Description

Technical Field

[0001] The invention relates to the technical field of pulley processing, and in particular to an intelligent pulley processing machine tool. Background Art

[0002] Belt pulleys are hub parts, which are generally relatively large in size. The manufacturing process is generally based on casting and forging. Belt pulleys are mainly used in situations where power is transmitted over long distances. When producing pulleys, the inner and outer rings of the cast or forged round steel billets need to be deburred.

[0003] There are two common ways to deburr the pulley. One is pure manual grinding, which is usually done by hand-held simple grinding tools to finely grind the inner and outer rings of the pulley. Although the grinding quality is high, the efficiency is low. The other is mechanical grinding, which is done by driving a machine tool with a turning tool close to the wall area of ​​the pulley for simple grinding. Although this type of grinding method improves the processing efficiency, the deburring quality is difficult to reach the expected level. Therefore, how to improve the grinding quality of the pulley on the basis of improving the processing efficiency is a problem to be solved.

Because the baffle 63 blocks the end of the air pipe 3 64, the paint inside the storage box 60 will not be affected by the suction force. The other part of the suction force will pass through the filter plate 56 and act on the absorption box 58 at the end of the air pipe 2 57. The suction force absorbs the metal impurities generated by grinding below the absorption box 58, and finally enters the collection box 55 for storage, so that the waste materials are reasonably recycled and utilized, ensuring a clean working environment and reducing the waste of resources.

[0053] On the other hand, when the detection unit 44 detects that the regularity of the inner ring and outer wall of the pulley 2 is insufficient, the detector 47 will send a flip signal to the external motor to make the motor rotate in the opposite direction, so that the gas will be discharged outward from the middle tube 53. Part of the gas will be blocked by the one-way valve 59 inside the air pipe 1 54, and the other part will enter the interior of the air pipe 3 64 and push the baffle 63 downward to squeeze, and cause the baffle 63 to lose its cover on the end of the air pipe 3 64. After the gas enters the interior of the storage box 60, the paint will be discharged from the bottom of the storage box 60, and then sprayed onto the side wall of the pulley 2 to mark it, so that the staff can quickly find unqualified products among multiple pulleys 2 to ensure good processing quality.
