Unlike the traditional probe and laser measurement system, ECM uses visible light imaging technology. First, the measured object is projected and then analyzed according to a number of projection data. After the analysis, the size, shape and position of the product can be automatically obtained, which are related to bolts and revolving bodies.
Application Cases
Model
The role of the bolt is to tighten, and it is conceivable that the preload (clamping force) is the most important measurement parameter. However, the pre-tightening force can not be directly measured like torque. It can only be measured by indirect method. The measuring method is also varied. The traditional method includes strain gauge method and washer sensor method, while ultrasonic wave is used to measure the pre-tightening force compared with other methods. The method does have many advantages, and can achieve non-destructive measurement, real measurement, information preservation, and cost saving.

Practice and theory are the left and right legs of human knowledge learning. Recently, Xiao Yan discovered that the left leg of the domestic fastening industry has become more and more sturdy, but the right leg is somewhat thin, and the theory is more or less lacking, including Xiao Yan himself. It's time to arm yourself with theory, and there is a book that will hold you armed.

Maximum quality and process reliability in bolting technology
In virtually every sector of industry, assembly with bolts and screws is one of the most frequently used joining processes in manufacturing. That's why it's crucially important for bolted joints to function safely and reliably – otherwise, there will be the risk of recalls and additional costs. To maximize quality and cut costs, fastening technology must be continuously monitored and tested. And to achieve this, Kistler offers an extensive portfolio of test and analysis systems. They analyze the functional characteristics of bolted joints (such as the coefficient of friction, preloading force or torque) and also bolting tools; they capture all the measured values and provide a clear presentation of the documented results. These systems allow targeted monitoring of tolerance limits, and they ensure that process deviations in fastening technology are detected at an early stage.
The friction coefficient control of bolts and nuts in assembly process has an important influence on the quality of bolted connections. The friction coefficient tester ensures the stability and high quality of bolt assembly by analyzing the friction coefficient.
The simulation assembly system can be used to study the actual assembly performance of fasteners under actual assembly conditions.
In order to achieve reliable bolting in modern industrial processes, reliable tightening of the gun is essential. Not only must the tightening gun be calibrated and certified prior to assembly, but it must also be tested repeatedly during assembly. The goal is to ensure continuous high performance in order to achieve optimal assembly results and meet established standards.
Ultrasonic bolt axial force measurement system is a simplified bolt axial force control tool. By measuring the actual tightening bolts with the calibration bolts and ultrasonic waves, a clamping force of up to ±3% accuracy can be obtained. Away from the torque method, the clamping force is greatly different, which is your preferred engineering solution.
Whether it's a sample inspection during the process or a continuous inspection of the tightening gun and torque wrench, accurate and rapid access to measurement data is key to improving product quality and optimizing the process. Our compact inspection system uses state-of-the-art hardware and software to continuously acquire and display torque and corner measurement data. Users benefit: judge the quality of parts that have been produced to identify potential weaknesses and challenges early in the production process.
The quality characteristics of the bolts and nuts during installation have a direct impact on the quality of the bolted connections. Functional testing is the most important analytical method used in the assembly process. It determines the mechanical properties and functions of the fastening parts to ensure their quality. Also determine the coefficient of friction, preload and torque. In the process, we comply with international standards and simulate the conditions of use as realistically as possible.
Comfort test system can quantitatively test the comfort of door, trunk, seat, engine hatch, shift rod, glove box, sunshade, steering force, switch button, pedal and a series of "human-vehicle interaction" parts to ensure the realization of the best ergonomics.
Mechanical testing machine is specially designed for tension, compression, bending, shearing and torsion tests, which can meet the highest requirements of mechanical properties related testing.
