Detailed description of the invention
Below in conjunction with the Figure of description provided, description is made to preferred embodiment of the present utility model.
As shown in Figures 1 to 4, a kind of Contact Pointer Type Tool is provided in the present embodiment, for detecting the cutter 11 of lathe 1, lathe 1 comprises the tool 12 for fixed product 2, cutter 11 pairs of products 2 are processed, cutter 11 break detecting device comprises control module 13 and relay 14, cutter 11, product 2, the control system of tool 12 and relay 14 and control module 13 measure loop in series, relay 14 by control system and control module 13 backfeed loop in series, when cutter 11 fractures and causes measure loop to disconnect, backfeed loop disconnects shuts down to make control module 13 control lathe 1.
Relay 14 adopts electromagnetic relay 14, and the control system of relay 14 mainly comprises the wire etc. of coil and necessity, and mainly comprised the wire etc. of normal open switch and necessity by control system, control system with controlled system averages do not there is input and output.The concrete mode realizing measure loop series connection is: the output port of control module 13 is electrically connected with the input of relay 14 control system, and the output of relay 14 control system is electrically connected with cutter 11, and tool 12 is electrically connected with the input port of control module 13.The concrete mode realizing backfeed loop series connection is: the output port of control module 13 is electrically connected by the input of control system with relay 14, is electrically connected with another input port of control module 13 by the output of control system.Control module 13 can adopt PLC herein.
Lathe 1 can be the lathe 1 that conductive articles 2 processed by the various cutter 11 of any use, is specially automatic tapping machine in the present embodiment.Lathe 1 comprises frame 15 and rig floor 16, tool 12 is fixed on frame 15, rig floor 16 slides up and down to be arranged at frame 15 and the top being positioned at tool 12, cutter 11 is installed on bottom rig floor 16, the descending rear cutter 11 of rig floor 16 contacts with product 2 and makes measure loop conducting, the up rear cutter 11 of rig floor 16 departs from product 2, and measure loop disconnects.
Tool detection devices also comprises bus relay 17 and is arranged on the inductive switch 19 on rig floor 16, frame 15 is provided with trigger member 18, inductive switch 19 down conducting when trigger member 18, the control system of inductive switch 19 and bus relay 17 is connected with control module 13, bus relay 17 by control Cascade System in measure loop and backfeed loop.Due to the existence of inductive switch 19 and bus relay 17, only have rig floor 16 go downwards to certain position make bus relay 17 by after control system conducting, measure loop and backfeed loop just have possibility switched on, when rig floor 16 is in higher position, and measure loop and the equal no power of backfeed loop.What trigger member 18 was concrete can be one towards the shaft-like of inductive switch 19 or block elements, and inductive switch 19 for trigger point, plays the effect of travel switch with this element.
When only need carrying out adding man-hour in a position on product 2, the quantity of cutter 11 only has one.When needing the multiple positions to product 2 to add man-hour, can arrange multiple cutter 11 below rig floor 16, multiple cutter 11 corresponds to a product 2 and a tool 12.And the quantity of cutter 11 break detecting device repeat circuit 14 is equal with the quantity of cutter 11, and relay 14 and cutter 11 one_to_one corresponding.Specifically arrange 8 cutters 11 in the present embodiment and 8 relays, 14,8 cutters 11 are numbered D1-D8 respectively in circuit diagram, 8 relays 14 are numbered J1-J8 respectively, and bus relay is numbered J0.8 cutters 11 are in parallel in measure loop, and each cutter 11 is connected with the control system of corresponding relay 14, being connected in the feedback loop by control system of 8 relays 14.Only all could conducting without backfeed loop when fractureing at 8 cutters 11, as long as there is a cutter 11 to fracture, backfeed loop all will be caused to be disconnected.
Figure 5 shows that second embodiment of the present utility model, the difference of the present embodiment and a upper embodiment is to be provided with two rig floors 16 and two tools 12 in the present embodiment in lathe 1, two rig floors are respectively arranged with 8 cutters 11 for 16 times, have corresponding to each rig floor 16 and can process two products in two tools 12 respectively with the cutter 11 under 8 cutters 11 one to one 8 relays, 14, two rig floors 16.Wherein a tooling 11 and relay 14 will still be numbered D1-D8 and J1-J8 in circuit diagram, another set of cutter 11 and relay 14 continue to be numbered D9-D16 and J9-J16.
Identical with the circuit connecting relation of 8 relays 14 and a upper embodiment to 8 cutters 11 of identical product processing, and to different product processing cutter 11 correspondence relay 14 be connected into two backfeed loops respectively with control module 13 by control system, these two backfeed loops are in parallel.In the present embodiment, same control module 13 can monitor the working condition of two rig floors 16 simultaneously.Certainly, also can follow the mode in an embodiment, adopt two control modules 13 to monitor two rig floors 16 respectively.
According to the present embodiment, situation about obtaining when rig floor 16 quantity and tool 12 quantity are more can be estimated.
The utility model compared with prior art; because the utility model utilizes measure loop to form lasting, real-time automatic detection to cutter 11; and if cutter 11 fractures; control module 13 can receive the signal that backfeed loop disconnects; and then control lathe 1 is shut down, and is convenient to carry out fault elimination fault.
It is to be understood that; the signal focusing on making control module 13 obtain cutter 11 and whether fracture of the present utility model; namely the signal that backfeed loop is turned on or off is obtained; how to control lathe 1 further according to signal as control module 13 to shut down; belong to the prior art that those skilled in the art can be known easily, therefore do not provide concrete grammar in the utility model.
Above disclosedly be only preferred embodiments of the present utility model, its effect facilitates those skilled in the art to understand and implements according to this, certainly the interest field of the utility model can not be limited with this, therefore according to the equivalent variations that the utility model claim is done, the scope that the utility model is contained still is belonged to.
