DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model embodiment discloses a camshaft installation tool, which is mainly composed of the following parts: 2 back plates 1, 2 side plates 2, 2 H-shaped steels 3, 1 positioning bracket 4, 1 first steel plate 5, 2 second steel plates 6, 1 third steel plate 7, 2 handles 9, 2 brackets 13, 2 channel steels 14, and 2 guide rails 15.

[0024] Specifically, it includes two H-shaped steels 3 arranged horizontally in parallel, a third steel plate 7 arranged horizontally at the bottom of the ends of the two H-shaped steels 3, a positioning bracket 4 arranged vertically on the ends of the two H-shaped steels 3 away from the third steel plate 7, brackets 13 located vertically on both sides of the positioning bracket 4 and respectively arranged on the sides of the two H-shaped steels 3 away from each other, a channel steel 14 arranged horizontally on the two brackets 13, and a guide rail 15 arranged horizontally on the channel steel 14.

[0025] The bracket 13 is provided with a groove for placing the channel steel 14. There are two channel steels 14 on the bracket 13 and they are parallel to each other. The length direction of the channel steel 14 is perpendicular to the length direction of the H-shaped steel 3. Vertically arranged side plates 2 are provided on both sides of the end of the H-shaped steel 3 where the third steel plate 7 is located. The two side plates 2 are respectively located on the sides of the H-shaped steel 3 away from each other and extend upward. A first steel plate 5 is horizontally arranged between the tops of the two side plates 2, and a back plate 1 and a second steel plate 6 are vertically arranged, wherein one of the back plates 1 is located at the end of the first steel plate 5 away from the positioning bracket 4, and the second steel plate 6 is located at the end of the first steel plate 5 close to the positioning bracket 4; the two side plates 2 are provided with handles 9 on the sides away from each other.

[0026] The back plate 1, the side plate 2, the H-shaped steel 3, the first steel plate 5, the second steel plate 6, the third steel plate 7 and the bracket 13 are assembled together by welding.

[0027] The handle 9 is mounted on the side plate 2 by the first screw 8. The positioning bracket 4 is mounted on the H-shaped steel 3 by the cylindrical pin 10, the second screw 11, and the first nut 12. The channel steel 14 and the guide rail 15 are assembled together by the third screw 16 and the second nut 17, and can be directly placed on the groove on the bracket 13.

[0028] When installing the segmented camshaft, first install the bearing segments at both ends of the segmented camshaft. When installing the bearing segment, remove the positioning bracket 4 and place the bearing segment on the guide rail 15. Lift the installation tool through the lifting hole on the upper part of the installation tool, and move the bearing segment into the frame through the special shape of the installation tool. Adjust the position of the bearing segment through the handle 9 so that the bearing segment is aligned with the camshaft hole on the frame, and then push the bearing segment into the camshaft hole through the guide rail 15 to complete the installation of the bearing segment.
