Description

Technical Field

[0001] This application relates to the field of bicycle flywheel technology, and in particular to a flywheel lubrication device. Background Technology

[0002] Existing non-motorized vehicles such as tricycles and bicycles use drive systems consisting of a belt and a freewheel. Bicycle freewheels, also known as sprockets, can be divided into multi-stage freewheels and single-stage freewheels. Multi-stage freewheels come in two forms: rotary freewheels and cassette freewheels.

[0003] The ratchet mechanism of a rotary freewheel is located inside the freewheel itself, not on the bicycle hub. The freewheel's inner bore is countersunk, and the ratchet is mounted on the side with the larger inner diameter. To ensure smooth bicycle riding, the internal ratchet mechanism requires lubrication during the production of rotary freewheels. The existing lubrication process is as follows: unassembled rotary freewheels are transported on a conveyor belt. Workers on both sides of the conveyor belt remove the freewheels from the conveyor belt, apply lubricant to the freewheels with brushes, and then thread the freewheel cap ring onto the freewheel.

[0004] For the aforementioned technologies, manual lubrication application is inefficient. Summary of the Invention

[0005] To improve the lubrication efficiency of the internal ratchet of the flywheel, this application provides a flywheel lubrication device and a lubrication assembly process.

[0006] The flywheel lubrication device provided in this application adopts the following technical solution: A flywheel lubrication device includes an assembly platform, a conveying component disposed on one side of the assembly platform in the conveying direction for conveying a flywheel, a detection component for detecting the quality of the flywheel, a pushing component disposed corresponding to the detection component, a positioning component for fixing the flywheel, and a coating component disposed corresponding to the positioning component. The assembly platform has a loading station, a detection station, a pushing station, a positioning station, a lubrication station, and a unloading station along the flywheel conveying direction. The detection component is disposed at the detection station, the pushing component is disposed at the pushing station, the detection station and the pushing station are at the same height, the positioning component is disposed at the positioning station, and the coating component is disposed at the lubrication station, the positioning component and the lubrication station are at the same height.

[0007] By adopting the above technical solution, when using the above assembly equipment, the conveying component transports the flywheel from the loading station along the length of the assembly platform. The flywheel is sequentially transported to the inspection station, positioning station, and unloading station. At the inspection station, the flywheel is first inspected by the inspection component. If a defective flywheel is detected, it is pushed off the assembly platform by the pushing station. When the inspected flywheel is transported to the positioning station, it is fixed by the positioning component, so that the flywheel can correspond to the coating component for coating and lubrication. The above equipment realizes the automated operation of flywheel lubrication and improves lubrication efficiency.

[0008] Optionally, the detection component includes a detection bracket fixedly mounted on the assembly platform and a detection element mounted on the detection bracket; the ejection component includes a push plate rotatably mounted on the assembly platform, a push drive element for driving the push plate to rotate, and a receiving plate. The assembly platform has an installation notch for the push plate to be rotatably mounted. The top surface of the push plate is flush with the top surface of the assembly platform. One end of the push drive element is hinged to the bottom surface of the push plate, and the other end is hinged to the assembly platform. When the detection element detects that the flywheel is defective, it activates the push drive element to push the flywheel to the receiving plate.

[0009] By adopting the above technical solution, the structural composition of the detection component and the ejection component is disclosed. When the conveying component moves a flywheel from the loading station to the detection station, the flywheel is placed on the push plate which is flush with the top surface of the assembly platform. The detection component above the flywheel detects the surface of the flywheel. The detection result is connected to the start of the ejection component. When the flywheel is defective or defective, the drive component is activated to make the push plate tilt downward and rotate, so that the flywheel slides from the push plate to the receiving plate. The flywheel is then recovered at the station next to the receiving plate.

[0010] Optionally, the conveying assembly includes a conveying clamp, a first conveying drive component that drives the conveying clamp to move axially along the flywheel conveying direction, and a second conveying drive component that drives the first conveying drive component to move radially. The conveying clamp has a clamping groove for clamping the flywheel on the side facing the assembly platform.

[0011] By adopting the above technical solution, the structural composition of the conveying assembly is disclosed. The conveying clamp is set on one side of the assembly platform and has a clamping groove that cooperates with the flywheel. The first conveying drive unit drives the conveying clamp to move axially along the conveying direction, so that the flywheel can be pushed from one station to another. After the conveying clamp completes one transport, the second conveying drive unit drives the conveying clamp to move radially away from the assembly platform, so that the clamping state between the conveying clamp and the flywheel is released. Then, under the action of the first conveying drive unit, the conveying clamp is reset to the initial position. When movement is required, the conveying clamp is moved towards the assembly platform again. The above operation is repeated to realize the individual transport of the flywheel by the conveying clamp.

