Abstract

This paper presents the design of a trapezoidal piston ring end face angle detection instrument, which is crucial for ensuring the quality and performance of piston rings in internal combustion engines. The detection instrument is designed to accurately measure the end face angle of trapezoidal piston rings, which directly affects the sealing performance and operational efficiency of the engine.

1 Introduction

The performance and durability of internal combustion engines are significantly influenced by the quality of piston rings. Among various types of piston rings, trapezoidal piston rings are widely used due to their excellent sealing properties. Accurate measurement of the end face angle is essential for ensuring optimal performance and longevity. This paper focuses on the design and development of a detection instrument specifically tailored for trapezoidal piston rings.

2 Design Requirements

The design requirements for the trapezoidal piston ring end face angle detection instrument include high precision, reliability, and ease of use. The instrument must be capable of measuring angles with an accuracy within ±0.1° to ensure that the trapezoidal piston rings meet stringent quality standards.

3 Instrument Design

3.1 Structural Design

The structural design of the detection instrument consists of a base frame, a rotating mechanism, a measurement head, and a data acquisition system. The base frame provides stability and support for the entire instrument. The rotating mechanism allows for precise angular positioning, while the measurement head is equipped with sensors capable of detecting subtle changes in angle.

3.2 Measurement Head

The measurement head is designed to securely hold the trapezoidal piston ring in place during measurement. It features a clamping mechanism that ensures consistent positioning and prevents any movement during the measurement process. Additionally, it includes sensors that can accurately measure small changes in angle.

3.3 Data Acquisition System

The data acquisition system is responsible for collecting and processing measurement data. It consists of an analog-to-digital converter (ADC) and a microcontroller unit (MCU). The ADC converts analog signals from the sensors into digital format, which is then processed by the MCU to provide accurate readings.

4 Testing and Calibration

To ensure the reliability and accuracy of the detection instrument, rigorous testing and calibration procedures are conducted. These procedures include environmental testing to ensure that the instrument performs consistently under various conditions, as well as calibration tests to fine-tune its measurements.

5 Conclusion

The design of a trapezoidal piston ring end face angle detection instrument has been successfully completed with emphasis on precision, reliability, and
