Abstract
The invention provides a braking system for realizing C-axle double-way pneumatic operation of a numerically-controlled machine tool. The braking system comprises an air source. An output end of the air source is connected with an input end of a filtering and pressure-reducing unit. An output end of the filtering and pressure-reducing unit is connected with an input end of a two-position three-way electromagnetic valve. An output end of the two-position three-way electromagnetic valve is connected with an input end of a two-position five-way electromagnetic valve. An output end of the two-position five-way electromagnetic valve is connected with an input end of a speed control valve I. An output end of the speed control valve I is connected with an input end of a pneumatic gripper. The other output end of the two-position five-way electromagnetic valve is connected with an input end of a speed control valve II. An output end of the speed control valve II is connected with the other end of the pneumatic gripper. By adopting a pneumatic principle to control C-axle double-way driving, the braking system has the advantages of flexibility, simplicity, convenience, stability, economical efficiency, convenience in mounting and the like, and is adjustable in braking moment, easy to control and high in practical value.
Description
Technical field
The invention belongs to the numerical control machine tool technique field, be specifically related to a kind of for the pneumatic brakes of Digit Control Machine Tool realization C axle two-way.
Background technology
C axle brakes on the Digit Control Machine Tool adopts electromagnetic braking or brake fluid system mostly at present, and the electro-magnetic braking device cost is higher, eliminates gradually at present; The brake fluid system complex structure, the assembling trouble, the easy leakage of oil of oil cylinder, and hydraulic system easy break-down, the difficult maintenance affects operating efficiency, therefore is necessary to improve.
Summary of the invention
For solving the technical problem that exists in the prior art, provide a kind of and realize the pneumatic brakes of C axle two-way for Digit Control Machine Tool, have the characteristics of flexible and convenient.
The technical solution used in the present invention: be used for Digit Control Machine Tool and realize the pneumatic brakes of C axle two-way, has source of the gas, described source of the gas output is taken over filter decompressing unit input, an input of a long three-way electromagnetic valve of output termination two-bit triplet of described filtration decompressing unit, two five-way electromagnetic valve inputs of the output termination of the long three-way electromagnetic valve of described two-bit triplet, an output termination speed control valve I input of described two five-way electromagnetic valves, an input of described speed control valve I output termination gas pawl, another output termination speed control valve II input of described two five-way electromagnetic valves, another input of described speed control valve II output termination gas pawl.
Wherein, described another output of filter decompressing unit connects another input of the long three-way electromagnetic valve of two-bit triplet by pressure-reducing valve.
The present invention compared with prior art utilizes pneumatic principle to realize C axle Dual-path brake, has the characteristics such as flexible, easy, steady, economic, easy for installation, and braking moment can regulate, and is easy to control, has higher practical value.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing 1 a kind of embodiment of the present invention is described.
Be used for Digit Control Machine Tool and realize the pneumatic brakes of C axle two-way, has source of the gas 1, described source of the gas 1 output is taken over filter decompressing unit 2 inputs, an input of a long three-way electromagnetic valve 4 of output termination two-bit triplet of described filtration decompressing unit 2, described filter decompressing unit 2 another outputs connect long three-way electromagnetic valve 4 another inputs of two-bit triplet by pressure-reducing valve 3.Two five-way electromagnetic valve 5 inputs of the output termination of the long three-way electromagnetic valve 4 of described two-bit triplet, output termination speed control valve I 6 inputs of described two five-way electromagnetic valves 5, an input of described speed control valve I 6 output termination gas pawls 7, another output termination speed control valve II 8 inputs of described two five-way electromagnetic valves 5, another input of described speed control valve II 8 output termination gas pawls 7.
When lathe need to carry out the braking of C axle, source of the gas 1 ventilation, decompressing unit 2 is to the long three-way electromagnetic valve 4 of two-bit triplet after filtration, the long three-way electromagnetic valve of two-bit triplet this moment 4 operating positions are at right-hand member, control 5 actions of two five-way electromagnetic valves, make two five-way electromagnetic valve 5 operating positions at left end, the gas circuit with certain pressure of at this moment coming by source of the gas 1 enters the long three-way electromagnetic valve 4 of two-bit triplet, enter again two five-way electromagnetic valves 5, admission velocity control valve I 6 afterwards, thereby promote gas pawl 7 the C axle is stepped up, realize the C axle is braked; When gas pawl 7 need to unclamp, control 5 actions of two five-way electromagnetic valves, make two five-way electromagnetic valve 5 operating positions at right-hand member, at this moment the gas circuit with certain pressure that source of the gas 1 is come enters the long three-way electromagnetic valve 4 of two-bit triplet, enter again two five-way electromagnetic valves 5, admission velocity control valve II 8 is unclamped thereby promote gas pawl 7 afterwards.Because this road gas circuit is not passed through pressure-reducing valve 3, gas circuit pressure is higher, so this gas circuit is called high-pressure gas circuit.
Lathe is adding man-hour, sometimes need the certain damping rotary of C axle band, that can not stop again is too dead, at this moment the clamping force of gas pawl 7 does not just need too large, at this moment just need to control by pressure-reducing valve 3 size of gas circuit pressure, when this working condition of needs, with the gas circuit of certain pressure from source of the gas 1 decompressing unit 2 after filtration, pressure-reducing valve 3 is to the long three-way electromagnetic valve 4 of two-bit triplet, the long three-way electromagnetic valve of two-bit triplet this moment 4 operating positions are at left end, thereby realize the control to gas circuit pressure size, the final control that realizes gas pawl 7 clamping force sizes, gas circuit pressure at this moment is little than source of the gas 1 pressure, so this gas circuit is called again the low pressure gas circuit.
Above-described embodiment is preferred embodiment of the present invention, is not to limit the scope of the present invention, therefore all equivalences of being done with the described content of claim of the present invention change, all should be included within the claim scope of the present invention.