[0012] Optionally, the first conveying drive includes a conveying bracket, a first conveying plate disposed on the conveying bracket, and a first conveying cylinder for driving the first conveying plate to move along the conveying direction; the second conveying drive includes a second conveying cylinder disposed on the top of the first conveying plate and for driving the conveying clamp to move radially, and guide seats disposed on both sides of the second conveying cylinder, wherein the conveying clamp is provided with a guide rod slidably arranged on the guide seat.

[0013] By adopting the above technical solution, the specific structural composition of the first conveying drive component and the second conveying drive component is disclosed. The above structure realizes the axial and radial movement of the conveying clamp plate. The structure is simple, the transmission is stable, and it is convenient for installers to assemble.

[0014] Optionally, the conveying clamp is provided with three clamping slots spaced apart along the conveying direction. The three clamping slots are, in sequence, a first clamping slot, a second clamping slot, and a third clamping slot. The initial position and the end position of the first clamping slot correspond to the loading station and the inspection station, respectively. The initial position and the end position of the second clamping slot correspond to the inspection station and the positioning station, respectively. The initial position and the end position of the third clamping slot correspond to the positioning station and the unloading station, respectively.

[0015] By adopting the above technical solution, the number of clamping slots on the conveying clamp is disclosed. The setting of three clamping slots enables the conveying clamp to convey three flywheels simultaneously. The two states of the first clamping slot correspond to the loading station and the inspection station, respectively; the two states of the second clamping slot correspond to the inspection station and the positioning station, respectively; and the two states of the third clamping slot correspond to the positioning station and the unloading station, respectively. With the above structure, the flywheels on the inspection station and the positioning station can be operated simultaneously, and the loading and unloading of flywheels can be realized simultaneously, thereby improving the overall efficiency of the equipment.

[0016] Optionally, the positioning component includes a first positioning element and a second positioning element. The first positioning element includes a fixed frame disposed on the side of the assembly platform away from the conveying clamp, a positioning seat that is lifted and installed on the fixed frame, and a first positioning lifting element that drives the positioning seat to rise and fall. The positioning seat has a conical positioning groove on the side facing the assembly platform.

[0017] By adopting the above technical solution, when the flywheel is delivered to the positioning station, the first positioning lifting component is activated, causing the positioning seat to descend vertically. During the descent of the positioning seat, the setting of the conical positioning groove enables the position of the flywheel to be adjusted and positioned so that the axis of the flywheel and the central axis of the conical positioning groove are coaxial.

[0018] Optionally, the second positioning component includes a second positioning lifting component disposed at the bottom of the assembly platform, a clamping and fixing component connected to the output shaft of the second positioning lifting component, and a buffer component. The clamping and fixing component includes a clamping bracket, a plurality of clamping cylinders disposed on the clamping bracket, and a clamping rod connected to the clamping cylinders and used to extend into the inner hole of the flywheel. The output shaft of the second positioning lifting component has a clamping and fixing plate for mounting the clamping bracket. The buffer component is disposed between the clamping and fixing plate and the second positioning lifting component.

[0019] By adopting the above technical solution, after the first positioning component completes the initial positioning of the flywheel, the inner hole of the flywheel and the first through hole are arranged coaxially. The second positioning lifting component drives the clamping component to pass vertically upward through the first through hole, and the clamping cylinder drives the clamping rod to further fix the flywheel.

[0020] Optionally, the coating assembly includes a coating lifting member disposed on the first positioning member, a coating member connected to the coating lifting member and used for insertion into the flywheel inner hole, and a drive oil pump connected to the coating member. The positioning seat has a second through hole through which the coating member passes, and the first through hole and the second through hole are arranged coaxially.

[0021] By adopting the above technical solution, after the positioning component completes the fixation of the flywheel, the painting lifting component drives the painting component to pass vertically downward through the second through hole, so that the end of the painting component is inserted into the inner hole of the flywheel and abuts against the ratchet box. After the positioning component and the flywheel are fixed, they are in a coaxial state, so that the painting component and the inner hole of the flywheel are also in a coaxial state. That is, after the flywheel is fixed, the lubrication component and the flywheel are also aligned at the same time.

[0022] Optionally, the coating component includes an insertion main rod and a coating piece circumferentially slidably mounted on the side wall of the insertion main rod. The insertion main rod includes a first rod for fixing the coating lifting component and a second rod slidably arranged within the first rod. The coating piece has an abutment portion on the side facing the insertion main rod. The first rod has a movable chamber for the abutment portion to be slidably mounted. The abutment portion has a first abutment slope. The side wall of the second rod has a second abutment slope that mates with the first abutment slope.

