Description

Technical Field

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

[0002] Spokes are crucial components of wheelsets, made of metal or carbon fiber. One end connects to the hub, and the other to the rim, together forming a usable wheel. Spokes are typically long and thin, supporting the rim and holding it in the correct position after connecting to the hub and rim. They also withstand forces from all directions during riding, including impacts from the ground and centripetal forces. A spoke generally consists of the spoke body and connector caps at both ends for connection to the hub and rim, respectively. During manufacturing, the spoke body is typically inserted into the connector cap, and then the cap is tightened to secure it. At this point, a portion of the spoke body protrudes from the connector cap, requiring grinding to align it flush with the cap. Currently, this is usually done manually, with a worker holding the spoke to be ground and pressing the end against the grinding disc of a grinding device. This polishing method is inefficient, and the manual operation can easily lead to uneven polishing of the spoke ends. Utility Model Content

[0017] 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:

[0018] Technical solution one provides a spoke end grinding device, which can grind the part to be ground at the end of a spoke. It includes a frame, a spoke fixture, and a grinding device. The spoke fixture includes a rotating base and a fixture motor. The fixture motor drives the rotating base to rotate around a first axis. A spoke fixing part is provided on the rotating base, and the spoke fixing part is in an upper limit fit with the spoke in a first direction. This allows the spoke end to protrude beyond the spoke fixing part after it is fixedly installed in the spoke fixing part. The limiting fit between the spoke fixing part and the spoke limits the degree of spoke protrusion. The length of the part to be ground varies for different spokes, but all spokes aim to grind the end of the spoke body flush with the connecting cap. Therefore, the relationship between the spoke fixing part and the connecting cap remains consistent. This allows for accurate control of the length of the spoke body end remaining after grinding, regardless of the length of the exposed spoke body end during each grinding operation. Simultaneously, the spoke fixing part rotates with the rotating base around the first axis, forming a circular rotation trajectory. The grinding device is equipped with a grinding wheel that rotates around a second axis. The grinding wheel uses its circumferential side edge as the grinding surface to grind the spokes, and the grinding surface overlaps with the rotation trajectory of the spoke fixing part on the projection plane perpendicular to the first direction. When the spoke fixing part that fixes the spokes rotates to the position of the grinding wheel, the part of the spoke to be ground will contact the grinding surface of the grinding wheel. Since the second axis is perpendicular to the first axis and the grinding wheel is disc-shaped, the part of the spoke to be ground will be gradually ground by the grinding wheel during the rotation of the spoke fixing part until the spoke moves to the plane position formed by the intersection of the first axis and the second axis. At this time, the distance between the connecting cap on the spoke and the grinding surface is the closest. By controlling this distance, the end length of the spoke body left after grinding can be controlled, that is, the length of the part of the spoke body that protrudes from the connecting cap. Since the size and position of the polishing wheel, as well as its relative position to the spoke fixing part, can be predetermined, and the relative position of the polishing wheel and the spoke fixing part does not change during the polishing process, spokes that meet the length requirement of the exposed connecting cap can be repeatedly obtained. Furthermore, due to the positional relationship between the polishing wheel and the spoke fixing part, when the spoke passes the polishing wheel, the part to be polished initially contacts the polishing surface at an angle. At this point, the polishing surface begins polishing the part to be polished from the side, rather than directly from the front. Then, as the spoke moves, the contact between the polishing surface and the part to be polished gradually shifts to the front, allowing the end of the spoke body to be polished flat. This process not only reduces wear on the polishing wheel but also improves the flatness of the spoke body end after polishing.

[0019] The spoke end grinding equipment provided by this technical solution fixes the spokes to the spoke fixing part of the rotating base and makes the spoke fixing part rotate with the rotating base, so that the spokes can pass through the position of the grinding wheel in the grinding device, thereby grinding the exposed part of the spoke end to be ground by the grinding surface of the grinding wheel, thus completing the automated grinding of the spoke end; the spoke end grinding equipment has the advantages of high grinding efficiency and good grinding flatness.

[0020] In technical solution two, the spoke fixing part is located on the circumferential edge of the rotating base, and the spoke fixing part is groove-shaped with a notch. When fixing the spoke, the spoke can be easily inserted into the groove-shaped spoke fixing part from the outer periphery of the rotating base. Furthermore, the notch faces outward relative to the first axis and is perpendicular to the first axis. During the process of inserting the spoke into the notch, the insertion direction of the spoke is easier to apply force, ensuring that the spoke is inserted into the spoke fixing part in the correct posture.

