The powertrain is the core component of the car, which is equivalent to the "heart" of the human body. Therefore, a well-planned powertrain measurement solution is critical to ensuring the quality and performance of the powertrain and even the entire vehicle. Measurements for the powertrain field generally show the following characteristics: Accuracy requirements High measurement frequency High clamping position repeatability, rapid temperature change control Data processing: one of cg&cgk, GR&R measurement difficulties: valve seat measurement The main components of the powertrain are basically divided into cylinders, cylinder heads, crankshafts, camshafts, pistons, connecting rods, intake manifolds, and exhaust manifolds. Among them, there are many measurement items such as cylinder heads such as cylinder heads. The powertrain's inspection program revolves around the core of the evaluation. All factors affecting the evaluation results must be considered comprehensively: clamping, stylus, measuring machine, temperature, measuring position, measuring points, measuring speed... Based on the strict and systematic measurement needs of powertrain users, measurement manufacturers often need to implement the entire measurement system through turn-key, so as to better realize the integration and optimization of resources, and ensure the measurement and response of the powertrain detection phase. adapt. In general, the implementation of a turnkey project requires technical consultation from measurement, accurate understanding of measurement tasks, planning and matching measurement models, design between measurements, selection of measurement procedures, preparation of part inspection programs, custom workpiece-specific fixtures, and The loading and unloading system and the training of operations are carried out in many aspects. Among them, Hexagon has accumulated a lot of experience, and has provided and implemented the system's power total transaction key solution for many well-known powertrain manufacturers around the world.

In general, the measurement for the powertrain includes three types: general purpose, metering chamber type and production site type. General-purpose measuring machines are generally used in the workshop site, placed in the measurement room in the workshop or through a separate hood to provide a basis for fast and accurate measurement, generally based on movable bridges, such as the Global series measuring machine; The measuring machine provides the entire manufacturing precision standard with ultra-high precision, which mainly completes the highest evaluation of the product approval stage and the accuracy identification tasks of some standard measuring tools, such as ultra-high precision PMM-C fixed bridge measuring machine; production site type The measuring machine is designed for on-site use in demanding workshops. It has higher detection efficiency in performance and is equipped with a temperature compensation system to resist the influence of temperature changes on the measurement accuracy. It also has good protection against the whole machine. The impact of dust and oil on the precision measurement system in the workshop. Which measurement system to choose should be judged based on the accuracy, efficiency, environment, measurement requirements, and even the budget.
