Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy disc brake hub end cap spraying technology, and more specifically, it relates to a spraying device for processing aluminum alloy disc brake hub end caps for two-wheeled electric vehicles. Background Technology

[0002] In existing technologies, the aluminum alloy disc brake hub end cap spraying device for two-wheeled electric vehicles is a key piece of equipment for the surface treatment of precision parts. Its performance directly affects the corrosion resistance, aesthetics, and service life of the product. However, the spraying devices currently on the market still have significant shortcomings in terms of functional design and operational stability, which limits the realization of high-quality spraying effects.

[0003] In existing technologies, most spraying devices for processing aluminum alloy disc brake hub end caps for two-wheeled electric vehicles adopt a fixed flow design. Their paint delivery system typically consists of a simple pressure pump, a fixed-diameter delivery pipeline, and nozzles. While this design is simple in structure, it has significant limitations: First, due to the lack of an effective flow regulation mechanism, the device cannot flexibly adjust the paint delivery speed, resulting in suboptimal spraying effects when dealing with paints of different viscosities or workpieces of different materials. Second, the fixed flow design makes it difficult to adjust the paint output according to the needs of different parts of the workpiece during spraying, easily leading to uneven coating, with some areas having excessively thick paint and others insufficient. Furthermore, the fixed flow system cannot adapt to changes in ambient temperature or fluctuations in paint viscosity, resulting in unstable spraying quality. This design flaw, which prevents flexible adjustment of the paint delivery speed, severely affects the coating uniformity and adhesion of the aluminum alloy disc brake hub end caps, reducing the product's corrosion resistance and aesthetics.

[0004] Secondly, while some improved spraying equipment on the market has achieved some degree of adaptation and adjustment of paint delivery speed, its simple and crude structural design and low stability still lead to many problems in practical applications. Specifically, the adjustment mechanism of such equipment usually lacks locking and anti-loosening designs; during long-term operation, the pulsating pressure generated by the paint flow inside the pipeline will continuously impact the adjustment components, gradually causing internal components to shift; at the same time, external factors such as equipment operation and accidental contact by operators can also cause slight displacement of the adjusted structure. These design deficiencies result in unpredictable changes in the adjusted paint delivery speed during actual operation, leading to uneven coating thickness, unstable surface quality, and in severe cases, even missed spraying, increasing product scrap rate and production costs. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] In view of the problems existing in the prior art, this utility model provides a spraying device for processing aluminum alloy disc brake hub end caps for two-wheeled electric vehicles, so as to solve the technical problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a spraying device for processing aluminum alloy disc brake hub end caps for two-wheeled electric vehicles, comprising a support frame, a fixing plate fixedly mounted on the outer side of the support frame, a fixing pipe and an outer pipe installed between two fixing plates, an adjusting sleeve provided between the fixing pipe and the outer pipe, the two ends of the adjusting sleeve being rotatably connected to the fixing pipe and the outer pipe respectively, an adjusting groove inclinedly opened in the fixing pipe, an adjusting plate slidably mounted in the adjusting groove, an adjusting block fixedly connected to one side of the adjusting plate, a locking sleeve slidably mounted on the outer side of the fixing pipe, and multiple movably mounted on one side of the adjusting sleeve. The locking block has a locking spring on the outside of the fixed tube, and the two ends of the locking spring are respectively connected to two adjacent locking blocks. A movable rod is fixedly connected to one side of the locking sleeve, and a movable plate is fixedly installed on the movable rod. The movable plate has two locations. A moving plate is rotatably installed on the outside of the fixed tube. The moving plate has a moving hole and a moving groove. The moving hole is connected to one end of the moving groove. An adapter is movably installed on the inside of the adjusting sleeve. An adapter groove is spirally opened on the outer wall of the adapter. An adapter block is fixed in the adjusting sleeve and slides in the adapter groove. Multiple locking blocks are fixed on the outside of the fixed tube.

