Abstract
The invention discloses an improved end liner plate which is mounted at the inner side of an end cover of a barrel body of a ball mill. The improved end liner plate comprises a liner plate body; a concave arc-shaped surface is arranged at the upper end of the liner plate body while a convex arc-shaped surface is arranged at the lower end of the liner plate body; the concave arc-shaped surface and the convex arc-shaped surface share one center line; extending surfaces extending to the center line are arranged at the left end and the right end of the liner plate body; the left ends and the right ends of the concave arc-shaped surface and the convex arc-shaped surface are connected through the extending surfaces; a pair of bosses distributed around the center line is arranged at the front end surface of the liner plate body; a pair of circular bosses corresponding to the bosses on the front end surface is arranged on the rear end surface of the liner plate body; stepped holes which pass through the circular bosses and the bosses are formed in the centers of the circular bosses.
Description
Technical field
The present invention relates to a kind of modified aside-liner.
Background technology
The coarse grinding cabin aside-liner of ball mill often comes off, a phenomenon of rupture, the aside-liner of a few circle especially.Be that bolt strained concentrated damage by fastening end liner plate causes through looking into, adding aside-liner is single bolted, stops mill inspection at every turn, to change aside-liner cumbersome.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, provides a kind of modified aside-liner.
The technical solution adopted for the present invention to solve the technical problems is: a kind of modified aside-liner, be arranged on inside ball mill barrel end cap, comprise body, body upper end has concaved circular cambered surface, body lower end has convex arc surface, concaved circular cambered surface and convex arc surface have same center line, body is left, right-hand member has the extended surface extended to center line respectively, a left side for concaved circular cambered surface and convex arc surface, right-hand member is connected respectively by extended surface, the front end face of body has a pair boss around center line distribution, the rear end face of body has a pair circular bosses corresponding with front end face boss, circular bosses center is provided with the stepped hole running through circular bosses and boss.
Described stepped hole comprises the diameter holes of boss side and the hole, large footpath of circular bosses side.
The invention has the beneficial effects as follows: the present invention adopts two bolt to install, and adds guard circle, thus extends the life-span of this aside-liner, reduce the production cost of enterprise around installing hole.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention;
Fig. 2 is the left view of Fig. 1.
In figure: 1. concaved circular cambered surface; 2. convex arc surface; 3. extended surface; 4. front end face; 5. boss; 6. rear end face; 7. circular bosses; 8. stepped hole.
Detailed description of the invention
The present invention is further illustrated with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As Fig. 1, a kind of modified aside-liner shown in 2, be arranged on inside ball mill barrel end cap, comprise body, body upper end has concaved circular cambered surface 1, body lower end has convex arc surface 2, concaved circular cambered surface 1 and convex arc surface 2 have same center line, body is left, right-hand member has the extended surface 3 extended to center line respectively, a left side for concaved circular cambered surface 1 and convex arc surface 2, right-hand member is connected respectively by extended surface 3, the front end face 4 of body has a pair boss 5 around center line distribution, the rear end face 6 of body has a pair circular bosses 7 corresponding with front end face 4 boss 5, circular bosses 7 center is provided with the stepped hole 8 running through circular bosses 7 and boss 5, stepped hole 8 comprises the diameter holes of boss 5 side and the hole, large footpath of circular bosses 7 side, adopt bolt this aside-liner can be installed to inside ball mill barrel end cap by stepped hole 8, described front end face 4 edge also has several (not shown) such as high boss such as grade for supporting this aside-liner.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
