Abstract

The invention discloses a device special for detecting radial runout of a long-axis workpiece and a using method thereof. The device comprises a workbench, a measuring mechanism, a pressing mechanism,a roller driving conduction mechanism and a driving mechanism. The measuring mechanism is used for detecting radial runout of a workpiece; the roller driving conduction mechanism is used for bearingand rotationally driving the workpiece; the pressing mechanism is matched with the roller driving conduction mechanism, is used for applying radial pressing force to the workpiece and can move along with the workpiece; the driving mechanism is connected with the roller driving conduction mechanism and used for providing driving force for the roller driving conduction mechanism. The device is simple in structure and convenient to use, the rotary torque of a motor can be converted into synchronous rotation of a driving wheel; the driving wheel and the workpiece are externally tangent, matched and rubbed to drive the workpiece to rotate to achieve bearing and driving of the workpiece, meanwhile, a floating pressing function is achieved, the workpiece is in a free state all the time in the rotating process, introduction of gross errors is avoided, and pressing, bearing and driving of the workpiece to be detected are achieved.

Description

technical field [0001] The invention relates to the technical field of mechanical product detection, in particular to a device specially used for detecting radial runout of long-axis workpieces and a method for using the same. Background technique [0002] In mechanical processing, long-axis or pipe-type workpieces are generally processed by turning. The radial runout of the non-clamping end is often out of tolerance, which seriously affects the quality of processing. Therefore, it is urgent to detect and control such workpieces. Processing quality. [0003] For the detection of such workpieces, especially the detection of workpieces whose outer circle is used as a reference, it is usually necessary to position the workpiece and then perform rotation detection on the other end by clamping the processing reference end. The clamping mechanism must have the function of driving rotation, and its own The runout should be as small as possible to avoid gross errors; the positionin...
