[0021] Combine Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, a carrying plate 11 is provided on the top of the frame 1, and a limited support plate 12 is provided above the carrying plate 11. A threaded rod 13 is rotatably installed at the bottom of the limited support plate 12. One end of the threaded rod 13 away from the limited support plate 12 is threadedly installed inside the carrying plate 11 and extends below it. In addition, a number of positioning rods 14 are evenly provided on the top of the carrying plate 11. The positioning rods 14 pass through the limiting support plate 12 and extend above it, and the end of the positioning rod 14 located above the limiting support plate 12 is provided with a supporting seat 141 for lifting the engine cylinder liner. The limiting support plate 12 can slide in the positioning position by rotating the threaded rod 13. The outer wall of the rod 14 is located below the material support seat 141, and the outer wall of the positioning rod 14 between the material support seat 141 and the limiting support plate 12 is surrounded by four circumferentially distributed arc-shaped limiting plates 15, and the outer wall of the positioning rod 14 between the material support seat 141 and the limiting support plate 12 is slidably installed with two positioning rings 16, and the outer walls of the two positioning rings 16 are rotatably installed at the positions corresponding to the arc-shaped limiting plates 15, and the other end of the connecting rod 161 is rotatably installed on the inner side of the arc-shaped limiting plate 15, and the outer wall of the positioning rod 14 is located between the two positioning rings 16 and a spring 17 is provided.

[0022] In one embodiment, when the engine cylinder liner is installed on the material rack, the engine cylinder liner can be snapped onto the positioning rod 14 in turn, so that the engine cylinder liner is sleeved on the outside of the arc-shaped limiting plate 15, and the engine cylinder liner is supported by the supporting seat 141 installed on the top of the positioning rod 14, and then the threaded rod 13 at the bottom of the limiting support plate 12 is twisted to allow the threaded rod 13 to extend above the supporting plate 11 inside the thread groove 111, and push the limiting support plate 12 to move upward, so that the limiting support plate 12 slides upward on the outer wall of the positioning rod 14 through the through hole 121, and then the sliding limiting support plate 12 pushes the positioning ring 16 located below to slide upward on the outer wall of the positioning rod 14 By moving, adjusting the distance between the two positioning rings 16, the two positioning rings 16 can push the four arc-shaped limit plates 15 to move in all directions by rotating the connecting rod 161 installed thereon, so that the four arc-shaped limit plates 15 are tightly attached to the inner wall of the inner hole of the engine cylinder liner to support it, and the installation and limiting of the engine cylinder liner can be completed. The engine cylinder liner can be installed on each positioning rod 14 in turn, and the engine cylinder liner on each positioning rod 14 can be limited at the same time to prevent the engine cylinder liner from shaking on the positioning rod 14, thereby avoiding the trouble of using a clamp to limit each engine cylinder liner in turn, saving time and effort, and improving the installation efficiency of the engine cylinder liner.

[0023] In one embodiment, since the material of the support seat 141 is rubber, when the engine cylinder liner is clamped on the top of the positioning rod 14, the rubber support seat 141 can contact the inner wall of the inner hole of the engine cylinder liner, preventing the positioning rod 14 from directly contacting the inner wall of the inner hole of the engine cylinder liner to generate friction, avoiding the situation where the positioning rod 14 is directly contacted with the inner wall of the inner hole of the engine cylinder liner to generate friction and scratching it, thereby ensuring the quality of the engine cylinder liner and protecting the engine cylinder liner.

[0024] In one embodiment, when limiting the engine cylinder liner on the positioning rod 14, the supporting seat 141 can first limit the positioning ring 16 located above, and then the limiting supporting plate 12 can push the positioning ring 16 located below to move, and adjust the distance between the two positioning rings 16. The two positioning rings 16 can push the four arc-shaped limiting plates 15 to move around by rotating the connecting rod 161 installed thereon, so that the four arc-shaped limiting plates 15 are tightly attached to the inner wall of the inner hole of the engine cylinder liner to support it. The position of the arc-shaped limiting plate 15 can be adjusted according to the diameter of the inner hole of the engine cylinder liner, and it can be supported and limited from the inner wall of the inner hole of the engine cylinder liner. It is suitable for limiting engine cylinder liners of different models and diameters, and is highly practical.