[0023] By adopting the above technical solution, after the main rod is inserted into the inner hole of the flywheel, the inner wall of the coating plate and the ratchet are aligned. At this time, multiple coating plates are in a retracted state. Then, the coating lifting component is activated, causing the output shaft to push the second rod downward. Under the action of the first and second abutting inclined surfaces, the coating plates are spread out in all directions, so that the coating plates abut against the inner wall of the flywheel. Finally, the coating rotation drive component is used to make the coating plates apply lubricant evenly on the inner wall of the flywheel in a circumferential manner to complete the lubrication operation.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. The flywheel lubrication device of this application includes an assembly platform, a conveying chamber, a detection component, an ejection component, a positioning component, and a coating component, which realizes the automated operation of flywheel lubrication and achieves relatively ideal lubrication efficiency; 2. This application uses the first and second positioning components to initially adjust and finally fix the position of the flywheel, respectively, resulting in a relatively stable fixing method; 3. By setting the paint application component and the first positioning component in a corresponding manner, the flywheel is fixed under the action of the positioning component and also completes its correspondence with the paint application component, thereby improving the efficiency of paint application.

Detailed Implementation

[0035] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0036] This application discloses a flywheel lubrication device.

[0037] Reference Figure 1 A flywheel lubrication device includes an assembly platform 1, a conveying assembly 2, a detection assembly 3, a pushing assembly 4, a positioning assembly 5, and a coating assembly 6. The assembly platform 1 is generally a rectangular frame and has an assembly plate 11 for placing and conveying the flywheel. The assembly plate 11 has a loading station, a detection station, a pushing station, a positioning station, a lubrication station, and a unloading station along the conveying direction of the flywheel. The conveying direction of the flywheel is defined as the X-direction, the direction in which the conveying assembly 2 moves towards the assembly platform 1 is defined as the Y-direction, and the height direction is defined as the Z-direction.

[0038] The detection component 3 is located at the detection station, the ejection component 4 is located at the material ejection station, the positioning component 5 is located at the positioning station, and the coating component 6 is located at the coating station. The detection station and the material ejection station are in the same Z-direction, and the positioning station and the lubrication station are in the same Z-direction.

[0039] Conveying assembly 2 transports the flywheel sequentially from the loading station to the inspection station, positioning station, and unloading station. Inspection assembly 3 inspects the surface quality of the flywheel, and the inspection results are transmitted to ejection assembly 4. Ejection assembly 4 unloads defective flywheels in advance based on the inspection results. When the inspected flywheel is transported to the positioning station, positioning assembly 5 positions and fixes the flywheel, ensuring that the flywheel corresponds with coating assembly 6. Finally, with the flywheel fixed, coating assembly 6 lubricates and coats the flywheel, and after coating is completed, the flywheel is unloaded from the unloading station.

[0040] Reference Figure 1 and Figure 2 The assembly platform 1 is equipped with a loading assembly 7 at the starting end of the conveying process to transport the flywheel to the loading station. The loading assembly 7 includes a loading fixing plate 71, a loading sliding plate 72 bolted to the loading plate, a loading lifting plate 73 slidably mounted on the loading sliding plate 72, and a loading clamping component 74 lifted and mounted on the loading lifting plate 73. The assembly plate 11 is fixedly supported by an assembly frame plate 12 for bolting the loading fixing plate 71. The assembly frame plate 12 is U-shaped, and there is a gap between the bottom wall of the U-shaped groove of the assembly frame plate 12 and the top surface of the assembly plate 11 for the flywheel to move.

[0041] The feeding slide plate 72 and the feeding fixed plate 71 are bolted together, and the feeding slide plate 72 extends horizontally along the conveying direction. The feeding slide plate 72 is equipped with a feeding slide rail 721 for the feeding lifting plate 73 to slide horizontally. A feeding sliding cylinder 75 for driving the feeding slide plate 72 is fixedly installed on the top of the feeding slide plate 72 on the side away from the feeding fixed plate 71. The output shaft of the feeding sliding cylinder 75 is arranged horizontally along the conveying direction. The top of the feeding slide plate 72 has an extension plate that is connected and fixed to the output shaft of the feeding sliding drive. A feeding lifting cylinder 76 for driving the feeding clamp 74 to rise and fall is installed on the feeding lifting plate 73. The output shaft of the feeding lifting cylinder 76 is installed vertically downwards, and its output shaft is fixedly connected to the feeding clamp 74. After the flywheels of this application are assembled at the previous station, they are conveyed one by one to directly below the feeding clamp 74 by pushing the cylinder.

