Description

Technical Field

[0001] This invention relates to the field of aluminum casting surface treatment technology, specifically to a cylindrical lightweight aluminum casting surface treatment device. Background Technology

[0002] Against the backdrop of the rapid development of the intelligent manufacturing equipment industry, cylindrical lightweight aluminum castings, with their advantages of light weight, good strength adaptability, and high forming efficiency, are widely used in various fields such as automobiles, aerospace, and electronic equipment. The forming of these castings mostly relies on die casting or gravity casting processes. During production, the mold must be designed with a detachable structure to facilitate demolding after casting. The parting line naturally forms on the casting surface at the mold closing point. Due to the flow characteristics of molten metal within the mold, differences in cooling rates, and limitations in mold closing accuracy, continuous flash often remains at the parting line. This flash not only affects the appearance of the casting but also interferes with subsequent assembly accuracy and may even detach during use, posing a safety hazard. Therefore, removing parting line flash is an indispensable and critical step in the surface treatment of cylindrical lightweight aluminum castings, typically requiring specialized grinding to completely remove it and ensure the quality and performance of the casting.

[0003] Existing surface treatment equipment for cylindrical lightweight aluminum castings has many significant drawbacks, making it difficult to meet the demands of large-scale, high-precision production. Most existing equipment requires manual removal of the formed casting from the mold followed by manual grinding, a cumbersome and time-consuming process. During grinding, manual operation is difficult to align with the parting line, easily leading to grinding deviations and accidental grinding of other surfaces, causing scratches and damage that affect the casting's appearance and structural integrity. Furthermore, the consistency of manual operation is extremely poor; different operators apply varying grinding force and angles, resulting in inconsistent flash removal. Some castings have incomplete flash removal, while others are over-ground, increasing subsequent repair processes and reducing production efficiency, failing to meet the demands of the intelligent manufacturing equipment industry for efficient and precise production. Summary of the Invention

[0004] The purpose of this invention is to provide a surface treatment device for cylindrical lightweight aluminum castings, which solves the problem mentioned in the background art that the existing surface treatment devices for cylindrical lightweight aluminum castings require manual removal of the aluminum casting from the bottom mold and then manual grinding, which is cumbersome and inefficient. Manual grinding is difficult to accurately align with the parting line, which can easily lead to deviations and accidental grinding of other surfaces of the casting, causing surface scratches and damage. At the same time, different operators have different strengths and angles, resulting in inconsistent flash removal effects, with problems of incomplete removal or over-grinding.

[0009] Furthermore, a limiting rod is slidably installed inside the fixed frame, and a rotating seat is fixedly installed at one end of the limiting rod near the grinding wheel. Rotating columns on both sides of the grinding wheel are slidably installed inside the rotating seat, and a drive motor is fixedly installed at the top of the rotating seat. The output end of the drive motor is coaxially and fixedly connected to the rotating column at the top of the grinding wheel.

[0010] Furthermore, a rotating frame is vertically fixed to the end of the limiting rod away from the rotating seat, one end of the threaded rod is rotatably engaged inside the top of the rotating frame, an auxiliary rod is fixedly installed on the outside of the rotating frame away from the top of the threaded rod, a fixing block is fixedly installed on the outside of the top of the fixing frame, and one end of the auxiliary rod is slidably installed inside the fixing block.

[0011] Furthermore, a compression spring is sleeved on the outside of the auxiliary rod, and the two ends of the compression spring are respectively fixedly installed on the outside of the fixed block and the outside of the rotating frame. A rotating handle is fixedly installed on the end of the threaded rod away from the rotating frame.

[0012] Furthermore, the spraying assembly includes a storage tank, a rotating disk, and a spray head. The storage tank is fixed on the outside of the slider near the rotating handle. The rotating disk is fixedly installed on the outside of the rotating column at the bottom of the grinding wheel. The spray head is located on one side of the grinding wheel. The top of the storage tank is fixedly connected to an injection pipe.

