Description

The invention relates to manufacturing equipment for the manufacture of electrical machines and can be used in electrical engineering.

A device for forming taps to machines for winding the stators of electric machines is known, including its movable hook, clamping device and drive.

However, the known device does not provide a stable discharge wire taps during the next shuffling of the movable knife for hooking the wire. At the same time, the discharged wires occupy a different position and can be captured by the dvigush, imis organs of the winding head of the old winding machine.

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

The goal is achieved by the fact that the device is equipped with a cam that is rigidly connected to the body of the movable hook, and a hook with a spreader on which is attached a roller interacting with the cam.

FIG. 1 shows the device, obsh, iy view; in fig. 2 is a diagram of the formation of wire leads.

The device contains a movable hook 1, on the case of which there is a knife 2, a copier 3 and a guide, 4, 5. The guide 4 is at the same time a fixed knife with a cut, it has an edge 6. The movable hook 1 and the copier 3 are rigidly connected to each other fork 7, and with a common drive - rod 8.

The hook-ejector 9 is fixed on the base 10, which axles 11 are pivotally connected to the guides 15. On the base 10, the roller 12 is reinforced, with which the hook-ejector interacts with the copier

3. The roller 12 is mounted on the axis 13, fixed in the base 10. Pa of the guides 5 are fixed clamps 14, with which the ejector hook 9 is fixed at the moment the roller 12 enters the free zone of the curve

copier 3. A winding head 16 serves to lay the wire into the grooves of the stator package 15.

The device works as follows. The movable hook 1 with the knife 2 is advanced by the rod 8 of the pneumatic cylinder. The wire coming from the winding head 16 of the machine to the stator 15, when turning the stator to wind the following coil groups, runs onto the plane of the extended hook 1. During the return stroke

hook 1 grips the wire, pulls it away by an amount corresponding to the length of the taps. The return movement of the hook 1 is limited by the stop. When the winding head 16 moves upward, a loop-shaped wire is formed.

b, which is held by the spout of the hook 1.

The hook-ejector 9 is in the initial position and the ke prevents the formation of wire taps.

Pulling out for the next gripping of the wire, the hook 1 moves along with the cam 3, which, acting through the roller 12 on the base 10, leads the ejector hook 9 to the moving hook 1, the spout of which is covered by the wire. With such a position of the hook-dumper 9, the possibility of moving the wire behind the hook is excluded. The movable hook 1 passes under the hook-ejector 9, which drops the wire and leaves it outside the zone of movement of the moving members of the winding head of the machine. Holding the upper retainer 14, the hook-ejector 9 is in the "reset" position until the wire is removed from the nose of the movable hook 1. When the hook 1 moves to grip the wire, the hook-ejector 9 with copier 3 is held off by the pizhpvm lock 14 and retracted into initial position. The movable hook 1 is extended visr and prepared to grip the wire to form the next branch.

Then, when the wire is pulled by the hook I, the hook-ejector 9, being in the initial position, passes the wire and under the influence of the copier 3 moves to the position

“Reset after the wire being pulled off by the hook i passes through the section controlled by the hook-tripper.

The initial position of the hook-ejector 9 is provided at the beginning of the wire stretching by the closed section of copier 3, and on the open section by the lower locking 14. With the wire cut, the stop limiting the return movement of the hook-1 is removed. Knife 2

Imitating hook 1, reaching the cutting edge of the stationary knife, cuts off the end of the wire coming from the stator, and the wire 17 from the winding head 16 is clamped between the pneumatic cylinder body and the hook 1 body.

In the following, the cycle is repeated.

Subject invention

A device for forming taps to the machine for winding the stators of electric masks, comprising a movable hook, on the body of which a knife, a fixed knife, a device for clamping wires and an actuator are installed, characterized in that, in order to increase reliability, the device is equipped with a copier the body of the rolling hook and hook - the ejector, which is fixed to the roller, interacting with the copier.
