Detailed Description
As shown in fig. 3-7, the utility model discloses an automatic locking device of camshaft, including main body frame, slip table mechanism 3, locking mechanism 8, slip table mechanism 3 with main body frame installs together, locking mechanism 8 with slip table mechanism 3 links to each other, slip table mechanism 3 is used for the drive locking mechanism 8 carries out the lift removal, locking mechanism 8 includes locking drive module and locking clamping jaw 12, locking drive module is used for the drive locking clamping jaw 12 is closed.
The sliding table mechanism 3 drives the locking mechanism 8 to move up and down, and controls the locking mechanism 8 to enter (exit) a working position.
The main body framework comprises a base 1 and a stand column 2, wherein the stand column 2 is installed on the base 1, and a sliding table mechanism 3 is installed on the stand column 2.
The sliding table mechanism 3 comprises a sliding table support 4, a back plate 5, a first air cylinder 6 and a tank chain 7, wherein the sliding table support 4 is installed on the stand column 2 of the main body frame, the back plate 5 is installed together with the sliding table support 4, the first air cylinder 6 is installed together with the back plate 5, the first air cylinder 6 is used for driving the tank chain 7 to move, and the tank chain 7 is connected with the locking mechanism 8.
In the free state, the head of the locking clamping jaw 12 is in an open state under the elastic force of the clamping jaw return spring 11 of the locking clamping jaw 12. When the camshaft needs to be locked, the second air cylinder 9 drives the bolt 10 to be inserted into the tail part of the locking clamping jaw 12, and the head part of the locking clamping jaw 12 is closed to clamp the camshaft along with the pressing of the bolt 10.
The locking mechanism 8 further comprises an insert 13, the head of the locking clamping jaw 12 is provided with the insert 13, the insert 13 is made of a cutter material, and is resistant to compression and abrasion, so that the locking clamping jaw 12 is guaranteed not to be abraded after long-term operation.
When the engine enters the station, the jacking and pressing device fixes the posture of the engine. The first cylinder 6 drives the sliding table mechanism to descend, so that the locking clamping jaw 12 enters a working position (wraps the hexagonal part in the middle of the camshaft). At this time, the head of the locking clamping jaw 12 is in an open state under the elastic force of the clamping jaw return spring 11 of the locking clamping jaw 12. Then the second cylinder 9 drives the bolt 10 to insert into the tail of the locking clamping jaw 12, and the head of the locking clamping jaw 12 is closed to clamp the camshaft along with the pressing of the bolt 10. After the camshaft is clamped tightly, the staff finishes the screwing of the camshaft chain wheel, and in the screwing process, the locking clamping jaw 12 always presses the camshaft to prevent the camshaft from rotating along with the camshaft.
