automobileInspection tool accessoriesThe design is generally made of chemical materials or textile fabrics, which have many different characteristics compared to body parts. Due to its large size, complex surface and structure, poor stiffness of parts, and multiple spatial dimensions, it is necessary to use testing instruments for comparative measurement in order to quickly and accurately evaluate the quality of product parts. At the same time, detection instruments are beneficial for discovering problems in the process route of components, ensuring the continuous improvement of product process routes. Detection instruments play an important role in the smooth production of automobiles. A preliminary exploration was conducted on the inspection tools for large decorative items in automobile production.

Design principles for automotive inspection tool accessories

The design of automotive inspection tool accessories must have sufficient rigidity, stability, and measurement accuracy to ensure the quality of the vehicle; The operation should be easy to ensure sufficient measurement efficiency; The structure should be used as simply as possible; Having a good appearance; It is necessary to ensure sufficient economy for vehicle cost management as well as ease of measurement and calibration.

Key points of design for automotive inspection tool accessories

The design of automotive inspection tool accessories has both the commonality of automotive component testing instruments and its own characteristics. In its structure, it mainly consists of the following parts. Bottom plate and frame parts, positioning devices, clamping devices, measuring devices, auxiliary devices, etc.

1. Bottom plate and rack design

The bottom plate and frame are the basic parts of the entire detector, not the working parts of the detector, and their stability directly affects the accuracy of the entire detector. The inspection tool for large decorative items is relatively large, and when designing the base plate and frame structure, attention must be paid to the rigidity and the processability and stability of the selected materials. At present, cast aluminum material is used, and a ribbed plate structure or box structure is adopted. Set inspection and acceptance standards for inspection tools on the base plate, so that it can be associated with the coordinates of the vehicle. At the same time, set up lifting or handling structures, and set coordinate lines for automotive components on the base plate. The size of the product itself is large, and the design of the base plate cannot be too large. Causing inconvenience in operation. As long as it can prevent the flipping parts from coming out of the base plate.

2. Design of positioning device

Automotive components are generally spatial components, and their positioning in space plays a decisive role in the accuracy and stability of their detection. In actual production, there are no real points and lines, and they are generally approximated by the unit "surface". The size of one side depends on the size of the product. When inspecting large decorative items, the configuration status of the inspection tool should be in the loading state to avoid the influence of the gravity state of the flexible body on the inspection results.

3. Design of clamping device

In order to ensure the characteristics of large decorative items and the condition of the parts on the inspection tool during inspection, after placing the parts on the inspection tool, a clamping device is used to provide a certain degree of rigidity for the zero point positioning surface and the inspection tool positioning clamping device. The clamping direction is along the normal direction of the positioning surface, and there are various types and structures of clamping devices in both directions. The general principle is to operate as conveniently and quickly as possible, and use standard parts as much as possible, while ensuring the structural permission of the clamping parts and inspection pieces.
