Description
Technical field
The present invention relates to numerical control gang drill technical fields more particularly to a kind of concealed mute for numerical control gang drill quickly to arrange
Air valve, the Mute cylinder for being equipped with concealed mute rapid escape valve and the mute type for being equipped with concealed mute rapid escape valve
Numerical control gang drill device.
Background technology
In today that present informationization technology is popularized, traditional industry and electronics technology informationization depth integration are enterprise developments
And the only way which must be passed of transition, efficient, accurate, the flexibility customized production of Numeric Control Technology are that original non-numerical control industry is admired very much
, woodworking is as industrial eight group industries, and relatively the people's livelihood, is always one piece of ignored plate, number in industrial development
The universal and infiltration of control technology, allows entire industry rapidly to become the market abroad competed, the NC postprocessing wood got ahead of others
Work enterprise not only shoots up and forms intense impact to traditional carpenter's furniture market, has grasped the language for dividing market cake
Power.
And two big elements of woodworking numerical control transformation are going forward side by side for software and hardware, software is that numerical control software executes
System, hardware are the powered actuation mechanism component of the electro spindle and gang drill that are different from conventional motors.
Electro spindle is the power core component for modernizing numerical control switch-power in gang drill, and company deep ploughs on electro spindle product
For many years, more stable research and development, producing and selling system are formd, accumulates certain technology and the market experience, and opened with 2015
Begin research and development gang drill.
Existing gang drill generally uses common cylinder, including cylinder body and the end cap that is arranged on cylinder body,
The end cap includes valve body 1 and connector 3, and as shown in Figure 1 and Figure 2,3 center of connector offers air admission hole 4, and 1 center of valve body offers
Venthole 2, gas enter through air admission hole 4, venthole 2 in cylinder body.However such air cylinder structure is more single, itself is not
There is air return mechanism, needs that air return mechanism is in addition arranged in cylinder body, either (solenoid valve is external by the way of external
Formula fast-discharge valve) return-air is carried out, the shortcomings that solenoid valve vents is that 1, exhaust pathway is longer, and stroke is longer；2, solenoid valve is as movement
Component, contacts in compressed air that moisture is more, easy tos produce cylinder push-rod retardance, influences exhaust efficiency, causes knife bar retraction slow
Slowly, influence the drilling of numerical control gang drill to safety such as knife processing, this has been considerably improved the cost of manufacture of cylinder, complicated cylinder it is whole
Body structure.
