Description

Technical Field

[0001] The invention relates to the technical field of wheel rim rotating surface grinding, in particular to a carbon fiber bicycle wheel rim rotating surface grinding device. Background Art

[0002] Carbon fiber bicycle rims have become a key component in the field of high-end bicycle manufacturing due to their light weight, high strength and excellent aerodynamic performance. After the carbon fiber bicycle rims are manufactured, their external rotating surfaces are usually polished to remove the excess material on the surface of the rotating surface. Rotating surface polishing is also an important process to ensure its geometric accuracy and rotating surface quality, which directly affects the dynamic balance performance of the rim and the sealing performance with the tire. In the polishing stage, most manufacturers still use manual polishing, which has high labor costs, low processing efficiency, and it is difficult to ensure product consistency, which seriously restricts mass production capacity.

[0003] Patent No. CN217800733U discloses a surface treatment device for wheel hub production, wherein one end of the clamping block is provided with an inclined surface, the top of the base is located on three sides of the fixed frame and is fixedly connected to a rotating cylinder, the push rod of the rotating cylinder is fixedly connected to a connecting plate, and the bottom of the connecting plate is fixedly connected to an end of the push rod of the rotating cylinder away from the fixed shaft; by making the outer side of the bicycle hub contact with the outer side of the inclined surface, the clamping block is pushed to move, thereby pushing one end of the connecting column to move inside the deep groove, so that the bicycle hub contacts the top of the clamping block, and by opening the solenoid valve to control the rotation of the push rod of the rotating cylinder, the connecting plate drives the second motor to rotate, so that the driven wheel contacts the outer side of the bicycle hub, thereby limiting the position of the bicycle hub, and the bicycle hub can be processed by the grinding wheel to remove burrs on the surface of the bicycle hub without manual grinding.

[0004] However, the above-mentioned grinding device rotates from the outside through a single active wheel and drives the wheel rim to rotate through friction. During this process, the external force applied to the wheel rim is uneven. If the wheel rim is subjected to uneven external force, it will cause the wheel rim itself to deform slightly, which will destroy the geometric roundness of the wheel rim and affect the dynamic balance of the wheel rim. In addition, it will result in the wheel not being able to fit evenly when the tire is installed later.

[0005] In addition, during the grinding process, the rim is grinded from the top with a grinding wheel. After grinding, the rim needs to be turned over and the grinding steps are repeated, which prolongs the grinding time in disguise. Moreover, the outer surface of the bicycle rim is an inclined rotating surface. During the grinding process of the bicycle rim with a grinding wheel, the inner arc portion of the bicycle rim is difficult to contact with the grinding wheel, and incomplete grinding is very likely to occur, affecting the quality of the polished rim.

[0006] Therefore, it is necessary to design a grinding device for the rotating surface of a carbon fiber bicycle rim that can effectively avoid rim deformation and completely grind the outer rotating surface of the rim, aiming at the disadvantages of the existing rim grinding machine in the prior art, where the rim is driven to rotate by a single driving wheel, resulting in uneven force on the rim, which in turn causes rim deformation, and there are dead corners during the grinding of the rotating surface of the rim by the grinding wheel. Summary of the Invention

[0007] In order to overcome the disadvantages of the grinding device in the prior art, where only a single driving wheel drives the rim to rotate, resulting in uneven force on the rim and deformation, and there are dead corners during the grinding of the outer rotating surface of the rim by the grinding wheel, the present invention provides a grinding device for the rotating surface of a carbon fiber bicycle rim, which can balance the force on the rim when driving the rim to rotate and can completely grind all the dead corners on the outer rotating surface of the rim during grinding to ensure the grinding effect.

The present invention integrates the functions of clamping, rotating and grinding, and can perform automatic grinding operations on the wheel rim using an intelligent control system, which not only significantly improves the processing efficiency, but also ensures the consistency of product processing quality.

[0018] 2. The present invention supports the rim through brackets.

The sliding grinding plate and the grinding block swing reciprocally accordingly, ensuring the grinding effect.

