Description

Technical Field

[0001] This invention relates to the field of polishing technology, and more particularly to a surface burr polishing apparatus for processing engine cooler housings. Background Technology

[0002] The engine cooler housing is a management component of the engine's heat dissipation system. To prevent detached burrs from clogging the cooling channels, the engine cooler housing needs to be polished. Magnetic polishing is generally used, where a magnetic field drives a magnetic grinding needle to move inside the housing, bringing the needle into contact with and removing the burrs. This ensures a smooth finish on the inner walls of the housing. However, because the magnet typically moves by rotation, and the housing has deep holes, blind holes, and complex internal cavities, the grinding needle cannot effectively impact the side walls and bottom, creating polishing dead zones and affecting the overall polishing effect. Summary of the Invention

[0003] The purpose of this invention is to solve the shortcomings of the prior art, which is that the presence of deep holes, blind holes and complex internal cavities on the shell makes it difficult for the grinding needle to effectively impact its side walls and bottom, easily creating polishing dead angles and affecting the polishing effect of the shell. The invention proposes a surface burr polishing device for processing engine cooler shells.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: Design a surface deburring and polishing device for machining engine cooler housings, including a base plate, a connecting shell fixedly connected to the upper surface of the base plate, the connecting shell having an opening at its upper end, a placement cylinder connected to the connecting shell via a support mechanism, a motor mounted on the upper surface of the base plate, a rotating shaft drivenly connected to the output shaft of the motor, and a permanent magnet connected to the rotating shaft via a connecting mechanism, the permanent magnet moving via an up-and-down reciprocating mechanism.

[0005] Preferably, the support mechanism includes a support ring, which is fixedly connected to the inner wall of the connecting shell, the placement cylinder is placed on the support ring, and a reinforcing rib is fixedly connected to the lower end face of the support ring, the reinforcing rib being fixedly connected to the inner wall of the connecting shell.

[0006] Preferably, a positioning post is fixedly connected to the upper end face of the connecting shell, and a fixing lug is fixedly connected to the outer wall of the placement cylinder, with the positioning post penetrating the fixing lug.

[0007] Preferably, the connecting mechanism includes a rectangular block, which is fixedly connected to the upper end of the rotating shaft. A connecting post is fixedly connected to the middle position of the lower surface of the permanent magnet. A rectangular groove is opened in the connecting post, and the rectangular block is inserted into the rectangular groove.

[0008] Preferably, the reciprocating mechanism includes a support frame, which is rotatably connected to the rotating shaft via a thrust ball bearing. The support frame is fixedly connected to the base plate. Both ends of the upper surface of the support frame are rotatably connected to threaded cylinders via bearings. Threaded cylinders are threadedly connected to the inner ends of the two threaded cylinders. Slider blocks are fixedly connected to the upper ends of the two threaded cylinders. A connecting ring is fixedly connected to the lower surface of the permanent magnet. A groove is formed on the outer ring wall of the connecting ring. The two sliders are slidably disposed in the groove. A second gear is fixedly connected to the rotating shaft. A first gear is fixedly connected to the two threaded cylinders. The two first gears mesh with the second gear respectively.

[0009] Preferably, the threads on the two threaded cylinders are reciprocating threads.

[0010] Preferably, two lifting rings are fixedly connected to the upper end of the placement cylinder.

[0011] The present invention also provides a method for using a surface deburring and polishing device for machining engine cooler housings, comprising the following steps: S1. The casing will be lifted by a crane and placed into the placement cylinder, and then the grinding needles will be poured into the placement cylinder. S2. Start the motor. The motor drives the permanent magnet to rotate. At the same time, the permanent magnet moves up and down under the action of the up and down reciprocating mechanism, causing the grinding needle to move with the change of the magnetic field. This drives the grinding needle to move up and down to grind the inner and outer walls of the shell. S3. After grinding is completed, turn off the motor, use a crane to lift the housing and remove the placement cylinder, then connect the lifting ring with a wire rope to lift the placement cylinder, remove the placement cylinder, pour out the grinding needles inside the placement cylinder, and screen the grinding needles.

[0012] The surface burr polishing device and its method for processing engine cooler housings proposed in this invention have the following advantages: By adopting a reciprocating mechanism, the permanent magnet can move up and down while rotating, allowing the grinding needle to move up and down under the influence of the magnetic field. This creates a surging effect, enabling the grinding needle to better penetrate deep holes, blind holes, and complex internal cavities, thus ensuring a clean finish. Furthermore, the grinding needle's angle and trajectory change continuously with the combined motion of the magnetic field, allowing it to contact a wider range of housing surfaces, which is beneficial for the uniformity of the polishing effect.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0016] Example 1: Refer to Figure 1-5 A surface deburring and polishing device for engine cooler housing processing includes a base plate 1, which is circular in structure. Multiple fixing holes 4 are evenly spaced around the circumference of the base plate 1 to secure the device by bolts engaging with the fixing holes 4, preventing movement during polishing. A connecting shell 2 is fixedly connected to the upper surface of the base plate 1, with an opening at the top. A placement cylinder 3 is connected inside the connecting shell 2 via a support mechanism. A motor 11 is mounted on the upper surface of the base plate 1, and a rotating shaft 15 is driven onto the output shaft of the motor 11. A permanent magnet 14 is connected to the rotating shaft 15 via a connecting mechanism. The permanent magnet 14 moves via a reciprocating mechanism. This reciprocating mechanism allows the permanent magnet 14 to move up and down simultaneously with its rotation, causing the grinding needle to move vertically under the influence of the magnetic field. This creates a surging effect, allowing the grinding needle to better penetrate deep holes, blind holes, and complex internal cavities, thus ensuring a clean finish. Furthermore, the grinding needle's constantly changing angle and trajectory due to the combined motion of the magnetic field allows it to contact a wider area of ​​the housing surface, contributing to a more uniform polishing effect.

