Thread Pitch Measurement Background:

Measurement of thread pitch is of great significance in many fields such as machinery manufacturing, automotive parts, precision instruments and so on. Pitch refers to the distance between the peaks or valleys of two adjacent threads, which directly affects the strength of the threaded joint, sealing performance and fit precision. Therefore, the accurate measurement of pitch is the key link to ensure the quality of threaded parts. Traditional pitch measurement methods include the use of tools such as spiral micrometers and thread calipers, but these methods have problems such as complicated operation and limited accuracy.

 Advantages of in-line projective dimensioning

Online projection size measuring instrument is a high-precision and high-efficiency measuring equipment, which enlarges the image of the object to be measured and projects it onto the screen by means of projection, so as to realize the accurate measurement of the object size.

(1) High-precision measurement

The In-Line Projection Dimension Measuring Instrument employs a high-precision optical system capable of achieving micron-level measurement accuracy. It can accurately measure the pitch by adjusting the focal length and magnification to clearly project the contour of the thread.

(2) Easy to operate

Compared with the traditional pitch measurement tools, the operation of the in-line projection size measuring instrument is much easier. Users only need to place the thread sample on the measuring table, adjust the focal length and magnification of the projector, and start measuring. In addition, some advanced in-line projection dimensioning instruments are equipped with automation and intelligent functions, which can automatically identify the thread profile, calculate the pitch, and generate a measurement report, further simplifying the measurement process.

(3) Versatility

The online projection size measuring instrument is not only suitable for thread pitch measurement, but also can be used to measure other geometric dimensions, shapes, defects and so on. It is equipped with a variety of measuring tools to meet different measurement needs. For example, in the automotive industry, it can be used to measure key dimensions such as shaft diameter and shaft length; in the lithium industry, it can be used to measure the outer diameter of cylindrical batteries, the coating thickness of coating machines, etc. This versatility makes the online projection size measuring instrument widely used in many fields.

(4) Real-time and high efficiency

Online projection size measuring instrument can realize real-time measurement on the line, which closely fits the production process. It can monitor the thread pitch in real time during the production process, detect and correct deviations in time to ensure product quality. In addition, it also has the function of batch copying, which can batch copy and arrange tools according to any quantity, direction and interval, greatly simplifying and accelerating the process of measurement and setting, and improving production efficiency.

(5) Wide applicability

The online projection size measuring instrument is suitable for different types of thread pitch measurement. Whether it is a normal thread, trapezoidal thread or serrated thread, etc., it can be accurately measured by the on-line projection dimensional measuring instrument. In addition, it is also able to measure threaded parts of different specifications and materials, which has strong versatility and adaptability.
