What is a test fixture?

Inspection jigs are used to inspect parts (workpieces), assemblies in intermediate or final operations in the technological production process.

There are many inspection jigs depending on the purpose of use for example: dimensional check jigs, profile check jigs, surface quality check jigs, part flaw check jigs assembly process, etc., but all types of test jigs have the following basic structures:

  • Jigsaw body
  • Positioning mechanism
  • Clamping mechanism
  • Measuring and checking structure
  • Other sub-structures

Steps to use test fixture

Step 1: Place the part to be checked on the fixture

Step 2: Put the jig in the correct working position of the assembly, detail or machine (available positioning part of the jig)

Step 3: Use the clamping mechanism to fasten the fixture to the part to be checked

Step 4: Conduct product inspection as required

TITLE

Causes of errors during the use of test jigs

When manufacturing test jigs, attention must be paid to all causes of errors:

  1. Standard error and clamping error when measuring
  2. Fixture adjustment error
  3. Error due to worn jigs
  4. Error due to temperature change when testing

Testing can minimize or eliminate those influencing factors to get the most accurate test effect.
