[0002] In the manufacturing industry, especially in the field of engine manufacturing, the cylinder liner is an important part of the engine. Traditionally, the cylinder head is directly put into the casting machine for casting. During the casting process, a reliable device is needed to grab the cylinder liner, put it into the casting machine for casting, and then take out the cast cylinder liner. Usually, these operations need to be completed manually or by a robotic arm, but manual operation is inefficient. If a traditional robot is used, two robots need to be configured, one for grabbing the cylinder liner and the other for grabbing the cylinder head, which is costly and occupies a large area.

[0022] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1-3 As shown, the embodiment of the utility model provides a cylinder sleeve and cylinder head grasping device, including:

[0024] The inner support assembly includes a first chuck 1 and a second chuck 2, the tails of the first chuck 1 and the second chuck 2 are fixedly connected, the second chuck 2 has a floating leveling assembly outside, the floating leveling assembly includes a floating ring 3, the inner wall of the floating ring 3 is outside the claws of the second chuck 2, when the cylinder sleeve is grabbed, the floating ring 3 abuts against the top wall of the cylinder sleeve;

[0025] A connecting positioning plate 4, the inner support assembly is connected to the connecting positioning plate 4, the connecting positioning plate 4 has a connecting area 14 fixedly connected to the six-axis robot 5, and a fixing block 7 for fixing the wiring harness or air pipe 13 is also fixed below the connecting positioning plate 4.

[0026] The utility model is used in the following process: the grabbing assembly is installed on the six-axis robot 5 through the connection area 14. When the cylinder sleeve needs to be grabbed, the six-axis robot 5 drives it to move to the top of the cylinder sleeve. Then, the claws on the second chuck 2 move outward to form an inner support in the cylinder sleeve to grab the cylinder sleeve. When grabbing, the floating ring 3 abuts against the cylinder sleeve, and then waits until it is moved to the cavity of the mold of the casting machine 6 after the mold is opened. When it moves into place, the claws of the second chuck 2 shrink to put down the cylinder sleeve. At this time, the cylinder sleeve may be in contact with the cavity. There is a gap at the bottom. Under the action of the floating ring 3, the cylinder sleeve is pushed to the bottom of the cavity so that it fits the bottom of the cavity. Finally, the grasping device withdraws. After waiting for the casting to be completed, the six-axis robot 5 flips 180 degrees and switches to the first chuck 1. The first chuck 1 enters the cavity after the mold of the casting machine 6 is opened again to grasp the formed cylinder sleeve (the cylinder head is formed after the cylinder sleeve is formed, and the cylinder head is formed by casting a cylinder head body outside the cylinder sleeve). At this time, the claws of the first chuck 1 move outward again, and form an internal support with the cylinder sleeve of the cylinder head again, so it can be taken out.

[0027] Furthermore, the first chuck 1 and the second chuck 2 are both three-jaw chucks. Such a design enables the gripping device to have stronger gripping force and stability, and can better adapt to cylinder liners of different shapes and sizes. Of course, a four-jaw chuck can also be used, but the price and maintenance cost are slightly higher.

[0028] Furthermore, there are two fixing blocks 7 connected to the bottom of the positioning plate 4, and the fixing blocks 7 include a lower fixing portion 8 and an upper fixing portion 9, and the lower fixing portion 8 is connected to the upper fixing portion 9 by screws. By setting two fixing blocks 7 connected to the bottom of the positioning plate 4 and connecting the lower fixing portion 8 and the upper fixing portion 9 by screws, the stability and reliability of the fixing blocks 7 are enhanced, so that the air pipe 13 or the wiring harness therein will not shake.

[0029] Furthermore, the outer wall of the clamping claw is in an arc shape matching the cylinder sleeve. Such a design can better contact the cylinder sleeve, reduce damage to the cylinder sleeve, and improve the grasping accuracy and safety of the grasping device.

[0030] Furthermore, the length of the claws of the first chuck 1 is two-thirds of the length of the claws of the second chuck 2. Because the floating ring 3 needs to be installed on the second chuck 2, the claws of the second chuck 2 need to be set longer so that the claws can firmly grasp the cylinder sleeve.

[0031] Furthermore, the floating leveling assembly includes a plurality of connecting plates 10 fixed on the second chuck 2, a connecting rod is movably connected to the connecting plate 10, a limit head 11 is provided on the top of the connecting rod, the floating ring 3 is fixedly connected to the end of the connecting rod, and a floating spring is provided outside the connecting rod. Through this structure, after the cylinder sleeve enters the mold cavity of the casting machine 6, it can play a pushing role and push it to the bottom of the mold cavity, thereby ensuring the quality of the casting.

[0032] Furthermore, the first chuck 1 and the second chuck 2 are both pneumatic chucks, and the fixed block is provided with an air pipe 13. By using pneumatic chucks as the first chuck 1 and the second chuck 2, and fixing the air pipe 13 on the fixed block, the grasping device can more flexibly control the movement of the claws, thereby improving the grasping accuracy and stability. Of course, the pneumatic chuck can also be an electric chuck.

[0033] Furthermore, the center lines of the first chuck 1 and the second chuck 2 are on the same axis. With this arrangement, the connection between the first chuck 1 and the second chuck 2 is simpler, for example, chucks of the same size can be used, and the tails of the chucks are fixedly connected by connecting protrusions and screws. At the same time, the robot only needs to flip 180 degrees to interchange the positions of the two chucks, and its moving path is also simpler.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
