Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, in particular to a separation fork pin press-fit fixture. Background Art

[0002] The release fork relies on the thrust of the release push rod to select the ball head support as the support point, pushing the long arm fork-shaped stamping part between the release bearing and the pin shaft. The release fork is separated from the plug-in shaft, and either the plug-in shaft comes out, or the hinged bearing on the release fork moves to separate the torque transmitted by the engine from the drive shaft, thereby interrupting the torque transmission process and changing the connection method of the movable installation.

[0003] Existing problems:

[0004] 1. Separation fork and plug-in shaft assembly technology When separating the fork assembly, it relies on manual hammering. Because the space inside the shell is narrow, the hammer can only slowly knock the separation shaft assembly. The force of knocking the assembly is uneven, and some separation shafts are not installed in place and knocked out in the opposite direction, resulting in a long assembly time, affecting the assembly efficiency and becoming a bottleneck process;

[0005] 2. In addition to the assembly of the fork pin by extrusion, other accessories related to the separation fork also need to be assembled by extrusion. Some accessories require one side to be fixed and the other side to be moved, but there is a lack of suitable fixtures to use. Utility Model Content
