Abstract

The invention discloses ball screw efficiency test equipment which comprises a bottom plate and further comprises a screw rod tension and compression device, a screw rod loading device, a screw rod fixing tailstock, a nut fixing structure, a nut rotation driving mechanism, a displacement test mechanism and a control device, the screw rod tension and compression device and the screw rod fixing tailstock are slidably arranged on the bottom plate; the lead screw loading device, the nut rotation driving mechanism and the displacement test mechanism are installed on the bottom plate, and the lead screw loading device carries out axial loading on a ball screw to be tested through the lead screw tension and compression device. The nut fixing structure is installed on the nut of a ball screw to be tested during testing, the nut rotation driving mechanism drives the nut to rotate through the nut fixing structure, and the displacement test mechanism tests the displacement of the screw rod in the ball screw to be tested through the screw rod tension and compression device. The invention further discloses a ball screw efficiency test method. The accuracy of the efficiency of the ball screw during forward and reverse rotation is effectively ensured through the load of push and pull force on the screw rod.

Description

technical field [0001] The invention relates to the technical field of ball screw testing, in particular to a ball screw efficiency testing device and testing method. Background technique [0002] Since the current ball screw test equipment cannot ensure that the loading end and the rotating end are absolutely 100% concentric during the manufacturing process, and there are certain errors in the slider during the operation of the guide rail, so if we use rigid connection when loading , the efficiency of some parts will be lost to some extent, and the efficiency of the tested parts should be low. [0003] For this reason, the applicant submitted to the State Intellectual Property Office on December 25, 2019 an invention patent application titled "An Improved Ball Screw Efficiency Test Tool" with the application publication number CN111060311A, which has now been published. An improved ball screw efficiency test fixture in this patent application includes a bottom plate, a bas...
