A slide hammer is a tool that attaches to an object needing to be pulled and transmits an impact force to the object without striking the object itself. Slide hammers typically consist of a long metal shaft with an attachment point at one end, a heavy weight that can slide along the shaft , and a stop for the weight to impact on the end ...
The Adell and Starrett mechanism uses a sliding block crosswise through the hammer rather than an intermediate pin. The hammer has a hole through its center that the top of the punch sits in, and holds the top of the punch centered. The sliding block has a hole through it that, when reset, is misaligned with the hole through the hammer.
Constant lead barrel cam in an American Pacemaker lathe. This cam is used to provide a repeatable cross slide setting when threading with a single-point tool. A cylindrical cam, or barrel cam, is a cam in which the follower rides on the surface of a cylinder. In the most common type, the follower rides in a groove cut into the surface of a ...
Specifically for internal broaching a hole must first exist in the workpiece so the broach can enter. [10] Also, there are limits on the size of internal cuts. Common internal holes can range from 0.125 to 6 in (3.2 to 152.4 mm) in diameter but it is possible to achieve a range of 0.05 to 13 in (1.3 to 330.2 mm).
The geometry of the way can vary depending on the situation. The most common types are flat, vee, and dovetail ways. Flat ways are used when there is little requirement for the slide to be constrained perpendicular to the axis of movement, or the constraint is being provided by another component or otherwise not needed, such as on the carriage of a lathe.
Balance shaft in Ford Taunus V4 engine.. Balance shafts are used in piston engines to reduce vibration by cancelling out unbalanced dynamic forces. The counter balance shafts have eccentric weights and rotate in opposite direction to each other, which generates a net vertical force.