[0009] This utility model is further configured such that a movable assembly is detachably mounted on the top of the support frame, multiple spray pipes are detachably mounted on one side of the movable assembly, a connecting chamber is detachably mounted on one side of the movable assembly, a flexible hose is connected to the input end of the connecting chamber, the input ends of the multiple spray pipes are respectively connected to the connecting chamber, and the other end of the flexible hose is connected to the top of the fixed pipe. A rotating assembly is detachably mounted on the inner side of the support frame, and a placement plate is detachably mounted on the top of the rotating assembly. This design achieves a reasonable configuration of the spraying system and the workpiece rotation mechanism. The detachable design of the movable assembly and multiple spray pipes facilitates the adjustment of the spraying position according to the different shapes of the wheel hub end caps. The flexible connection between the connecting chamber and the flexible hose ensures a smooth and reliable paint delivery process. At the same time, the cooperation between the rotating assembly and the placement plate allows the workpiece to rotate 360 ​​degrees in all directions, ensuring that the upper surface of the wheel hub end cap can be evenly covered during the spraying process, significantly improving the quality and efficiency of product surface treatment.

[0010] The present invention is further configured such that spraying chambers are symmetrically and detachably provided on both sides of the support frame, thereby realizing bidirectional synchronous spraying function and greatly improving processing efficiency.

[0011] The present invention is further configured such that a follower block is fixedly connected to one side of the mixing block, and a follower groove is opened at the top of the adapter. The follower block slides in the follower groove. This design constructs a precise linkage guiding mechanism. The sliding cooperation between the follower block and the follower groove ensures that the mixing block moves precisely along a predetermined trajectory during the movement, avoiding deviation or shaking during the adjustment process. At the same time, this linkage structure accurately converts the axial movement of the adapter into the radial movement of the mixing block, ensuring adjustment accuracy and repeatability, and providing a key structural guarantee for the precise control of the paint conveying speed.

[0012] The present invention is further configured such that a push spring is connected to one side of the mixing block, and a push block is connected to the other end of the push spring. The push block is movably connected to the mixing block through the push spring. A plurality of mating rods are fixedly connected to one side of the push block, and mating grooves are correspondingly opened in the mixing block. One end of the mating rod slides into the mating groove. The sliding mating structure between the mating rod and the mating groove ensures the accuracy and stability of the push block movement.

[0013] The present invention is further configured such that a sliding groove is provided on the inner wall of the fixed tube, and a sliding block is slidably provided in the sliding groove. The sliding block is fixedly connected to the outer wall of the matching device. This design constructs a stable and reliable linear guide system. The cooperation between the sliding block and the sliding groove not only restricts the rotation of the matching device and ensures that it can only move axially, but also improves the operational stability and positioning accuracy of the adjustment system.

[0014] This utility model is further configured such that the locking block has a locking groove, and multiple locking rails are fixedly provided on one side of the adjusting sleeve. The locking block is slidably installed on the outside of the locking rails through the locking groove. A locking wheel is rotatably provided on one side of the locking block. The locking wheel engages between two adjacent locking blocks. This design achieves a highly reliable positioning and locking mechanism. The sliding installation of the locking block on the locking rail through the locking groove ensures the movement stability of the locking component. The engagement connection between the locking wheel and the locking block forms a physical lock, effectively preventing the adjusting sleeve from rotating unexpectedly under external force. The rotation design of the locking wheel reduces wear during the locking process, making the operation smoother.

[0015] The present invention is further configured such that a movable spring is movably sleeved on the outer side of the movable rod, one end of the movable spring is connected to the locking sleeve, and the other end of the movable spring abuts against one side of the moving plate. This design constructs an automatic reset quick unlocking mechanism. The movable spring provides a constant reset force to the locking sleeve, ensuring that the locking sleeve can automatically return to a stable state after the locking operation is completed.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a spraying device for processing aluminum alloy disc brake hub end caps for two-wheeled electric vehicles, which has the following beneficial effects:

