Description

Technical Field

[0001] This utility model relates to the field of cylinder polishing technology, and more specifically to a cylinder casting channel fluid polishing device. Background Technology

[0002] As the core component of an internal combustion engine, the engine block has an extremely complex internal structure, filled with numerous internal channels such as main oil passages, branch oil passages, and water passages for lubrication and cooling. After casting, these channels will have a large amount of flash, burrs, and adhering molding sand remaining on their inner walls, and their surface roughness often does not meet the design requirements.

[0003] If these defects are not thoroughly cleaned, during engine operation, the detached metal shavings and abrasive particles will circulate randomly with the oil, severely scratching the surfaces of precision friction pairs such as crankshaft, bearings, and cylinder walls, and even clogging small oil passages, leading to lubrication failure and causing serious engine malfunctions such as cylinder scoring and bearing seizure.

[0004] A search revealed Chinese patent CN219685033U, which discloses a polishing device for the inner wall of an engine cylinder. This device can adjust the polishing plate according to the diameter of the engine cylinder to polish the inner wall of engine cylinders of different specifications, increasing the convenience of the device. However, it uses a special tool with a guide strip to process straight pipes such as the main oil passage. This method is not only inefficient, but also completely ineffective for curved channels and intersecting holes. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a cylinder casting channel fluid polishing device to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a cylinder casting channel fluid polishing device, including a base, vertical guide rails fixedly connected to the inner walls of both sides of the base, a slide frame slidably connected between the vertical guide rails on both sides via a sliding sleeve, multiple arc-shaped plates fixedly connected to both sides of the slide frame, ring frames fixedly connected to the ends of multiple arc-shaped plates on the same side, slide seats passing through and slidably connected to two ring frames, a connecting frame fixedly connected to the bottom end of the slide seat, bushings fixedly connected to multiple holes on the connecting frame, joints fixedly connected to multiple bushings, and L-shaped plates fixedly connected to the upper surfaces of the arc-shaped plates located in the middle position on both sides of the slide frame, and a cylinder two for sliding the slide seat up and down fixedly connected to one side of the L-shaped plate.

[0007] As a further embodiment of this utility model, both sides of the base are provided with clearance openings, and both outer walls of the base are fixedly connected with cylinders that enable the slide to slide up and down along the vertical guide rail.

[0008] As a further embodiment of this utility model, a clamping frame for pressing and fixing the cylinder casting is fixedly connected to the lower surface of the slide, and a rubber pad is adhered to the lower surface of the clamping frame.

[0009] As a further embodiment of this utility model, the bottom inner wall of the base is provided with a contoured groove that has the same shape as the bottom of the cylinder casting.

[0012] As a further embodiment of this utility model, the ends of multiple connectors on the same side are connected to the inlet pipe for conveying polishing fluid medium from the outside, while multiple connectors on the other side are connected to the outlet pipe from the outside.

[0013] As a further embodiment of this utility model, when the clamping frame is in close contact with the upper surface of the cylinder casting, the multiple joints are aligned with the multiple holes of the cylinder casting.

[0014] The technical effects and advantages of this utility model are as follows:

[0017] 3. This utility model achieves rapid and initial positioning of the cylinder casting by using a contoured groove that matches the shape of the base bottom and the cylinder bottom, along with the surrounding limiting frame.

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Reference Figures 1-4 This utility model provides a fluid polishing device for a cylinder casting channel, including a base 1. Vertical guide rails 2 are fixedly connected to the inner walls of both sides of the base 1 by bolts. A slide frame 4 is slidably connected between the vertical guide rails 2 on both sides by a sliding sleeve. Multiple arc plates 8 are fixedly connected to both sides of the slide frame 4 by bolts. Ring frames 9 are fixedly connected to the ends of multiple arc plates 8 on the same side by bolts. Slide seats 11 are slidably connected to both ring frames 9. A connecting frame 12 is fixedly connected to the bottom end of the slide seat 11 by bolts. Liner rings 14 are fixedly connected to multiple holes on the connecting frame 12 by bolts. Joints 15 are fixedly connected to multiple liner rings 14 by bolts. L-shaped plates 10 are fixedly connected to the upper surface of the arc plates 8 located in the middle position on both sides of the slide frame 4 by bolts. A cylinder 2 13 that causes the slide seat 11 to slide up and down is fixedly connected to one side of the L-shaped plate 10 by bolts.

[0025] Specifically, after the cylinder casting is placed, cylinder 5, which is fixed on both sides of the base 1, is started simultaneously. The piston rod of cylinder 5 retracts, which drives the slide 4 to move smoothly downward along the vertical guide rails 2 on both sides. Then, cylinder 13 is started to extend its piston rod, which moves the connecting frame 12 downward through the slide 11 until the multiple joints 15 on the connecting frame 12 are inserted into the cylinder hole.

[0026] The inlet pipe connected to multiple connectors 15 on one side is connected to an external high-pressure material supply system to transport polishing fluid medium mixed with fine abrasive. The connector 15 on the other side is connected to the return pipe. The high-pressure polishing fluid is forcibly injected into the corresponding internal channel of the cylinder from the connector 15 on one side. Under high pressure, the fluid carries the abrasive and flows at high speed through every bend and intersection of the channel. The abrasive produces continuous cutting, squeezing and grinding action on the burrs, flash and rough surface of the inner wall of the channel.

[0027] By integrating multiple connectors 15 through the connecting frame 12 and linking them with the cylinder 2 drive component, all connectors 15 can be controlled to descend synchronously. After one clamping, multiple channels on the cylinder body can be connected simultaneously, and synchronous polishing of multiple channels can be achieved, which greatly improves production efficiency and can effectively handle curved channels and cross holes.

