Description

Technical Field

[0002] The high-precision inspection fixtures for copper busbars and plastic bases of new energy vehicles are made of materials such as AL6061 and Cr12MoV to ensure a processing accuracy of ±0.02mm. The inspection fixtures are equipped with locating pins, pilot holes, etc., and can achieve precise measurement of shape, position and thread through special go / no-go gauges and detection pins, which are suitable for product quality control and accuracy assurance.

[0003] When testing the high-precision inspection fixture for copper busbars and plastic bases of new energy vehicles, first assemble the product onto the inspection fixture, use holes and positioning pins for positioning, then insert the fixed parts into the guide holes of the die base to ensure stability, then use the nut detection pin and pin detection block to detect the position accuracy of the pins and nut holes, and finally insert the shape detection block into the guide holes of the die base to detect the product's shape dimensions; Copper busbars are key parts of the electric control assembly of new energy vehicles. They are divided into positive copper busbars and negative copper busbars. Copper busbars are responsible for transmitting high currents, so they need to be tested with high-precision testing tools. The materials that high-precision inspection tools for copper busbars and plastic bases of new energy vehicles contact are relatively delicate to install. In the production workshop, dust may be generated during processing and manufacturing. This dust may drift to the surface of the inspection tool and then adhere to the surface of the inspection tool. If it is not cleaned in time, when tools such as go and no-go gauges and detection pins are used to contact the surface of the inspection tool, dust particles will hinder the smooth contact between the tool and the surface of the inspection tool. Dust on the rough surface will produce more friction resistance. When the go and no-go gauge is used to detect the aperture, the change in friction may cause the go and no-go gauge to pass or stop inaccurately, thereby affecting the judgment of the aperture size and the accuracy of detection; Therefore, in order to solve the above problems, a high-precision inspection tool for copper busbars and plastic bases of new energy vehicles and a method for using the same are proposed.
