the left-right direction and the openings facing upwards. The clearance groove 215 is a through groove, which runs through in the vertical direction and its front end is open. The sliding groove 216 is used to adjust the position of the receiving base 212 in the left-right direction, and the clearance groove 215 is used to make way for the clamping mechanism 22, so that the clamping mechanism 22 can enter the position corresponding to the receiving base 212 to clamp and fix the spokes. Several through holes are also provided on the sliding groove 216 at certain intervals in the left-right direction. These through holes are used for bolts to pass through, so as to form a detachable fixed connection with the receiving base 212.

[0060] There are two receiving seats 212, arranged horizontally on the fixing seat 214. The receiving seat 212 is roughly in the shape of a reclining "L", with its long side extending horizontally. At its bottom, there is a mating protrusion 217 extending horizontally. The size of this mating protrusion 217 matches the size of the sliding groove 216 on the fixing seat 214, allowing the receiving seat 212 to be adjusted horizontally within the limitation of the sliding groove 216 on the fixing seat 214. Simultaneously, a long, narrow through hole extending horizontally is provided on the long side of the receiving seat 212, corresponding to the through hole on the sliding groove 216. When fixing the receiving seat 212, a bolt can be passed through the through hole in the fixing seat 214 and then tightened. When adjusting the horizontal position of the receiving seat 212, the bolt can be loosened, and then the position of the receiving seat 212 can be adjusted. The short side of the receiving seat 212 extends vertically and has a positioning groove 213 that extends horizontally and opens upwards. The two positioning grooves 213 of the two receiving seats 212 are positioned correspondingly and cooperate to form the receiving groove 211 of the receiving mechanism 21. When the spoke is placed into the receiving groove 211, the two ends of the spoke in the length direction are respectively placed in the two positioning grooves 213 of the two receiving seats 212, and the middle part is suspended. The clamping mechanism 22 located in the middle position can clamp and fix the spoke. (Refer to...) Figure 5The positioning groove 213 can be designed with a variable groove width. Specifically, the positioning groove 213 can be divided into two sections with different groove widths along the left-right direction. The groove width of the section near the inner side is greater than that of the section near the outer side. The groove width of the inner side is adapted to the outer diameter of the connecting cap 11, while the groove width of the outer side is adapted to the end outer diameter of the spoke body 10. By designing the groove width of the positioning groove 213 differently, when the spoke is placed on the receiving groove 211, the positions of its two ends are pre-determined within a certain range by the position of the connecting cap 11, thus making it easier to accurately position the spoke in the receiving groove 211.

[0061] The receiving mechanism 21 includes two receiving seats 212, each with a positioning groove 213 that cooperates to form the aforementioned receiving groove 211. By forming the receiving groove 211 through the receiving seats 212, the spokes are limited only near the two ends by the receiving groove 211, allowing for easy removal of the middle portion and facilitating the clamping mechanism 22 to fix the spokes. Simultaneously, two winding mechanisms 32 are provided, which can simultaneously wind the tapered blades 12 at both ends of the spokes, further improving winding efficiency. The receiving seats 212 are adjustablely fixed to the fixed seat 214, allowing for the adaptation of spokes of different lengths. The fixed seat 214 can be connected to the moving mechanism 23 and can be used to mount the clamping mechanism 22.

[0062] The clamping mechanism 22 includes a clamping drive unit 221 and clamping blocks 222. The clamping drive unit 221 can be a cylinder or an electric cylinder, and it includes two output ends. Each of these two output ends is connected to a clamping block 222, and these two output ends can drive the two clamping blocks 222 to move towards or away from each other in the front-back direction. When the two clamping blocks 222 move towards each other, they can clamp and fix the spokes; when they move away from each other, they can release the spokes. (Refer to...) Figure 3 and Figure 4The clamping mechanism 22 is bolted to the fixed base 214 to maintain a relatively fixed position between the clamping block 222 and the fixed base 214. Simultaneously, the clamping block 222 of the clamping mechanism 22 extends upward from the relief groove 215 of the fixed base 214, its vertical position matching the position of the receiving groove 211, so that the spokes can be aligned with the position of the spokes after being received in the receiving groove 211. When fixing the spokes, the spokes can be placed in the receiving groove 211 first, and then the clamping block 222 of the clamping mechanism 22 clamps the spokes, thereby fixing them. The clamping mechanism 22 is positioned between the two receiving seats 212. The clamping drive unit 221 in the clamping mechanism 22 can drive the two clamping blocks 222 to move, thereby clamping or releasing the spokes contained in the receiving groove 211. The clamping mechanism 22 can clamp the spokes after they are contained in the receiving groove 211, so that the spokes will not rotate or shift during the winding process, thus preventing the winding accuracy from being affected by the loosening of the spokes during the winding process.

