Abstract

The utility model discloses a double piston cam type air compressor, with the main structural characteristics that the utility model adopts a camshaft to drive the cam, the flange of the cam drives the double piston to work. Because adopting the double piston, the utility model makes the positive work when operating, increasing the work efficiency, making the whole structure compact, reducing the weight and having no periodic vibration.

Description

Double-head piston cammingly air compressor

The utility model relates to a kind of air compressor structure, particularly a kind of cammingly air compressor with double-head piston.

Use most often crank connection reciprocating air compressor at present, sliding vane and screw-rod air compressor are also arranged.Wherein pressure height, the air displacement that produces with crank-linkage type is big.It is the straight reciprocating motion that rotatablely moving of crank is changed into piston that crank connects reciprocating air compressor, its working procedure is that a crank-connecting rod drives a piston, under the constant situation of rated speed, to strengthen air displacement, just must increase the quantity of piston, and the just necessary crank-connecting rod of piston of every increase, whole machine body also increases thereupon, and working efficiency is not high, energy consumption strengthens, and mechanical vibration strengthen.

The purpose of this utility model provides a kind of high working efficiency, and energy consumption is little, compact structure, the double-head piston cammingly air compressor of aperiodicity vibration.

The purpose of this utility model is achieved in that a kind of double-head piston cammingly air compressor, comprise body 1, in the supporting base 2 at body 1 middle part camshaft 3 is housed, cam 4 is installed on the camshaft 3, two rollers 7 are housed on the piston rod 6 of double-head piston 5, and roller 7 is inserted in flange 8 both sides of cam 4, and double-head piston 5 is connected with cam 4 by roller 7 and flange 8, cylinder 9 is equipped with at double-head piston 5 two ends, and cylinder 9 outer ends are cylinder head 10.Double-head piston 5 is the 1-6 group.On the piston rod 6 of double-head piston 5 cone axis 11 is housed.

Double-head piston cammingly air compressor provided by the utility model owing to adopt the structure of double-head piston, is all made positive work in the movement process of piston, improved working efficiency; The piston moving linearly has reduced connecting rod, makes compact integral structure, weight saving; Be rolling friction between the roller of piston and the cam, frictional force reduces, and piston work done of all wanting in to-and-fro motion, and is stressed even, eliminates the periodic vibration that is produced at the volley at connecting rod.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the left view of Fig. 1.

The utility model adopts following structure: a kind of double-head piston cammingly air compressor, comprise body 1, in the supporting base 2 at body 1 middle part camshaft 3 is housed, cam 4 is installed on the camshaft 3, two rollers 7 are housed on the piston rod 6 of double-head piston 5, and roller 7 is inserted in flange 8 both sides of cam 4, and double-head piston 5 is connected with cam 4 by roller 7 and flange 8, cylinder 9 is equipped with at double-head piston 5 two ends, and cylinder 9 outer ends are cylinder head 10.Double-head piston 5 is the 1-6 group.On the piston rod 6 of double-head piston 5 cone axis 11 is housed.

During the utility model work, rotate by flat key strap cam axle 3 by prime mover, camshaft 3 drives double-head piston 5 motions by flange 8, because double-head piston body 5 is installed in body 1 and the cylinder 9, the lead angle motion that roller 7 is pressed flange 8 in flange 8 when camshaft 3 rotations does reciprocating linear motion thereby drive double-head piston 5.There are cylinder 9 and cylinder cap 10 in double-head piston 5 two ends, and suction port 12 and air outlet 13 are arranged on the cylinder cap 10, the air that enters cylinder 9 by suction port 12 through double-head piston press 5 contract after air outlet 13 to gas tank.

Can be in the utility model according to different situations, 1-6 double-head piston 5 of dress is to adapt to the requirement of different operating occasion on camshaft 3.
