Abstract
The utility model discloses a clamping device of a mill cylinder lining board. The clamping device of the mill cylinder lining board comprises a cylinder lining board bolt, a base plate, a lining board, a rubber flat mat, a sealing washer and a nut. The clamping device is characterized in that the base plate is welded at the outer side of the cylinder and drills a lining board bolt hole together with the cylinder; a counter bore of which the outer diameter is greater than that of the sealing washer is processed at the end face of the outer side; the rubber flat mat is put inside the counter bore; an inner hole of the rubber flat mat is tightly matched with the cylinder lining board bolt; the sealing washer with a step hole is arranged on the inner hole; the step hole of the sealing washer is slightly greater than the outer diameter of the rubber flat mat; the depth of the step hole is smaller than the thickness of the rubber flat mat; the rubber flat mat is contained; and the nut is pressed on the sealing washer. The clamping device has the advantages that the nut is screwed when the cylinder lining board is clamped; and the rubber flat mat is pressed by pressing the sealing washer. The rubber has elasticity; the end face of the entire sealing washer is even in stress, and elastic deformation is generated after the sealing washer is pressed, so that the sealing of the cylinder lining plate bolt is well achieved; and the situation that the cylinder lining plate bolt does not leak slurry is ensured.
Description
Technical field
The utility model relates to a kind of fastener, relates in particular to a kind of fastener of the grinding mill barrel liner plate of using for mine, building material industry.
Background technology
Present known grinding mill barrel liner plate fixedly be to compress the spheric washer and the sphere rubber blanket that are contained in the cylindrical shell outside by lining-plate bolt by nut to carry out fastening.Because the cylindrical shell outside is circular arc, the discontinuity of sphere rubber blanket, so sealing is undesirable, the situation of spillage often occurs, and also the sphere rubber blanket also damages by pressure easily.
Summary of the invention
The purpose of this utility model is to provide a kind of fastener of grinding mill barrel liner plate, overcomes the shortcoming of the easy spillage in former shell liner bolted place.
A kind of fastener of grinding mill barrel liner plate, comprise the shell liner bolt, backing plate, liner plate, rubbery flat gasket, seal washer and nut, it is characterized in that: welding with backing is in the cylindrical shell outside, get out the lining-plate bolt hole together with cylindrical shell, and the side end face processes the counterbore bigger than seal washer external diameter outside, rubbery flat gasket is placed in this counterbore, the endoporus of rubbery flat gasket and shell liner bolt are tight fit, seal washer with stepped hole is housed on it, the stepped hole of sealing packing ring is more bigger than the external diameter of rubbery flat gasket, the thickness of depth ratio rubbery flat gasket is little, and rubbery flat gasket is contained, and nut then is pressed on the seal washer.
The utility model has the advantages that when fastening shell liner, fastening nut, thus compress rubbery flat gasket by compressing seal washer.Because rubber is flexible, and be that the end face of whole packing ring is evenly stressed, produce strain behind the pressurized, thereby realized the sealing at shell liner bolt place well, guaranteed not spillage of shell liner bolt place.
Description of drawings
Fig. 1 is structural representation of the present utility model;
1. cylindrical shell, 2. liner plate, 3. backing plate, 4. shell liner bolt, 5. rubbery flat gasket, 6. seal washer, 7. nut.
The specific embodiment
Now 1 the utility model is described in further detail by reference to the accompanying drawings:
As shown in drawings, a kind of fastener of grinding mill barrel liner plate, comprise shell liner bolt 4, backing plate 3, liner plate 2, rubbery flat gasket 5, seal washer 6 and nut 7, backing plate 3 is welded in the outside of cylindrical shell 1, process bolt hole together with cylindrical shell 1, and outside end face processes the counterbore bigger than seal washer external diameter, rubbery flat gasket 5 is put in this counterbore, seal washer 6 is installed on it, be processed with more bigger than external diameter rubbery flat gasket 5 on the seal washer 6, the stepped hole that the thickness of depth ratio rubbery flat gasket is little, this stepped hole contains rubbery flat gasket.Nut 7 is pressed on the seal washer 6.When nut 7 tension shell liner bolts 4, seal washer 6 and rubbery flat gasket 5 are all compacted, because rubber is flexible, and rubbery flat gasket 5 be that end face is evenly stressed, so adopts rubbery flat gasket 5 can realize the sealing at shell liner bolt hole place well.
Above content be in conjunction with concrete preferred embodiment to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field; under the prerequisite that does not break away from the utility model design, make some alternative or obvious modification that are equal to; and performance or purposes are identical, then should be considered as belonging to the protection domain that claims that the utility model submits to are determined.
