Embodiment
For summary of the invention of the present invention, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 and Fig. 2, conventional high rate link lever press displacement transducer system comprises multiple displacement transducers such as large slider displacement sensor 1, small slide block displacement transducer 2, fine setting displacement transducer 3, and each displacement transducer detects a specific work package; Therefore be in installation process, need to lay more cable, during use, failure rate is higher.
Refer to Fig. 3 and Fig. 4, a kind of optimization method of high speed link lever press displacement transducer system, comprises the steps:
Step one, large slider displacement sensor is installed on large slide block, small slide block is installed small slide block displacement transducer;
Step 2, in the process of large slide block movement record store large slider displacement information; In the process of small slide block motion, record stores small slide block displacement information; And above-mentioned large slider displacement information and the storage of small slide block displacement information are preserved;
Step 3, the large slider displacement information collected by synchronization and small slide block displacement information are set up for mapping relations one by one; By above-mentioned large slider displacement information, small slide block displacement information and one by one mapping relations be stored into Programmable Logic Controller;
Step 4, dismounting small slide block displacement transducer, and the large output signal terminal of slider displacement sensor is electrically connected with the signal input terminal of Programmable Logic Controller.
Further: the precision of described large slider displacement sensor is not less than 0.005mm resolution; Large slide block is provided with two stock's displacement transducers that precision is 0.1mm.
Further: described large slider displacement sensor is the displacement transducer of SSI series 25 gray encoding forms of MTS brand.
By the system after the above-mentioned optimization of the present invention, mainly comprise: for detect large slider displacement large slider displacement sensor 1, for receiving the Programmable Logic Controller of large slider displacement sensor 1 Information Monitoring, wherein: connected by connecting rod between the large slide block of described high speed link lever press and small slide block, large slide block movement is driven by connecting rod by the cylinder movement of small slide block, the moving displacement of large slide block and small slide block has the funtcional relationship mapped one by one, but due to the installation of connecting rod and above-mentioned funtcional relationship very complicated, want to show that the position of small slide block is very difficult by the method for mathematical computations by large slide block, like this by installing small slide block displacement transducer additional, generate with the corresponding small slide block displacement of database that is benchmark of large slider displacement by programmable controller PLC in press proper motion, simultaneously because the precision of the large slider displacement sensor selected is very high and higher than the displacement transducer of small slide block, at this moment set up correspondence database with large slide block for benchmark and can ensure display precision, such as when the first displacement chi (large slider displacement sensor 1 and small slide block displacement transducer 2 are preferably displacement chi by this specific embodiment) display position is 800.005MM, second displacement chi display 0.0MM
First displacement chi=800.010MM, second displacement chi=0.0MM
First displacement chi=800.015MM, second displacement chi=0.1MM
Draw the database based on large slide block according to actual conditions successively, this simplifies the second displacement chi, and during press proper motion, the physical location of large slide block is detected by displacement transducer to draw, and the position of small slide block is database by calling generation and draws,
Simultaneously the lower dead point position of link type hydropress is drawn by micro-tensioning system adjustment, and when finely tuning motion, it is exactly the movement of micro-tensioning system that the position that the displacement transducer of large slide block detects is moved, and adjusts the benchmark of database in this process simultaneously.Still can show small slide block position accurately.
