Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component mounting device for mounting components on a heavy steering column.

[0002]

2. Description of the Related Art In a vehicle assembly line, an intermediate shaft is joined to a lower end of the steering column by a joint before a vehicle is assembled to the vehicle, and a steering column is attached to an upper end of the steering column as shown in FIG.
A dimmer switch and a turn signal switch operated by levers 13 and 14 are assembled as shown by.
In assembling these parts, the steering column was placed on the processing table with the horizontal axis direction.

[0003]

The lower end and the upper end of the steering column mounted on the processing table in the horizontal axis direction are located on the left and right sides of the processing table when viewed from the front of the processing table. For example, if the lower end of the steering column is located on the right and the upper end of the steering column is located on the left, the operator moves to the right to join the intermediate shaft with the joint, and then moves to the left to switch the dimmer switch. And a turn signal switch, etc., and the worker is working in a bent posture because the height of the assembling position is low in the work of assembling the dimmer switch and the turn signal switch. Therefore, since the worker must always move to the left and right with respect to the steering column, the time required for the movement becomes a loss time, which affects the assembling work efficiency and has a problem that the labor burden of the worker is large. there were.

An object of the present invention is to solve the above-mentioned conventional problems,
An object of the present invention is to provide a component mounting apparatus that enables a worker to perform a work of assembling parts to a steering column at a fixed position, thereby improving work efficiency and reducing a burden on the worker.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a horizontal turntable supported on a base so as to be rotatable around a vertical axis, and a turntable on the turntable. A movable table that is attached via a hinge so as to rotate upward and tilt at a required angle in a parallel position, and that supports a steering column; a turntable rotation actuator that rotationally drives the turntable; and the movable table. A movable platform actuating actuator that operates in a horizontal position and an inclined position, and a foot switch for controlling the turntable rotating actuator and the movable platform operating actuator is disposed close to a front position of the base. It is characterized by the following.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a base fixed on a floor, and FIG. A rotary shaft 2 is mounted on the base 1 so as to be rotatable about a vertical axis, and a horizontal turntable 3 is fixed on the rotary shaft 2. This turntable 3 is driven by a turntable rotation actuator as shown in FIG.
Is rotated at a rotation angle of 90 degrees from the state shown in FIG. As the turntable rotation actuator, a turntable rotation cylinder 4 fixed to the base 1
Are connected to the turntable 3.
Note that, instead of the turntable rotating cylinder 4, a motor with a speed reducer may be connected to the rotating shaft 2.

A movable base 5 is mounted on the turntable 3 via a hinge 6 so as to be rotated at a position parallel to the surface of the turntable 3 and upward and inclined at a required angle. On the movable table 5, supporting members 7, 8 for supporting the steering column W in the horizontal axis direction while the movable table 5 is horizontal are fixed. A movable table operating cylinder 9 is fixed on the movable table 5 as a movable table operating actuator that rotates the movable table 5 in a position parallel to the surface of the turntable 3 and upwards and tilts at a required angle. In this configuration, the piston rod of the movable table operating cylinder 9 is connected to the turntable 3. A motor with a speed reducer may be provided at the hinge 6 instead of the movable table operating cylinder 9.

Further, a pedal-type foot switch 15 for controlling the turntable rotating cylinder 4 and the movable base operating cylinder 9 is arranged close to the front position of the fixed base 1.

Since the present invention has the structure as described above, when the steering column W is mounted, the movable base 5 descends on the turntable 3 as shown by the solid line in FIG. When the steering column W is mounted on the support members 7 and 8 on the movable base 5, the turntable 3 is positioned, for example, such that the lower end side A of the steering column W is on the right side when viewed from the front of the base 1. The state where the upper end side B of the steering column W is located on the left side is defined as an original position. The positions of the lower end side A and the upper end side B of the steering column W may be reversed.

In the above state, the steering column W is placed on the support members 7 and 8 and an operator standing at a fixed position on the front of the base 1 firstly positions the steering column W on the right side when viewed from the front of the base 1. Is performed to join the intermediate shaft W1 to the lower end side A by the joint 10.

After the assembly work of the intermediate shaft W1 is completed, a dimmer switch, a turn signal switch and the like 11 are assembled on the upper end side B of the steering column W located on the left side when viewed from the front of the base 1. The dimmer switch and the turn signal switch 11 are connected to the steering column W
When the steering column W is in a horizontal axis direction as shown by the solid line in FIG. 1, the worker must turn around to the left side of the base 1,
The operator bends his / her waist to correspond to the location where the dimmer switch, turn signal switch, and the like 11 are assembled.

Therefore, in the present invention, after the assembly work of the intermediate shaft W1 is completed, the foot switch 15 is operated to move the turntable 3 to the upper end side B of the steering column W by the turntable rotating cylinder 4 so that the front side B of the base 1 is on the front side. , And at the same time, the movable table 5 is rotated upward by the movable table operating cylinder 9 with the hinge 6 as a fulcrum, and the movable table 5 is tilted as shown by the dotted line in FIG. 1 and FIG. The angle of inclination of the movable base 5 depends on the height of the worker, but is preferably about 45 degrees.

The end surface of the upper end side B of the steering column W is turned to the front side of the base 1 by rotating the turntable 3 by 90 degrees, and furthermore, the inclination of the movable base 5 allows the operator to operate a dimmer switch, a turn signal switch 11 or the like. This is a position where you can work without bending your waist when assembling.

Thus, when assembling the dimmer switch, the turn signal switch and the like 11 on the end surface of the upper end side B of the steering column W, the worker does not turn to the left side of the base 1 or fix the front of the base 1 without bending the waist. The assembly work can be easily performed at the position.

A dimmer switch, a turn signal switch, and the like 11 are provided on an end surface of the upper end side B of the steering column W.
After the completion of the assembling work, the foot switch 15 is operated to lower the movable base 5, and the turntable 3 is reversely rotated by 90 degrees to return to the original position, and the steering column W having the assembled parts is supported by the support members 7, 8. And then replaced with a steering column W to be assembled.

[0016]

As described above, according to the present invention, when assembling parts at the lower end and the upper end of the steering column, the operator does not move to the lower and upper ends of the steering column without moving to the front of the base. It can be done in a fixed position, and the upper end of the steering column, which was assembled with the worker's waist bent, is tilted and raised to a height that is easy to assemble, improving work efficiency In addition, there is an advantage that the labor burden of the worker is reduced.
