Description

For the cutting of globoidal screws on non-special machines, various designs of devices are used, in particular, devices made in the form of a turntable with a case head (gearbox) equipped with a spindle are known. The latter rotates the workpiece, kinematically connected through interchangeable gears with the rotation of the plate.

However, such devices do not provide the possibility of cutting globoidal screws on non-special machines using cutting tools: a cutter, a disk cutter and an abrasive wheel.

The described device allows the cutting of a globoidal screw on non-special machines with conventional cutting tools: cutters or a disk cutter, or an exemplary circle. To accomplish this goal, the rotary table of the machine is equipped with a copier ruler, which interacts with a poop mounted on the rotary tool head of the machine, which, when the machine rotates, rotates the tool according to the variable angle of elevation of the turns of the worm being cut.

The drawing shows a part of the machine with adaptive HEm.

The device consists of an installed pa turntable / machine plate 2 with a universal dividing holo 3 fixed on it. The latter has a horizontally located spindle / and 4, which is driven by an electric motor -).

The subdivision head 3 is kinematically connected with the help of pn shank joint 6 with the rotation of the table / and the plate 2.

The tool 8, for example, a cutter, is fixed perpendicular to the axis of the spindle on the tool head 7 of the machine tool.

When cutting a screw with a disk tool, such as a disk cutter or abrasive wheel, the tool is told to swing, which corresponds to the variable angle of elevation of the turns of the screw being cut. For this purpose, a copier is installed on plate 2

In the process of operation of an electric motor, 5 is driven by 1C) a1satel: 1; l: the movement of the spindle 4 delyevnyh head 3 together with the dill on it blank 11.

At the same time, through the interchangeable gears 6, the plate 2 is rotated together with the table around its vertical axis with the bearing head: gage head 3.

If cutting the screw on a milling machine - burn .4 :: iTa / ihHOM OR vertically, feed to the depth of penetration of the cutting tool using a longitudinal or transverse machine pit of the machine tool or on the indicator.

If the EU, 1, and the same threading of the screw is done by whispering, then feed to |. The incision of the tool is made by longitudinal movement of the machine ram along the indicator mounted on the machine bed.

When working with a disk tool, for example, a disk cutter;: l; .1 with an abrasive wheel, in the process of rotating the spindle 4 s-workpiece // and turning the table / together with the last one, the ruler 9 rotates, which with its curvilinear surface informs the roller 10 rocking. As a result of a combination of rotation, workpiece and swinging movement of the disk tool, 1t slicing of the worm, the surface of which is / loboid, occurs.
