Description

Technical Field

[0001] This utility model relates to the technical field of automatic oiling devices for cylinder liner processing, and in particular to an automatic oiling device for cylinder liner processing. Background Technology

[0002] The automatic oiling device for cylinder liner machining is an automated equipment designed specifically for the needs of rust prevention, lubrication and surface protection during cylinder liner machining (such as after honing and precision boring to before assembly). Through the collaboration of mechanical structure and control system, it replaces manual oiling operations. Its core objective is to improve oiling uniformity, efficiency and production stability.

[0003] The applicant discovered through a search that a Chinese patent, "An Automatic Oiling Device for Cylinder Liner Machining," with publication number CN220027624U, mainly uses a clamping mechanism to clamp cylinder liners of different sizes from the inside. This eliminates the need to replace other devices and avoids affecting the exterior of the cylinder liner, thus reducing costs and improving work efficiency. However, this patent cannot coat the inner wall of the cylinder liner with a comprehensive and uniform oil film. In actual use, if the oil film is not fully covered, the metal surface of the missed areas is directly exposed to the air and is prone to oxidation and corrosion due to contact with moisture and dust. Corrosion will damage the precision-machined surface of the inner wall, and in severe cases, reprocessing or direct scrapping may be necessary. Therefore, we propose an automatic oiling device for cylinder liner machining. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic oiling device for cylinder liner processing, so as to solve the problem mentioned in the background art that it is impossible to apply an oil film with full coverage and uniform thickness to the inner wall of the cylinder liner. In actual use, if the oil film coverage is not complete, the metal surface of the missed area is directly exposed to the air, which is prone to oxidation and corrosion due to contact with moisture and dust. The corrosion will damage the precision machined surface of the inner wall, and in severe cases, it is necessary to reprocess or scrap it directly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic oiling device for cylinder liner processing, comprising a worktable and a cylinder liner body, with support frames fixedly connected to the top left and right sides of the worktable, a groove provided on the top of the worktable, and an oiling assembly provided on the top of the worktable, the oiling assembly comprising a first motor, a guide rod and an oil pump, the first motor being connected to a moving block and a load-bearing plate via a lead screw, the oil pump being connected to a spray plate and an annular nozzle via an output pipe, and the oil pump being connected to an oil storage tank via an input pipe.

[0006] As a preferred embodiment, the first motor is fixedly installed on the top of the left support frame, the upper end of the lead screw is fixedly connected to the output end of the first motor, the lower end of the lead screw is rotatably connected to the bottom inner wall of the left support frame, the outer wall of the lead screw is rotatably connected to the top inner wall of the left support frame, and the guide rod is fixedly connected to the upper and lower inner walls of the right support frame.

[0007] As a preferred embodiment, the movable blocks are provided in two sets. One set of movable blocks is threaded to the outer wall of the lead screw, and the other set of movable blocks is slidably connected to the outer wall of the guide rod. The corresponding sides of the two sets of movable blocks are respectively fixedly connected to the two sides of the load-bearing plate. The oil pump is fixedly connected to the top center of the load-bearing plate, and one end of the output pipe is fixedly connected to the output end of the oil pump.

[0008] As a preferred embodiment, the other end of the output pipe is fixedly connected to the inside of the spray plate, and multiple sets of annular nozzles are provided. The multiple sets of annular nozzles are circumferentially distributed and fixedly connected to the outer wall of the spray plate. One end of the input pipe is fixedly connected to the input end of the oil pump, and the other end of the input pipe is fixedly connected to the inside of the oil storage tank. The oil storage tank is also fixedly installed on the top of the load-bearing plate and located behind the oil pump.

[0009] As a preferred embodiment, the top and bottom of the worktable are provided with rotating fixing components. The rotating fixing components include a second motor, a servo motor, and an arc-shaped clamping plate. The second motor is fixedly connected to the bottom of the worktable, and a drive rod is fixedly connected to the output end of the second motor. The drive rod is rotatably connected to the inner wall of the bottom of the worktable. A turntable is fixedly connected to the upper end of the drive rod. A positioning groove is opened on the top of the turntable. The cylinder liner body is disposed inside the positioning groove. Two sets of connecting plates are fixedly connected to the top of the turntable.

[0010] As a preferred embodiment, the servo motor is fixedly connected to the surface of a set of connecting plates, and a bidirectional screw is fixedly connected to the output end of the servo motor. The end of the bidirectional screw away from the servo motor is rotatably connected to the inner wall of another set of connecting plates, and the outer wall of the bidirectional screw is rotatably connected to the inner wall of a set of connecting plates.

