Types Of Checking Fixture

The checking fixtures produced by our company mainly include the following types:

Stamping Part Checking Fixture

A Stamping Part Checking Fixture is a custom-built, high-precision quality control tool used to verify the dimensional accuracy, shape, and fit of complex metal-stamped components (like car body panels) after they're made, ensuring they meet strict specifications for "GO/NO-GO" acceptance, preventing defects and ensuring consistency in manufacturing.

Plastic Part Checking Fixture

A Plastic Part Checking Fixture is a custom-built quality assurance tool used to verify if manufactured plastic components meet precise design specifications, dimensions, and assembly requirements, acting as a "Go/No-Go" gauge that holds the part to check for defects like warpage, gaps, or misalignments, ensuring consistent quality in industries like automotive and aerospace.

Automotive Cubing Fixtures

Automotive cubing fixtures (or Meisterbocks) are full-size, highly precise, machined reference frames (often aluminum) that simulate a car's interior/exterior structure, used by engineers to check fit, function, and assembly of serial parts (doors, panels, seats, etc.) early in design, ensuring parts from different suppliers align perfectly before mass production, saving time and catching errors fast.

Advantages of Checking Fixture

Enhanced Quality Control

By providing a precise and reliable means of inspection, these fixtures help maintain high quality standards.

Reduced Rework

Early detection of defects allows for timely corrections, reducing the need for costly rework or scrapping of parts.

Consistency

Ensures that all panels produced are consistent and fit perfectly during the assembly process.

Efficiency

Streamlines the inspection process, enabling faster production times without compromising on quality.

Applications of Checking Fixture

Automotive Parts Assembly

Checking fixtures are widely used in the automotive industry or other industries to verify dimensions of components such as chassis elements, and interior fittings. They ensure that parts fit together correctly during assembly and meet stringent performance standards.

Mass Production Environments

If there are large quantities of identical or similar parts are produced, checking fixtures provides a cost-effective solution for ensuring uniformity and precision. This is crucial for meeting production targets without compromising on quality.

Replacement of Specialized Measuring Tools

Checking fixtures serves as a versatile alternative to specialized measuring tools like plug gauges and OD gauges. They offer simplicity in operation while still delivering accurate measurements, making them suitable for a wide range of manufacturing applications in automotive,aerospace,electronics and so on.

Different Materials of Checking Fixture

Steel: Excellent strength, wear resistance, affordability; types include carbon, stainless, alloy for specific properties.

Aluminum: Lightweight, corrosion-resistant, good for aerospace/auto, easy to machine.

Plastics (Delrin, Nylon): For non-metallic contact, chemical resistance, low friction, lighter weight.

Resins/Epoxy

Ideal for complex shapes, customized components, casting.

FRP (Fiber Reinforced Plastic)

Lightweight yet strong composite.

Wood/MDF

Used for simpler or less demanding applications.

Brass

Durable, corrosion-resistant, good for electrical/non-sparking needs.

Installation Steps for Checking Fixture

01/

Unpack And Inspect The Fixture
Carefully unpack the checking fixture and inspect it for any damage or missing parts. If you find any issues, contact your supplier right away.

02/

Position The Fixture
Place the checking fixture on the chosen location and use a measuring tape to ensure it's properly aligned. Make sure the fixture is level and that it's positioned in the correct orientation for the part being checked.

03/

Secure The Fixture
Once the fixture is in position, use the appropriate fasteners to secure it to the surface. This may involve drilling holes and using bolts or screws. Make sure the fasteners are tightened securely, but be careful not to overtighten them, as this can damage the fixture or the surface.

04/

Install The Components
If your checking fixture comes with additional components, such as clamps, gauges, or sensors, install these according to the instructions. Make sure each component is properly aligned and tightened.

05/

Connect The Electrical Or Pneumatic Systems (If Applicable)
Some checking fixtures may require electrical or pneumatic connections. If this is the case, follow the instructions to connect the systems safely. Make sure all connections are secure and that there are no leaks.

06/

Calibrate The Fixture
After the fixture is installed and all the components are connected, it's time to calibrate it. Calibration is the process of adjusting the fixture to ensure it provides accurate measurements. Follow the calibration instructions provided by the manufacturer to set up the fixture correctly.

Customizable Options

Multiple variant support (with/without sensors, different trims).

Modular quick-change components.

SPC checking fixture compatibility for statistical process control.

Integration with optical scanners and digital reporting systems.

Expertise in plastic parts checking fixture and stamping parts checking fixture and Cubing Fixture design.

Packaging and Shipping

Packaging	The checking fixture is securely mounted onto a custom wooden or metal skid. It is then wrapped in anti-corrosive VCI film and placed in a reinforced wooden export crate.
Shipping	Shipping by sea, by air, by express are acceptable. According to your requirements.
