CS200641B1 - Universal tailstock of the machine tools - Google Patents

Description

The invention relates to a universal tailstock for machine tools, in particular center lathes.

The tailstocks of machine tools used so far are mechanically or hydraulically controlled. A common disadvantage of using one or the other type of tailstock is that it can only be used for certain operations. This disadvantage is overcome by the universal tailstock according to the invention

that allows meohanioky controlled tailstock in about 5 minutes to convert to hydraulic control and non-mechanical.

A particular embodiment of the universal tailstock according to the invention is shown in the accompanying drawings, in which Fig. 1 is a view of a mechanically operated tailstock.

3 is a view of a tailstock according to the invention, and FIGS. 3 and 4 show the mounting of the control hydraulic unit on the machine tool bed.

In a particular embodiment, the universal tailstock consists of a body 1, a tailstock quill 2, a handwheel g, a birth bolt 4, a flange g, bolts 6, plugs J, bolts 8, a flange g, bolts 10, an adjustable bolt 11 of a clamping plate 12, nuts 13 the hydraulic cylinder 14 of the high pressure hose 18, the pneumatic-hydraulic multiplier 16, the screws 17 of the bracket 18, the air pressure hose 18, the control levers 20, the clamping plates 21 and the clamping plates 22, the universal tailstock operation is as follows:

A0 200 641

200 841

When changing from mechanical to hydraulic, the plugs J are removed, the screws 6 are loosened and the guide screw 6 is removed by the knob 2 and the flange 2 is removed at the same time »

Screws 8 are screwed into the tailstock body 1, the nuts 13 are tightened and screw 10 flange 2 is screwed to the tailstock quill 2 ·

A clamping plate 12 is mounted between the screws 8 in which a hydraulic cylinder with an adjustable screw 11 is mounted. A high pressure hadioe 15 is connected to the hydraulic cylinder 14. The other end of the high pressure hadioe 15 is connected to the pneumatic-hydraulic multiplier 16. The pneumatic-hydraulic multiplier 16 is used as a source of pressure oil up to o

200 kp / cm. The multiplier 16 is fixed by screws 17 on the bracket 18. The bracket 18 is fixed by a clamping loop 21 and a clamping plate 22 to the machine tool bed 23.

Using the lever 20, the hydraulic cylinder 14 is connected via a high-pressure hose to a pressure oil source via a pneumatic-hydraulic multiplier 16. In this multi2 transporter 16, the output pressure can be continuously regulated up to 200 kp / cm by screw 25. The pressure gauge 24 shows the required pressure.

When the lever 20 is positioned to the right, the tailstock quill 2 moves to the machine tool spindle and vice versa.

• '

To change the tailstock from hydraulic to mechanical, follow these steps:

Slacken the nuts and unscrew the screws 10, 8 and set off the pneumatic-hydraulic clamping device. The guide screw 6 is screwed into the tailstock quill 2 and the flange 2 is fastened with screws 6 · The protective plug 2 is attached to it · The tailstock is thus converted to meohanic operation.

Using the universal tailstock combines all the advantages of meohanlolo clamping with hydraulic, ie the possibility of regulation and precise control of the size of the clamping force, increased safety and the possibility of completely safe use of tooth carriers. The universal tailstock can be advantageously used wherever it is not worth buying a expensive program or numerically controlled machine for capacity reasons. It enables rapid re-adjustment of the machine to efficiently machine both shaft work using tooth carriers and copying equipment, as well as perform drilling operations, trimming and more. The mechanical tailstock can be additionally adjusted and supplemented by all users of the mentioned machines.
