Problems solved by technology

[0002] In the past, the plate-shaped roller used to detect the flatness of the surface of steel, copper, aluminum and other metal plates and strips has an integral structure. The axes of the rollers are evenly distributed, and run through the entire roller body along the axis of the plate-shaped roller. The circular hole for installing the sensor belongs to deep hole processing, which is difficult to process and poor in processing quality. The straightness of the hole and the parallelism of the axes between the holes , hollow cylindricity, and surface quality of the hole cannot be guaranteed; while the processing quality of the circular hole where the sensor is installed has a decisive impact on the detection sensitivity and accuracy of the flatness of the metal plate and strip. With the existing market The flatness requirements of metal plates and strips are getting higher and higher. The plate-shaped rollers with the overall structure in the past can no longer meet the current production and testing requirements of metal plates and strips. It has become an urgent technology in the field of metal plates and strips production and testing technology. obstacle

Abstract

The invention discloses a composite high-precision plate roller which comprises a mandrel, a sleeve and a sensor. The mandrel is a stepped shaft, a plurality of mandrel U-shaped grooves are evenly distributed in the outer diameter of the section, with the largest diameter, of the middle of the mandrel around the axis, the mandrel U-shaped grooves are machined through a forming milling cutter, andthe technical problems of straightness of deep hole machining and axis parallelism between holes in the prior art are solved. The sleeve is in a circular tube shape, the diameter of an inner hole of the sleeve is large, grinding machining or boring machining is adopted for final machining, and the technical problems of cylindricity and hole surface quality of previous deep hole machining are solved. Therefore, the detection sensitivity and accuracy of the composite high-precision plate type roller on the flatness of a metal plate and a strip are greatly improved, the current production detection requirements of the metal plate and the strip are met, and the technical problems in the technical field of production detection of the metal plate and the strip are successfully solved.

Description

technical field [0001] The invention relates to the technical field of detecting the flatness of the surface of steel, copper, aluminum and other metal plates and strips, in particular to a composite high-precision plate shape roller. Background technique [0002] In the past, the plate-shaped roller used to detect the flatness of the surface of steel, copper, aluminum and other metal plates and strips has an integral structure. The axes of the rollers are evenly distributed, and run through the entire roller body along the axis of the plate-shaped roller. The circular hole for installing the sensor belongs to deep hole processing, which is difficult to process and poor in processing quality. The straightness of the hole and the parallelism of the axes between the holes , hollow cylindricity, and surface quality of the hole cannot be guaranteed; while the processing quality of the circular hole where the sensor is installed has a decisive impact on the detection sensitivity ...
