Abstract

PURPOSE:To dispense with a special driving source and simplify the composition by making an assembling jig on a turntable reversible through utilizing a turning a turning effort of the turntable in a reversal device specially used for pushing an end stone by pressure into a bearing of a level meter. CONSTITUTION:When an assembling jig 14 supporting a level meter bearing comes to a bearing reversal station due to rotation of a turntable 2, an impeller 13 of said jig 14 is released from rotation control by a disc 8 correspondingly to a notch part 15 of the disc 8 provided on the turntable 2, then the impeller 13 strikes on reversal pin 19 installed on the disc 8 to be rotated by about 90 deg. With further rotation of the turntable 2, the impeller 13, after separation from the reversal pin 19, makes contact with an edge face of the notch part 15 of the disc 8 and is rotated by 90 deg. to put a shaft 12, with a retaining click 11 of the assembling jig 14, in rotation by 180 deg.. This results in the same effect as that of reversal of the bearing. After this reversal, two points of the impeller 13 make contact with the under surface of the disc 8 and the impeller is conveyed maintaining a definite angle with the disc.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reversing device that is effective for inserting level meter stones on both sides.

Generally, the process of assembling the level meter stone was carried out by an automatic machine as shown in Figure 1.

In other words, the turntable 2 provided on the base 1 is
The bearing 3 shown in FIG. 2 is inserted into the assembly jig of the turntable 2 at the A station, the B station is an idle station, and the C station =/ Insert the jewel 4 into the upper part of the bearing 3 at the station D, press-fit the jewel 4 at the station D, check the press-fit condition of the jewel 4 at the station E, reverse the bearing 3 at the station F, and press the jewel 4 at the station D. Play stay 7:
Insert the jewel 4 into the bearing 3 at the H station,
■Press-fit this gemstone 4 at the station, inspect the press-fit condition at the J-station, and take out the non-defective pieces at the K-stay/funnel.
The assembly of the jewel 4 into the bearing 3 was planned during the process of inverting the assembly jig using the L-stain yon.

The reversing mechanism of the assembly jig in the above manufacturing process is as follows:
An assembly jig that transmits power from a power source to the reversing position is used, which has the disadvantage of requiring a separate power source, making the configuration complicated and disadvantageous in terms of cost.

The present invention aims to eliminate the above-mentioned conventional drawbacks, and provides a reversing device that does not require a special power source and is capable of reversing an assembly jig with a simple configuration.

Embodiments of the present invention will be described below with reference to FIGS. 3 to 9 of the drawings.

A main shaft 6 is installed upright on the base 1, and a turntable 2 having 12 stations is pivotally connected to the main shaft 6 as described above.A gear 6 connected to the lower end of the turntable 2 has a saver The indexed transmission gear 7 is in mesh.

A disk 8 is fixed to the upper end of the main shaft 6.

A shaft 12 having a holding claw 11 for holding the bearing 3 of the above-mentioned level meter at the tip thereof is located at the position divided into 12 equal parts on the upper surface of the turntable 2. is rotatably incorporated into the rear end of this shaft 12.
An assembly jig 14 is added to connect the impeller 13 having the protruding parts.

Further, a notch 16 is provided in the disc 8 at a position slightly in front of the reversing stations F and L of the evening table 2, and a compression spring is inserted into the notch 16 into the holding cylinder 17 via the bracket 16. A reversing pin 19 is provided which is incorporated with 18. The lower end of this reversing pin 19 protrudes downward from the notch 16 of the disc 8, and the impeller 13 of the assembly jig 14
It is designed to respond and engage. Further, the disc 8 is normally in contact with the impeller 13 to prevent the impeller 130 from rotating.

With this configuration, when the assembly jig 14 holding the bearing 3 of the level meter rotates to the F station, the impeller 13 rotates in a circle corresponding to the notch 16 of the disc, as shown in FIG. The rotation restriction by the plate 8 is released, and as shown in FIG. 7, the impeller 13 hits the reversing pin 19 and is rotated about 90 degrees as shown in FIG. 8, and further rotates the turntable 20 times as shown in FIG. 9. Although it is separated from the reversing pin 19, the impeller 1
3 comes into contact with the end face of the notch 16 of the disk 8 and rotates 90 degrees, and the shaft 12 having the holding claw 11 of the assembly jig 14 is rotated 180 degrees, thereby inverting the bearing 3.

After this reversal, the impeller 1302 points contact the lower surface of the disk 8, and the disk is conveyed while maintaining a constant angle.

The reason why the compression spring 18 is combined with the reversing pin 19 is that when the impeller 13 is rotated by the reversing pin 19, -
Reverse pin 1 so that reversal pin 19 can escape in the opposite direction.
The purpose is to prevent damage due to large loads being applied to the parts 9.

The reversing device of the present invention is constructed as shown in Figure 1, but since it utilizes the rotational force of the turntable, it does not require a special drive source, and is simple and inexpensive to construct, and its operation is stable. It is highly reliable and has great industrial value.

In the explanation given above, an example is shown in which a stone is press-fitted into a level meter bearing, but it can be applied to any assembly process that requires reversal.
