Description

Technical Field

[0001] The invention relates to the technical field of spoke manufacturing, and in particular to a spoke end conical sheet rolling and rolling device. Background Art

[0002] In the prior application, the applicant proposed a solution for forming a tapered structure at the end of a carbon fiber spoke. Generally speaking, a tapered section is designed at the end of the spoke, and the outer diameter of the tapered section gradually increases along the length direction of the spoke toward the end of the spoke. The metal piece provided at the end of the spoke can form a limit fit with the tapered section in the length direction, thereby fixing the metal piece to the spoke body, solving the problem that the metal piece at the end of the carbon fiber spoke is difficult to combine and fix with the carbon fiber spoke body. After being assembled on the rim, the limit fit between the tapered section and the metal piece in the length direction can effectively ensure that the spoke has a good performance in withstanding the tension of the rim and the hub in the length direction. Figure 1 In the process of forming the tapered section, the applicant designed a flexible tapered sheet, which is unfolded on a plane into a right triangle, with two right-angled sides and a hypotenuse, wherein the right-angled side can be attached to the spoke end and the extension direction of the right-angled side is consistent with the extension direction of the spoke body, and then the tapered sheet attached to the spoke end is wound on the spoke end. Due to the triangular shape of the tapered sheet itself, a tapered section with an outer diameter gradually increasing toward the end of the spoke end is automatically formed at the spoke end. Before forming the tapered section, the metal piece on the spoke can be inserted into the spoke body first, and after the tapered section is formed, the metal piece can be inserted into the tapered section to form a limited fit between the two.

[0003] Currently, the rolling and rolling of cone sheets is all done manually, which has the problems of low production efficiency and high labor cost. Summary of the invention

[0011] Technical solution 6 based on any one of technical solutions 1 to 5: also includes a sliding component, which includes a sliding seat, 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 seat along a third direction that is perpendicular to the first direction and the second direction; the sliding member is fixedly connected to the fixed component and drives the fixed component to translate along the third direction.

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

[0013] Technical Solution 8 based on Technical Solution 7: At least one of the depressions in the first rolling surface and the second rolling surface is provided with a yield portion; the yield portion extends to the edge of the rolling member to give way to the spokes and the conical piece, and includes a circular groove corresponding to the end shape of the spoke and a flat groove corresponding to the conical piece.

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

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

[0016] It can be seen from the above description of the present invention that, compared with the prior art, the present invention has the following beneficial effects:

[0017] Technical solution 1 provides a spoke end conical sheet rolling and rolling device, which mainly includes a fixing component and a rolling and rolling component; wherein the fixing component includes a accommodating mechanism and a clamping mechanism, the accommodating groove provided on the accommodating mechanism can be used to accommodate the spoke, and when the spoke is placed in the accommodating groove, the length direction of the spoke will be fixed to a first direction, and the end of the spoke can also be exposed from the accommodating groove in the first direction. Therefore, by setting the accommodating groove, the end of the spoke can be directed to the correct direction to facilitate the subsequent rolling and rolling of the conical sheet; after the spoke is accommodated in the accommodating groove, the clamping mechanism can clamp and fix the spoke, thereby preventing the spoke from rotating or translating due to the influence of the rolling and rolling component during the rolling and rolling process of the conical sheet, that is, the position and direction of the spoke can be further fixed by the clamping mechanism; by setting the fixing component, the operator can easily place the spoke in the accommodating groove when loading, and then fix the spoke through the clamping mechanism, without the need to adjust and fix the position and direction of the spoke, which can effectively improve the loading 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. At the same time, the winding mechanism includes a radial drive unit and a winding member. The radial drive unit can drive multiple winding members to approach or move away from each other radially simultaneously or asynchronously. When these winding members move away from each other, a winding space will be formed between these winding members, and the end of the spoke can be moved to the winding space. After that, these winding members approach each other and contact the end of the spoke under the action of the radial drive unit. After that, the rotary drive mechanism drives the winding mechanism to rotate, and the winding members will also rotate accordingly. During the rotation of the winding member, the winding member will apply pressure to the conical piece to deform the conical piece, and at the same time, the conical piece will be pressed against the end side wall of the spoke. As the winding mechanism rotates, the winding member will rotate around the end of the spoke for one or more circles until the conical piece is completely attached to the end of the spoke and forms a conical section. Through the rolling and coiling assembly, the conical sheet can be accurately and efficiently wound into a conical section surrounding the end of the spoke, and the rotating drive mechanism and the rolling and coiling mechanism in the rolling and coiling assembly cooperate with each other to realize the rolling and coiling action of the conical sheet; in addition, the rolling and coiling assembly also cooperates with the fixing assembly, and the fixing assembly not only facilitates loading, but also fixes the spokes when the rolling and coiling assembly is working, thereby realizing the automatic rolling of the conical sheet, reducing labor costs and improving production efficiency.

