| 6.2.3 Mechatronic installation for oil thread
inspection assortment of «Micron-2» The developer and manufacturer of a thread testing machine of the oil assortment is the company «InSys Ltd.» (Figure 6.8). The unit is designed to automate the control of external and internal threads of the oil assortment in shop conditions. Automation of thread control on pipe bases provides a significant increase in reliability and reduction in rejection during drilling and overhaul of wells. Figure 6.8 – Mechatronic control of oil threads assortment of «Micron-2» The installation includes a measuring unit with a removable periscopic nozzle and a control unit based on an industrial computer. Stationary and portable versions are possible. The main advantages of the mechatronic installation «Micron-2»: 261 • universality of the installation for monitoring various types of internal and external threads; • non-contact measurement method and full replacement of manual control with calibers; • 100% control of each pipe or coupling directly on the production or repair line; • control of all thread parameters according to GOST, high accuracy and repeatability of results; • possibility of measuring the wall thickness under the thread and the internal chamfer; • high reliability, absence of special requirements for maintenance personnel; • absence of special requirements for the basing of pipes at the control position; • small size and weight; • saving measurement results in the database and displaying them as graphic and text protocols with the ability to print; • connection of the plant with the production control system for the certification of pipes. The principle of operation is based on conoscopic profilometry, i.e. non- contact measurement of the thread geometry by laser scanning of a given num- ber of sections (Fig. 6.9) Figure 6.9 – Scheme of the mechatronic installation: 1 – linear motor; 2 – rotation drive of the pickup nozzle; 3 – laser micrometer; 4 – laser beam; 5 – controlled product. The specialized software uses the obtained data for differentiated element- by-element control of individual thread parameters. By results of measurements automatically conforms of the thread to the requirements of GOST and its suitability for subsequent application is determined. The installation can work either autonomously or as part of ACS of production with the output of the 262 obtained measurement results and service signals in digital form. The main controlled parameters are: pitch and thread length, profile height, profile side angle, vertex rounding radius and profile troughs, taper, diameters and thread length, wall thickness under the thread. жүктеу/скачать 11,25 Mb.
