The invention discloses a piston ring groove shape error automatic measuring instrument. The instrument comprises a pedestal, wherein a rotary table and a displacement mechanism installed on the pedestal, the rotary table is used for supporting a piston to be measured, a rotation driver used for driving the rotary table to rotate is installed in the pedestal, and a measurement sensor is installed on the displacement mechanism; the device further comprises an industrial personal computer connected with the displacement mechanism and the measurement sensor, the industrial personal computer controls the displacement mechanism to work according to the model of the piston to be measured so as to drive the measurement sensor to stretch into the ring groove of the piston to be measured, and the measurement sensor transmits measurement data to the industrial personal computer so as to obtain circumferential straightness, radial straightness and the angle of the ring groove. The shape error of the piston ring groove is automatically measured through cooperative use of all the parts, the structure is simple, operation is convenient and fast, a traditional manual detection mode is replaced, measurement efficiency is improved, detection precision is improved, and the piston quality is guaranteed. The invention further provides a piston ring groove shape error measuring method.
Description
technical field [0001] The invention relates to the field of piston processing, in particular to a shape error measuring instrument for piston ring grooves. In addition, the invention also relates to a method for measuring the shape error of the piston ring groove. Background technique [0002] As an important part of various systems, the piston is widely used in various technical fields. The outer circumference of the piston is provided with a ring groove, which is a rectangular groove or a trapezoidal groove. In order to ensure the reliability of the equipment, it is necessary to detect the shape error of the piston. The inspection items of the ring groove include circumferential straightness and radial straightness, and the trapezoidal groove also detects the angle. [0003] Due to the small tolerance range of the piston ring groove, the detection accuracy is extremely high. The current detection method is manual detection through the roundness meter, the detection effi...
