Abstract

The invention discloses a point circle average diameter detecting mechanism of an internal-tooth-shaped workpiece. The mechanism comprises four sets of identical detecting assemblies that are arrangedaround one same central line, wherein an included angle between every two adjacent sets of detecting assemblies is 90 degrees. Each set of detecting assemblies includes a guiding block with a guidingslot extending in a radial direction of the circumference, a sliding block including a main body part matching the guiding slot, a detecting arm installed at the main body part, a limiting block fixedly connected to the guiding lock, a cylinder for driving the sliding block to slide along the guiding slot, and a displacement sensor. When the sliding block slides to a limit position outwardly, thedetecting arm is abutted against and contact with the limit block. The displacement sensor includes a spring arranged in a shell and a detecting shaft extending from the shell; one end of the detecting shaft is abutted against the spring and the other end is abutted against the outer side of the sliding block to detect radial displacement of the sliding block. With the detecting mechanism, the point circle average diameter of the internal-tooth-shaped workpiece can be detected accurately.

Description

technical field [0001] The invention relates to the technical field of assembly of internally toothed workpieces, in particular to a detection mechanism for the average diameter of the addendum circle of the internally toothed workpiece, which is used to detect the average diameter of the addendum circle of the internally toothed workpiece to assist in the detection of the internally toothed workpiece Assemble. Background technique [0002] A flexible production line in the prior art is used for producing various specifications of products with internally toothed workpieces. The flexible production line is provided with a detection station, which detects whether the average diameter of the addendum circle of the internally toothed workpiece meets the requirements. [0003] At present, the way to detect the average diameter of the addendum circle of the internally toothed workpiece is: the three-coordinate measuring instrument uses a probe to detect the position of 3-6 point...
