In order to solve the above technical problems, a technical solution adopted by the utility model is to provide a platform moving mechanism, including a lifting platform, a vertical guide rod, a horizontal rack, a horizontal transmission shaft, a servo motor, a leveling rack, and a lifting hydraulic cylinder and a hydraulic pump; the hydraulic pump is connected to the lifting hydraulic cylinder through a hydraulic pipe; the lifting hydraulic cylinder drives the lifting platform to move along the vertical guide rod; the servo motor drives the lifting platform to move along the vertical guide rod through the horizontal transmission shaft. Move along the plane of the horizontal rack; the leveling rack is arranged in parallel with the vertical guide rod, and the leveling rack adjusts the lifting platform horizontally.

Preferably, the horizontal rack is fixed on the bottom surface of the lifting platform; the horizontal rack is engaged with the horizontal transmission shaft for transmission; the bottom surface of the lifting platform is also equipped with a horizontal guide rail; the horizontal guide rail is It is fixed on the base of the lower side of the lifting table; the horizontal transmission shaft and the servo motor are fixed on the base; the edge of the lifting table is also provided with a rotating pin for positioning; the lower mold base is placed on the lifting table .

Preferably, the leveling rack is vertically arranged, and a leveling gear matched with the leveling rack is provided on the lifting platform; the lifting platform is lifted and lowered along the vertical guide rod, and the leveling The gear rack is engaged with the leveling gear to maintain the horizontal angle of the lifting platform.

The beneficial effect of the utility model is: to provide a platform moving mechanism, so that the vibration friction welding machine can effectively control the welding process of the relative workpiece in the tight mold to make a circular track in the work, and through the processing of the precision linear slide rail The mold reduces the upper and lower wrong molds of the finished product.
