50 classic mechanical structure GIF appreciation, understand a lot of mechanical principles
summary：1. Drophammer Input: Green belt wheel shaft, green shaft and red hollow shaft there is a slide key. The yellow slider moves up and down depending on the green bar.
1. Drophammer
Input: Green belt axle
There is a slip key between the green shaft and the red hollow shaft.
The yellow slider moves up and down depending on the green bar.
2. Friction Press 1 (Frictionpress1)
Input: Green belt axle
There is a slip key between the green shaft and the red hollow shaft.
The blue disc - screws interchangeably contact the two red discs.
The up and down movement of the yellow slider is controlled by the purple rod.
The slider reaches the maximum speed at the lowest position of the stroke and the maximum speed at the highest position.
The pink stop determines the highest position of the slider.
Frictionpress2 (Frictionpress2) Input: Center pinionPurple disk carries four gears and two roller columns.
The roller alternately contacts the yellow disc and reciprocates the screw motion.
Enantiogenic blue nut - slider mechanism up, down, resident motion, the rod has three different positions.
There is a stop that keeps the disk stationary while it resides and is not displayed.
4. Manual punch 1 (Handpunchmachine1)
Combination of gear drive and slider-crank mechanism.
5. Manual punch 2 (Handpunchmachine2)
Disk CAM and linear reciprocating follower.
6. Manual shearingmachine1 (Handshearingmachine1)
A planetary gear was used.
Manual force is applied to the satellite gears.
Other gears fixed.
The tool stand above is fixed on the carrier.
7. Manual shearingMachine2 (Handshearingmachine2)uses a four-link mechanism.
Manual force is applied to a crank.
The tool bench above is fastened to the other cranks.
8. Footshearingmachine1 (Footshearingmachine1)
The blue slider is driven by a slider crank mechanism.
The crank is a purple pedal.
Orange low shear piece fixed to the mechanism base.
The red upper shear plate has an oblique edge to reduce the shear force.
9. Footshearingmachine2 (footshearingmachine 2)
The blue slider is driven by a six-bar mechanism.
The track of the green slider is on the blue slider.
Orange low shear piece fixed to the mechanism base.
The red upper shear plate has an oblique edge to reduce the shear force.
10 Tablewoodsaw1
Orange round blade position adjustment motion:
Use pink nuts for up and down movement. The motor is adjusted by pink pin.
Use orange nuts for inclined motion.
11. Tablewoodsaw2
Orange round blade position adjustment motion:
Use pink nuts for up and down movement. The motor and blade shaft are adjusted by pink pins.
Use pink nuts for inclined motion.
12. Flip Mechanism 1 (Flippingmechanism1)
This mechanism can flip over a flat plate with two 4-bar mechanisms.
The two flip boards are actually two 4-bar extensions of the fourth bar.
13. Flip Mechanism 2 (Flippingmechanism2)
Connecting rod Length: 50
Two crank lengths: 120 and 140
Distance between two fixed bearings: 50
Workpiece 180° Rotation corresponding to blue crank rotation 90° .
14. Transportmechanism1 (Transportmechanism1)
The egg-shaped motion of the blue joint is used to move the red workpiece.
is the locus of a point on the pink bar 4 bar mechanism.
The yellow and orange rods are connected to form a parallelogram mechanism.