[0021] 5. The blower will blow the dust generated during the grinding process towards the support frame. The dust generated by grinding will mix into the water droplets on the inner wall of the support frame. The water flow on the inner wall of the support frame carries the dust and slides downwards, and finally flows into the collection box along the arc-shaped chute. Then, it is screened through the sieve plate at the bottom of the collection box. The water in the dust passes through the sieve plate and falls down into the sliding recovery box. After grinding, the powder recovery box is pushed to the bottom of the collection box, and the collection box will push the dust remaining on the top of the sieve plate into the powder recovery box to classify and recycle the dust and water generated during grinding.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment 1: A grinding device for the rotating surface of a carbon fiber bicycle rim, as Figures 1-9 shown, including a support frame 1, a ring-shaped slideway 101, a rotary frame 102, a control motor 103, a grinding support 104, a bracket 105, a rim clamping mechanism and a rim grinding mechanism. A ring-shaped slideway 101 is fixedly connected to the support frame 1. A rotary frame 102 is slidably connected in the ring-shaped slideway 101. The rotary frame 102 slides along the ring-shaped slideway 101. A bracket 105 is fixedly connected to the ring-shaped slideway 101. The bracket 105 is used to support and hold the rim, and the bracket 105 can also play a positioning role when placing the rim. A grinding support 104 is provided inside the support frame 1. A control motor 103 is installed on the grinding support 104. The rim clamping mechanism is installed on the ring-shaped slideway 101. The rim clamping mechanism is used to clamp the rim on the bracket 105. The rim grinding mechanism is installed on the grinding support 104. The rim grinding mechanism is used to grind the surface of the rim on the bracket 105.

[0034] As Figure 2 and Figure 3 shown, the rim clamping mechanism includes a connection disk 1031, a driving gear 1032, a reduction gear 1033, an internal gear ring 106, a clamping push rod 107 and a sliding clamping plate 108. The connection disk 1031 is rotatably connected to the grinding bracket 104. The driving gear 1032 is fixedly connected to the connection disk 1031. The output shaft of the control motor 103 is fixedly connected to the connection disk 1031. The control motor 103 can drive the connection disk 1031 and the driving gear 1032 to rotate. The reduction gear 1033 is rotatably connected to the grinding bracket 104. The reduction gear 1033 meshes with the driving gear 1032. The internal gear ring 106 is fixedly connected to the rotating frame 102. The internal gear ring 106 meshes with the reduction gear 1033. The driving gear 1032 drives the internal gear ring 106 to rotate through the reduction gear 1033. The clamping push rod 107 is installed on the rotating frame 102. The sliding clamping plate 108 is slidably connected to the rotating frame 102. The sliding clamping plate 108 matches the rim to be ground. The clamping push rod 107 is used to push the sliding clamping plate 108 to slide along the rotating frame 102 to clamp the rim.

[0035] Place the bicycle rim on the bracket 105. Four brackets 105 are fixedly connected to the annular slideway 101. The multiple brackets 105 jointly provide positioning for the rim. After the rim is placed, start the clamping push rod 107. The clamping push rod 107 pushes the sliding clamping plate 108 to approach the rim. When the two sliding clamping plates 108 clamp the rim from both sides, turn off the clamping push rod 107. Then start the control motor 103. The control motor 103 drives the connection disk 1031 to rotate. When the connection disk 1031 rotates, it can drive the reduction gear 1033 to rotate through the driving gear 1032. When the reduction gear 1033 rotates, it drives the internal gear ring 106 to rotate. During the rotation of the internal gear ring 106, it drives the rotating frame 102 to slide along the annular slideway 101, and further drives the rim to rotate on the bracket 105 through the sliding clamping plate 108. During the process of the sliding clamping plate 108 driving the rim to rotate, the rim grinding mechanism grinds the outer surface of the rim. After grinding, the clamping push rod 107 drives the sliding clamping plate 108 to slide back along the grinding bracket 104 to release the clamping of the rim.

[0036] Embodiment 2: On the basis of Embodiment 1, as Figure 2 and Figures 4-6As shown in the figure, the rim grinding mechanism includes a grinding frame 3, an inclined slideway 304, a sliding grinding plate 305, a grinding block 306 and a pushing component. A grinding frame 3 is provided at the top of the grinding support 104. An inclined slideway 304 is fixedly connected to the grinding frame 3. A sliding grinding plate 305 is slidably connected in the inclined slideway 304. A grinding block 306 is fixedly connected to the sliding grinding plate 305. The surface of the grinding block 306 in contact with the rim is a sand surface for grinding the outside of the rim. The grinding block 306 is made of an elastic material to provide buffering during the grinding process, so as to prevent excessive pressure between the sand surface on the grinding block 306 and the rim, which may cause excessive grinding.

