The detector can automatically and precisely detect the size of grinding with discrete surfaces, and the detection precision is +-0.006 mm. The detection range of the detector is wide, the displayable processing allowance is 0.4 mm, the processing overmeasure of actual allowance can reach to 4 mm, and the sensitivity and reach to 0.0005 mm. The utility model can be matched with a feed machine of a common grinding machine tool to realize the closed-loop control of working process and increase the processing precision and the processing efficiency of workpieces.
Description
The utility model belongs to the size on-line measuring device in the mechanical processing process, particularly for the size on-line automatic detection device in the flat surface grinding process.
Size problem on line detection in the process of plane is to reduce unproductive time, improve one of important means of working (machining) efficiency and precision, once carried out a large amount of research both at home and abroad, China Tianjin machine tool plant has developed a kind of mechanical contact measuring apparatus at present, it has only realized the measurement to continuous finished surface, its certainty of measurement reaches ± 0.02mm, therefore the contact of this measurement mechanism can not be realized online measurement of discontinuous surfacing workpiece size owing to falling in the finished surface discontinuities and easily producing misoperation." the flat surface grinding gauging instrument " of the development of external Italian Marposs S.P.A it adopted the oil damping method to prevent that gauge head from falling, realize the online dimensional measurement of discontinuous processing, it is in data acquisition, utilize gauge tap, make workbench every back and forth (or revolution) once, measure data (point), and with the numeric ratio of prior setting, realize the Detection ﹠ Controling of size in the process, this measuring instrument exists the contradiction between oil damping size and the gauge head frequency response, and the sealing leak problem, to making the processing and manufacturing difficulty, range ability is narrow, and cost is higher, adjusts complicated during measurement.
The purpose of this utility model is a kind of checkout gear that can carry out the on-line machining measurement to any discontinuous flat surface grinding processing dimension of design.
The purpose of this utility model realizes with following technical scheme.The electronics system that it mainly is made of mechanical contact formula measurement mechanism and conventional displacement signal treatment system can control system.The structural feature of mechanical contact measurement mechanism is: on a cramp bar that is fixed on the base, be provided with one can lifting on this cramp bar housing, be provided with a fixed axis in this housing, be equipped with on this fork and with the frictional disk of fork Joint, one end of the fork displacement transducer interior with being fixed on housing contacts, and the other end is equipped with contact that contacts with workpiece and the sensor that workpiece is intermittently differentiated.Drive the revolution of frictional disk low speed by the electric control system controls micro machine during work, the contact end of fork is contacted with measured workpiece all the time and keep certain ergometry, when minor variations takes place in the size (diameter) of measured workpiece, displacement appears in contact, its displacement converts thereof into the signal of telecommunication by fork other end displacement transducer and delivers to signal processing system and single-chip microcomputer microcomputer system, show or read detected value, thereby realized online size detection the processing of discontinuous plane.The combination of this signal processing system and microcomputer system has constituted a complete electric-control system, and this electric-control system is SCB-31-II and the SCB-31-III type electric-control system (seeing the circuit diagram of accompanying drawing 3) that Qidong, Jiangsu radio factory produces.
The utility model has the advantages that: owing to adopted the mechanical sensing type structure to cooperate with the appropriate of electric-control system, so it can be accurately to the grinding size online automatic detection on any discontinuous plane, and accuracy of detection height, precision are ± 0.006mm, detection range is wide, can show allowance is 0.4mm, the actual allowance that allows can reach 4mm, sensitivity can reach 0.0005mm, owing to adopted mechanical friction disc type damping structure to replace oil damping in the past, oily leakage and oil damping have been eliminated like this and the gauge head frequency response problem brought.Owing to pass through to the interrupted contact sensor of differentiating of workpiece and the appropriate cooperation of signal processing system, gauge head is risen and fallen automatically, solved gauge head " whereabouts " problem in the past, this device is after adjusting expansion, can match with the feeding machinery of plain grinding lathe and use the closed-loop control that realizes process, thereby improve the machining accuracy and the working (machining) efficiency of workpiece.
