Automobile inspection tool accessories refers to the installation of parts or components that meet the independent design requirements according to the technical requirements and structural characteristics of the inspected parts according to the drawings. Standard parts, alignment, positioning, connection and fixing into components, parts, assembly of gage parts, and the process of parts becoming automobile gages are the assembly of automobile gages, parts assembly and final assembly. Let's learn about the design and manufacture of automotive inspection fixture accessories.

During the assembly process of automobile gage accessories, it is necessary to ensure the matching accuracy of combined parts and the positional accuracy between related parts. For parts with relative motion, it is also necessary to ensure the motion accuracy between them. The assembly accuracy and quality of automobile testing instruments directly or indirectly affect the efficiency of three-coordinate debugging, labor costs and normal use in the later period. Therefore, the assembly of automobile detectors is one of the important components in the detector manufacturing process.

Technical Requirements for Assembly of Automotive Gauge Accessories

The assembly technical requirements of the detection device mainly include the appearance, installation size and overall assembly accuracy of the detection device.

Requirements for Appearance Inspection of Automotive Gauge Accessories

1) Check the non-processed surface of parts for defects such as scale, rust, lack of flesh, trachoma, and slack.

2) The edge pattern on the surface of the inspection tool parts is required to be consistent and orderly, and the surface roughness should be carried out according to the drawing standard.

3) All chamfering of parts of the inspection tool should be done by mechanical chamfering (except for those that cannot be specially processed), chamfering and rounding of the same size of parts of the same batch See IT14 for dimensional tolerances; except for special requirements, the appearance of the inspection tool is blunt and angular 1X45 degrees.

4) For complex inspection tools, there are many parts, and the assembled parts need steel stamps or mechanical automatic marking (pneumatic marking or laser marking). The non-working surface has obvious part number or component number information, which is convenient for fixture identification and avoids wrong or missing installation of similar parts.

5) Copper rods, rubber hammers and other soft material tools must be used for parts assembly to avoid damage to parts. The screw tightening torque during assembly is strictly in accordance with the specified value on the drawing. Assemble when some precision structures are required, and formally install after confirming that the installation connection structure is reliable.

6) Before and after assembly, there should be no obvious burrs on the edge of the mold, etc., and the edges and corners should be blunt to avoid scratching the operator's body when using it. The installation reference surface should be smooth, flat, free of rust, scratches and obvious surface processing defects. The heads of all screws and the ends of cylindrical pins should not be higher than the mounting plane. Usually, please be more than 1MM lower than the installation plane.

Assembly work content of automobile inspection fixture accessories:

In order to carry out the assembly work effectively, the bottom plate of the automobile inspection part is generally used as the main body, and the inspection part is divided into several assembly units, and each layer is determined according to the division of the assembly units The assembly sequence of assembly units constitutes the process system for assembly of automobile inspection parts.

Automobile gage fittings should first select the reference component to be assembled, and the reference component can be a component or a next-level assembly unit. The standard parts are assembled first, and then according to the specific conditions of the assembly structure, the assembly sequence of other parts or assembly units is determined according to the general rules.
