The bounce of the disk of fluidity tester.With the increase of analyzer usage time, the outer circumferential surface of cam and the lower end of push rod it
Between generate abrasion due to the extrusion friction of the two so that occur gap between the outer circumferential surface and push rod of cam, while by first
Support member and the second supporting item slide upwards, driving motor and cam are driven to slide upwards therewith, one end of motor shaft is installed on drive
On dynamic motor, the other end is installed on by bearing on the second supporting item so that the both ends of motor shaft are limited in vertical direction, are kept away
Cam run-off the straight under the bounce with push rod on motor shaft is exempted to be threaded onto so that the outer circumferential surface of cam and the lower end of push rod
The state fully touched is maintained at, so that the bounce amplitude of disk maintains stable state, adds water dispenser mortar fluidity
Detection data accuracy.
Further preferably：The support base includes chassis, vertical two fixed plates and the fixation being fixed on chassis
Sleeve in dead plate upper end face, two fixed plate parallel intervals are set and with the axisymmetrical of sleeve, and the push rod is threaded onto
In sleeve.
Using the above program, the setting on fixed plate and chassis so that sleeve is in vacant state, plays a supporting role to push rod,
Meet the bounce of push rod and disk, two fixed plate parallel intervals set and with the axisymmetrical of sleeve, add the knot of sleeve
Structure stability, simple in structure, production cost is low.
Further preferably：First supporting item and the second supporting piece structure are identical, and with the axis pair of the sleeve
Claim to set.
Using the above program, symmetrically arranged first supporting item and the second supporting item cause the fixed form at motor shaft both ends
Unanimously, the stability of motor shaft is added, at the same it is easy to operation.
Further preferably：First supporting item and the second supporting item include the support being arranged in the fixed plate
Plate and several fasteners for fixed support plate, the mounting hole of strip is offered in support plate vertically, and fastener is threaded onto
It in mounting hole and is fixed in fixed plate, the body is fixed in the support plate of the first supporting item, vertical in the fixed plate
The through hole walked for the motor shaft is offered, one end of body of the motor shaft away from driving motor is piercing in outside through hole simultaneously
It is installed on by bearing in the support plate of the second supporting item.
Using the above program, unscrew fastener, push up support plate, driving motor is under the action of support plate along peace
Dress hole slides upwards, to realize that the height of driving motor is adjusted, adds the stability of motor shaft and cam so that outside cam