[0018] 1. By incorporating components such as a fixed pipe, external pipe, adjusting sleeve, mixing trough, mixing plate, mixing block, adapter, adapter trough, adapter block, push spring, and push block, this design solves the problem of inflexible adjustment of paint conveying speed in existing technologies. This innovative design employs a spiral adapter trough and adapter block mating structure. Rotating the adjusting sleeve causes the adapter block to slide within the adapter trough, thereby pushing the adapter to move the sliding block along the sliding trough. Simultaneously, the adapter pushes one side of the mixing block, enabling the mixing block, push block, push spring, and mating rod to work collaboratively to precisely control the flow area inside the fixed pipe. This multi-stage linkage precision adjustment mechanism allows the device to adjust according to different viscosities of paint. The system allows for flexible adjustment of the paint delivery speed for coatings or workpieces of different materials, effectively preventing uneven coating distribution during spraying, where some areas have excessively thick paint while others have insufficient paint. Furthermore, the adjustable mechanism allows for manual adjustments based on changes in ambient temperature or paint viscosity fluctuations. The entire system seamlessly integrates with the moving assembly, rotating assembly, spray pipe, and connecting chamber, supporting uniform spraying of the wheel hub end caps. This significantly improves the coating uniformity and adhesion of the aluminum alloy disc brake wheel hub end caps, enhancing the product's corrosion resistance and aesthetics. It provides a comprehensive solution for high-quality surface treatment of aluminum alloy disc brake wheel hub end caps for two-wheeled electric vehicles.

[0019] 2. By coordinating the locking sleeve, movable rod, movable plate, moving plate, moving hole, moving groove, locking block, locking wheel, locking block, locking rail, and locking groove, this design perfectly solves the problem that some existing devices, while capable of adapting to and adjusting the paint conveying speed, suffer from low stability. The core innovation of this design lies in its highly stable locking structure. After the paint conveying speed adjustment is completed, the locking spring pulls the locking block to slide inward along the locking rail and locking groove, causing the locking block to drive the locking wheel to engage between two adjacent locking blocks, forming a physical lock. Simultaneously, by operating the moving plate, the movable spring pushes the locking sleeve to reset, causing the movable rod and movable plate to disengage from the moving hole and moving groove, allowing the inner wall of the locking sleeve to form a second layer of limit on the outer wall of the locking wheel, thus constituting a double locking mechanism. Then, the moving plate is operated again, so that the moving hole and moving groove form a misaligned fit with the moving rod and moving plate, realizing the support and limit of the locking sleeve, achieving a third limit. This design effectively prevents the continuous impact of the pulsating pressure generated by the paint flow inside the pipeline on the adjusting components, eliminating the possibility of structural loosening and displacement; it greatly improves the structural stability of the equipment during long-term operation; the entire locking system keeps the adjusted paint delivery speed constant during actual operation, ensuring uniform coating thickness and stable surface quality, effectively avoiding phenomena such as missed spraying, reducing product scrap rate and production costs, providing a reliable guarantee for stable production and quality control of enterprises, and fully meeting the basic requirements of modern precision manufacturing for equipment stability and process consistency.

[0030] A movable assembly 21 is detachably mounted on the top of the support frame 1. Multiple spray pipes 22 are detachably mounted on one side of the movable assembly 21. A connecting chamber 23 is detachably mounted on one side of the movable assembly 21. A hose 24 is connected to the input end of the connecting chamber 23. The input ends of the multiple spray pipes 22 are respectively connected to the connecting chamber 23. The other end of the hose 24 is connected to the top of the fixed pipe 3. A rotating assembly 25 is detachably mounted on the inner side of the support frame 1. A placement tray 26 is detachably mounted on the top of the rotating assembly 25.

[0031] The support frame 1 has symmetrical and detachable spraying chambers 27 on both sides.

[0032] In this embodiment, when the device is needed, the wheel hub end cap is first clamped and fixed on the placement plate 26 using the external clamping device in the prior art. Then, the conveying device connected to the input end of the external pipe 4 is opened, so that the conveying device conveys the mixed paint into the external pipe 4. Then, it is conveyed into the connecting chamber 23 through the fixed pipe 3 and the flexible hose 24. At the same time, the two side moving assemblies 21 are opened, so that the moving assemblies 21 drive the spraying pipe 22 and other components to move and adjust the position of the spraying pipe 22. At the same time, the rotating assembly 25 is opened to drive the wheel hub end cap clamped and fixed above to rotate. Then, the paint in the connecting chamber 23 is distributed into multiple spraying pipes 22 and then atomized and sprayed out through multiple spraying pipes 22 to realize the spraying process of the wheel hub end cap.