[0018] In the second technical solution, the fixing assembly further includes a moving mechanism, through which the accommodating mechanism can be driven to move back and forth along the second direction. Among them, the conical sheet attached to the end of the spoke is in an unfolded state before rolling, and only one edge of it is attached to the end of the spoke. When the spoke is placed in the accommodating groove, the unfolding and laying direction of the conical sheet may be in different directions, but during rolling, it must be ensured that the conical sheet can contact the rolling member in a correct way to prevent the conical sheet from being squeezed by the rolling member and wrinkled or deformed. At the same time, such squeezing will also cause the failure of rolling of the conical sheet; therefore, a moving mechanism is provided, and the moving mechanism is used to make the spoke move along the second direction during the process of entering the position to be rolled, and this action is coordinated with the position of the rolling member so that the conical sheet can contact the rolling member, and by setting a certain moving direction, the conical sheet can be bent in the direction toward its winding direction, and at this time the conical sheet will always keep in contact with the rolling member, and then the rolling members will approach each other and contact the end of the spoke, and then the rolling mechanism will be rotated in the correct direction, so that the conical sheet can be wound on the end of the spoke in a correct way.

[0019] In technical solution three, the accommodating mechanism includes two accommodating seats. The positioning grooves respectively arranged on the two accommodating seats cooperate to form the above-mentioned accommodating grooves. By forming the accommodating grooves through the accommodating seats, the spokes can be limited by the accommodating grooves only near the two ends, and the middle part can be easily taken, and the clamping mechanism can be convenient for fixing the spokes; two rolling mechanisms are also arranged, and these two rolling mechanisms can roll the conical pieces at both ends of the spokes at the same time, which can further improve the rolling efficiency.

[0020] In technical solution four, the clamping mechanism is arranged between the two accommodating seats. The clamping drive unit in the clamping mechanism can drive the two clamping blocks to move, thereby clamping or loosening the spokes accommodated in the accommodating grooves. The clamping mechanism can clamp the spokes after they are accommodated in the accommodating grooves, so that the spokes will not rotate or translate during the winding process, thereby 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, and the accommodating seat is fixedly connected to the fixed seat in an adjustable position. By adjusting the position of the accommodating 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 with the clamping mechanism.

[0022] In technical solution six, a sliding component is also provided, through which the fixed component can be driven to translate, so that the fixed component can load materials at one position, roll them at another position, and then move to the unloading position, thereby realizing the automation of the rolling process, and separating the loading, rolling and unloading positions to avoid mutual interference between components, which is beneficial to improving the automation level of the rolling equipment.

[0023] In the technical solution seven, it is defined that each winding mechanism includes two winding members, which are arranged symmetrically along the radial direction relative to the first direction, and the surfaces of the two winding members facing each other form a first winding surface and a second winding surface, respectively, and both are planes perpendicular to the radial direction. The planar first winding surface and the second winding surface can be flatly attached to the side wall of the spoke end during the winding process to avoid wrinkles or other irregular shapes when the conical sheet is wound. The symmetrical arrangement of the two winding members can ensure the uniformity of the force on the conical sheet during the winding process, thereby ensuring that the conical sheet can be flatly wound on the spoke end after winding.

