Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to an apparatus for automatically assembling a blade member to a member to be assembled in order to obtain a blade wheel part for an automobile (for example, a torque converter internal part), etc. .

BACKGROUND OF THE INVENTION In general, blade wheel components used inside an automobile torque converter are obtained by assembling a blade member to a member to be assembled.

Conventionally, the work of assembling a blade member to a member to be assembled requires steps such as aligning and assembling the surfaces of those members, and requires complicated movements of those members. For this reason, mechanization has conventionally been considered difficult, and assembly has been carried out exclusively by hand by workers.

For example, by grasping the blade member by hand and controlling the posture of the blade member with the fingertips and wrist of the hand, a part of the blade member is fitted into the member to be assembled, and the desired position of the member to be assembled is achieved. Place the blade member on. In this state, the blade member is assembled to the member to be assembled by hitting the upper end of the blade member with a hammer or the like held in the other hand.

Problems to be Solved by the Invention However, in the conventional manual assembly work of blade members, there was a problem that the efficiency was extremely low and productivity did not improve.

Further, in order to improve performance as a blade wheel component, the blade member needs to be assembled to the member to be assembled with high precision. For this reason, the assembly work is highly difficult and the number of workers is limited to skilled workers. Moreover, even when the assembly work is performed by a skilled person, there are large variations in the quality of the assembly.For example, there is a problem in that after assembly, there are variations in the unloading load of each blade member and the pitch between each blade member. .

The present invention was made against the background of the above-mentioned circumstances, and it is an object of the present invention to provide a blade member assembly device that has good assembly accuracy and is capable of continuous automatic assembly.

Means for Solving the Problems In order to solve the above object, the present invention includes a plurality of protrusions formed on a blade member on a circumference of a predetermined radius of a member to be assembled, forming a plurality of protrusions into a set. In a blade member assembly device that attaches a blade member to a member to be assembled by press-fitting the blade member into each set of formed engagement grooves, an indexing device that rotates the member to be assembled and indexes the engagement groove to a predetermined position. a mechanism, and an assembly jig whose tip part moves back and forth with respect to the indexed predetermined engagement groove and holds the blade member in a predetermined attitude by an elastic member. and a hammer member that presses the protrusion into the engagement groove by hitting the blade member whose protrusion is temporarily inserted into the engagement groove using the assembly jig. It is something.

Effect The blade member targeted in the device of the present invention has a plurality of engagement protrusions. Further, the member to be assembled has a plurality of sets of engagement grooves formed on a predetermined circumference. In this assembled member, each set of engagement grooves is sequentially indexed to a predetermined position by an indexing mechanism. On the other hand, the blade member is indexed and held at the tip of a jig that moves back and forth relative to the assembled member, but the tip is held in a predetermined posture by an elastic member. When the jig moves forward with respect to the part to be assembled, the protrusions of the blade members are temporarily inserted into the corresponding engagement grooves without completely engaging, and at that time, the tip of the jig becomes elastic. The posture changes against the elastic force of the members, resulting in a state of so-called temporary assembly. Thereafter, the hammer member operates to strike the blade member, so that each protrusion is press-fitted into the engagement groove, and the main assembly is performed, completing the assembly of one blade member.

Embodiments Next, embodiments of the present invention will be described with reference to the drawings.

In the figure, 1 is a blade member assembly device,
A chute 3 in which a plurality of iron blade members 2 are arranged in an upright manner is arranged. This shot 3
A guide member 4 is disposed below the terminal end of the chute, and a vertical surface of the guide member 4 on the terminal end side of the chute is aligned with the distal end surface of the chute 3 to form a guide surface 4a.

Furthermore, an assembly jig 5 that holds the blade member 2 is arranged along the end of this chute 3, and this assembly jig 5 is moved up and down by a camshaft 7 connected to a drive source 6. Possibly supported.

The distal end of the assembly jig 5 is connected by a coil spring 8 and divided into a separation jig 9, and this separation jig 9 is supported by a fulcrum 10a via a pairing 10.

A recess 9 having a depth corresponding to the thickness of the blade member 2 is provided in the lower part of the separation jig 9 on the side facing the blade member 2.
a is formed, and the iron blade member 2 is attracted and held in this recess 9a by magnetic force.

