Clamping device

Abstract

The invention discloses a clamping device which comprises a supporting frame, the supporting frame is provided with a fixed clamping arm and a movable clamping arm, the lower ends of the fixed clamping arm and the movable clamping arm are respectively provided with a clamp plate, and the two clamp plates are arranged opposite to each other; and the fixed clamping arm is fixed at the supporting frame, the movable clamping arm is connected with a screw rod by a movable nut, the screw rod is connected with a drive motor, and the drive motor drives the screw rod to rotate. The clamping device disclosed by the invention has the advantages of simple structure and capability of realizing the automated clamping of sand cores, is easy to use, effectively improves the production efficiency, reduces the labor intensity, and effectively avoids the falling-off of sand cores in the process of coating the sand cores with paints by robots.

Description

technical field [0001] The invention relates to the casting field, in particular to a clamping device for clamping a mud core when the mud core is dipped and coated with paint. Background technique [0002] In the modern casting production process, in order to improve the casting efficiency and meet the requirements of modern production, most of the cores used in the casting process are manufactured by cold box core shooters, which are widely used in the foundry machinery industry. The core made by the cold box core shooter has the advantages of accurate size and smooth surface, so it is widely used in many foundry companies. [0003] In foundry production, after the cold box core shooter shoots the sand cores, it is necessary to dip-coat the surface of the sand cores, etc., but because many sand cores are large in size, it is difficult to do it manually. Therefore, for the larger sand cores, it is necessary to use a robot to complete the action. When the robot moves, a cla...

[0003] In foundry production, after the cold box core shooter shoots the sand cores, it is necessary to dip-coat the surface of the sand cores, etc., but because many sand cores are large in size, it is difficult to do it manually. Therefore, for the larger sand cores, it is necessary to use a robot to complete the action. When the robot moves, a clamping device is needed to clamp the sand core to prevent the mud core from falling off during the coating process, but there is no such Special clamping device to achieve this function
