Description

Technical Field

[0001] The utility model belongs to the technical field of cylinder liner processing, and specifically relates to an automatic oiling device for cylinder liner processing. Background Technique

[0002] During the processing of the cylinder liner, it is necessary to apply oil to the inner wall of the cylinder liner, so as to evenly apply a thin layer of grease on the inner wall of the cylinder liner, avoid rust caused by long-term contact with air, and at the same time be used for lubricating the piston.

[0003] Chinese Patent with the publication number of CN220027624U discloses an automatic oiling device for cylinder liner processing, including an outer frame. A clamping mechanism is arranged inside the outer frame, and a disassembly and assembly mechanism is arranged inside the outer frame. The clamping mechanism includes a linear guide rail I. The outer wall of the linear guide rail I is fixedly connected to the top end of the inner wall of the outer frame. A linear slider I is arranged inside the linear guide rail I. The bottom end of the linear slider I is fixedly connected to a connecting column. The outer wall of the connecting column is fixedly connected to a motor, and the driving end of the motor is fixedly connected to a connecting disc.

[0004] Although the device of the above application oils the cylinder liner through an oiling mechanism, the angle of the oiling mechanism cannot be adjusted, resulting in uneven thickness of the oiling layer on the inner wall and bottom of the cylinder liner, which reduces the service life of the cylinder liner to a certain extent. In addition, only the spring drives the clamping block to clamp the cylinder liner, and the cylinder liner is very easy to shake during the oiling process, making it difficult to ensure the quality of oiling.

[0005] In view of this, the present utility model is specifically proposed. Content of the Utility Model

[0006] The technical problem to be solved by the present utility model is to overcome the deficiencies of the prior art and provide an automatic oiling device for cylinder liner processing.

[0007] To solve the above technical problem, the basic concept of the technical solution adopted by the present utility model is:

[0008] An automatic oiling device for cylinder liner processing, including a workbench. Columns are installed in the middle of the opposite sides of the workbench. A cross bar is slidably fitted inside the opposite inner sides of the two columns. An oiling component is installed in the middle of the lower side of the cross bar. A disc is rotatably fitted in the middle of the upper side of the workbench. A cylinder liner is installed on the upper side of the disc. A clamping component corresponding to the circumferential side of the cylinder liner is installed on the disc;

[0009] The oiling assembly includes a concave support column fixed to the middle of the lower side of the cross bar, an oiling disc rotatably fitted to the lower end of the concave support column, a rod fixed to the top inside the concave support column, and a rope wound around the circumference of the rod. The two ends of the rope are respectively fixed to the opposite ends on the upper side of the oiling disc, and the oiling disc is located above the cylinder sleeve and corresponds to the inside of the cylinder sleeve.

[0010] Optionally, a screw rod is rotatably fitted to the middle of one of the columns, one end of the cross bar is in threaded fit with the circumference of the screw rod, and a rod is installed in the middle of the other column. The other end of the cross bar is slidably fitted to the circumference of the rod.

[0011] By providing the cross bar, the oiling assembly can be driven to move up and down on the relative inner sides of the two columns, so that the oiling assembly can be adjusted to the optimal position suitable for oiling according to the cylinder sleeves of different heights, preparing for the next step of oiling the cylinder sleeves by the oiling assembly.

[0013] By providing the first motor, the screw rod can be driven to rotate, so that the screw rod is in threaded fit with one end of the cross bar and drives the cross bar to move up and down. Thus, the cross bar drives the oiling assembly to move up and down synchronously, realizing the position adjustment of the oiling assembly. By providing the second motor, the rod can be driven to rotate, so that the rod drives the oiling disc to rotate synchronously, thus preparing for the next step of oiling the inner wall or bottom of the cylinder sleeve.

[0014] Optionally, the oiling disc includes an oil receiving disc rotatably fitted to the lower end of the concave support column, a plurality of oil leakage holes opened on the lower side of the oil receiving disc, and an oiling brush installed on the lower side of the oil receiving disc corresponding to the plurality of oil leakage holes. The oiling brush corresponds to the inside of the cylinder sleeve.

[0015] By providing a plurality of oil leakage holes on the lower side of the oil receiving disc, the oil in the oil storage tank can flow uniformly to the circumference of the oiling brush through the plurality of oil leakage holes, facilitating uniform oiling of the inner wall and bottom of the cylinder sleeve.

[0016] Optionally, an oil storage tank is installed at one end of the upper side of the workbench. An oil outlet is opened in the middle of the rear side of the oil storage tank. A valve is provided at the oil outlet. A guide oil pipe is installed in the oil outlet. One end of the guide oil pipe is connected to the oil receiving disc and corresponds to the plurality of oil leakage holes.

