Abstract

The invention relates to a resin diamond soft polishing pad safety performance testing device, which comprises a sample fixation unit and a torque loading unit. The sample fixation unit consists of a rack, the rack is equipped with a guide rail, a movable crossbeam and a base plate able to move along the guide rail is arranged on the guide rail from bottom up, the rack is equipped with a movable crossbeam power apparatus, a load sensor is fixed on the movable crossbeam, the movable crossbeam and the base plate are in flexible connection, both ends of the base plate are provided with guide rail locking apparatuses, and a sample board is connected to the base plate. The torque loading part includes a movable disc and a torque sensor fixedly connected to the movable disc, and the other end of the torque sensor is in connection with a torque generation mechanism. According to the invention, the sample clamping is standard and reliable, the operation is convenient, the test conditions are uniform, errors caused by human factors are eliminated, a minimum torque value of sample failure can be tested accurately, thus finding 4 weakest links involved in resin diamond soft polishing pad safety performance. Existing technologies can only detect the bonding strength of a working face and a mounting surface, so that the device and the method provided by the invention have stronger practicability.

Description

technical field [0001] The invention belongs to the field of testing the safety performance of abrasive tools, in particular to a method and device for testing the safety performance of resin diamond soft grinding discs. Background technique: [0002] Resin diamond soft grinding discs are mainly used for grinding and polishing stone, glass, floor tiles and other building materials. It consists of a working surface and an installation surface. The working surface is made of diamond, resin and other fillers, the mounting surface is made of the loop surface of the nylon hook and loop, and the working surface and the mounting surface are bonded together with an adhesive. When in use, the ring surface of the installation surface is attached to the Velcro belt of the mill head, and the head rotates to drive the resin diamond soft grinding disc for grinding. The high-speed rotation requires safety performance must be guaranteed. [0003] The safety performance of resin diamond sof...