[0063] Reference Figure 3 and Figure 4 The winding assembly 30 mainly includes a rotary drive mechanism 31 and a winding mechanism 32. In this embodiment, corresponding to the fixed assembly 20 located in the middle position, two winding mechanisms 32 are arranged along the first direction and are respectively used to wind the conical pieces 12 attached to the two ends of the spokes in the first direction. The rotary drive mechanism 31 can be a drive motor, and the number of drive motors corresponds to the two winding mechanisms 32, which can be set to two. Each winding mechanism 32 is connected to the output end of a drive motor, so that the drive motor can drive the winding mechanism 32 to rotate around the first axis. The drive motor is also fixedly mounted on the platform 51 of the frame 50 through a plate-like component, so that the movement of the platform 51 in the left-right direction can drive the motor to adjust its position in the left-right direction.

[0064] Each of the winding mechanisms 32 includes a radial drive unit 321 and at least two winding elements 322. In this embodiment, the number of winding elements 322 is two. The radial drive unit 321 can be a cylinder or an electric cylinder, and it has an output end corresponding to the number of winding elements 322. For example, when the number of winding elements 322 is two, the number of output ends of the radial drive unit 321 is also two. The output ends of the radial drive unit 321 can reciprocate radially relative to the first axis. It can be driven by a conventional cylinder or electric cylinder mechanism, which will not be described in detail here. Each winding mechanism 32 is defined as including two winding elements 322. These two winding elements 322 are arranged radially symmetrically relative to the first direction, and the facing surfaces of the two winding elements 322 respectively form a first winding surface 323 and a second winding surface 324, both of which are planes perpendicular to the radial direction. The planar first and second coiling surfaces 323 and 324 can be flatly attached to the side wall of the spoke end during the coiling process, avoiding wrinkles or other irregular shapes when the conical piece 12 is wound. The symmetrical arrangement of the two coiling components 322 can ensure the uniformity of force on the conical piece 12 during the coiling process, thereby ensuring that the conical piece 12 can be flatly wound on the end of the spoke after coiling.

[0065] In this embodiment, refer to Figure 3 , Figure 4 and Figure 6 Two winding members 322 belonging to the same winding mechanism 32 are arranged radially symmetrically along a first direction, and the facing surfaces of the two winding members 322 respectively form a first winding surface 323 and a second winding surface 324. Both the first winding surface 323 and the second winding surface 324 are planar perpendicular to the radial direction. At least one of the first winding surface 323 and the second winding surface 324 is recessed with a clearance portion 325; the clearance portion 325 extends to the edge of the winding member 322 to make way for the spoke and the tapered plate 12, and includes a circular groove 326 corresponding to the end shape of the spoke and a flat groove 327 corresponding to the tapered plate 12. Both the first winding surface 323 and the second winding surface 324 are provided with the clearance portion 325, and the two clearance portions 325 are arranged diagonally relative to the first axis.

