Description/Basics

centering pins are used to fix the position and limit the degrees of freedom of the objects to be positioned. The precisely manufactured centering pins enable highly precise positioning of the assembly parts. centering pins can position objects as side stopper or center them by insertion. This allows positioning them in the X, Y and Z axes.

 

 centering pint as workpiece stopper

Application example: centering pin as work piece stopper - (1) work piece, (2) threaded receiving pin

 

A straight centering pin is only sufficient for the X and Y axis to determine the position of an assembly part. In order to additionally adjust the position in the Z axis, a centering pin with a collar can be used. This combination can reduce the variety of components, since there is no need for an additional support pin.

 

Positioning pin with collar

Application example for a centering pin with collar

 

In most cases a plug-in connection uses a centering pin to protect the work piece or the application during multiple joining and positioning. The centering bushings protect the component from unwanted wear, especially if the objects to be placed are made of a soft material. Therefore, positioning bushings make an application more maintenance-friendly. Wear should always be considered when planning an application. The material and the surface coating of centering pins should be selected according to the application.

Function

If objects cannot be placed straight, but slightly inclined on centering pins, a round or chamfered head shape can be used. This helps ensure that the objects do not jam with the centering pins and the process runs smoothly. A round or chamfered head shape is also advisable for applications that are highly repetitive (cycles).

Application example for an inclined infeed - (1) centering pin rounded head, (2) workpiece

 

For the highest possible positioning accuracy centering pins should be used in pairs as much as possible. The respective distance between the centering pins also influences the position accuracy. If it is chosen large, it can improve the accuracy of the object’s positioning. If there is a large distance between the centering pins (B), one of the locating pins should have a diamond-shaped head (sword pin), since a sword pin almost prevents tilting. The use of a third centering pin in an L-shaped (triangular) arrangement may improve the positioning accuracy even further. In order to ensure that the centering pins are not interchanged, centering pins with different diameters should be selected.

MISUMI offers various mounting variants for centering pins in order to keep applications maintenance-friendly. Centering pins with internal threads can be interchangeably fastened with a screw through the mounting plate from underneath. If access to the underside is difficult, a centering pin or sword pin with external thread can be used. The assembly and disassembly of the centering pins can thus be easily designed by means of the various mounting versions.

Areas of Application

centering pins are used in work piece carriers as well as the highly accurate positioning of components in test benches. centering pins enable highly precise positioning of objects with all degrees of freedom, thanks to the versatile and highly configurable shapes. The wide variety of MISUMI centering pins offers a suitable shape for every application. Centering pins are used for thin sheets as well as for heavy and complex components. This means that centering pins can be used across almost all industries of plant engineering and mechanical engineering. In many applications, centering pins are indispensable, as they enable a highly accurate positioning of the components.

 

Materials

The MISUMI centering pins are available in the following materials: steel, stainless steel, aluminum, plastic . Pins made of steel and aluminum are available in both hardened and coated versions. With a high number of cycles, the use of a hardened material is recommended, as these have a higher wear resistance.

 

Corrosion resistance

The following salt water spray test was performed on the raw material (see table) of the centering pins and mounting pins. Corrosion resistance was determined based on the test times of 48 and 96 hours.

Shear load in comparison

During a test procedure, the shear load of a centering pin was tested with different steels. The tested centering pin was based on JPBB8-10 and was tested for a shear load in a device (see figure). The following table lists the test results for comparison purposes.

Coatings

MISUMI locating pins are available in burnished, hard chrome-plated or anodized to protect them from corrosion. Locating pins that have to withstand many cycles can be hard chrome-plated. The hard chrome plating provides a high surface hardness and provides the locating pin with high wear resistance. The selectable polished surface also ensures good surface roughness of the cylinder pins and helps to achieve good sliding properties. Aluminum locating pins are translucent anodized to protect them from corrosion and wear.

Instructions for Use / Installation Information - Locating Pins / Positioning Pins / Centring Pins

 

Maintenance

To facilitate maintenance for the centering pins, V-shaped wear grooves can be applied to the centering pin. The 0.2 mm deep grooves serve as a wear indicator of the usable surface. This makes the visual wear on the centering pin comprehensible and makes it easier to maintain the accuracy of the device. The wear grooves of the centering pins are only available with hardened and round centering pins.
