Abstract
The utility model relates to a vacuum cam compression pump, comprising a casing, a cam, a shaft, an air-matching wheel, a cover, etc; one end of the cam is provided with a piston and the air-matching wheel which is made into a curve groove of equal acceleration and deceleration, and the size of the groove forms a slide fit with that of the sliding wheel; the vacuum compression pump of the utility model is widely used in the trades of machinery, light industry, chemical industry, food, medicine, printing, etc.
Description
The utility model relates to a kind of vacuum compression air pump.Particularly a kind of cammingly vacuum compression air pump belongs to the machine tool class.Just the commercially available air pump product of printing sees that nothing more than two types: a kind of is the linkage type type at present.Another kind is the Wiper blade type type.More than two types air pump.Power consumption is big, and connecting rod crank and eccentric structure are easy to generate vibration, and weight and volume is all big, complex structure, expends a large amount of raw material, and cost cost height add that maintenance at ordinary times is extremely inconvenient, so the utmost point need update.
The purpose of this utility model provides that a kind of volume is little, in light weight, power is big, cammingly vacuum compression air pump simple in structure.
The utility model is to realize like this; It is made up of housing, cam (cylindrical body cam) axle, two pistons, distribution wheel, lid, pulley etc.At an end of cam piston and distribution wheel are installed, cam be make wait quicken and etc. the deceleration curve groove, the size of groove is big or small the same with pulley, distribution is taken turns more than two.
Cammingly vacuum compression air pump of the present utility model is that a kind of volume is little, in light weight, power is big, power consumption is little, not vibration, part is few in addition, cost is low, maintenance is convenient.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 a 1b is a structural representation of the present utility model.
Fig. 2 a, 2b are cam structure schematic representation of the present utility model.
Shown in Fig. 1 a, 1b shown in Fig. 2 a, the 2b, axle 3 is loaded onto an assembly turbine 5 cams 2 pistons 4 housings 1, axle 3 is contained in the cylinder, loads onto another assembly turbine 5 simultaneously, the nut on spools 3 two is screwed, after load onto and cover 6, pulley 7 is contained in wait quickening of cam 2 and waits in the deceleration curve groove, and the curvilinear groove on the cam 2 processes with special purpose machine tool, and the size of groove cooperates with the big or small activity of pulley 7, axle 3 is subjected to the external force effect, and cammingly vacuum compression air pump just can be worked.
Cammingly vacuum compression air pump of the present utility model, housing 1 is a piston cylinder, cam 2 is loaded onto two pistons 4, axle 3 is loaded onto cam 2 and distribution wheel 5, load onto axle 3 in the housing 1, on the cam 2 etc. acceleration and etc. load onto pulley 7 in the deceleration curve groove, because cam 2 endoporus are loaded onto an inner sleeve 8 again, on inner sleeve and the axle straight key (not marking among the figure) is housed, inner sleeve external diameter and cam 2 endoporus are loaded onto the straight circular groove 9 of the quartering again, put into steel ball 10 in the groove, axle 3 moved by the external force rotation and cam 2 will be along crankmotion in the quartering groove, add the distribution effect of distribution wheel 5 again, this makes a pneumaticpiston of cam 2 become vacuum suction and this makes cam 2 other end pneumaticpiston compression exhausts, so just reaches the purpose of vacuum suction compression exhaust.
Claims (3)
1, a kind of cammingly vacuum compression air pump comprises housing 1, cam 2, axle 3 lids 6, pulley 7, inner sleeve 8, straight circular groove 9, steel ball 10, it is characterized in that at an end of cam 2 piston 4 and distribution wheel 5 being installed.
2, by the described cammingly vacuum compression of claim 1 air pump, it is characterized in that described cam 2 make wait quicken and etc. the curvilinear groove of deceleration, being slidingly matched of the size of groove and pulley 7 sizes.
3, by claim 1,2 described cammingly vacuum compression air pumps, the quantity that it is characterized in that described piston 4, distribution wheel 5 is respectively more than two.
