Precise positioning ± 0.1mm!

🤔 Why does a chain stop hundreds of pounds of work boards on a whim?

Let's imagine a scenario: on an assembly line, a fixture plate carrying a refrigerator compressor rumbles forward, and then suddenly "clicks" and stops right in front of the worker, with a margin of error smaller than a hair's breadth! This is not magic.Blocking and stopping technology for doubled speed chainsIn bracing. Simply put, it's like putting precise reins on a wild horse running wild - stopping it firmly, but not strangling the horse in pain.

🛠️ Stopper Trio: Cylinder + Stop Block + Locating Pin

Want to make the high-speed movement of the work plate instantly stationary? It's up to these three brothers to play along:

1. ​Blocking cylinders: The pneumatic piston rod pops out with a swish and pushes against the front edge of the tooling plate. Here's the kicker!Piston rod tip with rollerThe board is "rolling friction", not hard contact. It's like rubbing a basketball with the palm of your hand, the ball stops and your hand doesn't hurt.
2. ​Anti-Rebound Stop: It temporarily lowers its head when the plate is pressed against it, and then springs up as soon as the plate passes over it. What if the plate tries to "reverse"? No way! It will directly block you back.
3. ​Locating pin sleeve: The ultimate positioning artefact! The cylinder jacks up the work plate instantly, theSteel locating pins "click" into the holes of the tooling plate.The error is locked to ±0.1mm. What is the concept of this precision? It is equivalent to precisely inserting a Coke can into the vending machine's pick-up slot.

📌case studies: A power plant to the refrigerator compressor assembly line on this system, the results of the assembly error rate from 5% plummeted to 0.1%! Workers are happy: "Previously on the hole to the eyes to the eyesight, and now close your eyes can be mounted accurately."

🔍 The Black Technology Behind Precise Positioning (It's Not Really That Complicated!)

​Q: Why do you have to use rolling friction? Can't you just brake to death?​
​replyThe most important thing is to avoid "hard braking" - the chain is still running! The chain is most afraid of "hard braking" - the chain is still running, and if the plate suddenly jams, the parts will fly away, or the chain will break. What is the beauty of rolling friction? Look at this comparison table to understand:

As an example: automotive plants usehydraulic vibration absorberThe blocking cylinder, the work plate hit the piston rod, the hydraulic oil "Zi" cushion kinetic energy, the impact is directly eaten away 90%.

🧩 Three top tips for accuracy ±0.1mm

Don't think you can just install a cylinder! These three details are the key:

1. ​dual insurance positioning::

   • First weight: blocking cylinder forced stop (coarse positioning)
   • Second weight: the jacking mechanism lifts the work plate off the chain.Locating pin inserted into locating hole(fine positioning)

   It's like parking in a garage - first roughly to the side (coarse positioning), then fine-tuning the reverse (fine positioning).

2. ​Sensor Gold Partner::

   • The photoelectric sensor spots the work plate 10cm in advance and signals the PLC, "Attention! A car is coming in!"
   • The encoder monitors the chain speed in real time and calculates the braking distance.

   An electronic factory car lessons: not installed sensors, the result of the work plate "bam" hit the crooked positioning pin, stop production for half a day.

3. ​Workplace boards compete on their own::
   Base plate must be withHigh precision positioning holesThe tolerance is ≤0.05mm, and the materials have to be tough - steel plates for heavy loads and carbon fibre for anti-static.

🚀 Upgraded play: adding "extras" to stop-start technology

Want to double your efficiency again? Try these tawdry manoeuvres:

• ​RFID chip implantationWorkpiece plate with its own "ID card", to the station to automatically retrieve the assembly parameters.
• ​Visual Deskew System: The camera scanned the position of the tooling plate and found it to be off by 0.2mm? Immediately had the cylinders fine-tuned!
• ​Duplex relay: When station A blocks and stops assembly, station B is ready for the next workpiece, and the capacity is directly x 2 (measured data from a computer motherboard factory).

💡personal viewpointDon't blindly chase the "fully automatic"! Many manufacturers of robotic arm positioning is not as accurate as the stop cylinder, it is better to build a solid foundation first.

⚠️ Pit Avoidance Guide: A Must for Beginners

1. ​Don't be stingy with cylinder selection::

   • For small loadsSpring loaded buffer cylinders(cheap enough)
   • Big loads must go onHydraulic vibration-absorbing cylinders! Otherwise change the piston rod once every three months.

2. ​Maintenance access is adequate::
   Duplex stop and go system as complex as Lego, no room for maintenance? The master has to tear down the walls when the equipment breaks down!

3. ​Periodic medical check-up of locating pins::
   A new energy plant has suffered a loss - positioning pin wear 0.3mm did not notice, the result of the battery module inserted crooked, burned the entire line.

🌟 And finally, something real.

Playing around with blocking and stopping techniques is essentially inBalancing "fast" and "accurate"The first is a virtual preview of the process. Now some factories have come up with virtual previews - using SolidWorks modelling to simulate the stopping process, even how tight the screws are turned can be calculated. If you ask me, the future must beData + Machineryof the world: the sensors you bury today may become codes for doubling capacity tomorrow!
