Compression spring selection guide 1.Outside diameter or inside diameter choice：Select the outside diameter and inside diameter according to the size of the guide pin or countersunk hole，It is generally recommended that the rod diameter be smaller than the selected inside diameter 1.0mm around，It is recommended that the countersink bore be larger than the selected outside diameter 1.5mm around。Tolerance selection：Select according to actual use requirements:Outer diameter reference type（Negative tolerance），Internal diameter reference type（Positive tolerance），Spring constant tolerance±10%。2. Material selection：1).304 Stainless steel has strong corrosion resistance，Uniform toughness fatigue is better；2).The tensile strength of the piano wire is high、Good toughness，
The main parts of the electric cylinder1. The lead screw electric cylinder is usually used in the following forms：Trapezoidal screw、Ball screw、Advantages and disadvantages of different lead screw cylinders such as planetary roller lead screw:（1）Trapezoidal screw advantage：Easy to manufacture、Low cost、Large carrying capacity、It has certain self-locking characteristics shortcoming：The transmission friction is slightly higher、The transmission efficiency is slightly lower（2）Advantages of ball screw：High positioning accuracy、High transmission efficiency、Disadvantages of long service life
The difference between ball screw and trapezoid screw 1、Different trapezoidal screw structure because there is no ball，So the structure is relatively simple，More convenient installation and disassembly，But the accuracy is not as good as the ball screw。Ball screw belongs to rolling friction，The trapezoidal lead screw belongs to sliding friction。2、Transmission efficiency The transmission efficiency of different ball screws is trapezoidal2-4times，So generally speaking，Use the same lead，To drive the same load，Ball screws have an advantage。3、Self-locking Different ball screws do not have self-locking，The trapezoidal lead screw has the advantage of self-locking。But we also need to consider precision、Speed and other factors。4、manufacture

Product characteristics of different modules 1. Semi-enclosed lead screw module Product characteristics：1.Simple structure，Easy installation and maintenance，Lower cost，Widely used。2.Strong carrying capacity，100The body width and above adopt the double track structure，High rigidity。3.Flexible structure，A variety of desired structures can be customized、dimension。2.Fully enclosed screw module product features：1.Fully enclosed sealing design，Clean workshop or dust environment can pass positive and negative air pressure，Meet the needs of different environments，Relatively high cost。2.The bearing capacity is close to that of the semi-enclosed lead screw module。3.Our company has a good structure for many years
UseUVWCounterpoint platform advantage 1.The structure type is optional：Solid and hollow design can be realized2.Thin optimization：Stacking the old clunky motors，Improved coplanar design of cost axis，Greatly reduce the overall volume，And carefully designed，Make the counterpoint platform more stable and accurate3.stability：All aspects of alignment platform assembly，Inclusion screw、motor、Careful testing and improvement of rail and workpiece handling，Increase platform stability Accuracy and service life4.High rigidity：Selection of high-strength aluminum alloy and high-precision guide rail，Smooth table running5.High precision：Accumulated over the years
Types of couplings Bellows type coupling has strong flexibility,The absorption eccentricity Angle is remarkable,Even if there are errors, it can rotate at a constant speed.Suitable for encoders。 Cross ring type coupling allows radial,The angular deviation is large,Suitable for general purpose motors,Easy to disassemble and assemble。 Rigid coupling has strong rigidity,economical,shortcoming:The concentricity of the two axes is required to be high。 Grooved coupling integrated forming structure，Suitable for applications requiring high rotation accuracy。 Diaphragm type coupling torque rigidity is high,Stainless steel diaphragm can compensate radial,angular,Axial deviation。&nbs
A sprocket is a wheel with toothed buckle teeth，Used to engage a block with accurate pitch on a link or cable。Sprockets are widely used in chemical industry、Textile machinery、escalator，Wood processing，Three-dimensional parking garage，Agricultural machinery，Food processing、instrument、Mechanical transmission in petroleum and other industries。 Cause of excessive wear of sprocket： （1）The greater the adhesive wear load，The higher the surface temperature，The greater the adhesion。For certain hardness of metal materials，The relationship curves of wear rate and pressure were obtained by wear tests under different pressures，When the pressure reaches the hardness of the material1/3above
The lead screw module has a fast single motion speed、High repeated positioning accuracy、Light body weight、Occupies small device space、Long life and other characteristics。And high torsional rigidity，Can accurately control the rotation of the shaft，High precision control is possible。Friction junction is used for transmission，No gap，Ideal for ultra-precision control。Stainless steel diaphragm can compensate radial，angular、Axial deviation。Clockwise and counterclockwise rotation characteristics are exactly the same。Fixed by clamping。 The screw module was first developed and used in Germany，The market is positioned in photovoltaic equipment，Loading and unloading manipulator、Cutting equipment、Gluing equipment、Patch equipment, etc。There are several names for the lead screw module
Pneumatic grippers use compressed air as power，An executive device used to grab or grasp a workpiece。Originally originated in Japan，After being widely used by domestic automation enterprises。Usually can be divided according to the styleYType and type clamps，Bore division16mm，20mm，25mm，32mmand40MMSeveral kinds of，Its main function is to replace peoples grasping work，It can effectively improve production efficiency and work safety。SMCThe pneumatic finger series is one of the most commonly used pneumatic claw devices in the industrial field。 Type of pneumatic clamp： one、Parallel jaw Parallel jaw
