Abstract
The invention relates to a cutter damage monitoring device which belongs to the field of equipment monitoring, in particular to a cutter damage monitoring device which monitors the damage of a cutter through a pressure sensor. The invention aims to provide the cutter damage monitoring device which can automatically control the action of a machine tool by sensing the change of the cutting force of the cutter. The cutter damage monitoring device comprises the sensor; the structural essentials are that: the sensor is arranged between the contact ends of a lead screw nut and a slide plate; the lead screw nut is arranged on a ball screw which corresponds to the lead screw nut; the ball screw is connected with a motor; a double-layer sliding saddle is fixed on the ball screw; the slide plate is fixed on the sliding saddle; a spindle is fixed on the slide plate; the cutter is fixed on the spindle; and the sensor is connected with the numerical control system of the machine tool.
Description
Technical field:
The invention belongs to the monitoring of equipment field, relate in particular to a kind of monitoring tool failure device of monitoring tool failure through pressure sensor.
Background technology:
The means of measuring tool failure have the direct method of measurement weighed with tool wear, damaged face size and the indirect method of measurement through measurement and tool wear, damage state based closely related signal, and switching signal comprises many-sided physical quantitys such as machinery, pneumatic, electromagnetism, optics, acoustics; Monitoring mode has the online non real-time method of the online in real time method of work in-process continuous monitoring and discontinuous monitoring in machining gap; To process relate to different form processings such as turning, brill, grinding; Aspect the signal processing, time domain and frequency-domain analysis method etc. are arranged.
Under the situation of a clamping workpiece, lathe will be accomplished operations such as end face milling, boring, tapping, fraising, bore hole automatically, if tool wear, damaged less than detecting is gently then damaged cutter, causes waste product, weighed and then damage lathe.Such as: drill bit has broken in workpiece, does not detect, and with regard to tapping, certainly will screw tap be interrupted.If reamer has worn and torn, do not detect, the workpiece size of being processed is just all little, causes waste product.If cutter under special circumstances, fracture does not suddenly detect, and lathe continues feeding, and the feed system of lathe will be damaged or the like.
On all kinds of lathes of field of machining, the tool wear in the process, damage are inevitably, now on common equipment, process; The wearing and tearing of cutter are to lean on operator's experience to judge to carry out sharpening or replacing; This way is also adopting at present, and its shortcoming is to lack advance, and people's experience plays a decisive role; Sometimes can go wrong inevitably, cause waste product or damage lathe.
Present horizontal or vertical machining centre does not at home take effective measures tool failure yet.
Summary of the invention:
The object of the invention is to provide a kind of monitoring tool failure device that moves through the variation automatic control machine tool of induction Tool in Cutting power.
For realizing above-mentioned purpose; The present invention adopts following technical scheme; The present invention includes sensor; Its structural feature is that sensor is arranged between feed screw nut and the slide plate contact jaw, and said feed screw nut is arranged on the corresponding with it ball-screw, and ball-screw is connected with motor; Be fixed with double-deck saddle on the leading screw; Be fixed with slide plate on the saddle, be fixed with main shaft on the slide plate, be fixed with cutter on the main shaft; Said sensor is connected with machine tool numerical control system.
As a kind of preferred version, the JQK-8001-21001 sensor that sensor according to the invention adopts German SANtec company to produce.
Beneficial effect of the present invention:
1, improves the utilization rate of cutter, reduce cost.
With the drill bit is example, before the present invention is not installed, and ability sharpening when a bit wear is very serious; Grind off a lot of materials, just scrapped sometimes, installed after the present invention; As long as bit wear has arrived cisco unity malfunction, just timely sharpening can also be processed behind the sharpening; Repeated multiple times has like this improved the utilization rate of cutter, reduces cost.
2, guarantee machining accuracy, improve the quality of products.
With the reamer is example, and before the present invention was not installed, after the reamer wearing and tearing, beginning was the roughness reduction of fraising; Then be size decreases, as not changing reamer, quality descends or causes waste product; Installed after the present invention, reamer is in case wear and tear the cutting force increase; In time change reamer, guarantee machining accuracy, improve the quality of products.
When 3, avoiding cutter to rupture suddenly, cause damage to lathe.
With the tapping is example, and during tapping, because the amount of feeding is big, feed speed is fast, if screw tap damages or twists off.This moment, cutting force was very big, as not stopping, will damaging the feed system of lathe, had installed after the present invention, and it will hard stop, and the protection lathe does not damage.
The present invention reduces cost except improving the utilization rate of cutter, guarantees machining accuracy, improves the quality of products, and when avoiding cutter to rupture suddenly, causes damage to lathe, has also improved the stability and the reliability of lathe widely.
Description of drawings:
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described further.
Fig. 1 is a structural representation of the present invention;
1 is motor, and 2 is sensor, and 3 is feed screw nut, and 4 is slide plate, and 5 is ball-screw, and 6 is main shaft, and 7 is cutter.
The specific embodiment:
As shown in Figure 1, the present invention includes sensor 2, sensor 2 is arranged between feed screw nut 3 and slide plate 4 contact jaws; Said feed screw nut 3 is arranged on the corresponding with it ball-screw 5; Ball-screw 5 is connected with motor 1, is fixed with double-deck saddle on the leading screw 5, is fixed with slide plate 4 on the saddle; Be fixed with main shaft 6 on the slide plate 4, be fixed with cutter 7 on the main shaft 6; Said sensor 2 is connected with machine tool numerical control system.
The JQK-8001-21001 sensor that the German SANtec of said sensor 2 employings company produces.
As shown in Figure 1, ball-screw 5 drives through motor 1, drives assembly on double-deck saddle and the saddle, moves back and forth, and realizes that adding the F.F. and the worker in man-hour advances.Work in-process tool wear, fracture, the cutting force, the main cutting force that produce when damaged are to act on the leading screw 5, thus the variation of the axial force of operation the such as when sensor 2 of installing the production of German SANtec company at feed screw nut 3 and slide plate 4 contact jaws is monitored drilling, in case cutter 7 has worn and torn; Variation has taken place in cutting force; When axial force changed to cutter 7 and may wear to regularly certain numerical value, sensor 2 sent warning, and sensor 2 is contained in feed screw nut 3 and slide plate 4 abutting ends; When adding axial force increase in man-hour; Show that abnormal situation has appearred in cutter 7 in the processing, sensor 2 sends signal, and work will stop immediately; Avoided cutter 7 fractures, can change cutter 7 this moment.The size of the power of signaling is adjusted according to operating mode.Control is to be realized by the digital control system of lathe.