[0021] In technical solution three, a limiting surface is provided in the spoke fixing part, and the connecting cap of the spoke overlaps on the limiting surface. This can accurately limit the positional relationship between the spoke fixing part and the connecting cap, thereby ensuring that the degree of exposure of the connecting cap in the part of the spoke exposed from the spoke fixing part is always consistent.

[0022] In technical solution four, the first direction is the up and down direction. Therefore, the spokes can be suspended from the spoke fixing part by gravity. When feeding, the spokes can be easily hung in the spoke fixing part from the circumferential edge of the rotating base. Under the action of gravity, the connecting cap on the spoke will sit on the limiting surface. There is no need to adjust the position of the spokes. This can ensure that the degree of exposure of the connecting cap is consistent.

[0023] In technical solution five, the frame includes a limiting base plate, and a limiting wall is provided on the limiting base plate. When the spoke fixing part rotates with the rotating base, when the spoke fixing part enters the range of the limiting wall, the limiting wall will limit the spoke inward relative to the first axis, thereby restricting the spoke in the space formed by the spoke fixing part and the limiting wall, and preventing the spoke from falling off the spoke fixing part due to centrifugal force during the rotation of the spoke fixing part.

[0024] In technical solution six, a feeding notch is provided on the limiting plate to facilitate the feeding of spokes to the spoke fixing part.

[0025] In technical solution seven, a feeding component is provided in the spoke fixture. The feeding part of the feeding component protrudes from the rotation trajectory of the spoke fixing part and has an inclined feeding surface. After the spokes are ground, the spokes will rotate with the spoke fixing part to the position of the feeding component, and the spokes will abut against the feeding surface. The feeding surface will apply an outward pushing force relative to the first axis to the spokes, thereby causing the ground spokes to automatically fall off from the spoke fixing part, and then the fallen spokes can be collected.

[0026] In technical solution eight, a clamping device is provided, and a clamping notch is provided on the limiting plate. The elastic movable component of the clamping device will cause the abutment part of the abutment component to maintain the tendency to move towards the position of the rotating base along the second direction. When the spoke rotates to the position of the clamping notch, the depth of the spoke fixing part makes the spoke flush with or protrude from the edge of the groove of the spoke fixing part. Therefore, the abutment part will push the spoke inward relative to the first axis, thereby firmly fixing the spoke in the spoke fixing part. When the part to be polished is polished, the spoke can be prevented from shaking due to insecure fixing, thus improving the polishing flatness.

[0027] In technical solution nine, the abutting component forms an abutting part through the peripheral edge of the rotating abutting wheel. When the peripheral edge of the abutting wheel abuts against the spoke, it can rotate with the rotation of the spoke, thereby transforming the friction between the abutting part and the spoke into rolling friction, reducing the frictional force between the two, ensuring the smooth rotation of the rotating base, and also reducing the wear on the surface of the spoke.

[0028] In technical solution ten, the abutting component includes a sliding seat, which allows the abutting component to slide in the second direction under the action of the elastic movable component; the elastic movable component includes a first fixed seat, a second fixed seat, and an elastic element. The first fixed seat and the second fixed seat are used to fix the frame and the sliding seat, and the elastic element can be embedded into the first mounting groove and the second mounting groove respectively provided on the first fixed seat and the second fixed seat, thereby applying a thrust to the abutting component to move in the second direction toward the position of the rotating base.

[0029] In technical solution eleven, an adjustment device is provided. The mounting base in the adjustment device is used to fix the grinding device and is equipped with an adjustment screw and an adjustment nut. The position of the adjustment nut relative to the adjustment screw can be adjusted by rotating it. At the same time, the mounting base and the adjustment nut are in a limiting fit. Therefore, the position of the mounting base can be adjusted by adjusting the position of the adjustment nut, thereby adjusting the position of the grinding surface of the grinding device relative to the rotating base, and further adjusting the length of the part of the spoke body exposed at the end of the connecting cap after grinding.

