Abstract
The utility model relates to a ball mill machine, particularly a wear-resistant lining plate for ball mills. The inside of the utility model is provided with a bottom groove which can place the tail part of a fastener and a vertical groove which can make the head of the fastener extended. Cross grooves which can make the tail part of the fastener put in the bottom groove are arranged on one ends of the vertical groove and the bottom groove. The width of the vertical groove is smaller than the width of the bottom groove. The utility model has the advantages of long service life, reasonable structure, convenient operation, etc.
Description
The utility model relates to ball milling machinery, the abrasion-proof backing block on specifically a kind of ball mill.
Existing ball grinding machine lining board all leaves to install uses screw, and screw forms stress concentration point in the liner plate manufacture process, weakened the ability to bear of liner plate impact power.This design is low to hardness, potassium steel of good toughness, low-alloy steel etc. almost are inessential, and be the main cause that possible cause the workpiece fracture failure to the brittle metal high-abrasive material of high rigidity, low toughness, in actual applications, the inefficacy of antifriction cast iron workpiece, exhausted major part produces by hole or stress concentration point.
The purpose of this utility model is a design ball grinding machine lining board a kind of rational in infrastructure, easy to use, problem such as concentrates to avoid liner plate bigger stress to occur.
Its main technical schemes is in liner plate inside the kerve that can place the securing member afterbody to be arranged, and the vertical slot that can allow fastener head stretch out, end at vertical slot and kerve has the translot that can allow the securing member afterbody put into kerve, and the width of vertical slot is less than the width of kerve; The shape of kerve can be rectangle or swallow-tail form, the corresponding fasteners afterbody also is the rectangle or the swallow-tail form that can cooperatively interact with the rectangle or the swallow-tail form of kerve.
The utility model has the advantages that owing to adopt the mounting groove structure that constitutes by vertical slot and kerve, the problem of stress concentration that has been produced when having avoided the screw of original use perforation, thereby improved intensity and service life.Secondly, adopt this mounting groove structure after, during use, only need the afterbody of relevant securing members such as bolt is embedded in the kerve, will get final product in the hole on the head alignment with the ball grinding mill barrel of bolt again, owing to kerve and vertical slot all have certain-length.Therefore, on time, the adjustment distance of bolt in groove is bigger, thus made things convenient for liner plate accurately the location with install, and, after the afterbody of bolt embeds in the mounting groove, or not do not drop easily as original through screw, also help handled easily.
Fig. 1 is a user mode degree of the present utility model
Fig. 2 is the B-B view of Fig. 3
Fig. 3 is that the A of Fig. 2 is to figure
As shown in the figure, the kerve 7 that can place securing member afterbody 5 is arranged in liner plate 6 inside, and the vertical slot 3 that can allow fastener head 2 stretch out, end at vertical slot 3 and kerve 7 has the translot 8 that can allow securing member afterbody 5 put into kerve 7, the width of vertical slot 3 is less than the width of kerve 7, and the section configuration of kerve 7 is rectangular.
During use, in the groove of each piece liner plate 3, place bolt, and the nut end (being securing member afterbody 5) on the bolt is embedded in the kerve of liner plate, its head (being fastener head 2) stretches out outside the vertical slot, then, the liner plate block-by-block is put into the inwall of ball mill barrel 4, and bolt head is stretched out the screw of barrel wall, again with nut 1 fastening make whole cylinder inboard wall all row full after, can use ball mill.
