[0043] When the present embodiment is working, the staff places the cylinder sleeve to be processed on the surface of the bottom plate 3 until it enters the motion track of the contact arc plate 56, and then starts the motor 2 51. Since the motor 2 51 is connected to the sliding ring 1 52 by a thread, the output end of the motor 2 51 rotates the sliding ring 1 52 to move away from the motor 1 41. At this time, the sliding ring 1 52 moves to drive the connecting plate 1 53 to rotate. At the same time, the connecting plate 1 53 rotates to drive the fixing block 54 to move away from the center of the motor 2 51. At the same time, the fixing block 54 moves away from the center of the motor 2 51 and drives the connecting plate 2 55 The contact arc plate 56 is supported. At this time, the contact arc plate 56 moves in the direction away from the center of the motor 2 51 under the action of the sliding ring 1 52 until it contacts and fixes the inner wall of the cylinder sleeve, thereby achieving the effect of clamping and fixing cylinder sleeves of different diameters, improving the stability and reliability of the equipment during the processing of the cylinder sleeve, and at the same time improving the processing adaptability of the equipment to cylinder sleeves of different sizes, and adapting to cylinder sleeves of various specifications, without the need to frequently change tooling, reducing downtime, and then the staff starts the grinder 2, and the output end of the grinder 2 rotates and moves in the direction close to the cylinder sleeve until it contacts and fixes the cylinder sleeve.

[0044] See also Figure 1-Figure 8On the basis of the above embodiment, in another embodiment of the present invention, a cleaning device for cleaning the surface of the cylinder sleeve is provided at the output end of the motor 41, and the cleaning device includes a linkage plate 61, which is fixedly installed at the output end of the motor 41, and a fixed platform 62 is fixedly installed on the top of the bottom plate 3, and a reciprocating screw rod 63 is rotatably penetrated on the surface of the fixed platform 62, and a fixing ring 64 is fixedly installed on the circumferential surface of the reciprocating screw rod 63, and a telescopic arc block 65 is fixedly installed on the circumferential surface of the fixing ring 64, and a cleaning cylinder 66 is rotatably installed on the surface of the telescopic arc block 65, and a convex disc 67 is fixedly installed on the circumferential surface of the reciprocating screw rod 63, and a protrusion 68 is fixedly installed on the surface of the fixed platform 62, and the convex disc 67 rotates to contact and collide with the surface of the protrusion 68 and generates vibration, and at this time, the convex disc 67 generates vibration under the action of the protrusion 68 and transmits the vibration to the cleaning cylinder 66.

[0045] The reciprocating screw rod 63 is slidably connected to the linkage plate 61, the reciprocating screw rod 63 and the linkage plate 61 are connected by threads, and the linkage plate 61 and the reciprocating screw rod 63 are connected by threads. At the same time, the movement of the linkage plate 61 drives the reciprocating screw rod 63 to rotate.

[0046] The end of the telescopic arc block 65 away from the fixed ring 64 is set as arc surface 2, and the circumferential surface of the cleaning tube 66 is provided with a brush plate. The movement of the telescopic arc block 65 drives the cleaning tube 66 to move and fit the surface of the cylinder sleeve. At this time, the cleaning tube 66 rotates under the action of the cylinder sleeve and drives the brush plate to rotate.

[0047] The circumferential surface of the reciprocating screw 63 is provided with a regularizing device for processing burrs and irregular protrusions on the surface of the cylinder liner, and the regularizing device includes a turntable 71, which is fixedly installed on the circumferential surface of the reciprocating screw 63, and a fixed table 2 72 is fixedly installed on the surface of the bottom plate 3. The surface of the fixed table 2 72 is rotatably penetrated by the reciprocating screw 2 73, and an inner turntable 74 is fixedly installed on the circumferential surface of the reciprocating screw 2 73. A burr removal rod 75 is slidably installed on the circumferential surface of the reciprocating screw 2 73, and an angle rod 76 is fixedly penetrated on the surface of the burr removal rod 75. One end of the angle rod 76 close to the turntable 71 is sleeved with a limiting cylinder 77, and a limiting rod 78 is fixedly installed on the surface of the sliding ring 52. The movement of the sliding ring 52 drives the limiting rod 78 to move in the direction close to the angle rod 76, and then the limiting rod 78 moves close to and contacts the inner wall of the angle rod 76 until it fits with the inner wall.

