[0002] Springs are a common part in our daily production. They are needed in everything from ballpoint pens to machine tools. Springs are often made of spring steel. After the spring is produced, it is necessary to spray anti-rust paint on the surface of the spring for rust prevention. However, in order to ensure the good effect of the anti-rust paint spraying, the spring needs to be ground. The existing grinding device generally requires manual internal grinding of the spring, which occupies manpower for a long time and has low efficiency. Therefore, it is particularly necessary to develop a high-quality and efficient grinding device for spring production that can replace manual labor, save manpower and has high efficiency.

The driving mechanism 4 is fixedly arranged on the vertical plate 3, and the driving mechanism 4 drives the transmission shaft 2 to rotate. The driving mechanism 4 is a variable frequency motor, and the variable frequency motor controls the forward and reverse rotation by frequency conversion, thereby driving the transmission shaft 2 to rotate forward and reverse.

[0022] The end of the transmission shaft 2 is detachably connected to a grinding column 5, which extends coaxially with the transmission shaft 2. A spiral groove is provided on the side of the grinding column 5, which is used to adapt to the pitch of the spring. The size of the spring to be ground at the root can be replaced with a different type of grinding column 5, which has strong adaptability.
