The invention provides an automatic dismounting and mounting device for a wringing roller bearing. The automatic dismounting and mounting device comprises a rack, and a bracket unit for supporting a wringing roller is arranged on the rack; a bearing dismounting assembly or a bearing mounting assembly is arranged at each of the two ends of the rack; the bearing mounting assembly comprises a bearing mounting pressing cylinder capable of moving along the working axis; and the bearing dismounting assembly comprises bearing dismounting baffle bases and bearing dismounting ejector heads capable of moving along the working axis, and bearing baffles capable of ascending and descending are arranged on the bearing dismounting baffle bases. In the dismounting or mounting process, only the bearing mounting pressing cylinder in the bearing mounting assembly or the bearing dismounting ejector heads and the bearing baffles in the bearing dismounting assembly need to be driven to move, time and labor are saved, the wringing roller is not damaged in the working process; and meanwhile, mounting and dismounting of wringing roller bearings different in length specification can be achieved by replacing the bearing mounting pressing cylinder on the bearing mounting assembly or replacing the bearing dismounting ejector heads and the bearing baffles on the bearing dismounting assembly.
Description
technical field [0001] The invention relates to the field of squeezing rollers, in particular to an automatic dismounting device for squeezing roller bearings. Background technique [0002] Squeeze rolls used in cold rolling of steel often need to be sent to equipment repair plants for routine maintenance and repairs. Squeezing rollers are of different models and lengths, but the structure is roughly the same, including a roller, a mandrel, a built-in bearing cavity located at both ends of the roller, and a bearing installed on the mandrel and interference-fitted with the bearing cavity. bearings. When the squeeze roller goes off-line for repair every time, the bearings at both ends must be disassembled, and then reinstalled after cleaning and inspection. [0003] In the prior art, the process of dismantling the bearing is as follows: first, a hydraulic jack is used to act on one end of the mandrel, so that the bearing at this end of the mandrel is separated from the mandr...