[0013] Furthermore, a limit post is fixed at the bottom edge of the rotating disk, and a reciprocating frame is sleeved and slidably engaged on the outside of the limit post. A support block is fixed at the bottom of the rotating seat, and a piston rod is slidably installed through the inside of the support block.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. Through the configuration of the positioning and grinding components, this device enables automated clamping, lifting, and precise grinding of cylindrical lightweight aluminum castings. It eliminates the need for manual removal and grinding, improving production efficiency. The first cylinder in the positioning component drives the positioning blocks to move in opposite directions, working in conjunction with the friction head at the corner of the positioning blocks to firmly clamp the casting and prevent slippage during clamping, ensuring precise grinding. The threaded rod and rotating handle in the grinding component allow for flexible adjustment of the grinding wheel position to accommodate wear and grinding requirements of different castings. The stepper motor drives the lead screw to move the slider and grinding wheel smoothly, achieving precise linear grinding of the parting line and avoiding accidental grinding of other surfaces of the casting. This ensures the cleanliness and structural integrity of the casting, meeting the high-efficiency and precise production needs of the intelligent manufacturing equipment industry.

[0016] 2. By adjusting the settings of the grinding and spraying components, this device can achieve integrated operation of casting grinding and surface rust prevention during use, eliminating the need for additional drive structures and rust prevention processes, thus further improving production efficiency. After the grinding component is adjusted to accurately remove the flash from the parting line, the spraying component can simultaneously and accurately spray the rust-preventive liquid. The spray head is aimed at the grinding area to ensure that the exposed metal substrate after grinding is promptly covered by the rust-preventive liquid, forming a dense protective film that effectively isolates corrosive media, prevents oxidation and rusting of castings, and extends the service life of castings. At the same time, the rust-preventive liquid can fill the tiny scratches after grinding, improving the surface smoothness of castings. The overall design is adapted to the large-scale, high-quality production needs of the intelligent manufacturing equipment industry, solving the defect of the existing device where grinding and protection are disconnected.

[0020] Example 1: Please refer to Figures 1-8 A surface treatment device for cylindrical lightweight aluminum castings includes a manufacturing equipment table 1 and a limiting frame 2 placed on the top of the manufacturing equipment table 1. Guide rods 4 slide through the corners of the limiting frame 2, and the bottom ends of the guide rods 4 are fixedly installed on the outside of the top of the manufacturing equipment table 1.

[0021] The positioning block 5 is arranged in an inverted T shape, and friction heads 36 are threadedly connected to the corners of the positioning block 5.

[0022] Each of the two lead screws 7 has a sprocket 8 fixedly fitted on one end. A chain 9 is fitted between the two sprockets 8 for transmission. A stepper motor 10 is fixedly installed on one side of the limiting frame 2. The output end of the stepper motor 10 is coaxially fixedly connected to one end of one of the lead screws 7.

[0023] The adjusting grinding assembly includes a fixed frame 12, a grinding wheel 15, and a threaded rod 18. The fixed frame 12 is fixedly installed on the outside of the slider 11 near the positioning block 5. The grinding wheel 15 is located on the outside of the fixed frame 12 away from the slider 11. The threaded rod 18 passes through and is threadedly installed inside the slider 11.

[0024] A limiting rod 13 is slidably installed inside the fixed frame 12. A rotating seat 14 is fixedly installed at one end of the limiting rod 13 near the grinding wheel 15. Rotating columns on both sides of the grinding wheel 15 are installed through and rotatably inside the rotating seat 14. A drive motor 16 is fixedly installed at the top of the rotating seat 14. The output end of the drive motor 16 is coaxially and fixedly connected to the rotating column at the top of the grinding wheel 15.