[0066] Specifically, the winding component 322 is generally a rectangular block-shaped member, on which threaded through holes can be provided, and it is connected to the output end of the radial drive unit 321 by bolts or other accessories. A winding surface is formed on one side of the winding component 322, and the winding surfaces on the two winding components 322 face each other and respectively form a first winding surface 323 and a second winding surface 324. Taking the first winding surface 323 as an example, refer to... Figure 6A recessed clearance portion 325 is provided on the first winding surface 323. The clearance portion 325 is located in the lower middle position of the first winding surface 323 and includes a circular groove 326 and a flat groove 327. The circular groove 326 is located in the middle position in the vertical direction and extends to the edge of the winding member 322 in the horizontal direction, which can provide clearance for the end of the spoke. The flat groove 327 is located below the circular groove 326 and is a shallow and flat recessed structure. Its upper edge is the same as the lower edge of the circular groove 326, and the flat groove 327 also extends to the edge of the winding member 322 in the horizontal direction. A winding space 33 is formed between the two winding members 322. The end of the spoke enters the winding space 33, and the end of the spoke body 10 corresponds to the position of the circular groove 326. At the same time, the position of the conical piece 12 corresponds to the position of the flat groove 327, thereby facilitating the winding of the conical piece 12 to the end of the spoke body 10. In addition, a clearance portion 325 is also provided on the second winding surface 324 of the other winding member 322. However, this clearance portion 325 is diagonally arranged with the clearance portion 325 on the first winding surface 323. That is, when the clearance portion 325 on the first winding surface 323 is located in a lower position, the clearance portion 325 on the second winding surface 324 will be located in a higher position. A clearance portion 325 is provided on the winding surface of the winding member 322. The recessed structure of the clearance portion 325 allows the spokes and the tapered plate 12 to be accommodated within the clearance portion 325, thereby allowing the first winding surface 323 and the second winding surface 324 of the two winding members 322 to contact each other. This makes the contact between the winding member 322 and the spokes tighter and prevents the tapered plate 12 from wrinkling during the winding process due to excessive gaps between the winding member 322 and the spokes. At the same time, the design of the circular groove 326 and the flat groove 327 respectively plays a positioning role for the end of the spokes and the tapered plate 12, ensuring that the tapered plate 12 can be accurately wound around the end of the spokes.The clearance portions 325 on the two winding members 322 are arranged diagonally. When the clearance portion 325 of one winding member 322 contacts the spoke, the winding surface of the other winding member 322 will flatly adhere to the spoke, thus avoiding insufficient contact between the winding member 322 and the spoke due to excessive space in the clearance portion 325. At the same time, since the winding mechanism 32 rotates, it is impossible to determine which of the two winding members 322 is in the correct position during the winding process. Under the action of the lifting mechanism, the conical plate 12 will move towards the winding direction. When the cone 12 bends in the opposite direction, it is necessary to ensure that there is a clearance portion 325 in the opposite direction of the bend that contacts the ends of the cone 12 and the spokes. By arranging the clearance portions 325 on the two winding members 322 diagonally, no matter what position the winding mechanism 32 is rotated to, as long as the positional relationship of the two winding members 322 forms a space for the spokes to enter from the second direction, it can be ensured that there is a clearance portion 325 in contact with the ends of the cone 12 and the spokes, so that the cone 12 can be accurately wound around the ends of the spokes.

[0067] During the winding process, the conical piece 12 attached to the spoke end is in an unfolded state before winding, with only one edge attached to the spoke end. When the spoke is placed in the receiving groove 211, the unfolded and laid-out direction of the conical piece 12 may be different. However, during winding, it is essential to ensure that the conical piece 12 can contact the winding member 322 in the correct manner to prevent the conical piece 12 from being squeezed by the winding member 322 and becoming wrinkled or deformed. Such squeezing can also lead to the failure of winding the conical piece 12. Therefore, a moving mechanism 23 is provided to move the spoke in a certain direction. During the process of entering the winding position, there is a movement along the second direction. This movement, in conjunction with the position of the winding member 322, allows the conical piece 12 to contact the winding member 322. By setting a specific direction of movement, the conical piece 12 can bend in the direction of its winding direction. At this time, the conical piece 12 will always maintain contact with the winding member 322. Then, the winding members 322 move closer to each other and contact the end of the spoke. After that, the winding mechanism 32 is rotated in the correct direction, so that the conical piece 12 is wound around the end of the spoke in the correct manner.

