Description
Technical field
The present invention relates to the automatic switchover sharing valve of digit ctrol machine tool field, especially numerical control five-axle lathe cooling pneumatic system
Block.
Background technology
At present, existing cnc boring and milling machine cooling pneumatic system all uses split-type design, i.e. cooling system has a set of special
Element and design, pneumatic system also have a set of special element and principle, and two systems are unable to intercommunication and mutually used.Such as Fig. 3 institutes
Show, existing ram cooling, pneumatic system are exactly respectively to have a set of autonomous control system, often cover system and are required for individually with corresponding
Executive component, although these elements are standard components, therefore cause that device layout is not compact, number of elements is huge, plant maintenance
The problems such as inconvenient.So also just increase the manufacturing cost and maintenance cost of equipment.
The content of the invention
It is an object of the invention to provide a kind of pneumatic function automatic switchover sharing valve of the cooling in machine tool control system
Block, cooling system and pneumatic system share a set of control module and valve module, realize automatic hydraulic pressure handoff functionality.
The pneumatic function automatic switchover sharing valve block of cooling in the machine tool control system of the present invention, including equipment control
Hydraulic pressure program in system, switch, valve member, it is characterised in that cooled down including automatically switching the control program of pneumatic function and go out,
The valve member component that entrance concentrates in together；Perform the control program and cool down the hydraulic pressure of pneumatic function switch, electrical connection automatically：
Outer cold entrance is respectively symmetrically connected with interior cold entrance, and outer cold entrance connects outer cold flow switch, outer cold check valve, and it is outer cold to connect
The dynamic outer cold outlet of cleaning check valve connection of switching valve, outer cold air, the pneumatic switching valve being connected with pneumatic inlet are dynamic clear with outer cold air
Moved again by interior cold air after clean check valve connection and clean cold switching valve in check valve connection, cold cut in cold and right-angle head in end mill head
Use cold outlet in three two-way valve to right-angle heads, cold outlet in end mill head instead；Cold flow switch, interior cold list in interior cold entrance connection
It is connected to valve, and by three two-way valves of interior cold switching valve connection, by the dynamic cleaning check valve connection of interior cold air with pneumatic inlet
Pneumatic switching valve；The accessory head taper hole cleaning switching valve being connected with pneumatic inlet is connected the pneumatic hermetic seal of accessory head and exports, be attached
Part head pneumatically bores empty cleaning outlet；
Automatically switch and cool down the control program of pneumatic function：First have under Step7-300 language environments that edit definition can
Storage and the PLC variables for transmitting numerical value, the data block of variable is stored well according to application definition, and the good a certain address of application definition becomes
Amount, editor cool down the PLC program of pneumatic function auto-changeover control；It is interior cold to judge whether job instruction needs, if necessary
Cold pump and interior cold switching valve in startup, and in being provided for end mill head or right-angle head by cold switching valve in end mill head and right-angle head
It is cold, if it is interior it is cold complete if close in cold check valve and the internal cold carry out line clear of the dynamic cleaning check valve of cold air in starting, so
Cold pump work in stopping afterwards；Pneumatic switching valve starts PLC program and judged, if necessary to accessory head taper hole cleaning function, then annex
Nose cone hole cleaning switching valve starts, and realizes the taper hole cleaning function of machine tool accessory head；If necessary to outer cold function, then start outer cold
Pump and outer cold switching valve, when it is outer it is cold complete to close outer cold check valve, then the dynamic cleaning check valve of outer cold air carry out outside cold pipeline it is clear
It is clean, then stop outer cold pump；Pneumatic switching valve is again started up editing PLC program, completes whole control flow.
Due to using above-mentioned technical proposal, the beneficial effects of the invention are as follows：
1st, the present invention only uses a set of control system on the premise of cooling, pneumatic function is ensured, using a set of sharing valve
Block is completed to cool down pneumatic automatic switching function, it is possible to reduce the quantity of element reaches more than 40%, significantly saved element into
Sheet and maintenance cost；
2nd, in lathe running, the present invention is to control the valve member of coolant and gas to cut by shared control system
Change, so can significantly improve the operational efficiency of lathe, at least 10% operating efficiency can be improved.
3rd, the present invention reduces fault rate, so the reliability of lathe also accordingly improves due to reducing number of elements.