[0033] Please see Figures 3-5As a further implementation of the overall equipment: a follower block 28 is fixedly connected to one side of the mixing block 8, and a follower groove 29 is opened at the top of the fitting 17, and the follower block 28 slides in the follower groove 29.

[0034] A push spring 30 is connected to one side of the mixing block 8, and a push block 31 is connected to the other end of the push spring 30. The push block 31 is movably connected to the mixing block 8 through the push spring 30. A plurality of mating rods 32 are fixedly connected to one side of the push block 31. A mating groove 33 is correspondingly opened in the mixing block 8, and one end of the mating rod 32 slides into the mating groove 33.

[0035] The inner wall of the fixed tube 3 is provided with a sliding groove 34, and a sliding block 35 is slidably provided in the sliding groove 34. The sliding block 35 is fixedly connected to the outer wall of the fitting 17.

[0036] The locking block 10 has a locking groove 36, and multiple locking rails 37 are fixed on one side of the adjusting sleeve 5. The locking block 10 is slidably installed on the outside of the locking rails 37 through the locking groove 36. A locking wheel 38 is rotatably provided on one side of the locking block 10, and the locking wheel 38 is engaged between two adjacent locking blocks 20.

[0037] A movable spring 39 is movably sleeved on the outer side of the movable rod 12. One end of the movable spring 39 is connected to the locking sleeve 9, and the other end of the movable spring 39 abuts against one side of the movable plate 14.

[0038] More specifically, when the conveying speed of the paint needs to be adjusted, firstly, the moving plate 14 is rotated forward, causing the moving hole 15 and the moving groove 16 to rotate forward. When the moving hole 15 rotates to a position concentric with the movable plate 13, the locking sleeve 9 is pushed upward. The locking sleeve 9 will cause one side of the movable rod 12 and the movable plate 13 to gradually slide through the moving hole 15, and the locking sleeve 9 will cooperate with the moving plate 14 to compress the movable spring 39. When the movable spring 39 is compressed to its limit, the movable plate 13, located in the middle of the movable rod 12, just slides through the moving hole 15 and moves to the other side of the moving plate 14. Then, the moving plate 14 is rotated in the opposite direction, causing the moving hole 15 and the moving groove 16 to rotate in the opposite direction. The rod 12 will enter the moving groove 16, and then the moving rod 12, together with the moving plate 13 in its middle section, will limit the locking sleeve 9 to one side of the moving plate 14, so that the inner wall of the locking sleeve 9 no longer limits the outer wall of the locking wheel 38. Then, the adjusting sleeve 5 will rotate in the forward direction, and the adjusting sleeve 5 will drive the locking rail 37 on one side to rotate. Then, the locking rail 37 will drive the locking block 10 to rotate in the forward direction through the locking groove 36. Then, the locking block 10 will drive the locking wheel 38, which is rotated on one side, to move out from between the two locking blocks 20. The locking block 10 will also drive the locking block 10 to slide outward along the locking rail 37 and the locking groove 36. Then, the locking block 10 will drive the locking spring 11 to stretch outward. At the same time, the adjusting sleeve 5 will drive the inner adapter block 19 to slide along the adapter groove 18. The spiral structure design of the matching groove 18, along with the sliding block 35 and sliding groove 34, limits the rotation of the adapter 17, preventing it from rotating. The