Description

[Detailed Description of the Invention] The present invention relates to an assembling machine used for assembling, for example, a bulkhead plate for reinforcement into a workpiece. In other words, the present invention relates to an assembly machine used for inserting and fixing the partition wall plate at a predetermined position in a workpiece having a substantially C-shaped cross section.

Conventionally, in a reinforcement rear bumper with a lip portion and a lip groove-shaped cross section, several reinforcing bulkhead plates are inserted into predetermined positions inside the bumper, and then the bulkhead plates are welded and fixed to the bumper. The process of making it into a subassembly is being taken. However, all the work in this process is done by hand, so it is necessary to widen the lip,
When welding and fixing the bulkhead plate housed in the bumper, in order to hold the bulkhead plate in a stable state and securely fix it in place, press the bumper from the outside to narrow the bumper and attach it to the bumper. The work of holding the partition wall plates together is extremely complicated, requires time and skill, and is generally inefficient and problematic.

The present invention has been developed in view of the above-mentioned problems, and its purpose is, for example, to expand the lip of a workpiece with a lip groove-like cross section, such as a bumper, to transport a bulkhead plate, and to transport a partition plate inside a workpiece. insertion into,

A guide roller 34 is attached to the lower end of the bracket 10, which is in contact with the inner bottom surface of the workpiece 22 and is rotatable. 26 is a stopper provided on the frame 1. Note that 40 indicates the starting position of the rotary table 6 that moves together with the carrier 5.

The operation of this embodiment having the configuration as described above will be described below.

When the rotary table 6 is in the starting position indicated by reference numeral 40, the partition plates 23 are attached to the two plate holders 9, respectively. On the other hand, the workpiece 22, which has both ends open, is positioned and placed on the workpiece receiver 25 using the stopper 26. When the rotary table 6 is started, the trunnion cylinder 11 is not operating and the rotary table 6 maintains a horizontal state. In addition, the table cylinder 21 is not operating in the roller holder 17, and the rollers 15,
16 is in a state as shown in FIG.
5 and 16 can be inserted between the lip portions 22' and 22'' of the workpiece 22 without coming into contact with the lip portions 22' and 22''.

In the above state, the operation of the assembly machine is started. First, when the traverse cylinder 4 is actuated, the rod 36 protrudes, and the rotary table 6 moves forward together with the carrier 5 along the guide portion 3 of the slide base 2 on the frame 1 as shown by arrow A.
The conveyance of the partition plate 23 continues in the above-described state until immediately after the front roller holder 17 enters the workpiece 22. Immediately after the roller holder 17 enters the workpiece 22, the plate holder 9
Before the partition wall plate 23 held at the table enters the workpiece 22, the table cylinder 21 is activated and the rod 37 is extended in the direction of arrow B. Then, the rack 20 connected to the rod 37 slides along the guide section in the rack guide 8. At this time, the pinion 19 meshing with the rack 20 rotates, and the roller holder 17 rotates together with the rollers 15 and 16 via the shaft portion 18, resulting in a state as shown in FIG. That is, the rollers 15 and 16 are connected to the lip portions 22' and 22', respectively.

22'' and rotates while moving.
Since the partition wall plate 23 is positioned rearward than the rollers 15 and 16 and is conveyed, its conveyance is carried out by the roller 1.
This is easily and smoothly carried out within the workpiece 22 expanded by 5 and 16.

The bracket 10 is attached further to the front side than the roller holder 17 on the front side, and the guide roller 34 attached to the lower end of the bracket 10 is attached to the workpiece 22.
The partition wall plate 23 rotates in contact with the inner bottom surface of the workpiece 22 to prevent floating objects from floating on the workpiece 22, and in turn, the partition wall plate 23 rotates in contact with the inner bottom surface of the workpiece 22.
It serves to ensure the insertion of the

Conveyance of the partition plate 23 into the workpiece 22 is continued until the guide roller 34 comes into contact with the stopper 26. Of course, when the partition plate 23 has been transported, the partition plate 23 is at a predetermined position within the workpiece 22.

When the transport of the partition plate 23 into the workpiece 22 is completed, the table cylinder 21 is reversely operated, the clamper mechanism is operated, and the partition plate 23 is removed from the plate holder 9 in this order. That is, when the table cylinder 21 reversely operates, the rod 37 moves in the direction opposite to the direction of arrow B, and the rod 37 moves in the direction opposite to the direction of arrow B.
As shown in the figure, rollers 15 and 16 are connected to the lip portion 2.
2', 22''.Then, the cylinder 29 is activated.When the cylinder 29 is activated, the rod 39 moves in the direction of arrow C, and moves through the knuckle 30 and the link 31 to the pedestal 32. The pair of clampers 27 and 28 operate so as to approach each other using the pin 33 engaged with the workpiece 2 as a fulcrum.
Approximately both ends of the partition plate 23 are clamped, and thus the partition plate 23 is firmly held on the workpiece 22. after that,
The carrier 5 is moved slightly backward to separate the partition plate 23 from the locator 24 of the plate holder 9.

Thereafter, when the trunnion type cylinder 11 is operated and the rod 38 moves downward, the rotary table 6 is pivoted to the rod 38 by the pin 12, so the rotary table 6 is moved in the transport direction of the workpiece receiver 25 with the pin 7 as the center. Rotate as shown by arrow D in the direction intersecting with .
During this rotation, the bottom of the rotary table 6 is placed at the stopper 1.

In this state, when the traverse cylinder 4 operates in reverse, the rotary table 6 moves backward together with the carrier 5 and returns to the starting position. Once returned to this position, the trunnion-type cylinder 11 operates in reverse, and the rotary table 6 rotates in the opposite direction to the arrow D. This rotation is stopped when the bottom surface of the rotary table 6 comes into contact with the stopper 13. In this way, the rotary table 6 is in the initial horizontal state,
Preparation is made for transporting the next partition wall plate 23.

Note that prevention of floating of the workpiece 22 may be done by means such as vacuum suction from the lower surface of the workpiece 22 or seating the workpiece 22 on the workpiece receiver 25 by electromagnetic action, instead of relying on the guide rollers 34. . Further, the holding mechanism for the partition plate 23 on the plate holder 9 may be a mechanism using a permanent magnet instead of the locator 24.

In this assembly machine, during the above operation, the partition plate 23
The bulkhead plate 23 is fixed to the workpiece 22 by joining, welding, or similar means at the time when the workpiece 22 is clamped by the clampers 27 and 28 or when the carrier 5 returns to the starting position. I can do it.

With the present invention as described above, it is possible to automatically expand the lip portion of a workpiece having a lip groove-like cross section, transport and insert the partition plate into the workpiece, and clamp the partition plate through the workpiece. , we can provide an assembly machine that can dramatically improve work efficiency.
