Product Overview
The fixture bushing is a mechanical positioning part that is used in conjunction with a positioning pin to achieve a guiding effect. The straight falloff prevention type can effectively prevent falloff and control mounting position, and can effectively prevent the rapid wear of the workpiece.
Dimensional Drawing
Fixture bushing dimensional drawing and diagram
The p7 type has a larger inner diameter shrinkage rate compared to the m7 type, so be careful when machining holes. (See Precautions for the inner diameter change after press-fit)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, straight falloff prevention type, can be fixed by bolts laterally to effectively prevent falloff.
Feature 2: electroless nickel plated and austenitic stainless steel types can effectively prevent rust.
Feature 3: optional material: iron (alloy tool steel or bearing steel); austenitic stainless steel (martensitic stainless steel); austenitic stainless 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.
