Turning dynamometer connecting base suitable for different lathe saddles

The invention discloses a turning dynamometer connecting base suitable for different lathe saddles. The turning dynamometer connecting base is simple in structure, convenient to use, practical and high in positioning precision. The turning dynamometer connecting base comprises two supporting plates, a vertical plate and a connecting base plate, wherein a plurality of evenly distributed threaded holes are formed in the top surface of the vertical plate, one end of each supporting plate is perpendicularly and movably connected with the upper top surface of the vertical plate through first screws penetrating through the threaded holes, and a stepped surface is arranged on the outer side of the vertical plate; the top surface of the connecting base plate abuts against the stepped surface of the vertical plate, the side surface of the connecting base plate is perpendicularly and fixedly connected with the stepped surface of the vertical plate partially through second screws, and a plurality of bolt holes used for being connected with a turning dynamometer are formed in the upper surface of the connecting base plate. According to the turning dynamometer connecting base, the connecting base can be installed on the lathe saddles in different sizes by adjusting the distance between the two supporting plates, installation of different parts is conducted at the same time, experiment labor intensity is low, and experiment preparation time is short.
