[0030] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] like Figures 1 to 5 As shown;

[0032] A cylinder liner inner ring honing machine, comprising:

[0033] A waste chip separation device 1, a fixed seat 2, an oil pump 3 and a grinder 4; a feed box 5 is fixedly connected to one side of the grinder 4, a spindle 6 is provided in the middle of the feed box 5, a honing head 7 is provided on the spindle 6 close to the grinder 4, four honing bars 8 are evenly provided on the side of the honing head 7, a No. 1 nozzle 9 and a No. 2 nozzle 10 are respectively provided on both sides of the honing bar 8, a No. 1 nozzle 11 is provided on the No. 1 nozzle 9, the No. 1 nozzle 11 is arranged parallel to the honing bar 8, the No. 1 nozzle 11 is tilted downward, a No. 2 nozzle 12 is provided on the No. 2 nozzle 10, the No. 2 nozzle 12 is arranged at a certain angle to the honing bar 8, and the No. 1 nozzle 9 and the No. 2 nozzle 10 are connected to the oil pipe 13 of the oil pump 3 through a swivel joint 30 fixedly connected to the spindle 6;

[0034] The grinding machine 4 is provided with a rotating shaft 14, and a bracket 15 is fixedly connected to the rotating shaft 14. Both ends of the bracket 15 are respectively fixedly connected to fixed seats 2, and one of the fixed seats 2 is located directly below the honing head 7;

[0035] During use, the grinder 4 is generally provided with two workstations. The worker puts the cylinder liner into the fixed seat 2 of the workstation to be processed. The worker's body is too close to the honing head 7. In order to avoid the honing head 7 splashing waste chips during operation, which is easy to cause dangerous accidents, and because the body is tilted at a large angle, it is easy to cause bumps when taking and placing the cylinder liner due to unstable grip. Two fixed seats 2 are fixed at both ends of the bracket 15, one of which is just below the honing head 7, and the other is far away from the honing head 7, so that the worker can take and place the cylinder liner in the fixed seat 2 far away from the honing head 7, and then the bracket 15 is connected with the rotating shaft 14. The grinder 4 is rotatably connected to rotate the fixed seat 2 with the unprocessed cylinder liner to the bottom of the grinding head for honing. At the same time, the fixed seat 2 at the other end will rotate to the side away from the honing head 7. The workers can stay away from the honing head 7 when taking and placing the cylinder liner, so as to prevent the occurrence of dangerous accidents and ensure the safety of the workers. During processing, the spindle 6 drives the honing head 7 to rotate, and the feed box 5 will push the honing head 7 to move up and down.

When kerosene is sprayed onto the inner ring of the cylinder liner, the kerosene will generate a flushing flow force horizontally along the inner ring of the cylinder liner, so that the waste chips that are not quickly flushed out of the inner ring of the cylinder liner by the first nozzle (11) can be flushed toward the first nozzle (11), and then flushed out of the inner ring of the cylinder liner by the kerosene sprayed by the first nozzle (11). At the same time, the direction of the kerosene sprayed by the second nozzle (12) is the same as the rotation direction of the grinding head, so that the inner ring of the cylinder liner can be flushed before the honing bar is used for honing.
