Assembly fixtures are production auxiliary systems used to position parts against defined datums, secure them safely and join them in the same geometric arrangement during every cycle. They reduce operator dependency, improve cycle organization and help maintain dimensional consistency in serial production.
Each system is engineered specifically according to part geometry, tolerances, assembly sequence, production volume, datum surfaces, clamping points, ergonomics, robot access and sensor requirements.
An assembly fixture is production equipment that positions one or more parts against defined datums, secures them and keeps them stable throughout the assembly operation.
Depending on project requirements, the system may include:
Ensure that parts locate against the same datums in every cycle and help limit dimensional variation.
Standardize loading and clamping sequences to support more consistent serial-production results.
Quick clamping, controlled loading and easy part removal help shorten assembly operations.
Defined part orientation, position and clamping sequence reduce differences between operators.
Poka-yoke details, pins, stops and sensors reduce the risk of incorrect orientation, missing parts or improper placement.
Replaceable modules can be added for new product variants or process changes.
Prepared with mechanical stops, pins and quick-action clamps operated by personnel.
Use pneumatic cylinders and valve systems for controlled and repeatable clamping at higher cycle speeds.
Applied to large or heavy components requiring higher clamping forces.
Designed according to robot access, sensors, part feeding and automation scenarios.
Use manual, pneumatic or motorized mechanisms to provide access to different surfaces of the part.
Allow different parts from the same product family to be assembled on one system using replaceable modules.
Each project is evaluated individually according to part geometry, assembly method and production scenario.
Part drawings, 3D models, tolerances, assembly sequence, production volume, cycle time and quality criteria are evaluated.
Locating pins, stops, clamping points, operator or robot access, sensors and error-proofing details are determined.
The supporting frame, machined plates, pins, bushings, stops and custom connections are produced according to technical drawings.
Components are assembled accurately, and paint, coating, black oxide or corrosion protection is applied where required.
Datum points, clamping movements, sensors, part loading and dimensional stability over repeated cycles are checked.
Trial assembly is completed with actual or sample parts, final adjustments are made and the system is handed over ready for use.
Product changes, new variants, wear, clamping problems, dimensional variation or capacity increases may require existing fixtures to be modified.
Following a technical inspection, the following works may be carried out:
Materials and equipment are selected according to accuracy requirements, cycle quantity, process type and operating environment.
Provide durable and cost-effective solutions for supporting frames and primary structures.
Used for locating pins, bushings, stops and precision components exposed to wear.
Can be considered where low weight, easy machining and fast modification are required.
Can be used in special projects requiring hygiene, humidity resistance or high corrosion protection.
Preferred where high cycle speed or controlled clamping force is required.
Part-presence sensors, position sensors, switches and error-proofing components can be integrated.
Projects are not limited to standard fixture structures; they are prepared according to actual part geometry, tolerances, assembly sequence, cycle time and operator or robot access.
Technical design, steel fabrication, precision machining, assembly, inspection and trial processes are managed within a single project. Mechanical, pneumatic, sensor-equipped and modular modifications can also be carried out on existing assembly fixtures.
