Description
Technical field
The utility model relates to test macro, refers in particular to a kind of system that marine anchor chain flash welding welding process is carried out COMPUTER DETECTION and analysis of being used for.
Background technology
Flash welding is the key link of producing anchor chain with welding method, but the flash welding welding gear on the anchor chain production line is made up of workbench, heating power supply and the corresponding electrical control circuit of the translation of anchor chain stationary installation, and the flash welding welding process comprises preheating, flash welding and top three phases.Facts have proved that the electric current in the flash welding welding process and the situation of change of position are very big to the welding quality influence.On the anchor chain production line and no current, location detecting apparatus, parameters rule of thumb is provided with by operating personnel in the past, and the quality problems of existence also in the end could expose during tensile test, and the anchor chain difficult quality is controlled.Therefore in anchor chain flash welding welding process, be a crucial technological process to the tip displacement of anchor chain and the measurement of welding current.In order to improve tip displacement and welding current measuring reliability, it is very necessary adopting COMPUTER DETECTION.Above-mentioned technological parameter is gathered, stored and analyzes, choose best welding condition,, guarantee that welding quality has crucial meaning to improve welding productivity.
Summary of the invention
Technical problem to be solved in the utility model provides the computer detection system that the flash welding welding process important technical parameter simple, easy to operate, that operational reliability is high was installed and debugged to a cover.
This parameter test system adopts following technical scheme:
The utility model comprises industrial computer, A/D modular converter and signal processing module, and wherein electric current, position transducer link to each other with signal processing module, link to each other with industrial computer through the A/D modular converter again.The flash welding technological parameter is behind spot sampling, and signal is delivered to the signal transformation processing module, and this module is converted into the voltage signal of standard after with the technological parameter signal Processing.All technological parameter signals are delivered to the A/D conversion module and are changed to digital signal and deliver to computing machine after change is sent.
Advantage of the present invention is the instantaneous value of all technological parameters of screen display when gathering, and shows the change curve of technological parameter simultaneously.Software can write down all technological parameters, and the process parameter value of playback technological parameter curve and certain time as requested, with convenient management, simultaneously the quality of product is analyzed.Software can be numbered every anchor chain and each cable link, thereby can understand the welding condition of each cable link, to realize the quality control of anchor chain.
Description of drawings
Fig. 1 is the one-piece construction block diagram of the utility model embodiment.
Embodiment
As shown in Figure 1, among the embodiment of the present utility model, industrial computer adopts and grinds magnificent PC-610 industrial control computer.The A/D modular converter adopts the signal transmission of grinding between magnificent PCL-818HD card realization computing machine and a plurality of message processing module.Because sample frequency is higher, select the PCL-818HD data collecting card that grinds China for use.Grinding magnificent PCL-818HD is high-speed data acquisition card, and can guarantee all has 100kHz sampling rate and slewing rate in all gains (* 1,2,4 or 8, able to programme) and input range.It has FIFO (first in first out) impact damper of a 1K word, to obtain more performance under faster data transmission and the Windows.As one of PCL-818 series, this card provides 5 the most frequently used measurements and control function: 12 A/D conversions, D/A conversion, 16 digital quantity inputs and 16 digital quantity outputs, can programme automatic passage/gain scan of band DMA, counter/timer etc. to the gain of each passage.
In order correctly to write down tip displacement and flash welding welding current, at first will be from the position signalling of welding equipment and the input end that current signal is received the unit signal processing module, by signal processing module position signalling and current signal are handled, above-mentioned two signals are converted into the voltage signal of the 0-5V of standard; This voltage signal is directly inputted to the A/D end of PCL-818 template, carries out the A/D conversion under the control of computing machine, and analog signals is converted to digital quantity signal; After signal enters computing machine, under the control of software, carry out the collection of signal, demonstration, storage, playback, analysis and the printing of technological parameter.
Be the beginning and the end of the reference record of energy CONTROL PROCESS, realize the synchronous of welding process and curve record, in computer detection system, gathered the switching value signal that each machine bond pads begins and finishes, guaranteed the synchronous of welding and record by the I/O mouth.
To signal processing module, it will handle the two-way analog signals.One road analog signals is a position signalling, and it is the d. c. voltage signal of 0-10V, and this signal becomes the normal voltage signal of 0-5V after the amplification of two-stage voltage amplifier circuit and Filtering Processing.Another road analog signals is a current signal, it is the AC signal of 0-20V, and this signal carries out the effective value conversion by AD536 after the one-level voltage amplifier circuit amplifies, again this effective value is carried out primary voltage and amplify, make this current signal be converted into the normal voltage signal of 0-5V.
In the flash welding welding process, welding current will produce stronger undesired signal.In order to improve the reliability of acquired signal, in software, adopted the method for software filtering, the method that has adopted medium filtering and average value filtering to combine during filtering improves the validity of signal greatly.
