Description

Technical Field

[0001] This utility model relates to the field of roughness measurement technology, and in particular to a roughness measuring device for holes made of carbon steel. Background Technology

[0002] Carbon steel is an iron-carbon alloy with a carbon content typically ranging from 0.05% to 2.1%. Based on its carbon content, carbon steel can be classified into low-carbon steel, medium-carbon steel, and high-carbon steel, each type having different performance characteristics and application areas. Due to its excellent mechanical properties, cost-effectiveness, and wide applicability, carbon steel is widely used in various industries such as industrial manufacturing, construction, automotive, and machinery. With increasing demands for product performance, the surface roughness requirements for internal holes in parts are becoming increasingly stringent, thus necessitating the measurement of the surface roughness within the holes.

[0003] However, in the existing technology, when measuring the roughness of holes in carbon steel, the workpiece is usually fixed directly to the measuring device and the measuring head is then embedded in the hole. However, the fixed workpiece makes it difficult for the measuring probe to measure different positions inside the hole, thus reducing the accuracy of the measurement. Moreover, workpieces of different sizes are not easy to move after being fixed, so the measuring probe needs to be adjusted manually, which is time-consuming and laborious, thus reducing the measurement effect.

[0035] In this embodiment, the carbon steel workpiece to be measured is embedded inside the U-shaped plate 108. At the same time, two electric push rods 109 are activated to drive the clamping plates 110 to move relative to each other, clamping and fixing the workpiece so that it is more stably embedded inside the U-shaped plate 108. Protective pads 119 are fixedly installed on the opposite surfaces of the two clamping plates 110, which not only improves friction and prevents the workpiece from sliding, but also protects the workpiece. The servo motor 117 is activated to drive the threaded rod 103 to rotate. The threaded rod 103 drives the measuring probe 115 to move up and down and adjust according to the size of the workpiece through the slider 113 and the T-shaped plate 114.
