DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary automatic assembly base machine in which a plurality of transfer units are arranged.

[0002]

2. Description of the Related Art Conventionally, in a rotary automatic assembly base machine (automatic assembly machine), a shaft is passed through the center of a turntable, and a transfer unit is mounted above the turntable. Also,
In order to stabilize the transfer unit, some columns were provided with reinforcements outside the turntable and reinforced.

[0003]

This has the following disadvantages. (A) Since a plurality of transfer units are mounted on one shaft, the strength is insufficient and it is difficult to stabilize the unit. (B) Since the transfer unit is installed in the center,
I could not see the whole working condition on the turntable. The present invention has been made to solve these disadvantages.

[0004]

The rotary automatic assembly base machine according to the present invention comprises: (a) a drive motor 13;
(B) the up-down movement cam 20 and the back-and-forth movement cam 21 which are respectively driven to rotate by the drive motor 13; and (c) the up-down movement cam 20 through the first arm 18 which comes into contact with the up-down movement cam 20, respectively. (D) a first vertically moving shaft 5 and a hollow second vertically moving shaft 6 to be driven;
Plate 4 attached to both vertically moving shafts 5, 6
(E) a front-rear movement shaft 11 that is disposed through a hollow portion of the second vertical movement shaft 6 and is driven by the front-rear movement cam 21 via a second arm 19 that contacts the front-rear movement cam 21; f) While being attached to the plate 4, the longitudinally moving shaft 11 is connected via the connecting members 9, 10 and 12.
And a plurality of transfer units which are simultaneously operated up and down by the plate 4 and simultaneously rotated by the front and rear movement shaft 11 are provided. More specifically, the transfer unit is attached to the plate 4, and first and second vertically moving shafts 5 and 6 are provided at both ends of the plate 4, and the lower ends thereof are attached to the holder 16. The first arm 18 that contacts the vertical cam 20 is connected to the center of the holder 16. Then, the transfer unit is sequentially connected to the longitudinal shaft 11 via the rod 7, the lever 8, the lever 9, the rod 10, and the lever 12. Forward and backward movement shaft 1
1 passes through a hollow second vertically moving shaft 6, and has its lower end connected to a second arm 19 which comes into contact with a longitudinally moving cam 21 via a rod 22. This is a rotary automatic assembly base machine having the above configuration.

[0005]

When the drive motor 13 rotates, the chain 27
This causes the camshaft 17 to rotate. Camshaft 1
7 rotates, and the first arm 18 rotates.
The holder 16 moves up and down via. The vertically moving shafts 5 and 6 provided at both ends of the holder 16 and the plate 4 move up and down, and as a result, the attached transfer unit moves up and down. The longitudinal cam 2 provided on the camshaft 17
When 1 rotates, the front-rear movement shaft 11 rotates by the second arm 19 and the rod 22. Upper lever 12
The rotation movement is transmitted to the lever 8 by the rod 10 and the transfer unit is rotated by the rod 7.
The components on the turntable can be assembled by rotating and vertically moving the transfer unit as described above.

[0006]

Embodiments of the present invention will be described below. (A) The chuck unit 1 is attached to the front end of the front and rear guide 2 which slides the front and rear unit 3. The transfer unit is configured as described above. (B) The transfer unit is attached to the plate 4, and first and second vertically movable shafts 5 and 6 are provided at both ends of the plate 4, and both vertically movable shafts 5 and 6 are respectively held by bosses 14. The second vertically moving shaft 6 is hollow. Attach the lower ends of both vertically moving shafts 5, 6 to the holder 16,
A first arm 18 is connected to the center of the holder 16, and the first arm 18 is brought into contact with a vertically moving cam 20 provided on a camshaft 17. (C) The transfer unit and the lever 8 are connected by the rod 7. Then, the lever 8 is connected to the upper end of the longitudinal movement shaft 11 passing through the vertical movement shaft 6 via the lever 9, the rod 10, and the lever 12, and is connected to the lower end of the longitudinal movement shaft 11 via the rod 22. Then, the second arm 19 is connected. The second arm 19 is brought into contact with the forward and backward moving cam 21. (D) a sprocket 26 provided on the camshaft 17;
The motor 13 is connected by a chain 27. (E) The drive sprocket 23 of the turntable 15
Are connected by a chain 24 to a sprocket 25 provided on the camshaft 17. The present invention has the above structure.

[0007]

According to the present invention, the plate on which the transfer unit is mounted is supported by the two shafts, so that the strength is increased and stable and accurate assembly can be performed. Since there are no obstacles on the turntable, the overall work status can be seen at a glance.