The inner wall of the arc-shaped clamp is in contact with the outer wall of the cylinder liner body.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. Using the set oiling components, the operator starts the first motor to drive the lead screw to rotate. Two sets of moving blocks drive the load-bearing plate to move vertically, which in turn drives the spray plate and the annular nozzles to be aligned with the oiling area on the inner wall of the cylinder liner body. Multiple sets of annular nozzles distributed in a circle receive the oil pump through the spray plate and can spray oil synchronously from multiple directions. Combined with the lifting and lowering of the load-bearing plate, an oil film with full coverage and uniform thickness can be formed on the inner wall of the cylinder liner body. The oil film thickness deviation can be controlled within a very small range, thereby effectively avoiding subsequent problems caused by local lack of oil on the inner wall of the cylinder liner body.

[0013] 2. Using the set rotating fixing component, the operator starts the servo motor to drive the bidirectional screw to rotate. The two sets of arc-shaped clamps move inward synchronously along the slide bar, clamping the outer wall of the cylinder liner body evenly from both sides to achieve stable positioning and prevent displacement during oiling. At the same time, the second motor drives the turntable to rotate through the drive rod, and the fixed cylinder liner body rotates synchronously. In coordination with the lifting and lowering of the annular nozzle of the oiling component, the oil forms a spiral covering trajectory along the inner wall of the cylinder liner body, avoiding uneven thickness of the oil film in some areas and achieving uniform oiling in the entire circumference.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see the appendix Figure 1 Appendix Figure 3 and appendix Figure 4 An automatic oiling device for cylinder liner machining includes a worktable 1 and a cylinder liner body 3. Support frames 2 are fixedly connected to the left and right sides of the top of the worktable 1. A groove 4 is formed in the top of the worktable 1. An oiling assembly 5 is installed on the top of the worktable 1. The oiling assembly 5 includes a first motor 501, a guide rod 505, and an oil pump 506. The first motor 501 is connected to a moving block 503 and a load-bearing plate 504 via a lead screw 502. The oil pump 506 is connected to a... The spray plate 508 and the annular nozzle 509 are connected to the oil pump 506 via the input pipe 510, and the oil storage tank 511 is connected to the oil pump 506. The first motor 501 is fixedly installed on the top of the left support frame 2. The upper end of the lead screw 502 is fixedly connected to the output end of the first motor 501. The lower end of the lead screw 502 is rotatably connected to the bottom inner wall of the left support frame 2. The outer wall of the lead screw 502 is rotatably connected to the top inner wall of the left support frame 2. The guide rod 505 is fixedly connected to the upper and lower inner walls of the right support frame 2.

[0024] The load-bearing plate 504 supports the functional components required for oiling and moves up and down with the lead screw 502 under the drive of the moving block 503, realizing the position adjustment of the entire oiling assembly 5. The guide rod 505 cooperates with the right moving block 503 to provide guidance for the up and down movement of the load-bearing plate 504 and restricts the moving block 503 to slide only along the axial direction of the guide rod 505, preventing the load-bearing plate 504 from swaying or rotating left and right due to the gap of the lead screw 502 when it is raised and lowered.

[0025] Two sets of movable blocks 503 are provided. One set of movable blocks 503 is threaded to the outer wall of the lead screw 502, and the other set of movable blocks 503 is slidably connected to the outer wall of the guide rod 505. The corresponding sides of the two sets of movable blocks 503 are respectively fixedly connected to the two sides of the load-bearing plate 504. The oil pump 506 is fixedly connected to the top center of the load-bearing plate 504. One end of the output pipe 507 is fixedly connected to the output end of the oil pump 506, and the other end of the output pipe 507 is fixedly connected to the inside of the spray plate 508. Multiple sets of annular nozzles 509 are provided. Multiple sets of annular nozzles 509 are circumferentially distributed and fixedly connected to the outer wall of the spray plate 508. One end of the input pipe 510 is fixedly connected to the input end of the oil pump 506, and the other end of the input pipe 510 is fixedly connected to the inside of the oil storage tank 511. The oil storage tank 511 is also fixedly installed on the top of the load-bearing plate 504 and located behind the oil pump 506.

[0026] The oil tank 511 is used to store the oil used for oiling and to provide a continuous oil source for the entire oiling assembly 5. An oil delivery pipe is provided on the top of the oil tank 511, through which workers can deliver the oil used for oiling into the oil tank 511.

[0027] Specifically, through the oiling assembly 5, the operator starts the first motor 501 to drive the lead screw 502 to rotate. The two sets of moving blocks 503 drive the load-bearing plate 504 to move vertically, so that the spray plate 508 and the annular nozzle 509 are aligned with the area to be oiled on the inner wall of the cylinder liner body 3. The multiple sets of annular nozzles 509 receive the oil delivered by the oil pump 506 through the spray plate 508 and spray oil synchronously from multiple directions. Combined with the lifting and lowering of the load-bearing plate 504, a fully covered and uniformly thick oil film is formed on the inner wall of the cylinder liner body 3. The oil film thickness deviation can be controlled within a very small range to avoid local oil shortage on the inner wall of the cylinder liner body 3.

