Auto Industry

PMT Has Years of Experience in Measurement for the Automotive Industry.

China’s auto exports and annual sales take the lead in the world amid the rapid development of new energy vehicles. The nation is moving steadily toward a new phase of growth for its auto industry featuring intelligence, sustainability and innovation. Price war has become the norm since the rapid development of the market will inevitably bring fierce competition. However, the market has proved that car companies have been raising their competitiveness, and the trend has shifted from low-priced competition to applications of cutting-edge technologies, exceptional performance of products, and branding development.

Therefore, 3D measurement technology has been playing an increasingly important role in modern manufacturing. It can provide high-precision measurements for different sizes and shapes, which is of great significance for improving product quality and production efficiency.

Portable Measuring Arm

As an advanced 3D geometric measurement system, PMT portable measuring arm has a built-in counterbalance system which is specially designed for on-site inspection. The structure of the equipment is simple and balanced, thanks to its perfect equal arm length design, which delivers an outstanding arm-operating experience. It also has the advantages of no measurement blind zone, wide measurement range, real-time temperature compensation system and low power consumption. PMT portable arm is compatible with many measurement software and widely used in manufacturing industries as follows.

Reverse Engineering

In scanning clay sculptures or existing samples, the Alpha M 7-axis Scan Arm can quickly model with its collected data , which greatly shortens the design cycle.

 

The PMT ScanArm has the following advantages:

  • There is no need to paste the marking point on the surface of the workpiece, and the workpiece can be scanned directly after it is fixed.
  • Blue light scanning and probe detection can be switched at any time, and probe detection can ensure the hole position data is more accurate.

Car Components Measurement

The 3D inspection of car components by portable measuring arm can ensure dimensional accuracy and then the assembly processes would proceed with precision.

In the measurement of automobile parts, it is often difficult to locate the part and inspect the space dimension, and the PMT measuring arm can help avoid such problems.

  • When measuring car parts, a coordinate system can be established easily based on the features of the measured object, without considering whether it is in the horizontal or vertical direction, as long as it is stably fixed.
  • The object can be positioned on the fixture at shop floor. Use the coordinate system of the fixture to measure the thin-walled parts.

Tool Alignment

We can make adjustments to the assembly position according to the obtained accurate data of the auto parts so as to make sure the accuracy and quality of the whole process.

In batch but not automated production lines, some parts are positioned with special tools. When there are some positioning deviations, it can be detected and adjusted with the PMT potable arm.

There are diverse and practical installation methods, and the measurement can also be completed even during transportation.

There is a real-time coordinate display, which can fine-tune a single positioning part with the coordinate system of the workpiece.

Fixtures Measurement

In order to meet the design and factory requirements, the automobile fixture needs to go through the verification by CMM, and issue the relevant adjustment quantity and accuracy report. In particular, the welding fixture of automobile sheet metal generally has the characteristics of large detection range, dense tooling, and complex use environment. The application of PMT measuring arm in automobile fixture inspection significantly improves the detection efficiency, adapts to the complex environment, and is an important means to adjust the fixture accuracy and maintain the production accuracy of the process.

  • PMT measuring arm uses a built-in balance and 360° infinite rotation mechanical structure, which is simple and tiny in appearance, making the measurement more flexible. The installation and measurement while swinging the arm body are less interfered during the tooling process.
  • The overall circuit is highly integrated, low power consumption, and the dual batteries can ensure 12 hours of working time, so as to ensure uninterrupted work on the site with tight electricity.
  • With a temperature compensation system, PMT portable arm is able to respond to large temperature difference when measuring at shop floor, providing a guarantee for data stability.

New Energy Battery Case Measurement

PMT portable arm uses the method of selecting features and then collecting data, and only needs to touch the surface of the battery case with the probe and press the button to collect. It takes fewer points but can quickly obtain key data such as flatness, hole position and contour of the battery case.

  • PMT portable arm adopts the design of equal arm length to meet the measurement near the base area of the device, and can be installed closer to the battery housing, so as to maximize the effective measurement range.
  • With the aerospace-grade carbon fiber material, the whole machine is very light in weight so as to reduce the work intensity of long-time inspection work.

Coordinate Measuring Machine

IATF16949 quality management system plays a vital role in the automotive industry, as it ensures quality control and continuous improvement in the car manufacturing. In IATF16949 quality management system, coordinate measuring machine(CMM) is one of the key quality control tools. It is mainly used to measure and verify the geometric dimensions and shape of parts to ensure the product meet the design requirements. It can provide high-precision dimensional and shape measurements, which is of great importance for improving product quality and production efficiency. With its excellent performance, PMT FUTURE Bridge CMM provides high-precision, high-stability and high-efficiency measurement solutions for production sites, R&D centers and metrology rooms. PMT SPACE is an innovative measuring machine designed for shop floor.

As a reliable and high-precision measurement machine, PMT CMM provides technical support for the automotive industry in the following aspects:

Overall-size Measurement

With the continuous development of the automotive industry, the precision requirements of the car parts are becoming higher and more complex. Usually, traditional measurement tools can not meet certain standards when facing complex parts and geometric tolerances, which makes our surveyors headaches. The accuracy index of PMT CMM follows ISO 10360-2:2009 standard, so the accuracy is reliable. It can not only measure the accuracy of μm, but also measure the dimensions of various complex parts, and calculate the GD&T of the parts through simple data editing.

Overall-size Measurement

Increase Measurement Efficiency

PMT CMM supports one-button measurement, and all measurement tasks can be completed automatically through simple point alignment, which greatly reduces labor costs. The consistency of measurements can also be improved due to minimized human error.

Increase Measurement Efficiency

Process Control

Through regular measurements, the production process can be monitored, and deviations in production can be found and corrected in time. That ensures the stability and consistency of the production process. It allows us to detect potential quality issues in advance, avoid substandard products from entering the market, and reduce customer complaints and the risks of recalls. It can also identify weak links in the production process and take effective measures to improve the quality of the product and as well as production efficiency.

Process Control

Data Digitization

After finishing the part measurement, the report can be exported in PDF and other formats for storage and reference. It is also helpful to standardize the data management.

 

Data Digitization

As technology evolves, the automobile manufacturing is making progress.