[0025] The end of the limiting rod 13 away from the rotating seat 14 is vertically fixed to the rotating frame 17. One end of the threaded rod 18 is rotatably engaged inside the top of the rotating frame 17. An auxiliary rod 20 is fixedly installed on the outside of the rotating frame 17 away from the top of the threaded rod 18. A fixing block 19 is fixedly installed on the outside of the top of the fixing frame 12. One end of the auxiliary rod 20 is slidably installed inside the fixing block 19.

[0026] A compression spring 21 is sleeved on the outside of the auxiliary rod 20. The two ends of the compression spring 21 are fixedly installed on the outside of the fixed block 19 and the outside of the rotating frame 17, respectively. A rotating handle 22 is fixedly installed on the end of the threaded rod 18 away from the rotating frame 17.

[0027] In this embodiment, the working principle of the cylindrical lightweight aluminum casting surface treatment device is designed around the integrated, efficient, and precise production needs of the intelligent manufacturing equipment industry. It realizes fully automated operations of casting, clamping, lifting, grinding, and adjustable grinding position without much manual intervention. The specific working process is as follows: First, the device is installed and fixed as a whole. The casting mold of the cylindrical lightweight aluminum casting is placed at the top center of the manufacturing equipment platform 1, so that the mold can be directly cast on the device without the need for additional mold transfer. This achieves seamless connection between casting and surface treatment, greatly improves production efficiency, and meets the core needs of large-scale production in the intelligent manufacturing equipment industry.

[0028] After the cylindrical lightweight aluminum casting has been cast in the mold, the existing mold opening mechanism pulls the upper mold open, exposing the cylindrical lightweight aluminum casting above the bottom mold, eliminating the need for manual removal. Then, the first cylinders 3 on both sides of the limiting frame 2 are activated. The output ends of the first cylinders 3 push the positioning blocks 5 to move towards each other. The positioning blocks 5 are arranged in an inverted T shape, and the friction heads 36 with threaded connections at their corners increase the friction with the casting surface, ensuring stable clamping of both ends of the cylindrical lightweight aluminum casting and preventing slippage during clamping, thus laying the foundation for subsequent precise grinding.

[0029] After clamping is completed, the second cylinders 6 on both sides of the bottom of the manufacturing equipment platform 1 are activated. The output end of the second cylinder 6 extends upward, pushing the limiting frame 2 to slide upward along the guide rod 4. The guide rod 4 guides and limits the lifting of the limiting frame 2, preventing the limiting frame 2 from tilting during the lifting process. This, in turn, drives the cylindrical lightweight aluminum casting clamped by the positioning block 5 to be lifted synchronously and smoothly until the casting is completely separated from the bottom mold. This process does not require manual transfer of the casting, which reduces the labor intensity of the operators and avoids the problem of scratches and bumps on the surface of the casting during manual transfer, ensuring the integrity of the casting surface.

[0030] After the casting is lifted into position, the stepper motor 10 on one side of the limiting frame 2 is activated. The output end of the stepper motor 10 drives one of the lead screws 7 to rotate at a constant speed. Since sprockets 8 are fixed to the outside of one end of both lead screws 7, and a transmission chain 9 is sleeved between the two sprockets 8, when one lead screw 7 rotates, it will drive the other lead screw 7 to rotate synchronously in the same direction through the transmission action of the sprocket 8 and the chain 9. When the two lead screws 7 rotate synchronously, the slider 11, which is threadedly connected to the lead screw 7, will move smoothly along the sliding engagement direction of the limiting frame 2. The sliding engagement connection between the slider 11 and the limiting frame 2 ensures that the slider 11 does not deviate or wobble during movement, thereby driving the adjustment and grinding assembly fixed to one side of the slider 11 to move synchronously.

