[0028] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0029] The first implementation method:

[0030] Figure 1-6 A surface treatment device for hydraulic cylinder production is shown, including a treatment platform, a driving motor 1 and an air pump 2 located in front of the driving motor 1 are installed on one side of the top of the treatment platform, the output end of the driving motor 1 is connected to the driving gear 3, a rotating rod 4 is arranged in front of the driving gear 3, the surface of the rotating rod 4 is fixedly sleeved with a driven gear 6 meshing with the driving gear 3, the end of the rotating rod 4 is fixedly sleeved with a grinding disc 8, the interior of the grinding disc 8 is provided with a rectangular frame groove, the interior of the rectangular frame groove is slidably connected with a separation block 81, the surface of the rotating rod 4 is provided with a strip groove, and the interior of the strip groove is arranged A small electric telescopic rod 5 is installed, and the tail end of the small electric telescopic rod 5 and the inside of the rectangular frame groove are connected with a telescopic unit 9, the telescopic unit 9 includes an outer rod 91, the inner wall of the outer rod 91 is provided with a magnetic coating, the inner part of the outer rod 91 is slidably connected with a magnetic blocking plate 92, and a movable top rod 93 is installed on the top of the magnetic blocking plate 92, and an air delivery pipe 11 is arranged through the inner center position of the rotating rod 4, and a plurality of branch pipes are connected to the tail end of the air delivery pipe 11, and the tail ends of the plurality of branch pipes extend to the inside of the outer rod 91 respectively, and a polishing arc sheet 7 is connected to the tail end of the movable top rod 93 in the strip groove.

[0031] A symmetrically arranged electric guide rail 10 is installed on the top of the processing platform, and the electric guide rail 10 is located on one side of the rotating rod 4. The inside of the electric guide rail 10 is slidably connected to a clamping frame, and the top of the clamping frame is connected to a clamping hoop 12. The center of the clamping hoop 12 is on the same horizontal axis as the center of the grinding disc 8 and the rotating rod 4.

[0032] Specifically, when grinding and polishing the inner wall of the hydraulic cylinder barrel, the barrel is first placed inside the clamping hoop 12 and clamped by the clamping hoop 12, and then the barrel is moved to the position of the grinding disc 8 with the assistance of the electric guide rail 10, so that the bottom wall of the barrel (that is, the part perpendicular to the inner wall of the barrel) is in contact with the surface of the grinding disc 8, and at the same time, the top of the grinding arc piece 7 is not in contact with the inner wall of the barrel;

[0033] After that, the electronic valve on the branch pipe surface connected to the grinding arc piece 7 needs to be started, so that the air pump 2 can deliver gas to the outer rod 91 located in the strip groove through the delivery air pipe 11, and the magnetic attraction plate 92 in the outer rod 91 can be driven up by the pressure, and then the movable push rod 93 can be driven up, until the grinding arc piece 7 is in contact with the inner wall of the cylinder, and then the electronic valve there is closed, at which time the surface of the grinding arc piece 7 facing away from the drive motor 1 is in contact with the bottom wall of the cylinder;

[0034] Then, the driving motor 1 is started, and the driving gear 3 and the driven gear 6 drive the rotating rod 4 to rotate, thereby driving the grinding arc sheet 7 and the grinding disc 8 to rotate at the same time, achieving a corresponding grinding effect. Since the side surface of the grinding arc sheet 7 facing away from the driving motor 1 is in contact with the bottom wall of the cylinder after the initial adjustment position of the grinding arc sheet 7, the bottom wall of the cylinder can be covered and polished in a circular manner;

[0035] After the initial position of the grinding arc piece 7 is polished, it is necessary to start the small electric telescopic rod 5 to make the grinding arc piece 7 approach the direction of the driving motor 1, and then the inside of the cylinder is subjected to additional polishing treatment. However, in this process, the electronic valve on the surface of the branch pipe in the rectangular frame groove is synchronously started to supply air to the inner and outer rods 91 of the rectangular frame groove to lift the separation block 81. As the rotating rod 4 rotates, the bottom wall of the cylinder can be subjected to an enlarged polishing treatment.

[0036] In summary, with the help of the small electric telescopic rod 5 and the telescopic unit 9, the present invention can realize adaptive grinding treatment of cylinders with different inner diameters, and can also give full coverage grinding treatment to the bottom wall of the cylinder, thereby improving the efficiency of surface treatment.

[0037] The depth of the strip groove is smaller than the radius of the rotating rod 4 . In the initial state, the end of the grinding arc sheet 7 away from the driving motor 1 and the surface of the grinding disc 8 away from the driving motor 1 are in the same vertical plane.

[0038] Specifically, the size design of the strip groove and the rotating rod 4 can avoid the strip groove and the air delivery pipe 11 being located on different installation surfaces, so as not to cause interference during operation.

