Head gas outlet is downward, and horizontal by 45 degree of angles.
Further, the spray head of air-jet device is rotatable.Rotation sprayer rotates left and right in scale removal process, Neng Gouda
To better cleaning effect.
The two sides of spray head are designed with limited block.The setting of limited block rotates spray head in limited block angular range, Neng Gougeng
It is directed at binding face cleaning well.
Since workpiece is in machining process, meeting bulk deposition is in fixture base, after work pieces process finishes taking-up, heap
Long-pending remnant clasts are easy to fall on the binding face that fixture base is bonded with workpiece, influence the precision of subsequent workpiece processing.It is excellent
Change ground, the longitudinal cross-section of fixture base is trapezoidal.The edge of fixture base is arranged to downward slope, makes to fall in fixture base
On remnant clasts fallen down along slope, reduce the clast on fixture base surface.
Working principle: the air pressure detection cleaning platform of work piece holder, workpiece are placed in fixture base in the utility model,
Clamp switch is opened, hydraulically operated fixture clamps workpiece, and workpiece inductor senses workpiece, while lathe PLC detects signal, control
First solenoid valve opens air pressure signal piping channel, and the clamping situation of workpiece is judged using pressure test device, if workpiece and folder
Have there are gas when clast, being passed through meeting gas leakage in the binding face of pedestal, atmospheric pressure value is lower than preset threshold value, lathe alarm, PLC
Issuing signal makes lathe that can not start processing；After workpiece is taken away, lathe PLC issues control instruction, closes the first solenoid valve, the
Two solenoid valves are opened, and air pressure signal piping channel is closed, and liquid honing channel is opened, and spray the gas with certain pressure intensity to folder
Tool pedestal is cleared up, and the clast of binding face is blown away；When workpiece is placed on fixture base again, workpiece inductor senses work
Part, lathe PLC issue control instruction, and second solenoid valve closes liquid honing channel, and air pressure signal piping channel is opened.Work as detection
When to atmospheric pressure value in acceptability limit, lathe normally starts processing.
The utility model has the advantages that the air pressure detection cleaning platform of work piece holder in the utility model, can real-time detection workpiece with
Whether fixture bottom surface is flat and fit, and has automatic clearing function, and bad product rate is effectively reduced, and substantially increases work effect
Rate.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model；
Fig. 2 is the principles of the present invention figure.
Specific embodiment
As shown in Figs. 1-2, the air pressure detection cleaning platform of the work piece holder of the utility model, including it is fixture base 5, hydraulic
Fixture 9, pressure test device 1, the air-jet device 2 for clearing up fixture base surface, the first solenoid valve 3, second solenoid valve 4,
Clamp switch.Pressure test device 1 is digital display type air pressure detector, facilitates observation numerical value.
Hydraulically operated fixture 9 and air-jet device 2 are located at the two sides of fixture base 5, and fixture base 5 is equipped with and work to be detected
Part is adapted locating slot, is fixed by positioning pin.Fixture base 5 is equipped with air flue 6, workpiece inductor 7；Air flue 6 is for diameter
The through-hole of 0.5mm, and be connected by PU tracheae with air pressure detector；Air pressure detector is connected with the first solenoid valve 3, the first electricity
Magnet valve is connected with gas source.Air-jet device 2 is connected with second solenoid valve 4 by PU tracheae, the first solenoid valve 3, second solenoid valve 4,
Clamp switch, workpiece inductor 7, chuck body are connected with lathe PLC.
The surface smoothness of fixture base 5 is Ra3.2, and flatness 0.02, longitudinal cross-section is trapezoidal, i.e. fixture base 5
Edge is equipped with downward slope.Since workpiece is in machining process, meeting bulk deposition works as work pieces process in fixture base 5
After finishing taking-up, the remnant clasts of accumulation are easy to fall on the binding face that fixture base 5 is bonded with workpiece, influence subsequent workpiece
The precision of processing.Optimally, the longitudinal cross-section of fixture base 5 is trapezoidal.The edge of fixture base 5 is arranged to downward slope,
It falls down the remnant clasts fallen in fixture base 5 along slope, reduces the clast on 5 surface of fixture base.6 diameter of air flue
Using 0.5mm, keep work piece holder air pressure detection effect preferable, while metal fragment in process being avoided to fall into air flue 6.
Air-jet device 2 includes jet pipe, jet pipe fixture, and 8 gas outlet of spray head of jet pipe is downwards and horizontal by 45 degree of angles.
Jet pipe fixture is adapted to jet pipe, is fastened by bolts part and is locked jet pipe, and jet pipe fixture and jet pipe are fixedly mounted on a rotation
On platform, turntable is fixed in fixture base 5 by bolt and nut.On the table top of turntable, the two sides of jet pipe are respectively provided with one piece
Limited block, limited block and jet pipe are in angle of 45 degrees.When air-jet device 2 works, turntable drives jet pipe to rotate left and right, and encounters two sides
Limited block when change direction of rotation automatically, i.e., the rotary jet in limited block angular range.Enable air-jet device 2 so more
The metal fragment on 5 surface of fixture base is blown away well.
When the present embodiment works, workpiece is placed in fixture base 5, opens clamp switch, hydraulically operated fixture 9 clamps workpiece
10, workpiece inductor 7 senses workpiece 10, while lathe PLC detects that signal, the first solenoid valve 3 of control open air pressure detection
Pipe passage.The compressed air for being 0.6Mpa by pressure, is then decompressed to 0.4Mpa through pressure regulator valve, is sentenced using pressure test device
The clamping situation of disconnected workpiece, can gas leakage if there are gases when clast, being passed through in workpiece 10 and the binding face of fixture base 5；In advance
If air pressure detection threshold value is 0.28Mpa, if gap is excessive between workpiece 10 and fixture base 5, the inspection of air pressure detector will lead to
The atmospheric pressure value measured is lower than preset barometric minimum value, that is, is less than 0.28Mpa, lathe alarm, PLC, which issues signal, makes lathe can not
Starting processing；After workpiece 10 is taken away, lathe PLC issues control instruction, closes the first solenoid valve 3, and second solenoid valve 4 is opened,
Air pressure signal piping channel is closed, and liquid honing channel is opened, and is sprayed the gas with certain pressure intensity and is carried out clearly to fixture base 5
Reason, the clast of binding face is blown away；When workpiece 10 is placed on fixture base again, workpiece inductor 7 senses workpiece 10, lathe
PLC issues control instruction, and second solenoid valve 4 closes liquid honing channel, and air pressure signal piping channel is opened.When detecting air pressure
When value is greater than 0.28Mpa, lathe normally starts processing；If atmospheric pressure value is still below 0.28Mpa, aforementioned process is repeated until fixture bottom
Seating face exists without substances such as metal fragments；In 10 process of workpiece, binding face, which can be monitored in real time, in pressure test device 1 is
It is no to fall into clast.Finally after workpiece to be processed completion of processing, clamp switch is closed, pressure test device 1 stops detection, takes away
Workpiece 10.
