Abstract

The present application relates to the field of clamp technology, and discloses a quick clamp, including a fixed plate, the upper surface of which is fixedly connected to two symmetrically arranged support plates. This quick clamp, for round rod-type workpieces, significantly increases the contact area with the workpiece by designing a pressure roller with an incomplete conical groove, thereby effectively improving the stability of clamping. For block-shaped workpieces, the circumferential surface of the pressure roller is fully utilized, and its rotation characteristics enable the pressure roller to flexibly adapt to workpiece surfaces of different shapes and sizes, thereby improving the stability of clamping. Through the design of the centering plate, the insert rod and the wedge block, the clamp can automatically adjust the material to the center position of the workpiece placement block when placing the material, ensuring the straightness of the material. Through the coordinated use of the nut and the threaded column, the clamp can also resist one end of the external workpiece, avoiding the situation where the workpiece retreats due to uneven force during processing, thereby improving the safety of the processing process.