[0039] A control cabinet is installed on the top of the processing platform, and the top of the control cabinet is connected to the bottom of the driving motor 1. A control module, an image recognition module, an image collection module and a suction module are installed inside the control cabinet. The image collection module is embedded on the surface of the movable top rod 93 near the top. An electronic valve is installed on the surface of each branch pipe, and the image collection module, the electronic valve and the small electric telescopic rod 5 are all connected to the control module signal.

[0040] Specifically, the control module is used to control the opening and closing of multiple electronic valves and a small electric telescopic rod 5. During the grinding process, the suction module can be used to suck out the grinding debris in the cylinder to ensure the cleanliness of the working surface during grinding in the cylinder. At the same time, the image collection module can be used to collect and process the image of the inside of the cylinder after grinding, and the collected image data can be transmitted to the image recognition module to determine whether the degree of grinding is qualified. After the grinding is qualified, the electronic valve and the small electric telescopic rod 5 on the surface of the branch pipe are selectively started, the position of the grinding arc piece 7 and the separation block 81 are adjusted, and the grinding position is switched.

[0041] The magnetic coating and the magnetic blocking plate 92 attract each other, and the attractive force between the magnetic coating and the magnetic blocking plate 92 in the telescopic unit 9 in the rectangular frame groove is not less than the sum of the gravity of the magnetic blocking plate 92, the movable top rod 93 and the separation block 81, and the attractive force between the magnetic coating and the magnetic blocking plate 92 in the telescopic unit 9 in the strip groove is not less than the sum of the gravity of the magnetic blocking plate 92, the movable top rod 93 and the polishing arc sheet 7.

[0042] Specifically, the magnetic attraction can prevent the grinding arc piece 7 or the separation block 81 from sliding down and extending naturally due to gravity when the grinding arc piece 7 or the separation block 81 moves to the lower position of the rotating rod 4, thereby ensuring the stability of the position of the grinding arc piece 7 and the separation block 81.

[0043] The second implementation method:

[0044] Figure 7-10 It is shown that a movable groove is provided at the bottom of the separation block 81, and an airbag cover 131 and a compression spring 134 are respectively installed on both sides of the inner wall of the movable groove. An isolation plate 132 is connected to the surface of the airbag cover 131 on one side close to the compression spring 134, and an exhaust pipe 133 is installed through the top of the airbag cover 131, and a control valve connected to the control module signal is installed on the surface of the exhaust pipe 133.

[0045] Auxiliary branch pipes 13 are installed on the surfaces of the two branch pipes in the rectangular frame groove. The tail ends of the auxiliary branch pipes 13 are installed in the interior of the airbag cover 131, and valves connected to the control module signal are installed on the surfaces of the auxiliary branch pipes 13. In the initial state, the outer rod 91 is located in the middle of the movable groove and the compression spring 134 is in a compressed energy storage state.

[0046] Different from the first embodiment, in this embodiment, after the separation block 81 in the first embodiment separates from the grinding disc 8, the grinding disc 8 still adheres to the bottom wall of the cylinder, maintaining the rotational grinding operation, which can easily improve the phenomenon of over-grinding of the bottom wall of the cylinder.

[0047] Specifically, in the initial state, the air pressure inside the airbag sleeve 131 and the compression spring 134 are arranged on both sides of the outer rod 91 and form a stable clamping effect on the movable push rod 93. After the electronic valve on the branch pipe surface is subsequently opened, the separation block 81 can still be lifted by the lifting effect of the movable push rod 93;

[0048] When it is necessary to separate the separation block 81 from the grinding disc 8, it is necessary to first close the valve on the surface of the auxiliary branch pipe 13 and open the control valve on the surface of the exhaust pipe 133, so that the gas in the airbag sleeve 131 is released and compressed. Under the elastic action of the compression spring 134, the outer rod 91 and the separation block 81 are driven to move relative to the grinding disc 8, so that the separation block 81 is still in contact with the bottom wall of the cylinder for subsequent grinding, while the grinding disc 8 is separated from the bottom wall of the cylinder. In this way, in the subsequent diffusion grinding process of the separation block 81, the grinding disc 8 will not continue to grind, thereby avoiding the occurrence of over-grinding.

[0049] When the separation block 81 needs to be reset later, the control valve is closed and the valve is opened to allow the airbag sleeve 131 to be inflated and re-squeezed under the action of the isolation plate 132 until the outer rod 91 returns to its original position and the inflation can be stopped.

[0050] In summary, the present invention can adjust the position of the grinding arc piece 7 to adapt to the grinding treatment of cylinders with different inner diameters through the telescopic unit 9 and the conveying air pipe 11. When adjusting the position of the grinding arc piece 7, air is inflated into the outer rod 91 to lift the movable top rod 93, thereby achieving the purpose of adapting to different inner diameters. At the same time, during grinding, the separation block 81 and the telescopic unit 9 can be used to supplement the grinding treatment of the bottom wall of the cylinder, and the inner wall of the cylinder can be fully ground. The cooperation of the airbag sleeve 131, the exhaust pipe 133 and the compression spring 134 can be used to avoid excessive grinding accidents.

[0051] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