[0068] The spoke end tapered piece 12 winding device involved in this embodiment mainly includes a fixing component 20 and a winding component 30. The fixing component 20 includes a receiving mechanism 21 and a clamping mechanism 22. The receiving groove 211 provided on the receiving mechanism 21 can be used to receive the spoke. When the spoke is placed in the receiving groove 211, the length direction of the spoke is fixed in a first direction, and the end of the spoke can also protrude from the receiving groove 211 in the first direction. Therefore, by providing the receiving groove 211, the end of the spoke can be oriented in the correct direction, facilitating subsequent winding of the tapered piece. The spokes are coiled in the tapered plate 12. After the spokes are placed in the receiving groove 211, the clamping mechanism 22 can clamp and fix the spokes, thereby preventing the spokes from rotating or translating due to the influence of the coiling assembly 30 during the coiling process of the tapered plate 12. In other words, the clamping mechanism 22 can further ensure the position and direction of the spokes are fixed. By setting the fixing assembly 20, the operator can easily place the spokes in the receiving groove 211 during feeding, and then fix the spokes by the clamping mechanism 22. There is no need to adjust and fix the position and direction of the spokes, which can effectively improve the feeding efficiency. The winding assembly 30 includes a rotary drive mechanism 31 and at least one winding mechanism 32. The winding mechanism 32 can rotate around a first axis under the action of the rotary drive mechanism 31. The winding mechanism 32 includes a radial drive unit 321 and winding elements 322. The radial drive unit 321 can drive multiple winding elements 322 to move closer or further apart radially simultaneously or asynchronously. When the winding elements 322 move further apart, a winding space 33 is formed between them, and the ends of the spokes can be moved into this winding space 33. Afterwards, the winding elements 322... Under the action of the radial drive unit 321, the 22 parts approach each other and contact the end of the spoke. Then, the rotary drive mechanism 31 drives the winding mechanism 32 to rotate. At the same time, the winding parts 322 also rotate. During the rotation of the winding parts 322, the winding parts 322 apply pressure to the conical piece 12, causing the conical piece 12 to deform. At the same time, the conical piece 12 is pressed against the end side wall of the spoke. As the winding mechanism 32 rotates, the winding parts 322 will rotate around the end of the spoke one or more times until the conical piece 12 is completely attached to the end of the spoke and forms a conical section. Through the winding assembly 30, the conical piece 12 can be accurately and efficiently wound into a conical section surrounding the end of the spoke. The rotary drive mechanism 31 and the winding mechanism 32 in the winding assembly 30 cooperate with each other to realize the winding action of the conical piece 12. In addition, the winding assembly 30 also cooperates with the fixing assembly 20. The fixing assembly 20 can not only facilitate feeding, but also fix the spokes when the winding assembly 30 is working, thereby realizing the automated winding of the conical piece 12, reducing labor costs and improving production efficiency.

[0069] Example 2

[0070] Reference Figure 7 and Figure 8 Example 2 is based on Example 1, but differs from Example 1 in that the winding member 322 in the winding mechanism 32 is set as a roller 328. Each roller 328 rotates about a second axis in a first direction, and the conical piece 12 is wound to the end of the spoke through the circumferential surface 329 of each roller 328 to form the conical segment.

[0071] Specifically, in this embodiment, there are two winding components 322. The output end of the radial drive unit 321 in the winding mechanism 32 can drive the two winding components 322 to move towards or away from each other radially relative to the first axis. When the winding component 322 is configured as a roller 328, the shaft of the roller 328 is directly fixed to the output end of the radial drive unit 321, and the roller 328 can rotate freely around the second axis where its shaft is located. The outer circumference of the roller 328 is a circumferential surface 329 with a certain width.

[0072] During the winding process, the circumferential surface 329 of the roller 328 contacts the end of the spoke. Designing the winding component 322 as a roller 328 allows the roller 328 to rotate around the second axis during winding. As the roller 328 rotates, its circumferential surface 329 remains in contact with the end of the spoke along the length of the spoke, converting sliding friction into rolling friction. This significantly reduces the friction between the winding component 322 and the conical piece 12. The lower friction makes the winding process smoother, reducing wear on the conical piece 12 caused by excessive friction, improving winding efficiency, and ensuring the integrity of the conical piece 12. Compared to the structure of the winding component 322 in the above technical solutions, the roller 328 structure of the winding component 322 is simpler and has lower component costs. Furthermore, as long as the conical piece 12 correctly contacts the circumferential surface 329 of the roller 328 in the lifting mechanism, the roller 328 can complete the winding process effectively, thus improving the winding quality of the conical piece 12. Furthermore, the width of the circumferential surface 329 of the roller 328 can be designed to be greater than the dimension of the conical plate 12 in the left-right direction, thereby ensuring that the circumferential surface 329 of the roller 328 can fully contact the conical plate 12.

[0073] In addition, the roller 328 can be a structure with a hub and a rim. The rim can be made of nylon or rubber with a certain hardness, so that a certain force can be applied to the end of the spoke when in contact, without damaging the conical piece 12 attached to the spoke body 10.

[0074] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model. Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