[0028] In this utility model, both sides of the base 1 are provided with clearance openings 3, and both sides of the outer wall of the base 1 are fixedly connected with cylinders 5 that enable the slide 4 to slide up and down along the vertical guide rail 2 by bolts.

[0029] It should be noted that cylinders 13 and 5 are both power actuators that convert the pressure energy of compressed air into mechanical energy. By controlling the gas inlet and outlet, they drive the piston to perform linear reciprocating motion. They can be used in conjunction with magnetic switches, proximity switches, or photoelectric switches to achieve precise control of the extension and retraction displacement of the cylinder piston rod. Those skilled in the art can set these parameters according to actual needs, which will not be elaborated here.

[0030] Furthermore, the lower surface of the slide 4 is fixedly connected with a clamping frame 6 to clamp and fix the cylinder casting by bolts, and a rubber pad is adhered to the lower surface of the clamping frame 6.

[0031] Furthermore, when the clamping frame 6 is in close contact with the upper surface of the cylinder casting, the multiple joints 15 are aligned with the multiple holes of the cylinder casting.

[0032] Specifically, as the slide 4 descends, the clamping frame 6 fixed to its lower surface descends accordingly. The rubber pad on the lower surface of the clamping frame 6 first contacts the upper surface of the cylinder casting and applies pressure, firmly pressing the cylinder into the contoured groove 7 to prevent it from moving during subsequent processing. Since the clamping frame 6 has fixed the cylinder in advance, it ensures that the various channel openings on the cylinder and the multiple joints 15 descending can be accurately aligned.

[0033] Preferably, the bottom inner wall of the base 1 is provided with a contoured groove 7 that has the same shape as the bottom of the cylinder casting.

[0034] Furthermore, a limit frame 18 is fixedly connected to the bottom inner wall of the base 1 and the outer edge of the contoured groove 7 by bolts.

[0035] First, the cylinder casting to be polished is placed in the contour groove 7 at the bottom of the base 1. The shape of the contour groove 7 matches the bottom of the cylinder and works together with the surrounding limiting frame 18 to achieve the initial rapid positioning and limiting of the cylinder.

[0036] The contoured groove 7, which matches the shape of the bottom of the base 1 and the bottom of the cylinder, and the surrounding limiting frame 18 work together to achieve rapid and initial positioning of the cylinder casting. Combined with the secondary clamping and fixing by the downward movement of the clamping frame 6, the accuracy of the workpiece position is doubled, ensuring that multiple joints 15 are aligned with the cylinder hole positions, which greatly improves clamping efficiency and positioning accuracy.

[0037] In this utility model, a pressure ring 16 with a matching groove shape on the edge of the cylinder casting hole is fixedly connected to the outer circumference of the bushing 14 by bolts. A sealing ring 17 is provided on the lower surface of the pressure ring 16 and the connection part between the joint 15 and the cylinder casting hole.

[0038] The pressure ring 16 is embedded in the groove at the edge of the cylinder bore under pressure, and forms a tight and reliable seal through the sealing ring 17, creating a closed chamber for the high-pressure circulation of the polishing fluid.

[0039] Sealing rings 17 are provided at the connection part of the connector 15 and on the lower surface of the pressure ring 16. The design of the pressure ring 16 matches the shape of the groove on the edge of the cylinder bore, forming multiple seals. This effectively prevents leakage of the high-pressure polishing fluid medium during processing, ensuring polishing pressure and thus ensuring processing effect, while avoiding media pollution of the environment and equipment.

[0040] Preferably, the ends of multiple connectors 15 on the same side are connected to the inlet pipe for conveying polishing fluid medium to the outside, while the multiple connectors 15 on the other side are connected to the outlet pipe to the outside.

[0041] The use of this utility model involves the following steps:

[0042] S1: First, place the cylinder casting to be polished into the contour groove 7 at the bottom of the base 1. The shape of the contour groove 7 matches the bottom of the cylinder and works together with the surrounding limiting frame 18 to achieve the initial rapid positioning and limiting of the cylinder.

[0043] S2: After the casting cylinder body is placed, the cylinder 5 fixed on both sides of the base 1 is started simultaneously. The piston rod of the cylinder 5 retracts, which drives the slide 4 to move smoothly downward along the vertical guide rails 2 on both sides. As the slide 4 moves downward, the clamping frame 6 fixed on its lower surface also moves down. The rubber pad on the lower surface of the clamping frame 6 first contacts the upper surface of the cylinder casting and applies pressure to firmly press the cylinder body into the contoured groove 7 to prevent it from moving in subsequent processing. Since the clamping frame 6 has fixed the cylinder body in advance, it ensures that the various channel openings on the cylinder body and the multiple joints 15 moving downward can be accurately aligned.

[0044] S3: Then, cylinder 13 is extended, and the connecting frame 12 is moved downward through the slide 11 until the multiple joints 15 on the connecting frame 12 are inserted into the cylinder hole. The pressure ring 16 is embedded in the groove on the edge of the cylinder hole under pressure, and a tight and reliable seal is formed through the sealing ring 17, which establishes a closed chamber for the high-pressure circulation of the polishing fluid.

[0045] S4: The inlet pipe connected to multiple connectors 15 on one side is connected to the external high-pressure material supply system to transport polishing fluid medium mixed with fine abrasive. The connector 15 on the other side is connected to the return pipe. The high-pressure polishing fluid is forcibly injected into the corresponding internal channel of the cylinder from the connector 15 on one side. Under high pressure, the fluid carries the abrasive and flows at high speed through every bend and intersection of the channel. The abrasive produces continuous cutting, squeezing and grinding action on the burrs, flash and rough surface of the inner wall of the channel.

[0046] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