adapter 17 then drives the outer matching groove 18 and the outer sliding block 35 to slide along the sliding groove 34. Simultaneously, the adapter 17 pushes one side of the adjusting block 8 to slide. The adjusting block 8 then moves one side of the mating rod 32, mating groove 33, push spring 30, and push block 31. The adjusting block 8 also drives the other side of the adjusting plate 7 to slide along the inclined adjusting groove 6. As the adjusting plate 7 slides along the adjusting groove 6, it pulls the adjusting block 8 inwards, causing it to pull one side of the follower block 28 to slide inwards along the follower groove 29. Step 8 will cause the other side's push spring 30, push block 31, mating rod 32, and mating groove 33 to converge inwards. Then, multiple push blocks 31 will abut together. Then, the matching sleeve 17 will continue to push the adjusting block 8 to move, and the distance between the adjusting block 8 and the push block 31 will decrease, causing the push spring 30 to be compressed to a certain extent. At the same time, the mating rod 32 connected to one end of the push block 31 will slide into the mating groove 33. The change in the gap of the push spring 30 and the inward movement of the adjusting block 8 reduce the flow area inside the fixed tube 3, changing the paint's passing speed and achieving adjustment of the paint conveying speed. When it is necessary to expand the flow area inside the fixed tube 3, simply rotate the adjusting sleeve 5 in the reverse direction according to the above steps. When the paint conveying speed is adjusted appropriately, stop rotating the adjusting sleeve 5.The locking rail 37, through the locking groove 36, moves the locking block 10 and the locking wheel 38 between the corresponding two locking blocks 20. Then, the locking spring 11 resets and pulls the locking block 10 to slide inward along the locking rail 37 and the locking groove 36, causing the locking block 10 to drive one side of the locking wheel 38 to engage between the corresponding two locking blocks 20. Then, the moving plate 14 is rotated forward again, causing the moving plate 14 to drive the moving hole 15 and the moving groove 16 to rotate forward again. When the moving hole 15 rotates to the position concentric with the movable plate 13, the movable spring 39 pushes the locking sleeve 9 to slide back to its original position. Then, the locking sleeve 9 drives the movable rod 12 and the two movable plates 13 to slide back to their original positions. When the movable spring 39 is fully reset, the movable plate 13 at the top of the movable rod 12 moves back to the original position of the moving plate 14. On this side, the movable rod 12 is no longer in the moving hole 15 and the moving groove 16. Then, the moving plate 14 is rotated in the opposite direction to reset, causing the moving plate 14 to drive the moving hole 15 and the moving groove 16 to rotate and reset to a position that does not correspond to the movable rod 12 and the moving plate 13. Then, the movable rod 12 and the moving plate 13 at its top support the locking sleeve 9 to one side of the moving plate 14, making it impossible for the locking sleeve 9 to slide easily. Then, the inner wall of the locking sleeve 9 limits the outer wall of the locking wheel 38, making it impossible for the locking wheel 38 and the locking block 10 to move outward. Thus, through the cooperation of the locking groove 36 and the locking rail 37, the rotation of the adjusting sleeve 5 is limited, preventing the adjusting sleeve 5 from rotating. This ensures the structural stability after the paint conveying speed is adjusted, thereby ensuring stable conveying of the paint after the paint conveying speed is adjusted.

