Description

one

The invention relates to the bottom-end industry and can be used in the assembly of rolling bearings.

A device for placing piece blanks, for example, semi-separators, in a machine for assembling ball bearings containing 1e coaxially mounted on the base of a core magazine, cutters, retainers and their movement mechanism U is known. A disadvantage of the devices is that it does not provide for the continuous installation of blanks with a single core magazine .

The purpose of the invention is to ensure the continuous installation of blanks with one core magazine.

The goal is achieved due to the fact that the device contains a core magazine coaxially mounted on the base, cut-off devices, retainers and the mechanism of their movement. The device is equipped with two rows of clamping levers mounted on the base with alternate interaction with the magazine, the upper row of which is rigidly connected to the retainers, and the bottom - to the cutters, while the retainers are made with orienting semi-separators.

On Fig.1,2 shows the device, the section; in fig. 3 shows a section BB in FIG. one; in fig. 4 shows a section on B-b in FIG. one.

On the base 1, the clamping levers 2 and 3 of the upper row, the clamping levers 4 and 5 of the lower one are pivotally mounted.

0 row and the cam 6, interacting with the rollers 7 and fixed at the ends of the clamping levers, which are pressed by the springs 8 to the stops 9. Between the clamping levers are placed rod 5 neva store 10 with half separators 11. On the clamping levers of the upper row there are spherical lodgements 12, on the lower arms of the clamping levers, there are cut-offs 13 and lodgements 14. On the upper and lower levers there are locking lugs 15 interacting with the openings. rod shop.

The device works as follows.

In the initial position, the cam 6 is in the neutral position and does not interact with the clamping levers. 1.2). Both p and the clamping levers are compressed by the springs 16 and

in contact with the core magazine. Under the action of the springs 8, they are attracted to the stops 9, which determine their position and, consequently, the position of the core magazine 10. The semi-separators rest on the slam-shut 13, one semi-separator, previously dropped, lies on the cradles 14 of the lower row of levers. The cam 6 rotates counterclockwise and expands the lower row of levers, while the cutters 13 associated with the levers are consumed. The semi-separator located on the lodgements 14 of the lower row of levers is dropped onto the bearing, and the column of semi-separators is lowered onto the lodgements 12 of the upper p of the levers. Cam 6 starts to move clockwise and returns to the neutral position. The lower row of levers is clamped, clamping the rod, the cutters 13 connected to the lower row penetrates into the gap between the two lower half separators. The cam b then continues to rotate clockwise and expands the upper row of clamping levers. The severed semi-separator falls on the lodgements of the 14 lower p and the levers. In this position, the core magazine 10 is held by the lower row of clamping

leverage. The cam returns to the neutral position. The upper row of arms is reduced by squeezing the rod.

In the sequel, the cycle of loading the half separators is repeated.