[0042] Reference Figure 3 The detection component 3 includes a detection bracket 31 fixed to one side of the assembly plate 11 and a detection element 32 mounted on the detection bracket 31. The detection bracket 31 is generally L-shaped and includes a vertical plate 311 and a horizontal plate 312. The vertical plate 311 is bolted to the side wall of the assembly plate 11, and the horizontal plate 312 is located directly above the detection station of the assembly plate 11. In this embodiment, the detection element 32 is a prior art camera detection device. The detection element 32 transmits the collected flywheel surface image to a computer. The computer determines whether the flywheel is qualified based on the image. Qualified products are continued to be transported to the next station by the conveying component 2, while unqualified products are prematurely unloaded by the ejection component 4.

[0043] The ejector assembly 4 includes a pusher plate 41 rotatably mounted on the assembly plate 11, a pusher drive 42 for driving the pusher plate 41 to rotate, and a receiving plate 43 for receiving the flywheel unloading. The top surface of the assembly plate 11 has a mounting notch 111 for arranging the pusher plate; this mounting notch 111 serves as the inspection station. Rotating shafts for mounting the pusher plate are provided on opposite side walls of the mounting notch 111. The rotating shafts are located on the side of the assembly plate 11 furthest from the inspection bracket 31. The receiving plate 43 is fixedly mounted on the bottom of the inspection bracket 31.

[0044] Assembly plate 11 has an assembly side plate 13 on the side away from the detection bracket 31. The push drive 42 is a telescopic hydraulic cylinder. One end of the push drive 42 is hinged to the assembly side plate 13, and the other end, the output shaft, is hinged to the bottom surface of the push plate 41. When the push plate 41 is installed on the assembly platform 1, the top surface of the push plate 41 is flush with the top surface of the assembly plate 11. When the push drive 42 is activated, the output shaft retracts into the cylinder, causing the push plate 41 to rotate downward toward the assembly side plate 13. The flywheel on the push plate 41 slides down onto the receiving plate 43 under its own weight. A movable material transfer trolley is placed on one side of the receiving plate 43.

[0045] Reference Figure 4 The conveying assembly 2 is located on the side of the assembly plate 11 away from the detection bracket 31.

[0046] The conveying clamp 21 is a rectangular plate extending along the conveying direction. Three clamping slots for clamping the drive flywheel are evenly spaced on the side wall of the conveying clamp 21 facing the assembly plate 11. The clamping slots are sequentially designated as the first clamping slot 211, the second clamping slot 212, and the third clamping slot 213 along the conveying direction. The first conveying drive member 22 drives the conveying clamp 21 to move in the X direction, such that the initial and final positions of the first clamping slot 211 correspond to the loading station and the inspection station, respectively; the initial and final positions of the second clamping slot 212 correspond to the inspection station and the positioning station, respectively; and the initial and final positions of the third clamping slot 213 correspond to the positioning station and the unloading station, respectively.

[0049] The output shaft of the second conveying cylinder 231 faces the assembly plate 11 and is fixedly connected to the middle of the side wall of the conveying clamp 21. One end of the guide rod 233 is fixed to the side of the conveying clamp 21 away from the assembly plate 11, and the other end slides through the guide seat 232 to improve the stability of the conveying clamp 21 when it moves radially.

[0050] Reference Figure 5 The positioning component 5 includes a first positioning element 51 for initially adjusting the position of the flywheel and a second positioning element 52 for finally fixing the flywheel.

[0051] The first positioning component 51 includes a fixed frame 511 disposed on the side of the assembly plate 11 away from the conveying clamp 21, a positioning seat 512 vertically mounted on the fixed frame 511, and a first positioning lifting component 513 for driving the positioning seat 512 to rise and fall. The first positioning lifting component 513 is a drive motor bolted to the top of the fixed frame 511. The output shaft of the first positioning lifting component 513 is arranged vertically downward and coaxially connected to a lifting screw 514. The other end of the lifting screw 514 is rotatably mounted on the base plate of the fixed frame 511. A lifting slider 515 is threadedly mounted on the lifting screw 514, and the two sides of the lifting slider 515 are limited to the fixed frame 511. A lifting platform 516 for mounting the positioning seat 512 is horizontally extended and fixed on the lifting slider 515.

