RUBBER BLOCK PIECE CHANGE APPARATUS OF HIGH SPEED FRICTION TESTER FOR RUBBER BLOCK PIECE

摘要

The present invention relates to a rubber specimen replacing device capable of automatically replacing and mounting a new rubber specimen after testing a rubber specimen in contact with the road surface with a device for testing high-friction properties of a rubber specimen. The rubber specimen replacing device which replacing the rubber specimen (2a) utilized for a test into the new specimen (2b) after testing the rubber specimen by to touching the rubber specimen (2a) mounted on a jig of a transfer unit (1) which is linearly moved along a linear guide includes a pneumatic cylinder (5) for replacing the rubber specimen which is installed on supporting frames (4) on both sides of the transfer unit (1) when the transfer unit (1) is at a right position of the linear guide and a pneumatic cylinder (6) for supporting the rubber specimen which are separately installed in the horizontal direction. A rubber specimen fixing bracket (7), which is connected to the front end of the pneumatic cylinder for replacing the rubber specimen and installed on the front end of the pneumatic cylinder (5) for replacing the rubber, locks the new rubber specimen or releases the locked new rubber specimen by being vertically moved by the pneumatic cylinder (8) for holding. A rubber specimen fixing bracket (7) is connected to the front end of the pneumatic cylinder (6) for supporting the rubber specimen and vertically moved by the pneumatic cylinder (8) for holding, thereby locking the utilized rubber specimen (2a) or releasing the locked rubber specimen.