[0028] Please see the appendix Figure 1 and appendix Figure 5 -Appendix Figure 7The top and bottom of the worktable 1 are equipped with a rotating fixing assembly 6, which includes a second motor 601, a servo motor 606, and an arc-shaped clamping plate 608. The second motor 601 is fixedly connected to the bottom of the worktable 1, and a drive rod 602 is fixedly connected to the output end of the second motor 601. The drive rod 602 is rotatably connected to the inner wall of the bottom of the worktable 1. A turntable 603 is fixedly connected to the upper end of the drive rod 602. A positioning groove 604 is opened on the top of the turntable 603, and the cylinder liner body 3 is set inside the positioning groove 604. Two sets of connecting plates 605 are fixedly connected to the top of the turntable 603. The servo motor 606... A bidirectional screw 607 is fixedly connected to the output end of a servo motor 606, which is fixedly connected to the surface of a set of connecting plates 605. The end of the bidirectional screw 607 away from the servo motor 606 is rotatably connected to the inner wall of another set of connecting plates 605, and the outer wall of the bidirectional screw 607 is rotatably connected to the inner wall of a set of connecting plates 605. A slide rod 609 is fixedly connected to one side surface of the two sets of connecting plates 605. One end of the arc-shaped clamp 608 is threaded to the outer wall of the bidirectional screw 607, and the other end of the arc-shaped clamp 608 is slidably connected to the outer wall of the slide rod 609. The inner wall of the arc-shaped clamp 608 is in contact with the outer wall of the cylinder liner body 3.

[0029] The turntable 603 serves as the support platform for the cylinder liner body 3. It rotates synchronously with the drive rod 602 and fixes the cylinder liner body 3 through the positioning groove 604 and the arc-shaped clamping plate 608 on the top, so that it follows the rotation.

[0030] Specifically, through the set rotating fixing component 6, the operator starts the servo motor 606 to drive the bidirectional screw 607 to rotate. The two sets of arc-shaped clamping plates 608 move inward synchronously along the slide bar 609, clamping the outer wall of the cylinder liner body 3 from both sides to achieve positioning and prevent displacement during oiling. At the same time, the second motor 601 drives the turntable 603 to rotate through the drive rod 602. The fixed cylinder liner body 3 rotates synchronously, which cooperates with the lifting and lowering of the annular nozzle 509 of the oiling component 5 to make the oil form a spiral covering trajectory along the inner wall of the cylinder liner body 3, avoiding uneven oil film thickness and achieving uniform oiling.

[0031] Working principle of this utility model: This utility model is an automatic oiling device for cylinder liner processing. First, the operator places the cylinder liner body 3 into the positioning groove 604 on the top of the turntable 603. Then, the operator starts the servo motor 606, which drives the bidirectional screw 607 to rotate. The two sets of arc-shaped clamping plates 608 move inward synchronously along the slide rod 609 under the drive of the bidirectional screw 607 until the inner wall is in close contact with the outer wall of the cylinder liner body 3, thus clamping and fixing the workpiece from both sides. Next, the operator starts the first motor 501, which drives the lead screw 502 to rotate. The moving block 503, which is threaded to the lead screw 502, drives the load-bearing plate 504 to move in the vertical direction. At the same time, the right moving block 503 slides synchronously along the guide rod 505 until the spray plate 508 and the annular nozzle 509 below the load-bearing plate 504 are aligned with the cylinder. The oiling area on the inner wall of the cylinder liner body 3 is adjusted to be oiled. Then, the operator starts the oil pump 506. The oil pump 506 draws oil from the oil tank 511 through the input pipe 510 and delivers it to the spray plate 508 through the output pipe 507. The spray plate 508 then distributes the oil to multiple sets of circumferentially distributed annular nozzles 509. The oil is sprayed out synchronously from the annular nozzles 509. At the same time, the operator starts the second motor 601. The second motor 601 drives the turntable 603 to rotate through the drive rod 602. The cylinder liner body 3, which is fixed by the arc-shaped clamp 608, rotates synchronously with the turntable 603. The first motor 501 continues to drive the load-bearing plate 504 to slowly rise and fall. The annular nozzles 509 move with the load-bearing plate 504. Combined with the rotation of the cylinder liner body 3, the oil forms a spiral covering trajectory along the inner wall of the workpiece, and finally forms a uniform oil film on the inner wall of the cylinder liner body 3.

[0032] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
