The invention is related to techno-technology 12 to the co-op of the op-mum o p 5 c, which is not the case for you

equipment for the manufacture of magnetic circuits of electrical machines and can be used in the electrical and instrument-making industry.

The purpose of the invention is to improve dosing accuracy and increase productivity.

The drawing shows schematically a device for metering magnetic core sheets.

A device for metering sheets of magnetic circuits of electric machines contains a separate drive 1 and a pressing rod 2 rigidly connected to the working plate 3, pressing the magnetic core packet 4, which is mounted in the assembly tool 5 on the base 6.

Pressing the No. 1 rod 2 through the compensating spring 7 is mounted movably in the arm 8 of the manipulator 9. The working plate 3 is made in the form of a gripper (for example, with vacuum suction cups). The working plate 3 through the lever 10, hinged on the support 11, is in contact with an electric contact two-limit sensor 12 (such as the model 233 of the Caliber plant, which has two contact groups), which is electrically connected through the control unit 13 to the presses of the pressing rod, gripper and manipulator. The device also contains a magazine 14 sheets of magnetic circuits.

The device works as follows.

In the initial position, the pressing rod 2 with the working plate 3 is located above the package 4 of the magnetic core mounted on the assembly tool 5. The beginning of the device operation cycle is the vertical movement of the arm 8 of the manipulator 9 downwards. The working plate 3 is lowered onto the stack 4 of the magnetic circuit, the drive 1 is turned on and, acting on the pressing rod 2 with the working plate 3, provides the necessary crimping force. The height of the stack 4 of the magnetic circuit is determined by the distance between the base of the assembly tool 5 and the supporting surface of the working plate 3. During the crimping operation, the working plate 3 in downward contact with the lever 10 and unfolds it.

while the movable contacts of the sensor 12 are moving relatively stationary. At the end of the crimping operation, in the event that the height of the stack 4 of the magnetic circuit deviates from the permissible value, the upper pair of contacts of the sensor 12 is closed into minus, and the control unit 13 receives a signal. On command from the control unit 13, the crimping force is removed, the arm 8 of the manipulator 9 and the pressing rod 2 with the working plate 3 are raised and moved to a magazine of 14 sheets. The work plate 3 captures the sheet and, returning to its original position, lowers it onto the assembly tool 5, re-checking the height of the stack 4. Then the cycle repeats until the upper pair of contacts breaks open. If the height of the stack 4 of the magnetic circuit deviates from the permissible value of plus, the lower pair of contacts of the sensor 12 closes, and the control unit 13 receives a signal. Upon a command from the control unit 13, the pressing force is removed, the working plate 3 takes the top sheet and transfers it to the store 14. Returning to the initial position, the working plate 3 is lowered and the height of the stack 4 of the magnetic circuit is repeated. Further, the cycle is repeated until the lower pair of contacts of sensor 12 have been turned off. If during the crimping of the package 4 of the magnetic circuit, both pairs of contacts of the sensor 12 remain open, which corresponds to the nominal size of the package of the magnetic circuit (taking into account the tolerance floor of the package), the drive 1, the arm 8 of the manipulator 9 and the pressing rod 2 with the working plate 3 move up to the initial position .

The invention makes it possible to increase the dosing accuracy and the productivity of the device for dosing sheets of magnetic conductors, as well as to exclude the deformation of sheets from the action of mechanical cutters when assembling precision packages of thin sheet steel micromachines.