[0017] By setting a valve at the oil outlet, the flow rate of the oil in the storage tank can be controlled, thereby preventing the flow rate of the oil from being too fast or too slow, which may cause uneven oil coating thickness on the inner wall and bottom of the cylinder liner. This further improves the oil coating quality. And through the arranged oil guide pipe, the oil in the storage tank can be introduced into the oil receiving tray through the oil guide pipe, preparing for the next step of oil coating on the inner wall and bottom of the cylinder liner by the oil coating brush.

The second arc-shaped clamping plate is slidably matched with the upper side of the disc.

[0019] By arranging the electric guide rail, the second arc-shaped clamping plate can be driven to move horizontally on the upper side of the disc, so that the second arc-shaped clamping plate moves towards the side close to the first arc-shaped clamping plate, thereby realizing clamping and fixing of cylinder liners with different cylinder diameters, and further improving the stability of the cylinder liner during oil coating.

[0020] Optionally, the relative inner sides of the first arc-shaped clamping plate and the second arc-shaped clamping plate correspond to the circumferential side of the cylinder liner. A third motor is fixed in the middle of the lower side of the workbench, and the output end of the third motor is fixed to the central part of the lower side of the disc.

[0021] By arranging the third motor, the disc can be driven to rotate, so that the disc drives the clamped and fixed cylinder liner to rotate synchronously, and thus the oil coating disc can quickly coat the inner wall or bottom of the rotating cylinder liner, further improving the oil coating efficiency of the device.

[0022] After adopting the above technical solutions, the present utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the present utility model does not necessarily need to achieve all the advantages described below at the same time:

[0023] 1. By arranging the clamping assembly, cylinder liners with different cylinder diameters can be clamped and fixed, effectively preventing the cylinder liner from shaking during the oil coating process, which may cause uneven oil coating. Thus, the oil coating quality and the stability of the cylinder liner are improved. And through the rope wound around the circumferential side of the rod body, one end of the rope pulls up one end of the oil coating disc, which can change the inclination angle between the oil coating disc and the concave support column, thereby adjusting the oil coating disc to the best angle suitable for coating the inner wall or bottom of the cylinder liner, better uniformly coating the inner wall and bottom of the cylinder liner, effectively reducing the unevenness of the oil coating layer thickness on the inner wall and bottom of the cylinder liner, and at the same time improving the service life of the cylinder liner.

[0024] 2. The provided disc can drive the clamped cylinder liner to rotate, enabling the oiling disc at the adjusted angle to oil the inner wall or bottom of the rotating cylinder liner, effectively improving the oiling efficiency.

SPECIFIC IMPLEMENTATION MANNERS

[0034] Now, the present utility model will be further described in detail with reference to the attached drawings.

[0035] Please refer to Figures 1-5As shown in the figure, in this embodiment, an automatic oiling device for cylinder liner processing is provided, including: a workbench 1, cylinders 2 are installed in the middle of the opposite sides of the workbench 1, a cross bar 3 is slidably fitted to the inner sides of the two cylinders 2, an oiling assembly 4 is installed in the middle of the lower side of the cross bar 3, a disk 5 is rotatably fitted to the middle of the upper side of the workbench 1, a cylinder liner 6 is installed on the upper side of the disk 5, and a clamping assembly corresponding to the circumferential side of the cylinder liner 6 is installed on the disk 5;

[0036] The oiling assembly 4 includes a concave support column 7 fixed to the middle of the lower side of the cross bar 3, an oiling disk 8 rotatably fitted to the lower end of the concave support column 7, a rod fixed to the inner top of the concave support column 7, and a rope 9 wound around the circumferential side of the rod. The two ends of the rope 9 are respectively fixed to the opposite ends of the upper side of the oiling disk 8, and the oiling disk 8 is located above the cylinder liner 6 and corresponds to the inner side of the cylinder liner 6.

[0037] The working principle of this device: When it is necessary to oil the inner wall and bottom of the cylinder liner 6, first place the cylinder liner 6 on the upper side of the disk 5. After placing it, start the clamping assembly. At this time, the clamping assembly clamps and fixes the placed cylinder liner 6, realizing the clamping and fixing of cylinder liners 6 with different cylinder diameters. After the clamping and fixing are completed, move the cross bar 3 downward. At this time, the cross bar 3 drives the oiling assembly 4 to slide and fit on the inner sides of the two cylinders 2. At the same time, the lower end of the oiling disk 8 extends into the inside of the cylinder liner 6 and fits against the bottom of the cylinder liner 6. Then open the valve. At this time, the oil in the oil storage tank 17 is introduced into the lower end of the oiling disk 8 through the oil guide pipe 18. At the same time, rotate the disk 5. At this time, the disk 5 drives the clamped cylinder liner 6 to rotate synchronously. At this time, the lower end of the oiling disk 8 oils the bottom of the rotating cylinder liner 6. After the bottom is oiled, stop rotating the disk 5. Then rotate the rod, so that the rod drives the rope 9 to wind around the circumferential side of the rod and pull up one end of the oiling disk 8, thereby changing the inclination angle between the oiling disk 8 and the concave support column 7, realizing the angle adjustment of the oiling disk 8. At the same time, rotate the disk 5. Then the oiling disk 8 with the adjusted angle oils the inner wall of the rotating cylinder liner 6. After the inner wall is oiled, close the valve, thereby realizing the oiling work on the inner wall and bottom of the cylinder liner 6.