[0024] In the eighth technical solution, a clearance portion is provided on the rolling surface of the rolling element. The recessed structure of the clearance portion allows the spokes and the conical piece to be accommodated in the clearance portion, so that the first rolling surface and the second rolling surface of the two rolling elements can contact each other, making the rolling element contact the spoke more closely, avoiding the conical piece from wrinkling during the rolling process due to the excessive gap between the rolling element and the spoke. At the same time, the design of the round groove and the flat groove respectively positions the end of the spoke and the conical piece, ensuring that the conical piece can be accurately wound on the end of the spoke.

[0025] In technical solution nine, the arrangement of the yielding parts is optimized, and the yielding parts on the two winding members are arranged diagonally. When the yielding part of one winding member contacts the spoke, the winding surface of the other winding member will fit smoothly on the spoke, thereby avoiding the winding member and the spoke from not being in close contact due to the large space of the yielding part. At the same time, since the winding mechanism will rotate, it is impossible to determine which of the two winding members is in the correct position during the winding process, and under the action of the lifting mechanism, the conical piece will bend in the winding direction. At this time, it is necessary to ensure that there is a yielding part in contact with the end of the conical piece and the spoke in the opposite direction of the bending of the conical piece. By arranging the yielding parts on the two winding members diagonally, no matter what position the winding mechanism rotates to, as long as the positional relationship of the two winding members is to form a space for the spoke to enter from the second direction, it can be ensured that there is a yielding part in contact with the end of the conical piece and the spoke, so that the conical piece can be accurately wound around the end of the spoke.

[0026] In the technical solution 10, the winding member is designed as a roller. During the winding process, the roller will also rotate around the second axis. While the roller rotates, its circumferential surface will always keep in contact with the end of the spoke around the length direction of the spoke, and the sliding friction can be converted into rolling friction, which significantly reduces the friction between the winding member and the cone. The smaller friction makes the winding process smoother, reduces the wear of the cone caused by excessive friction, improves the winding efficiency, and ensures the integrity of the cone. Compared with the structure of the winding member in the above technical solution, the winding member with a roller structure is simpler in structure and has a low cost of parts. At the same time, as long as the cone can correctly contact the circumferential surface of the roller in the lifting mechanism, the roller can complete the winding process well, which can effectively improve the quality of the cone.

[0049] First refer to Figure 1 , which shows the structure of the spoke with the conical piece 12 attached. The spoke as a whole includes a spoke body 10, a connecting cap 11 and a conical piece 12, wherein the connecting cap 11 is two in number and is respectively sleeved on the spoke body 10 from both ends, and the conical piece 12 is two in number and is respectively attached to the two ends of the spoke body 10. The conical piece 12 can be attached to the spoke body 10 by gluing, and one side surface of the conical piece 12 itself can be designed to be sticky, so that the side surface is used as the inner side during winding, so that the conical piece 12 will not fall apart after rolling. The triangular shape of the conical piece 12 can automatically form a conical section at the end of the spoke after the conical piece 12 is rolled. The size and shape of the conical section are adapted to the size and shape of the inner through hole of the connecting cap 11. The connecting cap 11 can be pulled outward to the position of the conical section, and the connecting cap 11 and the spoke body 10 are limited in the length direction through the conical section, which can effectively increase the tensile force that the connecting cap 11 can withstand when pulling the connecting cap 11. In this embodiment, the spoke body 10 and the conical piece 12 are made of carbon fiber material, and the connecting cap 11 is made of metal. After the conical piece 12 is wrapped around the spoke body 10, the conical piece 12 and the spoke body 10 can be solidified into one through a curing process to prevent the conical piece 12 from falling off the spoke body 10. After the two are solidified into one, the connecting cap 11 can be pulled to the position of the conical section.

The frame 50 includes a main support as a supporting body, and a platform 51 arranged 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 made of aluminum profiles or other materials. The platform 51 is a flat plate-shaped component. There are two platforms 51, which are respectively installed on the main support in the left and right directions. The slide rail 52 and the slider 53 cooperate to form a sliding structure.