[0039] In summary, when the equipment is in use or operation: First, the wheel hub end cover is clamped and fixed on the placement plate 26 using the external clamping device in the prior art. Then, the conveying device connected to the input end of the external pipe 4 is opened, so that the conveying device delivers the mixed paint into the external pipe 4. Then, it is delivered to the connecting chamber 23 through the fixed pipe 3 and the flexible hose 24. At the same time, the two moving assemblies 21 are opened, so that the moving assemblies 21 drive the spraying pipe 22 and other components to move and adjust the position of the spraying pipe 22. At the same time, the rotating assembly 25 is opened to drive the wheel hub end cover clamped and fixed above to rotate. Then, the paint in the connecting chamber 23 is distributed into multiple spraying pipes 22 and then atomized and sprayed out through multiple spraying pipes 22 to achieve the spraying process of the wheel hub end cover.

[0040] When the paint conveying speed needs to be adjusted, first rotate the moving plate 14 forward, causing the moving plate 14 to drive the moving hole 15 and the moving groove 16 to rotate forward. When the moving hole 15 rotates to a position concentric with the movable plate 13, push the locking sleeve 9 upward. The locking sleeve 9 will drive the movable rod 12 and the movable plate 13 on one side to gradually slide through the moving hole 15. The locking sleeve 9 will cooperate with the moving plate 14 to compress the movable spring 39. When the movable spring 39 is compressed to its limit, the movable plate 13, which is set in the middle of the movable rod 12, just slides through the moving hole 15 and moves to the other side of the moving plate 14. Then rotate the moving plate 14 in the opposite direction, causing the moving plate 14 to drive the moving hole 15 and the moving groove 16 to rotate in the opposite direction. Then the movable rod 12 will... Entering the movable slot 16, the movable rod 12, in conjunction with the movable plate 13 in its middle section, limits the locking sleeve 9 to one side of the movable plate 14, so that the inner wall of the locking sleeve 9 no longer limits the outer wall of the locking wheel 38. Then, the adjusting sleeve 5 is rotated in the forward direction, which drives one side of the locking rail 37 to rotate. Then, the locking rail 37 drives the locking block 10 to rotate in the forward direction through the locking groove 36. Then, the locking block 10 drives the locking wheel 38, which is rotated on one side, to move out from between the two locking blocks 20. The locking block 10 will also drive the locking block 10 to slide outward along the locking rail 37 and the locking groove 36. Then, the locking block 10 will drive the locking spring 11 to stretch outward. At the same time, the adjusting sleeve 5 will drive the inner adapter block 19 to slide along the adapter groove 18. The spiral structure design of 8, along with the sliding block 35 and sliding groove 34, limits the rotation of the adapter 17, preventing it from rotating. The adapter 17 then drives the outer adapter groove 18 and the outer sliding block 35 to slide along the sliding groove 34. Simultaneously, the adapter 17 pushes one side of the adjusting block 8 to slide. The adjusting block 8 then moves one side of the mating rod 32, mating groove 33, push spring 30, and push block 31. The adjusting block 8 also drives the other side of the adjusting plate 7 to slide along the inclined adjusting groove 6. As the adjusting plate 7 slides along the adjusting groove 6, it pulls the adjusting block 8 inwards, causing it to pull one side of the follower block 28 to slide inwards along the follower groove 29. At the same time, the adjusting block 8... The push spring 30, push block 31, mating rod 32, and mating groove 33 on the other side are driven to converge inwards. Then, multiple push blocks 31 will abut together. Then, the matching sleeve 17 continues to push the adjusting block 8 to move, and the distance between the adjusting block 8 and the push block 31 will decrease, so that the push spring 30 is compressed to a certain extent. At the same time, the mating rod 32 connected to one end of the push block 31 will slide into the mating groove 33. The change in the gap of the push spring 30 and the inward movement of the adjusting block 8 reduce the flow area inside the fixed tube 3, thereby changing the paint passing speed and adjusting the paint conveying speed. When it is necessary to expand the flow area inside the fixed tube 3, simply rotate the adjusting sleeve 5 in the reverse direction according to the above steps. After the paint conveying speed is adjusted appropriately, stop rotating the adjusting sleeve 5.The locking rail 37, through the locking groove 36, moves the locking block 10 and the locking wheel 38 between the corresponding two locking blocks 20. Then, the locking spring 11 resets and pulls the locking block 10 to slide inward along the locking rail 37 and the locking groove 36, causing the locking block 10 to drive one side of the locking wheel 38 to engage between the corresponding two locking blocks 20. Then, the moving plate 14 is rotated forward again, causing the moving plate 14 to drive the moving hole 15 and the moving groove 16 to rotate forward again. When the moving hole 15 rotates to the position concentric with the movable plate 13, the movable spring 39 pushes the locking sleeve 9 to slide back to its original position. Then, the locking sleeve 9 drives the movable rod 12 and the two movable plates 13 to slide back to their original positions. When the movable spring 39 is fully reset, the movable plate 13 at the top of the movable rod 12 moves back to the original position of the moving plate 14. On this side, the movable rod 12 is no longer in the moving hole 15 and the moving groove 16. Then, the moving plate 14 is rotated in the opposite direction to reset, causing the moving plate 14 to drive the moving hole 15 and the moving groove 16 to rotate and reset to a position that does not correspond to the movable rod 12 and the moving plate 13. Then, the movable rod 12 and the moving plate 13 at its top support the locking sleeve 9 to one side of the moving plate 14, making it impossible for the locking sleeve 9 to slide easily. Then, the inner wall of the locking sleeve 9 limits the outer wall of the locking wheel 38, making it impossible for the locking wheel 38 and the locking block 10 to move outward. Thus, through the cooperation of the locking groove 36 and the locking rail 37, the rotation of the adjusting sleeve 5 is limited, preventing the adjusting sleeve 5 from rotating. This ensures the structural stability after the paint conveying speed is adjusted, thereby ensuring stable conveying of the paint after the paint conveying speed is adjusted.

For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