[0038] As Figure 2 shown, a screw rod 10 is rotatably fitted to the middle of one cylinder 2 of this embodiment. One end of the cross bar 3 is threadedly fitted to the circumferential side of the screw rod 10. A rod 11 is installed in the middle of the other cylinder 2. The other end of the cross bar 3 is slidably fitted to the circumferential side of the rod 11; As Figure 1 shown, a first motor 12 is fixed to the upper side of one cylinder 2 of this embodiment. The output end of the first motor 12 is fixed to the upper end of the screw rod 10. A second motor 13 is fixed to the middle of one side of the concave support column 7. The output end of the second motor 13 is fixed to one end of the rod.

[0039] When it is necessary to adjust the position of the oiling tray 8, first start the first motor 12. The output end of the first motor 12 drives the screw rod 10 to rotate, so that the screw rod 10 is in threaded cooperation with one end of the cross bar 3, thereby driving the cross bar 3 to move downward on the relative inner sides of the two columns 2. At this time, the other end of the cross bar 3 is slidably fitted on the circumferential side of the rod body 11, realizing the adjustment of the position of the oiling tray 8.

[0040] When it is necessary to adjust the angle of the oiling tray 8, start the second motor 13. The output end of the second motor 13 drives the rod body to rotate, so that the rod body drives the rope 9 to wind around the circumferential side of the rod body and pull up one end of the oiling tray 8, thereby changing the inclination angle between the oiling tray 8 and the concave support column 7, realizing the adjustment of the angle of the oiling tray 8.

[0041] As Figure 4 shown, the oiling tray 8 of this embodiment includes an oil receiving tray 14 rotatably fitted at the lower end of the concave support column 7, a plurality of oil leakage holes 15 opened on the lower side of the oil receiving tray 14, and an oiling brush 16 installed on the lower side of the oil receiving tray 14 corresponding to the plurality of oil leakage holes 15. The oiling brush 16 corresponds to the inner side of the cylinder sleeve 6; As Figure 1 shown, at one end of the upper side of the workbench 1 of this embodiment, an oil storage tank 17 is installed. A central part at the rear side of the oil storage tank 17 is provided with an oil outlet. A valve is provided at the oil outlet, and a guide oil pipe 18 is installed in the oil outlet. One end of the guide oil pipe 18 is connected to the oil receiving tray 14 and corresponds to the plurality of oil leakage holes 15.

[0042] When it is necessary to oil the inner wall and bottom of the cylinder sleeve 6, open the valve. At this time, the oil in the oil storage tank 17 is introduced into the guide oil pipe 18 through the oil outlet. At the same time, the oil flows along the guide oil pipe 18 to the oil receiving tray 14. At this time, the oil uniformly flows to the circumferential side of the oiling brush 16 through the plurality of oil leakage holes 15. Then start the third motor 22. The output end of the third motor 22 drives the disc 5 to rotate. At this time, the disc 5 drives the clamped cylinder sleeve 6 to rotate synchronously. Thus, the lower end of the oiling brush 16 oils the bottom or inner wall of the rotating cylinder sleeve 6. After the bottom or inner wall is oiled, close the valve, realizing the oiling work on the inner wall and bottom of the cylinder sleeve 6.

[0043] As Figure 5 shown, the clamping assembly of this embodiment includes a first arc-shaped clamping plate 19 fixed at one end of the upper side of the disc 5, an electric guide rail 20 installed in the middle of the disc 5, and a second arc-shaped clamping plate 21 fixed at the output end of the electric guide rail 20. The second arc-shaped clamping plate 21 is slidably fitted on the upper side of the disc 5; As Figure 1 shown, the relative inner sides of the first arc-shaped clamping plate 19 and the second arc-shaped clamping plate 21 of this embodiment both correspond to the circumferential side of the cylinder sleeve 6. A third motor 22 is fixed in the middle of the lower side of the workbench 1. The output end of the third motor 22 is fixed to the central part of the lower side of the disc 5.

[0044] When it is necessary to clamp and fix the cylinder liner 6, first place the cylinder liner 6 on the upper side of the disc 5. After the placement is completed, start the electric guide rail 20, and the output end of the electric guide rail 20 drives the second arc-shaped clamping plate 21 to move towards the side close to the first arc-shaped clamping plate 19. Thus, the second arc-shaped clamping plate 21 and the first arc-shaped clamping plate 19 clamp and fix the circumferential side of the placed cylinder liner 6, realizing the clamping and fixing of cylinder liners 6 with different cylinder diameters.
