Background

In the key procedures of the existing belt pulley, such as stamping, spinning, machining and the like, a central hole is often used as a machining clamping positioning reference, and if the central hole is used as the reference to detect that the outer contour is not accurate in jumping, the process dimension is unstable, the next procedure machining is directly influenced, and finally the product quality is poor and even the product is scrapped.

For a thin-plate belt pulley (the thickness of a raw material is less than 4MM), due to the structural characteristics, the axial length of a jumping reference hole is less than or equal to 1 material thickness, and if a tapered mandrel is used for detecting the product, clamping is unreliable due to the short guide length of the reference hole, so that the measurement repeatability is poor and the measurement error is large. On one hand, if the problems are to be avoided, the core rods with smaller taper specifications are used for detection, but the number and the types of the core rods with smaller taper are increased due to the tolerance of the inner holes of the products and the difference of the diameters of the inner holes, so that the cost of the detection tool is high, and the management cost is high; on the other hand, if a high-precision measuring device is used for detection, such as a three-coordinate system, the device purchasing cost is high, the requirement on the skills of detection personnel is high, the detection cost is high, the detection frequency is low, and online detection cannot be realized.
