Embodiment
Further specify embodiment below in conjunction with accompanying drawing with optimal way.
With reference to Fig. 1; Innovative point of the present invention is that cylinder head 14 is to be even number to arrange a plurality of disjunctors and seal together and be installed on the air valve plate 12; Per two cylinder head 14 are connected with valve plate suction port 22 and valve plate air outlet 23 with a cylinder liner 20; Valve plate suction port 22 is arranged on the air valve plate 12 with valve plate air outlet 23, and cylinder liner 20 is installed on the piston fixed plate 11, and piston fixed plate 11 is installed on the frame 7; Piston fixing column 21 in the piston 19 also is that a plurality of being installed in together moves up and down on the plate 10, and moving up and down has two linear bearings 9 to be installed in respectively on two mobile stationary axle 8 on the plate 10, moves stationary axle 8 and is installed on the piston fixed plate 11 or on the frame 7; A plurality of cylinders air outlet 15 on the described cylinder head 14 is connected together becomes an air outlet.Described cylinder head 14 be 6 disjunctors together, corresponding cylinder liner 20 be 5 disjunctors together, become a unit combination; Have only suction port 16 and the valve plate suction port 22 that is arranged on the air valve plate 12 to be connected on first cylinder head 14 with first cylinder liner 20; Last cylinder head 14 also has only air outlet 15 and the valve plate air outlet 23 that is arranged on the air valve plate 12 to be connected; Between described cylinder head 14 and the air valve plate 12 seal ring 13 is installed; Each valve plate suction port 22 a corresponding suction port valve block 18, air outlet valve block 17 of each valve plate air outlet 23 corresponding installation installed.Described power plant are variable-frequency motors 24.Described transmission device is the connecting rod of eccentric wheel structure.This structure then is that the straight line that is implemented in the cylinder liner 20 rises and straight line decline for leather bucket 19, can significantly reduce wear, and also just increases substantially working life, and reducing noise, also makes working environment quiet; And realize big flow pressurized gas and inhale vacuum function; Owing to reduce wear, also reduce power consumption.
Practical implementation is following: variable-frequency motor 24 usefulness belts 25 drive rotating spindle 1 and rotate; Rotating spindle 1 is installed on the eccentric wheel 2, and eccentric wheel 2 usefulness bearings 3 are installed on the connecting rod 4, and connecting rod 4 upper ends and movable axis 5 are fastenedly connected; Movable axis 5 flexibly connects with movable axis support 6; Movable axis support 6 is installed in and moves up and down on the plate 10, piston fixing column 21 with move up and down plate 10 and be fastenedly connected, piston fixing column 21 is fastenedly connected with leather bucket 19; Move up and down and install on the plate 10 two linear bearings 9 and mobile 8 movable cooperations of stationary axle; Move stationary axle 8 fastening being installed on the piston fixed plate 11, piston fixed plate 11 fastening being installed on the frame 7 realize that leather bucket 19 moves up and down when work.5 cylinder liner 20 fastening being installed on the piston fixed plate 11; Also be tightly connected with air valve plate 12; 6 cylinder head 14 disjunctors are installed on the air valve plate 12 with seal ring 13 sealings, by diagram valve plate suction port 22 and valve plate air outlet 23 are set on the air valve plate 12; 16, the second of first cylinder cap suction ports are cylinder cap air outlets 15 on the cylinder head 14, and are later and the like, are air outlets 15 on cylinder head 14 in the end; The air outlet valve block 17 that is arranged on the air valve plate 12 is also installed like diagram with suction port valve block 18.
Working principle: rotating spindle 1 rotates under variable-frequency motor 24 drives; Eccentric wheel 2 rotates simultaneously; Thereby connecting rod 4 is bobbed and woven; Realize movable axis 5, move up and down plate 10 and move up and down, then leather bucket 19 rise and fall in cylinder liner 20, rotating spindle 1 whenever turn around make leather bucket 19 in cylinder liner 20 rise and fall each once.When leather bucket 19 rises, can make suction port valve block 18 seal valve plate suction port 22 voluntarily, make air pressure indentation valve plate air outlet 23 in the cylinder liner 20 get into cylinder cap air outlets 15 and export, realize compressed-air actuated requirement.When leather bucket 19 descends in cylinder liner 20, can make air outlet valve block 17 seal valve plate air outlet 23 voluntarily, air is got in the cylinder head 14 by cylinder cap suction port 16, get in the cylinder liner 20 from valve plate suction port 22 again.When rotating spindle 1 rotates; Each leather bucket 19 is risen and straight line decline at cylinder liner 20 cathetus simultaneously; Leather bucket 19 was to flexibly connect with 21 past of piston fixing column; Cam link mechanism or eccentric wheel connecting rod mechanism all can go up piston fixing column 21 also gradient top or leave behind with angularity of connecting rod swing, and making weares and teares between piston fixing column 21 and the leather bucket 19 aggravates, and reduce working life greatly.Piston fixing column 21 is fastenedly connected with leather bucket 19 now, has eradicated wearing and tearing, has also just improved working life greatly.The needs of the big flow pressurized gas of simultaneous adaptation demand unit.
Above-mentioned is the situation of a unit combination, also can make up a plurality of unit, as two unit combination then transmission device be two pairs, variable-frequency motor can adopt connecting shaft to install.
More than shown in Figure 1 be the embodiment of the present invention with optimal way; Demonstrate substantive distinguishing features of the present invention and remarkable progress; Can be according to the needs of reality use; Under teachings of the present invention, it is carried out the equivalent modifications of aspects such as shape, structure, but all within the protection domain of present technique scheme.
