Description

technical field [0001] The invention relates to a measuring machine device, in particular to a ball screw transmission connection device in the measuring machine. Background technique [0002] The high-precision three-coordinate measuring machine driven by ball screw can realize high-speed and accurate positioning of the moving parts of the measuring machine. There are usually two options for ball screw installation: 1. One end is fixed and the other end moves; 2. Both ends are fixed. [0003] Since the beam is made of granite, which is different from the material of the ball screw, the expansion coefficient is also different, so the two are prone to stress during the temperature change. Therefore, the measuring machine often adopts option 1. However, in Scheme 1, one end of the lead screw moves and is affected by gravity to produce deflection. During the rotation of the lead screw, centrifugal force and deflection act simultaneously, and the lead screw will produce a larg...
