Description

one

The invention relates to carousel machines for machining, for example, grinding flat glass, in particular to a grinding unit of a machine.

Known carousel multi-position machines for machining figured glass, containing rotary spindles, vacuum suction glass holders, a fixed copier and an orienting device in the form of movable stops.

The disadvantage of these machines is the immovability of the copier, the complexity of its design, the difficulty of readjustment of the machine, inaccurate copier processing of glass.

In the proposed carousel machine, these disadvantages are eliminated by the fact that the copier is made by swinging from a drive containing a vacuum chamber with a membrane and a swinging two-arm arm pivotally connected to the membrane.

FIG. 1 shows the machine spindle unit; in fig. 2 - spindle assembly in section along the spindle axis; in fig. 3 - spindle assembly, top view; in fig. 4 shows a section along A-A in FIG. 3

On the rotary table 1 of the machine, a spindle unit 2 is mounted, containing a rotary spindle 3 with a vacuum suction cup 4, a swinging copier 5 with fixed orienting stops 6, bearing pads 7 sec.

figured 8, pins 9 and springs 10.

On the bottom of the spindle, a double-arm lever 11 is strengthened, which is articulated with the hinge 12 with the membrane 13 of the vacuum chamber 14, and the stopper 15 with a copier. The lever swings around axis 16. Washers 17 with a calibrated orifice 18 separate the glass from the vacuum chamber. Last reported to vacuum distributor

machine 19 through the tube 20, the fitting 21 and the channel 22 in the vacuum suction.

Spindle node works as follows.

When serving table 1 spindle assembly 2

it is disconnected from the vacuum chamber 14 to the loading position. At this time, the latter is connected with the atmosphere, the membrane 19 is trimmed, the copier 5 with the stop 6 RISING the spring 10 to a height corresponding to the position of the glass

on the vacuum suction 4, limited by the movement of the lever 11 w limiter 15.

The glass is placed on the vacuum suction device, fixing it on the lugs 6. The vacuum chamber 14 is connected to the vacuum distributor 19. When

In this case, the membrane (5) rises, dragging the lever, which rotates around the axis 16, with the restrictor 15 acts on the copier 5. The latter, turning relative to the arms 8 and the pins 9, lowers and compresses the spring 10.

The lever 11 holds the copier 5 in a horizontal position during the entire glass processing period. The pins 9 hold it from displacing the copier. The glass is secured by the vacuum coming in to the suction cup through the opening 18 of the clamp 17.

At the end of the glass treatment, the vacuum is turned off and the cycle is repeated again.

To change the carbon copy, the limiter is rotated 90 ° on the lever 11, the copier is lifted until the pins 9 exit from its openings and removed from the beams 8. The new copier is installed in the reverse order.

Subject invention

A glass carousel for machining glass, for example, grinding, comprising a rotary spindle with a vacuum glass holder, a copier with orienting stops and a drive, characterized in that, in order to improve machining accuracy, the machine copier is made spring-loaded, swinging from a drive consisting of a vacuum chambers with a diaphragm and a swinging two-arm lever pivotally connected to it.