By pressurizing and depressurizing the moving cylinder 231, the moving connection block 232 can be driven to move up or down, thereby driving the accommodating mechanism 21 to move up and down. Of course, in other embodiments, the moving cylinder 231 in the moving mechanism 23 can be replaced by other drivers, such as electric cylinders.

[0059] The accommodating mechanism 21 mainly includes a fixed seat 214 and an accommodating seat 212. The fixed seat 214 is fixedly connected to the moving connecting block 232 of the moving mechanism 23. A sliding groove 216 is provided in the left-right direction at the front side of the fixed seat 214. At the same time, a clearance groove 215 extending in the front-back direction is provided in the middle position of the left-right direction of the front side of the fixed seat 214. The sliding groove 216 is a sunken groove, and its two ends in the left-right direction are open and the opening faces upward. The clearance groove 215 is a through groove, which is through in the up-down direction and has an open front end. The sliding groove 216 is used for the accommodating seat 212 to adjust its position 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 accommodating seat 212 to clamp and fix the spokes. A plurality of through holes are also provided on the sliding groove 216 at a certain distance in the left-right direction, and these through holes are used for bolts to pass through to form a detachable fixed matching relationship with the accommodating seat 212.

[0060] There are two accommodating seats 212, and the two accommodating seats 212 are arranged on the fixing seat 214 in the left-right direction. The shape of the accommodating seat 212 is roughly an inverted "L" shape, and the long side of the accommodating seat 212 extends in the left-right direction. A matching protrusion 217 extending in the left-right direction is provided at the bottom. The size of the matching protrusion 217 is adapted to the size of the sliding groove 216 on the fixing seat 214, so that the accommodating seat 212 can be adjusted in the left-right direction under the limit of the sliding groove 216 of the fixing seat 214; at the same time, a long strip-shaped through hole extending in the left-right direction is also provided on the long side of the accommodating seat 212 corresponding to the through hole on the sliding groove 216. When fixing the accommodating seat 212, the bolt can be passed through the through hole of the fixing seat 214 and penetrated through the through hole on the fixing seat 214, and then the bolt can be tightened. When adjusting the position of the accommodating seat 212 in the left-right direction, the bolt can be loosened, and then the position of the accommodating seat 212 can be adjusted. The short side of the receiving seat 212 extends in the up-down direction and is provided with a positioning groove 213 that runs through in the left-right direction and opens upward. The two positioning grooves 213 of the two receiving seats 212 correspond to each other and cooperate to form the receiving groove 211 of the receiving mechanism 21. When the spoke is placed in the receiving groove 211, the two ends of the spoke in the length direction will be placed in the two positioning grooves 213 of the two receiving seats 212 respectively, and the middle part will be suspended, and the clamping mechanism 22 located in the middle position can clamp and fix the spoke. Figure 5, the positioning groove 213 can be designed to have a structure with a variable groove width. Specifically, the positioning groove 213 can be divided into two sections with different groove widths along the left and right directions, wherein the groove width of the portion close to the inner side is greater than the groove width of the portion close to the outer side, and the groove width of the inner side is adapted to the outer diameter of the connecting cap 11, and the groove width of the outer side is adapted to the outer diameter of the end 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 will be pre-determined by the position of the connecting cap 11 to a rough range, thereby making it easier to position the spoke in the receiving groove 211 at an accurate position.

[0061] The accommodating mechanism 21 includes two accommodating seats 212. The positioning grooves 213 respectively arranged on the two accommodating seats 212 cooperate to form the above-mentioned accommodating grooves 211. By forming the accommodating grooves 211 through the accommodating seats 212, the spokes can be limited by the accommodating grooves 211 only at the positions close to the two ends, and the middle part can be conveniently taken, and the clamping mechanism 22 can be conveniently fixed to the spokes; at the same time, two rolling mechanisms 32 are arranged, and the two rolling mechanisms 32 can roll the conical pieces 12 at the two ends of the spokes at the same time, which can further improve the rolling efficiency. The accommodating seat 212 can be fixedly connected to the fixing seat 214 with adjustable position. By adjusting the position of the accommodating seat 212, spokes of different lengths can be adapted. At the same time, the fixing seat 214 can be connected to the moving mechanism 23 and can be installed by the clamping mechanism 22.

