Description

[Detailed description of the invention] The present invention relates to an inner core assembly device for a torque converter, and more specifically, to an assembly device used when assembling the blades and the inner core of a torque converter turbine using a plug-in method. .

The shell, blades, and inner core that make up the torque converter turbine are assembled by inserting the assembly protrusions protruding from both end faces of the blades into the assembly holes formed in the shell and inner core, and after inserting the assembly protrusions. Caulk (bend) the tip
By doing so, they become integrated with each other.

Conventionally, to obtain such an integrated product, the following steps were followed.

A first assembly protrusion protruding from one end surface of each of the plurality of blades is manually inserted into the assembly hole of the shell to temporarily assemble the blades.

Place the inner core on the temporarily assembled blade, manually correct the attitude of the blade with respect to the shell with a hammer, etc., and attach the second assembly protrusion protruding from the other end surface of the blade. Insert into the assembly hole formed on the inner core (this insertion is incomplete because the fit between the second assembly protrusion and the assembly hole on the inner core is said to be relatively tight) , this insertion work is performed for each blade.

By applying a force that strongly clamps the blade between the shell and the inner core,
The second assembly protrusion is completely inserted into the assembly hole of the inner core to obtain a temporary assembly of the three members.

The tips of the first and second assembly projections are caulked (bent) to obtain a complete assembly of the shell, blade, and inner core.

In the conventional assembly work as described above, the blades have a complicated shape with a three-dimensional curved surface, each blade has a plurality of second assembly holes, and the number of blades is large. Because there were so many sheets (around 30 sheets), the above-mentioned task was particularly difficult. In other words, the blade posture correction mentioned above is due to the fact that the fit between the first assembly hole and the shell assembly hole is relatively loose, and the blade is formed by press punching, so the dimensional accuracy is not very good. This is done because the assembly posture of each blade with respect to the shell is not necessarily constant, but while correcting the posture of each of the many blades, the second assembly protrusion is adjusted for assembly of the inner core. Inserting it into the hole is extremely time consuming, and in particular, this work cannot be completed in one go, and usually requires two or three re-adjustments before being completed. Furthermore, since the blade is formed by press punching and has burrs, there is also the problem that workers' hands and fingers are likely to be damaged during assembly work.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide an assembly device that can automatically perform the above-mentioned work as well as the above-mentioned work.

In order to achieve such an objective, the present invention has the following configuration. That is, a turntable is mounted and fixed on which a shell is rotatably driven and has a blade pre-assembled on its upper surface having a protrusion for assembling to the inner core; an annular pressurizing plate having an assembling hole into which an assembling protrusion is inserted and abutting the upper surface of the inner core placed on the blade; and an annular pressurizing plate disposed inside the pressurizing plate; The apparatus comprises: an alignment pressing body that sequentially contacts the blades to align the blades when the turntable is rotated; and a pressing means that presses the pressure plate downward. .

The present invention will be described in detail below with reference to drawings showing embodiments thereof.

1 and 2, a turntable 2 is rotatably held on a base 1 via a bearing (not shown), and the turntable 2 is rotationally driven by a motor 3. As shown in FIGS. A shell 5 to which a blade 4 has been assembled in advance is placed on the top surface of the turntable 2.
is positioned on the turntable 2 by, for example, a pin 6 and is rotated integrally therewith.

A support head 7 is disposed above the turntable 2, and the support head 7 is movable up and down by a drive source including a cylinder device (not shown).
A pin-shaped alignment pusher 10 is attached to a bracket 8 integrated with the lower surface of the support head 7 via a spring 9. In the embodiment, a plurality of alignment pressing bodies 10 are provided at intervals in the circumferential direction of the turntable 2, and the tip of such alignment pressing bodies 10 is placed on the turntable 2 during use. It is adapted to come into contact with the blade 4.

