Breakage-proof precise clamping device for refractory bricks

The utility model relates to the technical field of refractory brick production, in particular to an anti-breaking precise clamping device for refractory bricks. The device comprises an air cylinder, two clamping jaw assemblies which are driven by the air cylinder to move relatively at the same time are arranged on the air cylinder, the two clamping jaw assemblies respectively comprise jackscrews arranged on respective moving paths of the clamping jaw assemblies, and when the air cylinder drives the two clamping jaw assemblies to be close to each other, the jackscrews are screwed into the clamping jaw assemblies. The jackscrew can abut against the air cylinder to limit the clamping jaw assembly according to the preset installation position. According to the scheme, the jackscrew capable of being adjusted in a screwed mode is adopted to control the moving distance of the clamping jaw assembly driven by the air cylinder, then the clamping force is controlled, and damage-free carrying of refractory bricks is ach
