[0002] After the computer flat knitting machine insert is formed, its thickness needs to be measured. However, the computer flat knitting machine insert is a special-shaped part, and there are three or more thickness measurement positions on it. There are great limitations when using a common wall thickness gauge to measure it. When a worker holds the wall thickness gauge to measure, it is very inconvenient to operate during the process of aligning the measurement positions one by one due to the shape of the computer flat knitting machine insert. Moreover, due to the influence of factors such as holding it obliquely, it is very easy to cause inaccurate measurement. Therefore, it is particularly important to design a thickness detection device for computer flat knitting machine insert processing to solve the above problems. Summary of the Invention

Through the driving of the first translation driving electric cylinder and the second translation driving electric cylinder, the first placing seat and the second placing seat can be conveyed to between the laser displacement sensors on the first L-shaped bracket and the second L-shaped bracket one by one. The thickness of the computer flat knitting machine insert in the placing groove can be directly measured by the laser displacement sensors on the upper and lower sides. By adopting the above structure, automatic measurement is achieved, the measurement is very convenient and fast, and the measurement accuracy is also very high.