A plurality of hanging pins 11 are held in the support head 7 so as to be able to freely swing in the vertical direction, and the upper ends of the hanging pins 11 have large diameter heads 11a.
Falling from the support head 7 is prevented. At the lower end of this hanging pin 11 is an annular intermediate head 12.
is fixed, and a roller 13 is fixed to the intermediate head 12.
An annular pressurizing plate 14 is rotatably held therethrough. The intermediate head 12, that is, the pressure plate 14, is always urged downward by a spring 15 fitted around the outer circumference of the hanging pin 11.

A pressure head 16 is arranged above the hanging pin 11, and the pressure head 16 is raised and lowered by a cylinder device 17 attached to the support head 7, for example. When the pressurizing head 16 is driven downward, it comes into contact with the large diameter head 11a of the hanging pin 11 and presses it downward.

Here, blade 4, shell 5, inner core 1
8 will be explained with reference to FIG. 3 and subsequent figures. First, as shown in FIGS. 3 and 4, the blade 4 has three first assembly projections 4a protruding from one end surface thereof, and two second assembly projections 4a from the other end surface. A protrusion 4b is provided in a protruding manner. In addition, as shown in FIG. 5, the shell 5 has three
The assembly hole 5a is
is the one into which the first assembly protrusion 4a of the blade 4 is to be inserted. Furthermore, as shown in FIG. 6, two assembly holes 18a are formed in the inner core 18 for one blade 4, and the assembly holes 18a are used for the second assembly of the blade 4. The protrusion 4b is to be inserted.

Note that the blade 4, shell 5, and inner core 18 as described above are the same as those of the prior art, so no further detailed explanation will be given. Of course, the numbers of the first and second assembly projections 4a, 4b and the corresponding assembly holes 5a, 18a can be set as appropriate.

Next, the operation of the above-mentioned component device will be explained. First, as shown in FIG. , placed on the upper surface of the turntable 2, and positioned using the pins 6. Next, insert the inner core 18 on the blade 4.
Place. Note that until the above work is completed, the support head 7 is positioned further above the position shown in Fig. 1, and after the above work is completed, the support head 7 is lowered to the position shown in Fig. 1. put.

After this, when the turntable 2 is driven to rotate in one direction by the motor 3, this turntable 2
The blade 4 that rotates integrally with the aligning presser 10
The blade 4 is brought into contact with the blade 4 sequentially, and the attitude of the blade 4 is corrected. That is, each blade 4 is connected to the aligning press 1
0, when the blade 4 is viewed from the radial direction of the shell 5, the blade 4 uniformly assumes a posture slightly tilted in one direction. And this turntable 2
During rotation, the pressurizing plate 14 lightly contacts the upper surface of the inner core 18 under the biasing force of the spring 15, and as the alignment of each blade 4 progresses, the second assembly protrusion 4b of each blade 4 The second assembly protrusion 4b is matched with the corresponding assembly hole 18a of the inner core 18, and the second assembly protrusion 4b is shallowly inserted into the assembly hole 18.

As mentioned above, the second assembly protrusion 4b is connected to the assembly hole 1.
8a (this confirmation can be done, for example, by detecting that the pressurizing plate 14 has been displaced slightly further downward than in FIG. 1), the turntable After stopping the rotation of the pressurizing head 16, the cylinder device 17 lowers the pressurizing head 16. As the pressurizing head 16 descends, the hanging pin 11, that is, the pressurizing plate 14 descends, and the pressurizing plate 14 forcibly pushes down the inner core 18.
By pushing down the inner core 18, the second assembly protrusion 4b is completely inserted into the assembly hole 18a, and a temporary assembly of the shell 5, blade 4, and inner core 18 is obtained (see FIG. 2). Thereafter, the pressurizing head 16 and the support head 7 may be moved upward to remove the temporary assembly from the apparatus.

As is clear from the above description, the present invention allows efficient assembly of the inner core to the blade (blade/shell temporary assembly).