[0030] There are twelve technical solutions. The adjustment device also includes several sliding shafts. The sliding shafts can improve the stability of the mounting base when it moves along the first direction, avoid tilting when adjusting the position of the mounting base, and improve the accuracy and stability of the grinding device position adjustment.

[0051] Example

[0052] This utility model embodiment relates to a spoke end grinding device, which is used to grind the ends of semi-finished spokes 10 so that the ground ends of the spokes 10 meet the requirements. (Refer to...) Figure 4The spoke 10 to be polished includes a spoke body 11 and a connecting cap 12. The connecting cap 12 is sleeved and fixed at the end of the spoke body 11, and before polishing, the end of the spoke body 11 of the spoke 10 protrudes from the connecting cap 12, forming a polishing portion 13. It is readily understood that the "end of the spoke 10" or "end of the spoke body 11" referred to in this specification and claims refers to the portion of the spoke 10 near its end point in the length direction; it is a general location designation, and those skilled in the art can clearly understand the meaning of "end" based on the content described in this specification and claims. Before polishing, a portion of the spoke body 11 protrudes from the connecting cap 12. The portion of this protruding portion that does not meet the requirements is the aforementioned polishing portion 13. Using the spoke 10 end polishing device involved in this embodiment, the polishing portion 13 can be removed, thereby ensuring that the length of the portion of the spoke body 11 protruding from the connecting cap 12 meets the requirements. There are two scenarios for meeting the requirements here: one is that the spoke body 11 does not protrude from the connecting cap 12 at all, meaning the end face of the spoke body 11 is flush with the end face of the connecting cap 12; the other is that part of the spoke body 11 protrudes from the connecting cap 12, meaning the end face of the spoke body 11 is higher than the end face of the connecting cap 12. The spoke body 11 can be made of metal or carbon fiber; in this embodiment, carbon fiber is used, and the connecting cap 12 is made of metal.

[0053] Reference Figure 1 and Figure 2 The spoke end polishing equipment involved in this embodiment includes a frame 20, a spoke fixture 30, a polishing device 40, a clamping device 50, and an adjusting device 60.

[0054] Reference Figure 1 and Figure 2 The frame 20 includes a limiting base plate 21, a clamping base plate 22, a main support 23, a receiving component 24, a fixture mounting plate 25, a fixture support shaft 26, and a motor mounting plate 27. The main support 23 includes multiple legs, with adjustment seats at the bottom of each leg for adjusting the height of the main support 23. The main support 23 is configured as a stepped structure with three levels. The receiving component 24 is located on the first level, the spoke fixture 30 is located on the second level, and the grinding device 40, clamping device 50, and adjustment device 60 are located on the third level. The receiving component 24 is a plate-shaped member, bolted to the main support 23, and has an upward-facing surface for receiving spokes 10 falling from the spoke fixture 30.

[0055] Reference Figure 3A fixture mounting plate 25, a plate-shaped component extending horizontally, is bolted to the second step of the main support 23. Multiple fixture support shafts 26, extending vertically, are bolted to the fixture mounting plate 25. These support shafts are arranged in a ring around a predetermined axis corresponding to each spoke fixture 30. In this embodiment, the vertical direction is the first direction as described in the specification and claims, and the front-back direction is the second direction as described in the specification and claims. A motor mounting plate 27, extending horizontally, is bolted to the top of each fixture support shaft 26 and is used for fixing the spoke fixture 30.

[0056] Reference Figure 1 and Figure 2 The limiting plate 21 and the pressing plate 22 are both fixedly installed on the third step of the main bracket 23. Their structure and function are described in detail below.

[0057] Reference Figure 3 The spoke fixture 30 includes a rotating base 31 and a fixture motor 32. The rotating base 31 is rotatably mounted on the frame 20 about a first axis in a first direction, and has at least one spoke fixing part 33 on it. The fixture motor 32 is drively connected to the rotating base 31 to drive the rotating base 31 to rotate. The spoke fixing part 33 is engaged with the spoke 10 in the first direction, and the end of the spoke 10 is exposed outside the spoke fixing part 33. The relative positional relationship between the connecting cap 12 of each spoke 10 and the spoke fixing part 33 is consistent. The position of the spoke fixing part 33 on the rotating base 31 is configured to rotate with the rotating base 31 about the first axis. The spoke fixing part 33 is located on the circumferential edge of the rotating base 31 relative to the first axis, and is groove-shaped with a slot 331 for the spoke 10 to be embedded and fixed. The slot 331 faces outward relative to the first axis and is perpendicular to the first axis. The spoke fixing part 33 is provided with a limiting surface 332 perpendicular to the first direction. The connecting cap 12 of the spoke 10 overlaps the limiting surface 332 to form a limiting fit with the spoke fixing part 33 in the first direction. The first direction is the up-down direction, and the spoke 10 is suspended from the spoke fixing part 33 by gravity.

