The application of IMS three-seat measuring machine in general machinery industry!
As an important part of the equipment manufacturing industry, general machinery plays a very important role in the national economic construction. In the context of the overall slowdown of the machinery industry, the general machinery industry has maintained steady growth, and the innovation ability of enterprises has also been enhanced.
At present, the level of automation of the general machinery industry still needs to be improved, high labor costs have begun to restrict the development of the industry, the application of automation technology to reduce costs is the only way for general machinery enterprises to achieve transformation breakthroughs. Therefore, major enterprises are competing to join the wave of "machine replacement" and automation transformation and upgrading, and the incremental potential for intelligent production demand in the industry is huge.
In a variety of mechanical devices, shaft parts are an important part, radial dimensional accuracy and shape accuracy requirements are high, is the key link to grasp the quality of the product, but also to ensure that the coaxiality of the bearing journal, as well as the mutual position of the coaxiality and circular runout, so it is necessary to constantly strengthen the accurate inspection of shaft parts. As the market constantly puts forward new and higher requirements for high-precision shaft products, how to improve the measurement accuracy of drive shaft and gear shaft is a common concern in the automobile manufacturing industry.
传统测量设备的弊端：
For the measurement of high-precision shaft parts, the traditional point-type coordinate measurement has few points and low efficiency, which is difficult to meet the needs of high-intensity and high-precision measurement. Based on this high-precision requirement and difficult size measurement, IMS introduced a continuous scanning measurement solution for gear shafts.
STAFF coordinate measuring machine advantages:
1, STAFF CMM is widely used in precision shaft parts, gear detection, is a model designed for complex surface detection, with IMS SCAN1 continuous scanning sensor, support hard trigger scanning function, needle length up to 200mm or more, convenient for deep hole measurement, support self-centering measurement and continuous high-speed scanning measurement. Hundreds of points can be collected in a few seconds, several times more efficient than the previous detection, to achieve high-speed, high-precision continuous sampling.
2, reliable hardware scanning:
In the detection, the common axis of the two cylinders is used as the benchmark, because the shaft parts are mostly slender, it is not good to stand the clamp, so the V-shaped block is used to reduce the installation times of the cone plug, so as to reduce the repeated installation error of the parts, the two supporting shaft necks of the parts are placed on the V-shaped block to pad the high profile flat, after scanning the tested elements, the output measurement of cylindricity, runout, coaxiality and other data.
IMS-DMIS CAD++ has a variety of scanning methods for cylindrical scanning to cope with various scenarios, so as to complete the detection more conveniently, quickly and highly accurate.
3, super powerful software customization function:
The center hole of the workpiece is the positioning benchmark and the inspection benchmark of the processing process. The common configuration scheme of the benchmark axis is easy to measure, but the traditional point-type measurement of the center position of the tooth will cause a certain degree of deviation, and the center position cannot be determined, so the scanning probe + self-centering function measurement is required. IMS-DMIS CAD++ self-centering function can effectively solve this problem, the so-called self-centering means that when the measuring needle contacts two sides at the same time, the software automatically records the center position of the measuring needle, IMS-DMIS CAD++S custom rotation center, find the tooth center, convenient and efficient completion of the detection.
Summarize：
Two scenarios for hard contact scanning measurement are described below:
1. Phase Angle measurement
The tooth shape of each group of double gear should maintain the phase relationship, and the Angle between the axis and the corresponding upper and lower tooth center of each group should be controlled. As shown in the following figure, the phase Angle is required to be ±0.1°, and the self-centering function is used to accurately obtain the center position of the two teeth, so that the Angle can be accurately measured.
2, in the processing and measurement of the shaft end keyway, the symmetry of the keyway relative to the benchmark of the axis is difficult to measure, application scenarios
The following two scenarios are described:
1), phase Angle measurement
The tooth shape of each group of double gear should maintain the phase relationship, and the Angle between the axis and the corresponding upper and lower tooth center of each group should be controlled. As shown in the following figure, the phase Angle is required to be ±0.1°, and the self-centering function is used to accurately obtain the center position of the two teeth, so that the Angle can be accurately measured.
2) In the machining and measurement of the shaft end keyway, the symmetry of the keyway relative to the axis is difficult to measure, IMS-DMIS CAD++ self-centering function is based on the axis and the center of the tooth or the center of the two teeth, which is convenient to accurately measure the symmetry of the keyway. As shown below:
3. IMS-DMIS CAD++, which is equipped with self-centering function of STAFF coordinate measuring machine, can directly measure the above two scenarios, which can automatically and accurately obtain the center position of two teeth, fully meet the measurement requirements, and well solve the precision measurement requirements of gear shaft. The detection process is convenient and fast, and the measurement is more accurate and efficient. It can also be extended to the detection of fixed diameter ball lanes (which can be customized with a specified diameter needle), pitch circles, etc
The self-centering function is based on the axis and the center of the tooth or the center of the two teeth, which facilitates accurate measurement of the symmetry of the keyway. As shown below:
