Automatic sample introduction and calibration system and method for Rockwell hardness block calibration device

Abstract

The invention discloses an automatic sample introduction and calibration system and an automatic sample introduction and calibration method for a Rockwell hardness block calibration device, which belong to the field of hardness measurement. The automatic sample introduction and calibration system comprises a system master control device, a robot base, a robot, a sample placing table, a feeding tray, an unqualified product tray, a measurement compensation mechanism, a clamping measurement device, a measurement platform and a hardness measurement device. The automatic sample introduction and calibration system combines a Rockwell hardness standard machine, and sets a hardness block calibration number and a calibration trajectory scheme freely; a hardness block in a material loading system isautomatically grabbed and placed on the measurement compensation mechanism; the clamping measurement device measures the size of the hardness block and compensates for the position of the hardness block; a carrying gripper carries the hardness block to the measurement platform; a pressure head presses the hardness block under the action of a test force to generate an indentation and measures theindentation; the carrying gripper carries the hardness block under the control of the master control device to realize position change and performs pressing and measurement; and after the single hardness block is calibrated, a mechanical arm grabs the hardness block away from a workbench to a material loading position, thereby realizing automatic sample introduction and calibration of a pluralityof hardness blocks.

Description

technical field [0001] The invention belongs to the field of hardness measurement, in particular to an automatic sampling and calibration system and method of a Rockwell hardness block testing device. Background technique [0002] Rockwell hardness is an important index to evaluate the mechanical performance parameters of materials. It plays a very important role in the process of mechanical design, manufacturing, production and maintenance. Almost all metal products must be tested for Rockwell hardness. However, at present, most of the Rockwell hardness standard machines in my country adopt the static weight loading structure, which has a large structure and low automation. During the calibration process of Rockwell hardness blocks, the replacement of different hardness blocks and The transformation of different indentation points is all done manually, which seriously affects the efficiency of measurement work. At present, there is no automatic sampling and calibration syst...