[0062] The clamping mechanism 22 includes a clamping drive unit 221 and a clamping block 222, wherein the clamping drive unit 221 can be a pneumatic cylinder or an electric cylinder, and includes two output ends, which are respectively connected to a clamping block 222, and the two output ends can drive the two clamping blocks 222 to move toward or away from each other in the front-rear direction. When the two clamping blocks 222 move toward each other, they can clamp and fix the spokes, and when they move away from each other, they can release the spokes. Figure 3 and Figure 4The clamping mechanism 22 is fixedly mounted on the fixing seat 214 by bolts to keep the clamping block 222 and the fixing seat 214 relatively fixed in position, and the clamping block 222 of the clamping mechanism 22 extends upward from the position of the clearance groove 215 of the fixing seat 214, and its position in the up-down direction is adapted to the position of the receiving groove 211, so that it can be adapted to the position of the spoke after the spoke is received in the receiving groove 211. When fixing the spoke, the spoke can be placed in the receiving groove 211 first, and then the clamping block 222 of the clamping mechanism 22 clamps the spoke, so that the spoke is fixed. The clamping mechanism 22 is arranged between the two accommodating seats 212. The clamping drive unit 221 in the clamping mechanism 22 can drive the two clamping blocks 222 to move, thereby clamping or loosening the spokes accommodated in the accommodating grooves 211. The clamping mechanism 22 can clamp the spokes after they are accommodated in the accommodating grooves 211, so that the spokes will not rotate or translate during the winding process, thereby preventing the winding accuracy from being affected by the looseness of the spokes during the winding process.

[0063] Reference Figure 3 and Figure 4 The winding assembly 30 mainly includes a rotation 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 sheets 12 attached to the two ends of the spokes in the first direction. Among them, the rotation drive mechanism 31 can be a driving motor, and the number of driving motors can be set to two corresponding to the two winding mechanisms 32. Each winding mechanism 32 is connected to the output end of a driving motor, so that the winding mechanism 32 can be driven to rotate around the first axis by the driving motor. The driving motor is also fixedly mounted on the platform 51 of the frame 50 through a plate-like component, so that the platform 51 can be moved in the left and right directions to drive itself to adjust its position in the left and right directions.

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

[0065] In this embodiment, refer to Figure 3 , Figure 4 and Figure 6 The two rolling members 322 belonging to the same rolling mechanism 32 are arranged symmetrically along the radial direction relative to the first direction, and the surfaces facing each other of the two rolling members 322 form a first rolling surface 323 and a second rolling surface 324, respectively. The first rolling surface 323 and the second rolling surface 324 are both planes perpendicular to the radial direction. At least one of the first rolling surface 323 and the second rolling surface 324 is recessed with a yielding portion 325; the yielding portion 325 extends to the edge of the rolling member 322 to yield the spokes and the conical piece 12, and includes a circular groove 326 corresponding to the end shape of the spoke and a flat groove 327 corresponding to the conical piece 12. The yielding portion 325 is provided in both the first rolling surface 323 and the second rolling surface 324, and the two yielding portions 325 of the two are arranged diagonally relative to the first axis.

