Description

one

The invention relates to devices for testing products in mechanical engineering and concerns automatic machines for controlling and sorting parts according to linear dimensions.

Automatic machines for controlling parts by linear dimensions are known, containing measuring stations, an electromechanical memory device with a drum mounted on its shaft, carrying memory cells, sensing signals from measuring stations, a sorter controlled by a memory device, a disk conveyor rotated about its axis synchronously with the shaft memory device and designed to transfer parts from the measuring stations to the sorter, a drive with a cam camshaft and a lever rip mechanisms camshaft communication with the storage device.

The aim of the invention is to increase the reliability of the machine in operation.

This is achieved by the fact that the drum is mounted on the shaft of the memory device with the possibility of movement in the axial direction, and the sorter is designed as a rod spring-loaded in the axial direction with a stop interacting directly with the corresponding memory cell.

FIG. 1 shows the general scheme of the proposed automaton; in fig. 2 - kinematic diagram of the automaton.

The controlled part 1 is moved by a disk conveyor 2 rigidly fixed on the shaft 3. A Maltese cross 4 is fixed on the same shaft. A Maltese gear leash 5 is mounted on a cam camshaft 6 of the automatic drive.

At position I, the parts are loaded into the machine, at position P of the measuring station - control. Positions 111 and IV are sorting. The machine contains electromechanical

a device (not shown in the drawing) with a multifaceted drum 7 mounted on its shaft 3, the number of faces of which is equal to the number of positions of the automaton. The drum is connected through an intermediate link mechanism 8

with a fist 9, rigidly mounted on the camshaft 6 of the machine. On the edges of the drum, there are non-convertible two-lever levers 10, which are memory cells of the memory device.

The electromagnet 11 with the lever 12 is rigidly fixed on the frame on the measuring position II of the machine. The sorter (not shown) is made in the form of a rod 13 with a pore 14. The cam 15 is rigidly fixed on the frame in the interval between the positions I and II of the automaton.

The camshaft 6 receives rotation from the common drive of the machine (not shown in the diagram). The leash 5 of the Maltese mechanism with the help of the Maltese cross 4 turns the disk tranorter 2 by one step in each cycle of the machine.

If the item checked at position II of the measuring station must be zydsh:: P1 POSITION, electrioMariiiT 11 is triggered and sets lever 12 opposite lever 10. In the automaton cycle of operation of the machine, the lever 12 moves lever 10 to the second position (for the diagram is shown by a dotted line).

In the next cycle of operation of the machine, when the checked part and the corresponding toggle lever move to it when the disk conveyor is rotated to position III, when the drum moves forward, the lever 10 engages the stop 14 and the rod 13 pushes the part out of the disk conveyor slot to the sorting tray III.

If the item checked at position II is to be issued from the sorting position IV, the electromagnet 11 in this cycle does not work, and the lever 10 remains when the drum is moving forward in the initial position.

When turning in the next cycle of the drum together with the transport disk, the lever 10 takes a position in front of the stop 14, and

as the drum moves forward, the rod 13 remains stationary. The part remains in the slot of the disk conveyor 2 and passes in the next cycle to position IV, where it can be discharged into the tray either by its own weight or by a rod moving rigidly from the cam in each cycle (not shown in the diagram).
