Tacho Plate’s Technological Procedure Compilation and the Fixture’s Digital Design

Abstract:

Tacho plate is a common speed regulation mechanism in automobile, but because of its complex structure, high precision, there has been no ideal processing method. Based on the Pro.E, this paper compiles the processing technic of the Tacho plate which combining with the practical situation and comprehensive considering the precision, economy, efficiency, roughness, lifetime and other factors, and digital design a specific work fixture regarding one of the most important procedure. Eventually it achieves a very satisfactory result. First of all, understand the working condition of Tacho plate through on-the-spot investigation, reviewing the literature and some other methods, and then preliminary analyze the processing technic of Tacho plate. Secondly, constantly improve the processing technic of Tacho plate through in-depth analysis of the actual situation and comprehensive considering the machining precision, economic benefit, efficiency and some other aspects to make the best processing procedures. Furthermore, make in-depth analysis for the fixture of drilling Φ10 hole. Considering the machining accuracy, use the ganged clamping mechanism with the support plate, regulative support nail, and rhombic pin for joint locating to meet the requirements to the greatest extent. Finally, use the Pro.E software for three-dimension model and further verify the fixture plan designed before through this digital design.
