As shown in FIG. 8, the guide bushings 632 and 636 form a semi-circular split hollow type when formed into a circular ring cross section and when separated, form a semi-circular ring cross section.

Each of the guide bushings 632, 636 has a central radius 632c, 636c that is relatively small in size relative to the top inner radii 632a, 636a, and has a top inner radius 632a, 636a and a center radius 632c, 636c. ), The inclined inner circumferential surfaces 632b and 636b are formed between them.

The inclined inner circumferential surfaces 632b and 636b are intended to cope with a situation in which the guide may be shaken during transportation. That is, the inclined inner circumferential surfaces 632b and 636b serve to guide and insert the shaft center of the guide so as to coincide with the shaft center of the rack bar even when the guide is carried in an eccentric state.

As shown in FIG. 9, the holder grips 652 and 656 are semi-circular separation hollow types, and have a 'U' cross section shape and a 'V' cross section shape to compress the left and right circumferential surfaces of the rack bar 601. , Any one of the grip grooves selected from the inclined cross-sectional shape.

3A to 9, it will be described in detail the operation method of the module main body 600 of the steering system assembly system of the present invention.

The module body 600 is interlocked with the first routine C1, the second routine C2, and the third routine C3, which are performed in the above-described automotive component assembly 100.

During operation of the first routine C1, the module main body 600 maintains the insertion guide part 630, the holder part 650, and the elevator part 680 in a standby state.

In the standby state, the induction part 630 and the holder part 650 open the guide bushings 632 and 636 and the holder grips 652 and 656, respectively, and the elevator part 680 pushes the pusher 681. I place it in a waiting position.

For this reason, the first routine (C1) that the rack bar 601 is mounted on the vertical workbench 610, and the second routine (C2) that is inserted after the guide 410 surrounds the rack bar 601, and Then, in any case of the third routine C3 in which the inner seal 201 is lightly seated on the guide 410, the pusher 681, the guide bushings 632 and 636, and the holder grips 652 and 656 serve as obstacles. It doesn't work.

First, the rack bar 601 is set according to the specifications of the rack bar 601 from the movable rack bar mounting fixtures 672 and 673 or the fixed rack bar mount 671 of the vertical work bench 610 by an external industrial robot R. It is erected in the rack bar seating grooves (671a, 676a) of the place.

The holder part 650 compresses the rack bar 601 while moving the holder grips 652 and 656 in the direction in which the holders are combined with each other. Temporarily fix until it is over.

The insertion guide part 630 is moved and stopped in the direction in which the guide bushings 632 and 636 are joined to each other to be integrated in a hollow shape.

When incorporated in this way, the guide bushings 632 and 636 wrap the upper end of the rack bar 601 into the lower portion of its central radii 632c and 636c, and at the same time, the inclined inner circumferential surface above the central radii 632c and 636c. 632b and 636b become a cone shape.

Then, the robot arm of the industrial robot (R) is released from the rack bar 601 was held and then separated from the vertical workbench (610).

Through the second routine C2, the guide insertion module 400 lifts only the inspected guide 410 with a tong-type loader and transports it to the vertical work bench 610 of the module main body 600, and the guide 410 thus carried. ) Stops on the vertical top of the guide bushings 632 and 636 and immediately lowers the guide 410 with a tong type loader.

The lower end of the guide 410 is lowered, while the guide bushings 632 and 636 are in contact with the inclined inner circumferential surfaces 632b and 636b having a conical shape, the shaft center of the guide 410 gradually becomes the shaft center of the rack bar 601. To match.

The insertion guide 630 shortens the shaft lengths of the operating shafts of the left and right actuators 631 and 635 immediately after completing the role of inducing the guide 410 to match the shaft center of the rack bar 601. , 636 is separated from each other and at the same time return to the original position, so as not to interfere with the descending progress of the forceps-type loader of the guide insertion module 400 continues.

At the time when the clamp-type loader of the guide insertion module 400 passes safely through the insertion guide part 630, the guide 410 held by the clamp-type loader is inserted to surround the rack gear of the rack bar 601 and its peripheral portion.

Thereafter, the clip-type loader of the guide insertion module 400 is released and guided for the next step after releasing the guide 410.

Through the third routine C3, the inner seal supply device 300 carries the inner seal 201 from the magazine module 200 to the module main body 600, and performs the inner seal inspection and oil coating.

The inner seal supply device 300 gently seats the inner seal 201 for final assembly coated with oil to the guide 410 of the rack bar 601 of the vertical work bench 610 and returns for the next work.

The elevator 680 then advances the pusher 681 with its horizontal actuator 686 by a horizontal reciprocating transfer distance g from the pusher standby position to linearly move to the pusher top dead center start position.

In addition, the elevator unit 680 descends and stops the pusher 681 by the lifting actuator 683 along the operation groove 612 from the pusher top dead center start position to the pusher bottom dead center stop position.

In this case, the inner seal 201 swept away by the pusher 681 is smoothly moved downwards as if sliding on the outer peripheral surfaces of the guide 410 and the rack bar 601 by the applied oil, and then the stop of the pusher 681 is stopped. At the same time, the rack bar 601 is disposed at a predetermined inner seal assembly position.

Thereafter, the elevator unit 680 raises the pusher 681 by the stroke distance S, and then moves back by the horizontal reciprocating transfer distance g.

Finally, as described in the first routine C1, the industrial robot R separates the rack bar inner seal assembly from the vertical workbench 610 and transports it to the rack bar inner inner assembly storage site on the other side.

This assembly process is performed repeatedly during the rack bar inner seal assembly process.

In the present invention as described above, in the automated mass assembly work of the rack bar and the inner seal, the inner seal can be quickly inserted into the guided rack bar, and the effect of providing a steering system assembly system capable of securing technical reliability is provided. have.

In addition, the steering system assembly system of the present invention, as the vertical workbench is installed in the auto parts assembly machine, the industrial robot around it can easily and quickly load and unload the rack bar or rack bar inner seal assembly of the non-assembled state There is an advantage to this.
