Detailed implementation manners

[0024] The following is a more detailed description of the specific implementation manners of the present invention by referring to the accompanying drawings and describing the embodiments, aiming to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and facilitate its implementation.

[0025] As Figure 1 shown, the cleaning device for the transmission head of the bicycle axle includes a machine platform 1. There is a brush wheel 2 above the machine platform 1. A first driving sprocket 3 is provided on the machine platform 1. The first driving sprocket 3 is meshed and connected with a conveying chain 4. There is a mounting seat 5 on the conveying chain 4. There is a jack 6 at the top end of the mounting seat 5. The mounting seat 5 is connected with a linkage structure. The mounting seat 5 is used to place the parts to be cleaned. The conveying chain 4 is used as a component for conveying the parts and moves through the meshing action of the first driving sprocket 3. There are four first driving sprockets 3 to keep the conveying chain 4 in a tensioned state. The area below the brush wheel 2 is the part cleaning position of the device. The conveying chain 4 runs at a constant speed to convey the parts to the cleaning position, and the transmission head is cleaned by the rotation of the brush wheel 2. The inner diameter of the jack 6 is adapted to the outer diameter of the bottom of the part. After the bottom end of the part is inserted into the jack 6, the transmission head part is located outside the device. At the same time, the bottom of the part will be clamped with the jack 6 due to its own weight and will not rotate relative to the mounting seat 5. And the open end of the jack 6 is vertically upward, which facilitates the loading and unloading process of the production personnel and improves the work efficiency.

[0026] As Figure 2 and Figure 4As shown, the linkage structure includes a linkage sprocket 7. A second drive sprocket 11 is also provided on the machine table 1. The second drive sprocket 11 is meshed and connected with a linkage chain 12. The linkage sprocket 7 and the linkage chain 12 are at the same height. The linkage sprocket 7 is fixedly connected to the bottom of the mounting seat 5. A sleeve 10 is fixedly connected to the bottom of the linkage sprocket 7. The conveying chain 4 includes chain plates 8. A support shaft is fixedly connected to the top of each chain plate 8. The sleeve 10 is rotatably connected to the support shaft. The power equipment built into the machine table 1 provides power for the rotation of the first drive sprocket 3 and the second drive sprocket 11. The second drive sprocket 11 provides power for the operation of the linkage chain 12. Since the linkage sprocket 7 and the linkage chain 12 are arranged at the same height, when the mounting seat 5 is conveyed to the cleaning position by the conveying chain 4, the linkage sprocket 7 contacts the linkage chain 12, and the mounting seat 5 will rotate around the mounting shaft 9, so that each key tooth or tooth gap of the transmission head can contact the brush wheel 2 when the part is conveyed by the conveying chain 4, ensuring that the iron filings are completely cleaned.

[0027] As Figure 1 and Figure 3 shown, a base is provided in the middle of the machine table 1. A mounting plate 15 is provided above the base. A cylinder 13 is provided in the middle of the base. The output end of the cylinder 13 is connected to the bottom of the mounting plate 15. A motor 18 is provided on the mounting plate 15. The brush wheel 2 is connected to the output end of the motor 18. The cylinder 13 provides power to realize the lifting of the mounting plate 15, and the brush wheel 2 is lifted to contact the transmission head of the part. When the equipment stops running, the cylinder 13 resets the mounting plate 15. When parts of different lengths need to be cleaned, only need to control the cylinder 13 to lift the mounting plate 15 to contact the transmission head of the part to meet the production needs.

[0028] As Figure 5 shown, a bearing 17 is provided between the top of the support shaft and the sleeve 10. The support shaft and the sleeve 10 are connected by the bearing 17 to realize their relative rotation. The use of the bearing 17 can reduce the rotation resistance of the sleeve 10, ensure the smooth rotation of the part, is conducive to improving the cleaning effect, and reducing the redundancy of iron filings.

