Abstract

The invention discloses a shaft part bounce detection mechanism and a detection method capable of automatically eliminating spindle errors. Two supporting mechanisms are fixed to a machine base through screws, and a workpiece is placed on the two supporting mechanisms. Driving and driven side clamping driving components are located on the left side and the right side of the workpiece correspondingly and fixed to the machine base; the driving and driven side clamping driving components are pushed out and clamped at the two ends of the workpiece through live centers, so that the workpiece is clamped and driven to rotate around the axis of the workpiece to do rotary motion; through pushing out of clamping air cylinders, the live centers clamp the workpiece, and the servo motor drives the centers to enable the workpiece to do rotary motion around the axis of the workpiece; and the bounce detection mechanism is installed beside the workpiece and detects surface bounce of the workpiece in the rotating process. According to the invention, the rotation run-out detection precision of shaft parts is improved; and on the premise that the production efficiency of equipment is not reduced and the detection precision is not sacrificed, the requirements of an equipment tool clamp and the production and use cost are reduced.

Description

technical field [0001] The invention relates to a rotation detection mechanism and detection method of shaft parts, in particular to a mechanical structure and a detection method for eliminating the influence of tip / spindle beating on the test during the detection process. Background technique [0002] Shaft parts have runout requirements during assembly with other parts. Shaft parts generally need to go through rough turning, finishing turning, grinding and other steps. These process steps also have runout requirements for the parts to be processed. Straightening equipment is an automatic equipment that automatically straightens shaft parts to make their runout meet the technical requirements. The general action flow of the straightening equipment is to detect the rotary runout of the workpiece, and then perform pressure cold / flame heat straightening, and repeat the above steps until the final re-inspection meets the qualified requirements. [0003] Runout detection is a ...
