Abstract

The invention relates to the control of linear dimensions in mechanical engineering and allows to increase the accuracy of control and reliability in operation. The machine contains a loading device 2, a transporting disk 3 with sockets on the periphery, measuring devices 4 and 5 with a base pad 6, loading 7 and sorting 8 devices. The inserts are individually fed into the slots of the transporting disk 3. In the area of the measuring device, the insert is fed into the base pad 6 with the aid of a lifting table, on which the stop is fixed. The loading device through the slider interacts with the liner, orienting it in the angular direction. After measuring the dimensions, the liner is transferred to the sorting device 8. 2 p.

Description

This invention relates to linear dimensions control in mechanical engineering.

The purpose of the invention is to improve the accuracy of control and reliability in operation.

Fig 1 shows an automatic machine, a general view; figure 2 is the same, top view; on fig.Z - section aa in figure 2; figure 1 - section bB in fig.Z; figure 5 is a view In fig.Z; figure 6 - section GG in figure 2; figure 7 - section dd in figure 6.

The machine consists of a frame 1, a boot device 2 with a tilter, a transporting disk 3, measuring devices 4 and 5, a base cushion 6 with a fixed stop, loading 7 and sorting 8 devices, a software device 9 installed on the camshaft of the automatic drive, and an electronic unit ten.

The transporting disk 3 is placed under the base cushion 6 and has on its periphery sockets in which fixed stops 11 are embedded for orienting the inserts 12 when they are fed into the base cushion b.

In the clamping cushion 6 there is a hole in which the ejector 13 is installed. In the bed 1 there is a spring-loaded lift table 14 with a visor, the axis of which coincides with the axis of the clamping cushion 6 and the axis of the transporting disk slot 3, which is necessary to return the liners 12 of the clamping cushion 6 into transport disk 3.

The loading device 7 contains a movable slide 15, pivotally connected via a yoke 16 with a beam 17, one end of which is pivotally connected with a lever 18 fixed on the frame 1, and the other end with one shoulder of the double-arm lever 19, the other shoulder of which through t gu 20 pivots connected with movably suspended load 21 mounted in guide 22. The lever device 7 is kinematically connected with the fist 23 of the automatic drive,

Mobile pushers 24 are mounted in the conveying disc 3, which are in contact with the inner surface of the circular cam 25, having a slot into which the movable stop lever 26 is operable. Between the transporting disk 3 and the sorting device 8 there is a support line 27. Along which a chain with drivers 28 is installed.

The machine works as follows.

Inserts in 12 piles are stacked in a vertical magazine. Periodically using a crank mechanism

The liners 12 are moved from the magazine to the slots of the transporting disk 3. In this case, resting against the fixed support 11, the liner 12 in the slot of the disk 3 unfolds and occupies an unfolded position (Fig. 5). In this position, the liner 12 in the next cycle when turning the transporting disk 3 is fed to the lifting table 14, at the moment of lifting which the liner 12 is loaded into the pillow 6. In this case, the stop side of the liner 12 enters the pillow 6 and is positioned with a certain clearance Z with respect to the fixed stop, ensuring unhindered

liner entry into basing pad.

After installation of the liner 12 into the clamping cushion 6, the loading device operates, ensuring the constancy

clamping clamped force. At this time, the contact of the cam 23 of the automaton with the double-arm lever 19 is interrupted, and the weight of the movable load 21 through the system of hinged joints 16 and 20, of the arms

18 and 19 and the rocker arms 17, the force is transmitted to the movable slider 15, which presses the liner 12 against the stop of the clamping cushion 6. At this moment, the height of the liners on the measuring device 4 and the control of the parallel joints on the measuring device 5 are monitored.

After measurement, the slider 15 departs from the liner 12 and the pusher 13 pushes the liner onto the lifting table 14, which

starts lowering and using a visor returns the insert to the corresponding slot of the transporting disk 3. The latter makes the next turn and moves the insert to the discharge area to

sorting device 8.
