Problems solved by technology
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, the 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 system and method for the Rockwell hardness block verification device

The invention discloses an automatic sampling and calibration system and method of a Rockwell hardness block testing device, belonging to the field of hardness measurement. The invention includes a system master control device, a robot base, a robot, a sample placement platform, a feeding tray, a substandard product tray, a measurement compensation mechanism, a clamping and measuring device, a measuring platform, and a hardness measuring device. The present invention combines the Rockwell hardness standard machine to freely set the calibration number of hardness blocks and the calibration trajectory scheme; automatically grab the hardness blocks in the material loading system and place them on the measurement compensation mechanism; Block position compensation; the handling handle transports the hardness block to the measuring platform; the indenter presses the hardness block under the action of the test force to produce indentation and measurement; the handling handle moves the hardness block under the control of the master control device to achieve position change and perform pressing and measurement ; After the calibration of a single hardness block is completed, the manipulator grabs the hardness block from the workbench to the loading position to realize automatic sampling and calibration of multiple 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...