[0058] Specifically, refer to Figure 3The spoke fixture 30 includes a rotating base 31 and a fixture motor 32. The fixture motor 32 is fixedly mounted on the motor mounting plate 27 of the frame 20, and the main body of the fixture motor 32 is located below the motor mounting plate 27, that is, in the space enclosed by the fixture support shaft 26. The output end of the fixture motor 32 passes through the motor mounting plate 27 and is fixedly connected to the rotating base 31, so that the rotating base 31 can be driven to rotate around a first axis in a first direction by the fixture motor 32. In this embodiment, taking the spoke fixture 30 located on the left side as an example, its rotation direction is clockwise when viewed from top to bottom.

[0059] The rotating base 31 includes a rotating disk 311 and several spoke fixing seats 312. Several fixing seat mounting slots 313 are evenly arranged at fixed circumferential intervals on the rotating disk 311. These fixing seat mounting slots 313 are connected to the circumferential edge of the rotating disk 311, meaning they have open openings on the circumferential edge of the rotating disk 311. A spoke fixing seat 312 is bolted to each fixing seat mounting slot 313. Therefore, these spoke fixing seats 312 are also evenly arranged at fixed circumferential intervals on the rotating disk 311, and their outer edges are flush with the circumferential edge of the rotating disk 311. In this embodiment, the peripheral edge of the rotating disk 311 is circular, that is, the projection shape of the rotating disk 311 when viewed from above is circular. The outer edge of the spoke fixing seat 312 is arc-shaped, and the arc length and central angle of the arc corresponding to the position of the rotating disk 311 are equal. Therefore, after the spoke fixing seat 312 is fixedly installed on the rotating disk 311, the overall projection shape of the entire rotating base 31 when viewed from above is also circular.

[0060] Reference Figure 4 Each spoke fixing seat 312 has the aforementioned spoke fixing portion 33 formed on it. The spoke fixing portion 33 is provided on the outer surface of the spoke fixing seat 312, that is, on the peripheral edge of the rotating base 31. It is a groove-shaped structure with a slot 331, the orientation of which is perpendicular to the first axis. When fixing the spoke 10, the spoke 10 can be easily inserted into the groove-shaped spoke fixing portion 33 from the outer periphery of the rotating base 31. Furthermore, since the slot 331 is perpendicular to the first axis and faces outward relative to the first axis, the insertion direction of the spoke 10 is easier to apply force during the insertion process, ensuring that the spoke 10 is inserted into the spoke fixing portion 33 in the correct posture.

[0061] In the spoke fixing part 33, a limiting surface 332 is provided. The limiting surface 332 is located on the lower side of the spoke fixing part 33 in the vertical direction and extends in the horizontal direction, thereby forming a stepped structure with the groove wall of the spoke fixing part 33. In the structure of the spoke 10, the radial dimension of the connecting cap 12 is larger than the radial dimension of the end position of the spoke body 11 where it is located. Therefore, the stepped structure formed by the limiting surface 332 on the spoke fixing part 33 is just adapted to the shape of the spoke 10 at this position. The connecting cap 12 can overlap the limiting surface 332, thereby forming a limiting in the first direction between the spoke 10 and the spoke fixing part 33. By providing a limiting surface 332 in the spoke fixing part 33 and having the connecting cap 12 of the spoke 10 overlap the limiting surface 332, the positional relationship between the spoke fixing part 33 and the connecting cap 12 can be accurately defined, thereby ensuring that the degree of exposure of the connecting cap 12 in the part of the spoke 10 exposed from the spoke fixing part 33 remains consistent.