[0017] The support mechanism includes a support ring 8, which is fixedly connected to the inner wall of the connecting shell 2. The placement cylinder 3 is placed on the support ring 8. A reinforcing rib 9 is fixedly connected to the lower end face of the support ring 8. The reinforcing rib 9 is fixedly connected to the inner wall of the connecting shell 2. The support ring 8 and the reinforcing rib 9 provide support for the placement cylinder 3 so that the placement cylinder 3 can be taken out.

[0018] Example 2: Refer to Figure 1-4 As another preferred embodiment of the present invention, based on embodiment 1, a positioning post 6 is fixedly connected to the upper end face of the connecting shell 2, and a fixing ear 5 is fixedly connected to the outer wall of the placement cylinder 3. The positioning post 6 passes through the fixing ear 5, and the positioning post 6 and the fixing ear 5 play a limiting role in the placement cylinder 3, preventing the placement cylinder 3 from rotating as the permanent magnet 14 rotates.

[0019] Example 3: Reference Figure 1-5 As another preferred embodiment of the present invention, based on embodiment 2, the connecting mechanism includes a rectangular block 21, which is fixedly connected to the upper end of the rotating shaft 15. A connecting post 20 is fixedly connected to the middle position of the lower surface of the permanent magnet 14. A rectangular groove 22 is opened in the connecting post 20. The rectangular block 21 is inserted into the rectangular groove 22. When the permanent magnet 14 moves up and down, the position of the rectangular block 21 in the rectangular groove 22 will be adjusted. At the same time, when the rotating shaft 15 rotates, it is ensured that the rotating shaft 15 can drive the permanent magnet 14 to rotate coaxially.

[0020] The reciprocating mechanism includes a support frame 23, which is rotatably connected to the rotating shaft 15 via a thrust ball bearing. The support frame 23 is fixedly connected to the base plate 1. Both ends of the upper surface of the support frame 23 are rotatably connected to threaded cylinders 10 via bearings. Threaded posts 16 are threaded into each of the two threaded cylinders 10. Slider blocks 17 are fixedly connected to the upper ends of each of the two threaded posts 16. A connecting ring 19 is fixedly connected to the lower surface of the permanent magnet 14. A groove 18 is formed on the outer ring wall of the connecting ring 19, and the two sliders 17 are slidably disposed within the groove 18. A second gear 13 is fixedly connected to the rotating shaft 15, and a first gear 10 is fixedly connected to each of the two threaded cylinders 10. 2. The two first gears 12 mesh with the second gears 13 respectively. When the motor 11 drives the rotating shaft 15 to rotate, it drives the second gears 13 to rotate. When the second gears 13 rotate, they drive the first gears 12 to rotate, thereby driving the two threaded cylinders 10. Since the upper end of the threaded column 16 is fixedly connected to the slider 17, the slider 17 cannot rotate in the slide groove 18. This adjusts the position of the threaded column 16 in the threaded cylinder 10, causing the permanent magnet 14 to move up and down. When the permanent magnet 14 rotates with the rotating shaft 15, it will drive the slider 17 to slide in the slide groove 18, ensuring that the permanent magnet 14 can rotate.

[0021] The threads on the two threaded posts 16 are reciprocating threads. The reciprocating thread design allows the motor 11 to drive the threaded posts 16 to move up and down reciprocally when it needs to rotate in both directions.

[0022] Two lifting rings 4 are fixedly connected to the upper end of the placement cylinder 3. The lifting rings 4 are used to allow steel wires or ropes to pass through, making it convenient to lift the placement cylinder 3.

[0023] Example 4: Reference Figure 1-5 As another preferred embodiment of the present invention, based on embodiment 3, the method of using the surface deburring and polishing device for machining the engine cooler housing includes the following steps: S1. The casing will be lifted by a crane and placed into the placement cylinder 3. Then, the grinding needle will be poured into the placement cylinder 3. S2. Start motor 11. Motor 11 drives permanent magnet 14 to rotate. At the same time, permanent magnet 14 moves up and down under the action of the up and down reciprocating mechanism, so that the grinding needle moves with the change of magnetic field. At the same time, it drives the grinding needle to move up and down to grind the inner and outer walls of the shell. S3. After grinding is completed, turn off motor 11, use a crane to lift the housing and remove the placement cylinder 3, then connect the lifting ring 4 with a wire rope to lift the placement cylinder 3, remove the placement cylinder 3, pour out the grinding needles inside the placement cylinder 3, and screen the grinding needles.

[0024] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