[0029] As Figure 1 shown, the axis of the brush wheel 2 is horizontally arranged. A spray pipe 19 is provided on one side of the brush wheel 2. The brush wheel 2 is arranged with its axis in a horizontal posture, and its power transmission with the motor 18 is realized through a synchronous belt mechanism or a sprocket chain mechanism. When the brush wheel 2 rotates, the acting force exerted by the brush wheel 2 on the transmission head is vertically downward, which is consistent with the gap direction when the part is vertically placed. Therefore, when the brush wheel 2 rotates, the iron filings can be completely and thoroughly cleaned from the transmission head. And when the brush wheel 2 is placed in this posture, it is conducive to preventing the iron filings from being carried out by the brush wheel 2 and splashing, reducing the environmental pollution and safety risks in the workshop. The spray pipe 19 plays an auxiliary cleaning role in the cleaning process. Before or at the same time as the transmission head is cleaned, the spray pipe 19 sprays coolant or lubricant onto the transmission head to reduce the adhesion between the iron filings and the transmission head and further improve the cleaning effect.

[0030] As Figure 2 shown, the conveying chain 4 has a rectangular structure, and the substrate 14 is located inside the conveying chain 4. The conveying chain 4 is maintained in a rectangular tensioned posture by four first driving sprockets 3. The conveying chain 4 rotates continuously to form a circulating system, and production personnel can load and unload materials simultaneously, with high operation convenience.

[0031] As Figure 1 shown, a protective cover 20 is provided outside the linkage chain 12, and side plates 21 are provided at the edge of the machine table 1. The protective cover 20 protects its internal structure, and the protective cover 20 and the side plates 21 can also prevent iron filings from splashing out of the machine table 1 and affecting the workshop environment.

[0032] As Figure 3 shown, a guide rod 16 is provided between the end of the base and the mounting plate 15. The guide rod 16 guides the lifting of the mounting plate 15, which is beneficial to keeping the overall level of the mounting plate 15 and ensuring stable contact between each part of the brush wheel 2 and the part driving head part.

[0033] As Figure 1 shown, the mounting seats 5 are arranged at equal intervals. Mounting shafts 9 are arranged on each link plate 8. The mounting shafts 9 can be directly fixed by welding. The mounting seats 5 are rotationally connected to the mounting posts through sleeves 10 and achieve the effect of equal interval arrangement, so as to meet the batch placement of part cleaning and improve production efficiency.

[0034] The working process is as follows: The staff sequentially inserts the products into the jacks 6 of the mounting seats 5. The equipment starts, the conveying chain 4 runs under the meshing drive of the first driving sprocket 3, the linkage chain 12 runs under the meshing drive of the second driving sprocket 11, the cylinder 13 starts to lift the brush wheel 2 to a height adapted to the product driving head. The product runs with the conveying chain 4 to the cleaning position. When the linkage sprocket 7 meshes with the outside of the linkage chain 12, under the meshing drive of the linkage chain 12, the mounting seat 5 will rotate around the mounting shaft 9. At the same time, it drives the product to rotate. Since the product is in a vertical posture when inserted into the jack 6 and the key tooth or gear tooth gap is in the vertical direction, under the combined action of the cleaning agent and the brush wheel 2, the iron filings in each gap can be smoothly cleaned. After the cleaning is completed, the products are sequentially recovered by the staff from the jacks 6. Due to the circulating operation of the conveying chain 4, production personnel can continuously feed materials, and the subsequent product cleaning process is the same as the above operation.

[0035] The transmission head cleaning device of the bicycle axle realizes the rotation of the mounting seat 5 driving the parts around the mounting shaft 9 under the combined action of the linkage gear and the linkage chain 12 through the conveyance of the parts by the conveyance chain 4. Under the cleaning action of the spray pipe 19 and the brush wheel 2, the complete cleaning of the iron filings in the clearance on the transmission head is realized, ensuring the product quality. Correspondingly, the batch cleaning of the parts is also realized. Compared with the manual or blower cleaning in the prior art, the problems of difficult cleaning and incomplete cleaning of the iron filings are solved, the work efficiency is improved, the labor intensity of the personnel is reduced, and the pollution of the workshop environment and the use of an independent workshop are avoided. The production process is reduced and the cost is lowered.

[0036] The present invention has been described exemplarily in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above-mentioned manner. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present invention; or without improvement, the above-mentioned concept and technical solution of the present invention are directly applied to other occasions, they are all within the protection scope of the present invention.