[0062] Specifically, in this embodiment, the first direction is the vertical direction. Therefore, when the spoke 10 is embedded in the spoke fixing part 33, it can be subjected to gravity, causing the connecting cap 12 to automatically overlap on the limiting surface 332, thereby suspending the spoke 10 in the spoke fixing part 33. During feeding, the spoke 10 can be conveniently hung in the spoke fixing part 33 from the circumferential edge of the rotating base 31. Under the action of gravity, the connecting cap 12 on the spoke 10 will sit on the limiting surface 332, eliminating the need to adjust the position of the spoke 10 and ensuring that the degree of exposure of the connecting cap 12 remains consistent.

[0063] In this embodiment, after the spoke 10 is embedded into the spoke fixing part 33 and suspended, the connecting cap 12 of the spoke 10 will partially protrude from the upper surface of the spoke fixing part 33. Since the position of the connecting cap 12 on the spoke body 11 is fixed, the degree to which the connecting cap 12 protrudes from the spoke fixing part 33 after overlapping the limiting surface 332 of the spoke fixing part 33 is also fixed. Meanwhile, the length of the part to be polished 13 above the connecting cap 12 may vary on different spokes 10, but the final required length of the part of the spoke body 11 protruding from the connecting cap 12 is consistent. Therefore, by using the connecting cap 12 to position the part to be polished 13, it can be ensured that the end shape and dimensions of the spoke 10 meet the requirements after each polishing.

[0064] Reference Figure 5The grinding device 40 is fixed to the frame 20 and is provided with a grinding wheel 41 that rotates about a second axis perpendicular to the first direction. The grinding wheel 41 is located on the first side of the rotating base 31 in the first direction, and its peripheral edge relative to the second axis forms a grinding surface 42 for grinding the part 13 to be ground. The grinding surface 42 overlaps with the rotation trajectory of the spoke fixing part 33 on the projection plane perpendicular to the first direction.

[0065] The limiting base plate 21 is provided with a limiting wall 211 adapted to the rotation trajectory shape of the spoke fixing part 33. The limiting wall 211 is parallel to the first axis and corresponds to the position of the spoke fixing part 33, so as to limit the spoke 10 that enters its range and is located in the spoke fixing part 33 relative to the first axis. The limiting base plate 21 is provided with a feeding notch 212 that breaks the limiting wall 211 in the circumferential direction relative to the first axis. The rotating base 31 is exposed outside the range of the limiting wall 211 at the position of the feeding notch 212.

[0066] Furthermore, the adjustment device 60 is fixedly connected to the frame 20 and has a mounting base 61 adapted to slide relative to the frame 20 in a first direction; the grinding device 40 is fixedly mounted on the mounting base 61; the adjustment device 60 also includes an adjustment screw 62 extending in the first direction and an adjustment nut 63 threadedly connected to the adjustment screw 62; the mounting base 61 is limited in the first direction with the adjustment nut 63, so as to adjust the position of the mounting base 61 relative to the spoke fixing part 33 by the position of the adjustment nut 63 on the adjustment screw 62. The adjustment device 60 also includes a plurality of sliding shafts 64 extending in the first direction and fixedly connected to the frame 20; the mounting base 61 and each of the sliding shafts 64 are clearance-fitted in the first direction, and the position of each of the sliding shafts 64 is configured to allow the mounting base 61 to slide only in the first direction.

[0067] Specifically, refer to Figure 1 and Figure 5 A limiting plate 21 is bolted to the upper side of the third step of the main support 23. A circular hole-like structure is formed on the front side of the limiting plate 21. The inner wall of this hole-like structure forms a limiting wall 211, and the hole-like structure has an opening in the circumferential direction, forming a feeding notch 212. Specifically, taking the hole-like structure on the left as an example, its feeding notch 212 is located on the left front side. The inner diameter of this hole-like structure matches the outer diameter of the rotating base 31, and the vertical position of the rotating base 31 matches the position of the limiting wall 211. Both axes are the first axis, therefore, referring to... Figure 2The rotating base 31 can rotate within the range of the limiting wall 211. The portion of the rotating base 31 located at the feeding notch 212 does not fall within the range of the limiting wall 211, while the remaining portion forms a limiting engagement with the limiting wall 211. During the rotation of the spoke fixing part 33 with the rotating base 31, when the spoke fixing part 33 enters the range of the limiting wall 211, the limiting wall 211 will limit the spoke 10 inward relative to the first axis, thereby confining the spoke 10 within the space formed by the spoke fixing part 33 and the limiting wall 211. This prevents the spoke 10 from falling out of the spoke fixing part 33 due to centrifugal force during the rotation of the spoke fixing part 33. Simultaneously, the spoke 10 can be easily embedded and fixed into the spoke fixing part 33 through the feeding notch 212.