The blade member 2 held in the recess 9a is sandwiched between the guide surface 4a of the guide member 4 and the recess 9a by the lowering of the assembly jig 5, and is prevented from falling off. A plurality of protrusions 2a are formed on the blade member 2 that is moved downward in this way, and on the other hand, the indexing mechanism 1
A plurality of grooves 12a into which the protrusions 2a fit are formed in the assembled member 12 positioned at 1.

Further, the indexing mechanism 11 is driven by a camshaft 7 connected to the same drive source 6 through which the assembly jig 5 is driven.

Further, a hammer 13 is disposed above the member to be assembled 12 positioned by the indexing mechanism 11 and in parallel with the assembly jig 5.
is configured to strike the blade member 2, which has been moved by the assembly jig 5 and temporarily assembled to the member to be assembled 12, toward the member to be assembled 12 by being operated by the camshaft 7 described above. ing.

The operation of the above device will be explained below.
A large number of blade members 2 are arranged on the chute 3, and at the tip of the chute 3, the leading one blade member 2 is magnetically attracted to the recess 9a of the separation jig 9 connected to the assembly jig 5. (Fig. 1~
Figure 3).

After this suction state is confirmed by a confirmation means (not shown), the assembly jig 5 is moved downward by a camshaft 7 connected to a drive source 6. As the assembly jig 5 moves, the separation jig 9a connected thereto also moves, and the blade member 2 housed in the recess 9a also moves downward (FIG. 4A).

During this movement, the groove 12a of the member to be assembled 12 is indexed in advance by the indexing mechanism 11 operated by the camshaft 7, so that the protrusion 2a of the blade member 2 is fitted into this groove 12a. The position of the member to be assembled 12 is determined in advance.

The blade member 2 is moved toward the member to be assembled 12 positioned in this way, and finally the plurality of protrusions 2a of the blade member 2 fit into the grooves 12 of the member to be assembled 12.
Both members are assembled in such a way that they fit into the respective parts a. During this assembly, the protrusion 2a of the blade member 2 is not firmly fitted into the groove 12a of the member to be assembled 12 as expected, but is in a temporarily assembled state (first Figure 4B).

With the blade member 2 temporarily assembled in this manner and held by the separating jig 9, the hammer 13 is operated by the camshaft 7 connected to the drive source 6, and the blade member 2 is swung downward. That is, the blade member 2 which is temporarily assembled to the member to be assembled 12 is struck by the hammer 13 toward the member to be assembled 12, and the protrusion 2a of the blade member 2 and the groove 12a of the member to be assembled 12 are The main assembly is performed when the two are firmly fitted (fourth step).
Figure C).

Note that during this final assembly, the lower surface of the blade member 2 moves slightly so as to follow the upper surface of the member to be assembled 12. This movement is adjusted by the vertical movement of the coil spring 8 and the rotation of the bearing 10, and functions in the same way when the blade members are assembled to different blade wheel parts.

The to-be-assembled member 12 to which the blade member 2 has been assembled in this manner is further indexed and positioned by another groove 12a on the circumference, and the blade member 2 is successively assembled in the same manner as described above. As a result, a plurality of blade members 2 are attached to the member to be assembled 12 with high efficiency, and a blade wheel component is obtained.

In addition, this assembly device uses one drive source to operate the assembly jig, indexing mechanism, and hammer by the same camshaft, so each action is performed continuously depending on the shape of the cam, and automatic operation is performed. It is possible to complete the assembly work in a timely manner.

However, the device of the present invention is not limited to this, and may be controlled using different drive sources.

Further, in this embodiment, the blade member is attracted and held by magnetic force, but if the blade member is made of a material other than iron and is made of a non-magnetic material such as aluminum, it may be configured to be held by an assembly jig having a different structure. good.

Effects of the Invention As explained above, in the device of the present invention, the blade member, which is elastically rotatably held at the tip, is moved forward with respect to the engagement groove indexed by the indexing mechanism, and temporarily When they are fitted, the tip of the jig elastically changes its posture to maintain the temporarily assembled state, and then the hammer member hits the blade member and press-fits the protrusion into the engagement groove. Therefore, the blade members can be automatically assembled efficiently while maintaining assembly accuracy. Further, since the indexing of the member to be assembled and the holding of the blade member can be performed with constant precision at all times, variations in the assembly accuracy of the blade member can be prevented.
