Representing linkage systems with kinematic diagrams
Step 1: Identify the frame. Step 2: Identify all other links. Step 3: Identify the joints. Step 4: Identify any points of interest. Step 5: Draw the kinematic diagram. Linkage examples
3
Draw a kinematic diagram.
This shear press is used to cut and trim electronic circuit board laminates. Draw a kinematic diagram.
4
Step 1: Identify the frame.
The large base that is bolted to the table can be considered the frame. 1 Step 1: Identify the frame.
5
Step 2: Identify all other links.
There are 3 moving links: Link 2: Handle Link 3: Cutting blade Link 4: Bar that connects the cutter with the handle 4 3 1 Step 2: Identify all other links.
6
Step 3: Identify the joints.
2 Pin joints connect: Link 1 to 2 (A) Link 2 to 3 (B) Link 3 to 4 (C) The sliding joint connects link 4 to 1. (D) B A 3 4 C D 1 Step 3: Identify the joints.
7
Step 4: Identify any points of interest.
The motion of the end of the handle is significant. We can mark this with X. X 2 B A 3 4 C D 1 Step 4: Identify any points of interest.

9
Draw a kinematic diagram.
Note the linkage in these locking pliers. Draw a kinematic diagram.
10
Step 1: identify the frame.
11
Step 1: identify the frame.
No links are grounded here, so the choice of frame is arbitrary. We could, for example, identify the top handle as the frame (1). 1 Step 1: identify the frame.
12
Step 2: identify all other links.
13
Step 2: identify all other links.
The remaining moving parts are the bottom handle (2), the bottom jaw (3), and the bar that connects the top and bottom handles (4). 1 4 3 2 Step 2: identify all other links.

Step 3: identify the joints.
1 4 3 2 Step 3: identify the joints.
15
Step 3: identify the joints.
The joints are labeled A-D. 1 D A 4 3 C B 2 Step 3: identify the joints.

Step 4: identify any points of interest.
1 D A 4 3 C B 2 Step 4: identify any points of interest.
17
Step 4: identify any points of interest.
The motion of the end of the bottom jaw (X) and the end of the bottom handle (Y) are of interest. 1 D A X 4 3 Y C B 2 Step 4: identify any points of interest.
