Positioning mechanism for wire cutting device

The positioning mechanism for the wire cutting device comprises a base, first motors are fixedly connected to the two sides of the upper end of the base, lead screws are fixedly connected to the output ends of the two first motors, and fixing rods are fixedly connected to the two sides of the other side of the upper end of the base. According to the clamping block clamping device, the hole groove is formed in the output end of the first pneumatic cylinder, the sliding rod of the first pneumatic cylinder can be driven by the second motor to do translational motion so that the clamped clamping block can be limited and fixed, when the damaged clamping block needs to be taken down, only the second motor needs to be started to rotate, and when the sliding rod is removed, the damaged clamping block is taken down. According to the device, when the clamping blocks are replaced, tools do not need to be used for assistance, the time consumption and the replacement simplicity degree are greatly improved, and the purpose
