Abstract

The utility model discloses a lower lining fixed structure for cone crusher, which comprises a lower lining and a body, wherein, a flange edge is arranged at the outside of the lower lining end face and is fixed with the body; the upper edge of the flange edge is provided with a plurality of counter bores along the circumference, while the part on the end face of the body corresponding to the counter bores is provided with screws of same number; fasteners are arranged inside the counter bores and the screws for connecting the lower lining and the body. The utility model connects the flange edge on the lower lining and the body through fasteners, and compared with the bolt connection adopted by prior art, the utility model realizes reliable connection and convenient disassembly with just one lower lining being replaced when lower lining needs to be replaced.

Description

Lining fixed structure under the gyratory crusher

Technical field

The utility model relates to a kind of gyratory crusher, the structure that following lining is connected with body in particularly a kind of gyratory crusher.

Background technology

Gyratory crusher is a kind of machinery of broken or operation in small, broken bits in being used for the ore of various hardness or material carried out, and is widely used in departments such as metallurgical mine, building materials, traffic, chemical industry.In the prior art, adopt the junction of the edges of two sheets of paper screw of interference fits to assemble under the gyratory crusher between lining 2 and the body 3, as depicted in figs. 1 and 2, following lining 2 and body 3 are fixed in junction of the edges of two sheets of paper mode with screw 19 at the cover seam crossing of following lining 2 and body 3 end faces with friction tight mode socket.There is following defective in this assembling mode: one, and changing down, lining 2 need heavily bore junction of the edges of two sheets of paper screw 19; Two, junction of the edges of two sheets of paper screw 19 is stressed not enough, usually can't prevent down that lining 2 rotates, and cause thread damage, and thread damage just must be changed screw 19 and following lining 2 simultaneously; Three, assembling is inconvenient.

The utility model content

The technical problems to be solved in the utility model provides lining fixed structure under a kind of gyratory crusher, can make down lining firm fixation on body, and easy accessibility.

For solving the problems of the technologies described above, the lining fixed structure comprises lining, body down under the utility model gyratory crusher, and at following bush end face arranged outside flange, this flange is fixedlyed connected with body.

The flange upper edge circumferentially evenly is provided with a plurality of counterbores, and the screw of equal number is set with the corresponding position of this counterbore on the body end face, in this counterbore and screw, be provided with securing member be connected under lining and body.

The utility model will descend the flange on the lining to be connected with body by securing member, compare with the structure of using the screw junction of the edges of two sheets of paper to be connected in the prior art, it is firm not only to connect, and convenient disassembly, even when lining need be changed down, also only need change a following lining again and get final product.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

The lining fixed structure has designed a kind of following lining 2 of flanged limit 21 under the utility model gyratory crusher, fixedlys connected with body 3 by this flange 21.Circumferentially evenly arrange a plurality of counterbores 22 in these flange 21 upper edges, correspondingly, the screw 32 of equal number is arranged in the relevant position on body 3, adopts hexagon socket head cap screw as connecting with securing member 16 then, by securing member 16 flange 21 is fixedlyed connected with body 3.The quantity of counterbore 22, screw 32 and corresponding bolts can depend on the needs, and is generally 6 or 8.Extremely shown in Figure 6 as Fig. 3.

Above-mentioned securing member 16 can adopt M20 soket head cap screw or hexagon socket head cap screw.Following lining 2 adopts interference fits with cooperating of body 3, instantly after lining 2 is pressed into body 3, fix, because the M20 screw is stressed very big with the soket head cap screw of M20, so lining 2 just is fixed on the body 3 under whole, even under stressed big situation, following lining 2 can not be rotated yet, when lining 2 needs to change instantly, as long as knockout screw, split out down lining 2, the new following lining 2 that changes the outfit gets final product, and dismounting is very convenient.
