Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a transfer pallet suitable for an automatic tripod assembly machine.

[Prior Art] An automatic tripod assembly machine automatically rotates rolling elements such as inner and outer retainers, rollers, needles, and snap rings on three protruding shafts that extend radially by rotating the tripod by 120 degrees. There is a carrier pallet for holding and moving the tripod in this case (for example, Japanese Utility Model Publication No. Sho 64-6179).

[Problems to be Solved by the Invention] This type of transfer pallet is a combination of a base and a mounting member, and therefore has a complicated shape and becomes heavy, and is surrounded by a circular peripheral wall except for a portion facing the assembling machine. Because
It is not possible to confirm whether the stopper is locked with respect to the protruding shaft of the work and whether the position of the work has been accurately indexed, or whether the work is completely locked.

SUMMARY OF THE INVENTION The present invention has a technical problem to provide a carrier pallet for an assembling machine, which has a simple shape and is light in weight, and the peripheral wall can be removed to easily confirm the work indexing position and the locking state of the protruding shaft. Is.

[Means for Solving the Problem] As a means for solving this technical problem, the present invention provides a flat plate-shaped base, a workpiece fitting shaft erected at the center of the base, and the shaft. The work supporting member is provided on the base with a predetermined angle on the circumference of the center, and the work supporting member is erected on the base so as to face the shaft, and the work supporting member is an attachment member fixed to the base. The lower end portion is pivotally supported and has a center lever that is urged by a rotational force in the shaft direction via a spring, and the center of the protruding shaft of the work fitted into the shaft is located inside the upper portion of the center lever. The gist is that the centering pins fitted into the holes are attached.

[Operation] Since the work fitting shaft and the two work supporting members are erected on the flat base, the work piece has a simple shape and is light. Since there is no peripheral wall, the work indexing position and the protruding shaft are locked. The condition can be easily confirmed.

[Embodiment] An embodiment of the present invention will be specifically described below with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 denotes a flat plate-shaped base, and notched grooves 1a which engage with guides 2 for transportation are formed on both side surfaces thereof as shown in FIG. 2, and can be moved along the guides. It is like this. A shaft 3 for fitting a work is erected at the center of the base 1, and two work support members 4 are provided on a circumference centered on the shaft 3 with a center angle of 120 degrees. It stands on the base 1. The work supporting member 4 has a center lever 41 facing the shaft 3 as shown in FIG. 3, and the lower end portion thereof is a bracket-shaped mounting member fixed on the base 1.
A horizontal piece 41a, which is pivotally supported by a pin 43 on the 42 side and projects outwardly, is integrally held by the base 1 via an adjusting screw 44, and further between the horizontal piece 41a and the base 1. The spring 45 is contracted around the adjusting screw 44 so that the center lever 41 applies a rotational force to the shaft 3 side (clockwise in FIG. 3) with the pin 43 as a fulcrum. Further, a centering pin 46 is attached to the inner surface of the upper portion of the center lever 41 via a spacer 47 with the amount of protrusion adjusted. Reference numeral 5 is an escape pin attached to the corner of the base 1.

The transport pallet according to the present invention is configured as described above,
Fit the shaft hole of the tripod work 6 into the shaft 3,
The work 6 is supported by fitting and locking the centering pins 46 of the work supporting member 4 into the center holes 61a of the two projecting shafts 61, respectively. The transport pallet supporting the work 6 is moved to an assembling machine for each component along the guide 2 with which the notch groove 1a of the base 1 is engaged, and the components are sequentially assembled to complete the tripod. In each assembling machine, while rotating the work 6 supported by the transport pallet by 120 degrees, the three projecting shafts 61 are sequentially indexed to the assembling position P and the necessary parts are automatically assembled. At this time, the centering pin 46 of the work supporting member 4 causes the center holes 61a of the two projecting shafts 61 of the work 6 to be aligned.
It is possible to easily visually confirm from the outside whether or not they are properly fitted into each of the two, so that one protruding shaft can be attached to the mounting position P.
It is possible to check whether or not it has been correctly indexed. Further, after the parts are assembled, the work supporting member 4 supports them again, so that the assembled parts can be prevented from coming off. After that, the transport pallet is sent to the next assembling machine to assemble the next parts. Although the last one of the three axes of the tripod is not pressed by the center lever, this axis is orthogonal to the transport direction, so the pallet is sent to the next assembly machine. At that time, the assembled parts do not fall.

The above-described assembling work is performed while continuously feeding the transport pallets, but when the transport pallets become narrow and the front and rear transport pallets come into contact with each other during transport, they can be easily separated by using the escape pin 5. .

[Effects of the Invention] As described above, according to the transfer pallet of the present invention, the overall shape is simple and the weight is reduced, and the engagement state of the support member with the projecting shaft of the work can be observed from the outside, and the correct indexing is performed. The position can be easily confirmed, and the assembled parts can be prevented from falling, which is an excellent effect. Further, there is an advantage that a wide space near the assembling position can be secured and the assembling work by each assembling machine can be surely and smoothly performed.
