[0002] Before leaving the factory, the end faces and inner rings of reinforced concrete drainage pipes must be polished and deburred to ensure high connection accuracy. At present, most manufacturers still rely on manual use of handheld angle grinders to perform this operation, but this method is inefficient and labor-intensive. In order to improve this situation, we have proposed a two-end grinding device dedicated to reinforced concrete drainage pipe production lines, which aims to complete this process automatically, thereby improving production efficiency and reducing the burden on workers.

By setting an inner ring grinding body and an end face grinding body, under the joint action of a hydraulic telescopic rod, a turntable and a rotating motor, it can realize the purpose of automatically grinding the end face and inner ring of the drainage pipe body at the same time, which not only improves the grinding efficiency but also reduces manual labor. By setting long holes, the position of the inner ring grinding body can be conveniently adjusted to realize the compensation function for the wear of the grinding rod. By setting a strong spring, the grinding rod can be effectively prevented from breaking when encountering a hard object during work, so as to achieve a protective purpose.
