Abstract
The utility model discloses a ship crank shaft and crank space automatic measuring system, comprising a computer, a displayer, a keyboard and a length measuring instrument for measuring the space between the crank shaft and the crank; wherein, the displayer and the keyboard are connected with the computer; and the length measuring instrument is connected with a wireless signal transmitting circuit; and a wireless signal receiving circuit connected with the computer is arranged corresponding to the wireless signal transmitting circuit. The automatic measuring system solves the problem that the space between the crank shaft and the crank is difficult to be measured by manually; the automatic measuring system not only realizes real time automatic measurement but also realizes multi-azimuth measurement; the measured data is precise; and the computer can carry out complicated calculation to replace the manual conversion, which greatly saves time and labor and greatly improves the processing and positioning accuracy and the production efficiency of the crank shaft of the ship.
Description
Technical field:
The utility model belongs to the Automation in Mechanical Working measurement mechanism, especially a kind of in the process of taking back processing assembly type crank axle for vessel on the special-purpose bent axle lathe that changes centre frame, but real-time automatic measuring crankshaft crank spacing, accurate, time saving and energy saving, the safe and reliable crank axle for vessel crank spacing automatic monitoring system of numerical value.
Background technology:
At present, all be to adopt to take back special-purpose bent axle lathe (as the heavy bent axle whirling of numerical control machining center) the processing semi-built-up crank axle for vessel that changes centre frame mostly.Because crank axle for vessel is supported and the location by several centre frames on crankshaft toothed wheel, the extension elongation of each centre frame pillar can directly influence the positioning accuracy of each trunnion of bent axle, and then influence the axiality of main bearing journal, therefore before processing, all need bent axle is accurately located.Existing localization method is that the operator by crankshaft toothed wheel operates rotary crankshaft on one side, on one side with dial gauge measure between two crank arms of each crank throw turn span from, observe the variation of bent axle each crank spacing in a swing circle, judge the axiality of each trunnion of bent axle with this, the bent axle that has coaxiality error is then carried out error correction by the extension elongation of adjusting the centre frame pillar.In order to protect the personal safety of survey crew, when practical operation, do not allow under the bent axle rotary state, to carry out manual measurement, this just need carry out segmentation, gradation measures, and promptly measuring after the secondary data turns an angle bent axle measures next time again ...This manual measurement mode is the degree of danger height not only, but also to expend great amount of manpower and time, because measured value is a sampled measurements, exist human error simultaneously, have a strong impact on the positioning accuracy and the crudy of bent axle, be unfavorable for very much on-the-spot location, processing.
Summary of the invention:
The utility model is in order to solve the above-mentioned technical problem of existing in prior technology, but a kind of real-time automatic measuring crankshaft crank spacing, accurate, time saving and energy saving, the safe and reliable crank axle for vessel crank spacing automatic monitoring system of numerical value are provided.
Technical solution of the present utility model is: a kind of crank axle for vessel crank spacing automatic measurement system, the display, the keyboard that computer are arranged and join with computer, be provided with the length measuring instrument that is used to measure the crankshaft crank spacing, length measuring instrument and wireless signal transmission circuit join; The corresponding wireless signal receiving circuit that joins with computer that is provided with wireless signal transmission circuit.
Also be provided with pressure sensor, pressure sensor joins by signal processing circuit A and computer; Be provided with angular encoder, angular encoder joins by interpolation digitizer, signal processing circuit B and computer.
The utility model has solved the problem of crankshaft crank spacing manual measurement difficulty, not only realized real-time automatic measuring, and realized multi-faceted measurement, measurement data is accurate, also can carry out complicated calculations simultaneously by computer, replace the manual conversion, save plenty of time and manpower, improved the setting accuracy on work and the Production of Crankshaft efficient of crank axle for vessel greatly.Particularly be provided with pressure sensor and angular encoder etc., can detect the angle of crankshaft rotating and the pressure that crank shaft supporter bears simultaneously, by computer calculating changing value is shown, assist operator is analyzed the bent axle coaxiality error, avoid adding big stress deformation takes place man-hour, cause trueness error.
Description of drawings:
Fig. 1 is the schematic block circuit diagram of the utility model embodiment.
The specific embodiment:
As shown in Figure 1: a kind of crank axle for vessel crank spacing automatic measurement system, the display, the keyboard that computer (industrial computer) are arranged and join with computer, be provided with the length measuring instrument that is used to measure the crankshaft crank spacing, length measuring instrument and wireless signal transmission circuit join; The corresponding wireless signal receiving circuit that joins with computer that is provided with wireless signal transmission circuit.
Length measuring instrument can adopt the incremental length gauge of external import, and each turns the extended distance of crotch to measure bent axle, and bent axle is a rotation status during owing to measurement, so adopt the mode of wirelessly transmitting data.The length measuring instrument, wireless signal transmission circuit, the power module that utilize Magnetic gauge stand and matched bracket that length gauge and measurement module are formed all are fixed on bent axle and turn the crotch place, rotate with bent axle, realize measuring in real time.The data-signal that records is changed data mode by wireless signal transmission circuit, transfer to wireless signal receiving circuit (WLAN router) in the wireless ethernet mode then, wireless signal receiving circuit is furnished with respective antenna and is used to receive data-signal, be connected with the computer Ethernet interface again simultaneously, can handle calculating and demonstration through the special-purpose software that is installed in the computer to data then with transfer of data to computer.Each turns the variation of crotch extended distance data the bent axle that the operator can show on the supervision industrial computer in the operating crank rotation, analyze the coaxiality error of bent axle, then the pillar height of crank shaft supporter is adjusted, progressively dwindled the bent axle coaxiality error.Whole system adopts bus and the wireless mode that combines, and measures accurately, and is very convenient.
The utility model also is provided with pressure sensor simultaneously except each of measurement bent axle turns the extended distance of crotch, and pressure sensor joins by signal processing circuit A and computer; Be provided with angular encoder, angular encoder joins by interpolation digitizer, signal processing circuit B and computer, can detect the angle of crankshaft rotating and the pressure that crank shaft supporter bears simultaneously.Angular encoder is contained on the machine tool chief axis and can measures the anglec of rotation, pressure sensor is installed in and measures the pressure that bracing frame bears in the bracing frame Hydraulic Station, pressure data and angle-data are by signal processing circuit A, B, amplify, transfer to computer after the processing such as analog-to-digital conversion, various data are handled calculated and show through being installed in software in the computer then.The pressure that crankshaft rotating angle that the operator can show on supervisory computer in the operating crank rotation and bracing frame are born changes assistant analysis bent axle coaxiality error.
The interpolation digitizer, in order to guarantee that the measuring-signal that machine tool numerical control system also can collect simultaneously this encoder is provided with, it can be enlarged into the data-signal of encoder output the multi-form data-signal of two-way for digital control system and measuring system image data.
