Until recently, this metal and Assembly tool for screwing-unscrewing small fasteners and understand that special needs were not. Every Amateur designer or a mechanic, vehicle enthusiast, having in the Arsenal of his Studio a couple of sets of screwdrivers (under “slot” and by “cross”), they completely and treated. Head of cogs, bolts, screws in various household tools, appliances and even cars of domestic production, too, had, respectively, either slotted or Phillips working the nest.
LET’S DEAL WITH THE SCREWDRIVER
No, of course not with fire, as fire with fire as the saying goes, and… turn away. Because the wedge as the main element included in the design of the unusual wrench proposed Nikolaev innovators. The originality of the tool lies in the fact that in contrast to the known devices there are no grooves, rods, worms, axles. The key is extremely simple, reliable, very easy to use.
They look close to the “classic” scheme: have a body and a fixed jaw, a screw that moves the movable jaw, lugs for attaching to the workplace. But for all its similarity to conventional new grip thanks to the clever solution of their design has acquired much greater opportunities, become universal. The main feature of the original clamping device, developed by Turner M. Babichev, Vitebsk machine-tool plant named after Comintern is movable sponge: it is made in the form of rotary drum. In other details the innovator has made the changes.
For modern engineering and many other sectors of the economy it’s not uncommon for such large structures, in which the Assembly or disassembly of powerful bolting already exempt from the ordinary hand tools or power one working. That’s why the innovators of Novo-Gorkovsky oil refinery created a powerful Electromechanical wrench. It is a two-stage planetary gear associated with seriesname DC motor with a power of 0.9—1.0 kW. The torque transmitted to them at the nut is 825 KGM.
In the “Modeller-designer” has repeatedly published materials on woodworking machines-“circular saw” circular saw and planer, so necessary for the house masters. On this publication have done for a similar machine and I. But when I did, I realized that not everything in it is fine with me. In particular, the mechanism of lifting-lowering of the table. And the device is called the mechanism was only possible with the big stretch. The table was mounted on four studs-the uprights and vertical movement required to turn is to roll as many as eight nuts. And to set the plane of the table parallel to the axis of the plane (and saws) had “by eye”. In the end decided to make another table with more “advanced” mechanism (table) of lifting-lowering.
Improvised creativity are addicted to for a very long time. And in many respects it was promoted by my favorite magazine “modelist-Konstruktor”. Released since 1972. The recommendations and tips magazine has done a lot useful on the farm structures. The biggest of them —the tractor Arkhipova (“M-K” № 1, 1984), Gromov and all-terrain vehicle (“M-K” No. 1 for 1985).
How diverse is pressed in units of parts so numerous and adaptations for wheel — pullers. However, the majority of them operates on the principle of ejection. Well, if the part is pressed into a blind hole? How to extract, for example, the sleeve or the bearing? The original puller for these cases, constructed by the innovator A.V. Yakimenko with the Odessa plant “Stroget-replica”. The principle of it is somewhat reminiscent of some designs of household tailspin.
Rationalization proposal Lyubertsy student of secondary school № 42 of Yuri Furmanov. How to ensure all novice turners cutters? Almost every school workshop this problem exists. The HSS tools quickly become dull and break in inexperienced hands boys, standard tool holders with brazed them on the plates from hard alloys are not suitable for school machines high. The same applies to the most affordable cutters with exchangeable sintered plate (durable, able to withstand the most critical conditions).
