Key Techniques Of Measurement Center Based On Pneumatic Measuring

Pneumatic measurement since it has high measurement precision, measurement process is stable, can realize the non-contact measurement and other characteristics, widely used in industrial field on mass production or production line. When the workpiece is measured in traditional gas measurement instruments more than adopts workers manual measurement method, the intensity of labor is big, the production efficiency is low, already cannot adapt to the current industrial demand for flexible automation measurement on site.With the development of the industrial robot technology, industrial robot control system and the work precision have also meet the requirements of most industrial field.Combining the industrial robot technology and pneumatic measurement technology, implementation of workpiece flexible automation pneumatic measurement is imminent.However, because of today’s pneumatic measurement instrument on the measuring gap when the workpiece is measured in requirements, in the use of mechanical automation measured workpiece easy jam at the time of pneumatic measuring in the measuring device.This paper mainly studies the key technology of measurement based on the pneumatic measurement technology,combine the mechanical and pneumatic measurement system module, realize the industrial field of flexible automation pneumatic measurement.Design a new type of pneumatic measuring device at the same time, can not only make the workpiece to be measured in the process of measuring smoothly into the measuring device, eliminate the phenomenon of artifact jam easily in the measuring device, pneumatic measuring device is combined with mechanical hand to realize the automatic mechanical measurements, and uses the girth structure instead of the traditional aerodynamic diameter measuring device nozzle baffle mechanism structure, make the measurement more stable and reliable.This paper firstly on the relevant theories of industrial robot technology and pneumatic measuring technology in-depth analysis and study,researched onthe structure features and precision of rectangular coordinate robot and multi-joint robot, as well as the present industrial field assembly automatic line of flexible structure system, based on the principle of the pneumatic measurement technology and the study of the characteristics of the pneumatic measurement instrument, and puts forward a new type of pneumatic measuring device.Then paper on account ofaerodynamic diameter measurement, design the structure of the manipulator with pneumatic measuring function, driven by industrial robot pneumatic measuring manipulator to realize automatic detection of workpiece to be measured.Experiments prove that the robotic arm with pneumatic measuring to realize automatic measurement ofthe workpiece, must adopt flexible structure, can prevent artifact jam in the pneumatic measuring device.Behind, to the need of pneumatic measuring manipulator for flexible structure, the paper puts forward a new type of pneumatic diameter measuring device and an aerodynamic diameter measuring device, measuring device with double cone and spherical structure respectively, and puts forward the structure of the girth, solve the traditional pneumatic measurement device easily when combined with industrial robots using automated measurements and workpiece to be measured easily stuck, mechanical flexible automation pneumatic measurement is realized.Finally aerodynamic diameter measuring device, for example, through to the aerodynamic diameter volume device the workpiece to be measured in the measurement of force in the process of the analysis and calculation, verify the feasibility of the new pneumatic measurement device.
