The invention discloses an engine valve seat machining spreader and belongs to the field of spreaders. The spreader includes a top plate and a fixing pin, a hook is mounted in the middle of the upperend of the top plate, mounting notches are formed in the left and right ends of the top plate, pin holes are formed in the inner side walls of the mounting notches, and moving lifting columns are mounted in the mounting notches. Lifting grooves are formed in the middles of the lower sides of the moving lifting columns, springs are mounted at the bottom ends in the lifting grooves, sliding groovesare formed in the left and right outer side walls of the moving columns, loosening parts are mounted in the sliding grooves, wedge-shaped blocks are mounted on the left parts of the inner ends of theloosening parts, pressing plates are mounted in the lifting grooves, and pin blocks are fixedly connected with the left and right end walls of the pressing plates. The engine valve seat is supported from the bottom by two carrying plates via the two moving lifting columns, then the pressing plates are pressed downward, so that support plates move downward until a clamping blocks is in contact withthe engine valve seat, a button is rotated manually, the length of screws penetrating through the supporting plates is adjusted, meanwhile the tightening force of clamping the engine valve seat by the clamping block is increased, and the stability of hoisting the engine valve seat can be facilitated.
