Adjustable sheet metal machining clamp

The utility model discloses an adjustable sheet metal machining clamp which comprises a clamp table, a horizontal clamping assembly and a vertical pressing assembly, and the horizontal clamping assembly and the vertical pressing assembly are arranged on the upper surface of the clamp table at intervals. Wherein the vertical pressing assembly comprises a threaded column, a sliding block, a pressing block, an adjusting piece, a fixing column and an elastic assembly, and the threaded column is vertically arranged on the clamp table. The device overcomes the defects that when the device clamps some small sheet metal parts, the length of the sheet metal parts still needs to be fixed firstly, then the width of the sheet metal parts needs to be fixed, the small sheet metal parts can be fixed only through slight pressure, and the machining efficiency is greatly reduced through the fixing mode of the device. According to the adjustable sheet metal machining clamp, the small sheet metal parts can be clamped, and the sm