[0048] The burr removing rod 75 is connected to the reciprocating screw rod 73 by a threaded connection. The end of the burr removing rod 75 away from the reciprocating screw rod 73 is set as a cutter head. The shape of the burr removing rod 75 is set to an arc. The surface of the limiting cylinder 77 is provided with a hexagonal slot. The end of the limiting rod 78 close to the limiting cylinder 77 is set to a hexagonal shape. The turntable 71 is in contact with the fixed table 72, and the rotation of the turntable 71 drives the fixed table 72 to rotate.

[0049] When the present embodiment is working: when the output end of the motor 41 moves, the linkage plate 61 moves. Since the linkage plate 61 is connected to the reciprocating screw rod 63 by a threaded connection, the linkage plate 61 moves and drives the reciprocating screw rod 63 to rotate. The rotation of the reciprocating screw rod 63 drives the fixing ring 64 to rotate. The rotation of the fixing ring 64 drives the telescopic arc block 65 to rotate. At the same time, the telescopic arc block 65 rotates to contact the surface of the cylinder sleeve. Under the action of the cylinder sleeve, the telescopic arc block 65 moves toward the direction close to the center of the reciprocating screw rod 63 to adapt to cylinder sleeves with different diameters. At the same time, the telescopic arc block 65 moves and drives the cleaning cylinder 66 to move and fit the surface of the cylinder sleeve. At this time, the cleaning cylinder 66 rotates under the action of the cylinder sleeve and drives the brush plate to rotate. At the same time, the brush plate rotates to clean the surface of the cylinder liner, quickly removes rust, oil or residual grinding chips on the surface of the cylinder liner, and improves the processing effect of the grinder 2 on the cylinder liner. When the reciprocating screw 63 rotates to drive the cam 67 to rotate, the cam 67 rotates to contact and collide with the surface of the bump 68 and generate vibration. At this time, the cam 67 generates vibration under the action of the bump 68 and transmits the vibration to the cleaning tube 66. At this time, the cleaning tube 66 vibrates to achieve self-cleaning, avoiding metal chips and abrasive particles in the gap of the cleaning tube 66, avoiding the cleaning tube 66 from being affected by the attachment of impurities and thus affecting its own normal operation, and even affecting the cleaning effect of the cleaning tube 66 on the cylinder liner, so that the cleaning tube 66 can be kept in a relatively good state and the replacement frequency can be reduced.

[0050] When the reciprocating screw rod 1 63 rotates under the action of the linkage plate 61, the turntable 71 is driven to rotate. Because the turntable 71 is in contact with the fixed platform 2 72, the rotation of the turntable 71 drives the fixed platform 2 72 to rotate. Previously, the staff adjusted the angle of the burr removal rod 75 by rotating the angle rod 76 to make the blade head of the burr removal rod 75 fit the surface of the cylinder sleeve. Because the burr removal rod 75 and the reciprocating screw rod 2 73 are connected by threads, the rotation of the reciprocating screw rod 2 73 drives the burr removal rod 75 to move. The burr removal rod 75 reciprocates under the action of the reciprocating screw rod 2 73 to remove the burrs on the surface of the cylinder sleeve, ensuring the consistency and accuracy of the surface during the processing of the cylinder sleeve. If the burrs are not removed, the surface may be rough, affecting the matching accuracy and sealing of the parts, which is helpful Friction is reduced, damage is reduced, and the service life of the cylinder liner is extended. At the same time, the movement of the sliding ring 52 drives the limit rod 78 to move toward the direction close to the angle rod 76, and then the limit rod 78 moves close to and contacts the inner wall of the angle rod 76 until it fits with the inner wall. At this time, the burr removal rod 75 is limited and fixed while the cylinder liner is fixed, avoiding the burr removal rod 75 from shaking or vibrating during the subsequent cylinder liner surface treatment, thereby affecting the treatment of the cylinder liner, ensuring the stability of the deburring process, avoiding accidental movement or position change of the parts during the processing, reducing the risk of secondary damage, ensuring the consistency of surface treatment, making the surface of the cylinder liner smoother, helping to reduce oil retention and friction resistance, and improving component performance.