[0037] As Figures 4-6 shown in the figure, the pushing component includes a sliding push rod 2, a pushing block 201, a sliding push plate 202, a sliding plate 203, a spreading spring 204 and a guide rod 3001. A guide rod 3001 is fixedly connected inside the grinding frame 3. A sliding push rod 2 is slidably connected to the top of the grinding support 104. A pushing block 201 is fixedly connected to the sliding clamping plate 108. The pushing block 201 is fixedly connected to the sliding push rod 2. The sliding clamping plate 108 drives the sliding push rod 2 to move through the pushing block 201. A sliding push plate 202 is slidably connected inside the grinding frame 3. One side of the sliding push rod 2 in contact with the sliding push plate 202 is an inclined surface. A sliding plate 203 is slidably connected to the guide rod 3001. One side of the sliding push plate 202 facing the sliding plate 203 is an inclined surface. A spreading spring 204 is provided between the sliding plates 203. The spreading spring 204 is sleeved outside the guide rod 3001. The sliding push rod 2 pushes the sliding plate 203 to slide along the guide rod 3001 through the sliding push plate 202. The sliding plate 203 is slidably connected to the sliding grinding plate 305. When the two sliding plates 203 are pushed by the sliding push plate 202 to move closer to each other, the sliding grinding plate 305 is pushed by the sliding plate 203 to slide downward along the inclined slideway 304.

[0038] When the clamping push rod 107 pushes the sliding clamp plate 108 to move closer to the wheel rim, the sliding clamp plate 108 will push the sliding push rod 2 to slide along the grinding bracket 104 through the pushing block 201. When the two sliding push rods 2 move closer to each other along the grinding bracket 104, they will drive the sliding push plate 202 to slide along the grinding frame 3 toward the wheel rim. In this process, the sliding push plate 202 will push the two sliding plates 203 to slide along the guide rod 3001 and move closer to each other. The expansion spring 204 between the two sliding plates 203 is compressed. When the sliding plates 203 move closer to each other along the guide rod 3001, they will push the sliding grinding plate 305 to slide along the inclined slide 304 toward the wheel rim. When the sliding push rod 2 stops moving When the wheel rim is rotated, the grinding block 306 on the sliding grinding plate 305 can just fit with the outer surface of the wheel rim. At this time, the control motor 103 is started and the wheel rim is driven to rotate through the sliding clamping plate 108. During the rotation of the wheel rim, the grinding block 306 grinds the outer surface of the wheel rim. After grinding, the pushing block 201 drives the sliding push rod 2 to slide and reset along the grinding bracket 104. At this time, the sliding push plate 202 is no longer pushed by external force. Under the push of the expansion spring 204, the two sliding plates 203 slide along the guide rod 3001 and move away from each other, and the sliding grinding plate 305 then slides and resets along the inclined slide 304, and the grinding block 306 moves away from the outside of the wheel rim to facilitate the removal of the wheel rim after grinding.

[0039] Embodiment 3: Based on embodiment 2, Figure 2 As shown, it also includes a swing component for controlling the swing of the grinding frame 3, the swing component includes a rotating block 301, a turntable 302 and a telescopic connecting rod 303, the grinding bracket 104 is rotatably connected with the rotating block 301, the top of the driving gear 1032 is fixedly connected to the turntable 302, the turntable 302 rotates with the driving gear 1032, the rotating block 301 is fixedly connected with the telescopic connecting rod 303, the other end of the telescopic connecting rod 303 is rotatably connected to the outside of the round rod at the top edge of the turntable 302, and when the turntable 302 rotates, the rotating block 301 is driven to rotate through the telescopic connecting rod 303.

