Abstract
The utility model provides an anti-collision cutter, aims to overcome the limitation of the conventional software anti-collision measures in complex environments, and provides an anti-collision scheme for hardware. The anti-collision cutter comprises a cutter handle, a pad blade, a blade locking pin, a blade, a film type pressure sensor and a pressing plate, wherein a film of the film type pressure sensor is bonded to a cylinder on the upper end of the blade locking pin; metal terminals of the film type pressure sensor pass through a square groove formed in the cylinder after being bent; a signal wire is led out from through holes in the blade locking pin; and a mounting hole of the blade is in closely contact with the film type pressure sensor. By the anti-collision cutter, when vehicle collision occurs, the impact force applied to the blade is transferred to the film type pressure sensor and is output to a numerical control system. When an output pressure value is larger than a pressure value set by the system, cutter feeding is stopped, and an alarm is prompted, so that the collision between the cutter and a workpiece is controlled within a small range, and damage to the workpiece, the cutter and a machine tool is avoided.
Description
Technical field
The utility model relates to a kind of crashproof cutter, espespecially a kind of crashproof clamped cutter.
Background technology
At present, digital control processing is the main processing mode of component of machine, happens occasionally but hit the cutter accident in the today's numerical control process, has not only improved the cutter proportion of goods damageds and machine upkeep frequency, and is more serious, also may cause lathe to be scrapped and personal injury.Because Modern NC Machine Tool has all been installed limit switch, the possibility that cutter and lathe bed miscellaneous part bump is less, and most cuttves that hit all occur between cutter and the workpiece.And the major measure that prevents from present hitting cutter is to utilize simulation software to simulate processing or set the range of work of safety by system of processing, because the environment of processing is comparatively complicated, the shape of workpiece is also complicated and changeable, can not stop to hit the generation of cutter accident fully by the method for software set.In view of the limitation of software Anticollision Measures, the existing urgent need added the crashproof measure of a kind of hardware, to prevent from hitting the generation of cutter accident.
The utility model content
In order to overcome the limitation of software Anticollision Measures, the utility model provides a kind of crashproof clamped cutter, can the Real-Time Monitoring cutter and workpiece between active force, when this active force during greater than setting value, cutter feed-disabling, and system prompt is reported to the police.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
The utility model comprises, handle of a knife, equipment on turning-machine for setting-on cutting tools, insert retention pin, blade, thin-film pressure sensor, pressing plate and bridge screw.Described handle of a knife is provided with two screwed holes.Two screwed holes on the described handle of a knife are through hole, and described equipment on turning-machine for setting-on cutting tools is fixed on the screwed hole by the insert retention pin, and described pressing plate is connected with another screwed hole by bridge screw.
Described equipment on turning-machine for setting-on cutting tools is installed on the described handle of a knife, and fixes by the screw thread of described insert retention pin lower end.
The upper end of described insert retention pin is cylinder, is used for twining the diaphragm of pasting described thin-film pressure sensor.Described cylinder is provided with square groove, is provided with through hole in the described insert retention pin, and described square groove and through hole are used for the wiring of thin-film pressure sensor.Described thin-film pressure sensor adopts the piezoelectric type thin film sensor, piezoelectric material film can be effectively pressure when being subject to impacting change into corresponding electric charge and derive.
The lower end of described bridge screw is fixed on the screwed hole of described handle of a knife, and the upper end is connected with described pressing plate.
Described blade is installed on the handle of a knife by the insert retention pin, the diaphragm close contact of its installing hole and described thin-film pressure sensor, and be fixed on the handle of a knife by described pressing plate.
The beneficial effects of the utility model are: the laterally or radially elaboration power that acts on the blade can both be communicated on the piezoelectric membrane effectively, and can effectively transfer the output of electrical analogue amount to.Can not only monitor the active force between the cutter and instrument in the process, and when hitting cutter, also feed-disabling and prompting are reported to the police in time, make in the bump of cutter and workpiece occurs in more among a small circle, prevent the damage of workpiece, cutter and lathe.
Description of drawings
Fig. 1 is assembling schematic diagram of the present utility model;
Fig. 2 is structural representation of the present utility model.
Among the figure, 1, equipment on turning-machine for setting-on cutting tools, 2, the insert retention pin, 3, square groove, 4, thin-film pressure sensor, 5, blade, 6, through hole, 7, pressing plate, 8, bridge screw, 9, handle of a knife.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of crashproof cutter comprises handle of a knife 9, equipment on turning-machine for setting-on cutting tools 1, insert retention pin 2, blade 5, thin-film pressure sensor 4 and pressing plate 7.Handle of a knife 9 is provided with two tapped through holes, is used for installing insert retention pin 2 and bridge screw 8.Equipment on turning-machine for setting-on cutting tools 1 is installed in the cutter groove of handle of a knife 9, and is fixed on the handle of a knife 9 with insert retention pin 2 lower end screw threads.Thin-film pressure sensor 4 sticks on the insert retention pin 2 upper end cylinders, passes square groove 3 after its metal terminal bending, and the through hole 6 that the signal conductor of drawing passes insert retention pin 2 passes the below of cutter hub, and links to each other with digital control system.Blade 5 is installed in insert retention pin 2 tops, and the film close contact of its centre bore and diaphragm type piezoelectric transducer 4.Pressing plate 7 is fixed on the handle of a knife 9 by bridge screw 8, by rotary pressure plate 7 blade 5 is fixed in the cutter groove.
When hitting cutter, blade 5 is subject to huge impulsive force, and this impulsive force is communicated on the thin-film pressure sensor 4, makes it produce electric charge output, converts Voltage-output to by charge amplifier.Because piezoelectric membrane output voltage and suffered pressure are one to one, so digital control system only need detect the size that output voltage just can obtain pressure.Set in advance an alarm pressure value in system, this value size is surrendered between powerful and the cutter material yield strength between workpiece material.When output pressure value during greater than the force value of default, stop tool feeding, and prompting reports to the police, make in the bump of cutter and workpiece occurs in more among a small circle, prevent the damage of workpiece, cutter and lathe.
The above only is implementation case of the present utility model, but mechanism characteristics of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification all are encompassed among the claim of the present utility model.
