Abstract
The utility model discloses an upper ram connecting mechanism of an internal mixer, which comprises a piston rod and an upper ram, wherein, the upper ram is connected with the piston rod through a pin shaft; the pin shaft is inserted into a hole formed on the piston rod; a composite bearing is sleeved on the outer side of the pin shaft; the pin shaft is axially positioned through a shaft end retaining ring; and a clearance between the hole formed on the piston rod and the pin shaft is larger than a clearance between the lower end surface of the piston rod and the bottom surface of an upper ram connecting hole. Compared with a traditional upper ram connecting mechanism of the internal mixer, the upper ram connecting mechanism of the internal mixer, disclosed by the utility model, has the advantages of simple structure, reliable connection, high safety, long service life, and the like.
Description
Technical field
The utility model relates to the rubber tooling field, is specifically related to a kind of floating weight of banbury mixer bindiny mechanism.
Background technology
Banbury is the equipment that rubber enterprise generally adopts; Floating weight is exerted pressure increasing work efficiency to the sizing material that is refined under the duty, and traditional floating weight of banbury mixer bindiny mechanism structure as shown in Figure 1 is complicated, and piston rod at the snap ring place variation in diameter; Intensity reduces; Banbury down, inevitably has foreign material such as carbon black, oil plant and chemical assistant to enter between stopper rod and the snap ring in working order, and the time has been grown and can produce corrosion to piston rod; Finally cause piston rod to rupture herein, produce floating weight and drop to the serious problems in the banburying chamber.
The utility model content
The purpose of the utility model is to overcome above-mentioned not enough problem, and a kind of floating weight of banbury mixer bindiny mechanism is provided.
The utility model for realizing the technical scheme that above-mentioned purpose adopted is: a kind of floating weight of banbury mixer bindiny mechanism; Comprise piston rod, floating weight; Said floating weight is connected with piston rod through bearing pin; Said bearing pin is inserted in the hole that piston rod is provided with, and the said bearing pin outside is with composite bearing, and bearing pin carries out axial location through shaft end ring; Hole that said piston rod is provided with and the gap between the bearing pin are greater than the gap between piston-rod lower end face and the floating weight connecting hole bottom surface.
The hole that said piston rod is provided with is a slotted eye.
The characteristics of the utility model are: compare with traditional structure have simple in structure, be connected advantages such as reliable, safe and long service life.
Description of drawings
Fig. 1 is a traditional floating weight of banbury mixer bindiny mechanism sketch map;
Fig. 2 is the structural representation of the utility model.
Wherein: 1, piston rod 2, floating weight 3, composite bearing 4, shaft end ring 5, bearing pin.
The specific embodiment
As shown in Figure 2; The utility model comprises piston rod 1, floating weight 2; Said floating weight 2 is provided with oval-shaped hole, and said floating weight 2 is connected with piston rod 1 through bearing pin 5, and said bearing pin 5 is inserted in the slotted eye on the piston rod; The said bearing pin outside is with composite bearing, and bearing pin carries out axial location through shaft end ring; Gap on the said piston rod between slotted eye and the bearing pin is greater than the gap between piston-rod lower end face and the floating weight connecting hole bottom surface.
The above; Be merely the preferable specific embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technical staff who is familiar with the present technique field is equal to replacement or changes according to the technical scheme of the utility model and design thereof in the technical scope that the utility model discloses, and all should be encompassed within the protection domain of the utility model.