[0031] Simultaneously, the drive motor 16 at the top of the rotating seat 14 is activated. The output of the drive motor 16 drives the grinding wheel 15 to rotate at high speed. The grinding wheel 15 moves smoothly along a straight line with the slider 11, precisely grinding the flash at the parting line of the cylindrical lightweight aluminum casting. Compared with the existing manual grinding method, this structure realizes the automated operation of straight grinding, eliminating the need for manual grinding and casting transfer. This not only greatly improves the efficiency of flash removal but also avoids the problems of difficulty in aligning with the parting line and accidental grinding of other surfaces of the casting during manual grinding. It effectively prevents scratches and damage to the surface of the casting, ensuring the cleanliness and structural integrity of the casting, while ensuring the consistency of flash removal effect, meeting the high-precision production needs of the intelligent manufacturing equipment industry. In the future, the vacuum cleaner head of the existing vacuum cleaner can be added to the slider 11 to enable vacuuming during grinding.

[0032] Before or during grinding, if the grinding wheel 15 wears or the casting specifications change slightly, and the grinding position needs to be adjusted, the handle 22 can be manually rotated in both directions to rotate the threaded rod 18 inside the slider 11. Since one end of the threaded rod 18 is rotated and engaged inside the top of the rotating frame 17, the rotation of the threaded rod 18 will push the rotating frame 17 to move along the length of the auxiliary rod 20. The auxiliary rod 20 is slidably installed inside the fixed block 19, which can guide and limit the movement of the rotating frame 17, prevent the rotating frame 17 from deviating when it moves, and ensure the accuracy of the grinding wheel 15 position adjustment.

[0033] When the rotating frame 17 moves, it will drive the limiting rod 13 to move synchronously. The limiting rod 13 is slidably installed inside the fixed frame 12, which in turn drives the rotating seat 14 and the grinding wheel 15, which are fixedly connected to one end of the limiting rod 13, to move laterally. This achieves a slight and precise adjustment of the position of the grinding wheel 15, which can not only compensate for the grinding deviation caused by the wear of the grinding wheel 15, but also adapt to the parting line grinding requirements of cylindrical lightweight aluminum castings of different specifications, ensuring the grinding effect and grinding accuracy.

[0034] Example 2: Please refer to Figure 4 , Figure 9 and Figure 10 This embodiment further describes Example 1. The spraying assembly includes a storage tank 24, a rotating disk 25, and a spray head 35. The storage tank 24 is fixed on the outside of the slider 11 near the rotating handle 22. The rotating disk 25 is fixedly installed on the outside of the rotating column at the bottom of the grinding wheel 15. The spray head 35 is located on one side of the grinding wheel 15. The top of the storage tank 24 is fixedly connected to an injection pipe 23.

[0035] A limit post 26 is fixed at the bottom edge of the rotating disk 25. A reciprocating frame 27 is sleeved and slidably engaged on the outside of the limit post 26. A support block 29 is fixed at the bottom of the rotating seat 14. A piston rod 28 is slidably installed through the inside of the support block 29. A piston cylinder 30 is fixed on one side of the support block 29. The piston end of the piston rod 28 is slidably sealed inside the piston cylinder 30. The other end of the piston rod 28 is fixedly installed in the middle of one side of the reciprocating frame 27. A sliding frame 31 is slidably sleeved on the outside of the piston cylinder 30. One end of the sliding frame 31 is fixedly installed on the outside of one side of the fixed frame 12.

[0036] The piston cylinder 30 is fixedly connected to a one-way inlet valve pipe 32 and a one-way outlet valve pipe 33 at the end away from the piston rod 28. The input end of the one-way inlet valve pipe 32 is fixedly connected to the inside of the storage tank 24. The output end of the one-way outlet valve pipe 33 is fixedly connected to a stretching hose 34. The end of the stretching hose 34 away from the one-way outlet valve pipe 33 is fixedly connected to the input end of the spray head 35.

