Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, and in particular relates to a device for detecting an evenly distributed spiral groove on an outer circle. Background Technology

[0002] Machining refers to the production process that uses mechanical energy to change the shape, size, relative position, and physical properties of a blank through processes such as cutting, forging, stamping, and welding, making it a qualified part that meets the requirements of the design drawings. To ensure that the machined workpiece meets the technical requirements specified in the drawings, various testing devices are usually used for inspection.

However, for some workpieces that require the machining of trisected inclined spiral grooves on their outer cylindrical surface during machining, traditional inspection devices such as calipers and CMMs suffer from poor accessibility, positioning difficulties, and insufficient measurement accuracy due to the specific inclination angle of the spiral grooves. This makes it difficult to effectively and accurately inspect the geometric parameters of the spiral grooves.