[0025] In one embodiment, since the internal thread of the limit nut 131 is in opposite direction to the internal thread of the thread groove 111, when limiting the limit support plate 12 after the adjustment position, the limit nut 131 on the outer wall of the threaded rod 13 can be screwed to make the limit nut 131 close to the lower end surface of the supporting plate 11, and the limit nut 131 can be tightened to the threaded rod 13 to prevent the threaded rod 13 from rotating, thereby avoiding the situation where the limit support plate 12 is displaced due to the rotation of the threaded rod 13, making it unable to limit the position of the positioning ring 16, thereby ensuring the stability of the limit support plate 12 after the adjustment position.

[0026] In one embodiment, when adjusting the position of the positioning ring 16, the positioning ring 16 can be limited by the limiting slider 162, so that the positioning ring 16 can slide on the outer wall of the positioning rod 14 through the cooperation of the limiting slider 162 and the limiting groove 142, preventing the positioning ring 16 from rotating on the outer wall of the positioning rod 14, avoiding the situation where the positioning ring 16 rotates on the outer wall of the positioning rod 14 and causing it to drive the arc-shaped limiting plate 15 and the engine cylinder liner mounted on the outside of the arc-shaped limiting plate 15 to rotate, thereby ensuring the stability of the engine cylinder liner.

[0027] In one embodiment, when the position of the positioning ring 16 is adjusted to push the arc-shaped limit plate 15 to move, the spring 17 between the two positioning rings 16 can support and limit it, preventing the two positioning rings 16 from sliding on the outer wall of the positioning rod 14 after the position is adjusted. This avoids the situation where the two positioning rings 16 slide on the outer wall of the positioning rod 14 after the position is adjusted, causing the connecting rod 161 and the arc-shaped limit plate 15 to move and be unable to support the engine cylinder liner, thereby improving the limiting effect of the engine cylinder liner.

[0028] The working principle of the present invention is as follows: when the engine cylinder liner is installed on the material rack for transportation, the engine cylinder liner can be engaged with the positioning rod 14 in turn, so that the engine cylinder liner is sleeved on the outside of the arc-shaped limiting plate 15, and the engine cylinder liner is supported by the supporting seat 141 installed on the top of the positioning rod 14, and then the threaded rod 13 at the bottom of the limiting support plate 12 is twisted, so that the threaded rod 13 extends above the carrying plate 11 inside the thread groove 111, and pushes the limiting support plate 12 to move upward, so that the limiting support plate 12 slides upward on the outer wall of the positioning rod 14 through the through hole 121, and then the sliding limiting support plate 12 pushes the positioning ring 16 located below to slide upward on the outer wall of the positioning rod 14, and adjusts the distance between the two positioning rings 16, so that the two positioning rings 16 are installed thereon by rotating The connecting rod 161 pushes the four arc-shaped limit plates 15 to move in all directions, so that the four arc-shaped limit plates 15 are tightly attached to the inner wall of the inner hole of the engine cylinder liner to support it, thereby completing the installation and limitation of the engine cylinder liner, and the engine cylinder liner can be installed on each positioning rod 14 in turn, and at the same time, the engine cylinder liner on each positioning rod 14 is limited to prevent the engine cylinder liner from shaking on the positioning rod 14, avoiding the trouble of using a clamp to limit each engine cylinder liner in turn, saving time and effort, and improving the installation and efficiency of the engine cylinder liner. Moreover, the position of the arc-shaped limit plate 15 can be adjusted according to the diameter of the inner hole of the engine cylinder liner, and it can be supported and limited from the inner wall of the inner hole of the engine cylinder liner. It is suitable for limiting engine cylinder liners of different models and diameters, and is highly practical.
