Abstract
The utility model relates to a heavy rotary turning tool which belongs to a matching part of machine tool industry. A detachable turning tool for aiming at the defects of large turning tool consumption, troublesome operation, single main deflection angle, limitation of lathe potentiality, etc. in the process of processing caused by that the existing lathe uses a welding tool bar or few rotary turning tools. The utility model is composed of a cutter body and a cutter blade. The utility model is characterized in that the cutter blade is fixed on the cutter body by an eccentric shaft; the cutter blade is fixed on a pressing block by a screw and a pin, so that the cutter blade and the cutter body are firmly assembled into a whole. The utility model has the advantages of simple assembly and clamping of the cutter blade, production consumption reduction and working condition improvement. The utility model has a wide application prospect in the rough machining operation of large and medium-sized lathes.
Description
The heavy indexable turning tool of the utility model belongs to a kind of matching component of machine tool industry.
At present, big-and-middle-sized lathe generally adopts the welding knife bar, and shortcoming is in the machined into process, and the lathe tool amount of feeding and the depth of cut are little, equipment potential can't be brought into play, simultaneously because cutter hub and blade can not be rolled over imperially, blade is scrapped cutter hub and is destroyed together, wastes bigger, the large-scale vertical lathe was changed and is scrapped 5～6 of brazed carbide turning tools in every month, operating personnel will roll over the knife bar of driving about 6 kilogram weights at every turn, and labour intensity is big, and bother very much; Though indivedual manufacturer production indexable turning tools such as Yangpu, Shanghai tools factory have only a kind of model, and because the project organization restriction, it is cumbersome to be installed, and blade can not fully be utilized.
The purpose of this utility model is at above-mentioned defective, has designed the employing of a kind of cutter hub and blade and can roll over imperial structure, and breaks down is only changed blade; Blade is installed rational in infrastructure, the bilateral blade can be fully utilized, simultaneously, having designed tool cutting edge angle is the serial lathe tool of the various models at 45 °, 75 °, 90 ° angles, therefore can replace traditional lathe tool that big-and-middle-sized lathe now adopts widely, reach to reduce and produce the purpose that consumes, increases benefit, improves working conditions.
The heavy indexable turning tool of the utility model, a kind of matching component that belongs to machine tool industry, it is by cutter hub (1), blade (5) is formed, it is characterized in that blade (5) is provided with blade-a(10) and blade-b(11), blade (5) is installed on the cutter hub (1) after being enclosed within eccentric shaft (6), between blade (5) bottom and cutter hub (1) installed surface bed plate pad (8) is installed, between blade (5) one sides and cutter hub (1) installed surface side tool pad (9) is installed, blade (5) is fastened on the cutter hub (1) by briquetting (4), and briquetting (4) is fixed on the cutter hub (1) by gong nail (2) and pin (3).
The utility model is compared with the regular turning tool that existing big-and-middle-sized lathe is adopted, the advantage that has be simple in structure, easy to operate, improved working condition; Blade can fully be utilized; The product specification seriation; Blade is scrapped and is changed blade again and get final product; Cutter hub is contact workpiece not, and bed plate pad and side tool pad protection cutter hub can reach more than 5 years cutter hub service life; Reduce consumption costs thereby can save lathe tool in a large number with steel, increase economic benefit effectively.In the heavy indexable turning tool of homogeneous structure, 6 kinds of tool cutting edge angles (7) are arranged, tool cutting edge angle (7) is the lathe tool of 45, has designed models such as PGSNR4032R42 and PGSNL4032R42; The lathe tool at 75 ° of angles of tool cutting edge angle has designed models such as PGRNR4032R42 and PGRNL4032R42; The lathe tool at 90 ° of angles of tool cutting edge angle has designed the serial lathe tool of models such as RGFNR4032R29 and PGFNL4032R29.In big-and-middle-sized lathe roughing process, have wide practical use.
Description of drawings:
Fig. 1, the three-dimensional installation diagram of heavy indexable turning tool, wherein: (1) cutter hub, (2) gong nail, (3) pin, (4) briquetting, (5) blade, (6) eccentric shaft, (7) tool cutting edge angle, (8) bed plate pad, (9) side tool pad, (10) blade-a, (11) blade-b.
Operation of accompanying drawings lathe tool and action mechanism.When assembling heavy indexable turning tool, earlier bed plate pad (8) is fastened on the cutter hub by the gong nail, eccentric shaft (6) and side tool pad (9) are bound on cutter hub (1) by gong, blade (5) is installed on the eccentric shaft (6) again, and blade (5) promptly tentatively is installed on the cutter hub (1); Briquetting (4) is fixed on the cutter hub (1) by gong nail (2) and pin (3); Briquetting (4) other end holds out against blade (5) by pin (3), makes blade (5) by eccentric shaft (6), and blade (5) is attached on bed plate pad (8) and the side tool pad (9) securely, and assembling is promptly finished.
When the blade of blade (5)-when a(10) being in the lathe tool outside, utilize the turning processing work of blade-a(10), when blade-a scraps, turn on gong nail (2) and side tool pad gong and follow closely, lift briquetting (4), can take off blade (5) from eccentric shaft (6); When needs use the processing work of blade-b(11), behind rotating blade (5) orientation, blade (5) is installed on the eccentric shaft (6), be close to bed plate pad (8) and side tool pad (9) and make briquetting (4) one ends hold out against blade (5) again to tighten side tool pad and gong nail (2), at this moment, the blade of blade (5)-b(11), promptly be in the outside of cutter hub (1), during processing work, blade-b(11) can operate, lathe tool blade (5) transposition is installed and is promptly finished.
When more renewing blade, its operation sequence is; At first turn on gong nail (2), loosening side tool pad gong nail lifts briquetting (4) again, can take off from eccentric shaft (6) and scrap blade (5), more renews blade again.
In the machined into workpiece process, workpiece processing resistance is by blade (5), bed plate pad (8) and side tool pad (9) affact on the cutter hub (1), turner constantly raises blade (5) temperature simultaneously, this high temperature passes to gong nail (2), make gong nail (2) expanded by heating, gong nail (2) length increases, make briquetting (4) have gong nail Kong Yiduan to produce the power of direction to cutter hub (1) outside, pin (3) is as the balance pivot of briquetting (4), the end that briquetting (4) is contacted with blade (5), generation presses closer the inboard power of blade (5) trend cutter hub (1), under the effect of processing work resistance and thermal expansion force, blade (5) is gone up fixing more firm at cutter hub (1).
The heavy indexable turning tool PGFNR5040S42 of the utility model specification lathe tool, after cutter hub (1) and blade (5) install, processing work on four meters vertical lathes, workpiece material is a 45# cast steel, tool cutting edge angle (7) is respectively 45 °, 90 ° angles, cutting speed per minute 40～80m, the amount of feeding: revolution 1mm, depth of cut 15-20mm, operation is normal.Change blade (5) and only need 1 minute at every turn, improve work efficiency more than 1 times.