[0052] The positioning seat 512 is fixed to the bottom of the lifting platform 516 by bolts or welding. The end face of the positioning seat 512 facing the assembly plate 11 has a conical positioning groove 5121 for fitting onto the flywheel. The inclination angle of the side wall and height direction of the conical positioning groove 5121 is adapted to the inclination angle of the flywheel teeth, and a guide arc surface 5122 is provided circumferentially at the opening of the conical positioning groove 5121, so that when the first lifting component drives the positioning seat 512 to descend vertically, the side wall of the conical positioning groove 5121 abuts against the flywheel teeth, and the positioning seat 512 drives the flywheel to make minor adjustments on the assembly plate 11, so that the axis of the flywheel is coaxial with the central axis of the positioning seat 512.

[0053] The second positioning component 52 includes a second positioning lifting component 521, a clamping and fixing component 522, and a buffer component 523. The second positioning lifting component 521 is located below the assembly plate 11 and is arranged correspondingly to the positioning seat 512.

The clamping rod 5223 has a Z-shaped cross-section; one end of the clamping rod 5223 is connected to the clamping cylinder 5222, and the other end has a clamping portion 52231 for insertion into the flywheel's inner hole. The clamping portion 52231 has a soft abutment pad 5224 on the side facing the flywheel's inner wall to increase the contact area.

[0055] The clamping cylinder 5222 pushes the clamping rod 5223 to abut against the inner wall of the flywheel, thus finally fixing the flywheel. The clamping bracket 5221 is also provided with a guide block 5225 on top of the clamping cylinder 5222, and the clamping rod 5223 has a guide post 5226 that is slidably arranged on the guide block 5225.

[0057] Reference Figure 7 The assembly plate 11 has a first through hole 112 through which the output shaft of the clamping cylinder 5222 passes vertically. The inner diameter of the first through hole 112 is larger than the inner diameter of the flywheel. After the flywheel is initially positioned by the positioning seat 512, the second positioning lifting member 521 is activated, causing the clamping bracket 5221 to move vertically upward. Then, the clamping cylinder 5222 is activated, causing the clamping part 52231 to press against the inner wall of the flywheel, thus achieving the final fixation of the flywheel.

[0058] The coating assembly 6 is mounted on the first positioning member 51 and can be raised and lowered synchronously with the positioning seat 512. The coating assembly 6 includes a coating rotating member 61 fixed to the top of the lifting platform 516, a coating lifting member 62 connected to the output shaft of the coating rotating member 61, a coating member 63 connected to the output shaft of the coating lifting member 62 and used for insertion into the inner hole of the flywheel, and an oil reservoir 64 for providing lubricant.

The coating frame 66 has an abutment portion 661 that radially inserts into the cavity of the fixing rod 631. The abutment portion 661 has a first abutment bevel 6611 at its end facing the central axis for engaging with a second abutment bevel 6321.

[0063] When the output shaft of the coating lifting component 62 drives the sliding rod 632 to move vertically downward, the second abutting inclined surface 6321 and the first abutting inclined surface 6611 abut against each other, driving the coating frame 66 to move away from the fixed rod 631, thereby causing the multiple coating pieces 633 to spread outward and adhere to the inner wall of the flywheel. Finally, the coating rotating component 61 is activated, causing the coating pieces 633 to rotate circumferentially, thereby lubricating the inner wall of the flywheel.

[0064] The fixing rod 631 has a sliding chamber 6311 for radial sliding of the abutment portion 661, and a return spring 67 for connecting the abutment portion 661 is arranged in the sliding chamber 6311. The return spring 67 is used to reset the coating lifting component 62 after it is reset, thereby resetting the coating plate 633, and at the same time improving the pressing effect of the coating plate 633 on the inner wall of the flywheel.

[0065] After the lubrication operation is completed, the coating assembly 6, the first positioning component 51, and the second positioning component 52 are all reset. The conveyor clamp 21 transports the flywheel to the unloading station to complete the unloading. The assembly plate 11 is equipped with a guide slide at the unloading station to guide the flywheels to move one by one.

[0066] The implementation principle of a flywheel lubrication device according to an embodiment of this application is as follows: The flywheel, located at the starting end of the assembly plate 11, is first conveyed to the loading station via the loading assembly 7. The conveying assembly 2 then sequentially conveys the flywheel along the conveying direction to the inspection station, ejection station, positioning station, lubrication station, and unloading station. When the flywheel reaches the inspection station, the inspection assembly 3 performs a quality inspection. If a defective flywheel is detected, it is ejected earlier via the ejection assembly 4. When conveyed to the positioning station, the flywheel's position is finely adjusted via the first positioning component 51, and then the flywheel is finally fixed via the second positioning component 52. Then, the coating assembly 6 inserts the coating component 63 into the inner hole of the flywheel to complete the lubrication of the flywheel's inner wall. The lubricated flywheel continues to be conveyed to the unloading station under the action of the conveying clamp 21.

[0067] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