[0068] At the rear side of the perforated structure, an adjustment device 60 is fixedly mounted on the limiting base plate 21, and a grinding device 40 is fixedly mounted on the adjustment device 60. The adjustment device 60 includes four sliding shafts 64 extending in the vertical direction and a mounting base 61 that is clearance-fitted with the sliding shafts 64 in the vertical direction. The grinding device 40 is fixedly mounted on the lower surface of the mounting base 61. The motor of the grinding device 40 is fixedly connected to the mounting base 61 by bolts. At the same time, a rotatable grinding wheel 41 is provided at the front end of the grinding device 40. The circumferential edge of the grinding wheel 41 forms a grinding surface 42, and the position of the grinding wheel 41 corresponds exactly to the rotation trajectory of the spoke fixing part 33 on the rotating base 31. When the spoke fixing part 33 rotates, it will pass under the grinding wheel 41, and the grinding wheel 41 can grind the end of the spoke 10 in the spoke fixing part 33 at this time.

[0069] In the adjustment device 60, four sliding shafts 64 are arranged at the four corners of the mounting base 61 to limit the mounting base 61 to slide only in the vertical direction without tilting, thus improving the accuracy and stability of the position adjustment of the grinding device 40. The adjustment device 60 also includes two adjusting screws 62 and four adjusting nuts 63. One adjusting screw 62 is threadedly engaged with two adjusting nuts 63. These two adjusting screws 62 are arranged on both sides of the mounting base 61 in the horizontal direction, and the left and right sides of the mounting base 61 are respectively clamped and fixed by two adjusting nuts 63 corresponding to one adjusting screw 62. By rotating the adjusting nuts 63, the height position of the mounting base 61 relative to the upper surface of the limiting base plate 21 in the vertical direction can be adjusted, thereby adjusting the height position of the grinding wheel 41 of the grinding device 40 relative to the upper surface of the limiting base plate 21. Therefore, the position of the grinding surface 42 of the grinding device 40 relative to the rotating base 31 can be adjusted by the adjustment device 60, thereby adjusting the length of the portion of the spoke body 11 exposed above the connecting cap 12 after grinding.

[0070] In addition, refer to Figure 2 , Figure 3 and Figure 4The spoke fixture 30 further includes a feeding component 34, which is fixed to the frame 20 and has a feeding portion 341. The feeding portion 341 is positioned corresponding to the feeding notch 212, and it protrudes radially from the first axis beyond the rotation trajectory of the spoke fixing portion 33. It also has a feeding surface 342 that extends obliquely in the same direction as the rotation direction of the rotating base 31, so as to push the spoke 10 outward relative to the first axis and disengage it from the spoke fixing portion 33 where it is located when the spoke 10 passes by.

[0071] Specifically, the unloading component 34 is a long strip-shaped member fixedly mounted on the motor mounting plate 27. It extends radially outward beyond the peripheral edge of the rotating base 31, and the portion protruding from the outside of the rotating base 31 forms the unloading section 341. An unloading ramp is provided on the unloading section 341. The inclination direction of the unloading ramp is consistent with the rotation direction of the rotating base 31. Here, "consistent" means that the unloading ramp inclines from the inside out along the rotation direction of the rotating base 31. For example, if the rotation direction of the rotating base 31 is clockwise when viewed from above, then the unloading ramp inclines from the inside out in a clockwise direction when viewed from above. It is easy to understand that the unloading ramp can be either a flat surface or an arc surface; this does not affect the unloading ramp's function. After the spokes 10 are polished, they rotate with the spoke fixing part 33 to the position of the unloading part 34, and the spokes 10 come into contact with the unloading surface 342. The unloading surface 342 applies an outward pushing force relative to the first axis to the spokes 10, thereby causing the polished spokes 10 to automatically fall out of the spoke fixing part 33. The fallen spokes 10 can then be collected. In addition, it should be noted that the unloading part 341 is set at the position corresponding to the loading notch 212 because only at the loading notch 212 can the spokes 10 fall out of the spoke fixing part 33 without being restricted by the limiting wall 211. However, the position of the unloading part 341 should be as close as possible to the upstream position of the loading notch 212 along the rotation direction of the rotating base 31, so that loading can be carried out normally downstream of the unloading part 341.