[0037] In this embodiment, when the device enters the grinding operation stage, that is, when the drive motor 16 at the top of the rotating seat 14 is started in embodiment one, driving the grinding wheel 15 to rotate at high speed, and the stepper motor 10 drives the lead screw 7 to rotate, driving the slider 11 and the adjusting grinding assembly to move in a straight line to grind the parting line flash of the casting, the liquid spraying assembly is started synchronously. There is no need to start other drive structures, achieving seamless coordination between grinding and liquid spraying. Since the rotating disk 25 is fixedly installed outside the rotating column at the bottom of the grinding wheel 15, the rotation of the grinding wheel 15 will drive the rotating disk 25 to rotate synchronously. The design of synchronous rotation of the rotating disk 25 and the grinding wheel 15 ensures that the liquid spraying action is in sync with the grinding action, avoiding the problem of not spraying liquid in time after grinding and the oxidation of the casting surface.

[0038] When the rotating disk 25 rotates, the limiting post 26 fixed at its bottom edge will move in a circular motion with the rotating disk 25. The reciprocating frame 27 is sleeved and slidably engaged with the limiting post 26. The circularly moving limiting post 26 will continuously push the reciprocating frame 27 to make a lateral reciprocating motion. A piston rod 28 is fixedly installed in the middle of one side of the reciprocating frame 27. The other end of the piston rod 28 is slidably installed inside the support block 29, and the piston end of the piston rod 28 is slidably sealed inside the piston cylinder 30. Therefore, when the reciprocating frame 27 makes a lateral reciprocating motion, it will drive the piston rod 28 to make a reciprocating extension and retraction motion inside the piston cylinder 30, realizing negative pressure suction and positive pressure discharge inside the piston cylinder 30.

[0039] When the piston rod 28 moves away from the piston cylinder 30, a negative pressure is formed inside the piston cylinder 30, and the rust-preventive liquid inside the storage tank 24 is drawn into the piston cylinder 30 through the one-way inlet valve pipe 32; when the piston rod 28 moves closer to the piston cylinder 30, a positive pressure is formed inside the piston cylinder 30, and the rust-preventive liquid inside the piston cylinder 30 is delivered to the stretch hose 34 through the one-way drain valve pipe 33.

[0040] The end of the stretch hose 34 away from the one-way drain valve 33 is fixedly connected to the input end of the spray head 35. The stretch hose 34 can flexibly adapt to the movement of the grinding components, avoiding hose breakage due to pulling, and ensuring stable delivery of the rust inhibitor to the spray head 35. The spray head 35 is located on one side of the grinding wheel 15, which can accurately spray the rust inhibitor onto the parting line area and surrounding surface of the casting after grinding by the grinding wheel 15, realizing simultaneous grinding and rust prevention. When the metal substrate on the surface of the casting is just exposed after grinding, it can be quickly covered by the rust inhibitor, forming a dense rust-preventive protective film, effectively isolating corrosive media such as air and moisture, preventing oxidation and rust on the surface of the casting, and extending the storage period and service life of the casting. At the same time, the rust inhibitor can fill any tiny scratches that may exist on the surface after grinding, further improving the smoothness of the casting surface, preventing the subsequent stress expansion of tiny scratches, eliminating the need for additional rust prevention treatment processes, and greatly improving production efficiency.

[0041] When the casting grinding operation is completed and a reset operation is required, the drive motor 16 must be stopped first. After the drive motor 16 stops running, the grinding wheel 15 and the rotating disk 25 stop rotating synchronously. The limit post 26 no longer pushes the reciprocating frame 27 to move. The piston rod 28 stops its reciprocating extension and retraction movement inside the piston cylinder 30. The liquid spraying assembly then stops its liquid spraying operation. After that, the control screw 7 rotates in the opposite direction, driving the slider 11 to reset.

[0042] This reset control logic can effectively prevent the spraying component from running continuously during the reset process, avoiding the waste of spraying rust inhibitor when there is no grinding operation. At the same time, it can prevent components such as piston rod 28 and reciprocating frame 27 from running meaninglessly during reset, reducing component wear, extending the service life of the spraying component, and further improving the practicality and stability of the device.
