Abstract
The utility model relates to an eccentric sliding clock stroke regulating mechanism used by a plunger type or diaphragm type metering pump. The mechanism comprises an eccentric shaft, a sliding clock, a left top plate, a right top plate, a cross head, a plunger rod, a rotary sleeve and a regulating rod. The eccentric shaft drives the sliding block to move back and forth. The left top plate, the right top plate and the cross head lead the plunger rod to move back and forth in a straight line mode. The operation is stable. The rotary sleeve, the regulating rod, the left top plate and the right top plate regulate the reciprocating stroke of the mechanism in a stepless regulation mode. The utility model has the advantages of simplicity and low manufacturing cost.
Description
The utility model relates to the controlling mechanism of metering pump flow, specifically is a kind of eccentric shoe stroke control mechanism.
The stroke control mechanism of existing plunger type or diaphragm metering pump has N shape bent axle to regulate, multiple controlling mechanisms such as L shaped bent axle adjusting and eccentric cam adjusting, their composition includes N shape bent axle or L shaped bent axle, worm couple, eccentric cam, connecting rod, slide blocks, its complex structure, difficulty of processing is big, the fabricating cost height.As N shape bent axle controlling mechanism, connecting rod is inclined running in reciprocating stroke, tend to stuck, the influence normally the operation.This kind stroke adjustment structure, its journey error is bigger, the precision of influence metering.
The utility model is directed to the above-mentioned defective that the controlling mechanism of existing metering pump exists and designs, and provides a kind of simple in structure, and measuring accuracy is the eccentric shoe stroke control mechanism accurately.
Above purpose of design intends adopting following general plotting scheme to realize that this eccentric shoe stroke control mechanism includes eccentric shaft, slide block, left and right top board, crosshead, plunger rod, adjustable lever and rotation set, at eccentric shaft outer rim device slide block, right top board connects crosshead, and left roof is threaded with crosshead, and adjustable lever two is connected with rotation set with left roof respectively, rotation set is threaded with support, and crosshead is movably arranged in the support.
The good effect of the utility model production is that the rotation of eccentric shaft directly drives the to-and-fro motion of outer rim slide block, and is simple in structure, and crosshead and plunger are done reciprocating linear motion, and operates steadily; The rotation rotation set is regulated the clearance distance of left roof and slide block by adjustable lever, realizes step-less adjustment, makes the stroke metering accurate, and the metering that helps improving metering pump is accurate; Whole controlling mechanism is processed easily, and cost of production is low.
Below in conjunction with drawings and Examples, to technology contents further detailed description of the present utility model.
Fig. 1 is the utility model topology view.
The utility model embodiment is illustrated by the accompanying drawing that provides, shown in Figure 1, eccentric shaft 5 is connected with the assembling of support 8 bearings, the outer rim device of eccentric shaft 5 has slide block 7, its profile is garden cylindricality or rectangular, rotate with eccentric shaft 5 and to do back and forth that straight line moves, slide block 7 moves back and forth back and forth, by left and right top board 4 and 6 crosshead 9 and plunger rod 10 is done reciprocating linear motion.Left roof 4 is threaded with the inner nut 3 of crosshead, connects with adjustable lever 2 keyways that are connected with rotation set 1 again, and rotation set 1 is threaded with support 8, and right top board 6 connects crosshead 9, and left and right top board 4 and 6 is positioned at the both sides of slide block 7.Rotation rotation set 1 drives left roof 4 through adjustable lever 2 and rotates relative to inner nut 3, divides left and right moving in the inner chamber in crosshead, changes left and right top board 4 and 6 distances with slide block 7, realizes the step-less adjustment reciprocating stroke.The relative position of regulating left roof 4 and slide block 7 changes the stroke of crosshead 9; Left and right top board 4 is consistent with slide block 7 width with 6 distance, then is the total travel of this mechanism, i.e. the twice of throw of eccentric; Distance in left and right top board 4 and 6 adds 2 times of throw of eccentric greater than slide block 7 width less than slide block 7 width, and just rotatable rotation set 1 carries out step-less adjustment, reaches required measuring requirement.