[0072] Furthermore, referring to Figure 6The limiting base plate 21 is provided with a pressing notch 213 that corresponds to the position of the grinding wheel 41 and breaks the limiting wall 211 in the circumferential direction relative to the first axis; the depth of the spoke fixing part 33 in the radial direction of the rotating base 31 relative to the first axis is configured such that the spoke 10 is flush with or protrudes from the edge of the groove 331 of the spoke fixing part 33; the pressing device 50 is fixed to the frame 20 and includes an abutting component 51 and an elastic movable component 52; the abutting component 51 is slidably mounted on the frame 20 in a second direction parallel to the second axis and is provided with an abutting part 511; the elastic movable component 52 elastically acts on the abutting component 51 and the frame 20 in the second direction to push the abutting part 511 of the abutting component 51 inward relative to the first axis to push the spoke 10, which is rotated to the pressing notch 213 and located in the spoke fixing part 33.

[0073] The abutment component 51 includes an abutment wheel 512 that rotates about a third axis in a first direction, and the abutment portion 511 is formed by the peripheral edge of the abutment wheel 512 relative to the third axis. The abutment component 51 includes a sliding seat 513, and the elastic movable component 52 includes a first fixed seat 521, a second fixed seat 522, and an elastic element 523. The sliding seat 513 is slidably mounted on the frame 20 in a second direction, and the abutment wheel 512 is rotatably mounted on the sliding seat 513. The first fixed seat 521 is fixedly mounted on the frame 20 and has a first mounting groove. The second fixed seat 522 is fixedly mounted on the sliding seat 513 and has a second mounting groove corresponding to the position of the first mounting groove. The elastic element 523 extends into the first mounting groove and the second mounting groove at both ends in the second direction and abuts against the bottom of the first mounting groove and the second mounting groove, respectively.

[0074] Specifically, refer to Figure 1 and Figure 6The limiting base plate 21 is also provided with a clamping notch 213, the position of which corresponds to the position of the second axis of the grinding wheel 41 in the vertical direction. A clearance hole 214 is provided on the rear side of the clamping notch 213, which communicates with the hole-like structure on the front side of the limiting base plate 21 for forming the limiting wall 211 through the clamping notch 213. A clamping base plate 22 is fixedly connected to the lower side of the third step of the main support 23 by bolts. A clamping device 50 is fixedly installed on the clamping base plate 22, and a slide rail 28 extending along the second direction is provided on the clamping base plate 22. In the clamping device 50, a first fixed seat 521 is bolted to the clamping base plate 22. A first mounting groove is recessed on the front surface of the first fixed seat 521. A second fixed seat 522 is provided corresponding to the position of the first fixed seat 521. The second fixed seat 522 is bolted to a sliding seat 513, and a second mounting groove is recessed on the rear surface of the second fixed seat 522. The elastic element 523 is a spring, with both ends inserted into the first and second mounting grooves for fixation and abutting against the bottom of the first and second mounting grooves. Its elasticity allows the second fixed seat 522 to tend to move forward. The sliding seat 513 is slidably mounted on the slide rail 28, allowing it to slide freely in the second direction to change position. An abutting wheel 512 is mounted on the upper surface of the sliding seat 513 via a bearing structure. This abutting wheel 512 rotates about a third axis along the first direction, and its peripheral edge forms an abutting portion 511. The abutment wheel 512 is provided in the clearance hole 214 so that the peripheral edge of the abutment wheel 512 can correspond to the clamping notch 213. When the spoke 10 rotates to the position of the clamping notch 213, the depth of the spoke fixing part 33 makes the spoke 10 flush with or protrude from the edge of the groove 331 of the spoke fixing part 33. Therefore, the abutment part 511 will push the spoke 10 inward relative to the first axis, thereby firmly fixing the spoke 10 in the spoke fixing part 33. When the part to be polished 13 is polished, the spoke 10 can be prevented from shaking due to insecure fixing, thus improving the polishing flatness. In the abutment assembly 51, the peripheral edge of the rotating abutment wheel 512 forms an abutment portion 511. When the peripheral edge of the abutment wheel 512 abuts against the spoke 10, it can rotate with the rotation of the spoke 10, thereby converting the friction between the abutment portion 511 and the spoke 10 into rolling friction, reducing the frictional force between the two, ensuring the smooth rotation of the rotating base 31, and also reducing the wear on the surface of the spoke 10.

