What is the difference between linear motion and hard box guideways, and how CNC to choose right guideways?

The guide rail on the machine tool is divided into two kinds: linear rail and hard rail, the accuracy of the linear rail is higher than that of the hard guideway, but the hard rail is more durable and durable.

1. Linear guideway

It is our common linear guide rail, the linear guide rail itself is divided into two parts: the slide rail and the slider, the slider has an internal circulation of balls or rollers, and the length of the slide rail can be customized. It is a modular component, a standardized series of individual products produced by specialized manufacturers, which can be installed on the machine tool and disassembled and replaced after wear. The linear rail is rolling friction, which is fast, has low resistance, and is also convenient for lubrication.

The internal structure and principle of the pilot-operated check valve, Air cut-off protection to prevent the cylinder from falling

The principle of the pilot operated check valve is similar to that of the pressure holding valve, the exhaust port also needs to be vented before it can be opened, and if the air is cut off, the exhaust port will automatically close to prevent the cylinder from falling.

Why add balance cylinder to J2 axis of robot? 99% of mechanical engineers choose to ignore it.

Just studied Japanese and German robots in the workshop, and found that slightly larger robots, J2 will be equipped with a balance cylinder, Japanese FANUC robot uses spring type balancing, German KUKA uses hydraulic type (diaphragm accumulator) or counterweight block method, I personally think that hydraulic (diaphragm accumulator) way is the best, the output is basically constant, and it occupies little space.

Spinning machine robot loading and unloading automation unit design

1 Project overview

1.1 Customer requirements

Use industrial robot to complete the automatic loading and unloading of spinning machine.

1.2 Actual situation

The raw material is disc-shaped, the workpiece is a circumferentially symmetrical rotary body, diameter: φ215mm Height: 7.3mm Weight: about 2kg. 

Part name: Reducer shell

Using spinning machine, the disc material is spin-formed into the reducer shell.

Spinning machine robot loading and unloading automation unit design

1.3 Note

In order to ensure the feasibility of the solution and the continuous and stable production of the automation cell, your company should meet:

  1. System workflowThe spinning machine should have an I/O signal output function, which can be automatically controlled by transformation. The spinning machine top plate action can be controlled by an external signal, and the ejection speed and position can be adjusted. In order to ensure the stability of production, the equipment provided by customer should be able to operate stably, otherwise any problems caused by this will be solved by customer.
  2. The blank is manually brushed and placed on a conveyor line, which transports it to the end V-shaped positioning, and then the jacking cylinder lifts it up. claw is suitable for workpieces within a specific size (robot grasping position size), if the workpiece size difference is large, you can do a series of claws or replace finger blocks and fingers.

2 Solution

The automatic loading and unloading project of spinning machine is composed of one spinning machine (on-site modification), one FANUC M-710iC/45M robot (including claw and base), one loading conveyor line, one unloading conveyor line, safety gate, safety fence and electrical control system integration. In order to meet the requirements of robot feeding, the spinning machine equipment must be mechanically and electrically modified, and the main transformation tasks involve manipulators, electricity, gas, oil circuits, etc. The following describes the systems and major devices referenced in this solution.

principle of the hydraulic shank clamping tool, relying on the deformation of the shell caused by hydraulic oil to achieve clamping loosening

The principle of hydraulic tool holder is to use two concentric cylinders of inflatable shafts, seal the two ends to form a cylindrical cavity, fill one of the cylinders with hydraulic oil, and apply a certain pressure to the oil, and this pressure will be transmitted to each part of the oil cavity with equal values. The outer wall of these two concentric cylinders is thin, and after pressure, it will expand outward, according to this deformed thin wall, the expansion clamping of the inner hole and the expansion clamping of the outer diameter can be realized. At this time, the thin wall is actually evenly subjected to oil pressure in every place, so after the inner hole and outer diameter of the part are tightened, its clamping accuracy will be very high, and the hydraulic tool holder is developed according to this principle and successfully applied to the CNC machining manufacturing industry.

Is the robot high technology? The technology may not be as high as the excavator

When you mention industrial robots, you will think of intelligent manufacturing, which always gives people a feeling of being high technology, but do robots really belong to high-end manufacturing?

I was shocked to see a map of the excavator's operating range, which was almost exactly the same as the 6-axis robot's range of action.

Robot could not walk in a straight line, in addition to positioning accuracy, there is also repeatability of the path

Robots are not omnipotent, the more projects you do, the more you feel the limitations of the robot, not as powerful as we think, robots are generally used in occasions where the accuracy is not high, such as handling, welding, painting, etc., and for cutting, assembly, etc. is not enough, the root cause of this problem is that the accuracy of the robot repeat path is too low, far less than the manipulator or linear module.

Before we engaged in a cutting project, the cutting tool was fixed at the end of the robot, and the robot was used to complete the cutting, but when the actual execution was performed, it was found that the trajectory of the robot cutting was crooked, not a very straight line at all, and the expected effect was too different.
