The end of the eccentric sleeve connected with the gear wheel is of a concentric structure, so that transmission of the gear wheel is facilitated; and the end of the eccentric sleeve connected with the connecting rod is of an eccentric structure, so that the connecting rod can be driven to reciprocate when the eccentric sleeve moves. Besides, a structure for converting rotational movement into linear movement is quite simple, so that production, assembly and maintenance costs are greatly reduced, and the mechanical diaphragm metering pump is high in competitive strength in markets.
Description
Technical field
The utility model relates to a kind of mechanically actuated diaphragm metering pump, is specially a kind of mechanically actuated diaphragm metering pump diaphragm driving mechanism.
Background technique
As everyone knows, in mechanically actuated diaphragm metering pump, nearly all can use rotatablely moving of motor is transformed into linear reciprocating motion by a switching mechanism.At present domestic manufacturer substantially all adopts the cam link technology, and due to the existence of processing or build-up tolerance, no matter how accurate you adopt process equipment and superb assembling level how, all can there be with desirable benchmark certain deviation in it.The at present domestic scheme that generally adopts is at connecting rod and diaphragm connection part, one crosshead automatic guide centering body to be set, and solves cam radial center and diaphragm center automatic centering problem.Such device is very ripe, almost becomes classical scheme, and nearly all Machine Design book has independent introduction.But it exists a lot of shortcomings really: 1, the crosshead mechanism machining accuracy of centering requires very high, otherwise meeting Caused Vibration accelerated wear test, simultaneously material hardness and the toughness that adopts is had high requirement, need to adopt quenching with Subsequent tempering, inevitable like this its cost that makes is very high; 2. assembling has high requirements, and requires like this assembly crewman's technology and experience aspect that high requirement is arranged; 3, maintenance cost is very high, in case this mechanism wear is scrapped, many repair companies adopt direct replacing to renew basically.And this cover mechanism generally is used on hard material, and for example air compressor all generally adopts time mechanical mechanism.Because the diaphragm material of Machinery Diaphragm Pump is flexible material, domestic manufacturer all can substitute crosshead mechanism centering scheme in the urgent need to a cover, produces to reduce, the cost of assembling and maintenance.
The model utility content
For problems of the prior art, the purpose of this utility model is to provide a kind of technological scheme of mechanically actuated diaphragm metering pump diaphragm driving mechanism.
Described a kind of mechanically actuated diaphragm metering pump diaphragm driving mechanism, comprise the pump head, diaphragm, connecting rod, base and the motor that cooperatively interact, it is characterized in that on the output shaft of described motor, interference arranges small gear, small gear is connected with the gearwheel of base top by Timing Belt; Be provided with bearing pin in base top, be equipped with eccentric bushing on bearing pin, described gearwheel and eccentric bushing interference fit; Be provided with bearing on the eccentric bushing of gearwheel one side, on the bearing outer rim, interference arranges connecting rod, and the connecting rod free end arranges diaphragm, and gearwheel is by the motion of eccentric bushing drivening rod.
Described a kind of mechanically actuated diaphragm metering pump diaphragm driving mechanism is characterized in that described eccentric bushing right-hand member is set to concentric structure, and the eccentric bushing left end is set to eccentric structure, and gearwheel is arranged on the eccentric bushing right-hand member, and bearing is arranged on the eccentric bushing left end.
Described a kind of mechanically actuated diaphragm metering pump diaphragm driving mechanism is characterized in that described eccentric bushing is rotatably assorted by needle bearing and the bearing pin that is arranged on base top.
Described a kind of mechanically actuated diaphragm metering pump diaphragm driving mechanism is characterized in that described eccentric bushing both sides all arrange needle bearing.
Described a kind of mechanically actuated diaphragm metering pump diaphragm driving mechanism is characterized in that described bearing pin two ends are bolted on base.
Described a kind of mechanically actuated diaphragm metering pump diaphragm driving mechanism is characterized in that described motor is fixed by screws in base one side.
The utility model is according to the characteristics of mechanical diaphragm pump diaphragm flexibility, cancelled crosshead automatic guide centering body in prior art, and the eccentric bushing structure that adopts machinery realizes rotatablely moving straight-line conversion, be about to eccentric bushing and gearwheel connecting end and be set to concentric structure, facilitate the gearwheel transmission, eccentric bushing and connecting rod connecting end are set to eccentric structure, when making the eccentric bushing motion, connecting rod are moved reciprocatingly; This straight-line transformational structure that rotatablely moves is very simple, greatly reduces the cost of production, assembling and maintenance, makes mechanically actuated diaphragm metering pump that larger competitive advantage be arranged on market.

In figure: 1-connecting rod, 2-gearwheel, 3-Timing Belt, 4-eccentric bushing, 5-bearing, 6-bearing pin, 7-bolt, 8-base, 9-motor, 10-small gear, 11-needle bearing, 12-diaphragm, 13-pump head.
Embodiment
Below in conjunction with Figure of description, the utility model is described further:
A kind of mechanically actuated diaphragm metering pump diaphragm driving mechanism, comprise the pump head 13, diaphragm 12, connecting rod 1, base 8 and the motor 9 that cooperatively interact, diaphragm 12 is isolated into a closed chamber with pump head 13, motor 9 is fixed by screws in base 8 one sides, interference arranges small gear 10 on the output shaft of motor 9, and small gear 10 is connected with the gearwheel 2 at base 8 tops by Timing Belt 3; Base 8 tops are provided with bearing pin 6, and bearing pin 6 two ends are fixed on base 8 by bolt 7, are equipped with eccentric bushing 4 on bearing pin 6, and eccentric bushing 4 both sides all are rotatably assorted by needle bearing 11 and the bearing pin 6 that is arranged on base top; Eccentric bushing 4 right-hand members are set to concentric structure, eccentric bushing 4 left ends are set to eccentric structure, gearwheel 2 interference are arranged on eccentric bushing 4 right-hand members, eccentric bushing 4 left ends arrange bearing 5, on bearing 5 outer rims, interference arranges connecting rod 1, connecting rod 1 free end is spirally connected diaphragm 12 is set, and gearwheel 2 is by eccentric bushing 4 drivening rod 1 motions like this.
Working procedure: machine operation, drive pinion rotation, owing to being provided with Timing Belt, motor will drive gearwheel and eccentric bushing rotates, because the eccentric bushing right-hand member is concentric structure, and can be with the gearwheel uniform rotation, and the eccentric bushing left end is eccentric structure, will drivening rod after eccentric bushing rotates like this do the to-and-fro motion of vertical direction, make diaphragm do up and down flexing motion, thereby drive the pump head pumping liquid.
Because diaphragm self is flexible structure, when eccentric bushing rotates to forefront or rear, in rational extent of the error, can rely on the flexing of self doing of diaphragm to move, so this structure can replace traditional crosshead automatic guide centering body.