[0066] Specifically, the rolling element 322 is a roughly rectangular block-shaped component, on which a threaded through hole may be provided, and connected to the output end of the radial drive unit 321 through bolts or other accessories. A rolling surface is formed on one side of the rolling element 322, and the rolling surfaces on the two rolling elements 322 are opposite to each other and form a first rolling surface 323 and a second rolling surface 324 respectively. Figure 6A recessed portion 325 is provided on the first rolling surface 323. The recessed portion 325 is located in the middle and lower part of the first rolling surface 323 and includes a circular groove 326 and a flat groove 327. The circular groove 326 is located in the middle of the vertical direction and extends to the edge of the rolling element 322 in the left-right direction, so as to make way for the end of the spoke. The flat groove 327 is provided below the circular groove 326 and is a shallow and flat recessed structure. The upper edge of the recessed portion is the same edge as the lower edge of the circular groove 326, and the flat groove 327 also extends to the edge of the rolling element 322 in the left-right direction. A winding space 33 is formed between the two winding members 322, and 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, and the position of the conical piece 12 corresponds to the position of the flat groove 327, so that the conical piece 12 is conveniently wound to the end of the spoke body 10. In addition, a yielding portion 325 is also provided on the second winding surface 324 of the other winding member 322, but this yielding portion 325 is diagonally arranged with the yielding portion 325 on the first winding surface 323, that is, when the yielding portion 325 on the first winding surface 323 is located at a lower position, the yielding portion 325 on the second winding surface 324 is located at an upper position. A clearance portion 325 is provided on the rolling surface of the rolling element 322. The recessed structure of the clearance portion 325 allows the spokes and the conical piece 12 to be accommodated in the clearance portion 325, so that the first rolling surface 323 and the second rolling surface 324 of the two rolling elements 322 can contact each other, so that the rolling element 322 can contact the spokes more closely, and avoid the conical piece 12 from wrinkling during the rolling process due to the excessive gap between the rolling element 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 spoke and the conical piece 12, ensuring that the conical piece 12 can be accurately wound on the end of the spoke.The yielding portions 325 on the two winding members 322 are arranged diagonally. When the yielding portion 325 of one winding member 322 contacts the spoke, the winding surface of the other winding member 322 will fit smoothly on the spoke, thereby avoiding the winding member 322 and the spoke from not being in close contact due to the large space of the yielding portion 325. At the same time, since the winding mechanism 32 will rotate, 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 piece 12 will be wound toward In this case, it is necessary to ensure that there is a yielding portion 325 in contact with the conical piece 12 and the end of the spoke in the opposite direction of the bending of the conical piece 12; by arranging the yielding 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 is to form a space for the spoke to enter from the second direction, it can be ensured that there is a yielding portion 325 in contact with the conical piece 12 and the end of the spoke, so that the conical piece 12 can be accurately wound around the end of the spoke.

[0067] When rolling, the conical sheet 12 attached to the end of the spoke is in an unfolded state before rolling, and only one edge thereof is attached to the end of the spoke. When the spoke is placed in the receiving groove 211, the unfolding and laying direction of the conical sheet 12 may be in different directions. However, when rolling, it is necessary to ensure that the conical sheet 12 can contact the rolling member 322 in a correct manner to prevent the conical sheet 12 from being squeezed by the rolling member 322 and wrinkled or deformed. At the same time, such squeezing may also cause the rolling of the conical sheet 12 to fail. Therefore, a moving mechanism 23 is provided to enable the spoke to be rolled in In the process of entering the position to be rolled, there is an action of moving along the second direction. Through this action and the position of the rolling member 322, the conical piece 12 can contact the rolling member 322, and by setting a certain moving direction, the conical piece 12 can be bent in the direction toward its winding direction. At this time, the conical piece 12 will always maintain contact with the rolling member 322, and then the rolling member 322 approaches each other and contacts the end of the spoke, and then the rolling mechanism 32 is rotated in the correct direction, so that the conical piece 12 can be wound on the end of the spoke in the correct way.

