Abstract
The invention discloses a miller lining processing technique and relates to a lining, a barrel body and bolts. The processing technique comprises the following steps: spot-welding the lining and the barrel body; marking hole processing lines according to drawing demands; enabling bored holes of the barrel body and the lining to meet the drawing demands; changing a small milling cutter, milling falcon-shaped grooves with width of 6mm on the lining and meeting the drawing demand; grinding the welded points of the barrel body and the lining, installing gaskets and the bolts to fasten the lining and the barrel body. By adopting the lining processing technique, non-coincide of hole centers caused by separate processing of the lining and the barrel body is avoided, and repairing work during assembling is reduced; moreover, the assembling is finished at a time; holes of the lining and the barrel body are bored at the same time, thus time of processing the lining is reduced and processing cost is reduced; the lining and the barrel body have been spot-welded before processing; after the holes are bored, the lining and the barrel body are combined through the bolts; assembling time of the lining is shortened and working efficiency is improved.
Description
Technical field
The present invention relates to a kind of processing technology of grinding machine lining, belong to Machining Technology field.
Background technology
Coal pulverizer is primarily of critical piece compositions such as end cap, cylindrical shell, bearing, lubrications, wherein barrel is the critical piece of coal pulverizer work, also be consumable accessory, in order to prevent the wearing and tearing of cylindrical shell, anti-wearing liner (shown in Fig. 1 a-d) is loaded onto in general meeting in barrel wall, together with lining and cylindrical shell are put together on by bolt hole.Be that finished product does not need to process at the lining of barrel wall left end, the common processing technology of thin lining of right-hand member is all gone out according to the hole drill of drawing requirement by lining by pincers worker, the falcon shape groove of wide 6mm is drawn again by figure requirement, the falcon groove of the installation falcon type bolt on lining is inserted out by slotting machine, this processing technology relates to two step scribing by bench worker operations, drilling machine drilling operating, slotting machine slot operation, lining is evenly distributed with eight altogether at cylinder inboard wall, eight linings all need to process one by one, assembled by pincers worker again after machining, the hole of lining is easily caused not overlap with the hole of cylindrical shell, cause and difficulty is installed, need to repair.
Summary of the invention
Technical problem to be solved by this invention is the defect existed for prior art, provides a kind of new processing technology of grinding machine lining, can not overlap to cause install difficult problem to solve cylindrical shell and bush hole.
For solving this technical problem, the invention provides a kind of grinding machine bush processing technology, relate to lining, cylindrical shell and bolt, concrete technology step is as follows:
1) lining is directly installed on cylindrical shell, by lining and cylindrical shell spot-welded together;
2) the hole machined line of cylindrical shell is drawn in pincers worker according to drawing requirement;
3) hole of boring cylindrical shell and lining reaches drawing requirement;
4) change little milling cutter, loose for the 6mm on lining falcon shape groove is milled out and reaches figure requirement;
5) solder joint of cylindrical shell and lining is ground opening, installing packing ring and bolt is fastening closing.
Described lining is provided with eight, is evenly distributed on cylinder inboard wall.
Beneficial effect: bush processing technology of the present invention avoids the center, hole that processing lining and cylindrical shell cause separately and do not overlap, decrease repair during assembling, and it is once upper alive, the hole of lining and cylindrical shell bores simultaneously, decreases the time of processing lining, reduces processing cost, and lining and cylindrical shell spot-welded together before processing, after boring hole, direct construction bolt carries out handle conjunction, decreases the assembly work of lining, increases work efficiency.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is specifically described.
Figure 2 shows that the assembling schematic diagram of lining of the present invention and cylindrical shell.
The C portion enlarged diagram of accompanying drawing 2 of the present invention shown in Fig. 3.
The present invention relates to lining 1, cylindrical shell 2 and bolt 3, described lining 1 is provided with eight, the structure of lining 1 as shown in Fig. 1 a-d, described α=75 °, concrete technology step is as follows:
1) eight linings 1 are evenly installed to cylindrical shell 2 inwall according to the matching requirements of drawing, by spot-welded together to lining 1 and cylindrical shell 2 inwall;
2) the hole machined line of cylindrical shell 2 is drawn in pincers worker according to drawing requirement;
3) boring cylindrical shell 2 hole circumferentially, because lining 1 and cylindrical shell 2 are spot-welded together, while the hole of boring cylindrical shell 2, the hole on lining 1 is also bored together simultaneously, decreases the time of processing lining 1, reduces processing cost;
4) change little milling cutter, according to drawing loose for the 6mm on lining 1 falcon shape groove 4 milled out and reach figure requirement;
5) grind with the solder joint of lining 1 cylindrical shell 2 and open, bolt 3 penetrates in the hole that lining 1 and cylindrical shell 2 get out, and by installing packing ring and bolt 3 by fastening closing to lining 1 and cylindrical shell 2, decreasing the assembly work of lining 1, accelerating operating efficiency.
Bush processing technology of the present invention avoids the center, hole that processing lining and cylindrical shell cause separately and does not overlap, and decreases repair during assembling, and once upper alive, reduces processing cost, decreases the assembly work of lining, increase work efficiency.
The above-mentioned embodiment of the present invention, just illustrates, is not only, and the change within the scope of the present invention all or equivalent scope of the present invention is all surrounded by the present invention.