[0075] This utility model relates to a spoke end grinding device, which can grind the part 13 to be ground at the end of the spoke 10. It includes a frame 20, a spoke fixture 30, and a grinding device 40. The spoke fixture 30 includes a rotating base 31 and a fixture motor 32. The fixture motor 32 can drive the rotating base 31 to rotate around a first axis. A spoke fixing part 33 is provided on the rotating base 31, and the spoke fixing part 33 is in a limiting fit with the spoke 10 in a first direction. This allows the end of the spoke 10 to protrude beyond the spoke fixing part 33 after it is fixedly installed in the spoke fixing part 33. Furthermore, the limiting fit between the spoke fixing part 33 and the spoke 10 limits the extent to which the spoke 10 is exposed. The length of the part 13 to be polished is different for different spokes 10, but all spokes 11 are polished to the end until they are flush with the connecting cap 12. Therefore, the relationship between the spoke fixing part 33 and the connecting cap 12 is kept consistent. In this way, no matter how long the exposed end of the spoke body 11 is, the length of the end of the spoke body 11 left after polishing can be accurately controlled each time. At the same time, the spoke fixing part 33 also rotates with the rotating base 31 around the first axis, thereby forming a circular rotation trajectory. The grinding device 40 is equipped with a grinding wheel 41 that rotates around a second axis. The grinding wheel 41 uses its circumferential side edge as a grinding surface 42 to grind the spokes 10, and the grinding surface 42 overlaps with the rotation trajectory of the spoke fixing part 33 on a projection plane perpendicular to the first direction. When the spoke fixing part 33, to which the spokes 10 are fixed, rotates to the position of the grinding wheel 41, the part 13 of the spokes 10 to be ground will contact the grinding surface 42 of the grinding wheel 41. Since the second axis is perpendicular to the first axis and The grinding wheel 41 is disc-shaped, so during the rotation of the spoke fixing part 33, the part 13 of the spoke 10 to be ground will be gradually ground by the grinding wheel 41 until the spoke 10 moves to the plane position formed by the intersection of the first axis and the second axis. At this time, the distance between the connecting cap 12 on the spoke 10 and the grinding surface 42 is the closest. By controlling this distance, the length of the end of the spoke body 11 left after grinding can be controlled, that is, the length of the part of the spoke body 11 that protrudes from the connecting cap 12. Since the size and position of the grinding wheel 41 and its relative position with the spoke fixing part 33 can be predetermined, and the relative position of the grinding wheel 41 and the spoke fixing part 33 does not change during the grinding process, the spoke 10 that meets the length requirement of the part of the connecting cap 12 exposed can be obtained repeatedly.Furthermore, due to the positional relationship between the polishing wheel 41 and the spoke fixing part 33, when the spoke 10 passes the polishing wheel 41, the part to be polished 13 will first contact the polishing surface 42 at an angle. At this time, the polishing surface 42 will start polishing the part to be polished 13 from the side position, rather than starting polishing directly from the front of the part to be polished 13. Afterwards, as the spoke 10 moves, the contact between the polishing surface 42 and the part to be polished 13 will gradually turn to the front, so that the end of the spoke body 11 can be polished flat. Through this process, not only can the wear of the polishing wheel 41 be reduced, but the flatness of the end of the spoke body 11 after polishing can also be improved.

[0076] The aforementioned spoke 10 end grinding device fixes the spoke 10 to the spoke fixing part 33 of the rotating base 31 and makes the spoke fixing part 33 rotate with the rotating base 31, so that the spoke 10 can pass through the position of the grinding wheel 41 in the grinding device 40, thereby grinding the exposed part 13 to be ground at the end of the spoke 10 through the grinding surface 42 of the grinding wheel 41, thus completing the automated grinding of the spoke 10 end; the spoke 10 end grinding device has the advantages of high grinding efficiency and good grinding flatness.

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.
