DETAILED DESCRIPTION

[0017] In order to enable those skilled in the art to better understand the technical solution of the utility model, the technical solution of the utility model is further described below in conjunction with the accompanying drawings and embodiments. Example

[0018] like Figure 1-Figure 4As shown, an engine cylinder shaft cover grasping mechanism includes a shaft cover 1, a through hole 11 is arranged on the upper end surface of the shaft cover 1, a guide sleeve 2, a telescopic device and a driving component, the telescopic device includes a pull rod 3, the driving component is an external cylinder 4, the guide sleeve is divided into a guide sleeve head 21, a guide sleeve middle part 22 and a guide sleeve tail 23, the size of the guide sleeve head 21 matches the size of the through hole 11, the guide sleeve head 21 is connected in the through hole 11, three marble holes 24 are arranged in the guide sleeve head 21, marbles are installed in the three marble holes 24, the guide sleeve tail 23 is detachably mounted on the first mounting plate 5, a telescopic hole 25 is arranged inside the guide sleeve 2, the pull rod 6 is divided into a pull rod head 61, a pull rod middle part 62 and a pull rod tail 63, the pull rod tail 63 is connected to the external cylinder 4, the external cylinder 4 is mounted on the second mounting plate 7, and the first mounting plate 5 and the second mounting plate 7 are both mounted on the grasping mechanism body. The pull rod head 61 and the pull rod middle part 62 are both connected to the telescopic hole 25. The external cylinder 4 drives the pull rod 3 to move up and down in the telescopic hole 25. The pull rod head 61 is divided into a large part 611 and a small part 612. The outer diameter of the large part 611 is the same as the outer diameter of the pull rod middle part 62. The outer diameter of the pull rod middle part 62 matches the inner diameter of the telescopic hole 25. The outer diameter of the small part 612 is smaller than the outer diameter of the large part 611. A 30° gap is formed between the large part 611 and the small part 612. The length of the pull rod head 61 is greater than the distance from the marble to the telescopic hole 25. A first flat-bottomed groove 8 is provided on the outer wall of the guide sleeve 2, and a threaded hole 9 is provided on the first flat-bottomed groove 8. A second flat-bottomed groove 10 is provided in the middle part 62 of the pull rod. When the middle part 62 of the pull rod is located in the middle part 22 of the guide sleeve, the position of the second flat-bottomed groove 10 corresponds to the position of the first flat-bottomed groove 8. The bolt passes through the threaded hole 9 and supports the second flat-bottomed groove 10 to limit the movement of the pull rod 6.

[0019] When it is necessary to grasp the shaft cover 1, the guide sleeve head 21 is inserted into the through hole 11, the pull rod head 61 and the pull rod middle part 62 are inserted into the telescopic hole 25, and the output shaft of the external cylinder 4 drives the pull rod 6 to move upward in the telescopic hole 25 through the pull rod tail 63. During the movement, since there is a 30° conical angle between the small part 612 and the large part 611, and the outer diameter of the large part 611 is the same as the outer diameter of the pull rod middle part 62, the large part 611 can squeeze the marble outward during the upward movement, so that the marble and the inner wall of the through hole 11 of the shaft cover are in close contact, thereby playing a grasping role. At this time, the external cylinder 4 stops working. In order to better fix the pull rod The middle part 62, screws the bolt into the threaded hole 9, and the bolt passes through the threaded hole 9 to support the second flat-bottomed groove 10 of the middle part 62 of the pull rod, thereby further limiting the movement of the pull rod 6 in the telescopic hole 25, and can move the shaft cover to the required position. When it needs to be reset, the output shaft of the external cylinder 4 drives the pull rod 6 to move downward in the telescopic hole 25 through the pull rod tail 63, and the large part 611 moves downward. At this time, the position of the small part 612 corresponds to the position of the marble. In the absence of extrusion force and gravity, the marble returns to its position to achieve loosening, and the main body of the grasping mechanism moves up, so that the guide sleeve head 21 is separated from the shaft cover through-hole 11, and the next shaft cover 1 is clamped.