[0068] The spoke end cone piece 12 rolling and rolling device involved in this embodiment mainly includes a fixing component 20 and a rolling and rolling component 30; wherein, the fixing component 20 includes a containing mechanism 21 and a clamping mechanism 22, and the containing groove 211 provided on the containing mechanism 21 can be used to contain the spoke, and when the spoke is placed in the containing groove 211, the length direction of the spoke will be fixed to the first direction, and the end of the spoke can also be exposed in the containing groove 211 in the first direction. Therefore, by providing the containing groove 211, the end of the spoke can be oriented in the correct direction, so as to facilitate the subsequent adjustment of the cone piece. 12 is rolled; the clamping mechanism 22 can clamp and fix the spoke after the spoke is accommodated in the accommodating groove 211, so as to prevent the spoke from rotating or translating due to the influence of the rolling component 30 during the rolling process of the conical piece 12, that is, the position and direction of the spoke can be further fixed by the clamping mechanism 22; by setting the fixing component 20, the operator can easily place the spoke in the accommodating groove 211 during loading, and then fix the spoke through the clamping mechanism 22, and there is no need to adjust and fix the position and direction of the spoke, which can effectively improve the loading 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. At the same time, the winding mechanism 32 includes a radial drive unit 321 and a winding member 322. The radial drive unit 321 can drive multiple winding members 322 to move closer to or away from each other in the radial direction simultaneously or asynchronously. When the winding members 322 move away from each other, a winding space 33 is formed between the winding members 322. The ends of the spokes can be moved to the winding space 33. Then, the winding members 321 are moved closer to or away from each other in the radial direction. 22 approach each other and contact the end of the spoke under the action of the radial driving unit 321, and then the rotating driving mechanism 31 drives the winding mechanism 32 to rotate, and the winding members 322 will also rotate accordingly. During the rotation of the winding members 322, the winding members 322 will apply pressure to the conical piece 12 to deform the conical piece 12, and at the same time, the conical piece 12 will be pressed against the end side wall of the spoke. As the winding mechanism 32 rotates, the winding members 322 will rotate around the end of the spoke for one or more circles until the conical piece 12 is completely fitted to the end of the spoke and a conical section is formed. Through the rolling assembly 30, the conical piece 12 can be accurately and efficiently wound into a conical section surrounding the end of the spoke, and the rotating drive mechanism 31 and the rolling mechanism 32 in the rolling assembly 30 cooperate with each other to realize the rolling action of the conical piece 12; in addition, the rolling assembly 30 also cooperates with the fixing assembly 20, and the fixing assembly 20 can not only facilitate loading, but also fix the spokes when the rolling assembly 30 is working, thereby realizing the automatic rolling of the conical piece 12, reducing labor costs and improving production efficiency.

[0069] Example 2

[0070] Reference Figure 7 and Figure 8 , Embodiment 2 is based on Embodiment 1, and the difference between Embodiment 2 and Embodiment 1 is that the rolling element 322 in the rolling mechanism 32 is set as a roller 328. Each of the rollers 328 rotates around the second axis in the first direction, and the conical sheet 12 is wound to the end of the spoke through the circumferential surface 329 of each of the rollers 328 to form the conical section.

[0071] Specifically, in this embodiment, there are two winding members 322, and the output end of the radial driving unit 321 in the winding mechanism 32 can drive the two winding members 322 to move toward or away from each other in the radial direction relative to the first axis. When the winding member 322 is set as a roller 328, the shaft of the roller 328 is directly fixed on the output end of the radial driving unit 321, and the roller 328 can rotate freely around the second axis where its shaft is located. The outer peripheral side of the roller 328 is a circular surface 329 with a certain width,

[0072] During the winding process, the circumferential surface 329 of the roller 328 will contact the end of the spoke. The winding member 322 is designed as the roller 328. During the winding process, the roller 328 will also rotate around the second axis. While the roller 328 rotates, its circumferential surface 329 will always keep in contact with the end of the spoke around the length direction of the spoke, and the sliding friction can be converted into rolling friction, which significantly reduces the friction between the winding member 322 and the cone 12. The smaller friction makes the winding process smoother, reduces the wear of the cone 12 caused by excessive friction, improves the winding efficiency, and ensures the integrity of the cone 12. Compared with the structure of the winding member 322 in the above technical solution, the winding member 322 of the roller 328 structure is simpler in structure and has a low cost of parts. At the same time, as long as the cone 12 can correctly contact the circumferential surface 329 of the roller 328 in the lifting mechanism, the roller 328 can complete the winding process well, which can effectively improve the winding quality of the cone 12. The width of the circumferential surface 329 of the roller 328 can be further designed to be larger than the size of the conical piece 12 in the left-right direction, thereby ensuring that the circumferential surface 329 of the roller 328 can completely contact the conical piece 12 .

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

[0074] The description of the above specification and embodiments is used to explain the protection scope of the present invention, but does not constitute a limitation on the protection scope of the present invention. Through the enlightenment of the present invention or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent substitutions or other improvements to the embodiments of the present invention or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the present invention.
