A silicon rod clamping device is disclosed in the Chinese utility model patent with the application number CN202420934865.4, which comprises a crossbeam, a sliding block, a driving mechanism, a main clamping jaw and an auxiliary clamping jaw. Two sliding blocks are slidably connected on the crossbeam along the length direction of the crossbeam. The driving mechanism is used to drive the two sliding blocks to move towards each other or away from each other. A main clamping jaw is fixedly connected on each sliding block. V-shaped main clamping surfaces are arranged on the opposite sides of the two main clamping jaws. A sliding groove is formed on the main clamping surface. An auxiliary clamping jaw is slidably connected in the sliding groove of each main clamping jaw. The sliding direction of the auxiliary clamping jaw is parallel to the sliding direction of the main clamping jaw. Auxiliary clamping surfaces matching the main clamping surfaces are arranged on the opposite sides of the two auxiliary clamping jaws. Right-angle grooves are formed on the two surfaces of the auxiliary clamping surface. An oil cylinder is installed on the main clamping jaw to drive the auxiliary clamping jaw to move. The utility model can clamp round rods and square rods, has high adaptability, can effectively save the investment of equipment and improve the economy.
