The utility model can replace the relay control system of switch quantity control class machine tool, such as combined machine tool, etc.). The utility model has the advantages of small size, convenient maintenance, high reliability, low cost, simple line, easy design changing and easy function extending.
Description
The utility model relates to a kind of automatic control technology, particularly a kind of electronic control technology of lathe.
At present, to be used for Machine-Tool Control quite general for microcomputer (particularly single card microcomputer).But belong to switching value control class lathe, adopt Control System of Microcomputer as building-block machine, multitool lathe etc., since the systematic comparison complexity, the cost height, and some functions of microcomputer can not fully be used again, it is promoted the use of be restricted.Thereby relay control system is still being used.Relay control system exists that volume is big, reliability is low (limiting because of being subjected to contact endurance), distribution manufacturing expense height, shortcomings such as easy-maintaining, change design inconvenience and expanded function difference.
The purpose of this utility model is to replace switching value control class lathe with conditional stepping type programmable machine bed controller, the traditional relay control system that is adopted as building-block machine, multitool lathe etc., thus overcome the deficiency of relay control system.
Fig. 1 is a structural representation of the present utility model.This controller mainly is made of guidance panel 1, control circuit board 2 and frame 3.Clearly total/release-push K is housed on the guidance panel 1

720 four road rotary-step conditions of input output to the CP end of counter 7 by the work step order by output terminal Z singly, under the effect of these rotary-step condition count pulses, make counter make plus coujnt continuously, turn back to zero after reaching maximal value, begin again.During 16 steps, can after finishing work step, automatically return to original state as the work step less than by an automatic return circuit in the controller.Therefore the program in the memory can be carried out repeatedly, and promptly each process can be carried out repeatedly.20 four road rotary-step conditions inputs derives from the lathe 24 buttons and travel switch, and the every action under selected situation of each button and travel switch once can be sent into a count pulse.
More than be stated as groundwork process of the present utility model.Below how each button, switch on the guidance panel are implemented function control explanation one by one.
Counter 7 has four output terminals among Fig. 2, can specify 16 addresses, i.e. 16 steps.And memory 8,9,10 every 11 bit address line input ends, eight bit data line output terminal are arranged, so every but 2,048 eight bit location storage informations are arranged.If going on foot with 16 is a cycling element, then can deposit 128 kinds of circulations in the memory.Consider the convenience that the operator uses, adopt decimal system dial.Therefore also to consider former road withdrawing function in addition, with the A of three memories
4～A
7Four address wire input ends meet the position of dial BM, A respectively
8, A
9End meets ten of BM respectively, can only deposit 40 kinds of working cycle and corresponding 40 kinds of former road withdrawings circulations in the memory since like this, can select execution arbitrarily by dial BM.Generally speaking, 40 kinds of working cycle can satisfy the needs that various switching values are controlled the various processing of class lathe; When in particular cases 40 kinds of working cycle can not satisfy processing request, can take the various process that controlled lathe will be finished are depended in the in fact selection of integrated circuit and sheet number thereof fully.Carry out briefly bright below on this question.
Among Fig. 2, multi-channel data selector switch 4,5,6 models are MC14512, in fact the model of each data selector, its number of channels and be in parallel or only used a slice by several data selectors depend on the quantity of each button and switch on the lathe of importing rotary-step condition.Can preset up/down binary counter 7 models is MC14516, in fact can preset up/down binary counter and adopt what model, how many figure places and only be in series with a slice or by several, depends on the work step quantity of various process.Programmable read- only memory 8,9,10 models are 2716EPROM, in fact the programmable read-only memory adopts what model, every that how many capacity of how many figure places are arranged and is in parallel by a slice or several, depends on that every kind of lathe has how many kinds of fabrication cycles and each work step will drive the power on quantity of magnet valve of lathe.It is MC1413 that driving amplifier 11,12,13 adopts high-voltage large current seven inverting amplifiers, model, in fact driving amplifier adopts any model, is in parallel with a slice or several, depends on that the data level that programmable read-only memory data line output terminal can be exported is amplified to can drive relay and remove to drive all solenoid valves on the lathe.
Fig. 3 is embodiment of the present utility model, and its core and Fig. 2 are identical.That different is the input end X of multi-channel data selector switch 4,5,6

4End) joins.Photoelectric isolating circuit and relay J
1～J
16Make core of the present utility model be in " floating empty " state, promptly its internal signal and outside forceful electric power signal do not have electric getting in touch, so antijamming capability is strong, can be in the more workshop condition of interference source operate as normal.Because the coil of timing relay SJ and the Y of driving amplifier 13
4End joins, and its contact is by the input end X of a photoelectric isolating circuit and multi-channel data selector switch 6
7Join, this contact is equivalent to a switch input on the lathe, has then formed a delay circuit.A certain work step need be delayed time and be added man-hour in lathe cyclic process process, makes the data line output terminal D of this work step by programmable read-only memory 10
4The data of output are " 1 ", then the Y of driving amplifier 13
4End is for high level, and it is electric that time relay sj is got, and as the input rotary-step condition, have only its contact delay time arrive and during the closing of contact, could change next work step, thereby realize delay function this moment.When one tunnel time-delay can not be satisfied the machine tooling requirement, as long as it is just passable to increase timing relay.But increased after the delay circuit, the way of controller input, output has all been reduced accordingly.In this example because of being connected to No. one delay circuit, thereby drive 16 solenoid valves on the lathe again after having only 20 three road rotary-step conditions input and ten six tunnel to export to succeed electrical equipment.In order to keep former input, output quantity, can increase corresponding integrated circuit as aforementioned, just do not given unnecessary details here.Among Fig. 3 at emitter resistance 1R

24The incoming level monitoring circuit that is in series can make the operator understand the ruuning situation of this controller conveniently, intuitively.
By the above, because the utility model only adopts a small amount of integrated circuit, thereby it is simple, reliable and stable to have a circuit, processing ease, and easy to maintenance, volume is little, low cost and other advantages. Because variable volume of program in the programmable read-only memory, various integrated circuit connection in series-parallel are used extremely simple, thereby change designs and expanded function is very convenient, easy. The utility model not only is applicable to various switch amount control class lathes, such as building-block machine, multitool lathe, also can be applied to other similar process control occasions.
