The invention discloses a
polishing device for
power cable protection
pipe production, and belongs to the field of protection
pipe production, the
polishing device comprises a base, the upper end of the base is fixedly connected with a fixing plate, the middle part of the fixing plate is provided with a circular through hole, and the middle part of the base is provided with a
slag falling hole; and the upper end of the base is fixedly connected with a mounting plate. The hydraulic telescopic rod drives the conical block to be matched with the inclined face of the positioning block, self-adaptive centering clamping of
power cable protection pipes with different diameters is achieved, the coaxiality of the protection pipes in the
grinding process is ensured, and the
grinding precision is effectively improved; meanwhile, the elastic reset design of the spring A and the spring B is matched, full-process
automation of clamping, feeding and resetting is achieved, manual repeated adjustment is not needed, the clamping and part taking efficiency is greatly improved, part
impact is avoided through the buffering effect of the springs, the service life of the device is prolonged, the structure is simple and reliable, adaptability is high, and the production cost is low. And a stable positioning foundation is provided for subsequent
polishing operation.