[0040] After the control motor 103 is started, it drives the driving gear 1032 and the turntable 302 to rotate through the connecting plate 1031. During the rotation of the turntable 302, the rotating block 301 is driven to swing back and forth around the grinding bracket 104 through the telescopic connecting rod 303, so as to drive the grinding frame 3, the sliding grinding plate 305 and the grinding block 306 to swing back and forth, so as to improve the grinding effect on the outer wall of the wheel rim.

[0041] like Figure 1 and Figure 7As shown, it further includes a blowing mechanism for blowing away the powder generated during the grinding process. The blowing mechanism includes a blower 4, an air duct 401, and an air outlet 402. The blower 4 is fixedly connected to the grinding bracket 104, the air duct 401 is fixedly connected to the grinding bracket 104, the outlet of the blower 4 is connected to the air duct 401, the air outlet 402 is fixedly connected to the grinding bracket 104, and the air outlet 402 is fixedly connected to the air duct 401. The dust generated during grinding is blown by the airflow blown out from the air outlet 402 towards the inner wall of the support frame 1.

[0042] As Figure 7 and Figure 8 As shown, it further includes an adsorption assembly for adsorbing the ground powder. The adsorption assembly includes a top bracket 1001, an arc-shaped slideway 1002, a collection box 1003, a water pipe 5, and a spraying pipe 501. The top bracket 1001 is fixedly connected to the support frame 1, the spraying pipe 501 is fixedly connected inside the top bracket 1001, the outlet of the spraying pipe 501 faces the inner wall of the support frame 1, the spraying pipe 501 is fixedly connected to the water pipe 5, water is injected into the water pipe 5 during the grinding process, the water in the water pipe 5 sprays out from the spraying pipe 501, the water mist sprayed by the spraying pipe 501 stays on the inner wall of the support frame 1, the water on the inner wall of the support frame 1 catches the dust in the air, and the water flow carries the dust and slides downwards. An arc-shaped slideway 1002 is provided on the lower side of the support frame 1, and a collection box 1003 is fixedly connected to the bottom of the support frame 1. The arc-shaped slideway 1002 inclines towards the collection box 1003.

[0043] A large amount of dust will be generated during the grinding process. When grinding, start the blower 4, and the blower 4 blows out airflow from the air duct 401 and the air outlet 402. The dust generated during the grinding process moves towards the inner wall of the support frame 1 along with the airflow. During the grinding process, connect the inlet of the water pipe 5 to an external water source, and the water can be sprayed onto the inner wall of the support frame 1 through the spraying pipe 501. The dust blown to the support frame 1 by the airflow will mix with the water, and the mixed water slides down along the support frame 1. And under the action of the arc-shaped slideway 1002, the dust mixed with the water finally converges in the collection box 1003.

[0044] As Figure 8 and Figure 9 As shown, it further includes a recycling assembly for screening and separately recycling water and dust. The recycling assembly includes a sliding recycling box 6, a powder recycling box 601, a return spring 602, a sieve plate 603, and a U-shaped handle 604. A sliding recycling box 6 is provided at the bottom of the support frame 1. During the grinding process, the sliding recycling box 6 is located at the bottom of the collection box 1003. The sieve plate 603 is fixedly connected inside the sliding recycling box 6. The sieve plate 603 separates the collection box 1003 from the sliding recycling box 6. A return spring 602 is provided between the sliding recycling box 6 and the support frame 1. One end of the return spring 602 is fixed on the sliding recycling box 6, and the other end is fixed on the support frame 1. The powder recycling box 601 is fixedly connected to the outside of the sliding recycling box 6, and the U-shaped handle 604 is fixedly connected to the outside of the powder recycling box 601.

[0045] The water on the inner wall of the support frame 1 will eventually fall on the sieve plate 603 in the sliding recovery frame 6, and the excess water will fall into the sliding recovery frame 6 through the sieve plate 603. After the grinding is completed, the worker pushes the powder recovery frame 601 and the sliding recovery frame 6 along the support frame 1 by means of the U-shaped handle 604 to compress the return spring 602. The dust on the sieve plate 603 is blocked by the collection frame 1003. When the sliding recovery frame 6 is pushed to the bottom of the collection frame 1003, the dust on the sieve plate 603 finally falls into the powder recovery frame 601 to classify and recover the dust and water generated during grinding.

[0046] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form. Any technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
