Bushings for Locating Pins Shouldered, Slotted Hole

Product Overview
The fixture bushing is a mechanical positioning part that is used in conjunction with a positioning pin to achieve a guiding effect, in which the slotted hole, shouldered type product has a large space in the long direction for easy insertion of pins to absorb clearance errors, with its shoulder supporting the body, and can effectively prevent the rapid wear of the workpiece.
Dimensional Drawing
Fixture bushing dimensional drawing and diagram
The I.D. tolerance of bushing is high. If a vernier caliper is used for detection, the measurement result will be too small. It is recommended to use a high-precision measuring tool (internal micrometer or plug gauge, etc.) for detection.

Product Features
Features and usage outline of fixture bushing product Jig Bushings Shoulder Standard
Feature 1: fixture bushing, slotted hole, falloff prevention type, is easy to insert pins in the long direction and can absorb clearance errors. The crown shape at the shoulder prevents falloff.
Feature 2: electroless nickel plated type can effectively prevent rust.
Feature 3: optional material: iron (alloy tool steel or bearing steel).
Feature 4: press-fit installation, the tolerance of the O.D. press-fit dimension can be specified: p7, m7.
Precautions
①Dimensional tolerance and fit parameter table For details, click Dimensional Tolerance Fit Table
②Change in inner diameter of the fixture bushing during press-fit
■Change in inner diameter of the fixture bushing during press-fit
The fixture bushing shrinks when press-fitted.
The shrinkage rate varies depending on material of mounting part and D dimension tolerance of bushing.

Example of Use
Example of using bushing for positioning pin and example of fixture
Example introduction: shouldered bushing for positioning pin in pick and place mechanism
Design summary:
  ①An example of using a swing cylinder to achieve linear and rotary motion through pneumatic drive, and moving a small substrate through a suction cup.
  ②In the case of a long pin, if the air vent is not provided, the pin and bushing are not easy to pull out. It is necessary to provide a air vent on the bushing side or the positioning pin side.
Intended use of fixture bushing:
  The axial structure of the swing cylinder can ensure positioning accuracy while saving space through the coordination of positioning pins/shouldered bushings.
