Description

The invention relates to the field of engineering technology.

A known machine for controlling and sorting cylindrical parts by size and shape, contains a loading hopper, a feeder for feeding parts to a measuring position, a measuring unit with contactless meters and a sorting unit.

In order to improve the measurement accuracy in the proposed automaton, the measuring unit includes a pre-measurement station with one meter, a final measurement station made in the form of a turret and a number of gauges mounted on it, and a control circuit for turning the turret.

The drawing shows the kinematic scheme of the proposed machine.

The proposed machine consists of a loading hopper 1, a feeder 2 for supplying parts to a transporting disk 3 having an intermittent movement, six positions for placing parts are placed at the 1 {outlet.

The operation of the mechanisms is controlled by a camshaft 4 receiving rotation from an electric motor 5 through a gear 6.

On the shaft 4 mounted cams 7-10. Parts are controlled by a measuring unit at two positions of the disk 3, one of which

It is serviced by a preliminary measurement station 11 of this unit using a pneumatic plug 12, which can be moved vertically from the lever 13, and another by the final measurement station 14 of this unit with pneumatic plugs 15 mounted on a turret 16, the choice of which is determined by the measurement result at the previous position . The total measuring range of the pneumatic plugs of the final measurement station is equal to the measuring range of the pneumatic plug of the preliminary measuring station. The turret is reversed from the reversing motor 17 through the gear train 18 and 19. The station 14 is vertically moved through the system of levers 20 from the cam 8. The rotational drive of the monitored parts at the position of the 1 stage contains the belt Transmission 21 and the electric motor 22. The sorting device of the machine is made in the form of a tube 23 with nozzles, having the ability to turn from the electric motor 24 through a gear 25. Electromagnetic clutch 26 and a belt drive 27. Inside the tube 23 is located the rod 28 of the distribution a separating mechanism connected to one of the ends of the two shoulders lever 29. The rod 28 has a vertical movement from the electromagnets 30. The sorting device contains measles 31, under which electromagnets 32 are located, the number of which corresponds to the number of sorting groups in each section 33.

To remove parts that have a hole-shaped defect, there are two grading devices installed after the measuring stations 11 and 14, respectively, which direct the rejection parts into the trays 34 and 35.

The disassembly device mounted behind station 11 consists of a lever 36 connected through a rail 37, a gear wheel 38 and a lever 39 with a cam 10, and a latch 40 connected to an electromagnet 41. The disassembly device installed behind station 14 differs from that considered by the fact that the lever 42 is stably turned away from the cam 9.

The proposed machine works as follows.

The controlled parts from the hopper 1 are fed through the filler 2 to the transorting disk 3 having intermittent rotation. A pneumatic plug 12 of the station 11 of the preliminary measurement through the system of levers 13 from the cam 7 of the camshaft 4 enters the hole of the rotating part. The part is rotated from the motor 22 through a belt drive 21,

According to the measurement results at this position, commands are given to turn the turret 16 to set the pneumatic plug of the corresponding measuring range and to set the shaker 28 to the appropriate position. When the part is installed at the station 14 of the final measurement, the latter, firing down, inserts the plug 15 into the orifice of the rotating part. During the downward movement of the pneumatic tubes, the shape of the hole is controlled, and when it moves upward, the hole diameter is sorted into size groups.

The signal of the appropriate sorting group is fed to one of the electromagnets

32.When the core 31 is above the electromagnet 32, the electromagnet is triggered.

coupling 26; rotating tube 23 stops against the corresponding tray section

33.When the part is transferred to the next position, the lever 36 feeds it into the tube 23. When a hole is detected according to the shape by the preliminary measuring station 11, the part is removed to the next position in the tray 34, The reject command is sent to the electromagnet 41, releasing latch 40 rack 37, and the lever 36,

turning against the gear wheel 38, it removes the defective part from the transporting disk 3,

If a fault is detected by station 14, the electromagnet 41 is de-energized, the latch 40

hooks on the toothed rack 37, in which the part is not removed from the disk 3, but is transferred to the last position where the lever 42 is removed to the tray 35,
